Google, your IPv6-related email restrictions suck
After years of waiting, Google has finally enabled IPv6 for their email service Gmail. And a few weeks ago, they updated their policy, adding one specific rule: reject email from IP addresses with no reverse name:
% nc -Cv gmail-smtp-in.l.google.com. smtp Connection to gmail-smtp-in.l.google.com. 25 port [tcp/smtp] succeeded! 220 mx.google.com ESMTP bz2si13656083wjc.108 - gsmtp HELO boo.example.com 250 mx.google.com at your service MAIL FROM: <me@example.com> 250 2.1.0 OK bz2si13656083wjc.108 - gsmtp RCPT TO: <you@gmail.com> 250 2.1.5 OK bz2si13656083wjc.108 - gsmtp DATA 354 Go ahead bz2si13656083wjc.108 - gsmtp Subject: Test From: Me <me@example.com> To: You <you@gmail.com> Test. . 550-5.7.1 [2001:db8:8e3f:43c7::12 16] Our system has detected that this 550-5.7.1 message does not meet IPv6 sending guidelines regarding PTR records 550-5.7.1 and authentication.

WebPG, a PGP addon for web browsers
Classified in : Homepage, Debian, To remember
One problem with PGP, at least with GnuPG, is that it does not interact with the web. There used to be a Firefox addon for that, called FirePGP, but its development was stopped.
So, good news, a new addon has come to fill the gap it left: WebPG, an addons for Firefox and Chrome. I am using it since a while, and it seems to work fine, being able to encrypt, sign, decrypt and check text blocks. Of course, it cannot handle PGP/MIME unless explicitly adapted to the webmail you use, but there seem to be some experimental support for GMail.

Google, FAI anti-neutralité (MàJ : plus maintenant !)

Mise à jour : les conditions d'utilisation de Google Fibre ont visiblement été mises à jour, et ne mentionnent plus cette clause infâme.
Des clauses anti-serveur
En France, parmi les grands fournisseurs d'accès, Numéricâble se démarquait par une clause particulière dans ses conditions d'utilisation : l'hébergement d'un serveur était considéré comme une violation de contrat, passible de déconnexion immédiate. À ce jour, cette clause semble avoir été retirée.

grep --only-matching
Classified in : Homepage, Debian, Command line, To remember
grep is designed to print lines matching a given pattern, but I often need to print only the matching part, discarding the remaining.
I used to do that with sed, but it involves several actions: match, replace the line by only the matching pattern and print. Fortunately, GNU grep has an option to do just that:
-o,--only-matching- Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.
Unfortunately it is not a standard option, so it may be missing on non-GNU systems.
