Firefox 7

Switched my default browser back to Firefox from Chrome after a few years. With Firefox 7, I don’t feel there is a significant performance delta between the two browsers. Competition was clearly good for consumers in this case.

Dell C521 suspend/resume problems

I have a AMD based desktop from 3-4  years ago that’s working perfectly fine as a Linux desktop box - except that it doesn’t suspend to either ram or disk when I’m not using it.

I’m about to get rid of the PC, unless I can get this fixed somehow. Dell doesn’t have any more BIOS updates and the ubuntu bug has expired and no one seems to care.

Based on the bug trail, it smells like this was working with ubuntu 9.10 + BIOS 1.1.14, but was broken in later kernels. More specifically, the kernel is not able to enter suspend (based on what the LED shows).

Any ideas on how to save my PC and keep the planet green?

libunwind 1.0.1 is here

This was a minor dot release with a bunch of bug fixes for the 1.0 release. Download, enjoy and unwind.

MSFT vs Linux on desktop: still relevant?

10-15 years ago, a post like this would’ve gotten the slashdot crowd all riled up about free software and the “evil empire”.

I’d say it doesn’t matter any more. There is increased competition in the market and don’t know of anybody dual booting. I buy hardware to run Linux and if it allows only crypto signed kernels via UEFI, I’m going to buy something else.

There is another reason why dual booting doesn’t work: the ubuntu installer. My last two attempts at installing ubuntu on a disk with multiple partitions (some Linux, some windows) resulted in data loss. Yeah - I know about the big warnings that the installer shows. But admit it - people are lazy.

In one instance, ubuntu was being installed to an external hard drive and it overwrote the boot sector of my first (windows) hard drive. In the second instance, I told ubuntu 11.04 specifically not to touch an old partition containing /home, but it ignored me and formatted it with ext4 anyway. Hope to be wiser and less lazy next time.
