It s not very often that I watch a movie anymore. It s been a few years since I ve actually purchased one (normally I see them from Netflix). But yesterday I saw one that may change that. The Lives of Others is an incredible film set in the former East Germany (GDR/DDR) mostly in 1984. The authenticity of it is incredible and so is the story. It s subtitled, but if you re an American wary of subtitled European films, don t be wary of this one. It is easy to watch and worth every minute. The story revolves around the Stasi, the GDR Ministry for State Security ( secret police ). It is an incredible picture of what living in a police state was like, and how many of the informants were victims of the regime too. My breath caught near the beginning of the film, showing the inside of a Stasi building. A prisoner was being interrogated for helping someone attempt to escape to the west. But the reason my breath caught was this incredible feeling of I was there . Last year, Terah and I were in Leipzig and visited the Stasi museum there, Museum in der Runden Ecke . I always have an incredible sense of history when being in a preserved place, and this building was literally the Stasi headquarters for Leipzig. Much of it was preserved intact, and seeing it in the film brought home even more vividly the terrible things that happened in that building, and others like it, not so very long ago. We watched the special features on the Blu-Ray disc, and one of them was an interview with director Florian Henckel von Donnersmarck. He described how he spent a lot of time interviewing both victims of the Stasi, as well as ex-Stasi officers. One of the most disturbing things to me was his almost offhand comment that most of the former Stasi officers still had some pride in performing their jobs well. Even now, freed of the state s ideology, they were proud of the work they did which could be put most charitably as ruining people s lives. What leads a person to view life that way? How can we try to make sure it doesn t happen again elsewhere? I am happy to say that most of us have never experienced anything like the Stasi. And yet, small reflections of that mindset can be seen almost everywhere. Societies at wartime or feeling under threat, even Western democracies, can drum up those feelings. In the USA, for instance, the McCarthyism era saw people s careers ruined for alleged anti-state behavior. Contemporary examples include the indefinite detention (I hate that word; shouldn t we say imprisonment ?) of terrorism suspects at Guantanamo Bay, and the terrible treatment of Bradley Manning, who revealed some true but embarrassing things about the US military which really needed to be revealed. Even tobacco farmers and companies are selling a product they know ruins lives, but somehow keep doing it. And there are still members of the public that try to make life difficult for people that don t think like they do. From organizing campaigns of telephone harassment of colleges that don t perform the American national anthem before sporting events, to tossing about the term un-American (a loaded McCarthyist one, which many may not even be aware) at an inflated rate, we are not immune from attempts at forcing conformity or silence in others, and blind loyalty to state. I am never in a particularly celebratory mood on July 4, the biggest day for American boasting, faux patriotism, militarism, and general flag-waving. We do have a lot to be proud of and thankful for, but it seems that we celebrate all the wrong things on July 4, and see it as an occasion to proclaim American exceptionalism rather than as one to see how far we ve come and bolster hope for how far we can, and should, yet go. No, I don t think that the land of the free ought to have operated secret prisons in Europe (nor the Europeans to have been complicit in it), or that the American military was defending our freedom 100% of the time they were deployed, or that it is right for governments to mandate daily recitation of an untrue document (the pledge of allegiance) in schools. And yet, I am mindful that I have a lot to be thankful for stability, lack of much internal violent conflict, etc. And this particular day I am happy that a post like this is not something that gets the attention of some government agency and mostly that I will have a handful of angry emails to delete.

I was given this Sheevaplug. The idea with plug computers is they look like just a wall wart, but are a whole computer. Ideally, a FreedomBox. The wall wart computer concept doesn't entirely work for me because first, I don't like socket blocking wall warts, and secondly, I'm living in the island of Offgridistan with its weird 12 volt wall sockets. Solution was to convert it to be USB powered. This is easy because the Sheevaplug's built-in power supply runs it at 5 volts.

my Sheevaplug, powered by my laptop, with serial console also hooked up to show boot.

The USB power cable was conveniently routed in through a clip that holds the power socket in place. Bonus: The clip lets the cable be pushed in, but not pulled out, which avoids strain on the connection.
Then it's just a matter of connecting the obvious wires. (I couldn't find a 4 pin connector on short notice so I reluctantly cut the short cord from the AC power supply.) I'd probably not want to fly with the result (want to install a proper USB socket for power to avoid the dangling exposed wire effect), but it's otherwise pretty perfect. I've replaced my nslu2 wifi/dialup/cache/mpd box with the Sheevaplug, and the massively increased memory and speed, at nearly the same power, is a nice improvement.

I did run into two weird issues. I have to use a USB stick for storage, since both SDHC cards I tried, a 16 gb Transcend and a 1 gb no-name had lots of IO errors (error -110). I don't seem to be the first to encounter that, but there is not a sure workaround, although recompiling the kernel wirth high speed SD disabled might fix it. Also, u-boot refused to boot from my USB stick when I used one USB hub; with a different hub it worked ok.

So we're just over 2 weeks away from our next set of local elections in the UK (May 5th), and alongside those elections we're also being asked about switching to a new voting system for future elections. For a long time we've used the simple First Past The Post (FPTP) system here, but now we have the possbility of moving to Alternative Vote (AV) instead. First Past The Post FPTP is simple to understand - the person who receives more votes than any single other person wins. But that simplicity is the only good thing, and there are many problems with it. It's unfair: in an election with 10 candidate, it's possible for a winner to have just 11% of the vote, even in the case where the other 89% of voters would consider them to be the worst option. It's also very susceptible to tactical voting, leading to nasty tactics in parties' election literature like claiming "party foo cannot win here, so don't waste your vote on them - vote for us instead!". See this Wikipedia article for more background. Alternative Vote AV is slightly more complicated. Instead of just placing a mark against their single preferred candidate, voters are able to rank as many of the candidates as they like. In the case that there is not a clear winner with more than 50% of the votes from the initial count, the lowest-ranked candidate is eliminated and second-choice votes from their supporters are counted and re-distributed for the other candidates. Iterate this process until one candidate gets more than 50% of the total votes. By re-calculating the votes this way, supporters of less popular candidates / parties should no longer feel the pressure to vote tactically and a more accurate picture of voter intention should emerge. The downsides? AV will tend to lead to slower, more expensive counting due to the potential for several rounds. It's still not real proportional voting, but it's better than FPTP in this regard. Again, Wikipedia has a good article about this subject. Other options? I'd be much happier to see discussion / trials of other voting systems. For example, Debian uses a variation on Condorcet called Cloneproof Schwartz Sequential Dropping which is an excellent system for fair voting, but it's very difficult to explain and counting votes is comparatively very expensive. It's bad enough getting ostensibly-intelligent Debian developers to understand this system; extending this to a national election would be impossible in my opinion. It's also not an option on the ballot here... :-) Politicians spreading lies I know this won't come as a major shock for a nationwide referendum, but there's a lot of campaigning going on. And, in the best traditions of political campaigning, there's a huge amount of bullshit being spread. The worst is coming from the "No to AV" campaign, as far as I can see. Without many positive things to claim, various members of the Conservative party (current government, with most to fear from a change of voting system, of course) are spouting outright lies and sowing FUD in all directions:

1. Claiming that AV will cost 250 million, most of which would be for the cost of electronic voting machines. Except... there's no evidence that these would be needed, nor are there any plans to use them.
2. Continuing on, highlighting the alleged "extra costs" of AV: campaign poster FUD saying that we need to choose between cardiac facilities for babies and AV, or between equipment for our soldiers and AV. Except... there's no evidence that costs will be that high, nor that we have to make such binary choices.
3. Claims from senior Conservative figures that changing to AV would mean more votes and legitimacy for extremists like the British National Party. Except... there is no evidence that AV will boost minority extremist parties. The BNP themselves are urging their supporters to vote against AV. Finally, if these parties have a high enough proportion of votes that they should be getting seats in parliament then they should have those seats - this is one of the tenets of democracy. Why should we be choosing a voting system to deliberately disenfranchise people?
4. Finally, even David Cameron is at it: "too much of the debate about the alternative vote (AV) had so far been dominated by 'scientific' evaluation of the two systems' merits. But for me, politics shouldn't be some mind-bending exercise. It's about what you feel in your gut - about the values you hold dear and the beliefs you instinctively have. And I just feel it, in my gut, that AV is wrong." Well, it's nice that our Prime Minister wants to ignore all the scientific evidence and go with his gut feeling. After all, why would we want to think about choices like this?

Don't swallow the bullshit If you're eligible to vote in the UK, please ignore the bollocks. Make up your own mind how to vote in this referendum, by looking at the facts. I've done that and I'll be voting in favour of switching to AV.

I ve now had a Sony Ericsson Xperia X10 for almost two months (here is a link for my first review) [1]. This is a phone that people seem to really dislike because the battery life is poor and Sony doesn t allow replacing the kernel. I m happy with mine, happy enough that after buying one for my wife and trying it out I bought one for myself. I knew about it s problems in advance and wanted a relatively cheap phone with a large high resolution screen, and the Xperia X10 was the best match for my criteria.ChargingThere has been a recent trend towards using USB for charging devices. Sony provides a tiny wall-wart PSU which has a USB socket and a short (1m) USB cable that can be used to charge the phone from it s PSU or from a PC. The size is really convenient, as the phone has a short battery life I ll probably want to take the PSU to more places than I would for other phones I ve owned.The short USB cable saves weight and tangle when travelling, but can be inconvenient. I m currently working on the phone while it s plugged into my laptop, that works well and I can make calls while it s connected. If the phone was connected to a USB port on a tower computer that was on the ground then the cable could be too short to make a call, if it was charging on a power point near the floor then I wouldn t even be able to use the computer functionality let alone make calls without kneeling. My Viewty has a 175cm charging cable which alleviates these problems. I ve got a 50cm USB extension cable that I use for charging my phone while I m in bed that is just long enough to allow me to check my email without getting out of bed!The socket for connecting the USB cable is protected by a plastic lid that is connected by a strip of rubber. For a socket that will be used at least twice a day this isn t a good mechanical design. The plastic slide on the LG U990 Viewty seems like a much better design.As an aside it s a pity that they aren t designing cars with USB charging sockets built in. Some new cars have a socket for one USB flash drive to be attached to the radio, but really they need at least one USB charging port per seat. It would also be nice if they made power points with USB charging sockets built in, I d buy a few of those if they made them.Preserving the BatteryI ve been running Juice Defender to reduce the battery use, at the moment it is claiming to have extended battery life by 69%. That combined with turning off things that aren t needed (such as WiFi) has made the phone reasonably usable. I can survive more than 12 hours during which I use the phone a lot without charging it.XperiaX10.net has an interesting review of replacement batteries [5]. I m not going to buy them because the largest battery requires a replacement back case which prevents using an external case to prevent damage and the smaller one doesn t provide enough of a benefit and the design of the phone makes it difficult to change batteries so carrying a spare battery isn t a good option.Cursor Control KeysThe HP/Compaq iPaQs that I own from ~10 years ago have a single button that can be moved up/down/left/right to act as a cursor, it can also be pressed inwards to act as an ENTER key (or whatever the application might want for a fifth function). Having some sort of hardware cursor control is really handy, I often end up deleting several characters when I want to replace one because getting the cursor onto the desired character is too difficult.Adding more hardware keys would require making the phone bigger, but that would be fine by me. As described in my previous post about phone cameras I d like to have a phone that s thicker to have a better camera with a greater focal distance for a larger lens [2].Core Phone FunctionalityI really miss having separate green and red buttons for making/answering calls and for rejecting/ending calls.A really common operation is to call back the last person who called. To do this on my LG U990 Viewty I press the green button twice on my home screen which took less than a second. On the Xperia this involves selecting the phone icon from the home screen, then the call log icon, then the call that is desired, then the Call user line. That is four presses in different parts of the screen compared to pressing the same hardware button twice. I m investigating dialer applets right now, the Dialler One applet has a good interface for calling people who have called or been called recently but it still requires two presses on different parts of the screen. With my old Viewty I could call back the last person by feel without even looking at the phone!In the last 6 years the standard functionality of phones has been to include multiple profiles for noises. My Viewty has profiles named Normal , Silent , Vibrate only , Outdoor , Headset (automatically selected when a headset is connected), and three customised ones. The Xperia has only one setting, and that is three icon presses away from the home screen. It does allow changing the volume by hardware switches on the side which includes going to vibrate-only and silent mode. While this is useful, it s not the best way that two precious hardware keys could be used. It also doesn t allow control over all the different notifications, I d like to be able to activate a noise profile and have every application respond to it in an appropriate manner. This is a deficiency in Android 2.1 not in the phone itself.In many ways this phone has the worst phone functionality of any mobile phone I ve ever owned, I think that this is more the fault of the Android designers than Sony Ericsson.Android UpdatesSony had previously claimed that they wouldn t support Android later than 2.1. Now Sony has announced that they will support Gingerbread Android 2.3 [3]. So one of the major complaints about the Xperia will soon be addressed.TetheringThe build of Android that the Xperia runs at the moment doesn t support Wifi tethering. I m currently using with Easy Tether for USB tethering [4]. It s not free software and requires it s own code to run as root on your Linux system that is being tethered (which is easily locked down with SE Linux), but it basically works. The down-side with Easy Tether is that it proxies all the connections so you can t run traceroute etc and in the free version you can t use UDP.K9 MailK9 Mail fixes some of the problems in the default Android email program that I described in my previous post. It allows selection of SSL with a default port of 993 for IMAPs. It uses mail.example.com as the mail server address for an email address of user@example.com (so I ll add a mail CNAME to the domains I run). When I connected initially it told me that the SSL key was not signed by a CA and asked if I wanted to save it or reject it this is the correct and desired functionality. It also correctly parses URLs from the email (or at least has fixed the bug that I discovered in the default email app).One problem I ve found with K9 is that it seems to timeout on large folders. This is probably partly the fault of Virgin Mobile being slow for IP access, but I wonder whether K9 doesn t pipeline IMAP commands as Virgin can do bulk transfer at reasonable speeds (80KB/s) and it mainly fails on latency (900ms being typical). The result is that a folder with more than 500 messages that need to be copied to the phone will never get synchronised. When I started reading mail on my phone I had to move mail from some of the bigger folders into other folders to avoid timeouts. As an aside the amount of time I ve saved by reading email on the go has already paid for the phone.MediascapeThe Sony Mediascape software is used for categorising photos. One function of this is to assign names to photos, the names come from the contact list so if you photograph someone who you can t phone then you need to add a contact list entry for them. This also means that you couldn t conveniently add names to non-humans, I guess I could have added a contact list entry Mr Crash Dump for photos of system crash logs. But a bigger problem is that it decides what is a picture of a person, a picture of someone who is not centered in the photo or a profile picture can be regarded as not a photo of a person and therefore not subject to being associated with a contact list. Finally when selecting a name for a picture it displays the entire contacts list in a small font instead of displaying favorites, I have the phone numbers of many clients in my contacts list who I will never photograph Mediascape just isn t much good. If I feel the need to do something serious in this regard I ll search the app store for something free that s better.ProtectionFor $15 each I bought one grey and one clear Gel Case from J2K. This case covers the sides and back of the phone with a firm rubber layer that will hopefully allow it to bounce rather than break. It also extends slightly higher than the screen which should stop the screen being scratched if the phone is left face-down on a hard surface on the vibrate setting.One problem with the Gel Case is that by it s design it has to cover the buttons on the sides, due to a design or manufacturing problem the clear case that my wife uses can press slightly on the shutter button which disables the three main buttons on the front. So when the menu or back button stops working she has to slightly move the Gel Case out from the side. I m thinking of just cutting out a section of the Gel Case there, that will make it difficult to press the shutter button, but you can use the touch screen to take photos and there doesn t seem to be any other use for the shutter button so this shouldn t be a problem. The clear and grey cases have different designs, the grey one has a hole over the raised Sony logo which makes it fit a little better as well as not having the shutter problem, so it seems to be a later design I don t know whether all clear cases have the same problem but I recommend that someone who only has one Xperia X10 get the grey case just in case.Web BrowsingI m experimenting with using my own web proxy to compress the data sent to the phone. Unfortunately the Android settings for a web proxy only apply to the main web browser, not to all the other applications that use web services. Also the built-in web browser requires pressing the settings hardware button followed by at least two touch-screen presses to change between windows or close a window and it doesn t seem to support making the short-press action be to open a link in a new window. So I will have to find another web browser to use.Bandwidth UseThe 3G Watchdog applet is really good for tracking the data transfer and optionally cutting off 3G access before the quota is exceeded. Unfortunately Virgin has already sent me a bill with $234 in extra charges for bandwidth use because I used 1.6G instead of my 1.5G quota. A Virgin representative had told me over the phone that the billing period would be based on the end of the month, so while every calendar month has had less than 1.5G used because I used more than average in the end of March and the start of April that counts as excess data in the 14th March to 13th April period.I m going to appeal this to the Telecommunications Industry Ombudsman, I don t think that it s reasonable that I should be billed almost 7* the normal bill for exceeding the quota by 7.4% based on following the instructions of a Virgin employee. While I could have read the previous bill that they sent me to discover the end of billing period dates, I don t think that I should be expected to distrust everything that a Virgin employee says. If they billed me an extra $20 then I d just pay it, but $234 is unreasonable.ConclusionSince using the phone I ve found significant benefits in web browsing and reading email with the major limitation being the small screen (relative to a Netbook or Laptop). So if I was to buy another phone I would probably consider a Dell Streak which seems to be the largest Android phone on the market at the moment.Given the amount of use that I ve got I would be happy to spend more money and therefore consider a more expensive phone. But I don t regret the decision to save money by getting an Xperia X10.Finally when a telco tries to stick me with a $234 excess charge it really detracts from the value of having a phone contract. If I end up having to pay that then it s half the value of a smart-phone lost in one telco scam. This is enough to make a contract with Virgin a bad option, after this contract expires I may use VOIP and a pre-paid SIM from Telstra NextG if their network is still the best. Another possibility is to just use a small tablet and skip having a mobile phone, email and Jabber plus SMS from the people who lack net access will probably do.

This year we had very little snow again. Although winter started (too) early (first snow on October 16th) we topped out at little over 50cm in Au (in December). In a normal winter we should have 1m at least temporarily, and 2m is not a rare. Temperatures were high, too. I was usually wearing a layer less than normally. All this had me riding in Dam ls most of time, Diedamskopf only saw me in December, since they have little artificial snow, and natural one was missing. Summer temperatures (20 C) at start of April cut the season very short. My last snow day was on April 3rd. On the upside I did not hurt myself this year (knock, knock) and the weather was good often.

Reading Scott's recent announcement on his move to Google was both surprising and a pleasure. Surprising, because it'll take time to stop associating his name to Ubuntu, Canonical, and the nice experiences I had while I worked with them. A pleasure, because his blog post was full of reminiscences of the very early days of a project that ended up being way more successful in just a few years than probably anyone in the Oxford conference could imagine. Scott, best of luck for this new adventure! Scott's write-up includes a sentence that made me remember I had been wanting to write a blog post related to all of this, but was pending Mark Shuttleworth's permission for posting:

Ok, Mark wasn t really a Nigerian 419 scammer, but some people did discard his e-mail as spam! Scott James Remnant

Many know the story of how I ended not being part of the Super-Secret-Debian-Startup Scott mentions. I even wrote about it in a blog post, 3 years ago:

[...] nothing beats the next email which sat for some dramatic 6 months in my messy inbox until I found out in the worst of the possible scenarios. Let's go back to late February, 2004, when I had no job, and I didn't have a clue on what to do with my life.

I'm hiring a team of debian developers to work full time on a new
distribution based on Debian. We're making internationalisation a prime
focus, together with Python and regular release management. I've discussed
it with a number of Debian leaders and they're all very positive about it.
[...]

I'm not sure if I totally missed it as it came in, or I skimmed through it and thought WTF?! Dude on crack or I just forgot I need to reply to this email , but I'd swear it was the former. Not long after, no-name-yet.com popped up, the rumours started spreading around Debian channels. Luckily, I got a job at LliureX two months later, where I worked during the following 2 years, but that's another story. I guess it was July or so when Ubuntu was made public, and Mark and his secret team organised a conference (blog entries [1] [2] [3] [4] [5]), just before the Warty release, and I was invited to it, for the same reasons I got that email. During that conference, probably because Mark sent me some email and I applied a filter to get to it, I found the lost email, and felt like digging a hole to hide for a LONG while. I couldn't believe the incredible opportunity I had missed. I went to Mark and said "hey, you're not going to believe this", and he did look quite surprised about someone being such an idiot. I wonder if I should reply to his email today...

When the usual suspects in the secret Spanish Debian Cabal channel read this blog post, they decided Mark deserved a reply, even if it would hit his inbox more than three and a half years late. :) With great care, we crafted an email that would look genuinely stupid in late 2007, but just arrogant and idiotic in 2004, when Ubuntu was just an African word, and the GNU/Linux distribution landscape was quickly evolving at the time, Gentoo Linux had the posh distribution crown, that Debian had held for quite a few years. I even took enough care to forge the X-Operating-System and User-Agent headers so they matched whatever was current in Debian in February 2004, and of course, top-posting seemed most appropriate. So Mark woke up that Monday, fired up his email client, and got... this:

Hi Mark,
Thanks for your email. I nearly deleted this e-mail because for some
reason I thought it was targetted spam.
Your project looks very interesting, almost like a dream come true.
However, I feel a bit uneasy about your proposal. Something just doesn't
fit.
Why would someone start a company to work on /yet another/ Debian
derivative? Have you heard about Progeny's sad story? I think it's a
great example to show that Debian users don't want Debian-based distros,
they want people to work on the "real thing". Besides, I don't think
there's much more place for successful commercial distros, with Red Hat
and SuSE having well-established niches in the US and Europe.
Also, why focus on Debian specifically, Why not, for example, Gentoo,
which has a lot of buzz these days, and looks poised to be the next big
distribution?
To be honest, I think only a few people have the stamina or financial
stability to undertake a project like this, so I'd like to know
a bit more about you, and details on how you plan to sustain the
expenses.
Those are the main issues that worry me about your project. Other than
that, I would be interested in taking part in it, as I'm currently
unemployed and working on something Debian-based would be just too good
to miss.
You can reach me at +34 123 45 67 89, or if you feel like flying people
around Europe, I probably can be in the UK whenever it fits you.
Thanks, and hoping to hear from you again,
Jordi

Jordi! I just got this now! Did you recently flush an old mail queue?

With thanks to all the Spanish Cabal members who were involved!

A year ago, I posted my reading list for 2010. I listed a few highlights, and a link to my Goodreads page, pointing out that this wasn t necessarily a goal, just a list of things that sounded interesting. I started off with Homer s Iliad, which I tremendously enjoyed and found parallels to modern life surprisingly common in that ancient tale. I enjoyed it so much, in fact, that I quickly jumped to a book that wasn t on my 2010 list: The Odyssey. I made a somewhat controversial post suggesting that the Old Testament of the Bible can be read similar to how we read The Odyssey. Homer turned out to be much more exciting than I d expected. Jordan s Fires of Heaven (WoT #5) was a good read, though it is one of those books that sometimes is action-packed and interesting, and other times slow-moving and almost depressing. I do plan to continue with the series but I m not enjoying it as much as I did at first. War and Peace is something I started late last year. I m about 400 pages into it, which means I ve not even read a third of it yet. It has some moving scenes, and is a fun read overall, but the work it takes to keep all the many characters straight can be a bit frustrating at times. Harvey Cox s The Future of Faith was one of the highlights of the year. A thought-provoking read by someone that embraces both science and religion, and shows a vision of religion that returns to its earlier roots, less concerned about what particular truths a person believes in than it is about more fundamental issues. Marcus Borg s Jesus: Uncovering the Life, Teachings, and Relevance of a Religious Revolutionary began with a surprisingly engaging history lesson on how agriculture caused the formation of domination societies. It also described in a lot of detail how historians analyze ancient texts their drafting, copying, etc. It paints a vivid portrait of Jewish society in the time that Jesus would have lived, and follows the same lines of thought as Cox regarding religion finally moving past the importance of intellectual assent to a set of statements. Among books that weren t on my 2010 list, I also read and here I m not listing all of them, just some highlights: The Cricket on the Hearth in something of a Christmastime tradition of reading one of the shorter Dickens works. I enjoyed it, but not as much as I enjoyed A Christmas Carol last year. Perhaps I made up for that by watching Patrick Stewart as Scrooge instead. How to Disappear Completely was a fun short humorous read, with a very well-developed first-person narrative. Paralleling my interest in amateur radio, I read and studied three books in order to prepare myself for the different exams. In something of a surprise, I laughed a lot at Sh*t My Dad Says, which was more interesting and funny than I expected it to be. All I can say is that Justin s got quite the dad and quite the interesting childhood. I even read two other recent releases: The Politician (about John Edwards) and Game Change (about the 2008 presidential race). Both were interesting, vibrant, and mostly unsourced so hard to know exactly how much to take from them. And finally, reflecting on and travel before my first trip to Europe, Travel as a Political Act, which encourages us to find the fun in my cultural furniture rearranged and my ethnocentric self-assuredness walloped. And that was fun. Now to make up the 2011 list

As I mentioned recently, the Ubuntu Technical Board is reviewing the most popular topics in Ubuntu Brainstorm and coordinating official responses on behalf of the project. This means that the most popular topics on Ubuntu Brainstorm receive expert answers from the people working in these areas. This is the first batch, and we plan to repeat this process each quarter. We ll use feedback and experiences from this run to improve it for next time, so let us know what you think. Power management (idea #24782) Laptops are now outselling desktops globally, and laptop owners want to get the most out of their expensive and heavy batteries. So it s no surprise that people are wondering about improved power management in Ubuntu. This is a complex topic which spans the Linux software stack, and certainly isn t an issue which will be solved in the foreseeable future, but we see a lot of good work being done in this area. To tell us about it, Amit Kucheria, Ubuntu kernel developer and leader of the Linaro working group on Power Management, contributed a great writeup on this topic, with technical analysis, tips and recommendations, and a look at what s coming next.

I am going to attempt to summarize the various use profiles and what Ubuntu does (or can do) to prolong battery life in those profiles. Power management, when done right, should not require the user to make several (difficult) choices. It should just work providing a good balance of performance and battery life.

IP address conflicts (idea #25648) IP addressing is a subject that most people should never have to think about. When something isn t working, and two computers end up with the same IP address, it can be hard to tell what s wrong. I was personally surprised to find this one near the top of the list on Ubuntu Brainstorm, since it seems unlikely to be a very common problem. Nonetheless, it was voted up, and we re listening. There is a tool called ipwatchd which is already available in the package repository, and was created specifically to address this problem. This seems like a further indication that this problem may be more widespread than I might assume. The idea has already been marked as implemented in Brainstorm based on the existence of this package, but that doesn t help people who have never heard of ipwatchd, much less found and installed it. What do you think? Have you ever run into this problem? Would it have helped you if your computer had told you what was wrong, or would it have only confused you further? Is it worth considering this for inclusion in the default install? Post your comments in Brainstorm. Selecting the only available username to login (idea #6974) Although Linux is designed as a multi-user operating system, most Ubuntu systems are only used by one person. In that light, it seems a bit redundant to ask the user to identify themselves every time they login, by clicking on their username. Why not just preselect it? Indeed, this would be relatively simple to implement, but the real question is whether it is the right choice for users. Martin Pitt of the Ubuntu Desktop Team notes that consistency is an important factor in ease of use, and asks for further feedback.

So in summary, we favored consistency and predictablility over the extra effort to press Enter once. This hasn t been a very strong opinion or decision, though, and the desktop team would be happy to revise it.

Icon for .deb packages (idea #25197) Building on the invaluable efforts of Debian developers, we work hard to make sure that people can get all of the software they need from Ubuntu repositories through Software Center and APT, where they are authenticated and secure. However, in practice, it is occasionally necessary for users to work with .deb files directly. Brainstorm idea 25197 suggests that the icon used to represent .deb packages in the file manager is not ideal, and can be confusing. Matthew Paul Thomas of the Canonical Design Team responds with encouragement for deb-thumbnailer, which makes the icon both more distinctive and more informative. He has opened bug 685851 to track progress on getting it packaged and into the main repository.

I have reviewed the proposed solutions with Michael Vogt, our packaging expert. Solution #1 is straightforward, but we particularly like solutions #5 and #10, using a thumbnailer to show the application icon from inside each package.

Keeping the time accurate over the Internet by default (idea #25301) It s important for an Internet connected computer to know the correct time of day, which is why Ubuntu has included automatic Internet time synchronization with NTP since the very first release (4.10 warty ). So some of us were a little surprised to see this as one of the most popular ideas on Ubuntu Brainstorm. Colin Watson of the Ubuntu Technical Board investigated and discovered a case where this wasn t working correctly. It s now fixed for Ubuntu 11.04, and Colin has sent the patches upstream to Debian and GNOME.

My first reaction was hey, that s odd I thought we already did that? . We install the ntpdate package by default (although it s deprecated upstream in favour of other tools, but that shouldn t be important here). ntpdate is run from /etc/network/if-up.d/ntpdate, in other words every time you connect to a network, which should be acceptably frequent for most people, so it really ought to Just Work by default. But this is one of the top ten problems where users have gone to the trouble of proposing solutions on Brainstorm, so it couldn t be that simple. What was going on?

More detail in GNOME system monitor (idea #25887) Under System, Preferences, System Monitor, you can find a tool to peek under the hood at the Linux processes which power every Ubuntu system. Power users, hungry for more detail on their systems inner workings, voted to suggest that more detail be made available through this interface. Robert Ancell of the Ubuntu Desktop Team answered their call by offering to mentor a volunteer to develop a patch, and someone has already stepped up with a first draft. Help the user understand when closing a window does not close the app (idea #25801) When the user clicks the close button, most applications obediently exit. A few, though, will just hide, and continue running, because they assume that s what the user actually wants, and it can be hard to tell which has happened. Ivanka Majic, Creative Strategy Lead at Canonical, shares her perspective on this issue, with a pointer to work in progress to resolve it.

This is more than a good idea, it s an important gap in the usability of most of the desktop operating systems in widespread use today.

Ubuntu Software Centre Removal of Configuration Files (idea #24963) One feature of the Debian packaging system used in Ubuntu is that it draws a distinction between removing a package and purging it. Purging should remove all traces of the package, such that installing and then immediately purging a package should return the system to the same state. Removing will leave certain files behind, including system configuration files and sometimes runtime data. This subtle distinction is useful to system administrators, but only serves to confuse most end users, so it s not exposed by Software Center: it just defaults to removing packages. This proposal in Ubuntu Brainstorm suggests that Software Center should purge packages by default instead. Michael Vogt of the Ubuntu Foundations Team explains the reasoning behind this default, and offers an alternative suggestion based on his experience with the package management system.

This is not a easy problem and we need to carefully balance the needs to keep the UI simple with the needs to keep the system from accumulating cruft.

Ubuntu One file sync progress (idea #25417) Ubuntu One file synchronization works behind the scenes, uploading and downloading as needed to replicate your data to multiple computers. It does most of its work silently, and it can be hard to tell what it is doing or when it will be finished. John Lenton, engineering manager for the Ubuntu One Desktop+ team, posts on the AskUbuntu Q&A site with tools and tips which work today, and their plans to address this issue comprehensively in the future. Multimedia performance (idea #24878) With a cornucopia of multimedia content available online today, it s important that users be able to access it quickly and easily. Poor performance in the audio, video and graphics subsystems can spoil the experience, if resource-hungry multimedia applications can t keep up with the flow of data. Allison Randal, Ubuntu Technical Architect, answers with an analysis of the problem and the proposed solutions, an overview of current activity in this area, and pointers for getting involved.

The fundamental concern is a classic one for large systems: changes in one part of the system affect the performance of another part of the system. It s modestly difficult to measure the performance effects of local changes, but exponentially more difficult to measure the network effects of changes across the system.

Colin Watson is not a high-profile Debian figure, you rarely see him on mailing lists but he cares a lot about Debian and you will see him on Debconf videos sharing many thoughtful comments. I have the pleasure to work with him on dpkg as he maintains the package in Ubuntu, but he does a lot of more interesting things. I also took the opportunity to ask some Ubuntu specific questions since he s worked for Canonical since the start. Read on. My questions are in bold, the rest is by Colin. Who are you? Hi. I m 32 years old, grew up in Belfast in Northern Ireland, but have been living in Cambridge, England, since I was 18. I m married with a stepson and a daughter. I became interested in Debian due to the critical mass of Debian work happening in Cambridge at the time (and perhaps more immediately because my roommate was running Debian: hey, what s that? ), started doing random bits of development in 2000, and joined as a developer in 2001 (a really exciting time, with lots of new people joining who became integral parts of the project). I d only really been intending to do QA work and various bits of packaging around the edges, and maybe some work on the BTS, but then Fabrizio Polacco died and I took over man-db from him, and it sort of snowballed from there. I graduated from university shortly before becoming a Debian developer. I worked for a web server company (Zeus), then a hardware cryptography company (nCipher), before moving to work for Canonical in 2004, since when I ve been working full-time on Ubuntu. By this point, I suspect that going back to work in an office every day would be pretty tough. What s your biggest achievement within Debian or Ubuntu? One thing I should say: I rarely start projects. Firstly I don t think I m very good at it, and secondly I much prefer coming on to an existing project and worrying away at all the broken bits, often after other people have got bored and wandered off to the next new and shiny thing. That s probably why I ended up in the GNU/Linux distribution world in the first place, rather than doing lots of upstream development from the start I like being able to polish things into a finished product that we can give to end users. So, I ve had my fingers in a lot of pies over the years, doing ongoing maintenance and fixing lots of bugs. I think the single project I m most proud of would have to be my work on the Debian installer. I joined that team in early 2004 (a few months before Canonical started up) partly because I was a release assistant at the time and it was an obvious hot-spot, and partly because I thought it d be a good idea to make sure it worked well on the shiny new G4 PowerBook I d just treated myself to. I ended up as one of the powerpc d-i port maintainers for a while (no longer, as that machine is dead), but I ve done a lot of core work as well: much of the work to put progress bars in front of absolutely everything that used to have piles of text output, rescue mode, the current kernel selection framework, a good deal of udev support, several significant debconf extensions, lots of os-prober work, and I think I can claim to be one of the few people who understands the partitioner almost top to bottom. d-i is the very first thing many of our users see, and has a huge range of uses, from simple desktop installs to massive corporate deployments; it s unspeakably important that it works well, and it s a testament to its design that it s been able to trundle along without actually very much serious refactoring for the best part of five years now. I have a soft spot for man-db too. It was my first major project in Debian, starting out from an embarrassingly broken state, and is now nice and stable to the point where I recently had time to spawn a useful generic library out of it (libpipeline). What are your plans for Debian Wheezy? d-i has a lot of code to deal with disks and partitions. Of course a lot of it is in the partitioner, and for that we use libparted so we don t have to worry very much about the minutiae of device naming. But there are several other cases where we do need to care about naming, mainly before the partitioner when detecting disks, and after the partitioner when installing the boot loader. Back in etch, we introduced list-devices , which abstracted away the disk naming assumptions involved in hardware detection. In wheezy, I would like to take all the messy, duplicated, and error-prone code that handles disk naming in the boot loader installers, and design a simple interface to cover all of them. This has only got more important following the addition of the kFreeBSD and Hurd d-i ports in squeeze, but it bites us every time we notice that, say, CCISS arrays aren t handled consistently, and it s a pain to test all that duplicated code. I d also like to spread the use of libpipeline through C programs in the archive, which I think has potential to eliminate a class of security vulnerabilities in a much simpler way than was previously available. If you could spend all your time on Debian, what would you work on? I would love to systematically reduce the need for the current mass of boot loaders. There s a significant cost to having so much variation across architectures here: it s work that needs to be done in N different places, the wildly differing configuration means that d-i has to have huge piles of code to manage them all differently, and there are a bunch of strange arbitrary limitations on what you can do. The reason I m working on GRUB 2 is that, in my view, it s the project with the best chance of centralising all this duplicated work into a single place, and making it easier to bring up new hardware in future (in a way that doesn t compromise software freedom, as many proprietary boot loaders of the kind often found on phones do). Of course, with flexibility tends to come complexity, and some people have a natural objection to that and prefer something simpler. The things I don t quite have time to do here are to figure out a coherent way to address the specific over-complexity problems people have with the configuration framework while still keeping the flexibility we need, and to do enough QA and porting work to be able to roll out GRUB 2 at installation time to all the Debian architectures it theoretically supports. What s the biggest problem of Debian? Backbiting, and too much playing the man rather than the ball. With one or two honourable exceptions, I ve largely stopped reading most Debian mailing lists since it just never seems a productive way to spend time compared to writing code and fixing bugs; and yet I m conscious that they re one of the primary means of communication for the project and I m derelict in not taking part in them. I do find it a bit frustrating that people are seen primarily in terms of their affiliations. I suppose it s natural for people to see me as an Ubuntu guy , but I don t really see myself that way: I ve been working on Debian for nearly twice as long as I ve been working on Ubuntu, and, while I care a great deal about both projects, I ve put far more of my own personal time into Debian and I try to make sure that a decent number of the things I m involved with there aren t to do with work. Work/life separation is a good thing, not that I m very good at it. Generally speaking, when I m working on Debian, I m doing so as a Debian developer, because I want Debian to be better. When that s not the case, if it matters, I try to indicate it explicitly. You re working for Canonical since Ubuntu s inception. If you were Mark Shuttleworth, is there something that you would have done differently? We had many good intentions when we founded Ubuntu. We also had a huge amount of work to deliver, to the point where it wasn t at all clear whether it would be possible (the warty release was named based on the expectations of it, after all, and came out much more usable than we d dared to hope). In hindsight, it might have helped to be quieter about our good intentions, so that we could exceed expectations rather than in some cases failing to meet them. That might have set a very different tone early on. (Personally, I m happy I m not Mark. The decisions in my office are much easier to take.) It seems to me that the community part of Ubuntu is much more eager to cooperate with Debian than the corporate part. It s probably just that more and more Canonical employees are not former Debian contributors. Do you also have this feeling? Are there processes in place to ensure everybody at Canonical is trying to do the right thing towards Debian cooperation? Just to be clear, I m wearing my own hat here which, ironically, is a fedora rather than a company hat. It makes sense for Canonical to be taking on more non-Debian folks; after all, we can t simply hire from the Debian community forever, and a variety of backgrounds is healthy. As you say, it may well be natural that Ubuntu developers who don t work for Canonical are more likely to have a Debianish background, as it tends to take something significant to get people to switch to a very different family of GNU/Linux distributions, and changing jobs is one of the most obvious of those things. Certainly, there was a definite sense among the early developers that we were all part of the Debian family and cared about the success of Debian as well. As Ubuntu has developed its own identity, people involved in it now tend to care primarily about the success of Ubuntu. At the same time, pragmatically, it s still true that getting code changes into Debian is one of the most economical ways to land them; changes made in Debian or upstream land once and tend to stay in place, while changes made only in Ubuntu incur an ongoing merge overhead, which is not at all trivial. In many ways it s human nature to try to fulfil your immediate goals in the most direct way possible. If your goal is to deliver changes to Ubuntu users, then it s natural to concentrate on that rather than looking at the bigger picture (which takes experience). Debian developers often fail to send changes upstream for much the same reason, although there s more variation there because they re normally working on Debian of their own volition and thus tend to have wider goals; the economics are more or less parallel though. Thus, I think the best way to improve things is to make it the path of least resistance for Ubuntu developers to send changes to Debian. We re already seeing how this works with the Ubuntu MOTU group; if you send a patch for review, or work on merging a package from Debian, very often the response includes have you sent these changes to Debian? . We re working on both streamlining our code review through a regular patch pilot programme and requiring more code review for changes in general, so I think this will be a good opportunity to ask more people to work with Debian when they propose changes to Ubuntu. For myself, this may be obvious, but I notice that I m much better at getting changes into Debian when I already have commit access to the Debian package in question. All the work on improving collaborative maintenance in Debian can only help, for Ubuntu as well as for everyone else. It doesn t make so much difference for large changes that require extensive discussion, but there are lots of small changes too. Canonical is upstream of many software projects (unity, indicators infrastructure, etc.). Why aren t those software immediately packaged in Debian? Do you think we can get this to change? I m not sure what the right approach is here, particularly as I haven t been involved with much of that on the Ubuntu side. I suspect it would be helpful to look at this in a similar way to Ubuntu changes in general. It s understandable that those developers have getting changes into Ubuntu as their first goal. And yet, having code in Debian offers a wider, and often technically adept, audience, and most developers like having their code reach a wider audience even if it s not their first priority, particularly if that audience is likely to be able to help with finding problems and fixing bugs. It should be seen as something beneficial to both distributions. The hardest problems will be with things that aren t merely optional add-ons (which should generally be fairly non-controversial in Debian, given the breadth of the archive in general the existence of things like bzr and germinate as Debian packages was never a hard question), but which require changes in established packages. For example, gnome-power-manager in Ubuntu is built with application indicator support, and that s an important part of having a good indicator-based panel: a lot of the point of indicators is consistency. Since I do very little desktop work myself, I don t know exactly what would be involved in making it possible to choose this system based on a Debian desktop, but I think it s probably a bit more complicated than just making sure all the new packages exist in Debian too. Obviously you have to start somewhere. Is there someone in Debian that you admire for his contributions? Christian Perrier is absolutely tireless and has done superb things for the state of translations in Debian. And Russ Allbery, even aside from his fine ongoing work on policy, Lintian, and Kerberos, is a constant voice of sanity and calmness. Release management is incredibly hard work, as I know from my own experience, and anyone who can sustain involvement in it for a long period is somebody pretty special. Steve Langasek and I got involved at about the same time but he outlasted me by quite a few years. He deserves some kind of medal for everything he s done there.

This essay is a summary of my presentation at the workshop Inlaws and Outlaws, held on August 19-20, 2010 in Split, Croatia. The workshop brought together advocates of piracy with participants in the free culture and free software movements.

In Why Software Should Not Have Owners, Richard Stallman explains that, if a friend asks you for a piece of software and the license of the software bars you from sharing, you will have to choose between being a bad friend or violating the license of the software. Stallman suggests that users will have to choose between the lesser of two evils and will choose to violate the license. He emphasizes that it's unfair to ask a user to make such a choice. Over the past few years, pirate parties have grown across much of the developed world. Of course, piracy remains the primary means of distributing media across most of the rest. Advocates of access to information have gathered and organized under the "pirate" banner, representing the choice of sharing with friends over compliance with license terms. The free/libre and open source software (FLOSS) and free culture movements seem to have a confused and conflicted reaction to all this. On one hand, major proponents of several pirate parties are FLOSS and free culture stalwarts and several pirate parties have made FLOSS advocacy a component of their political platforms. Pirate Parties' clear opposition to software patents and DRM resonates with both FLOSS and free culture communities. On the other hand, FLOSS leaders, including Stallman, have warned us about "pirate" anti-copyright policies. Free culture leaders, like Lawrence Lessig, have repeatedly and vociferously denounced piracy, treated even the intimation of an association with piracy as an affront, and systematically distanced themselves and their work from piracy. Should FLOSS and free culture advocates embrace pirates as comrades in arms or condemn them? Must we choose between being either with the pirates or against them? Our communities seem to have no clearly and consistently articulated consensus. I believe that, unintuitively, if you take a strong principled position in favor of information freedom and distinguish between principles and tactics, a more nuanced "middle ground" response to piracy is possible. In light of a principled belief that users should be able to share information, we can conclude there is nothing ethically wrong with piracy. Licenses have the power of the law but they are protected by unjust "intellectual property" laws. That said, principles are not the only reason activists choose to do things. Many political stunts are bad ideas not because they are wrong, but because they won't work and have negative side effects. Tactics matter too. Even though there might not be anything ethically wrong with piracy from the perspective of free software or free culture, it might still be a bad idea. There are at least three such tactical reasons that might motivate free software and culture to not support piracy or participate in pro-piracy movements and politics. First, a systematic disrespect for copyright undermines respect for all licenses which have been of a huge tactical benefit to free software and a increasingly important factor in the success of free culture. Copyleft licenses like the GPL or CC BY-SA have power only because copyright does. As Stallman has suggested, anti-copyright actions are anti-copyleft. That needn't be an argument against attempts to limit copyright. Indeed, I think we must limit and reduce copyright. But we must tread carefully. In the current copyright climate, I believe that copyleft offers a net advantage. Why should others respect our licenses if we don't respect theirs? Looking at the long term, we must weigh the benefits of promoting the systematic violation of proprietary licenses with the benefits of adherence to free software and free culture. Second, piracy is fundamentally reactionary. Part of its resonance as a political symbol comes from the fact that the piracy represents a way that consumers of media can fight back against a set of companies which have attacked them -- with lawsuits, DRM systems, and demonization in propaganda -- for sharing in ways that most consumers think are natural and socially positive. But piracy focuses on reaction rather the fundamental importance of sharing that drives it. As a result, most pirates do not support, or are even familiar with, a principled approach to access to information. As a result, many piracy advocates who speak out against DRM on DVDs will be as happy to use NetFlix to stream DRMed movies for $5 a month as they were to download for free. The best rallying cries do not always translate into be the most robust movements. Third, through its focus on a reaction, a dialog about piracy avoids engagement with the tough questions of what we will replace the current broken copyright system with. A principled position suggests that it is our ethical prerogative to create alternative models. The free software movement has succeeded because it created such a prerogative and then, slowly over time, provided examples of workable alternatives. A principled position on free software did not require that one provide working new systems immediately, but it makes the development of creative, sustainable approaches a priority. Attacking the system without even trying to speak about alternative modes of production is unsustainable. Free software and free culture call for a revolution. Piracy only calls for a riot. Piracy, in these three senses, can be seen as tactically unwise, without necessarily being unethical. By taking a principled position, one can go build on, and go beyond, RMS's comment. On free culture and free software's terms, we can suggest that piracy is not ethically wrong, but that it is an unwise way to try to promote sharing. Without being hypocritical, we can say: "I don't think piracy is unethical. But I also do not support it."

As a lot of people are coming to my blog to read the installing instructions for Debian on the GuruPlug Server Plus, I shall not hide my opinion about it: It is a major design and QA fail. Don't waste your money on it.

The power supply Although I've ordered the Guruplug pretty early with the promise, that I'd have it in April, it arrived at the end of May due to QA issues with the power supply. While I appreciate that they didn't deliver broken power supplies, I would have preferred not to receive one which was "fixed" by somebody who uses the soldering iron like an axe. Here are some macro photos to show the gory details:

Software issues The version of UBoot which shipped with the device was only able to boot from NAND and network. Booting from USB failed and ext2 support was missing, too. Didn't have a look if the community came up with a fixed UBoot version yet, but in my opinion a piece of hardware for >100 EUR should not have such flaws.

Thermal issues Using the Guruplug with more than one 100 MBit/s connection is just not possible, as it would toast itself to death. For the details have a look at this discussion in the NewIT forum, it links to a lot of interesting photos and postings. This issue is a major design and QA failure. Even without knowing what the datasheets say, it is easy to imagine that a thin piece of alloy is not the proper way to cool a CPU and network chip. Especially not when it is mounted with cheapish pads instead of a proper paste. As it seems the plan was to send the heat to the shielding of the network/USB/eSata ports (the area is marked red as my first plan was to remove that part of the alloy and reuse the heat-spreader), a strong indication for that is that this is the only area with holes for air circulation. I could imagine that it was not possible to have these holes next to the PSU, which was mounted above the heat-spreader, to avoid electrical shocks. As there was no other opening for the heat to leave the case, even the microSD card became pretty hot - I've measured temperatures around 60 deg. C next to the card - while CPU and 100MB/s network were idling. The official information from GlobalScale Technologies is that only 10/100MBit/s should be used as workaround to avoid overheating until a "Professional Upgrade Kit" is released. As mentioned here the upgrade kit announcement was removed silently from GST's website. To be honest, this doesn't make me wonder. There is no way to fix the Guruplug with an external fan or any other external magic as the only way to fix it is to cool the CPU and networking chip properly. There are various workarounds for the cooling issues posted to the forums. I've decided to rip out the power supply and heat spreader out of the case and get a nice external PSU. The new connector is mounted, ready to supply the GuruPlug's board with power. Currently I'm waiting for the new heat sinks and glue to arrive. Then I'll give it a try to mount eveything in the small case again, probably with some additional air holes. As soon as I have a workign solution, I'll blog about it again.

As a lot of people are coming to my blog to read the installing instructions for Debian on the GuruPlug Server Plus, I shall not hide my opinion about the Guruplug Server Plus: It is a major design and QA fail. Don't waste your money on it.

For the details have a look at this discussion in the NewIT forum, it links to a lot of interesting photos and postings. This issue is a major design and QA failure. Even without knowing what the datasheets say, it is easy to imagine that a thin piece of alloy is not the proper way to cool a CPU and network chip. Especially not when it is mounted with cheapish pads instead of a proper paste. As it seems the plan was to send the heat to the shielding of the network/USB/eSata ports (the area is marked red as my first plan was to remove that part of the alloy and reuse the heat-spreader), a strong indication for that is that this is the only area with holes for air circulation. I could imagine that it was not possible to have these holes next to the PSU, which was mounted above the heat-spreader, to avoid electrical shocks. As there was no other opening for the heat to leave the case, even the microSD card became pretty hot - I've measured temperatures around 60 deg. C next to the card - while CPU and 100MB/s network were idling. The official information from GlobalScale Technologies is that only 10/100MBit/s should be used as workaround to avoid overheating until a "Professional Upgrade Kit" is released. As mentioned here the upgrade kit announcement was removed silently from GST's website. To be honest, this doesn't make me wonder. There is no way to fix the Guruplug with an external fan or any other external magic as the only way to fix it is to cool the CPU and networking chip properly. There are various workarounds for the cooling issues posted to the forums. I've decided to rip out the power supply and heat spreader out of the case and get a nice external PSU. The new connector is mounted, ready to supply the GuruPlug's board with power. Currently I'm waiting for the new heat sinks and glue to arrive. Then I'll give it a try to mount eveything in the small case again, probably with some additional air holes. As soon as I have a workign solution, I'll blog about it again.

One of my favorite conferences is HOPE, which I have missed the last 2 times as I was away from NYC, so I am glad I am around this year. I find it especially valuable when there is some controversy brewing in the air, as there is with Wikileaks, Adrian Lamo, and Manning. I am also giving a talk, description below, with a fabulous postdoctoral researcher, Finn Brunton, who works on spam! But we will be talking about pleasure, trickery, and exploitable media for activists. Our talk is late, like really late: 11:00 PM on Saturday night. At first I was a bit annoyed at the scheduling but then I figured, when will i ever give a talk at 11:00 PM?

Following a brief lecture on Project Chanology, the question will be posed: how can we harness the power of lulzy virality, of pleasure, of trickery, of spectacular trolling for purposes above and beyond sharing the wisdom of Advice Dog? It ll start with a brief look at great activist media in the past, from Guernica and the picture of the whole Earth to projects by the Yes Men - how they spread ideas and helped people get informed, organize, and act. What makes the creation of lulzy memes different? Learn about how to create exploitable forms and rapid variations, and mechanisms for bringing the best stuff forward. Can we make media memes with goals beyond lulz, and teach activists who ve never heard of 4chan to make them too? Part lecture, part workshop, this will feature cameos by Rageguy, Pablo Picasso, V, alt.pave.the.earth, Kathe Kollwitz, Courage Wolf, Stewart Brand, Sarah Palin, Batman, Goya, Philosoraptor, Adolf Hitler, Trollface, Shepard Fairey, Joseph Ducreux, David Cameron, lots of Spartan warriors, and lots and lots of (trollish) cats.

Since we had little snow this year shows a negative trend. Less days spent snowboarding, less meters of altitude. In December and around christmas I basically went snowboarding instead of talking a walk, stopping after an hour or two. The first reasonable day was January 23rd. My season ended April 17th with a perfect day at Warth. Here is the balance sheet:

	2005/06	2006/07	2007/08	2008/09	2009/10
number of (partial) days	25	17	29	37	30
Dam ls	10	10	5	10	16
Diedamskopf	15	4	24	23	13
Warth/Schr cken	0	3	0	4	1
total meters of altitude	124634	74096	219936	226774	202089
highscore	10247m	8321m	12108m	11272m	11888m
# of runs	309	189	503	551	462

On good days I had problems stopping ;-), ending up with three 11000m+ days. Not included above is one day in Brand (with the company I work for, I also did this last year) and my very first time at Lech am Arlberg. The road from Bregenzerwald to Lech is usually closed in winter due to danger of avalanches which is what stopped me before. This year it was open for some time due to little snow. I had great day there, although the snow cannons did not manage to cover all rocks.

For a few weeks now, aptitude is really slow updating the package list downloading the lists is actually fast as normal but it always waits for a minute or so with a 99% [Warten auf Kopfzeilen] (Waiting for headers) message. I tried apt-get update same problem. Now the funny thing is: LANG=C apt-get update or LANG=C aptitude -u works just fine! I also tested with LANG=de_DE, it_IT, fr_FR and even en_US always slow, so it looks it always occurs when LANG is not set to C? Anyone else noticed this problem? I skimmed through the bug reports of apt, but didn t find a similar bug. Update: Looks like google-chrome is the problem! Commenting out the content of /etc/apt/sources.list.d/google-chrome.list, as Jaime suggested in the comments, everything worked fine again.

As I mentioned, I headed to Pittsburgh last week to give some talks at CMU and find out something about what they're doing there. Despite the dire weather that had closed the airport the day before, I had no trouble getting into town and was soon safely in a hotel room with a heater that seemed oddly enthusiastic about blasting cold air at me for ten seconds every fifteen minutes. Unfortunately, it seems that life wasn't as easy for everyone - ten minutes after I arrived, I got a phone call telling me that the city had asked CMU to cancel classes the next day.

This turned out to be much less of a problem than I'd expected - whether because of their enthusiasm to learn about ACPI or because they simply hadn't noticed the alert telling them about the cancellation, a decent body of students turned up the next morning. After a brief chat with Mark Stehlik, the assistant dean for undergraduate education, I headed off to the lecture hall. The fact that I can now just plug my laptop into a VGA cable and have my desktop automatically extend itself continues to amaze me, as does OpenOffice's seemingly unerring ability to get confused about which screen should have my content and which should be showing me the next slide. Nevertheless, facts were imparted and knowledge dropped on those assembled. I'm even reasonably sure that the contents were factually accurate, which is a shame because the most attractive part of teaching always struck me as being able to lie to students who will then happily regurgitate whatever you tell them because in case it turns up on the exam. Perhaps this is why I'm safer out of academia.

Lunch offered an opportunity to visit the Red Hat sponsored lab, which was pleasingly located somewhere other than a basement. The guy on the right of the picture is Greg Kesden, the director of undergraduate laboratories in CS there - it was wonderful to get an opportunity to see the machines getting used, and students seemed genuinely appreciative of the facility.

After lunch I spent a while talking to Satya about the Internet Suspend and Resume project. This is an impressive combination of virtualisation and migration, using a Fedora-based live image to bring up an OS on arbitrary hardware before downloading a machine image and launching it. The majority of the data is pulled in on demand, meaning that initial performance can be slow but ensuring that data is only downloaded if it's needed. When the user is finished, the delta between the original image and the new one can be pushed back to the server while remaining cached on the local machine in case the image is used again.

It's an interesting approach, combining the flexibility of thin clients with the advantages of having actually useful computing power at the local end. There's a few functional awkwardnesses, such as some VMs being unhappy if images are migrated between machines with different CPU features, and it obviously benefits from having significant bandwidth. But the idea of being able to combine the convenience of a floating session with the knowledge that you can still keep copies of your data on you is an attractive one, and I'd love a future where I can move my session between my laptop and a desktop.

After that there was some time to talk to Bill Scherlis and Philip Lehman about the software engineering courses that CMU run. Part of the minor in software engineering includes a course requirement to make a meaningful contribution to an existing software project, from design through to submission and upstream acceptance. I had the opportunity to talk to a couple of the students about this and the differences they found between working with the Mozilla and Chrome communities, which I'll try to write up at some point.

Finally I gave a presentation on Fedora and some of the issues that we face in providing a useful OS when patents and recalcitrant hardware vendors do their best to thwart us. Despite the ice outside and the significantly-below-freezing temperatures, enough people turned up that sorties had to be sent out to find extra chairs. It was great to see how interested people were in learning about what we do, although it's probably the case that the free pizza did help encourage people.

After that it was an early trip back to the airport, where I found that my plane was delayed and the only "restaurant" still open was McDonalds. Even so, I left with the feeling that it had been an interesting and educational visit. Many thanks to David Eckhardt, who runs the OS course I presented to and who looked after me all day - thanks too to Joshua Wise who picked me up when David was running late due to the ground being covered with blocks of ice.

Popular Mechanics has a good article about 911 [1]. Experts in all the relevant fields were consulted to debunk popular myths. It s an old article but I hadn t read it before and learned a lot. Former CIA analyst Raw McGovern and former FBI attorney/special agent Coleen Rowley, a colleague in Veteran Intelligence Professionals for Sanity wrote an interesting article titled Why Counter-Terrorism Is in Shambles [2]. Such sanity from people who are associated with the intelligence industry is unusual. Gizmodo has an amusing and informative poster about the true risks of airline travel post 911 [3]. Reuters has an interesting article about drug smugglers using Gulfstream and 727 aircraft to smuggle cocaine from South America to Africa [4]. They claim a link to al Quaeda, but such a link seems tenuous from the evidence provided, it does seem reasonable to claim that groups who claim affiliation to al Quaeda are involved in smuggling anyone can claim anything really. An 8yo boy is on the TSA terrorism watch list , he regularly gets frisked when traveling by air [5]. His mother had a security clearance to fly on Air Force 2 when Al Gore was the Vice President, any sane security system would look at the parents rather than an 8yo child children of that age aren t going to independently become terrorists. The Dallas Observer has an interesting article by Kimberly Thorpe about how to beat debt collectors [6]. Apparently most debt collectors break the law in some way and can be sued for damages with a typical settlement of $3,500. Some debtors are suing multiple debt collectors, after one debt collector is successfully sued the debt is passed to another collector who also breaks the law. What I really like about this is that the community of people who sue debt collectors keep the industry honest and protect the majority of the population who don t have the time or interest for engaging in law suits. Read Write Web has an informative article about SourceForge being forced to deny access to people in Cuba, Iran, North Korea, Sudan and Syria [7]. A problem for free software developers is that we often don t know the location of the people we collaborate with so it s best to be as open as possible. This means that the US is not a good place to host servers, probably some part of the EU would be better. Also this sort of thing makes the field of free software development less welcoming to US citizens. Did the congress people learn nothing in high-school? They should know that someone who starts a campaign of ostracism may end up being in the small group. Google is developing a new Native Client (NaCl) system that seems to be like Microsoft ActiveX [8]. I can t imagine this doing anything that couldn t be done with Java, it seems most likely to just marginalise the less popular platforms which isn t in the best interests of Google. Kevin Kelly of the Technium wrote an interesting post about 1000 true fans [9]. The concept is that if you are doing creative work you only need 1000 dedicated fans who buy everything you sell to make a living. If you make $20 per year from each of the 1000 fans and you will earn enough to live. Make $100 per year from each of the 1000 fans and you will be earning more money than most people. The updates show that artists who try this aren t having much success yet, but the Internet population is still increasing dramatically PaxStreamline offers an innovation in commercial air-conditioning, apparently a significant amount of electricity is wasted on heating the air after chilling it excessively to remove moisture [10]. So instead of cooling it they use a liquid dessicant to extract the moisture. Ben Schwartz explains why you should never create files in H.264 or MPEG formats, unless you have a special commercial license then you (and your viewers) will all be liable for patent infringement for any type of commercial use [11]. Note that storing the data on a web site with Google adverts counts as commercial use. I wonder if all those digital cameras and mobile phones that create MPEG videos have appropriate licenses, maybe uploading a file created on your phone breaches the patent. J. K. Rowling (author of Harry Potter) gave an inspiring speech for Harvard graduates [12]. I particularly liked the following reference to her work for Amnesty International Choosing to live in narrow spaces leads to a form of mental agoraphobia, and that brings its own terrors. I think the willfully unimaginative see more monsters. They are often more afraid . Peter Eigen gave an interesting TED talk about the formation of Transparency International and the economic problems that are caused by corruption [13]. The Monthly Review has an interesting article about the failure of the US justice system [14]. The prison industrial complex has captured part of the US government, neo-liberalism is to blame. 59% of Americans agree that homosexuals ought to be able to serve in the U.S. military. But 70 percent believe that gays and lesbians ought to be able to serve in the military [15]. Apparently 11% of Americans think that gays and lesbians are better than homosexuals .
