Re: Default swap file size

My question is should this default value be changed or removed? Seems like the config file hasn't been updated since 2010, and this 100 is a very old (and small) value. To me it also seems to be odd choice. It is too small so it is more dangerous than useful. Once both memory and swap is full it go...

Re: When will the OpenGL 2.0 driver be released for everyday use?

There are two options for the driver kms and fkms. The one called fkms has advantages of both the old and new one and is quite usable for me with raspbian. Anyway, to me it looks like it is in best state it could be in current 'not supported' state and can hardly improve without more wide testing an...

Re: Nanosleep in C gives 60us overhead on Raspberry Pi

Also you could possibly use existing hardware like SPI, I2S, UART to send 'fake' data to generate what you want? e.g on esp8266 I2S was (ab)used to generate tv-out signal.

Re: Raspberry Pi TV Hat DVB-T2 Gateway (Tvheadend with FFmpeg and realtime hardware video stream transcoding)

Just wondering what type of trancoding (resolution? codec types?) is this targeted for? Can this transcode HEVC/h265 to h264 in realtime on pi3b+? Or does it trancode mpeg-2 to h264? Can it do mpeg-2 in realtime without paid HW codec?

The SMSC9514 is both the LAN & the USB you can't disable one without killing both.
You can. And on pi3b+ you can also disable nested hub with 2 usb ports for further saving if 2 ports is enough.

We released as much of the 3D stack as we could (the entire ARM side) as OSS. We (including Mr Upton) got endless abuse how it was a pathetic atempt at OSS.

The thing about the competition is that even if you are skilled at Verilog I get the feeling that creating a new processor core from scratch is going to take more time than is available.
Google for DarkRisc-V, the author claims to do it from scratch over one night.
