I was definitely that kid. I remember discovering that my district's web filter had a default password (something like "changethis123"), by watching one substitute with exceptionally poor typing skills. Problem was, substitutes' accounts were disabled frequently, and any one account only really had a lifetime of a week or two, before someone in the IT department realized that 300 devices were connecting to the network with the same credentials.

But the staff lists were public, and I had the default password. So I set up a script to turn the lists of names of teachers, librarians, janitors, etc. into usernames, and then tried to login with all of them. Turns out, most support staff, especially custodians, hadn't changed their passwords. (I'm guessing their jobs didn't involve much computer use). With a list of a couple dozen working accounts, I'd mete out 1 or 2 at a time to my friends, and we had teacher-level access for the rest of our time there. Don't remember using it for much, maybe showing my friends a youtube video during lunch or something.

Why does a fitness tracker need continuous development? How on earth is something whose main competition is a $5 notebook and a $1 pen worth $50/yr?

A fitness tracker is exactly the sort of software I would expect to pay once for. It doesn't need some compute-heavy backend. It shouldn't need any backend at all. The entire application is window dressing for a SQLite database.

If you violently bust into someone's home in the United States, you're liable to, and absolutely deserve to, get shot. I do not care if you have a badge. If you want to execute a lawful search warrant, the best time to do it is when nobodies home. The second best time is during the day, when you can clearly state your legal mandate to be there, and allow the homeowner to comply.

The ATF in this instance (and frankly most instances) chose the most violent option available to them, because good people don't join the ATF. Violent thugs who get off on shooting dogs join the ATF. And when they get tired of shooting dogs, they decide to manufacture a scenario where they get to kill a more dangerous game.

In the US, most unions are majority unions, i.e., they unionize an entire workplace by majority vote, and then demand that the company allows them to require all hired employees to belong to the union. Hiring scabs is a breach of contract, with the added weight that unions have extra protections ( for example, you can't just fire anyone who talks about unionizing. That's big illegal).

Besides the legal protections, the primary leverage a union has is the fact that in manufacturing, agriculture, etc., companies start hemorrhaging money if work stops. So a relatively short strike (and thus more easily weathered by the members) can have a massive impact. This worked even before there were legal protections for unions, because the union can strike faster than the company can hire scabs. Of course, prior to the protections, companies could decide that taking the hit was acceptable, and then just hire a bunch of scabs to replace the workers. Or they could threaten the union leaders with violence. Which of course lead to the unions using threats of violence against management and the scabs.

After a couple decades of increasing hostilities, accelerated by the re-introduction of a bunch of combat trained WWI vets back into the workforce, the US established a robust set of worker protections to eliminate the necessity of violence.

Translated: Management ("wasn't represented due to job classification") doesn't like unions. Shocker.

Due to this, back when Hong Kong was under U.K control, a person born in North Ireland to a Hong Kong resident could claim 3 birthright citizenships: U.K., Ireland, and China.

You're making the assumption that the change in absolute terms is entirely driven by deficient additions to the population. It's just as possible that some portion of the population lost their skill by allowing it to atrophy from underuse.

If breaking the law is immoral, what are we celebrating on the 4th of July but a massively immoral action? It was certainly not legal for the the colonies to secede from England.

Sure, but those are averages. I'm 30-ish, and my hearing doesn't cut out until somewhere in the 21kHz range. When I was younger, it was even higher. One of my roommates in college had one of those anti-rodent high-frequency noise generators, we almost came to blows over it.

Defining God as supernatural and unprovable would lead the absurd situation that if God made Themselves self-evidently provable to everyone (say, with the whole trumpets and angels routine), then the alleged faithful would reject Him for not being their God, while He would only be believed by nonbelievers.

Sure, an Angel descending from the heavens would shatter our existing scientific understanding of the world, but that wouldn't make it intrinsically supernatural. It just would reveal a whole branch of knowledge that we didn't previously have any lines of inquiry into.

Yeah, it went from ~$10 / month to ~$30 a month to rent a relatively beefy VPS capable of doing the above (game servers being the most resource demanding of the lot). Still well within hobby money.

We were providing free services decades ago. Hosting a website, or a Minecraft server, or a VOIP server, or IRC, or a forum simply doesn't cost that much. Well within "some guy's hobby budget" type expenses.

Physics is a weird one to bring up, because even compared to other fields, it's one where breakthroughs are frequently the result of relatively singular genius. Newton, Faraday, Planck, Einstein, their discoveries were generally not incremental progress along existing lines of inquiry like most physics research is, they made pretty radical changes to our understanding of the world writ large.

In comparison, Carmack is grossly overhyped. He's like the Feynman of CS: A significant contributor to relatively young field, and a pretty influential communicator, but their contributions were moreso being the first to make a certain type of incremental progress than a paradigm shift.

If the skies errupted with the sound of trumpets and an angel descended to tell me to do something, my first thought would probably be that I'm having some sort of mental break, but if the person standing next me is seeing it, too, then I'll be the first one carving some commandments or whatever. There's a perfectly achievable standard of proof for you.

The page uses 'font-family: sans-serif'. They've already given up on any control over what the page looks like. They leave it up to the browser, which, IMO, more sites should do.

New Mexico has (pockets of) exceptionally well-educated population. 3 of the top 100 counties for PhDs per capita are in New Mexico (including #1, Los Alamos).

From what I've seen with Waymo, autonomous driving in relatively good conditions (light to medium rain, fog, or sunny) is a solved technical problem, even in small, winding streets. Snow is the next big hurdle, and they're actively working on that in Denver and Detroit.

They're being conservative with their rollout mostly because of civic issues. Most places do not have a legal framework for "what if your autonomous vehicle hits someone?" yet. Even if Waymos never were at fault for a collision with a person, you can always have cases like the one in Georgia back in October where a bicyclist wasn't looking where they were going and rammed into one. The shaky legal ground is a pretty big impediment right now, and that's in the US where we have much laxer laws about corporations killing people.

This guy isn't just the CEO (someone who "works for them"), it's a cofounder with 50% ownership. Personally, I avoid buying anything from the KKK bake sale.

We had a photolithography lab when I was at school. It's not that complicated to make a few npn transistors. The difficult part is doing it well.

They do not go to the same schools. The school system is controlled nigh-exclusively by the states, to rather infamously mixed results. That Northern Californian kid is getting a world-class education. The kid in Georgia is almost certainly not.

Meanwhile, the US is wildly more diverse at the local level than Europe is, which leads to its own significant cultural differences. Up in Northern California, about a quarter of people are of Asian descent, predominantly Indian and Chinese. Another quarter is Latino. Southern California is half Latino. Jump across the country to the Midwest, you've got a lot more people of German descent, in the South you've got Black people making up a significant portion of the population. What the US lacks in local history, it makes up for in cultural admixture: all those diverse backgrounds end up stewing together in unique ways across the country, producing all sorts of unique cultures. Leads to some fantastic fusion foods: Spam wasubi, breakfast burritos, American pizza, soul food, Chinese-American cuisine. Sure we don't our own thousand years of rich fucks inbreeding over funny hats, but the wide spectrum of cultures across across the US draw from the histories of everywhere on the globe.

Compare that with, say, Germany. Germany is 70% ethnically German. Most US states aren't even that 'White', never mind breaking that down by individual countries of origin.
