I always believed the difference between unspecified and undefined behavior was specifically tuned so that unspecified behavior was fine to use un-portably, whereas undefined behavior was never meant to be used. Hence the wording of the sta

I believe that in release mode Rust will remove bounds checks.

Not quite. One of Christie's appointed directors at the port authority closed the bridge. Later the port authority decided to reverse it's own decision. The intro blurb skips the appointed director and attributes the closing of th

It taxes regular people differently than taxing them directly. VAT rates on food tend to be regressive. Taxing company profits has little effect on prices.

Exactly. It's not like it would take compromising the vendor, or the service contract. The install can be a simple and quick swap. The infeasiblity mostly seems targeting and monitization. You have no clue who or what will plug in, so

You get non-canonical representations such as 11=3 You could go multiplicative based. So 11 = 2×3. But then you get very difficult addition, comparison, and you need numerals inside your numerals. (E.g. 2048 would be 11 as in a single 11 in

Premature optimization should be avoided client side as well I imagine? It just seems like lots of development shops skip optimization altogether, even when it stops being Premature (when it matures?). And it's not like those Shops suf

For a long time, I've argued we need leaf certificates to be double signable. That way there can be two chains of trust for a website. Then dropping a CA doesn't matter much, since all serious parties should have multiply signed p

The value of crypto coins doesn't come from technology. It comes from faith in the technology. Inherently value is a social thing, and hence some of what underlies it is social too. Big part of that is the stated intent of a cryptocurr

They don't cooperate for profit, they compete with eachother. Everyone in a mining (or staking) pool seems more likely to count as a general partnership.

For symmetric encryption quantum computing doesn't do much. It reduces the running time of brute-force search by sqrt. So in 2^128 operations you could brute force a 2^256 big search space (i.e. a 256 bit key). That's why many sym

In declarative systems, you want to explain the final end-state. Often your requirements on the final end-state involve some predicate logic. I want (A and B) or C. Using an Or makes sense, if you want your declarative logic to work on both

Could ammonia be used for stable seasonal storage of energy? The abstract suggests that ammonia is much nicer to transport and store than hydrogen. If we can use it to store summer solar to run winter heat-pumps with a low roundtrip efficie

Those statements (not yours) are quite surprising, and seem falsifiable. Anyone have the expertise to judge whether the factual claims are true?

No, he uses numbers from an old regime of rules. Argues those were incredibly safe, and hence the newer stricter rules are unnecessary.

I imagine Monero might similarly not count as a security? The complete lack of scripting helps that argument at least. And the raison d'etre isn't "make money" but "privacy so good even the police can't track y

I feel that the article is arguing against somewhat of a strawman. Not the idea 'chatGPT isn't a general AI' but the idea 'general AI is impossible'. I think I see more serious arguments against chatGPT not being ge

There is a specific benefit to society. It allows artists to live of creating works meant for wide consumption. It means artists aren't limited to those who cater to the rich and those who are rich themselves. Not that I support curren

Ssh keys are much simpler than the PKI cert infrastructure. This has advantages for development, as well as bug resistance. But it means ssh expects every server behind the same hostname to use the same SSH key. You can't get two (well

Perhaps the statement 'banks cannot create loans out of thin air'? A bank can, with some capital buffer, borrow money from the fed, loan it out to someone else, and earn an interest spread. Deposits help here because you pay a dep

That has massive fee friction, does not eliminate counter party risk entirely, and earns different (lower?) rates than the Fed offers.

It's not quite right that banks don't loan out their depositors money. They need depositors to be able to make loans. Stashing depositors money at the Fed keeps the bank from making loans. Stashing money at the Fed is possible by

It's not so much about the loss, its about the fact that banks lose their depositors. It is great for an economy that the 'savings' of people are used to safely invest in good ideas. This is the function of banks, and inciden

The rust NonZeroU64 solution has a subtle 'bug' that happens not to matter. The function fn get_optional_non_zero(n: u64) -> Option<NonZeroU64> let i = n & 0xFF; if i == MAGIC { None } else { No

The risk profile of cash and bank deposits are wildly different, and largely incomparable. It is a personal decision which you risk you like more. Certainly, cash has advantages over bank deposits. My point was that it also has downsides.
