For anyone else who was also seeing just garbled characters in the title, and since the first few paragraphs of the linked article don't explain what that is:

GF2P8AFFINEQB is one of the AVX-512 CPU instructions that performs an affine transformation (essentially AX+b) on a Galois field - finite number fields used in coding theory and cryptography.

> Bilinguals and monolinguals remembered English competitor words that overlapped phonologically with a spoken English target better than control objects without name overlap. High Spanish proficiency also enhanced memory for Spanish competitors that overlapped across languages. We conclude that linguistic diversity partly accounts for differences in higher cognitive functions...

This conclusion sounds like quite the leap.

Even if the two observations they generated turned out to be 100% ironclad true, generalizing to "speakers of different languages" as a title and "linguistic diversity" from observing just two languages seems like a big jump.

> ... we had to build our own physics algorithm for very specific problems, and ended up selling the software ...

Like a simulation algorithm? Can you elaborate on what kind of algo and the problem it solved?

Unrelated, but this style he draws the timelines in: is it hand-written/hand-drawn, or software-generated?

It certainly has the overall feel and appeal of being done by hand, but I'm not sure.

If it's software, does anyone know which software, what's the name of this style, etc?

Uber gets to introduce driverless cars finally (an old promise of theirs) without the costs of owning or developing hardware, and use that as leverage over drivers.

I don't think Uber has anything to fear from Waymo:

(1) It will take years for Waymo to ramp up to "independence" scale. How many cars do they have now, and how many would they need? How long will it take them to negotiate new regulations with every city and state? 5 years?

(2) This deal is probably not exclusive. Uber can strike a similar deal with Cruise as well. Uber becomes the Amazon of driving services, a platform gating access, with all the data.

(3) Having a big money company behind them is good. And if Waymo acquires Uber in 3 years, it's not necessarily a bad thing for Uber.

zodzedzi | 2 years ago | on: Waymo and Uber partner to bring autonomous driving technology to Uber

Many comments saying Waymo could easily spin up an Uber-replacement app are missing one key point: integrating with Uber allows Waymo to have a slow rollout / soft-launch.

They can start adding support one city at a time. And for the Uber user, the Waymo option only pops up for you if the ride you requested is within the Waymo range and they have cars available.

This way they can also collect tons of data about how users respond to the offers, affinity to driverless cars per region, price elasticity, etc. And then dial the supply up or down as they wish. They can even start covering a city with just two cars if they wanted to, and then build popularity and word of mouth.

On the other hand if they started with their own app, the lack of car coverage in most areas (due to low car supply, pending regulations, etc) would quickly frustrate users who would then switch to another app, so user retention would be a nightmare.

Not to mention side-stepping all the customer-facing operations of running such a business, which Alphabet does not have an affinity for.

I don't see any of these options in my plugin. I have NoScript 10, and it looks like there is a NoScript 11 out there; is that what you have? Maybe the feature was introduced in 11 and I'm missing that update; checking their changelog now...

Edit: Correction - I do have NoScript 11; but don't see those options.

I see "Custom" allowing you to choose which elements (frame, fonts, etc.) to allow/block for the domain you're configuring.

But it doesn't offer the ability to say "apply these settings to the domain example.com only when I'm visiting example.com, and not when I'm visiting anotherexample.com which happens to load JS from example.com".

zodzedzi | 3 years ago | on: DuckDuckGo Removes Pirate Sites and YouTube-DL from Its Search Results

I use DDG as my default search engine, along with NoScript in the browser. Often when I visit a new website, I peruse the (long) list of domains that the site is trying to pull javascripts from.

I keep most of those source sites in UNTRUSTED status (including some of the big names in search/ads/etc). But I've always had DDG in the TRUSTED category because I had only seen its javascript before on the main DDG website.

(Unfortunately NoScript has a limitation that you can't tell it to "only TRUST javascript from example.com when I'm visiting example.com").

But recently I started noticing some websites pulling javascript from DDG (I don't remember which sites).

So now I was wondering if DDG is getting into the tracking business, since they're now having their javascripts load from third party sites.

Obviously this is anecdotal. But does anyone know if they are indeed beginning to track?
