While studying Iaido, i needed a flashcard study thingy.
So I made this:
So I could guess and practice the names of the moves.

New shirts for our group “Prutsers”
Design made with Inkscape
Joke about this: Someone’s granny said: “Indeed prutsers .. 3 is far to hot for those shirts”
Prutser .. as used many times on this site.
Definitions of botcher. someone who makes mistakes because of incompetence. synonyms: blunderer, bumbler, bungler, butcher, fumbler, sad sack, stumbler. type of: incompetent, incompetent person.
Used in our context: Not serious about the things we create, fast fun and easy .. then we take it apart and make something else.
Using Graphviz and dot language to plot friends and family
I’ve been using the dotty language for many things, this is a who is who displayer.
iptables rules displayer, open ports, gluster brinks/nodes. netstat ports.,
Wil post more about this later
installing
apt-get install graphviz
View it on a website using mojozoom javascipt

Onkyo web control hack
Back in 2009 i’ve posted my web controller for Onkyo in a forum.
Several people build on that source and made android/iphones app using this as example.
It uses pfsockopen with raw packets in php.
Spend a lot of work reverse engineering the tcp headers to be send.
Another fun trick was re-using a trick i’ve used for my ipcam controller and dartabase. (Dart game application)
Below a PDF with first page of forum
I’ve made a alteration in my logitechmediaserver (squeezebox server) which embedded a onkyo volume control part in the gui.
Part of code

}

// write to Receiver
$fp = pfsockopen($receiveripnumber, $receiverlistenport, $errno, $errstr, 30);
//get command from post form
$command=$_POST['cmd'];
//get volume if cmd is numeric
if(is_numeric($command))
{
if ($command > $volumemax) { $command=$volumemax; }
echo $command;
$vol=str_pad(dechex($command), 2, '0', STR_PAD_LEFT);
$command="!1MVL$vol";
}
// Calculate header and datapacket lengths
$length=strlen($command);

$code=chr($length);

Train information board
Staircase pictures
Maybe you also have a white area to fill, here is a suggestion.
For years we collected picture frames, weird and ugly.
We wanted to have a collection of images in our staircase, to fill the white area.
The images are all something we like, have interest in or are personal.
It needed to be on 3 walls, so here was my first design.
A joke my employer didn’t like
I worked for a highly secure position in a financial place.
We had to use so-called RSA keys.
These keys we needed to get access to the servers.
That morning i came in office and had the following conversation with the manager:
ME: It’s far too easy to lose my RSA key, so I left it at home.
Manager: So how are you getting any work done?
ME: Well … i can get the login codes from here, while opening a browser to a popular social site. Here is my webcam, pointing to my RSA key.
(For everyone to see)
Manager: …. blank stare
ME: Now i can access it from anywhere!
Manager: … buttt
I recorded the key, so it displayed only a few old codes.
(It was a looping animated GIF, which looked like a webcam picture)
When explaining he laughed. A two minute joke, two hours making it ..
Working on the NS train displays
Working to get the Dutch Railways Signs working.
I was working on the backend, but frequently was asked to help working on the boards.
I can’t post any other pictures, because they are revealing to much information
I’ve worked on the boards, backend and a peer2peer VPN solution
Bios password fix
Don’t know bios passwd anymore?
start debug.exe
o = out port 0x0070-0x0071 The CMOS and RTC registers (more info below) # Does not seem related but it works! -o 70 2E -o 71 FF -q OR -o 70 17 -o 71 17 -q
Other fixes i’ve used:
Remove cmos battery .. and short the connections with wire.
This CAN completely reset your Bios settings!

Audio CD index
I’ve got a large Folk Music collection. And i wanted to have an overview of the Audio CD’s (mp3/flac) i’ve got from every Band or Artist.
So I made some PHP scripts and a scraping tool. To get a nice overview.
A part of it looks like this:
Most is auto-generated:
The scraper part needs eyed3 (made at a later date)
