For most use cases that's true. But for a surprisingly large number of use cases that's not true at all.

I was thinking of using a high-frequency trading example, but here's a case that's a bit more normal: stadium concert audio for a live band. Stadiums are big enough that you need to deal with latency issues for audio, because the back of the venue will get its audio a bit later than the front of the venue (assuming the sound is wired so the board is in the front of the floor and no adjustments are made). That is obviously disconcerting to the audience. Adjustments usually are made to handle this problem.
Apple issues stock at $200/share. Bob buys one share. Apple is now $200 richer, Bob is $200 poorer.

Later, Apple goes up to $300/share. Bob sells his stock to Charlie. Bob is now $100 richer, Charlie is $300 poorer. Total change: zero.

Apple is more valuable and that (probably) means wealth was created, but that increase in wealth comes from Apple doing things, not from the trading.

Non-stock trading creates wealth because different people value things differently. A sandwich is worth less to Subway than it is to me, so total wealth increases when I pay them for a sandwich. But stocks don't really work that way. Unless you're buying a stock to exert control over the company, the only thing you're doing with it is using it to make money money. If you're making money by selling at a higher price later, then that comes from someone else paying that higher price, and it's all zero-sum.

I was responding to "Pension funds, banks, HFT firms can all make money while trading with each other." I readily accept that economic activity is not zero-sum, creates wealth, and that trading stocks can help enable that. But just trading by itself doesn't make money.
Your other comments across the larger topic refute your claimed good intentions. It's not that wild that no one would believe you, when you contradict yourself.
Well, that also democratized publishing. For better or worse. Anyone can have a voice now that can spread without needing access from (human) gatekeepers or mastering arcane incantations. Starting from when there were like 4 TV channels, I think this has generally been a good and lauded direction.
I don't disagree with that at all.

I thought I was pretty clear that I was taking issue with the absolutist ultimatum:

That is an entirely different position than saying we can easily afford it and should.

As a matter of personal preference, hoisted curlies drive me insane.
I really have trouble understanding that map. What does "Active and Passed" mean? I assumed it meant they had passed laws and updates in the works, but those States are excluded from the praise over the "Passed" States. I presume "Historical" means "Failed to pass" and no current activity to get a law passed.
For Llama 3 70B, batch size = 1, each MLP layer roughly takes 1x8192x26872x2 + 1x8192x26872x2 + 1x26872x8192x2 FLOPS ~= 1.31 GFLOPS, instead of ~1 TFLOPS.

Since the number differs by roughly 1024x, maybe you forgot that you just need to work on the last decoded token for MLP, too? Because you don't need hidden state for previous tokens in Attn now.
It doesn’t say much, and to me it reads like an emotional anti-Musk take:

> ignoring the LEO satellite platform’s capacity constraints, high prices, erratic leadership, and problematic environmental impact

I think capacity constraints are nonexistent for most uses, and capacity is increasing all the time. Clearly LEO has enough capacity because there are many other large constellations also launching. The price is not very different than Comcast or whoever, but with much easier installation, better speeds in most areas, and better customer service. The “erratic” leadership has no effect on the problem we’re discussing, and in fact, Musk has done amazing work with SpaceX and Starlink.

On the other hand we’ve already spent tens or hundreds of billions on traditional broadband to neglected areas and got very little for it. We would have been better off giving all those people the money directly so they can pay for satellite Internet.

Myanmar's dictators are far less educated than Trump, and also happen to be extremely superstitious. They also have basically absolute power and can kill or imprison anyone they want without any sort of reason or trial.

Imagine if The Trump Organization (the holding company) had its own army, the generals owned shares in the army's business, and there was no civil society outside of the army. That is Myanmar's situation. I can't understate how tyrannical and corrupt it is.

I unfortunately can't, it was apparently added in 2.1.57, which would be somewhere around 1998~1999. I started working with Linux around 2001~2002, and this association of PDEATHSIG with LinuxThreads has at some point embedded itself into my brain… I can't reconstruct when or why. And I can't seem to find the specific patch that added PDEATHSIG, and can't find a versioned history of LinuxThreads either…

It is not, it is actually closer to an insertion sort.

The interesting part is that it often comes up when the one writing the algorithm doesn't know what he is doing, and yet, it works. It may look like a BubbleSort because it is a common wrong implementation of BubbleSort.

The requirements will be modified to include a larger number of sites whenever the government may find this to be convenient. The MAU will limit will be reduced, and/or the scope of "illegal/harmful content" will be expanded.
Surely both the government and rich people can fund research. One doesn't preclude the other.
I like integrant, but I feel like a lot of the examples I see use it for each web endpoint, which seems like a massive amount of overkill to me. I tend to use it just for the router, but it sometimes feels like I'm not using the library to its full potential with that.

This may be a shock to many HN readers, but MongoDB's revenue has been growing quite fast in the last few years (from 400M in 2020 to 1.7B in 2024). They've been pushing Atlas pretty hard in the Enterprise world. Have no experience with it myself, but I've heard some decently positive things about it (ease of set up and maintenance, reliability).

In particular it's depressing that the map near the top of the article shows that for a majority of states, the introduction of the bill is "historical", as in neither passed, active or current, but (IIUC) it was floated in some prior legislative session, but it's not even under consideration in the present session.

Around 10 years ago I found a JIT bug in a JDK from a big Java vendor. A new version of a web application server had been applied. The production application crashed after around 30 minutes of running, almost simultaneously on both production sites. It was an internal checksum calculation in the application that failed - an obscure error never seen before. The upgrade was rolled back immediately. I was assigned to the case and of course didn't suspect a JIT error. But within a week of investigation I started suspecting it must be (but I didn't dare tell anyone!) and I eventually managed to show this and reproduce it consistently. The vendor confirmed and made a temporary workaround via switches that disabled some new optimizations. Later a real fix was shipped.

I've also found 3-4 JavaScript JIT compiler errors in major browsers, all confirmed. I was a developer on what was for its time a quite complicated JavaScript solution, so we tended to encounter obscure JavaScript errors before others.
and have they built anything yet?

You don't hear the big AI providers talk about embeddings much, but I have to believe in the long run that companies building SOTA foundational LLMs are going to ultimately have the best embedding models.

BubbleSort keeps going until no more swaps happen, this algorithm specifies up front which items to compare.

I actually think it's pretty cool, it happens occasionally that I just need a quick and dirty sort and this is easier to get right.
Apple's incentives have definitely aligned with replacing Nvidia entirely ever since they ceased diplomatic relations. But Nvidia also knows this, which is why they invest heavily in things Apple will never do. They write the official Linux drivers Apple wouldn't get caught dead supporting. They give users and integrators freedom to choose their OS, software and library stacks to better suit their application. They sell individual GPUs and unlocked edge compute hardware with no distribution terms or $99/year "developer license" bullshit. Nvidia is a hardware company in places where Apple tries shipping services instead.

Then there's also the software issues. Nvidia has invested in GPU-based compute nonstop for the past 10+ years. Apple invested in Nvidia, then invested in OpenCL after abandoning Nvidia, then abandoned OpenCL for Metal compute which would eventually become the proprietary Accelerate framework. Nvidia's eggs are all organized in one, valuable basket. Apple's investments are spread out all over the place, with much of the time and money going into projects that don't even exist anymore.

Apple has the TSMC advantage, but that's just about it. Their GPU designs aren't comparably efficient or compute-oriented to what Nvidia ships today. Additionally, Nvidia will continue investing in places that Apple principally refuses to support. Unless a serious tide change occurs at Apple, they aren't going to get a fair competition with Nvidia.
FTTH infrastructure is very low maintenance once built, its mostly passive fiber optic cables that don't degrade. The electronics on either end last a long time too.

The issue with FTTH is the build can be very expensive, you need to either work with an existing utility or dig trenches through an entire neighborhood, and each end user install is a mini construction project.

Thats why community FTTH makes a lot of sense, a small team does that negotiation with the utility, and uses that to be build a business case.

My thoughts on the matter may have evolved over time while interacting with other people in the thread. While I do still believe it could have been an attempt at blackmail, I think it most likely was not, even though the researcher clearly must have downloaded the entire database ahead of time based on the chronology presented. In that case, I can see how I have apparently contradicted myself. But I can assure you, I am not acting in bad faith.

I understand the criticisms, but in my experience, MongoDB has come a long way. Many of the earlier issues people mention have been addressed.

Government's ability to publicly fund research is directly related to how much it can collect in taxes.

With wealth being hoarded by individuals at unprecedented rates and taxes lower than they've been at almost any time in the country's history, there has certainly been a shift away from public research toward private research.
Maybe they're excluded because they've already been praised, and they're focused on the new states joining in? I assume "active and passed" means that they not only passed the laws, but they are currently in effect. A law being passed doesn't necessarily put it into immediate effect.

Without those years spent working the problem, would he have recognized that hypothesis as a valuable road to go down? And wouldn't the years of verifying it still remain?
