The the subtitle of this subforum is a very good idea. Much better then my sticky post suggestion, since the subtitile is much more eye-catching.
A nice win-win solution.

Re: Claim for an Ubuntu sub-forum
I totally understand why Ubuntu shouldn't be supported here; I agree with that. I also understand why other OS might stay. But i also understand why guys ask about ubuntu here. (For example because they bought the hardware here; they like the guys here and want to share other ideas/projects on other...

other OS on Raspberry
Hallo, I saw a few guys (also at least one engineer) spent - in my opinion - too much time in writing to use an other forum if someone has questions about an other os. Instead of (reading and) writing those answers here again and again, it might be much more useful in supporting Raspbian. This waste...

Re: School timetabling with Pi. Benchmark Pi vs x86
The Pi 4 was tested with gcc 8.3 The Pi 3 and 3+ were tested with gcc 6.3. I can't remember the gcc versions of Pi 1 and 2. I am too busy at the moment to repeat the test for Pi 1 to 3 with latest gcc. Yes, they might be a bit faster; but the values look "more impressive" if is a bit "...

Re: School timetabling with Pi. Benchmark Pi vs x86
Old topic, but i think still not out of date; because schools still need to do their timetables. I also done the benchmark with a 3+ some time ago and also with a Pi 4 today. Results: 4min 36s - Broadcom BCM2711, Raspberry Pi 4, ARM Cortex-A72, 1.5 GHz, Raspbian, Volker Dirr 7min 45s - Broadcom BCM2...

Re: School timetabling with Pi. Benchmark Pi vs x86
Pentium M 1600 is also over 12 years old. A bit unfait comparison. My first laptop was also a Pentium M 1600. It had 1,6 GHz only if it was connect to a socket. With battery it slowed down to 1.2 Ghz. I runned the benchmark also with that computer ~6 years ago. The bad stuff was, that the benchmark ...

Re: School timetabling with Pi. Benchmark Pi vs x86
Oh. Sorry. I didn't repeated it:
use = school timetabling (with FET)
which x86 = see the link in the previous mail. there is a list of some CPUs. So you can compare it.
compared with an 12 years old pentium 4 the new pi 3 is ~30% slower.

Re: School timetabling with Pi. Benchmark Pi vs x86
I done a benchmark with the Pi 3. Very impressive, since i didn't expect that it is nearly 2 times faster then the Pi 2. Still slower then x86 CPU, but the perfomance might be good enough for many schools now. I hope Pi 4 will have a similar speedup next year :-) Full results are visible in the firs...

MPEG2 Patent expires this month
I read that the MPEG2 patent expires April 27, 2015.
See:
http://www.mpegla.com/main/programs/m2/ ... 2-att1.pdf
So the MPEG2 key in the store will be free soon?!

Re: Is the Pi Store down?
I wrote to IndieCity so far only. But no response.
I didn't wrote to RPF.
Maybe i just have got to less experience - as you can see i wrote only a few posts yet.
I don't think RPF will listen to a rookie with a drastic suggestion.

Re: Is the Pi Store down?
In my opinion it look like an intermittent "bug" that you are still able to update. Why? A lot of reasons: - The GUI of the store is bad. Missing pictures, bad style, ... - There are missing basic features like deleting an app (and this was requested already years ago) - I still can't down...

Re: School timetabling with Pi. Benchmark Pi vs x86
I done a benchmark with the Pi 2. It is around 4 times faster then the Pi 1, but still slower then x86 CPUs. (see http://lalescu.ro/liviu/fet/forum/index.php?topic=166.0 )

Re: School timetabling with Pi. Benchmark Pi vs x86
Liviu (main author) and me tried several algorithms. Genetic, Graph colouring, ... But the quickest and most flexible (if you want to add new constraints) we found so far is the current algorithm (Liviu found it). You can read more about it here: http://lalescu.ro/liviu/fet/forum/index.php?topic=444...

Re: School timetabling with Pi. Benchmark Pi vs x86
Ohh... Sorry. My bug. Your are right. Please strike the word "other". About other ARM: I sadly haven't got other ARM CPU at the moment. (ok, i have got one in my smart-phone, but i am currently not clever enough to compile on my smart-phone and i am also not clever enough to cross-compile....
