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

HowTo: Add 3G/HSDPA functionality to your eeePC 1000H
Nov 5th
During the last few months, Asus has started selling the “eeePC 1000H GO” with internal 3G/HSDPA card for easy everywhere connectivity. So far so good, but what about all those thousands of customers that already bought an eeePC 1000H before? Are they doomed to use one of those ugly external USB 3G modems – a threat to your eeePCs health if you drop it accidentally and the USB stick destroys the USB port it was sticking in (if not even more)…

My ongoing eeePC "3G mod" adventure
Nov 5th
Since last night, I had the doubtful joy of having to re-solder two pins of my extra miniPCIe socket (I accidentally dropped my eee from ~50cm heigth and afterwards the 3G card wouldn’t work anymore, which was pretty annoying since I need internet access – so I had to re-open the whole apparatus and take apart everything, leading to the lucky discovery of only said two loose pins as a cause for the malfunction), I will take this as an opportunity to give you the gentle reader some more details about the inner workings of how I did this modification (there may exist better ways I must admit, specifically for securing the modem card in place). That being said, you will surely remember that there’s an old and well known (and true!) proverb saying “A picture sometimes tells more than a thousand words” …
