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.
There isn’t any official version of mruby available right now but you can checkout the github page for downloading the initial release.
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)
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
In Ubuntu 12.04 LTS – it’s already there in the official package repository, just execute –
The Advancement of Free Software Award => Matz (Creator of Ruby)
The advancement of Free Software Award is given(once in a year) to someone who made a great contribution to the progress and development of Free Software. This year, the award has been given to Yukihiro Matsumoto (Matz), the creator of Ruby programming language.
Matz got the award for the advancement of Free Software (by Richard Stallman (aka RMS, St. iGNUcius), founder of FSF) for his contribution to various GNU projects, Ruby (one of the coolest programming language (an scripting language like python), recently it has become much popular in web development due to Ruby on Rails framework) and other free softwares projects.
The award for Project of social benefits => Luis for GNU Health
The award for project of social benefits is give to a project or team or the ideas of the free software movements which intentionally or significantly benefits human society in other aspects of life.
This year, the award goes to GNU Health, a free software projects that works with health professionals around the world to improve the underprivileged. The president of GNU Solidario (the organization behind the GNU Health project) => Luis Falcon got the award by Richard Stallman for his great contribution to the society (through the free software project).
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.
Top 10 Programming Languages (in the order of Decreasing popularity)
Python (Most Popular) : 3026 points
Ruby : 1697 points
C : 959 points
C# : 814 points
PHP : 647 points
Java : 544 points
C++ : 526 points
Haskell : 510 points
Closure : 449 points
Data Source – Hacker News Poll about the favorite programming languages, although there was more than just the 10 programming languages but I’ve shorted the list to top 10. Points are basically the thumbs up vote or +1 or like.
XBMC version 11.0 EDEN has released! If you’re already using XBMC on Ubuntu 11.10 or 12.04 (or older versions) then you may update it, on the other hand if you haven’t tried it yet, then give it a try! It’s the coolest Media Center.
