Re: Learn C or Python first?

Without actually spending any time reading existing Python code, and only reading some C code, I would venture to say Python will be much more natural to pick up on. My fear is, will it make me more hesitant to get deeper into programming, and learn C? There are many Pythonistas who have extended t...

Re: pygame code optimisation help

Pygame is usually (and recommended to) run without hardware acceleration. That means that it is slow and to make it workable, you should restrict all unnecessary drawing (blitting etc.) and updating of the screen. The cost of these procedures (at least of drawing and updating, I haven't actually tri...

Re: Are more CPU states possible than min/max/locked?

Just out of curiosity: How does your rPi show its unhappiness with making those big jumps between the frequencies? Why is it not happy? Aside from how hot it runs despite sitting at 125MHz 99% of the time (I have the rPi B Gen 1 with the linear regulator and other fun electrical gremlins), I've bee...

Re: Are more CPU states possible than min/max/locked?

Is it possible to enable more steps for finer granularity in CPU speed steps? I think that'd be really awesome, and I know I would appreciate it. It'd make my rPi much happier for sure, seeing as currently it jumps between 125MHz and 1000MHz. Just out of curiosity: How does your rPi show its unhapp...

Re: pimoroni PhatDac No Duplex sound

I know for sure that ALSA in the past could not handle several applications at the same time. It is most probably is like that still. If a program uses ALSA directly as an output that will reserve ALSA output for that program and other programs can't play any sounds through it. You have to use Puls...

Re: New Pi3, hangs

If you do not get the low voltage warning in the right corner of the screen, I suspect that you are experiencing hardware failure when the processor does really much computing. The ways to fix it are: 1. return your Pi as a faulty product and get a new one, or 2. underclock or give the processor hig...

If your usual supplier is charging more, go somewhere else that is charging less.

This is the official price as specified by the Raspberry Pi Fou...
