JacobiX··on What will our economic future look like?
Air travel is a good counterexample here: technology made airlines far more productive, but much of the gain went into lower staffing, higher throughput, and cost cutting not a better passenger experience
JacobiX··on What will our economic future look like?
> As the nurse incorporates AI into her job, the nurse is able to oversee and accomplish more. She can spend more time talking with patients and helping them understand diagnoses. Productivity increases.

This feels economically naïve.. If AI lets one nurse do the work that previously required two, the default pressure in a cost-driven system is not "great, now nurses can spend twice as long with patients" It is "great, now we can run the same operation with fewer nurses"

JacobiX··on Statement from Dario Amodei on our discussions with the Department of War
>> We chose to forgo several hundred million dollars in revenue to cut off the use of Claude by firms linked to the Chinese Communist Party

You can’t choose to work with OFAC-designated entities.. there are very serious criminal penalties. Therefore, this statement is somewhat misleading in my opinion.

JacobiX··on Show HN: ShapedQL – A SQL engine for multi-stage ranking and RAG
>> Apply diversity logic so your Agent/User doesn’t see 10 nearly identical results

On Instagram this is a good thing, but here the example is hotel and flight search, where a more deterministic result is preferable.

In the retrieve → filter stage, using predicate pushdown may be more performant: first filter using hard constraints, then apply hybrid search ?

JacobiX··on Is the golden age of Indie software over?
>> it is getting harder for small software vendors

I think maybe this trend will continue and not specifically for indie developers, but for all software vendors. If AI becomes capable of producing genuinely highquality software, competition will intensify, and the industry will start to resemble the music industry. Alternatively, AI may continue to generate software that is not necessarily high quality but is largely indistinguishable from competing products; in that case, the market for lemons dynamic will apply. In either scenario, the value of software will decline...

JacobiX··on DeepSeekMath-V2: Towards Self-Verifiable Mathematical Reasoning [pdf]
I think that mathematical proofs, as they are actually written, rely on natural language and on a large amount of implicit shared knowledge. They are not formalized in the Principia Mathematica sense, and they are even further from the syntax required by modern theorem provers. Even the most rigorous proofs such as those in Bourbaki are not directly translatable into a fully formal system.
JacobiX··on Technical Deflation
In the end, the article says:

> writing functioning application code has grown easier thanks to AI.

> It's getting easier and easier for startups to do stuff.

> Another answer might be to use the fact that software is becoming free and disposable to your advantage.

For me, the logical conclusion here is: don't build a software startup!

JacobiX··on Gemini 3
Yes; they nailed the root case but the implementation is not 100% correct
JacobiX··on Gemini 3
Tested it on a bug that Claude and ChatGPT Pro struggled with, it nailed it, but only solved it partially (it was about matching data using a bipartite graph). Another task was optimizing a complex SQL script: the deep-thinking mode provided a genuinely nuanced approach using indexes and rewriting parts of the query. ChatGPT Pro had identified more or less the same issues. For frontend development, I think it’s obvious that it’s more powerful than Claude Code, at least in my tests, the UIs it produces are just better. For backend development, it’s good, but I noticed that in Java specifically, it often outputs code that doesn’t compile on the first try, unlike Claude.
JacobiX··on Disrupting the first reported AI-orchestrated cyber espionage campaign
I have the feeling that we are still in the early stages of AI adoption, where regulation hasnt fully caught up yet. I can imagine a future where LLMs sit behind KYC identification and automatically report any suspicious user activity to the authorities... I just hope we won’t someday look back on this period with nostalgia :)
JacobiX··on Why JPEGs still rule the web (2024)
MozJPEG, Guetzli and also Jpegli
JacobiX··on Why JPEGs still rule the web (2024)
I loved the article, but it overlooks one important point: although the JPEG format is frozen, encoders are still evolving ! Advances such as smarter quantization, better perceptual models, and higher-precision maths enables us achieve higher compression ratios while sticking to a format that's supported everywhere :)
JacobiX··on Vacheron Constantin breaks the world record for most complicated wristwatch
What I like about mechanical watches is that, having survived a near-death experience when quartz watches were introduced, they’ve evolved into a completely different kind of product. It’s fascinating that, unlike most other businesses and products, people don’t buy them for their utility, and the less automated their production process, the better. Brands like A. Lange & Söhne even pride themselves on assembling their movements twice.

When inefficiency and craftsmanship are considered features rather than flaws, you have an industry that won’t easily be replaced by AI or robots.

JacobiX··on Apache ECharts
In a quick web demo, this library was the only one that could handle interactive viewing and manipulation of a very large graph using its GraphGL component ! I don’t think it's a well-known visualization library, but it's quite interesting ...
JacobiX··on A university president makes a case against cowardice
Not sure if Michael Roth is related to Philip Roth, but it somehow reminds me of American Pastoral and that era of protests against the Vietnam War and its aftermath. I'm not entirely sure how those demonstrations compare to the ones we’re seeing today, but the parallels are striking
JacobiX··on Benchmarking RSA Key Generation
It is fascinating (to me at least) that almost all RSA implementations rely on a probabilistic primality test, even though the probability of picking a pseudoprime is extremely small.
JacobiX··on Show HN: Squey, an open-source GPU-accelerated data visualization software
Thank you, I'll look into it more closely, fortunately it builds using CMake / Clang, and cross-platform libs ... might be possible to port it to MacOS after some tweaks.
JacobiX··on Show HN: Squey, an open-source GPU-accelerated data visualization software
Impressive project, judging by commits and features, it's clear that significant effort has been poured into this :) Unfortunately, there's no specific MacOS installation method provided, unsure if buildable from source ?
JacobiX··on Ask HN: What's the "best" book you've ever read?
I second this... to this day, I am in awe! Such a profound and readable book in the same time. Each character lives within me, and in many situations, one of them emerges :)

As Nabokov said, it is the supreme masterpiece of 19th-century prose.

JacobiX··on DuckDB Isn't Just Fast
In my experience, recent versions work well for out-of-core computation (I use it frequently). What is the size of the Parquet file that you are using? - I can't find the details in you previous comments.
JacobiX··on GPT-4.5 or GPT-5 being tested on LMSYS?
The model provides verbose answers even when I asked for more succinct ones. It still struggles with arithmetic (for example, it incorrectly stated "7739 % 23 = 339 exactly, making 23 a divisor"). When tested with questions in French, the responses were very similar to those of GPT-4. It is far better in knowledge based questions, I've asked this difficult one (it is not 100% correct but better than other LLMs) :

In Anna Karenina what does it mean: most of us prefer the company of Claras ?

JacobiX··on You are what you read, even if you don't always remember it
I agree with you, maybe books are not the ideal format for acquiring knowledge.

I read a lot of fiction books, mainly classics for pleasure. And what I found unique is that only in books I have access to the interior monologue of the characters, their thoughts, and on some occasions, direct access to their "stream of consciousness".

I love it, and I discovered that some characters (but in reality it's the authors) have a similar process of thought, and some others do not, and notice and sense things differently ...

JacobiX··on You are what you read, even if you don't always remember it
I find this tale quite interesting. Could you please point me to its origin or name?
JacobiX··on Apple has reportedly acquired Datakalab
One interesting coincidence is that the CEO worked previously at a startup that was also acquired by Apple (Emotient)
JacobiX··on The Pentagon's Silicon Valley Problem
Not sure why you consider those countries as ennemies (or semi-enemy) ?

For example, Jordan has maintained a position as a key major non-NATO ally of the United States within the Middle East (since 1996).

Also starting from 1989, both Egypt and Israel became major non-NATO allies of the US.

JacobiX··on The Pentagon's Silicon Valley Problem
From the same report, "U.S. Foreign Assistance to the Middle East": Israel has been the largest cumulative recipient of U.S. foreign assistance since World War II, receiving $158 billion. Jordan for example received $26.4 billion from 1951 to 2020.

>> Similarly with lifting sanctions on Iran, which resulted in giving them $10B.

In the case of Iran, it was not a matter of receiving $10 billion in aid, but rather the release of $10 billion of Iranian funds that had been frozen.

JacobiX··on USB hubs, printers, Java, and more seemingly broken by macOS 14.4 update
I've also updated my M1 Pro to macOS 14.4 and use Java (versions 21 and 17) daily with IntelliJ IDEA without encountering any issues so far even when using debuggers and profilers. Not sure how to explain it !
JacobiX··on Bruno: Fast and Git-friendly open-source API client (Postman alternative)
Same here regarding Insomnia: all my requests have disappeared. I was searching for an alternative, and this is a godsend :) somehow I missed it when searching for alternatives.
JacobiX··on Source-available Rust-based RAG
I find it difficult locate the core search features ... please correct me if I'm mistaken, but it appears that the search feature is a wrapper built on top of Qdrant ?
JacobiX··on Sweden Is a NATO Member
I think that NATO was founded after World War II, largely due to British efforts to contain the Soviet Union and its influence in Europe ?
