Installation locale de nodejs et npm


Pour mes environnements de développement je suis un fan des environnements locaux
(perlbrew/plenv, virtualenv...) :
_  Pour séparer mon environement de développement du sytème
_  Pour se dispenser du sudo
_  Parce que ça donne une meilleur visibilité sur l'environnement de dev qui est ainsi mieux contenu/localisé.

C'est pourquoi comme je vais désormais utiliser assez souvent node et npm, je préfère le mode d'installation suivant à celle classique des paquets sur ma Debian.

# Installation des prérequis (optionnel)
sudo apt-get install build-essential curl

# Ajout d'un répertoire au PATH
mkdir ~/local
echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc
. ~/.bashrc

 # Installation de node via les sources
mkdir ~/node-install
cd ~/node-install

 # Pour choisir la version (idéalement LTS)
# https://github.com/nodejs/LTS

curl http://nodejs.org/dist/latest-v4.x/node-v4.5.0.tar.gz | tar xz --strip-components=1
./configure --prefix=~/local
make install
cd ..
rm -rf  ~/node-install

#Installation de npm
curl https://www.npmjs.com/install.sh | sh


Update (22/08/2016) :  Changement de node-latest.tar.gz vers la version LTS  v4.x (latest-v4.x/node-v4.5.0.tar.gz) car la version bleeding edge m'a causé trop d'incompatibilité.

 Update (03/04/2017) : Ajout du lien vers la roadmap des versions avec les infos sur les LTS

 Update (27/08/2017) : J'utilise de plus en plus la méthode d'installation par packets (https://nodejs.org/en/download/package-manager)

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).

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 :-)

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 purpose is to provi
