Will it still give the wrong answer if your table isn't sequentially indexed?

That is, does #({[1]="a", [3]="b"}) return 1 or 2?

edit: I see that it still returns 1. That's a shame. This trips up so many newcomers who've been told that "#" means "length". IMO they need to either start calling it something other than the "length operator" or make it _actually_ return the length. Sadly at this point it would just be yet another breaking change.
I'm no network genius either but I just logged into the unifi console thing and created a new wifi SSID with it's own IP range and then had to reconfigure all my IoT devices to point to the new wifi SSID. That was all I had to do.
As someone not in the free smartphone world (yet) - what is going on? What are those UBports and Braveheart versions people are talking about? How's the software stack. Is GTK/QT usable with touch? How's the battery life? Any progress on making open modem?
I actually switched fully to vaping when quarantine started because I figure time for a little bit of change and I can just order it online (I'm sure I can order cigarettes online but all the sites seemed kind of sketchy). I was going half and half before that.
That isn't what the sign says. It's what York is trying to imply from it, because York's made his entire career out of race-baiting.

The purpose of the sign is to show how people who DON'T have those things have been discriminated against because of circumstances beyond their control.

If you're poor, rugged individualism is less important than getting through the day. Collectivism is the more intelligent approach in that situation.

Hard work for a lot of white folks is seen in the context of having "a job that matters."

Objectivity in this situation is a farce. Yes, it's stupid to take out a payday loan. But when your wife just lost her job or you lost your child care benefits and you have to pay rent, you do what you have to do.

Nuclear families are great if you're born into them. What happens when you aren't?

And so on, and so forth.

And the funniest thing about this whole thing? White society is trending away from AAAAAALLLLL of these as the cost of living outpaces inflation and wages stay stagnant.

Turns out that it's pretty easy to check the items off of that list if you have the means to do it.
900000 km/h = 250 km/s. This is fast but comparable to 224 km/s that the sun moves. Our galaxy itself moves at ~600 km/s relative to local cluster center of mass.
I would be surprised if it were an engineer, but not everyone who is employed would be an engineer. When I was at Google two fairly high profile incidents were enacted by contractors (one in the IT "TechStop" group and one a data center tech)
This makes way more sense than any of the other suggestions in HN.

DMs are almost worthless; who uses DMs for anything important? It's for contacting people you kinda know but not really. State secrets aren't transitted over DM, but not because people wouldn't be stupid enough to do it. the people holding them are much older than the demographic that uses Twitter DMs. Worst case with DMs is some new YouTuber drama would be exposed.
This definitely isn't ignorance, it's a very, very common question. The TL;DR on it is: cost.

The most cost-effective way of delivering video is using some form of HTTP streaming (like HLS or DASH). In a nutshell, the player downloads a manifest that tells it where to find chunks of video, which are downloaded and cached in normal, commodity CDNs. Everything is stateless and is scaled like any other form of HTTP download. To do all of this you end up needing to transcode the incoming stream. All along the way through this process introduces latency, and for reference 20 seconds is perfectly normal HLS latency, so credit where credit's due, this is really impressive. One of my colleagues wrote about the state of low latency last year[1], and considered < 4 seconds to be "ultra low latency"...that's really rare, particularly among platforms.

You can get lower latency, of course, but typically that involves stateful connections. All of that cheap commodity stuff that comes with HTTP streaming above goes away, and scaling to a large number of viewers can get extremely costly (and operationally difficult).

I've never seen it done that way -- just used as a pre-screen for an onsite that is the typical code-on-a-whiteboard scenario.
Had one place that used an at home test + a one hour task in the office on a laptop they provided + several more whiteboard sessions (so long they split it over 2 days).
Did you see the costs? Might as well use YouTube.
Local papers are just about the best possible news source you can have. Not to mention they are the actual primary sources that your nebulous 'news coverage' would be relying on.

Voting preference is voting preference. It doesn’t dictate a person’s entire set of beliefs. Personal observations lead me to conclude that plenty of Trump supporters know he’s crazy but still prefer that to the alternative.
I am also highly uncertain of this. Briefly though, elderly people are more susceptible to actual infection, and I would think would be more likely to express symptoms / have higher viral load. So it depends if the marginal likelihood of more symptoms = self-isolating sooner is counterbalanced by more symptoms = spread more easily for a given encounter.

Anyway, ignoring the spreading part, the susceptibility alone does explain it to an extent, as you implied:

> It's the ones that are most easily infected (because of their particular biology, lifestyle, etc.) who are first infected.
how exactly would one do that (pay taxes on illicit $)? are there public examples of it?
The problem with that is that the market assimilates new information rather quickly, so the downward spike in price would be rather short lived. It would be rather trivial for the SEC to figure out a short list of suspects from those who bought to close a large short position in that small timeframe, even in a highly liquid security such as TSLA.
If the star is a direct hit on your planet, it would look as if a second sun was getting brighter and larger, and the heat so unbearable you’ll be dead before there’s any impact.
It’s kind of difficult to explain without you doing it yourself. The closest I can think of, is the ability to suck liquid from a straw but hold the liquid in your mouth instead of inhaling and/or swallowing it, I guess.
Honestly I wish I could bring a kid to work on a regular basis. Before Covid I brought my dog to work every day. Provided the kid is well behaved, why can’t I bring a kid everyday?

Hmmm. That's a pretty good argument. The biological component is probably completely separate, but the lifestyle component, the opportunity part, overlaps significantly.
Did they send one out from Trump as well? Imagine the mayhem if they send out a notice that he’s resigning or that he is launching nukes.
Please elaborate more. First you need to tell me what you think the threshold is; the findings in this paper suggest it could easily be like 15-25% as opposed to the previous figures of 70-90%.
There comes a point in an interview where you're not sure you want the job given what you've seen, and any judgement of the candidate's ability once they've checked out is useless.

You can learn a lot about a person by what questions they chose to ask you, but only if it's not a thing tacked onto the end of a long interview. If they haven't gotten much time to ask you questions, they only have your interview questions to go on. Which you know are not representative of the kind of work you do (but then, why are you asking them?)

So because you only ever talked to them about things that could readily be had off the shelf, and this is the only information they have, they can't know if you're bad at interviewing or some psycho who spends all their time reinventing wheels and then demanding that other people be impressed by your insanity.

The chances of the latter are bigger than you think. So if it's down to you or another opening, they'll take the other opening, and then you've wasted everyone's time.
I'm not excusing excessive force, I'm saying fire bombing in general is a felony and police should be able to arrest a suspect and use force if they don't comply (obviously reasonable force).
Thanks. By the time I got here dang's comments were buried on pg 2.
hmmm... The matrix, the island, and all vampire movies ever.

(I know, the matrix was energy to power computers and the island was body parts, but it's all similar)
If you explain extenuating circumstances to your recruiting contact, you probably can get a chance to reinterview sooner than the usual cool off period (especially if you did well in the earlier rounds).
I haven't done the math on that kind of infrastructure project. I would be very curious (and open minded) about seeing an analysis of how payment for roads plays out, especially with toll roads.

In the Portland, OR area (where I live) there are zero toll roads. Maybe that's why I am biased to feeling like state funding these projects is necessary. If Amazon (and anyone else that uses them) were paying for them, perhaps I would think differently.
> Removing the police is definitely dangerous.

Citation needed.

NYC reduced their "stop and frisk" policies and WaPo analysis of crime pre/post change and the rates were more or less unchanged.[1][2]

NYPD turned their back on the mayor when he didn't show in person to the funeral of 2 murdered officers (which is a rejection of civilian rule of law) then proceeded to do the minimum enforcement required by their employment contract for ~2 weeks. Crime didn't rise noticeably.[3][4][5]

In the 1990s when "broken windows" policing was popular in NYC, crime levels fell but by no more than other areas of the world. It's far more likely that additional policing did little but increase the population of convicted felons and prisons because officials were so hypnotized by "tough on crime" advocates above falsifiable evidence.

My city (top 10 population in the USA) cut a lot of police jobs after 2008 and replaced some of those former police numbers with a "Community Service Officer" role. CSOs are far cheaper, aren't armed, and take a lot of the basic workload off of the expensive officers.

I'm tired of the incessant "we can't reduce their numbers". We've been doubling police numbers and budgets every 2-3 decades and so few people in power are willing to take a moderate stance to say we should experiment and reduce their numbers a little to see if we can save money for about the same levels of crime. It's not like giving police a lot more money actually increases their clearance rates.

The tech industry, if it can manage to do it, would benefit immensely from enacting interviewing methodologies that aren’t ultimately rooted in an underlying need to haze others. It’s as if the CS nerds forgot that when the frats hazed others we were disgusted by it.

> But if the odds of a patient surviving a ventilator treatment is on par with the patient beating covid-19 on their own, and we know that ventilator treatment is harsh and cruel, it makes no sense to put them on a ventilator.

> But most people think of ICUs and ventilators as some sort of magical medical machine that always cures people as long as they get access to it, so therefore we have this weird focus on ICU capacity as if that's the most important factor for overall mortality.

Yes, I totally agree. Maybe didn't make that clear above, but my point was even if we pretend/assume that the ventilators are helping, the effect is small.

I think it's highly likely that invasive ventilation as applied just ended up making things worse.

> And this is because doctors in Sweden place more weight on making sure the treatment does good, rather than opting for maximum intervention every single time.

Exactly. It's just such an American mentality. Same reason we wanted to hold up Hydroxychloroquine, Remdesevir, etc. Not saying they don't work, but that focusing on antivirals detracted from the real discussion we should have been having all along.

We're too accustomed to perfect technological solutions which let us avoid having to face the reality of our own mortality (and the mortality of our loved ones).

Yeah, ditto for Estonia - when I was screening resumes I was shocked to see that everyone was including an (unsolicited) headshot... also many people would write their age too and even sometime their marital status.
How can the tax ever be worse than a sale? Even if the tax is 100% on the profits from a sale it would still contribute to economies of scale at the production end of things thereby subsidizing all other units in countries with more favourable tax rates and increasing the profits in those countries.
But also don’t do that

You want to unlink the transactions
I have no clue! I just heard this a while back on some random video three months ago from an infectious diseases professor. My knowledge of biology is very low, I really shouldn't be speculating publically, I thought it was less controversial knowledge. I've probably just phrased it badly or remembered it in too simple of a manner due to my lack of background here.

I think half is a simplification, it must mean that if you have the wrong type or quantity or some combination thereof, but again I'm guessing and not an expert or even a professional.
I think the answer is we need more innovation. We need a million small startups instead of a dozen tech giants. Software scales but starting up is a moonshot.
On the other hand, I've increased the amount I smoke, from less than a pack a week to rolling over 50 grams (weighed the one I just rolled and there's 0.5 g of tobacco in it). I can smoke inside at home, which is one of the main drivers, I'm on smoko 8 hours a day now. I feel like Boris in GoldenEye bashing away at code while sucking down cancer sticks.

My doctor said that everybody has been one way or the other, either significantly decreasing or increasing the amount they smoke.
> My task is to implement a model that takes advantage of unified field theory to simulate arbitrary bodies in spacetime

Sure, sounds straightforward enough. Start with simple cases (e.g. universe is a unit circle), you can definitely implement useful pieces within two weeks.

> first the mathematical models behind it need to be created then implemented in software.

That's not a real (i.e. user-facing) requirement.

I don’t remember the first lockdown subsiding in any meaningful way. Outdoor dining with household members, maybe? Seems like a marginal economic impact.
It makes sense and something that goes against another agenda so something that couldn't be spread by mainstream news widely.
"LWN recently covered the effort within the LibreOffice project to find ways to support the companies doing the bulk of the development work. The project has now posted a revised marketing plan [PDF][2] with a number of changes, including the removal of the "personal edition" name. Regarding LibreOffice Online: "Following our normal development process, the Ecosystem will release their own versions in their own timing, allowing some features to reach their Enterprise versions before they are subsequently shipped in TDF builds (this allows the Ecosystem to positively differentiate by contributing new features & functionality)".

This post is a bit highfalutin, but it has a good point. You understand quaternions by doing math with them (the same way you understand complex numbers, really). There's really nothing magical about them, and I'd really push back against the idea that a 3b1b video really made you "understand" them -- other than on a very cursory and shallow semi-intuitive basis.
I does make you think. After 30 or so years, they still can’t make an operating system that won’t allow the applications that run on it to bring it to a grinding halt. How hard can it really be?

You are trolling and putting words in my mouth. I'll not reply to this until you reframe your question.
I don't do whiteboard coding. When I thought it was meaningful, or might be meaningful, I did it even though I'm uniformly terrible at it. If I was great at it, I might do it even though I no longer think it's meaningful.

But I'm terrible at it, and I don't think it's meaningful, so I don't do it. Admittedly, it costs me some opportunities, but mainly at companies I'm not sure I want to work for, anyway.

At this stage I'm an old fart with a long resume, and more often than not I get hired by people who already know my work. I guess if I was as bad as my whiteboarding performance makes me look then people who know my work wouldn't want to hire me.
There have been much larger amounts people have laundered this way.
Yeah, the way people will tell me "look at Sweden!", meaning, "look at how awful Sweden did!" is just mind-boggling. I am insanely jealous of your guys' medical/health leadership.

I'm sure the approach of disfavoring ministerstyre bites you guys in the ass for certain types of problems, but for something like this, the fact that the ministers are not allowed to run the show is such a blessing.

(Of course, if we tried it in the US it would almost certainly fail, because even people like Fauci or the CDC head are just completely crazy...but we're not allowed to admit that)

Along similar lines, all the myopic IFR talk made me think about how, if we had a decade where there just happened to not be any major pandemics, a very generic common cold virus could come around with an IFR of >1% simply because there's such a high proportion of elderly people practically on death's door, who have been more or less artificially kept alive and so of course the IFR is going to look bad if it wipes them out.
I'm glad I'm not the only one who finds the preaching on Twitter a bit weird.
I'm not from a country that really does "debate teams", but as I understand them a lot seems to be about "winning the argument", which doesn't strike me as especially great.

On the other hand, it probably makes people better at spotting a bad/fallacious arguments, and gain appreciation that complex topics tend to have multiple reasonable opinions on it – two things we desperately need more of.
I'm surprised and delighted to see someone recommend The Discrepancy Method by Chazelle. I love this book, but even beyond it requiring a lot of mathematical prerequisites, I'm not sure of the use to most software engineers. I think only the chapters on sampling, geometric algorithms, minimum spanning trees, and maybe linear programming would be useful references on algorithm design for most software engineers.

I second the recommendation of Probability and Computing by Mitzenmacher and Upfal. In addition to being much more mathematically self-contained, there is more focus on models and techniques that I imagine software engineers might actually use, e.g. hashing, load balancing.

In addition, Randomized Algorithms by Motwani and Raghavan is a fantastic book, and should be doable after completing Mitzenmacher and Upfal. It goes into further depth on techinques for designing randomized algorithms.

A bit orthogonal but still related to the idea of "what should a software engineer read for interesting algorithm ideas", I really like Approximation Algorithms by Shmoys and Williamson. There is some intersection with randomized algorithms there too.
Fascinating. I've seen political organizations using a zcash address for collecting donations, is that technically any better? I'm aware that creating bit tumblers for laundering currencies in cycles is largely out of practice now, has there been any recently development towards traceless transactions?
