Gigabit is the slowest reasonable fiber speed. Even 10-gigabit is now very cheap to the point that some gigabit equipment is just 10-gigabit equipment operating at a low speed. They could artificially throttle you to even less, if it made business sense.

It's not a committed rate. Your individual line is a gigabit, but the upstream from your whole block is 10 gigabit so you can't all use it at once. Your guaranteed rate is probably have more like 20-50 Mbps, if that's what's confusing you. But it's extremely rare that everyone tries to use their gigabit all at once.

If it's a Passive Optical Network, you might be sharing a gigabit download with your block - you all share the same fiber - and you get substantially less than a gigabit upload due to the need for timeslotting. Gigabit PON is obsolete though, now you'd get at least 10G PON.

tip for the flu or cold: because they (viruses) get into your sinuses, and start to multiply there, not in the mouth or stomach, then would be good to put something in the sinuses to kill them. This needs to be done at the first sneeze! when there aren't yet billions of them. netipot, with cleaned water + salt is the way used for thousands of years. What is extra is to put pea size amount of cold pressed/virgin coconut oil in there (when water about 30c degrees, but not hotter) and flush with it. antiviral and antibacterial, gives nice coating also to sensitive skin inside sinuses. you'll skip the whole perioid of getting sick. works. trust me

Why? Why presume that? These employees got screwed. They were left with a shell of a company that got bought for pennies on the dollar while their executives and executive pets all got massive payouts moving to Google. It was a total dick move and the result will be a flight from startups because who wants to bust their asses for an executive team that will leave them behind when the payout arrives.

I think one of the answers here may be nVidia related. CP2077 is one of those games with a ton of "optimized for/by nVidia" magic with the nVidia driver injecting a lot of its own GPU/CPU code adjustments into the game. Given the Linux nVidia driver is a fraction of the size of the Windows driver I've long assumed there's a lot less "optimized" code being sent to the Linux side than the Windows side. It's interesting to wonder if it is because Linux needs it less or if Windows is still the flagship for "most features"/"best graphics" for nVidia so DirectX gets all the attention.

I don't see this. The ai software engineer that succeeds, maybe it's because of a mixture of very complicated architecture derived from novel research etc. You can't replicate that with just hiring more human engineers, it takes time and effort and elite hiring. Plus enterprise support etc.

Devin etc will give you let's say 10x more engineering power, but not necessarily elite one.

Yep. The reality is folks building these types of companies are trying to get acquired as quickly as possible before the house of cards fall. This has led to a huge speculative rush of acquisitions to avoid FOMO later.

The technology is nowhere close to what they're hoping for and incremental progress isn't getting us there.

If we get true AGI agents, anyone can also build a multi-billion dollar tech companies on the cheap.

My 2 cents: I prefer to emphasize quality over scope, meaning relentlessly adopt habits that reduce bugs to rare events. Don't take on extra scope unless you can deliver a working system, wait until next iteration.

Reason (my context: small team(s) but in a somewhat complex and integrated environment):

Many times, bugs in production cost the company (IT and business areas) much much more to identify/correct/resolve then making sure the stuff works in the first place.

Incorrect transactions flowing between different systems and different areas of the business and possibly out to customers and other external partners are time consuming to correct, or require costly manual labor to work around.

> As introduced in the previous chapters, all identifers are hashed, thus we can also hash the known keywords at startup and make comparing them very fast.

One trick that postgres uses [1][2] is perfect hashing [3]. Since you know in advance what your keywords are, you can design such hashing functions that for each w(i) in list of i keywords W, h(w(i)) = i. It essentially means no collisions and it's O(i) for the memory requirement.

“There are no known chemical processes for the production of either ammonia or phosphine ..."

After reading this, I was curious how ammonia can be produced in industrial quantities on Earth. The process does appear to be a chemical process:

One famous example is the Haber-Bosch nitrogen-fixation reaction, which uses a simple iron catalyst to make ammonia and other nitrogen-containing compounds from nitrogen and hydrogen

No. Graders having multiple roles is actually the implementation detail, since they're people, and they can't spend all day grading work. Scanning machines don't really grade work either, but I am happy to rely on them for checking an answer matches a scheme verbatim. I'm not sure why you mention scanners answering tests either, since my original comment doesn't imply that.

There is no evidence that an LLM can reliably evaluate the semantic content of a sentence, even in cases where we all agree that the semantic content exists. The thread we are participating in demonstrates a particularly egregious failure, but there is no good reason to think that more subtle failures might not exist if we happen to patch this one. Even if they were reliable, you can't evaluate a system with itself - that is basic science.

I wonder how this works/worked from an evolutionary perspective. Are vengeful people effective enforcers of tribal norms and customs? It would be a good deterrent to not cross someone if you knew they would destroy themselves to destroy you.

Still, one doesn't have to look far to find talking heads who will happily tell you that some group of people has slighted you and that you need to respond (by voting for [X]). So even if vengefulness is helpful, and even if forgiveness is the answer for unhelpful vengefulness, is there any way to keep it from being hijacked at scale?

Is it religion?

What happens inside cannot be known.

As I understand it, black holes are defined by three quantities: mass, spin, and charge.

I'm assuming that these quantities will be additive post-merger.

Edit: "The black holes appear to be spinning very rapidly—near the limit allowed by Einstein's theory of general relativity."

Perhaps the additive spin becomes asymptotic. Alternately, the gravitational waves might have departed with the energy of the excess spin.

If you have fifty bright and highly competent people, I'm skeptical that adding fifty idiots is going to make much of a difference. Most idiots will accept meritocratic authority if they can be convinced that their needs are taken into account (which they should). Some will obstruct, but probably not enough to significantly derail anything, and the good-faith idiots will bring information and perspectives that wouldn't be considered if they weren't there, so they aren't exactly useless.

In fact, I would argue that idiots in elected bodies are a lot more likely to do damage than random idiots, because they are more likely to be narcissists, and being elected boosts their sense of self-worth. And of course, the most damage is often caused by the most intelligent of them, because the main problem is acting in bad faith, not a lack of wits.
Show HN: StartupList EU – A public directory of European startups
by umbertotancorre | 2025-07-14 20:24:36+00:00
I’m from Europe, and when I spent a summer at Stanford, I saw how different the startup ecosystem is in the US. Everything there feels connected. In Europe, it’s scattered. Hard to discover early-stage startups unless you’re in the right city or network.

So I built StartupList EU, a public directory where anyone can list or browse European startups.

The goals is to contribute to the EU startup ecosystem more accessible and transparent for founders, investors and operators.

What it does: - Founders can submit their startup for free - Each profile includes data like team size, category, funding, revenues, location, founders and more - You can search by country, industry, name, team size, country and business model - It works across the whole EU, not just big hubs like Berlin or Paris

Right now there are 34 startups listed. More are coming in daily. I’m working on better filters, API access, and a weekly newsletter.

Would love your feedback: - What data would be most useful to you? - What would make this genuinely helpful for founders, investors, or researchers? - If you are from US, what's your take about EU startup ecosystem?

The original statement which I replied to was an absolute position. These examples invalidate it.

Also note that both of your comments show that people in a position to choose, are choosing single sex schools for their daughters and getting better outcomes on average.

Lastly, while the article mentions some caveats around selective state schools, the other side of that is the UK has many single sex comprehensive schools. We should not ascribe too much weight to the caveat.

There is a meta-analysis from 2023:

> Recent studies have shown that short-term exposure to high levels of indoor carbon dioxide (CO2) could negatively affect human cognitive performance, but the results are still controversial. In this study, a systematic review and meta-analysis of fifteen eligible studies was performed to quantify the effects of short-term CO2 exposure on cognitive task performance. The control CO2 levels used for comparison were below 1000 ppm, while the exposure concentrations were divided into three groups: 1000–1500 ppm, 1500–3000 ppm, and 3000–5000 ppm. The results indicated that CO2 exposure below 5000 ppm impacted human cognitive performance, with complex cognitive tasks being more significantly affected than simple tasks. The complex task performance declined significantly when exposed to additional CO2 concentrations of 1000–1500 ppm and 1500–3000 ppm, with pooled standardized mean differences (SMDs) (95% CI) of −2.044 (−2.620, −1.467) and −0.860 (−1.380, −0.340), respectively.

> People don't grasp how easy it is to build data models like this even without privileged first-party data access.

Correct. But this is about them using first party data access, and often times this data is stolen; then utilized by any body/any thing - in this case, CBP and ICE to do unreasonable searches and building of data models which are often, but in these cases: Probably used against both citizens and non-citizens.

It's absolutely amazing that these data models can be built, Meta and Anthropic pirated entire libraries of books to build their AI models at zero consequence.

The point I'm making is, why are the people the one that have to be exploited in the building of these models, and then the sale of them?

I've begun to think some bubbles are good for the economy overall. In the dotcom days anyone with an idea and a domain name could get funding. I myself worked for a company that nabbed 7x more funding than needed but still failed due to poor leadership. I had reservations about the founder but thought I could help drive things, but he was even more absent than I ever anticipated.

A lot of VCs and PEs lost a lot of money during the crash. This means a lot of capital was spent in the economy, generating a lot of good activity, and the companies that failed then also put a lot more capital back into the economy through bankruptcies. Other businesses can pick up talent, IP, and assets for cheap, and everyone can learn from the failures. While losing that money isn't great for VCs, what they got was a very valuable education to be better stewards of their investments, and pick better companies. The next rounds of companies have to hit metrics, milestones, have to prove their value, etc.

Never waste a perfectly good crisis: learn if nothing else.

> I guess I'm just a bit surprised that no distro has taken up the mantle of providing these things; it seems to me it should be possible to build a stable ABI and HAL on top of the existing Linux kernel

Doesn't that distro already exist and it is called WINE?

As funny as it is to pattern the stable ABI and HAL so directly after Win32, it's also a hardened, well battle tested one. Rather than needing to design something from whole cloth and then get user and driver code buy in for it, why not just use an ABI and HAL with a lot of existing code? WINE is a funny answer, but it is a respectable one. (I appreciate the "overnight success 20 years in the making" joke above, too, about it.)

>Click-bait headline makes you think otherwise, but this is just standard hospitality stuff.

It's so standard that it's actually part of the training at that universally-known 0 michelin star italian travesty, the olive garden. When I worked there we called it "surprise and delight" because I'm sure if we called it collecting the dots we had to pay Danny Meyer. We were taught to observe our guests and even ask some questions in order to gather intel and then confer w the MoD in order to brainstorm ways to make the guest's visit special. We didn't have the resources to do things like the Pequod's scene from The Bear but what we could do we took great pride in doing. Our store was in the area where a soup called stellini is available. It's basically a chicken noodle soup w little pasta stars, spinach and meatballs, derived from a Pittsburgh-area specialty called wedding soup. Idk who in an olive garden in another state let slip that their large party was from Pittsburgh but the GM from that store called us and we overnighted a bunch of stellini to that restaurant (at corporate's expense, of course) just so they could have the same experience at this other store that they do at home.

> so they can trilaterate or triangulate strike locations

I don't think that's feasible. These sensors work by detecting radio waves which propagate near the speed of light. Even if you had two sensors separated by 1 km, they'd both receive the radio signal within ~3 µs of each other. I don't think the sensors guarantee detection time to that level of precision, nor that it's feasible to keep clocks sufficiently synchronized that you can timestamp events at a sub-microsecond level.

The problem is the bullet point features that Microsoft is adding to Windows (AI, ads, Xbox bar, etc.). The fastest line of code possible is the line of code that doesn't exist (look, this technically isn't true when considering data structures, but it's a good baseline).

Microsoft would have to exercise discipline with Windows features, which is never going to happen: the very people pushing the garbage are using Macs and don't have to suffer it.

Radio Shack rebadged lots of products from outside sources, with the CoCo I/II being mostly a Motorala design for the AgVision terminal. The CoCo 3 is notable because so many of the improvements were driven by in-house processes. I wondered if maybe some of the people who worked on the CoCo 3's improved graphics were behind the Tandy Graphics used by the 1000 line but nope, turns out they went back to what worked for them and copied IBM's modes from the PCjr.

If you still have an interest in the CoCo 3, the port of Attack of the PETSCII Robots is coming along.

They become a more massive one. The volume of a black hole (assuming you're measuring at the event horizon) is determined only by its mass, so the final density is the same as you'd get for any other black hole of that mass regardless of how it came to be.

I don't know how to address the "consume" question. If you were pulling on a piece of fabric and two tears in it grew until they met each other to become one tear... would you say that the larger one consumed the smaller?

Yeah, only those evolved a lot from the initial products everyone hyped and products people hyped in 2000 are extinct or free. And I still don't understand where Facebook makes money. :)

Regarding LLMs there are two concerns - current products don't have any killer feature to lock in customers, so people can easily jump ship. And diminishing returns, if there won't be a clear progress with models, then free/small, maybe even local models will fill most of people needs.

People are speculating that even OAI is burning more money than they make, it's hard to say what will happen if customer churn will increase. Like for example me - I never paid for LLMs specifically, and didn't use them in any major way, but I used free Claude for testing how it works, maybe incorporating in the workflow. I may transitioned to the paid tier in the future. But recently someone noted that Google cloud storage includes "free" Gemini Pro and I've switched to it, because why not, I'm already paying for the storage part. And there was nothing keeping me with Anthropic. Actually that name alone is revolting imo. I wrote this as an example that when monsters like Google or Microsoft or Apple would start bundling their solutions (and advertise them properly, unlike Google), then specialized companies including OAI will feel very very bad, with their insane expenses and investments.
