This is not true. Take the NVidia 4090. 128 SMs = 4x128=512 SMSPs. This is the number of warps which can execute independently of each other. In contrast, a warp is a 32-width vector, i.e. 32 "same operations", and up to 512 different batches in parallel. So, it's more like a 512-core 1024-bit vector processor.

That being said, I believe the typical number of warps to saturate an SM is normally around 6 rather than 4, so more like 768 concurrent 32-wide "different" operations to saturate compute. Of course, the issue with that is you get into overhead problems and memory bandwidth issues, both of which are highly difficult to navigate around -- the register file storing all the register of each process is extremely power-hungry (in fact, the most power-hungry part I believe), for example.

A PPU with less vector width (e.g. AVX512) would have proportionally more overhead (possibly more than linearly so in terms of the circuit design). This is without talking about how most programs depend on latency-optimized RAM (rather than bandwidth-optmized GDDR/HBM).
Another way to put it is that those colleagues are 4 teams away and 2 promos ahead before anyone has worked out exactly what went wrong and whose fault it was.
Adding diet cola causes weight gain the same as normal cola?

Where are you getting that info from? The chemistry doesn’t add up.
The hypothesis is easy to test by looking at historical recycling rates. If they track public opinion then it's confirmed, but if there's a sharp increase when bottle bills pass then it's mostly the (predictable) price signaling effect.

I find the doubt that prices work a bit surprising, since generally HN audiences tend to be above average in market literacy otherwise.

I don't know if it's a Windows/Mac thing, click/touch thing, or Apple vs others thing. I do notice that on Chrome/Firefox/Edge on Windows, when you click away from address bar after modifying the URL, it does not revert the value. Actually same on Android.
What kind of command was it?

If I’m doing something more involved, I’ve got a k9s window open in another pane, making sure the command is having the intended effect.

I guess the riskiest commands would be things like deleting persistent volumes. But our storage class doesn’t automatically clean up the disk in the cloud provider, so we could recover from that too.
It's a big chunk of confirmation bias (you don't remember all the times when that doesn't happen) and all sorts of less obvious behavioral correlations, like, if you tend to talk to someone weekly, and it's been a week since the last time, it wouldn't be surprising to have them reaching out to you around the same time you're thinking of them.

I think this also holds up with how ad tracking aims to hoover up all sorts of data to find correlations. There are probably a lot of non-obvious correlations in there, which causes ads to sometimes eerily seem to read minds. These same correlations may cause people to exhibit very similar thoughts without needing to invoke quantum entanglement.
The cost/quality thing doesn't mean they couldn't have maintained a "halo product" line that steered the platform. It could have been like the early 1990s PC market: government with a 'buy domestic' mandate or budget-no-object buyers might have bought a PS/2 Model 80 or Deskpro 386, but the masses, especially overseas, would buy a white-box 386DX made of Taiwanese parts.

There's an interesting contrast: while Japan produced MSX-- a clear example that a multi-vendor standard can be wildly successful-- they missed the idea of a clone ecosystem for their heavier-duty professional machines. Why weren't there vendors cranking out clones of the PC-98, FM Towns, or X68000? Did they require more propriatery special sauce than an IBM 5150, or was there a cultural/market difficulty that would have caused them to flop on the market?

OTOH, perhaps part of the problem was that the features Japan needed had poor cost/benefit ratios outside of the CJK market: you either have to make the enhanced video stuff optional, reducing platform standardization, or charge people for a feature they don't see as immediately beneficial.
This (the comment in the example link) is really an amazing sharing of learned information!
Yes, it could, but my belief is that as long as the company isn't about to go out of business, it doesn't matter because the competitive advantage within our bracket is irrelevant when compared to the top of the entire league. In order to actually increase the size and profitability of the company to a hugely notable degree, they'd need a hell of a lot more changes than just WFH->WFO.
Today's Great Pyramid is much different than what the Great Pyramid looked like when it was first built, according to the TV programs I've seen. There used to be an outer layer of white limestone on the pyramid.

see https://www.livescience.com/how-egyptian-pyramids-originally...

I'd be more impressed if Egypt restored the Great Pyramid to something close to how it looked when first built.
Most Wordpress sites can go static (like using WP2Static), so the HTML online is always fast.
I will say that stored procs are specifically messy, and we did not have many of those. They had a tendency to really explode the change file. With DDL, you can fix a table column in isolation. Fixing a typo in a 100 line stored proc is another 100 lines. And we certainly didn't have multiple people working on the same proc at the same time.

We had no real need to address that aspect, and I would do something more formal with those if I had to, such as having a separate file with the store proc, and simply a note that it has changed in the change file. I mean, that's a bit of a trick.
Historically, it is minuscule. It wasn’t too long ago that waging a war for too long would bankrupt most countries, but the US has been waging wars for almost the entire time it’s existed, and it’s managed to build the worlds largest economy while doing it. But you’re suggesting we debate whether defence spending should be 3 percent rather than 4 of GDP. If all of our allies properly contributed to our defence, it could probably be 2 or less. I’m not a big supporter of government spending, but the effectiveness of our defence spending for its tiny relative cost is remarkable compared to literally any other period in history.
> private equity will use open source, maximize profits from the Labour open source volunteers have done, and minimize costs wherever they can

Still a bizarre hill to die on. Were contributors misled about the license that allows a private or public company or a nonprofit org to use the software for profit?

Did Matt Mullenweg delude himself into thinking that only people who share his ethos about content would use the software?

Did noone learn anything from the lamentations that started with Berkley and ATT, continued with Redhat and most recently with Elastic-Amazon and Hashicorp-itself?

My impression is that Mullenweg is a thoughtful person, so maybe I'm missing something.
In that era of gaming, just waiting a few years meant sequels were better just due to extra computing power, so yes, Fable II was better in most ways (although I'd argue the main story was worse). It was still trying to define many gameplay mechanics that are just standard fare for western made action RPGs. One can play Fable and Morrowind, then look at Skyrim, and see how it owes about as much to Fable as to Morrowind.

It's harder now, because so much of the genre seems to have frozen. The graphics are many times more realistic, and animation blending has come a long way. But ultimately making changes is now so much more expensive, that significant novelty is difficult to find in games that also push what could be done, the way it was back when the first two Fable games could try to push ahead in all direction at once
>That's your opinion. It's wrong.

Unless you are actively working on this issue I will consider your opinion no more valid than mine. There may be papers about the issue but that does not in itself prove how bad the issue is. I don't have time to find and read "a list of papers as long as an arm" anyway and I would bet good money that you didn't read them either.

>There are proposed work arounds which have been ignored.

Do you know if there is a legitimate technical reason why those might not have been implemented? Will any of those billions going to radio astronomy go toward reengineering the technical marvel that is Starlink? Doesn't the FCC inspect and approve all of our privately-owned satellites?

I'm not an astronomer or a rocket scientist but it seems to me that emitting continuous "noise" aka a radio signal is fundamental to the operation of satellite internet on such a scale. You don't have to respond with another pompous "Nah uh" because I don't care anymore.
Feature phone? What year is this where the only options are a $1200 iPhone or a "feature phone"?

A person can walk into a Best Buy today and buy a carrier-agnostic, factory-unlocked Android phone -- new, in a retail box, with a warranty -- for less than $100. No strings, no contracts, no weird stuff. It's just an item that they have for sale in their store.

(Or, FFS: The last Android phone I bought new was $64.00, including tax and overnight delivery. It came with a 60-day carrier lock, but my carrier is cheap.)
They really aren't expensive anymore in the US if you shop around. You can get unlimited data, talk, text for $18/mo per month from US mobile, and you can even choose which network to use Verizon, tmobile, or ATT. US mobile has a new feature that lets you switch the carrier network for $2 per switch.
Are they actually discounted? Where I am in Europe they don't do that anymore, it's usually cheaper to buy the phone from Amazon - if you can afford the up front cost.

Outdoor CO2 levels can go up to 700-800ppm in rural areas due to plants creating CO2 [1]. I was initially surprised it's that high but it was verified with reference instruments.

Why measure CO2 outdoors?

We are able to detect emission sources pretty well now with our outdoor monitors [2] that have the SenseAir S8 NDIR sensor built in. You can see some real data in the blog post I wrote about launching our global CO2 map [3].

So setting up a dense network of these sensors in a city would allow to measure if for example the introduction of low-emission zones or switching to electric buses etc. would work.

Another use case is to check for leakage in underground CO2 storage facilities.

All-in-all it's still experimental (to some extent) but we know the accuracy is there and we can see more and more use cases as outlined in my blog post. So we now work hard to get more and more of these sensors out there to get more data to identify additional use cases.

> The market has shown repeatedly that few consumers value no-tool battery replacements, relative to various other features they'd have to give up to get it. People are voting with their wallets and it doesn't make sense for Apple, Samsung, etc., to build phones people don't really want.

It costs those manufacturers next to nothing to make the battery replaceable. What is does cost the is future sales of phones, because now people could swap in a 15$ replacement battery instead of choosing between (1) pay 150$ for a replacement or (2) just get a new phone.

This isn't about the market not wanting to pay the extra 5$ it would take, this is about the manufacturer deciding there is more money to be made this way.

We never truly had a choice. The fact of the matter is people's choice of phone brand is sticky, and manufacturers abuse that. If you've had the Galaxy S5 and needed a new phone at no point did you have the choice between an S7 with or without replaceable battery. It's get the S7 without, or screw you - get a worse phone.
> Again "killing oneself" is never the answer.

While well-intentioned, such blanket statements oversimplify a complex issue and are ultimately counterproductive. This topic deserves more nuanced discussion, especially on a platform known for thoughtful discourse.
I'd believe more in a heterogenous chip (e.g. MI300X, Apple M series, or even APUs) than in completely new chip tech.
Because contracts that people sign when they buy a subsidized phone are not really enforceable. Folks will get a "free" phone and stop paying. There is not much that provider can do. The cars are valuable enough and when you stop paying your loan you will lose it pretty fast.
Poor people offen do not have access to credit lines, it's much easier and beneficial to just have cheap products available for those that need them. There's no reason phones should cost $1000 or more anyway, they aren't worth that much.
A) This isn't what OP was asking about. They're pretty clearly asking about stolen devices from a consumer, not consumers stealing devices from carriers.

B) Your take is complicated by the fact that there actually is a secondary market for locked phones [0], so this isn't just about people rent-to-owning a phone with an explicit installment plan.

I've only got a physics minor, so hardly an expert, but I felt like quantum mechanics got a lot easier once I started thinking of a particle as merely a situation which has some probability of causing a state change in a detector of some kind.

Protip: Call Verizon and tell them refusing to unlock your fully-paid for phone can be considered theft in your jurisdiction and can result in criminal charges.

They'll unlock it very quickly. The techs aren't legal geniuses.
As a developer working in fintech and other traffic-heavy industries, I constantly ran into the issue of platforms like Facebook flagging or shutting down my more aggressive marketing campaigns. This led to wasted time, effort, and budget.

Frustrated, I built PageArmor, a tool that helps protect marketing strategies by blocking unauthorized access, bots, and prying competitors. The goal is to keep campaigns running longer without getting caught in the usual platform filters. It’s been working well for me, and I thought others might find this concept interesting.

I'm curious if anyone else has faced similar issues with their campaigns or come up with other creative ways to stay under the radar. Happy to share more about the technical challenges of building this or hear about others’ experiences.
It would be really amazing if you could expand your workflow a little, especially how you have stitched everything together.
Qualcomm is not the most dominant chip designer in basically any market section. Intel is the worst of the best fabs.

Still, I think there would be some serious antitrust scrutiny.

They might let Qualcomm take the Intel design business but make them split out fabrication. Qualcomm might not be interested in that offer, thoguh.
At least on the 4g days there was such a thing as a lost and stolen device database that was shared between providers. When the phone presents its IMEI to the network the process that checkes it’s subscriber status also checks if it’s IMEI is on that block list.
I absolutely loved that game on Xbox. It's the only reason I own an original Xbox.

It came out when I was just branching out into the world without my family around, and seeing a game where my choices changed my appearance was kind blowing to me.

I still love this game, though the replayability was definitely overhyped. It's pretty much the same every time.
If 1 lonely person speaks to another lonely person, you now have 2 less lonely people.
If 1 lonely person speaks to a chatbot, we still have 1 lonely person.

Of course, people making the chatbot would argue that if everyone just used the chatbot, nobody would be lonely.

I believe that relieving loneliness through personal connection is an exponential benefit (I'm not sure I have the right language there). Each connection which is added to the network described above, increases both the value, and reduces the load on any one individual. Yes, there is a maximum, nobody is going to have 200 close friends, but in social circles, there are connectors who bring multiple circles together.

Rather than build chatbots to battle loneliness, there is value in building something that an help people find and build connections, and maybe that is what the AI will become, more of a concierge to connect people rather than the connection itself.

Who's working on this?
It’s carved wood — hard to scale up!
> or if you are lucky authentic ones that for some reason ended up there (but I can't imagine a way).

Chinese fabs are notorious for running secret shifts that make their customers’ chips to sell themselves. They’re the exact same chip but made without authorization, using the customer’s exact design.

That said, Sensirion has their own CMOS fabs in Switzerland so that’s very unlikely to be the case here. If they work at all, the counterfeit chips are probably some Chinese CO2 sensor IC that's small enough to fit into the same package, lightly customized to fit the pinout of the original. Or it's just a microcontroller inside faking it a la FTDI.
I wonder what it was like putting this type of technology through the A&A process. Did they choose a Python-based software stack? How have they approached the supply chain threats present in the Python ecosystem?
... It always felt more French to me.
I'm in an MBA program and in my data science course (aimed at non programmers obviously) the prof used R and Rstudio.

At first I thought it was a bad choice, and I did all my assignments with Emacs/ESS. I preferred it, as I do almost all my coding in emacs and of course it's easy to define custom shortcuts to insert the un-ergonomic R operators like the magrittr pipe. But I came to realize that the way Rstudio is self-contained, and oriented around "sessions", or notebook-style code, makes it easier for neophytes to pick up.

I can't imagine how difficult it would be to teach a bunch of non programmers how to deal with python given the insane situation with venvs, pip vs homebrew, and 2 vs 3, imports, etc. 80% of my cohort are the type of people who think using the terminal constitutes "hacking" in the CrashOverride sense.
I'm disappointed in rpg's now. Once oblivion came out, they all seemed to stagnate and just be clones of that model.

The problem is the market for a deep, deep rpg with skills based on time spent using them is probably pretty small. Because it's people like me who don't actually have the time needed to play them due to life nonsense.

I desperately want the mechanics of Morrowind, but with modern graphics. The original is almost unplayable because of how crappy the graphics are.
I don’t see how yours are theories as they don’t seem to have any relation to the underlying anything, or have anything testable per-se. Frankly, I’m struggling to see how they’re even hypotheses?

I could see how adding a few sentences onto them could result in such things. Which is why I’m asking for you to elaborate.

After all Hurtful != lonely or depressed. Problems existing != lonely or depressed.

We’ve always had problems of some sort. I’m unaware of any time in history where someone didn’t have something nasty to say about anyone, or there wasn’t something bad potentially happening.

Lonely or depressed tends to happen when someone is isolated and/or feels like there is nothing they can or should do to resolve an existential issue.

Depression tends to be the ‘I should hide in a corner and pretend I don’t exist’ survival strategy.

Not necessarily because there is a problem in general.

But the issue is unlikely to just be ‘living at home with the parents’ still, since in Europe and Asia that is and has been a thing for a very long time, and we don’t see such an epidemic there eh? (Or do we?)

My personal theory is that the problem is less ‘the problems’ - rather that our increasingly sedentary/isolated lifestyle is leading to a downward spiral where we’d rather bitch about/ruminate on problems (and ramp up anxiety fear to try to get moving) than actually solve problems and move on, or even just accept problems and live.
You missed the part where this is slow as hell.
Tell HN: The Unavoidable Ladder
I was reading a software book earlier tonight that used the phrase 'technical glass ceiling', and it reminded me of an important realization I've had about IT recently: a realization about what I'll call 'the unavoidable ladder'.

In the book I was reading the author used the phrase 'technical glass ceiling' to denote a ceiling that exists for technical people who don't have the required social skills for management. But I'd like to offer a counter-perspective to this outlook.

The 'unavoidable ladder' is a phenomenon that exists for business people who have social skills, but minimal to no technical ability. Because of their ability to deal with people, and because they work in the management stream, they're consistently being identified for promotions and additional responsibility. Lacking hard technical skills means that they're unable to work in the technical stream, and can't avoid brushing up against the political world of the business.

Where those who do have technical skills, and who do work in the technical stream usually have much less stressful jobs, where they sip coffee, solve technical problems, and listen to music. These jobs aren't open to those on the unavoidable ladder.

So maybe the managers and directors are making good money, but are they really enjoying themselves? Developers usually are.
Oh wow, that's a great personal story.

I would imagine things begin to improve around 2000 due to the broad adoption of unicode? I remember there being an absolutely huge number of encoding systems for the various CJK languages back then, but I think Windows eventually guessed/settled on UTF-16 IIR.

I didn't live in Asia during this time, but was heavily involved in writing some multilingual capable desktop windows software and was very aware of these challenges. I remember one colleague who worked on our Chinese language material having to buy an expensive copy of a Chinese British telegraph code book.
This is so cool! From one random internet person to another: you can do it!
Yes but the Sacklers would have no income if they're languishing in jail stamping license plates. That means less money to pay the people who brought cases against them. Think about it. Liabilities don't just take their wealth, but their future wealth too.
Bootstrap moved from <label><input></label> in 4.0 to <input> + <label> in 5.0 for radios/checkboxes [1]. I was curious about why but my guess is that it adds some simplicity for theming when repositioning/padding either the label or input.
