Late last year I wrote about the way that modern laptops suck . One of the problems that inspired that post was the excessive heat generated by my Thinkpad T61.
There is a partial solution to this, Fool Control explains how the kernel option pcie_aspm=force can be used on kernels from 2.6.38 onwards to solve […]
I’ve just discovered that the magic database for the file(1) command in Debian/Unstable has no support for Linux Software RAID and that it’s support for BTRFS is lacking (no reporting of space used, number of devices, or the UUID). Below is my first draft of a change to fix these problems. I would appreciate it […]
I was asked for advice on how to start learning Linux. Rather than replying via email I’m writing a blog post for future people who ask such questions and also to get comments from other people which may provide information I missed.
Join a LUG
The best thing to do is to start by joining […]
One thing that happens periodically is that I start a process from an interactive shell, discover that it takes longer than expected, and then want to know how long it took. Basically it’s a retrospective need to have run “time whatever” that I discover after the process has been running for long enough that I […]
Steve Jobs has published an interesting article about Flash . He criticises Flash for being proprietary, this seems a little hypocritical coming from Apple (who’s the only competitor for Microsoft in terms of being the most proprietary computer company) but is in fact correct. Steve advocates HTML5 which is a better technical solution to a […]
Tom Wujec gave an interesting TED talk about training people in team-work and engineering through building the tallest possible structures from 20 pieces of spaghetti, 1 yard of string, and 1 yard of sticky-tape with a time limit of 18 minutes . The project is completed by groups of four people – which is probably […]
I’m running Debian/Unstable on an EeePC 701, I’ve got an SD card for /home etc but the root filesystem is on the internal 4G flash storage which doesn’t have much spare space (I’ve got a full software development environment, GCC, debuggers, etc as well as running KDE4). On some of my systems I’ve started the […]
I want to use the Ext4 filesystem on Xen DomUs. The reason for this is that the problem of fsck times on ext4 (as described in my previous post about Ext4 ) is compounded if you have multiple DomUs running fsck at the same time.
One issue that makes this difficult is the fact that […]
I have just noticed that Red Hat added Ext4 support to RHEL-5 in kernel 2.6.18-110.el5. They also added a new package named e4fsprogs (a break from the e2fsprogs name that has been used for so long). Hopefully they will use a single package for utilities for Ext2/3/4 filesystems in RHEL-6 and not continue this package […]
I’ve been investigating the Ext4 filesystem .
The main factor that is driving me to Ext4 at the moment is fsck times. I have some systems running Ext3 on large filesystems which I need to extend. In most cases Ext3 filesystems have large numbers of Inodes free because the relationship between the number of Inodes […]
