The C1 ServerScaleway started selling ARM based hosted server in April. I've intended to blog about this for a while, since it was time to upgrade from wheezy to jessie was timely, why not switch provider from an X86 based to ARM one at the same time? In many ways scaleway node is opposite to what "Enterprise ARM" people are working on. Each server is based on an oldish ARMv7 Quad-Core Marvell Armada XP, instead of a brand new 64-bit ARMv8 cpu. There is no UEFI, ACPI or any other "industry standards" involved, just a smooth web interface and a command line tool to manage your node(s). And the node is yours, it's not shared with others with virtualization. The picture above is a single node, which is stacked with 911 other nodes into a single rack. This week, the C1 price was dropped to a very reasonable 2.99 per month, or 0.006 per hour. Software runs on hardware, news at 11The performance is more than enough for my needs - shell, email and light web serving. dovecot, postfix, irssi and apache2 are just an apt-get away. Anyone who says you need x86 for Linux servers is forgetting that Linux software is open source, and if not already available, can be compiled to any architecture with little effort. Thus the migration pains were only because I chose to modernize configuration of dovecot and friends. Details of the new setup shall be left for another post.

I just noticed that SSLLabs now supports IPv6. I could not find an announcement for it but I'd guess it's already there for some time. There is also a new sslscan release in experimental with IPv6 support. Thanks to Marvin and formorer who finally made that happen. Update: Since this won't hit official backports.d.o soon I've done a pbuilder build for jessie.

Common Lisp users are very happy to use Quicklisp when it comes to downloading and maintaining dependencies between their own code and the librairies it is using. Sometimes I am pointed that when compared to other programming languages Common Lisp is lacking a lot in the batteries included area. After having had to package about 50 common lisp librairies for debian I can tell you that I politely disagree with that. And this post is about the tool and process I use to maintain all those librairies. Quicklisp is good at ensuring a proper distribution of all those libs it supports and actually tests that they all compile and load together, so I've been using it as my upstream for debian packaging purposes. Using Quicklisp here makes my life much simpler as I can grovel through its metadata and automate most of the maintenance of my cl related packages. It's all automated in the ql-to-deb software which, unsurprisingly, has been written in Common Lisp itself. It's a kind of a Quicklisp client that will fetch Quicklisp current list of releases with version numbers and compare to the list of managed packages for debian in order to then build new version automatically. The current workflow I'm using begins with using ql-to-deb is to check for the work to be done today:

$ /vagrant/build/bin/ql-to-deb check
Fetching "http://beta.quicklisp.org/dist/quicklisp.txt"

Quite simple. To be totally honnest, I first had a problem with the parser generator library esrap wherein the README documentation changed to be a README.org file, and I had to tell my debian packaging about that. See the 0ef669579cf7c07280eae7fe6f61f1bd664d337e commit to ql-to-deb for details. What about trying to install those packages locally? That's usually a very good test. Sometimes some dependencies are missing at the dpkg command line, so another apt-get install -f is needed:

$ /vagrant/build/bin/ql-to-deb install

All looks fine, time to sign those packages. There's a trick here, where you want to be sure you're using a GnuPG setup that allows you to enter your passphrase only once, see ql-to-deb vm setup for details, and the usual documentations about all that if you're interested into the details.

Of course the same text or abouts is then repeated for all the other packages. Enjoy using Common Lisp in debian! Oh and remember, the only reason I've written ql-to-deb and signed myself up to maintain those upteens Common Lisp librairies as debian package is to be able to properly package pgloader in debian, as you can see at https://packages.debian.org/sid/pgloader and in particular in the Other Packages Related to pgloader section of the debian source package for pgloader at https://packages.debian.org/source/sid/pgloader. That level of effort is done to ensure that we respect the Debian Social Contract wherein debian ensures its users that it's possible to rebuild anything from sources as found in the debian repositories.

As it is nearly time to release Debian 8 (codename jessie), I've uploaded a new version of the Linux kernel to unstable which I hope will be the version to go into the initial release (8.0). The changes from the current version in testing are mostly bug fixes:

• Many fixes from stable releases 3.16.7-ckt8 and 3.16.7-ckt9
• New hardware support: early console support on various systems, Xen MCE log, power control on some Allwinner (sunxi) systems, FocalTech PS/2 touchpads
• Security fixes: CVE-2014-8159, CVE-2014-9710, CVE-2015-0275, CVE-2015-2666, CVE-2015-2922
• Fix for data corruption on some Marvell Armada SoCs
• Require upgraded flash-kernel on Kirkwood systems to avoid boot failure
• Use the right fan control drivers on G5 PowerMac
• Fix two instances of boot console noise on x86 (#781953, #781418)
• Fix WARNING when attaching some display devices to i915 GPU
• Fix race condition in thingm driver
• Hide eMMC RPMB partitions which userland doesn't need to see and which often cause hangs
• On 32-bit PowerPC, package the radeonfb module (formerly built-in) for inclusion in the installer

Please test this new version (which should be on mirrors within the next 24 hours) and report any regressions you spot. It's now too late to add new hardware support for Debian 8.0, but we'll probably be able to improve it in subsequent point releases. So, please also report driver changes that should be backported from later kernel versions to improve hardware support, with severity of 'important'. If you can provide precise information about which upstream commits are needed, that makes things easier for us, and you should add the 'patch' tag.

Attention: rant coming. You have been warned, and may want to tune out now. So the top of my Twitter timeline just had a re-tweet posting to this marvel on the state of Julia. I should have known better than to glance at it as it comes from someone providing (as per the side-bar) Thought leadership in Big Data, systems architecture and more. Reading something like this violates the first rule of airport book stores: never touch anything from the business school section, especially on (wait for it) leadership or, worse yet, thought leadership. But it is Sunday, my first cup of coffee still warm (after finalising two R package updates on GitHub, and one upload to CRAN) and so I read on. Only to be mildly appalled by the usual comparison to R based on the same old Fibonacci sequence. Look, I am as guilty as anyone of using it (for example all over chapter one of my Rcpp book), but at least I try to stress each and every time that this is kicking R where it is down as its (fairly) poor performance on functions calls (that is well-known and documented) obviously gets aggravated by recursive calls. But hey, for the record, let me restate those results. So Julia beats R by a factor of 385. But let's take a closer look. For n=25, I get R to take 241 milliseconds---as opposed to his 6905 milliseconds---simply by using the same function I use in every workshop, eg last used at Penn in November, which does not use the dreaded ifelse operator:

fibR <- function(n)  
  if (n < 2) return(n)
  return(fibR(n-1) + fibR(n-2))
 

Switching that to the standard C++ three-liner using Rcpp

library(Rcpp)
cppFunction('int fibCpp(int n)   
  if (n < 2) return(n);  
  return(fibCpp(n-1) + fibCpp(n-2));  
   ')

and running a standard benchmark suite gets us the usual result of

R> library(rbenchmark)
R> benchmark(fibR(25),fibCpp(25),order="relative")[,1:4]
        test replications elapsed relative
2 fibCpp(25)          100   0.048    1.000
1   fibR(25)          100  24.674  514.042
R> 

So for the record as we need this later: that is 48 milliseconds for 100 replications, or about 0.48 milliseconds per run. Now Julia. And of my standard Ubuntu server running the current release 14.10:

edd@max:~$ julia
ERROR: could not open file /home/edd//home/edd//etc/julia/juliarc.jl
 in include at boot.jl:238
edd@max:~$ 

So wait, what? You guys can't even ensure a working release on what is probably the most popular and common Linux installation? And I get to that after reading a post on the importance of "Community, Community, Community" and you can't even make sure this works on Ubuntu? Really? So a little bit of googling later, I see that julia -f is my friend for this flawed release, and I can try to replicate the original timing

edd@max:~$ julia -f

Interestingly the posts author claims 18 milliseconds. I see 2.3 milliseconds here. Maybe someone is having a hard time comparing things to the right of the decimal point. Or maybe his computer is an order of magnitude slower than mine. The more important thing is that Julia is of course faster than R (no surprise: LLVM at work) but also still a lot slower than a (trivial to write and deploy) C++ function. Nothing new here. So let's recap. Comparison to R was based on a flawed version of a function we only use when we deliberately want to put R down, can be improved significantly when using a better implementation, results are still off by order of magnitude to what was reported ("math is hard"), and the standard C / C++ way of doing things is still several times faster than our new saviour language---which I can't even launch on the current version of one of the more common free operating systems. Ok then. Someone please wake me up in a few years and I will try again. Now, coming to the end of the rant I should really stress that of course I too hope that Julia succeeds. Every user pulled away from Matlab is a win for all us. We're in this together and the endless navel gazing between ourselves is so tiresome and irrelevant. And as I argue here, even more so when we among ourselves stick to unfair comparisons as well as badly chosen implementation details. What matters are wins against the likes of Matlab, Excel, SAS and so on. Let's build on our joint strength. I am sure I will use Julia one day, and I am grateful for everyone helping with it---as a lot of help seems to be needed. In the meantime, and with CRAN at 6130 packages that just work I'll continue to make use of this amazing community and trying my bit to help it grow and prosper. As part of our joint community.

• The Memory Palace: This is the way history should be taught, but rarely is. Nate DiMeo takes past events and puts you in the middle of them, in a way that makes you emphathise so much with people from the past. Each episode is a little short story, and they're often only a few minutes long. A great example is this description of when Niagra falls stopped. I have listened to the entire back archive, and want more. Only downside is it's a looong time between new episodes.
• The Haskell Cast: Panel discussion with a guest, there is a lot of expertise amoung them and I'm often scrambling to keep up with the barrage of ideas. If this seems too tame, check out The Type Theory Podcast instead..
• Benjamen Walker's Theory of Everything: Only caught 2 episodes so far, but they've both been great. Short, punchy, quirky, geeky. Astoundingly good production values.
• Lightspeed magazine and Escape Pod blur together for me. Both feature 20-50 minute science fiction short stories, and occasionally other genre fictions. They seem to get all the award-winning short stories. I sometimes fall asleep to these which can make for strange dreams. Two strongly contrasting examples: "Observations About Eggs from the Man Sitting Next to Me on a Flight from Chicago, Illinois to Cedar Rapids, Iowa" and "Pay Phobetor"
• Serial: You probably already know about this high profile TAL spinoff. If you didn't before: You're welcome. :) Nuff said.
• Redecentralize: Interviews with creators of decentralized internet tools like Tahoe-LAFS, Ethereum, Media Goblin, TeleHash. I just wish it went into more depth on protocols and how they work.
• Love and Radio: This American Life squared and on acid.
• Debian & Stuff: My friend Asheesh and that guy I ate Thai food with once in Portland in a marvelously unfocused podcast that somehow connects everything up in the end. Only one episode so far; what are you guys waiting on? :P
• Hacker Public Radio: Anyone can upload an episode, and multiple episodes are published each week, which makes this a grab bag to pick and choose from occasionally. While mostly about Linux and Free Software, the best episodes are those that veer var afield, such as the 40 minute river swim recording featured in Wildswimming in France.

Also, out of the podcasts I listed previously, I still listen to and enjoy Free As In Freedom, Off the Hook, and the Long Now Seminars. PS: A nice podcatcher, for the technically inclined is git-annex importfeed. Featuring list of feeds in a text file, and distributed podcatching!

I find it somewhat interesting that thousands of years later that our society still uses Publilius Syrus sententiae though I imagine the tendency to leave well enough alone means such phrases stay in usage.

One weekend Steve McIntyre asked me if I could find a source of some of some 40mm fans for some systems with some pretty strict requirements. They needed to be long life and shift a lot of air to combat a persistent overheating issue.

I sat with him and went through the Farnell utterly hateful parametric web interface and eventually came up with a couple of options which were very expensive. Only then did I stop and ask what the actual problem was.

Steve showed me one of the Debian ARM buildd boxes which are Marvell development machines. These systems are powerful quad core machines housed in compact steel enclosures.

There is a single 40mm fan trying to provide cooling for the entire enclosure. When the units are placed horizontally and used intermittently this proves adequate. Unfortunately when the system are arranged vertically in a rack and run at full load continuously they often overheat and have to be restarted. In addition the small high speed fans need replacing frequently as their bearings wore out quickly.

This was obviously causing some issues for the ARM Debian ports which Steve wanted to rectify. After talking the problem through for a while we came to the conclusion we could use much larger 60mm fans to blow air directly through the top of the case onto the cpu heatsink.

Larger fans can be run much more slowly to move a similar volume of air to the smaller 40mm fans which gives a much longer service life.

Steve proceeded to order enough parts to allow us to modify all the Debian systems, this worked out cheaper than a single "special" 40mm high volume fan.

I acquired a rather large steel hole punch, I chose this tool because it produces a much superior finish to a hole cutter and this project demanded a high level of finish (not to mention I loved having a valid excuse to own and use a huge allen key!)

If we had simply been modifying a single case I would have measured and marked up by hand. With the prospect of altering at least eight I laser cut a template from plywood which Andy Simpkins took great glee in excessively annotating.

We also used the opportunity to add bolt holes to securely attach the 2.5 inch SATA drives instead of using sticky pads.

Steve and I modified a single system to begin with both to check our alignment and the efficacy of the change. We were pleasantly surprised to discover that hoiby could now repeatedly do kernel compiles with all four cores flat out which was not possible before. The measured CPU temperature, which had previously been around 90 C, did not rise above 40 C

Steve, Andy and I then arranged a day where we took all the remaining units out of the rack at ARM, modified and returned them. We used the facilities at the Cambridge Makespace where I am a member to do the modifications.

I broke two 3mm drill bits and dulled a 4mm bit drilling all the holes, Roger Smith was good enough to loan us the use of his "Christmas tree bit" to ream the fan hole out to 16mm so we could thread the hole punch and cut the 60mm fan aperture out.

We managed to get quite an assembly line going and, in my opinion, the results look pretty professional.

It has been several months since we did this work and these systems continue to run without issue. To complete the story we can see some graphs courtesy of the DSA munin instance.

You can clearly see the huge drop in temperature at the end of Week 25 despite the continuously high CPU load. Also there is only a single gap in the data after the changes (these indicate crashes where data was not recorded) where before there were frequent and extensive times where the systems were simply unusable.

One reason I continue to enjoy Debian so much is the wide variety of ways in which I can contribute not only by maintaining my packages. Sometimes this kind of work does not receive the credit it deserves and hopefully highlights a small part of the frantic paddling that goes on under the serene surface of the Debian project to keep things "just working".

Debian has recently received a donation of 8 build machines from Marvell. The new machines come with Quad core MV78460 Armada XP CPU's, DDR3 DIMM slot so we can plug in more memory, and speedy sata ports. They replace the well served Marvell MV78200 based builders - ones that have been building debian armel since 2009. We are planning a more detailed announcement, but I'll provide a quick summary: The speed increase provided by MV78460 can viewed by comparing build times on selected builds since early april: Qemu build times. We can now build Qemu in 2h instead of 16h -8x faster than before! Certainly a substantial improvement, so impressive kit from Marvell! But not all packages gain this amount of speedup: webkitgtk build times. This example, webkitgtk, builds barely 3x faster. The explanation is found from debian/rules of webkitgkt:

# Parallel builds are unstable, see #714072 and #722520
# ifneq (,$(filter parallel=%,$(DEB_BUILD_OPTIONS)))
#   NUMJOBS = $(patsubst parallel=%,%,$(filter parallel=%,$(DEB_BUILD_OPTIONS)))
#   MAKEARGUMENTS += -j$(NUMJOBS)
# endif

The old builders are single-core[1], so the regardless of parallel building, you can easily max out the cpu. New builders will use only 1 of 4 cores without parallel build support in debian/rules. During this buildd cpu usage graph, we see most time only one CPU is consumed. So for fast package build times.. make sure your packages supports parallel building. For developers, abel.debian.org is porter machine with Armada XP. It has schroot's for both armel and armhf. set "DEB_BUILD_OPTIONS=parallel=4" and off you go. Finally I'd like to thank Thomas Petazzoni, Maen Suleiman, Hector Oron, Steve McIntyre, Adam Conrad and Jon Ward for making the upgrade happen. Meanwhile, we have unrelated trouble - a bunch of disks have broken within a few days apart. I take the warranty just run out... [1] only from Linux's point of view. - mv78200 has actually 2 cores, just not SMP or coherent. You could run an RTOS on the other core while you run Linux on the other.

Wow. 3G delta. I haven t booted this laptop for a while I think I m finally ready to make the move from gnome2 to gnome3. There are bits that still annoy me, but I think it s off to a good start. Upgrading perl from 5.10 to 5.14.

Keeping your DVD collection safe from scratches and curious children fingers while still having it available when you want to see a movie is not straight forward. My preferred method at the moment is to store a full copy of the ISO on a hard drive, and use VLC, Popcorn Hour or other useful players to view the resulting file. This way the subtitles and bonus material are still available and using the ISO is just like inserting the original DVD record in the DVD player. Earlier I used dd for taking security copies, but it do not handle DVDs giving read errors (which are quite a few of them). I've also tried using dvdbackup and genisoimage, but these days I use the marvellous python library and program python-dvdvideo written by Bastian Blank. It is in Debian already and the binary package name is python3-dvdvideo. Instead of trying to read every block from the DVD, it parses the file structure and figure out which block on the DVD is actually in used, and only read those blocks from the DVD. This work surprisingly well, and I have been able to almost backup my entire DVD collection using this method. So far, python-dvdvideo have failed on between 10 and 20 DVDs, which is a small fraction of my collection. The most common problem is DVDs using UTF-16 instead of UTF-8 characters, which according to Bastian is against the DVD specification (and seem to cause some players to fail too). A rarer problem is what seem to be inconsistent DVD structures, as the python library claim there is a overlap between objects. An equally rare problem claim some value is out of range. No idea what is going on there. I wish I knew enough about the DVD format to fix these, to ensure my movie collection will stay with me in the future. So, if you need to keep your DVDs safe, back them up using python-dvdvideo. :)

I have written a number of scripts to create Debian foreign architecture (mostly armel and armhf) rootfs images for SD cards or NAND flashing. I started with putting Debian on my Openmoko gta01 and gta02 and continued with devices like the qi nanonote, a marvel kirkwood based device, the Always Innovating Touchbook (close to the Beagleboard), the Notion Ink Adam and most recently the Golden Delicious gta04. Once it has been manufactured, I will surely also get my hands dirty with the Neo900 whose creators are currently looking for potential donors/customers to increase the size of the first batch and get the price per unit further down. Creating a Debian rootfs disk image for all these devices basically follows the same steps:

1. create an disk image file, partition it, format the partitions and mount the / partition into a directory
2. use debootstrap or multistrap to extract a selection of armel or armhf packages into the directory
3. copy over /usr/bin/qemu-arm-static for qemu user mode emulation
4. chroot into the directory to execute package maintainer scripts with dpkg --configure -a
5. copy the disk image onto the sd card

It was not long until I started wondering why I had to run all of the above steps with superuser privileges even though everything except the final step (which I will not cover here) was in principle nothing else than writing some magic bytes to files I had write access to (the disk image file) in some more or less fancy ways. So I tried using fakeroot+fakechroot and after some initial troubles I managed to build a foreign architecture rootfs without needing root priviliges for steps two, three and four. I wrote about my solution which still included some workarounds in another article here. These workarounds were soon not needed anymore as upstream fixed the outstanding issues. As a result I wrote the polystrap tool which combines multistrap, fakeroot, fakechroot and qemu user mode emulation. Recently I managed to integrate proot support in a separate branch of polystrap. Last year I got the LEGO ev3 robot for christmas and since it runs Linux I also wanted to put Debian on it by following the instructions given by the ev3dev project. Even though ev3dev calls itself a "distribution" it only deviates from pure Debian by its kernel, some configuration options and its initial package selection. Otherwise it's vanilla Debian. The project also supplies some multistrap based scripts which create the rootfs and then partition and populate an SD card. All of this is of course done as the superuser. While the creation of the file/directory structure of the foreign Debian armel rootfs can by now easily be done without superuser priviliges by running multistrap under fakeroot/fakechroot/proot, creating the SD card image still seems to be a bit more tricky. While it is no problem to write a partition table to a regular file, it turned out to be tricky to mount these partition because tools like kpartx and losetup require superuser permissions. Tools like mkfs.ext3 and fuse-ext2 which otherwise would be able to work on a regular file without superuser privileges do not seem to allow to specify the required offsets that the partitions have within the disk image. With fuseloop there exists a tool which allows to "loop-mount" parts of a file in userspace to a new file and thus allows tools like mkfs.ext3 and fuse-ext2 to work as they normally do. But fuseloop is not packaged for Debian yet and thus also not in the current Debian stable. An obvious workaround would be to create and fill each partition in a separate file and concatenate them together. But why do I have to write my data twice just because I do not want to become the superuser? Even worse: because parted refuses to write a partition table to a file which is too small to hold the specified partitions, one spends twice the disk space of the final image: the image with the partition table plus the image with the main partition's content. So lets summarize: a bootable foreign architecture SD card disk image is nothing else than a regular file representing the contents of the SD card as a block device. This disk image is created in my home directory and given enough free disk space there is nothing stopping me from writing any possible permutation of bits to that file. Obviously I'm interested in a permutation representing a valid partition table and file systems with sensible content. Why do I need superuser privileges to generate such a sensible permutation of bits? Gladly it seems that the (at least in my opinion) hardest part of faking chroot and executing foreign architecture package maintainer scripts is already possible without superuser privileges by using fakeroot and fakechroot or proot together with qemu user mode emulation. But then there is still the blocker of creating the disk image itself through some user mode loop mounting of a filesystem occupying a virtual "partition" in the disk image. Why has all this only become available so very recently and still requires a number of workarounds to fully work in userspace? There exists a surprising amount of scripts which wrap debootstrap/multistrap. Most of them require superuser privileges. Does everybody just accept that they have to put a sudo in front of every invocation and hope for the best? While this might be okay for well tested code like debootstrap and multistrap the countless wrapper scripts might accidentally (be it a bug in the code or a typo in the given command line arguments) write to your primary hard disk instead of your SD card. Such behavior can easily be mitigated by not executing any such script with superuser privileges in the first place. Operations like loop mounting affect the whole system. Why do I have to touch anything outside of my home directory (/dev/loop in this case) to populate a file in it with some meaningful bits? Virtualization is no option because every virtualization solution again requires root privileges. One might argue that a number of solutions just require some initial setup by root to then later be used by a regular user (for example /etc/fstab configuration or the schroot approach). But then again: why do I have to write anything outside of my home directory (even if it is only once) to be able to write something meaningful to a file in it? The latter approach also does not work if one cannot become root in the first place or is limited by a virtualized environment. Imagine you are trying to build a Debian rootfs on a machine where you just have a regular user account. Or a situation I was recently in: I had a virtual server which denied me operations like loop mounting. Given all these downsides, why is it still so common to just assume that one is able and willing to use sudo and be done with it in most cases? I really wonder why technologies like fakeroot and fakechroot have only been developed this late. Has this problem not been around since the earliest days of Linux/Unix? Am I missing something and rambling around for nothing? Is this idea a lost cause or something that is worth spending time and energy on to extend and fix the required tools?

Today I link you to a video narrated by the legendary Carl Sagan The Frontier is Everywhere. Partial quotes:

We were hunters and foragers. The frontier was everywhere. We were bounded only by the earth, and the ocean, and the sky. The open road still softly calls. Our little terraqueous globe as the madhouse of those hundred thousand millions of worlds. We, who cannot even put our own planetary home in order, riven with rivalries and hatreds; are we to venture out into space? By the time we are ready to settle even the nearest other planetary systems, we will have changed For all our failings, despite our limitations and fallibilities, we humans are capable of greatness How far will our nomadic species have wandered, by the end of the next century, and the next millennium? Our remote descendants, safely arrayed on many worlds through the solar system, and beyond, will be unified, by their common heritage, by their regard for their home planet, and by the knowledge that, whatever other life may be, the only humans in all the universe, come from Earth. They will gaze up and strain to find the blue dot in their skies. They will marvel at how vulnerable the repository of all our potential once was, how perilous our infancy, how humble our beginnings, how many rivers we had to cross, before we found our way.

Can you imagine seeing Earthrise? Incredible.

There will come a time when you believe everything is finished. That will be the beginning. Louis L Amour

Last year, I wrote about the difficult times in my life and hope for future, but never really explained why. I have written little since, because there is little I can write without a bit of explanation. It is partly because of the complexity of the task of telling my story without telling too much of others stories. But it is important I tell this story. So often on the Internet, we hear only the brave face, the positive things that happen. This story involves tears and difficulty. And also we often see only anger and bitterness. This story involves joy and celebration. One afternoon last year, I was working as usual (I work from home) when two sheriff deputies arrived on my doorstep. They gave me paperwork showing that my now ex-wife had filed for divorce, had asked them to serve me the paperwork, and that she had been given temporary possession of the house. I had 2 hours to gather up clothes and a little computer equipment (there was a list) and leave the house. Thus began the most difficult time in my life. I went from reading a bedtime story and singing a bedtime song to my young boys every night to seeing them only a little, from living in the house my grandparents and dad had lived in to having no particular plan for where I d sleep that night, from thinking I had a good idea of what the future held to not knowing when, if ever, I d ever be back home. I worried about how the boys would fare (they have done well so far). And it was incomprehensible; I couldn t find answers to why? . In the time since, the divorce became final, I did return home, the boys spend more time with me, and a new normal emerged. At the time, it seemed like a sudden, deep winter blizzard. I couldn t see very far down the road, spring seemed far off, and I couldn t see very well either forward or backward. But I was determined to find positives in the situation. It started almost immediately; I had never been a person to talk about pain, but just a few hours after the divorce was filed, I knew I needed to talk to someone about it, and did. A week later, I shared about it in church. Amazing friends, locally and all over the world, provided support and encouragement. I had less total time with the boys than before the divorce, but more time with just the three of us, and we used it to play together at home, spend days in town, and even take a train trip to Santa Fe, where none of us had ever been before. I realized how much I could forgive, and that my ex-wife probably did the best she could with the persistent legacy of difficult life events that happened to her long before she met me. I understood this, and was never angry, just sad, for everyone. I have always known nobody is perfect, myself included, but can be hard on myself when I m less than perfect. I forgave myself, too, realizing that I did my best to help in the most unfamiliar of waters, and although I sometimes didn t get it right, my conscience is clear because my heart was in the right place and I tried, very hard. Most incredibly, I became a person with a deep sense of inner peace. I always tried to work hard to set life on a good path; I got good grades in school, am a good employee, and have a strong set of values. But where courts are involved, there s a strong sense of powerlessness. At times, there was nothing I could do to make life better for my boys or for me. I finally had to let go of taking on responsibility for all that on my own shoulders. I simply knew that things would be OK, and in fact were OK, and that there is nothing in life that really deserves worries. That doesn t mean worries are never present, but that mostly they are subdued, like a radio quietly playing in another room. When they aren t, I can sit down at the piano, play my penny whistle, sing, walk to my creek, talk to friends, or any of so many things that let them melt away. I stopped searching for happiness and peace, and let those things find me. In religious terms, my faith became not just an intellectual one, but also a spiritual one. An atheist friend asked me, Just what does religion mean to you anyway? My answer: The certainty that spring always comes, for everyone that understands this.

People speak of misfortunes and sufferings, remarked Pierre, but if at this moment I were asked: Would you rather be what you were before you were taken prisoner, or go through all this again? then for heaven s sake let me again have captivity and horseflesh! We imagine that when we are thrown out of our usual ruts all is lost, but it is only then that what is new and good begins. While there is life there is happiness. There is much, much before us. Tolstoy, War and Peace

By Thanksgiving, I had much to be thankful for. Some of it under my nose waiting to be rediscovered after years of distraction, such as the glorious Kansas sunrises. Some things were new, such as roasting a turkey all by myself (or, rather, with Jacob and Oliver) for the first time, and having it come out absolutely perfectly. And some were just the things of everyday life: that I lived in my own house again, that I could walk out to the creek at the edge of my property whenever I wanted, that I could play piano, that the sounds of laughter and little running feet again could often be heard on my wood floors. That s not to say everything was easy; the courts sometimes made decisions sometimes I didn t think were in the boys best interests, legal things dragged on and on, but in the end, peace endured. Happiness endured. I found myself thinking at Thanksgiving that it was the best Thanksgiving ever. Not much later, I considered myself happier than I ve ever been. I was focusing on the daily gifts of life, marveling at the sunrises, looking forward to life s next adventure, confident that it would be far better than the last. And then, to my complete surprise, I found myself in a relationship again. On top of all the wonderful things happening in my life, I met Laura. I never could have imagined a friend so wonderful, a relationship so loving and joyful, something to treasure so deeply. I can look back at events and shake my head in amazement and wonder, that I found myself happier than I d ever been, and then this wonderful relationship on top of that. I have been blessed to have the life I do, and feel almost embarrassingly lucky. I share this story because friends that had been through divorce years ago shared their stories. They gave me hope. And if I didn t share this story in this public way, I would be squandering an opportunity to find more positives from what happened. I hope that this helps, somehow, someone that is in pain know that there is beauty in the valley, and spring always comes, every single year. And I share it because happiness like this can t be repressed for long. Tolstoy was right. While there is life, there is happiness. I ll end with a story from last Thanksgiving. It was 6:10AM that weekend. I was still asleep, and heard this: Jacob, yelling from his room: Dad? Dad! Me, groggy: Yes, Jacob? Jacob: Can I go down and look at the Christmas tree? Me: Sure, and you can turn it on too. Jacob: Great! At that point, I could have gone back to sleep. I was really short on sleep that morning, and Jacob would have been fine. But I gave him a couple of minutes, then I went downstairs too. He was curled up on the piano bench, looking at the tree. I quietly turned up the downstairs thermostat, got a chair, put it next to the piano bench, and sat down by the tree too. Jacob crawled over onto my lap and snuggled up for awhile. Neither of us said anything. Then: Dad? Yes? This is the best Thanksgiving ever. And he gave me a big hug. And he was right. Yes, he was RIGHT! That will be the beginning. Spring comes!

I found the following news item; if you can read Spanish, you will most probably prefer the original version in the Proceso magazine's site. The subject? The federal police (PGR) and army arrest 17 artisans for making money out of Spiderman. The following translation is mine. Done past midnight, and being quite tired, and translated so this news item can reach a broader audience. All errors are mine (except those carried out by the security forces, that is).

June 13, 2013 Cuernavaca, Morelos. Policement from the General Republic Attorney (Procuradur a General de la Rep blica, PGR) and the Army entered and searched the "3 de mayo" neighbourhood, in the municipality of Emiliano Zapata, detaining 17 ceramist artisans that sold candies, dolls and pi atas shaped like Spiderman. This search was done on the evening of last Wednesday, around 16:00. Federal ministerial policement and army soldiers closed a street with several informal stores and detained workers taht were selling this Marvel Comics character, following said company's denounce. As a result for this operation, 17 artisants were detained, although the same day five of them were freed. The policemen also seized 12 bags of candies, pi atas, ceramics and wooden figures of the superhero. PGR closed down 11 stores where ceramics with this same figure was being sold, accusing the detainees of plagiarizing Spiderman's image, protected under the copyright law. The 12 that remained under detention were put at the Federal Justice's disposal, which prompted that this Thursday, around 10AM, hundreds of sellers of "3 de mayo" went out to PGR's building to demand their friends' freedom, who are facing a bail of up to 200,000 pesos (~USD$18,000). Outraged because they said they were treated as if they were part of a drug ring, hundreds of artisans closed intermitently Avenida Cuauhn huac, where the PGR representation in Morelos state is located. The artisans' pressure helped for the amount of the bail to be lowered from MX$200,000 to MX$16,000, and so they were set free. Francisco Fern ndez Flores, president of the Ceramists Association, criticized the operation because, he said, it was as strong as if they were "drug dealers". The artisans explained that they don't even make the Spiderman figures, they are made by the interns of the Centro Estatal de Reinserci n Social de Atlacholoaya (prision), located in the Xochitepec municipality, who offered them to the ceramists so they could be sold. "The Atlacholoaya inmates do them, we buy them to support them, and turns out we are the delinquents now", said Miriam Monroy, sister of one of the detainees. This information was contradicted by Jes s Valencia Valencia, responsible for Morelos' state prision system, who assured that in said prision no ceramics are done. Fern ndez Flores insisted though that from within the prision they are being offered pi atas, candies and "piggy banks" with Spiderman's shape. Jos Luis Pozo, vicepresident of the Ceramists Union, said that to avoid more such federal operations for copyright breaches, they have committed not to produce or commercialize Marvel superhero figures, and any other characters the authority demands. "We do commit to, from now on, those products singled out to us will not be commercialized", he said. Pozo said that the PGR operation caused losses not just to the detained producers and salesmen, but to over 200 ceramists that had to close their stores in solidarity with their friends. Acording to the artisans, the products were a success until the PGR came, seized the products and detained the salesmen.

And yes, the copyright insanity does not stop. Spiderman is by today a clear part of popular culture. Marvel brilliantly succeeded in creating such a popular icon that everybody recognizes, that everybody identifies with And that everybody should be able to recreate. We are not talking about brand protection. Marvel does not, and will never, commercialize pi atas, ceramics or wooden toys. And even if they were plastic-cast While Spiderman is still under the protection of copyright, as the Berne Convention defines it (and of course, as the much stricter Mexican laws agree), that does not mean that any and every product resembling a Spiderman should be protected. Many ceramists and pi ata makers will create unique pieces of art Ok, handicraft. But reading the copyright law more strictly, Spiderman is more treated as a trademark than as a copyright. And it is a trademark that should be declared as having passed on to the public domain.

In January, I announced a new IRC channel #debian-lego, for those of us in the Debian and Linux community interested in LEGO, the marvellous construction system from Denmark. We also created a wiki page to have a place to take notes and write down our plans and hopes. And several people showed up to help. I was very happy to see the effect of my call. Since the small start, we have a debtags tag hardware::hobby:lego tag for LEGO related packages, and now count 10 packages related to LEGO and Mindstorms:

brickos	alternative OS for LEGO Mindstorms RCX. Supports development in C/C++
leocad	virtual brick CAD software
libnxt	utility library for talking to the LEGO Mindstorms NX
lnpd	daemon for LNP communication with BrickOS
nbc	compiler for LEGO Mindstorms NXT bricks
nqc	Not Quite C compiler for LEGO Mindstorms RCX
python-nxt	python driver/interface/wrapper for the Lego Mindstorms NXT robot
python-nxt-filer	simple GUI to manage files on a LEGO Mindstorms NXT
scratch	easy to use programming environment for ages 8 and up
t2n	simple command-line tool for Lego NXT

Some of these are available in Wheezy, and all but one are currently available in Jessie/testing. leocad is so far only available in experimental. If you care about LEGO in Debian, please join us on IRC and help adding the rest of the great free software tools available on Linux for LEGO designers.

Online tech news site Ars Technica (which I recommend, by the way) recently reviewed the Dell XPS 13 Developer Edition. Its unique feature: it ships with Ubuntu Linux as the default operating system. This preload deal had a few unique properties:

• It s from a major system vendor, not a no-name or third-party integrator.
• It s a desktop-oriented product, not a server.
• Most notably, the vendor actually put effort into making it work well.

That last point deserves some explanation. A few vendors have grabbed a Windows computer they sell and allowed the option to preload Linux on it, but without support; you re on your own if it doesn t work in some way, which is likely. Essentially, they save you the time of wiping Windows off the box and doing a fresh install, but not much more. But this laptop comes out of Dell s Project Sputnik, a project to put out Linux machines for developers with a DevOps flavor, and they felt the machine had to work as well as their regular products. So they actually put effort and testing into getting the laptop to run Ubuntu well, with all the drivers configured properly and tweaked to support the machine s quirks, just like they do for Windows. And so, the review is surprised to learn that Ubuntu on the XPS 13, well, just works! It s even in the title of the review. Here s reviewer Lee Hutchinson s observations:

I ve struggled before with using Linux as my full-time operating environment both at work and at home. I did it for years at work, but it was never quite as easy as I wanted it to be on an older Dell laptop, keeping dual monitor support working correctly across updates required endless fiddling with xorg.conf, and whether or not it was Nvidia s fault was totally irrelevant to swearing, cursing Past Lee, trying desperately to get his monitors to display images so he could make his 10am conference call without having to resort to running the meeting on the small laptop screen.

And thence comes the astonishment: on this Linux laptop, everything just works. Most of the review is spent on the kinds of hardware features that distinguish this from other laptops: the keyboard is like this, the screen is that resolution, it has this CPU and this much RAM and so on. Some space is devoted to impressions of the default Ubuntu 12.04 install, and some space is given to the special DevOps software, which helps the developer reproduce the software environment on the laptop when deploying apps. But before all that, Hutchinson has to put in a dig:

It s an impressive achievement, and it s also a sad comment on the overall viability of Linux as a consumer-facing operating system for normal people. I don t think anyone is arguing that Linux hasn t earned its place in the data center it most certainly has but there s no way I d feel comfy installing even newbie-friendly Ubuntu or Mint on my parents computers. The XPS 13 DE shows the level of functionality and polish possible with extra effort, and that effort and polish together means this kind of Linux integration is something we won t see very often outside of boutique OEMs.

Of course, Windows is actually worse than Linux on the hardware front when you don t get it pre-installed. Imagine if more vendors put as much effort into preinstalled Linux as they did into preinstalled Windows. In that alternate reality, I imagine people would react more like this:

Isn t that what you re looking for in a mainstream product? Rick chided. In 1996 it was: Wow look at this, I got Linux running on xxxxxxxx. Even in 2006 that was at times an accomplishment When was the last time you turned on an Apple or Windows machine and marveled that it just worked? It should be boring.

Which was, of course, the reaction Hutchinson got when discussing the review with a Linux-using friend. With Microsoft being less of a friend to the hardware vendors every day, here s a case study more of them should be paying attention to.

God hates people that are I heard a sentence that began that way on an interview with a protestor outside the Supreme Court yesterday. It is a deeply sad, and deeply wrong, statement. If someone reads the Bible, and can come up with a word, any word, that completes that sentence, they re doing it wrong. If someone thinks that there is anyone God hates, then I have this to say: No. Just no. I saw an article today, taking pages and pages to assess what the Christian response to gay marriage should be. I don t need pages. It s very simple. It s this: God is the God of love. That is all. Where people are doing good, there is God. Where people care about each other, there is God. Where there are flowers blooming and trees shading and birds singing, there is God. Where people marvel in the beauty of the landscape or of another person, there is God. And where people love, there is God. There is too much hate in the world already. Instead of adding more, let s celebrate compassion, devotion, and peace. People that say that God is the God of hate look at the spring landscape and see only last year s thistles. One day soon, I hope to see everyone s hearts set free. What a day of joy that will be! And I hope, too, that those that hate will find the peace of freed hearts, freed from hate and from fear.

The problem with Samsung laptops bricking themselves turned out to be down to the UEFI variable store becoming more than 50% full and Samsung's firmware being dreadful, but the trigger was us writing a crash dump to the nvram. I ended up using this feature to help someone get a backtrace from a kernel oops during suspend today, and realised that it's not been terribly well publicised, so.

First, make sure pstore is mounted. If you're on 3.9 then do:

mount -t pstore /sys/fs/pstore /sys/fs/pstore

For earlier kernels you'll need to find somewhere else to stick it. If there's anything in there, delete it - we want to make sure there's enough space to save future dumps. Now reboot twice[1]. Next time you get a system crash that doesn't make it to system logs, mount pstore again and (with luck) there'll be a bunch of files there. For tedious reasons these need to be assembled in reverse order (part 12 comes before part 11, and so on) but you should have a crash log. Report that, delete the files again and marvel at the benefits that technology has brought to your life.

[1] UEFI implementations generally handle variable deletion by flagging the space as reclaimable rather than immediately making it available again. You need to reboot in order for the firmware to garbage collect it. Some firmware seems to require two reboot cycles to do this properly. Thanks, firmware.

It has been so very long since I have left a trace here. I guess moving to two new countries (Canada and Quebec), starting a new job, working on Anonymous, and finishing my first book was a bit much. I miss this space, not so much because what I write here is any good. But it a handy way for me to keep track of time and what I do and even think. My life feels like a blur at times and hopefully here I can see its rhythms and changes a little more clearly if I occasionally jot things down here. So I thought it would nice to start with something that I found surprising: famed information designer, Edward Tufte, a professor emeritus at Yale was a phone phreak (and there is a stellar new book on the topic by former phreak Phil Lapsley. He spoke about his technological exploration during a sad event, a memorial service in NYC which I attended for the hacker and activist Aaron Swartz. I had my wonderful RA transcribe the speech, so here it is [we may not have the right spelling for some of the individuals so please let us know of any mistakes]:

Edward Tufte s Speech From Aaron Swartz s Memorial
Speech starts 41:00 [video cuts out in beginning]
We would then meet over the years for a long talk every now and then, and my responsibility was to provide him with a reading list, a reading list for life and then about two years ago Quinn had Aaron come to Connecticut and he told me about the four and a half million downloads of scholarly articles and my first question is, Why isn t MIT celebrating this? .
[Video cuts out again]
Obviously helpful in my career there, he then became president of the Mellon foundation, he then retired from the Mellon foundation, but he was asked by the Mellon foundation to handle the problem of JSTOR and Aaron. So I wrote Bill Bullen(sp?) an email about it, I said first that Aaron was a treasure and then I told a personal story about how I had done some illegal hacking and been caught at it and what happened. In 1962, my housemate and I invented the first blue box, that s a device that allows for free, undetectable, unbillable long distance telephone calls. And we got this up and played around with it and the end of our research came when we concluded what was the longest long distance call ever made, which was from Palo Alto to New York time-of-day via Hawaii, well during our experimentation, AT&T, on the second day it turned out, had tapped our phone and uh but it wasn t until about 6 months later when I got a call from the gentleman, AJ Dodge, senior security person at AT&T and I said, I know what you re calling about. and so we met and he said You what you are doing is a crime that would , you know all that. But I knew it wasn t serious because he actually cared about the kind of engineering stuff and complained that the tone signals we were generating were not the standard because they record them and play them back in the network to see what numbers they we were that you were trying to reach, but they couldn t break though the noise of our signal. The upshot of it was that uh oh and he asked why we went off the air after about 3 months, because this was to make long distance telephone calls for free and I said this was because we regarded it as an engineering problem and we made the longest long distance call and so that was it. So the deal was, as I explained in my email to Bill Bullen, that we wouldn t try to sell this and we were told, I was told that crime significance would pay a great deal for this, we wouldn t do any more of it and that we would turn our equipment over to AT&T, and so they got a complete vacuum tube isolator kit for making long distance phone calls. But I was grateful for AJ Dodge and I must say, AT&T that they decided not to wreck my life. And so I told Bill Bullen that he had a great opportunity here, to not wreck somebody s life, course he thankfully did the right thing.
Aaron s unique quality was that he was marvelously and vigorously different. There is a scarcity of that. Perhaps we can be all a little more different too.
Thank you very much.

The Debian package of the Linux kernel is based on Linux 3.2, but has some additional features. This continues from parts 1, 2 and 3, and covers new and improved hardware support. DRM drivers from Linux 3.4 (proposed) Some recent Intel and AMD graphics chips were not supported well or at all by the DRM (Direct Rendering Manager) drivers in Linux 3.2. Although many bug fixes have been included in 3.2.y stable updates, we are considering updating them to the versions found in Linux 3.4. (We did something similar for Debian 6.0 'squeeze'.) Julien Cristau has been working on this and has prepared binary packages. To install, run as root:

gpg --no-default-keyring --keyring /usr/share/keyrings/debian-keyring.gpg --export 310180050905E40C   apt-key add -
echo deb http://people.debian.org/~jcristau/wheezy-drm34/ ./ > /etc/apt/sources.list.d/jcristau-wheezy-drm34.list
apt-get update
apt-get install linux-image-3.2.0-4.drm-amd64  # or -486, or -686-pae

Please test these and report your results to bug #687442. I would suggest testing suspend/resume (if applicable), use of internal and external displays on laptops, and 3D accelerated graphics (games and compositing window managers such as GNOME Shell). Remember that AMD/ATI graphics chips require the firmware from the firmware-linux-nonfree package for 3D acceleration and many other features. amilo-rfkill driver I wrote a standard rfkill driver for the Fujitsu-Siemens Amilo A1655 and M7440, based on the out-of-tree fsaa1655g and fsam7440 drivers. Unlike those, it should work with the rfkill command, Network Manager, etc. ALPS touchpads Newer touchpads made by ALPS use different protocols for reporting scroll and pinch gestures. Jonathan Nieder backported the changes to support these. Wacom tablets Jonathan Nieder updated the wacom driver to the version in Linux 3.5, adding support for the Intuos5, Bamboo Connect, Bamboo 16FG and various other models. Emulex OneConnect 'Skyhawk' Sarveshwar Bandi at Emulex contributed a backport of the be2net driver from Linux 3.5, adding support for their 'Skyhawk' chip. Marvell Kirkwood Marvell's Kirkwood SoCs have been supported upstream for some time and in Debian since release 6.0 'squeeze'. However new models and boards generally require specific support. Arnaud Patard backported support for the 6282 rev A1 chip found in QNAP TS-x19P II models, and for the Marvell Dreamplug and Iomega Iconnect. Miscellaneous

• ITE IT8728F hardware monitor
• Ralink RT5392, RT5390R and RF5372 wifi chips
• Synaptics USB touchpad devices
• JMicron JM362 SATA controller
• IguanaWorks USB IR transceiver

More to come Missing hardware support is an important bug that can be fixed by kernel updates during a freeze and throughout the lifetime of a stable release. If you know that new hardware isn't supported by the Debian kernel, please open a bug report. I can't promise that it will be fixed, but we need to know what's missing. Hardware vendors that maintain their own drivers upstream (not out-of-tree) are especially welcome to contribute tested backports that add support for the latest hardware. Send mail to debian-kernel@lists.debian.org if you have any questions about this.
