Linus about "const pointers"

Posted by coldtobi | 28 Jan, 2008, 21:00

The concept of the C-modifier "const" is often misunderstood. On a recent question one person asked why there was a "const" parameter to the kfree syscall.

My Thecus N2100 arrived

Posted by coldtobi | 26 Jan, 2008, 20:22

My new toy finally arrived: My Thecus N2100, the winner of my "which-NAS-fits-me-best"-competion.

Here's a brief summary of its key features, as already told in the above article:

  • not sealed. (Have-to-open for installation.)
  • two options for "own linux on the box": Reflash with debian kernel, or run debian in an chroot.
  • comes with128 MB DDR-RAM; expandable up to 512MB with standard DDR memory module.
  • 2 Ethernet interfaces, both Gbit
  • 3 USB2.0, additionally 1 internal. (that hidden by the case. Needs mod too utilize.)
  • Debian supported, can be installed with sotck debian installer.
  • Internal mini-PCI slot. Can be used for WLAN, if the two GBits are not enough.
  • Intel XScale 80219 CPU @ 600 MHz. FAAAASST!!!

Together with two Samsung Spinpoint F1, HDJ753 -- with a combined storage of 1.5 Terrabytes -- and and upgraded with 512MB DDR Bar, this is a very good hacking opportunity. As my plans include hacking for it, I created a dedicated category for that topic.

Have fun!

(First pictures I made are currently on my camera and will be added soon....)

Do not buy from spammers.

Posted by coldtobi | 24 Jan, 2008, 10:10

A mail -- slipped through spammassassin -- advertised for a site, "where you can write your friends a cool greeting" (well, the site is German, accept appologies for the poor translation.)  The service used seveal registered domains -- probably tocountermeasure anti-spam -- but the all eventually redirect to the one: No, I won't link to them. Do a google search for "Für einen coolen Gruss gibt es einen Grund!".

On the other side, I used that to start an experiment: I "registered" with them using a "non guessable, random" email address. If there is more than the message "to myself", then you this is a prove that they a not cosher.

Install OpenWRT on the La Fonera

Posted by coldtobi | 23 Jan, 2008, 18:50

Some days ago, I patched the La Fonera to support RedBoot over Ethernet. As this is a very good opportunity trying out OpenWRT, I am gonna install OpenWRT on this piece.

La Fonera: A better way to enable RedBoot via Telnet / Ethernet (safely) [HowTo]

Posted by coldtobi | 21 Jan, 2008, 02:11

Booting La Fonera -- Redboot Bootloader

RedBoot is the bootloader used in the La Fonera. As this bootloader can not only operate over RS232, it also can be configured to offer a simple -- but powerful -- dedicated shell over telnet / Ethernet.  This is also true for the La Fonera, but has only one  problem: It has no IP configured, therefore you cannot use it. We'll gonna change that now!

Update: Now, 2014, the original locations of the files are gone. Please see the bottom of the post for an solution.

Ooops -- RSS was not working well

Posted by coldtobi | 15 Jan, 2008, 20:15

Due a configuration error, all the RSSs where inaccessible. However, I wonder that it was undetected till now...

As I upgraded to the latest lifetype last summer, just symlinked the old directory to the new one to keep the old ones working. However, now I figured out, that this lead to a "Internal Server Error", because there was one slash to much in the path.  Well, now its working again...

Internal Server Error

File "/srv/www//webXXX/html/lifetype-XXX/rss.php" is not in document root of Vhost "/srv/www/webXXX/html"

suPHP 0.6.2

Maybe just a bug in phpSU, as ASFAIK "//" should be fine, at least in a shell, it works.

Updated Navit [Updated debian files]

Posted by coldtobi | 10 Jan, 2008, 23:17

Navit has been updated upstream. Unfortunately this time it's harder to package.the "0.03". But I'm working on it!

Well, it was a stupd error, that caused the build failure. However, I solved it, and now my navit packages are updated.

Please not, that I did not package the latest stable, but the CVS version from Friday, January 11. But this is more an advantage, as since the release of the latest stable navigation software, much has been done and some interesting features had been addes.
