The hang is most likely due to vertical sync. The way that monitors work is that the monitor requires a very specific timing for drawing. These timings are synchronized with horizontal sync and vertical sync. Horizontal sync is signaled when the monitor is finished drawing a horizontal line on the s...

Don't forget to go into raspi-config and enabling experimental OpenGL drivers under the advanced options, then restarting the Raspberry Pi.
Not doing so will cause the rendering to be done on the CPU, which is horrendously slow.

I agree! Problem is human psychology too: test shows that people have tendency to first judge word by its first and last character. So people notice at once that it is "Heater" even when you write "Heaterar" or "Heatr" (especially if it is subject) instead and ""Aheate notice fastest. This is exact...

What amuses me with this entire scenario is that someone just nonchalantly hooked up a Raspberry Pi into NASA's network. What was he trying to achieve, anyways? It sure as heck wasn't a hobby project he was working on.

it feels like I don't have enough RAM, like if I had 40 opened tabs on my desktop computer Try running sudo sysctl vm.swappiness=10 in the command line and see if that helps. Usually, Linux is trigger-happy with swapping. It is sometimes willing to swap even with plenty of RAM left. The command abo...

I have a Raspberry Pi 7" touch screen, but I haven't really used it much. It was originally for a project to replace a sea chart (they are absurdly expensive), and while it worked, it unfortunately wasn't good enough because we couldn't find a good sea map, which lead to the image being very blurry....

You can write a systemd service that runs on start. Based on your scenario, a service like this should suffice: [Unit] Description=Start script [Service] Type=oneshot RemainAfterExit=yes ExecStart=/usr/bin/sh /path/to/script.sh [Install] WantedBy=multi-user.target Create a file named start-script.se...

There's even some running on Raspberries https://www.raspberrypi.org/forums/viewtopic.php?t=131201 Awesome! I had no idea that people were still developing these (I thought they all of them were just old servers that has been running for years). Old technology like this must be very lightweight, so...

Recently, I've been looking into old BBS servers on telnet , and it's interesting to see that they are still used even to this day (although nowhere near as much as they used to be). Does anyone remember these old servers? I think it's just interesting to occasionally go back in time and look how th...

Hey, all! I'm a software developer with a bit of knowledge about hardware too, and I've been using my Raspberry Pi as a main computer after my old one broke. The primary reason being the price; I didn't have a lot of money to spend as I'm still studying, and because of that I needed something cheap....
