Ah, I see what you're getting at. My instinct here is that (exactly as you've pointed out) fields like E and B will fall off like 1/r instead of 1/r^2, but that all of the qualitative behavior will be basically the same. So I wouldn't trust this simulation to predict the precise behavior of a real circuit (even one whose shape was basically planar), but I suspect that it will behave more or less right.

Looking at the examples, it seems like you can make 1D and 2D strings/grids of resistors here in much the same way you would in a 3D model; you just can't make a 3D grid (or non-planar circuits). My general experience working with and teaching basic circuits is that it's rare that we consider current flow in a genuinely 3D medium: the vast majority of problem-solving examples approximate wires as simple 1D paths for charge to follow, and more careful treatments that talk about where charges accumulate to guide current flow around corners, etc. still almost always illustrate their points in 2D diagrams/examples.

So my impression is that this simulation is likely to give a pretty solid qualitative sense of how these systems work, despite its 2D framing.

Your website looks good, if I were in the market for such a solution I'd probably consider yours ?

But as someone already said, you maybe need to focus on solving a more specific problem or vertical, rather than being all things to all people. To find it, naybe think back about why you built this in the first place?

A more minor point : I would trust you more as a customer if you added an About page, to put a face on your product.

> So why specifically are people allowed to build on humanity's past achievements, but not AI?

because those people seem to think that individuals building it will be too small a scale to be commercially profitable (and thus the publisher is OK to have them be a form of social credit/portfolio building).

As soon as it is made clear that these published data can be monetized (if only by large corporations with money), they want a piece of the pie that they think they deserve (and not getting).

This is some serious cherry-picking at work.

Look at the NIH grants listed, which by dollar value far outweigh the NSF grants listed: https://grant-watch.us/nih-data.html

Which part of preventing the spread of HIV is "left wing politics"? Or better understanding radiation exposure? Or developing anti-viral countermeasures?

Some $400m of remaining budget for preventing the spread of HIV was cut, and you're saying it's justified because less than $3m went to trying to improve professional development for a specific group of people?

I mean even look at the specific example you picked - $2.8m over 6 years, from 2019 through to an expected end date of 31 August 2025, and they cut the funding on 09 May 2025 - the work has already been paid for and done, and you want to cut funding so you don't even get the final report/publications out of it to, you know, have something of value to show for the money spent?

I made some GGUFs at https://huggingface.co/unsloth/INTELLECT-2-GGUF

./llama.cpp/llama-cli -hf unsloth/INTELLECT-2-GGUF:Q4_K_XL -ngl 99

Also it's best to read https://docs.unsloth.ai/basics/tutorial-how-to-run-qwq-32b-e... on sampling issues for QwQ based models.

Or TLDR, use the below settings:

But also an appeals process where it can be escalated to a real person. There should be nothing where any kind of AI system can make a final decision.

I think the safest would be for a reviewer in an appeal process to even not have any access to any of the AI's decision or reasoning, since if the incorrect decision was based on hallucinated information, a reviewer might be biased to think it's true even if it was imagined.

Well I think a very strong heuristic is that anyone who uses the term latinx is a race grifter. But that aside, the important point is that these cuts appear to be in stuff that is at least arguably not very scientifically important. I don't see any cuts to studying magnetism or cancer or distant galaxies. Tellingly, the article doesn't say "Oh no Trump is cutting our latinx cultural competency grants!" it is pretending that basic science is being cut and hoping you don't notice. So the article is dishonest and dumb.

Vile ideas are not automatically accepted as 'valid information'. You're assuming that society can't handle challenging ideas while ignoring the possibility that free speech is what allows for those ideas to be openly criticized, debated, and disproven. A robust system of free speech is what actually ensures bad ideas are not given a free pass but are subject to critique and debate

Most websites only explicitly deny scraping by bad bots (robots.txt). Things like Cloudflare are a completely different matter, and I have a whole batch of opinions about how they are destroying the web.

I'd love to compete directly with OpenAI, but the cost of a half million GPUs is a me problem - not a them problem. Google can't be faulted for figuring out how to crawl the web in an economically viable way.

I agree, and I am as guilty of procrastination. However, the author is not really procrastinating—he gets paid for this. Me, I do in fact procrastinate on setting up a Minecraft server infra in the cloud. Maybe that’s precisely why the solution to this problem strikes me as inadequate:

> So, the Minecraft server should work reliably and, if it goes down, I should know well before they do

How are metrics helpful? There is so much fun that could be had in setting up an actually resilient system instead.

Why worry over metrics and alerts when you could orchestrate an infrastructure that grants you the superpower of being able to spin up a server with a copy of the world on a whim instead (or even a system that auto-starts one whenever there is demand)?

Here's what works for me:

1. Already found X highly motivated scientists and engineers.

- in my case people that must like chemicals, electronics, software, stuff like that

2. $1Mil funding x X but it's got to be paid back in 5 years so a viable business model needs to be initiated right away even if the technology is as much as a year out from possible release or commercialization.

- each person needs to be worth a million over 5 years, that's hard enough to find, it would be more of a needle in a haystack to find experimentalists where it's good to sink a million per year for a decent length of time, but that can be worked up to. If serious research is involved, stealth must be an option

3. Put them in X number of buildings.

- works better than you think, and "nobody's" doing it

4. Some of these are profit centers from day 1, so you could even put franchising on the table ;)

- you'd be surprised what people who've already invented a lifetime of stuff could do with the kind of resources that can enable a motivated creator who has yet to make very remarkable progress, so leverage both

I just took the first one from the list. The list the article gave. I didn't cherry pick anything. The general theme of the titles of the research grants makes me think that the ones with more innocuous sounding titles are actually just more of the same stuff, just disguised a little better. But I could be wrong. I'd love to see an example of some indisputably important research being cut.

And I dunno if you're being pollyannish or what but HIV research is often very tied up in left wing politics. It may or may not be in this case. For example: https://www.nbcnews.com/feature/nbc-out/new-california-law-r...
Ask HN: Pipelines with WASM Components
by mootoday | 2025-05-12 04:59:03+00:00
Hi HN folks, I've been digging into Wasm components for the past few days.

I find the idea of it being language-agnostic intriguing, not to mention the security aspect of how components are isolated at runtime.

I'm considering to build an open source solution to run pipelines based on Wasm components. For one, to learn more about the technology, but also to potentially provide a hosted solution to sustain the open source effort.

A web UI to create pipelines / workflows and a runtime that orchestrates and executes pipelines. People add nodes to a canvas and each node maps to a Wasm component.

I'm curious what you think of that. Is it something you could use? Is it a waste of time because it already exists? Any feedback welcome.

Thanks

"Here's a small number of things that will die when Google dies."

How many were developed by Google; how many were Google acquisitions.

These "arguments" are so weak, so desperate, they only expose Google's culpability even further. Silicon Valley routinely obfuscates, misdirects and even lies under oath. It's difficult to make convincing arguments absent any credibility.

Which is exactly the thing they tested multiple times and found to be wrong.

People get bored doing nothing, and enjoy contributing to their community.

No, they're not going to go get shitty factory jobs. But that's OK, because all those jobs are now automated and done by robots.

But they are going to go and do something useful, because that's what people do. The anti-UBI trope that "given basic income, everyone will just sit around on their arses watching TikTok videos" has been proven wrong in every study that measured it.

> I'm using "liberal" very loosely here as the prevailing political establishment from the 1930s to 1990s when the Republicans started splitting off from that coalition.

It becomes meaningless. You just rewrote history - the GOP was apparently liberal all that time. Who knew? The actual liberals sure didn't; they despised Nixon and Reagan. You're just saying that the modern rightward lurch is somehow the reality of the century before it happened.

> A degree can either be a ticket to a high status job or common.

You still are framing it around jobs.

> only the ones from exclusive, high status schools count

The overall average income for people with college degrees is much higher. That can't be because of the few who went to elite schools.

> So you are telling me that in 1960 when 8% of people had a college degree, those 8% were a meritocratic sampling of all classes of society, but today when 40% of people have a degree, that 40% is somehow only the upper middle class?

The leading predictor of college education now is your parents' income.

I can't say whether he was or wasn't a narcissist, because I can't really tell one way or the other, but I don't think he had a simple inability to pick up on social cues. At least, that doesn't look to have been the cause of the abrasiveness. To me, it just seemed like he believed that people could do better.

This video is just one tiny piece of history, but I'd call it a very good watch: https://www.youtube.com/watch?v=8-Fs0pD2Hsk

Today's Apple doesn't truly stand for this anymore. Today's Apple is not the same Apple. It still has Jobs' Apple in its core, and that's why there ever was a solid base to build upon... but their new stuff is all hit or miss, sometimes very miss, because they're not the crazy ones anymore. They're slowly rotting into a generic megacorp... and that is very sad.

I have a number of concerns with CSU Ft. Collins. I know people who transferred to Billings because FtC was losing accreditation in some majors. (This was years ago.)

FRCC only offers machining in Boulder Co. Welding (only mentioned because that’s what this tread is about) is offered in Larimer though.

I know of several job opportunities today in the northern part of the Front Range that need toolpath programming.

The kid built a CNC router for his HS FRC/FTC club as an Eagle Scout project, then ended up at Mines.

p.s. We have 100 series product now.

Currently the OECD average spending on R&D is ~2%. Let's say half of that is government spending.

The OECD's total GDP per year is ~50 trillion. So 1 percent is roughly 500 Bn on research.

So there clearly has to be some accountability. But no doubt it could be improved. As you say publishing everything these days makes more sense with platforms like arXiv.

With taking pay cuts to do research, have you ever seen places offer part time work for something and then allow people to research what they want in the other time ?

Or researchers just doing this with other jobs ?

Ha. Hmm. I just realised I have a cousin who does this.

> silence is interpreted as consent

silence is indeed concent (of the status quo). You need to vote with your wallet, personal choice and such - if you want to be comfortable, choosing the status quo is the way, and thus consent.

There's no possibility of a world where you get to remain comfortable, but still get to have a "choice" to dictate a choice contrary to the status quo.

I'm someone who repairs a ton of things, but consumer 3D printers aren't practically useful for the majority of repairs. Injection molded plastic is significantly stronger than consumer 3D printed plastic (yes, even ABS.)

What that means is that if the original part breaks, the replacement will break too. Even if you just go for equivalent strength, the replacement has to be significantly larger and in many cases is simply not possible (as printed objects are quite weak along layer lines.)

I'm sure there are all sorts of counterexamples people have posted online, but the evidence is out there. Look at thrift stores or eBay or whatever. You can find plenty of objects repaired with traditional methods (epoxy, fillers, metal plates, glues, rivets, screws, plastic welding, etc) but I have never come across any used items repaired with 3D printers.

Perhaps in five or ten years we'll all be printing high strength nylon or continuous fiber parts at home, but for now I'm chalking this one up to marketing.

Operating margin is irrelevant, only profit margin matters for this context. Walmart hangs out in the 2.5% to 3.5% range, not materially different than Mazda. Either way, any business with a low single digit profit margin is not making money hand over fist. It might be different if Mazda had such a huge and loyal market share that their low profit margins are offset by low volatility of expected future sales (such as with Walmart/Costco), but that isn't the case at all with Mazda.

Their expectation is that their sales will be stagnant at best, but probably decline for the foreseeable future.

The lack of food can be explained either by a shortage of demand or a shortage of supply. Many people assume that the demand is there and the supply is the problem - people are desperate for healthy food but no one wants to sell it to them for some reason (the reason is always left unsaid). Instead, they have no choice but to shop at 7/11. So presumably, as soon as a store selling fresh, nutritious ingredients opens up, it would be swarmed with people buying broccoli and chicken breasts. However there is some evidence that the reason no healthy food is being sold is because people's demand for heathy food is being provided by a supermarket a few miles away, or that they just have little demand for healthy food in the first place. Here is an article with more information: https://www.nyu.edu/about/news-publications/news/2019/decemb...

You are somehow very negative about this piece and are not understanding that your definition of fun is not universal.

As you said "There is so much fun that could be had in setting up an actually resilient system instead.", maybe the author has more fun setting up alerts and metrics instead of a resilient system like you do?

The truth is that in most real-world scenarios getting alerts, metrics is much more important than building a fully resilient system (Expensive, maybe overengieering for early stage etc.).

> However, the author is not really procrastinating—he gets paid for this. As the first sentence in the blog post says "One of the secret pleasures of life is to be paid for things you would do for free.", which I can very much understand as I often work or play with things I could use at work in my free time.

The biggest problem with burrito loans is that they are selecting for sub-prime borrowers. Someone who needs to explicitly finance a burrito is much more likely to be a sub-prime borrower. Just like with the sub-prime mortgage implosion, the product of securitized junk is junk. At least it won't be a systemic risk this time.

I have been there and done that. Sent LinkedIn messages but never got any response. I understand where you are coming from. I do.

Then I reflected on that and thought about the many times I rarely responded to any LinkedIn messages sent by someone who I have not met or had no common connection what-so-ever. I realized everyone is busy and also may not want to spend any time or energy on someone who they have no connection - or want to protect themselves from potential spammers.

What is in it for them? - That's the hard truth that rarely anyone wants to spend any time or energy on someone who they have connection. It doesn't matter if you are from the same school, city or an entrepreneur like them.

Up to N at a time probably. Then move on using them. The problem is the longer the chain, the more likely it will deviate from the reality. It will include non-obvious atomic decisions and wrong assumptions. This will make the whole thing unstable. I.e. without strict human supervision it likely will start producing crap. Probably some self double checks can help, but still. On the other hand humans aren't that smart either...

As someone who grew up in Michigan, I should note that most Michigan lefts do not involve a median nearly as wide as Hall Rd. Most are much more reasonably sized. What Hall Rd is doing also isn’t that new or unique around here. This setup is extremely common all over the Detroit area and has been for as long as I can remember.

I spent a few years in the Chicagoland area and found myself really missing the Michigan left, as people in Chicago just do random U-turns. When I tried asked the locals the rules/laws around them, since U-turns in normal roads aren’t really a thing in Michigan, they just kind of laughed. I’m not sure anyone knew.

That said, they aren’t perfect. The biggest issue I have is when they aren’t used consistently. If the N/S road and E/W road both have them, great, there are lots of options. You can turn right, then flip around, or go through the intersection, flip around, then turn right. However, if one road doesn’t have it, then you don’t know what to do until it’s too late. GPS makes this easier, but back in the 90s you just had to know the area.

My other minor grip is many of the median have various obstructions… a hill, trees, bushes… which can make it hard to see oncoming traffic, which is an issue when all you have is a stop sign.

That said, they are still better than your standard stroad… and we still have a lot of those too.

The twitter criticism is getting funnier.

https://x.com/zackkanter/status/1920284851506225498 criticizes 37signal of missing an opportunity because they focused too much on reducing COGS. An example opportunity that this guy gave is really really random. As you guess it, it's the AI opportunity cost. Because 37Signal hasn't integrated any AI. That must be a loss! Of course, it's the AI again!

https://x.com/grinich/status/1920636351139230043 (from WorkOS' CEO) criticizes 37Signal of not growing and losing to Jira and Linear because 37Signal focuses on saving a couple millions of dollars a year.

Jira isn't even profitable after all these decades of "winning". It's a project management tool. What do they even spend money on?

Linear is one of its kind startup. Is losing to Linear that bad? I too want to lose to Linear and make >$10,000,000 a year with my product.

The response from DHH is perfect tho: https://x.com/dhh/status/1921075541672612294

"Problem is that nobody seems content to merely put their dent in the universe. No, they have to fucking own the universe. It’s not enough to be in the market, they have to dominate it. It’s not enough to serve customers, they have to capture them."

Not only that, project management tool's market is fragmented. It'll never be a winner-take-all given there are hundreds of use cases / settings / industries. It's going to be extremely difficult to be Number 1. Investing in growth would kill you. Reducing COGS and staying profitable is the best way IMO.

I skimmed through the paper and the code and got the same conclusion.

It’s overhyped, filled with marketing language.

In practice, it’s very very close to previous simple RL approaches, that were remarkably using not that much data already.

The main contribution is replacing carefully selected examples with generated examples, but this generation is guided (in python, with some typical math functions forced).

It’s akin to replacing some manual tests with mutation testing.

Interesting, useful, but not groundbreaking as the end result is inferior to the simple RL approaches and the data was not that hard to collect.

It is an interesting approach to generalize to other domains where there might be less data available or less easy to curate

Tesla was eating their lunch in terms of software, integration, capabilities, apps. Then rivian came along and a few other companies doing a much better job than the awful legacy companies.

Now of course tesla/musk are destroying themselves through various idiotic actions. Sales are dropping through the roof. But the technical quality of the software ecosystem (car, web, app) is still better than all the incumbents. Think about Rivian getting a billion dollars from VW for their much better ECU and and software integration, for example.

I feel like Rivian is almost as good as tesla. Tesla still has all that, even as the company is in awful shape sales wise. Lucid seems to be better than the legacy auto, but I haven't looked into it as closely.
