That's an interesting interpretation of open source.
WhyIsItAlwaysHN··on SQL patterns I use to catch transaction fraud
The article states that the particular item is a clear sign of fraud. If that was true, then it should be treated in a special manner. A more paranoid bank could enforce it without adhering to this guidance of multi-factor detection.

It isn't though, so balancing it with other rules is fine.

Exactly, hopefully this is not an autoblock in the future.

Tolls, revenue taxes, ever stricter rules that cause tickets despite technology getting better.
WhyIsItAlwaysHN··on New research suggests people can communicate and practice skills while dreaming
My experience was with building a new computer. I had gotten all of the parts needed to completely upgrade my pc, keeping only the case.After installing all of them, the computer refused to boot and just showed a generic error with a blinking light. I tried multiple things to troubleshoot like taking out each ram stick, different hdd, reseating cables, different hdd, change to internal gpu, nothing worked.

Then I fell asleep and when I woke up in the morning, I had a very strong feeling that the issue was definitely the memory and I had to move the ram to the set of slots for the other channel. And that was the issue, broken slots.

What's impressive is not that it worked, but that after waking up I had no doubt that was the problem, even though practically I couldn't conciously identify why I was so confident about it.

WhyIsItAlwaysHN··on Show HN: I made a YouTube search form with advanced filters
Maybe this is an unpopular opinion, but this seems to just create the search string in the url, aka youtube search already supports these features.

If people were really looking for exact title search they could write "term".

It is definitely true that youtube's search is optimized for engagement, but going through a separate ui just to search it seems a bit redundant, especially if after I click search I have ti deal with youtube's UI.

WhyIsItAlwaysHN··on Cross-Model Void Convergence: GPT-5.2 and Claude Opus 4.6 Deterministic Silence
This result sounds very unsurprising at this point of having models that can reliably use tools.

Some part of RL training must focus on the length of responses. I would also guess that Anthropic and OpenAI have an incentive to optimize response length without sacrificing user satisfaction/retention.

For example, I would be more satisfied if claude code didn't execute a side-effect free script that produces no output. Embodying the concept of silence is semantically close to predicting the output of an empty program, so it's more efficient to say nothing.

Even in the past though similar tests gave output like says nothing. I think that points more towards optimizing for less tokens than the implied special understanding by the latest models.

WhyIsItAlwaysHN··on I tried to replace myself with ChatGPT in my English class
Ideally it's not weeding out but distributing into education paths which fit every student.

From my experience studying electrical and computer engineering, I definitely prefer that they chose to put hard electrical engineering courses in the first semesters because I knew immediately not to focus on them because I didn't like them.

WhyIsItAlwaysHN··on I tried to replace myself with ChatGPT in my English class
They will not choose to write it. Would you work on something consistently if nobody cared about it?

There needs to be a reward for doing essays. That reward can be emotional eg. "the teacher I respect liked my essay" or "my essay was read in class" or "the teacher gives feedback that makes me feel a sense of growth". In that case, maybe kids will do it.

However, I think it's hard for a teacher to inspire respect to a classroom and the difficulty scales with the number of people in the class, so grades are used as a hack.

You might want to add a simple description of each company. I don't know half of them and in this dopamine shot optimized format, I don't really have the patience to research every one of them in a different tab.
WhyIsItAlwaysHN··on We investigated Amsterdam's attempt to build a 'fair' fraud detection model
Some groups will be more disadvantaged than others by being investigated. For example for welfare, I expect fraudsters to have more money to support themselves or less people to support (unless the criteria for welfare is something unexpected). So I'd say that there also needs to be more protections than just providing money.

Nevertheless the idea of giving money is still good imo, because it also incentivizes the fraud detection becoming more efficient, since mistakes now cost more. Unfortunately I have a feeling people might game that to get more money by triggering false investigations.

WhyIsItAlwaysHN··on LLMs are cheap
What I was saying is that you wouldn't use a raw LLM (so 506 tokens to get an answer). You would use it with web search so you can get the links.

The LLM has to read the websites to answer you so that significantly increases the token count, since it has to include them in its input.

WhyIsItAlwaysHN··on LLMs are cheap
But that was my point, then you need to include the entire websites in the context and it won't be 506 tokens per question. It will be thousands
WhyIsItAlwaysHN··on LLMs are cheap
There's something I don't get in this analysis.

The queries for the LLM which were used to estimate costs don't make a lot of sense for LLMs.

You would not ask an LLM to tell you the baggage size for a flight because there might be a rule added a week ago that changes this or the LLM might hallucinate the numbers.

You would ask an LLM with web search included so it can find sources and ground the answer. This applies to any question where you need factual data, otherwise it's like asking a random stranger on the street about things that can cost money.Then the token size balloons because the LLM needs to add entire websites to its context.

If you are not looking for a grounded answer, you might be doing something more creative, like writing a text. In that case, you might be iterating on the text where the entire discussion is sent multiple times as context so you can get the answer. There might be caching/batching etc but still the tokens required grow very fast.

In summary, I think the token estimates are likely quite off. But not to be all critical, I think it was a very informative post and in the end without real world consumption data, it's hard to estimate these things.

WhyIsItAlwaysHN··on Musk-Trump dispute includes threats to SpaceX contracts
Good point, and much harder to challenge. If the majority is against an authoritarian there's protests and sabotage of social structures. If the majority oppresses a fringe group, it's often socially encouraged
WhyIsItAlwaysHN··on AI makes the humanities more important, but also weirder
What would you need to tackle this assignment?

I think you're right to complain about the design of the question. It used Google's disadvantage in that it couldn't process visual information to add difficulty to the task.

However I'm pretty sure there's many of these challenges in an average stem subject. An example would be information dense diagrams which describe some chemical process.

I'm genuinely curious to understand how someone manages to understand these without sight. On my side, I can barely visualize so it was always extremely hard to decipher them and even worse remember them.

WhyIsItAlwaysHN··on Show HN: I compressed 10k PDFs into a 1.4GB video for LLM memory
Is the probability of lost data zero across eg. millions of documents?

I see there's a 30% redundancy per document, but I'm not sure every frame in a h265 file is guaranteed to have more than 70% of a qr code being readable. And if it's not readable, then that could mean losing an entire chunk of data.

I'd definitely calculate the probability of losing data if storing text with a lossy compression.

WhyIsItAlwaysHN··on Show HN: I compressed 10k PDFs into a 1.4GB video for LLM memory
Is this more efficient than putting all of that in say a 7z archive?

I'd expect video frames to be maximally efficient if you sorted the chunks by image similarity somehow.

Also isn't there a risk of losing data by doing this since for example h.265 is lossy?
