Blank Keyboard

Da ich rel. häufig zwischen verschiedenen Tastaturlayouts wechsle (US englisch wenn ich auf der Konsole arbeite oder programmiere, Deutsch, wenn ich E-Mails schreibe oder im IRC bin, bulgarisch kyrillisch aus diversen familiären Gründen) habe ich es mir einfach gemacht und mir das Blank Keyboard geholt:

Blank Keyboard pro 100g

| 2 Comments
Der Preis des Blank Keyboards wird auf Amazon auch auf 100g hochgerechnet. Der Sinn erschliesst sich mir nicht, aber dennoch interessant :)

27c3.buetow.org

| 5 Comments
Unter http://27c3.buetow.org sowie ftp://27c3.buetow.org habe ich einen temporären Mirror diverser Vorträge (Video und Audio) des 27. Chaos Communication Congresses angelegt (thx @ fuchur für die Idee). Diesen Mirror werde ich ggf. gegen mitte des Jahres wieder löschen.

Der Mirror ist noch nicht vollständig, da er noch synchronisiert. Nach jeder vollständigen Synchronisation wird derzeit alle 10 Stunden überprüft, ob es etwas Neues gibt. Da der 27c3 bereits vorbei ist ist es noch eine Frage der Zeit bis alle Dateien vorliegen.

Als Grundlage dient folgendes einfache Skript:

#!/usr/local/bin/bash -x

server=$1

cd ~/public_html/27c3

while $(true); do 
        lftp ftp://$server/CCC/27C3/ <<END
mirror -c
END
        sleep 36000
done

Monads in C++

Here is an example on how you could implement Monads in C++. Hrmm... I think I prefer the version of Haskell ;)

Here is a funny way of explaining Monads in Haskell (using Monsters devouring values).

VAX executable binaries on my x86!

I was just looking around a little bit in the .git subdirectory of a local git repository of mine and found out that some files are VAX COFF executables!

pb@earth:~/DataTrap/git/science/.git$ file ./objects/e5/940c1148ae6050cdc20b5978fa7419b2b093eb
./objects/e5/940c1148ae6050cdc20b5978fa7419b2b093eb: VAX COFF executable

;)

VAX is a pretty old computer architecture which runs operating systems like OpenVMS:

Well, .. in real those are just binary blobs where git stores content in. A joke or by accident? Because OpenVMS' file system has integrated version control in its native file system. Its much simpler than git, but... ;)

Using N95 for fixing your MTA

| 1 TrackBack

The last week I was in Vidin, Bulgaria with no internet access and I had to fix my MTA (Postfix) at host.0.buetow.org which serves E-Mail for all my customers at P. B. Labs. Good, that I do not garuantee high availability on my web services (I ve to do a full time job somewhere else too). My first try to find an internet cafe, which was working during christmas time, failed. However, I found with my N95 lots of free wlan hotspots. They refused me logging into my server using ssh (I am using a non standard port for ssh in order to avoid lots of login attempts). Without knowing the price I was using then the GPRS internet access of my german phone provider (yes, I ll have to pay lots of roaming fees). With Putty for N95 and configuring Postfix with Vim and the T9 imput mechanism I managed to fix the poblem. But it took half of an hour. My next mobile phone MUST have a full qwerty keyboard included. This would have made my life lots easier. :)

ATM I am in Sofia, Bulgaria. Here I can use at least an unprotected WLAN hotspot which belongs to one of the neighbors which I don't know in person and it is not blocking any port at all :)

CXG.de DDoS

Today I've had a DDoS attack at cxg.de, our nopaste service. After doing some modifications I hope it's now over. In a few days I'll try to take cxg.de back online.
