When I first tried letting Cursor loose on a relatively small code base (1500 lines, 2 files), I had it fix a bug (or more than one) with a clear testcase and a rough description of the problem, and it was a disaster.

The first commit towards the fix was plausible, though still not fully correct, but in the end not only it wasn't able to fix it, each commit was also becoming more and more baroque. I cut it when it wrote almost 100 lines of code to compare version numbers (which already existed in the source). The problem with discussing the plan is that, while debugging, you don't yourself have a full idea of the plan.

I don't call it a total failure because I asked the AI to improve some error messages to help it debug, and I will keep that code. It's pretty good at writing new code, very good at reviewing it, but for me it was completely incapable of performing maintainance.

congratulations, you spotted yet another case of hypocrisy!

I don't think people are capable of existing in the world without slavery-like systems: owning the copyright, thriving in late-stage capitalism at expense of others, leading the gang, you name it - these are primary drivers of clout (control, power), and we stupid monkeys will do everything to get more of that addictive clout, with only a few exceptions.

I would like to be able to search old videos I’ve seen sometimes. Like to find that one recipe I saw or to pull out that one fact I thought I heard. Or sometimes just to listen to a song that later got made private or deleted outright. When YouTube deletes a video it doesn’t even leave the title in your playlist so it can be frustrating to try and find the same thing again.

The article isn't using the graphs to talk about a difference between 2015 and 2017, but about the overall level, so it would indeed be surprising if there had been a large change between those years.

But there are several demographic variables that show substantial differences between groups (and sometimes over longer timescales within a group), so I think it would be more enlightening to look at all of them, rather than letting someone pick their preferred comparison and then trying to argue with that.

Education is a system that resists change.

Any time you research an educational innovation, part of the work is to measure to what extent the implementation is faithful to the intent. Education research is not like physics research.

I absolutely apply that understanding when I read research about major changes in the way reading is taught.

I actually think the only way to be confident is to do some kind of primary research yourself. Otherwise, tread lightly and skeptically.

Waiters in the U.S. make more, due to tips, despite the U.S. having a lower minimum wage. Do you think American waiters want to make $2k/year less? That's nearly 10% of their income.

And that's before even factoring in the tax benefits, which is exactly what this article is about! No tax on tips means nearly all of that income is untaxed. French waiters pay 11% taxes, and British ones are in a 20% tax bracket. The difference widens even further.

Tips allow American waiters to earn more, and no tax on tips makes them take home even more. Hand-wringing about how the American system pays less than the European one is innumerate.

The is not the xkcd I thought it would be. This is the xkcd that Claude code makes me think of:

https://xkcd.com/1205/

I don’t feel Claude code helps one iota with the issue in 1319. If anything, it has increased the prevalence of “ongoing development” as I auto mate more things and create more problems to solve.

However, I have fixed up and added features to 10 year old scripts that I never considered worth the trade off to work on. It makes the cost of automation cheaper.

It is not exactly Altman’s company. It was founded in 2013 by David Kirtley, John Slough, Chris Pihl, and George Votroubek. These three won the ARPA-E competition around then. Altman funded the company more recently and is on the board. But he isn’t a founder or executive there.

At this point I am 99% convinced that AI coding skeptics are nothing short of Luddites.

They would be like "but a robot will never ever clean a house as well as I would", well, no shit, but they can still do the overwhelming majority of the work very well (or at least as good as you instruct them to) and leave you with details and orchestration.
Show HN: Fast Elevation API with memory mapped tiles
by anaj123 | 2025-08-02 21:12:25+00:00
I recently wrote and launched a high-performance Elevation API, built from the ground up, in C. I was highly inspired by the handmade community and I was intrigued by the idea of handling fairly large datasets and optimizing caching and smart prefetching, and to cream out maximum performance in terms of latency and handling large loads.

The whole thing is built from scratch. I wanted to roll my own high performance server that could handle a lot, mostly for the technical challenge but also because it brings down hosting costs.

At the core is a hand made TCP server where a single thread handles all I/O via epoll, distributing the events to a pool of worker threads. The server is fully non-blocking and edge-triggered, with a minimal syscall footprint during steady-state operation.

Worker threads handle request parsing and perform either direct elevation lookups for single- or multi-points, or compute sample points along polyline paths.

The elevation data is stored as memory mapped geotiff raster tiles, The tiles are indexed in an R-tree for fast lookup. Given a coordinate, the correct tile is located with a bounding-box search algorithm through the tree, and the elevation value is extracted directly from the mapped memory. If the tile is missing the data, underlying tiles act as fallback.

I also implemented a prefetching mechanism. That is, to avoid repeated page faults in popular areas, I employ a strategy where each tile is divided into smaller sub-tiles. Then, I have a running popularity count per sub-tile. This information is then used to guide prefetching. More popular sub-tiles trigger larger-radius prefetches around the lookup point, with the logic that if a specific region is seeing frequent access, it’s worth pulling in more of it into RAM. Over time, this makes the memory layout adapt to real usage patterns, keeping hot areas resident and minimizing I/O latency. Prefetching is done using linux madvise, in a separate prefetch thread to not affect request latency.

There’s a free option to try it out!

> More likely scenario, your children, grandchildren or other family members go through your shit after you pass away

I think that's not really likely. I'm pretty sure if you poll you'll find that few children care about their parent's "stuff". You can find plenty of people who've lost parents who found that they didn't have any interest in going through their parents stuff and then from that realized their children would be the same to them.

Most children aren't going to dig through anything more than a physical photo album, and when they do, the only pictures that are relevant to them are those with people they know. The rest only have meaning to the dead parent. They aren't going to dig through hard drives or CDs unless they are searching for financial documents so they can finish up their parent's financial affairs.

> discover stuff about you that perhaps you never wanted to share

I do worry about that. I just tell myself I'll be dead so it doesn't really matter.

Just want to point out that having a cheaper living situation doesn’t preclude homeownership later—it makes it more feasible.

I’ve lived in SF (communally) for about 10 years now. The first 5 years I lived here help me build up my savings, and then a housemate, my wife, and I bought a building in the city that now houses 8 adults. I definitely could not have afforded this paying for a one bedroom in the city, and living with roommates meant I had lots of time to find people who would be willing to go in on a house with me!

But even if this weren’t the case, over 5 years we probably saved ~200k in rent. Putting that into the stock market would typically yield much better returns than owning a home (which is typically a wash after mortgage interest is factored in).

But then companies could sue to wipe out the centralized repo. So to be safe, you'd copy things to the central repo and also have a local copy. ;-)

Next, you try to centralize all the private copies so only one person has to keep theirs. Solution is end copyright for things over x years in age. Instead in the us we keep pushing back the date.

"I have seen something further under the sun, that the swift do not always win the race, nor do the mighty win the battle, nor do the wise always have the food, nor do the intelligent always have the riches, nor do those with knowledge always have success, because time and unexpected events overtake them all." From Ecclesiastes 9:11, which came to mind immediately when reading this.

The book itself has more than a few apt / sobering observations like this, concluding at 12:13, somewhat abruptly after a sort of 'case study' on the futility of life without God.

> Yet to talk about the amount of mining, its carbon footprint and pretty much irreversible or really high cost extraction/restoration of batteries apart.

Do you also have similar thoughts on all the infrastructure needed for oil, or is that not to be discussed?

I always wonder with the "all the mineral-mining!!!" crowd, do they think the oil infrastructure just arrived overnight? And there was no cost (money and long-term ecological) to it all?

I am dyslectic (as my username suggest), and i was taught the method phonetics in school (in Sweden, not the us), and transitioned naturally to whole word (which i suspect is the intention in that method).

I initially struggled to pick up reading, as phonetics is a very difficult method if i cannot tell the letters apart half the time. Once my reading speed started to pick up, it was thanks to dismissing phonetics entirely and reading by whole word, but that leap took time.

Talking with others in adulthood, i seem to rely more on whole word than is typical. Others get tricked up by incorrect letters in words, yet i match the word anyway if it has the right shape. The below sentences read to me equally.

- I am unbothered by spelling mistakes to a much higher degree than others

- l ma unloethsred bs sqellnig mitsakes la a mucb hgiher degeee thna ahters

Another issue i encountered is finding reading fun. My parents read a lot for me to make me like stories (which is commonly given as advice to get children reading), but this backfired. My comprehension and appreciation of stories were years ahead of my capacity to read them. Being barely able to get thru "harry potter and the philosophers stone", but preferring "The Lord of the Rings".

I now work in a field where reading highly technical text is a major part of my day. Peculiarly, my lower reading speed from my inability to skip properly (something i struggle with because of aforementioned dyslexia) seems to raise my reading comprehension. I many times found details or explanations others don't because they skimmed over important words or phrasings in highly information-dense text.

---

I really think foreign words should be read phonetically. Taking the first letter and guessing is an insane way to teach to kids to me. I could imagine they don't pick up new words since they learn to guess words they know instead. Using contexts may become important later as we learn to skim-read, but i don't think we should teach kids to guess anything as they first start to learn.

https://www.sciencedirect.com/book/9780124159501/the-art-of-... - This is the current edition.

I'm only comparing the TOCs here:

Chapters 1-6 have, unless I missed something, the same chapter topics and section titles.

Chapter 7 seems to be reorganized a bit and adds an exercises section.

Chapters 8 - 16 have one extra section for exercises each, I'm not seeing (quick review) any other differences in section names.

Chapter 17 becomes Chapter 18, adds an exercises section.

Chapter 18 becomes Chapter 20, several additional sections.

So the earlier edition is missing Chapter 17 "Data parallelism" and Chapter 19 "Optimism and manual memory management" from the newer edition. Only the missing Chapter 17 would impact the reading group plan since it is covering chapters 1-18.

I remember my first music (note reading) lesson. We got a paper with sentences, and the teacher replaced each word with either 'titi' or 'ta' and we had to repeat it. Our homework for that week was an A4 paper full of words and sentences, and we had to replace them with 'titi' or 'ta' as made sense from context. I somehow managed to get a good grade, but it confused the hell out of me, and made me think of giving up music as too hard. I remember it bothering me the whole week.

The second lesson, the teacher says: 'Now we have to learn some hard words. The 'ti' is called a quarter note, and the ta is a half note'. Finally, the whole thing started to make sense to me. Then the teacher says: 'But don't try to understand that, these are very hard words for adults, just memorize them and do what makes sense from context.' Trough that lesson, the teacher kept stressing that same message: Too hard, adult words, do what makes sense instead and use the hard words only to impress the outsiders.

I've kept a deep distrust for teachers telling me to do what makes sense in context. I've always kept asking for the actual rules and correct words instead, however complicated they were. It happened a few times later in life too, like my economy teacher giving 'debit' and 'credit' guidelines based on vibes without telling they should be balanced, with subtraction being complicated math according to her.

There are people who don't care at all, but most people will drive around the speed that the road encourages. That includes things like how straight the road is, what kinds of interactions, the presence of sidewalks, trees, and many other clues.

Neighborhoods can be designed to send signals about the appropriate speed, without signs or rumble strips or speed bumps. Some people will ignore these, just as they'll ignore signs, but most drivers will do what they expect for that kind of road.

I'm going with envy. Athletics is a completely different skill from software, and one that is looked down on by posters here, judging by the frequent use of "sportsball". "Sportsball" players make huge salaries? Whatever, not my thing, that's for normies. But when software researchers make 1000x my salary? Now it's more personal. Surely they are not 1000x as good as me. It seems unlikely that this guy is 1000x as skilled as the average senior developer, so there's some perceived unfairness, too.

But I counsel a different perspective: it's quite remunerative to be selling tulips when there's a mania on!

> We'd need someone who is informed on the developmental process of math skill to comment on "times tables".

(I feel somewhat qualified...)

It is a mistake to make the kids memorize the times tables before they intuitively understand that multiplication is a repeated addition (or visually, that multiplication is a rectangle). The right moment to memorize comes a few weeks or months after they can calculate the result without memorizing. I think it is safer to wait, because many parents would be tempted to make it prematurely, in order "not to waste time".

Generally: understanding first, memorizing later. If you memorize first... many kids won't even try to understand, because "they already know it". The problem is, if you remember without understanding, there is nothing to correct you if you make a mistake. An incorrectly remembered fact feels exactly the same way as a correctly remembered fact, and you have no alternative way to check.

Also, memorizing instead of understanding is a strategy that works well in short term and terribly in long term, because memorizing a small thing for a few days is easy, but then you forget it (kids famously lose a lot of what they learned at school over summer holidays), and when the memorized things accumulate, it becomes too much and you start confusing them. Actual understanding takes more time, but it can survive the summer holidays, and already understanding many things makes understanding an additional thing easier.

(But when the day comes to memorize the times tables, spaced repetition is your friend.)

In my opinion? Qwen3 does live up to the benchmarks, it leaves Sonnet 4 in the dust quality-wise if you can get a fast enough tok/s to use it. I haven't tried GLM or Llama Scout yet, nor do I have a particularly big frame of reference for the quality of Opus 4.

You might be able to try out Qwen3 via API to see if it suits your needs. Their 30b MOE is really impressive, and the 480b one can only be better (presumably).

...you are just explaining that it was a global policy for a local problem. I don't know what to tell you. The global policy is 20mph.

It sounds like a big impact if you don't know anything about statistics because, obviously, you would need to know some measure of variance to work out whether a 19% YoY decrease was significant (and I don't believe the measure that reduced 19% was accidents either). This hasn't been reported deliberatel but that is a single year and that is within error. You, obviously, do need more policing...I am not sure why you assume that no policing is required.

People driving without a licence/insurance are more of a problem than someone going 30mph...obviously. Iirc, their rate for being involved in accidents is 5x higher. If you are caught doing either of these things though, the consequences are low. Competent driver going 30mph though? Terrible (there is also a reason why this is the case, unlicenced/uninsured driving is very prevalent in certain areas of the UK).

I'm in the market right now. Anecdotally, it seems like there's more inventory available today than at any time in recent memory, but attractive properties still sell fast while loser properties pile up.

I'm not quite sure what the underlying explanation is. Perhaps there's a class of sellers that bought or refinanced at low rates and high valuations and now that rates are up and valuations have slid they can't find buyers that will accept the previous high valuation.

This made be curious, so I looked around. FWIW, healthcare constitutes ~11% of the workforce in the US. It's ~16% in Germany, ~10% in the UK, and ~5% in France.

As a percentage of GDP healthcare is far higher in the US, of course.

People who live on the internet assume this is true because they only deal with people who also live on the internet. Just because we're not all documenting everything that we do to a nebulous public doesn't mean it doesn't happen. Much of what happens in the social world isn't articulated or available for scientific study. You might be surprised to know that bars, clubs, gyms, concerts, trivia nights aren't empty. "In decline" is the sort of state that's can only be articulated in abstract terms. Stop rationalizing your loneliness as a societal ill. Getting to know people is your problem and society offers many solutions.

I really wonder what kind of world people live in who write such articles and what kind of world people live in who seriously read them.

I know some friends who are total believers in llms solving all problems. I keep pointing out the issues you are raising. They just want to believe in magic. They also believe in this WA fusion company, even though it has problems as raised here, never demonstrated a working system really.

I see similar behaviors in people that believe tesla has almost cracked self-driving, just trust them because it will start working "real soon now", and also optimus robots from tesla will take over (but there's no brain for the robot, not even a demo, all the demos were remote controlled but they don't care!).

Why ever would you compare children and immigration? I love my parents and I’d have solidarity for my country fellows (France here).

Immigrants don’t generally earn much, let alone work legally and pay taxes. They are not paying our retirement. They require doctors and produce our “medical deserts” (the name we use in France where social security fails because of lack of practicians). They also wouldn’t fight for us if, say, Islam invaded us — in fact they are fighting full-force against us here.

Immigrants are not de-facto children. They do not love us, and no-one asks them this question on the path to immigration.

I think it's more about quality of life rather than extending it - enjoying outdoor activities (skiing is a blast!), enjoying looking good and being in shape, able to do all my own yard work and snow shovelling etc without it being an effort.

Now, while I choose to do things that I enjoy (and the skiing is purely for enjoyment, even though it requires a lot of energy), I will say that part of the motivation for wanting to keep in good shape is seeing what happened to my Dad who had an office job (professor) and didn't exercise at all other than a bit of walking to the grocery store etc, and in his old age had all sorts of pinched nerve and mobility issues due to lack of muscle tone and strength, and realized it was too late to do anything about it.
