All the modern CPUs will boost into high clockspeeds and voltage to get work done quicker but at considerably higher power draws per operation. On that side of the equation its clear that it uses more energy. The problem is the entire CPU package is on longer if you don't do that and this costs power too and so its a trade off between the two. Generally we consider there isn't much difference between them but I don't know about that having seen the insanity that was the 13th and 14th gen Intel's consuming 250W when 120W gets about 95% the performance I think its very likely moving down to power save and avoiding that level of boosting definitely saves small amounts of power.
That one's on my to-read list...

I am reworking the analysis of ECGs from an old contest, and I want help from an expert.

In 2000 the Computers in Cardiology challenge (CINC2000) provided ECGs from sleep studies of 70 patients and asked contestants to identify obstructive sleep apnea based on those ECGs. I was on the team that won.

Now I am reworking the problem for the second edition of a book (see https://www.fraserphysics.com/book.pdf), and I see great variety in those ECGs (see https://www.fraserphysics.com/all_ecgs.pdf). I suspect that some of that variety is due to lead placement, and some is due to pathology, but I'm not sure.

Is anyone here willing to help me out?
What I don't understand is why it took you 8 weeks to distinguish a timer from a transistor. That doesn't make your professor's reaction alright, I just find it puzzling.
The obtuseness and the soullessness of the user excited by this trick is what is most sad about this situation. "Look at me, I'm a cartoon!" speaks of the arrested development and some kind of a consciousness stunted by some autistic juvenescence prevalent in modern people. This pupa is really excited about living, I suppose.

Yes, now this I wholeheartedly agree. The system itself is not right and you can definitely credit MegaLag to drawing industry-wide attention to this issue.

People are hating the player when really the majority of the outrage should be pointed towards hating the game.
It's a thing! https://www.instagram.com/thatmallardguy/
I’ll add that features isn’t really a constructive way to think about the differences between C# and F#. C# has more ‘features’ than most other programming languages. One of the core features of F# is less features and churn. Also, I really appreciate the way F# maintainers agonize over how to maintain the language and keep it coherent. You don’t get the feel they’re chasing features at all.
This should be a reminder that more than you would expect, "the results didn't replicate" is really a statement of how difficult science is to do well.
I worked with Elixir for over five years without knowing anything about Erlang. I know Erlang now, but only because I was interested in learning it, not because I needed to do so to write Elixir code.
Very cool. Looks pretty cold there in fact. I wonder if that makes the cryogenic prop handling any more efficient.
The ideal setup for this would be faux channels on Plex but I haven't found anything that is quite right.

My ideal setup would be channels generated by shows in a random order like this. But I don't actually want my hard drives constantly spinning and Plex playing to nobody, which is what the channels seem to do. It would just track time and when you tune in, then it actually streams to you.

Mix in some commercials from 20+ years ago between shows optionally.
What I'm getting at is that you won't achieve anything by simulating a human brain. Which doesn't mean nobody will try, the World's Richest Man seems determined to send humans to Mars, which is equally futile, but just that it is definitely futile and here's why we know that.
Another one with Cahuzac: https://fr.wikipedia.org/wiki/Affaire_Cahuzac#:~:text=En%20m...

Don't remember the right whining about how ineligibility is undemocratic with this one (Cahuzac is left leaning)
I thought the same! I’m not sure if it would have to be a client or server side implementation though.

Might have to be both, like a new simulate TV mode.
somewhat unrelated to the topic, but I really liked this part of one of the sentences: “did not not only did not”. it does make sense in the sentence btw.
> And, unfortunately, doesn't even get the generic constraints right, as demonstrated with the int and bool examples.

If those constraints don't hold (like you say) it should manifest as runtime panic, no?

> What GP seems to expect is that sync.Pool() would always return a zeroed structure

Ah, well. You gots to be careful when Pooling addresses.

> But you completely forgot to do it, which questions what your code was for?

OK. If anyone expects zero values for pointers, then the New func should return nil (but this is almost always useless), or if one expects values to be zeroed-out, then Pool.Get/Put must zero it out. Thanks for the code review.
And yet, over the last year or two, people using ChatGPT to write their comments stand out like a sore thumb. The overall structure, the specific style of using em-dashes, semicolons, and colons...it's blindingly obvious.

If you just go back a couple months and read OP's comments, they sound very different from everything they've posted today: https://news.ycombinator.com/item?id=42734300

To be clear, I don't really care, I use ChatGPT all day every day, but just letting OP know it's often pretty obvious when you have it write for you.
EU is definitely behind. It's at least an entire generation (perhaps 1.5) behind.

ESA does have grants for funding reusable rocket development (ArianeGroup and Isar both got funding for that). Uhh... who knows how successful those programs will be.

To be fair to both Isar and RFA (which are both much more in the 2010s New Space mold), the equivalent rockets (Falcon 1, Electron, etc) weren't reusable either. EU firms are playing catch up, I think its fair that they take some amount of incremental steps through.

As people have generally noted, the market for stuff that Isar and RFA are building (1-2 ton to LEO) is actually really small. I think both companies are banking on building expertise and confidence and then trying to iterate relatively quickly to something Falcon 9 class with re-use.

The American competitors like Relativity and Stoke get to bootstrap off of all the work that SpaceX (especially) and Blue Origin (less so) have done to give a more credible path to immediate re-use.
For the same reason they don't focus on software quality, simplicity, or reliability - those things cost money and require good ideas and critical thinking. Too hard. Much easier to sell slickly-marketed garbage.
My physics professor told us once about a lab he had to do when he was a student himself, about measuring the adiabatic gas constant of air. The workload at that point was immense, so lots of students would just write a report and give the textbook answer—and be marked wrong.

It turned out the TA had sabotaged the experiment by putting alcohol in the bottom of the (dark glass) measurement bottle, so the measurement would be of the constant of “air with a fair amount of alcohol vapor in it”, which would give a different constant. And if you actually did the exercise, you'd get that “wrong” number, and that would be the only way to get the lab approved.

Hi there! I'm Nitin, a software engineer with a passion for AI/ML, computer vision, and automotive software.

I’ve spent some time at Bosch developing real-time ADAS applications and optimizing perception pipelines, and I'm now deep into research at NC State—exploring information bottlenecks in deep learning and contributing to open-source projects like SGLang. I've also led projects in robotic navigation using Visual SLAM and ROS, fueling my interest in autonomous systems. Lately, I've been diving into AI agents and exploring innovative applications across different domains.

I'm eager to collaborate on challenging projects in robotics, intelligent systems, or any cutting-edge tech. If you're working on something exciting in these areas, let's connect!

If that's Oracle's ZFS then it's not really comparable, it's essentially a very old closed fork. So on top of using a languishing outdated version you have another reliability problem (Oracle). It's a little bit like comparing OracleDB to MariaDB.

Most people use Open ZFS which is from the Illumos project, which was basically the escape hatch that the engineers who wrote ZFS used when Oracle tried to close source Solaris after the Sun acquisition. There are decades of improvements in all of the OSS versions that comprise Illumos (which Oracle has denied themselves by attempting to close source it, since they cannot feed off of downstream OSS code). i.e most of the people who wrote ZFS immediately left Oracle and worked on Open ZFS.

Open ZFS is for both FreeBSD and Linux, and is what most people are referring to when discussing ZFS. I've never used Oracle ZFS and never will.
> We will probably have to deal with this someday.

This is quite an extraordinary claim with no extraordinary evidence.

As said elsewhere in this thread we can at this moment not even simulate single atoms.

I see no reason to believe at all that we will ever be able to simulate a human brain.

Again there needs to be a distinction between the Observable Universe and the Universe. No Physicist thinks the actual Universe ends at the edge of the Observable section. Most estimates put the Actual Universe as ~250x larger than the Observable Universe, if it is finite at all.
Patroni will manage a PG cluster and auto fail over. I've heard of Stolon as well. If you're on k8s, there's a couple good operators that will handle this

This is a dishonest interpretation.
I don't think years of experience is a good measure of merit. If you believe they're worse at their jobs, you should demonstrate that in some other way.
The Mysterious Sinking of the Bayesian
The article directly mentions several.

> Teams across AWS that build some of its flagship products—from storage (e.g., Amazon S3, EBS), to databases (e.g., Amazon DynamoDB, MemoryDB, Aurora), to compute (e.g., EC2, IoT)—have been using P to reason about the correctness of their system designs.

Later it more specifically mentions these (I probably missed a few):

S3 index, S3 ShardStore, Firecracker VMM, Aurora DB engine commit protocol, The RSA implementation on Graviton2

I don't know the author, but I will note that my cardiologist got an Electrical Engineering degree before going to medical school and views it as a huge advantage when dealing with the heart.
There's a genuine question of whether fully simulating a brain will be enough. We have several hundred million neurons in our digestive system. What we eat, and the kind of bacteria that lives there influences our mood. Same with the rest of our body. Brains are part of a larger organism. What would it mean to just simulate the brain independent of a body? Our sensory organs play a role in processing the incoming sensory stimulus and then send that off to the brain.
Yeah, I haven't been following the specifics so much, but you can't just call someone a murderer over and over and expect to not get sued. I am still sorta surprised that Billy won though considering that he's essentially a public figure and has an already negative reputation. I suppose calling someone a murderer is a step too far though. Australian laws are probably a little different than America's too.
Oh this is interesting. Thanks!

> But that's only run when the pool needs to allocate more space. What GP seems to expect is that sync.Pool() would always return a zeroed structure, just as Golang allocation does.

Not quite that. Imagine I have a pool of buffers with a length and capacity, say when writing code to handle receiving data from the network.

When I put one of those buffers back, I would like the next user of that buffer to get it back emptied. The capacity should stay the same, but the length should be zero.

I think it’s reasonable to have a callback to do this. One, it doesn’t force every consumer of the pool to have to remember themselves; it’s now a guarantee of the system itself. Two, it’s not much work but it does prevent me from re-emptying freshly-allocated items (in this case reinitialzing is fast, but in some cases it may not be).

This also should be an optional callback since there are many cases where you don’t want any form of object reset.

Limiting the snowball effect of the wealthy getting wealthier generation after generation through no contribution of their own is considered a societal good. Whether it is can be debated, but Europe seems to be in a happier position regarding that than the US, at the moment. Why is it always the rugged individualists, the pull-yourself-up-by-your-bootstraps proponents who are in favour of receiving unearned money? It feels less like a considered philosophical viewpoint than naked greed.

(and, on a side note, where do you get that you can give unlimited tax-free money to your children in almost every country of the world? I checked the US, France, UK, Spain, Morocco, South Africa and Brazil, and all have limits after which tax apply. China and the Philippines don't, but neither do they have inheritance tax.)

It really doesn't sound like ChatGPT’s default voice, though it is pretty good at taking on different voices so in a sense you could say that about almost anything. It does use em-dashes, which people have recently started way over-indexing on as a ChatGPT tell, but lots of posters on HN have been using em-dashes for longer than ChatGPT has existed.

It does read like marketing material, though.
The context of what the application does matters. I'm extremely cautious when people hype up "download sizes", when such size is less than 1MB, because this is usually a sign of cosmetic obsession and/or disassociation from the real world value offered.

A 200-300kb "bloated" single page app which does the job of a 10MB "minimalistic" downloaded store app – is IMHO pretty incredible. It's doing the same work at nearly 1/50th the size, all else being similar (externally loaded images and stuff). Heck, even a 1MB page load size is still 1/10th smaller.

Sure, it can be argued that the browser does most of the heavylifting. The same can be said of Android or iOS too, definitely the OS offers _even more_ heavylifting than the browser.
As far as fluency goes, that’s not very impressive.

%w{Peter Julia Xi}.map{"Hello, #{it}"}.each{puts "#{it}! Enjoy your Ruby"}

That’s of course trivial examples. And while Ruby now have RBS and Sorbet, it’s yet another tradeoff compared to a syntax that has upfront static analysis as first class citizen in mind.

That is, each language will have its strong and weak points, but so far on "fluency" I’m not aware of anything that really beat Ruby far beyond as Ruby does compared to other mainstream programming languages.
I had discovered the windows net send command as a highschooler too. We mainly just messaged jokes back and forth. One student later decided to try the wildcard to send to everyone, just a simple "Hi". It went out over the entire district hitting multiple schools. I forget why, but no one knew who did it at first. But we had some software installed that let the admin/teacher remotely blank screens or lock the computer, etc. I remember they blanked his screen remotely and once he complained they knew it was him. Didn't get in too much trouble, but I still felt bad for teaching everyone about net send.

I recently thought about just using ASP.NET MVC with Razor pages for a quite simple app at work. But I'm already familiar with SPAs, so with that background I chose to "just use Vue as always (or Solid or Svelte, I like all three of them)" as SPAs have some advantages, e.g. separation of concerns, easier integration of libs like agGrid or eCharts.

Without that knowledge, I agree that good old SSR (MPA) is easier and more maintainable. And more robust.

I suppose that's where a nematode is interesting — it's maybe juuuust simple enough that a real nematode on a plate of agar (as described in the article) might be able to be simulated well enough that we could actually make useful, and even long-term predictions about it based on a mere model.

Not to say I'm fully convinced, but I can see the appeal.
I wonder if its because (1) theres no space left on the Med coast in Spain for this or (2) if a Spanish launch site does not offer enough angle for moderately inclined orbits because (3) they would still be dropping hardware on central Europe for nearly all common orbit profiles.
I understand what you mean re: Arch wiki (I'm a fan of it even though not an arch user) but I genuinely suggest you go over and read some of the FreeBSD Handbook. Just look through the ToC (itself a nice thing) and pick something.

It is a cohesive whole which can be read from start to finish (it is an actual book). This is also how the whole system feels as well (as others have commented). Things are integrated and coherent. Example: freebsd has its own libc[0], and the kernel and libc do feel (from old experience) like a consistent unit, so to speak.

So IMO in terms of system cohesiveness (and its documentation which is a marvel unto itself but also represents the thing it covers), it's on a whole other level.

[not even using FreeBSD for any servers right now[1], but I have deep respect and admiration for the project and its team]

[0] that's the thing, as others have commented, Linux is really two parts (GNU+Linux) whereas e.g. FreeBSD is for most intents and purposes "one" internally cohesive part.

Same here. I've had the same setup for decades: A "homelab" server on my LAN for internal hobby projects and a $5 VPS for anything that requires public access. On either of these, I just install the software I need through the OS's package manager. If I need a web server, I install it. If I need ssh, I install it. If I need nfs, I install it. I've never seen any reason to jump into containers or orchestration or any of that complex infrastructure. I know there are a lot of people very excited about adding all of that stuff into the mix, but I've never had a use case that prompted me to even consider it!
Show HN: Generate Anki Decks from YouTube Videos to Anki Converter
Hello!

I love anki and have been using it for years to learn mandarin, but I'm lazy and always struggled to get over the "motivation hump" to sit down and create a deck.

Recently I've been consuming a lot of AI content from youtube, and spent 3 days creating a deck for Andrej Karpathy's "Deep Dive into LLMs" video. This is impractical - so I built a little youtube to anki converter @ asimpleai.com

It's rough around the edges... but I would like it to eventually become something useful to community. Feedback and suggestions are welcome!
