>This thing is Pontiac Aztec bad.

Is it just me, or DDG really shows an image of a turd when searching for "Pontiac Aztec"? :D


same for me lmao


Parent meant that it can't obscure the environment. E.g. you can't put your finger behind the cover of the compass in your image.


You would need a beefy machine to render 45 8k images per frame.


This is 45 image segments encoded into a single 8k signal. I have a smaller one, and it's amazing, but its 4k image input results in approximately 800x600 equivalent for each rendered angle.


So now everyone's pet project gets a language extension in Swift? Apple extended the language with @_functionBuilder for SwiftUI. Now Google wants to extend it with this differentiable stuff for TensorFlow.

Why won't they implement proper metaprogramming support instead of proliferating the core language?

Proper metaprogramming support is hard. Polluting the language with special case hocus pocus is relatively easy.


> Polluting the language with special case hocus pocus is relatively easy

or if it's well done is it still hocus pocus pollution?


Then it's pollution with compiler magic. But only if it's really well done.


Because you don't want to be the one whose team is lacking in agility on the next company all-hands meeting ;)


I prefer this one:

Where the Laplace Transform comes from (Arthur Mattuck, MIT) https://www.youtube.com/watch?v=hqOboV2jgVo


A piece of jewel. Reminds me of chalk board talks of Gilbert Strang and Robert Gallager (also on youtube, mit video lectures) that celebrates this gift for teaching us something.


So, you'd like to expose the whole kernel to Spectre-type attacks. Wonderful!


Well, for trusted code that doesn't expose any mechanism to run foreign code (ie browsers), spectre is largely a non-issue.

So the trusted core part of the OS can run without any spectre prevention, though you can still enable the various hardware protections available in the chicken bits.

And if it's necessary to protect against spectre attacks, you can use shim layers or even isolation into ring3 to take preventative measures. This allows leveraging performance were important and security where necessary.

If it's in webassembly, you can even run two versions of a driver; one with spectre-mitigations compiled in and one without, sharing one memory space and the kernel can choose to invoke either one depending on the call chain.


Trusted code has to be free from vulnerabilities to be immune, so it's still an issue even for trusted code. And I'm pretty sure neither webassembly nor other sandboxing methods can fully mitigate speculative attacks on out-of-order CPUs within the same address space, you'd need a programming language with a compiler designed from scratch for it.


Well, it doesn't have to be free from vulnerabilities, not any more than any other OS code. The sandboxed code that is running trusted (ie without trampolines and spectre-defenses) would still hold the guarantees given by the sandbox (WASM), which are pretty much on par with what a modern browser can do for JS and WASM. And keep in mind that both WASM and JS now have spectre-defenses, so there is no need for a PL from scratch for this.


> And keep in mind that both WASM and JS now have spectre-defenses, so there is no need for a PL from scratch for this.

As far as I remember they weren't able to defend from side channel attacks within the same process completely and decided to rely on process isolation instead, estimating it would be too much work to address all known spectre class vulnerabilities on their existing compilers and too hard to ensure for defenses not to be broken later by compiler developers.


Sounds like gentrification to me.


It is, I live in the Red Light District for 34 years and have seen it all. This plan to get rid of the girls is a setup of the civil cervants and the church since around 2000. When I came living there in 1985 the neighborhood was rough, relative unsave because of dealers and junkies and there was a lot of crappy state housing. Round 2000 most of these problems were gone and the land/housing slowly started to become more valueable. A lot of parties with interest to gain a lot from that neighbourhood, with all their own reasons, started to plan for the removal of coffeeshops and the girls. The tourists coming for these coffeeshops were low key and hardly a problem for the authorities. The interested parties started 1012 project to buy out all the owners of the window bordellos, this failed due to finance problems caused by the expensive north/south metroline and the downfall of the economy in 2008. Then the parties had another plan, "Let's invite lower class uncivil drinking tourists through the tourist buro", then they can trash the neibourhood and make life difficult for the ladies behind the windows. Then the parties started to talk how little respect and danger these girls are getting from those tourists, now we have a reason to relocate these girls and make the money from those now high valued buildings and land. There are billions involved with this, don't let people fool you into thinking that there is a milligram of altruism.


Why not have carrier executives install 5G base stations on their houses as a publicity stunt?


Sanctions aside, Iranian pistachios taste so much better.


TFA states:

"In Iran, more than 50 varieties are cultivated, not counting the great number of wild pistachios. But even today, the vast majority of California’s pistachio trees are Kerman."

would be interesting if local producers got into this. given the prevalence of boutique tomatoes and the like, I could see this working.


how far off from Turkish pistachios are they? I can get those through nuts.com and a few other places and they are certainly different from what we encounter in the super market.


Pretty far. Iranian pistachios are identical to Californian pistachios, just red in color. Commenter above probably is influenced by the red dye and in a blind taste would fail to distinguish between the two. Turkish/Armenian pistachios on the other hand are smaller, more elongated and if salted typically are packaged with coarser salt. I prefer the latter, although they can be more pain to peel.


How do you source/buy these different kinds? I've mostly had Californian pistachios, and I think they're amazing. But I keep hearing about the Iranian/Turkish varieties which is probably where the pistachio plant is native to.
