There are actually a few decent choices for eye tracking now (a company that was just acquired by Bytedance had a pretty good eye-tracking standalone), and there are a few crazy headsets that do all of your listed requirements for 1. and more, but they're all in the $1,000+ range.

Lighter-weight headsets is something necessary but also something that is in sort of a weird spot. The Quest 2 is actually a lot heavier than average, because it's standalone. As cool as it is, it's regressive in some interesting ways.

For better displays, there's already some pretty impressive displays these days if you don't mind jumping up in price a few notches. Enthusiast-range, for sure, but still consumer models.
This is wrong : what google currently does on firefox is make you go through a link that logs you clicked on it, then redirects you to your destination.
This doesn't need any javascript, it just needs to log your http request, so it should work on any browser (even, say, elinks)

None of the arguments about battery life, security, or privacy were contradicted in this article.

Additionally, the author seems to be under the belief that "if only Safari supported PWAs, they'd be as good as native apps." But that's an exercise in wishful thinking. There's no evidence that that is true, nor has there ever been.

Finally, "write once, run anywhere" has been a dream since the early days of Java and applets. It's never come true, and there's nothing significantly different today about computers that makes it any likelier.

I don't know about y'all, but I have no desire to run a lowest-common-denominator webapp on my iPhone. I paid a premium price for the thing and I want a premium experience from my software.

(I'm still open to the argument that PWAs are a necessity, as opposed to merely a "nice to have," and from a developer who has a track record of publishing high-quality, irresistible apps that customers love.)
The approximate kNN is quite nice for many use cases, and scales to billions of documents. However, you're correct that filtering happens on the results. This is only an issue in certain use cases where filtering is very narrow, as you can often just request much higher k than the number of results you really need without much slowdown.

If the filtering is very narrow, as you commented they also provide functionality to perform pre-filtering and then exact kNN on the results. This is of course higher latency, but still quite acceptable for many use cases (this is how I use it).

I believe there are use cases that Pinecone addresses better than Opensearch, but I want to let people know that there is a free, open-source solution which _may_ also work for their use case.

Elasticsearch does currently support vector search through script score using dense vector fields, however I suspect they are still working on improving it and I prefer the Opensearch implementation for the time being https://www.elastic.co/guide/en/elasticsearch/reference/curr...
The writing reminds me of a 2600 article. I miss those days. Super cool though! I'll pick one up, eventually :)
Had you read the material I posted,

"In 1974, RCMP Security Service Corporal Robert Samson was arrested at a hospital after a failed bombing - the bomb exploded while in his hands, causing him to lose some fingers and tearing his eardrums - at the house of Sam Steinberg, founder of Steinberg Foods in Montreal. While this bombing was not sanctioned by the RCMP, at trial he announced that he had done "much worse" on behalf of the RCMP, and admitted he had been involved in the APLQ break-in."
It took me a while to realize this but all the successful tenured faculty members telling me to become a professor was an extreme survivorship bias. I don't tell anyone to be a professor.
I think a lot of tech companies meet the fate where they get diminishing returns on growth and have to keep hiring and spending a lot of cash to chase smaller and smaller gains. Bandwidth is expensive but having thousands of highly compensated employees is also very expensive, probably more so.
Humans aren't built to work late. There's a whole host of physical health issues and mental health issues that comes with working a large number of hours.

The prey that a human is trying to hunt isn't gonna be up after sundown. Ancient humans can't hunt or forage or farm things late into the night.
Any significant improvement will necessarily be a significant change and therefore alien.

Computers were alien, and the culture projected all its fears onto them: rightists churned out endless movies about slave revolts with computers and robots in the role of slaves, while leftists tried to bomb and burn down computer centers as oppressive instruments of the System.

FORTRAN and COBOL were alien to experienced programmers, who seriously doubted how optimal the output assembly would be.

VisiCalc was alien to Fortran programmers. You're still pushing back against the remnants of that rejection today.

MacOS in 01984 was alien to those of us who'd grown up writing BASIC. It provoked hostility, too!

Pascal was alien to me because it didn't have line numbers.

Online chatting was alien. We called ourselves "geeks".

I still have anti-JS JS from 02000 on http://canonical.org/~kragen/hotlist.html because JS was alien and I hated it.

When we pioneered AJAX and Comet later that year at KnowNow (one of three independent inventions), it was alien, and in fact it took four years before Gmail took AJAX mainstream; Comet took even longer.

So don't worry about being alien. You're shooting for a revolutionary change, not an incremental improvement. Revolutionary changes are difficult under the best of circumstances, but they are impossible to achieve without being alien. Your weirdness budget isn't unlimited but it's necessarily larger than for an incremental change.

I know it would be a headache to achieve it, but it would be pretty useful to have an open-source runnable version of any of the older Subtext prototypes.
I agree that Western companies operating in China are chasing a phantom carrot that the CCP will never allow them to catch, and that reciprocity, or "equalization" as I think of it, is necessary in trade.

If Western companies can only operate in China via 50/50 partnership and technology transfer requirements, then the same should apply to Chinese companies in the West.

If Western social media companies are banned in China, then Chinese social media companies should have whatever restrictions are constitutionally possible in the West, with a caveat [1].

Etc.

That said, I think Western governments need to realize that their Chinese citizens are going to be put under pressure by the CCP as you said, but to presume innocence and err on the side of protecting them.

The CCP will use both carrot and stick to coerce ethnic Chinese back to China, or to enlist them in espionage operations. Western governments need to develop strategies to counter that, to ensure their Chinese citizens remain safe and welcomed in their adopted homelands, and that they can safely reject CCP coercion and be protected by their adopted homelands' governments [2].

Some spies and agents will of course slip through the cracks, but Western governments can deal with those as they happen. Better to protect the majority of innocent Chinese who emigrated to the West for a better life, than to implicitly criminalize them all. The latter would play right into the CCP's hands.

[1]: The 1st Ammendment may make banning social media companies impossible. It's also possible that allowing Chinese social media companies in the West is still a net gain for spreading the ideals of free speech and anti-censorship.

I sure hope one day you're my competition.
You're testing for the characteristics of your function - inputs and their outputs. If your function takes strings, there's a well known set of strings that are typically known to cause issues. It's the same for every data type. And for every operation against/between those data types, there's a known set of issues.

You can be pretty certain of a function's correctness (or more accurately, the correctness of a refactor - what unit tests are most useful at, in my opinion) without having to re-write the function in a slightly different way.

But to get back to the topic at hand - code coverage is a pretty bad measure of program correctness. What I was really trying to show is how bad code coverage is at predicting correctness for even the shortest and simplest of functions.
I just want ublock origin on iOS.

I bought an iPhone after seeing that it had Firefox, but I should have done more research. It's not actually Firefox, just a rebranded WebKit. It doesn't support extensions.

So, after trying a few paid Safari "content blockers" and being dissatisfied, I gave the iPhone away.

How is this a different situation from the antitrust case which prevented Microsoft from bundling Internet Explorer and preventing competing browsers in Windows?
I like to speculate for reasons this might or might not make sense at several levels, although mostly just conjecturing. The fact everything works is very interesting, but it seems so hard to come up with something concrete.

You have a map from some high dimensional vector space ~ k^N -> H, some space of hashes. H sort of looks one dimensional. I assume that actually the interesting geometry of your training data lies on a relatively low dimensional subvariety/subset in k^N, so maybe its not actually that bad? It could be a really twisted and complicated curve.

However you still need to somehow preserve the relative structure right? Things that are far apart in k^N need to be far apart in H. Seems like you want things to at least approximately be an isometry. Although there are things like space filling curves that might do this for some degree.

Also maybe even though H looks low dimensional, it can actually capture quite a bit (if your data is encoded as a coefficient of a power of 2, you could think of powers of 2 as some sort of basis, so maybe it is also pretty high dimensional).
No, they aren't. The NSA can't just waltz into Apple and break into their HSM to steal their keys. These systems are designed to be robust even against physical access attacks. Even if the NSA had a backdoor in commercial HSMs, they'd have to get to them physically, as these things aren't on the internet directly.

The Snowden leaks gave us a very good idea about what the NSA does. Tap fibre. Backdoor products in transit. Develop and use remote exploits (nothing particularly amazing about them, it's on the same level of RE/exploitation/polishing work as what I've done for game console homebrew in the past). That one time they actually did something novel with modern crypto and figured out how to efficiently break 1024-bit DH for fixed parameter sets. These are all practical, reasonable things that are a far cry from the magical abilities people like to ascribe to them.
Here's my guess either a. Don't like tailwind; or b. Don't like non-plaintext emails
The hybrid F-150 with an onboard generator and all electric F-150 are being positioned for people who need to do serious work, like arc welding, or for whom a mobile power plant is useful.
Compete on what though? Every web developer right now has no choice but to design for Chrome as well. You just don't care because it's what you would have chosen anyway. There's no "competition" in the browser engine space. There's only posturing for market share dominance and lock-in which you can call competition if you like, but nobody is competing based on "may the browser users like best win."
Wouldn't you have to worry about anyone who had strong family ties regardless of birth?

The worst kind of problem in the car business is to have a hit and not be able to produce them. I told some Ford people over a year ago that I questioned the company's commitment to EV's. They asked why and I said that because they have no plans to build their own batteries.

They have a hit with the Mustang EV with some dealers asking $20,000 over list for them ;<(. They will have even more success with the F-150 EV.

Presently they can't produce near enough of them because of the chip shortage. But if that wasn't a limitation then batteries would be. Must be they've figured that out ;<).

Meh, comparing to the 90s peak in absolute numbers makes no sense, and seems disingenuous. 21000 murders now vs 25000 in the 90s is still half, per capita, there are about a hundred million more people here now.

Sounds almost like an argument against 3rd party apps on Apple's platform overall. Browsers are just one specific type of 3rd party app.
Nope, that's not what they were saying. They did say that they'd eventually cut out the store for people on legacy Oculus accounts, but your headset would still be perfectly usable; you'd still be able to load .apks in like you can now, you'd still be able to use it with a computer, and it would still more or less work just fine, as long as you weren't depending on Oculus functionality beforehand.

It'd be more like a Wii without Nintendo Wi-Fi Connection. It really won't be that different unless you're dependent on their online services.

However, eventually they'll be getting rid of the avenues to make a new account without a Facebook account like they've already slowly been doing. Which is a bad move, but while the avenues are available they might as well be taken.
Memphis has slowly bled jobs for the past 60+ years, and we’ve been darn close to bleeding out since 2008. We’ve routinely lost corporate jobs to other headquarter cities, we’ve had outright corporate theft from the city including Delta Airlines stealing Northwest Airlines, lying to Congress under oath by saying the merger would not hurt competition and they wouldn’t close the hub (it did, they did).

Not to say that Memphis “deserves” jobs, but other cities seem to get the government jobs handouts (namely, military or 3 letter mega-orgs), the big corporate “insider deals” due to better politicians and connections, and Memphis has been shut out de facto. The case for Memphis is just a phenomenal location within the US, excellent freights access via interstates, rail, FedEx super hub, and river, low cost of energy, cheap land and cheap labor. You would think this would mean something for corps looking to do business, but it’s been crickets.

This is tremendous news for the region.

Certainly, Apple's crippling of PWAs and total control of browsers on their platform is a problem, but I've seen enough to know that what (web) devs really want is Chrome (or, more accurately, a monoculture). Whether it's Chromium in a browser (Chrome, Edge, Opera) or Chromium in an app shell (Electron), your stack is never good enough unless it's Chrome. Hopefully both Apple and Google have their worst aspects reined in at approximately the same time because otherwise we're just going to move the problem to the web layer.
Disagree, F150 is more for fleet, labor, handyman, "serious" work.

The cybertruck looks cool, but it lacks many features that are needed for daily usage for an actual laborer/worker.

Not at all bad, but working on the field, the cybertruck already falls short to Ford in many aspects.

Note that according to the story, the fake email address was provided by the CEO, which was then used to arrange a call between Goldman and the COO/cofounder, pretending to be a YouTube exec.

At first glance, that seems to implicate both the CEO and the COO/cofounder in the fraud. Even if you buy the story that the COO was experiencing a mental break, I wonder what the CEO's excuse was? Must be pretty good, since his board apparently was fine with it...somehow.

(One rather suspects the FBI and the SEC will be less impressed.)
For me, the problem is I wear glasses and I have no interest in switching to contact lenses. I’ve never found a car headset that worked with glasses well
And of course the PC demoscene legends Future Crew did Epic Pinball in 1993, so there's definitely some kind of fixation on pinball by demosceners!

Not that that's a bad thing by any means.
Yep, according to the FAQ [1]:

> Quest 2 requires everyone to use a Facebook account to log in.

> If you are an existing Oculus user and have an Oculus account, you will have the option to log in with your Oculus account and merge your Facebook and Oculus accounts.

I can't speak how enforced these are, but even if it's a soft requirement for now, it's enough for me to avoid it. Pity, since it seems pretty good tech wise.

A decade ago, Java was derided for letting developers ship apps on multiple platforms while forgoing native controls, with a high memory and storage footprint with the JRE through the JVM. While JavaScript is not Java, it has essentially become Java: instead of shipping a JRE and Jars, it’s the entirety of Chromium, with its JS VM, and a relatively high memory and storage footprint.

It seems to me like we haven’t changed much here, resource wise.

Then, particularly on mobile devices, many apps recreate native controls with weird quirks or defects that don’t play nicely with the native conventions. Just like in the Java world, you can get “almost perfect” but if the OS updates or a convention changes, the non-native apps are stuck reinventing the wheel to accommodate change (or they ignore it entirely).

As a developer, I love writing the same app for multiple places. As a user, I find it infuriating to deal with. While Apple is assuredly being lame by preventing other browser engines (I want Firefox, with WebRequest in blocking mode), they’re not wrong if they think that more PWAs will bring problems.
Yes. Storage also. You can get >99% ordering quality of exhaustive cosine with a tiny fraction of memory usage
> Also my personal style is to do shit ton of refactoring. This means I usually start with something that only vaguely resembles the end result. I spend a lot of time moving stuff around until I get rid of everything that I don't like.

Same here.

I do think there's value in some unit testing: mostly for small units whose behavior is a bit tricky to verify by just looking at the code or running the application. These are usually functions with tricky mathematical expressions, or something like that.
My uncle works for nintendo, this is legit.
The US government did round people up, torture them, and put them in concentration camps. How do you think the WHOLE country was built? We living in this country benefited and are CONTINUING to benefit from it.

Ever hear of the Indian reservation system? The US government rounded people up, took their land, and forced them into concentration camps. If they left the reservation, they were hunted by the US cavalry.

It is so rich to conquer a people and then show remorse while continuing to occupy the land.

How would you compare that part of American history to the Nazis? Or how about comparing that to the Japanese in WW2? Is the US really any better?

I haven't used one of those, but I can guess what he means based on owning an Oculus Rift 2. Let's say I want to start playing a Steam game with my headset. To do so, I must install the Oculus software, sign in with my Facebook account (it's a brick with a headstrap without an account), then find the setting that enables "non-Oculus software" to operate the Rift display. Using the Rift always starts the Oculus software. There are shortcuts on the headset that throw you into Oculus's own environment for buying and launching games.
Ford should be making the plants in Michigan where it's based. They've shut down so many factories there over the last 30 years...
Browser specs are actually pretty well communicated. Most stuff get buy in from major players in the game (e.g. Google and Mozilla). Some stuff remain specific to one browser (e.g. idle detection in Chrome).

Apple is the one that has consistently been either extremely behind on new functionality, or just broken implementation of existing functionality (basic auth on mobile safari comes to mind).

And again, my main issue is that there is no way to test on Safari without owning Apple hardware.

I haven't looked into it for other devices, but it is technically possible with the Quest to get custom lenses for the Quest. Not from FB, but other companies have filled this space.

I've gotten rid of my unit, but back when I had it, custom lenses were the best thing I did for comfort. I can't wear glasses close to my eyes, and was just generally miserable with the glasses squished in an already small space. The custom lenses solved all of that.
