Obscure screw added so appliance cannot be disassembled (lemmy.world)

Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.

If you have a Dremel, I bet you could take out the center bit and use a regular slotted screwdriver.

Yeah in the fall, it’s the only dying-looking tree in an evergreen forest

I’m not sure, there was a ton of light pollution where I was at. It was all over the sky in every direction and moved around.

After it started getting dark. It was very vivid around 10:30ish to 11:30 or so. I went to sleep after that though, so it might’ve gotten brighter. I was checking periodically earlier but wasn’t seeing anything til it suddenly became visible.

It shows the space weather forecast. I think it was G4 last night.

I was running out of RAM on my 16GB system for years (just doing normal work tasks), so I finally upgraded to a new laptop with 64GB of RAM. Now I never run out of memory.

[Resolved] After updating through both APT and the Software Store, I can't play mp4 videos with VLC anymore. The screen goes blank for a second or two then the audio starts playing without the video..

I’m using Debian 12, Ryzen 7 5700X processor, and Radeon HD 5450 graphics card. I have tried uninstalling and reinstalling VLC but it didn’t resolve the issue. Here’s an excerpt from the VLC’s log file:...

Can you turn off hardware decoding and see if it works then?

I’m not sure off-hand since I’m not too familiar with VLC.

I would imagine it could be an issue in a graphics driver at the kernel (amdgpu?) or user level (mesa?). It could also be a problem in something higher up.

I would recommend posting an issue in the VLC repo and see if you can get better support that way.

I use it all the time to help simplify long excerpts, giving me an introductory gist of what something says.

You could write C or assembly and it would be compiled to something that would run on an embedded chip. They may or may not be running an RTOS.

Learned how drivers worked and fixed a driver for an USB to I2C chip. It’s still buggy but at least it sorta works now.

Some more details: I was using a CH347 (USB to UART/SPI/I2C) and there was an open source driver that used a previous chip version. The original dev had hardcoded the bulk IO endpoints indices. The only change I had to do was just iterate over the endpoints and search for the correct ones. But at first, I didn’t understand anything about how the USB subsystem worked and how drivers were loaded. All I could tell was the USB device was correctly detected but the I2C driver wasn’t being loaded, despite proper udev rules, correct vendor/product IDs, etc.

If you have a memory-mapped peripheral where there’s a readonly register, I could see it being const volatile.

This is being used in a LoRa module (it’s a Reyax RYLR896 (which is not great for my purposes ngl)). The STM32 acts as an intermediary between its UART interface and the LoRa module’s SPI interface, basically doing some rough translation and some encryption, nothing major. I believe the LoRa stuff has its own crystal, so I would imagine there is no need for an external source.
