Windows is definitely part of the problem, but I agree it's not the problem. Linux or MacOS are not better enough either.

My god, I cannot second this enough. We talk craptons about "innovation" and torrents of words on "cybersecurity" yet underpin daily life on recursive kludges on 1980s operating system and software technology. It's

The F1 analogy is easy to use against this line of argumentation. Today's F1 cars are way faster than their predecessors. They are also safer, more automated, and in large part faster because they are easier to drive. The racing is

Well, there does seem to be a special Silicon Valley version of this where people get incredibly wealthy from their software/web businesses and conclude all they need to do is get into <some other radically-different field> and t

> More are employed coding Ada than Rust. > More code Forth than Rust Not trying to be a dick, but do you have any evidence you can point to for these claims? I find them to be surprising and unlikely.

Even as a product of one of those schools, I think the comparison against CA might be going a bit far, but as long as we're talking perceptions/stereotypes... In Aerospace, within both U.S. government and industry, midwest enginee

There was historically a push along these lines (Ada as official DoD language for the software on the systems it buys). I don't have the whole story as to when and how this stopped being a requirement (1990s?), or if it was ever a true

It's been ~a decade since I was knowledgeable in SpaceX software development details, but at least then, they were not the kind of shop that emphasized rigor and formality. Their culture is oriented toward rapid implementation & t

Yes, there's a high likelihood we could make improvements in the laws. No, that would not address the reasons why accountability in law does not yield accountability in practice. ncmncm is right. The Executive branch is not going to

The sweet spot for civil supersonics from an aircraft design standpoint is less than Mach 2. You can maintain good propulsion system performance without variable geometry inlets, boom strengths are lower, aeroheating loads are lower, fuel

NASA does publish on much of its research. See, e.g.: https://ntrs.nasa.gov/ There are other forums in which they publish export-controlled information. They patent things for at least two reasons. One is monetization - s

From the article: > the claim that hypersonic weapons can reach their targets faster than existing ballistic missiles The majority who are seriously working in these fields do not advocate for such systems based on this class of claims.

People are not interchangeable parts. If you have high-output staff in a high cost-of-living area, the strategy that recognizes this does what it can to "keep the band together" and keep them doing good for the company, not just

While you are correct, Elon's point is about "the writing on the wall" and in that, he's on point. Other than the small (OK, small-ish, given Virgin Orbit) startups, most aerospace companies are leaving CA or not bother

Anyone that wants to order a reusable RS-25 can have Aerojet Rocketdyne configure and manufacture it that way. See also the AR-22 variant used on the ill-fated DARPA XSP program. The real issue with that engine isn't its reusability,

To answer this, you'd need to compute the costs of the up-front engineering associated with trying to re-certify as a new type, and also the costs of the modifications. Additionally, there's always negotiation in the certificatio

This reflects a lack of understanding how the U.S. Government works. There's essentially zero chance your statement is correct. There will be changes made to the aircraft, changes to training regimen, multiple reviews, etc., but the
