Did you learn to read Polish or English at that age? As someone whose first language is written as it is spoken, I believe that reading English for English kids is much-much-much harder. Reading in a language with a letter-sound correspondence is entirely trivial. You speak that language, you learn the characters, you're done. Reading English requires to learn an entirely new language, hundreds of words. (Especially if reading English is taught simultaneously with writing English--I don't know about that.)

I can't find any real studies about this subject with numbers; how much effort does it take for an Italian/Spanish/Finnish/Polish/.. kid to learn to read vs for English kids. Or, for example how many of them are able to 'teach themselves' to read just by looking at the picture books, and asking parents about letters.

> one successful attempt at addressing this problem is Japanese late night anime schedules

Depending on the channel, the "new date cut-off" (more accurately: 日付変更) sometimes varies. Some channels start the day at 5am, others at 4am, and so on. Because of this, one gets to see wild things, such as a time-table scheduling a show at "29:30" whereas another channel would write "05:30".

In any case, your claim is correct. The people who stay up to watch late-night shows do not consider their day finished around those hours, and the times are intended to reflect that. However, there is still inconsistency around the hour of the new day.

A similar issue exists in video games. I know of one game that "starts the new day", so to speak, at 5am, and another game that does so at exactly 12am. To add further confusion, many Japanese websites and games are designed with the assumption that the user is always in Japanese Standard Time. (Most Japanese do not travel abroad, and Japan itself has exactly one time zone, thus Japanese programmers rarely ever think about time zones). Thus, when overseas, you may see the new day in a video game start at 1pm local time!

Agree with everything you're saying here, but to be fair I think the analogy with Progressive JPEG doesn't sit quite right with your concept. What you're describing sounds more like "semantic-aware streaming" - it's as if a Progressive JPEG would be semantically aware of its blob and load any objects that are in focus first before going after data for things that are out of focus.

I think that's a very contemporary problem and worth pursuing, but I also somehow won't see that happening in real-time (with the priority to reduce latency) without necessary metadata.

» landlords will always increase rent to the limit

In your own words, a business will run out of business quickly if supply and demand do not match. So unless you are confident that there will be a buyer, you cannot raise prices infinitely.

» because a living space is a basic necessity

While most people can live without a netflix subscription (hence they cannot raise prices infinitely and still expect to find buyers) most people prefer to live in housings. A housing is a basic necessity hence as a landlord you can confidently raise prices to the barrier of an affordability limit.

» Something else will get expensive in the meantime

Lets assume electricity prices get really cheap because humanity discovers fusion reaction. Well guess what, now landlords will increase the rents again because they can.

Hope I expressed myself to your liking. I mean you just walz in here and start lecturing people about capitalism, maybe you should change your careerpath and become a teacher.

A crude explanation might be like this - if you look at graphs of sin and cos, you'd instantly recognize their symmetries, but what if you're given the graph of a linear combination of them, and asked to decipher the coefficients?

Naively, you'd evaluate the functions at every point by trial & error until they much the shape of the given graph. Or use the symmetry of sin & cos to combine them constructively and destructively (peaks and valley) and to match the given shape.

FT & QFT are "shortcuts" that help to decipher the correct combination of basis functions.

I write things down and it helps, esp. when I manage to keep it minimally structured: write down a question, then write an answer, split different topics.

Generally I think it is a question of method. If I was to produce a physical thing I would know the steps. One of steps would be a drawing in a known form, with known ways to indicate what is important. With software there is no such a standard form.

> where a community bans running a business from a residence and accidentally wiped out a major tech company from being founded.

the benefits of the business goes to the private person running the business from their residence.

But the externalities falls to the community (or at least, shared by the community).

Therefore, a community wanting to ban a business from a residence is very valid imho.

However, if the business could either prove there are no externalities, or compensate for it in some way, then there should be room for negotiation, rather than a straight outright ban.

> Here’s Adam’s story of how living by UTC transformed his productivity, and why it might work for you, too.

> Give it a try, you might find it as liberating as I do.

Did you miss these quotes, or are they also part of the absolutism? Here are some ways I read it, which seem like fair interpretations and also don't make the author stand out as being particularly dogmatic or authoritarian:

Considering the quotes I provided, it seems likely that the author may have been suggesting that we stop using timezones as a society in order to mitigate the only two downsides that they listed, since those downsides only exist as a result of society still using timezones while they as an individual stopped using them.

Another way to read it could be that the author made a statement they believe is probably true ("timezones should be abolished") but they were not fully convinced. To gain confidence, they decided to gather further information: "I began with myself...To my surprise, it was easy" and then ended with two downsides of their experiment, suggesting that they realize it may not be a perfect solution, at least right now.

A third way one could read it is to consider that the author didn't propose fines, jail-time, or any other specific penalties for continued use of timezones in their hypothetical world. Without enforcing a penalty, what does it even mean to "abolish" a timezone? In the context of the whole post, it seems to be more of a thought experiment imagining what could be if society as a whole switched, rather than a prescription of what must be.

The unwillingness to engage with the author's thought experiment strikes me as more dogmatic than anything the author wrote, but perhaps I am not fully considering other possible interpretations.

We use honor pledges not to reduce cheating directly - but rather, to create incontrovertible evidence that the student was aware of the course policies. This supports those rare cases where a student chooses to fight a plagiarism case and claims ignorance of the policy, especially in cases where it may not be University-wide policy - e.g. a policy against AI usage. Students can argue they didn’t read the syllabus, missed the first day of class, etc. but have a harder time arguing they signed a pledge without reading it.

We regularly catch cheaters in our classes; I do so every term and report all the cases I see up to the dean. In my experience these have not resulted in catastrophic declines in teaching evaluations; the few unhappy with getting caught cheating are drowned out by the 80-90% who don’t cheat.

It is actually critically important that institutions take cheating seriously. Rampant, well-known cheating can tank the reputation of a program or institution, or at the very least serve to cheapen the value of the degree.

I can understand where you are coming from, but in the cases we had to deal with, there was absolutely no room for ambiguity. To put things into perspective, those were students who did not know what a HashMap is or could not derive the algorithmic complexity of two nested for-loops, yet somehow cheated their way into a master's level course. With the current level of oversight, degrees obtained after 2022 are basically worthless.

I did a chat with Gemini about the paper, and tldr is... * They introduce a loop at the beginning between Q, K, and V vectors (theoretically representing "question", "clues" and "hypothesis" of thinking) * This loop contains a non linearity (ReLU) * The loop is used to "pre select" relevant info * They then feed that into a light weight attention mechanism.

They claim OOM faster learning, and robustness acro domains. There's enough detail to probably do your own PuTorch implementation, though they haven't released code. The paper has been accepted into AMLDS2025. So peer reviewed.

At first blush, this sounds really exciting and if results hold up and are replicated, it could be huge.

Yeah, and the big caveat with this approach is that it scales quadratically with scene complexity, as opposed to the usual methods which are logarithmic. Their examples only have 4096 triangles at most for that reason. It's a cool potential direction for future research but there's a long way to go before it can wrangle real production scenes with hundreds of millions of triangles.

I must have missed that quote, I seem to be unable to find that text in the post.

I don't know, it kind of seems like it was:

They're making it sound awfully optional if their intent was to put you in jail if you didn't do it.

You’ll either need a remarkably good in-brain integrator or something that measures energy instead of power. The data is noisy.

I just pulled the data from a US model Neorest, and I see a bit over 600Wh in a day. So better than 40W, but not amazing. It does drop below 1W for short periods, so it’s not actually the electronics wasting power at idle.

> like China's done for .. 75 years

China did that for political reasons. The Republic of China used five, and Russia uses two timezones across those longitudes. Similarly, I also find it quite weird that France and Spain are in CET. France shifted when it was occupied in WWII, but maybe it's justified to remain in CET to reduce friction with the economies of its eastern neighbors. Whatever. Vive la weird. Countries do that to themselves.

A deviation of half an hour from noon is barely perceptible unless you use a sunclock. People can roughly estimate when the sun will set by just looking at local time and considering the current season. What throws a wrench in the works is daylight saving time. I fully agree that DST a huge annoyance and that its benefits were always rather situational.

I want to be able to click-and-drag. For example, in this row

1 2 |x x |

if I left click the second cell and drag right it should mark all the blank cells black.

Similarly in the inverted case, if I have marked cells and right-click-and-drag next to them it should mark the empty spots I cross over with Xs.

Important: this doesn't change the state of any cell that wasn't blank to start out. You should have to click on a marked cell to clear it (or right click to replace it with an X). And similarly to above, if you drag, it should change only the cells you touch that match the starting state of your original cell to the new state.

> but centering on the freezing point of water seems more useful overall

But why? Knowing the freezing point of water (at sea level, mind you) is only rarely useful to me in daily life. I think the eutectic point of salt and water (that is, the lowest point at which it's possible to cause ice on the roads to melt by adding salt to them) is marginally more useful; this happens to be about -6F or about -21 C. Perhaps it's a bit more important for farmers who need to know whether their crops will freeze overnight, but as a lifelong city/suburbs dweller who knows next to nothing about agriculture I couldn't really say. At any rate, most people are not farmers.

I'm asking this somewhat rhetorically: I don't really care about Celsius vs. Fahrenheit. The pros and cons between the two are so vastly outweighed by the utility of having a global standard that I really wish the US would switch. I'm just pointing out that I don't think that one particular physical property of one particular substance makes for a very strong argument either way.

Spain has a hard time figuring out how to get their sewage system to handle regular toilet paper and many regions/places require you to deposit the toilet paper in trash cans next to the toilet. That being said, I think there are better options like a clever public awareness campaign, banning the claim of being flushable, required packaging that says not to flush, requiring to be packaged with plastic bags for disposal, or even just accumulating all the costs of issues from the wipes and charge them to the industry as a whole in various taxes and fees, which will push the incentive to solve the problem on the industry.

I used to use wet wipes and flushed them, now I have a bidet and have only ever used wet wipes when traveling, where, ironically, Spain’s issues with basic things like flushing toilet paper, make disposing/not flushing wet wipes easy because many bathrooms have a lidded trash can next to the toilet/in the stall.

Ironically, their bigger issues produce a solution to a different, bigger problem.

Note: Yes, I’m aware it’s not everywhere in Spain or only Spain, but I am curious to hear where everywhere everyone has encountered having to put their toilet paper on a trash can instead of flushing.

In many areas of computing, I hate setting pen and paper exams.

Asking people to write Java (or whatever) on paper is crazy, it doesn't really line up with anything you would ever do in the real world, and expecting people to memorize the signatures of functions feels like a total waste of time.

On the other hand, we have to accept that LLMs are I think, at this point, better than over half of all 1st year University students, so we can't let students use LLMs, without either letting half of students pass with no effort, or making tests harder and failing half of students -- and that isn't a long term solution, as I imagine LLMs are just going to keep getting better.

I think there's a world where you would use the code structuring of RSCs to compile a static page that's broken down into small chunks of html, css, js.

Basically: If you replace the "$1" placeholders from the article with URIs you wouldn't need a server.

(In most cases you don't need fully dynamic SSR)

The big downside is that you'd need a good pipeline to also have fast builds/updates in case of content changes: Partial streaming of the compiled static site to S3.

(Let's say you have a newspaper with thousands of prerendered articles: You'd want to only recompile a single article in case one of your authors edits the content in the CMS. But this means the pipeline would need to smartly handle some form of content diff)

> I don’t really know what it is. Maybe a sense that because they’re using a tool that it’s not cheating? Thinking they’re less likely to get caught because it’s not identical to existing work?

That would make sense. The logic that they are not copying work from another student or copying someone else’s “efforts” so to speak.

Another aspect is how easy it is. It’s not having to find someone to copy it from, or search online and so on. It’s “just open an llm chat window and ask”.

The worst part is those that don’t cheat will hear how so and so uses llms to do homework and nails all the answers unpunished while they are barely managing, trying to do honest work. That stuff is soul killing.

There seems to be a growing gap between the people who define "community" as the group of people who live in and wish to direct the changes in the area they are in. And the people who define community as the group who receives the benefits of government intervention.

YIMBYs is a silly term, since its usually a developers talking about forcing changes in someone else's neighbourhood. Considering the input they like, it's only from the second definition of community, notably people not currently in an area, or standing to endure the downsides.

Really, no law enforcement agency should have access to anything that's also not available to the general public. It's also 2025, there's zero reason that all records, including searches using these systems aren't public record that are freely available online.

There is constant abuses of these tools and the reason they lobby to keep them secret or make it difficult to get any information any usage is because they know they're abusing their purpose. The agencies that are tasked with oversight are in collusion with them.

At this point 100% transparency on any law enforcement entity that acts within the borders of the US should be demanded. This way it's at least possible to get some oversight.

Right now we're in one of the worst human rights abuses that happen inside the United States since the internment of the Japanese. This is being pushed by the Trump administration under the guise of removing individuals were in the country illegally. What's actually happening is ICE, with the full cooperation of nearly every local law enforcement agency, is sending out a detainer for anyone without regard to any new process or probable cause. This includes picking up US citizens in addition to legal immigrants. They are detaining these people for weeks or months and not even bringing some of them to court for a basic probable cause hearing.

Their games get even worse. I have a friend who is a legal immigrant to this country that has been picked up and detained for over a month, they have lost their job and they have lost their apartments and they have lost in savings that they have. They still have not had their court date yet even hear why they are being detained. Then last night I found out they have been moved to the El Paso deportation center but they have their court date scheduled in Miami on June 3rd. ICE is literally denying due process by shipping them to Texas when they know there is a court date that has required attendance in Miami.

When I spoke to a lawyer they said this is the normal tricks they do now. They will ship someone far away and they will not return them for their court case so there is a summary finding against them and an official deportation order listed. Why my friend got shipped to a deportation facility without an actual deportation order without an actual day in court is ridiculous.

No person conservative or liberal or anywhere in between should be in support of the basic denial of due process that is the foundation of our country. The use of rights cases are slowly making their way through the courts now. They will only continue on for the next many years. Those law enforcement officers who are willfully violating their oath to uphold the Constitution Will likely never be held accountable but we taxpayers will end up paying millions of dollars for those who are being abused.

This is why I am an advocate for the complete and utter removal of qualified immunity. Every law enforcement officer that is participating in this should not be able to say, I was only following orders. These idiots clearly have not studied their history.

> The coolest thing here might be the speed: for a given scene RenderFormer takes 0.0760 seconds while Blender Cycles takes 3.97 seconds (or 12.05 secs at a higher setting), while retaining a 0.9526 Structural Similarity Index Measure (0-1 where 1 is an identical image). See tables 2 and 1 in the paper.

This sounds pretty wild to me. Scanned through it quickly but I couldn't find any details on how they set this up. Do they use the CPU or the Cuda kernel on an A100 for Cycles? Also, if this is doing single frames an appreciable fraction of the 3.97s might go into firing up the renderer. Time-per-frame would drop off if rendering a sequence.

And the complexity scaling per triangle mentioned in a sibling comment. Ouch!

I would love to know which wipes those are, because I have never come across any that are even remotely actually dissolvable. If you know of a brand, I really would like to know which that is. Have you ever tried putting one in some water just to see how dissolvable they are?

There is also that they’re kind of a contradiction in terms anyways, they’re wet … wipes. If they were dissolvable in water, the wetness of the wipes would cause dissolvement.

What many people are not even aware of is that even all high end toilet paper in the USA is a major headache for sewer systems because even that “paper” does not dissolve well at all, because they’re so focused on making the “paper” feel soft or be durable, it’s technically not even paper anymore and actually more like a cellulose felt.
