Some GPU assembly advancements...

* Bpermute and permute. (Pshufb is like permute, a gather operation. Bpermute is the opposite, like a scatter. Bpermute Doesn't exist on x86 yet)

* __shared__ memory crossbar: every simd unit can read, or write, to shared memory in parallel per clocktick. The crossbar can also broadcast 1-to-all each clocktick.

* Butterfly permute: the fundamental pattern in permutations for a variety of operations. Most noticably for scan, and FFTs. Butterfly networks are closely related to pext and pdep implementation (showing how common that particular permute is).

* 8+ way hyperthreads / SMT. GPUs have very bad latency, but very high SMT counteracts that problem well in practice.

* PCIe Atomics: perform those compare and swap negotiations over I/O, allowing tight CPU and GPU memory integration.

* Crazy RAM. 1000GBps on HBM2. 800GBps over GDDR6x thanks to 2-bits transferred per clock ticks.

* Crazy networks. AMD Infinity fabric pushes over 100GB. NVlink is 600GBps. A GPU network link has more bandwidth than a typical CPU's DDR4 RAM bandwidth.

* NVidia SASS has the craziest instruction set, the compiler figures out read / write hazards and publishes them in the SASS assembly itself. NVidias ISA decoder + assembler team is doing something crazy here, the likes I haven't seen in any other instruction set ever.

* "Ballot" instructions. Its... really hard to explain why these are useful. They just are, lol.

Just a few cool concepts I've seen in the GPU world recently. Sure, matrix multiplications get the headlines because of tensors / deep learning. But don't sleep on the obscure stuff.
That solves the botnet/tracking aspect, but doesn't solve the "I want a computing device that I control" aspect.
Let's get a right to repair bill done. I don't think this current administration and congress have an appetite for it, but maybe in the future we will get it.
>...And [the computer industry] stopped manufacturing [a computer that is not designed to maximize computer industry profits] because ...

When you read it back, it sounds silly to expect any company to make products that ever fit this criteria. Except expensive ones, of course, which maximize profits in their own way.
And by the downvotes I'm getting I guess others agree, haha.

But before this moment, I personally would've definitely classified semis and RVs as "cars".

Public services are kneecapped in this country because non-white people use them.

Same reason why we defunded public universities (imposing the student loan system) just as agitation was enabling women and people of color equal access.
Any organization that concludes the ideas in that article are hateful or harmful can really no longer be considered an academic one.
I was in a country that had pay toilets. What I observed during my trip was that every town had that one place where the coin mechanism just happened to be jammed, and the turnstile would give way with just a little push. I tended to pay anyway, but it seemed to be a practical solution. And that toilet tended to be a bit more dirty, probably because it was more crowded but cleaned on the same schedule as the rest.

The free toilets at freeway rest areas in my state are just fine.
Look at how many times spacex has drastically changed their hardware plans while designing something.

The track record of making things work is good, but it's a very different kind of problem when you're allowed to redesign.
Well, while I happen to have a sympathetic view of the author's plight, the goal ( and the tactic ) is not to change anyone's mind. Quite the contrary, the goal is re-entrench and have people rage against cancel culture. And it works. Facebook may have perfected it, but it does not mean a more elaborate click-baiting mechanisms were not adopted by humans. In fact, clearly, they were. Rage, sorry, engagement, sells.
Love it! Hope I get to hear it in the club / festival one day!

As someone who comes from a working class background, I hate this system. Credit is something that ought to be abolished in its current form. Credit card companies and banks abuse this system to offer overpriced loans to desperate people, and they oversell the convenience to working class folks, encouraging them to buy things on credit they otherwise couldn’t afford... Now they most likely will pay their credit card bill at the end of the month, but at the cost of not having any money for the rest of the month.

Moving to America I was horrified to learn that in order to get applicable for loans (including home loans) I had to “work up my credit”, which includes maxing out on credit cards and then paying it back. As a teenager I made it my philosophy (experiencing second hand stress from the people around me) never to get a credit card. Now if I want to have a realistic opportunity to buy a house here I’m forced to abandon this philosophy and to the thing that kept my mom in constant state of stress. This credit system ought to be abolished.

From my personal perspective, credit cards are a systematic way to bamboozle the working class into over-consuming and keep them in constant state of dept. And to reward the wealthy for the same behavior, which only serves to shove it in the face of poor folks that the rich get away with everything. This system ought to be abolished.
So, just as I can store an encrypted file in the Cloud and nobody can tell what it is, we can have a computation happen in the Cloud where nobody can determine what it is?

Those two things don't mean the same thing. Hillary Clinton won the popular vote, Trump did not. The sentiment that the candidate who got the most votes is the rightful winner has limited correlation with Trump's stolen election arguments.

Yes, a J is technically a Ws (watt-second).

Or more accurately, since Joules are the fundamental unit and Watts are a derived unit, a Watt is a J/s (Joule per second)

Well, devil's advocate here, but teaching a car to drive in good weather is hard enough, and has lots of applications! It doesn't seem totally unreasonable to focus on that first?
“CPU Intel Core 2 Duo SP9400 2.40GHz. Upgradable to SP9600 2.53GHz.”

This rules... I advocated for a similar approach with take home tests at my last position. I used this on candidates and never had a bad hire. Unfortunately this approach was overridden by more senior management in favor of on-site technical tests (programming tasks, IQ and whiteboard problems). The prevailing wisdom was that you couldn't trust people not to cheat on take home programming tasks - a proposition that I find entirely ridiculous and in any case would be quickly mitigated by the on-site code review you use.
It is banned, thats why they use the workarounds. Prohibition frequently doesn’t eliminate.
In all fairness most users are willing to trade their privacy for access or features. Most users already give away almost all of their rights and accept terms of service blindly so they can access sites.
It really should be that way - i.e. we agree that standards are a net good (and I don't think anyone would argue otherwise) for industry and society, so make them free at the point of use and fund their development through government.

This removes any commercial incentives that may result in regulatory capture - a big issue in some areas - and should (if implemented properly) drive investment in strategically sensible areas.

The profit that most national/international standards bodies just about covers costs, but none of these bodies are particularly expensive to operate in the grand scheme of things. Some already get partial funding from govts. Full funding is clearly the sensible model.
This feels like it was made to get to the top of somewhere like HN but I'm actually very confused.

>I want it to be, but which can also be used to communicate securely with anyone on the planet without being observed by a third party. I don't want to be spied on by Microsoft or Google.I don't want the NSA intercepting my conversations or even their metadata.

I don't see what this has to do with the actual computer honestly. You don't want Microsoft to be involved so I'm going to assume you are going to install Linux on whatever you get, awesome, this doesn't stop the NSA or Google from harvesting your data because that doesn't really have anything with the computer. Seems like you want a search engine and ISP that you own as well.
How many degrees of separation can you get in here and still feel justified?

Kunin opposed the idea of blacklisting in general, he didn't even endorse any person.

So now, for those who refuse to be published in the same magazine as him, the chain goes "unspecified other" -> Kunin didn't disavow -> they can't publish anything where Kunin might also publish? There's not even a specific idea they're condemning besides general open-mindedness.

What about if the magazine had allowed him to publish, and you had been in there as well? Would you deserve censure as the third link? After all, you shared a stage with someone, and god only knows how many stages they've shared with how many people.
> I think what a lot of the commenters are missing is that this article, and statements like "If I must revise my teaching to conform to a popular view of inclusivity that I do not share" have an impact on not just his research, but also sends a message to his students: that he doesn't whether they feel safe being there matters, and that they don't deserve to have representation in studied works.

You're making a jump there: from whether Kunin's class covers works from authors with certain demographics, to whether his students feel safe. The character sequence "saf" doesn't appear in either of Kunin's articles. I think if it had been conveyed to him that his students' feeling of safety depends on his choice of curriculum, then he would have mentioned this argument (he'd probably call it absurd but I expect he'd mention it). His impression was: "That way, students from underrepresented minority communities will see themselves reflected in the readings. The students will feel included, and empowered to succeed, when they read works by writers who look like them."

Do you think it's really true that a significant number of students were feeling unsafe as a result of curriculum choices, and if so, why hadn't Kunin heard of it?
Santosh Vempala is also considered to be a genius, at least in the statistical learning community.

I'm not sure what the point of that link was, either.

But I'd point out that America has A LOT of blood on its hands. A half million Iraqi's being the most recent, Vietnamese before that, and Koreans before that. Still going strong with drone strikes. Banana republics in central America, mucked around in south America. Proxy wars in Africa. Keeping the Middle East destabilized. The average American seems to support all of the above, which just means it will continue.

I don't want to say that America is an evil country, but it is the biggest and violates the rights of a lot of people (to say the least) in pursuit of its interests. It's an empire warping the world to its desires. Economically (as you mentioned), culturally, and militarily. That's what big powerful countries do.
Does the Chicago Review position itself as an academic organization? I'm under the impression it's a literary publication, which seems pretty different than a research publication in my lay eyes.
I don’t like public services because every time I have ever used public services, even extremely (excessively) overfunded ones in liberal coastal US cities, they have had mediocre to extremely shitty quality from the perspective of the consumer.

Services aren’t supposed to be jobs programs. I like privatization as a rule. It has nothing to do with racism, it has to do with an intense dislike of being fleeced by politicians.
This points to another issue I've observed is that managers/operators ask for an effort-estimate and then map that directly to calendar estimate.

That and thinking that two 4h efforts can be completed in one 8h workday. MFer interrupt work so frequently how do they forget it happens? Forgot you had me in that BS 2h sales meeting "for show"!?
I think gp is just talking about theft/robbery in general without specifying the type.
> this time they have a Native American employee, you, that they can talk to about how to reach out to that group.

I remember reading someone's opinion basically stating that things like that for underrepresented groups are unpaid emotional labor, which I kind of agree with - it's got to be a weird position to be in to be hired to write code and somehow end up as the defacto sounding board for questions regarding the company's interactions with people similar to you. Imagine having randos come up to you and ask you for your time to pitch new ideas for how to recruit white dudes or asking questions about how it was growing up a white dude or even just people making the assumption that since you're a white dude you care about hiring more white dudes.

> what other process would we suggest?

Personal opinion alert: I feel like a lot of (not all) tech's diversity problem is a pipeline problem so maybe identifying people that belong to underrepresented groups out there doing good work getting folks from the group interested in cs/tech and then giving them more resources?
If I'm reading this correctly, they showed a series of pictures, one at a time, and told people to focus on faces that they found attractive. They then recorded EEG data to generate a score of perceived attractiveness, and used it to influence the GAN to make more beautiful faces.

This is a very weird approach. If the goal is to personalize attractive faces, you could just have subjects rate pictures on a scale of 1-100. If you want to test EEG ratings of attractiveness, you should just compare manual ratings to EEG ratings without prompting them to focus on attractive faces.

In all likelihood, the EEG has no idea if you think a particular face is attractive. They've just trained the AI to recognize when a user is focusing intently vs. not. Which is still kind of cool, but much less interesting than the headline suggests.
Despite the high probability of it leading to some weird dystopia, I suspect some government will try implementing a national ML-powered dating service at some point (especially if birth rates continue to drop in developed countries). Two examples of governments getting involved in the dating market are from Japan[0] and Iran[1].

The hardware is also suspect. I think in the author’s mind we need an entirely new computing architecture.
Lots of art is political. But what makes art good has nothing to do with its politics.
And?

I suspect customers that asked you to, say, build a new inventory tracking tool that interfaces with their existing enterprise infrastructure (SAP, Salesforce, etc) didn't ask you to do it in 2 weeks.

So what was asked was probably -reasonable-. If it wasn't, you probably would have dropped the customer/left the company out of frustration.

If it was reasonable, for a sufficiently fully featured solution that you COULD drop features and still have an MVP, then I would fully expect you to do so.

That's PM Triangle 101; you can give on features while keeping cost and time fixed.

That's just how we handle the fact that estimates are wrong, but we have to keep a date (we drop features, or bring on more people if the work is sufficiently parallelizable). This article is about the estimates being wrong.
Not really enough volume you could only use the lowest levels, and even the largest mines are dwarfed by small lakes. You'd have to put the generators and pumps at the bottom where they'd be easily submerged.

Typically pumped storage uses two lakes, one high and one low. But points for creative thinking :)
What do we own though? (Heck, we don’t even own our bodies - they are “owned” by the nature, which can often be pretty “evil.”)
They're not looking very hard.

Universities have departments full of grad students and postdocs that can code and analyze data: programming and ML are increasingly common tools in neuroscience, biology, psychology and a number of other fields. However, these people are mostly invisible to tech recruiters. I hear from one or two a year and I think that's on the high end for my neuro department (having a CS degree also helps).

It might take some work to find a way to make academic achievements 'legible' to industry, or to sell industry jobs to people, but whoever figures it out (besides Insight) is going to make a mint.
It is impossible to solve systemic bias by using discrimination. It has never worked in the past despite an untold number of attempts. In a very similar way, violence create violence in very predictable cycles.

Like violence, the solution to systemic bias are simple but unattractive. Don't display and rub symbols in people faces. Do not create ambiguous borders between groups of people. Treat each person as individual and avoid generalizations. Add social and economical support based on lack of those resources on an individual level, from the bottom up.

The progress towards equally would look very different if people weren't constantly doing the opposite in the belief that this time the symbols will convince the enemy of the wrong doing, the ambiguous borders will work, the generalizations will send the important message, and that top to bottom approach will create a foundation for change.
The text says one thing, but the graph they display to support their argument does not say what I thought it said.

The purple line is supposed to be our "real" emissions, and the impression you get from the image and text is that our real emissions are much lower than the projected emissions.

But if you actually look at the values of the purple line vs the other lines now, in 2020/2021, the values are almost exactly the same.

I don't understand how to reconcile that with the text.

how do you burn neurons and why should i care about them?
Not the author, but I would say they might not be very secure, but importantly, they are _auditably_ so. You can look around to see if anyone shady is within earshot, and in many situations you can choose a (contextually) private location if you so desire.

Plus, it is a bit harder to mass surveil people, even with voice recognition, as one can go into a crowded place (or, well, could, barring current circumstances...) so most of the audio is drowned out.

This is epitome of what free software is. Get a system76 system. It'll have a web browser and wine for when you feel like using non-free software.

p.s. aren't Raptor Computing's systems pretty much free too?
"Villain", "odious ideas"? Name them explicitly instead of the usual general ranting employed by demagogues like McCarthy in the past and the left inquisitors these days.
Is this true though? Wouldn't it be rather boring if the standard model continues work? In the end, Josephson won. Even the example that the author here mentions with breast cancer-vs-skin cancer was eventually discovered to be wrong. The main question is the time scale.
That is the solution I am considering at the moment as well. Its not the prettiest, but it will likely work as a stopgap measure.
Where is the ship's wake? Even if this were the result of a mirage that makes objects appear higher than they are, there should still a wake in the ocean where the ship actually is. This photo is fake.
Agreed. I do know that ISO and at least two national standards bodies I work with basically do charge on a cost-covering basis (which is why pricing is largely tied to tiers of page count, which is a reasonable proxy in most cases to effort/time). But industry/hobbyists shouldn't really cover this cost - or should do through general corporation taxation.

To be legally compliant to install cables in the UK I've got £500 of standards on my desk. We actually pay our national body circa £5k a year for access to various industry standards we need to be able to hold suppliers to account. Govts should just properly fund this stuff.
I've been releasing my recordings as Public Domain on my website, but after reading this nightmare, it has me wondering what to do going forward.
I agree with this so much. It would be so convenient if I could just flash Arch Linux or something onto a modern smartphone and be able to use all the applications and settings and data I use on my desktop, but on my mobile phone. Android is markedly better than iOS when it comes to customization, but it's a far cry from a (real) Linux distribution. I've started getting OS-level push notification ads from Google News and other bullshit on my Samsung Note 9, and it makes me want to set the thing on fire.

It also makes me pretty pessimistic when it comes to privacy. I can uninstall Windows/MacOS on my laptop, coreboot it, use FOSS/privacy-centric software, etc. but it doesn't really mean much when my phone (which is basically attached to my body 24 hours a day, and is my main conduit of communication with others) is a privacy/security nightmare.

To be honest, I've always felt like this was an unproved assertion. Popper made it sound very good, but what attempts to show that it's actually true have been made?
