Grep is the best tool to search in big file for a specific pattern, or a specific process in the complete list of running processes, but it has a small limit, it searches for the exact string that you ask, and sometime it could be useful to do an “approximate” or “fuzzy” search.

For this goal the program agrep was firstly developed, but it’s closed source, but luckily there is an open source source alternative: tre-agrep

Many security policies require you to change the port number of the SSH service to ensure greater security in a Linux system. Situation now used throughout the IT world and used mostly by users who have their own private server. Today I want to show you how to add another security layer without having to change the SSH port. To do this we’ll incorporate the famous Google Authenticator to our ssh service, in this way we’ll have a safe, two steps security, by entering our password and the combination given from the GA application. Let’s see how to do this…

A few months ago I switched from Gentoo to Arch Linux as Linux distribution on my PC at work, and at the moment I am very happy with this distribution, but there is to say it is not so easiest to use for newcomers to the Linux world and so they typically approaches the most popular and user friendly Ubuntu.

This is the second part of my article on my favorite games released for Linux in 2013, this is the list of my personal top 10.

I was searching for lightweight collaboration suite (messaging and groupware) to manage some small websites and while searching around I found Citadel. Citadel is a complete and feature-rich open source groupware platform.

This has been in my opinion the first real year, and hopefully this will continue, for gamers on Linux, this is due to a massive investment by Valve in bringing the Steam platform on Linux systems and their planned Steam OS, that will be based on Linux.

his is my vim configuration to work with Git + Puppet manifests, mostly it’s based on some good articles about this that I found online:

Using vim and Debian to do puppet development Puppet editing like a pro Using Vim to edit Puppet code Using this repository you’ll enable the following plugins:

pathogen Makes it super easy to install plugins and runtime files in their own private directories. snipmate.vim snipMate.vim aims to be an unobtrusive, concise vim script that implements some of TextMate’s snippets features in Vim. syntastic Syntastic is a syntax checking plugin that runs files through external syntax checkers and displays any resulting errors to the user. This can be done on demand, or automatically as files are saved. If syntax errors are detected, the user is notified and is happy because they didn’t have to compile their code or execute their script to find them. tabular Sometimes, it’s useful to line up text. Naturally, it’s nicer to have the computer do this for you, since aligning things by hand quickly becomes unpleasant. vim-puppet Make vim more Puppet friendly! vim-fugitive Provides an amazingly deep Git integration for vim.

While I was looking some video related to Linux I’ve found this video of gotbletu an user that I follow on Youtube, related to a small player to listen music directly from the terminal: pms AKA Poor Man’s Spotify.

I like lightweight clients, and so I’ve gave it a try, these are the results.

Recently I’ve discovered this project that has great ambitions:

arkOS is an open-source platform for securely self-hosting your online life.

Everything started from the founder Jacob Cook and the CitizenWeb Project he founded. It’s designed to run on a Raspberry Pi – a super-low-cost single board computer – and ultimately will let users, even of the non-technical variety, run from within their homes email, social networking, storage and other services that are increasingly getting shunted out into the cloud, and so under the control of big companies.

So in short arkOS is a lightweight Linux-based operating system that runs on a Raspberry Pi.

Faster Than Light (more commonly known as FTL) is a top-down, real-time strategy game on Steam, made by indie team Subset Games. The player takes control of the crew in a space vessel that’s in possession of critical information that must be delivered to an allied fleet several sectors away.

Linux is much better at multitasking processor-intensive tasks than Windows. I remember how virus scanning used to make by old Windows PC almost unusable. Linux is much better, but sometimes bad things happens ! Perhaps a plugin of your browser is using all the CPU, or some bad software is freezing your system, or Apache it’s eating up all your resources on your server.

If you have seen some situation like these, don’t worry anymore, you don’t need to kill all the offending processes, restart your graphical session, or even worse restart the computer, you can simply put the specific process in “PAUSE” and analyse the situation, in some cases you could find the cause of a poor performing process, or just restart it in a second moment, maybe after you have saved all your works, when you can give to that process all the CPU.

In this post I want to show the steps you must follow to have a Development Environment for Android in your Linux distro.

You might not have noticed that the $35 computer, Raspberry Pi has exceeded 1 million units shipped. Further, they have production volumes cranked up to the point where you can order more than one unit.

As system administrator, or simple user that uses Linux on its desktop sometime you notice that something it’s eating all the memory of your system. As first thing be sure to understand how Linux manage memory, I’ve be called too many time by scared users that did a free and were unable to read its output properly, in short, don’t worry if the Linux Kernel it’s using your memory to cache file.

So let’s take a look at a nice small program that can help us in find which process/users are using, for real, the memory of our systems.

Starting an online business can be a daunting task. Once you determine the products or services to sell online you must then select the method to reach the customer and collect payment. As an online merchant your can choose to sell on one of the community based web portals like eBay or yahoo store. However, if you decide to operate your own domain, so you can build brand and company loyalty, you will require a website and shopping cart with an integrated payment gateway.

BitTorrent Sync by BitTorrent, Inc is a proprietary peer-to-peer file synchronization tool available for Windows, Mac, Linux, Android, iOS and BSD.

Some days ago Valve announced it’s new, and not so secret, project SteamOS : “Thousands of games, millions of users. Everything you love about Steam. In short, soon there will be a new Linux distribution tailored to get the max from Steam and its games.
