Dewer! thanks, I knew there was an actual name for those heavy duty thermoses but it completely escaped me :D

The bigger issue is that helium is a functionally finite resource, and does not remain in the atmosphere (at least IIRC it literally just floats up until it gets blown into space). The bigger local issue you run into with liquid helium and

Ah, you’re concerned about person using js to execute the side channel portion of the attack, not the bit creating the side channel :)

Yeah, there was a paper about AI excellence in diagnosing radiology images a few (5-10 now?) years ago, that turned out to be largely driven by accuracy skewed bias in the input data (IIRC it was using the existence of lab-style lighting, r

In your proposed scheme of URL->hash, everyone is expected to pay a big service to host their data, so that their page is accessible to that service's users? Or what? It sounds like you're saying "use IPFS for web hosting&

No, the paper targets "constant time" operations, not timing agnostic. The paper even mentions that blinding works, and that to me is the canonical "separate the time and power use of the operation from the key material"

why do we even need caches? why do we need prefetchers? But in answer to your bullshit backdoor conspiracy theory (JFC processors have caches and timing variants because people want fast CPUs, you cannot have constant time and fast, apple i

Happily there are mechanisms to do just that, specifically for the purpose of implementing cryptography (I commented at the top level and don't want to just spamming the url).

Because JS/html provides APIs to perform cryptography(I can't recall whether the cryptography specs are part of ES or HTML/DOM) - if you try to implement constant time cryptography in JS you will run into a world of hurt due

If you're writing cryptographic routines you should either use the platform cryptography libraries, or follow the documentation: https://developer.apple.com/documentation/xcode/writing-arm6...

I personally think APL is wonderful simply because of the original APL specific keyboard [1] I've looked briefly at R and found the syntax and semantics to be less than stellar. Obviously there's going to be some bias in that sent

Last time I tried gnome it was in an Ubuntu install I think which had a weird launcher that imo didn’t work particularly well. I’m not sure what you are meaning by a launcher here - to me there’s a fairly reasonable ambiguity about what is

optional consumer goods may be cheaper. Necessary consumer goods are not. A cynic would say companies selling necessary goods have realized that they can price gouge because people don’t have a choice about paying, and then claim inflatio

string_view doesn't guarantee life time of the backing buffer either. It's a fundamentally memory unsafe type.

That and of course every implementation of austerity seems to do long term damage to the economy of countries that apply it. I recall a few articles even saying that the maths that supported austerity was the result of a spreadsheet error,

Have compilers (or I guess x86?) gotten better at dealing with the frame pointer? Or are we just saying that taking a significant perf hit is acceptable if it lets you find other tiny perf problems? Because I recall -fomit-frame-pointer bei

Which is absurd when you think that the internet used to be usable on 14.4k modems. I remember having to plan to take up hours of time on our phone line to download giant files that were smaller than many basic webpages these days (ignoring

It’s not just slow devices, it’s also any time you have any kind of weak connectivity. I think every OS now has tools to let you simulate shitty network performance these days so it’s inexcusable that so many sites and even native apps fail

It depends on exactly what is being done. A fairly common idiom is to use memory protection to provide zero cost access checks, as you can generally catch the signals produced by most memory faults, and then work out where things went wrong

A gross and low performance option for now might be to run Java under Rosetta, but I’m saying that based on them saying that this is apple silicon specifically and processes under rosetta have a bunch of quirks to support intel semantics. T

Well no, you still have to pay taxes on the stock when it vests, usually stock compensation is handled by a fraction of the stock being sold upon vesting to cover those taxes but I'm not sure how that works when you can't sell t

It's wage theft, because the law says you owe employees minimum wages by law, and if you aren't paying them that amount, you're stealing the excess from your employees. The fact that you think you should be allowed to pay peo

At some point though we do need to get people to stop just doing shit because a post on Facebook tells them to. Sure impersonating someone to defraud people should be a crime, but also the fact that people think "random page on Faceboo
