Matthew Garrett: Canonical, Ubuntu and why I seem so upset about them all the time

I had no access to the internet for most of my childhood. Nobody in my area knew anything about programming. I learned a great deal from a number of CDs that included free software source code and archives of project mailing lists. When I got to university, I learned even more by being able to develop a Debian-based OS for use in our computer facilities. That gave me the experience and knowledge that I needed to become involved in Debian development, which in turn gave me the background required to be able to help Ubuntu become the first free software operating system to work out of the box on modern laptops. From there, I've been able to build my career around developing free software.

Ubuntu can be translated as "I am who I am because of who we all are". I am who I am because people made the choice to release their software under licenses that permitted examination, modification and redistribution. I am who I am because I was able to participate in communities that took advantages of those freedoms to produce new and better software. I am who I am because when my priorities differed from those of existing communities, it was still possible for me to benefit from their work and for them to benefit from mine.

Free software doesn't mean that the software is entirely free of restrictions. While a core aspect is the right to distribute modified versions of code, it has never been fundamental to free software that you be able to do so while still claiming that the code is the original version. Various approaches have been taken to make it possible for users to distinguish modified versions, ranging from simply including license terms that require modified versions be marked as such, to licenses that require that you change the name of the package if you modify it. However, what's probably the most effective approach has been to apply trademark law to the problem. Mozilla's trademark policy is an example of this - if you modify the code in ways that aren't approved by Mozilla, you aren't entitled to use the trademarks.

A requirement that you avoid use of trademarks in an infringing way is reasonable. Mozilla products include support for building with branding disabled, which makes it very straightforward for a user to build a modified version of Firefox that can be redistributed without any trademark issues. Red Hat have a similar policy for Fedora and RHEL[1] - you simply replace the packages that contain the branding and you're done.

Canonical's IP policy around Ubuntu is fundamentally different. While Mozilla make it clear that you simply no longer have a right to use the trademarks under trademark law, Canonical appear to require that you remove all trademarks entirely even if using them wouldn't be a violation of trademark law. While Mozilla restrict the redistribution of modified binaries that include their trademarks, Canonical insist that you rebuild everything even if the package doesn't contain any trademarks. And while Mozilla give you a single build option that creates binaries that conform with their trademark requirements, Canonical will refuse to tell you what you have to do.

When asked about this at SCALE earlier this year, Mark Shuttleworth claimed that Ubuntu's policy was consistent with that of other projects. This is inaccurate. Nobody else requires that you rebuild every package before you can redistribute it in a modified distribution - such a restriction is a violation of freedom 2 of the Free Software Definition, and as a result the binary distributions of Ubuntu are not free software. Nobody else refuses to discuss whether you're required to remove non-infringing trademarks in order to be able to redistribute. Nobody else responds to offers to make it easier for users to produce non-infringing derivatives with a flat refusal.

Mark claims that I'm only raising this issue because I work for a competitor and wish to harm Canonical. Nothing could be further from the truth. I began discussing this before working for my current employers - my previous employers had no meaningful market overlap with Canonical at all. The reason I care is because I care about free software. I care about people being able to derive new and interesting things from existing code. I care about a small team of people being able to take Ubuntu and make something better in the same way that Ubuntu did with Debian. I care about ensuring that users receive the freedom to do this without having to jump through a significant number of hoops in the process. Ubuntu has been a spectacularly successful vehicle for getting free software into the hands of users. Mark's generosity in funding this experiment has undoubtedly made the world a better place. Canonical employs a large number of talented developers writing high quality software, many of whom I'm fortunate enough to be able to call friends. And Canonical are squandering that by restricting the rights of their users and alienating the free software community.

I want others to be who they are because of my work and the work of all the others like me. Anything that makes that more difficult saddens me, and so I do what I can to fix it. I criticise Canonical's policies in the hope that we, as a community, can convince Canonical to agree that this kind of artificial barrier to modification hurts us more than it helps them. In many ways, Canonical remain one of our best hopes for broadening the reach of free software, and this is why it's unfortunate that they do so in a way that makes it more difficult for people to have the same experiences that I did.

[1] While it's easy to turn a trademark infringing version of RHEL into a non-infringing one, Red Hat don't provide publicly available binary packages for RHEL. If you get hold of them somehow you're entitled to redistribute them freely, but Red Hat's subscriber agreement indicates that if you do this as a Red Hat customer you will lose access to further binary updates - a provision that I find utterly repugnant. Its inclusion reduces my respect for Red Hat and my enthusiasm for working with them, and given the official Red Hat support for CentOS it appears to make no sense whatsoever. Red Hat should drop it.

Daniel Pocock: Giving up democracy to get it back

Do services like Facebook and Twitter really help worthwhile participation in democracy, or are they the most sinister and efficient mechanism ever invented to control people while giving the illusion that they empower us? Over the last few years, groups on the left and right of the political spectrum have spoken more and more loudly about the problems in the European Union. Some advocate breaking up the EU, while behind the scenes milking it for every handout they can get. Others seek to reform it from within. Yanis Varoufakis on motorbike Most recently, former Greek finance minister Yanis Varoufakis has announced plans to found a movement (not a political party) that claims to "democratise" the EU by 2025. Ironically, one of his first steps has been to create a web site directing supporters to Facebook and Twitter. A groundbreaking effort to put citizens back in charge? Or further entangling activism in the false hope of platforms that are run for profit by their Silicon Valley overlords? A Greek tragedy indeed, in the classical sense. Varoufakis rails against authoritarian establishment figures who don't put the citizens' interests first. Ironically, big data and the cloud are a far bigger threat than Brussels. The privacy and independence of each citizen is fundamental to a healthy democracy. Companies like Facebook are obliged - by law and by contract - to service the needs of their shareholders and advertisers paying to study and influence the poor user. If "Facebook privacy" settings were actually credible, who would want to buy their shares any more? Facebook is more akin to an activism placebo: people sitting in their armchair clicking to "Like" whales or trees are having hardly any impact at all. Maintaining democracy requires a sufficient number of people to be actively involved, whether it is raising funds for worthwhile causes, scrutinizing the work of our public institutions or even writing blogs like this. Keeping them busy on Facebook and Twitter renders them impotent in the real world (but please feel free to alert your friends with a tweet) Big data is one of the areas that requires the greatest scrutiny. Many of the professionals working in the field are actually selling out their own friends and neighbours, their own families and even themselves. The general public and the policy makers who claim to represent us are oblivious or reckless about the consequences of this all-you-can-eat feeding frenzy on humanity. Pretending to be democratic is all part of the illusion. Facebook's recent announcement to deviate from their real-name policy is about as effective as using sunscreen to treat HIV. By subjecting themselves to the laws of Facebook, activists have simply given Facebook more status and power. Data means power. Those who are accumulating it from us, collecting billions of tiny details about our behavior, every hour of every day, are fortifying a position of great strength with which they can personalize messages to condition anybody, anywhere, to think the way they want us to. Does that sound like the route to democracy? I would encourage Mr Varoufakis to get up to speed with Free Software and come down to Zurich next week to hear Richard Stallman explain it the day before launching his DiEM25 project in Berlin. Will the DiEM25 movement invite participation from experts on big data and digital freedom and make these issues a core element of their promised manifesto? Is there any credible way they can achieve their goal of democracy by 2025 without addressing such issues head-on? Or put that the other way around: what will be left of democracy in 2025 if big data continues to run rampant? Will it be as distant as the gods of Greek mythology? Still not convinced? Read about Amazon secretly removing George Orwell's 1984 and Animal Farm from Kindles while people were reading them, Apple filtering the availability of apps with a pro-Life bias and Facebook using algorithms to identify homosexual users.

Simon McVittie: GNOME Developer Experience hackfest: xdg-app + Debian

Over the last few days I've been at the GNOME Developer Experience hackfest in Brussels, looking into xdg-app and how best to use it in Debian and Debian derivatives. xdg-app is basically a way to run "non-core" software on Linux distributions, analogous to apps on Android and iOS. It doesn't replace distributions like Debian or packaging systems, but it adds a layer above them. It's mostly aimed towards third-party apps obtained from somewhere that isn't your distribution vendor, aiming to address a few long-standing problems in that space: To address the first point, each application uses a specified "runtime", which is available as /usr inside its sandbox. This can be used to run application bundles with multiple, potentially incompatible sets of dependencies within the same desktop environment. A runtime can be updated within its branch - for instance, if an application uses the "GNOME 3.18" runtime (consisting of a basic Linux system, the GNOME 3.18 libraries, other related libraries like Mesa, and their recursive dependencies like libjpeg), it can expect to see minor-version updates from GNOME 3.18.x (including any security updates that might be necessary for the bundled libraries), but not a jump to GNOME 3.20. To address the second issue, the plan is for application bundles to be available as a single file, containing metadata (such as the runtime to use), the app itself, and any dependencies that are not available in the runtime (which the app vendor is responsible for updating if necessary). However, the primary way to distribute and upgrade runtimes and applications is to package them as OSTree repositories, which provide a git-like content-addressed filesystem, with efficient updates using binary deltas. The resulting files are hard-linked into place. To address the last point, application bundles run partially isolated from the wider system, using containerization techniques such as namespaces to prevent direct access to system resources. Resources from outside the sandbox can be accessed via "portal" services, which are responsible for access control; for example, the Documents portal (the only one, so far) displays an "Open" dialog outside the sandbox, then allows the application to access only the selected file. xdg-app for Debian One thing I've been doing at this hackfest is improving the existing Debian/Ubuntu packaging for xdg-app (and its dependencies ostree and libgsystem), aiming to get it into a state where I can upload it to Debian experimental. Because xdg-app aims to be a general freedesktop project, I'm currently intending to make it part of the "Utopia" packaging team alongside projects like D-Bus and polkit, but I'm open to suggestions if people want to co-maintain it elsewhere. In the process of updating xdg-app, I sent various patches to Alex, mostly fixing build and test issues, which are in the new 0.4.8 release. I'd appreciate co-maintainers and further testing for this stuff, particularly ostree: ostree is primarily a whole-OS deployment technology, which isn't a use-case that I've tested, and in particular ostree-grub2 probably doesn't work yet. Source code: Binaries (no trust path, so only use these if you have a test VM): The "Hello, World" of xdg-apps Another thing I set out to do here was to make a runtime and an app out of Debian packages. Most of the test applications in and around GNOME use the "freedesktop" or "GNOME" runtimes, which consist of a Yocto base system and lots of RPMs, are rebuilt from first principles on-demand, and are extensive and capable enough that they make it somewhat non-obvious what's in an app or a runtime. So, here's a step-by-step route through xdg-app, first using typical GNOME instructions, but then using the simplest GUI app I could find - xvt, a small xterm clone. I'm using a Debian testing (stretch) x86_64 virtual machine for all this. xdg-app currently requires systemd-logind to put users and apps in cgroups, either with systemd as pid 1 (systemd-sysv) or systemd-shim and cgmanager; I used the default systemd-sysv. In principle it could work with plain cgmanager, but nobody has contributed that support yet. Demonstrating an existing xdg-app Debian's kernel is currently patched to be able to allow unprivileged users to create user namespaces, but make it runtime-configurable, because there have been various security issues in that feature, making it a security risk for a typical machine (and particularly a server). Hopefully unprivileged user namespaces will soon be secure enough that we can enable them by default, but for now, we have to do one of three things to let xdg-app use them: First, we'll need a runtime. The standard xdg-app tutorial would tell you to download the "GNOME Platform" version 3.18. To do that, you'd add a remote, which is a bit like a git remote, and a bit like an apt repository:
$ wget http://sdk.gnome.org/keys/gnome-sdk.gpg
$ xdg-app remote-add --user --gpg-import=gnome-sdk.gpg gnome \
    http://sdk.gnome.org/repo/
(I'm ignoring considerations like trust paths and security here, for brevity; in real life, you'd want to obtain the signing key via https and/or have a trust path to it, just like you would for a secure-apt signing key.) You can list what's available in a remote:
$ xdg-app remote-ls --user gnome
...
org.freedesktop.Platform
...
org.freedesktop.Platform.Locale.cy
...
org.freedesktop.Sdk
...
org.gnome.Platform
...
The Platform runtimes are what we want here: they are collections of runtime libraries with which you can run an application. The Sdk runtimes add development tools, header files, etc. to be able to compile apps that will be compatible with the Platform. For now, all we want is the GNOME 3.18 platform:
$ xdg-app install --user gnome org.gnome.Platform 3.18
Next, we can install an app that uses it, from Alex Larsson's nightly builds of a subset of GNOME. The server they're on doesn't have a great deal of bandwidth, so be nice :-)
$ wget http://209.132.179.2/keys/nightly.gpg
$ xdg-app remote-add --user --gpg-import=nightly.gpg nightly \
    http://209.132.179.2/repo/
$ xdg-app install --user nightly org.mypaint.MypaintDevel
We now have one app, and the runtime it needs:
$ xdg-app list
org.mypaint.MypaintDevel
$ xdg-app run org.mypaint.MypaintDevel
[you see a GUI window]
Digression: what's in a runtime? Behind the scenes, xdg-app runtimes and apps are both OSTree trees. This means the ostree tool, from the package of the same name, can be used to inspect them.
$ sudo apt install ostree
$ ostree refs --repo ~/.local/share/xdg-app/repo
gnome:runtime/org.gnome.Platform/x86_64/3.18
nightly:app/org.mypaint.MypaintDevel/x86_64/master
A "ref" has roughly the same meaning as in git: something like a branch or a tag. ostree can list the directory tree that it represents:
$ ostree ls --repo ~/.local/share/xdg-app/repo \
    runtime/org.gnome.Platform/x86_64/3.18
d00755 0 0      0 /
-00644 0 0    493 /metadata
d00755 0 0      0 /files
$ ostree ls --repo ~/.local/share/xdg-app/repo \
    runtime/org.gnome.Platform/x86_64/3.18 /files
d00755 0 0      0 /files
l00777 0 0      0 /files/local -> ../var/usrlocal
l00777 0 0      0 /files/sbin -> bin
d00755 0 0      0 /files/bin
d00755 0 0      0 /files/cache
d00755 0 0      0 /files/etc
d00755 0 0      0 /files/games
d00755 0 0      0 /files/include
d00755 0 0      0 /files/lib
d00755 0 0      0 /files/lib64
d00755 0 0      0 /files/libexec
d00755 0 0      0 /files/share
d00755 0 0      0 /files/src
You can see that /files in a runtime is basically a copy of /usr. This is not coincidental: the runtime's /files gets mounted at /usr inside the xdg-app container. There is also some metadata, which is in the ini-like syntax seen in .desktop files:
$ ostree cat --repo ~/.local/share/xdg-app/repo \
    runtime/org.gnome.Platform/x86_64/3.18 /metadata
[Runtime]
name=org.gnome.Platform/x86_64/3.16

[Environment]
GI_TYPELIB_PATH=/app/lib/girepository-1.0
GST_PLUGIN_PATH=/app/lib/gstreamer-1.0
LD_LIBRARY_PATH=/app/lib:/usr/lib/GL
Looking at an app, the situation is fairly similar:
$ ostree ls --repo ~/.local/share/xdg-app/repo \
    app/org.mypaint.MypaintDevel/x86_64/master
d00755 0 0      0 /
-00644 0 0    258 /metadata
d00755 0 0      0 /export
d00755 0 0      0 /files
This time, /files maps to what will become /app for the application, which was compiled with --prefix=/app:
$ ostree ls --repo ~/.local/share/xdg-app/repo \
    app/org.mypaint.MypaintDevel/x86_64/master /files
d00755 0 0      0 /files
-00644 0 0   4599 /files/manifest.json
d00755 0 0      0 /files/bin
d00755 0 0      0 /files/lib
d00755 0 0      0 /files/share
There is also a /export directory, which is made visible to the host system so that the contained app can appear as a "first-class citizen" in menus:
$ ostree ls --repo ~/.local/share/xdg-app/repo \
    app/org.mypaint.MypaintDevel/x86_64/master /export
d00755 0 0      0 /export

Building a runtime, probably the wrong way The way in which the reference/demo runtimes and containers are generated is... involved. As far as I can tell, there's a base OS built using Yocto, and the actual GNOME bits come from RPMs. However, we don't need to go that far to get a working runtime. In preparing this runtime I'm probably completely ignoring some best-practices and tools - but it works, so it's good enough. First we'll need a repository:
$ sudo install -d -o$(id -nu) /srv/xdg-apps
$ ostree init --repo /srv/xdg-apps
I'm just keeping this local for this demonstration, but you could rsync it to a web server's exported directory or something - a lot like a git repository, it's just a collection of files. We want everything in /usr because that's what xdg-app expects, hence usrmerge:
$ sudo mount -t tmpfs -o mode=0755 tmpfs /mnt
$ sudo debootstrap --arch=amd64 --include=libx11-6,usrmerge \
    --variant=minbase stretch /mnt http://192.168.122.1:3142/debian
$ sudo mkdir /mnt/runtime
$ sudo mv /mnt/usr /mnt/runtime/files
This obviously has a lot of stuff in it that we don't need - most obviously init, apt and dpkg - but it's Good Enough . We will also need some metadata. This is sufficient:
$ sudo sh -c 'cat > /mnt/runtime/metadata'
[Runtime]
name=org.debian.Debootstrap/x86_64/8.20160130
runtime=org.debian.Debootstrap/x86_64/8.20160130
That's a runtime. We can commit it to ostree, and generate xdg-app metadata:
$ ostree commit --repo /srv/xdg-apps \
    --branch runtime/org.debian.Debootstrap/x86_64/8.20160130 \
    /mnt/runtime
$ fakeroot ostree commit --repo /srv/xdg-apps \
    --branch runtime/org.debian.Debootstrap/x86_64/8.20160130
$ fakeroot xdg-app build-update-repo /srv/xdg-apps
(I'm not sure why ostree and xdg-app report "Operation not permitted" when we aren't root or fakeroot - feedback welcome.) build-update-repo would presumably also be the right place to GPG-sign your repository, if you were doing that. We can add that as another xdg-app remote:
$ xdg-app remote-add --user --no-gpg-verify local file:///srv/xdg-apps
$ xdg-app remote-ls --user local
org.debian.Debootstrap
Building an app, probably the wrong way The right way to build an app is to build a "SDK" runtime - similar to that platform runtime, but with development files and tools - and recompile the app and any missing libraries with ./configure --prefix=/app && make && make install. I'm not going to do that, because simplicity is nice, and I'm reasonably sure xvt doesn't actually hard-code /usr into the binary:
$ install -d xvt-app/files/bin
$ sudo apt-get --download-only install xvt
$ dpkg-deb --fsys-tarfile /var/cache/apt/archives/xvt_2.1-20.1_amd64.deb \
      tar -xvf - ./usr/bin/xvt
./usr/
./usr/bin/
./usr/bin/xvt
...
$ mv usr xvt-app/files
Again, we'll need metadata, and it's much simpler than the more production-quality GNOME nightly builds:
$ cat > xvt-app/metadata
[Application]
name=org.debian.packages.xvt
runtime=org.debian.Debootstrap/x86_64/8.20160130
command=xvt
[Context]
sockets=x11;
$ fakeroot ostree commit --repo /srv/xdg-apps \
    --branch app/org.debian.packages.xvt/x86_64/2.1-20.1 xvt-app
$ fakeroot xdg-app build-update-repo /srv/xdg-apps
Updating appstream branch
No appstream data for runtime/org.debian.Debootstrap/x86_64/8.20160130
No appstream data for app/org.debian.packages.xvt/x86_64/2.1-20.1
Updating summary
$ xdg-app remote-ls --user local
org.debian.Debootstrap
org.debian.packages.xvt
The obligatory screenshot OK, good, now we can install it:
$ xdg-app install --user local org.debian.Debootstrap 8.20160130
$ xdg-app install --user local org.debian.packages.xvt 2.1-20.1
$ xdg-app run --branch=2.1-20.1 org.debian.packages.xvt
xvt in a container and you can play around with the shell in the xvt and see what you can and can't do in the container. I'm sure there were better ways to do most of this, but I think there's value in having such a simplistic demo to go alongside the various GNOMEish apps.

Norbert Preining: Ian Buruma: Wages of Guilt

Since moving to Japan, I got more and more interested in history, especially the recent history of the 20th century. The book I just finished, Ian Buruma (Wiki, home page) Wages of Guilt Memories of War in Germany and Japan (Independent, NYRB), has been a revelation for me. As an Austrian living in Japan, I am experiencing the discrepancy between these two countries with respect to their treatment of war legacy practically daily, and many of my blog entries revolve around the topic of Japanese non-reconciliation.
Willy Brandt went down on his knees in the Warsaw ghetto, after a functioning democracy had been established in the Federal Republic of Germany, not before. But Japan, shielded from the evil world, has grown into an Oskar Matzerath: opportunistic, stunted, and haunted by demons, which it tries to ignore by burying them in the sand, like Oskar s drum.

Buruma-Wages_of_Guilt The comparison of Germany and Japan with respect to their recent history as laid out in Buruma s book throws a spotlight on various aspects of the psychology of German and Japanese population, while at the same time not falling into the easy trap of explaining everything with difference in the guilt culture. A book of great depth and broad insights everyone having even the slightest interest in these topics should read.
This difference between (West) German and Japanese textbooks is not just a matter of detail; it shows a gap in perception.
Ian Buruma, Wages of Guilt, Romance of the Ruins
Only thinking about giving a halfway full account of this book is something impossible for me. The sheer amount of information, both on the German and Japanese side, is impressive. His incredible background (studies of Chinese literature and Japanese movie!) and long years as journalist, editor, etc, enriches the book with facets normally not available: In particular his knowledge of both the German and Japanese movie history, and the reflection of history in movies, were complete new aspects for me (see my recent post (in Japanese)). The book is comprised of four parts: The first with the chapters War Against the West and Romance of the Ruins; the second with the chapters Auschwitz, Hiroshima, and Nanking; the third with History on Trial, Textbook Resistance, and Memorials, Museums, and Monuments; and the last part with A Normal Country, Two Normal Towns, and Clearing Up the Ruins. Let us look at the chapters in turn: The boook somehow left me with a bleak impression of Japanese post-war times as well as Japanese future. Having read other books about the political ignorance in Japan (Norma Field s In the realm of a dying emperor, or the Chibana history), Buruma s characterization of Japanese politics is striking. He couldn t foresee the recent changes in legislation pushed through by the Abe government actually breaking the constitution, or the rewriting of history currently going on with respect to comfort women and Nanking. But reading his statement about Article Nine of the constitution and looking at the changes in political attitude, I am scared about where Japan is heading to:
The Nanking Massacre, for leftists and many liberals too, is the main symbol of Japanese militarism, supported by the imperial (and imperialist) cult. Which is why it is a keystone of postwar pacifism. Article Nine of the constitution is necessary to avoid another Nanking Massacre. The nationalist right takes the opposite view. To restore the true identity of Japan, the emperor must be reinstated as a religious head of state, and Article Nine must be revised to make Japan a legitimate military power again. For this reason, the Nanking Massacre, or any other example of extreme Japanese aggression, has to be ignored, softened, or denied.
Ian Buruma, Wages of Guilt, Nanking
While there are signs of resistance in the streets of Japan (Okinawa and the Hanako bay, the demonstrations against secrecy law and reversion of the constitution), we are still to see a change influenced by the people in a country ruled and distributed by oligarchs. I don t think there will be another Nanking Massacre in the near future, but Buruma s books shows that we are heading back to a nationalistic regime similar to pre-war times, just covered with a democratic veil to distract critics.
I close with several other quotes from the book that caught my attention: In the preface and introduction:
[ ] mainstream conservatives made a deliberate attempt to distract people s attention from war and politics by concentrating on economic growth.
The curious thing was that much of what attracted Japanese to Germany before the war Prussian authoritarianism, romantic nationalism, pseudo-scientific racialism had lingered in Japan while becoming distinctly unfashionable in Germany.
In Romance of the Ruins:
The point of all this is that Ikeda s promise of riches was the final stage of what came to be known as the reverse course, the turn away from a leftist, pacifist, neutral Japan a Japan that would never again be involved in any wars, that would resist any form of imperialism, that had, in short, turned its back for good on its bloody past. The Double Your Incomes policy was a deliberate ploy to draw public attention away from constitutional issues.
In Hiroshima:
The citizens of Hiroshima were indeed victims, primarily of their own military rulers. But when a local group of peace activists petitioned the city of Hiroshima in 1987 to incorporate the history of Japanese aggression into the Peace Memorial Museum, the request was turned down. The petition for an Aggressors Corner was prompted by junior high school students from Osaka, who had embarrassed Peace Museum officials by asking for an explanation about Japanese responsibility for the war.
The history of the war, or indeed any history, is indeed not what the Hiroshima spirit is about. This is why Auschwitz is the only comparison that is officially condoned. Anything else is too controversial, too much part of the flow of history .
In Nanking, by the governmental pseudo-historian Tanaka:
Unlike in Europe or China, writes Tanaka, you won t find one instance of planned, systematic murder in the entire history of Japan. This is because the Japanese have a different sense of values from the Chinese or the Westerners.
In History on Trial:
In 1950, Becker wrote that few things have done more to hinder true historical self-knowledge in Germany than the war crimes trials. He stuck to this belief. Becker must be taken seriously, for he is not a right-wing apologist for the Nazi past, but an eminent liberal.
There never were any Japanese war crimes trials, nor is there a Japanese Ludwigsburg. This is partly because there was no exact equivalent of the Holocaust. Even though the behavior of Japanese troops was often barbarous, and the psychological consequences of State Shinto and emperor worship were frequently as hysterical as Nazism, Japanese atrocities were part of a military campaign, not a planned genocide of a people that included the country s own citizens. And besides, those aspects of the war that were most revolting and furthest removed from actual combat, such as the medical experiments on human guinea pigs (known as logs ) carried out by Unit 731 in Manchuria, were passed over during the Tokyo trial. The knowledge compiled by the doctors of Unit 731 of freezing experiments, injection of deadly diseases, vivisections, among other things was considered so valuable by the Americans in 1945 that the doctors responsible were allowed to go free in exchange for their data.
Some Japanese have suggested that they should have conducted their own war crimes trials. The historian Hata Ikuhiko thought the Japanese leaders should have been tried according to existing Japanese laws, either in military or in civil courts. The Japanese judges, he believed, might well have been more severe than the Allied tribunal in Tokyo. And the consequences would have been healthier. If found guilty, the spirits of the defendants would not have ended up being enshrined at Yasukuni. The Tokyo trial, he said, purified the crimes of the accused and turned them into martyrs. If they had been tried in domestic courts, there is a good chance the real criminals would have been flushed out.
After it was over, the Nippon Times pointed out the flaws of the trial, but added that the Japanese people must ponder over why it is that there has been such a discrepancy between what they thought and what the rest of the world accepted almost as common knowledge. This is at the root of the tragedy which Japan brought upon herself.
Emperor Hirohito was not Hitler; Hitler was no mere Shrine. But the lethal consequences of the emperor-worshipping system of irresponsibilities did emerge during the Tokyo trial. The savagery of Japanese troops was legitimized, if not driven, by an ideology that did not include a Final Solution but was as racialist as Hider s National Socialism. The Japanese were the Asian Herrenvolk, descended from the gods.
Emperor Hirohito, the shadowy figure who changed after the war from navy uniforms to gray suits, was not personally comparable to Hitler, but his psychological role was remarkably similar.
In fact, MacArthur behaved like a traditional Japanese strongman (and was admired for doing so by many Japanese), using the imperial symbol to enhance his own power. As a result, he hurt the chances of a working Japanese democracy and seriously distorted history. For to keep the emperor in place (he could at least have been made to resign), Hirohito s past had to be freed from any blemish; the symbol had to be, so to speak, cleansed from what had been done in its name.
In Memorials, Museums, and Monuments:
If one disregards, for a moment, the differences in style between Shinto and Christianity, the Yasukuni Shrine, with its relics, its sacred ground, its bronze paeans to noble sacrifice, is not so very different from many European memorials after World War I. By and large, World War II memorials in Europe and the United States (though not the Soviet Union) no longer glorify the sacrifice of the fallen soldier. The sacrificial cult and the romantic elevation of war to a higher spiritual plane no longer seemed appropriate after Auschwitz. The Christian knight, bearing the cross of king and country, was not resurrected. But in Japan, where the war was still truly a war (not a Holocaust), and the symbolism still redolent of religious exultation, such shrines as Yasukuni still carry the torch of nineteenth-century nationalism. Hence the image of the nation owing its restoration to the sacrifice of fallen soldiers.
In A Normal Country:
The mayor received a letter from a Shinto priest in which the priest pointed out that it was un-Japanese to demand any more moral responsibility from the emperor than he had already taken. Had the emperor not demonstrated his deep sorrow every year, on the anniversary of Japan s surrender? Besides, he wrote, it was wrong to have spoken about the emperor in such a manner, even as the entire nation was deeply worried about his health. Then he came to the main point: It is a common error among Christians and people with Western inclinations, including so-called intellectuals, to fail to grasp that Western societies and Japanese society are based on fundamentally different religious concepts . . . Forgetting this premise, they attempt to place a Western structure on a Japanese foundation. I think this kind of mistake explains the demand for the emperor to bear full responsibility.
In Two Normal Towns:
The bust of the man caught my attention, but not because it was in any way unusual; such busts of prominent local figures can be seen everywhere in Japan. This one, however, was particularly grandiose. Smiling across the yard, with a look of deep satisfaction over his many achievements, was Hatazawa Kyoichi. His various functions and titles were inscribed below his bust. He had been an important provincial bureaucrat, a pillar of the sumo wrestling establishment, a member of various Olympic committees, and the recipient of some of the highest honors in Japan. The song engraved on the smooth stone was composed in praise of his rich life. There was just one small gap in Hatazawa s life story as related on his monument: the years from 1941 to 1945 were missing. Yet he had not been idle then, for he was the man in charge of labor at the Hanaoka mines.
In Clearing Up the Ruins:
But the question in American minds was understandable: could one trust a nation whose official spokesmen still refused to admit that their country had been responsible for starting a war? In these Japanese evasions there was something of the petulant child, stamping its foot, shouting that it had done nothing wrong, because everybody did it.
Japan seems at times not so much a nation of twelve-year-olds, to repeat General MacArthur s phrase, as a nation of people longing to be twelve-year-olds, or even younger, to be at that golden age when everything was secure and responsibility and conformity were not yet required.
For General MacArthur was right: in 1945, the Japanese people were political children. Until then, they had been forced into a position of complete submission to a state run by authoritarian bureaucrats and military men, and to a religious cult whose high priest was also formally chief of the armed forces and supreme monarch of the empire.
I saw Jew S ss that same year, at a screening for students of the film academy in Berlin. This showing, too, was followed by a discussion. The students, mostly from western Germany, but some from the east, were in their early twenties. They were dressed in the international uniform of jeans, anoraks, and work shirts. The professor was a man in his forties, a 68er named Karsten Witte. He began the discussion by saying that he wanted the students to concentrate on the aesthetics of the film more than the story. To describe the propaganda, he said, would simply be banal: We all know the what, so let s talk about the how. I thought of my fellow students at the film school in Tokyo more than fifteen years before. How many of them knew the what of the Japanese war in Asia.

Lunar: Reproducible builds: week 36 in Stretch cycle

What happened in the reproducible builds effort between December 27th and January 2nd: Infrastructure dak now silently accepts and discards .buildinfo files (commit 1, 2), thanks to Niels Thykier and Ansgar Burchardt. This was later confirmed as working by Mattia Rizzolo. Packages fixed The following packages have become reproducible due to changes in their build dependencies: banshee-community-extensions, javamail, mono-debugger-libs, python-avro. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them: Untested changes: reproducible.debian.net The testing distribution (the upcoming stretch) is now tested on armhf. (h01ger) Four new armhf build nodes provided by Vagrant Cascandian were integrated in the infrastructer. This allowed for 9 new armhf builder jobs. (h01ger) The RPM-based build system, koji, is now in unstable and testing. (Marek Marczykowski-G recki, Ximin Luo). Package reviews 131 reviews have been removed, 71 added and 53 updated in the previous week. 58 new FTBFS reports were made by Chris Lamb and Chris West. New issues identified this week: nondeterminstic_ordering_in_gsettings_glib_enums_xml, nondeterminstic_output_in_warnings_generated_by_breathe, qt_translate_noop_nondeterminstic_ordering. Misc. Steven Chamberlain explained in length why reproducible cross-building across architectures mattered, and posted results of his tests comparing a stage1 debootstrapped chroot of linux-i386 once done from official Debian packages, the others cross-built from kfreebsd-amd64.

Lunar: Reproducible builds: week 33 in Stretch cycle

What happened in the reproducible builds effort between December 6th and December 12th: Toolchain fixes Reiner Herrmann rebased our experimental version of doxygen on version 1.8.9.1-6. Chris Lamb submitted a patch to make the manpages generated by ruby-ronn reproducible by using the locale-agnostic %Y-%m-%d for the dates. Daniel Kahn Gillmor took another shot at the issue of source path captured in DWARF symbols. A patch has been sent for review by GCC upstream to add the ability to read an environment variable with -fdebug-prefix-map. Packages fixed The following 24 packages have become reproducible due to changes in their build dependencies: gkeyfile-sharp, gprbuild, graphmonkey, gthumb, haskell-yi-language, ion, jackson-databind, jackson-dataformat-smile, jackson-dataformat-xml, jnr-ffi, libcommons-net-java, libproxy, maven-shared-utils, monodevelop-database, mydumper, ndesk-dbus, nini, notify-sharp, pixz, protozero, python-rtslib-fb, slurm-llnl, taglib-sharp, tomboy-latex. The following packages became reproducible after getting fixed: Some uploads fixed some reproducibility issues, but not all of them: These uploads might have fixed reproducibility issues but could not be tested yet: Patches submitted which have not made their way to the archive yet: reproducible.debian.net Files created with diffoscope now have diffoscope in their name instead debbindiff. (h01ger) Hostnames of first and second build node are now recorded and shown in the build history. (Mattia Rizzolo) Exchanges have started with F-Droid developers to better understand what would be required to test F-Droid applications. (h01ger) A first small set of Fedora 23 packages is now also being tested while development on a new framework for testing RPMs in general has begun. A new Jenkins job has been added to set up to mock, the build system used by Fedora. Another new job takes care of testing RPMs from Fedora 23 on x86_64. So far only 151 packages from the buildsys-build group are tested (currently all unreproducible), but the plan is to build all 17,000 source packages in Fedora 23 and rawhide. The page presenting the results should also soon be improved. (h01ger, Dhiru Kholia) For Arch Linux, all 2223 packages from the extra repository will also be tested from now on. Packages in extra" are tested every four weeks, while those from core every week. Statistics are now displayed alongside the results. (h01ger) jenkins.debian.net has been updated to jenkins-job-builder version 1.3.0. Many job configurations have been simplified and refactored using features of the new version. This was another milestone for the jenkins.debian.org migration. (Phil Hands, h01ger) diffoscope development Chris Lamb announced try.diffoscope.org: an online service that runs diffoscope on user provided files. Screenshot of try.diffoscope.org Improvements are welcome. The application is licensed under the AGPLv3. On diffoscope itself, most pending patches have now been merged. Expect a release soon! Most of the code implementing parallel processing has been polished. Sadly, unpacking archive is CPU-bound in most cases, so the current thread-only implementation does not offer much gain on big packages. More work is still require to also add concurrent processes. Documentation update Ximin Luo has started to write a specification for buildinfo files that could become a larger platform than the limited set of features that were thought so far for Debian .buildinfo. Package reviews 113 reviews have been removed, 111 added and 56 updated in the previous week. 42 new FTBFS bugs were opened by Chris Lamb and Niko Tyni. New issues identified this week: timestamps_in_documentation_generated_by_docbook_dbtimestamp, timestamps_in_sym_l_files_generated_by_malaga, timestamps_in_edj_files_generated_by_edje_cc. Misc. Chris Lamb presented reproducible builds at skroutz.gr.

Steve Kemp: I joined the internet of things.

In my old flat I had a couple of simple radio-controlled switches, which allowed me to toggle power to a pair of standing lamps - one at each side of the bed. This was very lazy, but also really handy and I've always been curious about automation.. When it comes to automation there seems to be three main flavours:
X10
The original standard, with stuff produced by many vendors and good Linux support. X10 supports two ways of sending/receiving commands - over the electrical wiring, and over RF.
Z-Wave
This is the newcomer, which despite that seems to be well-supported and extensible. It allows "measurements" to be sent/received in addition to the broadcast of events like "switch on", and "switch off".
Other systems - often lighting-centric
There are toy-things like the previously noted power-controlling things, there are also stand-alone devices from people like Philips with their philips hue system, but given how Philips recently crippled their devices to disable third-party bulbs I've no desire to use them. One company caught my eye though, Osram make a smart lightbulb and mini-hub to work with it.
So I bought one of the osram lightify systems, consisting of a magic box and a pair of lightbulbs. The box connects to your wifi, and gets an IP address. The IP address is then used by the application on your mobile phone (i.e. the magic box does the magic, not the bulbs). The phone application can be used to trigger "on", "off", "dim", "brighter", and the various colour-changing commands, as you would expect. You absolutely must use the phone-based application to do the setup, but after that the whole point was that I could automate things. I wanted to be able to setup my desktop computer to schedule events, and started hacking. I've written a simple Perl module to let me discover bulbs, and turn them off and on. No doubt it'll be on CPAN in the near future, once I can pick a suitable name for it:
$ ol --bridge=192.168.10.136 --list
hall       MAC:8418260000d9c70c RGBW:255,255,255,255 STATE:On
kitchen    MAC:8418260000cb433b RGBW:255,255,255,255 STATE:On
$ ol --bridge=192.168.10.136 --off=kitchen
$ ol --bridge=192.168.10.136 --list
hall       MAC:8418260000d9c70c RGBW:255,255,255,255 STATE:On
kitchen    MAC:8418260000cb433b RGBW:255,255,255,255 STATE:Off
The only niggle was the fiddly pairing, and the lack of any decent documentation. The code I wrote was loosely based on the python project python-lightify written by Mikael Magnusson. Also worth noting that the bridge/magic-box only exposes a single port so you can find the device on your VLAN by nmapping for port 4000:
$ nmap -v 192.168.10.0/24 -p 4000
The device doesn't seem to allow any network setup at all - it only uses DHCP. So you might want to make sure it gets assigned a stable IP. Anyway I'm going to bed. When I do so I'll turn the lights off with my mobile phone. Neat. In the future I will look at more complex automation, and I think Z-wave is the way I'll go. Right now I'm in a rented flat so replacing wall-switches, etc, is something I can't do. But the systems I've looked at seem neat, and this current setup will keep me amused for several months!

Elena 'valhalla' Grandi: Blocked by indiegogo because of blocked javascript?

Blocked by indiegogo because of blocked javascript?

I usually browse the web with javascript blocked, for obvious security reasons and slightly less obvious free software reasons https://www.gnu.org/philosophy/javascript-trap.html, adding sites to a temporary whitelist when absolutely needed.

I know that this hurts the revenue model of many websites, in some cases I'm sorry, in other cases I pay a subscription so that I don't have to be sorry, and in other cases I just don't care, depending on the service they provide.

One thing that I hate are websites that require javascript even to show their basic contents: I understand why some of them are doing it, but less so when they aren't getting money from ads, but from actually providing a paid service, such as indiegogo.

This morning I was browsing a campaign on that crowdfunding site, grudgingly allowed javascript from their domain to be able to see the campaign description and suddenly found this:

Immagine/fotohttp://social.gl-como.it/photo/dde1ddaa79d831ffbc2bee30110a2497.png

So ok, they want me to confirm I'm a human, ok, I'm fine with that, but asking for personal identification? just to be able to browse your site securely? No thanks. The support page linked in that says that this company also support just asking to fill a captcha, which is probably not as effective, but also much less intrusive.

I was browsing a campaign for an (apparently) open hardware encryption device, which is probably enough these days to get you somewhat under the radar (luckily, I am already, and I have a t-shirt to prove it :) ), so being asked to identify myself before I could even start considering whether the device was interesting enough to support (in a public-ish way) was expecially bad.

So, if you are working on something like that, maybe you could consider using a different crowdfunding website, one that respects more their users?

Gunnar Wolf: Scientific resarch and a moral stand should go hand in hand

During the last few days, I found several references to a beautiful just-published paper, which I hope everybody reads: The Moral Character of Cryptographic Work, by Phillip Rogaway; Cryptology ePrint Report 2015/1162, published on December 1st this year. It is more an academic essay than most crypto-related papers, and a long one at that (46 pages, packed with references and anecdotal notes). But it is surprisingly easy to read. I am sitting in front of my computer while my students work on their final exam, and I have got over half way through the text; earlier today I looked at the quick presentation (as this work was presented by Rogaway at the Asiacrypt 2015 as an invited talk), and just loved it. Now, I know most of the people reading my blog have a moral stand on their work (after all, I expect most of you to be committed to Free Software just as I am, and that is a tremendous political statement). We are also more a practice community than an academic/scientific one. But many of us dwell on several projects and hold more than one hats in life through which we are defined. This paper/essay is really clicking with me, and it deeply resonates with the justification I presented when I joined the Masters on Security Engineering and Information Technologies program which I'm halfway through. Computer security does not exist in a void, and does not exist just for itself. As professionals, we have a mission to fulfill in society, and that will then shape how society evolves. So, I invite everybody to at least take a casual look at this paper. I hope you enjoy it as much as I did, and I hope it changes people's hearts and career decisions.

Dirk Eddelbuettel: gtrends 1.3.0 now on CRAN: Google Trends in R

Sometime earlier last year, I started to help Philippe Massicotte with his gtrendsR package---which was then still "hiding" in relatively obscurity on BitBucket. I was able to assist with a few things related to internal data handling as well as package setup and package builds--but the package is really largely Philippe's. But then we both got busy, and it wasn't until this summer at the excellent useR! 2015 conference that we met and concluded that we really should finish the package. And we both remained busy... Lo and behold, following a recent transfer to this GitHub repository, we finalised a number of outstanding issues. And Philippe was even kind enough to label me a co-author. And now the package is on CRAN as of yesterday. So install.packages("gtrendsR") away and enjoy! Here is a quiick demo:
## load the package, and if options() are set appropriately, connect
## alternatively, also run   gconnect("someuser", "somepassword")
library(gtrendsR)
## using the default connection, run a query for three terms
res <- gtrends(c("nhl", "nba", "nfl"))
## plot (in default mode) as time series
plot(res)
## plot via googeVis to browser
## highlighting regions (probably countries) and cities
plot(res, type = "region")
plot(res, type = "cities")
The time series (default) plot for this query came out as follows a couple of days ago:
Example of gtrendsR query and plot
One really nice feature of the package is the rather rich data structure. The result set for the query above is actually stored in the package and can be accessed. It contains a number of components:
R> data(sport_trend)
R> names(sport_trend)
[1] "query"     "meta"      "trend"     "regions"   "topmetros"
[6] "cities"    "searches"  "rising"    "headers"  
R>
So not only can one look at trends, but also at regions, metropolitan areas, and cities --- even plot this easily via package googleVis which is accessed via options in the default plot method. Furthermore, related searches and rising queries may give leads to dynamics within the search. Please use the standard GitHub issue system for bug reports, suggestions and alike.

Matthew Garrett: If it's not practical to redistribute free software, it's not free software in practice

I've previously written about Canonical's obnoxious IP policy and how Mark Shuttleworth admits it's deliberately vague. After spending some time discussing specific examples with Canonical, I've been explicitly told that while Canonical will gladly give me a cost-free trademark license permitting me to redistribute unmodified Ubuntu binaries, they will not tell me what Any redistribution of modified versions of Ubuntu must be approved, certified or provided by Canonical if you are going to associate it with the Trademarks. Otherwise you must remove and replace the Trademarks and will need to recompile the source code to create your own binaries actually means.

Why does this matter? The free software definition requires that you be able to redistribute software to other people in either unmodified or modified form without needing to ask for permission first. This makes it clear that Ubuntu itself isn't free software - distributing the individual binary packages without permission is forbidden, even if they wouldn't contain any infringing trademarks[1]. This is obnoxious, but not inherently toxic. The source packages for Ubuntu could still be free software, making it fairly straightforward to build a free software equivalent.

Unfortunately, while true in theory, this isn't true in practice. The issue here is the apparently simple phrase you must remove and replace the Trademarks and will need to recompile the source code. "Trademarks" is defined later as being the words "Ubuntu", "Kubuntu", "Juju", "Landscape", "Edubuntu" and "Xubuntu" in either textual or logo form. The naive interpretation of this is that you have to remove trademarks where they'd be infringing - for instance, shipping the Ubuntu bootsplash as part of a modified product would almost certainly be clear trademark infringement, so you shouldn't do that. But that's not what the policy actually says. It insists that all trademarks be removed, whether they would embody an infringement or not. If a README says "To build this software under Ubuntu, install the following packages", a literal reading of Canonical's policy would require you to remove or replace the word "Ubuntu" even though failing to do so wouldn't be a trademark infringement. If an @ubuntu.com email address is present in a changelog, you'd have to change it. You wouldn't be able to ship the juju-core package without renaming it and the application within. If this is what the policy means, it's so impractical to be able to rebuild Ubuntu that it's not free software in any meaningful way.

This seems like a pretty ludicrous interpretation, but it's one that Canonical refuse to explicitly rule out. Compare this to Red Hat's requirements around Fedora - if you replace the fedora-logos, fedora-release and fedora-release-notes packages with your own content, you're good. A policy like this satisfies the concerns that Dustin raised over people misrepresenting their products, but still makes it easy for users to distribute modified code to other users. There's nothing whatsoever stopping Canonical from adopting a similarly unambiguous policy.

Mark has repeatedly asserted that attempts to raise this issue are mere FUD, but he won't answer you if you ask him direct questions about this policy and will insist that it's necessary to protect Ubuntu's brand. The reality is that if Debian had had an identical policy in 2004, Ubuntu wouldn't exist. The effort required to strip all Debian trademarks from the source packages would have been immense[2], and this would have had to be repeated for every release. While this policy is in place, nobody's going to be able to take Ubuntu and build something better. It's grotesquely hypocritical, especially when the Ubuntu website still talks about their belief that people should be able to distribute modifications without licensing fees.

All that's required for Canonical to deal with this problem is to follow Fedora's lead and isolate their trademarks in a small set of packages, then tell users that those packages must be replaced if distributing a modified version of Ubuntu. If they're serious about this being a branding issue, they'll do it. And if I'm right that the policy is deliberately obfuscated so Canonical can encourage people to buy licenses, they won't. It's easy for them to prove me wrong, and I'll be delighted if they do. Let's see what happens.

[1] The policy is quite clear on this. If you want to distribute something other than an unmodified Ubuntu image, you have two choices:
  1. Gain approval or certification from Canonical
  2. Remove all trademarks and recompile the source code
Note that option 2 requires you to rebuild even if there are no trademarks to remove.

[2] Especially when every source package contains a directory called "debian"

Norbert Preining: Debian/TeX Live 2015.20151116-1

One month has passed since the big multiarch update, and not one bug report concerning it did come in, that are good news. So here is a completely boring update with nothing more than the usual checkout from the TeX Live tlnet distribution as of yesterday.

Daniel Pocock: How much of Linux will be illegal in the UK?

This week I've been in the UK again, giving a talk about Lumicall and JSCommunicator in Manchester last night and a talk about Free Real-Time Communications at the mini-DebConf in Cambridge on the weekend of 7-8 November. An interesting backdrop to these activities has been a national debate about Internet privacy. The UK Government and police are demanding laws to mandate back doors in all communications products and services. It leaves me wondering about a range of issues:
  • Will overzealous UK police, reknowned for singling out and bullying people who don't conform with their idea of normality, start taking a more sinister attitude to people using software like Linux? For example, if airport security asks to inspect a laptop and doesn't see the familiar Windows or Mac OS desktop, will the owner of the laptop be delayed or told to leave it behind? Some people may feel this is extreme, but workers in these roles are known for taking initiative in their own special way, such as the infamous baby pat-down. If the owner of a Linux laptop is a Muslim, like the Texas schoolboy recently arrested because his clock looks suspicious to the untrained eye of a policeman, the chances of a rough encounter with authority probably rise even further.
  • Will developers still be able to use technologies like PGP and ZRTP in the UK? Will PGP key-signing parties become illegal or have to be held 20 miles offshore on a boat like the legendary pirate radio stations of the sixties?
  • Will Linux distributions such as Debian and Fedora have to avoid distributing packages such as Enigmail?
  • Will updates to Android and iOS on smartphones seek to automatically disable or remove apps like Lumicall?
  • Even if a user chooses a secure app like Lumicall for communication, will the vendor of the operating system be required to provide alternative ways to monitor the user, for example, by intercepting audio before it is encrypted by the app?
  • Without strong encryption algorithms, digital signatures will no longer be possible either and it will be impossible for software vendors to securely distribute new versions of their software.
  • Why should the police be the only workers to have their job done for them by Internet snooping? Why shouldn't spouses have a right to all their partner's communications to periodically verify they are not cheating and putting themselves at risk of diseases? Why shouldn't employers be able to check on employee's private communications and home computers to help prevent leaks of customer data? Why shouldn't the NHS be able to go through people's garbage to monitor what they eat given the WHO warning that bacon is more likely to kill you than a terrorist?
  • While the authorities moan about the internet being a "safe" place for terrorists and paedophiles, what is their real motivation for trying to bring in these new laws, even when their best technical advisors must surely be telling them about the risks and negative consequences for compatibility of UK systems in a global Internet? If the terrorist scare story is not so credible, is it more likely they are seeking to snoop on people who may not be paying taxes or to maintain the upper hand over rival political parties like the Greens and the UKIP in a time of prolonged and increasingly punitive austerity?
  • Australia already introduced similar laws a few weeks ago, despite widespread criticism from around the world. With cricket and rugby now over, is the UK just looking to go one up on Australia in the game of snooping?
Island mentality in the Internet age Politics aside, what would this mean from a technical perspective? The overwhelming consensus among experts is that secure technology that people use and expect in many other parts of the world, including the US, simply won't be compatible with the products and services that UK residents will be permitted to use. Bigger companies like Google and Apple may be able to offer differentiated versions of their services for the UK but smaller companies or companies who have built their reputation on technical excellence simply won't be able or willing to offer crippled versions of their products with backdoors for the UK. The UK's island geography will become a metaphor for its relationship with the global marketplace. The first thing to take note of is that encryption and authentication are closely related. Public-key cryptography, for example, simply swaps the public key and private key when being used to authenticate instead of encrypt. An effective and wide-reaching legal ban on encryption would also potentially prohibit the algorithms used for authentication. Many methods of distributing software, including packages distributed through Linux distributions or apps distributed through the Google Play store are authenticated with such algorithms. This is often referred to as a digital signature. Digital signatures help ensure that software is not corrupted, tampered with by hackers or infected by viruses when it is transmitted and stored in the public Internet. To correctly implement these mechanisms for installing software safely, every device running an operating system such as Debian, Ubuntu, Fedora or Android needs to include some software modules implementing the algorithms. In Linux, for example, I'm referring to packages like GnuPG, OpenSSL and GnuTLS. Without these components, it would be hard or even impossible for developers in the UK to contribute or publish new versions of their software. Users of the software would not be able to securely receive vital updates to their systems. An opportunity for free software? Some people say that any publicity can be good publicity. Now the Government has put the ball into play, people promoting secure solutions based on free software have an opportunity to participate in the debate too. While laws may or may not change, principles don't. It is a perfect time to remind users that many of the principles of software freedom were written down many years ago, before the opportunity for mass surveillance came into existence. These principles remain relevant to this day. The experts who developed these principles back then are also far more likely to offer insights and trustworthy solutions for the road ahead. If you'd like to discuss these issues or ask questions, please join the Free-RTC mailing list.

Russ Allbery: Vacation book haul

Reading on vacation always puts me in the mood to buy more books, including a couple that I picked up while on vacation. (I only read one, but that one, Ancillary Mercy, was certainly worth it.) Ta-Nehisi Coates Between the World and Me (non-fiction)
Kameron Hurley Empire Ascendant (sff)
Kameron Hurley Rapture (sff)
Jenny Lawson Furiously Happy (non-fiction)
Ann Leckie Ancillary Mercy (sff)
Kaori Mori Bride's Story: Volume 2 (graphic novel)
Kaori Mori Bride's Story: Volume 3 (graphic novel)
Randall Munroe xkcd: Volume 0 (strip collection)
Jo Walton The Philosopher Kings (sff)
Fumi Yoshinaga oku: Volume 3 (graphic novel) Infidel, the middle book of the Bel Dame Apocrypha trilogy by Kameron Hurley, was out of stock, so I'll have to re-order. I might put in another book order shortly to get that plus a few other things, although really I could just take that time to go read more books. Back from vacation now, so fell out of the reading habit a bit. I've been doing other stuff on the train, but shortly I'll get back into it.

Pau Garcia i Quiles: FOSDEM Desktops DevRoom 2016

It is now official: KDE will be present again at FOSDEM in the 2016 edition, on the 30th and 31st of January, 2016. Talks will take place at the Desktops DevRoom, on Sunday the 31st, but not exclusively: in past years, there were Qt and KDE-related talks at the mobile devroom, lightning talks, distributions, open document editors and more. KDE will be sharing the room with other desktop environments, as usual: Gnome, Unity, Enlightenment, Razor, etc. Representatives from those communities will be helping me in managing and organizing the devroom: Christophe Fergeau, Michael Zanetti, Philippe Caseiro and J rome Leclanche. I would like to extend the invitation to any other free/open source desktop environment and/or related stuff. Check last year s schedule for an example. Closed-source shops (Microsoft, Apple, Oracle, etc) are ALSO invited, provided that you will talk about something related to open source. We will publish the Call for Talks for the Desktops DevRoom 2016 soon. Stay tuned. In the meanwhile, you can subscribe to the Desktops DevRoom mailing list to be informed of important and useful information, and talk about FOSDEM and specific issues of the Desktops DevRoom.

Daniel Pocock: A mission statement for free real-time communications

At FOSDEM 2013, the RTC panel in the main track used the tag line "Can we finally replace Skype, Viber, Twitter and Facebook?" Does replacing something else have the right ring to it though? Or does such a goal create a negative impression? Even worse, does the term Skype replacement fall short of being a mission statement that gives people direction and sets expectations of what we would actually like to replace it with? Towards a clearer definition Lets consider what a positive statement might look like:
Making it as easy as possible to make calls to other people and to receive calls from other people for somebody who chooses only to use genuinely Free Software, open standards, a free choice of service providers and a credible standard of privacy.
If you agree with this or if you feel you can propose a more precise statement, please come and share your thoughts on the Free RTC email list. The value of a mission statement should not be underestimated. With the right mission statement, it should be possible to envision what the future will look like if we succeed and also if we don't. With the vision of success in mind, it should be easier for developers and the wider free software community to identify the steps that must be taken to make progress.

Russ Allbery: Review: The Oathbound

Review: The Oathbound, by Mercedes Lackey
Series: Vows and Honor #1
Publisher: DAW
Copyright: July 1988
ISBN: 0-88677-414-4
Format: Mass market
Pages: 302
This book warrants a bit of explanation. Before Arrows of the Queen, before Valdemar (at least in terms of publication dates), came Tarma and Kethry short stories. I don't know if they were always intended to be set in the same world as Valdemar; if not, they were quickly included. But they came from another part of the world and a slightly different sub-genre. While the first two Valdemar trilogies were largely coming-of-age fantasy, Tarma and Kethry are itinerant sword-and-sorcery adventures featuring two women with a soul bond: the conventionally attractive, aristocratic mage Kethry, and the celibate, goddess-sworn swordswoman Tarma. Their first story was published, appropriately, in Marion Zimmer Bradley's Swords and Sorceress III. This is the first book about Tarma and Kethry. It's a fix-up novel: shorter stories, bridged and re-edited, and glued together with some additional material. And it does not contain the first Tarma and Kethry story. As mentioned in my earlier Valdemar reviews, this is a re-read, but it's been something like twenty years since I previously read the whole Valdemar corpus (as it was at the time; I'll probably re-read everything I have on hand, but it's grown considerably, and I may not chase down the rest of it). One of the things I'd forgotten is how oddly, from a novel reader's perspective, the Tarma and Kethry stories were collected. Knowing what I know now about publishing, I assume Swords and Sorceress III was still in print at the time The Oathbound was published, or the rights weren't available for some other reason, so their first story had to be omitted. Whatever the reason, The Oathbound starts with a jarring gap that's no less irritating in this re-read than it was originally. Also as is becoming typical for this series, I remembered a lot more world-building and character development than is actually present in at least this first book. In this case, I strongly suspect most of that characterization is in Oathbreakers, which I remember as being more of a coherent single story and less of a fix-up of puzzle and adventure stories with scant time for character growth. I'll be able to test my memory shortly. What we do get is Kethry's reconciliation of her past, a brief look at the Shin'a'in and the depth of Tarma and Kethry's mutual oath (unfortunately told more than shown), the introduction of Warrl (again, a relationship that will grow a great deal more depth later), and then some typical sword and sorcery episodes: a locked room mystery, a caravan guard adventure about which I'll have more to say later, and two rather unpleasant encounters with a demon. The material is bridged enough that it has a vague novel-like shape, but the bones of the underlying short stories are pretty obvious. One can tell this isn't really a novel even without the tell of a narrative recap in later chapters of events that you'd just read earlier in the same book. What we also get is rather a lot of rape, and one episode of seriously unpleasant "justice." A drawback of early Lackey is that her villains are pure evil. My not entirely trustworthy memory tells me that this moderates over time, but early stories tend to feature villains completely devoid of redeeming qualities. In this book alone one gets to choose between the rapist pedophile, the rapist lord, the rapist bandit, and the rapist demon who had been doing extensive research in Jack Chalker novels. You'll notice a theme. Most of the rape happens off camera, but I was still thoroughly sick of it by the end of the book. This was already a cliched motivation tactic when these stories were written. Worse, as with the end of Arrow's Flight, the protagonists don't seem to be above a bit of "turnabout is fair play." When you're dealing with rape as a primary plot motivation, that goes about as badly as you might expect. The final episode here involves a confrontation that Tarma and Kethry brought entirely on themselves through some rather despicable actions, and from which they should have taken a lesson about why civilized societies have criminal justice systems. Unfortunately, despite an ethical priest who is mostly played for mild amusement, no one in the book seems to have drawn that rather obvious conclusion. This, too, I recall as getting better as the series goes along and Lackey matures as a writer, but that only helps marginally with the early books. Some time after the publication of The Oathbound and Oathbreakers, something (presumably the rights situation) changed. Oathblood was published in 1998 and includes not only the first Tarma and Kethry story but also several of the short stories that make up this book, in (I assume) something closer to their original form. That makes The Oathbound somewhat pointless and entirely skippable. I re-read it first because that's how I first approached the series many years ago, and (to be honest) because I'd forgotten how much was reprinted in Oathblood. I'd advise a new reader to skip it entirely, start with the short stories in Oathblood, and then read Oathbreakers before reading the final novella. You'd miss the demon stories, but that's probably for the best. I'm complaining a lot about this book, but that's partly from familiarity. If you can stomach the rape and one stunningly unethical protagonist decision, the stories that make it up are solid and enjoyable, and the dynamic between Tarma and Kethry is always a lot of fun (and gets even better when Warrl is added to the mix). I think my favorite was the locked room mystery. It's significantly spoiled by knowing the ending, and it has little deeper significance, but it's a classic sort unembellished, unapologetic sword-and-sorcery tale that's hard to come by in books. But since it too is reprinted (in a better form) in Oathblood, there's no point in reading it here. Followed by Oathbreakers. Rating: 6 out of 10
