hengheng··on How Tesla is proving doubters right on why its robotaxi service cannot scale
That was the moment the veil was lifted.

There's a model Y with The Sticker on it in my street, introduced years after he showed his colors like that. No, dear neighbor, when you bought that car, you knew.

If only.
hengheng··on Let me pay for Firefox
There is a sad parallel to Wikimedia Foundation, rooted in the same argument: We don't know the correct price. These entities are effectively monopolies with no competitors, and there is no public negotiation on what the annual budget of these entities should be.

So once they get away with nag screens on the world's biggest billboards, CEO pay is suddenly 'justified'.

But that illusion only works when there is zero oversight.

hengheng··on Bypassing Google's big anti-adblock update
You didn't really mention what aggravated you.
hengheng··on HDD Clicker generates HDD clicking sounds, based on HDD Led activity
I have a watercooled workstation (don't ask), and one day I made it spin up the pump when the chips heat up. I believe it goes from 17% pwm to 18% whenever any chip is more than 15°C warmer than the water. Changes nothing, and you wouldn't set it up like that.

But the immediate frequency change is enough for me to anticipate a delayed reaction. "Oh, computer is computing. Reach for coffee."

hengheng··on Repasting a MacBook
I was tempted to do that with my first-gen Intel MacBook because it just wouldn't run quiet when idle, that is until I discovered by how much I could undervolt that chip with a random tool that I could just download. I believe I went from 1.26V to 1.03V, or at least these are the numbers still etched into my brain.

Ratio of the squares of those numbers is 2/3, and so the laptop was certainly quiet without having to open it up. But I was surprised at Intel's product back then.

Okay I feel old now.

hengheng··on Being too ambitious is a clever form of self-sabotage
Don't just reward your child for being smart.

Reward them for listening, integrating, being nice towards others, relaxed, comfortable, flourishing, in their lane

hengheng··on YouTube No Translation
The problem isn't the the translation isn't done well enough, but rather its underhanded nature that tries to sell a translated website as a genuine discussion.
hengheng··on The German automotive industry wants to develop open-source software together
As always there is a difference between what course of action is widely agreed to make sense for everyone involved, and what course of action is in agreement with the structure of the corporation. The Audi/ Cariad disaster being just one example.

I'd like to see some insight on whether this has a realistic chance of being the winning bet within the companies involved. So far it sounds too obviously useful to win the politics game.

hengheng··on 3D printable 6" f/5 compact travel telescope model
Really depends on what material you're pushing.

PLA is not strong and doesn't like to warm up in the sun, Silk PLA (made to just look nice on the shelf) can even be brittle. But there are better materials.

PETG is entirely reasonable, I store my pots and pans on PETG hooks and they're not oversized. The superior 3d printers can print ABS which is above any and all doubt.

There are also specialized materials, such as carbon infused PETG, and there are engineering materials at 500€/kg with some interesting properties. But the gist is that PLA makes you go "this sucks, must be printed", and PETG makes you go "oh this is fine".

Then there are resin printers that selectively UV cure a liquid to polymerize it. Last I tried that sticky goo it was awfully brittle and borderline unusuable. I heard it improved, but that's why resin printing is not everyday parts but figurines.

hengheng··on Why JPEGs still rule the web (2024)
Normal people use jpeg. It's good enough, much like mpeg-2 was good enough for DVDs. Compatibility always beats storage efficiency.

Photography nerds will religiously store raw images that they then never touch. They're like compliance records.

hengheng··on Drone shows: Will they overtake firework displays?
We first had that discussion some 10 years ago. They're not taking the world by storm, we know that much.

They are a worse variant of the fireworks we know, but they're different enough to be something else. Cost and regulatory overhead has meant that we haven't fully explored what that could be. Drones work at a completely different speed, and with a different language. Much slower, much more docile. More female, if you will.

The same way that good firework is an art form, a good drone show is a whole choreography, and must be treated as such. It is neither a flashing firework, not a hovering dot matrix display.

Stuff is hard.

hengheng··on Google battling 'fox infestation' on roof of £1B London office
London has foxes, and they'll dig a hole where they can, and they are hard to catch?

Give me a break.

hengheng··on Stop over-thinking AI subscriptions
Or get a 3090 24 GB off eBay for 700€ and run mistral, devstral, qwen3 and others indefinitely.

I'm a big fan of two-tier systems where the 90% case is taken on by something cheap, and renting the premium tier. Works for cars, server hosting, dining ...

hengheng··on The ‘white-collar bloodbath’ is all part of the AI hype machine
I have a fusion reactor to sell to you.

Have you burn-in tested this method?
hengheng··on He has powered his house for 8 years using laptop batteries
Old laptop cells are going to need a lot more babysitting than a new LiFePO4 rackmount battery. Those generally do pretty well with the internal monitoring that they bring. Semiconductor fuse as overcurrent protection, passive balancing and monitoring of individual cell voltages seems to get you pretty far. Get your 48V or 51.2V battery in 5 kWh, 10 kWh or 15 kWh cell size from one of the Chinese outlets in dubious quality, or from real brand names like Pylontech. RS485 is usually present and there are kludgy home-assistant gateways, but they're not required for safety.

External monitoring is made by Victron, who initially did electrical solutions for boats. Their inverters are also very popular and pretty great.

Also, brick walls are kinda nice I have to admit, along with an exhaust for any fumes.

hengheng··on Is Astrophotography Without Tracking Possible? (2022)
I mean, there are also still radio amateurs out there, but the hobby has seriously lost appeal with the arrival of the internet. And the crowd that you're a part of is not growing either.
hengheng··on Is Astrophotography Without Tracking Possible? (2022)
Nowadays, most people who say astrophotography don't mean Deep Sky photography, hunting planets, nebula and galaxies. It's mostly the sky over a wide-angle landscape. "Astrophotography" happens at < 20mm.

Totally viable untracked. The classic 14mm prime has gone from f2.8 to f1.8 to f1.4, and sensors have become really good at high sensitivity for a 15 second exposure. Quite often, that's enough.

The hairy part is when it's not quite enough, and exposures have to be stacked. I have a crop sensor camera (canon 1.6x, so 40% area) with an f/2 lens that I like to step down further, and a good Starscape this way will take 10-40 exposures. I can stack those no problem, but it's trees on the horizon that are problematic. The ground stack and the sky stack have to clash, and a complex shaped border will always look photoshopped, because it is.

Old school Deep Sky is losing its appeal due to a) pictures being available online, meaning that you've already seen the better version of the same photo, and b) the images being sterile and without context, with no relation to the photographer's story. Milky Way in a national park says "I've been there!" in a way that a shot of the Whirlpool Galaxy just can't.

hengheng··on Building my own solar power system
Yeah, I wondered the same.

He mentioned that he refuses downsizing for ideological reasons, and I totally get that, but there's a certain amount of rightsizing that doesn't hurt in practical operation, and still let's you keep what feels like an awesome, big, complex model train setup in your garage.

Not all rust has to spin, almost no ports have to be 10GE, and a lot can be virtualized. Consumer CPUs have much lower idle than old xeons, and having less DIMMs with the same capacity also seems to pay off.

I'd be surprised if he couldn't cut that energy usage to 10% with a clear separation between hot and cold storage, and realistic expectations of bandwidth requirements.

But hey, I'm not judging. Solar power is great, and I don't mind waste as long as he can afford it and it makes him happy. Nobody drives the car they actually need either, and that is a much bigger problem.

hengheng··on Center for AI Safety's new spokesperson suggests „burning down labs"
Ah, so his recommended course of action is to "destroy a pipeline", and he will advocate for doing this and probably write a book called "how to destroy a pipeline" and he will absolutely not destroy a pipeline.

I've seen this before haven't I.

hengheng··on Don't guess my language
Leads to foreign-language posts on English-speaking small subreddits as well. I see plenty of Portugese, Spanish, Italian and German in communities that barely have enough traffic to debate in a single language.

But nobody pays to get answers, so it's alright.

hengheng··on AI Won't Kill Junior Devs – But Your Hiring Strategy Might
Or because bad légal documents become obvious immediately, while bad code has a 2-3 year incubation period.
hengheng··on Crypto has become the ultimate swamp asset
I am still wondering what money it was that predominantly went into crypto. Lots of retail investors lucked out between Tesla stock and BTC, but that can't account for all of it. I suspect a lot of shady money coming in from outside the US that raised the water level. Yet people talk about it like it's a co-op pension fund.

National bailouts going into an international fund are going to be a global power readjustment. Fun times.

My personal guess for an inflection point is civil unrest. Doge are already tightening the belts for the lower class. Nobody has really figured out how far they can take it. Police has been arming itself for the last decade or two, that started way before Trump, and they have been ready to thwart any uprising. But I am wondering if something is going to happen regardless. Civil war is only a bad idea as long as there are other options.

hengheng··on Crypto has become the ultimate swamp asset
Hence 'mid-term'. Lots of new money taking refuge there, but it won't be for long. Harder and harder to be on the winning side in this overall.
hengheng··on Crypto has become the ultimate swamp asset
What I'm always missing with these takes is the "what if" component. Nobody really dares to paint the whole picture in articles like this. Authors seem to go as far as to find the moral infraction, and then stop. But that doesn't do what is happening justice.

No, crypto does not need regulation. Law-based order needs crypto regulation. That's a big difference already. But we can go further than that. What if we don't get crypto regulation, what happens to law-based order exactly?

Trump is not the kind of guy to build businesses and create wealth. He more like kinda goes through them. He's not the guy to invest, he's the guy to cash out. Right now, he's cashing out of the US economy. Lots of real value is there for him to extract that is completely unprotected.

Trump is right. All those assets exist, and he can take them, destroy them, and liquidate them. He has that power. He is permitted. It is a programme, and his execution is successful. There's no point saying "but he can't do that, it would be unethical". Sure it's unethical, dumb, and nonsensical, but at face value, he can do all of that. No point in saying "but he can't do that, America would never be the same". That argument is reactionary, of course everything was going to change anyways.

So, let's face it. A president that is not going to miss his chance to join the true billionaires club (10+ b), a ruling class of industry leaders like it existed 120 years ago. Whether he stays president doesn't even matter. Government programmes are going down the drain, America's influence in the world deteriorates, trade volume breaking down, a less smart military will have to deal with more conflicts.

The only question in that turmoil is going to be what constitues a winner. Right now, everybody is buying crypto like lottery tickets, and it becomes self-fulfilling. Mid-term it might be Florida real estate. Long term? Who knows.

I'd actually like for somebody to really paint this picture and fill in the details. Stopping at the first inflection point that is somewhat scary is unproductive, we've been reading those takes for a year now.

hengheng··on The Awful German Language (1880)
Orwell said it better than I could, naturally. My point isn't that the professions can be traced back to origins in other languages. Nor do I mind a lingua franca for a scientific discipline. My gripe is that jargon, colloquial use and even common parlance haven't evolved away from it.

There could have been a movement away from old inherited terms. But there wasn't. And I have no better idea as to why than classism.

(German has a word for that! Jägerlatein, "hunter's latin", as a term for blowing up terminology to keep away the working population and restrict the game to the upper classes that are better educated, and frankly have a lot of time for that BS.)

I don't understand what argument you're trying to make, but I'm almost certain you did not understand mine either.
