Journée mondiale IPv6

"Le 8 juin 2011 l'Internet Society (ISOC) organise une journée mondiale IPv6 pendant laquelle les fournisseurs et les sites sont encouragés à tester la technologie à grande échelle. Google, Facebook, Yahoo!, Akamai et Limelight Networks ont annoncé leur participation à cet événement." -- Wikipedia

C'est aujourd'hui !!!

Pour célébrer l’événement, j'ai décidé de configurer un tunnel IPv6 pour participer moi aussi au "test à grande échelle".

Vous n'aurez probablement pas besoin des opérations suivantes, mais si comme moi vous avez désactivé IPv6 il va falloir réactiver en modifiant les lignes suivantes (pour désactiver appliquez l'opération inverse) :

/etc/hosts
# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

/etc/modprobe.d/blacklist.conf
# Uncomment to disable IPv6
#blacklist ipv6

/etc/rc.local
#Uncomment to disable ipv6
#net.ipv6.conf.all.disable_ipv6 = 1
#net.ipv6.conf.default.disable_ipv6 = 1
##net.ipv6.conf.lo.disable_ipv6 = 1

Pour ceux qui utilisent Firefox comme moi, vérifier dans about:config que network.dns.disableIPv6 est à 'false'

Ceci étant fait, un reboot plus tard, l'exécution de la commande ifconfig
fait apparaitre la ligne tant attendue :
inet6 addr: fe80::221:5dff:fe46:1070/64 Scope:Link

Ceci étant fait mon Ubuntu est maintenant revenu à son état naturel et est en mesure de gérer l'IPv6.

Mon fournisseur d'accès ne m'offrant pas d'accès IPv6 natif, il me faut encore passer par un broker pour créer un tunnel.
Un ami (merci aanriot) m'a parlé d'Hurricane Electric (http://tunnelbroker.net/) je me suis donc inscrit, créé un tunnel
en clickant sur le lien idoine et généré les instructions nécessaires à la connexion au tunnel via l'interface du site :
ifconfig sit0 up
ifconfig sit0 inet6 tunnel ::216.66.84.42
ifconfig sit1 up
ifconfig sit1 inet6 add 2001:470:1f12:8c3::2/64
route -A inet6 add ::/0 dev sit1

Voilà ! Il ne vous reste plus qu'a vérifier que ça marche sur un site dédié :
http://test-ipv6.com/
ou

http://ipv6test.google.com/

Ça marche ? Maintenant vous pouvez dire fièrement :
IPv6 day ? J'y étais...

Change your Gogs admin password

I might have missed something, but I haven't found any simple way to change my admin password (with emailing not active) in gogs. It was quite easy to find the hash location, but as I didn't know how it was generated... Luckily I eventually found the parameters used, so here it is for you if you need them embedded in a script : var pbkdf2 = require('pbkdf2-sha256'); var key = 'YourChosenPasword'; var salt = 'AnyRandomValue'; var hash = pbkdf2(key, salt, 10000, 50); console.log(hash.toString('hex')); All I had to do was then to update the table user , setting passwd to the generated value (and updating salt with the value used in the script).

JavaScript for Perl lovers.

Article originally published on  Hello.js This time I feel really qualified to write this article because believe me, I love Perl ! I think in Perl, I dream in Perl, and I really appreciate the whole Perl community. I’ve been in love with this language for more than a decade but I decided that I needed a change. I’ve already said in a previous article why I chose to learn JavaScript this year (instead of getting involved in Perl 6 for example) but let me tell you why you might also enjoy learning JavaScript if you love Perl. Perl developers form a very unified community that all too often, resist outside influences, but learning a second language like JavaScript can really be a very enlightening experience. It’s expressive  JavaScript, like Perl, is an expressive language. You get your work done with just a few lines of code. When talking about programming languages, I really like the tent analogy: In a tent, you have functional things (tent fabrics) whose purpo...

What is the average salary for Perl programmers in 2020?

Original article published  my new blog   blog.assad.fr If I have no definitive answer on this, the  Business Insider  has some insights: HackerRank polled 116000 developers about their salaries and got interesting results: Perl is associated with an average global salary of $84,025.50 (54.2% higher than the global average salary) Scala is associated with an average global salary of $77,159.60 Go is associated with an average global salary of $72,691.30 Python is associated with an average global salary of $56,670.90 JavaScript is associated with an average global salary of $55,690 Without more information about the polled panel it's hard to state this results as “Truth” but they seems to confirm personal beliefs: The salary is more linked to the scarsity of resources than to the trendyness of the associated technology. Perl resources are less and less available. You know what ? It's good to be a Perl programmer :-)
