Ruby 2.0 is out!

mruby – Lightweight Ruby

What is mruby ?

mruby is a light weight implementation of the Ruby programming language.

So if you use ruby then mruby might be useful for you – because it can run ruby program in interpreter form or compile and execute in vm form, probably in less amount of time (faster execution) with less amount of resources (that’s what the light weight indicates) as compared to the standard Ruby (MRI).

Ruby is already popular in web application development (Ruby on Rails framework) but the lightweight and efficient version of ruby would probably explore new domains for ruby – e.g mobile platform (Actually, it has started – checkout the bottom notes), embedded devices etc.ruby-logo


Download mruby

There isn’t any official version of mruby available right now but you can checkout the github page for downloading the initial release.

mruby at github

Notes : Now, Ruby is one of the most popular programming languages, within a few months you might be able to write mobile apps for Android and iPhone, in ruby using mobiruby (built on the top of mruby).


Mosh – The New SSH!

Mosh (Mobile Shell) is a terminal application similar to SSH but it’s more robust, responsive and of course it’s mobile i.e it allows roaming (you will be connected to your server even the network/IP Address changes).

Mosh is a free software (available under GPL, hosted at GitHub) available for GNU/Linux, FreeBSD and Mac OS X. So you might be thinking that it’s a good replacement for ssh protocol – you’re right, in fact it is. So next time you login to your remote server then don’t forget to give it a try!


Why should you try Mosh (over SSH) ?

  • It’s faster (no network lag)
  • more robust
  • no special privileges (superuser/root) is required
  • designed from scratch for Unicode
  • same login method (using public key or password)

How to Install Mosh in Ubuntu

Ubuntu 12.04

In Ubuntu 12.04 LTS – it’s already there in the official package repository, just execute –

sudo apt-get install mosh


Older versions of Ubuntu i.e 11.10/…

$ sudo add-apt-repository ppa:keithw/mosh
$ sudo apt-get update
$ sudo apt-get install mosh

Top 10 Most Popular Programming Languages of 2012

Are you an absolute beginner who wants to get started with programming or an expert one interested in trying new cool languages – you may find a great one from the top 10 list of programming languages which are popular now (it’s based on a recent Hacker News Poll about the favorite programming language, a couple of days ago). e.g if you’re new to programming – Python would be a great to begin with, on the other hand if you’re bored with imperative languages like C, Java etc then try something different – such as Haskell.

Some of the new programming languages has gained a lot of popularity – Scala, Haskell, Clojure, Erlang, CoffeeScript (similar to JavaScript, good for ruby programmer who want to write JavaScript in ruby way); specially the function programming languages like Haskell(appears in top 10). Scripting languages are on top, Python (1st) and Ruby(2nd) became more popular (while PHP and Perl seems to be loosing its popularity, although it’s a different fact that PHP has most of the share in server side language).
