In general integer division is implemented using a form of long division, in binary. There is no base-10 arithmetic involved. It’s a relatively expensive operation which usually requires multiple clock cycles to complete, whereas dividing by a power of two (“bit shifting”) is trivial and can be done in hardware simply by routing the signals appropriately, without any logic gates.

The metric standard is to measure information in bits.

Bytes are a non-metric unit. Not a power-of-ten multiple of the metric base unit for information, the bit.

If you’re writing “1 million bytes” and not “8 million bits” then you’re not using metric.

If you aren’t using metric then the metric prefix definitions don’t apply.

There is plenty of precedent for the prefixes used in metric to refer to something other than an exact power of 1000 when not combined with a metric base unit. A microcomputer is not one one-thousandth of a computer. One thousand microscopes do not add up to one scope. Megastructures are not exactly one million times the size of ordinary structures. Etc.

Finally: This isn’t primarily about bit shifting, it’s about computers being based on binary representation and the fact that memory addresses are stored and communicated using whole numbers of bits, which naturally leads to memory sizes (for entire memory devices or smaller structures) which are powers of two. Though the fact that no one is going to do something as idiotic as introducing an expensive and completely unnecessary division by a power of ten for every memory access just so you can have 1000-byte MMU pages rather than 4096 also plays a part.

Open primaries invite strategic voters to sabotage the party they want to lose rather than supporting the candidate they want to win.

Of course you can still do that with closed primaries—you just have to register as the party you want to vote for in the primaries, ignoring your own preferences. Nothing forces you to vote for your registered party in the general election. It’s slightly more involved this way since you would need to change your registration more frequently, and commit to it earlier, but that isn’t much of a hurdle.

Personally, I’d love it if Democrats became the right-most party by staying exactly as they are, and a new party breaks off of them or evolves out to their left.

I’d say it’s more likely to go the other way, with the more moderate or right-leaning Democrats breaking off to form their own party and perhaps steal away the more moderate Republican voters. There are a lot of voters who would naturally align more closely with traditional Republican political views voting Democrat only because the Republican party has been taken over by a radical faction. Having laissez-faire fiscal conservatives and outright socialists in the same party isn’t really sustainable long-term; there are too many critical points of disagreement.

It is just as ridiculous that Republicans in California have little say in the presidency as Democrats in Wyoming.

The Republicans in California have a better chance of seeing a Republican president with the electoral college than they would with a national popular vote, even if their particular votes carry less weight. In a sense that gives them more representation in the end, not less—their voices are ignored but they get what they wanted anyway.

Bingo. They could do it themselves, but they want to spend other people’s money, not just their own. Same as any other tax. Bonus PR points for appearing “generous”.

These are protesters, not terrorists. A reputable news agency isn’t going to take sides one way or the other. The reporting should be structured more like a debate, with both sides allowed to voice their positions in neutral language and offer a rebuttal.

If you can easily tell which side of the issue the presenter is on you’re seeing an opinion piece, not news.

Your intake of sugar participation in extreme sports absolutely impacts other people when you end up with chronic health issues that other people have to help pay for.

It’s not as if there’s some natural law obligating you to pay for anyone else’s health issues. Your government is responsible for externalizing that private cost onto you and others, effectively subsidizing risk-taking and irresponsibility. If you don’t like it, insist that people pay for their own health care and insurance at market rates, without subsidies.

Nothing says that the owner/buyer of a car has to be the one who drives it. You could buy a car and have someone else drive you around. Or just buy one for someone else to use—for example a parent who doesn’t drive could buy a car for their child who has a license. Or vice-versa. Either way there is no reason for the buyer to need a license.

Except it’s not even that indirect. The government of Texas invented this novel class of private liability, and their courts are the ones enforcing it. That’s the same as banning it themselves, and blatantly unconstitutional.

I’m a bit surprised they didn’t implement this as a tax. That would be just as bad, but the federal government has a long history of imposing punitive taxes on things they aren’t allowed to ban; it would have been harder to fight it that way without forcing an overhaul of the entire tax system… and politicians are so very fond of special-purpose taxes and credits.

So you’re not remapping the source ports to be unique? There’s no mechanism to avoid collisions when multiple clients use the same source port? Full Cone NAT implies that you have to remember the mapping (potentially indefinitely—if you ever reassign a given external IP:port combination to a different internal IP or port after it’s been used you’re not implementing Full Cone NAT), but not that the internal and external ports need to be identical. It would generally only be used when you have a large enough pool of external IP addresses available to assign a unique external IP:port for every internal IP:port. Which usually implies a unique external IP for each internal IP, as you can’t restrict the number of unique ports used by each client. This is why most routers only implement Symmetric NAT.

(If you do have sufficient external IPs the Linux kernel can do Full Cone NAT by translating only the IP addresses and not the ports, via SNAT/DNAT prefix mapping. The part it lacks, for very practical reasons, is support for attempting to create permanent unique mappings from a larger number of unconstrained internal IP:port combinations to a smaller number of external ones.)

I’m fairly certain that last one is UB in C. The result of an assignment operator is not an lvalue, and even if it were it’s UB (at least in C99) to modify the stored value of an object more than once between two adjacent sequence points. It might work in C++, though.

Allegories aside, the Bible definitely has a few LGBTQ characters, even if they’re not portrayed in a very positive light. I suppose that means they’ll be banning the Bible from school libraries? Not to mention a fair amount of historical literature… including anything featuring Leonardo da Vinci, Florence Nightingale, King James (yes, that King James), William Shakespeare, King Richard I, or Julius Caesar.

It will be interesting to see whether this makes the history classes easier, for lack of material to cover, or harder, for lack of references.
