Re: Pi3 - USB boot

I discovered (months too late) the rootdelay=10 option you can put in your /boot/cmdline.txt. This tells the system to expect up to a 10 second delay for the root filesystem (the one set with the root= earlier in the line). I've had maybe a dozen crashes over 6 months because when I'd walk away from...

Re: Force a full fsck on reboot, ignoring the dirty flag

Simpler method, thanks to Redhat: cd /, touch forcefsck, reboot. May need some sudos in there. I created the file /_forcefsck as a reminder: If you do: cd / touch forcefsck At least in Redhat this will force an fsck to run on boot before the partitions are mounted. Very useful for when things are ac...

Re: Why didn't we go with Mali?

I did find the RPI OpenGL tutorial at https://github.com/peepo/openGL-RPi-tutorial eventually. My suspicion is that peepo is AKA petero AKA Peter Onion who's a regular here. I'm pretty sure that peepo isn't PeterO. I eventually figured that out, Peepo on Github is also peepo here (same picture used...

Re: Why didn't we go with Mali?

Sounds like a mess, and now I can begin to see why a guy at Armbian was complaining about the diversity of Arm machines. It's like they evolved in zillions of different directions. To pick one to work with makes you incompatible with the rest. In 10 years or so it'll probably all settle down, until ...

Re: Latest Version of Firefox(and Thunderbird) on a Raspberry Pi

The scary thing is that Github, Sourceforge, Facebook, Paypal, Badoo have gotten it into their heads that they have to run bleeding edge HTML5 and leave it up to the consumer to try to keep up. Having a User Agent switcher plugin helps a little. It's an incredible amount of wasted time and effort. B...

I have half a dozen Pis now which nominally have vc4s (the degree in the Zeros is debatable). This statement is confusing. Are you trying to say that the VC4 in the Zero is a lower spec than the VC4 in other Raspberry Pis? I think I've only used my Zeroes headless for text so I don't know. They hav...

The internet is not the problem. No, the WEB is the problem. That is HTTP and web servers and especially web browsers.
