Today I have managed to find a bargain, and have ordered 4 x 1GB compact flash cards to run the nodes. (£3.96) I’m just having to negotiate postage at the moment … as £4 per card is a bit excessive!

So provided I can get combined postage current project cost is at £7.96 … Now I need to find some pico / mini itx bargains.

After all the problems I had with Cryp-TAP-2 (here) I’m going strait for the COMBOFIX option! I’ll update with how I get on.

UPDATE: Everything looks good so far, booted into safe mode, and ran combofix, the system is now rebooting normally, now waiting on the log report.

UPDATE2: Combofix did the job YET again! getting a popup or too still about the system restore volume, from the look of the report this little bugger hooks itself into system processes (explorer.exe svchost.exe)

So I have a concept for a 24 node cluster, I want to build to run folding@home and other cancer research projects

The spec is to make it as “green” as possible, the lower the watts/ghz the better, whilst still maintinaing performance.

The downside is the pricing of pico-ITX at the moment, I’m getting quotes for about £200 / node … and that’s without ram, or storage …

What I need is the following.

pico-ITX form factor motherboard with ~1ghz CPU, in quantities of 5 or more

So please leave a comment or use the contact me form if you think you can help, or have any information on suppliers.

Now this one was annoying!

Whilst adding imap support to a php 5.2.2 installation running from a red hat linux 4 distro, I kept getting the same error, when running my custom config script.

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Very strange as the files were there!

[root@dev01 ~]# ldconfig -p |grep ltdl
libltdl.so.3 (libc6) => /usr/lib/libltdl.so.3
libguile-ltdl.so.1 (libc6) => /usr/lib/libguile-ltdl.so.1

So guess what the problem was … PHP’s make script.

Note the “/usr/lib/libltdl.so.3″ this as it would turn out was a symlink to “/usr/lib/libltdl.so.3.1.0″

So just by adding out own symlink without the version number “ln -s /usr/lib/libltdl.so.3.1.0 /usr/lib/libltdl.so” voila the compile runs perfectly!

Another obscure bug *sigh*, ah well at least I can play with the imap extentions now

I was reminded today on MSN that I had in fact written (albeit a long time ago) a class for querying the A2S protocol using PHP sockets.

So I have decided to release the source code for this under the MIT licence.

Bear in mind this was written when the Source SDK was leaked, so it is for PHP 4 (Which reaches “end of life” 08/08/2008 ). And I havent re-tested wheter it works in a LONG long long … etc time.

However With the exception of the addition of RCON functionality (which should of been put in originally Valve!), the A2S protocol has not changed

Anyway check the attached files, the licence is included at the top of the file.

Digg this

As the old adage goes, any security measure is pretty pointless if the attacker has physical access to the machine.

But surely disk encryption should at least slow this down … right?

Well apparently not, as when booted systems like Bitlocker and Filevault store the key in ram, all the attacker need do, is cool the ram stick with an inverted air duster can, take out the DIMM and place it into another machine where the key can be read from.

Scary stuff, there’s even some information as to what data still remains in the RAM once the machine is powered off …
