You mention the "uncharged case", but ordinary matter is not mathematically neutral.

YOUR CODE assumes that it is, when it passes "q": 0 for four of the six objects.

For the other two, it passes "q": 1. Let's look at what it does then:

L_src is much much smaller than Le, by roughly a factor of (mass / mPL)^2

The calculation of lambda_a uses the electron mass even when calculating for a proton

For the given objects, metric_factor is negligible.

ai_unified = c^2 * (alpha * hbar / (me_kg * c)) / r^2 = alpha * (hbar * c) / (me_kg * r^2)

but alpha = k*e^2 / (hbar * c)

so ai_unified = k * e^2 / (me_kg * r^2) + small correction of O((mass / mPL)^2)

That's exactly the formula used for acc_coloumb in the code. Also interesting to note the "Coulomb acceleration" for a proton is calculated by dividing the electric force by the mass of the ELECTRON somehow.

As for "Phase 2"? The program's output doesn't even agree with the implementation about the formula being used.

I hope the students can choose to use their own wifi at home if they have it, much better service for them. Depending on how it's setup, the cellular contract may be not be that crippling. When enterprises buy thousands of services they pool data across the SIM's and get quite reasonable rates for what is used, be it a fleet of IOT devices with low usage or laptops with some high usage. If you are just buying one service, you are really at a disadvantage compared to enterprise deals.
Show HN: Eze – AI startup roadmap co‑pilot (Day 3 update)
by foolmarshal | 2025-12-23 02:47:11+00:00
Hi HN,

Day 3 of building eze, an AI co‑pilot that turns raw startup ideas into execution roadmaps.

What’s happened since the last update

- Early trust: More than 10 people have joined the waitlist for early access and early‑bird benefits. Still tiny, but it’s enough signal that the problem and framing resonate.

- Canvas revamp: Rebuilt the roadmap canvas from basic boxes-and-arrows into a more interactive workspace. Stages are visually separated, nodes are cleaner, and it’s much easier to see your current position in the journey.

- Chat UX upgrade: Improved the chat interface so it feels like a focused founder workspace—clearer prompts, better typography and spacing, and less “generic chat window” energy.

- Pain validated by another builder: A fellow Indie Hacker described their current setup as a pile of long ChatGPT threads + bookmarks where CTRL‑F barely helps because everything is split across many conversations. They want “one product to bring order to all the steps with an easy way to search and navigate.” That’s exactly the chaos eze is meant to clean up.

- Towards credible guidance, not fluff: I’ve started collecting authorized, high‑signal sources on how experienced founders actually build companies—YouTube transcripts, articles, blogs, and summaries/notes from classic startup books. The idea is to ground eze’s roadmaps and suggestions in real founder behaviour and robust frameworks, instead of generic, feel‑good LLM advice.

The north star stays the same: remove one big variable in the founder journey — “what should I do next, and in what order?” — so more people can move from idea to launch with a realistic, personalized plan.

If you’d like to follow along or get early access once v1 is ready:

Feedback, skepticism, and “this will fail unless you solve X” comments are very welcome.

> Economic central planning is a fool's errand.

crazy, because the two biggest cases of economic central planning are the USSR which grew faster than any civilization ever (a literacy rate of 30% to 100% in 60 years) and China who is currently making the United States world power look like a toddler.

There's clearly something to central planning, it's still up in the air if you can totally plan an economy centrally. I tend to agree with Chibber.

People at ALL wage levels put themselves into wage slavery by setting up their finances in a way where they have very little buffer. Mortgage, car payments, savings levels, and all sorts of things combine into being even briefly unemployed is a terrific burden.

In that state, you can't say no, you can't stand up for yourself or anyone else, you can't make choices because choices have significant life effects. You don't have to have a $10MM trust fund to escape this. You just have to live far enough under your means that you have the savings and spending profile that allows you "fuck you" privileges.

Everybody living so close to broke all the time makes everything more expensive, particularly the competitive things like housing.

Not gonna lie, I’ve driven thousands of cars professionally including almost every Tesla and the entry/exit is always a nightmare. As a technician or driver, I always had a moment of ennui when I saw the make Tesla roll in.

Maybe I’m a moron, additionally I’m sure you get used to it as an owner of that specific thing, but universally my colleagues opined: “Oh, fuck teslas.”

They are cars that drive though, not to yuck your yum.

> Global human populations are in decline; fossil fuel use will decline along with us.

That doesn't follow as the per capita consumption trends are still steadily increasing ... large numbers of people across the planet barely using any resources is far less of a problem than substantially fewer people all consuming like central north americans (which is increasingly the aspiration goal).

> doesn’t that alone adequately address the climate change concerns?

No.

The amount of CO2 in the atmosphere is already problematic and will remain there for hundreds of years (unless removed).

The amount added each year by human activity is still increasing .. it needs to stop increasing, and to fall substantiatly, and probably something done about extraction or other mitigation.

> Does it really make sense to overhaul the global energy generation infrastructure

Yes .. and on the plus side that's already happening thanks to China, the EU, past US administrations, etc. THe current US administration isn't helping .. they appear to be doing very much the opposite of helping given the cosy relationship with existing fossil fuel companies.

No, it wasn't. Those are mostly available in PLCC and DIP packages and even if you can get the SOIC/TSSOP versions they still cost $1.20 each at 10k volume. That's flat-out unacceptable for 99% of the things I do. The entire rest of the board I was talking about was $4.60. Processor included. $1.20 is not going to fly.

Yes, IP usage is awkward and tricky. You can use the GUI to make the initial .xci file or .tcl file, but when you build a project, you need to use the same version of Vivado that the IP core was originally created in. Xilinx have improved that a little with 'write_ip_tcl' and 'write_bd_tcl' now having flags that let you ignore the version (or minor version). I've not had time to try those yet.

How about we just give their entire families Internet access for free?

Fios js something like $75/mo for gigabit Ethernet (inclusive of a WiFi router, etc) and there are smaller gigabit providers that will give you service for under $50. And with bulk contracts I’m sure the govt could get a better price than even that.

If the govt can negotiate a rate of about $25/mo it could provide all 800k students homes high quality internet.

But only about 115k are estimated to have insufficient internet access so at $50/month, you can provide (let’s round up to 150k students) all their families internet access for $90mm as opposed to the $200mm they’re currently paying.

Nevermind. The article states the city has gotten Spectrum to agree to $15/mo service. So providing every student’s family free internet service would cost the city $160mm. You would still save well over 20% before considering the hardware cost savings by not having to buy LTE.

from the linked drug trial article, https://www.nejm.org/doi/full/10.1056/NEJMoa2500969:

Gastrointestinal adverse events were more common with oral semaglutide than with placebo (74.0% vs. 42.2%).

That placebo value seems high (42.2%), given it's just a placebo (sugar pill?).

Question, have you been an immigrant? Do you know any immigrants?

When you immigrate into a country, all of a sudden all of your reflexes are wrong. Some are obviously wrong. Some are more subtle. It is overwhelming, and too much.

While in retrospect it is easy to say that they should prioritize some things over others, in practice they tend to learn from experience after people respond badly, and those who are a little more used to the culture explain why they are wrong. And the experience of being told that they are wrong all of the time will make many hold on to some of their old habits extremely strongly.

Don't criticize how slowly immigrants adapt to a new country, until you've been an immigrant in a foreign culture.

I agree and disagree. In my day job as an AI engineer I rarely if ever need to use any “classic” deep learning to get things done. However, I’m a firm believer that understanding the internals of a LLM can set you apart as an gen AI engineer, if you’re interested in becoming the top 1% in your field. There can and will be situations where your intuition about the constraints of your model is superior compared to peers who consider the LLM a black box. I had this advice given directly to me years ago, in person, by Clem Delangue of Hugging Face - I took it seriously and really doubled down on understanding the guts of LLMs. I think it’s served me well.

I’d give similar advice to any coding bootcamp grad: yes you can get far by just knowing python and React, but to reach the absolute peak of your potential and join the ranks of the very best in the world in your field, you’ll eventually want to dive deep into computer architecture and lower level languages. Knowing these deeply will help you apply your higher level code more effectively than your coding bootcamp classmates over the course of a career.

It's mostly the whole "two binaries" problem.

Oh look, the factory screwed up and isn't flashing the MCU this week! Does the board survive?

Oh look, the factory screwed up and isn't flashing the PLD this week! Does the board survive?

Oh look, the factory... wait, what is the factory doing and why are they putting that sticker on that....

You get the idea. Yes, yes, it is all solvable. I have never claimed it isn't. I am just claiming it is a giant pain in the ass and limits use of these things. I will bend over backwards to keep boards at one binary that needs to be loaded.

You can look at who the "Stratum 2" servers are, in the NTP.org pool and otherwise. Those are servers who sync from Stratum 1, like NIST.

Anyone can join the NTP.org pool so it's hard to make blanket statements about it. I believe there's some monitoring of servers in the pool but I don't know the details.

For example, Ubuntu systems point to their Stratum 2 timeservers by default, and I'd have to imagine that NIST is probably one of their upstreams.

An NTP server usually has multiple upstream sources and can steer its clock to minimize the error across multiple servers, as well as detecting misbehaving servers and reject them ("Falseticker"). Different NTP server implementations might do this a bit differently.

> The absence of guard rails is a good thing

It's really not. I have no axe to grind with Elon, but X and it's reputation for "oops we made a mistake" critical failures is a no-go. I don't feel safe signing up to try whatever their free model when their public image is nonstop obvious mistakes. There is no world where I'm bringing those models to work, and explaining to HR why my web traffic included a Mechahitler response (or worse).

Anthropic and OpenAI are Silicon Valley circuses in a relative sense, but they take this stuff seriously and make genuine advancements. XAI could disappear tomorrow and the human race would not lose any irreplaceable research. It's a dedicated fart-huffing division on the best of days, I hope you're not personally invested in their success.

But why would it be amazing? The alternative right now is that you do it in software and just dedicate a couple of cores to the task (or even just put in a separate $2 chip to run the decoder).

Like, I get the aesthetic appeal, and I accept that there is a small subset of uses where an FPGA really makes a difference. But in the general case, it's a bit like getting upset at people for using an MCU when a 555 timer would do. Sure, except doing it the "right" way is actually slower, more expensive, and less flexible, so why bother?

No, you’ve got it wrong. That kind of situation doesn’t exist. They only said that, in areas heavily visited by Chinese tourists, you can’t use loudspeakers to shout racist things at tourists within a certain radius of tourist sites.
And why would you think you can’t insult the U.S. or China, or any other country? Even 10 minutes ago, I opened my window and yelled “F* C*,” and nothing happened.

> If the algorithm "working as intended" consistently downranks stories that cast a bad light on YCombinator

We manually intervene to reduce or remove the penalties that downrank YC-related stories. Thus, stories like this one get more front page exposure and discussion than they would if they were not YC-related. And anyone can audit this via /active, HNRankings and any other tools they may want to build by pulling data from the API.

> the sorts of people y'all mingle with, or the tech industry in general

That phrase reflects an assumption that YC is synonymous with the tech industry and that everyone at YC and in the tech industry “mingles” and agrees with one another. That’s far from true. Even among the YC partners there are differences in opinion about these things, and there have been huge public disputes in recent years between prominent YC-aligned figures and other major tech industry identities.

It’s natural that people come to HN to discuss and scrutinize the activities of the tech industry, given that we’re a major public discussion forum focused on the tech industry. We accept that and make allowances for it. It doesn’t mean we need to apply the same lower-moderation philosophy to every tech industry controversy that we do when YC is a part of the story.

The CNN article about the oral version of Wegovy has more details, https://www.cnn.com/2025/12/22/health/wegovy-pill-glp1-weigh...

... Overall, 7% of participants in the Wegovy pill trial stopped treatment because of side effects, versus 6% on placebo. ...

One difference between the medicines is that the Wegovy pill must be taken on an empty stomach with a small amount of water, and patients are directed not to eat, drink or take other medicines for 30 minutes after taking it.

Lilly touts that, in clinical trials, orforglipron (Ed.note Lilly's similar version to Wegovy) was taken once a day at any time, without restrictions on food or water.

While the price of $149 for the starting dose is lower than what the companies currently offer for the injectable drugs, that price is only for the initial, lowest dose. These medicines are designed to start at a low dose and have patients gradually ramp up over time, to manage side effects; the Wegovy pill will come in doses of 1.5 milligrams, 4 milligrams, 9 milligrams and the expected longer-term dose of 25 milligrams, Brett said.

“The lowest dose is almost never the dose that people wind up being on,” said Korner. “That’s just sort of like a loading dose, to let your body get used to it.”

Lilly, which will also offer the $149 starting price under the Trump agreement, says additional doses of orforglipron will cost up to $399 if patients are paying cash.

An example of why a basic understanding is helpful:

A common sentiment on HN is that LLMs generate too many comments in code.

But comment spam is going to help code quality, due to the way causal transformers and positional encoding works. The model has learned to dump locally-specific reasoning tokens where they're needed, in a tightly scoped cluster that can be attended to easily, and forgetting about just as easily later on. It's like a disposable scratchpad to reduce the errors in the code it's about to write.

The solution to comment spam is textual/AST post-processing of generated code, rather than prompting the LLM to handicap itself by not generating as much comments.

You should check out Eric Adams in more detail. The guy - and his team - ranges from ridiculous to nuts to outright corrupt. A few excerpts:

>> Equally memorable, perhaps, were the strange subplots along the way: his hatred of rats and fear of ghosts; the mysteries about his home, his diet, his childhood; and his endless supply of catchphrases, gestures and head-scratching stories that could instantly transform a mundane bureaucratic event into a widely shared meme.

>> Then, on Sept. 26, 2024, federal prosecutors brought fraud and bribery charges against Adams, accusing him of allowing Turkish officials and other businesspeople to buy his influence with illegal campaign contributions and steep discounts on overseas trips.

>> Investigators also seized phones from the mayor's police commissioner, schools chancellor and multiple deputy mayors. Each denied wrongdoing, but a mass exodus of leadership followed, along with questions about the mayor’s ability to govern.

>> ...Weeks after Trump took office, the Justice Department dismissed the corruption case, writing in a two-page memo that it had interfered with Adams’ ability to help with the president’s immigration agenda.

Verification and traceability is one reason: it's all very well to claim you're with-in ±x seconds, but your logs may have to say how close you are to the 'legal reality' that is the official time of NIST.

NIST may also send out time via 'private fibre' for certain purposes:

I was clear that the junior should be learning and experimenting. That's different from saying yes to everything and grinding it out. The juniors in my group, for example, are the ones leading the LLM charge and learning the new tooling ahead of management's awareness of them, so almost by definition they're not just filling their time taking orders from management. That's exactly how they should be spending their excess capacity.

The street parking deal is chump change. Government’s routinely pay government employees with underfunded defined benefit pensions and retiree healthcare for a penny today. Especially Chicago and Illinois (multiple standard deviations above the norm).

I’m pretty sure they sold the street parking because of the underfunded obligations to previous employees.

Ask HN: LLC or Sole Proprietorship
by dandeto | 2025-12-23 03:04:38+00:00
I am wondering if anyone has advice on forming an LLC or operating my "side hustle" as a sole proprietorship. I will be launching a website in 2026, and I don't know if I will make $20 a year or $2,000, but I don't expect it to be much more than covering operating costs. The pricing model is free with an upgrade to premium for extra features. No ads.

What I've been reading online talks a lot about liability, insurance, and other issues that I do not foresee being relevant to running a website, but it sounds like an LLC mitigates those issues. It will cost me a few hundred dollars and quite a bit of time to set up an LLC... I could always start as a sole proprietor and then make the switch if I deem it necessary, so that's the option I'm leaning most towards.

I know plenty of folks on here have hobbies and small businesses or websites they try to monetize, so maybe you have an idea I haven't considered?

The people who don't agree with you are largely reasonable, as you likely are, and are no more infectees of a "mind virus" for holding their opinions than you are for holding yours. There's no need to denigrate them, or misrepresent their views to try to make your point. Indeed, many of them arrived at their opinion after seeing what happens when people push for not-enough regulation: Once bitten, twice shy.
