KDE 4.4 in Fedora: new Dasboard configuration

Saturday, February 27th, 2010

As KDE 4.4 has hit the stable update repositories for Fedora a couple of days ago, I updated my parent’s computer. While doing that, I noticed that some options have been moved around, noticeably the ones concerning the Dashboard configuration.

Some months ago, I wrote a post about “Configure the KDE Dashboard to behave like in OSX“; the options to configure this have now been moved to System Settings > Desktop > Workspace. Simply select “Show an Independent Widget Set” in the drop-down box and you are done in KDE 4.4.

Fedora: Configure the KDE Dashboard to behave like in OSX

Sunday, November 1st, 2009

One thing I absolutely loved on my Mac (OSX 10.4 Tiger at the time), was the way the Dashboard behaved. All other implementations of this feature I have seen on Windows Vista/7 and the default KDE 4.3 configuration sucked in comparison. For those of you unfamiliar with the OSX Dashboard concept, let me explain it to you…

EDIT: since KDE 4.4, options have been moved!

After quite a while, Skype has released a new version of their client for Linux (2.1 Beta). It FINALLY supports PulseAudio without having to tweak your whole sound system…It’s supported for Fedora 9+, Ubuntu 8+, Debian Lenny and OpenSUSE 11+.

Get the new version here.

Should yum/PackageKit go the Solaris way?

Saturday, August 22nd, 2009

Recently I got a new job as a sysadmin in a company running Solaris 10 servers. I’m not really used to this OS, so I’ve ordered some books and read a ton of articles about it. As always, it’s quite a challenge to switch from one OS to another; you have to learn its way of doing things, its admin tools, its legacy…

Solaris 10 feels particularly old compared to modern Linux distros  like Fedora or enterprise-class Linux distros like CentOS/RHEL, but there are also a couple of very cool technologies included. This blog post is probably the first of a series dedicated to Linux -> Solaris migrations, and how we can learn things from Solaris to improve Linux.

New 64-Bit Flash plugin from Adobe

Saturday, August 15th, 2009

I didn’t notice it before, but Adobe has released a new version of their 64-Bit Flash plugin for Linux. I quote: “The 64-bit Flash Player 10 alpha refresh for Linux was released on July 30, 2009.”

Grab it on the Adobe Labs page and follow my instructions on this blogpost to install it. these instructions are valid for Fedora 10, 11 and basically any 64-Bit Linux OS.

Banshee + Podcasts + Nokia phone = epic win

Thursday, July 30th, 2009

The last time I tried the Banshee music player it was around Fedora 8/9 and it was very buggy with a lot of crashes. So until now I was using the default Rhythmbox application provided with Fedora 11/Gnome to listen to music and manage my podcasts. To be honest, Rhythmbox was a bit flawed for my use case as it didn’t allow to synchronize my podcasts to my music player (a Nokia 5310 phone); I was using an rsync script for that. Recently, things went downhill…DAAP music sharing worked when it wanted to work and with the latest update, Rhythmbox has bricked all my podcast feeds. Great.

So it was the perfect opportunity to look for another application…it turns out that Banshee is now a really great and mature product (if you don’t mind installing the Mono stack). It supports smart playlists, automatic cover art download, dynamic music library update, videos using the gstreamer back-end, online radios, podcasts AND an automatic synchronization to my Nokia phone! Wooohooo…the only drawback in comparison to Rhythmbox is that it doesn’t act as a DAAP music server.

Natively run Fedora 11 on an Intel Mac

Wednesday, July 22nd, 2009

For various reasons I like the Apple Mac Minis, they are cheap, compact, silent, energy efficient and quite powerful. So sometimes I use them as mini servers for some tasks, like as an rsync backup server. For that, I usually install Fedora on them…these Macs are supported since Fedora 9 or so.

When you want to install Fedora on one of these machines, you have 2 choices:

  • Use Bootcamp to create an OS X/Fedora dual boot system.
  • Install Fedora natively as the only OS.

If you use the second option (which is what I do), you will soon be faced with an annoying problem: the Fedora you just installed via the graphical interface probably won’t boot. Your Mac will display a message saying something like “No boot device found, please insert a bootable media”. Duh.

The problem is that Intel Macs are using EFI instead of a standard BIOS, and the hard drive is pre-formatted with a “gpt” partition table instead of the standard “msdos” partition table. To install a working stand-alone Fedora on such a machine, you have to do ONE thing at the right moment:

  • When you launch the Anaconda installer from the DVD, hit ctrl+alt+F2 to switch to a console.
  • Run “parted” to modify your hard drive structure.
  • In parted, run “mklabel msdos” to switch from gpt to the more standard msdos disk label. This will destroy all your data, so be careful.
  • Switch back to the installer with ctrl+alt+F6.
  • Install Fedora 11 like you do it usually.

That’s it…it can be quite frustrating if you don’t think about it.

Penumbra: 3 great linux games for 5$!

Saturday, July 18th, 2009

Sometimes, it’s happy news day. Today is one of these days. Paradox Interactive has ported 3 great games from the Penumbra series to Linux, they are horror games which received good metacritic scores ranging in the 70. The best thing about these games is that you can buy all 3 of them for only 5$! Go run to their online store, select “Linux” in the little menu and there you go…

They clearly don’t do this for profit, so if you want to support gaming on Linux, go ahead. It works perfectly on Fedora 11 x86-64 after some yum installs :) A more complete description can be read on http://linuxlock.blogspot.com/2009/07/are-you-afraid-you-will-be.html

Steam available on Linux soon?

Friday, June 19th, 2009

There have been rumours about Linux support in Steam for months, but yesterday a friend pointed me at http://store.steampowered.com/app/900804/

If you look at the bottom of the page, you’ll see this:

So, if it’s not a typo, we could have a pretty good surprise soon :)

I/O scheduler and SSD: part 2!

Monday, February 2nd, 2009

After my previous post, I investigated a bit further by changing one single compilation option as a reader suggested. Instead of running “make“, I ran “make -j 3” to run 3 compilation threads in parallel on my Core 2 Duo system.  The results are quite surprising…

First of all, I ran my previous benchmarks again and the results were confirmed with a 17% gain for the NOOP scheduler. Then things got bad :)
