Linux Kernel 2.6.29 installation guide for Ubuntu and Debian Linux

Aside

The Ubuntu kernel guys have released an “official” build of the 2.6.29 Linux Kernel which came out tonight. The .deb files work for both Ubuntu and Debian!  (and outdated, stable and test releases like Ubuntu 9.04 jaunty jackalope.

The included kernel files have been compiled using the generic ubuntu configuration but lack ubuntu specific drivers.  Note: nVIDIA ForceWare drivers are automaticly installed using DKMS (which is included in Ubuntu 8.10)

The files can be found at http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/

Installation Guide

  1. Download http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/linux-headers-2.6.29-020629_2.6.29-020629_all.deb
  2. Download your kernel headers package;
    I386:  http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/linux-headers-2.6.29-020629-generic_2.6.29-020629_i386.deb
    AMD64: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/linux-headers-2.6.29-020629-generic_2.6.29-020629_amd64.deb
  3. Download your kernel compile;
    I386:  http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/linux-image-2.6.29-020629-generic_2.6.29-020629_i386.deb
    AMD64: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/linux-image-2.6.29-020629-generic_2.6.29-020629_amd64.deb
  4. Install the files in the same order as mentions above! (doing step 1 and 2 the other way around isn`t possible!)
    For lazy guys console freaks; dpkg -i *.deb
    (Notice: the console have to be in the same directory as the downloads and no other .deb packages should be there – else they also get installed)
  5. Reboot and select the kernel from the bootloader menu

Howling Noise

Aside

 I`ve finally found a solution to the howling noise my pc was making.
Audio demo: howling-noise (60dB gain from the original!)

Symptoms:

  • Both soundcards on both speakersets had the same “noise” (meaning it couldn`t be the soundcard, cabling system or speakers!)
  • Shutting down my sequencer stopped the noise
  • The noise was periodic
  • The soundcard`s controlpanel VUmeters lighten up so the problem was “in the box”.

The problem seemed to be in the box, next step was locating the problem.
It could be:

  1. Routing scheme problem
  2. Instrument
  3. Effect

It seemed to be an instrument with effects on it. The effects on the channel seemed to cause the problem.

Microformats implementation

Aside

apress-micoformatsI`ve recieved “Microformats: Empowering Your Markup for Web 2.0” (ISBN 978-1-59059-814-6) a few days ago.
I`ve been busy implanting MicroFormats to this website.
It`s now possible to import hCard data whenever you`re trying to place a comment. The website is also MicroID enabled. I`ve also added APML support to the website.

In addition to the new features I`ve also fixed a caching bug (which was my fault actually).

And ofcourse the forum has been working for the last 2 weeks atleast.

I`m currently exploring DandyID to replace a bit of the current menu to a half-automatic identity manager.

Season Greetings

Aside

While Santa is loading his rendeer with gifts, I`m working a few extra hours the next couple of weeks.

I wish all readers a merry christmas and a happy new year!

I will replace the snow on the site with fireworks just a couple of days before new years day.

I totally forgot to mention that Dreammaster Records has a x-mas theme since a few days.

5 reasons to choose OpenSolaris for your webserver

Aside

OpenSolaris 2008.05 is the first official binary release. It was also called project Indiana.
The most important features are Dtrace monitoring, ZFS filesystem, VirtualBox for virtualization and the LiveCD function.
OpenSolaris uses the Gnome GUI which is the same GUI as Ubuntu and other Linux Distro`s.

The five reasons why i will choose OpenSolaris 2008.05 instead of Linux for my next webserver;

1. The price (free)

It`s free and its Open Source. Using the software on multiple servers doesn`t cost you a penny more!

It`s possible to order a free (bootable) DVD with OpenSolaris 2008.05 on it (click here to order the dvd)

2. Stability

Because OpenSolaris is based on Solaris (which is based on Unix System V, like IBM AIX and HP-UX) it`s reliable.
Solaris is the number 2 most reliable OS with uptimes over 99,98% (if you don`t believe me better check out these links; http://blog.linuxoss.com/2007/05/linux-versus-windows-os-impact-on-uptime-and-speed/ )

Sun contributes to a range of open source projects, including their productrange MySQLTM, NetBeansTM, GlassFishTM, OpenOffice.orgTM, OpenJDKTM, java.net, and many others which you might have heard of.

3. Performance

With the monitoring and analysis tool Dtrace (which stands for Dynamic Tracing)
DTrace provides the observability to accelerate application development and optimization of Apache/MySQL/PHP (AMP) and MySQL/Apache/Ruby/Solaris (MARS) stacks which run on the system.

4. Solaris ZFS Filesystem

ZFS stands for Zettabyte file system, which is Sun`s way of datastorage. Ever wanted a filesystem which doesn`t need maintenance or is 128 bit?

Unlike other filesystems it has been designed with the idea in mind that all disks will eventually fail. It has excellent data-loss detection mechanisms and can even detect silent data corruption (see the ZFS end-to-end data integrity post).

The thing that I like about ZFS the most is the freedom when assigning resources to different mount points. With other file systems I was always limited about how I structured my partition table (e.g. space for /usr, space for /home etc.). With ZFS there are so called pools and all the mount points share the same pool, so it is much harder to get out of space. (Quote from The Observatory, Sun Blog)

5. Virtualization

OpenSolaris is also Xen-hypervisor enabled as both a virtualization domain and guest.
As a separate free download, Sun also provides VirtualBox as host-based virtualization for Linux and Windows compatibility. I recommend you to try VirtualBox (version 1.6.2) if your going to experiment with virtualization since its totally free.

And if your going to switch to OpenSolaris I recommend checking out these sites;
