Due to a server side misconfiguration, outgoing mails were bouncing for sometime. I identified the culprit to be:

/etc/hosts:

::1			localhost localhost.my.domain

After I fixed it, there was more collateral damage. A large number of subscribers were marked as “nomail” (i.e. delivery disabled due to excessive bounces). I didn’t see an easy way of mass enabling the delivery. So I wrote this little script.

Enjoy.

My WD passport drive boots from the USB port nearest to the SD card reader. Try booting from any of the other USB ports – things don’t work. Totally undocumented weirdness. HP folks: would you care documenting this next time please?

Just got it installed on my external USB disk. The installer totally rocks. Things I noticed (especially relative to Fedora 11):

• Timezone picker widget is 100 times more usable
• Does a much better job of detecting other OSes

Looks like the larger installed base of Ubuntu is clearly showing. The strength of Fedora is really that a lot of the Linux development still happens there. It’s just that Ubuntu looks a lot more polished at this point in time.

Downloaded a copy today. The install instructions ask you to dd the iso into a USB stick. That’s not so nice – for people with other data (eg: images, music) on the flash drive. I tried using unetbootin – but didn’t work out of the box. Here’s the trick:

1. Assumes you’ve already run unetbootin once on your USB key. Backup syslinux.cfg if necessary.
2. mount the image and then extract vmlinuz0, initrd0.img and splash.jpg onto the USB stick.
3. Copy isolinux.cfg as syslinux.cfg
4. Edit root=/dev/sdb1 rootfstype=vfat in syslinux.cfg. Replace sdb1 with the device name or label for your setup.

Reboot.

Overall impressions: Looks like a slick interface. As an end user I wish projects like maemo, moblin and android cooperated and produced one polished product.

Getting X right with various chipsets continues to be a challenge to open source challengers to the desktop crown. Installed Ubuntu Intrepid Ibex this morning. Everything goes fine – except for graphics.

The bug seems to have been reported for both Fedora and Ubuntu

The workaround that worked for me:

Section "Device"
Identifier "Configured Video Device"
Option "DRI" "false"
EndSection


I had to use the following in my /etc/X11/xorg.conf to get acceptable performance on a old PC with Ubuntu 8.04 installed.

Section "Device"
	Identifier	"Configured Video Device"
	Option          "AccelMethod" "EXA"
	Option          "AGPMode" "4"
	Option          "ColorTiling" "1"
EndSection

There are several examples like that, that we have to address without worrying about the fundamentalism in some of the open-source community,” he said. “One can be an open-source advocate without being an open-source fundamentalist.

Not many people know the origin of the term “gentoo” or how it is related to India. I was messing around with a linux distro called Gentoo Linux and bumped into a description on wikipedia.

There are many descriptions of the word on the internet (such as the term used by the portuguese to describe Telugu speaking people). But this one coming from what looks like a Hindu nationalist website, looks interesting:

An Arab geographical term “Hindu” was mutated by the British into a fictional religious category “Gentoo”. The tribals — the Kols, the Bhils, the Hos, the Nagas, the Mizos — had all disappeared. The Sikhs, the Buddhists, the Jains, the Zorastrians had all disappeared. The British had fought against and displaced the Muslim rulers — so they recognized the Muslim category — the rest of Indian diversity was lumped into one unreliable category of “Gentoo”, and a fiction of a “Code of Gentoo laws” was created in a land in which religion arose from Dharma, not texts and written laws.

Although the name Gentoo Linux comes from the penguins , its connection to India is fascinating. I suspect many Indians wouldn’t be flattered by the above description.

Hmm, the above wikipedia page blames the French for the derogatory term first used to describe Egyptians.

While Mocking MIT’s $100 laptop project, Bill Gates said

Hardware is a small part of the cost” of providing computing capabilities, he said, adding that the big costs come from network connectivity, applications and support.

Someone at MS seems to be feeding him misinformation about BRIC. Here are some stats from India:

Whether the commodity OS is a Linux/BSD or pirated Windows depends on the seller and the buyer.

Not many people seem to know about the FreeBSD hg repo that is tracking cvs. It seems to have all 13 years of history in it.

And of course, there is the linux kernel repo hosted on kernel.org.
