2019-06-08 I’ve bought myself Uboot the game.
It is one of my favourite board games.
Playing with a cardboard uboot is … okay. But when you have a 3D printer .. do i need to say more?
3D printed version assembled and completed in Jan 2021
Led’s are controlled by a Arduino, Mqtt or a fysical button can be used.
This year i used safe fireworks.
A ledstrip ( about 600 leds ) controlled by an arduino.
Only problem is .. there is no sound, but i managed to fix that 🙂
Started to play in a pipeband myself when i was 14, so it made some impression alright!
(Short version)
Why “rubber ducking’’? While an undergraduate at Imperial College in London, Dave did a lot of work with a research assistant named Greg Pugh, one of the best developers Dave has known. For several months Greg carried around a small yellow rubber duck, which he’d place on his terminal while coding. ( From “The Pragmatic programmer” page 95)
Why rubber ducking?
A very simple but particularly useful technique for finding the cause of a problem is simply to explain it to someone else or even a object. Explain out loud (or in your mind to the duck) what each line of code is doing.
Often while doing so, you will see the problem.
Why Pair Programming?
It is no secret, i like working on a problem alone. Let me do my ‘thing’. But i like the idea of Pair Programming, why?
Changed some code controlling my wacom drawing tablet.
I use this one to draw Art, diagrams and touch up photo’s.
When using multiple screens, i had the problem it would stretch the draw area over multiple screens, streching the ratio. Or it took the work screen to work on.
#!/bin/bash
# using xinput here, check post about two mouses/keyboards on one machine
# Use xrandr to check names check
MONITOR="DP-1"
PAD_NAME='Wacom BambooFun 6x8 Pad pad'
#undo
xsetwacom --set "$PAD_NAME" Button 1 "key +ctrl +z -z -ctrl"
xsetwacom --set "$PAD_NAME" Button 2 "key e"
xsetwacom --set "$PAD_NAME" Button 3 "key h"
ID_STYLUS=`xinput | grep "Pen stylus" | cut -f 2 | cut -c 4-5`
xinput map-to-output $ID_STYLUS $MONITOR
ID_STYLUS_2=`xinput | grep "Pen eraser" | cut -f 2 | cut -c 4-5`
xinput map-to-output $ID_STYLUS_2 $MONITOR
exit 0
Most of the times i use Krita and Gimp.
Switches and access-points
Today i got my RB4011 ! Wooot!
Total tally
To replace .. 4 SLM2008 and a TPLink switch 🙂
I’ll be posting something about connecting an arduino to the serial console using a tcp server later.
Mikrotiks are all you can eat .. And there is a lot of functionality. One of the main features (besides being switches and routers)
Installing extra packages
I’ve got several AccessPoints in my network.
Using a roaming setup, clients can connect to strongest AP.
For our Folkband i’ve setup same.
With the exception of those clients only being able to connect to the Internet, and not the rest of my Network

Bought some large servers with Vincent.
3 ProLiant ML350 G6 with loads of memory and cores.
My 2 nodes are running Ovirt Virtualisation, connected to a qnap iscsi host using 10gbps SFPs. Vincents server is running Proxmox.
Making red wine from the grapes we got from our neighbours.
Funny movie – feet i a bucket of wine
Some books about the subject we own
