A Study in Scarlet is the short mystery novel (probably a novella, although I didn't count words) that introduced the world to Sherlock Holmes. I'm going to invoke the 100-year-rule and discuss the plot of this book rather freely on the grounds that even someone who (like me prior to a few days ago) has not yet read it is probably not that invested in avoiding all spoilers. If you do want to remain entirely unspoiled, exercise caution before reading on. I had somehow managed to avoid ever reading anything by Arthur Conan Doyle, not even a short story. I therefore couldn't be sure that some of the assertions I was making in my review of A Study in Honor were correct. Since A Study in Scarlet would be quick to read, I decided on a whim to do a bit of research and grab a free copy of the first Holmes novel. Holmes is such a part of English-speaking culture that I thought I had a pretty good idea of what to expect. This was largely true, but cultural osmosis had somehow not prepared me for the surprise Mormons. A Study in Scarlet establishes the basic parameters of a Holmes story: Dr. James Watson as narrator, the apartment he shares with Holmes at 221B Baker Street, the Baker Street Irregulars, Holmes's competition with police detectives, and his penchant for making leaps of logical deduction from subtle clues. The story opens with Watson meeting Holmes, agreeing to split the rent of a flat, and being baffled by the apparent randomness of Holmes's fields of study before Holmes reveals he's a consulting detective. The first case is a murder: a man is found dead in an abandoned house, without a mark on him although there are blood splatters on the walls and the word "RACHE" written in blood. Since my only prior exposure to Holmes was from cultural references and a few TV adaptations, there were a few things that surprised me. One is that Holmes is voluble and animated rather than aloof. Doyle is clearly going for passionate eccentric rather than calculating mastermind. Another is that he is intentionally and unabashedly ignorant on any topic not related to solving mysteries.

My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar System. That any civilized human being in this nineteenth century should not be aware that the earth travelled round the sun appeared to be to me such an extraordinary fact that I could hardly realize it. "You appear to be astonished," he said, smiling at my expression of surprise. "Now that I do know it I shall do my best to forget it." "To forget it!" "You see," he explained, "I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you chose. A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best is jumbled up with a lot of other things so that he has a difficulty in laying his hands upon it. Now the skilful workman is very careful indeed as to what he takes into his brain-attic. He will have nothing but the tools which may help him in doing his work, but of these he has a large assortment, and all in the most perfect order. It is a mistake to think that that little room has elastic walls and can distend to any extent. Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones."

This is directly contrary to my expectation that the best way to make leaps of deduction is to know something about a huge range of topics so that one can draw unexpected connections, particularly given the puzzle-box construction and odd details so beloved in classic mysteries. I'm now curious if Doyle stuck with this conception, and if there were any later mysteries that involved astronomy. Speaking of classic mysteries, A Study in Scarlet isn't quite one, although one can see the shape of the genre to come. Doyle does not "play fair" by the rules that have not yet been invented. Holmes at most points knows considerably more than the reader, including bits of evidence that are not described until Holmes describes them and research that Holmes does off-camera and only reveals when he wants to be dramatic. This is not the sort of story where the reader is encouraged to try to figure out the mystery before the detective. Rather, what Doyle seems to be aiming for, and what Watson attempts (unsuccessfully) as the reader surrogate, is slightly different: once Holmes makes one of his grand assertions, the reader is encouraged to guess what Holmes might have done to arrive at that conclusion. Doyle seems to want the reader to guess technique rather than outcome, while providing only vague clues in general descriptions of Holmes's behavior at a crime scene. The structure of this story is quite odd. The first part is roughly what you would expect: first-person narration from Watson, supposedly taken from his journals but not at all in the style of a journal and explicitly written for an audience. Part one concludes with Holmes capturing and dramatically announcing the name of the killer, who the reader has never heard of before. Part two then opens with... a western?

In the central portion of the great North American Continent there lies an arid and repulsive desert, which for many a long year served as a barrier against the advance of civilization. From the Sierra Nevada to Nebraska, and from the Yellowstone River in the north to the Colorado upon the south, is a region of desolation and silence. Nor is Nature always in one mood throughout the grim district. It comprises snow-capped and lofty mountains, and dark and gloomy valleys. There are swift-flowing rivers which dash through jagged ca ons; and there are enormous plains, which in winter are white with snow, and in summer are grey with the saline alkali dust. They all preserve, however, the common characteristics of barrenness, inhospitality, and misery.

First, I have issues with the geography. That region contains some of the most beautiful areas on earth, and while a lot of that region is arid, describing it primarily as a repulsive desert is a bit much. Doyle's boundaries and distances are also confusing: the Yellowstone is a northeast-flowing river with its source in Wyoming, so the area between it and the Colorado does not extend to the Sierra Nevadas (or even to Utah), and it's not entirely clear to me that he realizes Nevada exists. This is probably what it's like for people who live anywhere else in the world when US authors write about their country. But second, there's no Holmes, no Watson, and not even the pretense of a transition from the detective novel that we were just reading. Doyle just launches into a random western with an omniscient narrator. It features a lean, grizzled man and an adorable child that he adopts and raises into a beautiful free spirit, who then falls in love with a wild gold-rush adventurer. This was written about 15 years before the first critically recognized western novel, so I can't blame Doyle for all the cliches here, but to a modern reader all of these characters are straight from central casting. Well, except for the villains, who are the Mormons. By that, I don't mean that the villains are Mormon. I mean Brigham Young is the on-page villain, plotting against the hero to force his adopted daughter into a Mormon harem (to use the word that Doyle uses repeatedly) and ruling Salt Lake City with an iron hand, border guards with passwords (?!), and secret police. This part of the book was wild. I was laughing out-loud at the sheer malevolent absurdity of the thirty-day countdown to marriage, which I doubt was the intended effect. We do eventually learn that this is the backstory of the murder, but we don't return to Watson and Holmes for multiple chapters. Which leads me to the other thing that surprised me: Doyle lays out this backstory, but then never has his characters comment directly on the morality of it, only the spectacle. Holmes cares only for the intellectual challenge (and for who gets credit), and Doyle sets things up so that the reader need not concern themselves with aftermath, punishment, or anything of that sort. I probably shouldn't have been surprised this does fit with the Holmes stereotype but I'm used to modern fiction where there is usually at least some effort to pass judgment on the events of the story. Doyle draws very clear villains, but is utterly silent on whether the murder is justified. Given its status in the history of literature, I'm not sorry to have read this book, but I didn't particularly enjoy it. It is very much of its time: everyone's moral character is linked directly to their physical appearance, and Doyle uses the occasional racial stereotype without a second thought. Prevailing writing styles have changed, so the prose feels long-winded and breathless. The rivalry between Holmes and the police detectives is tedious and annoying. I also find it hard to read novels from before the general absorption of techniques of emotional realism and interiority into all genres. The characters in A Study in Scarlet felt more like cartoon characters than fully-realized human beings. I have no strong opinion about the objective merits of this book in the context of its time other than to note that the sudden inserted western felt very weird. My understanding is that this is not considered one of the better Holmes stories, and Holmes gets some deeper characterization later on. Maybe I'll try another of Doyle's works someday, but for now my curiosity has been sated. Followed by The Sign of the Four. Rating: 4 out of 10

This is a post I wrote in June 2022, but did not publish back then. After first publishing it in December 2023, a perfectionist insecure part of me unpublished it again. After receiving positive feedback, i slightly amended and republish it now. In this post, I talk about unpaid work in F/LOSS, taking on the example of hackathons, and why, in my opinion, the expectation of volunteer work is hurting diversity. Disclaimer: I don t have all the answers, only some ideas and questions.

Previous findings In 2006, the Flosspols survey searched to explain the role of gender in free/libre/open source software (F/LOSS) communities because an earlier [study] revealed a significant discrepancy in the proportion of men to women. It showed that just about 1.5% of F/LOSS community members were female at that time, compared with 28% in proprietary software (which is also a low number). Their key findings were, to name just a few:

• that F/LOSS rewards the producing code rather than the producing software. It thereby puts most emphasis on a particular skill set. Other activities such as interface design or documentation are understood as less technical and therefore less prestigious.
• The reliance on long hours of intensive computing in writing successful code means that men, who in general assume that time outside of waged labour is theirs , are freer to participate than women, who normally still assume a disproportionate amount of domestic responsibilities. Female F/LOSS participants, however, seem to be able to allocate a disproportionate larger share of their leisure time for their F/LOSS activities. This gives an indication that women who are not able to spend as much time on voluntary activities have difficulties to integrate into the community.

We also know from the 2016 Debian survey, published in 2021, that a majority of Debian contributors are employed, rather than being contractors, and rather than being students. Also, 95.5% of respondents to that study were men between the ages of 30 and 49, highly educated, with the largest groups coming from Germany, France, USA, and the UK. The study found that only 20% of the respondents were being paid to work on Debian. Half of these 20% estimate that the amount of work on Debian they are being paid for corresponds to less than 20% of the work they do there. On the other side, there are 14% of those who are being paid for Debian work who declared that 80-100% of the work they do in Debian is remunerated.

So, if a majority of people is not paid, why do they work on F/LOSS? Or: What are the incentives of free software? In 2021, Louis-Philippe V ronneau aka Pollo, who is not only a Debian Developer but also an economist, published his thesis What are the incentive structures of free software (The actual thesis was written in French). One very interesting finding Pollo pointed out is this one:

Indeed, while we have proven that there is a strong and significative correlation between the income and the participation in a free/libre software project, it is not possible for us to pronounce ourselves about the causality of this link.

In the French original text:

En effet, si nous avons prouv qu il existe une corr lation forte et significative entre le salaire et la participation un projet libre, il ne nous est pas possible de nous prononcer sur la causalit de ce lien.

Said differently, it is certain that there is a relationship between income and F/LOSS contribution, but it s unclear whether working on free/libre software ultimately helps finding a well paid job, or if having a well paid job is the cause enabling work on free/libre software. I would like to scratch this question a bit further, mostly relying on my own observations, experiences, and discussions with F/LOSS contributors.

Volunteer work is unpaid work We often hear of hackathons, hack weeks, or hackfests. I ve been at some such events myself, Tails organized one, the IETF regularly organizes hackathons, and last week (June 2022!) I saw an invitation for a hack week with the Torproject. This type of event generally last several days. While the people who organize these events are being paid by the organizations they work for, participants on the other hand are generally joining on a volunteer basis. Who can we expect to show up at this type of event under these circumstances as participants? To answer this question, I collected some ideas:

• people who have an employer sponsoring their work
• people who have a funder/grant sponsoring their work
• people who have a high income and can take time off easily (in that regard, remember the Gender Pay Gap, women often earn less for the same work than men)
• people who rely on family wealth (living off an inheritance, living on rights payments from a famous grandparent - I m not making these situations up, there are actual people in such financially favorable situations )
• people who don t need much money because they don t have to pay rent or pay low rent (besides house owners that category includes people who live in squats or have social welfare paying for their rent, people who live with parents or caretakers)
• people who don t need to do care work (for children, elderly family members, pets. Remember that most care work is still done by women.)
• students who have financial support or are in a situation in which they do not yet need to generate a lot of income
• people who otherwise have free time at their disposal

So, who, in your opinion, fits these unwritten requirements? Looking at this list, it s pretty clear to me why we d mostly find white men from the Global North, generally with higher education in hackathons and F/LOSS development. ( Great, they re a culture fit! ) Yes, there will also always be some people of marginalized groups who will attend such events because they expect to network, to find an internship, to find a better job in the future, or to add their participation to their curriculum. To me, this rings a bunch of alarm bells.

Low diversity in F/LOSS projects a mirror of the distribution of wealth I believe that the lack of diversity in F/LOSS is first of all a mirror of the distribution of wealth on a larger level. And by wealth I m referring to financial wealth as much as to social wealth in the sense of Bourdieu: Families of highly educated parents socially reproducing privilege by allowing their kids to attend better schools, supporting and guiding them in their choices of study and work, providing them with relations to internships acting as springboards into well paid jobs and so on. That said, we should ask ourselves as well:

Do F/LOSS projects exacerbate existing lines of oppression by relying on unpaid work? Let s look again at the causality question of Pollo s research (in my words):

It is unclear whether working on free/libre software ultimately helps finding a well paid job, or if having a well paid job is the cause enabling work on free/libre software.

Maybe we need to imagine this cause-effect relationship over time: as a student, without children and lots of free time, hopefully some money from the state or the family, people can spend time on F/LOSS, collect experience, earn recognition - and later find a well-paid job and make unpaid F/LOSS contributions into a hobby, cementing their status in the community, while at the same time generating a sense of well-being from working on the common good. This is a quite common scenario. As the Flosspols study revealed however, boys often get their own computer at the age of 14, while girls get one only at the age of 20. (These numbers might be slightly different now, and possibly many people don t own an actual laptop or desktop computer anymore, instead they own mobile devices which are not exactly inciting them to look behind the surface, take apart, learn, appropriate technology.) In any case, the above scenario does not allow for people who join F/LOSS later in life, eg. changing careers, to find their place. I believe that F/LOSS projects cannot expect to have more women, people of color, people from working class backgrounds, people from outside of Germany, France, USA, UK, Australia, and Canada on board as long as volunteer work is the status quo and waged labour an earned privilege.

Wait, are you criticizing all these wonderful people who sacrifice their free time to work towards common good? No, that s definitely not my intention, I m glad that F/LOSS exists, and the F/LOSS ecosystem has always represented a small utopia to me that is worth cherishing and nurturing. However, I think we still need to talk more about the lack of diversity, and investigate it further.

Paid internships are one key to countering lines of oppression Lots of projects, even Outreachy and GSoC, require one contribution to F/LOSS to be made prior to be able to apply for a paid internship. I do well understand the incentive of this, but it s quite a high entry barrier. In 2014/2015 I was able to have 3 months of work on Debian paid for via an Outreachy internship. I was extremely grateful for that opportunity because without this paid internship I would never have found the time to engage with the Debian and F/LOSS ecosystem in depth simply because I would have had to work on my usual day job; I have rent to pay, and a health insurance which is really not cheap. These programs are key because they help counter existing lines of oppression at a strategic point: they buy someone s time by providing them a small income. Back then, the internship was paid 5,500USD gross for 3 months, meaning after taxes and paying social/health insurance, I was left with roughly 1100 per month, really not much money for living decently in Western Europe, but enough to get started. By the way, to my knowledge, 4 women who did an Outreachy internship subsequently became Debian Developers. 3 other female Debian Developers are or were part of Outreachy on the organizer side. I think this shows that this program is a success that we don t celebrate enough!

Some types of work are never being paid Besides free work at hacking events, let me also underline that a lot of work in F/LOSS is not considered payable work (yes, that s an oxymoron!). Which F/LOSS project for example, has ever paid translators a decent fee? Which project has ever considered that doing the social glue work, often done by women in the projects, is work that should be paid for? Which F/LOSS projects pay the people who do their Debian packaging rather than relying on yet another already well-paid white man who can afford doing this work for free all the while holding up how great the F/LOSS ecosystem is? And how many people on opensourcedesign jobs are looking to get their logo or website done for free? (Isn t that heart icon appealing to your altruistic empathy?) In my experience even F/LOSS projects which are trying to do the right thing by paying everyone the same amount of money per hour run into issues when it turns out that not all hours are equal and that some types of work do not qualify for remuneration at all or that the rules for the clocking of work are not universally applied in the same way by everyone.

Not every interaction should have a monetary value, but Some of you want to keep working without being paid, because that feels a bit like communism within capitalism, it makes you feel good to contribute to the greater good while not having the system determine your value over money. I hear you. I ve been there (and sometimes still am). But as long as we live in this system, even though we didn t choose to and maybe even despise it - communism is not about working for free, it s about getting paid equally and adequately. We may not think about it while under the age of 40 or 45, but working without adequate financial compensation, even half of the time, will ultimately result in not being able to care for oneself when sick, when old. And while this may not be an issue for people who inherit wealth, or have an otherwise safe economical background, eg. an academic salary, it is a huge problem and barrier for many people coming out of the working or service classes. (Oh and please, don t repeat the neoliberal lie that everyone can achieve whatever they aim for, if they just tried hard enough. French research shows that (in France) one has only 30% chance to become a class defector , and change social class upwards. But I managed to get out and move up, so everyone can! - well, if you believe that I m afraid you might be experiencing survivor bias.)

Not all bodies are equally able We should also be aware that not all of us can work with the same amount of energy either. There is yet another category of people who are excluded by the expectation of volunteer work, either because the waged labour they do already eats all of their energy, or because their bodies are not disposed to do that much work, for example because of mental health issues - such as depression-, or because of physical disabilities.

When organizing events relying on volunteer work please think about these things. Yes, you can tell people that they should ask their employer to pay them for attending a hackathon - but, as I ve hopefully shown, that would not do it for many people, especially newcomers. Instead, you could propose a fund to make it possible that people who would not normally attend can attend. DebConf is a good example for having done this for many years.

Conclusively I would like to urge free software projects that have a budget and directly pay some people from it to map where they rely on volunteer work and how this hurts diversity in their project. How do you or your project exacerbate pre-existing lines of oppression by granting or not granting monetary value to certain types of work? What is it that you take for granted? As always, I m curious about your feedback!

Worth a read These ideas are far from being new. Ashe Dryden s well-researched post The ethics of unpaid labor and the OSS community dates back to 2013 and is as important as it was ten years ago.

I have accidentally rewritten screentest, an old X11/GTK2 program that I was previously using to, well, test screens.

Screentest is dead It was removed from Debian in May 2023 but had already missed two releases (Debian 11 "bullseye" and 12 "bookworm") due to release critical bugs. The stated reason for removal was:

The package is orphaned and its upstream is no longer developed. It depends on gtk2, has a low popcon and no reverse dependencies.

So I had little hope to see this program back in Debian. The git repository shows little activity, the last being two years ago. Interestingly, I do not quite remember what it was testing, but I do remember it to find dead pixels, confirm native resolution, and various pixel-peeping. Here's a screenshot of one of the screentest screens: Now, I think it's safe to assume this program is dead and buried, and anyways I'm running wayland now, surely there's something better? Well, no. Of course not. Someone would know about it and tell me before I go on a random coding spree in a fit of procrastination... riiight? At least, the Debconf video team didn't seem to know of any replacement. They actually suggested I just "invoke gstreamer directly" and "embrace the joy of shell scripting".

Screentest reborn So, I naively did exactly that and wrote a horrible shell script. Then I realized the next step was to write an command line parser and monitor geometry guessing, and thought "NOPE, THIS IS WHERE THE SHELL STOPS", and rewrote the whole thing in Python. Now, screentest lives as a ~400-line Python script, half of which is unit test data and command-line parsing.

Why screentest Some smarty pants is going to complain and ask why the heck one would need something like that (and, well, someone already did), so maybe I can lay down a list of use case:

• testing color output, in broad terms (answering the question of "is it just me or this project really yellow?")
• testing focus and keystone ("this looks blurry, can you find a nice sharp frame in that movie to adjust focus?")
• test for native resolution and sharpness ("does this projector really support 4k for 30$? that sounds like bullcrap")
• looking for dead pixels ("i have a new monitor, i hope it's intact")

What does screentest do? Screentest displays a series of "patterns" on screen. The list of patterns is actually hardcoded in the script, copy-pasted from this list from the videotestsrc gstreamer plugin, but you can pass any pattern supported by your gstreamer installation with --patterns. A list of patterns relevant to your installation is available with the gst-inspect-1.0 videotestsrc command. By default, screentest goes through all patterns. Each pattern runs indefinitely until the you close the window, then the next pattern starts. You can restrict to a subset of patterns, for example this would be a good test for dead pixels:

screentest --patterns black,white,red,green,blue

This would be a good sharpness test:

screentest --patterns pinwheel,spokes,checkers-1,checkers-2,checkers-4,checkers-8

A good generic test is the classic SMPTE color bars and is the first in the list, but you can run only that test with:

screentest --patterns smpte

(I will mention, by the way, that as a system administrator with decades of experience, it is nearly impossible to type SMPTE without first typing SMTP and re-typing it again a few times before I get it right. I fully expect this post to have numerous typos.)

Here's an example of the SMPTE pattern from Wikipedia: For multi-monitor setups, screentest also supports specifying which output to use as a native resolution, with --output. Failing that, it will try to look at the outputs and use the first it will find. If it fails to find anything, you can specify a resolution with --resolution WIDTHxHEIGHT. I have tried to make it go full screen by default, but stumbled a bug in Sway that crashes gst-launch. If your Wayland compositor supports it, you can possibly enable full screen with --sink waylandsink fullscreen=true. Otherwise it will create a new window that you will have to make fullscreen yourself. For completeness, there's also an --audio flag that will emit the classic "drone", a sine wave at 440Hz at 40% volume (the audiotestsrc gstreamer plugin. And there's a --overlay-name option to show the pattern name, in case you get lost and want to start with one of them again.

How this works Most of the work is done by gstreamer. The script merely generates a pipeline and calls gst-launch to show the output. That both limits what it can do but also makes it much easier to use than figuring out gst-launch. There might be some additional patterns that could be useful, but I think those are better left to gstreamer. I, for example, am somewhat nostalgic of the Philips circle pattern that used to play for TV stations that were off-air in my area. But that, in my opinion, would be better added to the gstreamer plugin than into a separate thing. The script shows which command is being ran, so it's a good introduction to gstreamer pipelines. Advanced users (and the video team) will possibly not need screentest and will design their own pipelines with their own tools. I've previously worked with ffmpeg pipelines (in another such procrastinated coding spree, video-proxy-magic), and I found gstreamer more intuitive, even though it might be slightly less powerful. In retrospect, I should probably have picked a new name, to avoid crashing the namespace already used by the project, which is now on GitHub. Who knows, it might come back to life after this blog post; it would not be the first time. For now, the project lives along side the rest of my scripts collection but if there's sufficient interest, I might move it to its own git repositories. Comments, feedback, contributions are as usual welcome. And naturally, if you know something better for this kind of stuff, I'm happy to learn more about your favorite tool! So now I have finally found something to test my projector, which will likely confirm what I've already known all along: that it's kind of a piece of crap and I need to get a proper one.

Nextcloud is a popular self-hosted solution for file sync and share as well as cloud apps such as document editing, chat and talk, calendar, photo gallery etc. This guide will walk you through setting up Nextcloud AIO using Docker Compose. This blog post would not be possible without immense help from Sahil Dhiman a.k.a. sahilisterThere are various ways in which the installation could be done, in our setup here are the pre-requisites.

• A server with docker-compose installed
• An existing setup of nginx reverse proxy
• A domain name pointing to your server.

Step 1 : The docker-compose file for nextcloud AIOThe original compose.yml file is present in nextcloud AIO&aposs git repo here . By taking a reference of that file, we have own compose.yml here.

I am using a separate directory to store nextcloud data. As per nextcloud documentation you should be using a separate partition if you want to use this feature, however I did not have that option on my server, so I used a separate directory instead. Also we use a custom port on which nextcloud listens for operations, we have set it up as 32323 above, but you can use any in the permissible port range. The 8080 port is used the setup the AIO management interface. Both 8080 and the APACHE_PORT do not need to be open on the host machine, as we will be using reverse proxy setup with nginx to direct requests. once you have your preferred compose.yml file, you can start the containers using

$ docker-compose -f compose.yml up -d 
Creating network "clouddev_default" with the default driver
Creating volume "nextcloud_aio_mastercontainer" with default driver
Creating nextcloud-aio-mastercontainer ... done

once your container&aposs are running, we can do the nginx setup.

Step 2: Configuring nginx reverse proxy for our domain on host. A reference nginx configuration for nextcloud AIO is given in the nextcloud git repository here . You can modify the configuration file according to your needs and setup. Here is configuration that we are using

map $http_upgrade $connection_upgrade  
    default upgrade;
    &apos&apos close;
 
server  
    listen 80;
    #listen [::]:80;            # comment to disable IPv6
    if ($scheme = "http")  
        return 301 https://$host$request_uri;
     
    listen 443 ssl http2;      # for nginx versions below v1.25.1
    #listen [::]:443 ssl http2; # for nginx versions below v1.25.1 - comment to disable IPv6
    # listen 443 ssl;      # for nginx v1.25.1+
    # listen [::]:443 ssl; # for nginx v1.25.1+ - keep comment to disable IPv6
    # http2 on;                                 # uncomment to enable HTTP/2        - supported on nginx v1.25.1+
    # http3 on;                                 # uncomment to enable HTTP/3 / QUIC - supported on nginx v1.25.0+

Please note that you need to have valid SSL certificates for your domain for this configuration to work. Steps on getting valid SSL certificates for your domain are beyond the scope of this article. You can give a web search on getting SSL certificates with letsencrypt and you will get several resources on that, or may write a blog post on it separately in the future.once your configuration for nginx is done, you can test the nginx configuration using

$ sudo nginx -t 
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

and then reload nginx with

$ sudo nginx -s reload

Step 3: Setup of Nextcloud AIO from the browser.To setup nextcloud AIO, we need to access it using the web browser on URL of our domain.tld:8080, however we do not want to open the 8080 port publicly to do this, so to complete the setup, here is a neat hack from sahilister

ssh -L 8080:127.0.0.1:8080 username:<server-ip>

you can bind the 8080 port of your server to the 8080 of your localhost using Unix socket forwarding over SSH.The port forwarding only last for the duration of your SSH session, if the SSH session breaks, your port forwarding will to. So, once you have the port forwarded, you can open the nextcloud AIO instance in your web browser at 127.0.0.1:8080

you will get this error because you are trying to access a page on localhost over HTTPS. You can click on advanced and then continue to proceed to the next page. Your data is encrypted over SSH for this session as we are binding the port over SSH. Depending on your choice of browser, the above page might look different.once you have proceeded, the nextcloud AIO interface will open and will look something like this.

nextcloud AIO initial screen with capsicums as password

It will show an auto generated passphrase, you need to save this passphrase and make sure to not loose it. For the purposes of security, I have masked the passwords with capsicums. once you have noted down your password, you can proceed to the Nextcloud AIO login, enter your password and then login. After login you will be greeted with a screen like this.

now you can put the domain that you want to use in the Submit domain field. Once the domain check is done, you will proceed to the next step and see another screen like this

here you can select any optional containers for the features that you might want. IMPORTANT: Please make sure to also change the time zone at the bottom of the page according to the time zone you wish to operate in.

The timezone setup is also important because the data base will get initialized according to the set time zone. This could result in wrong initialization of database and you ending up in a startup loop for nextcloud. I faced this issue and could only resolve it after getting help from sahilister . Once you are done changing the timezone, and selecting any additional features you want, you can click on Download and start the containersIt will take some time for this process to finish, take a break and look at the farthest object in your room and take a sip of water. Once you are done, and the process has finished you will see a page similar to the following one.

wait patiently for everything to turn green.

once all the containers have started properly, you can open the nextcloud login interface on your configured domain, the initial login details are auto generated as you can see from the above screenshot. Again you will see a password that you need to note down or save to enter the nextcloud interface. Capsicums will not work as passwords. I have masked the auto generated passwords using capsicums.Now you can click on Open your Nextcloud button or go to your configured domain to access the login screen.

You can use the login details from the previous step to login to the administrator account of your Nextcloud instance. There you have it, your very own cloud!

Additional Notes:

How to properly reset Nextcloud setup?While following the above steps, or while following steps from some other tutorial, you may have made a mistake, and want to start everything again from scratch. The instructions for it are present in the Nextcloud documentation here . Here is the TLDR for a docker-compose setup. These steps will delete all data, do not use these steps on an existing nextcloud setup unless you know what you are doing.

• Stop your master container.

docker-compose -f compose.yml down -v

The above command will also remove the volume associated with the master container

• Stop all the child containers that has been started by the master container.

docker stop nextcloud-aio-apache nextcloud-aio-notify-push nextcloud-aio-nextcloud nextcloud-aio-imaginary nextcloud-aio-fulltextsearch nextcloud-aio-redis nextcloud-aio-database nextcloud-aio-talk nextcloud-aio-collabora

• Remove all the child containers that has been started by the master container

docker rm nextcloud-aio-apache nextcloud-aio-notify-push nextcloud-aio-nextcloud nextcloud-aio-imaginary nextcloud-aio-fulltextsearch nextcloud-aio-redis nextcloud-aio-database nextcloud-aio-talk nextcloud-aio-collabora

• If you also wish to remove all images associated with nextcloud you can do it with

docker rmi $(docker images --filter "reference=nextcloud/*" -q)

• remove all volumes associated with child containers

docker volume rm <volume-name>

• remove the network associated with nextcloud

docker network rm nextcloud-aio

Hello from a snowy Montr al! My life has been pretty busy lately¹ so please forgive this late report. On November 19th, our local Debian User Group met at Montreal's most prominent hackerspace, Foulab. We've been there a few times already, but since our last visit, Foulab has had some membership/financial troubles. Happy to say things are going well again and a new team has taken over the space. This meetup wasn't the most productive day for me (something about being exhausted apparently makes it hard to concentrate), but other people did a bunch of interesting stuff :)

• Kienan & Gabriel worked on the libinfluxdb-http-perl package (now in Sid!), which is needed for smokeping.
• J r me worked on updating JRuby to the latest upstream version.
• I failed to update monitoring-plugins-systemd to the latest upstream version. It seems the entire test suite has been re-written and I couldn't make it work in sbuild...
• Tiago and Tassia worked on the Debian Contributors website. More specifically, they added a DSA domains data source and created a scheduler on dcf.debian.net to make daily updates on the data sources in the dc-sources repository.
• Michael worked on the 2024 NorthSec badge.
• Gerard worked on debugging his broken AirGradient board.

Pictures Here are a bunch of pictures I took! Foulab is always a great place to snap quirky things :)

Ubuntu systems typically have up to 3 kernels installed, before they are auto-removed by apt on classic installs. Historically the installation was optimized for metered download size only. However, kernel size growth and usage no longer warrant such optimizations. During the 23.10 Mantic Minatour cycle, I led a coordinated effort across multiple teams to implement lots of optimizations that together achieved unprecedented install footprint improvements.

Given a typical install of 3 generic kernel ABIs in the default configuration on a regular-sized VM (2 CPU cores 8GB of RAM) the following metrics are achieved in Ubuntu 23.10 versus Ubuntu 22.04 LTS:

• 2x less disk space used (1,417MB vs 2,940MB, including initrd)

• 3x less peak RAM usage for the initrd boot (68MB vs 204MB)

• 0.5x increase in download size (949MB vs 600MB)

• 2.5x faster initrd generation (4.5s vs 11.3s)

• approximately the same total time (103s vs 98s, hardware dependent)

For minimal cloud images that do not install either linux-firmware or modules extra the numbers are:

• 1.3x less disk space used (548MB vs 742MB)

• 2.2x less peak RAM usage for initrd boot (27MB vs 62MB)

• 0.4x increase in download size (207MB vs 146MB)

Hopefully, the compromise of download size, relative to the disk space & initrd savings is a win for the majority of platforms and use cases. For users on extremely expensive and metered connections, the likely best saving is to receive air-gapped updates or skip updates.

This was achieved by precompressing kernel modules & firmware files with the maximum level of Zstd compression at package build time; making actual .deb files uncompressed; assembling the initrd using split cpio archives - uncompressed for the pre-compressed files, whilst compressing only the userspace portions of the initrd; enabling in-kernel module decompression support with matching kmod; fixing bugs in all of the above, and landing all of these things in time for the feature freeze. Whilst leveraging the experience and some of the design choices implementations we have already been shipping on Ubuntu Core. Some of these changes are backported to Jammy, but only enough to support smooth upgrades to Mantic and later. Complete gains are only possible to experience on Mantic and later.

The discovered bugs in kernel module loading code likely affect systems that use LoadPin LSM with kernel space module uncompression as used on ChromeOS systems. Hopefully, Kees Cook or other ChromeOS developers pick up the kernel fixes from the stable trees. Or you know, just use Ubuntu kernels as they do get fixes and features like these first.

The team that designed and delivered these changes is large: Benjamin Drung, Andrea Righi, Juerg Haefliger, Julian Andres Klode, Steve Langasek, Michael Hudson-Doyle, Robert Kratky, Adrien Nader, Tim Gardner, Roxana Nicolescu - and myself Dimitri John Ledkov ensuring the most optimal solution is implemented, everything lands on time, and even implementing portions of the final solution.

Review: Going Infinite, by Michael Lewis

Publisher:	W.W. Norton & Company
Copyright:	2023
ISBN:	1-324-07434-5
Format:	Kindle
Pages:	255

My first reaction when I heard that Michael Lewis had been embedded with Sam Bankman-Fried working on a book when Bankman-Fried's cryptocurrency exchange FTX collapsed into bankruptcy after losing billions of dollars of customer deposits was "holy shit, why would you talk to Michael Lewis about your dodgy cryptocurrency company?" Followed immediately by "I have to read this book." This is that book. I wasn't sure how Lewis would approach this topic. His normal (although not exclusive) area of interest is financial systems and crises, and there is lots of room for multiple books about cryptocurrency fiascoes using someone like Bankman-Fried as a pivot. But Going Infinite is not like The Big Short or Lewis's other financial industry books. It's a nearly straight biography of Sam Bankman-Fried, with just enough context for the reader to follow his life. To understand what you're getting in Going Infinite, I think it's important to understand what sort of book Lewis likes to write. Lewis is not exactly a reporter, although he does explain complicated things for a mass audience. He's primarily a storyteller who collects people he finds fascinating. This book was therefore never going to be like, say, Carreyrou's Bad Blood or Isaac's Super Pumped. Lewis's interest is not in a forensic account of how FTX or Alameda Research were structured. His interest is in what makes Sam Bankman-Fried tick, what's going on inside his head. That's not a question Lewis directly answers, though. Instead, he shows you Bankman-Fried as Lewis saw him and was able to reconstruct from interviews and sources and lets you draw your own conclusions. Boy did I ever draw a lot of conclusions, most of which were highly unflattering. However, one conclusion I didn't draw, and had been dubious about even before reading this book, was that Sam Bankman-Fried was some sort of criminal mastermind who intentionally plotted to steal customer money. Lewis clearly doesn't believe this is the case, and with the caveat that my study of the evidence outside of this book has been spotty and intermittent, I think Lewis has the better of the argument. I am utterly fascinated by this, and I'm afraid this review is going to turn into a long summary of my take on the argument, so here's the capsule review before you get bored and wander off: This is a highly entertaining book written by an excellent storyteller. I am also inclined to believe most of it is true, but given that I'm not on the jury, I'm not that invested in whether Lewis is too credulous towards the explanations of the people involved. What I do know is that it's a fantastic yarn with characters who are too wild to put in fiction, and I thoroughly enjoyed it. There are a few things that everyone involved appears to agree on, and therefore I think we can take as settled. One is that Bankman-Fried, and most of the rest of FTX and Alameda Research, never clearly distinguished between customer money and all of the other money. It's not obvious that their home-grown accounting software (written entirely by one person! who never spoke to other people! in code that no one else could understand!) was even capable of clearly delineating between their piles of money. Another is that FTX and Alameda Research were thoroughly intermingled. There was no official reporting structure and possibly not even a coherent list of employees. The environment was so chaotic that lots of people, including Bankman-Fried, could have stolen millions of dollars without anyone noticing. But it was also so chaotic that they could, and did, literally misplace millions of dollars by accident, or because Bankman-Fried had problems with object permanence. Something that was previously less obvious from news coverage but that comes through very clearly in this book is that Bankman-Fried seriously struggled with normal interpersonal and societal interactions. We know from multiple sources that he was diagnosed with ADHD and depression (Lewis describes it specifically as anhedonia, the inability to feel pleasure). The ADHD in Lewis's account is quite severe and does not sound controlled, despite medication; for example, Bankman-Fried routinely played timed video games while he was having important meetings, forgot things the moment he stopped dealing with them, was constantly on his phone or seeking out some other distraction, and often stimmed (by bouncing his leg) to a degree that other people found it distracting. Perhaps more tellingly, Bankman-Fried repeatedly describes himself in diary entries and correspondence to other people (particularly Caroline Ellison, his employee and on-and-off secret girlfriend) as being devoid of empathy and unable to access his own emotions, which Lewis supports with stories from former co-workers. I'm very hesitant to diagnose someone via a book, but, at least in Lewis's account, Bankman-Fried nearly walks down the symptom list of antisocial personality disorder in his own description of himself to other people. (The one exception is around physical violence; there is nothing in this book or in any of the other reporting that I've seen to indicate that Bankman-Fried was violent or physically abusive.) One of the recurrent themes of this book is that Bankman-Fried never saw the point in following rules that didn't make sense to him or worrying about things he thought weren't important, and therefore simply didn't. By about a third of the way into this book, before FTX is even properly started, very little about its eventual downfall will seem that surprising. There was no way that Sam Bankman-Fried was going to be able to run a successful business over time. He was extremely good at probabilistic trading and spotting exploitable market inefficiencies, and extremely bad at essentially every other aspect of living in a society with other people, other than a hit-or-miss ability to charm that worked much better with large audiences than one-on-one. The real question was why anyone would ever entrust this man with millions of dollars or decide to work for him for longer than two weeks. The answer to those questions changes over the course of this story. Later on, it was timing. Sam Bankman-Fried took the techniques of high frequency trading he learned at Jane Street Capital and applied them to exploiting cryptocurrency markets at precisely the right time in the cryptocurrency bubble. There was far more money than sense, the most ruthless financial players were still too leery to get involved, and a rising tide was lifting all boats, even the ones that were piles of driftwood. When cryptocurrency inevitably collapsed, so did his businesses. In retrospect, that seems inevitable. The early answer, though, was effective altruism. A full discussion of effective altruism is beyond the scope of this review, although Lewis offers a decent introduction in the book. The short version is that a sensible and defensible desire to use stronger standards of evidence in evaluating charitable giving turned into a bizarre navel-gazing exercise in making up statistical risks to hypothetical future people and treating those made-up numbers as if they should be the bedrock of one's personal ethics. One of the people most responsible for this turn is an Oxford philosopher named Will MacAskill. Sam Bankman-Fried was already obsessed with utilitarianism, in part due to his parents' philosophical beliefs, and it was a presentation by Will MacAskill that converted him to the effective altruism variant of extreme utilitarianism. In Lewis's presentation, this was like joining a cult. The impression I came away with feels like something out of a science fiction novel: Bankman-Fried knew there was some serious gap in his thought processes where most people had empathy, was deeply troubled by this, and latched on to effective altruism as the ethical framework to plug into that hole. So much of effective altruism sounds like a con game that it's easy to think the participants are lying, but Lewis clearly believes Bankman-Fried is a true believer. He appeared to be sincerely trying to make money in order to use it to solve existential threats to society, he does not appear to be motivated by money apart from that goal, and he was following through (in bizarre and mostly ineffective ways). I find this particularly believable because effective altruism as a belief system seems designed to fit Bankman-Fried's personality and justify the things he wanted to do anyway. Effective altruism says that empathy is meaningless, emotion is meaningless, and ethical decisions should be made solely on the basis of expected value: how much return (usually in safety) does society get for your investment. Effective altruism says that all the things that Sam Bankman-Fried was bad at were useless and unimportant, so he could stop feeling bad about his apparent lack of normal human morality. The only thing that mattered was the thing that he was exceptionally good at: probabilistic reasoning under uncertainty. And, critically to the foundation of his business career, effective altruism gave him access to investors and a recruiting pool of employees, things he was entirely unsuited to acquiring the normal way. There's a ton more of this book that I haven't touched on, but this review is already quite long, so I'll leave you with one more point. I don't know how true Lewis's portrayal is in all the details. He took the approach of getting very close to most of the major players in this drama and largely believing what they said happened, supplemented by startling access to sources like Bankman-Fried's personal diary and Caroline Ellis's personal diary. (He also seems to have gotten extensive information from the personal psychiatrist of most of the people involved; I'm not sure if there's some reasonable explanation for this, but based solely on the material in this book, it seems to be a shocking breach of medical ethics.) But Lewis is a storyteller more than he's a reporter, and his bias is for telling a great story. It's entirely possible that the events related here are not entirely true, or are skewed in favor of making a better story. It's certainly true that they're not the complete story. But, that said, I think a book like this is a useful counterweight to the human tendency to believe in moral villains. This is, frustratingly, a counterweight extended almost exclusively to higher-class white people like Bankman-Fried. This is infuriating, but that doesn't make it wrong. It means we should extend that analysis to more people. Once FTX collapsed, a lot of people became very invested in the idea that Bankman-Fried was a straightforward embezzler. Either he intended from the start to steal everyone's money or, more likely, he started losing money, panicked, and stole customer money to cover the hole. Lots of people in history have done exactly that, and lots of people involved in cryptocurrency have tenuous attachments to ethics, so this is a believable story. But people are complicated, and there's also truth in the maxim that every villain is the hero of their own story. Lewis is after a less boring story than "the crook stole everyone's money," and that leads to some bias. But sometimes the less boring story is also true. Here's the thing: even if Sam Bankman-Fried never intended to take any money, he clearly did intend to mix customer money with Alameda Research funds. In Lewis's account, he never truly believed in them as separate things. He didn't care about following accounting or reporting rules; he thought they were boring nonsense that got in his way. There is obvious criminal intent here in any reading of the story, so I don't think Lewis's more complex story would let him escape prosecution. He refused to follow the rules, and as a result a lot of people lost a lot of money. I think it's a useful exercise to leave mental space for the possibility that he had far less obvious reasons for those actions than that he was a simple thief, while still enforcing the laws that he quite obviously violated. This book was great. If you like Lewis's style, this was some of the best entertainment I've read in a while. Highly recommended; if you are at all interested in this saga, I think this is a must-read. Rating: 9 out of 10

I just had to setup a Brother MFC-J4440DW for a relative. They were replacing an old HP laser printer that mysteriously stopped printing as dark as it should, I don t know whether the HP printer had worn out or if the HP firmware decided to hobble it to make them buy a new printer. In either case HP is well known for shady behaviour with their printer firmware and should be avoided. The new Brother printer has problems when using wifi and auto DNS. I don t know how much of that was due to the printer itself and how much was due to the wifi AP provided by Foxtel. Anyway it works better with Ethernet and a fixed address (the wifi AP didn t allow me to set a fixed address). I think the main thing was configuring CUPS to connect via the IP address and not use Avahi etc. One problem I had with printing was that programs like Chrome and LibreOffice would hang for about a minute before printing, that turned out to be due to /etc/cups/lpoptions having the old printer (which had been removed) listed as the default. It would be nice if the web configuration for cups would change that when I set the default printer. CUPS doesn t seem to support USB printing. If it is possible to get this printer to print via USB then I welcome a comment describing how to do it. Scanning only seems to work on Ethernet not on USB, the command for scanning that I ended up with was scanimage -d escl:http://10.0.0.3:80 . Again I welcome comments from anyone who has had success in scanning via USB. There are probably some Linux users who would find it really inconvenient to setup a network interface specifically for printing. It s easy for me as I have a pile of spare ethernet cards and a box of cables but some people would have to buy this. Also it s disappointing that Brother didn t include an Ethernet cable or a USB cable in the box. But if that makes it cheaper I can deal with that. The resolution for scanning is only 832*1163 and it s black and white, I think that generally scanning in printers is a bad idea, taking a photo with a phone is a better way of scanning documents. Generally this printer works well and is cheap at only $299, a price for disposable hardware by today s standards. There are Debian packages from Brother for the printer. The scanner package looks like it just configures scanimage, and I m not sure whether the stock version of CUPS in Debian will do it without the Brother package. One thing I found interesting is that the package mfcj4440dwpdrv has the following shell code in the postinst to label for SE Linux:

if [ "$(which semanage 2> /dev/null)" != '' ];then
semanage fcontext -a -t cupsd_rw_etc_t '/opt/brother/Printers/mfcj4440dw/inf(/.*)?'
semanage fcontext -a -t bin_t          '/opt/brother/Printers/mfcj4440dw/lpd(/.*)?'
semanage fcontext -a -t bin_t          '/opt/brother/Printers/mfcj4440dw/cupswrapper(/.*)?'
if [ "$(which restorecon 2> /dev/null)" != '' ];then
restorecon -R /opt/brother/Printers/mfcj4440dw
fi
fi

This is the first time I ve seen a Debian package from a hardware vendor with SE Linux specific code. I can t just add those rules to the Debian policy as that would make the semanage commands fail to add an identical context spec will break the postinst. In the latest policy I m uploading to Debian/Unstable (version 2.20231010-1) there are the following 3 lines to deal with this, the first was already there for some time and the other 2 I just added:

/opt/brother/Printers/([^/]+/)?inf(/.*)?        gen_context(system_u:object_r:cupsd_rw_etc_t,s0)
/opt/brother/Printers/[^/]+/lpd(/.*)?   gen_context(system_u:object_r:bin_t,s0)
/opt/brother/Printers/[^/]+/cupswrapper(/.*)?   gen_context(system_u:object_r:bin_t,s0)

The Brother employee(s) who added the SE Linux code to their package are welcome to connect to me on LinkedIn.

Some time ago our LUG bought some things from soldered.com and while browsing around the website my SO and I decided to add a junk box to the order and see what we would get. Other than a few useful things, there were two mostly unpopulated boards for the inkplate 10 which would have been pretty hard to reuse as electronics. On the other hand, at 23 cm 18 cm they are a size that is reasonable for a book, and the slit near a long edge made them look suitable for the cover plates of a coptic bound book. Since the size isn t a standard one, I used some paper I already had in big (A1) sheet: Clairefontaine Dessin Croquis Blanc at 120 g/m , and cut 32 sheet 466 mm 182 mm big, to have room to trim the excess at the end and straighten the edges. This would make 8 signatures of 4 sheet each, for a total of 128 pages. The paper will make it suitable both as a notebook (where I ll write with liquid ink, of course, not ballpoints) or as a sketchbook for pencil (but not wet techniques). I could have added a few more signatures, but this felt already good enough, and the risk to end up with an half-empty notebook was non-trivial (I will already have to force myself to actually use it, rather than keep it for a good topic that will never be). First we finished depopulating the boards, using it as a desoldering exercise and trying (and not always succeeding) to save as many components as possible, even if most of them were too tiny for our current soldiering skills. And then I only had to sew the book, which was done mostly while watching the DebConf streams. And a couple of days later, trim and sand the pages, which as usual I could have done better, but, well, it works. The next time I do something like this I think I will have to add a couple more mm also to the height, to be able to trim also those edges. And now of course the Big Question is: what should I dedicate this notebook to? Will I actually use it? This year? This decade?

I forgot to write down the details back when it happened, but now that the surprise has been delivered I can write about it. Some time ago, I decided to make a small banner with the GL-Como penguin for a friend, because reasons. However, this friend has a big problem, he, well, is from Pisa (no, I m not from Leghorn, why do you ask?), and I had a screen printing kit, openclipart and no inhibitions. So, with the encouragement of a few friends who were in the secret, this happened. In two copies, because the first attempt at the print had issues. And yesterday we finally met that friend again, gave him all of the banners, and no violence happened, but he liked them :D If somebody is interested, the source image I used is on openclipart, with links to all of the sources I ve used. I don t remember exactly how it happened, but when I was working on the Pisani sign I also stumbled on the no dogs sign and decided that the world needed a mandatory cat sign, and well, here is the full set (all images are a link to the openclipart page).

The long running British¹ SF Magazine Interzone has a new home and new editor, Gareth Jelley, starting with issue 294. It's also got a swanky new format ("JB6"): a perfect-bound, paperback novel size, perfect for fitting into an oversize coat or jeans pocket for reading on the train. I started reading Interzone in around 2003, having picked up an issue (#176) from Feb 2002 that was languishing on the shelves in Forbidden Planet. Once I discovered it I wondered why it had taken me so long. That issue introduced me to Greg Egan. I bought a number of back issues on eBay, to grab issues with stories by people including Terry Pratchett, Iain Banks, Alastair Reynolds, and others. A short while later in early 2004, after 22 years, Interzone's owner and editorship changed from David Pringle to Andy Cox and TTA Press. I can remember the initial transition was very jarring: the cover emphasised expanding into coverage of Manga, Graphic Novels and Video Games (which ultimately didn't happen) but after a short period of experimentation it quickly settled down into a similarly fantastic read. I particularly liked the move to a smaller, perfect-bound form-factor in 2012. I had to double-check this but I'd been reading IZ throughout the TTA era and it lasted 18 years! Throughout that time I have discovered countless fantastic authors that I would otherwise never have experienced. Some (but by no means all) are Dominic Green, Daniel Kaysen, Chris Beckett, C cile Cristofari, Aliya Whiteley, Tim Major, Fran oise Harvey, Will McIntosh. Cox has now retired (after 100 issues and a tenure almost as long as Pringle) and handed the reins to Gareth Jelley/MYY Press, who have published their first issue, #294. Jelley is clearly putting a huge amount of effort into revitalizing the magazine. There's a new homepage at interzone.press but also companion internet presences: a plethora of digital content at interzone.digital, Interzone Socials (a novel idea), a Discord server, a podcast, and no doubt more. Having said that, the economics of small magazines have been perilous for a long time, and that hasn't changed, so I think the future of IZ (in physical format at least) is in peril. If you enjoy short fiction, fresh ideas, SF/F/Fantastika; why not try a subscription to Interzone, whilst you still can!

A long time ago, around the turn of the century, I was looking at some Useful Origami website and found a pattern for a document folder with a lot of pockets. And by a lot of pockets I really mean a lot! I immediately had to fold one, and then another one, and then a few others, both in a size suitable for business cards and as a folder for A4 sheets of paper. And then, a few years ago I needed a new document folder, and looked for these instructions, and couldn t find them anywhere. Luckily I still had some of the folders I had made, and the model was simple enough that I could unfold those and reconstruct the instructions. I tried to show them around to see if anybody knew where it came from, but had no results. Now that I ve prepared a new website for patterns for non-fiber crafts (and that I needed a new folder :D ) I ve decided to post those instructions on it, so that they will have a stable place to live on. And now that the #origami crowd on the fediverse has grown, maybe somebody will stumble on them and will remember where they come from: if you do, please let me know, with a comment if you re reading this on the fediverse, or through one of my contacts if you re reading the blog directly.

Since some time I ve been thinking about making myself a top or a dress with a wide gathered neckline that can be work at different widths, including off-the-shoulders. A few years ago I ve been gifted a cut of nice, thin white fabric with a print of lines and lozenges that isn t uniform along the fabric, but looks like it was designed for some specific garment, and it was waiting in my stash for a suitable pattern. And a few days ago, during a Sunday lunch, there was an off-hand mention of a dress from the late 1970s which had an elastic in the neckline, so that it could be optionally worn off-the-shoulders. And something snapped in place. I had plans for that afternoon, but they were scrapped, and I started to draw, measure, cut rectangles of fabric, pin and measure again, cut more fabric.

two rectangular tubes for the sleeves laid so that they meet the body just at the corners, and a triangle (a square gusset folded on the diagonal) joins them to the body.

I decided on a pattern made of rectangles to be able to use as much fabric as possible, with the size of each rectangle based mostly on the various sections on the print of the fabric. I ve made the typical sleeves from a rectangle and a square gusset, and then attached them to the body just from the gusset to keep the neckline wide and low. The part of the fabric with large vertical stripes had two different widths: I could have made the back narrower, but I decided to just keep a strip with narrower lines to one side. The fabric also didn t have a full second strip of lozenges, so I had to hem it halfway through it. The casing for the elastic was pieced from various scraps, but at least I was able to match the lines on the center front and back, even if they are different. Not that it matters a lot, since it s all hidden in the gathering, but I would have known. And since I was working on something definitely modern, even if made out of squares and rectangles, of course I decided to hand-sew everything, mostly to be able to use quite small sewing allowances, since the fabric was pretty thin. In my stash I had a piece of swimsuit elastic that feels nice, looks nice and makes a knot that doesn t slip, so I used it. It s a perfect match, except for the neon yellow colour, which I do like, but maybe is a bit too high visibility? I will see if the haberdasher has the same elastic in dark blue, but right now this will do. It was a quick project anyway: by the end of the working week the top was finished; I think that on a sewing machine it would be easy to make it in a day. And it can be worn off the shoulders! Which is something I will probably never do in public (and definitely not outdoors), but now if I wanted I could! :D As usual, the pattern (for what pattern there is) and instructions are on my pattern website under a #FreeSoftWear license, and I ve also added to the site a tip on how I use electrician fish tape to thread things through long casings

RISC -V Motherboard, SBC While I didn t want to, a part of me is hyped about this motherboard. This would probably be launched somewhere in November. There are obvious issues in this, the first being unlike regular motherboards you wouldn t be upgrade as you would do.You can t upgrade your memory, can t upgrade the CPU (although new versions of instructions could be uploaded, similar to BIOS updates) but as the hardware is integrated (the quad-core SiFive Performance P550 core complex) it would really depend. If the final pricing is around INR 4-5k then it may be able to sell handsomely provided there are people to push and provide support around it. A 500 GB or 1 TB SSD coupled with it and a cheap display unit and you could use it anywhere although as the name says it s more for tinkering as the name suggests. Another board that could perhaps be of more immediate use would be the beagleboard. They launched the same couple of days back and called it Beagle V-Ahead. Again, costs are going to be a concern. Just a year before the pandemic the Beagleboard Black (BB) used to cost in the sub 4k range, today it costs 8k+ for the end user, more than twice the price. How much Brexit is to be blamed for this and how much the Indian customs we would never know. The RS Group that is behind that shop is head-quartered in the UK. As said before, we do not know the price of either board as it probably will take few months for v-ahead to worm its way in the Indian market, maybe another 6 months or so. Even so, with the limited info. on both the boards, I am tilting more towards the other HiFive one. We should come to know about the boards say in 3-5 months of time.

CHIPS Act I had shared about the Chips Act a few times here as well as on SM. Two articles do tell how the CHIPS Act 2023 is more of a political tool, an industrial defence policy rather than just business as most people tend to think.

Cancelation of Books, Books Burning etc. Almost 2400 years ago, Plato released his work called Plato s Republic and one of the seminal works within it is perhaps one of the most famous works was the Allegory of the Cave. That is used again and again in a myriad ways, mostly in science-fiction though and mostly to do with utopian, dystopian movies, webseries etc. I did share how books are being canceled in the States, also a bit here. But the most damning thing has happened throughout history, huge quantities of books burned almost all for politics But part of it has been neglect as well as this time article shares. What we have lost and continue to lose is just priceless. Every book has a grain of truth in it, some more, some less but equally enjoyable. Most harmful is the neglect towards books and is more true today than any other time in history. Kids today have a wide variety of tools to keep themselves happy or occupied, from anime, VR, gaming the list goes on and on. In that scenario, how the humble books can compete. People think of Kindle but most e-readers like Kindle are nothing but obsolescence by design. I have tried out Kindle a few times but find it a bit on the flimsy side. Books are much better IMHO or call me old-school. While there are many advantages, one of the things that I like about books is that you can easily put yourself in either the protagonist or the antagonist or somewhere in the middle and think of the possible scenarios wherever you are in a particular book. I could go on but it will be a blog post or two in itself. Till later. Happy Reading.

Update:Manipur Extremely horrifying visuals, articles and statements continue to emanate from Manipur. Today, 19th July 2023, just couple of hours back, a video surfaced showing two Kuki women were shown as stripped, naked and Meitei men touching their private parts. Later on, we came to know that this was in response of a disinformation news spread by the Meitis of few women being raped although no documentary evidence of the same surfaced, no names nothing. While I don t want to share the video I will however share the statement shared by the Kuki-Zo tribal community on that. The print gives a bit more context to what has been going on.

Update, Few hours later : The Print also shared more of a context about six days ago. The reason we saw the video now was that for the last 2.5 months Manipur was in Internet shutdown so those videos got uploaded now. There was huge backlash from the Twitter community and GOI ordered the Manipur Police to issue this Press Release yesterday night or just few hours before with yesterday s time-stamp.

IndianExpress shared an article that does state that while an FIR had been registered immediately no arrests so far and this is when you can see the faces of all the accused. Not one of them tried to hide their face behind a mask or something. So, if the police wanted, they could have easily identified who they are. They know which community the accused belong to, they even know from where they came. If they wanted to, they could have easily used mobile data and triangulation to find the accused and their helpers. So, it does seem to be attempt to whitewash and protect a certain community while letting it prey on the other. Another news that did come in, is because of the furious reaction on Twitter, Youtube has constantly been taking down the video as some people are getting a sort of high more so from the majoritarian community and making lewd remarks. Twitter has been somewhat quick when people are making lewd remarks against the two girl/women. Quite a bit of the above seems like a cover-up. Lastly, apparently GOI has agreed to having a conversation about it in Lok Sabha but without any voting or passing any resolutions as of right now. Would update as an when things change. Update: Smriti Irani, the Child and Development Minister gave the weakest statement possible

As can be noticed, she said sexual assault rather than rape. The women were under police custody for safety when they were whisked away by the mob. No mention of that. She spoke to the Chief Minister who has been publicly known as one of the provocateurs or instigators for the whole thing. The CM had publicly called the Kukus and Nagas as foreigners although both of them claim to be residing for thousands of years and they apparently have documentary evidence of the same . Also not clear who is doing the condemning here. No word of support for the women, no offer of intervention, why is she the Minister of Child and Women Development (CDW) if she can t use harsh words or give support to the women who have gone and going through horrific things Update : CM Biren Singh s Statement after the video surfaced

This tweet is contradictory to the statements made by Mr. Singh couple of months ago. At that point in time, Mr. Singh had said that NIA, State Intelligence Departments etc. were giving him minute to minute report on the ground station. The Police itself has suo-moto (on its own) powers to investigate and apprehend criminals for any crime. In fact, the Police can call for questioning of anybody in any relation to any crime and question them for upto 48 hours before charging them. In fact, many cases have been lodged where innocent persons have been framed or they have served much more in the jail than the crime they are alleged to have been committed. For e.g. just a few days before there was a media report of a boy who has been in jail for 3 years. His alleged crime, stealing mere INR 200/- to feed himself. Court doesn t have time to listen to him yet. And there are millions like him. The quint eloquently shares the tale where it tells how both the State and the Centre have been explicitly complicit in the incidents ravaging Manipur. In fact, what has been shared in the article has been very true as far as greed for land is concerned. Just couple of weeks back there have been a ton of floods emanating from Uttarakhand and others. Just before the flooding began, what was the CM doing can be seen here. Apart from the newspapers I have shared and the online resources, most of the mainstream media has been silent on the above. In fact, they have been silent on the Manipur issue until the said video didn t come into limelight. Just now, in Lok Sabha everybody is present except the Prime Minister and the Home Minister. The PM did say that the law will take its own course, but that s about it. Again no support for the women concerned. Update: CJI (Chief Justice of India) has taken suo-moto cognizance and has warned both the State and Centre to move quickly otherwise they will take the matter in their own hand.

Update: Within 2 hours of the CJI taking suo-moto cognizance, they have arrested one of the main accused Heera Das

The above tells you why the ban on Internet was put in the first place. They wanted to cover it all up. Of all the celebs, only one could find a bit of spine, a bit of backbone to speak about it, all the rest mum

Just imagine, one of the women is around my age while the young one could have been a daughter if I had married on time or a younger sister for sure. If ever I came face to face with them, I just wouldn t be able to look them in the eye. Even their whole whataboutery is built on sham. From their view Kukis are from Burma or Burmese descent. All of which could be easily proved by DNA of all. But let s leave that for a sec. Let s take their own argument that they are Burmese. Their idea of Akhand Bharat stretches all the way to Burma (now called Myanmar). They want all the land but no idea with what to do with the citizens living on it. Even after the video, the whataboutery isn t stopping, that shows how much hatred is there. And not knowing that they too will be victim of the same venom one or the other day Update: Opposition was told there would be a debate on Manipur. The whole day went by, no debate. That s the shamelessness of this Govt. Update 20th July 19:25 Center may act or not act against the perpetrators but they will act against Twitter who showed the crime. Talk about shooting the messenger

We are now in the last stage. In 2014, we were at 6

Just a few days back we came to know about the horrific Train Crash that happened in Odisha (Orissa). There are some things that are known and somethings that can be inferred by observance. Sadly, it seems the incident is going to be covered up . Some of the facts that have not been contested in the public domain are that there were three lines. One loop line on which the Goods Train was standing and there was an up and a down line. So three lines were there. Apparently, the signalling system and the inter-locking system had issues as highlighted by an official about a month back. That letter, thankfully is in the public domain and I have downloaded it as well. It s a letter that goes to 4 pages. The RW is incensed that the letter got leaked and is in public domain. They are blaming everyone and espousing conspiracy theories rather than taking the minister to task. Incidentally, the Minister has three ministries that he currently holds. Ministry of Communication, Ministry of Electronics and Information Technology (MEIT), and Railways Ministry. Each Ministry in itself is important and has revenues of more than 6 lakh crore rupees. How he is able to do justice to all the three ministries is beyond me The other thing is funds both for safety and relaying of tracks has been either not sanctioned or unutilized. In fact, CAG and the Railway Brass had shared how derailments have increased and unfulfilled vacancies but they were given no importance In fact, not talking about safety in the recently held Chintan Shivir (brainstorming session) tells you how much the Govt. is serious about safety. In fact, most of the programme was on high speed rail which is a white elephant. I have shared a whitepaper done by RW in the U.S. that tells how high-speed rail doesn t make economic sense. And that is an economy that is 20 times + the Indian Economy. Even the Chinese are stopping with HSR as it doesn t make economic sense. Incidentally, Air Fares again went up 200% yesterday. Somebody shared in the region of 20k + for an Air ticket from their place to Bangalore Coming back to the story itself. the Goods Train was on the loopline. Some say it was a little bit on the outer, some say otherwise, but it is established that it was on the loopline. This is standard behavior on and around Railway Stations around the world. Whether it was in the Inner or Outer doesn t make much of a difference with what happened next. The first train that collided with the goods train was the 12864 (SMVB-HWH) Yashwantpur Howrah Express and got derailed on to the next track where from the opposite direction 12841 (Shalimar- Bangalore) Coramandel Express was coming. Now they have said that around 300 people have died and that seems to be part of the cover-up. Both the trains are long trains, having between 23 odd coaches each. Even if you have reserved tickets you have 80 odd people in a coach and usually in most of these trains, it is at least double of that. Lot of money goes to TC and then above (Corruption). The Railway fares have gone up enormously but that s a question for perhaps another time . So at the very least, we could be looking at more than 1000 people having died. The numbers are being under-reported so that nobody has to take responsibility. The Railways itself has told that it is unable to identify 80% of the people who have died. This means that 80% were unreserved ticket holders or a majority of them. There have been disturbing images as how bodies have been flung over on tractors and whatnot to be either buried or cremated without a thought. We are in peak summer season so bodies will start to rot within 24-48 hours No arrangements made to cool the bodies and take some information and identifying marks or whatever. The whole thing being done in a very callous manner, not giving dignity to even those who have died for no fault of their own. The dissent note also tells that a cover-up is also in the picture. Apparently, India doesn t have nor does it feel to have a need for something like the NTSB that the U.S. used when it hauled both the plane manufacturer (Boeing) and the FAA when the 737 Max went down due to improper data collection and sharing of data with pilots. And with no accountability being fixed to Minister or any of the senior staff, a small junior staff person may be fired. Perhaps the same official that actually told them about the signal failures almost 3 months back There were and are also some reports that some jugaadu /temporary fixes were applied to signalling and inter-locking just before this incident happened. I do not know nor confirm one way or the other if the above happened. I can however point out that if such a thing happened, then usually a traffic block is announced and all traffic on those lines are stopped. This has been the thing I know for decades. Traveling between Mumbai and Pune multiple times over the years am aware about traffic block. If some repair work was going on and it wasn t able to complete the work within the time-frame then that may well have contributed to the accident. There is also a bit muddying of the waters where it is being said that one of the trains was 4 hours late, which one is conflicting stories. On top of the whole thing, they have put the case to be investigated by CBI and hinting at sabotage. They also tried to paint a religious structure as mosque, later turned out to be a temple. The RW says done by Muslims as it was Friday not taking into account as shared before that most Railway maintenance works are usually done between Friday Monday. This is a practice followed not just in India but world over. There has been also move over a decade to remove wooden sleepers and have concrete sleepers. Unlike the wooden ones they do not expand and contract as much and their life is much more longer than the wooden ones. Funds had been marked (although lower than last few years) but not yet spent. As we know in case of any accident, it is when all the holes in cheese line up it happens. Fukushima is a great example of that, no sea wall even though Japan is no stranger to Tsunamis. External power at the same level as the plant. (10 meters above sea-level), no training for cascading failures scenarios which is what happened. The Days mini-series shares some but not all the faults that happened at Fukushima and the Govt. response to it. There is a difference though, the Japanese Prime Minister resigned on moral grounds. Here, nor the PM, nor the Minister would be resigning on moral grounds or otherwise :(. Zero accountability and that was partly a natural disaster, here it s man-made. In fact, both the Minister and the Prime Minister arrived with their entourages, did a PR blitzkrieg showing how concerned they are. Within 50 hours, the lines were cleared. The part-time Railway Minister shared that he knows the root cause and then few hours later has given the case to CBI. All are saying, wait for the inquiry report. To date, none of the accidents even in this Govt. has produced an investigation report. And even if it did, I am sure it will whitewash as it did in case of Adani as I had shared before in the previous blog post. Incidentally, it is reported that Adani paid off some of its debt, but when questioned as to where they got the money, complete silence on that part :(. As can be seen cover-up after cover-up FWIW, the Coramandel Express is known as the Migrant train so has a huge number of passengers, the other one which was collided with is known as sick train as huge number of cancer patients use it to travel to Chennai and come back

Demonetization 2.0 Few days back, India announced demonetization 2.0. Surprised, don t be. Apparently, INR 2k/- is being used for corruption and Mr. Modi is unhappy about it. He actually didn t like the INR 2k/- note but was told that it was needed, who told him we are unaware to date. At that time the RBI Governor was Mr. Urjit Patel who didn t say about INR 2k/- he had said that INR 1k/- note redesigned would come in the market. That has yet to happen. What has happened is that just like INR 500/- and INR 1k/- note is concerned, RBI will no longer honor the INR 2k/- note. Obviously, this has made our neighbors angry, namely Nepal, Sri Lanka, Bhutan etc. who do some trading with us. 2 Deccan herald columns share the limelight on it. Apparently, India wants to be the world s currency reserve but doesn t want to play by the rules for everyone else. It was pointed out that both the U.S. and Singapore had retired their currencies but they will honor that promise even today. The Singapore example being a bit closer (as it s in Asia) is perhaps a bit more relevant than the U.S. one. Singapore retired the SGD $10,000 as of 2014 but even in 2022, it remains as legal tender. They also retired the SGD $1,000 in 2020 but still remains legal tender.

So let s have a fictitious example to illustrate what is meant by what Singapore has done. Let s say I go to Singapore, rent a flat, and find a $1000 note in that house somewhere. Both practically and theoretically, I could go down to any of the banks, get the amount transferred to my wallet, bank account etc. and nobody will question. Because they have promised the same. Interestingly, the Singapore Dollar has been pretty resilient against the USD for quite a number of years vis-a-vis other Asian currencies. Most of the INR 2k/- notes were also found and exchanged in Gujarat in just a few days (The PM and HM s state.). I am sure you are looking into the mental gymnastics that the RW indulge in :(. What is sadder that most of the people who try to defend can t make sense one way or the other and start to name-call and get personal as they have nothing else

Disability questions dropped in NHFS-6 Just came to know today that in the upcoming National Family Health Survey-6 disability questions are being dropped. Why is this important. To put it simply, if you don t have numbers, you won t and can t make policies for them. India is one of the worst countries to live if you are disabled. The easiest way to share to draw attention is most Railway platforms are not at level with people. Just as Mick Lynch shares in the UK, the same is pretty much true for India too. Meanwhile in Europe, they do make an effort to be level so even disabled people have some dignity. If your public transport is sorted, then people would want much more and you will be obligated to provide for them as they are citizens. Here, we have had many reports of women being sexually molested when being transferred from platform to coach irrespective of their age or whatnot The main takeaway is if you do not have their voice, you won t make policies for them. They won t go away but you will make life hell for them. One thing to keep in mind that most people assume that most people are disabled from birth. This may or may not be true. For e.g. in the above triple Railways accidents, there are bound to be disabled people or newly disabled people who were healthy before the accident. The most common accident is road accidents, some involving pedestrians and vehicles or both, the easiest is Ministry of Road Transport data that says 4,00,000 people sustained injuries in 2021 alone in road mishaps. And this is in a country where even accidents are highly under-reported, for more than one reason. The biggest reason especially in 2 and 4 wheeler is the increased premium they would have to pay if in an accident, so they usually compromise with the other and pay off the Traffic Inspector. Sadly, I haven t read a new book, although there are a few books I m looking forward to have. People living in India and neighbors please be careful as more heat waves are expected. Till later.

Some time ago, on an early Friday afternoon our internet connection died. After a reasonable time had passed we called the customer service, they told us that they would look into it and then call us back. On Friday evening we had not heard from them, and I was starting to get worried. At the time in the evening when I would have been relaxing online I grabbed the first Victorian sewing-related book I found on my hard disk and started to read it. For the record, it wasn t actually Victorian, it was Margaret J. Blair. System of Sewing and Garment Drafting. from 1904, but I also had available for comparison the earlier and smaller Margaret Blair. System of Garment Drafting. from 1897. Anyway, this book had a system to draft a pair of combinations (chemise top + drawers); and months ago I had already tried to draft a pair from another system, but they didn t really fit and they were dropped low on the priority list, so on a whim I decided to try and draft them again with this new-to-me system. Around 23:00 in the night the pattern was ready, and I realized that my SO had gone to sleep without waiting for me, as I looked too busy to be interrupted. The next few days were quite stressful (we didn t get our internet back until Wednesday) and while I couldn t work at my day job I didn t sew as much as I could have done, but by the end of the week I had an almost complete mockup from an old sheet, and could see that it wasn t great, but it was a good start. One reason why the mockup took a whole week is that of course I started to sew by machine, but then I wanted flat-felled seams, and felling them by hand is so much neater, isn t it? And let me just say, I m grateful for the fact that I don t depend on streaming services for media, but I have a healthy mix of DVDs and stuff I had already temporary downloaded to watch later, because handsewing and being stressed out without watching something is not really great. Anyway, the mockup was a bit short on the crotch, but by the time I could try it on and be sure I was invested enough in it that I decided to work around the issue by inserting a strip of lace around the waist. And then I went back to the pattern to fix it properly, and found out that I had drafted the back of the drawers completely wrong, making a seam shorter rather than longer as it should have been. ooops. I fixed the pattern, and then decided that YOLO and cut the new version directly on some lightweight linen fabric I had originally planned to use in this project. The result is still not perfect, but good enough, and I finished it with a very restrained amount of lace at the neckline and hems, wore it one day when the weather was warm (loved the linen on the skin) and it s ready to be worn again when the weather will be back to being warm (hopefully not too soon). The last problem was taking pictures of this underwear in a way that preserves the decency (and it even had to be outdoors, for the light!). This was solved by wearing leggings and a matched long sleeved shirt under the combinations, and then promptly forgetting everything about decency and, well, you can see what happened. The pattern is, as usual, published on my pattern website as #FreeSoftWear. And then, I started thinking about knits. In the late Victorian and Edwardian eras knit underwear was a thing, also thanks to the influence of various aspects of the rational dress movement; reformers such as Gustav J ger advocated for wool underwear, but mail order catalogues from the era such as https://archive.org/details/cataloguefallwin00macy (starting from page 67) have listings for both cotton and wool ones. From what I could find, back then they would have been either handknit at home or made to shape on industrial knitting machines; patterns for the former are available online, but the latter would probably require a knitting machine that I don t currently¹ have. However, this is underwear that is not going to be seen by anybody², and I believe that by using flat knit fabric one can get a decent functional approximation. In The Stash I have a few meters of a worked cotton jersey with a pretty comfy feel, and to make a long story short: this happened. I suspect that the linen one will get worn a lot this summer (linen on the skin. nothing else need to be said), while the cotton one will be stored away for winter. And then maybe I may make a couple more, if I find out that I m using it enough.

Review: A Half-Built Garden, by Ruthanna Emrys

Format:	Kindle
Pages:	340

The climate apocalypse has happened. Humans woke up to the danger, but a little bit too late. Over one billion people died. But the world on the other side of that apocalypse is not entirely grim. The corporations responsible for so much of the damage have been pushed out of society and isolated on their independent "aislands," traded with only grudgingly for the few commodities the rest of the world has not yet learned how to manufacture without them. Traditional governments have largely collapsed, although they cling to increasingly irrelevant trappings of power. In their place arose the watershed networks: a new way of living with both nature and other humans, built around a mix of anarchic consensus and direct democracy, with conservation and stewardship of the natural environment at its core. Therefore, when the aliens arrive near Bear Island on the Potomac River, they're not detected by powerful telescopes and met by military jets. Instead, their waste sets off water sensors, and they're met by the two women on call for alert duty, carrying a nursing infant and backed by the real-time discussion and consensus technology of the watershed's dandelion network. (Emrys is far from the first person to name something a "dandelion network," so be aware that the usage in this book seems unrelated to the charities or blockchain network.) This is a first contact novel, but it's one that skips over the typical focus of the subgenre. The alien Ringers are completely fluent in English down to subtle nuance of emotion and connotation (supposedly due to observation of our radio and TV signals), have translation devices, and in some cases can make our speech sounds directly. Despite significantly different body shapes, they are immediately comprehensible; differences are limited mostly to family structure, reproduction, and social norms. This is Star Trek first contact, not the type more typical of written science fiction. That feels unrealistic, but it's also obviously an authorial choice to jump directly to the part of the story that Emrys wants to write. The Ringers have come to save humanity. In their experience, technological civilization is inherently incompatible with planets. Technology will destroy the planet, and the planet will in turn destroy the species unless they can escape. They have reached other worlds multiple times before, only to discover that they were too late and everyone is already dead. This is the first time they've arrived in time, and they're eager to help humanity off its dying planet to join them in the Dyson sphere of space habitats they are constructing. Planets, to them, are a nest and a launching pad, something to eventually abandon and break down for spare parts. The small, unexpected wrinkle is that Judy, Carol, and the rest of their watershed network are not interested in leaving Earth. They've finally figured out the most critical pieces of environmental balance. Earth is going to get hotter for a while, but the trend is slowing. What they're doing is working. Humanity would benefit greatly from Ringer technology and the expertise that comes from managing closed habitat ecosystems, but they don't need rescuing. This goes over about as well as a toddler saying that playing in the road is perfectly safe. This is a fantastic hook for a science fiction novel. It does exactly what a great science fiction premise should do: takes current concerns (environmentalism, space boosterism, the debatable primacy of humans as a species, the appropriate role of space colonization, the tension between hopefulness and doomcasting about climate change) and uses the freedom of science fiction to twist them around and come at them from an entirely different angle. The design of the aliens is excellent for this purpose. The Ringers are not one alien species; they are two, evolved on different planets in the same system. The plains dwellers developed space flight first and went to meet the tree dwellers, and while their relationship is not entirely without hierarchy (the plains dwellers clearly lead on most matters), it's extensively symbiotic. They now form mixed families of both species, and have a rich cultural history of stories about first contact, interspecies conflicts and cooperation, and all the perils and misunderstandings that they successfully navigated. It makes their approach to humanity more believable to know that they have done first contact before and are building on a model. Their concern for humanity is credibly sincere. The joining of two species was wildly successful for them and they truly want to add a third. The politics on the human side are satisfyingly complicated. The watershed network may have made first contact, but the US government (in the form of NASA) is close behind, attempting to lean on its widely ignored formal power. The corporations are farther away and therefore slower to arrive, but the alien visitors have a damaged ship and need space to construct a subspace beacon and Asterion is happy to offer a site on one of its New Zealand islands. The corporate representatives are salivating at the chance to escape Earth and its environmental regulation for uncontrolled space construction and a new market of trillions of Ringers. NASA's attitude is more measured, but their representative is easily persuaded that the true future of humanity is in space. The work the watershed networks are doing is difficult, uncertain, and involves a lot of sacrifice, particularly for corporate consumer lifestyles. With such an attractive alien offer on the table, why stay and work so hard for an uncertain future? Maybe the Ringers are right. And then the dandelion networks that the watersheds use as the core of their governance and decision-making system all crash. The setup was great; I was completely invested. The execution was more mixed. There are some things I really liked, some things that I thought were a bit too easy or predictable, and several places where I wish Emrys had dug deeper and provided more detail. I thought the last third of the book fizzled a little, although some of the secondary characters Emrys introduces are delightful and carry the momentum of the story when the politics feel a bit lacking. If you tried to form a mental image of ecofeminist political science fiction with 1970s utopian sensibilities, but updated for the concerns of the 2020s, you would probably come very close to the politics of the watershed networks. There are considerably more breastfeedings and diaper changes than the average SF novel. Two of the primary characters are transgender, but with very different experiences with transition. Pronoun pins are an ubiquitous article of clothing. One of the characters has a prosthetic limb. Another character who becomes important later in the story codes as autistic. None of this felt gratuitous; the characters do come across as obsessed with gender, but in a way that I found believable. The human diversity is well-integrated with the story, shapes the characters, creates practical challenges, and has subtle (and sometimes not so subtle) political ramifications. But, and I say this with love because while these are not quite my people they're closely adjacent to my people, the social politics of this book are a very specific type of white feminist collaborative utopianism. When religion makes an appearance, I was completely unsurprised to find that several of the characters are Jewish. Race never makes a significant appearance at all. It's the sort of book where the throw-away references to other important watershed networks includes African ones, and the characters would doubtless try to be sensitive to racial issues if they came up, but somehow they never do. (If you're wondering if there's polyamory in this book, yes, yes there is, and also I suspect you know exactly what culture I'm talking about.) This is not intended as a criticism, just more of a calibration. All science fiction publishing houses could focus only on this specific political perspective for a year and the results would still be dwarfed by the towering accumulated pile of thoughtless paeans to capitalism. Ecofeminism has a long history in the genre but still doesn't show up in that many books, and we're far from exhausting the space of possibilities for what a consensus-based politics could look like with extensive computer support. But this book has a highly specific point of view, enough so that there won't be many thought-provoking surprises if you're already familiar with this school of political thought. The politics are also very earnest in a way that I admit provoked a bit of eyerolling. Emrys pushes all of the political conflict into the contrasts between the human factions, but I would have liked more internal disagreement within the watershed networks over principles rather than tactics. The degree of ideological agreement within the watershed group felt a bit unrealistic. But, that said, at least politics truly matters and the characters wrestle directly with some tricky questions. I would have liked to see more specifics about the dandelion network and the exact mechanics of the consensus decision process, since that sort of thing is my jam, but we at least get more details than are typical in science fiction. I'll take this over cynical libertarianism any day. Gender plays a huge role in this story, enough so that you should avoid this book if you're not interested in exploring gender conceptions. One of the two alien races is matriarchal and places immense social value on motherhood, and it's culturally expected to bring your children with you for any important negotiation. The watersheds actively embrace this, or at worst find it comfortable to use for their advantage, despite a few hints that the matriarchy of the plains aliens may have a very serious long-term demographic problem. In an interesting twist, it's the mostly-evil corporations that truly challenge gender roles, albeit by turning it into an opportunity to sell more clothing. The Asterion corporate representatives are, as expected, mostly the villains of the plot: flashy, hierarchical, consumerist, greedy, and exploitative. But gender among the corporations is purely a matter of public performance, one of a set of roles that you can put on and off as you choose and signal with clothing. They mostly use neopronouns, change pronouns as frequently as their clothing, and treat any question of body plumbing as intensely private. By comparison, the very 2020 attitudes of the watersheds towards gender felt oddly conservative and essentialist, and the main characters get flustered and annoyed by the ever-fluid corporate gender presentation. I wish Emrys had done more with this. As you can tell, I have a lot of thoughts and a lot of quibbles. Another example: computer security plays an important role in the plot and was sufficiently well-described that I have serious questions about the system architecture and security model of the dandelion networks. But, as with decision-making and gender, the more important takeaway is that Emrys takes enough risks and describes enough interesting ideas that there's a lot of meat here to argue with. That, more than getting everything right, is what a good science fiction novel should do. A Half-Built Garden is written from a very specific political stance that may make it a bit predictable or off-putting, and I thought the tail end of the book had some plot and resolution problems, but arguing with it was one of the more intellectually satisfying science fiction reading experiences I've had recently. You have to be in the right mood, but recommended for when you are. Rating: 7 out of 10
