> That's why when you meet someone who thinks like you the depth of conversation and thinking you can achieve together is vast and also incredibly liberating! Your no longer limited by words in same way.

Hmm.... I have to say, while I like the idea of being unlimited by words - the state of 'purer communion' is one I have frequently sought - I think it is far more likely that what is going on is that you mind is projecting 'likeness'. Both people in the conversation imagine that the other 'gets it' - a delusory and false assumption. After all, no one knows what goes on in another's mind - we simply don't have access.

I think talking is our means of 'ideas exchange', and that the greatest connections comes after lots of conversations, where one can (rightly) assume a shared understanding because one knows the terms are more-or-less lined up.

Language is an unavoidable throttling valve to me. And additionally, it's not the brain that's actually registering value/meaning either for me. You can call it the subconscious if you like, but I prefer 'soul' as that sense of oneself that is always there, has innate knowing, etc. Which is to say, there really is no way to express the depth of experience to another. But this is fine.

Regulation is not a problem, and even the construction costs are not terrible. We can take the Rooppur NPP as a base, it produces reliable energy at 6-7 cents per kWh. The reason for cost overruns is simply because NPPs are one-off products, the Western countries don't have a pipeline for NPP production.

For comparison, utility-scale solar with 16 hours of storage is 21 cents: https://www.utilitydive.com/news/higher-renewable-energy-cos...

Just raw solar without storage can be as low as 2-3 cents per kWh.

It would be against whomever is in possession of the stolen wealth, which will not likely be his estate. And yes, this should be a priority of any platform for rebuilding our country. Justice needs to be served. And by the time we're finally rid of these America-last fuckers, people still supporting the Trumps are going to be as rare as people still supporting the Iraq War.

I’m aphantasic with no mental imagery at all so my inner experience could not be more different: it’s strange to explain, but I experience “unvocalized” language, which means the words are sort of just there without “hearing” them in my head—-I don’t have inner sound at all either and so the words don’t have an accent, for example. My thought moves at a speed much faster than speaking and I can read fast with high comprehension—-but it takes me incredible effort to remember the color of someone’s eyes, for example. I more or less skip descriptions in novels and prefer to read philosophy.

I’ve always found it interesting that in programming communities the two extremes of aphantasic and hyperphantasic seem to both be very overrepresented.

> CPS has book keeping related to nested structures whereas SSA has the dominator tree.

CPS compilers have to do a lot of work to get rid of pessimization due to unnecessary closures. Inlining, contification, and lambda lifting are some of the things they have to do. IIUC SSA compilers don't have to do that, which is their main advantage (i.e., they are naturally faster).

> To assert that the way problems were solved in 1970 obviously has dramatic lessons for how to solve them in 2025 seems to me to completely miss what we're actually doing with computers.

True they might not all be "dramatic lessons" for us, but to ignore them and assume that they hold no lessons for us is also a tragic waste of resources and hard-won knowledge.

As I understood the responses, the benefit comes from making better use of the embedding space. BPE tokenization is basically like a fixed lookup table, whereas when you form "image tokens" you just throw each 16x16 patch into a neural-net and (handwave) out comes your embedding. From that, it should be fairly intuitive that since current text tokenization embedding vectors won't even form a subspace (it can only just be ~$VOCAB_SIZE points), image tokens have the capacity to be more information dense. And you might hope that the neural network can somehow make use of that extra capacity, as you're not encoding one subword at a time.

I think working on that kind of system would be actively harmful for most programmers. It would give them a totally unbalanced intuition for what the appropriate tradeoff between memory consumption and other attributes (maintainability, defect rate, ...) is. If anything, programmers should learn on the kind of machine that will be typical for most of their career - which probably means starting with a giant supercomputing cluster to match what's going to be in everyone's pocket in 20 years' time.

The bro grifters are going to bro grift because it gets them views and merch sales. Trump won't live that long: age, appearance, bad health habits, and obesity... and talk about not getting into heaven and display of extra NGAF by pardoning real pieces of work in a fury like he's already on his way out of office.

I could not disagree with you more.

It would be easy for me to agree with you. I hold a graduate degree in computer science and I’m named for my contributions proofreading/correcting a graduate text about algorithms in computability theory.

I love abstraction and algorithms and pure theory, but this whole “computer science is a branch of mathematics, nothing more” idea has always struck me as ridiculous. Are you willing to throw out all of the study of operating systems, networking, embedded systems, security (hardware and software), a good chunk of AI, programming languages, UI/UX/human computer interaction, graphics, just to draw a line around algorithms and Turing Machines and say this is all there is to computer science?

Rich people don't have to leave a state to use tax avoidance strategies. I live in Washington state. The recent state tax increases have reduced total state tax revenue. That's the point of the Laffer curve, tax rate increases result in less tax revenue. Now exactly the shape of the curve, that's hard to say. But you are obviously past the maximum when a rate increase reduces tax revenue.

PS The last several CA (I used to live there) tax increases resulted in decreased tax revenue too.

Speed of light is a constant and law only in the 5% of the Universe that's made of Matter and Energy.

Light is energy, it is a form of electromagnetic radiation, that travels in waves and consists of particles called photons. While photons do not have mass, they carry energy and momentum, which allows them to interact with matter.

But remaining 95% of the Universe is made of Dark Matter and Dark Energy, so if aliens are made of dark matter and use dark energy technology, their laws of physics may be different, and they could be capable of interstellar travel because they may not be limited by light's speed. Their dark matter and dark energy based technology may be incomprehensible or even irreproducible by us humans.

Scientists are still not sure what Dark Matter and Dark Energy are, so 95% of the Universe is still a big question mark to us all.

Are you trying to build AI applications or research AI itself? Completely different paths.

If it's the former - skip the math and start calling APIs. OpenAI, Anthropic, or open-source models via Replicate. Spend a week building something real: add a chatbot to your product, build a document Q&A system, whatever solves an actual problem.

The deep learning theory? You can learn that later if you actually need to fine-tune models or optimize inference. Most developers never do. Don't let the AI hype convince you that you need a PhD to ship useful AI features.

This article introduces OpenAI’s latest Sora 2 video generation model, which is now publicly available for testing on Microsoft Azure. For the first time, anyone can generate Hollywood-quality videos from text, opening up new possibilities for creators. The article explores the profound impact of generative AI on creativity, content credibility, the authenticity of memories, and the film industry, raising four key questions: How will content ecosystems change? What legal and practical challenges will AI video pose for memory and evidence? How will creators and industries be affected? And what urgent needs exist for safety and regulation?

The author also provides practical advice for creators and users on navigating the emerging “synthetic content era,” emphasizing the heightened value of authenticity and independent perspectives. The closing remarks highlight this as a turning point: the capability to manufacture reality is now widely accessible, and the choices society makes will determine the real impact of the technology.

LFP does have a lot more cycles in them by the nature of the chemistry. However EV grade NMC aren’t terrible either.

Depth of discharge and charge rate affect LFP specifically in such a way that if you keep them a good margin above cutoff voltage, relatively cool (60C and under, and do 1C and lower charging you can get 10,000 cycles per their data sheets. The same sheets will also list lower cycle counts for harder use that lines up with the standards used for earlier cells. Basically I think we’ll find a lot of gently to moderately used hardware will last a long time.

Whatever a believable use case looks like will probably end up on those data sheets and it wouldn’t surprise me if we see 15,000 and 20,000 cycles advertised for cells intended in low charge and discharge use cases (probably not cars but maybe home energy storage).

My Taycan has an ongoing battery issue relating to LG Pouch cells but its construction rather than composition that is the culprit. The same compositions from LG in prismatic and cylindrical models, the only models they sell now, so far haven’t been a mess for car makers.

While no one will deny you (or I guess your system) the immense satisfaction of 100x improvement on a given step, I think it would be helpful to note the frequency of this rebalancing step, and to contextualize your result in terms of the runtime (or throughput) of the workload(s) you were using to evaluate.

e: also comparison a fixed (nothing faster than 0!) and random policy might be informative if your intent is to publish this as improvement for the object problem, not just a demonstration of ARDS.

>the internet is breaking, hard.

I dont see that this is the case, its just more people want services over the internet from the same 3 places that break irregularly.

Internet infrastructure is as far as I can tell, getting better all the time.

The last big BGP bug had 1/10th the comments of the AWS one. And had much less scary naming (ooooh routing instability)

https://news.ycombinator.com/item?id=44105796

>The internet was born out of the need for Distributed networks during the cold war - to reduce central points of failure - a hedging mechanism if you will.

Instead of arguing about the need that birthed the internet, I will simply say that the internet still works in the same largely distributed fashion. Maybe you mean Web instead of Internet?

The issue here is that "Internet" isnt the same as "Things you might access on the Internet". The Internet held up great during this adventure. As far as I can tell it was returning 404's and 502's without incident. The distributed networks were networking distributedly. If you wanted to send and received packets with any internet joined human in a way that didnt rely on some AWS hosted application, that was still very possible.

>A simple mistake in on one deployment could bring banking, shopping and travel to a halt globally.

Yeah but for how long and for how many people? The last 20 years have been a burn in test for a lot of big industries on crappy infrastructure. It looks like near everyone has been dragged kicking and screaming into the future.

I mean the entire shipping industry got done over the last decade.

>Personally, I think the cloud metaphor has overstretched and has long burst.

It was never very useful.

>For well established/growth businesses and gov, you better become self-reliant and tech independent

For these businesses, they just go out and get themselves some region/vendor redundancy. Lots of applications fell over during this outage, but lots of teams are also getting internal praise for designing their systems robustly and avoiding its fallout.

>There's no shortage of affordable tech, know-how or workforce.

Yes, and these people often know how to design cloud infrastructure to avoid these issues, or are smart enough to warn people that if their region or its dependencies fail without redundancy, they are taking a nose dive. Businesses will make business decisions and review those decisions after getting publicly burnt.

Cryptography is all math, networking is largely math and algorithms (IMO yes this should really be replaced with information theory. Just understanding Shannons paper would have been more valuable than learning about how routers work), AI is mostly statistics (And AI as a whole Id argue is the essence of computer science), graphics is largely math and algorithms.

Yes I very much think a computer science degree should be as close to the foundation of theory as possible. And still learning Jenkins and kuberenetes or even a general course on how effectively push code is still far from the things you listed.

Theres so much computer science that isnt even covered that id include before including courses on CI/CD

> A normal person according to Christianity is closer to having two natures in the way you describe, because their body is mortal while their soul isn't.

AH, THERE'S YOUR PROBLEM! Cartesian dualism isn't the best lens to view human nature through and it makes talking about Christ's nature harder than it needs to be. The human person is a being whose nature is body+soul. The separation of the soul and the body at death is an evil brought about by sin. Put another way, death is injurious to human beings, not natural to them. (See https://www.newadvent.org/summa/3164.htm#article1).

Jesus is fully man. His human nature is body+soul. His human soul is immortal, as all human souls are. Unlike other human beings (other than Adam and Eve before they sinned) He was not subject to death as a punishment for sin, but He accepted it on our behalf. When He died, he really died. His soul and His body were separated and for three days He could be spoken of as "not a man". See https://www.newadvent.org/summa/4050.htm#article4 for the details. Follow that up with https://www.newadvent.org/summa/1075.htm#article4 for how that relates to us. One particularly striking quote - "[c]onsequently, to say that Christ was a man during the three days of His death simply and without qualification, is erroneous. Yet it can be said that He was "a dead man" during those three days."

Jesus is also fully God. His divine nature is perfect and unchanging. His divine nature is immutable (not merely immortal) and was not subject to death. Thus Jesus was subject to death in His human nature not in His divine nature.

Any ranked matchmaking game is designed to addict you by the prospect of being ranked as elite. They have a number of insidious methods to keep your ranking low, some are even patented by the game companies themselves!

For example, if someone is getting too high, it’s nothing to pair that person with a known deserter for 1-3 games to drastically slow their progress.

> Imo V2G, and V2H is unnecessary and add too much complication

I believe that's more a function of auto makers (and charger cos) not trying to do much about it (and grid cos not caring), than a technical issue. The benefits (especially if V2G) are quite significant.

I doubt any car owner will say no to earning revenue from something that costs them almost nothing. The problem is more of "how do we get there at scale". (Disclaimer, I studied this topic in my thesis.)

The article I'm commenting on said its author used seek and read, so I don't know if maybe for some reason they did do that instead of pread(), which it also mentioned. I didn't want to optimistically assume otherwise. Is pread() available in the Golang standard library?

https://github.com/golang/go/issues/19563 is someone using os.File.ReadAt, which is a method name that makes me even more uncertain. But there's also syscall.Pread apparently, so it should be fine?

If you are making only one system call, the 25× crossover point is 800-some bytes by my measurements.

Yeah cryptography mostly (but certainly not all) math but it accounts for a negligible (pun intended) portion of interesting security work.

AI is a lot of math, especially if you hang out with the quasiconvex optimization crowd, but a vast majority of work in that field can not properly constitute “theory”

I think it’s clear in practice that computer science has officially strayed beyond whatever narrow bounds people originally wished to confine it to.

Those are a lot of "presumablies". Maybe you're right. Or maybe it was mostly obscured so you really couldn't tell. How do you know it was open and he was eating? How do you know there were other kids around and he wasn't solo? Why do you think the body language would be so different? Nobody is claiming he was using a gun or threatening anyone with it. If you're just carrying something in your hand, I don't know how you could tell what the object is or isn't from body language.
by fendy3002 | 2025-10-24 03:53:28+00:00
a bit unclear from my statement before but that's the point. Something that feels easy is actually much more complicated than that. Like weather, runway condition, plane condition, wind speed / direction, ongoing incidents at airport, etc. Managing all that scenario is not easy.

the similar things also applied in driving, especially with obstacles and emergency, like floods, sinkhole in Bangkok recently, etc.

> Never took a political science class I see.

Actually I did and I'm quite good at it. However, not all classes are the same.

> Of all the major political ideologies, the one that is the least like fascism would be libertarianism.

Only if you haven't thought about it long enough or haven't taken the right classes.

> Now if a specific person or party is actually libertarian, that's another story.

It's not another story, it's where libertarianism always ends, it's in its DNA. In other words, cute baby-libertarianism has nothing to do with the finished product.
SHOW HN: Remember the last time you used Sticky Notes?
by VatanaChhorn | 2025-10-24 03:55:13+00:00
I remember the feeling of using physical sticky notes. I would dump small thoughts, make quick checklists, and toss them once they were done. Life felt simple and convenient.

In this digital age, we’re prone to using note apps or to‑do list apps to replace sticky notes. I’m not saying there’s a problem with that, but most of the time I don’t need a full on note app or a full on to‑do list.

So how does a digitalized, transitional sticky note help my productivity? Imagine this: you’re going to the grocery store. Most of the time, you would use your note app with a checklist to list the items you want to buy. I’ve talked to a couple of close friends, and that’s how everyone does it.

The problem is:

- The notes (which are supposed to be for important things) end up cluttered, and over time, it’s harder to find the important ones because they’re buried under throwaway lists.

- When I arrive at the grocery store, I have to open the note app and sometimes even search for the note just to view the items and tick them off. More often than not, those notes stay there alongside my important ones because there’s no simple way to remove or archive them once I’m done.

How we used to do it with sticky notes:

- Note down the grocery checklist, and the widget will automatically update on the home screen.

- Arrive at the grocery store → check off all the items I’ve picked up.

- The sticky note automatically archives once every checklist item is ticked.

This simple workflow keeps my notes uncluttered and actually improves my productivity.

Feel free to try it out at https://apps.apple.com/ae/app/sticky-notes-notes-todos/id6754217076?platform=iphone.

I am open to constructive feedback.

You're being downvoted but I get where you're coming from.

The dismay is from not needing to speculate, wonder or theorize about why he did this pardon. It's a quid pro quo pardon for helping the Trump family make billions of dollars in under a year using the office of the president. The corruption is entirely flagrant and open.

Yeah, it's a forum of smart people, but none of those smarts are oriented to dealing with this kind of problem. There's a system but it's non-functional, laws but they're ignored, the tools are raw political and social power. It's going to take a while to figure out what to say and do about the slide from normal, functioning democracy into semi-theocratic banana republic.

Not attacking you but using your message to say to anyone reading: Is there a lesson here about what our AI future looks like? The OG thread comment is using summarized information to induce anxiety. When everyone has a 'suped-up AI bot running around the net for them, how much more noise like this is there going to be? How many people will have armies?
