Re: Am I the only one that still would buy a Raspberry Pi 3b+?

Of course the 3B, 3B+ and 3A are still useful. Adaptors are not a problem for everyone: I need a cable between my Pi and a monitor/TV, I just put a micro-HDMI to HDMI cable, that's it. I have many devices that uses a micro HDMI cable (cameras, tablets, and so on), that's help. I had micro HDMI cable...

Re: Raspbian refuses to use Swap Space

Hi,
Its likely to be a maximum memory per process limitation. Even with many gigabytes of swap, you can't allocate more than a limited amount of RAM per process. But even with a 32 bit OS, it must be 4GB so I can't explain why you are limited to 1GB or so.

Hi,
Probably due to power requirement difference between Zero and Zero W, they had to use a stronger inductor.

Re: Raspberry Pi 4 temperature

Not sure why people think that you can get more speed out of a CPU but still use less power. Effectively, it's a fact : peoples expect more CPU performance for a lower power consumption. It may due to the industry's ads : always more XX% of performance gain and less XX% of power consumption compari...

Re: How to run Freespace 2 Open on Raspberry PI 3

The problem of running newer versions of fs2open is the minimum OPENGL version they need... thats something that may be fixed with newer Stretch versions or in the RPI4. This was also the reason of why i was unable to run mods, because i needed S3TC support, and i never made it to work. Fortunately...

Am I right in thinking Mesa is also doing the OpenGLES for the V3D/VC6? Open source OpenGLES on the Pi4? How long would it take to rewrite all t...

Hello, Everyone agreed that the Raspberry Pi 4 announcement was likely the biggest since the very first Raspberry Pi in 2012. Most interest were focused on the hardware, which is a huge leap forward indeed, but is there also a huge software change, using the open source OpenGL driver, working out of...

Re: Raspberry Pi 4 Thread - general discussion

Out of curiosity : do this new SoC integrates a RTC (with battery pin exposed) ?
It's not a request, I know it's not useful for almost users and for those who it's useful, there is plenty of third party boards out there. But sometimes it's just available on some SoC.
