It seems like you largely agree with the article - people shall own nothing and be happy. Perhaps the artificially induced supply crunch could go on indefinitely.
Also, I wonder how many of us, even here on HN, have the ability to spend that amount of money on computer for personal use. Frankly I wouldn't even know what to do with all the RAM - should I just ramdisk every program I use and every digital thing I made in the last five years?
Anyhow, I suppose for the folks who can't afford hardware (perhaps by design), one ought to own nothing and be happy.
People spend a lot more than that on a car they use less, especially if they're in tech.
The RAM choice was because I have never regretted buying more RAM - it's practically always a better trade than a slightly faster CPU - and 96GB DIMMs were at a sweet spot compared to 128GB DIMMs.
That, and the ability to have big LLMs in memory, for some local inference, even if it's slow mixed CPU/GPU inference, or paged on demand. And if not for big LLMs, then to keep models cached for quick swapping.
I bought a 4 year old car for significantly less than that. And I can get a computer that can do 99% of what your monster can do for like 10% of the price. And if I want LLM inference I can get that for like $20 a month or whatever.
I don't mean to judge, it's your money but to me it seems like an enormous waste. Just like spending $100k on a car when you can get one for $15k that does pretty much exactly the same job.
Sure. You're right, it is my money. And I pay even more for inference on top; I have OpenRouter credits, OpenAI subscription, Claude Max subscription.
It's not so easy to get nice second-hand hardware here in Switzerland, and my HEDT is nice and quiet, doesn't need to be rack-mounted, plugs straight into the wall. I keep it in the basement next to the internet router anyway.
The "sensible" choice is to rent. It's the same with cars; most people these days lease (about 50% of new cars in CH, which will be a majority if you compare it with auto loan and cash purchase).
I don't think leasing cars is sensible. Last time I checked, for cheaper cars mind you, I would essentially pay 60% of the sticker price over a few years and then not have a car at the end of it. Would be better to buy a new car and then sell it after the same time. But what's even better is to not buy a new car, let some other sucker take the huge value loss and then snatch it up at a 30-60% discount a few years later. Then you can sell it a few years after that for not much less than you paid for it. I've had mine a year and right now they're going for more than I paid.
I think leasing might be okayish if you find a really good deal, but it's really not much different than buying new which is just a shit deal no matter how you turn it. A 1-4 year old car is pretty much new anyway, I don't see any reason to buy brand new.
I've always went way over on RAM, for the most part. 32, 64, then 128GB of memory.
Never really used it all, usually only about 40%, but it's one of those better to have than not need, and better than selling and re-buying a larger memory machine (when it's something you can't upgrade, like a Mac or certain other laptops)
China has made for-profit extracurricular tutoring illegal since 2021. [1] Of course there can be under the table operations and discussion to be had about regionally biased gaokao difficulty, but I think it's worth recognizing gaokao being a real chance for upward class mobility, hence why it is so competitive.
Starting in 2020 when I was a new professor, I was contacted by a company that works with Chinese families to tutor their students directly. I would be paid $400 an hour to teach them online remotely.
Originally I thought it was because of COVID lockdowns and that may be part of it.
But the opportunities have continued since then. I stopped doing it as my career has become more involved but I still get solicitations from time to time, so it must be because of what you say.
It's also a bit unreasonable to launch live munitions that have some 90% probability of being intercepted by a given system on a good day, while intending for "just a warning"
When they launched the drone strikes on Israel, they gave Israel and the US warning time so they could be intercepted. The second time, they gave them much less warning time.
The Iranians have a long history of negotiating loudly via their actions, which anyone who's spent any reasonable amount of time studying Iran knows and has seen in action. They're really not a mystery, they're very transparent, we just don't like what they're saying.
It’s more like if David and Goliath are in a standoff
David takes a small rock and whips it at a sensitive spot on Goliath’s ankles that most people don’t know about (Diego Garcia)
David knows Goliath will probably dodge it, and most likely kick it away given it’s importance, but there’s a point being made by shooting: if it hits then that’s a win, but if gets knocked down it’s a warning that they know where they need to hit for it to hurt
There are many things that are valuable to people, but which they would rather not pay for. They include public goods and externalities, like infrastructure and education and a reasonable amount of military. It makes a lot of sense that people would rather enjoy art for free if they had the option, and since the majority of art experience can be easily duplicated and transmitted, why pay for it yourself? There is also another benefit of art stimulating further intellectual and creative development of a society, perhaps yielding second order benefits that are hard to quantify. Thus overall, it can make a lot of sense for government to pay for art as a society.
The escapement is "synchronous" in that the motion is controlled by the number of pulses applied to the motor over time rather than the duration/width of each pulse. The pulsetime constant is only to accommodate mechanical/analog differences with the driving circuitry, from what I understand. https://en.wikipedia.org/wiki/Lavet-type_stepping_motor
That's fascinating; the Lavet-type stepping motor acts as an escapement all on it's own by being a very simple stepper motor, so you don't end up needing a miniature version of a classic mechanical escapement, which is what I'd always imagined in my head when thinking about how cheap quartz wall clocks worked.
Ask me a question about a specific realistic problem (ie, not "how do I replicate this behavior of PGP", but rather "how do I solve this real-world problem") and I'll give an answer (or someone else will).
I think I described (though perhaps too briefly or not clearly enough) the very specific realistic problems?
I'm somewhat amused that every time this kind of discussion comes up, the answer is "you are holding it wrong". I have a feeling the world of knowledgeable crypto folks is somewhat detached from user reality.
If a single tool isn't possible, give me three tools. But if those three tools each require separate sets of keys with their own key management systems, I'm not sure if the user's problem is being addressed.
It's because the phone design needs the battery to help stabilize the voltage under load. As we know, digital devices can nearly instantaneously change the amount of current they consume and thus require layers of energy storage to accommodate the transient currents quickly. However, the changing current consumption doesn't just happen briefly. It sometimes continues to ramp for more than milliseconds (a glacial time frame for modern electronics). Thus generally every component in the power supply network of a design serves some stabilization and filtering role, including the batteries.
It appears that in this case, as the original battery aged, its internal apparent resistance (ESR) increased beyond the original design expectations, to a point where the phone won't work when plugged in to a charging cable because despite the charging cable most likely being able to deliver sufficient power at DC, it had too much impedance to supply it quickly enough. When current is demanded from a source that has too high impedance to supply it, the voltage drops. This will result in significant voltage ripple to the power supply of the digital circuits, which can cause logic to not function correctly.
Adding a large capacitor basically replaced the filtering and stabilization role of the original battery.
Interestingly people often intentionally remove capacitors for side channel measurements and glitching attacks.
Fascinating, thanks for explaining! I had assumed it was just that capacitors were easier to get hold of than batteries, and that the author was just putting up with a reduced "battery" life as a result. It makes sense to replace with capacitors if they're just using it for always-powered static applications -- probably with much lower fire risk to boot.
There are modular dot shaped led matrix blocks that are basically LEDs under a cast piece of resin that guides light. They're tillable and you can drive them with an FPGA and a smart shift register based constant current driver. They're generic so you can look around online.
However this is assuming your installation will be reasonably large. If it's too big, I recommend making your own array out of discrete LEDs. They sell LEDs with a built in milky diffuser that are suitable.
Also, I wonder how many of us, even here on HN, have the ability to spend that amount of money on computer for personal use. Frankly I wouldn't even know what to do with all the RAM - should I just ramdisk every program I use and every digital thing I made in the last five years?
Anyhow, I suppose for the folks who can't afford hardware (perhaps by design), one ought to own nothing and be happy.
