> Where are you getting those numbers? I think situation is much more complicated, than your give it credit.

I explained this upthread.

Glibc apparently supports 4 distinct subsets of extensions for x64 according to this article about them removing a 5th one: https://www.phoronix.com/scan.php?page=news_item&px=Glibc-Dr...

Most code isn't glibc and would be fine supporting just 2 distinct subsets of SIMD extensions for x64.

> See https://raphlinus.github.io/rust/simd/2018/10/19/fearless-si...

I haven't looked into these Rust SIMD libraries much, but it sounds like they are doing worthwhile things. In 2022 you can also use Google's Highway if you are able to integrate template spaghetti into your code, but it's understandable if one cannot do this.

> It's still dropping down to assembly and having to worry about arcane details like endianess and byte alignment.

You don't have to write assembly. In Zig, you can just use binary and unary operators on vectors and get new vectors without using any intrinsics, but you'll still need to use more than 0 intrinsics for string parsing because you probably want pshufb. In the case of pshufb specifically, and this is representative of most of this stuff, the entirety of the complexity that you pay for having one AVX2 target and one SSE4.1 target is that the SSE4.1 target needs to get by with a half-as-wide pshufb. One way to do that (which might not be the best for all uses of pshufb on the SSE4.1 target) would be to write the wider pshufb in terms of the narrower one. Here it is:

extern fn @"llvm.x86.ssse3.pshuf.b.128"(a: u8x16, b: u8x16) u8x16;
pub inline fn shuffle16(a: u8x16, b: u8x16) u8x16 {
return @"llvm.x86.ssse3.pshuf.b.128"(a, b);
}
pub inline fn shuffle16x2(a: u8x32, b: u8x32) u8x32 {
const ret: [2]u8x16 = .{
shuffle16(@bitCast([2]u8x16, a)[0], @bitCast([2]u8x16, b)[0]),
shuffle16(@bitCast([2]u8x16, a)[1], @bitCast([2]u8x16, b)[1]),
};
return @bitCast(u8x32, ret);
}

simdjson's structural character indexer just uses a 64-byte-wide version of this operation, so that's 4 independent 16-byte-wide pshufbs, and it will be 4 instructions for SSE4.1, 2, for AVX2, or 1 for AVX-512, but if we do what I've suggested and don't have any particular support for AVX-512, it may end up being 2 there too.

Endianness is not arcane, but everything is little endian anyway. The penalties for unaligned access on the CPUs supporting the sets of extensions I've arbitrarily chosen are modest. You probably won't end up with a slow text editor just because your inner loops are frequently paying 1 cycle of latency for unaligned SIMD loads, but you can certainly fix that if you like.

> Is it? The more you use arcane features of code, the more computation you put out, and hence more heat.

Can you explain to Daniel Lamire that he is incorrect about this topic, and in fact it is more energy efficient to implement memcpy with 1-byte loads and stores than with wider ones? Thanks.

> I didn't say they do. I said they leverage CPU+GPU. And for average program to achieve the same, you need GPGPU.

Average programs want to compute many orders of magnitude less stuff than games though.
Weird that you think saying "democratically managed" somehow fixes the principle-agent problem.

Voters don't write code. There is a process that goes from votes to personnel decisions to design decisions to writing patches. This process involves people who have their own ideas about how to interpret what the voters might theoretically want. There is lots of scope for them to make decisions you wouldn't like.

It is interesting to think about energy efficiency, but we should also consider carbon efficiency, which often conflicts with energy efficiency.

For instance, if this old machine is connected to a solar panel, then its operational emissions will be 0 gCO2eq/kWh (grams of carbon dioxide equivalent per kilowatt-hour of electricity) if its consumption is kept lower than the solar generation. If it is connected to a greener grid like CAISO, its emissions will be mostly green (~ 0 gCOeq/kWh) during afternoons (~ 12-6pm).

Sure, at browner times (6pm - 6am), this old machine should be turned off (unless there is wind coming to the rescue). But at greener times, it should use the excess energy that comes from renewables and that can't be stored to be useful elsewhere.
> Having centralized aspects does not diminish the decentralized aspects.

There aren't any. "Decentralized" is just an in-group smurf word with no legitimate technical meaning, and which is not in any way a meaningful goal.

I have the same problem. Except that I get my 8 hours. I get enough sleep but I'm missing out on a lot of morning activities with other people. My problem is that I won't go to bed until I'm sleepy. I always feel like I'm missing out if I go to bed earlier than I have to so I wait until I can't function anymore. That's usually 2 or 3 in the morning.

Funny you write about your situation since I'm working on my ,hopefully, solution. I've tried some of the same things as you but I go back to the same routine. I've decided to get rid of all distractions in my room. No TV, no phones and even a clock. I have an echo that I can ask the time if I need it. No caffeine for now. A book to read. I'm also blocking out all natural light in my room and replacing it with a lamp the mimics sunrise and sunsets.

We'll see how it works. My plan is to get to bed by 10 and up by 6:30 or such everyday. So I will start to get ready an hour earlier. Saturday and Sundays too. I've also added a daily stroll at 7 am so I don't feel like I'm getting up early for nothing. I think that part of the fix is making sure to stick to a routine and not deviate. Since I'm bound to fall back to my old routine over time. I hope it works.

Maybe you can get some ideas from my solution.

Intel is playing with rabates/rewards to this day, often bigger retailers receive free Intel products for hitting sale numbers tuned in a certain personalized way forcing them to push Intel only.

This case shows that owing $1B dollars is not the problem for the one that owes the money, but for the party being owed. $1B buys you a LOT of top lawyers to argue your case to death, sooner or later you will be able to pay someone off to make it go away.

Problem with Jira: Its customers are not its users.

My past managers had a great time with Jira.
But if I have to migrate or create tasks in Jira the only efficient and effective way I have found is paying for a desktop license. It doesn't suck -- that much.

Otherwise, it is a destroyer of productivity for its users. It is also a source of lock in, that is usually unnecessary.

I find Github projects to cover most if not all of the needs, for instance, in an efficient manner. Most managers though also don't/shouldn't care about the micro tasks of a project, so an excel sheet has done that job.

The consequence of who the Jira customer is, is its lack of efficiency and chaos. It is too customizable and fails to preserve any form of usability to offer that customizability. I have seen Managers being joyful of achieving the "ultimate Jira," only for everyone in the team to have to learn to abide by the new process, only so that 1-2 people can keep track of tasks and velocity without hitting github or gitlab.

You get great statistics, but if I have to spend 1/5 of my workweek on petting Jira, you lose that.

Managers love Jira, that is why it keeps coming up.
You need one new manager to come in, say they know Jira, and using it will solve all of the company's velocity issues, to end up with people writing articles of how they hate Jira.
The SEC docs and the docs posted to a company's investor relations page always seem to match... so unless the company and it's auditors are in on it (rare), unlikely.

An accounting class, it's worth it. Burn is practically synonymous with operating cashflow (at least when negative..) and is always inclusive of revenue, never inclusive of non-cash charges (like options/equity comp).

Pointing out operating expenses as though it's burn suggests a lack of accounting basics. What's next? Google is burning $70 bill pa? Plus, loads of people on HN have either been involved in startups, or investing, or both. It's pretty silly to assume they haven't.
> Whether a specific viewer will receive it as political is a fact about the observer, not the piece of art.

That’s your key point. If someone wants to see politics in a work of art for which the artist imbued no politics of his own, they will find it. If someone wants to take offense to a statement, they will, regardless of speakers intent.

And so this really is a pointless discussion when you are saying that an elephant can be interpreted as a mouse, if the observer perceives it as such.
I can assure you there absolutely are. When you need to handle billions of requests a day (like a worldwide seller must), then it works.
>This speaks volumes about the need of standardized encrypted cloud storage protocols

I worry this then just means government actors only will need to find 1 vulnerability to have open access to a standardized web and those vulnerabilities will exist, nothing is perfect. I genuinely believe a non-standardized approach is more effective even if they are each more vulnerable individually.

Android presents a decent corollary here vs iOS. Finding an iOS device exploit may cost more money but you get access to such a massive amount of devices it is worth it.

Having an accurate location is important for emergency services. If you’re on a phone call trying to get an ambulance for someone having a seizure, or reporting a fire, shooting, whatever, it’s important to get the accurate location straight away.

If the call centre person misheard your location, but the code is still in Paris, they will think it’s correct and dispatch to the wrong location. It would take too much time after realising the mistake to get the correct location. So with w3w it is far more obvious when these issues happen as suddenly the map is showing as Middle East or Asia, not Paris!

I don’t think an emoji checksum would help here either. Wink. Was that a tongue wink or smirk or etc.

(Full disclaimer: I don’t see the point in w3w either. It assumes people are prepared in advance to have the app on their phone, otherwise if they need to download it/visit its site they have internet so there are better ways of getting the location)

Yes, it is a problem in general. It is inherent in the system that issues grant money and permits publication according to the opinions of the "old guard" in each field.

Recently, the Younger Dryas Impact Hypothesis, finally firmly established in 2018, was fought tooth and nail for a decade, with numerous shamefully disingenuous papers published (e.g. insisting melt-glass grains were pollen). The de-facto curator of the Wikipedia page, a retired historian with no geology background, did and still to this day does his part to throw up doubt.

It's been a problem with flight sims since day one.

Each "controller" be it your mouse, a joystick, flight yoke, game controller, etc, all have a different amount of available deflection on the physical device, and that has to be translated into deflection in-game.

Take a flight yoke for example - you might have say 120 degrees of rotation available physically on the device, but the actual aircraft has 180 degrees. This means the sim-pilot doesn't have a connection with what is happening in the real-world vs what is happening in-sim, making minute changes a lot more challenging.

It's even worse for things like joysticks that have a very low available deflection already. Moving the stick a few mm's could result in an uncontrolled roll in-sim.

To help mitigate this, most sims offer a scalable conversion factor for controller input, but it's never perfect.

> In real life, there'd be feedback on the flight stick or yoke due to all the air hitting the control surface

Also, not all aircraft are direct linkage anymore, and most (all) commercial airline aircraft (your Boeing 737, 787, 777, Airbus A320, etc) will either have simulated feedback or no feedback.

> Implicitly this entire discussion is taking place in the context of airborne particulates. Obviously no air filter is going to work very well against, say, gamma radiation.

I'm perfectly willing to consider gamma radiation "not particulate". But if we restrict ourselves to considering particles that have mass, the retention rate at the MPPS of any usable air filter is still going to be zero. The diameter of a water molecule is 0.000265 μm. This is significantly smaller than the diameter of an oxygen molecule at 0.000346 μm. Of course, I don't expect an air filter to remove 99.95% of the oxygen in the air. But I do expect the fact that oxygen molecules are airborne particles to be taken into account when we talk about the retention rate of airborne particles. Another commenter has stated that "particles" must be identifiably liquid or solid, but you can easily have an ice crystal of 20 molecules, which -- if it were a straight line measured along its length -- would still have a "diameter" of less than 0.01 μm.

So I don't understand how appealing to "but we're only talking about particles" is supposed to save this. Particles are, at their lower reaches, very small, much too small for an air filter to address without killing the user. It seems clear to me that any workable filter standard must define a minimum particle size below which filtration is neither measured nor desired. What is that size, for European filters?

>> But obviously measurement is not actually done at the most penetrating particle size, because retention at that size would be indistinguishable from zero. [...] If the MPPS is given... what is it?

Something's gone wrong... you've run together two completely separate comments as if they were related to each other.

>>> If the MPPS is given... what is it?

You quoted a standard that specifies a certain level of retention "at the given Most Penetrating Particle Size".

That wording explicitly states that the Most Penetrating Particle Size is defined by the standard ("given"). So, what is the MPPS?

At least for my undergrad (CS, at www.epfl.ch), the answer was basically "more math" (2 years of).

The usual generic answer was "it's approximately like a US master's".

And at least for the EPFL today, they've essentially formalised your suggestion and that master's equivalence: you get a "bachelor's" after 3 years. And you can optionally continue 2 more years and get a "master's".
Yeah, I agree. I think that what3words hasn't spent enough effort on this, or perhaps is suffering from trying to cram everywhere into 3 words, which means the wordlist needs to be unmanageably large.

Even for my attempt at the problem, I did various experiments on the word list, but an ideal attempt would check for similarity across common accents, etc and I certainly wasn't able to do that.

Having said that, I think it's a valid and realistic goal for good word encoder systems to aim for good roundtripability via voice or memory.
My comment was extremely flippant. Let me provide an example to explain my point of view.

Cancer research can appear very stagnant. Pharma companies and researchers funnel money into existing solutions and combinations of existing solutions which increase life expectancy by a few months, and quality of life by a few degrees. Not much foundational research on cures, and why should there be when every new drug which leads to slightly better outcome will be purchased by patients who will do anything to live a bit longer?

Now, how in the hell would VC be expected to improve that landscape? The ideal solution is a cheap therapy which cures cancer. Maybe a cancer vaccine. Where's the money in a 50 (or even 1k) tailored vaccine to cure a cancer when a slightly new combination of cancer drugs can cost $50,000 a month for the rest of the life of a patient?

I'd argue VC don't think long term for the benefit of anyone except themselves. They'll invest in a moonshot if it disrupts an industry for their benefit (e.g puts all taxi drivers out of work) but not if it eliminates an industry (e.g cancer research). There's way more money in funding a slightly different cancer drug.
