What are *.chm files? A CHM file is a Microsloth Compressed HTML Help file in a proprietary format (how retarded… no, correct that… differently-abled) for online help files.

To view chm files in Ubuntu… one option is to install this gnome-flavoured reader:

sudo aptitude install gnochm

It works!

Mini Linux = Maxi Interesting

Check out the cool little Linux systems starting to appear…

They mention the Geode processor and the System-On-Chip (SOC) that parallels the build of the OpenMoko (which uses a Samsung vs Intel SOC)… Neatly illustrates the power of these upcoming open-source phones as more standalone, fully-functional computers than simply something to yack away with… and the power of linux to scale across the entire food chain from smallest embedded processor to the most powerful supercomputers on earth.

Howto: Raising Skinny Elephants Is Utterly Boring…

…otherwise known as RSEIUB… a magic key combination for restoring a frozen Linux box.

Instead of hitting the [RESET] button and executing a hard reboot (ouch!) of your knackered system… try this (yesss…) alternative:

While holding down the Alt and SysRq (Print Screen) keys… press in sequence…

    - the r key (switches the keyboard from raw mode… the mode used by programs such as X11 and svgalib, to XLATE mode)
    - the s key (attempts to sync all mounted filesystems)
    - the e key (sends the SIGTERM signal to all processes except init)
    - the i key (sends the SIGKILL signal to all processes except init)
    - the u key (attempts to remount all mounted filesystems in read-only mode)
    - the b key (immediately reboots the system… without unmounting partitions or syncing)

I stuck this on a post-it next to my monitor… Now I just have to wait (…and wait.. and wait… it is Linux, after all) for the system to lockup solid…

HOWTO - Getting Started with Arduino

August 24, 2007 – 5:46 am

R. Stern has posted an introduction to the Arduino as a means to jumpstarting efforts in DIY electronics:

I’ve compiled a brief tutorial on getting started with Arduino for the absolute beginner. I’ll cover where to learn, what to buy, and where to go for help. Why should you crafters be interested in Arduino? The Arduino platform, more-so than any other way of incorporating electronics into your projects, is geared towards do-it-yourselfers. It’s open source (both on a hardware and software level), so the community plays a large role in its development and improvement.

I like it! Definitely worth bookmarking…
