      Kommentare deaktiviert für GNOME Foundation faces software patent lawsuit!

Just today it came to my attention that the GNOME Foundation, a non-profit free software governing foundation, has been approached by what seems to be a patent troll trying to squeeze money out of the non for profit GNOME foundation over a patent, which can only be laughed at. Here is the information that the GNOME foundation gave: https://www.gnome.org/news/2019/09/gnome-foundation-facing-lawsuit-from-rothschild-patent-imaging/ Looking… Read more »

      Kommentare deaktiviert für Kernel update for Marvell Kirkwood TK71 board

After some silence and in preparation for CCC Camp 2019 where I want to use this board as small FTP server I updated the kernel a bit to 3.16.72 (LTS), information here: https://www.warpcomm.org/ and patch here: https://www.warpcomm.org/downloads/tk71/20190815/linux-3.16.72-tk71.patch Maybe some time in the future I’ll forward port the stuff to 4.x or 5.x but this is a bit more effort since… Read more »

      Kommentare deaktiviert für China 40W Laser Cutter / Engraver – You get what you pay for :-)

So, this is the latest addition to my workshop, a _really_ cheap 40W CO2 laser cutter / engraver I got new from eBay for 315EUR – including shipping! For that price you can not expect miracles. Why I did it anyway, being perfectly aware of the possible issues, was that I wanted to play around with laser cutting and especially… Read more »

Teclast F5 – 11.6″ Laptop & Linux

      Keine Kommentare zu Teclast F5 – 11.6″ Laptop & Linux

Last week I was in Hong Kong and shopped a bit for electronics. I love small laptops since I am traveling quite a bit lately and don’t want to carry around too much weight and bulky luggage but still want to be able to do the basic things – some programming, office, web browsing. The current 13″ laptops are already… Read more »

CNC free software – resurrection of legacy mill

Back in the days when PCB making was expensive I started to look at ways to do that on my own. There were basically two: photo lithography and etching or milling. I did not like the idea of having to handle the nasty chemicals for etching so I first decided to get myself a CNC milling machine. Later on I… Read more »

Nachdem die Einspeisevergütung für Photovoltaik (PV) Anlagen enorm gesunken sind, lohnt sich dies eigentlich gar nicht mehr. Der Strompreis für Verbrauchsstrom ist allerdings nach wie vor hoch und sogar noch gestiegen, um die 0,30€ pro kWh brutto. Stromverbrauch zu senken ist eine Methode die Energiekosten zu reduzieren. Wer eine freie Fläche von ein paar Quadratmetern mit Blick in Richtung Süden… Read more »

Intel ME – When the sh*t hits the fan :)

      Kommentare deaktiviert für Intel ME – When the sh*t hits the fan :)

You know, there is a lot of cruel stuff going on these days. Freedom is cut away in many places which in many cases is done by taking away power and control. Having full control over something means to have power and to have the freedom to use this power or not. The Intel ME is a technological implementation of… Read more »
