The main thing seems to be that we don't have general purpouse languages in common use that fit SIMD auovectorization in semantics, without carefully "code to the compiler" portable assembly mindset. Even after 25 years of x86 SIMD support in hardware.

It's just not been an aim even in more recent-ish languages like Rust, Swift, Go etc. Partly because of the unworkably hard task of targeting fragmented, undebuggable, proprietary driver/OS programming interfaces from POV of portable languages.
Yes it should be read as a placeholder for whatever you need to do.

Could be an array inside a struct too for instance, that is quite common.

Much better to do on the GPU.

In general wide SIMD on CPU has the problem that to make effective use of it, you have to massage your code enough that you are ~95% away from just running it on the GPU anyway, and you can gain much more performance if you do that. The best niche of AVX-512 would have been as the baseline common target for things that also get optimized for GPUs... except that Intel has eliminated this possibility by heavy product segmentation right from the start.
Well even the free models aren't free at scale. And if you're paying for the inference anyways you might as well pay for one in a model which was specifically truncated to your needs.

To provide some perspective here, SD can be retrained on comparably small samples to generate images for very specific needs (example see [1]). So there is certainly a bunch of $ to be harvested by generating very good training sets for industry needs, say for instance mockups in architecture, creating logos and brand styles or just nice looking designs for consumer products.

The WebMD article is referencing esketamine, also known as Spravato, which is an FDA authorized form of ketamine. It's generally indicated for longer-term use in patients with Treatment Resistant Depression (TRD), and has really good results on par with ketamine (IV or intramuscular).

At Lumin Health, we treat about 80% of our patients with esketamine, and the rest with ketamine (generally only if they don't meet esketamine criteria). After the initial course, patients tend to find a good balance of ongoing care that helps treat their particular depression / depressive symptoms. This happens less with ketamine since it tends to be prohibitively expensive to continue care (upwards of $1k/month).
I'll tell you what happens when someone writes:

sprintf(buf, "%d %d", f(i), i++);

They get told to rewrite it.
I use my Apple Watch Ultra for running, hiking, diving, health tracking etc.

So it's far more capable than just a dive computer.

If you live in a developed country, your contribution to the microplastic problem is minuscule regardless of the amount of plastic packaging you use. Landfilled, or better yet burned in industrial setting plastics don't get into the oceans, they are either fixed there for millennia, or don't exist anymore. Plastics are a non-issue for countries with functioning waste management, which is coincidentally the countries that can afford caring about it the most, so in a sense there is a self-contradiction in this debate.

International treaties forcing developing countries to get their waste management together combined with targeted investment there would help way more.
You're completely right!
VC's had money, i.e. capital. Now the money is gone. What would you describe that as if not destruction of capital.
I don't think this will be a useful dive computer for most people. When I first heard the Apple Watch would work as a dive computer I was very excited, but having spent some time thinking about it, and having done 20 dives since the watch was announced, I have changed my mind.

The first problem is battery life. I didn't have to replace the battery on my computer for the 20 dives over a week I did recently. If I had gotten a low battery warning, I could have replaced the coin cell battery in five minutes. With the Apple Watch, I would be uncomfortable starting a dive with less than 80% battery, which means remembering to charge it before every dive. If I forget to charge it, then I cannot quickly replace the battery, and I cannot switch to a backup computer if I hadn't taken it with me on my previous dives as it wouldn't know my tissue loading. Forgetting to charge the watch before any dive would mean missing the dive.

The 40m limit is not a good idea. I imagine Apple's legal department are forcing this one, but it's a really bad idea. I went slightly below 40m a few times last week, I know that breaks "the rules", but I know the risks and they honestly aren't that bad if you don't push things too far. Having my computer lock out, refuse to give me NDL times, depth info or deco stop info if needed is not a good idea, especially when you really need it at those depths.

There is also no mention of nitrox, so I assume it's not supported. That would make this the only dive computer released in the last decade that doesn't support nitrox diving. Nobody who is interested in owning a dive computer will want a computer that doesn't support nitrox.

The one good thing I see about this is the haptics. It's really easy to get alert fatigue underwater from other dive computers beeping around you. Haptics would be far better.

Are there any "self custody" or "decentralized exchanges" that offer 8% interest on deposits? I think you are comparing apples and oranges here.

What's interesting is it seems they're only putting up a a 3% bond from what I can see [1]. So it looks like people could just take 97% of your money and run.

Whenever a big exchange fails, we see a lot of people say "of course, this is why decentralization is better." But I'm not convinced people are less likely to lose money in decentralized exchanges. It seems like it would actually be easier, it's just that a bunch of small scale scams aren't going to get the same attention as a huge exchange collapsing.

The value proposition of decentralized finance was supposed to be a replacement for traditional finance: automating away the hundreds of manual roles that banks currently employ as part of their regulatory requirements and customer services.

Do you have a source that shows that a substantial percent of Kraken's headcount is customer service? They've tried recruiting me a handful of times, and each time they highlighted their voracious appetite for engineering talent (and corresponding rapid growth of their engineering teams).

As I said: Twitter was one of the largest social media networks on the planet, one that ran its own datacenters and independent ad business (along with moderation teams, service teams, etc.). I'm not particularly interested in defending a headcount of 7000 people; only that it makes far more sense to me than roughly half that number at a cryptocurrency firm.

"We do have significant exposure to FTX and associated corporate entities that encompasses obligations owed to us by Alameda"

I feel like the term "exposure" was intended as a euphemism, but it is now so thoroughly overused that I am developing a more negative reaction to the term than the words it was intended to hide from. "We had exposure to X" is starting to sound worse to me than "We invested in X and X lost a lot of our money"! The latter sounds like a reasonable thing that happens even to reasonable people but I'm starting to associate the former with more insane things happening to careless people.

But maybe that's just because of the sort of things I tend to read.
Partly.

There is a lot of people who buy these in very small quantities, myself included.

Bulk purchasers pay much less. The ratio of cost of single unit when buying one and a huge amount varies wildly from chip to chip.

My hope is most of the crypto investing was isolated to crypto funds, though I still lost some respect for VCs for even playing the crypto game.
GPUs are still an unworkable target for wide end user audiences because of all the fragmentation, mutually incompatible APIs on macOS/Windows/Linux, proprietary languages, poor dev experience, buggy driver stacks etc.

Not to mention a host of other smaller problems (eg no standard way to write tightly coupled CPU/GPU codes, spotty virtualization support in GPUs, lack integation in estabilished high level languages, etc chilling factors).

The ML niche that can require speficic kinds of NVidia GPUs seems to be an island of its own that works for some things, but it's not great.

> In fact, until 1889, "London" referred to the City.

Here's a Post Office map of London from 1857: https://mapco.net/kelly1857/kelly.htm

As you can see, it covers a much larger area than just the City.

19th century writers -- e.g. Austen, Trollope, Doyle -- use "London" to mean the metropolis as a whole, not just the City.

And Apsley House, built in the 1770s, was for years popularly known as "No. 1, London", because it was the first house you passed after going through the toll-gates at Knightsbridge (at the western edge of Westminster).

As others have posted, your estimates are WILDLY off.

First, fortune 500 companies dont own "two" mainframes, but a LOT more.

Next, many non-F500 companies own a lot of them as well.

Years ago I worked for a local cable company in Canada.

Not a "F500" company, owned at least two mainframes for the "head office" and each different 'subdivision' owned their own mainframe.

Try watching the evening news on broadcast TV sometimes. You occasionally see an ad for something buy out of their own pocket (particularly DTC startups) but it is almost all benefits you can get from medicare, prescription drugs, lawsuits you can join because your CPAP is trying to kill you, and personal injury lawyers that specialize in car crash victims. (I guess somebody has to advertise cars because if people didn't buy cars you couldn't get hit by a car and call William Matar but you don't see car ads until 8pm when prime time starts)

What's scary is that these people vote... And they want to get the government out of their medicare.

> Done on special-purpose hardware that is >10 times more efficient than any implementation on GP hardware.

That locks users in to only the codecs that have been implemented in this particular hardware, and increases hardware size for particular vendor implementations rather than provide common building blocks that many codecs use (DCT, ...)

> Much better to do on the GPU.

Yep and that's what I run ML stuff on, not all systems have a GPU available though, and for some applications it's faster to do something immediately on the CPU, than have the overhead of going to/from GPU

> In general wide SIMD on CPU has the problem that to make effective use of it, you have to massage your code enough that you are ~95% away from just running it on the GPU anyway,

Better tooling and libraries could help with this imho. Note that the situation for GPU is here also not great at all, since the good tools are locked into 1 vendor.

I don't think your experience translates well to everyone, hence the need for different methods.

I'm active in my community, politically active, have started and sold a business in the past, etc... and all I have are acquaintances. I don't think anyone outside of my immediate family even knows when my birthday is or how old I am.
Except we are developing artificial minds that are better than humans at particular tasks.

That's a bit different than inventing a car (which at that time didn't even promise self-driving, so your analogy is doubly bad).
That doesn't sound conspiratorial at all. All sorts of features drift from being 'luxury items' to 'no one will buy a car without it.' In my life time time this has happened with air conditioning, power windows, heated seats. To say nothing of mandated safety features.

I think the way auto makers have 'trained' their customers is by removing the granularity of customization. Back in the day, every possible option could be tweaked when you ordered a new car. I knew a family that ordered their van with (standard) upholstery seats in the front, but cheaper vinyl seats in the back (because small kids with drinks).

You can't cherry pick features now, you just get 3 or 4 trim packages: base / standard / luxury / luxury + sport. And base is so punishingly sparse it only exists to lower the 'starting at' price in ads.

And that level of indoctrination is nothing compared to the 60 years long campaign to keep most urban development zoned as car-centric sprawl.

You can definitely break a plastic fitting with too much tape. The tape and the plastic are deformable, and I’ve had taped PVC fittings effectively extruded by repeated installation with fresh tape (every time you install it, you need a little bit more). This effect will be amplified if you’re fitting is made out of a material more prone to creep like PVDF, PP, or Nylon. Granted, this isn’t a typical (or appropriate) use case, but it was a necessary kludge for a project I had.

You can get leaks with too much tape if it prevents you from reasonably getting the threads to seal. When this happens, you get a slow leak between the layers of the tape. I’ve seen water slowly bead out of fittings at 1000 psi due to this.

Also, too much tape can lead to contamination (the tape sticks to every piece of dust, lint, and oil in your workspace) and can make it easy to cross thread fittings (especially small plastic ones).
Yes, they are expensive. This is what prompted a lot of people to switch to alternatives like Padauk. They had supply issues, though :/
No, it is the same. Developing world would wish to have easier ways to make money. They wish to have big brands, good profit margin. They DO NOT have it.
