Usually the narrative for externalizing these kinds of costs is that the investment will result in lots of jobs in the upgrade area.

Sometimes that materializes.

Here the narrative is almost the opposite: pay for our expensive infrastructure and we’ll take all your jobs.

It’s a bit mind boggling. One wonders how many friends our SV AI barons will have at the end of the day.

Most of the other ones at the time it was pop and the data was gone. You had to jump thru some hoops to make it work as persistent. Not 'hard' but just more annoying. Kafka has that out of the box. Where kafka starts to come apart is how to set it up. Its configuration is a bit tedious to setup.

Depends on the engine. They had an option for a turbo 1.5l l15 and a 2l k20. Plus a few others I don't know were offered in usdm. No idea about Thailand but if it wasn't a 2 liter, I think it was not a k series.

In a very niche form of motorsport, the civic sport is top in class for a lower tier Street class with the SI being top of another lower tier Street class.

I come to HN because there are absolutely wonderful discussions in the threads. Not always, not consistently, but often... the sort of conversations (even sometimes arguments) that leave me feeling energized, better informed, and/or fired up over some new project or technology I'd never heard of before.

That said, equally often I feel like a hermit who limps into town every couple weeks, wild-eyed and twitchy, and listens to other people's conversations, smiles and nods, maybe says something friendly and innocuous, and then I notice that there's a circle of people gambling on street-fighting urchins or chanting "ass-to-ass" at some degrading sideshow, and I have to haul my ass back out to the sticks before I'm found out and my blood is ceremonially drained to inaugurate some hellish techbro kegger 'n' orgy.

I enjoy the [GoL -> our “reality” -> outside-the-simulation] comparison. It really drives home how unlikely we would be to understand the outside-the-simulation world.

Of course, there are other variants (see qntm's https://qntm.org/responsibility) where the simulation _is_ a simulation of the world outside. And we have GoL in GoL :-)

The point that people are making is that while restricting overt internet porn does remove it from sight of a lot of kids, it will also continue to circulate as "samizdat" through whatever filesharing mechanisms exist. When I was at school someone got busted for distributing BBS porn on floppy disks, no network required. Now we have terabyte SD cards.

Diminishing returns. Eventually real world word of mouth and established trusted personalities (individuals) will be the only ones anyone trusts. People trusted doctors, then 2020 happened, and now they don't. How many ads get ignored? Doesn't matter if the cost is marginal if the benefit is almost nothing. Just a world full of spam that most people ignore.

Any systems / low-level / embedded developpers who could give their grain of salt on this? I'm a student and I'm specializing in embedded and systems programming, but everyone around me (webdevs) tells me LLMs will take over and writing C and Zig and Rust is useless... Should I just give up on my passion and embrace AI and high-level programming?

You can still get brand new generic motherboards for old CPUs.

I swapped out old ASUS MBs for an i3-540 and an Athlon II X4 with brand new motherboards.

They are quite cheaper than getting a new kit, so I guess that's the market they cater to: people who don't need an upgrade but their MBs gave in.

You can get these for US$20-US$30.

> The people who built Skara Brae had more advanced architecture than the Romans did

But why did they put so many spinner traps and magic mouths in the perfectly rectilinear, monster-filled maze underneath the town?

In all seriousness, I had no idea until just now that Skara Brae was a real place, and not just a setting for tales sung by bards.

Yann LeCun tis saying that some Paul Halpern from X alleges that Albert Einstein (the one from the stories!) had a conversation with some psychologist more than a hundred years ago where those words were uttered.

If true, this is somehow meant to be taken as a rule/law that language and thoughts are fundamentally different things.

No wonder why he got sacked, lol.

In this workload, it happened to be, in a lot of workloads it is not at all. This is quite likely because over time media sizes have increased greatly. Microsoft research on operating systems shows that contiguous chunks at 64MB don't really show any IOPS penalty in practical usage scenarios.

I work on workloads that work with thousands to millions of small files. 1k to 1MB. I can promise you that the IO effect is massive, with shortcuts like working directly on archive files/zips where they are read and written at once saves massively on hardware costs as IOPS tend to be expensive. This is with fast NVMe disks, no spinning platters involved. Also small files massively increase write amplification on SSDs.

There probably is significant savings in deduping 'tiny' files, but the moment you get past a particular threshold it drops off, and the vast majority of game assets have increased over that size.
Show HN: LLM-Infra-Lab – A minimal, reproducible lab for LLM systems
by Sai-HN | 2025-12-04 15:11:15+00:00
I built this because most LLM infra repos are either huge (impossible to learn from) or too toy-like to reflect how real inference systems behave. There was no middle ground for people who want to understand KV caching, batching, routing, sharding, or scaling—without needing a cluster or reading 5k-line abstractions.

LLM-Infra-Lab provides small, readable, reproducible demos of real infra primitives (vLLM-style KV cache mock, batching simulator, minimal router/workers, JAX pmap model, etc.), all runnable on CPU/Colab. It’s meant as a learning & experimentation lab for anyone who wants to see how LLM systems actually work under the hood.

Happy to answer questions or add modules people request.

Quadtrees are also quite useful for generating fractals. A very related project of mine, Lambda Screen [0], explores this by encoding these functional quadtrees directly in lambda calculus and rendering the structure based on Church booleans being true (white) or false (black).

With fixed point recursion, this allows for very tiny definitions of IFS fractals. For example, fractals like the Sierpinski triangle/carpet only require ~50 bit of binary lambda calculus [1] [2]!

One of the interesting quirks of the Honda K-series is that it spins “backwards”. If you try to mate one to a different transmission (or try to mate a different engine to a K-series transmission), it’s going to give you, uh, interesting results! Lots of people found out the hard way when they used their Fast & Furious inspiration to do JDM swaps :)

What's become clear is we need to bring Section 230 into the modern era. We allow companies to not be treated as publishers for user-generated content as long as they meet certain obligations.

We've unfortunately allowed tech companies to get away with selling us this idea that The Algoirthm is an impartial black box. Everything an algorithm does is the result of a human intervening to change its behavior. As such, I believe we need to treat any kind of recommendation algorithm as if the company is a publisher (in the S230 sense).

Think of it this way: if you get 1000 people to submit stories they wrote and you choose which of them to publish and distribute, how is that any different from you publishing your own opinions?

We've seen signs of different actors influencing opinion through these sites. Russian bot farms are probably overplayed in their perceived influence but they're definitely a thing. But so are individual actors who see an opportunity to make money by posting about politics in another country, as was exposed when Twitter rolled out showing location, a feature I support.

We've also seen this where Twitter accounts have been exposed as being ChatGPT when people have told them to "ignore all previous instructions" and to give a recipe.

But we've also seen this with the Tiktok ban that wasn't a ban. The real problem there was that Tiktok wasn't suppressing content in line with US foreign policy unlike every other platform.

This isn't new. It's been written about extensively, most notably in Manufacturing Consent [1]. Controlling mass media through access journalism (etc) has just been supplemented by AI bots, incentivized bad actors and algorithms that reflect government policy and interests.

Yep, this is just a ploy to create a PMC that actually has no skill workers in it. You just shove MBAs, nepos, etc into these roles and just have them gobble up some managerial course which is often nothing but: delegate, CYA, and 'manage expectations.'

I dont think we need to go back to the old ideas of The Manager who is Above It All and Doesn't Get Their Hands Dirty. At least at middle levels.
by compoundedges | 2025-12-04 15:12:41+00:00
We have been using it for the last 8 months in production at CompoundingEdges. It's been great for allowing users to generate large amounts (100-300k records/day) of their own isolated data and automatically persist it to their local machine. The only hiccup we have had had been throttling data to be saved via the webworker.

We are not syncing with Electric, but I've heard good things about it.
Show HN: FluentUI Icons – Search 6k+ Microsoft Icons with MCP Support for Claude
by OndrejValenta | 2025-12-04 15:12:44+00:00
I built a searchable database of Microsoft's FluentUI System Icons with an MCP server so you can search icons directly from Claude. I just can stand that these icon catalogs are hostile to us, developers.

It supports fuzzy search with synonyms, platform-specific generators for iOS/Android/React/Svelte + a custom generator for specific needs, and a JSON/text API for search.

Auto-syncs daily with Microsoft's repo.

Give it a try, I use it for my current development and so far it works pretty good.

"Servant Leadership" is a term was coined by Robert Greenleaf in his 1977 book "Servant Leadership: A Journey into the Nature of Legitimate Power and Greatness", which is very specifically about being a church leader. Many of the more generic ideas are applicable in any leadership scenario but if you read the book it's very clear that it was not designed with business leadership in mind. You shouldn't really expect it to apply to being a leader in a tech company.
Show HN: ToolDexo – 29 free online tools (calculator, converter, generator)
by WebCreator | 2025-12-04 15:13:06+00:00
Hi HN!

I built ToolDexo - a collection of 29 free online tools because I was tired of websites that force you to sign up just to use a calculator or word counter.

What's included: - Calculators: BMI, calorie, mortgage, loan, tax, grade, tip, percentage, age, compound interest - Converters: Currency (36 currencies with live rates), unit, timezone, file size - Generators: Password, QR code, favicon, color picker, Lorem Ipsum, random number - Text tools: Word counter, case converter, character counter, text compare, Markdown editor - Dev tools: JSON formatter, Base64 encoder/decoder

Tech stack: - Pure vanilla JavaScript (no frameworks) - All processing done client-side - Hosted on Vercel - 100/100 Lighthouse score - Works offline after first load

Design philosophy: - Zero signup required - No paywalls or premium tiers - No data collection or tracking - All tools work instantly - Mobile-friendly

I built this over the past few weeks as a side project. The favicon generator was just added based on my own need for one.

Would love feedback from the HN community on: - Which tools are most/least useful - What tools to add next - UI/UX improvements - Any bugs you find

Gambit Robotics | Senior Full-Stack Engineer | NYC | Onsite | Full-time

Hi!

I’m Nicole (Ex-Google AI), cofounder of Gambit Robotics with Eliot Horowitz (cofounder/CTO MongoDB). We’re hiring a Senior Full-Stack Engineer to work directly with us in our NYC office (in-person only).

Gambit is an AI-powered kitchen assistant that mounts magnetically under most range hoods or microwaves. It uses computer vision, thermal imaging, and on-device AI to understand what’s happening in the pan in real time, and handles the hardest parts of cooking — heat, timing, and doneness — so people get better results with less stress.

You:

- 7–10 years of experience

- Strong ownership and product sense

- Thrive in fast-paced, ambiguous environments

- Experience with IoT / hardware is a plus

We’re moving quickly from prototype to product and launching at CES with a Kickstarter in January. It’s a seed-stage startup with high autonomy, real impact, and a very intense (and fun) next few months.

If you or someone you know might be a fit, email me: nicole@gambitrobotics.com

You have to configure it with the lowest-spec SSD and then replace that with an aftermarket 4 TB SSD at around $215. The P14s I bought last week, with that and the 8 GB Nvidia GPU, came to a total of USD $2150 after taxes, including the SSD. Their sale price today is not quite as good as it was last week but it's still in that ballpark; with the 255H CPU and iGPU and a decent screen, and you can get the Intel P14s for $2086 USD. That actually becomes $1976 because you get $110 taken off at checkout. Then throw in the aftermarket SSD and it'll be around $2190. And if you log in as a business customer you'll get another couple percent off as well.

The AMD model P14s, with 96 GB and upgraded CPU and the nice screen and linux, still goes for under $1600 at checkout, which becomes $1815 when you add the aftermarket SSD upgrade.

It's still certainly a lot to spend on a laptop if you don't need it, but it's a far cry from $5k/year.

No they are making higher margins, but not getting as much profit as they could have.

Look at the standard Econ 101 supply-demand curve.

If they could make and sell twice as many chips, it would not cut there margins anywhere near half. They would be making much more.

When demand spikes up and down there will be pain. Because booms are not predictable, in timing, size or duration. And accelerating supply expansion is very expensive, slow, and risky.

Many boom prompted RAM supply expansions have ended in years of unprofitable over capacity.

> This is OAI doing suppliers dirty by making economy distorting moves without transparency, intentionally distorting the market in an effort to hurt competitors. Yet another example of the “free market” creating destruction for the general public.

At the speed OpenAI is growing, it's far more likely they're trying to protect themselves first, not harm competitors. The market only exists because it's free / semi free. Were it controlled by statist bureaucrats - which is the sole alternative back in reality - the situation would be drastically worse. Just ask Soviet Russia. You'd get your meager once every ten year DRAM ration and you'd like it.

The general public isn't the standard of morality or good. Invoking it is meaningless.

Well, it kind of depends. With XMP (which is overclocking) I've found plenty of kits on Ryzen not passing memtest with the XMP settings. Different CPUs seem to be able to run their memory controller harder without error.

And then there are other factors like more sticks of ram stressing things further. I had to downclock to get memtest stable when running 4 sticks even though each kit ran fine on it's own. But that is expected as well as 4 sticks stresses the memory controller even further.

I confess I don't have any real recent experience with DDR5 though, mostly with DDR4 on Ryzen 1000-5000 series.

something I havent seen mentioned: the people who are AI's biggest proponents are distinctly unlikeable humans. Look at Elon Musk with Grok, its disgusting. Look at Sam Altman, Alex Karp, look at Peter "Im not sure humanity should continue" Thiel. These people are wildly misanthropic, of course it gives the whole thing an unpleasant miasma.
Show HN: Invest in ETFs and Stocks from Inside ChatGPT and Claude
by rothblatt | 2025-12-04 15:15:49+00:00
Hi HN! I’m Elias, cofounder of Treasury. We built a remote MCP server that you can connect to AI Assistants. This lets you go right from doing investment research in the assistant to placing the orders. We call this product Dialog.

Dialog is commission free, we charge no investment management fee, and you can give it a try at https://dialog.treasury.app.

(Currently ChatGPT and Claude require you to have a paid account to connect external connectors.)

We’ve found this particularly interesting on the ChatGPT and Claude mobile apps; the simplicity of chat + the power of the AI models let’s you do things that would be quite slow otherwise (e.g., “Help me build a portfolio to invest in Treasury that is 70% long-term diversified index funds, 20% exposure to the prices of Water and Gold appreciating, and 10% in three high-potential AI Stocks. Once we’ve agreed on the investments, invest $1,000 a month.”)

Our vision for Dialog is to build a complete investing app with the AI Assistant as the interface and the ‘brain.’ If AI Assistants become the new dominant user interface, Dialog is an example of how investing could work.

> You don't need any AI for this.

AI accelerates it considerably and with it being pushed everywhere, weaves it into the fabric of most of what you interact with.

If instead of searches you now have AI queries, then everyone gets the same narrative, created by the LLM (or a few different narratives from the few models out there). And the vast majority of people won't know it.

If LLMs become the de-facto source of information by virtue of their ubiquity, then voila, you now have a few large corporations who control the source of information for the vast majority of the population. And unlike cable TV news which I have to go out of my way to sign up and pay for, LLMs are/will be everywhere and available for free (ad-based).

We already know models can be tuned to have biases (see Grok).

I'm using it for a service that has DB dependencies. Instead of using SQLite in tests and PG in production, or spinning up a Postgres container, you use Postgres via pglite.

In my case, the focus is on DX ie faster tests. I load shared database from `pglite-schema.tgz` (~1040ms) instead of running migrations from a fresh DB and then use transaction rollback isolation (~10ms per test).

This is a lot faster and more convenient than spinning up a container. Test runs are 5x faster.

I'm hoping to get this working on a python service soon as well (with py-pglite).

"Servant leadership" is not a buzzword but it's been misused and abused by Big Corporations to the point that it basically lost its meaning [1].

For me - personally - the idea is about being less of a boss and more of a nightwatchman or janitor.

I believe in agency and ownership and - in sane environment - people can be left alone with clear objectives. It's more about removing obstacles.

I'll give you a simple example.

Once a week a maid comes to our apartment. Despite a clear power balance disproportion (it's easier to find a new maid than a senior engineer) and her being used to being transparent and prioritizing to not disturb tenants for me it's the other way around. I'm super happy to hastily finish a call or leave my room is she feels the need to disturb me, and if she needs an extra pair of hands I'm happy to help her with anything. After all, I'm more interested with the final result than feeling important.

We have a bucket list of tasks than has to be performed that slightly exceeds her capacity and she has a full right to prioritize things. It took my a while but I eventually convinced her that it's ok to skip things - like cleaning the windows - if she's feeling under the weather or it's cold outside rather than faking it.

Most of the pointy hairs I worked in corporate environments would probably prepare a list of requirements and walked through the apartment with a checklist every time she would finish giving her a full, harsh performance review.

But that doesn't build trust and long term relationship.

And after some time she developed - what people around here call ownership - and sometimes I feel she cares about the household more than I do.

Hope that makes sense.

This is like economic growth: First bad, then upwards trajectory, then now in free-fall

You are describing it: Things in programing were bad, then suddenly all in the upside UNTIL it start to coming down.

Is not a refute of the problem. Is to pick a moment were both were bad, and like all the discussions about tech, MASSIVELY ignore that MASSIVE internet with MASSIVE money with MASSIVE backing is worse than before.

Is like people complaining that pistols on the wild west kill as do nuclear weapons, ignoring the massive difference in size and blast damage

Skeletons of data centers and some components (i.e. cooling) have long shelf life, but they're also ~10% of investment. Plurality of fiber and rail went towards building out linear infrastructure where improvements can be milked at nodes to improve network efficiency (better switches etc).

VS plurality of AI investment, i.e. trillions are going towards fast deprecating components where we can say with relative confidence will likely be net negative stranded assets in terms of amoritization costs if current semi manufacturing trends continues.

Keeping some mission critical legacy systems around is different than having trillions that makes no financial sense to keep on the books, i.e. post bubble new gen hardware will likely not have scarcity pricing or better compute efficiency (better apex and opex), there is no reason to believe companies will legacy GPUs around at scale if every rack loses them money relative to new hardware. And depending on actual commercialization compute demand, it can simply make more economic sense to retire them than keep them going.
