I’ve got several Saitec flightsim items, and building some additions myself.
For example i’ve got:
But i really wanted the feeling of starting the engine with a knob.
So i build one using alumium scraps and a arduino.
It doesn’t look much, but it all be behind a metal sheet anyway.
Really pleased with the spring reset and multiple settings.
I’ve a lot of bagpipe writer music files, many are the same tune but a little different.
find -type f | egrep -i "bww$|bmw$" | wc -l 34565
Most contain information about composers, complete title, arrangements and information about harmony and seconds/thirds/whatever.
So I made a PHP search script and a BASH indexer.
(This is NOT a safe script to use servers with internet access)
PHP
Strict Search: <form method="post" action="?"><input type="Text" name="words" size=40 value=""><input type="Submit" name="submit" value="search"></form>
Fuzzy Search: <form method="post" action="?"><input type="Text" name="words2" size=40 value=""><input type="Submit" name="submit" value="search">Fuzzy-ness<input type="Text" name="words2key" size=1 value="3"></form>
Parsons Search: <form method="post" action="?"><input type="Text" name="words3" size=40 value=""><input type="Submit" name="submit" value="search">Fuzzy-ness<input type="Text" name="words2key" size=1 value="3"></form>

Just place all files in a directory on a php enabled webserver.
The bash script is being run daily.
(parsons bash script is called from this main script)
These will generate 2 files
One with the filename and all useful text like composers.
And a file with the filename and the parsons code.

xrandr is an official configuration utility to the RandR (Resize and Rotate) X Window System extension. It can be used to set the size, orientation or reflection of the outputs for a screen.
Someone broke my screen at a hackers event. The terminal was really hard to read with the black parts, so i tilted the screen
Quiet friday at work, playing with my little trusty 2530p.
I’m using xmonad, so i don’t need any fancy work laptop.
Another quiet friday at work, working from home, i turned all monitoring displays upside-down, sideways, or rotated them every so much seconds.
While this is a lot of fun to use, i used this to get my monitorsetups exactly the way i wanted, at home or at work.
Different screen sizes, height differences .. no problem.
A fun tool to use is:

Apparenty something wrong with the graphics chip.
The COMX uses the RCA CDP1869 and CDP1870 Video Interface System (VIS), consisting of the CDP1869 address and sound generator and the CDP1870 colour video generator.

Never ask me to reset your password, i you are to stupid to remember or not using a passwordsafe … I WILL give you a new password, and you WILL remember not having to ask me again. 🙂
On this day i drew some example pictures for colleages.
Okay .. now some tips to create uniq passwords for every site in you head.
Type website
dirkjan (press home)
(press right) s
(press right) e
(press right) c
(press right) r
(press right) e
(press right) t
dsierckrjeatn <- your passwordSome websites use ajax and dynamic viewing of larger images.
For a colleage i grabbed a screenshot using below to get him a full sized campsite map.
Firefox example: Open the page, google maps for example.
Press CTRL+SHIFT+M or Responsive Design View from the Developers Tools.
Change the size you want your virtual browser ( and doing so, your screenshot size here 2800 ) And click on the ‘take screenshot from viewport’ icon on the right.
A friend of mine wanted to monitor his UPS using domoticz.
This UPS only had a simple web interface with information.
So we needed to scrape this information and push this into domoticz.
First create a dummy device in domoticz and note its IDX.
Then we can scrape needed information using below script.
#!/bin/bash
#set -x
# Domoticz server
SERVER="127.0.0.1:8080"
# APC Back-UPS HS 500 status URL
UPS="http://IP-OF-UPS/status.cgi"
# The number of the IDX in the list of peripherals
IDX="362"
# Path for temporary file (RAM drive)
TMPFILE="/tmp/apc-hs500-status.txt"
# Get APC Back-UPS HS 500 status and write to temporary file

I got bored and attacked my work laptop with a belt sander!
After getting rid of the embedded logo, i took a can of black chalkpaint.
Created a graph for my Nikon lenses. It shows me what lens i can use at what Aperture / Range.
( https://media.henriaanstoot.nl/websites/lenses/ )
It uses canvas to draw lines and text, but thats only interesting for static stuff. ( https://www.w3schools.com/graphics/canvas_drawing.asp )
My example uses a php script to load information from a csv file. And loops though those entries and draw lens info.
Piece of canvas script to draw 17-70mm lens info.

I’m using a lot of terminals, spawning a new terminal and running ssh, without knowing if i still have a session running.
Lets see:
This was done using something like:
#!/bin/bash count=$(ps -ef | grep xterm | grep -v grep | wc -l) timestamp=$(date +%s) echo "$timestamp,$count" >> /var/local/terminallog
Later i made a script to push this information in Grafana
Now for the SSH part.
I’m jumping from machine to machine using ssh, sometime i loop back to a server i was already connected to .. this helps me to keep track
in ssh_config add SendEnv SSHTRAIL in sshd_config add AcceptEnv SSHTRAIL in /etc/profile export SSHTRAIL=$SSHTRAIL:$HOSTNAME restart sshd when you do this on all your machines you can get a trail of ssh using: echo $SSHTRAIL workstation:server1:server66:server1 I could change the prompt when a loop is detected echo $SSHTRAIL | sed -e 's/:/\n/g' | sort | uniq -c | grep -v 1 | ... | echo "WARNING: loop in ssh"
