> Unfortunately, this is not possible in C++, so the user has to move explicitly (with std::move).

Honestly why not? A locally used variable sounds to be very much something the compiler can reason about. And a variable only declared in a loop, which is destroyed at the end of each iteration and only read from should be able to be optimized away. I don't know Rust, I mostly write C.

We need to talk about both of them, not neither

You want constant ideological battles to end, and the answer is... do nothing?

They have the megaphone. If you want to take it away, we have to talk to each other about it so they start marginalizing their posts and opinions. MAGA is the poster child for the Overton shift, it's not going back any amount without effort

You'll need to understand that <blatantly political actor does stupid thing> is a criticism of the actor's stupidity, not the political faction.

If it consistently happens more often for any given political faction, then it's still not an ideological statement, just a realization that not every political direction has an equal commitment to facts and reality.

So, mostly, I'd like the alt-stupids to not take over.

Even in a distributed database you want increasing (even if not monotonic) keys since the underlying b-tree or whatever will very likely behave badly for entirely random data.

UUIDv7 is very useful for these scenarios since

A: A hash or modulus of the key will be practically random due to the lower bits being random or pseudo-random (ie distributes well between nodes)

B: the first bits are sortable.. thus the underlying storage on each node won't go bananas.

Like I said

> It could still be false, but I somewhat doubt it is.

I wouldn't have felt bad if it did turn out to be wrong, I certainly left room open for doubt. But what I know about media outlets is they aren't often willing to put themselves in positions where they could get sued into oblivion.

There are obvious exceptions, Alex Jones, Glenn Beck, Candice Owens, but I think those exceptions have a level of insanity that powers their ability to make wild accusations without evidence.

> One is that pickups are a weirdly-politicized lifestyle choice in the US

Based on my personal experience traveling, there's a more practical reason for the political divide.

I spend a good portion of my life in rural parts of the US these days, where most of the residents are pretty conservative. But these are also parts of the country where I get nervous when I'm on 1/4 tank of gas. If you're routinely out in places where the nearest gas station might be > 50 miles away, you also see a dip in e-vehicles for very practical reasons.

When I'm at home in a city, it makes perfect sense to own an e-vehicle: typically I'm only driving a few miles a day, and the car spends most of it's time at my house or in a parking garage. When I'm out on business, and driving across hundreds of miles of barely inhabited land, I cannot imagine the stress of having an electric truck. It's not just about being 50 miles from a gas station, it's about the time it takes to charge on top of that.

In rural parts of the country, especially when you're out working, you can easily be putting on mileage combined with being far enough away from a charger that it just doesn't make sense to have an e-vehicle.

> none of them have succeeded in spamming the Bitcoin network with blocks they've mined

I'm not saying you're wrong, but I have no idea what you're getting at, because the sentence sounds kind of absurd. As a result, I'm not sure if it addresses your point, but just to throw it out there: Bitcoin and anti-spam are different applications of proof of work. Anti-spam has to strike a compromise between being cheap for the user (who is often on relatively low-powered mobile hardware), and yet annoying enough to deter the spammer. It's not unreasonable to believe that such a compromise does not exist.

> Bots may be better than humans at Captchas now, although I'm not certain of that, but they certainly weren't when Signal was designed.

Fair point, but again, even in 2014, an instant messenger with captchas would have much more friction than every other messenger. And captchas aren't just bad because they introduce enough friction to drive away pretty much everybody: they also make users feel like they're being treated as potential criminals.

> I don't see why invite codes would be a problem for mainstream use.

Can you elaborate? Invite codes blocking access to the service itself "like lobste.rs" mean that no one can use your service unless they've been transitively blessed by you. That's obviously going to limit its reach...

> Or opt for door three: Ignore how CA/B Forum’s relentless ratcheting burdens ops into forking browsers, hacking root stores, or splintering ecosystems with exploitable kludges (they won’t: they’ll go back to “this cert is invalid, proceed anyway?” for all internal users).

It does none of these. Putting more elbow grease into your ACME setup with existing, open source tools solves this for basically any use case where you control the server. If you're operating something from a vendor you may be screwed, but if I had a vote I'd vote that we shouldn't ossify public PKI forever to support the business models of vendors that don't like to update things (and refuse to provide an API to set the server certificate programmatically, which also solves this problem).

> Nothing screams “sound security” like 45-day cert churn for systems outside the public browser fray.

Yes, but unironically. If rotating certs is a once a year process and the guy who knew how to do it has since quit, how quickly is your org going to rotate those certs in the event of a compromise? Most likely some random service everyone forgot about will still be using the compromised certificate until it expires.

> And hey, remember back in the day when all the SMTP submission servers just blindly accepted any certificate they were handed because doing domain validation broke email… yeah

Everyone likes to meme on this, but TLS without verification is actually substantially stronger than nothing for server-to-server SMTP (though verification is even better). It's much easier to snoop on a TCP connection than it is to MITM it when you're communicating between two different datacenters (unlike a coffeeshop). And most mail is between major providers in practice, so they were able to negotiate how to establish trust amongst themselves and protect the vast majority of email from MITM too.

is there any good comparison of Hybrid vs EREV efficiency (when main battery is depleted), even with Atkinson cycle ICE for EREV? my understanding was that the main reason for all this complexity in Hybrids was due direct-to-wheel power transfer efficiency, while in EREV there's efficiency loss when converting ICE output to electric current...

This author writes in ESL better than 99% of the people I've worked with in an English-native country, including myself. It's fascinating to read just how much more emphasis good-quality written English seems to have in Kenya than it does here in Australia (at least in the public education system where I have experience). I suppose that it's understandable, given that it gates access to higher-level education opportunities.

I don't really understand the aversion some people have to the use of LLMs to generate or refine written communication. It seems trigger the "that's cheating!" outrage impulse.

i tried to see if it has any ties to the actual GOP national or any state parties and it's unclear. I'm guessing it's not affiliated and GOP is not trademarked.

I asked because both political parties have chapters at national, regional, state & local levels so "GOP job board" on the face wasn't clear which organization was running it. Some parties cover rural counties of just a few thousand people.

"More expensive to keep running" might depend on where you live. My wife and I both have EVs and we drive about 2000 miles/month. At just over $.06/kWh our EV charger tells us that we pay about $30/month for "fuel".

The first tire rotation on my car was free, and the next two were about $60 total. The first tire rotation on my wife's car was free. We're both going to need another rotation in a couple of months. Other that that, the original wipers on my car were squeaky and I replaced them for about $40. Oh! And I replaced the cabin air filters myself at the 7500-mile service intervals.

When we lived in a much bigger city, there were time-of-day rates and assistance with the cost of putting in a charger offered by the local for-profit utility. The kWh rate was just over 3X what we're paying now and even that is cheap compared to some regions.

Insurance doesn't seem cheap but we moved from Farmers to Amica and there are a bunch of discounts for having cars with lane departure warning, collision avoidance, etc.

I expect to replace the tires at 40,000 - 50,000 miles based on what other people report they get with their original tires. I do get sad little postcards from the dealer about having our cars serviced because there's no oil changes, the brakes should last forever because of regenerative braking, there's not a catalytic converter to steal, etc.

And that Sonos is terrible to its users.

I had a houseful of overpriced speakers, some only 3 years old when they decided they were too old to support in their rewritten app, or some lazy crap like that.

For GP; I use some cheapo (sub $50) "100W mini amps" from Amazon. They seem fine to me.

I actually think in practice the meaning has always been "things I dislike". Before AI you could see it applied to all kinds of things in media, WWE is slop, Soap Operas are slop, Genre Fiction is slop. It's almost exclusively a pejorative based on taste, intended to throw scorn on what other people enjoy. When a person uses it I stop listening, because essentially the speaker has stopped saying anything of value.

I might be biased because I hang out in the slate subreddit and have been pretty attentive to The product as a whole since they announced it this spring but I think they're on to something assuming they can figure out how to build out the service and parts network.

The vehicle itself may be a runaway sales success but if there's only or two locations in each major state where you can get it serviced, that runaway success will be extremely short-lived.

In theory the simplicity means that it shouldn't be difficult to partner with any independent shop... No complicated or proprietary software theoretically means that any shop with tools and a lift can do the work.

Time will tell, though. I remain optimistic and eagerly await delivery of my truck.

> Bigger the company the more power they have to dictate the purchasing price from producers and the cost for consumers.

That wasn't always true. The Robinson-Patman Act made it illegal to give preferential treatment to large retailers specifically in order to prevent what we're seeing with walmart and amazon today. The US just stopped enforcing the law (and also anti-trust laws that would have protected local/small businesses) so here we are. At any point the US could decide that enough is enough and fix the situation but we'd probably have to make it actually illegal for corporations to bribe government officials before it stands a chance of happening.

Apart from Sonos in general being awful[1][2], their web site seems to be pretty bad, too. Not only is there a modal "subscribe to our newsletter" box in that link, there's also a separate modal cookie warning which blocks the modal newsletter box. It's like frustrating users is core to their mission.

The idea that TikTok is somehow less corruptible than Facebook or Instagram is laughable as American investors were largest investors of ByteDance to begin with. If it was only about Israel, they can be pressured into censorship the same way Meta supposedly is*. The difference is that TikTok can also be pressured by China, where its parent company resides.

*What is more likely is that TikTok isn't actually more pro-Palestinian than Meta, but the demographics that use it actually are which affects the algorithm and user reports.

This was written based on working on several Postgres databases at different companies of “medium” size as a consultant, that had excessive IO and latency and used UUID v4 PKs/FKs. They’re definitely out there. We could transform the schema for some key tables as a demonstration with big int equivalents and show the IO latency reduction. With that said, the real world PK data type migration is costly but becomes a business decision of whether to do or not.

I sometimes wonder if there are people out there who just read too much Neuromancer, and they think they can construct their own Tessier-Ashpool orbital dynasty.

I suppose there are several other Oligarchs In Space stories and movies since then, but if the point of the space station is to host AI, that narrows it down a bit.

Or perhaps it's performative, designed to spook gullible politicians into changing laws to "keep" businesses that were never actually going to go somewhere else anyway.

Nostr doesn't even have the decoupling afforded by what we typically think of when we think of federated networks (email, activitypub, matrix). If you and another party aren't using the same relay, there is 0 way for you to interact. It assumes either you pre-agree on a relay (sticky defaults encouraging centralization) or shotgun messages to many relays (economies of scale encourgaing centralization). The protocol explicitly forbids relays from forwarding to each other.

Nostr is a very simple protocol that could have been invented in essence in 1995. There's a reason it wasn't invented until recently, because it's difficult to build robust protocols with good guarantees about discoverability and reliability with a foundation that is as limited as it is.

> companies will not prioritize serviceability unless mandated by law

Ford is “expected to take about $19.5 billion in charges, mainly tied to its electric-vehicle business” [1].

If serviceability was the problem, that sounds like a solid incentive to get it right.

My experience is that most forum style social media has been devoured into the reddit world, and furthermore that any attempt at making an offsite version of reddit or similar forum-like functionality is either locked down with rules that would make the Stasi blush or quickly converges on a new Stormfront forum.

The problem with reddit's panopticon moderation, with its ill defined, nebulously (and now AI) enforcement of sitewide policies, ends up repressing a negative behavior rather than refuting it, and, when people move to a similar off-reddit site, they are itching to start taking part in discourse they weren't allowed to before.

The end result is that people who are used to policing their own speech to avoid the panopticon rather than because it's the right thing to do eventually lose that moral code that was previously shaped by discourse and pushback from their peers rather than anonymous opaque moderation.

We may be talking about different things.

If your talk is about, say, heat engines, and you want to have an animated Carnot cycle or something, great! Do that! That sounds useful! (These days it would probably be implemented as a video, which is why my brain binned it as such, but it really could be done with PowerPoint alone.)

If you want to have your slide chug in from the right "like a locomotive" then have each item on the screen individually fade in "like puffs of steam" then once you're done the whole thing drifts to the top "like smoke" because "steam engines are heat engines", that is the crap I am telling people to get rid of.

It isn't clear that the law in question makes exceptions like you're making. Did you read somewhere that it does?

Also, people who work in politics are allowed to run for office, and people who run for office are allowed to work in politics, so what specifically do you see as a conflict of interest? Remember, the company claims this wasn't about politics, so your answer can't involve politics.

> Why do you need a truck?

To haul dirt. To haul junk out to the dump. Etc.

Do people load their Transits with piles of dirt and mulch? I doubt it.

I live in the US and have a small house in the city, and I haul stuff like this all the time.

Yes, you can rent a pickup truck as needed from U-Haul, but that gets old real quick.

Yes, I would love it if there was a nice small or mid-sized truck with an extended bed available, because most trucks are overkill for my use case.

But this idea that no normal person needs a pickup truck a dozen times a year is just weird.

South Asian (Indian) / White / East Asian ceo gap something like 3 / 2 / 0.5 per million pop in US. Chinese long recognized this ceiling, and more are returning to PRC because of it. More and more, PRC getting Chinese returnees that are credentialled 40yro stuck at manager / director level who see greener PRC grass leaving after accumulating industry knowledge / experience taking their entire network / ip / tacit knowledge with them. PRC use to pay a lot of recruit these folks, but we're at that point a lot of Chinese Americans from 80s-90s are in their 30s-40s, who know how high they can climb in US. Meanwhile PRC printing highend jobs that attract Chinese talent with comparable compensation, and a better title / social status.

The fact that 6 people replied to my comment in order to "correct me" on something that is less deadly than hunting accidents, is the most evidence I can offer for my point.

In the signal of things that are damaging society, negatively impacting individuals, police-brutality-self-investigation-no-harm-found is so far down in the noise floor, it should be about as worrying as people who live on busy street intersections not trimming back their hedges for safe driving visibility.

But somehow, here are 6 people deep in random HN comments telling me all about the importance of trimming hedges. Err, reforming police.

The problem with this whole argument is that you can easily reframe the definition of the activity to suit any specific agenda.

Going with the swimming analogy: If you’re attempting to cross a pool, you can just dead man’s float and eventually you’ll get there. If you’re attempting to cross it using crawl stroke you can do slow slowly and lazily. If your goal is to build Olympic tier swimming fitness, well then you need to pull exactly as hard as you need to to optimally build muscle / neural pathways / whatever.

By the way, overgripping is proven to boost effective strength. Next time you’re struggling for a last rep, try squeezing the bar harder.

My point isn’t that we shouldn’t burn ourselves out, it’s just that it’s very hard to know what the amount of energy an activity actually “requires” is

Paid certs are valid for 1-year from the $$ CAs. LE certs are only good for ~3-4 months before they have to be reissued. If there's no easy way to do an automated ACME setup to handle the renewal, being able to defer that for a year is worth the $20 or $70 for a wildcard.

If paid certs drop in max validity period, then yeah, zero reason to burn money for no reason.

This is very accurate to me. In the last few years I've been learning ukulele / guitar / bass / mandolin / banjo, and it took a LOT of time and practice before I could control my muscles well enough to use less effort. When you're starting you just don't have the necessary dexterity, and it's very easy as an expert to forget about those early days, especially if you learned very young.

I learned piano starting around age 6, and I vaguely remember the first few years were spent largely on learning to control my fingers, stretch to play larger chords (as a child with fairly small hands, I couldn't stretch my hand to play an octave until around age 10 or 11), and so forth. I was learning to do this at the same time I was learning to write cursive, or hold a paintbrush, use a kitchen knife, etc - all kinds of basic childhood learning stuff.

Learning a new skill as an adult is like going back to grade school or even infancy in some cases. You can tell a small child not to grip their pencil so tightly, but until you've practiced handwriting for several years, your fingers simply don't have the control necessary to avoid using a heavy grip.

"Use a lighter touch" is fantastic advice for an intermediate or advanced student but incredibly frustrating for a beginner. Over the course of several decades of playing keyboard in bands I picked up the bad habit of playing with more force than necessary, which started to cause me problems. I had to practice playing with a lighter touch and that was actually a big help.

I guess you’d call my Chrysler Pacifica an “EREV” then.

It’s honestly perfect for us. 32 miles on a charge, we barely touch the gas except for the winter when it’s so cold out we need the engine to warm us up. Any other time and the battery is all we need, and it charges overnight on a simple 110V wall outlet. Long trips are still possible, you just drive. We go through maybe 8 tanks of gas per year with our occasional long trips (compared to having to stop at a charging station for an hour, I’ll take it.)

What do you mean "all the way across the ocean". From where? The distance from Curaçao to the Dutch people is exactly zero.

What "right" are you talking about, is there an agency where we file a claim, and it issues us "rights"?

All people from all nations, tribes and states came from somewhere, sometimes even replacing the local population. Sometimes peacefully, like Anglo-Saxons pushed out local Britons in England, sometimes violently, like Normans invaded and conquered England.

Or like the rich and diverse American Indian history -- tribes came and went, sometimes replaced, pushed out, conquered or assimilated with previous peoples who lived there. Please define "right".
