What’s new in the latest release includes an optimized CFQ scheduler, numerous new wireless drivers, tickless kernel support for the x86-64 and PPC architectures, and much more.

Visiting your favorite sites using Firefox’s bookmarks is far too much of a chore — do you really want to do all that mousing around? Instead, you can use keywords to instantly jump to any site you’ve bookmarked. To do it, after you bookmark a site, right-click on the bookmark, select Properties, type in a short keyword (or even just a letter or two) in the keyword field and click OK. Now, to visit the site, type in the keyword in Firefox’s address bar, and you’ll jump straight to the site.

Here’s a simple way to speed up Web browsing with Firefox — turn on its hidden pipelining feature. When you turn on pipelining, you send several requests to a Web server at a time, rather than sending them one by one, so you can load multiple items on a page concurrently. By default, pipelining is turned off in Firefox, but it’s easy to turn it on:
1. Type about:config into your address bar and hit Enter.
2. In the Filter text box, at the top of the page, type network.http. A list of settings appears, as you can see in the nearby figure.
3. Double-click the “network.http.pipelining” setting, to change it to true.
4. Double-click the “network.http.proxy.pipelining” setting, to change it to true.
5. Double-click the “network.http.pipelining.maxrequests” setting, and in the text box that appears, type in 8 and click OK.
Note that not all Web servers can handle pipelining. If for some reason, you find that your performance suffers with it turned on, reverse the above steps to turn it off.

I had been using Airtel GPRS service to connect internet for a while, in Chennai, and when I traveled to other parts of Tamilnadu.
While I would post the instructions to activate, settings, and connection details later, here is a summary of my experience.
Speed
I get a decent browsing speed when in Chennai. Way better than a dial-up.
However, in other parts of Tamilnadu, the speed is quite low. I guess the reason is EDGE support in Chennai, which is only available in select cities.
Download speed is typically 50 kbps to 100 kbps (Kilobits per second) - transfer 6 to 14 KBps ( KiloBytes per second )

Downloading this document took 18 seconds. It’s hosted on a server in India.
Plans
Airtel postpaid plans ARE costly for GPRS. Like GPRS plans of most
providers, they are data usage based.
There are three plans with postpaid.
- Rs. 399 /month - 100 MB free - Rs. 5 for every MB beyond free usage
- This plan is completely suitable only if you’re going to do occasional mail checking.
- Rs. 599 /month - 1 GB free - Rs. 3 for every MB beyond free usage
- Costly. But worth using for most business purposes
- Rs. 799 /month - 1.5 GB free - Rs. 3 for every MB beyond free usage
- Just a number play. I think Rs. 599 is more worthy, compared to this plan.
I used Mobile Office - Rs. 599 plan
Usage
I got it working with Linux. Here is what I used as of this writing.
- the excellent HP dv6000 series laptop.
- Kubuntu 7.10 (beta)
- kdebluetooth ( and pppd )
- Sony
Ericsson W300i
- Airtel mobile office Rs. 599 plan ( post paid )
When you’re connected to the internet, you would seem “Unreachable” to other people trying to call you. However, if your internet connection is idle, or you’re not transmitting lot of data, you might receive a call.
If you receive a call your internet connection stops. It resumes internet connection once you hang-up.
Summary
If you need internet connectivity when mobile - traveling , to use in the car (assuming someone else is driving) you could very well consider Airtel GPRS. You would need a EDGE compatible cell phone. If you can’t get EDGE support in your city, I don’t think it’s worth using this plan.

ELectronics COrporation of Tamilnadu (ELCOT ) is running a Student Laptop offer. As per ELCOT’s website the offer is providing the laptops at a discounted price for students.
The laptops come preloaded with SUSE Linux. Apart from the default software applications that come with most standard linux distrubutions today, they also have
- NetBeans IDE
- Nero Linux ( though KDE native K3b is also bundled )
- Postgres database
- JasperReports ( an excellent report rendering software based on Java )
Based on the list of bundled softwares I guess it might have KDE graphical desktop environment.
On the hardware side, they ship two brands. Though the brand name is not mentioned, From the specifications and sample picture, one model seems to be HP dvNNNN series. These laptops are quite featureful. I use dv6000 series and most features work out of the box with Kubuntu 7.04.
It is to be noted that ELCOT is pro-open source, and is pushing Linux across the government offices in Tamilnadu. If I remember right, It is also the “purchase” department of IT hardware / software for most government functions in Tamilnadu.
