zdragnar··on Scaling Git at OpenAI
Every bit of code is more context getting soaked up in future agent runs. More context used = worse output. More tests need to be written, then fixed, using up more compute, time and context without adding value compared to a more thoughtful, efficient implementation.
zdragnar··on Bidirectional charging during grid outages
In a conversation about whether or not battery backup is useful when the power is out, being safe and alive are foregone conclusions.

What's with all the moving of goal posts?

> The desire to operate a massive AC just after a natural disaster is just unhinged

The humidity after a hurricane is a great way to get mold problems in your walls. It is a major health hazard, and once it sets in you have a very disruptive and expensive remediation effort. Keeping the AC and central dehumidifier (assuming newer construction) running is pretty much the only way to prevent it.

The only thing unhinged here is your response.

Mold is the issue. Once it starts growing in the walls, remediation is extremely disruptive and expensive. Not fixing it is a massive health hazard.
zdragnar··on Anthropic may not secure investment-grade rating after IPO, Blackstone says
MAD / MAC assumes everyone has the same leverage on each other- that they are all as heavily invested in capital.

Where it falls apart is when you get companies that take open models, rent compute and sell tokens at a profit, without heavy investment into research or training. They spend way less, and if they can keep distilling the frontier models, they can produce reasonable products without the massive losses of subscription plans. In your example, DeepSeek et al aren't nearly so vulnerable. There's nothing mutually assured.

It is much more of a classic race to the bottom. Every new frontier model shifts the goal posts a bit, but eventually the house of cards will crumble - or at least, that's what the market seems to be thinking will happen.

> If you're just looking at caffeine intake you'd be better off switching from coffee to energy drinks

This is less true now than it used to be. I'm somewhat sensitive to caffeine and always look on the can to see how much is in it, and 150 is on the low side of most of the options available now-. 200 to 300 seems to be a lot more common among the brands that are newer than when monster and Rockstar first came out.

zdragnar··on Just Noting That Your Candy Corn Is Made of Bug Secretions
Quite a few candies still use it, including I think jelly beans, gums and chocolates. Candy corn is far from the standout here.
zdragnar··on Just Noting That Your Candy Corn Is Made of Bug Secretions
https://en.wikipedia.org/wiki/Candy_corn

The history section says it all. There was a fad of agriculture related candies targeted at rural customers. Jelly beans, squash shapes and so on.

Don't forget we also have circus Peanuts, gummy worms, candy ribbons, etc. Many candies have some sort of shape and design to look like non-candy things just for the novelty.

zdragnar··on Show HN: Auto Dismiss Mac OS "Allow <app> to find devices on local networks?"
BlackBerry supported incredibly fine grained permissions way back in the day, and even that wasn't sophisticated enough to support OP's use case.

I don't really even care what OP's good intentions are, because the minute the app is sold, those good intentions are out the window. I use very few apps because I assume they are always going to potentially be adversarial to my interests.

The system warning is correct and should not be subject to the developer promising free candy to gullible users.

zdragnar··on DoorDash to acquire Instacart
If you're working hourly from home and it saves you 30 minutes, or sick and can't leave the house, or the baby is napping and you don't want to wake her up, etc etc, it's more than paid for itself.

That's not to say it is worth it as an axiomatic rule, but it's something some people will choose from among the options available to them, which may be many or few, as dictated by their circumstances.

That's every single winter where I live in the US. We don't have a word for it like the Germans do, though, we just call it January.

How else will we convince everyone they have to live in a tiny box in a mega city without eliminating remote work?
zdragnar··on Anthropic S-1
Because the AI company CEO was telling everyone who would listen that his product might end humanity if the government didn't regulate his industry to kill off his competitors.
zdragnar··on America has lost 200k of jobs in media, film and the arts. How much is AI?
Either I missed or was added in an edit the bit about having roommates. That's definitely absurd. I was paying that amount for an entire house in a nice suburb maybe 8 or 9 years ago. Even with only one roommate paying the same amount, they are together paying way more than my mortgage for a house in the country with 5 acres of land and waterfront along one entire side.

I imagine they're in a high cost of living area, where tons of other people want to live. If that's the case, it probably shouldn't be any surprise that in a supply restricted market, the prices are also very high.

zdragnar··on America has lost 200k of jobs in media, film and the arts. How much is AI?
Assuming they work full time, that is pretty average. The old "30%" rule is that you should spend no more than 30% of your pre-tax wages on rent. Your friend is spending just over a quarter post-taxes.
zdragnar··on How close can pure functional programming get to C?
I don't know about roc specifically, but the best projects often come out of something someone built for a particular need. The open source / public version will often need work to strip out stuff specific to the original project, as well as refinement to make it more suitable for generic public consumption, such as adding support for edge cases, features that the original project didn't need but others likely will, support for multiple platforms for deployment, etc.
zdragnar··on Every AI model has the same "controversial" take on humans
Science fiction and think pieces aren't documentation, they are whimsy. Science fiction in particular is intentionally dramatic for the purposes of entertainment.

AI definitely shouldn't be informing its option of humanity or machines from it, aside from the propensity for science fiction writers to enjoy moralizing and anti capitalism sentiments.

zdragnar··on Amazon identifies Oct 17 PHP2Shell exploitation prior to public disclosure
> in general a proxy can protect you from more. It's strictly additive security, right

No, the proxy itself may have memory vulnerabilities that could give attackers remote code execution capabilities.

zdragnar··on PHP2Shell: AI uncovers critical RCE in PHP
AI writing the code doesn't make it safer. It is prone to making all the same mistakes humans do.

AI reviewing the code does help, though.

zdragnar··on Sixteen years after Deepwater Horizon, deep sea life shows few signs of recovery
The stock price fell by 50ish percent, and they've spent 16 years recovering.
zdragnar··on Apple routed a graphite pipe through the iPhone Duo's hinge to dissipate heat
I hear this a lot, but I have personally had terrible luck with Apple hardware. The most notable was the butterfly keyboard, but thermal issues were a fairly notable problem on several bits of kit as well.

Mind you, I've not owned any apple hardware in probably 5 or 7 years, but that's just been my luck when I did.

zdragnar··on New 'Super Ice' 10 Times Stronger, Bringing It Close to the Strength of Concrete
Concrete's not strong enough to be used as a bullet either- you'd need something roughly the size of a shotgun slug. If you're going that big, you aren't going for subtle.
zdragnar··on Tesla Roadster
It isn't being sold to the public. Of the three versions, the one that is "road ready" doesn't have the gimmicky thrusters. The one that is displayed is available by invite only, and even if you have a quarter of a million to reserve the racing model, you aren't likely to get a license plate for use on public roads.
zdragnar··on Show HN: Unfenced – Land for sale that borders public land
The OP mentioned having fences to keep their dogs in the yard. It depends a bit on the dog that they have, but I wouldn't trust untreated wood, using cheap wire mesh, without post holes, to keep dogs in a yard.

I also wouldn't expect the fence to hold up well if the yard had anything that would attract deer or bears.

zdragnar··on Show HN: Unfenced – Land for sale that borders public land
Fences are expensive. Firewood really isn't unless you're silly enough to spend money on the guys who come out and stack it for you for $600 a full cord. Awhile back I was getting 13 loggers cords for $1000, delivered, with the only caveat I had to cut and split and stack it myself. Upshot: I got to cancel my gym membership for the summer because that's a lot of work.
zdragnar··on Worlds More Habitable Than Earth? They're Out There
I'm reminded of the joke that the most dangerous thing in the ocean is all the water.

We don't have fuel sources that can run long enough for the trip, and deep space won't have enough solar radiation. We would need reliable mining spots along the way to replace metals made brittle by exposure or punctured by micro asteroids.

Even travelling at 1% the speed of light, stray hydrogen atoms become a problem. Not counting acceleration or deceleration time, that would be over 400 years just to get to the nearest star, let alone one with a habitable planet.

zdragnar··on Sorry we made you grind LeetCode
I don't think I lost my humanity by asking people to demonstrate their skills and then ranking them by preference to be hired. If I did, I've done a wonderful job of hiding it from everyone around me and myself as well.
zdragnar··on Hackers activate automatic defrosting in supermarket fridges across Europe
I can see how a subscription model would be appealing if it was in lieu of outright buying expensive equipment. Operating expenses for some machines are cheap but the machines are expensive enough that the tests themselves are expensive to pay off the machine.

Of course, the reality is more likely that the hospital still has to buy things and the subscription is a net loss on top of that so patients (or the people paying for the care) are screwed twice.

zdragnar··on Sorry we made you grind LeetCode
I wouldn't go that far. My last job had someone apply that blatantly lied on their resume. Had we just hired on vibes or a trial basis, it would have been awful for what was then a tiny business with a very narrow runway.
zdragnar··on A city-building game in which the city would prefer you didn't
Any simplification hides real problems and takes away from the point. Even your desire for simple choices and immediate reactions elides the fact that not every policy decision has visible short term effects. Some are only visibly beneficial or harmful in the long run, and may not end up that way depending on other decisions.
