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.

It's not often we hear from Pat Volkerding but HPR posted a rare audio interview with him that reveals not only how he develops Slackware, but blows the top off of Time and Space in the meantime.

After yesterday announcement, several more security vulnerabilities were discovered in the Linux kernel packages, this time affecting the Natty backport of Ubuntu 10.04 LTS.

Is this PowerPoint’s Revenge? A 29-page slide deck – made public this week in Microsoft’s patent lawsuit against Barnes & Noble — outlines, in great detail, the bookseller’s objections to the software company’s campaign to collect patent licensing fees from Android device makers.

The Binding of Isaac, this FUNtastic game from the twisted minds of Edmund McMillen and Florian Himsl, is now available as a time-limited offer you can refuse.

IP attorney Edward J. Naughton is repeating his arguments that Google's use of Linux kernel header files within Android may be in violation of the GNU General Public License (GPLv2), and tries to discredit Linus Torvalds' thoughts on the matter along the way. Naughton, or the clients he may be representing, seems intent on trying to cast doubt on the legal framework upon which Google's Android platform rests. To that end, Naughton has released a detailed whitepaper containing what he claims are more examples of the kind of problems he's been pointing out. Here's the basic premise of Naughton's arguments:

Fabio Erculiani proudly announced last evening, November 9th, the immediate availability for download of three new Sabayon Linux 7 editions, for the LXDE, Enlightenment 17 and Awesome desktop environments.

The Wine development release 1.3.32 is now available.

BitTorrent Inc. promised last year, when they released the uTorrent Server for Linux, a client version of the extremely popular uTorrent torrent downloader.

This tutorial shows how to prepare an Ubuntu 11.10 (Oneiric Ocelot) server with nginx for the installation of ISPConfig 3, and how to install ISPConfig 3. Since version 3.0.4, ISPConfig comes with full support for the nginx web server in addition to Apache, and this tutorial covers the setup of a server that uses nginx instead of Apache. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: nginx and Apache web server, Postfix mail server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more.

This is how I generally setup a new debian server or vps. This process normally only takes a few minutes to have a nice, secure, production worthy lamp setup and running quickly. This is one of the main reasons I love debian so much. In this I assume that you have a bare newly rented server without any prior installations and I cover a few of my common practices that make my life as a sysadmin a little bit easier. We will forget for now that some of their policy decisions seem to be motivated by to much coffee and estrogen.

An Australian retailer is defying Apple and the courts by continuing to sell Samsung's Galaxy Tab 10.1 to Aussies, despite the temporary injunction.

It's been a year of new developments for open source. 2011 began with open source web content management system Drupal announcing Drupal 7 and the addition of native support for RDFa, a technological building block for the semantic web. And just last week, DotNetNuke said it would use CSS and HTML5 to ensure websites adapt automatically to an array of mobile devices.

OpenStack provides an easy-to-use GUI front end and a command line front end for all major cloud platforms and all major VM formats

Currently the CentOS 6 packages need to be supplemented from other repos in order to install many perl modules for example. Unfortunately, the RpmForge repo is behind so you will need to add the Epel repo as well. If you do this be sure to use yum priorities to help sort it all out.

Fedora 16 GNOME3 is as good as GNOME3 system can be. It is stable, solid and has good reputation. If you like interface of "new wave" desktop environments (GNOME3, Unity), then you should be able to use Fedora without many issues.

Yes, I know: why another webserver tutorial when there are so many good Apache howtos on the Internet? Because this is about what we've been saying for a while: use the right tool for the right job. And while we don't want to badmouth Apache, which is indeed a quality webserver, it offers lots of capabilities that aren't needed on a small scale machine. That's like using a Hummer for commuting, when a Smart would do just fine, if not better. So, if you need to quickly be online and offer services with a small website, Monkey might be for you.

LXer Feature: 10-Nov-2011

I never knew I needed a tablet the same way I did not know I needed a cell phone. Once that first cell phone landed in my pocket, I never looked back. The transition was purely natural. It increased my productivity by allowing me access to hundreds of previously physically-based things. My phone now scans my receipts (no paper, no saving and stashing), tracks my tasks (no To Do lists floating around), takes photos (no extra camera), and a hundred other backpack-lightening life upgrades.

GNOME 3 has become something of a polarising moment for the popular Linux desktop. In chasing visions of tablets, touchscreens and the mythical "everyday user", the GNOME 3 Shell has left many Linux power users scratching their heads, wondering why the GNOME developers decided to fix a desktop that wasn't broken.
