> Most of the tests are BS too.

Only if you don't constrain the tests. If you use agents adversarially in generating test cases, tests and review of results, you can get robust and tight test cases.

Unless you're in research, most of what we do in our day jobs is boilerplate. Using these tools is not yet foolproof, but with some experience and experimentation you can get excellent results.

> I would suggest that something like "Skibidi Toilet" is just this generation's badger-badger-mushroom

Beyond the first minute or two, I'd not class Skibidi Toilet as any kind of humor. It's a serialized silent (late-era-style silent with synced foley but no dialog) sci-fi action war epic told without intertitles.

Uhh… The fact that there's no Archlinux package for a given language doesn't imply there's no tree-sitter support (official or 3rd-party) for that language? See e.g. the very long list of languages on https://github.com/Goldziher/tree-sitter-language-pack , which does include R, YAML, Golang, and many more.

I've been trying my hands at implementing an emacs package for inline completions with this. I have it mostly working and performance is good enough but I haven't been blown away by the quality of its suggestions unfortunately. Which I guess is expected from a 1.5B model.

I'd love to see them making a larger model in the 10-20b range maybe? I know most people wouldn't be able to run that on their machines, but some could.

Running on ollama locally on NVIDIA Spark GB10. Tried it also with vLLM. Pretty fast.

Thanks for the feedback.

AI agents are the pull right now to why version control is needed outside of software engineering.

The mistake in the blog post is triggering comparisons to git, which leads to “why is this better/different than git?”.

If you have a custom binary file, you can write a plugin for it! :)

Lix runs on top of a SQL database because we initially built lix on top of git but needed:

- database semantics (transactions, acid, etc.)

- SQL to express history queries (diffing arbitrary file formats cant be solved with a simple diff() API)

> When you store a value into memory, the register renamer does nothing, because you do not attempt to modify any register.

you are of course correct about everything. But the extreme pendant in me can't avoid pointing out that there are in fact a few mainstream CPUs[1] that can rename memory to physical registers, at least in some cases. This is done explicitly to mitigate the cost of spilling. edit: this is different from the store-forwarding optimization you mentioned.

As divided as the US is right now, there's a bunch of things like this that every American seems to agree on without even realizing that it's not the same in most of the world.

For example, "work ethic". Correct me if I'm wrong, but you could write "worked very hard every day" on someone's tombstone, and almost every American seeing it, regardless of politics, will think "That was a good person". Someone to look up to.

Not "did good work", not "their work helped many people", definitely not "lived well". Even "was very productive" sounds too suspicious - being productive is great and all, but a productive person might be doing 10h worth of work in 5h and then call it a day, and that's just unacceptable, so that's not going on your tombstone either.

Just... work hard. The protestant ideal. Going on vacation and being too sick to work is literally the same thing, because it stops you from working hard.
by bsoles | 2026-01-22 15:33:00+00:00
Sure. There are many examples of data scientists attempting to use complex Machine Learning and Deep Learning models to predict machine (bearings, gears, etc.) failures from vibration data, where a simple Fourier Transform (FFT) provides a lot more insight and predictive powers about the same problem.

However, spectrum analysis is not something that data scientists learn at school, yet every mechanical/electronics engineer working in the field knows about it. So, without an expertise in a particular field, data scientists often reach for a big hammer, when more specialized tools exist and are known to the experts in the field.

Agreed, optimism/pessimism is just about our disposition to the world as we perceive it (ie. glass half full or half empty). It is orthogonal to understanding and prediction. A perfect Buddhist is neither an optimist or pessimist but can still be better or worse at predicting the future.

I do think pessimists, especially of the depressive variety generally do not get rich. The reason is that getting rich is hard, everyone nominally wants it, so it’s highly competitive and there are no easy paths. To find a path generally you have to take an action that almost by definition is low probability of success. You don’t have to be a beaming cheerleader to make this happen, but being an eyore is most likely disqualifying.

> There is also a genuine argument to be had as to, for example, whether the practice contributes towards antimicrobial resistance.

The chlorination is less in question here compared to the extreme overuse of antibiotics in animal farming in America. But it is fair to be skeptical of America's chlorination approach due to the increased danger of animal-human disease crossovers. Poor sanitation can lead to a lot of elevated work risks for employees.
Show HN: A Chrome extension that dings when ChatGPT is done "thinking"
by mooball | 2026-01-22 15:33:06+00:00
I got tired of waiting on ChatGPT to finish "cooking", so I made an extension that plays a sound when it's done generating.

Originally I just shared with friends/family but I'm starting to get random reviews like: "love the tool, hate the sound."

https://github.com/rumblelab/chatdinger
https://go.chatdinger.com/hn

I'm curious, what sound do you think the AI should make when it's done cooking? And why the heck hasn't openAI made this native yet?

At the end of November, I shared a questionnaire to discover what the community thinks about the state of Laravel packages today.

I wanted to focus on the real-world pain points developers face.

To ensure I got busy developers to respond, I kept it short, under 3 minutes on average.

Without an established audience, I managed to reach around 200 responses.

This article illustrates what the community had to say.

> large expansion of corn acreage

Corn acres have expanded, but the same is also true of other crops. Given corn's role in the crop rotation, it stands to reason that when other crops expand, corn comes with it. There are a lot more mouths to feed nowadays. The world's population has grown by approximately 30% since the last change in ethanol policy.

> that corresponds to ethanol policy.

The ethanol subsidy in the last policy change ended in 2011, yet, as you point out, corn acres have continued to expand, which seems contrary to what you are trying to suggest. What specific correspondence are you finding?

Yuck, this is going to really harm scientific research.

There is already a problem with papers falsifying data/samples/etc, LLMs being able to put out plausible papers is just going to make it worse.

On the bright side, maybe this will get the scientific community and science journalists to finally take reproducibility more seriously. I'd love to see future reporting that instead of saying "Research finds amazing chemical x which does y" you see "Researcher reproduces amazing results for chemical x which does y. First discovered by z".

That might be part of the equation, but for many it’s a strong gut reaction to having the work of themselves and others taken without consent, turned into the visual equivalent of pink slime and press-formed into other shapes, and sold as a service. It just feels wrong. Even I get a little squeamish thinking about it, and I only do art in a minor/hobby capacity — it’s something I’ve put time into, but it doesn’t pay my bills.

If training were purely ethical, the creative community probably still wouldn’t love generative AI, but it probably wouldn’t hate it nearly as much either. It’s the cavalier attitude towards violation of consent for the sake of profit that really seals the deal.

i’ve noticed the issue with tmux more than with specific terminals.

basically, the rapid replay of the entire conversation history (the CC bug) somehow interacts destructively with something in tmux, causing it to be 10 times worse. The “flicker” becomes a multi-second delay while I wait twiddling my thumbs…

i’ve seen this in every terminal, including ghostty… as nice as ghostty is, expecting everyone to use it is kinda meh (at least support Wezterm too, lol)

Other people might point to more specific tells, but instead I'll reference https://zanlib.dev/blog/reliable-signals-of-honest-intent/, which says that you can tell mainly because of the subconscious uncanny valley effect, and then you start noticing the tells afterwards.

Here, there's a handful of specific phrases or patterns, but mostly it's just that the writing feels very AI-written (or at least AI-edited). It's all just slightly too perfect, like someone's trying to write the perfect LinkedIn post but are slightly too good at it? It's purely gut feeling, but I don't think that means that it's wrong (although equally it doesn't mean that it's proven beyond reasonable doubt either, so I'm not going to start any witch hunts about it).

Yes, I do not see any source of financial gain that could motivate them for this, because both MuPDF and Ghostscript are free.

MuPDF is an excellent PDF reader, the fastest that I have ever tested. There are plenty of big PDF files where most other readers are annoyingly slow.

It is my default PDF and EPUB reader, except that in very rare cases I encounter PDF files which MuPDF cannot understand, when I use other PDF readers (e.g. Okular).

> Torvalds was right, code maintenance is going to be a headache thanks to LLMs.

I know someone in a senior engineering position at Epic who does nothing but clean up PR's from their off-shored Ukrainian sweat shop coders handing in AI slop because all they need to do is close a ticket to get paid. They wind up rewriting half or more of it. Epic doesn't seem to care so long as this "solution" works and saves them money by paying a few really smart people to code janitor until hopefully all of them can be replaced by LLMs.

I skimmed the "slop" collection they maintain that was posted here yesterday, and even under those HackerOne submissions, Daniel was perfectly reasonable and respectful.

It is entirely possible I merely chanced upon his highlights, but this announcement to me really just signifies a final straw breaking than anything else. His historical conduct is all public and speaks for itself. I wish I had the patience and perseverance he does, and I wish he didn't need it.

They were committing various felonies in the first season, if I recall. It couldn’t have been more clear that these characters are bad people who will do almost anything to get what they want. The humor lies in the arbitrary and inconsistent boundaries they set for themselves and each other.

Department Q is a weird one because it goes with the trope of the acerbic hyper-competent guy, but then… actually, I don’t recall, is he actually incompetent? Or does he just not quite live up to his over-confidence.

Also it is sometimes hard with these detective shows because the screenwriters might want a character to be hyper-competent, but they are people too, limited in their ability to portray super-competent abilities. This can result in characters lucking their way into clues.

Your response is in the same category. Imagine ignoring the social media posts by Mossad stating they were on the ground in Iran during this. The former head of the Trump CIA posing nonsense. Ignore Trump stating he would bomb Iran in response.

Western colonialist countries want to get in on invading Iran stealing its oil and partitioning the country.

There are still plans to try and do so. If the US moves carrier groups into the region, then I’m sure they will endeavor to install an Israeli puppet like the former Shah’s aging son WHO WAS INSTALLED BY THE CIA & MI6 over oil.

This is like the difference between an orange and fruit juice. You can squeeze an orange to extract its juices, but that is not the only thing you can do with it, nor is it the only way to make fruit juice.

I use tree-sitter for developing a custom programming language, you still need an extra step to get from CST to AST, but the overall DevEx is much quicker that hand-rolling the parser.

What is the point of using a generic compression algorithm in a file format? Does this actually get you much over turning on filesystem and transport compression, which can transparently swap the generic algorithm (e.g. my files are already all zstd compressed. HTTP can already negotiate brotli or zstd)? If it's not tuned to the application, it seems like it's better to leave it uncompressed and let the user decide what they want (e.g. people noting tradeoffs with bro vs zstd; let the person who has to live with the tradeoff decide it, not the original file author).
Show HN: Accent AI – real-time speech clarity drills (pronunciation,stress etc.)
by wabiosdev | 2026-01-22 15:37:23+00:00
Hi HN — I built Accent AI, an iOS/Android pronunciation + public speaking coach.

What it does:
- Listen to short prompts and give feedback on pronunciation, stress/intonation, pacing, and breathing.
- A “meeting mode” style practice for clearer speech under pressure (stage anxiety / speaking confidence).

Why I built it:
I work with many non-native English speakers who can write English well but aren’t understood quickly in calls/interviews. I wanted fast, targeted drills that focus on clarity (not just vocabulary).

How it works (happy to go deep in comments):
- [Briefly describe your pipeline/model choices, scoring method, and what’s computed on-device vs server]
- Privacy: [What audio is stored? for how long? opt-out?]
- Platforms: iOS + Android.

Pricing:
For the next 20 hours I’m running a one-time promo: lifetime is free on iOS and $0.50 on Android. After that it returns to normal pricing

(Using Gemini btw)

I’d love blunt feedback on accuracy and what would make this genuinely useful in real meetings/interviews.

Pedanticism is insisting that the headline is correct. Pedantically, the headline is correct, Europe did suspend the deal.

However, the headline implies that Europe broke the deal. That implication is incorrect, making the headline wrong in the non-pedantic reading.

The US broke the deal, and this story is simply about Europe acknowledging that fact.

I measure what I do by output.

Just about a week ago I launched a 100% AI generated project that shortcircuits a bunch of manual tasks. What before took 3+ weeks of manual work to produce, now takes us 1-2 days to verify instead. It generates revenue. It solved the problem of taking a workflow that was barely profitable and cutting costs by more than 90%. Half the remaining time is ongoing process optimization - we hope to fully automate away the reaming 1-2 days.

This was a problem that wasn't even tractable without AI, and there's no "explosion of AI generated code".

I fully agree that some places will drown in a deluge of AI generated code of poor quality, but that is an operator fault. In fact, one of my current clients retained me specifically to clean up after someone who dove head first into "AI first" without an understanding of proper guardrails.

> If Europe is a big customer for Chinese exports, and Russia is antagonizing, it seems like China would have an incentive to put pressure on Russia.

China wants Russia to at least keep the Ukraine war going, if not eventually win the darn thing. Russia winning (or getting away with an armistice that lets them keep Crimea and Donbas) means a precedence China has for a land-grab of its own - obviously Taiwan, but other countries in its "sphere of influence" have seen hostilities for years, from land grabs [1] to overfishing [2], not to mention the border dispute with India.

And as long as we are distracted with Israel/Palestine or Ukraine/Russia, China has free rein to do whatever they want.

That's how I see Charlie Brown, as do many of my friends. We frequently use the "CB missing the football" as an analogy for the Democratic Party - over the past several decades years, the party has been a long series of swing-and-misses (notably their ability to win the popular vote but lose an election, and even more their inability to beat Trump, twice).

Isn't design thinking just... thinking? There may be different design methodologies you apply in different domains (e.g. civil, aeronautics, automotive, electronics, software), but once you abstract that away, what you get is thinking. I once attended a design thinking workshop many years ago, and no one there was able to adequately explain what design thinking was, except by means of jargon, metaphor, or example. My understanding of the subject has not advanced much further in the intervening years.

There is not a single example of a multiethnic or culturally diverse empire or state that was successful after the rise of nation-states at the end of the 19th century.

All of them crumbled either peacefully or in bloody wars.

Why do you think such a bureaucratic monster that no one really wants would be an exception?

Maybe we can try it again in the 24th century, when the humans evolve enough, but for now, your best bet for a successful country is either an ethnonational or religion-national state.

Show HN: Borr AI – An open-source telemetry for retail
by matthewduff | 2026-01-22 15:38:58+00:00
Hi HN, we’re the creators of Borr AI. We’ve open-sourced a pipeline designed to turn physical retail environments into structured, auditable data.

In digital products, we have high-fidelity analytics for every user interaction. In physical retail, that data is usually locked inside proprietary black boxes or grainy CCTV. Borr is a self-hosted platform that fuses stereo vision and weight telemetry to create a "computational truth" for physical spaces.

The Use Cases:

Forensic Theft Detection

Instead of just recording video, Borr generates a hashed "evidence packet." It correlates 3D proximity events with weight sensor deltas to provide a mathematical certainty estimate of an interaction, making it auditable for security and court admissibility.

We provide the primitives to track customer journeys in 3D without cloud facial recognition. You can analyze shelf "dwell times," product interaction rates, and heatmaps with millimeter precision using our DLT (Direct Linear Transform) solvers.

Checkout-Free Retail: The system could be expanded to track "identity custody" across camera blind spots using a BIP solver. This allows developers to build "Just Walk Out" experiences where transactions are validated by the fusion of vision and weight data.

Technical Stack:

Dual-camera triangulation using YOLOv8-pose. Probabilistic correlation of weight sensors (0.7 weight) and vision events (0.3 weight). Locally-Aware Transformers (LATransformer) to maintain persistent user IDs without biometrics.
