Disclamer: probably dumb questions

so, the 20b model.

Can someone explain to me what I would need to do in terms of resources (GPU, I assume) if I want to run 20 concurrent processes, assuming I need 1k tokens/second throughput (on each, so 20 x 1k)

Also, is this model better/comparable for information extraction compared to gpt-4.1-nano, and would it be cheaper to host myself 20b?

People always joked that Incognito Mode is for porn, but I use it for search.

I don't want to be in a group of people, someone asks me to look up how old some celebrity is, and then information about that person gets pushed to me by algorithms from then on. It's a trite example, but a real one. I've found myself becoming aware of which topics the algorithms know I've looked into, and trying to groom that list.

In Europe, you can't presently use Gemini without being logged in - presumably having something to do with their recent tech laws. I don't know if there's a way to delete searches from Gemini either. I really don't like that.

I should be allowed to be curious about something without having that curiosity etched into my permanent record.

I played around with Diamond WM on my 3090 machine. I also ran fast SDXL-turbo and LCM models with ControlNets paired with a 3D game prototype I threw together. The results were very compelling, and I was just one person hacking things together.

This is 100% going to happen on-device. It's just a matter of time.

I worked there for 3 years and yes GitHub development happens on github.com. Of course there’s ways to deploy and rollback changes while the site is down but that’s very unusual. The typical flow happens in github.com and uses the regular primitives everybody uses: prs, ci checks, etc.

The pipeline for deploying the monolith doesn’t happen in GitHub Actions though but in a service based in jenkins.

Fun fact: playbooks for incidents used to be hosted in GitHub too but we moved them after an incident that made impossible to access them while it lasted.

It could be, but there’s so much hype surrounding the GPT-5 release that I’m not sure whether their internal models will live up to it.

For GPT-5 to dwarf these just-released models in importance, it would have to be a huge step forward, and I’m still doubting about OpenAI’s capabilities and infrastructure to handle demand at the moment.

> lisp 1 and 2.0

Do you mean Lisp-1 and Lisp-2 as in the number of namespaces?

https://dreamsongs.com/Separation.html - Goes into depth on the topic including pros and cons of each in the context of Common Lisp standardization at the time (ultimately arguing in favor of Lisp-2 for Common Lisp on grounds of practicality, but not arguing strictly for either in the future).

Common Lisp was a, more or less, unification of the various Lisps, not Scheme, that had developed along some path starting from Lisp 1.5 (some more direct than others). They were all Lisp-2s because they all kept the same Lisp 1.5 separation between functions and values. Scheme is a Lisp-1, meaning it unifies the namespaces. The two main differences you'll find are that in CL (and related Lisps) you'll need to use `funcall` where in Scheme you can directly use a function in the head position of an s-expr:

(let ((f ...)) ;; something evaluating to a function (f ...)) ;; Scheme (funcall f ...)) ;; Lisp

I'm not sure that math makes sense over the long run. Sure, at first you scaffold together an app from scratch, but I suspect over time, the LLM's capability of maintaining it precipitously drops. At some point, you will like reach a productivity level of zero, as now your application has become too complex to fit in a context window and you have no idea how it actually works. So what is the productivity multiplier then?

Yes, remember how copying anything from the code view would also copy the line numbers? It was a relatively small CSS fix, but took years!

I never quite understood why this didn't get fixed before by the way, because it really wasn't that hard. Usually when $big_corp takes over $small_outfit things get worse instead of better, due to overbearing $big_corp policy, culture clashes, leadership not really understanding what they bought, and things like that.

Whatever else can be said about Microsoft: in the year or two after they took over GitHub lots of things – small and large – got fixed or improved.

Satellite internet has its place but it's never going to be dominant. Any area with high density is better served by wires, and any area with medium density is better served by a combination of wires and cellular internet. Satellite only make economic sense for the truly remote; the astronomical and recurring infrastructure costs are just killer (Starlink satellites last for 5 years, buried fiber lasts for 50 at least (while providing better latency and throughput)).

Those are not comparable scenarios. You are omitting a lot of detail, which most people do, but the detail is important.

You need to give the bank $200k to get the $800k mortgage. Now you have $200k equity in the house, but you could have had that $200k equity in the stock market (compounding over the years).

Most of the replies here are for the US context. They use 6% interest rates over 30 year term. So their monthly repayments would be $4,797. And they're saying that renting the equivalent house would be about $2,500. I have no idea if this is realistic or not, but I'm just showing you what you're omitting from your calculations. We must also keep in mind, rent will increase over time, while your mortgage won't.

So now in the renting scenario, you have an initial $200k in the stock market growing at the nominal compound rate of say 8% each year. Then you're also investing the different between mortgage and rent (4,797 - 2,500 = 2,297) into the market each month, and that is also going to compound. Then you add in all the extra costs of home ownership over 30 years, then you calculate the value of your house that you now own outright at 30 years and compare it to the pot of money you put into the stock market while renting over those 30 years.

If your pot of money at the end of renting is enough to buy the house outright at that point, with some left over, then renting wins. Otherwise buying wins. (speaking purely financially)

I haven't done the calculations, but now you can see why your simple scenario is not sufficient.

I was baffled by the technical blog post they published on this subject, in 2023: https://github.blog/engineering/architecture-optimization/cr...

They completely redesigned the code navigation to load it dynamically using React. One of the regressions introduced caused the entries to be duplicated when searching for a word using Ctrl+F. Their solution to address this issue? Decompose the source character by character, assigning each individual character its own distinct HTML node...

Needless to say, in addition to abysmal performance (it took seconds to display on my laptop), this also caused new problems (such as the inability to search for certain composite emojis). The worst part is that they seemed proud of their hack, since they wrote a blog post about it.

I can point you to two legitimate climate scientists who in some sense deny climate change. They work on the satellite temperature record, which very clearly shows the increasing temperature:

https://en.wikipedia.org/wiki/John_Christy https://en.wikipedia.org/wiki/Roy_Spencer_(meteorologist)

Spencer's view is that there is a natural climate change going on that just happens to coincide exactly with increasing greenhouse gases. Christy believes that climate change is real and partly anthropogenic but that it's just not going to be all that bad.

If your friends think that it's not happening, you can point them at the data that these two gather:

https://www.nsstc.uah.edu/climate/

They'd disagree with your friends that humans are not involved at all. But your friends could switch to the position that climate change just doesn't matter and it'll all be fine.

7mths? What unit is that. Did they mean 7μs resolution? How is that special? I see youtubers doing nanoseconds.

edit: here is the important information in this article.

> Scorpius is a new accelerator project planned for the Nevada National Security Site (NNSS) that will use an electron beam that can be broken into customized pulses to deliver x-rays and capture multiple images only hundreds of nanoseconds apart.

So 0.1μs or 100ns temporal resolution 3D X-ray.

People do this, but it feels a bit weird to start a whole new language interpreter which is much more powerful than the pitiful shell language we use, just to split a field. Why not write your whole program in awk, then? It's likely more efficient anyway.

The canonical shell tool to split fields is cut. Easy to use, simple to read.

For the very common use case to set variables to fields, use the shell built-in read. It uses the same IFS as the rest of the shell.

With something like Devin, where it integrates directly with your repo and generates documentation based on your project(s), it's much more productive to use as an agent. I can delegate like 4-5 small tasks that would normally take me a full day or two (or three) of context switching and mental preparation, and knock them out in less than a day because it did 50-80% of the work, leaving only a few fixes or small pivot for me to wrap them up.

This alone is where I get a lot of my value. Otherwise, I'm using Cursor to actively solve smaller problems in whatever files I'm currently focused on. Being able to refactor things with only a couple sentences is remarkably fast.

The more you know about your language's features (and their precise names), and about higher-level programming patterns, the better time you'll have with LLMs, because it matches up with real documentation and examples with more precision.

It's not like blockchain. Blockchain legitimately made things slower and less useful for dubious benefits.

AI is more like the early web. There is definite value that people can see, but no one really knows how to monetize beyond the incredibly obvious 'sell people access to it', so everyone is throwing spaghetti at the wall waiting for it to stick. When someone gets it to stick, there will be a giant amount of money coming at them, but until then there will be a ton of people with sauce all over their faces looking like idiots.

That's not even a devil's advocate, many other animals clearly have consciousness, at least if we're not solipsistic. There have been many very dangerous precedents in medicine where people have been declared "brain dead" only to awake and remember.

Since consciousness is closely linked to being a moral patient, it is all the more important to err on the side of caution when denying qualia to other beings.

>Oh, and don't scroll LinkedIn. Or Twitter. Ever.

This is all you have to takeaway from this article. Social media is a cesspool of engagement farmers dropping BS takes to get you to engage out of FOMO or anger. Every time I'm on there, I am instantly reminded why I quit going there. It's not genuine and it's designed to capture your attention away from more important things.

I've been using LLMs on my own for the past few years and we just recently started our own first party model that we can now use for work. I'm starting to get into agentic actions where I can integrate with confluence, github, jira, etc. It's a learning curve for sure but I can see where it will lead to some productivity gains but the road blocks are still real, especially when working with other teams. Whether you're waiting for feedback or a ticket to be worked on, the LLM might speed run you to a solution but you better be ready with the next thing and the next thing while you're waiting.

I know that ads are based on impressions as I told you before, but my money still has to end up somewhere even if I am using an ad blocker. So where does it end up if not as ad revenue on some websites? You must not confuse the people paying for the ads and in turn for the ad revenue of websites by buying stuff with the people deciding how that money gets distributed among all the websites by looking at ads.

We can even go one step further, if anyone is screwing over websites, then that is the ad industry by not paying for blocked ads. I buy an iPhone and Apple takes some additional money from me to spend on advertising. I did not ask for that but I am fine with it. Now I expect Apple to spend the money they took from me on ads in order to support websites. But if the guy that Apple wants to show the ad that I paid for does not want to see it and blocks it, then I want Apple to respect that and still pay the website. I know, not going to happen, but do not put the blame on people blocking ads.

"dangerously" and "fast" are not synonyms (while drunkess obviously is dangerous regardless). The 280 in San Mateo County is designed for 80MPH, with banked turns, gentle curves, etc. The speed limit is of course 65. If most people are driving 80-85, and you enter that highway and drive 60, which is a perfectly reasonable speed according to the speed limit, you are much more likely to cause an accident than if you just drive the speed of the people around you.

It's fine to point out that many people are terrible drivers and that a given crash that happens is more dangerous at a higher speed and if everybody were to drive under 60 at all times we'd all be safer, but clearly that will never happen unless we install a totalitarian government, put governors on all cars and give prison time for disabling them, with enforcers stationed everywhere to monitor. But no democracy would vote for that, so I don't think it's worth spending much mental energy on such hypotheticals.

> encourage

I think just the opposite: My feature would encourage people like me, who drive a "fast car" and can occasionally accidentally go too fast if a road is especially uncongested, to slow down to the speed that is customary or that others are driving, by reminding me that I could get a ticket and that driving faster than everyone else is dangerous.

I think AI is going to make senior engineers at big tech companies 10x more productive.

A lot of senior engineers in the big tech companies spend most of their time in meetings. They're still brilliant. For instance, they read papers and map out the core ideas, but they haven't been in the weeds for a long time. They don't necessarily know all the day-to-day stuff anymore.

Things like: which config service is standard now? What's the right Terraform template to use? How do I write that gnarly PromQL query? How do I spin up a new service that talks to 20 different systems? Or in general, how do I map my idea to deployable and testable code in the company's environment?

They used to have to grab a junior engineer to handle all that boilerplate and operational work. Now, they can just use an AI to bridge that gap and build it themselves.

Same. I'm on the $200 plan and I find Opus "better", but Sonnet is more straight forward. Sonnet is, to me, a "don't let it think" model. It does great if you give it concrete and small goals. Anything vague or broad and it starts thinking and it's a problem.

Opus gives you a bit more rope to hang yourself with imo. Yes, it "thinks" slightly better, but still not good enough to me. But it can be good enough to convince you that it can do the job.. so i dunno, i almost dislike it in this regard. I find Sonnet just easier to predict in this regard.

Could i use Opus like i do Sonnet? Yes definitely, and generally i do. But then i don't really see much difference since i'm hand-holding so much.

I'm fine paying for search, but I don't want to use LLMs and therefore I don't want to _pay_ for access to LLMs that I'm not going to use. If Kagi offered a lower cost subscription with zero LLM bullshit then I would happily resubscribe. I'm not holding my breath though, being able to actually find information on the internet is just probably dead forever.

I'm disappointed that the smallest model size is 21B parameters, which strongly restricts how it can be run on personal hardware. Most competitors have released a 3B/7B model for that purpose.

For self-hosting, it's smart that they targeted a 16GB VRAM config for it since that's the size of the most cost-effective server GPUs, but I suspect "native MXFP4 quantization" has quality caveats.

> Vim's hjkl make sense as you start using the tool. tmux's Ctrl-B for a prefix doesn't make sense, so that leads to remapping.

Hmm, I'm still confused:

* How do Vim's hjkl start to make sense? They've always seemed arbitrary. 'l' should stand for 'left', but it takes me right!

* How is a different keyboard shortcut less confusing than ctrl-b. They all seem arbitrary. You remapped it to ctrl-a. Maybe you were used to GNU Screen?

Hi HN,

ClipCert is a personal project I built to explore a simple idea: Can we use cryptographic signing (not AI) to prove whether a video is authentic?

With the rise of deepfakes and AI-generated content, I wanted to explore a way for creators, journalists, publishers, public figures or anyone really to digitally sign video content so that anyone else can later verify its integrity.

How it works: -You upload a video, and it's signed with your private key. -Later, anyone can verify that video using your username (linked to your public key). -The system gives a match percentage, showing how closely the submitted video matches what was originally signed.

It’s not detection, it’s verification. ClipCert doesn’t try to detect fakes, that’s not the goal. Instead, it’s about proving that what someone says is real can be verified as real. The long-term idea is: if a video comes from a known journalist or publisher, and it’s cryptographically signed with their private key, anyone should be able to verify its authenticity, independently, and with confidence. ClipCert uses traditional cryptography to enable that.

Right now this is just a proof-of-concept (scaled down i.e. 10s max videos, .mp4 only, etc.). I’d love your feedback — on the concept, tech, risks, and use cases. Could this add real-world value?

POC here: https://www.clipcert.com/POC More background: https://www.clipcert.com/about

Feel free to signup, login and test!

Thanks — happy to answer anything. Stu

if you are working in a domain you know well, ai will not save you any time. if you are not, you will have to carefully review the ai while not building any intuition or background sources anyway so you end up not saving time and developing a new dependency.

but every company is going to enshittify everything they can to pidgeonhole ai use to justify the grifters costs

i look forward to years out when these companies trying to save money at any cost have to pay senior developers to rip all this garbage out

> There is no landlord renting at a loss.

Actually not true. Landlords are just as susceptible to speculation as everyone else and just as capable of not doing the math as everyone else. There are plenty of landlords who are taking a loss on the monthly rent compared to their mortgage bill because they can't find anyone to rent at a price where they would break even on the mortgage, and refuse to sell because they're speculating that housing prices will rise faster than their losses, and/or that the losses are simply part of the cost of building equity.

I am wondering if PHP explicitly rejecting Hack-style pipes (especially given the close ties between PHP and Hack, and that PHP doesn't have partial application, but JS does, sort of, though its UX could be improved) will add leverage to the F#-style proposal over the Hack-style.

It may be useful data that the TC-29 proposal champions can use to fight for the F# style.

> Web components are low-level APIs and just don't have the ergonomics of frameworks without a library to help. For a few elements built by a few true believers, this is ok, but when you scale it out to every component in a complex app with company-wide teams you need the ergonomics and consistency-setting of a declarative and reactive API.

GitHub did have their own declarative semi-reactice webcomponent framework. It's pretty nice!

https://github.github.io/catalyst/

It not at all coincidentally bears some resemblance to the (thinner, simpler) Invoker Commands API that has shipped in HTML (they share a main author):

I similarly am surprised at how fast they are progressing. I wrote this piece a few months ago about how I think steering world model output is the next realm of AAA gaming:

https://kylekukshtel.com/diffusion-aaa-gamedev-doom-minecraf...

But even when I wrote that I thought things were still a few years out. I facetiously said that Rockstar would be nerd-sniped on GTA6 by a world model, which sounded crazy a few months ago. But seeing the progress already made since GameNGen and knowing GTA6 is still a year away... maybe it will actually happen.

People were perfectly fine with 56k when most of the Internet was just text. Stalling the internet at that speed could have been argued for by saying anyone who wants DSL/Cable at home just wants it for Napster.

Fast Internet speeds allow for unthought of innovations. If we get up to terabyte speeds, maybe nobody cares about watching Netflix if we can now have holodecks that become fully immersible experiences that allow for educational training and, to your chagrin, entertainment as well. Maybe LLMs are basically free because everyone can just have all of human content constantly updated.

Letting speeds stall stifles innovation and let's Netflix just continually up their prices for the same 720p content you refer to.

This isn’t really surprising at all IMO, but it’s nice that it’s been confirmed.

> “The researchers believe semaglutide’s anti-aging properties stem from its effects on fat distribution and metabolic health. Excess fat around organs triggers the release of pro-aging molecules that alter DNA methylation in key aging-related genes. By reducing this harmful fat accumulation and preventing low-grade inflammation - both major drivers of epigenetic aging - semaglutide appears to create a more youthful biological environment.“

In other words, being medically obese ages your body quite a bit, its stresses out your body with inflammation, etc. Taking Ozempic helps people lose weight, which also reduces inflammation. This is sort of like saying we proved rain (usually) increases humidity lol. A very obvious finding.

The article even says “ Randy Seeley from the University of Michigan Medical SchoolView company profile expressed little surprise at the findings” :)
