Small correction: contrary to what the post claims this does not compile:

    fn main() {
        let s = String::from("hello");
        foo(s);
        println!("{}", s);
    }

    fn foo(le_string: String) -> String {
        println!("{}", le_string);
        le_string
    }

This does, which is probably what the author meant:

    fn main() {
        let s = String::from("hello");
        let s = foo(s);
        println!("{}", s);
    }

    fn foo(le_string: String) -> String {
        println!("{}", le_string);
        le_string
    }

Great post!

Amazon makes it easy to sell especially with FBA. That's as much a good thing as it can be misused. It allows new businesses to get started when they cannot afford to handle shipping to customers themselves.

So it turns out the default on Debian is mawk which does NOT support Unicode. Thanks for pointing that out. This simple test gives different results for gawk and mawk.

  $ echo 'ö' | awk '{print length}'

I believe no distro actually ships this version of awk by default. They ship GNU awk which has Unicode support anyways.

Even though I'm a prospective developer I read the title as "realizations I had when writing in a public library". I was hoping for tips or insights when working in public spaces.

Maybe if we'd do it more software would actually learn to deal with it.

Some banks in Germany support chipTAN which doesn't require a phone. You can find a list of banks supporting chipTAN here: https://www.kostenloser-girokonto-vergleich.de/diese-banken-...

SWD is purposefully exposed on that board and instead of flashing via the bootloader I got flashing with gdb via SWD with the `load` command working. I just use a male header with some jumper wires for the connection. It seems stable enough. Some pictures of the debug port here:

It stands for "Transaction authentication number", in Germany this term is widely used, not sure about other European countries.

And yes you are correct, this is a one-time password you enter to authenticate a bank transaction.

Nice series you got there, I just took a look and found some really interesting projects. I would be honored for my article to be featured there!

Fair enough, my first idea was actually to use MicroPython. With a megabyte of Flash that would have been possible, but 64K is just not enough.

On-chip debugging with OpenOCD was actually one of the next things I wanted to try out with my drone. I need to get an ST-Link dongle because the drone doesn't have one on board.

I'm not sure if JTAG will even work or if they connected a pin to some sensor or similar on the board. SWD will work for sure, I saw the two SWCLK and SWDIO connectors on the board.
