Indeed, most locks are societal items instead of actually being difficult to defeat.

This talks specifically about particle pollution ( not CO2 emissions ) which has already been largely regulated out, "up to" 1000x of a very small amount can still be quite insignificant.

Given the misleading nature of the press release title I think I'll avoid reading the actual result and mentally mark "Emission analytics" as one of those companies.
I know relu(-x) is not relu(x). I think the equations I wrote are correct. My point is, your version is not fundamentally different because we can get your effect by using the standard version and flipping the input to the network, the M matrix and then the output will come out with the sign flipped as well. If you put a sign-flipped fully conn layer and a softmax on this (for example) the result will be the same.

The only reason that yours might be better is an asymmetric distribution of x o around 0. If you flip the sign on x, you should get the same benefits.

To summarize: your net is not exactly the same as the usual one, but if you train your version on x and I train the usual version with -x, our results will be indistinguishable.
> Does the randomization happen at each new invocation of Bluetooth?

Doesn't matter. https://content.sciendo.com/view/journals/popets/2019/3/arti... - note that this is seemingly aptly published in a conference on privacy. Yes, what you want to use bluetooth for would likely work but we've worked a decade or so to prevent it.

You'll likely realize from my other comment that I dislike the general idea of this but honestly, I don't get the approach from a technical perspective. The idea is an app for smartphones, right? You have all kinds of sensors on those besides BT, e.g. WiFi, GPS. Comparing timestamped movement profiles would give you much better matching than approximating this stuff via BT environments, which these days at least theoretically are designed to explicitly prevent your use case and just seem to limit yourself artificially. The reason you dismissed geolocation is perfectly valid but that also applies to Bluetooth identifiers if you treat them as reliable indicators. If I get a (hashed or not) BT ID of infected persons, I can identify those - at the very least if their device is in my vicinity. And not only while this issue is active but afterwards. You would have to protect that data just as much, putting another ding in the "potential privacy implications" of the approach.

That's a nice chart to keep in mind, but kinda tangential. Joe's point is that with the right tools, it is sometimes faster to write your own solution than it is to pick one from all the available canned solutions and learn to build & install & configure & use it (and figure out what to do when it doesn't work like it's supposed to).
I used to be one of the "old guys" fighting against git because subversion is "good enough" and I didn't want to relearn a new tool. I finally had to learn git because a project I contributed to made the migration and I could no longer postpone it. I'd never, ever, go back.

At this point I'd go as far as saying that git is objectively superior to SVN because it does everything SVN can and then more. One caveat being potentially very large repositories and especially repositories containing sub-repositories, git was terrible at that and while it's improved over the past decade it's still a bit messy. Unfortunately in my experience these types of repositories are fairly common in proprietary codebase where people often don't hesitate to commit big binary files alongside the source code.

Still, I'd say that as a rule of thumb if a codebase is still in active use it's probably worth taking a week or so to migrate it to Git unless there's a very good reason not to.
There's a clear-cut "scissor statement" that you can use to divide programmers into two opposite sides. You ask the following question:

"--If you need to invert a 2x2 matrix in your program, do you write down the algebraic formula for the solution by hand or do you call a linear algebra library? (that you would not need otherwise)"

The answer to this question is obvious to most programmers. Also, it is obvious to them that the opposite answer is clearly wrong and absurd. Unfortunately, not everybody gives the same answer!

In fact they still recommend doing a physical verification by comparing the safety number.
> I don't think there's anything about dynamic scripting languages that makes them intrinsically difficult to thread any moreso than any other category of language

I think there might be some intrinsic factors:

1. Languages like Python don't want to expose the program to undefined behavior. Defining some trivial class, and then manipulating it from two threads at the same time, is not supposed to crash the program or introduce horrible security issues.

2. Languages like Python have "property bag" objects. That means (someone who knows better should check me on this) that most writes in a typical program are hash table operations, rather than primitive stores of an int or whatever. Locking each table separately, or using a fully atomic implementation, can be a significant slowdown in single-threaded programs, compared to using a GIL.
As quoted by another poster:

> Using a popular family hatchback running on brand new, correctly inflated tyres, we found that the car emitted 5.8 grams per kilometer of particles.

Could it be that tire wear drops off? Initially it's shedding a lot, I dunno, due to surface layer being porous or something, and then the wear drops off to the normal rate?
Space is notoriously expensive... until it isn’t. Launch costs have reduced by an order of magnitude and may reduce by another as full reuse becomes feasible. All of a sudden, you’re using near-commodity solar cells with a higher capacity factor (and more consistency) than on the ground. Power is thus not so expensive any more.

Industry rules of thumb are only good if the industry is stagnant.

> Never work on anything you would regret looking back on your deathbed and spend as much time you can on doing whatever you can’t stop thinking about.

What if the thing “you can’t stop thinking about” would lead to regret later?

In my case, the project I really want to do right now is to start a blog and write about video games. But, I worry if I look back on this time later, I will regret spending time writing about what others have built when I could have been building something myself.

So, I’m trying to balance my time between the writing, and also a programming project that isn’t as enjoyable, but which will hopefully be more fulfilling long-term.
This isn't quite the same thing, but it is one of the articles that spurred my thoughts on this subject. In cpython, gc != refcounting. Instagram were talking about disabling gc, which would have stopped objects which they weren't using from being falsely copied, but wouldn't have stopped objects that they were using (but not mutating) from being copied.
Personally, I'm a generalist in the worst sense in that I've read about a lot and can talk for day about various things, but am only proficient in one or two things.

That is a valid reason for having it as an option. Not to force it.
Death rates aside, it looks like younger people are less likely to even get the disease (not especially surprising). If you exclude the really young people, even the 30 year olds would likely be under represented (I think). One implication of this may be that societies with more socially engaged older people will be more vulnerable to this. E.g. countries where people who serve as frequent touch points to strangers like frontline retail jobs are likely to be older might do worse in this circumstance.
This is just completely wrong, and I don’t want to explain Unix permissions vs actual access control again which has shown up more than once in the thread. Plus, you know what, sandboxed apps basically can’t read or write anything not created by them without explicit permissions.

The standard flow is app tries to access file/folder, dialog pops up asking if you want to allow access, or if you want to allow full disk access (the full disk access part might be opt in for app developers, but app developers with legit reasons to access certain protected stuff do tend to encourage users to do this).

Your apparent lack of knowledge of this (not pleasant but at least functioning) flow makes me wonder if you’re even a macOS user. Maybe just a Linux user who came to score some points?
How to fix it? Get involved with your local DSA chapter. Work on putting socialists on your local ballot and getting initiatives passed locally. Educate your friends and neighbors that 'socialist' policies are much broader than what has been demonized in the US since the red scare.

> calling back and forth between C and Python

Yes - the trick really is to move your accelerated code away from python's object model, because then you can drop a lot of overhead and also release the GIL. Tricky, though. Out of interest, did you see any improvement from pypy or numba?

>We prescribe drugs too casually (South Park's ritalin episode, the current opioid epidemic, young hiphop performers promoting Xanax) and at the same time the war on drugs is still going on, and the "establishment" doesn't really want to accept effective drugs that have "immoral" side-effects (eg. look at the story of how ketamine treatment for severe clinical depression went down, it passed FDA review, but it requires a separate clinic, it uses the "boring" version of the molecule, and thus might not even worth the cost).

I was talking to someone recently about medical marijuana on our state. We have it, but it's supposedly a complex process. He brought up something about "having to exhaust all other treatments for a condition before trying for a medical card". I hope this isn't true, because it seems absolutely irresponsible to prescribe opioids or benzodiazepines for a conditon that could treated with a less dangerous drug.
I think you misunderstand. Especially

The point is the opposite. There is a small net X within big net Y, such that training only X gives the same performance as training all of Y.

There are exceptions, but the vast majority of tech positions at Google are for generalists.

I'm with you up to the last paragraph.

It's not useless. FPGAs have plummeted in cost and there are now open-source toolchains for some of them. There's also a Free commercial-grade ISA that you can use in your personal designs (RISC-V). These days, it is not expensive to design your own well-understood computer which can run microcode generated by commercial-grade compilation toolchains such as GCC. Even hardware production is getting cheapER with shared wafer runs like MOSIS, although custom silicon is still out of reach for hobbyists.

Chin up, buddy. The US is not the entire world, and the pendulum of our generations' zeitgeist can still swing back towards the ideals of liberty and equality of access which the mavens of computing once stood for. You can already buy ARM application processors from vendors other than Intel/AMD, and I would be surprised if we lived in a world where every new computer comes with "management engine" spyware in its CPU for much longer.

Okay, you got me. I am in the camp that says calling the library is (in the general case) obviously the better choice.

My (camp's) reasoning:

1. Your handrolled solution is likely worse than the library anyway

2. You're wasting effort reinventing the wheel

3. You risk adding unnecessary opacity by littering the program with dense math

4. Other programmers will assume there is a pertinent reason you handrolled the algorithm instead of using the library. Now everytime someone touches that code they have to reverse engineer your approach to see what it does different from the library such that you had to roll it yourself (surprise: nothing!).

The two exceptions I imagine are 1) if you really do absolutely need some slightly modified microoptimization of what the library does or 2) if you are working for a platform where there is good reason to avoid even slight bloat (embedded).

For the people who read OP's comment and believe I am (obviously) wrong, what is your camp's way of looking at this?

I’m a generalist and I would 100% recommend it over being a specialist because you get to see the whole picture. You start to notice patterns across different programming paradigms that make you a better developer. You learn techniques to quickly teach yourself and learn about the problem domain which translate into other parts of your life besides computers. I’ve taught myself how to work on cars using deductive logic when I get stuck and software engineering principles to make decisions when I’m afraid I might break something and I’ve improved my personal finances with data science.
The wording of your question confuses me, it's not clear whether you're asking about "large individual concentrations of wealth" as a cause or effect of "economic anything", aka are you asking how one can achieve economic anything without a pre-conditional individual concentrations of wealth or are you asking how one can achieve economic anything while avoiding the subsequent trap of large individual concentrations of wealth.

In context and logically I would assume the latter as those large concentrations are why you get large organisations to manage them, but I wanted to be sure.
