I code on both and they are just for different purposes. E.g. I think it's madness to develop desktop apps in Rust.

Development velocity is way greater in Java.

Why not compiling it to Java source code (not bytecode)? Users would use their own Java compiler then.

Same as, say, ANTLR generates code to parse various texts to AST.

All of that tooling and Rust will always be less efficient than Assembler.

I hate when tools only produce generic "TLS Handshake failed" instead of saying why exactly it failed, where is the problem.

You forgot about NaNs (all of them), infinities and positive/negative zeros. Tests warranted.

Just because you have more features and ways to use them. Say I like to use a different garbage collector for a tool.

> didn't actually do nation building

USA did, at least tried, but it's just not feasible. Sarah Paine described it way better than I can do: https://www.youtube.com/shorts/6d_mQwwiPjM

"Provide a way" -- what if it's way too expensive, even for a huge country? And populace just doesn't want it (e. g. it goes against sacred texts). And there are no infrastructure nor institutions to build upon. It's close to impossible. And the populace would see us only as a provider of goods.

And morally, why should we provide some other country? Are we the world government? Shouldn't we stop messing with others and keep to our business, as long as they don't mess with us (bomb and export heroin). Why are we suddenly responsible for them?

PS: nevertheless, one country (USA) tried to build democracy in Afghanistan, but failed. And only got scoldings for that.

I don't think crime can always be fought through democratic processes. What if the whole country lives on heroin exports (Afghanistan)? Any "processes" are doomed to fail, as populace would vote to feed their families.

Well, it's much better to be on the invading side though. I've been to a coutry that was on invaded side (Ukraine), and, trust me, you'd always want to be on the invading side. And sometimes all it takes is just one invasion.

But when I said "we honor our veterans" I did not speak of USA, I spoke of any country veterans.

Why would you do that (The Merge) to yourself?

Is it really any different than forcing everyone to `git-rebase` their work to the latest (shifting) `main` on Fridays? Then the tool does not matter.

As usually happened (and happens today with git) -- everyone just tries to get their changes merged sooner, so it's the others' person problem to resolve merge conflicts. And that's good for velocity. Why doing it on Fridays only?

Plenty disagreements everywhere. Under (usually fake) ideas of not enough resources for everyone, so the strongest must survive.

Nazi planned to exterminate several whole ethnicities. If you think it was (or is) unversally accepted as "Bad" -- think again. Most developed countries had Nazi parties, including US and Canada. Some sympathize today. Several Middle East governments publicly claim that murders/rapes/kidnappings of people from another particular country is just and honorable, and will be rewarded in heavens.

Ancient Spartans (reportedly) killed their own weak children. In order to become a citizen every Spartan must have killed a man (non-citizen). It was considered good and just (by citizens).

In many cultures tribal warfare was paramount, even before states (and some remote tribes practice it even today). It was considered good and just.

And we honor our veterans, and for a good reason. (Without them, we would be captured/killed by other veterans, and honor them anyway). Modern civilizational culture is a thin patina on top of our primal behavior.

Yes, and stand by it: > All outgoing traffic from AWS is charged no matter what.

Your example with VPC endpoints does not leave AWS.

Sorry for the confusion you probably thought about outgoing from S3, but I mean outgoing from AWS.

SVN in SVN for sure, it's a well made product. The market just didn't like it's architecture/UX that doctates what features available.

CVS is not much different from copying files around, so would not be surprised if they copied the files around to mimic what CVS does. CVS revolutionized how we think of code versioning, so it's main contribution is to the processes, not the architecture/features.

Naah, the moment the first million of those is sold -- the price crashes.

In other words, imagine some investor had those billions, and could buy the key. Should they? A thing is worth as much as someone is willing to pay for it.

S3 GET operations are billed anyway.

Traffic may be free, but not the operations.

> directly streamed from the underlying S3 bucket, which is free.

No reads from S3 are free. All outgoing traffic from AWS is charged no matter what.

And that's why it's harder (or easier?) to make the same landing again -- we taking way less chances. Today we know of way more failure modes than back then.
