howTo: Jaunty Jackalope with custom netbook kernel
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.

Gigabyte Q1000C Netbook
about 1 week ago - No comments
Gigabyte Q1000c is another 10-inch netbook revealed by the company at CeBIT this year beside the Gigabyte T1000. Arrive in a smoother curves chassis and a 6-cell 4400mAh battery, Gigabyte Q1000c is a good looking netbook.
Q1000c is powered by a 1.66GHz Atom N450 processor, 1GB of RAM and 160-/250-GB of More >
Teclast X8 – Netbook in China
about 2 weeks ago - No comments
Last time I heard a peep out of Chinese PC maker teclast, the company was showing an NVIDIA ION-equipped netbook at Computex last summer. But it looks like Teclast ain’t a one hit-or-miss wonder. Zol spotted a new 10 inch netbook from the company called the Teclast X8.
The Teclast X8 is rather unremarkable in the More >
HowTo: Measuring hard disk performance with linux and ‘hdparm’
about 4 months ago - No comments
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
UMID M1 – design meets function
about 4 months ago - No comments
The UMID M1 will be available in two variants: the “High” version includes a 16GB SSD and is powered by an Intel Atom clocked to 1.33GHz, while the “Low” version comes with Linux preinstalled and has only 8GB flash storage and its Atom runs a bit slower too at 1.1GHz. Both versions have a 4.8″ touchscreen with a “wide” resolution of 1024 x 600 pixels, 512MB of fast 533MHz DDRII RAM, Bluetooth 2.0, also 802.11b/g wifi and HSDPA (with own SIM card slot), connection to other devices is established with USB2.0, but you can also use the microSD-card reader for synchronizing data with, for example, your smartphone. Also included is a 1.3MP webcam for video telephony via skype or other VoIP-based services, and everything is powered by a 2400mAh Li-ion battery.
HowTo: Add 3G/HSDPA functionality to your eeePC 1000H
about 4 months ago - No comments
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)…
Foldable keyboard for your UMPC – an update
about 4 months ago - No comments
For all those users without free USB ports on their smartphones, PDAs, MIDs and other devices, or those with an aversion against cables in general, there are also bluetooth versions of those full-sized foldable keyboards I mentioned already on this blog few days ago – namely I’d like to make mention here of the “Freedom Universal Keyboard²” (from a company called Freedom Input Ltd) with its own two AAA sized batteries and – most important – bluetooth! The manufacturer claims that due to support for both HID mode (used and recognized by all PCs, most PDAs, UMPCs and smartphones) and SPP mode, a bluetooth serial port emulation protocol utilized by the blackberry family of smartphones for example, this gadget enjoys comaptibility to > 200 different devices. Sure is that every device with bluetooth and either Blackberry OS 4.0 and upwards, symbian OS v9, or windows mobile 5 & 6 ( both PPC and smartphone edition), as well as Windows 2000 and WinXP is supported without need to install any drivers. No mention of linux though, and what about windows CE??
My ongoing eeePC "3G mod" adventure
about 4 months ago - No comments
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” …
Asus selling iMac clone with netbook core
about 4 months ago - No comments
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…
"Viliv S5 Premium Air MID": premium UMPC with GPS?
about 4 months ago - No comments
Now Viliv is jumping on the UMPC train too: since several weeks the long-announced “VILIV S5 MID” is available in several configurations. The “Premium Air” version sports a 16GB SSD, 4.8″ touchscreen LCD with a resolution of 1024×600 pixels, and full 3G/HSDPA functionality – whereas the “normal” versions come equipped with 30 or 60 GByte 1.8″ HDD instead, 800×480 LCD only, and no wireless broadband at all. Both models have the same 24Wh battery, allowing for 5-6 hours of continuous use, and are available with either WinXP, Vista or Linux (unspecified distro) preinstalled, both weigh around 380 grams and have 802.11 b/g wifi, bluetooth 2.0 and external video connectors (for VGA, S-Video and Composite-video cables!), the whole controlled by a “Silverthorne” Intel Atom clocked at 1.33GHz and supported by 1GB RAM.
what have fireflies got to do with BASIC?
about 4 months ago - No comments
During the last days I’ve been quite excited about a certain idea I want to report about here, and which I think is quite an entertaining project. During one of my web journeys I recently happened to stumble upon this link over at instructables.com and was fascinated: I was looking at a 5×5 LED matrix that initially blinked its LEDs randomly, but somehow “magically” (with the support of 25 light-dependent resistors) synchronized them very slowly, to finally reach a state of absolute synchronicity – and all this with 25 totally independent control circuits, all based on 25 single atTiny13 microprocessors!! The whole thing should be considered as being a model of large swarms of thousands of male fireflies in sout-eastern asia, which are capable of synchronizing their blinking to attract more female fireflies over a greater distance. For more detailed explanations about the background (and how to set up a physical logic model using AtTiny13 chips and C coding) I want to forward you to the instructables link above as well as to this scientific paper explaining the underlying mathematical theory behind this..
