> slow moving cargo bike has a lot of potential kinetic energy

Not as much as people tend to think, our intuition usually underestimates the importance of that squared velocity component. To illustrate, here are some vaguely-plausible numbers from some quick web-searches:

* A 65kg (~143 lb) person rides a big-bucket cargo bike of 65kg with 100kg of cargo, or 230kg total, moving at 5m/s (~11 mph) for 2875 joules kinetic energy.

* The same person on a 25kg passenger bike traveling at 10m/s (~22mph) is 4500 joules.

To be equal, the second rider would have to slow down to about 8m/s.

> a normal human reaction time can deal with it

True, it's easier for an alerted person to leap out of the way of a slower vehicle... but I think if everyone involved was perfectly alert and poised for action, we probably wouldn't be having this conversation.

Sam will definitely know more about this than I will, so if he contradicts me, listen to him.

If I am not mistaken, the racket language does not convert to CPS during compilation. Instead, when you want to get the continuation, I think you just get a pointer to the stack frame that you want. All I know for sure is that it uses something called a-normal form, which is kind of like SSA in some ways, and that the continuation is 2x 64/32-bit words depending on your architecture.

Can someone clarify the patent? Most discourse I've seen outside this website regarding this focuses on parts only listed in non-limited examples (like ball throwing). I don't think that's relevant at all here (except claim 10).

The main text from what I understand is the claims in sections 37 to 41. Claim 1 is what I'm understanding the be the main claim, which can be summarized as summons that can either do manual combat or automatically battle after following a player around/being directed.

The other claims are to be taken individually, correct? If not, claim 10 (requiring attack of sub character and option for capture) would disqualify most non-capture games and would likely make this a non-issue, but if just the first claim needs to stand then this would be really broad (and from what I understand, prior art in that space would be easy to point to).

i recognize freedom (especially as it relates to commerce) is a social construct and therefore has limits defined by society. At the same time, it does seem like in this instance at least the EU wants to have it both ways: ie it wants to be seen as operating on high-minded “principles” yet be allowed to justify fairly transparently self-interested industrial policy actions under the guise of “protection from monopolists”.

> It’s interesting that the U.S. picked an employer-driven model...

Health insurance, parental leave† and retirement are also employer-driven. This seems to be a US default that incidentally gives a lot of leverage to employers.

† Yes there are government mandated minimums, but when compared to other developed countries, substantive parental leave is largely left to the generosity of the employer

In the past, having to work with Indians from firms like Cognizant or HCL is pretty much torture. Instead of working with 2-3 Americans, you get stuck working with 10-20 Indians who dont know jack shit about shit.

Thankfully the company recently nuked their contracts and brought everything back on shore because of how much of a shit show dealing with those companies is lol. Literally tens of millions of dollars wasted.

Im kinda convinced that's their entire business plan. They lure these mega companies with omg "skilled labor" and having to pay them less, sign XX-XXXM contracts, 2-3 years go by and these mega corpos finally see how shit it is and just cancel them. HCL and Cognizant make money still regardless.

In one video I've seen UTM used mouse emulation without absolute positioning: it treated the screen surface as a giant trackpoint nub and you could move away from the current location with variable speed. A native on-screen keyboard is also available.

For absolute positioning a USB input device is emulated, so this might not work in Windows 98 without a suitable driver: https://docs.getutm.app/preferences/ios/#cursor

> After a while you start to realize that there's a whole world of people just like on HN and we hire people too. No matter what you do, youll end up in the place you deserve.

I mean, I'm hoping for that too. But it also feels like this only applies as long as there's a balance of likeminded people who are already in the industry vs. the people looking to get a job. For someone like me, without a real network, meeting a person like the kind you mention is extremely unlikely. Even then, most of these people are looking for more qualified candidates, since there's an overabundance of juniors and seniority is a good predictor for being really passionate about their field. So, maybe I'll figure that out someday, but right now I just need a job, and what people in my cohort do is a way to try and get a job at all costs.

Or... those other parts of the economy increase salaries for skilled labor?

If we can only bring 85,000 people into the country on one type of visa, doesn't it make sense to prioritize those that will bring the most value (tax revenue, in this case)?

And if that's not enough people... raise the limit? And be confident that a raised limit is still keeping a high quality bar on entrants?

I gave Meow a fair shake a year or so ago. I'd say it's currently the most robust mode for implementing Kakoune or Helix-like bindings in Emacs, but you can customize it to be like vim or anything else. It's more lightweight than evil-mode. At present, however, I'm not using modal editing in emacs; just lots of Meta-key shortcuts for movement and a hydra with a key-chord for common commands.

So you’re admitting that applying for jobs they should be able to get, in a place they should be able to apply in, under federal law is not going to work?

Sounds like fraud to me. Or a crime of some sort.

If they do it, and it clearly doesn’t work, it even sounds like something they could take to court.

In fact, something that is perhaps their duty to take to court.

True, they haven’t stored any waste yet but the facility is completed.

And depending on how you look at it, it could be 100,000 years before you know for sure if it works, so my claim that it’s a ‘solved problem’ is a bit strong. I’ll retract that and say that it’s the most promising idea for nuclear waste disposal, one that that is close to beginning operations.

> If it didn't actually work, it would've been discarded by companies long ago

You're assuming that something else works better. Imagine if we were in a world where all interviewing techniques had a ton of false positives and negatives without a clear best choice. Do you expect that companies would just give up, and not hire at all, or would they pick based on other factors (e.g. minimizing the amount of effort needed on the company side to do the interviews)? Assuming you accept the premise that companies would still be trying to hire in that situation, how can you tell the difference between the world we're in now and that (maybe not-so) hypothetical one?

The year-old iPhone example is misleading at best, if you take this guy at his word on having "driven into the ground" multiple cars. If you don't believe him on that front, I see no reason you'd believe anything else in this essay, anyway.

We should ourselves and should encourage others to effect less waste in our world. We should not compare someone apparently doing so to those who clearly do not.

> if you think that's some kind of gotcha, it really isn't

It's not supposed to be a gotcha. It's supposed to be "너희 중에 죄 없는 자가 먼저 돌로 치라"

If Korean SPUs can treat Mongolian, Thai, Viet (my SO is Viet and has family who are "trainees"), Nepali, Indonesian, Pinoy, and other migrant workers that way, it is a bit of schadenfreude which I hope will be used to Korean society to better treat migrants.

> What kind of idiot invites a multinational corporation to build a factory in its own hometown, and then arrest workers when they show up to build it

Why couldn't Hyundai and LG file an H-2B [0]? That's the correct visa for migrant construction and manufacturing workers. Abusing the B1/2 and VWP program is not the right way to do this and frankly, is extremely amateur and shows a sense of disdain for our laws.

The European and Japanese companies like VW Group, Stellantis, and Toyota haven't had the same history of visa abuse that Hyundai Group and LG Group have had in the US.

If they can stand up EV and battery factories without the same persistent abuse and flouting of OSHA regulations, why can't Hyundai Group and LG Group?

> So does the US want this factory built or not

I am a big booster for US-SK relations, but we want your chaebols to follow our labor laws if you want to build here.

I've worked closely with the Korean policymakers, and had good friends who worked closely on the Biden era deal to help bring Korean FDI into battery tech and shipbuilding (my thesis advisor from undergrad helped act as a mutual negotiator for the US and SK), and even gave some advice to 박영선 on her semiconductor strategy, so I absolutely want the relationship to succeed, but we are not Vietnam or India where you can demand special privileges or flout labor laws due to FDI.

The Japanese and Taiwanese conglomerates comply with US labor laws, as has Samsung and SK Hynix. It's only Hyundai Group and LG Group that has had a persistent history of labor abuse in the US.

By every standard, we should have banned and sanctioned Hyundai Group after their persistent child labor scandals in Alabama [1], but under political pressure we let them remain because of HD현대중공업

This keeps coming up every so often and most commenters on HN are completely ignorant of how the immigration system works, but have strong opinions about it, therefore it seems that everything is nefarious.

The real problem here is that the way the current system is set up, you have to prove that there are no citizens available for a position by listing a job and interviewing candidates. The problem with that is that you will never be able to prove that by this method. Say you have 1000 jobs for a specific role in the economy and 700 US citizens qualified to do that job and are already employed. The minute you try to file PERM for the 1 foreign national, if you list the job out, the chances of at least 1 person applying out of the 700 are very high because, you know, people change jobs. This puts companies and immigrants in a very difficult position because you literally cannot prove the shortage at an industry level on your own using this method. So they just have to resort to working within the laws to make it work.

This all would be completely unnecessary if congress fixes the immigration laws and asks BLS to setup market tests that are data driven to establish high demand roles.

Please don't post in this inflammatory style on HN. You've set off a whole flamewar – nearly 100 comments so far – with many of the comments debating the definition of racism. This is the last thing we need here.

The overall topic is important, which is why it needs to be discussed with comments that are thoughtful and substantive, which the guidelines clearly ask us to do:

Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.

Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

Please don't fulminate.

Eschew flamebait. Avoid generic tangents. Omit internet tropes.

Please don't use Hacker News for political or ideological battle. It tramples curiosity.

I'm a nuclear supporter. I think we might be able to satisfy our energy needs with renewables. I am not entirely sure, because I'm not in the field. But, if it's true that renewables are so much cheaper, then self-interested individuals will invest in them. There is no need to be anti-nuclear.

People like me, who are pro-nuclear, do it because they believe that nuclear technology, like all technologies, could become much cheaper. Elon Musk was saying about rockets that in the end, with enough learning, the cost of building a rocket is only limited from below by the cost of the raw materials, so he though there is room to make rockets cheaper by a factor of 10 or 100. I think nuclear technology is the same; we can make it cheaper by a factor of 10 or 100. After all, we did that with solar and wind, didn't we?

I've been on Zoho for my (and my partner's) email for 4+ years and it has been great. Chose them because there is no per-domain charge, so I have like 12 domains on it.

The configurability is extensive in both web app and ios email app. Service has been fast and stable. They rarely change anything in the UI (no random tinkering is what I mean) so it is predictable and easy to use.

> As someone just starting out, the general feeling among my peers is that I must bend to the interviewer's whims, any resistance or pushback will get you rejected.

But interviews are bidirectional. The company is deciding if they want me, and I’m deciding if I want them. If I chose to use Self or Forth as the whiteboard context for the conversation we’re having, it’s deliberately to make the interviewer think, and hopefully learn. If the experience of thinking differently about a problem (that they chose!) and learning something new is a negative signal to them, that’s fine —- it being a negative signal to them is a negative signal to me, and I don’t want to be there anyway! If they’re excited, and intrigued, and give “12 o’clock” feedback — well, that’s the team I want to work with. So I’ve helped us both accomplish our goals (making accurate assessments about fit), and aligned our metrics along the way.

Disagree. Most people don’t care about blog posts. Most of those are for SEO. It’s the beginning of a pipeline that flows from multiple endpoints.

A person can directly enter in the url that’s one endpoint. Another person can do a Google search and fine the blog that’s another end point.

All of those flows funnel the person in a singular direction with a single purpose: a purchase. Like what else do you want the customer to do? Go off on a tangent?

You can have multiple flows that loop back to a purchase but it’s much less predictable that way. Better to have a singular proven flow all the way to a purchase and that flow has to provide clarity on what the product is.

I come to the posthog website and I’m confused. This is a toy. It’s cool I can meander around and in time discover what the site does. I mean it’s ok.

A better site is one where I just look at the site I know what it’s for and I know the product. As I scroll down I see other tidbits or widgets that are like testimonials or proven examples and other things that convince me to buy. Finally I hit the pricing page.

That’s a better way to sell. Post hog is a cool site but not an efficient one. Not an efficient site for selling a product.

> and maybe some light training/setup/integration.

What do you mean by "maybe" or "light"? That's an explicitly permitted activity:

> A B-1 visa may be granted to specialized workers going to the United States to install, service, or repair commercial or industrial equipment or machinery purchased from a company outside of the United States, or to train U.S. workers to perform such services.

https://es.usembassy.gov/visas/commercial-industrial-workers...

Modern factories are filled with machines the size of buildings, making that installation sometimes hard to distinguish from the forbidden "construction". It's possible that some of those Koreans were unequivocally on the bad side of the line, but I see zero possibility that the agents could have meaningfully assessed that in the time between beginning the raid and taking the workers away in shackles.

I feel like installing equipment is widely considered to be an illegitimate use of B-1 visas, despite this explicit guidance. I don't understand why. I see from your comment history that you were a US diplomat. Is the internal guidance you received different from what's published?

I'm using mcp-agent and have tried the orchestrator workflow pattern[0]. For deep research I'm having mixed results. As far as I can tell, it's not using prompt caching[1] with Anthropic models, nor the gpt-5 responses API[2], which is preferable to the completions API. The many MCP tools from a handful of servers eat up a lot of context. It doesn't report progress, so it'll just spin for minutes at a time without meaningful indication. Mostly it has been high cost and high latency without great grounding in source facts. I like the interface overall, but some of the patterns and examples were convoluted. I'm aware that mcp-agent is being worked on, and I look forward to improvements.

Yes, something like this would be great. You could tie the registry to both IRS and SSA databases ensuring a) the job hunters are real, and b) the jobs offered are (eventually) real. It would also be great to carve an exception into liability law and require employers to give feedback to workers about a rejection. I'm sure this leaves lots of room for malefactors on all sides, but it would handle the biggest flaws of the current system.

The costs of cleaning up Fukushima, including the wider effects on the Japanese economy, are estimated to exceed US$200 billion. That makes it a pretty EPIC disaster in economic terms alone.

Even Chernobyl was not really that bad in terms of lives lost. Even taking the worst estimates of long-term deaths from radiation exposure, it killed a tiny fraction of the numbers of people who have died from hydroelectric disasters or from exposure to coal power plant pollution. But that doesn't mean it wasn't a catastrophic disaster for the regional (and wider Soviet) economy.

Show me the reduction in cost for medical care when 1/4 of the doctors in the US are foreign born medical grads, the bulk of whom came through the H1B program.

Show me the American born doctors on the street going hungry while foreigners take their jobs. Show me the reduction in wages or costs.

> supply and demand seemingly do not apply. Wages in tech engineering, and housing costs.

Were drowing in data on both of these things and if you want to understand either of these markets from an economic standpoint then your going to need more than a surface level "supply and demand" argument when they look much more like "I, Pencil" levels of complexity.

Im going to say this bluntly, every terrible engineer I have worked with, who has been fired for being bad at their job has been American born and raised. We're not importing dead wood and dummies to fill in roles as cogs on the h1b program. These are smart people who end up in high level roles who end up staying and becoming Americans (agin raising the bar).

>political violence is a cornerstone of this country since day 1

The violence was tame compared to something like the French or Russian or Chinese Revolutions. For example, after the Continental Army and Minutemen surrounded the Brits at Saratoga (in New York State) in the first of the two great victories made by the American revolutionaries, the Brits were not killed or even made prisoners of war: many thousands of British soldiers were allowed to travel on foot through Massachusetts to Boston (which was firmly in the control of the Brits for the entire duration of the war) if they promised not to harass any Americans in their path and if they promised to stop participating in military action against the American colonies (i.e., to personally go back to England).

Does continued scaling of large language models (LLMs) yield diminishing returns? Real-world value often stems from the length of task an agent can complete. We start this work by observing the simple but counterintuitive fact that marginal gains in single-step accuracy can compound into exponential improvements in the length of a task a model can successfully complete. Then, we argue that failures of LLMs when simple tasks are made longer arise from mistakes in execution, rather than an inability to reason. We propose isolating execution capability, by explicitly providing the knowledge and plan needed to solve a long-horizon task. We find that larger models can correctly execute significantly more turns even when small models have 100\% single-turn accuracy. We observe that the per-step accuracy of models degrades as the number of steps increases. This is not just due to long-context limitations -- curiously, we observe a self-conditioning effect -- models become more likely to make mistakes when the context contains their errors from prior turns. Self-conditioning does not reduce by just scaling the model size. In contrast, recent thinking models do not self-condition, and can also execute much longer tasks in a single turn. We conclude by benchmarking frontier thinking models on the length of task they can execute in a single turn. Overall, by focusing on the ability to execute, we hope to reconcile debates on how LLMs can solve complex reasoning problems yet fail at simple tasks when made longer, and highlight the massive benefits of scaling model size and sequential test-time compute for long-horizon tasks.

That is “data bending” (borrowed from “circuit bending”; e.g. opening a toy that makes sound and using ‘a moist finger’ probing the pcb for changes in sound). Glitching is the intentional act of introducing errors in hardware or software, to expose the inner workings (in the case of Glitch art, this was the original aim, to expose ‘the ghost in the machine’). Rosa Menkman wrote extensively about Glitch Art here: https://beyondresolution.info/Glitch-Studies-Manifesto
