Today I want to present an open source software created for the asset management OCSInventory, and in the next days i want to post information about Fusioninventory and GLPI. I will focus on programs that allow you to have an inventory of your hardware and software that allow you to manage everything with discovery tools, reports and alerts, but first let’s see what’s the mean of Asset Management:

Most of Italian people that use the world wide web are daily in the Cloud, without knowing it. Only 15% of internet users know that that “putting online something” means sharing it in the Cloud, while 38% know that they have used at least one of the Cloud services. Rather, when talking more technically, one discovers that 88% of web users meet more than once the Cloud in its life in a completely unaware way.

Linux and Windows. It’s like comparing Apples and Oranges. Software can be compared, but how do you do so fairly and honestly? And what sort of presumptions should I make concerning where the reader of this article stands? I presume you are among the “rare” Linux users.

Not easy at all. Let’s start of with where I come from. I use Linux because I really prefer the stability and security of the platform. My system’s performance is better.. Hands down Linux is much better than any flavor of Windows in those three categories. But then there’s the software issue.

I’m going to compare software simply on a “Does it do the job?” and is there a Linux equivalent, or how close to equivalent they are.

There are many occasions where you need to create connections to machines and services that are protected by firewalls because it is appropriate to adequately protect them, but for which the creation of a VPN becomes an excessive burden. For this reason, the ability to port forwarding via SSH is very useful for creating an encrypted tunnel from one machine to another, allowing you to enable only local access (such as a MySQL only listens locally) safely, with the only the problem that in case of problems, the SSH connection (and its tunnels) could fall.

Have you ever wondered what that bright object in the pre-dawn morning was that you couldn’t help notice? Or is that reddish star Mars? Is that fuzzy mass of white a wispy cloud or a galaxy?

Note the time you saw the object and where you saw it (towards the east near the horizon, for example) and Kstars will tell you what the object is. Kstars is a desktop Planetarium that will open the heavens to your understanding.

Kstars is of course, open source. It can be installed on most Linux systems either alone or as part of the kdeedu (KDE Educational) package. It will run well enough on a Pentium IV while using only 80 megabytes of RAM but it’s really spectacular running on a multi-core system with several gigabytes of RAM.

If you’ve ever owned a Windows computer chances are your computer was at one point infected with a virus. The solution to this problem is not purchasing antivirus software. The answer to this problem is abandoning Windows as your main operating system, however to some this might seem an impossible thing to do. Apple computers are rather expensive and while they can run Windows as a secondary operating system most people would prefer to be able to run Windows applications on their primary operating system without a noticeable slowdown

t’s some time that i don’t do a roundup of games, and so today i want to present you some of the best FPS available for Linux. Like i always say, the time where Linux games were not comparable with the Windows counterpart is past, and now , with the right hardware, you can play some great games also on your Linux box.

Let’s take a look at : Warsow, World of Padman, Urban Terrror, Open Arena and AssaultCube

During May’s Google IO developer conference, the first netbooks using the Linux-based ChromeOS were announced from Acer and Samsung. This was a public follow up from the very public beta of ChromeOS netbooks kicked off in December. One of the morning keynotes was dedicated to describing the new netbooks and their features. In June, the ChromeBooks finally shipped and were available for purchase from Amazon and Best Buy. Amazon actually sold out of Samsung Chromebooks in the first week.

An important field where GNU/Linux is gaining ground is that of schools, both primary and secondary. I think it’s important to teach children and young people that there is a whole world of open source software to explore, and that not everything that is connected to a computer means Windows and/or proprietary systems. There are specialized distributions to help teachers in making their students know at this world, in this article we’ll see an overview of these distributions.

After the update to Ubuntu 11.10 my wireless goes up and down, and so i’m trying to debug this problem looking into dmesg.

But this brought me to another small issue, dmesg prints timestamps in the form of seconds.nanoseconds since the system booted. And no, there seems to be no -h option to make it human readable. so you should check your boot time and make some calculations to see where the events logged are happened.

This don’t seem so useful ! Let’s see how to have these information in a better format.

Just over a year ago the open source Office Suite world was disturbed by indecision, much the same way world stock markets have been upset by uncertainty today. Oracle had purchased Sun Microsystems and with it the “ownership” of the open source office suite OpenOffice.org. Being unsure of what Oracle would do with OpenOffice.org a number of the key developers at OO.org left and formed the Document Foundation. They named their fork of the OO.org code “LibreOffice”. “Libre” meaning “little or no restriction.”

I’ve recently discovered another useful package for GNU/Linux, Littleutils. The littleutils include a duplicate file finder (repeats), image optimizers (opt-jpg opt-png opt-gif recomp-jpg), file rename tools (lowercase uppercase), archive recompressors (to-bzip to-7zip to-lzma), a tempfile utility (tempname), all are small programs that do just 1 thing, in a perfect Unix style, so don’t expect anything too complex but these small gems can save you some time to do specific jobs.

Bash is the default scripting language in most Linux systems. Its usage ranges from an interactive command interpreter to a scripting language for writing complex programs. Debugging facilities are a standard feature of compilers and interpreters, and bash is no different in this regard. In this article, I will explain various techniques and tips for debugging Bash scripts.

The command line is a powerful way to interact with a Linux computer. Instead of using the mouse, you just type commands into the shell. (The shell is a blank window where you type in your commands.) So for example, instead of clicking on your file browser, you simply type ls [enter] to display the contents of your working directory.

There are several different shells. The original shell is sh, or the Bourne Shell. It was developed by Stephen Bourne at Bell Laboratories. It’s still in use today. Check for it in your /bin directory.

gEdit is a serious text editor in the tradition of many editors that the programmer or code jockey will appreciate – syntax highlighting in many source codes, script formats, markup formats, and even some Scientific formats.

I write a lot of HTML code and I find the multiple undo/redo, find, search & replace, and the built-in code-aware spelling checker essential on a daily basis.

There are many reasons I prefer Linux. Near the top of the list is that I’m a tweaker. Someone who enjoys making changes and having things “My Way”, like the song by Frank Sinatra. Linux has many configuration files, most of which “lurk” in the “/etc” folder. These files are used to configure the mounting of drives, network lists like what IP address goes with what computer name, passwords and admin access, application configuration and even what the boot menu looks like. “Under the Hood” Linux is highly customizable.

Gnucash is a great tool to keep the budget of the family, and from the version 2.4.0 supports connection to a database, SQLite, MySQL or PostgreSQL for data storage. Using a local database, however, tie to a specific computer for its use. Instead I want to be able to open a GnuCash session from any computer and connect to a single, remote, database.

Enable remote connections to the database from the whole net is very unsafe, but a SSH tunnel gives me a lightweight and reliable alternative .

I’ve already talked about fail2ban and logcheck, 2 tools that can scan your logs and do actions, based on rules that you can give/modify, usually modify your iptables rules to stop active attacks against your server or simply send you a warning if some thing is found in the logs. Today we’ll see a similar tool, sshguard, it is different from the other two in that it is written in C, so it’s uses less memory and CPU while running, but still achiving the same results.

The organizers of Humble Indie Bundle today announced a new initiative on humblebundle.com, which allows anyone to buy Voxatron, an unreleased indie game for the PC at the price that you want. Voxatron, it’s at this time in Alpha stage, this game is a platform shooter retro-style, with more than 20 rich areas of enemies to defeat. The game is available for Windows PC, Linux and Mac, DRM-free, and with the guarantee that all future updates will be completely free.

Games are always popular among all age group. With each passing day, new technology is being developed and with new technology, new games and new platforms are also being developed. One such platform is the Android operating system which has been developed by Google to work for smartphones. A large number of developers are involved with the development of applications based on this platform. Even many new Android games are also being developed day by day. These Android games and apps are either free or paid and can be downloaded or bought from Google’s online app store Android Market. Even there are many third party online stores where the Android games and apps can be obtained.
