small tools, scripts and command line recipes
View All TagsThis is the short TeamSpeak 3 server update script that I use on the blog server. The script takes one parameter, which is the url of the release archive. It downloads the archive, extracts it and copies the files into the directory of the running server.
I recently removed google analytics and found out about goaccess which just works with log files. So here are a few usefull commands for running goaccess on the command line with apache logs for future me and anybody else.
At the moment I only have limited mobile bandwidth but still like to browse the web and read some articles. The problem with browsing news sites or blogs or basically anything today is the massive bloat that comes along the small information one is actually looking for. As I don't care much about fancy css, js or images i decided to set up a small nodejs server app that loads the html document behind an url, strips all the bloat and only sends the text I want to read.
This post collects the whole history of one project. The desktop server HwInfoTransmitter reads the sensor data of your Windows machine, and the mobile client HwInfoReceiver, later called HwR, shows these sensors on your Android device. The notes below cover June 2014 until May 2018.
Ever tried to render something with openGL on a linux server that has no x11 installed nor has a physical gpu connected? I searched for a long time for a solution that would work almost out of the box and the first solution i could find was actually installing x11, mesa3d and a dummy x-display. Via putty that has x11-forwarding enabled it is possible to run x-applications just fine and even render with openGL thanks to mesa in software mode!
But as soon as you close the ssh connection x11 stops and after that x-applications and openGL won't be able to connect to a display! So after every server restart openGL won't work anymore...
So why do you need a display or x11 if you want to render offscreen?
I made a little tool which allows me to download tiles from bing maps and puts them together.
The next updates will add a proper thread for the stiching process which currently blocks the Ui till it's done. Anyways grab it from github.
These two projects came out of my studies at university. I study media informatics, and the semester projects allowed any object oriented programming language. Neither project became a long running hobby project, so the whole story sits in one post.
