NOKUBI Takatsugu: Virtual Background using webcam

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:

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

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.

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.

NOKUBI Takatsugu: 120th Tokyo area debian seminar

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.
