The Avrocar! It turned out to be ridiculously unstable at any regime outside of low-speed ground effect.

I was actually thinking of this contraption: the Hiller Model 1031-A-1 Flying Platform. Less extraterrestrial, but endearingly deranged.

Holy poo poo. I get where they were coming from but once they got to the model stage someone should have pointed out that it was a dumb loving idea.

It wasn't that long ago that b52s were using reel to reel tapes for some on flight computer functions and relatively recently replaced with an emulator that functions the same way.

They moved to C++ for the F-35 and that has been a source of problems. As for chips, you've gotta run with what the programs were written for, otherwise you have to update the code to the new architecture, recompile everything, and then recertify everything. Unless you're like the French and make your programs run in a VM so you can change the hardware without affecting the software beyond the VM itself.

Moving to C++ from Ada is probably a very smart move. At this point I'm betting there is enough tooling out there for C++ that you can probably get a lot of the guarantees Ada gives you, if you want. But I've never used Ada.

Reuters has a non-story on China Naval Capacity That story is "They are building a big naval shipyard for the construction of large naval ships." Also the well nigh apocalyptic revelation that China intends on building more than one aircraft carrier It's very weird

I'm pretty sure this crazy project was a (relatively) more sane replacement for their crazy jetpack infantry project. Because as bad as that thing is, it's still more stable and more easily controlled than an early 50s jetpack.

I think Congress is still hashing out the 2020 NDAA, which will allocate the money for buying F-15EX prototypes. Last I read, the House version only authorizes 2 of them, down from the 8 the Air Force originally wanted. Dunno about the Senate version.

The oldest variant of the E-2C still in operation uses the same computer-emulating-a-tape-drive setup as the old AWACS. Plus the operator interface is like something straight out of the Apollo era.

shame on an IGA posted:Do the AWACS computers still have magnetic core memory or did they finally get the space shuttle upgrade? The Block 30/35 (E-3B/C) jets have the same system they got in the 90s to emulate the reel-to-reel hardware. I don't know if that's what you're talking about or not. The 40/45 (E-3G) is using a COTS Windows-based system, so I assume it's Edit: The 30/35 computer is programmed in JOVIAL I think. Shooting Blanks posted:I thought the USAF didn't even want those 8?

Hauldren Collider posted:Any modern IDE would catch this for you in a millisecond--these things sound handy back when people edited code in text editors. If you're using Visual Studio this does not need to be in the compiler. There’s a difference between having a balanced number of opening and closing brackets versus intentionally closing the right blocks.

VHDL (one of the two main languages for designing integrated circuits) is based on Ada and I much prefer it to the other one, Verilog. It was developed at the behest of the DoD as a way of documenting the workings of ICs which used to be designed in schematic form. It also incorporates an acronym in an acronym which seems like a very military thing to do.
