New article at Linux.com by me: Managing Services on Linux with systemd . You’ve read all about systemd, the new Linux init daemon. You know what it does, and why. Now it’s time to dig in and learn how to make it sit up and beg — or at least start, stop, and get information on services.
Starting and Stopping Services
My earlier piece, “Here We Go Again, Another Linux Init: Intro to systemd” discusses the concepts behind systemd and what it is supposed to do. Now it’s time to learn how to use it to control services on our systems. systemd is backwards-compatible with sysvinit and Upstart, so you can try it out by installing it on any Linux that uses sysvinit or Upstart without a lot of extra work. Arch Linux, Debian, and OpenSUSE all include systemd in their software repositories.
New article by me at Olex Wazi: Nmap Network Probing Cheatsheet– Nmap is a powerful utility for scanning your network and discovering all kinds of information about who is on it and what they’re doing. You can discover used and unused IP addresses, hostnames, services, and operating systems, and their versions – information that can help you monitor who is on your network, and lead you to unsafe or unauthorized servers.

Crash course: How to make a website with Drupal
Drupal is an amazing content management system (CMS) that can build pretty much any Web site you want it to — if you can figure out how. Follow along as I remake my personal Web site, bratgrrl.com, using Drupal.

More of my favorites on IT World: The 10 best open source apps you never heard of
“There are thousands of excellent open source programs to choose from. Here are 10 of my favorites that rarely get breathless buzz or make top 10 lists, presented in no particular order, rhyme, or reason.
“Ardour Digital Audio Workstation (DAW)
“The Ardour digital audio workstation is a first-rate multi-channel audio recorder, editor, and mixer. It runs on Mac OS X and Linux, which are both superior audio production platforms. It supports a wide range of audio file formats, has non-destructive editing with unlimited undo, and unlimited tracks and buses. (Limited only by your computer when it reaches its limits and keels over.)
“Ardour organizes a recording session by buses. An audio bus, whether hardware or software, is a grouping of tracks. Then any edits are applied to all tracks on the bus, as though it were a single track. For example you might route all the bassoon tracks to a single bus because you want to get editing the bassoons over with quickly…”
Here is Sam Varghese’s in-depth interview interview with me. Not bad if I say so myself: FOSS advocate who’s free, frank and fearless.
“Journalist, FOSS advocate, feminist – Carla Schroder is all these and more. But more than anything it is her straight talking that marks her out – when she takes a stand on issues she is driven by conviction.
“This means that often she is at the receiving end but it is something that she can more than handle. The good thing about dealing with her is that she never allows her personal and professional worlds to mix – even her worst enemy will be allowed to have his/her say on a site which she edits. This is indeed a rare trait.
“Schroder was recently in the news when her gig with Linux Today, one of the better-known FOSS news aggregation sites, ended in dismissal. Her readers liked what she was doing but the management apparently did not. The terms of her leaving do not permit her to say anything about it.
“But there is a lot more to Schroder than what she did at Linux Today. She has moved on and rejoined LXer where she was an editor before joining Linux Today. She took some time off to speak to iTWire about her present, her past and what she looks forward to…”

The Debian project is pleased to announce the first update of its stable distribution Debian 6.0 (codename “squeeze”). This update mainly adds corrections for security problems to the stable release, along with a few adjustment to serious problems.
Please note that this update does not constitute a new version of Debian 6.0 but only updates some of the packages included. There is no need to throw away 6.0 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.
Those who frequently install updates from security.debian.org won’t have to update many packages and most updates from security.debian.org are included in this update…
