After finally being able to fix Debian bug #794266 I want to thank those who made this possible: Some time ago my colleague Bj rn offered an Arietta G25 to me. After Jochen, another colleague, helped me to solder pin headers on it, this machine served as host computer for my tests. As I didn't have a machine with the relevant RTC chip, I contacted Seiko Instruments and they provided me a few chips including oscillators. It was again Jochen who then created a break-out board from these components that I could wire to my Arietta board. Finally Wolfram Sang's i2ctransfer helped me a lot to access and so understand the chip. It's has not landed in i2c-tools.git, but I hope this will change soon given that this is a really useful tool. A big thank you to all who helped me. It was fun and would have been less so without your efforts!

A week has gone by and another small sharing about Doha and one package that quite a few of us use everyday but don t think much of them. Let s start with Doha with these two pictures which tells/shares a bit about what the Doha of today is like While I have more than a dozen snapshots of Doha, all of them show same thing, all are huge skyscrapers and overall Doha seems to be aping Dubai and is in a frenzy as World Cup 2022 is around the corner. We did see a few of the older places but these seemed to be more done for tourists rather than the real thing. We saw stuff like This was a picture taken by Ritesh Raj Saraff, a friend and a DD whom I met while I was going to Debconf. The place where this picture has been taken is known as a Souk or what we know as market-place. This was a place where you could get spices. Quite a few of the spices that we get and use in India were bought from Middle-East in the olden times. In fact, it has been argued that the whole Mughlai food that is part of Indian culture was imported from Middle-East when we were trading them before India or Akhand Bharat was invaded. What was interesting to both of us is that we could perceive that most of the buildings had a sort of fakeness to it, they tried to show that it had a lot of detailed work on the buildings but we could see it was all done recently so not that old as being led to believe. One of the other interesting bits that we came to know throughout our stay in Qatar that almost 80-90% of the staff we met inside Qatar airport as well as in the Souk were people from Asian sub-continent and more specifically from South India. I had few interesting conversations with some of the people who were managing the shops were that almost of them were just employees while the owners were Qataris . I could understand this as the distance and flight between Qatar and India is hardly 3 hours. It seemed very similar to how Mexicans look for work in United States. The most expensive thing there was water as it s desert other than housing and most workers seemed to have shared accommodation from anywhere between 5-15 people in one room. It s only the relative strength of the Qatari Rial which probably compels them to be there. The temperature was around 45 degrees with a bit of humidity as it s next to the Ocean. For all the money in the world, I wouldn t work there. It is true that you know your city s worth only when you go outside I do have some more stories about Qatar but that would have to wait for another day now. Also, I really don t want to talk much about this part as it s part depressing but probably would explore it a bit in a further blog-post. One of the more interesting topics that I attended was the apt talk . There are 3-4 tools in the Debian world i.e. apt, aptitude, apt-get, dpkg and dselect. More often than not people know aptitude and apt-get whereas the rest of the packages are not thought so much about. What I somewhat suspected about the history of apt was revealed to be true today, courtesy David K. You can see the talk/video about apt at http://meetings-archive.debian.net/pub/debian-meetings/2016/debconf16/The_past_year_in_APT.webm. I had been curious about apt,libapt,dpkg and the entire tool-chain which goes into updating packages and like. I had a couple of conversations here in India before on mail, in person and IRC as well as couple of conversations in South Africa as well before the APT talk where it was told that packages are not signed or it s not easy to figure out the integrity. Being a Debian fan-boy I could not believe this to be true. Hence I asked and to my dismay found it to be true . I also then asked the same with a bit more background on the mailing list as well and got to know that this has been a concern since 2005. As I do not have the requisite skills and the person would require probably knowledge of dpkg internals as well as have probably good social skills to have at least 1-2 DD s help her/im to work on it and have probably some server space where even some partial archive is re-built using debian packages which use dpkg-sig . I also had some concerns that even if somebody did do the work, it might come in the way of the reproducible builds concept where Neils shared ways in which it could be overcome. Having said the above, it is totally doable if somebody has the will, skills and the patience to do it. Just look at the amazing work done by the team which re-built almost all the archive using clang. See clang.debian.net for the amazing work that they have done. Now, one of the issues in India which comes in popularizing Debian or in fact any free software distribution in India is the bandwidth issue or rather the lack of it or how expensive it is. The situation for better lack of term is pathetic . While nothing can be done till the time the Govt. gives limited term oligopoly licenses to telecom operators and they have a cabal (cabal closed team where decisions and policies are made without any knowledge of and to other stakeholders.) we need to find ways to make the best of the situation. Anyways, while there are some ideas to tackle that but that s a long-term goal and I will share some aspects of it in probably another blog post. In the interim somethings can definitely be made better. Now one of the issues that is there for most people is getting the package updates. Before updating the packages, the package index needs to be updated. Now, both in home and work environments most people are cautious to update the package index. But many times, either due to bandwidth issues or some other issue which is outside your control, your package index is corrupted. I have put both the possible reasons of why and how the package index corruption takes place and a probable work-around of in the deity mail post. I do hope to put in a more coherent state by probably making smaller bug issues so they could be tackled or answered one by one. Any improvements would be better for stability of debian infrastructure only. If anybody does do the required work and need a guinea pig for testing, count me in. Just holler and share you will be working on this aspect and at least one of my workstations would definitely take part in seeing if its better or not. Even if you are able to just provide a way to make a copy of /var/lib/apt/lists after every successful update and do the comparison with time-stamp on next run and only change the copy when a successful update occurs, that will be a huge help in itself. Look forward to hearing form one and all.

This is a repost and update of my retirement letter sent privately to Debian last month, July 10, 2016. At that time I received many notes of appreciation and good wishes which I treasure. Now, I d like to say goodbye to the broader Debian community and, as well, indicate which of the cleanup items have since been addressed in strikethrough style and with annotations. Also, I d like to stay in touch with many of you, so I have added some comments oriented towards those of you who are interested in doing that after the letter.

When in 1995, on a tip from a friend, I installed Debian on my 386 at work and was enthralled with the results, I could not have foreseen that two years later, friends I had made on channel #debian would nudge me to become a Debian developer. Nor when that happened did I have any idea that twenty years later, I d consider Debian to be like family, the greatest free software community in the world, and would still be promoting it and helping people with it whenever I could. Debian quietly, unexpectedly became a part of what defines me. My priorities in life have changed over that time, though. I have shifted my attention to things that are more important to me in life, such as my family, my health and well-being physically and spiritually, and bringing all I can to bear on the task of preserving our local wilderness areas and trails. In the latter area, I m now bringing all of what Debian has helped shaped me to be to the table, launching some ambitious projects I hope will bear fruit in the coming years, and make a measurable contribution to help us hang onto our precious natural preserves where I live. Unfortunately, as I ve poured more time and energy into these things, I ve increasingly not been giving my packages the care they need. Nor do I have any roles or goals now for any of the Debian projects I was previously involved in. So, after much careful deliberation, and as much as it pains me to say it, it s time to retire as a Debian developer. It has been a great privilege to work with you, and to meet many of you in New York at Debconf 10. I plan to be around online, and will continue to take an interest in Debian, lending a hand when I can. Thanks for all of the fun times, for all that I ve learned, and for the privilege to make awesome things with you. I ll treasure this forever. So much for the soppy bits. Now, business. These things remain to clean up upon my departure, and I d appreciate help from QA, and anyone else who can lend a hand. My packages are effectively orphaned, but I haven t the time to do any of the cleanup myself, so please speak up if you can help.

1. Debian Jr.
   • O: junior-doc. The junior-doc package has been awaiting an overhaul by whoever revives the project since I gave it up years ago. I m still listed as maintainer and that should be changed to Debian Junior Maintainers <debianjr-maintainers@lists.alioth.debian.org> if they want it. Otherwise, it is orphaned.
   • I should also be dropped from Uploaders from debian-junior, the metapackages source. Fixed in git.
2. Tux Paint. This is a very special package that deserves to go to someone who will love it and care for it well. There are three source packages in all:
   • O: tuxpaint
   • O: tuxpaint-config
   • O: tuxpaint-stamps
3. O: xletters. This is a cute little typing practice game and needs a new maintainer.
4. XPilot is co-maintained by Phil Brooke <pjb@debian.org>, so he should replace me as Maintainer. Phil said he ll pick up xpilot-ng and will also look at xpilot-extra.
   • xpilot-ng
   • O: xpilot-extra (recently removed from testing due to my neglect, and not co-maintained by Phil; it s unclear if anyone really uses this anymore)
5. GTypist is co-maintained by Daniel Leidert <dleidert@debian.org> and should replace me as Maintainer.
6. My ruby packages. A group of packages that I brought into Debian as dependencies of taskwarrior-web, which I never completed. Maybe they ll be useful in and of themselves, and maybe not. In any case, they are maintained by pkg-ruby-extras-maintainers, but I m the sole developer in Uploaders and should be removed: Fixed in git.
   • ruby-blockenspiel
   • ruby-parseconfig
   • ruby-rack-flash3
   • ruby-simple-navigation
   • ruby-sinatra-simple-navigation
   • ruby-term-ansicolor
   • ruby-versionomy
7. Debian Live stuff: I am listed in Uploaders for live-manual (fixed in git) and debian-installer-launcher (fixed in git) and need to be removed.
8. O: eeepc-acpi-scripts. The defunct Debian EeePC project has just this one package. Recently, the mailing list was asked about its status, and it was recently NMU d. To my knowledge, nobody from the original team remains to take care of it, so it needs a new maintainer. I should be removed from Uploaders, and since the Debian Eee PC Team no longer exists, it should be removed as maintainer. It is effectively orphaned unless someone speaks up.

There are also some Alioth projects / lists that are defunct that I ll need to talk to the Alioth admins about cleaning up in the coming days. One of these is <debian-eeepc-devel@lists.alioth.debian.org> and since it is still listed as the maintainer of eeepc-acpi-scripts, that needs to be sorted out before the list can be closed. Thanks again, and see you around!

Stay in touch For those of you who would like to stay in touch, here are some ways to do that:

• Follow my blog: http://syn.theti.ca
  If you already do that, great! If not, welcome to my blog! For the past couple of years you may have noticed a decrease in technical content and increase in local trails and conservation oriented posts. You can expect more of the latter.
• Say hi to me on irc: SynrG (also SynrGy) on irc.oftc.net (irc.debian.org) or irc.freenode.net.
  I still intend to hang out and offer support when I can, just no longer as a developer. Channel #debian-offtopic on either network is a good place to catch up with me socially.
• Follow me on Facebook: https://www.facebook.com/SynrG
  For better or worse, a lot of the trails and conservation folks hang out here, and many of you in the Debian community are already my Facebook friends.
• Look for my Bluff Trail posts on their site: https://wrweo.ca
  Providing tech support to this organization is where much of my time and energy is going these days. I post here once in a while, but do most of my work behind the scenes as a volunteer and, newly this year, as a board member.

AppRecommender is a package recommender system for Debian. This project is also one of the Debian projects that is being worked on by some Google Summer of Code students. As one of these students, I will now present what my Google Summer of Code project is and what I have achieved so far.

Hello, my name is Lucas Moura and this post will present AppRecommender. This project is a package recommender system for Debian systems. The intent of this application is to look for packages that users have already installed in their system and recommend new useful packages based on them. This approach is similar as the one seen on Netflix or Amazon, where the movies or goods that a user has already seen determine other items that will be recommended.

PocketCHIP is the pocket sized Linux terminal I always used to want. Which is to say, it runs (nearly) stock Debian, X, etc, it has a physical keyboard, and the hardware and software is (nearly) non-proprietary and very hackable. Best of all, it's fun and it encourages playful learning. It's also clunky and flawed and constructed out of cheap components. This keeps it from being something I'd actually carry around in my pocket and use regularly. The smart thing they've done though is embrace these limitations, targeting it at the hobbiest, and not trying to compete with smart phones. The PocketCHIP is its own little device in its own little niche. Unless you're into hardware hacking and want to hook wires up to the GPIO pins, the best hardware feature is the complete keyboard, with even Escape and Control and arrow keys. You can ssh around and run vi on it, run your favorite REPL (I use ghci) to do quick programming, etc. The keyboard is small and a little strange, but you get used to it quickly; your QWERTY muscle memory is transferrable to it. I had fun installing nethack on it and handing it to my sister who had never played nethack before, to watch her learn to play. The screen resolution is 480x272, which is pretty tiny. And, it's a cheap resistive touchscreen, with a bezil around it. This makes it very hard to use scroll bars and icons near the edge of the screen. The customized interface that ships with it avoids these problems, and so I've been using that for now. When I have time, I plan to put a fullscreen window manager on it, and write a pdmenu menu configuration for it, so everything can be driven using the keyboard. I also have not installed Debian from scratch on it yet. This would be tricky because it uses a somewhat patched kernel (to support the display and wifi). The shipped distribution is sadly not entirely free software. There are some nonfree drivers and firmwares. And, they included a non-free gaming environment on it (a very nice one for part of the audience, that allows editing the games, but non-free nevertheless). They did do a good job of packaging up all the custom software they include on it, although they don't seem to have published source packages for everything. (They might be infringing my GPL copyright of flash-kernel by distributing a modified version without source. I say "might" because flash-kernel is a pile of shell scripts, so you could probably extract the (probably trivial) modifications. Still.. Also, they seem to have patched network-manager in some way and I wasn't able to find the corresponding source.) The battery life is around 5 hours. Unfortunately the "sleep" mode only turns off the backlight and maybe wifi, and leaves the rest of the system running. This and the slightly awkward form factor too big to really comfortably fit in a pocket limit the use of PocketCHIP quite a bit. Perhaps the sleeping will get sorted out, and perhaps I'll delete the GPIO breakout board from the top of mine to make it more pocket sized.

About a year ago, I bought a Projector after I finally admitted that I could actually use a TV in my apartment. I settled on buying a ViewSonic PJD5132. It was a really great value, and has been nothing short of a delight to own. I was always a bit curious about the DB9 connector on the back of the unit, so I dug into the user manual, and found some hex code strings in there. So, last year, between my last gig at the Sunlight Foundtion and USDS, I spent some time wandering around the US, hitting up DebConf, and exploring Washington DC. Between trips, I set out to figure out exactly what was going on with my Projector, and see if I could make it do anything fun. So, I started off with basics, and tried to work out how these command codes were structured. I had a few working codes, but to write clean code, I'd be better off understanding why the codes looked like they do. Let's look at the "Power On" code. 0x06 0x14 0x00 0x04 0x00 0x34 0x11 0x00 0x00 0x5D Some were 10 bytes, other were 11, and most started with similar looking things. The first byte was usually a 0x06 or 0x07, followed by two bytes 0x14 0x00, and either a 0x04 or 0x05. Since the first few bytes were similarly structured, I assumed the first octet (either 0x06 or 0x07) was actually a length, since the first 4 octets seemed always present. So, my best guess is that we have a Length byte at index 0, followed by two bytes for the Protocol, a flag for if you're Reading or Writing (best guess on that one), and opaque data following that. Sometimes it's a const of sorts, and sometimes an octet (either little or big endian, confusingly). Right. OK. So, let's get to work. In the spirit of code is data, data is code, I hacked up some of the projector codes into a s-expression we can use later. The structure of this is boring, but it'll let us both store the command code to issue, as well as define the handler to read the data back. As well as defining some of the const responses that come back from the Projector itself. These are pretty boring, but it's helpful to put a name to the int that falls out. After defining a few simple functions to write the byte arrays to the serial port as well as reading and understanding responses from the projector, I could start elaborating on some higher order functions that can talk projector. So the first thing I wrote was to make a function that converts the command entry into a native Hy function. Fun. Fun! Now, we can invoke it to create a Hy & Python importable API wrapper in a few lines! Cool. So, now we can import things like power-on from *commands* which takes a single argument (serial) for the serial port, and it'll send a command, and return the response. The best part about all this is you only have to define the data once in a list, and the rest comes for free. Finally, I do want to be able to turn my projector on and off over the network so I went ahead and make a Flask "API" on top of this. First, let's define a macro to define Flask routes: Now, we can define how we want our API to look, so let's define the power route, which will expand out into the Flask route code above. And now, let's play with it! Or, the volume! Check out the full source over at github.com/paultag/PJD5132!

This doesn t appear to cover the other kind of comment-moderation problem: that where overmoderation and attachment to poster identity leads to an environment of stifling conventionalism. Photography communities in particular (e.g. flickr, instagram, 500px) are vulnerable to turning into circlejerks where no-one is willing to say what they mean for fear of appearing the negative nancy (no pun intended) and where high post-count contributors poorly-supported opinions become elevated above said views merits. In such communities the typical discussion is at the level of tepid platitude: good exposure! , nice depth of field! , or cool HDR! . On the other end of the scale there s the imageboard style of community where anonymity is the norm, feedback is uncompromisingly harsh, and uselessly opaque criticism appears such on its face; unsuited to the overly sensitive but hideously valuable to the advancing novice. Ordinary web forums, with tools oriented towards a punitive he said the n-word! delete his account and everything he s posted! persona non grata, in damnatio memoriae! school of moderation, strongly tend to the former.

I bought a new laptop E200HA, because my previous was a MacBook and It broke after a fall into the ground. I let it boot first in Win10 to check if everything was OK and because I could not found the way to enter in the UEFI/BIOS. It is F2 and is edge triggered. It boots fast into Win10, but I got the feeling of being a little slow. No worries because I it bought for running Debian and because of the autonomy of the battery, 14hours playing music according to Asus. A little research if the new laptop could run Linux almost return no hits, but one very valuable link on how to setup the Wifi. So I got the feeling that I needed a Debian stretch CD for installation. So I download the first installation DVD from here. Run a trial of the DVD image using kvm

kvm -m 2047 -cdrom debian-stretch-DI-alpha7-amd64-DVD-1.iso

Found that the installer DVD now have the functionality of Live CD. This will be useful. Copy the image to a USB stick using dd command. I turned on the E200HA, entered into the UEFI/BIOS by pressing and releasing the F2 key. Turned off the secure boot and select USB storage for boot. The E200HA happily boot the Linux and I select the rescue mode. Using another USB stick of 32GB that was formatted in xfs, because of the lower slack for storing the inodes than ext3/4. In this USB stick I put a raw image of the internal storage of the E200HA, preserving this way the Win10. Another reboot, this time for installation of Debian stretch. It detected the lack of firmware files, for the WiFi adaptor. This link come very handy. The instructions are for an older Linux kernel. So I recommend doing something similar to the following commands:

git clone https://github.com/ajaybhatia/Qualcomm-Atheros-QCA9377-Wifi-Linux
cd Qualcomm-Atheros-QCA9377-Wifi-Linux/firmware-only
tar cvf QCA9377.tar QCA9377

Copy the tar file to a a second USB stick and connect it to the other USB port. This tar is not the files the Debian installer are expecting, so you need to change to the second console "Alt-F2", press enter to activate a shell, and do the following commands:

cd /lib/firmware
mkdir ath10k
mount /dev/sdb1 /mnt
cd ath10k
tar xf /mnt/QCA9377.tar

Return to the first console "Alt-F1" and continue with the installation. The list of missing firmware files is reduced and the WiFi can work. I had problems with the WiFI, but was because a neighbor router was on the same channel, since I changed the channel of my router the WiFi is working as a charm. The following links maybe useful in the future or as a reference: kvalo/ath10k-firmware kernel/git/firmware/linux-firmware.git

This release adds a new, experimental server implementation: remctl-shell. As its name implies, this is designed to be run as a shell of a dedicated user rather than as a server. It does not use the remctl protocol, instead relying on ssh to pass in the command and user information (via special authorized_keys configuration). But it supports the same configuration as the normal remctl server. It can be useful for allowing remctl-style simple RPC in environments that only use ssh public key authentication. Also in this release is a new configuration option, sudo, which is like the existing user option to run a command as another user but uses sudo instead of calling setuid() directly. This allows the server to switch users when running as a non-root user, which will be the normal case for remctl-shell. The remctl-shell implementation in this release should be considered a first draft and is likely to improve in the future. (I already have a list of things that probably should be improved.) You can get the latest release from the remctl distribution page.

Each release of Debian has a shiny new theme, which is visible on the boot screen, the login screen and, most prominently, on the desktop wallpaper. Debian plans to release Stretch next year. As ever, we need your help in creating its theme! You have the opportunity to design a theme that will inspire thousands of people while working in their Debian systems. They might be people working in exciting NASA missions: Or DYI users who decided to make a matching keyboard: If you're interested, please take a look at https://wiki.debian.org/DebianDesktop/Artwork/Stretch

Talks have been finished, and as a special present to the participants, Pavneet has organized an excursion that probably was one of the best I ever had. First we visited the Toronto Reference Library where we were treated to a delicious collection of rare books (not to mention all the other books and architecture), and then a trip through the Ismaili Centre Toronto and the Aga Khan Museum.
(Kelmscott press edition from 1892 of William Morris A Dream of John Ball.) All these places were great pieces of architecture with excellent samples of the writing and printing art. And after all that and not to be mentioned, the conference dinner evening cruise! Our first stop was the Toronto Reference Library. Designed by Raymond Moriyama, it features a large open atrium with skylights, and it gives the library an open and welcoming feeling. We were told that it resembles a tea cup that needs to be filled with knowledge.
The library also features running water at several places the architect had the idea that natural ambient noise is more natural for a library than the eclectic silence that anyway never happens. Originally there were lots of greens hanging down into the Atrium, resembling the Hanging Gardens, but they have been scrapped due to financial reasons. But there are still green oasis like this beautiful green wall in a corner of the library.
We were guided first to the fifth floor where the special collection is housed. And what a special collection. The librarian in charge has laid out about 20 exquisite books starting from early illuminated manuscripts over incunabula to high pieces of printing art from the 18th and 19th century. Here we have a illuminated script in Carolingian minuscule.
What was really surprising for all of us in this special collection that all these books were simply laid out in front of us, that the librarian touched and used it without gloves, and above all, that he told us that if one wants it is common practice to check out these books for study sessions and enjoy them on the spot in the reading room. I don t know any other library that allows you to actually handle these rare and beauty specimens! The library not only featured lots of great books, it also had some art installation like these light rods.
In one of the books I found by chance a map of my hometown of Vienna. Looking at this map from very old times, the place where I grew up is still uninhabited somewhere in the far upper right corner of the map. Times have changed.
After we left this open and welcoming treasure house of beautiful books, we moved to the Aga Khan Museum and Ismaili Centre Toronto, which are standing face-to-face separated by some water ponds in the Aga Khan park a bit outside of central Toronto. Here we see the Ismaili Centre from the Aga Khan Museum entrance. The big glass dome is the central prayer room, and is illuminated at night. Just one detail one can see in the outer wall one part that looks like glass, too. This is the prayer alcove in the back of the prayer hall, and is made from huge slabs of Onyx that are also lit up in the night.
The Ismaili Centre, designed by Charles Correa combines modern functional and simple style with the wonderful ornamental art of the Islam heritage. The inside of the Ismaili Centre features many pieces of exquisite art calligraphy, murals, stone work, etc here is a medallion made from precious stone and set onto a hand-carved wall.
A calligraphy on the wall in the Ismaili Centre
Following the Ismaili Centre we turned to the Aga Khan museum which documents Islamic art, science, and history with an extensive collection. We didn t have much time, and in addition I had to do some fire-fighting over the phone, but the short trip through the permanent collection with samples of excellent calligraphy was amazing.
After returning from this lovely excursion and a short break, we set off for the last stop for tonight, the dinner cruise. After a short bus ride we could board our ship and off we go. Although the beer selection was not on par with what we are used from carft breweries, the perfectly sized boat with two decks and lots of places to hang around invited us to many discussions and chitchats. And finally I could enjoy also the skyline of Toronto.
After the dinner we had some sweets, one of which was a specially made cake with the TUG 2016 logo on it. I have to say, it was not only this cake but the whole excellent and overboarding food we had during all these days, that will make me go on diet when I am back in Japan. Pavneet organized for the lunch breaks three different style of kitchens (Thai, Indian, Italian), then the excursions to local brewers and and and If it wouldn t be for TeX, I would call it a Mastkur .
During the cruise we also had a little ceremony thanking Jim for his work as president of the TUG, but above all Pavneet for this incredible well organized conference. I think everyone agreed that this was the best TUG conference since long.
During the ceremony, Pavneet also announced the winners of the TUG 2016 fountain pen auction. These pens have a long history/travel behind them, see details on the linked page, and were presented to the special guests of the conference. Two remaining pens were auctioned with funds going to the TUG. The first one was handed over to Steve Grathwohl, and to my utter surprise the second one to myself. So now I am a happy owner of a TUG 2016 fountain pen. What a special feature! Just one more detail about these pens: They are traditional style, so without ink capsules, but one needs to insert the ink with a syringe. I guess I need to stack up a bit at home, and more importantly, train my really ugly hand-writing, otherwise it would be a shame to use this exquisite tool. We returned to the harbor around 10pm, and back to the hotel, where there was much greeting and thanking, as many people will return the following day.
I will also leave on Friday morning to meet with friends, thus I will not be participating in (and not reporting on) the last excursion of the TUG 2016. I will leave Toronto and the TUG 2016 with (nearly) exclusively good memories of excellent talks, great presentations, wonderful excursions, and lots of things I have learned. I hope to see all of the participants on next year s TUG meeting and I hope I will be able to attend it. Thanks a lot to Pavneet, you have done an incredible job. And last but not least, thanks to your lovely wife for letting you do all this, I know how much time we did steal from her. A few more photos can be found at the album Day 4 Books, ooh books.

As I have said here a couple of times already, I am teaching a diploma course on embedded Linux at UNAM, and one of the modules I'm teaching (with Sandino Araico) is the boot process. We focus on ARM for obvious reasons, and while I have done my reading on the topic, I am very far from considering myself an expert. So, after attending Martin Michlmayr's Debian on ARM devices talk, I decided to do its subtitles as part of my teaching job. This talk gives a great panorama on what actually has to happen in order to get an ARM machine to boot, and how support for new ARM devices comes around to Linux in general and to Debian in particular Perfect for our topic! But my students are not always very fluent in English, so giving a hand is always most welcome. In case any of you dear readers didn't know, we have a DebConf subtitling team. Yes, our work takes much longer to reach the public, and we have no hopes whatsoever in getting it completed, but every person lending a hand and subtitling a talk that they thought was interesting helps a lot to improve our talks' usability. Even if you don't have enough time to do the whole talk (we are talking about some 6hr per 45 minute session), adding a bit of work is very very very welcome. So...

• Do you want to follow Martin's talk with subtitles?
  • Get the video file
  • Get the subtitles
  • Use your favorite program In my case:
    $ vlc Debian_on_ARM_devices_2.webm --sub-file Debian_on_ARM_devices.srt
  • [update] Or watch online at Amara!
• Do you want to help the subtitling effort?
  • Read the Wiki page on the Subtitling team work (feel free to fill in bits of missing information you will surely find!)
  • Choose a video from the list to work on
  • You can either work online on the DebConf team of the Amara webapp or join the Alioth team and contribute directly to the Git tree

Enjoy And thanks in advance for your work!

On week 8, I have finished to creating my API On the libring client. I coded my client in two different parts The right click menu where I launch my tools. To do that I need to: -call my API who speaks with the daemon
-send a signal connect with my second part, the goal is to display or not smartInfo (not implement yet)
-The call view part where I display all my information. I passed a lot of time trying to understand some part of the code and the link between my .ui and .cpp file. I had other issues with the clutter. Now everything is display like I want, but I have some little bug in some particular case. On week 10, I will work on the link between my two part on the client and debugging some stuff but I won t tell you everything Keep in touch! See you next week! :)

kvm virtualization on a liberated X200, part 1

As the libreboot website warns https://libreboot.org/docs/hcl/x200.html: there are issues with virtualization on x200 without microcode updated.

Virtualization is something that I use, and I have a number of VMs on that laptop, managed with libvirt; since it has microcode version 1067a, I decided to try and see if I was being lucky and virtualization was working anyway.

The result is that the machines no longer start: the kernel loads, and then it crashes and reboots. I don't remember why, however, I tried to start a debian installer CD (iso) I had around, and that one worked.

So, I decided to investigate a bit more: apparently a new installation done from that iso (debian-8.3.0-amd64-i386-netinst.iso) boots and works with no problem, while my (older, I suspect) installations don't. I tried to boot one of the older VMs with that image in recovery mode, tried to chroot in the original root and got failed to run command '/bin/bash': Exec format error.

Since that shell was lacking even the file command, I tried then to start a live image, and choose the lightweight debian-live-8.0.0-amd64-standard.iso: that one didn't start in the same way as the existing images.

Another try with debian-live-8.5.0-i386-lxde-desktop.iso confirmed that apparently Debian > 8.3 works, Debian 8.0 doesn't (I don't have ISOs for versions 8.1 and 8.2 to bisect properly the issue).

I've skimmed the release notes for 8.3 https://www.debian.org/News/2016/20160123 and noticed that there was an update in the intel-microcodehttps://packages.debian.org/jessie/intel-microcode package, but AFAIK the installer doesn't have anything from non-free, and I'm sure that non-free wasn't enabled on the VMs.

My next attempt (thanks tosky on #debian-it for suggesting this obvious solution that I was missing :) ) was to run one of the VMs with plain qemu instead of kvm and bring it up-to-date: the upgrade was successful and included the packages in this screenshot, but on reboot it's still not working as before.

http://social.gl-como.it/photos/valhalla/image/ecb0e193b16fbd507d0148636177961b

Right now, I think I will just recreate from scratch the images I need, but when I'll have time I'd like to investigate the issue a bit more, so hopefully there will be a part 2 to this article.

The last day of TUG 2016, or at least the last day of talks, brought four one-hour talks from special guests, and several others, where many talks told us personal stories and various histories.
A great finish of a great conference. Jennifer Claudio The case for justified text Due to a strange timezone bug in my calendar program, I completely overslept a morning meeting and breakfast, as well as the first talk, so unfortunately I don t have anything to report about this surely intersting talk comparing justification in various word processors and TeX. Leyla Akhmadeeva, Rinat Gizatullin, Boris Veytsman Are justification and hyphenation good or bad for the reader? Still half dizzy and without coffee, I couldn t really follow this talk, and only woke up till the end when there was a lot of interesting discussion about speed reading and its non-existence (because it is simply skimming over text), and improvements on reading comprehension. Charles Bigelow Looking for legibility Another special guest, Charles Bigelow, presented a huge pool of research and work into readability, and how attitude and usage of fonts change over time. A very involving and well laid out talk, full of interesting background images and personal opinions and thoughts. Charles also touched onto topics of readability on modern devices like e-readers and mobiles. He compared the recent developments in font design for mobile devices with their work on Lucida 20+ years ago, and concluded that both arrived at the same solutions. A very educating and amusing talk packed full with information on readability. I surely will revisit the recording in a study session. David Walden Some notes on the history of digital typography David touches on many topics of the history of digital typography which he has experienced himself over the years: First the development of newspaper production and printing, then the evolvement of editors from simple text editors over word processors to full-fledged DTP programs. Finally he touches on various algorithmic problems that appear in the publishing business. Tim Inkster The beginning of my career Tim, our fanatastic guide through his print shop the Procupine s Quill on the second excursion day, talked about his private ups and downs in the printing business, all filled with an infinite flow of funny stories and surprising anecdotes. Without slides and anything but his voice and his stories, he kept us hanging on his lips without a break. I recommend watching the recording of his talk because one cannot convey the funny comments and great stories he shared with us in this simple blog. Joe Clark Type and tiles on the TTC Joe unveils the history of rise and fall of the underground types and
tiles in Toronto. It is surprising to me that a small metro network as in Toronto can have such a long history of changes of design, layout, presentation. Some of the photos completely stymed me how can anyone put up signs like that? I was thinking. To quote Joe (hopefully I remember correctly):

You see what happens without adult supervision.

Abdelouahad Bayar Towards an operational (La)TeX package supporting optical scaling of dynamic mathematical symbols A technical talk about a trial in providing optical scaling of mathematical symbols. As far as I understand it tries to improve on the TeX way of doing extensible math symbols by glueing things together. It seems to be highly involved and technically interesting project, but I couldn t completely grasp the aim of it. Michael Cohen, Blanca Mancilla, John Plaice Zebrackets: A score of years and delimiters John introduced us to Zebrackets, stripped parentheses and brackets, to help us keep track of pairing of those beasts. But as we know, Zebras are very elusive animals, and so we saw lots of stripped brackets around. The idea of better markup of matching parentheses is definitely worth developing. Charles Bigelow Probably approximately not quite correct: Revise, repeat The second talk of Charles, this time on the history of the Lucida fonts, from the early beginnings drawn on graph paper to recent developments using FontLab producing OpenType fonts. A truly unique crash course through the development of one of the very big families of fonts, and one of the first outside Computer Modern that had also support for proper math typesetting in TeX.

Aggressively legible!

One of the key phrases that popped up again and again was aggressively legible, mostly in negative connotations as far to fat symbols or far to big Arabic letters. But for me this font family is still close to my heart. I purchased it back than from Y&Y for my PhD thesis, and since then have upgraded to the TUG version including the OpenType fonts, and I use them for most of my presentation. Maybe I like the aggressive legibility! Chuck slided in lots of nice comments about Kris Holmes, the development practice in their cooperation, stories of business contacts, and many more, making this talk a very lively and amusing, and at the same time very educating talk.

---

This concluded the TUG conference talks, and we thanked Pavneet for his excellent organization. But since we still have up to two days of excursions, many people dispersed quickly, just to meet again for a optional Type and Tile Tour 3-5 subway stops with discussion of typesetting This guided tour through the underground of Toronto, guided by Joe Clark who spoke in the morning about this topic, was attended by far too many participants. I think there were around 25 when we left. I thought that this will not work out properly, and so decided to leave the group and wander around alone. The last program point for today was dinner with a blues music concert in the near by Jazz Bistro:
Excellent life music in a bit schick/sophisticated atmosphere was a good finish for this excellent day. With Herb from MacTeX and his wife we killed two bottles of red wine, before slowly tingling back to the hotel. A great finishing day of talks.

By popular request... If you go to the Debian video archive, you will notice the appearance of an "lq" directory in the debconf16 subdirectory of the archive. This directory contains low-resolution re-encodings of the same videos that are available in the toplevel. The quality of these videos is obviously lower than the ones that have been made available during debconf, but their file sizes should be up to about 1/4th of the file sizes of the full-quality versions. This may make them more attractive as a quick download, as a version for a small screen, as a download over a mobile network, or something of the sorts. Note that the audio quality has not been reduced. If you're only interested in the audio of the talks, these files may be a better option.

The second day of TUG 2016 was again full of interesting talks spanning from user experiences to highly technical details about astrological chart drawing, and graphical user interfaces to TikZ to the invited talk by Robert Bringhurst on the Palatino family of fonts. With all these interesting things there is only one thing to compain I cannot get out of the dark basement and enjoy the city After a evening full of sake and a good night s sleep we were ready to dive into the second day of TUG. Kaveh Bazargan A graphical user interface for TikZ The opening speaker of Day 2 was Kaveh. He first gave us a quick run-down on what he is doing for business and what challenges publishers are facing in these times. After that he introduced us to his new development of a command line graphical user interface for TikZ. I wrote command line on purpose, because the editing operations are short commands issued on a kind of command line, which will give an immediate graphical feedback. Basic of the technique is a simplified TikZ-like meta language that is not only easy to write, but also easy to parse. While the amount of supported commands and features of TikZ is still quite small, I think the basic idea is a good one, and there is a good potential in it. Matthew Skala Astrological charts with horoscop and starfont Next up was Matthew who introduced us to the involved task of typesetting astrological charts. He included comparisons with various commercial and open source solutions, where Matthew of course, but me too, felt that his charts came of quite well! As an extra bonus we got some charts of famous singers, as well as the TUG 2016 horoscope. David Tulett Development of an e-textbook using LaTeX and PStricks David reported on his project to develop an e-textbook on decision modeling (lots of math!) using LaTeX and PStricks. His e-book is of course a PDF. There were a lot of very welcoming feedback free (CC-BY-NC-ND) textbooks for sciences are rare and we need more of them. Christian Gagn An Emacs-based writing workflow inspired by TeX and WEB, targeting the Web Christian s talk turned around editing and publishing using org-mode of Emacs and the various levels of macros one can use in this setup. He finished with a largely incomprehensible vision of a future equational logic based notation mode. I have used equational logic in my day-in-day-out job, and I am not completely convinced that this is a good approach for typesetting and publishing but who knows, I am looking forward to a more logic-based approach! Barbara Beeton, Frank Mittelbach In memoriam: Sebastian Rahtz (1955-2016) Frank recalled Sebastian s many contribution to a huge variety of fields, and recalled our much missed colleague with many photos and anecdotes. Jim Hefferon A LaTeX reference manual Jim reported about the current state of a LaTeX reference manual, which tries to provide a documentation orthogonally to the many introduction and user guides available, by providing a straight down-to-earth reference manual with all the technical bells and whistles necessary. As I had to write myself a reference manual for a computer language, it was very interested to see how they dealt with many of the same problems I am facing. Arthur Reutenauer, Mojca Miklavec Hyphenation past and future: hyph-utf8 and patgen Arthur reports about the current statue of the hyphenation pattern project, and in particular the license and usage hell they recently came into with large cooperations simply grabbing the patterns without proper attribution. In a second part he gave a rough sketch of his shot at a reimplementation of patgen. Unfortunately he wrote in rather unreadable hand-writing on a flip-chart, which made only the first line audience to actually see what he was writing. Federico Garcia-De Castro TeXcel? As an artist organizing large festivals Federico has to fight with financial planning and reports. He seemed not content with the abilities of the usual suspects, so he developed a way to do Excel like book-keeping in TeX. Nice idea, I hope I can use that system for the next conference I have to organize! Jennifer Claudio A brief reflection on TeX and end-user needs Last speaker in the morning session was Jennifer who gave us a new and end-user s view onto the TeX environment, and the respective needs. These kind of talks are a very much welcomed contrast to technical talks and hopefully all of us developers take home some of her suggestions. Sungmin Kim, Jaeyoung Choi, Geunho Jeong MFCONFIG: Metafont plug-in module for the Freetype rasterizer Jaeyoung reported about an impressive project to make Metafont fonts available to fontconfig and thus windowing systems. He also explained their development of a new font format Stemfont, which is a Metafont-like system that can work also for CJK fonts, and which they envisage to be built into all kind of mobile devices. Michael Sharpe New font offerings Cochineal, Nimbus15 and LibertinusT1Math Michael reports about his last font projects. The first two being extensions of the half-made half-butchered rereleased URW fonts, as well as his first (?) math font project. I talked to him over lunch one day, and asked him how many man-days he need for these fonts, and his answer was speaking a lot: For the really messed up new URW fonts, like Cochineal, he guessed about 5 man-months of work, while other fonts only needed a few days. I think we all can be deeply thankful to all the work he is investing into all these font projects. Robert Bringhurst The evolution of the Palatino tribe The second invited talk was Robert Bringhurst, famous for his wide contributions to typpography, book culture in general, as well as poetry. He gave a quick historic overview on the development of the Palatino tribe of fonts, with lots of beautiful photos. I was really looking forward to Robert s talk, and my expectations were extremely high. And unfortunately I must say I was quite disappointed. Maybe it is his style of presentation, but the feeling he transfered to me (the audience?) was that he was going through a necessary medical check, not much enjoying the presentation. Also, the content itself was not really full of his own ideas or thoughts, but a rather superficial listing of historical facts. Of course, a person like Robert Bringhurst is so full of anecdotes and background knowledge still was a great pleasure to listen and lots of things to learn, I only hoped for a bit more enthusiasm. TUG Annual General Meeting The afternoon session finished with the TUG Annual General Meeting, reports will be sent out soon to all TUG members. Herbert Schulz Optional workshop: TeXShop tips & tricks After the AGM, Herbert from MacTeX and TeXShop gave an on-the-spot workshop on TeXShop. Since I am not a Mac user, I skipped on that.

---

Another late afternoon program consisted of an excursion to Eliot s bookshop, where many of us stacked up on great books. This time again I skipped and took a nap. In the evening we had a rather interesting informal dinner in the food court of some building, where only two shops were open and all of us lined up in front of the Japanese Curry shop, and then gulped down from plastic boxes. Hmm, not my style I have to say, not even for informal dinner. But at least I could meet up with a colleague from Debian and get some gpg key signing done. And of course, talking to all kind of people around. The last step for me was in the pub opposite the hotel, with beer and whiskey/scotch selected by specialists in the field.

I have a long overdue blog entry about what happened in recent times. People that follow my tweets did catch some things. Most noteworthy there was the Trans*Inter*Congress in Munich at the start of May. It was an absolute blast. I met so many nice and great people, talked and experienced so many great things there that I'm still having a great motivational push from it every time I think back. It was also the time when I realized that I in fact do have body dysphoria even though I thought I'm fine with my body in general: Being tall is a huge issue for me. Realizing that I have a huge issue (yes, pun intended) with my length was quite relieving, even though it doesn't make it go away. It's something that makes passing and transitioning for me harder. I'm well aware that there are tall women, and that there are dedicated shops for lengthy women, but that's not the only thing that I have trouble with. What bothers me most is what people read into tall people: that they are always someone they can lean on for comfort, that tall people are always considered to be self confident and standing up for themselves (another pun, I know ... my bad). And while I'm fine with people coming to me for leaning on to, I rarely get the chance to do so myself. And people don't even consider it. When I was there in Munich, talking with another great (... pun?) trans woman who was as tall as me I finally had the possibility to just rest my head on her shoulder and finally feel the comfort I need just as much as everyone else out there, too. Probably that's also the reason why I'm so touchy and do go Free Hugging as often as possible. But being tall also means that you are usually only the big spoon when cuddling up. Having a small mental breakdown because of realizing that didn't change the feeling directly but definitely helped with looking for what I could change to fix that for myself. Then, at the end of may, the movie FtWTF - female to what the fuck came to cinema. It's a documentary about six people who got assigned female at birth. And it's absolutely charming, and has great food for thoughts in it. If you ever get the chance to watch it you definitely should. And then came debconf16 in Capetown. The flight to there was canceled and we had to get rebooked. The first offer was to go through Dubai, and gladly a colleague did point out to the person behind the desk that that wouldn't be safe for myself and thus out of scope. In the end we managed to get to Capetown quite nice, and even though it was winter when the sun was shining it was quite nice. Besides the cold nights that is. Or being stuck on the way up to table mountain because a colleague had cramps in his lags and we had to call mountain rescue. Gladly the night was clear, and when the mountain rescue finally got us to top and it was night already we had one of the nicest views from up there most people probably never will experience. And then ... I got invited to a trans meetup in Capetown. I was both excited and nervous about it, what to expect there. But it was simply great. The group there was simply outstandingly great. The host gave update information on progress on clinical support within south Africa, from what I took with me is that there is only one clinic there for SRS which manages only two people a year which is simply ... yuck. Guess you can guess how many years (yes, decades) the waiting line is ... I was blown away though by the diversity of the group, on so many levels, most notably on the age spectrum. It was a charm to meet you all there! If you ever stop by in Capetown and you are part of the LGBTIQ community, make sure you get in contact with the Triangle Project. But, about the real reason to write this entry: I was approached at Debconf by at least two people who asked me what I thought about creating an LGBTIQA+ group within Debian, and if I'd like to push for that. Actually I think it would be a good idea to have some sort of exchange between people on the queer spectrum (and I hope I don't offend anyone with just saying queer for LGBTIQA+ people). Given that I'm quite outspoken people approach me every now and then so I'm aware that there is a fair amount of people that would fall into that category. On the other hand some of them wouldn't want to have it publicly known because it shouldn't matter and isn't really the business of others. So I'm uncertain. If we follow that path I guess something that is closed or at least offers the possibility to have a closed communication would be needed to not out someone by just joining in the discussion. It's was easier with Debian Women where it was (somewhat) clear that male participants are allies supporting the cause and not considered being women themselves, but often enough (mostly cis hetero male) people are afraid to join a dedicated LGBTIQA+ group because they have the fear of having their identity judged. These things should be considered before creating such a place so that people can feel comfortable when joining and know what to expect beforehand. For the time being I created #debian-diversity on irc.debian.org to discuss how to move forward. Please bear in mind that even the channel name is up for discussion. Acronyms might not be the way to go in my opinion, just read back up the discussion that lead to the Diversity Statement of Debian where the original approach was to start listing groups for inclusiveness but it was quickly clear that it can get outdated too easily. I am willing to be part of that effort, but right now I have some personal things to deal which eat up a fair amount of my time. My kid starts school in September (yes, it's that long already, time flies ...). And it looks like I'll have to move a second time in the near future: I'll have to leave my current flat by the end of the year and the Que[e]rbau I'm moving into won't be ready by that time to host me yet ... F*ck. :(

The first day of the real conference started with an excellent overview of what one can do with TeX, spanning from traditional scientific journal styles to generating router configuration for cruising ships.
All this was crowned with an invited talk my Kevin Larson from Microsoft s typography department on how to support reading comprehension. Pavneet Aurora Opening: Passport to the TeX canvas Pavneet, our never-sleeping host and master of organization, opened the conference with a very philosophical introduction, touching upon a wide range of topics ranging from Microsoft, Twitter to the beauty of books, pages, and type. I think at some point he even mentioned TeX, but I can t remember for sure. His words put up a very nice and all-inclusive stage, a community that is open to all kind of influences with any disregard or prejudice. Let us hope that is reflects reality. Thanks Pavneet. Geoffrey Poore Advances in PythonTeX Our first regular talk was by Geoffrey reporting on recent advances in PythonTeX, a package that allows including python code in your TeX document. Starting with an introduction to PythonTeX, Geoggrey reports about an improved verbatim environment, fvextra, which patches fancyvrb, and improved interaction between tikz and PythonTeX. As I am a heavy user of listings for my teaching on algebraic specification languages, I will surely take a look at this package and see how it compares to listings. Stefan Kottwitz TeX in industry I: Programming Cisco network switches using TeX Next was Stefan from Lufthansa Industry Solutions, who reported first about his working environment, Cruise Ships with a very demanding IT infrastructure he has to design and implement. Then he introduced us to his way of generating IP configurations for all the devices using TeX. The reason he chose this method is that it allows him to generate at the same time proper documentation. It was surprising for me to hear that by using TeX he could far more efficiently and quicker produce well designed and easily accessible documentation, which helped both the company as well as made the clients happy! Stefan Kottwitz TeX in industry II: Designing converged network solutions After a coffee break, Stefan continued his exploration into industrial usage of TeX, this time about using tikz to generate graphics representing the network topology on the ships. Boris Veytsman Making ACM LaTeX styles Next up was Boris which brought us back to traditional realms of TeX when he guided us into the abyss of ACM LaTeX styles he tried to maintain for some time, until he plunged into a complete rewrite of the styles. Frank Mittelbach Alice goes floating global optimized pagination including picture placements The last talk before lunch (probably a strategic placement, otherwise Frank would continue for hours and hours) was Frank on global optimization of page breaks. Frank showed us what can and can not be done with current LaTeX, and how to play around with global optimization of pagination, using Alice in Wonderland as running example. We can only hope that his package is soon available in an easily consumable version to play around. Thai lunch Pavneet has organized three different lunch-styles for the three days of the conference, today s was Thai with spring rools, fried noodles, one kind of very interesting orange noodles, and chicken something. Michael Doob baseball rules summary After lunch Michael gave us an accessible explanation of the most arcane rules a game can have the baseball rules by using pseudo code. I think the total number of loc needed to explain the overall rules would fill more pages than the New York phonebook, so I am deeply impressed by all those who can understand these rules. Some of us even wandered off in the late afternoon to see a match with life explanations of Michael. Amartyo Banerjee, S.K. Venkatesan A Telegram bot for printing LaTeX files Next up was Amartyo who showed a Telegram (as in messenger application) bot running on a Raspberry Pi, that receives (La)TeX files and sends back compiled PDF files. While it is not ready for consumption (If you sneeze the bot will crash!), it looks like a promising application. Furthermore, it is nice to see how open APIs (like Telegram) can spur development of useful tools, while closed APIs (including threatening users, like WhatApp) hinders it. Norbert Preining Security improvements in the TeX Live Manager and installer Next up was my own talk about beefing up the security of TeX Live by providing integrity and authenticity checks via GnuPG, a feature that has been introduced with the recent release of TeX Live 2016. The following discussion gave me several good idea on how to further improve security and usability. Arthur Reutenauer -The TeX Live M sub-project (and open discussion) Arthur presented the TeX Live M (where the M stands supposedly for Mojca, who couldn t attend unfortunately) project: Their aim is to provide a curated and quality verified sub-part of TeX Live that is sufficiently complete for many applications, and easier for distributors and packagers. We had a lively discussion after Arthur s short presentation, mostly about why TeX Live does not have a on-the-fly installation like MikTeX. I insisted that this is already possible, using the tex-on-the-fly package which uses the mktextex infrastructure, but also caution against using it by default due to delays induced by repeatably reading the TeX Live database. I think this is a worth-while project for someone interested in learning the internals of TeX Live, but I am not sure whether I want to invest time into this feature. Another discussion point was about a testing infrastructure, which I am currently working on. This is in fact high on my list, to have some automatic minimal functionality testing a LaTeX package should at least load! Kevin Larson Reading between the lines: Improving comprehension for students Having a guest from Microsoft is rather rare in our quite Unix-centered environment, so big thanks to Pavneet again for setting up this contact, and big thanks to Kevin for coming. Kevin gave us a profound introduction to reading disabilities and how to improve reading comprehension. Starting with an excursion into what makes a font readable and how Microsoft develops optimally readable fonts, he than turned to reading disabilities like dyslexia, and how markup of text can increase students comprehension rate. He also toppled my long-term believe that dyslexia is connected to the similar shape of letters which are somehow visually malprocessed this was the scientific status from the 1920ies till the 70ies, but since then all researchers have abandoned this interpretation and dyslexia is now linked to problems linking shape to phonems. Kevin did an excellent job with a slightly difficult audience some people picking about grammer differences between British and US English and permanently derailing the discussion, and even more the high percentage of typographically somehow specially tasted participants. After the talk I had a lengthy discussion with Kevin about if/how this research can be carried over to non-Roman writing systems, in particular Kanji/Hanzi based writing systems, where dyslexia shows itself probably in different context. Kevin also mentioned that they want to add interword space to Chinese to help learners of Chinese (children, foreigners) to better parse, and studies showed that this helps a lot in comprehension. On a meta-level, this talk bracketed with the morning introduction by Pavneet, describing an open environment with stimulus back and forth in all directions. I am very happy that Kevin took the pain to come in his tight schedule, and I hope that the future will bring better cooperation at the end we are all working somehow on the same front only the the tools differ.

After the closing of the session, one part of our group went off to the baseball match, while another group dived into a Japanese-style Izakaya where we managed to kill huge amounts of sake and quite an amount of food. The photo shows me after the first bottle of sake, while just seeping on an intermediate small amount of genshu (kind of strong undiluted sake) before continuing to the next bottle. An interesting and stimulating first day of TUG, and I am sure that everyone was looking forward to day 2.
