ModemManager. You need to set the variable ENV{ID_MM_PORT_IGNORE}=“1” I. A udev rule. Standard usb serial ports show up as ttyACM#, whereas nonstandard ports that require a driver like ftdi show up as ttyUSB#. Modems tend to be standard usb

The Rust runtime will, at a minimum, set up the stack pointer, zero out the .bss, and fill in the .data section. You're right in that a heap is optional, but Rust will get very cranky if you don't set up the .data or .bss sections

It’s normal if you use the Nvidia proprietary driver. Every notification leaks one fd, so if you get a lot of notifications it’ll segfault once or twice per day. This was apparently fixed in version 590 of the driver which was released only

If you run pw-top, you might see errors accumulating. This is usually due to an underrun from the game requesting an audio quantum that’s too low. The fix is: mkdir -p ~/.config/pipewire/pipewire.conf.d && echo

I really wish this 3D Gerber viewer worked: https://www.zofzpcb.com/ You can feed it the output from Kicad, and if you include the ipc netlist it’ll even generate models. Great for doing a check before manufacturing, especi

I know Altium doesn’t work, which is very important if you need to provide someone else files in Altium format. If you just want to work on designs there’s always Kicad, which is increasingly very good! But it can’t save in Altium format, a

OVH is awful for this. I’ve given up trying to use their site and always have to open a support ticket any time I want to give them money.

That's 600 mA at 3.3V. USB should be fine, but of course you need the capacitance to deal with that. Radio PAs can be power-hungry beasts.

To clarify for the people questioning the price: it’s $74 for the version with free upgrades for one year. The “Lifetime” version with updates forever is $494.

The dongle was an AAUI connector off of a dedicated port. AUI was a standard, but unfortunately it was the same connector as the video connector. So Apple redesigned it. https://lowendmac.com/2007/apples-aaui-ethernet-c

Where I am, most of the noise comes from air conditioning and physical plant equipment from neighbouring buildings. Cars aren't that big of an issue. Buses can be loud, but they're transient.

The problem with Wave was that it requires a network effect to be of any use, and Google was very stingy with invites early on. Interest had died down by the time they started allowing more people to join.
