BCS Computer Show – Day 1

Location: 1st floor, Bashani Novo Theater
Time: 13:00 BDT (+6 GMT)
State of mind: Annoying

When all the stalls and pavilions were selling or exhibiting their products, we were sitting idle on the floor of our empty pavilion. No chair to sit, no desk to keep our tech gadgets, and no electrical outlets to recharge ours laptops or the cell phones. HP’s pavilion was right in front of ours, and all we could do was to stare at two of their hot looking sales girls. Staring at the Samsung’s salesgirls was an option too, as two out of three girls were desperately trying to show their cleavage and their bra’s strap. Cream bra goes well with blue saari, I understood.

We kept on poking the BCS officials, and after one and half hour, our desks and the tables arrived. After waiting for another two more hours, the computers arrived. We didn’t had any other decoration piece on the stall, except for the hand drawn Tux replica that Shipar sent.

We started installing Edubuntu on the 700 MHz Toshiba computers, and it a took a long time to do so. Kubuntu refused to accept mouse clicks, and system continuously displayed busy error.

Zia bhai and his friend, Rafiq bhai, Muhib bhai, Farhan, and Rony helped enormously, and I thank them all for helping out.

Search and Destroy Command

Here’s a handy command that I use to delete unwanted files from my office file server:

find . -iname “filename.ext” -exec rm -fv {} \;

-> . means start with current directory
-> -iname means match the file mask in a case sensitive manner
-> “filename.ext” is the desired file name
-> -exec means run this command when a match is found
-> rm -fv command deletes the file verbosely, without asking
-> {} will be replaced with the name of the file found
-> \; is the command terminator

Change the “filename.ext” part of the command to suit your requirements. For me, it’s “*.exe”, “*.mp3”, and “thumbs.db”. Leave the quotes as it is.

Linux Workshop at North South University

A day-long workshop titled “Migrating to Linux: Introduction to Open Source Tools” was held at North South University today. It was jointly organized by Bangkadesh Linux Users Alliance and North South University Computer Club. The speakers were BLUA members Toby Phillipe, Mir Mahbub Alamgir, Ahmed Rafiq-ul-Islam, Mohammad Salman, and me.

Clock-wise: Russell John, Ahmed Rafiq-ul-Islam, Toby Phillippe, Mir Mahbub Alamgir, and Mohammad Salman. At Boomers, Banani.

The workshop was divided into two sessions. The first session started at 11:30, when I started off by giving introductory lectures on Linux and Open Source software. I did a lot of Microsoft-bashing as well, which was my favourite part. The next presentation was Mr. Mahbub Alamgir’s, who talked about Ubuntu and Kubuntu. He demonstrated a Kubuntu Live CD and guided through the installation process. The lunch break was announced 13:30, and all of us had our lunch at Boomers. The second session started at 14:15. Mr. Alamgir continued his presentation and showed the basic desktop usage. Toby Phillippe, our “bideshi” member was the next presenter. Toby used an OOo Impress presentation and gave a lot of helpful tips to the participants on migrating to Linux from Windows. He talked about the Open Source alternatives of Windows programs, which was appreciated by the participants. His presentation was very professional, and I’m sure that he has a lot of public speaking experience. Ahmed Rafiq-ul-Islam’s presentation was next, who talked about the command line interface and it’s necessities. He taught the basic shell commands that are needed for everyday system administration. Since the participant were new to Linux, they had a little difficulty understanding, but I’m sure all of them enjoyed his presentation. Mohammad Salman was supposed to talk about server setup and administration, but we had to cancel his presentation due to lack of time. We took a quick decision on organising another workshop sometime soon where he’ll show Apache, BIND, mySQL, and sendmail installation and workaround. Overall, the workshop was a success. It had strengthened our ties with NSUCC, who’s support was invaluable. My personal thanks goes to Saumen, who coordinated the event from their side. Thanks to NSUCC president Zia bhai and all the the volunteers who helped enormously. Check out http://gallery.linux.org.bd/thumbnails.php?album=24 for photos of the event.

Unstable Google Earth 4 Beta

We apologize for the inconvenience, but Google Earth has crashed. This is a bug in the program, and should never happen under normal circumstances.

It was a great to see the native port of Google Earth for Linux, which was released 2 weeks ago. I downloaded it last week, but installed it today on my Mandriva box. I ran it, but it crashed.

I retried, but it kept on dying at random intervals. It lasted from 30 seconds to 15 minutes, while showing me the sneak peak of it’s capabilities. I zoomed on Buriganga river and saw some ships. The national stadium at Gulistan looked remarkable too.

I’m sure that the random crashes has something to do with my X server configuration, but right now I’m feeling too lazy to search for a fix. Google demanded that it works under Fedora 5 and Ubuntu 5.10, but I didn’t bother to check. I’ll patiently wait till the stable version of Google Earth 4 is out!

Kernel 2.6.17 Released

I just patched my kernel to version 2.6.17, which was released this morning and codenamed “Crazed Snow-Weasel”. Not much pain while patching.
