The most obvious explanation is that the American defense department is probing Chinese and Russian military with advanced drone technology and they would like the Chinese and Russians to think that the American military is also being probed and are equally baffled by it. PsyOps in other words. I doubt they are buying it. I assume that when the Chinese or Russians encounter any unexplained tech it is assumed to be the American military given our vast expenditures on military tech and our track record of high tech accomplishments.
Ask HN: Why won't Apple and Google take down Ponzi schemes off their app stores?
This app (KWAI) has all the hallmarks of a Ponzi disguised as social network.
Users pay for the app and earn money for every new user who signs up to the app using their referal code. It has done a few rounds around the world and it's now growing in popularity in Latin America - there are several twitter accounts with multi-million followers asking their followers to sign up with their referal code and promissing cash returns.

The comments immediately go in to decrying anonymity. This seems precisely backwards to me: Yes, even some mentally ill persons will be less hesitant to behave abusively under their legal name. But many will not, the examples given are people who are behaving abusively in part because they've adopted the abusive conduct as an identity. They aren't ashamed of it.

Worse, a lot of the damage these people can do depends on knowing their target's identity. If some internet nutbar gets overheated in an argument and starts slandering you with random accusations but you're only known as a pseudonym then at worst you can abandon the pseudonym. But you probably don't even have to go that far: without knowing more about you its hard to make accusations that are even credible enough for an internet hate mob.
There are still cases where it’s not E2E, such as when a user is dialed in via a phone call.
I'm writing an article about it, hopefully I'll post it by next month. What got me started was that when I left my job, I had a hard time explaining how the AI part of the product works. We automated customer service for large e-commerces. I wrote a simple yet buggy neural network in JavaScript and it got me excited. I immediately jumped to building a smart device where I can say "Hey Jaziel" (merged name of my kids) and it can perform a command. My JavaScript model failed.

So I turned to coursera, took the deep learning specialization course by Andrew Ng. In a month, I had a working prototype. Sorry I haven't published it yet, but it will also be posted here. Hopefully it makes it to the front page.

> Who needs timer ICs when you have a busywait while loop checking the high res timer...

A lot of people are concerned about power usage these days, particularly if these things are running off a solar cell.

And these days, most embedded controllers include some kind of timer anyway. Micropython has a timer interface that interrupts into a python subroutine. I use this for application level routines interfacing with a hardware watchdog.
Arrow's impossibility theorem does not apply to STAR voting. STAR voting is strictly more expressive than Ordinal Voting systems (i.e. RCV), while simultaneously being simpler to implement (and explain/understand). STAR voting also provides other benefits over RCV, such as being district summarizable.
In my city we have this issue with the screens in the subway trains. There are two screens,

>I imagine that the gearing in the meter had some mechanism to prevent a simple 'rewind' attack.

Big Clive details one of the attacks on older (UK) meters here: https://www.youtube.com/watch?v=gFtB0C0rBaM

It was possible to run them backwards. He mentions possible evidence this would leave behind, and notes (taken from the description):

> Latterly devices to detect this activity were added to meters in the form of non-resettable flags that would move out if the meter ran in the wrong direction, or in the case of digital meters a tamper indicator.
> US based recyclers sell their plastic to companies that then pay to have it shipped elsewhere for reuse.

Is it really for reuse or is it just burning/dumping far from sight? This is a genuine question.
I agree, but where are you getting that number from? They said "group chats", not "massive group chats". I would certainly want group chats with less than 20 people to be end-to-end encrypted, if it were possible.

I think a decent compromise would be just enabling it by default for private group chats, since it'd be costly and pretty pointless for public ones.

I think what you're getting has truth. For myself, I would generalize what you're saying as any given formula/expression is embedded in some context/environment. If one continues to "step back" or go one meta (or repeatedly so), you'll find that at some point, you, the reader/interpreter, will need to fill in some implicit or unreified context. We could call these things (shared) assumptions or axioms. As you say, if I use a function `f` to form a term in my formula written in first-order logic, the definition of `f` is implied because it is expressed "somewhere else". The question is then "where is that expressed?". Since the definition of `f` is assumed from the point of view (semantics) of first-order logic, the definition of `f` could be interpreted as "variable" at a "higher" level.

Going to your parenthesis point, I agree that it is indicating the scope (i.e., the context/environment), and in that sense, I interpret parenthesis here as a kind of meta function, akin to how macros are "compile-time" functions rather than "run-time" functions.

I think first-order logic and relatedly most (all?) logic programming languages are missing a facility for "reasoning" about terms themselves. The reflexive answer to this is types, but this is largely wielded as a developer tool not as a means of expressing meaning. Adding constraints to logic programming is perhaps some of the way there and has the benefit (hope) that type-like ideas could be expressed compositionally as logical formulas rather than as declarations provided by the language.

My own pursuit of this subject is to see if these "levels", as you hint at, can be traversed and integrated into one logical formula language and notation. This all implies some kind of homoiconic metaprogramming, but easier said than done.
> and correlations with every positive outcome are very high

I explained why in the top-level post. People who were going to get positive outcomes anyway are good at getting into good schools.

> the burden is on you to prove a non-causal link, not me.

This isn’t Reddit - I wouldn’t drop some nonsense about made up “burden of proof” and expect anyone to buy it. It’s also rude to make objections like this when you clearly haven’t either considered the point you’re responding to (of course people who went to college do better in life - think about why that might be, under my model, and refute that if you can) or actually done the research into the presence or absence of a causal link.

There are 30 years of twin studies demonstrating conclusively that education is not an especially strong predictive factor in adult attainment.
Where do you live? Earthworms are not native everywhere and they can be a harmful invasive species if introduced to the wrong place.

If you have a new house, developments are horible, just enough soil to grow grass. You might be stuck buying good compost and soil and tilling that in deep, then letting grass grow for a few years before trying anything more.
Hopefully the prices are at least up-to-date. I oftent skip buying items if their prices aren't listed.
Hear me out: I feel like it’s only now where we have colour bit depth back (after decades of 24bit+8bit alpha when we started with 32bit) and OLEDs with per-pixel light emission that we can for the first time since they were made actually display the pixels as intended, and it’s also the first time we can create pixel art that is a real level up from the old pixel art.

My mind is bursting with 12-bit per channel colours, retina-level bloom created in shaders, with sharp edges where the artist wants them.
You've got this opposite. If aliens were observing us, they would be far more likely to observe our capabilities and military installations than civilian stuff.

You are proposing adding new restrictions on what people can do with their money. That is taking away their freedom. It is worse because you propose it as a solution to problem that doesn't even exist.
Could you please give some guidance on the topic of “what programmers could do for bioscience”? Or point to any resources doing so? Absolutely serious question.
Actually, no. But it's some sort of technical heritage/baggage.
That’s specifically about chemicals presumed for physiological use/purpose, though, no?

Let’s take biology out of the equation. Can we predict chemical structures will give rise to interesting physical properties when you have a large amount of the compound around?

For some examples, could we ever potentially have a formula or model that would allow us to predict:

• whether any other molecules will possess the “infectious amalgamation” effect that gallium has on other metals it touches?

• what chemicals would create a “non-stick” surface like Teflon does?

• what types of chemicals would be both strongly colored in the visible spectrum and also chemically stable, i.e. what chemicals would make especially good pigments?

• whether something will be a room-temperature superconductor?

• whether something would make a better non-reactive glassware than borosilicate glass?

• what types of chemicals will be especially good at being electrolytes?

And I’d especially like to know, whether there’s some property that unites all “chemicals with interesting physical properties” like this, i.e. whether it’d be possible to have a model that tells you that a chemical is likely to have unusual physical properties in some way, despite not being able to predict the specific effect it’ll have.
Sure, but that's why I said compare to other opportunities and repeat. But you are right, I should have said "a better way". EV works ok at the beginning to sanity check, because you have very little info, and honestly unlikey enough to do a utility comparison on two similar offers. EU is really hard to even estimate here.

If you truly value equity at $0, why accept it at all? Fwiw I've seen this experiment done with founding engineers, offer a sliding scale of salary and equity, in bounded ranges. 100% of people in that case (small sample) took some equity in exchange for a bit lower salary. Obviously they didn't actually value it at $0.
>You might as well say "it's pointless to try to understand anything not strictly human".

No that's the opposite of my point. I'm saying that I believe we should try to understand the possible 'them' from a less anthropomorphic perspective.

>I think we are allowed to discuss things from an anthropomorphic lens because thats the only point of reference.

That was pretty much my point in my last paragraph and why I in my original reply said I don't have a better system.
> The state's monopoly on violence should be in the hands of the courts, and not individual officers doling out punishment

I would generally agree, but at the end of the day any state prohibition must eventually be enforced by some level of violence or more mildly, coercive force.

One could write several books about the nonviolent crimes US police have killed people enforcing. And this is my point. The arm of the state must be reigned in somewhere.
> Not sure whether that is the only reason why some games are not on Gog though; often Mac ports are missing too. It seems more like missing rights for the ports than technical reasons.

I don't know; probably not. But this was the response I got back from the devs of "Expeditions: Conquistador" when I asked if they could release the Linux version on GOG (when I bought it originally I still had a Windows machine).
If they didn’t make you, they can’t hurt you.
Scroll to the bottom of the “my account” page for example and you’ll see a list of dozens of wholly owned subsidiaries and websites, many of which were purchases.
How is this any better than looking at the real product on the shelves? I mean, why did the shop want to pay for it?
Agreed. But it can also mean not actually achieving at all what you set out to do. I don't know if that is the case for Loom specifically, but that seems to be what was implied by the parent comment.

I imagine a future textbook might read:

The petroleum age:

A period where advances in chemistry and materials outpaced cultural and administrative development. Early on, Capitalism was proven to be the most productive economic system in the war-time economy, but this posed a problem once World War 2 had ended. Western industry pivoted from war spending to consumer spending and the post war period ushered in rapid improvements in quality of life for average members of society.

Unfortunately those gains came at the expense of the environment and are being paid for by the current generation and generations to come. While it took only a matter of years to transition from a war driven economy to one based on consumer goods, it took nearly a century (possibly more) to transition towards sustainable methods of production and consumption.
Cursors are one of the most useful conceptual abstractions for information processing. Besides the concrete aspects of position and seriality, they form the building block of stateful selections which is a must-have for non-linear editing. Text editing feels fluid because the cursor is pretty smart at going where you want to be - or in the case of vi, it's good at being precise and explicit in skilled hands. I often start defining problems around editing tasks in terms of what cursors and selection are going to look like.

One of the things that I think gets lost easily in graphical interfaces is the cursor; it turns into some kind of ad-hoc mix of mouse pointer, "keyboard focus", touch inputs, IME, viewport state and other things filtered and shaped into some sort of behavior that depends entirely on the application code. These UIs have to be super-smart to work well, and they can be mostly consistent in the average case, but it's also unviable to automate them without great effort.
Now that's just nuts.
I dont have an exact book or course to recommend, but rather how to approach school courses...

I'm Canadian, and went thru post secondary in Canada. This is coming from someone who did not program for fun in highschool, had no family support/introduction to IT, no extra curricular programming introduction, etc.

I went to a collage instead of university. My first year computer courses had lab sessions where our teacher helped with programming assignments. There was ~10 kids in class. Uni classes were a few hundred kids in a single class and lab sessions were ~30 kids. They had TAs (teaching assistants, graduate students with no industry experience) instead of their professors during programming lab sessions. I got the same course credit, much cheaper tuition, and a much more practical programming education. I transferred to a university to finish my degree and I was embarrassingly ahead of everyone else when it came to programming.

Whatever course you do take, look for passionate people with a teaching background and a small class size.
Maybe it saves electricity for the refrigerator because people open the door more infrequently?
Why would they pay for it and then haul and dump it somewhere?

With taxable accounts, it is legally your assets, gains or not. You pay taxes when you sell. Just like with a traditional, non-Roth IRA: you pay taxes when you withdraw. The IRS makes the rules.
If you are not afraid of unsafe blocks and extern "C" functions, it is possible to call a any C api directly including Win32 API for GUI graphical user interfaces. On Linux, one can call Gtk directly or call Qt through a custom C wrapper. The only problem is that both methods are not cross-platform. However, one with enough motivation can develop a cross-platform unified wrapper or interface that abstracts Gtk, X11 and/or Win32 API and MacOSX cocoa API.

Calling Qt5 widgets through a custom C-wrapper may be a better approach than reinventing the whell since Qt already abstracts Win32 API, Unix X11 (X Windows Systems), Unix-Wayland, and MacOSX Cocoa .
Phobic doesn't just mean afraid. Hydrophobic molecules for example.

Whatever you call this sort of thing (predatory or otherwise), obviously it goes into your EV estimate/swag.

FWIW my answer to this stuff is never take a salary so low you would be unhappy if it tanks, which isn't the same thing as valuing equity at zero.

If you can legally invest in an asset in a taxable account, you should be able to invest in the same when its an IRA. Anyone can take advantage of this. Why do you want to restrict the way people invest their retirement funds?
> proceeds to describe an unreasonably substandard school district

What you might not understand is that these issues are not uncommon throughout the US. Not just in K-12 but also college/university. Otherwise excellent schools are stuck with bad teachers or professors who cannot be fired or otherwise dealt with because of the range of protections afforded to them. Job performance issues that would get anyone fired in any other job have no effect on teachers. More accurately, the process is long, difficult and very expensive.

So, no, my description of a couple of bad teachers in our district does not turn our district from good to bad. There are probably hundreds of teachers in the various schools we have in the district. Only a few of them are bad and, objectively speaking, should have been replaced years ago.

The best I can suggest is that you google "why bad teachers don't get fired" and read a few articles on the subject. You can be in a good school district and still have these issues.

The bottom line is that our system of education does not optimize for results that matter. Truly good/brilliant teachers should be recognized and paid more. Bad teachers should be filtered out of the system as quickly as possible.

Here we are, talking about an article that claims kids got shafted for having issues for ONE school year and we can't get rid of bad teachers who affect MILLIONS of kids over DECADES. How does that make any sense at all? The same bad teacher teaching science badly for twenty-five years is worse than what may have happened in 2020.

One of the things my kids tell me with some frequency is that when I teach them science I bring it to life, it is fun, engaging and interesting. Same subjects covered in school, we just explore deeper and wider than they would ever cover. Inspiration is massively important with kids. You can destroy a kids' interest in a subject by doing a shitty job teaching it.
Or do they open the door more frequently to see what's actually inside the case?
> Molecular graph convolutions "also work well"

What is the metric for "working well" here?

My point is a graph convolution will have a hard time distinguishing the haouamine atropisomers, because they have the same graph, but very different activities.

This sort of weird shit is the norm. Like some molecule that isn't the actual active form but needs cyp450 to be activated. But it won't be if you add a methyl group that reduces it toxicity, because that methyl blocks cyp (not your target even). But only in college student pre-phase I volunteers, who happen to be predominantly white male college students looking for beer money

In the end your corpus is going to have to fall back to experiment, which is just so much slower in chemistry than the trivially parallel "scrape every Wikipedia article, twitter tweet, and reddit comment" that you have access to for text corpora; it's more like trying to use ml to decode Chinese, if we only had 3000 Chinese documents to work with.
Seriously though, how does someone even come up with something this dumb? How does one go about thinking of and actually implementing this? How did the development process go through without someone interjecting "why the fuck are we spending $1000s on 6ft LEDs when we can just use glass?"
This would be terrible since it means encountering a species with an aggressive first-contact approach and technological superiority.
Great! As a modern resident of planet earth, I’m not opposed to international competition. I’d love for FAANG not to be able to crush or acquire competitors, regardless of their country of origin.

I bet, based on recent history, that most of the upstarts would be from the US. If that isn’t the case, it will be a wake up call and hopefully the US will rise to the occasion.
Only they can answer that. The general point is that people should be able to change their mind; and the argument that 'you used to believe something different therefore you must be wrong/acting in bad faith' is nonsense.

It's still possible that they are wrong/bad actors; but that can't be determined based simply on a single change of opinion.
