Reflecting on all the times in my career as a software engineer I have been told that, yes, things were a bit unfair to me as a woman, but that I was being a trailblazer, I was the one discovering and establishing the path that would enable others to follow.

But you go back to the 70s and you see the same number of women programmers, being fed that exact same line
And in the 80s
and the 90s
and so on to today. The "trailblazer" narrative is a lie told by managers to make themselves feel better

And that's why the boys kicked us out.

That, too is part of the story, and needs to be addressed.

yup

fucking guiding men to the moon, with the computing power of a desktop calculator, and it worked perfectly

i don't know if there will ever be a greater programming tour de force ever again

also: the crew of the ill fated #apollo13 was saved by #JudithCohen, who did the Apollo Abort Guidance System and many other aerospace systems

*and then she gave birth to #JackBlack!*

"In a memorial tribute, her son Neil notes that she was troubleshooting problems with schematics on the day she went into labor, called her boss to let him know she had fixed the problem and then delivered Jack"

@Dianora
Is there a name for the category of programs like the Apollo Guidance System where everything happens by being triggered at a particular time in a cycling clock?
It's a very different kind of program from everything I've ever worked with - e.g., environmental sim models written in FORTRAN and C.

@ohmu Several ways it can be done. Cooperative multitasking means each task does its own thing then starts the next task. Cooperates. Of course if a task hogs or infinite loops that's a problem. Nevertheless with a WD timer it can be done.
Another way is a single task that gets interrupted to do simple I/O tasks.
What you are describing is time slice and is nice for timesharing applications but not so much real time.
Really I've simplified but it's all online if you are curious. I'm too lazy to get up to look at my textbooks. ;) DST took it out of me. (hate it!)

Thank you.
I mostly get this.

@ohmu To keep things responsive for keyboard users, time slices are enforced which is not necessarily what you want for a task controlling how long to fire the rocket engine!.

I'm familiar with the term "event loop". That architecture is common: JavaScript uses it, as does the nginx web server, for just two examples that come to my mind immediately.

In event loop architecture, things happen either triggered by a clock or by some outside stimulus (often: IO available).

There is an OS call named "select" that can be used as the central hub of an event loop. I've myself coded event loops on two occasions in the 1990s; one was based on that. Was fun.

@dj3ei @ohmu IRCD is an "event loop" driven process. It's triggered by I/O. Select, or Poll or kqueue or whatever else mechanism drives things.

always overlooked and snubbed

random example

https://en.wikipedia.org/wiki/Lise_Meitner

"Despite the many honours that Meitner received in her lifetime, she did not receive the Nobel Prize while it was awarded to Otto Hahn for the discovery of nuclear fission... Meitner was the one who told Hahn and Strassman to test their radium in more detail, and it was she who told Hahn that it was possible for the nucleus of uranium to disintegrate"
