Once worked on a project that was regularly compiled by each developer/tester on their respective company laptops. The laptops had a weird mix of "security" software that "battled" each other in the background. Took

I have worked on several but can't go into much detail. One was a big industrial machine with a control software with 7-8 digits lines of code written in assembly language, some FORTRAN, some Ada, distributed over several processors. P

Registers asr22/23 contain a cycle counter that you can use to time stuff. If it's not present, there's a register in the DSU that counts cycles but that requires an access via the AHB bus. You can measure a lot of things wit

There is a finite number of register windows, usually 8 but only 7 can be used because the 8th serves as "sentinel" to detect over- and underflow. Once register windows are full (a function call wants to activate the next register

The Gaisler drivers are hideous if you're doing anything more serious than basic interface testing. Good that you are rolling your own. Consider the -mflat compiler option which can improve timing jitter and reduce memory pressure by a

Tip for your GF: always have another "card up your sleeve" when searching for opportunities. If you solely focus on the option at hand its easy to be disappointed when it doesn't work out and to dwell on it. But if you alread

Sorry, this goes a bit beyond bullet points - In my opinion, this happens when people think they can work in parallel to the "formal" process because they don't need it, they are smarter then people who came before who figure

I think your approach to code review is in general a good idea but don't underestimate the differences in skill level in the average project. I often work with domain experts who are not developers or beginners who are still learning b

It didn't fail "due to software", it failed because the analysis wasn't redone, that came to the conclusion that range checks, as specified by the Ada programming language, can be disabled to increase performance.

Requirements serve to define the goal/agree on what's in what's out. If that can't be spelled out in sufficient detail (regardless of form), production shouldn't begin - make a prototype (or something else that help

I don't know how exactly you'd do that and depending on the project it might be fine. One important feature of a requirements tool is that it allows you to "tag" a set/document of requirements with a version that co

Different terms for the same concepts. You could call it high- and low-level requirements, customer/supplier requirements or requirements and specification. While the form is important, a common understanding is core to be able to wor
