HowTo: Measuring hard disk performance with linux and ‘hdparm’
Nov 5th
Measuring sequential disk performance with linux is easy – most distros (like ubuntu) come with a tool called hdparm , that is mainly used for tuning and optimizing hard disk parameters, but luckily it also includes simple benchmark functionality – for example the following command sudo hdparm -t /dev/sda gives me the following output: /dev/hda: Timing buffered disk reads: 176 MB in 3.01 seconds = 58.55 MB/sec Of course you need to substitute /dev/sda with the name of your raw disk device (for example, it might be /dev/hda for non-SATA disks) . Its impossible to get higher transfer rates that that from your disk. Hdparm reads at the very start of the disk for these tests (which is the fastest area of the whole harddisk) and using optimal access pattern

Asus selling iMac clone with netbook core
Nov 5th
I’m sure everyone knows those design-award-winning Apple iMac computers that look like just a flat panel LCD and keyboard standing on your desk, but contain a whole macintosh… Now Asus has realized the advantages of such a design and is selling a computer-inside-an-LCD too. The “Asus eeeTop ET1602″ has about the same specs as the average eeePC 1000H netbook (making guesses about the interior of this device very easy), namely intel Atom N270 clocked to 1.6GHz, 533MHz Frontside Bus, 1GB DDR2 RAM, the rather weak Intel 945G graphics chipset, 160GB SATA-II harddisk (spinning at only 5400rpm), connectivity is provided by 802.11 b/g/n wifi, bluetooth and 1000MBit LAN, the thing has a 1.3MP webcam and built-in stereo microphone – and so far, I could just as well have read the description from the package of my eee1000H instead, without any difference…

howTo: Jaunty Jackalope with custom netbook kernel
Nov 5th
Now it has been over a week since I installed Ubuntu 9.04 “Jaunty Jackalope” on my netbook, and in the meantime I’ve been working on customizing things to my needs. One main tweak consisted of replacing the default “2.6.28-8-generic” kernel with the more appropriate “2.6.28-12-netbook-eeepc” kernel compiled by Adam McDaniel over at array.org , main reason was merely the unpleasant sound of the word “generic” to me, since this “generic” kernel was working quite well – there was no obvious need to replace it. But I still thought it would be nice to have the core of the operating system customized to my hardware.
