Articles on Linux, the open source operating system



A Toronto company put out a job on for Flash developers. The candidate should know Lynux though. What exactly is that?

If everyone pronounced Linux the way Linus does (Lee-nooks), rather than the Anglicized (Lie-nooks) this would not have happened.

Bell Canada and Rogers laptop connection cards provide internet access anywhere (Linux?)


Two wireless providers in Canada started offering laptop access via PC cards.

Bell Canada has introduced laptop cards that provide internet connectivity anywhere in coverage areas. The ads tout the fact that they can be used in a cab or on a train.

These cards use the mobile phone frequencies and data infrastructure (EVDO).

The monthly unlimited plan is $75 which is reasonable.

Ubuntu Edgy 6.10 to Feisty 7.04 upgrade: sound and video issues


Since late November 2006, I had Ubuntu Edgy 6.10 running on my Toshiba Satellite A100-TA6. I wrote a full report on that here.

So, I decided to take the plunge and upgrade to Feisty 7.04, and so the adventure begins.

Intel High Definition Audio (HDA) Sound Problems

My laptop has an Intel HDA sound card.

Ubuntu Linux backup of a laptop using a USB enclosure and the dump utility


Earlier, I wrote about how to use a USB 2.0 hard disk drive enclosure for backup.

In this article, I explain how to use that hard disk using the dump utility.

The dump utility

The dump utility is one of the oldest commands for backup on UNIX system, but not one that is widely used in home and small business Linux systems.

Kubuntu 6.10 Edgy Eft on a Toshiba Laptop Satellite A100 TA6


Finally, after buying and returning two HP laptops, including the HP DV6120, I settled on one that works with Linux. It is the Toshiba Satellite A100 TA6. The product ID is PSAA8C-TA602C.

The hardware configuration is as follows:

  • Intel Centrino Duo T2250 Processor 1.73GHz Processor Speed
  • 15.4" Wide XGA TFT with Trubrite Display
  • 120GB SATA Hard Drive (5400RPM)
  • 1GB DDR2 memory
  • Intel 950 GMA graphics adapter (128 MB shared memory)
  • Intel 3945ABG wireless LAN adapter
  • Realtek 861 audio on Intel High Definition Audio (HDA)
  • DVD Super-Multi Drive +/- Double Layer
  • 10/100 Integrated Ethernet LAN on the back, left side
  • 4 USB ports (two on the right side, and two on the back right)
  • Modem RJ11 port (right hand side)
  • External Microphone Port, Headphone Port
  • S-Video Out (left side)
  • Monitor connection (left side)
  • Firewire (left side)
  • 2 PCMCIA slots (one Cardbus Type II, and one Expresscard)
  • xD/SD/MM/Memory stick card reader (does not work in Linux)
  • 2.8 kg

The laptop cost $1100 at Staples, with $170 for 3 year extended warranty. They matched the price from Best Buy 10 days after I bought it, and that made it $1040.

Setting up a hard disk USB 2.0 enclosure for backup under Linux


For years, I have been using an IDE Travan tape for backup. I detailed the advantages of removable media like tape and how to use it under Linux in another article.

However, the choice of tape drives and tape cartridges for a home office environemnt are rather limited. The media is expensive, and the drives are also expensive.

My Seagate IDE Travan drive is capable of backing up 10GB, and 20GB with compression. This was satisfactory for years, until I got a 4 megapixel camera, and disk usage started to go up. I had to split the backup into two tapes, one for the pictures directory, and another for everything else.

Christian Linux? Fact and Humor


Ubuntu is a very popular Linux distribution. There are many variants, including Kubuntu (Ubuntu with a KDE desktop), Edubuntu (education oriented Ubuntu), ...etc.Now there is a new edition: Christian Ubuntu. No, it is not a joke. It is real. It includes the Bible, as well as web parental control software. Here is the announcement on the Ubuntu Forums.Of course, something like that would always invoke jokes, such as this blog called Ubuntu Christian Edition Facts. It clearly says that it is a joke.

AMD 64 And VIA VT8251On Linux


I needed to update by development server, which is also a home network server, which has Samba, NFS, autofs, NIS as well as the usual LAMP stack, and CVS, subversion, and other tools.

The move was to be  synchronized with my moving from Mandriva to Ubuntu server as well.

Pentium 4 with ASUS P4S8X-MX

Initially, I bought a nice used Pentium 4 2.4 GHz, but it it was unstable and kept rebooting under load. Later, I found out that  the  CPU was defective  and  I am waiting for Intel to send me a replacement. The machine is also based on ASUS P4S8X-MX, which has no lm-sensors support, so CPU and motherboard temperatures and fan speed cannot be monitored on Linux.
