Came here to write this. To add to that, the book "The Art of Learning" is a great example of this; Joshua Waitzkin tells how his approach to learning saw him reach the pinnacle of both Chess and Tai Chi. From the outside it might just seem like a "genius" who just so happened to have innate talents for both of these highly disparate forms of competition, but his story paints a different picture.

My own approach to learning is very similar, and that's before I read this book. But it was not an approach that came naturally to me. I was never good at school. I was never good at paying attention to things I didn't see a _reason_ to pay attention to. But I realized early on that my propensity for "hyperactive behavior" (as they called it at school in the early 90's) meant I couldn't rely on the "standard" way of learning to work for me, and that if I wanted to learn the things I did care about, I needed to find my own way.

This is in no way me trying to brag, but to give some context to why I challenge this kind of mindset whenever I'm faced with it, including (and without much success) in my own mother who keeps bringing up "I wonder who you inherited this skill from" whenever I learn something new, let me list some of the activities other people tell me I'm talented in:

* Software architecture and design

* Indie game development, including 2D and 3D engines from scratch in multiple languages as well as game design

* Graphic design

* Playing the piano

* Multilingualism (Norwegian, English, German, Dutch, Japanese)

* Videogames -- I'm particularly good at Smash Bros. Melee

* Hiking

* Body control - I can do push-ups while hand standing

* Conversation and hanging out - I make people laugh and have a good time because I have a lot of topics of interest to keep conversation flowing, and I set aside my ego to make sure the group has fun as a whole

Again, I'm not bragging, because I'm not a master in any of these disparate activities, and I also firmly believe this is something almost everyone can do. There is no "genetic" or inherited talent here. I was terrible at all these things and had to apply myself and experiment with constantly adaptive reinforcement techniques to get good at every single one of them. I grew up with asthma, but started practicing martial arts in spite of it. If I have a talent, it's simply curiosity. Everything else was an uphill struggle where I spent longer getting _OK_ at every single activity than most, but because I kept at it, I eventually got better than the average.

And one of the major factors of that is increasing my practice surface area in everything, which often ends up overlapping existing knowledge in surprisingly deep and fascinating ways, which in turn keeps me interested and curious. It's a feedback loop of learning.

Serial over IPMI, plus ipmi power control is pretty good when it works. Supermicro X10 and newer was pretty nice. X9 and X8 not as nice; it's not helpful when the serial over ipmi drops during reboot and doesn't come back in a reasonable amount of time, and then the graphical mode needs ancient java webstart with os and platform specific jni, oof.

I tried it two years ago. Don't remember why but I think it helped to clear my head. Like dumping a RAM or throwing out the trash. And it indeed worked. But over time it became like twitter where i felt like i should write down every though i had. And so i stopped. I also did not want to force myself to write something just because i wanted to write.

Anyhow, finding the right pen was very important. I discovered that i am a huge fan of gel pens and after trying dozens of them i landed on pentel energel. I found them to have the best glide and feel and the 0.7mm felt perfect to me. Though i found others with better pigment(black, of course, not blue!) the energel was just the best overall.

Also, finding the right diary was very hard. You need the right paper texture, thickness, size, number of pages. It is very personal thing and for me it was very hard to find what i was after.

Lastly, I got into fountain pens. Actually that might have been the initial reason to get into writing, and i found there is little difference between pens and tips and is mostly about the right ink.

After decades, i finally made up a proper signature, so that was great.

And yeah, i recommend it. Get into pens, paper, writing and whatnot. You can only gain from the experience.

Billionaires and ethnonationalist supremacists share a belief that they are "special" and entitled to do whatever they want because they are "better" and "more deserving". Doesn't matter the time period or the faction: European colonial invaders/separatists, Nazis, or Likud because almost every ideology based on supremacy tends to lead to war, repression, suffering, and/or mass death.

Thanks for the feedback, it helps me see things from a different perspective.

These are excellent questions, and you're absolutely right that they should be clear from the landing page. I'll work on fixing that.

Short answers:

1. Good point about asserts. When writing the benefits, I was targeting a broader audience (unittest users, people coming from other languages like JS), but the reality is most visitors are probably "pytest escapers" who already know pytest uses assert. I'll reorganize the selling points to focus on what actually differentiates Vedro.

2. The main philosophy is "all you need is functions and their compositions", no special decorators or dependency injection magic. But this is indeed missing from the index page. Will definitely add clear examples showing how to handle common fixture use cases with plain functions.

3. One diff example on the landing page clearly isn't enough. I'll add more comparisons. Since you hate pytest's diff output too, I'd love to hear what specifically bothers you about it, your pain points would be incredibly valuable for improving how I present Vedro's approach.

[…] is to be considered that genuine Gypsies have often been spoken of as "tinkers" (chaudronniers) on account of the occupation with which they have long been associated ; and that, although there is no known mention of "Gypsies" in the British Islands prior to the fifteenth century, there are many earlier references to "tinkers" or "tinklers," as they are called in Scotland. […] "Tinkler can be traced back to about the year 1200. Tinker and Tinkler were not uncommon titles at that time. […] All these seem to have had fixed abodes, and not to have been of the same itinerant class with which we now associate all tinkers, and which used to require the epithet 'wandering' to distinguish them." […] To the same purpose as the opinion expressed in this last sentence is Crofton's observation made elsewhere, that "all Gypsies may be pedlars, brasiers, or tinkers, but the reverse may not follow."

> Hard to tell. We could devaluate. That would help with both the debt situation and our exports. The UK is not doing that bad at all.

1. It is widely recognised, and irritates the poorer countries, that Germany and France benefit from the relatively weak Euro for their exports.

2. If you left the EU and obviously the Euro and devalued your currency, you end up with wild inflation. If there is anything a population hates, it is high inflation. Given your political situation in France currently, no government would last a year in that scenario.

3. Devaluing obviously causes bond rates to rocket, which means rolling over your current debt because extremely serious.

4. On top of that, mortgage rates rocket, people hate that too.

There is a reason countries don't just print money and devalue all the time. If it was that easy, everyone would do it.

It's a nice change of pace around here when people intentionally make themselves the butt of the joke by acting like extremely common phrases are somehow foreign to them. "Lived experience" immediately adds more detail and context to how they obtained their knowledge by explicitly referring to first hand involvement and direct experience rather than potentially from second hand sources or studying, but here you are making a smarmy reply pretending that it was somehow more confusing to the benefit of the rest of us who might take your attempt at quips as humorous. Thanks for the laugh!

It didn't have enough gold to pay its bonds, so it could either keep the integrity of the dollars intact while defaulting on the bonds, or keep the integrity of the bonds (as measured in dollars) intact while defaulting on the dollars. The latter option allowed it to last a while longer before anyone would notice.

This choice was made some decades before the official day on which the gold standard ended. By 1971, it had already printed dollars to pay its bonds and didn't have nearly enough gold for foreign countries to be able to withdraw all their gold.
Show HN: Valoris Research sifts AI papers to surface venture-grade startup ideas
by sumitchugh22 | 2025-10-02 07:51:56+00:00
Hi HN,

I built Valoris Research to solve a problem I kept running into: there’s a flood of brilliant AI research on arXiv every day, but very little of it makes the jump into real, venture-backable startup ideas.

Valoris Research is a daily feed that:

- Scans the latest arXiv AI papers

- Evaluates them for market potential, customer pain points, and venture readiness

- Publishes concise, human-readable venture ideas inspired by the most promising works

Think of it as a bridge between emerging academic research and practical innovation — built for founders, investors, and technologists looking for their next big idea.

I launched this as a side project a few weeks ago and have been shipping daily. I’d love feedback from the HN community — especially around:

- Usefulness of the venture idea format

- Gaps or improvements you’d want as a founder or investor

- Whether there are other research domains I should cover beyond AI

Happy to answer questions about how I evaluate research, pick ideas, or scale the pipeline.

— Sumit

> His books, many of which are annotated with margin comments,

I'm not saying that he did, but this along with being the right age to have read How to Read a Book by Mortimer J. Adler strongly suggest that he used that book to grasp a lot more of his books than most people can.

That book gives you a very good strategy for reading books that are beyond you normally. In the three years since I've read it I've managed to finish books that I couldn't read even when I was doing my PhD and it was my full time job to understand them.

The funny thing is that I only ran into that book when I was trying to figure out how to build knowledge graphs for complex documents using LLMs. Using multiple readings to create a summary of each chunk, then a graph of the connections between the chunks, then a glossary of all the terms and finally a critique of each chunk gave better than sota results for the documents I was working on.

> Was this intentional? Did they intentionally double the headcount?

Yes

>To what gain?

- reporting explosive growth

- launching a lot of initiatives, of which more than half of are probably shelved c. 2025. Seriously, peek into any company and see all the odd products they were announcing back then.

- to gain more of a global foothold. If you want to operate in a new country, you'll need to hire a lot of staff to manage compliance, run offices, work with local companies, etc.

- to have a lot of bodies to throw at a problem should they need it. Since hiring was basically "free" is was convinent to have talent on hold just in case.

- to poach, be it from competitors or from potential future competition. There's been reports of skilled hires who'd proceed to be on standby for quite a while. But paid very well. That's not something you do normally.

>Why would they deliberately give up their profits by doubling headcount just to layoff around 10% in aggregate?

That's the oversimplification of S174. They weren't losing much revenue because those labor costs would be balanced out from the taxes they didn't have to pay. It just cancels out.

Layoffs started quick once that ended. Remeber, they don't see layoffs as a "bad thing" as a business. The stock even bumps up a tiny bit back on 2022/2023 over layoff news. Something about "being responsible" or some drek.

S174 will be back next year, but I think there's multiple other issues that mean the market won't quickly bounce back.

> all palestinians that are israeli citizens have exactly same rights under law.

No, this is totally false. There have been many discriminatory laws passed against non-Jews and Arabs in the past couple of years. And then there's the yellow vs. green vehicle number plate thing.

I'm sure most people mask, but the difference between neurotypical and neurodivergent people is how much they mask, and when.

For instance, like many people on the spectrum, I feel discomfort making any form of direct eye contact. When I don't have a lot of mental energy, this discomfort can become quite intense, to the point that maintaining normal eye contact takes up so much mental effort that I can't listen to what someone is saying anymore.

I don't exactly have the "normal" experience to compare with, but I don't believe most people experience that. I've learned the hard way that people don't really appreciate it when you stare at the floor during the entire conversation, so forcing myself to make eye contact has become more automatic over the years, but it adds just a little bit of extra effort on top of what everyone else is feeling.

Sometimes, it's also other tiny issues. Deviations from how things "should be" can trigger an irrational feeling of upsetting. As a kid I remember crying about a door being painted, or the class using a different set of stairs to the normal route because deep down it felt extremely wrong. Even in my teens, having fries on a Tuesday was something I sometimes needed to recover from. I've learned to dismiss/ignore/crop up those irrational feelings, but sometimes they can sneak up on you and become quite taxing. The worst part, in my opinion, is how the mental impact remains despite knowing how absolutely bonkers those feelings are.

I believe I'm not affected as strongly by my autism as some other unfortunate souls are, because people seem somewhat surprised when they learn about stuff like that. I can only imagine how stressful their daily lives must be.

Small companies should go for the likes of Hetzner/OVH, which is still 10+ times cheaper than AWS.

AWS is for anyone with a fear of committing to a particular amount of resource use, but once you've tried both and realised the price and performance differential, you realize you can easily way overcommit and still come out ahead, so it's not actually that scary. Plus, nobody's stopping you from continuing to spin up EC2s when your real servers are fully utilized.

For some nuts and bolts, I myself struggle with it, almost to the point of giving up.

But what the article misses: We can just rearrange our environment to make it easy to interact with by robots. There might be only standardized nuts and bolts, with IDs imprinted so the robots know exactly how to apply them. Dishes might come in certified robot-known dimensions, or with invisible marks on where to best grip them. Matchsticks might be replaced by standardized gas lighters. Maybe robot companies will even sell those themselves.

Care to ellaborate? Not shitting on libavcodec here, I would also guess it just beats a new project on raw performance.

But according to the repo, this project also uses both slice and frame multi-threading (as does ffmpeg, with all the tradeoffs).

And SIMD usage is basically table-stakes, and libavcodec uses SIMD all over the place?

If requests are already hitting your servers, it’s too late — you’re burning CPU and bandwidth before rejecting. I built Rately to solve this at the edge: set limits by user, IP, or plan (e.g. free = 1k/day, pro = 1M/month) and return 429s before traffic reaches your infra. Keeps apps simple and protects backend capacity.

It doesn't have to be a direct stand-in. It's mentioned in the article that people suspect McCarthy of reveling in the violence in his novels. Whether he does or does not he would certainly have been aware of that perception. Judge Holden as a character embodies many distasteful qualities of mankind, it would make sense that the qualities he embodies the most distinctly are the ones McCarthy sees in himself.

AI will help people harden and rationalize their cognitive dissonance to ignore millions of civilians being deliberately starved mere miles away on purpose by sweeping it under the rug to instead discuss the weather and random technology flavor-of-the-day. It's so tonedeaf that clanging pots and pans in front of their faces has no effect.

> I think it's because it did kind of used to mean that. It described people that couldn't mask, couldn't totally function in society, couldn't have the kind of job depicted in the Autism Simulator.

If you mean "Autism", that might be true. But I don't think "Asperger's" meant that. So we might have taken a step backwards there.

So, since people will play the games anyway, companies should design the office politics in such a way that the company makes more money, and therefore it can afford to pay the team members more money too. Everyone in the company is therefore better off. Did I get that right?

How would such a positive-sum game look? I'm lacking imagination because I've never worked in an environment with such a positive game.

Columnar storage is great because a complex nested schema can be decomposed into its leaf values and stored as primitives. You can directly access leaf values, avoiding a ton of IO and parsing. Note that all these formats are actually partitioned into groups of rows at the top level.

One big win here is that it's possible to get Apache Arrow buffers directly from the data pages - either by using the provided WASM or bringing a native decoder.

In Parquet this is currently very complicated. Parquet uses the Dremel encoding which stores primitive values alongside two streams of integers (repetition and definition levels) that drive a state machine constructed from the schema to reconstruct records. Even getting those integer streams is hard - Parquet has settled on “RLE” which is a mixture of bit-packing and run-length encoding and the reference implementation uses 74,000 lines of generated code just for the bit-packing part.

So to get Arrow buffers from Parquet is a significant amount of work. F3 should make this much easier and future-proof.

One of the suggested wins here is random access to metadata. When using GeoParquet I index the metadata in SQLite, otherwise it would take about 10 minutes as opposed to a few milliseconds to run a spatial query on e.g. Overture Maps - I'd need to parse the footer of ~500 files meaning ~150MB of Thrift would need to be parsed and queried.

However the choice of Google's Flatbuffers is an odd one. Memory safety with FlatBuffers is a known problem [1]. I seriously doubt that generated code that must mitigate these threats will show any real-world performance benefits. Actually - why not just embed a SQLite database?

>I think i have to repeat: You didnt criticise UBI but gov. abuse of power. Which could already reach deep down into everyones life in plenty of other domains besides UBI. Is any kind of state service by definition bad now?

Ah, here's the difference: You're considering UBI based on the idea that "if governments behave well and to the interest of the people, UBI is fine too". I'm starting from real world governments and their real world behaviors, not fantasy.

In the real world, total control of hundreds of millions of people livelihood via a standardized UBI scheme, is a huge additional government tool for abuse. And the extra reach and power it gives government, and the constant dependency it adds, it's a totally new game.

And that's not compared to some dictatorship or "emergency powers" (which duh!, can be more abusive), UBI would be a steadily available tool for low-burning abuse and subtle control.

>Heck, we could even unnecessarily complicate the issue by putting the UBI responsibility on an extra governmental body, neither state nor private

Ah, yes, like the FED for example. Controlled by government but also unaccountable when it's more convenient to those in power.

>Your pessimistic stance on goverments hinders you from accurately describing problems with it, which means you cant articulate constructive solutions too

Actually my pragmatic stance on governments ("pessimistic" and "optimistic" stances are for people unconnected with reality, of course the latter way more so), which means I'm not in favor in giving them huge guns to extend their power more, especially given their track record.

But if you look at the world around you, and think "it's pretty neat", more power to you.

Saying that RAG alone is complex and should be superseded by agentic search is a bit weak. Agentic search makes more sense when your pipeline becomes more complicated: RAG+MCP+Client calls, it is then when you can see that LLM starts behaving erratically and cannot answer the question well. You then want better control over streams of content and intents which could be solved by smaller agents looping over the data.

After building a few RAG based apps I was curious to try the ClaudeCode based approach that is mentioned by the author. So I built a python service that exposes ripgrep to a rest api: https://github.com/masterkram/jaguar

This makes it possible to quickly deploy this on coolify and quickly build an agent that can use ripgrep on any of your uploaded files.
