Go (Golang) for beginners


Because I might not be the only newbie in the Go world this year, I've decided to document here all the information I gathered.

Install Go

Go installation is pretty well documented on the  official Golang page but it can be summarized to:
  • Downloading the binary matching your OS and architecture from the golang download page
    wget https://redirector.gvt1.com/edgedl/go/go1.9.2.linux-amd64.tar.gz
  • Extracting the software (/usr/local/go seems to be the recommended location)
    tar -C /usr/local -xzf go1.9.2.linux-amd64.tar.gz
  • Creating your Workspace
    Go workspace is the place where you put your source code and where the go packages/tools will be downloaded.
    mkdir $HOME/go
    In this directory, create a src subdirectory where you'll place all your code.
    mkdir $HOME/go/src
  • Setting the environment variables
    Setting  GOPATH (export GOPATH=$HOME/go) to point to your workspace.
    Then your path PATH (export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin) 
    • For a system-wide configuration:
      in /etc/profile
    • For a per user configuration:
      in ~/.profile

Editor configuration

If you use vim as I do, you might want to use vim-go or vim-polyglot and read the vim-go tutorial.
But if it's not your case, your solution is probably on the page about the IDEs and editor plugins for Go.

So much more to explore

With this (basic) setup I'm now ready to go further 
  • Setting up Go in docker
  • Do some datascience
  • Unleashed goroutines/channels power
  • ...
But that will be in another post :-)

Resources

There are of course many more useful resources to start with.
But I hope the following ones will be as useful to you as they were to me.

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
