Bug Labs creates open source Lego for software engineers
11-14-2008 12:00 PM
Most of the new breed of open source hardware centers on specific products. Bug Labs is taking a different approach. Instead of developing particular devices, Bug Labs' goal is to provide a Lego-like collection of open source hardware and software that customers can use to build their own devices. According to CEO Peter Semmelhack, the result should be not only a higher degree of innovation, but also a forerunner of the hardware business of the future.
Hi all,
I'm prepared exploring cloud technology to play on both private and public clouds. Please advise which of the following Open Source Cloud software, other than Ubuntu One, will be more powerful on features:-

Hello everyone,
I' m currently working on an open source project and I'm looking for people willing to test the software on various platforms so that we'll be able to publish a compatibility list.
The project is called CorneliOS, it's a webOS and web application framework, and it has been... (0 Replies)
I'm look for some opinion on mathematical software from any engineers out there. What is the open source application that --in your opinion(s) -- best meets the same requirements as Mathematica or Maple?
I'm running FreeBSD & Linux, btw. (3 Replies)
SYSTRAQ(8) [FIXME: manual] SYSTRAQ(8)NAME
systraq - monitors your system and warns you when files change
SYNOPSIS
systraq
DESCRIPTION
systraq is part of the systraq package, a set of scripts that monitors your system for file changes. It is meant to be run by a cronjob,
not directly.
systraq runs various system commands, to inspect the state of the system: what is it doing now?, what has it been doing recently?, are we
running to hardware limitations?. Furthermore, it runs commands to inspect some files in users' homedirectories, as well as some system
files, for frequently seen flaws. All these commands are maintained in little scripts in /etc/systraq/systraq.d. The first two characters
of the script's name are used for the execution-order. The names of executable files in systraq.d/ (or symlinks to such files) must consist
entirely of upper and lower case letters, digits, underscores, and hyphens. Files which not adhere will be silently ignored. The systraq
script supplies some environment variables to the scripts in systraq.d/, these might be helpful when adding your own scripts. Refer to the
(very small) systraq code itself for the details.
We'll elaborate on some of the shipped systraq.d/ scripts.
AA-shellrc checks for unsafe umask setting in shell startup scripts, or unsafe PATH in these scripts.
AA-debsums runs debsums, to check md5sums as stated in packaging files with the sums of the actual files running the system. (NB: debsums
has support for md5 checksums only, most Debian packages ship md5 checksums only. Therefore, we can't use sha256sum. See also the
discussion on proposed release goal: DEBIAN/md5sums for all packages[1] at the Debian release mailinglist in August 2007 as well as Debian
Bug #268658[2] for some considerations on this.)
AA-localdigest runs sha256sum (or the command set in the ST_SUM environment variable) to check message digests as locally maintained in a
file named in the ST_LDIGESTS environment variable. Typically, this is set to /var/lib/systraq/systraq.sums. If this environment variable
is unset, this check is silenty skipped.
Of course, you can add your own scripts. If you name them AA-local, they'll never get overwritten by any version of this software. If you
don't like one of these scripts, you can disable it by removing the symlink, and creating a new symlink with the same name pointing to
/bin/true.
