1. Nobody needs an app for this. People who engage in social intercourse are (likely) already rejecting people on a regular enough basis to feel bad about it.

2. The idea sounds really fun to people who enjoy being prejudiced over other people, and literal hell for anyone who is objectified for individual traits they express or possess. You are essentially describing the opposite of why people use dating apps and seek approval from their peers, which is not interesting to the majority of people.

I went to a rave in SF in 90s. Outside a dude stabbed another dude, then told my group of friends to circle around him and walk him down the street. SF has been... intense... my whole life.

Janis Joplin was a hooker in SF.

What world are you talking about? You talking about the very small window of GAP commercial San Fran? Shoe store Haight Asberry versus 'doses, doses' Haight?

I've had tinnitus since I was a child. It's probably due to a procedure they used to do around here an children with ear infections. Nowadays, I rarely notice it. But I remember in my teens, it sometimes was absolutely excruciating because I had no way of coping or tuning it out. This is very interesting. I might consider trying it. If there's something I'd really want to experience at least once, it's that "absolute silence" so many mention when being out in the forest it country side.

> Do you think a fat pig is beautiful? Like a hairy fat pig that snorts and rolls in the mud… is this animal so beautiful to you that you would want to make love to this animal?

I don't want to make love to the night sky, so that last bit is completely irrelevant to the question of beauty. As for whether a pig is beautiful, sure, in its own way. I think they're nice animals and there is something beautiful in seeing them enjoy their little lives.

> Of course not! Because pigs are intrinsically and universally ugly...

It would seem not.

Hi HN!

I've always wondered how 2D elements are rendered on a computer screen, so as a first step, I wrote a tiny TrueType renderer to help me understand it. I did a bunch of trial and error, and during that process, a good amount of notes are accumulated. Then eventually I thought it might be interesting for others too.

I hope you enjoy the article, Have fun :)

> is your argument now that an LLM can capture arbitrary state of the wider world as a general rule, eg pretending to be a Swift compiler (or LSP), without overfitting to that one task, making all other usages impossible?

Overfitting happens, even in humans. Have you ever met a scientist?

My points have been only that 1: language encodes a symbolic model of the world, and 2: training on enough of it results in a representation of that model within the LLM.

Exhaustiveness and accuracy of that internal world model exist on a spectrum with many variables like model size, training corpus and regimen, etc. As is also the case with humans.

Yes indeed. When I was a young man I heard the now famous quote "There's no place for the state in the bedrooms of the nation" by Pierre Trudeau. It was concerning the homosexuality debates in the politics of the 60s, but it always stuck with me as a generally good rule of thumb, do we really need to bring this stuff into politics? Who I pray to, who I sleep with, and what my T levels are, don't seem particularly germane. You put it eloquently, the political universe really does spend considerably too much energy demonizing what is really innate human behavior.

Most days, you’ll find me in sam, regexing my way to bliss like some monastic scribe with a terminal fetish. When I feel the urge to let AI stroke my curiosity or scaffold a long template like magic, I cut, paste, and drop it into a local or remote model like a well-trained familiar.

But I’ve also written larger applications and, frankly, a ridiculous amount of documentation in Acme. That 9P protocol was my backstage pass: every window, every label, was accessible and programmable. I could, for example, hook into a save event and automatically format, lint, and compile ten or fifteen years before most IDEs figured out how to fake that kind of integration.

Sure, the system demands precision. It doesn't coddle. But for me, that was the feature, not the bug. The rigor sharpened my thinking. It taught me to be exact or be silent, forcing me to pause when I usually would not.

I too had exactly the same constsnt ringing in my left ear.

I could not get to sleep because the noise was so loud and intense.

It reminded me of those spy films where they torture someone playing loud heavy metalcore all day and night.

I had a X-ray, ultra-sound and two Consultants had a look.

Both said that there was nothing wrong with my ear. No ear wax, no damage, no issues at all.

They both mentioned that tense facial and neck muscles may be a cause.

As well as the constant ringing, there is a sound like a central eating system, thumping and groaning away, in both my ears too. I initially thought the thumping and groaning was the Mrs snoring.

I bought some earloops thinking my ears were too sensitive and I was somehow hearing noises from the houses down the road and the motorway traffic 3 miles away. to no avail, even with the earloops blocking all exterior noise, I still had the high pitched and low piched internal noises.

I found a way to reduce the noise.

I was laying in bed one night and I was relaxing my jaw when I noticed that if I opened my mouth and let my jaw hang loose all the noises stopped.

So over a month or so I tried to train my jaw to be less tense and more relaxed.

For me it worked.

it was my jaw.

One of the insidious things about anxiety and panic disorders is the feedback loop of focusing on the distressing symptoms, which causes more distress, which creates more symptoms, etc. For many the "way out" for anxiety is to create space and simply allow the unwanted sensations and feelings to exist.

Tinnitus and anxiety are comorbid. It's healthy to just practice letting it be if you can.

Yes, I know. And I know iXsystems folks too. If you want stable, battle-tested ZFS, Solaris is the only supportable option on Sun hardware like the good ol' (legacy) Thumper. OpenZFS isn't tested well enough and there's too much hype and religious zealotry around it. For person use, it's probably fine for some people but, at this point, semi alternatives such as xfs and btrfs [thanks to Meta] have billions more hours of production usage.

Of all Schmidhuber's credit-attribution grievances, this is the one I am most sympathetic to. I think if he spent less time remarking on how other people didn't actually invent things (e.g. Hinton and backprop, LeCun and CNNs, etc.) or making tenuous arguments about how modern techniques are really just instances of some idea he briefly explored decades ago (GANs, attention), and instead just focused on how this single line of research (namely, gradient flow and training dynamics in deep neural networks) laid the foundation for modern deep learning, he'd have a much better reputation and probably a Turing award. That said, I do respect the extent to which he continues his credit-attribution crusade even to his own reputational detriment.

> Bro. Evolution is random walk. That means most of the changes are random and arbitrary based on whatever allows the squirrel to survive.

For the vast majority of evolutionary history, very similar forces have shaped us and squirrels. The mutations are random, but the selections are not.

If squirrels are a stretch for you, take the closest human relative: chimpanzees. There is a very reasonable hypothesis that their brains work very similarly to ours, far more similarly than ours to an LLM.

> So an LLM cant continuously learn? You realize that LLMs are deployed agentically all the time now so they both continuously learn and follow goals?

That is not continuous learning. The network does not retrain through that process. It's all in the agent's context. The agent has no intrinsic goals nor ability to develop them. It merely samples based on it's prior training and it's current content. It doesn't retrain through this process. Biological intelligence does retrain constantly.

> The energy efficiency is a byproduct of hardware. The theory of LLMs and machine learning is independent from the flawed silicon technology that is causing the energy efficiencies.

There is no evidence to support that a transformer model's inefficiency is hardware based.

There is direct evidence to support that the inefficiency is influenced by the fact that LLM inference and training are both auto-regressive. Auto-regression maps to compute cycles maps to energy consumption. That's a problem with the algorithm, not the hardware.

> The fact that training transformers on massive amounts of data produced this level of intelligence was a total surprise for all the experts

The level of intelligence produced is only impressive compared to the prior state of the art, and at its impressive modeling the narrow band of intelligence represented by encoded language (not all language) produced by humans. In most every other aspect of intelligence - notably continuous learning driven by intrinsic goals - LLMs fail.

Odd, I can `C-s` just fine in transient buffers. It works exactly like in other buffers.

The `C-h` override is pretty cool there too, e.g. if from magit-status I do `C-h -D` (because I'm wondering what "-D Simplify by decoration" means), then it drops me straight into Man git-log with point at

--simplify-by-decoration Commits that are referred by some branch or tag are selected.

(Ooh, I learnt a new trick from writing a comment, who say social media is a waste of time)

Can you provide a concrete example where that's faster? ripgrep should generally already be approximating `git ls-files` by respecting gitignore.

Also, `-uu` tells ripgrep to not respect gitignore and to search hidden files. But ripgrep will still skip binary files. You need `-uuu` to also ignore binary files.

I tried playing with your `rgg` function. First problem occurred when I tried it on a checkout the Linux kernel:

$ rgg APM_RESUME bash: /home/andrew/rust/ripgrep/target/release/rg: Argument list too long

OK, so let's just use `xargs`:

$ git ls-files -z | time xargs -0 rg APM_RESUME arch/x86/kernel/apm_32.c 473: { APM_RESUME_DISABLED, "Resume timer disabled" }, include/uapi/linux/apm_bios.h 89:#define APM_RESUME_DISABLED 0x0d real 0.638 user 0.741 sys 1.441 maxmem 29 MB faults 0

And compared to just `rg APM_RESUME`:

$ time rg APM_RESUME arch/x86/kernel/apm_32.c 473: { APM_RESUME_DISABLED, "Resume timer disabled" }, include/uapi/linux/apm_bios.h 89:#define APM_RESUME_DISABLED 0x0d real 0.097 user 0.399 sys 0.588 maxmem 29 MB faults 0

So do you have an example where `git ls-files -z | xargs -0 rg ...` is faster than just `rg ...`?

Yep, stroking is just filling of the space between offset curves (aka. parallel curves), and that "slightly scaled down version of the first" is the "calculate an offset curve explicitly" approach I mentioned.

Though it is very unpractical because the offset curve of a cubic bezier curve is not a cubic bezier curve anymore, instead it is an analytic curve of degree 10. Thus, in practice the offset curves for stroking are either approximated by polygons or implicitly sampled from signed distance fields.

Raph Levien has a good blog post about it:

https://raphlinus.github.io/curves/2022/09/09/parallel-bezie...

One more thing: Offset curves are different form classical scaling from a center point in all but the most trivial cases where there exists such a center; namely regular polygons. And cubic bezier curves can be concave, even have a self intersecting loop or form a cusp.

> Find that the culprit is not you, find that you’ve asked for help, find that they (AWS) failed to remediate, properly fix responsibility on the culprit and secondary responsibility on themselves, punch themselves in the crotch for a minute, and then solve the problem by canceling the account of the offending party.

Yeah, lawyers are notorious for blaming themselves and taking responsibility. You definitely won't just get blamed.

No, humans are not a series of band-aid patches where we learn facts in isolation. A human can reason, and when exposed to novel situations figure out a path forward. You don't need to tell a human how many rs are in "strawberry"; as long as they know what the letter r is they can count it in any word you choose to give them. As proven time and time again, LLMs can't do this. The embarrassing failure of Claude to figure out how to play Pokemon a year or so ago is a good example. You could hand a five year old human a Gameboy with Pokemon in it, and he could figure out how to move around and do the basics. He wouldn't be very good, but he would figure it out as he goes. Claude couldn't figure out to stop going in and out of a building. LLMs, usefulness aside, have repeatedly shown themselves to have zero intelligence.

I use it extensively to keep track of the status of my work. I draw comics, and each page is a separate file; while I'm generally working on one of the highest-numbered pages in the folder, it's real nice to instantly know by their visible tag colors that, say, pages 1-78, 80, and 82 are complete, while 79, 81, and 83-85 are in progress.

You can see an example of that here: https://egypt.urnash.com/blog/2019/01/06/how-i-work-file-org... - it's got a screenshot of the folder of pages for a comic I was doing that had two parallel narratives, so scrolling down to the bottom of the alphabetized list wouldn't even necessarily show all the in-progress files. (Yes, I could sort by other criteria, but stuff like 'last modified date' can bring in a lot of false positives.)

I have a saved search for files marked as "in progress". And another one for files marked as both "commissions" and "in progress". All of these files might be scattered throughout my file system in various places - comics have their own folder, personal work goes in a folder named with the year, commissions sometimes end up in the yearly folder, sometimes in their own subfolder - and these saved searches let me completely disregard that and quickly ask myself "what do I feel like spending time on today".

I also have a lot of files tagged as "experiments", all saved in the yearly folder. A lot of these are the result of me sitting there on the Illustrator subreddit and answering "how do I make Illustrator do something that looks like this" questions, and packaging them up in an easy-to-reuse way; I can just look in the Experiments tag when I want to find one of them and not bother keeping a special place for them.

I don't think there's any kind of mental map going on here, the whole usefulness of tags is that I can skip navigating my folder hierarchy. Different tags very clearly mark some files as different. You can make new tags and assign them names, but you're annoyingly restricted to seven colors, so there's really not much mental mapping to do.

I started hearing tinnitus a decade ago in a quiet room at night when I came back home after two years traveling the world at around 30 yo. Over the following months it became louder and noticed it more, then after maybe a year I could hear it all the time. During the day I could live with it but in the middle of the night I could not get back to sleep after waking up. It was causing a lot of anxiety because I was afraid of how much louder it may become.

I was thinking that maybe I cough something during my travels so I went to see a few specialists but they found nothing.

What I understand now is that the cause is probably all the vipassana meditation I did and some psychedelics I experimented with during my travel which opened some filters I had in my mind blocking sensor noise. It's the most plausible explanation for me.

The noise was probably always there, or maybe it got louder when I become older, but I never noticed it until it became disturbing.

A decade later the noise is still there, all the time, but it's not an issue at all anymore. It's not louder than before, and I have no negative feelings associated with it. I made peace with it and I can now easily ignore it, or to be more accurate, I can live with it and it'll disappear on its own after a short time until I put my attention back to it (voluntary or not).

As I'm writing this in a quiet room it's very loud, but that's fine, it just sensor noise. Soon enough I'll stop hearing it if I don't focus on it.

I hope reading this can help. I wish I had someone back then telling me that it would turn out okay to just accept it after doing some medical checks.

Another message of hope for anyone struggling with the possibility of having tinnitus:

I may not be able to fully recount all the factors but I believe my ears may have had some residual fluid after recovering from covid (my covid symptoms were entirely unpleasant and impacted me differently in many ways). Before my ears cleared up, I took a domestic flight where I actually got vertigo for a few 10s of seconds on ascent. My ENT believes my eardrum expanded to touch the inner ear.

The following day I went to a gun range and did skeet shooting for a couple of hours then shot really big guns and sniper rifles. The earplugs I brought myself were likely not adequate and taking them out and putting them in repeatedly in relatively cool weather likely didn't provide the best seal either.

That night or the next day I noticed lots of ringing in my ears and I started to become worried when it was still there even after a week. The worst was being in silent meeting rooms at work where it was most noticeable. It was extremely depressing and I nearly lost all hope.

I visited 2 separate ENTs and each just sent me re-take my yearly hearing test. They didn't really provide any comforting words other than to take the test and wear hearing protection, etc..

Before the hearing test (~2 weeks after the gun range and flights) I explained everything to the audiologist and he said "Lots of people have various degrees of tinnitus/ringing, just don't think about it. I have it and that's what I do. Don't let it bother you and live your life."

Interestingly enough, my audio test came back better than the previous 10 year results and since then I just don't think about it. If I do I can certainly hear it. My only personal takeaway is that the brain and body are very complex and have an arsenal of mechanisms to deal with trauma and that for this particular instance I've been very lucky.

I feel you. Here’s things you can try (in this order):

- Cut stimulant use (coffee, energy drinks) and alcohol

- Drink plenty of water

- Check blood pressure

- Talk to a dentist and check if you grind teeth or suffer from jaw stiffness

- Supplement Magnesium (chelated/glycinate, 300mg/day)

I’m ignoring issues of the ear canal (wax, secretions) since you mentioned it.

Studies point to tinnitus being either caused by changes in blood supply on the inner ear, of neurological origin or trauma. These are all measures I took and greatly improved my case (and when I neglect one of those, it comes back).
by burntsushi | 2025-10-18 18:22:37+00:00
I did it too, even after I initially released ripgrep. At this point, I've mostly re-trained my muscle memory to use `rg` in pipelines. (Particularly because I was careful to make sure `rg` worked just like `grep` does in pipelines.)

I also find that combining `-o/--only-matching` and `-r/--replace` has replaced many of my uses of `sed` and `awk`.
Show HN: Open-Source Finance Agent
by lucasastorian | 2025-10-18 18:22:39+00:00
Hey guys,

I’m open sourcing an autonomous financial research and analysis agent. The agent can search SEC filings, extract key financials, and build financial models.

It’s scored 80% on the public Finance Agent validation set with GPT-5, compared to the top result of 55% listed on their website for their private validation set.

But, their public validation set has mistakes. There are quite a few cases where the “ground truth” answers in the benchmark are wrong. I’ve documented each case with citations directly to SEC Edgar here (https://github.com/lucasastorian/intellifin-agent/blob/main/...)

Accuracy with GPT-5 jumps to 92% once we fix those mistakes in the eval.

You can clone the repo and rerun the benchmark yourself.

Next step should be turning this into an open-source “Cursor for Finance,” with a proper UI for equities research and financial modeling.

Feedback & questions are welcome.

In some power constrained scenarios that sort of thing is often petty reproducible.

Especially if the different SKUs have different power budgets. Laptop GPU naming and performance is a bit of a mess, as in the example shown (the 4060 on the Asus TUF Gaming A16 has a limit of 140w GPU+CPU, while the 4070 on the Asus Proart PX13 has 115w GPU+CPU - and even that is a "custom" non-default mode with 95w being the actual out-of-the-box limit).

With wildly varying power profiles laptop graphics need to be compared by chassis (and the cooling/power supply that implies) as much as by GPU SKU.
