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

UMID M1 – design meets function
Nov 5th
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.

Foldable keyboard for your UMPC – an update
Nov 5th
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??
