  • Looking for Scriptable asynchronous communication tools

    Jump

  • I looked and Python has the library support for the GPIO and to do background threading to poll pins. My preference would be to go with a JVM language like Kotlin, but then I'm a programmer. Python, from the little that I've mucked about with it is really just one step in complexity from scripting. Maybe even easier, because some things in shell scripts are super difficult to do.

  • Maybe then you need to move one stop up from scripting into something closer to actually programming. I'd be surprised if Python doesn't have the library support on a Pi for dealing with both serial and GPIO I/O.

  • the end stop in external to the serial communication

    Does this mean that you have some kind of other signals or pin-outs? If so, this is starting to sound like a great project for a Raspberry Pi, because the GPIO pin array can handle that.

  • Keep in mind that it has been decades since I last used Kermit, but I'm pretty sure the use case it was originally designed for was...

    Connect to a serial port, which had a modem attached. Talk to the modem and get it to dial a number. Presumably, the remote end answered and the port attached to its modem would issue a login prompt. Negotiate the login and then issue a bunch of commands to change directories and then launch Kermit on the remote system. After that Kermit to Kermit communications took over until you terminated the session. Finally, log off the remote system and hang up the modem.

    All of this stuff could be done via scripts. I seem to remember that it would actually wait for a response, and then parse the response in the script. I don't remember ever doing polling loops.

    If you're on a *nix box of some type, it's totally possible to open up a serial port for manual I/O even in something like a bash script. Even if you have to reverse telnet to a terminal server.

  • Kermit on top of FTP can work really well. Kermit has its own communication and transfer protocol, IIRC, but updates in the 1990's allowed it to be used with TCP/IP and FTP. So you can write a script to log into a remote system, run some commands and then initiate a file transfer. The scripting allows you to wait for responses and act on them.

  • More and more people are ditching carrier roaming in favor of travel eSIMs

    Jump

  • Yes, $15 CAD/day to "roam like home". I have an Orange eSIM that I can keep alive if I use it at least once every 6 months - with a local french number that stays mine. It costs me about $40 CAD for a 30 day - 20GB top up. My wife uses Nomad for data only, we both don't need local numbers, and it generally costs $12 CAD for 5 GB 2 week top-up.

    So I figure about $60-70 CAD for 3 weeks travel virtually anywhere in Europe. Calls and SMS included (for one) without long distance charges. Compared to $630 for "roam like home" for two people from a Canadian carrier - doesn't matter which one as far as I can tell.

    We both recently got new phones to be able to use eSIMs.

    And the physical SIMs stay active. So my elderly parents can call my Canadian number if there's an emergency and it will ring through.

    In fact, on our last trip to Rome, when we used a credit card at the hotel, it was refused and then seconds later I got a text from the bank asking for confirmation on my Canadian number. I had no choice but to text "Yes" back, and that single text activated roaming for the day and cost me $15.

  • It helps if you are an old enough Canadian to remember the original "Hinterland's Who's Who" shorts.

  • "Row headers" seems wrong to me. Maybe "row labels"?

  • What are some FOSS programs that you think are a far better user experience than their counterparts?

  • I never expected to see a compiler in this list, at least not in 2023.

    Back in 1988 I realized how rubbish Microsoft was when I discovered Borland's Turbo Pascal and Turbo C compilers. I'd previously used the MS compilers and they were multipass, multi-minutes to finish a compile. The Borland ones were single pass and FAST.

    Back then, compile times could be huge, and everyone was publishing benchmarks on compiled program performance, which mattered on the hardware of the day. I never even think about that stuff these days.
