Almost correct.

The mean, median, and mode are three types of averages. None is 'the average'; though if you asked someone random on the street they'd probably give you the mean average.
Wouldn't it be possible to block this attack by flagging all tweets containing the Bitcoin address in question? I would've assumed that Twitter could do something like this, maybe even already set up an automated system.

I don't like take homes for two reasons:

1) It's less time spent talking with potential coworkers. Which for me, coworkers (and how we work together/get along) determine about 90% of how satisfied I am with my job (assuming pay/benefits are standard).

2) You're still going to require me to take a day off and stand up in front of a whiteboard anyway eventually. Every take home I've done is an early stage filter. The final round is still a whiteboard panel.
Will anything change in the near term (~2 years), I would bet not. I sure hope the way interviews are conducted changes. After all, most of us aren't trying to spend many hours on sites like leetcode.com. I find those sort of problems to be fun and enjoyable on my free time, but they can be VERY challenging under pressure.
OP's point holds. A third party likely has a less-rewarding bug bounty, doesn't it?
I've just added a more detailed source to Wikipedia (also from ASN), but it doesn't contain any new facts. A cursory google search didn't yield anything reliable confirming the parent's version.
It would be interesting if the scammers started sending back twice as many bitcoins, as promised, from the same address. It could be a real-time ponzi scheme!

Yeah, I also don't understand how one can have multiple destination addresses in a single transaction.
Sad not to be mentioned, despite the update talking about a lot of my independent work last month or so. (discovering the HW issues, suggesting/verifying the fix, writing the USB-C/HDMI driver enabling the whole convergence thing) But I'm very glad about the progress PinePhone is making. The momentum is incredible.

If anyone is interested in original info from the author of the USB-C/HDMI work, I also put useful information/observations from my work on the kernel and PinePhone here:

https://xnux.eu/devices/pine64-pinephone.html

The current thing on my radar is writing a power manager for the modem. :) That will improve the standby from 24h with the modem active to ~90h.

EDIT: All is well, btw. There's just a lot of pressure on pine64's small team, and it's hard to keep up with everything.
And it seems that it's still compromised. Tweets get deleted and then they re-appear.

Ok but after they clean up the site and fix these issues it will be there.

And why not?
One last thing:

> So even more important than the 'regional' strategies now in place, would be for people to declare & behave consistently with their own personal risk-tolerance. At an extreme, this might include wearing some outward declaration of your risk-profile, and segregating shared facilities, by place or time, to minimize interactions between "let 'er rip" & "avoiding" subpopulations.

Yes, exactly this. This is another reason I hate universal masking, because even if I think masks work when worn properly, I still have to assume that everyone is wearing them because they're mandated, but don't actually know how to use them properly.

I would much rather have it be voluntary, and then if I see someone wearing a mask, at least I know they give a little bit of a fuck. Now granted, I still wouldn't be able to (if I were trying to avoid infection) assume they knew what they were doing, but it's better than the current reality where, say, employees are forced to wear masks, and then the moment I ask them to repeat something they said because masks stifle speech, they immediately pull down their mask and tell me what they were trying to say, completely defeating the point.

I love the idea of literally signalling risk tolerance. The only thing is, that still requires ceding public space for some portion of time to the super freaked out people, which is a losing battle, so ultimately I still think we should stick with the "old" way of doing things, which is: if you're a germaphobe/agoraphobe, you stay in your damn house and watch netflix for your whole life like you did before, and everyone's "happy".
Thanks, I appreciate the words of encouragement!

Kudos to Coinbase- I tried sending a small amount to the account after seeing Elon Musk's tweet, and Coinbase prevented the transaction from occurring.
So I’m done waiting, and just had to order one. Even went for the convergence edition.

very nice work
I am pretty sure I have studied every interpretation and explanation of spinors and the non-simply-connectedness of SO(3) rotations, and I eventually finally understood it -- but, by ignoring explanations like the 'belt trick', rather than embracing them. I don't think this article makes it any better. As long as you're stuck on quaternions you're not going to be able to see what's going on, and the belt metaphor just adds complexity as well.

The version that currently makes the most sense to me is this:

* Quaternions are a complete distraction and should be ignored. i, j, and k are (xy), (yz), (zx) bivector rotation operators (up to a factor of -i or something like that). Pauli matrices are the same and should also be ignored.

* The factors of "theta/2" in the exponents that are used in representations of rotations using quaternions (rotating vectors with e^(R θ/2) v e^(-R θ/2)) are distracting and should be ignored.

* The best way to see what is meant by "the space of rotations in SO(3) is not simply connected", you need to think about paths in _rotation_ space carefully. More carefully than I did as an undergrad! (Although I'm sure this is obvious to people who have studied the approach math in a course?)

The wrong approach -- which I was stuck on for years -- is to think about a point on a sphere in R^3 moving around. A vector that starts at, say, +z in R^3 and is rotated by 2pi in the xz plane ends up where it started exactly.

The key insight is that 'non-simply-connectedness' refers to _paths of rotations_, rather than paths of what the rotations act on. So imagine gradually rotating that vector +z in the (xz) plane. If you go around by 2pi, you've made a path that can be modeled as an exponential operation: e^(2pi (z^x)).

The question is: can this path be deformed to the identity path? It seems like it can -- you just change from rotating +z all the way around a great circle, to a smaller and smaller circular path until it is just rotating in place (and xy rotation). But somehow when you collapse it, you still have a 2pi rotation! It's just that now it's a 2pi rotation in xy rather than in zx. No matter what you do, if you collapse the rotation path to be the identity on the +z vector, the resulting path rotates _some_ vector by 2pi, instead of keeping it at the identity.

So in physics, it's not that there is a negative phase factor _per se_ that matters for physics. It's that there are two physically distinguishable states (identity rotations and anti-identity rotations) -- so two different electron wave functions can't be identified as the same electron, because they are a 2pi rotation apart just due to how they got there. And the fact that we _model_ this is as a negative sign is entirely an artifact of our obfuscating choices of mathematics for the situation.
27% of transgender workers reported being fired, not hired, or denied promotion in 2016-2017 [2]. That's ~530,000 people [1], and really just the tip of the ice-berg. Until like 2 weeks ago that was completely legal federally, and in the states where it's most prevalent.

Three of my high school teachers were fired for being gay. One of them was outed by a parent who lived next door.

I was fired from my first job (at a secular for-profit company) for not tithing.

High-profile social media blowups are really trivial compared to the work-a-day homophobia and borderline theocracy that pervades vast swathes of America's land mass.

This is where I sort of miss the boat on the concern about cancel culture. Yes, those people shouldn't lose their jobs for expressing themselves. But also, where the hell has all this outrage been while LGBT people have been systematically excluded from any public-facing employment in huge swathes of the country?

Exactly, and it's also worth mentioning that alot of these types of laws exist to create criminals when one is needed, and not to preemptively seek out violators. That's not necessarily morally any better, but at least it removes the spectre of "I'm going to get killed the instant I land at the airport" feeling that seems to be so common.
Valet mode is a common feature on luxury cars; prior to the fancy infotainment stuff, it was a valet key that wouldn't unlock the glovebox or trunk, but would drive the car.
It is a very precise function, I'll give it that.

> SARS-CoV-2 appears to be an incredible spreader and a poor killer

That's only true because we've been able to treat most people who needed hospitalization. The point of the lockdowns is not to prevent deaths from SARS-CoV-2. It's to prevent the healthcare system from being overwhelmed so that moderate-to-high-severity cases go untreated thus increasing the number of deaths.

It is naive to assume that if a car has a simple radio+CD player with physical buttons that the user will only ever use a simple radio+CD player with physical buttons. Many people will instead use Bluetooth, an aux input, or a radio transmitter to connect their phone to the stereo. Now everything is offloaded from the car's infotainment system to a phone which is even more difficult and dangerous to use while driving.

> No need to bring in animals to explain this. There are a handful of human coronaviruses - I think 4 that are not SARS-related, but I’m on mobile so will have to dig up the study later.

Read the paper, they're making a distinction there because the zoonotic viruses are different to the endemic human ones, but closer to SARS-CoV2.

> Besides, once a virus jumps from an animal it either becomes a human virus (capable of spreading), or somehow is a one-off virus that can jump from animal->human but not subsequently to another human.

That's the point, the zoonotic viruses aren't spreading in humans, but they may well elicit an immune response.
Huh I wonder if freight ships could be converted to become electric/solar powered
I never claimed that installed capacity equals effective output, that's obviously not true. I don't think the figures are meaningless, either, but whatever --

Grandparent claimed that the bulk of renewable energy produced in France is hydro (and called me disingenuous). I just cited some statistics -- installed capacity as well as current effective output! -- to put his claim into context. Here are some more[1]: Energy production by source in France, 2019, Hydro 55.5 TWh, Wind 34.1 TWh, Solar 11.6 TWh. Obviously anybody is free to assign whatever value one wishes to terms like "bulk of", but those are the numbers.

As a a sender, you have a coin of amount X, and you split it up and send it wherever you like

If your coin is 1 and you want to send one person 0.2 and another person 0.3, you can do that as a single transaction to three destinations, one with 0.2, another with 0.3 (to the people you’re sending to) and a final one with 0.5 back to one of your own addresses (aka a change wallet)
> being punished for being police officers.

Some of the logic is that bad police behavior is widespread enough that every "good" cop works closely enough with at least one "bad" cop, and yet via observation of outcomes, does not correct that bad cop's behavior (or doesn't correct it enough). They're thus complicit AKA bad cops themselves, and thus there are _no_ good police - everyone is sufficiently tainted.

The Godwin's Law version of this logic at work elsewhere is the German saying "if there’s a Nazi at the table and 10 other people sitting there talking to him, you got a table with 11 Nazis."

The folk wisdom encoding "a few bad apples spoil the bunch". Doesn't matter if they were good apples going in, they're all bad apples now: the bunch is spoiled.

That's a very broad generalization.

I've been getting paid to write code since 1998. The last few years in management. So I know something about actually being a programmer.

I hired someone who was awesome from a technical knowledge perspective. Friendly, personable, smart, driven, etc. Loved talking tech with him and he had really great ideas.

Anyway, the problem was, I'm running a startup and every single project he was on he tried to model it as "the perfect open source project". So instead of doing something simple in a couple of days he would build this really well abstracted, over engineered (but pretty damn good code!), "beautiful" thing that would take 3 or 4 weeks to deliver.

In the end, it didn't work out for him.

Anyway, my point is that it is not true that programmers hate working on the same thing for longer than necessary. I do. You do. Many others do. But some just love being architecture/purity astronauts and refining that 3 line method into a 7 class inheritance hierarchy.

This kind of pictograms always reminds me of Apple. When a Mac can't boot because of corrupt boot files, it shows a "prohibit" sign.

I suppose the reasoning was the same—not all users can understand English. But in this day and age a pictogram is in fact harder to search for because people describe it differently.
Well, yes. That's why I mentioned the rounding mechanism later. However, US-style sales taxes make the process of applying that more difficult because you can end up with weird numbers, whereas with VAT, you can pre-round things to minimise the disruption.

^ This should be mandatory reading for anyone. Especially people that are obsessed with the idea that all vaccine candidates are inherently safe. (Unfortunately the term "anti-vaxxer" now gets thrown around for any actual legitimate discussion of the risks of untested vaccine candidates).

I'd note that ADE literally happens in Coronaviruses, so it's extra relevant. It can even happen outside the context of a vaccine, and may play a role in the pathology of severe SARS-CoV-2 infection.

Also consider the new Icegiant ProSiphon Elite [0]. Mine is arriving in September (due to Coronavirus related delays) but initial tests of prototypes by LTT [1] and others showed better cooling than AIO water cooling. Also since it uses dielectric fluid there’s no risk of leakage and frying your expensive computer. It’s $169 MSRP but based on what I’ve seen seems worth it. I’m not associated with them in any way just think it looks like a cool new product!

Case closed then, F policing as a profession and everyone who sees it as a vital component to a civilized society? NYPD are well aware that they are vulnerable to this virus and in turn to spreading it not just to you but to other cops, but in order to keep a lid on rioting, while growing increasingly shorthanded in number, in tools, maneuvers, plainclothes units, or effecting arrests (regardless of the disinterest in those being prosecuted), they need all the oxygen they can get. I'm not saying that $42,500 is not enough money in NYC, just that this is an exigent need for oxygen, not biological warfare.

First, azangru was talking about "statements about the physical world". For that kind of statement, if there is no objective correlate, then you're kind of in a quantum "many worlds" vs. "collapse" situation. That is, people have opinions, but it produces no actual physical difference which one is true, and many people have concluded that the dispute is both unproveable and pointless.

And if we're talking about something that isn't physical, I suggest that it's still the same. If there is no objective correlate, then... let people have their opinions, but don't label either side "truth".
You are correct. It was a poor (and in poor taste) attempt to be snarky.
I can't find the tweet now, but Tavis Ormandy once talked about companies share prices often rebounding after a breach, so he was buying stock in companies that got hacked. Equifax was an example, I think.
The fact that state-level actors are doing this kind of thing is all the more reason to foster a domestic culture of refusing to be manipulated by it.

Otherwise, we'll wind up in a place where relatively small digital ad buys by foreign actors can create years-long mass hysteria.
I don't do that. When I demo something I need feedback on, I demo the best version I've got. If it still requires work, I say so. This seems to work quite well for me.
Just because two people say different things doesn't mean the truth is in the middle. One side can just be completely full of it.
I think long term it has enormous potential to take over as _the_ language for modelling.

The reason is that for every hyper optimized climate model there are a thousand small or medium models. For these Julia offers sufficient performance and excellent developer experience.
