TL;DR - Open Source Security, Inc. no longer releasing open source software: https://grsecurity.net/passing_the_baton.php …
Open Source Summit Japan 2017 でGentooの発表することになりました．
#OSSummit @Gentoohttps://ossjapan2017.sched.com/speaker/aliceferrazzi …
The blog as been moved ? here:
Still not sure if the move will be temporary or not.
So for now I will keep both the Blog.
Many people came to the Gentoo booth,
mainly students and Open Source users
asking for Gentoo information.
We gave away around 200 flyers, and
many many stickers during the two days.
Unfortunately the sticker we ordered
from unixsticker had some SVG problem.
We had also in exposition some esoteric
enviroment like the IS01 sharp,
off course mounting Gentoo as Native and
Of course one of the first things we tried
was the 5 minutes long Gentoo sl command.

We also had a Gentoo notebook
running wayland (the one in the middle).
It was an amazing event and I would
like to thanks everyone that came to
the Gentoo booth, everyone that helped
making the Gentoo booth and all the
amazing Gentoo community.

Why package is anyway deciding to automatically not fixing dependency maybe because trying to fix all the dependecy will not work correctly When portage have conflict for many package it became more complicated and we will have a command similar to this: --reinstall-atoms="A B C D E F G H I L M N ..." For solving such problem there is emerge --reinstall-atoms wrapper https://github.com/naota/emerge-wrapper - automatically fixing circle dependecy - showing dependency graph - there is also a function for make try the dependency graph in a container - emerge analyzer tool
Recently i became Gentoo Kernel Project member, maintaining the Gentoo Kernel branch 4.7
I already made some release.
so you can ping me,
if the Gentoo Kernel is not up to date
Recently we had the Dirty COW (CVE-2016-5195) kernel vulnerability come out,
and the Gentoo 4.7 branch update was released after just some couple hours after the kernel patch was release.
School exam are almost finished.
I could give 20 class in one semester and get 37 school point.
in this second semester i need around 10 point for get in 4 year and start doing mainly research.
Because i had some free time i got to internship for look for work and did Gentoo Study Meeting, after almost 6 months.
And contribute on Gentoo.
I also could get into the open source research lab of school,
so in this months i will follow some few lessons and do opensource research.
The development as been a bit slowed down because of University exam of July and August.
It will continue soon.
This next month i will have a new University exam, so i will be more slow on replay about eisen, i will try anyway to keep a high quality.
I'm unfortunatly, from my prevision, taking more time for building a user friendly virtual image for problem with vagrant on cygwin.
tomorrow i will be at women techmakers tokyo and i will available for any question.
after tomorrow i will do a little presentation of eisen engine at tokyo pyladies.
Don't commit generated files
Today I started from css, at first we introduced it with the generated files, but now that we are using vagrant for developing such files are not needed and dosen't have to be maintained under a revision system as best practice.
instead the vagrantfile now is containing a simple
echo -e "\n--- Updating css ---\n"
gem install compass
After finishing to autocreate the css file i moved to make the init service.
At first like I said in the previous post i thought to use supervisor, but i got into a problem, supervisor is requiring to specify the enviroment variable, and celery+ansible was claming about such call. giving a "muxserver_listen bind(): Operation not permitted" error.
so i used instead LSB-init and all started to work.
you can see all the file here
Because of this, I'm starting to make actual releasing box using
vagrant package --output eisen.box
And if I'm not too late happy pi day #piday from eisen
This week was a also enough busy, studying for exams.
Anyway now i have a bit of freetime and I'm going on developing eisen.
As now I'm trying to make the init file for autostart eisen front and eisen engine using supervisor and making translation in English and Japanese for gettext.
The news of this week are:
- Added the freenode channel #eisen
- Added explanation about cloning git repository before using vagrant up (thanks to ytooyama)
- Added language switcher in the Settings options
- Fixed the recipe and tasks modals
- Added recipe registration
- Adding the Host Manager as active by default.
- Creating the DB for monolog at DB creation.
- Fixed bug on adding recipe
- Added recipe example for testing
I come back from a school trip in Gunma,
and started to get up with eisen issue,
but i will be busy studing until 03月08日 because of a school exam.
please be free to try Eisen with also different browser and open a bug request if there is any problem
If you find any issue with Eisen Front or Eisen Engine,
please submit a bug report
If you want to contribute,
check the contribution section in the Documentation
For Eisen Installing information please check the Documentation
From 23 to 29 I will be in nagano, so I probably cannot get up with eisen issue this week,
but i will enjoy a bit of snow after many months of just studing and coding
and if you are not afraid to touch the code,
you are anyway welcome to help opening issue and sending pull request:
or send message to twitter:
If I have bandwith I will anyway try to replay to issue question
in the mean time please enjoy some screenshot:
We also made amazing sticker for your notebook.
Get yours at "オープンソースカンファレンス2016 Tokyo/Spring" Eisen booth.
