OLPC received well in a remote Peru village of Arahuay


The OLPC has started deployment to schools in some countries.

The way the students interact with it, learn how to use it, and interact to each other is already amazing. There are stories of school drop outs coming back to school for the sake of the laptop, aggressive kids who become experts in the OLPC, and help others out using it, and more.



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.
