If someone drops their wallet by accident, and you take it, you are still stealing. The ultimate "source of truth" for payments is not the payment system, but the law, so if a payment was made in error, then the receiver has a leg

I thought it would be a fun challenge to do Advent of Code without actually writing any code! I imposed a rule of no Apps Script (cell formulas only). Fair warning: some of the linked spreadsheets are very large, and may make your browser v

That's a pretty clear line... On the one side, even if the US government is not adequately regulating private companies today, it could begin doing so tomorrow, or if it's a question of legality, any individual or group could brin

I use DDG by default, but sadly it's quite noticeably worse than Google, so I end up having to override it frequently :(

- Code is not prose. It's not read like a book so it's not clear that an "ideal measure for continuous text" is at all relevant. - Most lines are short even if the limit is more than 80 characters, so you're unlikel

There are two "components" to what used to be `msvcrt.lib`: - The C runtime library (now `ucrt.lib` AKA the universal C runtime) - The compiler runtime (now `vcruntime.lib`) The former has a stable API, but the latter doesn't

That's not a great reason to use strings to identify classes though... Why not just give `Impls` a special attribute: class ExampleImpl(Foo, metaclass=Impl): target = Bar Or do the entire thing via a decorator:

Most of the problems with hydrogen for cars comes from how you produce that hydrogen. Obviously, producing hydrogen from methane to power cars is a stupid idea if your goal is to reduce greenhouse gases. However, pure electric cars are only

To be clear, even without `--locked`, cargo will use the dependencies from the lockfile, as long as the lockfile is not out of date compared to Cargo.toml. However, for development, you normally want cargo to update the lockfile after you c

There's going to be a risk to running someone else's code. There are two factors here: 1) Do I trust the code I think I'm running. 2) Am I actually running the code I think I'm running. With (1) there's not really a

That's absolutely micromanaging and negative. The goal of school isn't just to pass the tests. If a kid fails to revise for a test, but it doesn't matter because their parent will just look up the schedule and force them to r

Spanner, CockroachDB and similar are really exciting, but the fact that none of them support stored procedures begs the question of whether it's inherently hard/impossible to do so in a distributed database, or whether that just h

Also, it's not really the case that exceptions (when not thrown) are zero-cost in C++, and not because of the instruction cache or increase to static data size. The cost is that exception-throwing functions inhibit many of the optimiza

The size limit makes a lot of sense when you look at the transaction model. When you write to FDB, none of the writes are even sent to the server until you attempt to commit the transaction, so this limit is actually a "maximum request

pg_upgrade has a `link` option that when used reduces the time take to ~15 seconds. IMO, that counts as "near-zero downtime".

The Azure web console is light-years ahead of GCP's console, it's so much nicer to use. GCP's console is just stupid though. It takes so long to load, and instead of just making it faster, they made it load in incremental

Deleting a database is probably a bad example, but my point still stands: even if you are not trasferring code back and forth, runtime state is enough to be a problem. What if your runtime state includes an `is_authorized` flag or similar

Not that much more complicated - but perhaps that's because you're over-simplifying the case of a household spending more than it earns. As with a household, when spending exceeds income the government has to take out a loan (usua
