Maybe this is what you're referring to. There are similar examples where people do this with old disk drives and printers too.

The speed of light in a vacuum is always the same, but not through dielectric media such as water or glass. In diamond it is less than half the speed.

You can generate yourself a free Libero Silver license, which needs regenerating every year, but yes flexlm is annoying.

Software engineers can sometimes find it difficult as with a HDL you (should) describe hardware that exhibits the intended behaviour, rather than just directly describing the behaviour.

HDLs have familiar syntax that makes it seem like you can just program algorithms imperatively (for loops, if statements, functions etc) but it's all just a mean trick to catch software people out, and generally won't give the results you expect.

On top there's then the fact everything happens at the same time, the faff of making everything synchronised and making sure it meets timing and fighting the frankly awful tooling every step of the way.

Once you get it, it's fine, but you have to unlearn a lot of software muscle memory and keep the actual design work (boxes and lines) almost entirely separate from the implementation (typing your boxes and lines into a text editor).

Have you tried the Emacs gdb mode?

Airborne Electronic Hardware Design Assurance: A Practitioner's Guide to RTCA/DO-254 by Randall Fulton and Roy Vandermolen

Might sound a bit niche, and it is, but even if you ignore the stuff about actually certifying stuff to fly, it has some extremely useful and interesting tidbits about how to go about running very large and highly complex hardware/firmware projects in safety critical industries.

The chapter on requirements is especially useful, and the whole thing is written in a (relatively, for the topic) light-hearted way.

Not immoral, just more culpable. Is it immoral not to kill oneself as being alive makes one more likely to kill someone?

>Except it was never claimed to be any of those things.

Not by its inventors, but by its management-type evangelists. Which do you think the mayor had in his ear?

He might've paired a bluetooth keyboard to your phone at some point.

I love seeing teardowns of old space tech. Having worked on safety critical projects I know that if something is proven and works it is generally not replaced unless something substantially better comes along, so I wonder if the soyuz still flies with these electromechanical wonders.
