Yep, or the old GreenArrays GA144 or even maybe XMOS with more compiler magic.

One of the big questions here is how quickly it can switch between graphs, or if that will be like a context switch from hell. In an embedded context that's likely to become a headache way too fast, so the idea of a magic compiler fixing it so you don't have to know what it's doing sounds like a fantasy honestly.

icodestuff · 8 months ago

Yep, that’s definitely the question. The article says that there are caches of recently used graphs for use in large loops. Presumably those are pretty fast to swap, but I have to imagine programming a whole new graph in isn’t fast. But maybe the E2 or E3 will have the ability to reprogram partial graphs with good AOT dataflow analysis.

Nice, this somewhat reminds Apportable: https://www.ycombinator.com/companies/apportable

icodestuff · 2 years ago

For sure. Pretty similar problem space, very different implementation and target market. Apportable wasn’t a transpiler (and boy were we proud of that); it was a reimplementation of the iOS frameworks on top of a replacement NDK (Android’s libc was bad-mediocre at the time. Real nasty behaviors in its (dl)malloc for instance). Similar to WINE. It was always targeting games, so there was never a lot of effort to port any of the UIKit controls, but OpenGL CoreGraphics were supported. It also had a compiler extension that let you access the whole Android SDK in ObjC, and a tool for generating ObjC APIs from JARs. The goal was to make ObjC the one true mobile dev language. I applaud the effort to do something similar for Swift, even if it does involve transpilation.

While the large sample size and many controlled variables are good, and make the results statistically significant, the effect sizes are awfully small. Only two of the emulsifiers, tripotassium phosphate and guar gum, increased the hazard of an individual developing diabetes by more than 10% (11% and 15% respectively, with very large error bars in the latter case). These are much smaller effects than previously known Type 2 diabetes risk factors.

For instance, the HR for family history of diabetes is 4.46 (vs 1.03-1.15 here, where 1.0 is no change in hazard).

Do the other emulsifiers from the study in this article contain PUFAs? If not, then then there's probably some other cause. Maybe PUFAs from other sources + emulsifiers, maybe something else entirely. So to the delight of the researchers applying for grants, this needs more study!

icodestuff · 2 years ago

No. None of the ones with an increased Hazard Ratio are or contain them.

The researchers also did not control for PUFA consumption, only SFA consumption.

> Even Super Mario World[10] got the treatment (I can't remember slowdowns but I was only twelve can then).

Yoshi’s Island 4 has a slowdown in some circumstances (have Yoshi, get Starman and hit P-Switch), as does another level I can’t recall, exactly… it has a bunch of Monty Moles that explode all at once. I think it’s on Chocolate Island. I think there might be a third with two Sumo Bros. and an Amazing Flying Hammer Bro. onscreen.

This again? Last time this came up, it was calculated that in order to get to the levels (mg/kg body weight) found to affect fertility in study rats and pigs, you’d have to eat something like between 2/3 and 2x your body weight/day, every day (because it’s easily excreted), of chlormequat-contaminated oats. The studies on rats and pigs used much higher concentrations than are found in oats.

The notch is what it is: a compromise between webcam quality, branding, and thin bezels. But it’s hard to argue but that Apple’s software integration with it is mediocre at best. None of the extra space is usable except by anything but the awkwardly tall menu bar and the status items or menu extras it holds, and the system not being aware of the notch —sometimes— like letting status items pile up underneath, or being able to put the mouse pointer underneath it but not when a mouse button is held down (this behavior was removed in a late version of Ventura), or putting the picture-in-picture window partially underneath the menu bar (like it expects only a regular-sized menu bar to be there)… is symptomatic of a larger quality and integration problem at Apple, I think.

Escape Velocity. Take that Cap’n Hector!

icodestuff · 2 years ago

EV: Nova was the first shareware game I ever paid for. Also how I learned to use ResEdit. The Ship Variants mod was the best! There was nothing quite so overpowered as a Type IV Modified Valkyrie, a ship that was basically impossible to capture in stock without a massively larger ship or small fleet. It had most of the cargo capacity of a stock (Type I) Mod. Valkyrie, but about 3-4x the weapons mass, filled with missile launches and an ion beam (unheard of on a 2-day jump ship), and with room to spare for a medium laser.

I say this as someone who grew up in a small rural area and now lives in a slightly-less-small suburban/rural mix (but not in Canada). All this does is overfund rural areas and underfund urban areas which are likely already underfunded - although my only experience is the US so maybe Canada is a little better about this.

Rural areas do not "have no voice" - they have exactly the representative power of their population, the same as urban centers. I'm not sure what makes people in or from rural areas thinks that once people live close together their voice should count for less. How is it "right" or "fair" to move to an urban center, take advantage of urban amenities and services, take advantage of that higher salary, and siphon some of that tax money away to rural areas because of nostalgia?

More, even, since ridings don’t all have to have the same population, unlike Congressional districts.

They don’t mention falling life expectancies. If people are dying before they use as much care as expected, small wonder costs would rise less.
