Setting up webcam exposure under linux
I had some problems with fswebcam to set the automatic exposure. The exact way how to enter certain parameters is not clear from the lacking documentation, but it works fine…
OctoPrint – a new attempt
It was not so simple to set up a Raspberry Pi as a 3D-print server as I had hoped. It started with issues with the WiFi-dongle, continued to a complete…
OctoPi – WiFi issues
Next step in my journey into 3D-printing would be to set up a server to remote-control my 3D-printer. Since two weeks ago I have a spare Raspberry Pi 2 lying…

Merry Christmas & a new laptop
Unbelievable, but the migration to my new laptop and from Windows 7 to Windows 10 is easier than anticipated.
Among other things this is thanks to the following programs:
- Popfile database exporter
- Firefox password exporter
- TheBat Email with built-in Backup/Restore

Is your Firefox getting tired?
I am still convinced that Firefox is a great browser, but lately something went terribly wrong. The browser would take up 1.7 GByte of virtual memory almost immediately after starting, almost independently on the number of open tabs or visited pages.
In order to debug the problem I installed another add-on (after actually reading on the web that add-ons might be the culprit in the first place). The add-on Tab-Data indicates in each open tab the amount of memory used by rendering the contents of the tab.
Well the numbers really did not add up. I usually have around ten open tabs at a single time, and with an average of 2 MByte per tab I really did not come close to 1.7 GByte of virtual memory needed.
The main suspect according to the general agreement on the web is the Ad-blocker. And of course I use an Ad-blocker, because otherwise the web has simply become unusable – blame yourselves with your banners and popups,…
I used to use Adblock Plus but earlier this year I switched to its fork Adblock Edge due to performance and compatibility problems. Yesterday I found the information that Adblock Edge wasn’t recommended anymore and instead it was forked into uBlock Origin “Finally, an efficient blocker. Easy on CPU and memory.”
And so far I must say that this self-confident message appears to be justified. Firefox is now satisfied with about half the amount of virtual memory compared to before the switch and has not crashed yet… (more…)

How could this happen? My website has been hacked in the beginning of this week! As a reaction my provider immediately took it offline, because a script on the server has been used to send out spam… (more…)
Is your Windows computer getting slow?
My laptop very recently got much slower than usual. The harddisk LED was permanently on and it too ages for it to hibernate. I cleaned some garbage from the harddisk…
