I’ll check this out. The macOS photo library situation is really embarrassing. I actually migrated from Affinity to DxO Photolab (expensive!) a few years ago just for that.

It’s written in Swift and uses SwiftUI and UIKit and AppKit.

Seriously, what the hell are you talking about and why.

If LLMs reach a point of sufficiently high competence to the point that they're capable of producing usable software from vague, and sometimes contradictory instructions - the same software engineers have to regularly deal with, then at that point software will simply be an expectation of ability in any job.

I don’t understand how people can say this and then continue talking about software. So we’re saying machines can now casually do complex and cognitively demanding jobs like software development (or 90% of all white-collar jobs out there) and we’re NOT worried about the lynching mob going door to door and hanging IT people on lampposts? And I’m being serious, the impact this would have on societies would be unprecedented.

if in the future there's a prompt specific language, it would be committed. I dont think we've reached there yet, but i dont doubt this is on the path to the future

You mean, like a ... programming language? Honestly I can't tell these days what is satire and what isn't.

IMO delegation isn't abstraction.

I work at a certain level, like Ruby code. That's what I write, debug and maintain. I don't really care about the internals of the interpreter or about the source code of Linux, because these layers are taken care of, they're reliable and they're being developed by competent people. I [think I] know what Ruby code should look like in order to remain [reasonably] fast, maintainable and reliable, and it's my job to build a product out of that kind of code. If I keep writing code like that, I know for sure that I'll be able to keep building the product, because the layers underneath are deterministic. It's like the certificate chain of trust, but with "surely these people are not idiots". And that's simply not the case with LLMs.

Not only can the LLM be a massive idiot, but also an unpredictable one. I can try to warn it, steer it, police it or review as much as you ask me to, but ultimately you're asking me to delegate my job and my responsibilities to an intermediate whose reasoning I don't understand, who has no loyalty, no sense of pride, no sense of ethics, can't be taught and can't be fired.

Two 18650s hold about 22Wh of energy, more than two iPhones, and 20x more than what the parent comment is talking about.

Wider architectural guidelines, yes. "How a senior developer in this company would do it" — not so much.

My understanding is that this is still an unsolved problem. At some point you lose touch with the code and you start working with a mental model that’s subtly inaccurate. You just sort of hope that the people below have are competent and are building stuff that matches your mental model (that you’re communicating well!).

For me, the issue is that the model can explain what the code IS, not what it’s supposed to be or aspiring to be. The code doesn’t explain the original constraints (because it already fits within them) and it doesn’t show the tried and discarded approaches. It’s like rewriting a MIDI roll back into sheet music. Or better, it’s like the difference between being the author of an opera, and having read reviews of it.

Fable is better than most staff engineers at my FAANG.

That’s genuinely disturbing.

The very first image at the very top of the MultiAir article shows, prominently, a camshaft and the cams used to actuate the valves.

Fun thing about the sodium filled valves — these are also used in cars. The engine in my previous econobox, a 3-cylinder 1.0 TSI (EA211) uses them in the 81 kW variant.

I don’t think it’s pretty well established, there are cars that will happily stop and start the engine multiple times per minute, e.g. Toyota hybrids with their “HSD” drivetrain. It just requires some engineering.

You’re replying to a post that says that “explosion” doesn’t imply “detonation”.

Not exactly. You do want a deflagration and not a detonation, but "explosion" is more loosely defined and, depending on who you're talking to, a self-sustaining subsonic flame front and a sharp pressure spike are a perfectly valid explosion.

Note that that sentence is talking about the crankshaft bearings and their hydrodynamic lubrication, which is, well, elsewhere and separate from any cam rattle issues (including the cam phaser oil starvation that you might be referring to).

You might be misreading the animation. It's a direct injection engine, the thing that happens during the compression stroke is fuel injection. Ignition happens a few degrees before TDC, which is realistic.

Claude does that too. “That always confuses me” or “I usually realize”.

Not only do these imply that the thing has a personality and preference, but also continuity and a life outside the chat window.

I had to add an explicit instruction not to impersonate a human, it was just too weird for me.

That’s not what they said. The game does work without mods, but the economy is weirdly nonsensical (AFAIK you can push unnecessary amounts of cargo over long distances, and the game rewards you anyway) and I personally find it kind of pointless, compared to something like Transport Fever 2.

If anyone else is disappointed by the terrible AI slop article: It's about a fully liquid cooled data center design.

The usual way to cool servers is with air and heatsinks attached to the hot hardware, similar to how your desktop computer or laptop works. As the hardware gets denser and more powerful, you need bigger and bigger heatsinks and cooler air blown over them. At some point you can't make the heatsinks bigger because of space constraints, and you can't blow the air faster (because of noise and efficiency), so you need cooler air. That's when you start running chillers that evaporate water to cool your intake air. This is the huge water consumption that we'd like to avoid.

The next step is, obviously, liquid cooling. Again, this is similar to your fancy gaming desktop. You can dump a lot of heat to a liquid medium through a small heat exchanger inside, where you're space constrained, and you can run the liquid through a gigantic heat exchanger outside, despite the temp delta between your coolant and outside air being pretty small.

This article is about a system that's FULLY liquid cooled — CPUs, GPUs, memory, networking, the whole thing. That's the actual cool part (pun unintended). On top of that, their solution is optimized to be able to run the coolant quite warm — this obviously limits the heat flux at the hardware side, but it allows you to run the outside heat exchangers "dry", i.e. without wasting any water for its latent heat.

Rivian barely exists. Their market share is a rounding error. Škoda Enyaq (yes, the one model) is outselling Rivian, the entire company, by a factor of two.

I get it, Tesla has a bad omen for some who mingle deep in far left

That doesn’t sound like you get it at all.

It took me quite a while to figure out what the article is about. These don’t seem to exist over here.

I own a 3D pen and I use it to repair and tweak prints. Sometimes I use it to fill small cavities with material. The surrounding area usually doesn’t enjoy the heat, but PLA definitely can be injected to a degree. Maybe not to fill thin channels in the infill, but to fill a few strategically placed and shaped voids, yes.

It doesn’t have to be a large cavity in order to be useful. Imagine being able to reliably fill a hole that’s 5mm deep. Not amazing, but that could mean 25 layers. That’s 24 layers more than what we can fuse together now.

z-direction does not need to be more stable than the other directions so there is no need for long continuous strands anyway

I’m not sure I understand. In FDM printing, Z is the only direction where you currently CANNOT have long continuous strands, even if you need them. You always need to sacrifice one direction in which the part is going to suck.

For example, you can easily print an airplane wing with a beautiful, perfectly smooth and continuous airfoil, but you have to include a channel for something like a carbon fiber rod. Without it, the slightest bending force would instantly split the layers apart. Any other orientation will give you a rough surface with steps and a disgusting amount of supports. Being able to add a few strategically placed “columns” (i.e. members in the spanwise direction) could really help this particular usecase.

Do we have any numbers for this? Are those people “falling” for it or are they just choosing to buy the upgrades? I’ve paid for good (window!) seats on Ryanair flights, I’ve paid for luggage, I’ve bought a snack from the trolley. It would make sense to me that other people might be paying for other services.

I consider myself kind of sensitive to being forced to do stuff, but Ryanair just doesn't seem that bad. Of course, you get a million offers for things you probably don't need, but I genuinely don't feel like they're trying to scam me. It's like ad-supported Spotify or something. Annoying, but not actively trying to vacuum up my credit card.

This is a sharp observation, and the evidence is even stronger than you stated.
