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 devices, so ModemManager by default scans all serial ports as if they were modems. This involves sending some AT commands to them to try and identify them.

Software implementations of serial devices tend to follow the standard, so they show up as ttyACM#.

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.

> One-way messages

Messages are either one-way (Send or Scalar), or are two-way (BlockingScalar, Lend, or MutableLend). For two-way messages, the calling process inherits the quantum of the sending process, so the only penalty is the cost of two context switches.

> Interprocess communication by memory remapping instead of copying

This is true for Send, Lend, and MutableLend, but for Scalar or BlockingScalar you get 5xusize values instead, which is used for things like `msleep` or `uptime`.

You would have to stop access to other threads that might have access to the page about to be unmapped, but Rust guarantees that if you have a mutable reference, you're the only one with access to the page.

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 "context.properties = {default.clock.min-quantum = 1024}" | tee ~/.config/pipewire/pipewire.conf.d/pipewire.conf

Basically, just force the quantum to be higher. Often it defaults to 64, which is around 1ms.

You can load additional symbols into gdb without restarting it by using `add-symbol-file`, which you can use to iterate on the symbol mapping.

I’m not even on a vpn and I’m getting an error saying the website is blocked.

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, and I’m not sure I’d trust it for manufacturing.

The other thing I’m missing is my 3D Gerber viewer called ZofZPCB. I’ve not gotten either it or Altium to even start.

I've never gotten passkeys to work on the Mac. Every time I try it with either Firefox or Safari says I need to log into iCloud, which I really don't want.

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.
