Attention with starting vncserver on Ubuntu
At work I have an Ubuntu machine which is always up and running. Therefore I want to connect to it from everywhere. The idea is to have some sort of remote desktop / desktop sharing tool.
NoMachine stopped working for me a couple of years ago. And I admit I never tried the newest version since then.
xrdp does work, but I never got the keyboard mapping right.
Today I tried vncserver, and wondered why the installation description(s) let you create a separate user. Now I know:
I called vncserver with my regular account. Besides not being able to connect from the remote client, I was not able to login to the Ubuntu desktop natively any more! After a long despair time, and with the help of my colleagues (Ctrl-Alt-F1 for console login…), I found the root cause in the logs: My ~/.Xauthority file was owned by root, and my regular user had no rights to change it during login.
My advice to you is: create a separate user if you really feel you should try out vncserver.
So finally I gave X2Go a go, and this worked! The Windows client often crashes when you manage your sessions, but once all is set up it works as desired.
Please be aware: Your remote mileage may vary …
Concat two git repositories in fast-import format
Today I spent a few hours wrapping my head around the documentation of git fast-import, especially the part of restarting an incremental import from the current branch value. The documentation says it should be written as:
from refs/heads/branch^0
or, since the current branch usually is master, as
from refs/heads/master^0
There is also a short answer on nabble. But I could not find an example of how to really edit the input file.
The solution is simple:
Edit the first commit of the second input file without adding a new blank line (the file is named ‘research-git-dump.dat’ in my case).
Before:
commit refs/heads/master mark :1000000000 committer Bubba Gump <bubba.gump@shrimps.com> 1206025332 +0000 data 6 my commit comment M 100644 :2430 MyProject/myfile1 M 100644 :2439 MyProject/myfile2 :
After:
commit refs/heads/master mark :1000000000 committer Bubba Gump <bubba.gump@shrimps.com> 1206025332 +0000 data 6 my commit comment from refs/heads/master^0 M 100644 :2430 MyProject/myfile1 M 100644 :2439 MyProject/myfile2 :
Doing this, the second import went like a charm.
I was able to concat two git repositories created by cvs2git:
$ git init --bare merged.git $ cd merged.git/ $ cat ../custom-git-blob.dat ../custom-git-dump.dat | git fast-import $ cat ../research-git-blob.dat ../research-git-dump.dat | git fast-import $ gitk
… and gitk was happy!
Agile Architecture
The last 3 days I had the pleasure of attending an Architecture Workshop hold by Stefan Toth (@st_toth). We were designing and building a Lego Mindstorm ball path in 3 iterations.
He challenged us with difficult requirements, time restrictions, risk based priorities and much more. The team had great fun and learned a lot about the daily architecture work on the way.
Thanks, Stefan!

Dear Reader,
to be honest, I only have a vague idea why I should and what I could write here.
Sometimes my thoughts move away to a special event, idea or finding from the last day(s). Maybe there is a value in writing it down?
