Many, many years ago I used to have two Wyse50 terminals, running split screens each with two parts. I did a lot of support on remote systems (via modem!) and I would have a session on a customer system, source code and running on our test system and internal stuff. I didn’t have space for a third terminal.

At another job I had an office with a “U” shaped desk. I would spread printouts across half the “U” and swivel around between the computer and the printouts.

Technically, he would have three drives and only two drives of data. So he could move 1/3 of the data off each of the two drives onto the third and then start off with RAID 5 across the remaining 1/3 of each drive.

Deal with the ethernet port issue by purchasing a 5 port ethernet switch. Maybe the rest of your issues go away?

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.

So write it properly from the get-go. You can get 90% of the way by naming things properly and following the Single Responsibility Principle.

In this case you could view a swap partition as a safety net. Put 20-30GB in a swap partition in case something goes wrong. You won’t miss the disk space.

FORTRAN IV was the first language I learned to program in. Punch cards!!!

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.

Well, there are specific hardware configurations that are designed to be servers. They probably don’t have graphics cards but do have multiple CPUs, and are often configured to run many active processes at the same time.

But for the most part, “server” is more related to the OS configuration. No GUI, strip out all the software you don’t need, like browsers, and leave just the software you need to do the job that the server is going to do.

As to updates, this also becomes much simpler since you don’t have a lot of the crap that has vulnerabilities. I helped manage comuter department with about 30 servers, many of which were running Windows (gag!). One of the jobs was to go through the huge list of Microsoft patches every few months. The vast majority of which, “require a user to browse to a certain website” in order to activate. Since we simply didn’t have anyone using browsers on them, we could ignore those patches until we did a big “catch up” patch once a year or so.

Our Unix servers, HP-UX or AIX, simply didn’t have the same kind of patches coming out. Some of them ran for years without a reboot.

Kotlin is a very easy transition, and it sorts out a ton of issues that you find in Java. Certainly easier than moving to Rust.

Kanban is probably way overkill as a model for what you want. The key about Kanban is control of WIP/Queues at various stages and pulling items through the workflow. With a simple ToDo/WIP/Done workflow, you’re probably going to find any Kanban apps are too complicated for what you get out of them.

I’m not sure that what developers really, really need is faster programming cycles. Most teams could benefit more by controlling the process - from idea to deployed. How much technical debt is incurred because users/customers can’t prioritize features or give accurate requirements, there’s way too much WIP, features are huge, releases are huge and infrequent and the feedback cycles are far too long.

So yeah, as programmers it’s always cool to look at ways to program faster, but what’s the point in programming stuff nobody needs faster? Or programming the wrong things faster?

I’d be willing to be that if you asked any team, “What are the biggest impediments to delivering value to your users faster?”, the answer would be that you can’t cut code fast enough.

I dunno. The title was “Are there really no viable alternatives to PhotoShop on Linux?”. I think it’s fair to say, “There’s GIMP”. It’s viable. People use it successfully and happily. 'Nuff said.

Not me 😭

The last rPi I bought was all of $40. I thought it was a bargain for the specs.

I retired now, but I still write code for my blog. I totally prefer to write with Kotlin. Java just feels clunky to me now.
