reducing complexity is important but is hardly the fundamental reason to choose between server side or client side rendering or state management. that just depends on the nature of the problem and the context it has to be solved in. sometimes it doesn't matter, then you have a choice.

you guys are furiously arguing (and not really listening) about this or that hammer being good enough to treat every problem as a nail, like ssr was the "holy hammer". well, it isn't and not every problem is a nail, and while datastar looks excellent to me i simply would have no use for it if i needed client side logic or state for whatever reason.

One positive of this whole AI is its really made me think critically about what is actually valuable to my life.

If all new media is just endless stuff produced by AI I’m kind of not interested. Which is interesting because it made me realize I don’t actually care about the media itself, but the connection to another human (through movies or writing or whatever).

It’s also made me take a step back and take a hard look at technology and I truly believe that at least 60% of software is just useless garbage that really doesn’t need to exist. I’ve been slowly cutting “smart” things, time trackers, just any random app out of my life and I honestly don’t miss it.

Not sure what direction I’m going with this but there has to be a better use of our best minds than more ads or more entertainment.

In terms of production, SSD flash chips that go into SATA and NVMe drives can be pretty much the same: only the external interface can be different.

The biggest cost driver for flash chips is not the speed they can be read from and written to in bursts, but how resilient they are (how many times can they be written over) and sustained speed (both based on the tech in use, TLC, SLC, MLC, 3D NAND, wear levelling logic...): even for SATA speeds, you need the very best for sustained throughput.

Still, SATA SSDs make sense since they can use the full SATA bandwidth and have low latency compared to HDDs.

So the (lack of) price difference is not really surprising.

No one was justifying or celebrating censorship then, and no one is screeching and screaming now.

It seems you're trying to imply that "progressives" are being hypocritical (although I don't know what specifically is "progressive" in this context), but there is no hypocrisy in recognizing that private platforms have the right to enforce policies while also protesting those policies. That's how free speech actually works.

As opposed to what conservatives were doing not long ago, which is demanding the government forcibly take over social media platforms and make banning them illegal. Talk about screeching and screaming.

It's easy to point at any one thing and make that the cause. More likely though it's a combination of things all working together.

Yes, the labor market is changing. As the economy changes from industrial to services, so demands for some jobs go up, others go down. The emphasis on automation (AI being just another card in that deck) means that more is produced, while employing ever fewer people.

100 years ago agriculture consumed 27% of the work force. Today its 1%, while at the same time production is much higher.

The explosion of student debt, the access to knowledge online (outside of a college course), the declining birth rate, the current hostility to foreign students, the poor image of the US abroad, all contribute though. Each factor is small in isolation, but together they're moving the needle.

The saturation of the professional class also plays a role. Do we need to churn out several thousand new architects every year? Especially into a society that sees the concept of architecture as irrelevant?

Yes, colleges will close. The demand caused by the boomers will go away. But that's part of a much bigger shift in US society.

Oh I did. I got rid of it. Inspiring both constant censure and the kind of response you're giving drove me to despair.

I don't write things for public consumption now.

But we're not talking about me or the post. We're talking about your refusal to engage with the implications of what the project did.

I don't care what Datastar does. I'd never use Datastar. Looks like exactly what I don't need. They can certainly govern their product as they see fit.

But I've disassociated from projects for less egregious unannounced terms changes. And I've never had that decision come out for the worst, only neutral or better.

Good luck with your future endeavors, I guess.

Try the EC2 creation page. There are tabs for advanced options, widgets like images selection that you can choose from AWS-managed, Community, your own AMI, etc. And then the next page is confirmation of similar widget which you can go back and edit. I'd imagine that if you render it in backend first and one of the tabs has error your backend form library has to know how to rerender all the widgets that you already implement in JavaScript once. If the page is done in SPA the backend just send the data back and the existing frontend widget just have to rehydrate itself.

Not at all. It applies only to institutions that are funded by the government. Receiving grants has been characterized as accepting government funding, which is strange on the fundamentals - those grants notionally represent the government paying for work it wants done.

Also characterized as accepting government funding is admitting students who get student loans from the government. This goes well beyond "strange on the fundamentals" - that money is notionally given to the student, not to the school.

For one thing, very few markets are like that, and even then they face the threat of new entrants if they suck. e.g. the cab companies that got blown out by Uber. You are right that they fundamentally operate the same way as state funded entities, but having a revenue stream that is completely divorced from providing economic value allows the institution to keep its doors open at levels of rot 10x that which it takes to kill a megacorp.

I was in and around multiple stations for a week, from early till late, and never saw a single one anything other than packed. Lineups up the turned off escalators topside were extremely common. Many tens of thousands of people were riding.

FWIW I was at the event that caused the worlds biggest event centre (the Vegas convention centre) to expand, because it wasn’t big enough to host the event.

Millions and millions of people in and around the convention centre, all serviced by the loop.

The new windowing system is actually rather decent when used with a keyboard + all window tiling / maximising / app switching keyboard shortcuts memorised. Although the lack of Slide Over is still inexplicable and sucks.

The issue is that most people don't use iPads with keyboards. The windowing system in this case is then an absolute nightmare compared to what came before, as touch-based users were clearly a distant second thought when designing it.

For any HNers who don't have access to iPads running iPadOS 26 / 18, and aren't sure if this is just the "people on the internet hating new things" reflex (it really isn't), here's a side-by-side comparison that clearly illustrates andix's point[1]

ZFS is a combination of actual file system like Ext4, LVM and MD (software raid) subsystems on Linux, with extra features on top which you unlock when these are a single system.

Due to licensing, it can't be included in Linux kernel directly, and so it's not seeing the same level of scrutiny like the rest of the kernel, but it is arguably used in production more successfully than btrfs (comparable feature set, in-kernel, but not maintained as well anymore).

They said the same about social media. Don’t conflate value creation with value capture. It can often lag, which creates the appearance of a bubble. To me, engagement through the roof and costs rapidly declining is the definition of value rapidly scaling up (scaling in this context specifically meaning reach going up while costs decline). Value capture is lagging behind but that doesn’t necessarily mean it’s a bubble. I’m certainly open to the possibility it’s a bubble, but that’s not what my firsthand experience is telling me or any of the aggregate numbers.

Even if it is transformational, who will realize the gains? AI service providers have no moat. We can all just run LLMs locally for a fraction of the cost.

Yes even an HDD can keep up with 1GbE.

But if you actually want your Ethernet to be similar speed to your SSD, you don't need to spend that much. Get some used gear.

32 port 40GbE switch (Dell S6000) $210 used

Dual port 40GbE NIC (Mellanox MCX354A-FCCT) $31 used

40GbE DAC 1 meter new price $22 or 40GbE optics from FS.com (QSFP-SR4-40G) $43 new + MMF fiber cable

Of course, that's probably not going to be very power efficient for home use - 32 port switch and probably only connecting a handful of devices at most.

Not sure about the LLM community, but it's not uncommon in other computer-science communities to assign common names to models and implementations.

Common names will always be influenced by the authors culture, so it seems unfair to exclude a name based on any individual opinion that it is or isn't a mundane choice.

Unless you would also exclude names based on their relationship to old, but culturally relevant texts in the western tradition to, e.g., the bible.

In my book a great school would likely have a low-ish acceptance rate. And so they could (even though they may not be happy about it) absorb some amount of declining applications by adjusting their acceptance bar. WKU's acceptance rate is like 95%. They're already taking ~everyone who applies. I question whether school quality truly plays no role at an institution which struggles to find a student they wouldn't admit.

OpenAI's (and other superscalers) revenue isn't really up for debate, nor is the long term value of their mission/product. The issue (somewhat articulated in this article) is that the superscalers (both public and private) have generated such a massive, unprecedented amount of speculative investment as well as capital expenditure that has left the rest of the economy in the dust (aka minting a mag 7 in less than a decade) that we have a distorted view of the world.

The fear of an AI bubble isn't that AI companies will fail, it's that a downturn in the AI "bubble" will lay bare the underlying bear market that their growth is occluding. What happens then? Nobody knows. Probably nothing good. Personally I think much of the stock market growth in the last few years that seems disconnected with previous trends (see parallel growth betwen gold and equities) is based on retail volume and unorthodox retail patterns (Robinhood, WSB, et. al) that I think conventional historical market analysis is completely unprepared for. At this point everything may go to the moon forever, or it may collapse completely. Either way, we live in a time of little precedence.

Hilariously naive comment - "if you have money you should spend it on salaries". This is not a charity, it's a transaction, the salary is paid in exchange for revenue generating activities or supporting activities in a viable business. If the business is only doing 2.7mill in ARR, then it's entirely valid for the whole lot to get laid off.
Show HN: I built a LSP with its own parser to learn Rust
by TheJuli | 2025-10-11 03:44:04+00:00
During my day job as a flutter developer, we use the Firebase stack as our cloud solution. The current landscape for extension support is lacking in the LSP department for this language. There are numerous extensions but all are modeled as VSCode extensions. So I set a goal to learn rust (and consequently building grammars with tree-sitter) by building a LSP that uses its own parser for the firestore language to enable type inference, diagnostics, linting, etc.

Its still in its infancy stage but at least there is an LSP in this space right now. As expected there is a vscode companion extension that simply wraps this lsp https://github.com/JulindM/firestore-rules-lsp-vscode

250M all-time users in a mobile game versus 800M weekly active users with scary native advertising possibility, is at least a two orders of magnitude, maybe three, difference in monetization.

The better comparison is Fortnite & Epic Games, which has ~1.5M concurrent players [1] and commands an estimated valuation of ~$18B [2]. You can also look at Meta, which runs platforms materially similar to OpenAI, with user counts within the same order of magnitude, and they command a valuation of ~$1.7T.

I would say the exact same for Google.

What isn't SEO'd to hell is crowded out by half a page of paid search ads.

I'm not a typical consumer though. I don't think I've ever bought anything via an ad.

The only search ads I click are the ones where Google FOMO-extorted the brand into buying ads for their own trademark. (That shit ought to be illegal given the monopoly levels of search capture Google has. Everyone having to buy up search clicks for their own brands and company names is comical. A protection racket.)

Ever needed to quickly remove the background from a logo or icon, only to hit a login screen or paywall?

I built this because I was constantly annoyed by other background removers — they wouldn’t let me download at full quality without signing up or even paying.

This one runs fully in your browser: no uploads, no tracking, no nonsense. Works great for logos, icons, and other simple images, and you can download the result at full quality instantly.

From Wikipedia:

> A digital twin is a digital model of an intended or actual real-world physical product, system, or process (a physical twin) that serves as a digital counterpart of it for purposes such as simulation, integration, testing, monitoring, and maintenance.

> A digital twin is "a set of adaptive models that emulate the behaviour of a physical system in a virtual system getting real time data to update itself along its life cycle. The digital twin replicates the physical system to predict failures and opportunities for changing, to prescribe real time actions for optimizing and/or mitigating unexpected events observing and evaluating the operating profile system."
by jvkoch | 2025-10-11 03:50:18+00:00
A 'digital twin' is a model that evolves over the lifetime of a physical asset. So if the state of the real device changes, so does the model (data assimilation). Likewise, one can use the model for control/planning/"what-if" scenarios. This is the bi-directional information flow that's being mentioned.

So what I'm showing on the website is just the model part. I'm not a fan of exposing my hardware in a public demo (the digital twin part), but the idea is that this model evolves with the roaster during the roast (data assimilation) and can help the operator guide the roaster to a desired end goal (e.g. medium roast along some profile or with minimal energy usage).

Your assumption is sometimes incorrect as cheap devices can share some RF front end. Also apparently resource contention can also occur due to CPU, thermal, and memory issues.

This is a really cool project and I’ve been following it for awhile. I’m also keen on breaking up the code forges monopolies.

I’ve been dipping my toes into this space mainly because I think code forges as they exist are trying to solve multiple problems at the same time. I think there’s value in splitting this functionality up into discrete services.

For example, most forges: host your git repo, web view, collab tool, ci/cd pipeline, and task management.

I don’t see why these necessarily need to be bundled together.

For example, as long as we are comfortable not having direct access to the git repo, we can have a purely static web viewer for git: https://pgit.pico.sh

For collab, as long as we are comfortable sharing patchsets and reviewing locally, we can have a collab server that doesn’t need a git repo in order to function: https://pr.pico.sh

Then self hosting your own bare git repo on a VPS is trivial.

Git is already decentralized, centralizing it because all the other services require it is the anti pattern

> it’s always been unfashionable to kill someone, to lie, to display envy, and so on

Even if we restrict ourselves to recorded human history, there are plenty of examples where killing in particular and imposing one's will by force more generally was glorified.

This is really a very modern development (last hundred years?). Just look at how women have been treated 50 years ago as the "weaker sex" (and to an extent, still are today).

But going back to morality of the Western world, how does that compute in terms of recent excursions in Palestine, Iraq, Afghanistan, Syria... All exceptions needed in the last 20 years?

My point is that I subscribe to the notion that "morality" has been developed as a human, reasoned construct to help with self-preservation when cohabiting in large social groups (aka civilization) — I am outright disagreeing with you. Compare with the "morality" of humans brought up outside society (kids lost in woods and similar). Too many counter-examples throughout history to consider it innate, IMO.

"Open" "AI" defines a weekly user as someone who has used the service one time in a week.

250M for Angry Birds is not all time users. They had 260 million monthly active players:

https://yourstory.com/2025/02/rise-fall-angry-birds

Who got bored later, as is the case for "AI" already now. I agree though that monetization of people entering their private data is much more promising for a company with ex-NSA directors on the board.

Still, I believe that "Open" "AI" is completely overvalued.

A bit more simple. An MCP server and an interactive command line tool for CLI. It is written in python. Feel free to check it out. The system exposes the tools to the agent to use, it doesn't do any type of context adds automatically. It can link the memory system from any MCP compatible client. So claude desktop and claude code can see the same memories. Or you can use different MCP servers for each instance..just move the folder and update the username/agentname.

One of the few social media outlets that didn't blatantly censor Israel's war crimes. So of course it had to go. Places like Hacker News are safe because they toe the line and ensure "inconvenient topics" aren't popular or promoted.

An example of a purchase I made recently is this $15 bimetal heat break: https://www.amazon.com/dp/B0C5VSK1V8 it's basically a part that allows you to 3D print at higher temperatures. To figure out that this was the right product I wanted, it took a couple minutes of research, looking at diagrams, searching recent reddit and youtube posts, etc.

If I would have asked an LLM, it would have told me to buy an all-metal hotend that costs $70 or more, based on outdated advice.

I don't trust LLMs for out of the box thinking because they have no idea what is going on in the real world. They are fine for discussing general aspects of well-documented and often-discussed things like taxes, cooking, or gardening.

Games have tons of opportunities for parallelism (outside of rendering which is obviously embarrassingly parallel) if they are designed for it from the getgo. Unfortunately, most game engines make decisions up front that force much of their game logic to be inherently serial for no good reason. It is definitely true that the sort of parallelism you get from architecting for it from the beginning bears little resemblance to what a compiler would be able to extract with an automatic semantics-preserving pass.
