In resting-state and task fmri it is common to regress out BOLD time series of white matter as a nuisance covariate; the rationale being that whatever is causing BOLD fluctuation in white matter voxels it does not reflect neural activity within the voxel;

nevertheless white matter does appear to exhibit BOLD responses that aren't merely physiological but arr related to task based cognition.

I am willing to entertain the idea that white matter bold is important to study, but wanted a mechanism to explain why its relevant, and not mere epiphenomenon or spatially-temporally lagged response to neural activity elsewhere.

Ask HN: Which companies are used to verifying shipping addresses?
Which companies do ecommerce and other companies use to validate whether a given address exists?

I'm asking out of personal interest, because my address fails to validate on probably 3 out of 10 ecommerce sites, and I need to contact support to get it manually validated. I live in an area where USPS doesn't deliver to the houses, we're required to have PO boxes, and this means that address validation systems based on the USPS database don't work. If the address is accepted, it works fine, and our local post office has a trick where we include a number so that it gets routed to the right PO Box. Amazon handles it excellently and
Amazon deliveries always succeed, though smaller ecommerce ones often fail validation (but always succeed after shipment).

I'm not that interested in self-promotion here as I am in getting more activity on Rust graphics development. I think the Rust core graphics ecosystem needs about five good graphics people for a year to get unstuck.
Rust is a good language for this sort of thing, but you've got to have reliable heavy machinery down in the graphics engine room.

Until that exists, nobody can bet a project with a schedule and a budget on Rust. The only successful commercial high-detail game title I know of that uses Rust is a sailing race simulator. They simply linked directly to "good old DX11" (Microsoft Direct-X 11) and wrote the game logic in Rust. Bypassed Rust's own 3D ecosystems completely.
You’re on it now.

The herbie project using egraphs to explore different ways of rewriting floating point expressions. https://herbie.uwplse.org/ One can also write custom rulesets in egglog (a new egraph rewriting system / language / datalog) https://egraphs-good.github.io/egglog/?example=herbie

The approach is not yet anywhere near being able to touch all the domains sympy can handle. Destructive term rewriting tends to be a bit more forgiving to unsoundness in the rules and still returning roughly meaningful results. EGraph rewriting (and other automated reasoning systems) tend to just return junk as soon as you aren't careful about your semantics. Associativity and commutativity are ubiquitous in CAS applications and encoding these concepts in general purpose terms is rather unsatisfying. The post above emphasizes specialty methods for polynomials, which it would be desirable to find a clean way to integrate into egraph techniques. Variable binding (which is treated in a rather mangled form in CAS systems) is seemingly important for treating summation, differentiation, and integration correctly. The status of doing variable binding efficiently and correctly in egraphs is also unclear imo.

ChatGPT is transitioning from Peak of Inflated Expectations to the Trough of Disillusionment. This is normal. The Slope of Enlightenment is all about getting over the hype and discovering what the technology, in this case ChatGPT, is really useful for.

All new technologies go through this hype cycle. ChatGPT is no exception.

Yes parsers are already sandboxed, and violating the sandbox boundary is where the actual valuable exploit is. Parser vulns are near worthless without the rest of the chain building on it, and the millions of man-years it would take to re-write every last one of them as "provably correct" is better spent hardening sandbox and privilege boundaries.

Which is a completely different problem than simply rewriting things in a safe language.
This is doing drugs, essentially. It so happens we have a dopamine production center attached to the reproduction behavior, and we've figured that mere thoughts about reproduction trigger a dopamine injection just as well. Wasn't there an experiment with mice where they kept pushing the button attached to a wire that made them release dopamine, and they kept pushing it until their dopamine production broke down, they lost interest in doing anything, and died?

This could be implemented without any vendor keys. You associate the user's own key with the user's account.

> Attestation keys are usually per-device, so if indeed only one device gets compromised at great attacker expense, it's usually possible for a scheme to recover.

That's assuming it matters at that point. The attacker doesn't care if you revoke the keys after they steal your money.

And once they extract a key from one device, they have a known working procedure to get more. For non-software extraction most of the expense is the equipment which they'd still have from the first one.

> If all devices just systematically leak their keys as has certainly happened in the past, that won't help, of course.

And is likely to happen in the future, so any design that makes the assumption that it will not happen is clearly flawed.
America doesn't have the manufacturing base it had in WWII. Then, it took months or even years to ramp up the existing manufacturing to wartime capacity. Now a lot of America's manufacturing has been outsourced to China and other far eastern/southern Asian countries.

I was reading about the terms "vaccine" and "vaccination" and learned what a vaccine really is. I used to think of injections and syringes when I would hear of vaccination.

According to wikipedia,
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. [1]

Does that mean a vaccine can also be administered in forms other than an injection such as an oral tablet?

Then the already-fractured rocks are used (forever?) to absorb CO2, heat to release, and repeat. (Do they somehow lose that capacity over time?)

But also this seems to be assuming that all the energy comes from renewables in the first place, including the energy for crushing the rocks...
Why would discharge rate be important? I'm assuming discharge rate as in "ability to deliver high current" here. If you install capacities to serve more than a few minutes or hours, even the weakest batteries won't be challenged by grid peaks.

If you mean self-discharge, and the importance of that being low, yeah, that might become a factor to keep an eye on once we reach capacities to solve seasonal cycles. But even then it's nothing more than another element in what makes up the total charge/discharge efficiency.

We did create transmission of diseases across the planet by sending explorers between continents. The same way we enabled COVID spread through international travel.

As far as taking them continuously, there are many chronic conditions that people take medication for life to resolve. For example high blood pressure, they put you on medication and its expected you will be on it for life, it isn't always solvable by any other means. Many other examples of chronic conditions which means ongoing medication must be taken.

What I think will be interesting is the higher order impacts to the major food companies. If enough people are on medication to disrupt the desire to eat sweets and highly processed foods, the incentive for the food companies is to try to find a way to bypass the effects of the medication.
> I would call it a social necessity which makes it very ethical as long as it is truthful.

Disagree on this one. Blogs, media, social, word of mouth, etc. would still exist without advertising and would serve the purpose of all of those things. PR teams would become as large as marketing teams, things would get exploited (they already are), but we wouldn't be subjected to distraction and manipulation.

I don't think ads are the most evil thing there is, but society would be fine without them and you would probably see a much smaller imbalance of power in wealth and companies. I'll take 1000s of small forums compared to one big Meta.
Everything I said is 100% true. There are a lot of people on this very site working in adtech who don't feel like they're doing anything wrong at all and use the exact same logic that people use to justify "telemetry". In their mind, they're making a better product and a wealthier, more productive world in the process.

Do their vendors, or your DSP, even have the information of where user profile data originally came from? If it was exchanged on multiple data brokers and part of 2nd or 3rd party data, is the original source even known? And if so, does your platform give advertisers the filters to exclude profile data based on method of acquisition?

And you're saying that all of those big brands refuse to use profile data acquired by fingerprinting, even if it would allow them to microtarget their campaigns? So they're essentially valuing people's privacy over their own profits? Somehow I highly doubt that.

I'm not saying that what you're saying is false. I just think that in an industry with highly shady and consumer hostile practices, built on the core ideas of psychological manipulation, that needs to be regulated to stop violating people's right to privacy, and even then finds ways to tip toe around regulations, it's quite unbelievable that all of a sudden they have a change of heart and actually claim to care about consumers. I mean, you're a part of it, so forgive me if I instinctively distrust your claims, and the claims of your clients.

> Literally all of them want privacy focused advertising

So they're running ad campaigns without targeting user profiles at all, in the same way advertising is done on traditional media? Because that's the only "privacy focused advertising". I highly doubt this as well.

Again, privacy and advertising are part of a zero-sum game. Advertising profits increase at the expense of user privacy, and the more targeted campaigns are, the more profitable they are. It would be foolish to think advertisers and adtech companies would be willing to sacrifice their profits out of the goodness of their hearts. This is why we need regulation in the first place, because they're not capable of self-regulation, and will pursue profits at all costs. But this is nothing new, and big business has been exploiting people since the dawn of industry. So please don't try to frame advertisers and adtech as some kind of benevolent actor.

Not a great take. The TPM provides the primitive of "non-extractable keys"; it's not supposed to magic up secure boot.

Even then, the argument that a TPM is worthless because it can't guarantee that software is free of vulnerabilities just belies an un-seriousness of the post. Like okay, that argument applies to every threat model ever.

A boot chain can be secure with or without a TPM. The TPM just says "I'll record what your boot chain told me and spit it back out with a signature that is verifiable by public key cryptography, so that you can tell it's what your boot chain told me. How much you trust your boot chain is up to you."
