My neighborhood is in the backyard of a major public university, so I'm acquainted with the same cohort of kids, along with their parents. The parents tend to be highly competitive, focused, and organized, and come from professions -- doctors and professors -- that select for those traits.

I also know a kid who does practically no homework, but is still in that top-scoring cohort. His dad was the same way. ;-)

Just school is not enough. You also need great parents.

I've noticed that in at least one subject -- math -- very few students from any background retain an interest as adults. There has to be a transition from a subject being presented as a series of hoops to jump through, to it becoming an actual passion. Whether that transition occurs is a coin toss. It's easy for people to get busy enough at something productive that doesn't involve math, and so they don't miss it. At my workplace, the small handful of people who are considered to be "math people" come from an apparently random assortment of backgrounds.
The problem with headlines such as this is that the cost figure is not put in context. Specifically, "is the 55 billion worth it?", instead of just "doing this thing costs money".

I'm also guessing that the name 'heaviside' is a reference to the Heaviside step function. Which of course, looks like a vertical takeoff, and implies that this project is a "step function" in flying transportation, etc..It's a pretty great name.
> How can you hold it and at the same time advocate against their choice to use a system that doesn't have the ability to install apps from untrustworthy sources? The availability of such systems is obviously an increase in available choice, not a decrease.

Saying "doesn't have the ability to install apps from other sources" is the same as saying "doesn't give you the choice to install apps from other sources" -- it's removing a choice.

If you don't want to install apps that aren't approved by Apple then... don't. You could choose not to even if your ability to choose was not restricted.
Herd immunity is important too. Not everyone, and especially those most vulnerable to flu, can get vaccinated so helping keep it down in the general population helps.

I was corroborating the backdoor point. I didn't read the rest of the comment cuz I was too busy going through a ton of threads in prolly 15 minutes. Also, I stayed rate limited voluntarely from way back to deal with being on social media too much. By default, I don't comment or elaborate most of the time in case more important stuff comes up needing my commemts.

It did. There were two chances in that timeframe to do some good. One was a set of comments on robust software at 4-5pts with a two follow-ups in comments who plan to learn more. Another was necessary reminder banks can themselves cut funding off opponents like they did Wikileaks. That was 5pts with 2 supporting comments. Whatever you expected me to reply to was presumably going to use up my few comments to do less social good.

I figured I'd throw one your way since you or anyone following this may not know why I don't comment as much in situations with lots of back and forth style discussion. It use up all my comments for probably nothing. Now you know why I didn't reply to several of yours done in that way. Just the rate limit doing its job, Sir. ;)

Edit: I'm keeping everything but "sophistry" I edited out. Although sleepy as hell from 13hr days, I checked out your other comments in that thread. My memory is too bad to know what NSA programs you were calling or not calling in the past. That commenter might be full of shit about that. Original comment stands since it was just as a corroboration they were doing it regardless of what you said.
> basically just about definitively showcasing a problem where using a classical computer would take super polynomial time, but with a quantum computer ends up taking some significantly lesser time complexity.

Quantum computers should only really be able to outperform classical computers on quantum specific problems.
Private license plate tracking.

At some stage license plates will have to disappear, but then you move to facial recognition for cars and other meta data, they probably have unique sounds for instance.

I'd try and do a app like https://en.wikipedia.org/wiki/List_of_barcode_games

You should know how to monetize it.

(Obviously facial recognition works equally well here, but there is some regulatory attention, although none that would stop you)

I'd also look at things like using neural nets to detect race and/or underlying genetic structure from visual, audio and other metadata.
The old KitchenAid mixers are bulletproof and absolutely top of the line. My mother inherited one that was built in the 70s and it still gets daily use.

The newer ones feel much cheaper. My wife has one of the fancier new models, and it just feels like a much inferior product. It's the same design, but everything about it works less well than the older iteration.

Pretty much. I wasn't around in the 60's or 70's so I can't really tell you what reaction was like then but by the mid-90's if you talked about it you were a "tinfoil hat" wearer.
Ridiculous. It's this bizarre viewpoint that's destroying our society. SJWs will never be satisfied because destruction is what they want.
I have a suggestion:

- hop on LinkedIn

- searching for people, look for "software remote" with the location filter set to Finland

- find some people that have and/or hire for the kinds on jobs you want

- do a bit of research on their company

- reach out to them and see if they'd be willing to do an informational interview on how they got the job, and I bet some of them will refer you for interviews (ever heard the phrase if you want advice, ask for money, and if you want money, ask for advice?)

This may be insensitive (and I apologize if it is) but if being referenced by normal pronouns is enough to drive someone to commit suicide (or cause emotional distress), I'd argue that this person is in more need of medical treatment than having his or her quirks pandered to by others.

My thoughts exactly, this looks very similar to plotly Dash. Perhaps the creators could share their thoughts on how this compares.

I’m sorry if this is extraordinarily offensive, but my understanding is that, putting aside his extraordinary success in business, Steve Jobs was a mentally ill manipulator and child abuser. I don’t see why I’d put that much weight in his advice on things beyond maybe the above.
My experience is in the context of teaching mathematics in particular.

Mainly calculus because that is be there level at which pedagogy theories are typically experimented with most. In upper level classes are typically straight lectures.

Edit: I meant "opinion" in the sense that you don't really have much to say to your partner about a technical topic you don't understand yet. And in much of math you don't have intuition you can verbalize until you've worked many problems, which means the time to have conversations with your peers about it is probably not the same time you're learning it for the first time. That may explain why in practice the students who read the book before hand are often really just instructing the other students when they are having discussions.

To truly succeed as developer, you need feedback, I mean team and actionable feedback: code reviews, stand-ups, design doc reviews, etc. When you are able to explain your ideas to a group most of the time you grow, as you need to make sure you are doing your due diligence when you present your work.
Good question, not sure. Haven't actually needed an install channel that wasn't through F-Droid (since it supports custom repositories), and would generally be wary of new ones.

PSA: be very careful with what you query in BigQuery on this dataset! You will be billed $5/TB scanned. I was using this dataset a couple weeks ago for fun, and ran up a $60 bill in about 10 mins. It’s important to understand that using WHERE doesn’t shrink the size of your query; instead your FROM clause should only be limited to a single date or month... not ‘*’

It's interesting that even such basic usage of binder is buggy. It's long been known that binder is horrible code, but I didn't know it was quite this bad.

It's unfortunate that Google chose to use a custom IPC system, binder, for Android, instead of changing Android's design to better fit Linux. If binder was in use outside Android, I expect this bug would have been caught long ago and certainly would have been backported to stable.
With clothing, I generally find that the less I spend on clothes, the better they are. A $10 pair of Wranglers from Walmart holds up much better than the $100 pair that comes from a name-brand outlet.

Probably the best pairs of shorts I ever bought were some weird brand that cost $8 apiece at Sam's Club...
This looks really slick, can't wait to try it out!

If anyone is curious about other tools in the same space, our data scientists use Dash[1] and plotly to build interactive exploration and visualization apps. We set up a Git repo that deploys their apps internally with every merge to master, so they're actually building and updating tools that our operations, marketing, etc teams use every day.

If You Existed in Multiple Universes, How Would You Act in This One?
> This argument has been a bit winding but to recap. I started out saying BTC was getting less efficient over time, you said it wasn't, then agreed it was.

You originally said that it gets less efficient as the technology improves. That statement is false. It does however, get less efficient as the price rises. So you should only be concerned if you expect the price to continue to rise.

> You suggested it wasn't manipulated, but we agree there's tons of data that shows its brutally manipulated.

Also false. There are a bunch of exchanges that fake volume. Those exchanges do not manipulate anything, however. All they're trying to do is scam ICOs out of listing fees. They don't even have real users.

> Next we talked about investing, and you said it was doing great, but over the last 2 years it's down 70%.

I articulated the correct criteria for evaluating it as an investment. You may feel free to propose your own, of course. But I presume you haven't already done so because you do not have a better way to run the analysis.

> So far we agree it's performance is better than the bolivar but worse than the turkish lira. Yes, if you bought for pennies and can sell for thousands you did fine.

Over the time period you cherrypicked, yes. If you choose a starting point at random from its history, however, i'd bet it has performed better than any other currency on earth, on average.

> It's also probably not the single best investment in history, if you ask anyone who invested in Facebook's seed round.

Buying Bitcoin on day one was almost certainly a better investment than investing in FB at any stage. I don't know what the terms of FB's seed round was, but let's say you paid $50k for 1% (valuing it at $5mm) of FB. Today that investment is worth an astounding $5 billion, an excellent 100,000x return. However, in March 2010 you could buy Bitcoin at $0.003 each. That's a 2,666,666x return to date.

And that's March 2010, which was the earliest time I could easily find a price for in a Google search. In 2009, when it was actually started, who knows what you could have gotten it for.
This is very cool. One very important application would be simply recording competitive games. There are electronic boards that can do this, and they are ubiquitous at top level events. But they are infeasibly expensive. At our chess club one selfless and heroic volunteer inputs all the scoresheets into a PGN every week (shameless plug: he uses my chess GUI, Tarrasch https://triplehappy.com). But it takes something like 5 minutes a game, and gets tedious after a while. I have thought about trying to build a phone app to compete with the electronic boards, but who has the time? You guys do!
The biggest piece of data that speaks to me against hours of homework being generally necessary for learning and academic success is homeschooling (at least secular homeschooling). Many homeschooled children, especially pre-middle school, have academic periods that last for a maximum of a couple of hours. Yet, these children are able to integrate academically back into traditional schools and excel.

I'm one of these kids: I was homeschooled for several grades due to my family traveling, completed my lessons in just a couple of hours per day (sometimes doing two lessons in one day so I could take the next day off). I successfully transitioned to a regular high school (with plenty of homework), did great, and went to one of the top and most difficult universities in the country where I also did quite well. Even though I had hours of homework in high school, I didn't seem to suffer from not having spent 10 hours a day in middle school doing school plus homework. I wasn't "unprepared" or otherwise unable to handle the suddenly significantly higher workload.

Of course, this isn't very scientific and this also doesn't prove that homework isn't necessary in a traditional school, but it does suggest that something is very wrong in traditional early education if hours of daily homework are necessary on top of 8 hours of lessons to achieve similar results.
the source is me, and the reason why I said that is because they usually block you from being root on your own devices... sometime, bugs like these are the only way to really own your device.
if it makes you feel better, their API is text based and doesnt use message delimiters, so update TWS with great care, because a single new character off in any message will break your entire stream of data, order execution(and especially combo) entries, etc..

They also have some of the worst real time market data available (intraday), absolutely horrendous historical market data request rate limiting and more. Great brokerage, but if you're interested in API for more than orders I recommend other services for realtime data
There are tons of regulations around gardening (illegal plant/seed imports in many states, regulations on how your yard looks, sale of produce); playing instruments (when/where/how loud); sports (depending on context); cooking (for public consumption or distribution, even if free); sex (although most of those are going away).

Empathy and courtesy have nothing to do with referring someone by generic pronouns. No one is being unempathetic by refusing to call "Joey", Joe, or not referring to Nat by their full name, Natalie. These are all personal issues that one must deal with on their own, either by disengaging from the situation or escalating however they desire and finding a resolution amongst themselves.

Pronouns are no different - if you want me to refer to you as her, and I don't, then you and I will have a problem, not you, me, the mods, my boss, the government, etc.

> The ideological high horse isn't very high if one knowingly goes about hurting people to stay on it.

I have heard this time and time again. If misgendering someone is hurting them in any way, I'm suspecting the solution is for that person to disengage from society, not for society to cater to that person's needs, because they will be misgendered day in and day out for the rest of their life. If someone believes they are being gangstalked, society doesn't modify itself to ensure no one within 500 meters of them has a predictable schedule.
It really sucks that if you run a site where people talk, you take on the responsibility to police what they say. The legal system seems to handle scale relatively well but community standards of niceness may not be easy to formalize/scale.
Sometimes i consider myself lucky that i don't know anyone seeking special pronouns - because i imagine i would repeatedly use what i visually see, not what they request.

These days i seek to find a gender neutral word i can get into the habit of using (it, or they, or something similar), for fear of mis-nouning someone. Though, i also have the fear that if i use something neutral, when someone requested a specific non-neutral pronoun, i may be negatively impacted.

As someone "on the spectrum" social norms are already difficult. All of this talk just makes me nervous.
Trans individuals and other marginalized people often spend a lot of time online as a kind of safe haven from difficult personal circumstances.

People online can be horrible asshats to a degree they wouldn't dare be in person.

These two facts tend to collide and go bad places.

I am not ashamed in my views that there are differences between races. I didn't say one is better than other, just that there are differences which are partly cultural and partly genetic. But I won't say it aloud in certain places because I know people will react like you.
That's incredible if true. I've never cared about often being misgendered on the internet. I've also never cared what gender a stranger on the internet is. If I know their gender I might use it but I could also easily forget what they are or mix them up with someone else. Nor do I care if someone mistakes what country I'm from or what political party I vote for. These facts are immutable and no number of mistaken netizens can change them.
> If you're struggling, you're learning.

Just for the benefit of all the people who will be struggling with burnout at some point in their lives:

If you are struggling and trying new approaches then you are learning.

Struggling and doing the same thing over and over won't end well, and isn't helpful to or expected by anyone.
Absolutely. But we can't look at workers in a dying industry like coal mining and say "Hey, your industry is dead. Time to re-train. Hop to it!"

The society that benefited from having these workers should give them time, money and resources to retrain. Some of these people have their identity wrapped up in their job (as you allude to), so the psychological jump may be the most difficult of all.

Maybe we should have insurance for large industries that are essential to society (I can't see how that could go wrong!) ;)
From my experience, this is not necessarily true, even when a phone is advertised as unlockable. I know that Huawei phones, for instance, had two different unlock modes. One called USER Lock, and the other FB Lock. The unlock codes given to users only applied to USER Lock, which means only some partitions could be modified (e.g. recovery could be modified, but fastboot was restricted). I'm not sure whether or not other brands have similar "protections" or not, but I wouldn't be surprised it this was the case due to DRM.
Nice details in the report. Come on DO, this was the most annoyingly PC, lawyer sanitized, non-scientific RCA anyone here has ever read. Here's the BLUF line: Don't cause issues. That causes problems.
I think it's a concomitant aspect of civilization itself. I mean, it's only what? 12K years since we started living in towns, right? Despite it's advantages civilized life kinda sucks in general. I think people long for the pre-civilized "Golden Age" and that's the underlying root of the apocalyptic longing for the world to end.

(I'm not saying that pre-civilized life was an actual Golden Age, just that it satisfied us on a deep biological level in a way that urban/civil life doesn't.)
