coryrc··on A message from President Kornbluth about funding and the talent pipeline
Our systems are highly undemocratic. A vote in Wyoming is at least an order-of-magnitude more impactful than one in California.

> all the incentives align towards pleasing extremists

Systems create the incentive! Changing the system changes the incentives and is the only way we can reduce extremism.

No. A language with checked arrays can never have a buffer overrun like C arrays can.

Some things are better. Game theory demonstrates this.

Learning calculus is table stakes.

While you're almost certainly wrong about "not learning calculus or chemistry better at MIT than in an unknown university", learning happens outside the classroom just as much as within it. Students at random Italian University don't have a connection to people doing the most advanced research in the world. At MIT, that person is there and the people they are mentoring. You can work with those people and learn things that won't be taught in classrooms for at least a decade. That isn't happening at Podunk U.

Our systems need to be MORE democratic!

First Pass The Post is democratic, but the worst way of it. In most districts, 40-49% of voters are disenfranchised by gerrymandering.

Mixed Member Proportional is far more representative. If you assume certain minority groups vote as a bloc, then you can't gerrymander them away like our current system does. The proportion of people not getting representation is capped by 1/number_of_reps.

The whole "republicans in Senate stop the government from doing anything" needs to end. Parliamentary systems means the legislative body and head of state agree to work together. Our system means deadlock most of the time.

Finally, "senior members" of the parties in both houses are the only ones who decide what bills can be voted on. That's not democratic. Every member should be able to bring at least some bills up for an up-or-down vote. Make them vote down "healthcare for veterans" instead of killing it in committee or amending it to add "only if you strip women of bodily autonomy".

coryrc··on New stainless steel can survive conditions for hydrogen production in seawater
Hydrogen is used as feedstock for many industrial processes, but also converting it to methanol should be the way to go for seasonal storage, but getting cost-effective hydrogen is the harder step.
coryrc··on New stainless steel can survive conditions for hydrogen production in seawater
I would say your question needs to be expanded to "Is this a valuable & efficient way to store energy which can be scaled to any location?". The pumped options aren't. Batteries are cost-effective for time-of-day shifting, but not long term. Electrolysis and gas tank storage can be built in any climate, any terrain. Then benefit from economies of scale while the others are stuck in niches.

It's an AND. The union is why administrations can't get rid of the problem employees.

In Seattle, the police are "quiet quitting" (traffic ticketing is down 8x over ~10 years ago) and literally committing fraud and getting away with it (an officer on his second time falsely applying over 24 hours of work in a day, just had to return the pay for that week. There's STILL not computerized time tracking...)

coryrc··on I want to live like Costco people
> What are you having trouble finding, out of curiosity?

Five employees couldn't find the macarons (I found them next to the raw chicken!?)

The snack bars are being moved around. Now some of the ones we buy are with the toothpaste!?

My wife asks me to pick up some sort of caffeine product. There's three spots they could be in she tells me to look. Sometimes that doesn't work either.

We're considering cancelling. We don't drive much and our vehicles are electric. Not a lot of extra money for their vacation packages.

That's why there's an article, with text beyond the headline.

Don't be obtuse. You can quit a boss and never see them again.

> simply stating "stayed in school" feels like an oversimplification of what was done here

> Am I misunderstanding something here?

"Stayed in school" is a clear, binary condition that's easily measured and has obvious benefits to everyone because everyone is at least a little educated.

If I ask you "is your house temperature livable?" and you say "the thermometer says 20", answered. You didn't say "well, I purchased and installed a heat pump and duct distribution system capable of forcing warmed air to be distributed to the remainder of the house, which keeps the temperature in a habitable range, then ensured power supply remains connected and kept it on" and say I didn't really explain the important part.

The "new" white Leviton is kinda nice. Or maybe I don't know what I'm missing!

Buying the panel box which is unchanged from the last 70 years and costs $50 less than a nicer new style, but also our houses are big enough the panel is nearly always in a mechanical room so who cares what it looks like.
coryrc··on To Restore an Island Paradise, Add Fungi
> A robot to pull 100 acres of white mustard and weeds is what?

Lets step back and say: could a bunch of humans with hand tools do this?

Yes, they could. (As opposed to, say, eradicating horsetail: if we can't even do it ourselves, then no, we definitely aren't getting a robot to do it).

One way could be the lasers-on-trailer approach, burn the undesirable plants so they're sufficiently uncompetitive. Another could have arms and cutters to reach down and sever the plant below the surface.

Either of the above could instead be a smaller autonomous robot working as part of a swarm day and night.

coryrc··on Waymo in Portland
Too many, but at least some are directly on vehicles. Transit (in the USA, on the West coast) is funded >90% by taxes on income, property, vehicle registration, fuel, etc not by the people using it.

Doesn't matter if there's only four people willing to ride on a given schedule.

> in your comment you're excluding road cost

Partially not, as gas taxes cover part of it. I think gas and diesel taxes should cover the full cost of roads, which would help. Still doesn't mean transit should be run so inefficiently.

Yes to the first half, for the most part.
coryrc··on Waymo says can't avoid bike lanes because riders want to be dropped off in them
In Washington State, they're required to follow most car rules when in a lane, but not all (i.e. all stop signs are yield for cyclists). They also have a set of rules allowing for sidewalk usage when mounted; when dismounted, they follow pedestrian rules (obviously).
coryrc··on 'Hairdryer used to trick weather sensor' to win Polymarket bet
I'll steelman it: previously there was no monetary gain to be made by messing with weather sensors. A market like this creates one, creating an externality on owners of weather sensors, on enforcers and courts to investigate and prosecute novel crimes. Administration of taxes on such markets to compensate all the disparate factions harmed by the externalities exceeds the amount which could be collected, so banning is the only proper solution.
coryrc··on Alberta startup sells no-tech tractors for half price
They get used in burst cycles -- like 10 days straight at harvest time, other times not started for months. Battery cost per kwh used is very low amortized over its full lifespan, but if you only use it to 1% of its capability your costs are now 100x higher.

Now, hang a high voltage wire down from a big-ass catenary, so you don't need batteries, and it'll be cheaper upfront and in use, but nobody does that because of 1. safety 2. if everybody did it the grid would need upgrades

coryrc··on In the UK, EVs are cheaper than petrol cars, thanks to Chinese competition
And not enough share on the people who built on a tinderbox which historically regularly (every few years) had fires go through.
coryrc··on Migrating from DigitalOcean to Hetzner
Exactly. I've never not bought something because the website was temporarily down. I've even bought from b&h photo!

Even if Amazon was down, if I was planning to buy, I'd wait. heck, I got a bunch of crap in my cart right now I haven't finished out.

Intentional downtime lets everyone plan around it, reduces costs by not needing N layers of marginal utility which are all fragile and prone to weird failures at times you don't intend.

coryrc··on Google broke its promise to me – now ICE has my data
I have one page with my full history of text messages, full transcription of all voice messages, contacts information connected with every number, and I can search everything. I can configure which of my phones ring.

And, possibly most importantly to me right now, my current phone has only a data connection and I make and receive calls using the Voice app. I think SIP eats too much battery and data and doesn't work well for wifi<->lte switching, but it's been a long time since I used it much.

coryrc··on How NASA built Artemis II’s fault-tolerant computer
That's a good one. I probably should have brought up variance though. These cache-less systems had none. Windows might just decide to index a bunch of stuff and trash your cache, and it runs slow for a bit while loading gigabytes of crap back into memory. When I flip my lightswitch, it's always (perceptibly) the same amount of time until the light comes on. Click a button on the screen? Uh...
coryrc··on How NASA built Artemis II’s fault-tolerant computer
Every single hardware subsystem adds lag. Double buffering adds a frame of lag; some do triple-buffering. USB adds ~8ms worse-case. LCD TVs add their own multi-frame lag-inducing processing, but even the ones that don't have to load the entire frame before any of it shows, which can be a substantial fraction of the time between frames.

Those old systems were "racing the beam", generating every pixel as it was being displayed. Minimum lag was microseconds. With LCDs you can't get under milliseconds. Luckily human visual perception isn't /that/ great so single-digit milliseconds could be as instantaneous, if you run at 100 Hz without double-buffering (is that even possible anymore!?) and use a low-latency keyboard (IIRC you can schedule more frequent USB frames at higher speeds) and only debounce on key release.

I misread you as saying all homes. You're right that anywhere that's sunny year round, a SFH can be self-sufficient for electricity with photovoltaic and batteries.
