It is similar to #1000810, but it is already closed. My solution is:

• apt remove mailman3-web
  • keep db and config files (do not purge)
• apt autoremove
  • remove django related packages
• apt install mailman3-web mailman3-full

I tried to send to the report, but it rerutns 550 Unknown or archived bug

I made a webpage to produce virtual background with webcam. https://knok.github.io/virtbg/ Sorcecode:
https://github.com/knok/knok.github.io/tree/master/virtbg Some online meeting software (Zoom, Microsoft Teams) supports virtual background, but I want to use other software like Jitsi (or google meet), so I made it. To make this, I referred the article Open Source Virtual Background .
The following figure is the diagram.

It depends on docker, GPU, v4l2loopback (only works on Linux), so I want to make more generic solution. To make as a webpage, and using OBS
Studio with plugins (obs-v4l2sink, OBS-VirtualCam or OBS (macOS) Virtual Camera) you can use the solution on more platforms. To make as a single webpage, I can reduce overhead using inter-process commuication using http via docker. This is an example animation:

Using jisti snapshot:

Unfortunately, BodyPix releases only pretraind models, no training data. I need more improvements:

• Accept any background images
• Suppot choose camera device
• Useful UI

I had attended to Tokyo area debian seminar #157. The day s special guest is Chris Lamb, the Debian Project Leader in 2017. He had attended to Open Compliance Summit, so we invited him as our guest. The following pdf file is the day s presentation:

• http://tokyodebian.alioth.debian.org/pdf/debianmeetingresume201711-presentation.pdf

And Hideki Yamane(henrich) talked about a new idea of Debian distribution fresh , pull-based rolling release. The details would be published by him in a few days. There were some discussion, and we need to introduce more information aboud Japanese Debian/FLOSS scene, so now I am writing this article. Anything else, I ccould get good time with debian developers and community. Our community, especially in Japan, requires more new commers, young people.

Now I am helping to maintain uim-package. It is splited into too many packages (over 40, including dbgsym). Working status is written as the debian wiki entry https://wiki.debian.org/JapaneseEnvironment/Uim. Currentry it is not finished, when I ve done all of them, I ll upload them to experimental.

According to my follower s tweet:

The typhoon image and horizontal flipped Debian logo looks same.

I made a simple implementation of text classification with Recurrent CNN. https://github.com/knok/rcnn-text-classification It uses chainer, a Deep Learning framework. Recurrent convolutional neural networks for text classification

I attended GAME-ON last weedkend at Miraikan, The National Museum of Emerging Science and Innovation in Tokyo. There are many historical videogame hardware and software, and the bland-new PSVR exibition. I can see the real DEC PDP-1 hardware. Unfortunately it is only haredware, not worked. And also PONG is exibited. There are many old hardware Atari 2600, Commodore 64, Spectrum, and so on. Almost exhibition with English description, and officials can talk English, if you feel interested, go Miraikan until 30th May.

I watched PIXELS in a theater. It subjects about video games, mostly retro 80 s arcade games. I love video games from childhood, my first game played would be Taito s Space Invaders, I was the 4 or 5 yeas old time. It had bring me to the computer world. Fortunately I am working at Akihabara area, so I can play the video games in the movie like Pac-man, Glaga, Cemtipede, Donkey Kong and so on in two gamecenters, Natsuge Museum and Hey (Hirose Entertainment Yard . Natsuge Museum is under private management so it closes week days. They focused to old games between 70 th to 90 th. Hey is a franchised shop ownd by TAITO. They covered almost video games except medal games. You can play old games like Paper-boy, The Tower of Druaga, and newest games like Left4Dead arcade. They correct many titles of the games in the movie, and be playable. They are my recommended place in Akihaba, if you like video games.

This month, I changed FTTH Internet from 100Mbps to 1Gbps. The costs is almost same as the past line. To change the line, I had need to be witness in the construction, so I couldn t get time to attend DebConf 2015. According to Speedtest.net, I can get about 300 Mbps upstream bandwidth.

I tried to install Jessie on a brand-new virtual machine (kvm), but it has a problem about serial console login. At least, wheezy installer worked fine because it adds getty entry on /etc/inittab. Jessie uses systemd but no care about getty service for serial console. The probrem is reported as #769406. My solution is invoke systemctl enable serial-getty@ttyS0.service via ssh.

Graham Neubig published Travater , an OpenSource statistical machine translation system and the demosite (http://ahclab.naist.jp/travatar/translator/). Graham said It makes good result likely Google Translation. Unfortunately, it seems to be crwoded, so I can t get correct result (output IO Error dialog). Anyway, it is a good new for Japanese processing scene.

A presentation slide, named Attacking against 5 millions SSH public keys 500 SSH is published, it is a lightning talk in Edomae security seminar in Jan 24, 2015. He grabbed ssh public keys with GitHub API (https://github.com/$ user .key), the API is obsoleted, but not closed. He found short (<= 512 bit) DSA/RSA keys and can solve prime decomposition 256bit RSA key in 3 seconds. And he repoted there are 208 weak ssh keys generated by Debian/Ubuntu (CVE-2008-0166). It was already announced by GitHub. On the other hand, such ssh keys couldn t solve prime decomposition with fastgcd. It means almost ssh keys in GitHub has no bias in almost random number generators implementations, it is a good news.

I tried to make Google::API::Client deb package, it requires Module::Build::Tiny, and dh-make-perl don t suppot it, so I worte a override code in debian/rules. [sourcecode]
override_dh_auto_install:
./Build install destdir=$$(pwd)/debian/$pkgname installdirs=vendor
[/sourcecode] More elegant answer should be to add Module::Build::Lite support to dh-make-perl. Update: This probrem is only wheezy, I don t need such workaround on sid. Thank you greoga.

In Japan, winter holiday is a special for many people, they go back to their hometown, and take a time with family. Of cause, I do too. Last weekend I went back to Nagoya and now I still in there. Tomorrow I ll go to Tokyo and work after this weekend. Many asian countries have same practice, but almost celebrate the lunar(Asian) New Year. Some countrysides in Japan people also celebrate the luna New Year, but not major in Japan. I can take a good holiday, and I hope this year is good for everyone.

I had attend 120th Tokyo area Debian seminar at Shinjuku. An attendee brought hp Jornada 780 and tried to install Debian, so I helped him. Using a kernel, boot loader and userland from Lenny on j720 page and it worked fine, except PCMCIA NIC. His NIC is Corga PCC-TD is not listed in /etc/pcmcia/*. I didn t have enough time to write it, so I couldn t check it. However, later releases after Lenny don t have arm architecuture, so it should be hard to upgrade it. I don t know recent Linux kernel work on Jornada 780. The configuration and code for jonrnada 780 are still in the kernel, but it wouldn t be tested anyone.

Last weekend, I (knok), Hideki (henrich) and Yutaka (gniibe) met with John Paul Adrian Glaubitz (glaubitz). In the past, I had met with another Germany developer Jens Schmalzing (jensen) in Japan. He was a good guy, but unfortunately he gone in 2005. I had an old OpenPGP key with his sign. It is a record of his activity, but the key is weak nowaday (1024D), so I stop to use the key but don t issue revoke. Anyway glaubitz is also a good guy, and he loves old videogame console. gniibe gave him five DreamCast consoles. I bring him to SUPER POTATO, a old videogame shop. He bought some software for Virtual Boy. DebConf 2015 will hold in Germany, I want to go for it if I can.

I attend 10th Kernel/VM Explorers (Japanese page) in Sun May 25 at Jinbocho, Tokyo as a audience. The event awards The Most Insane Presentation to @kanorimon. Her presetation was Implement PDP-11 interpriter . The implementation is written by Java, and it works to build UNIX V6 itself, yes it is really insane. She may be 19th or 20th (collage freshwoman), I can feel the future. Update: Many photos are available: https://plus.google.com/photos/109141856943098831842/albums/6017204632570043713

At last weekend, I attended to Kanto LibreOffice Hackathon (Japanese). I could made two achieviements.

• Manpages for Namazu related commands
• Japanese rules for LanguageTool

Any event is a good trigger for me.

KAKASI 2.3.5 had released. The previous release was over 10 yers ago. In 2006, I tried to release 2.3.5, but I hadn t to complete relase jobs. However almost jobs were finished, so it was easy to release for me. But some bugs are discovered so I ll release 2.3.6 in a few days.

I attended the 1st Debian mokumoku meeting. mokumoku ( ) means silently and concentrativeness in Japan. There were about 6 people in a room. I tried to prepare release of Namazu and KAKASI.
