Re: Has anyone been able to get glfw running?

I googled this example: ... Interesting. I just had it work even without the GL driver enabled in raspi-config. Which seems to crash BTW. Once I enabled it and rebooted the machine seemed generally more sluggish. Then I tried to open a 4.3 meg JPEG I'd just taken in qiv and got booted out of X. Reb...

Re: Has anyone been able to get glfw running?

Is the glfw in the debs not worth bothering with? glfw3.png I'm just starting to learn OpenGL, but I know I really want GLES. So I'm reading the OpenGL redbook but taking it with a grain of salt. I don't really want software OpenGL but I suppose it would work to learn from. I just don't want things ...

Re: Failing USB hard drive

I've never bough a refurb, but (going off on a bit of a tangent here), I have bought a few "used" drives. One of which cost me £10 (including postage) on ebay and hadn't been wiped! :shock: I checked the contents and it had a load of files that appeared to have been from an Estate Agents system wit...

About the only GTK I've done is LXDE plugins. This is old but still compiles and all. It's an inspector for GTK, it can read properties of objects, not sure what else.

This is why you don't want to pay much attention to what happens in a 1 hour timeframe. I have a cron job running that fetches the price every 10 minutes.

Website download page - why no file sizes?

On the page at https://www.raspberrypi.org/downloads/raspbian/ it would make sense to me to have the file sizes, at least as kilobytes, in the blocks of info about each file. It's one more thing to update when you post a new version but not as demanding as the SHA-256. I'm glad there's a third choic...

Sneak peak at the new version. Don’t worry, the color choosers are active, you don’t have to live with these colors. Not sure about the alpha yet so the price text doesn’t obliterate the price trace. The text is drawn last, I think I can at least make that changeable. The font size is changeable in ...

Re: Why didn't we go with Mali?

Yeah, all of the Beagles look great on paper, but often disappoint on final performance. If you can find a use for the PRUs they can do incredible things, but they're typically slower than a Raspberry Pi Zero for everything else. They're also hampered by even more proprietary code and licensing tha...
