Modern is relative. F-22's first flight was 1997. F-35 development started in 1992, first flight of X-35 was 2000 and F-35's first flight was 2006. There is absolutely noting wrong with using old technology. Being modern just for the sake of being modern is wasteful.

The only storage medium I can spontaneously think of where 1s are heavier than 0s is punch cards. I hope that is not the current primary storage method in the aerospace industry.
Now you've got me thinking about a hash checking algorithm by weighing the punch cards hah
However, you can get any number of additional bits by suspending the punch card from various locations along its perimeter, and measuring the angle at which it hangs.
Basic Qualifications: • Bachelor's degree in Engineering, Computer Science or related technical focus. • Experience in COMM and Navigation. • Avionics experience • Experience with aircraft operations. • Microsoft Office I love the MS Office req at the end. "Yes, we see you've got a BS in engineering, you're an expert at avionics and COMM control systems, but do you know anything about MS Word?"
I don't see much point in asking for an office package in a job advert. But a lot of jobs do require use of these packages and the level of skill can be terrible in otherwise highly trained people. If you use the apps a lot you should learn how to use them properly, and a lot of people just can't be bothered.
One time, I was given an Excel doc with a bunch of numbers and totals and averages in. I updated some values, only to find none of the calculations changed. The creator simply hadn't used any formulas, or had pasted it all in as plain text from some other place!

This is not Reddit. I know because I am often confused myself.
No, this is HN. It's the same people as Reddit only being pretentious is somehow fine here because we're special?

More like: "We ended up hiring the guy most competent at MS Word at the expense of everything else, because out of the five requirements it was the only one the managers doing the interview knew anything about". "Johnson! We're promoting you to head technical flight operations. We can't believe the level of your MS Word skills!" "Senator, we have no idea why the F-22 inexplicably crashed.

The guy that designed the flight control surfaces of the F-22 did so using an elaborate Excel spreadsheet powered by 4,000 lines of uncommented VBA filled with aerodynamics equations, and he retired 3 years ago.

ISTR that the avionics code is written in Ada, and runs on top of Intel i960 processors, and that the Ada compiler for that target only runs on VAX/VMS (not even OpenVMS, but specifically VMS on the VAX).
Anyway, the processors in the F-22A are a mix of different cores. The power supply in the Gen 3 radar used a MIL-STD-1750A processor. The PICC[1] processor modules also used the MIL-STD-1750A originally, but moved to a newer processor in a refresh (if I remember correctly). I don't know what the non-Raytheon components of the plane were using.
As for the compiler, you are spot-on. We had a MicroVAX in a vault (it was a cleared computing system) just in case we needed to recompile the embedded software for the power supply controller.
[1] Unfortunately, I don't remember what this acronym expands to.
