Material on Android supports dark themes super well. Comes with MATERIAL.LIGHT and MATERIAL.DARK by default. It's up to the app developer to include an option to switch in the settings, but this is common in apps that are focused on reading.

Most people prefer light.
IMHO, it will be stupid cheap in no time at all.
Yes, I would agree. Material is clearly designed to brand apps as "Google apps" not necessarily provide the best UX possible.

Ah. He just tried a VR headset in an environment where you can move around. If you haven't seen that before, it's impressive.

You need a lot of floor space to get the real effect of movement. You also need reliable motion tracking and a display image solidly aligned with the real world, or users will fall down, or, in a non-flat environment, fall off things.

This could bring back laser tag.

You would not see any effect, not with just 3 plants.

It's part of the problem - any effect obvious enough to show up with the small resources of a child, is also pretty obvious.

I would do different: Have kids reproduce famous known experiments, and get rid of this useless obsession with hypothesis first. Just do a "hey, that's interesting" type experiments.
Personally, I tihnk the example you describe is rare and that most of the time eye-witnesses and even cameras only get a partial plate, if anything at all.
At the fairs I've gone to they compete on the written portion, and on how well they answer the question, i.e. how well they know the material.

The experiment itself doesn't matter as much.

I'm 22 years old, fresh out of school and I'm as involved in design, recruiting and peer reviews as my older peers. And that's how it should be. Why? Because age has nothing to do with productivity, understanding or ability to come up with simple, elegant and maintainable designs.

You are a mercenary. That's the idea of a job. You do something, they pay you.
Agreed - Even now we're talking a about spending a ballpark $200-$500 for a VR headset, plus $1500 on a computer to run the software (that a lot of us already have). That's not a trivial amount of money, but it's hardly outside the reach of anyone in the developed world.

Consider that computers, microwaves and maybe even TV's started at tens of thousands of dollars - and that's before adjusting for inflation - and it's hard not to say it's already stupidly good value for money for an entirely new medium.
I'm sorry not everyone subscribes to your own personal views. Some people think it's funny, others don't. That's just life.
On paper the kids do the work, but in practice, its more "what can they get away with".

I made it to the state region levels as a kid with a lame project, but I did it all myself, and I remember walking the aisles thinking to myself, "I can probably win against that kid, but there's no way I can win against that kid's Dad who obviously did all the work"

The pinewood Derby in scouts kind of suffers from a similar problem, "who's dad has the best woodworking shop"

This might be a useful life lesson, in that on a very large scale the first thing you learn in business, politics, law is whats right or legal doesn't matter, its all in what you can get away with and who your parents are, and the top players tend to be better at getting away with things and won the genetic lottery. A meritocracy ... of crooks. And that's an education all in itself that will provide a lifetime of benefits once understood at an early age. So I'm not necessarily seeing a problem with education kids.
Meerkat makes it fairly clear that "everything that happens on Meerkat also happens on Twitter" – and the comments on a stream only go to Twitter as replies to the original invite tweet.

That's not 'automatically… to many users" but specifically to those viewing a thread, and only when individual users compose individual replies. It's not a clear violation of the quoted policy… if at all. And as you note, that's not the behavior Twitter has started.
Well, if you pay 10x for 10x more productivity you don't gain much, do you?.. Can't blame 'em for not bothering to look for a rarity for no gain.

In general HN is pretty centered, but there is always a slight bias, I don't complain about it, it is expected, there's no place without bias.

Those are the best examples of material design? Most of them are phone screenshots, higher than they're wide, on a blah background. The "material design" thing is supposed to be about dynamic effects. You click on things and they ripple. If the site let you go to the actual site or app being described, that would be more interesting. Or they showcased the material effects on their own site.

>Does company-mode completion not work for you?

In my experience, everything except syntax highlighting often doesn't work. But, anyway these are esoteric languages.

>What about selecting the android device to run an application on when you have multiple devices connected?

I don't use android, but you can create several run configurations, one for each device, and run them via shortcut. My configuration works like this: I set Ctrl+R to show popup menu with available options, then I type the name of the configuration and press enter.

Another action you probably aren't aware of is Navigate to action. It works in a way similar to M-x in emacs. See more here: https://www.jetbrains.com/idea/help/navigating-to-action.htm...
Removing restrictions on building would go a long way towards solving the problem IMO. You'd get uglier cities maybe, with taller buildings in more expensive areas, less parks, etc., but you'd get cities where more people could live, in terms of the amount of apartments per square mile as well as price (as the two ought to go hand in hand at least somewhat.)

I think that today's restrictions on building in many places are absolutely draconian, to the point of a chronic shortfall in the number of apartments built not just in city centers but in entire cities. I think that to some extent this is explained by a collusion of builders, property owners and bribed government officials (so corruption), and to some extent it's explained by the government liking to restrict building to preserve open space or what-not and not liking to do the work needed to plan and execute urban expansion at a decent rate (so laziness).
I agree. Something like a "Streams" tab in the app would be awesome. Once Twitter (most likely) rolls out this feature natively with its Persicope acquisition, it would make it a lot less spammy than the way Meerkat handles it. I want to be able to differentiate between tweets and live streams.
Don't forget doxxing, harassing, taking over subs, etc.
True, would be a learning experience to break out some basic sampling theory (do 10 bean seeds not 1) and break out the digital calipers to get some precision rather than "eh looks bigger" Or... the kitchen dietary scale. I can go to 1/10th of gram on mine and that might work.

Also a stealth observation is the hidden assumption that a negative or null result means the experiment was a failure.

Personally I've got a gut feeling that given fertilizer runoff problems, the beans sprouts grown in pond water would grow faster unless the pond was unimaginably pristine. A bored kid could settle this interesting discussion via experiment... better than being stuck with "water, tide, or pepsi, which do plants crave??"
See the footnote in the article (also noted multiple times above):

"We call them "useds" rather than "users" because Facebook is using them, not vice versa."
The reality of the human condition is that many people want to be "under" someone. Having complete freedom is both time consuming and exhausting. We already spend an inordinate amount of time making choices, it's nice to have many of them already made for us (or at least having our selection limited).
The problem is less with the mathematics, but efficient storage and retrieval of a large number of points (i.e. index won't fit in memory) from disk. Doing a search across a tree rendered to disk is really slow.

Even with mathematically sound storage trees as indexes, locations which are close in space could easily be split between two arms of the tree, making proximity searches quite expensive - you would have to traverse the entire tree to ensure that you do not miss data separated by a poor splitting plane.

There are a number of theoretically efficient solutions to this, but they are all become remarkably inefficient when you add in a hard drive.
Why your basal ganglia and wearables were made for each other
The "clean up Reddit" campaign is likely an effort to get Reddit to impose ideologically-driven authoritarian administration (more so than already exists). 4chan was subjected to a similar campaign and eventually yielded.

Reddit's traditional approach has, for the most part, been to err on the side of freedom of speech with minimal rules. Aside from the core rules, subreddit fiefdoms are allowed to manage their domains as moderators see fit.
Yeah, they need to be encouraged to ask questions about what happens in their lives. Stuff that they genuinely care about.

For example, the other day I was peeing and though, "Is there less splatter by aiming my pee above the water line or below the waterline?" If I was Richard Feynman, I'd probably actually do an experiment. Now that may not be allowed in a school fair, but it's an example of a trivial everyday thing that one can wonder about, and design an experiment about, yet maybe hasn't been established as fact (like plants like water).
I know this is absolutely the wrong place to complain about that, but I really really hope Facebook will stop having its videos as Flash-only.

It's such a "blast from the past" to see the "Flash plugin not installed" everytime someone shares a video.

Correct, but due to the Twitter mechanic where replies are shown in your feed if you are following both people (which was the case for me as the initial users are techies), it can still be a mess.

What you propose is similar to generating an integer in {0, 1, ..., 2^k - 1} and dividing by 2^k. This is not the same as drawing a uniformly random real number and rounding to the nearest floating-point number. The original link addresses exactly this problem.

This is an OK introduction to the issues of geospatial DBs (a meta meta article as it were) but two interesting (to me) points were made in passing:

> Most software engineers assume today, as I did a decade ago, that the design of scalable geospatial databases is a straightforward task.

You could substitute almost any computing topic for "geospatial databases" and still (sadly) have a perfectly reasonable sentence. Partially that is because our field is so new, and partially it's by simple naïveté which is occasionally powerful but mostly dangerous.

> Algorithms in computer science, with rare exception, leverage properties unique to one-dimensional scalar data models. In other words, data types you can abstractly represent as an integer.

Alas, this is painfully true, and the field of algorithms is so complex that the one-dimensional nature of our exploration is easy to overlook.

> it classified all NSFW subreddits as reddits dark side.

That's funny; I took the article seriously until it didn't classify, e.g., /r/ladybonersgw (male nudes mostly for a female audience) as "Reddit's dark side". Granted, they didn't list a thousand other NSFW subs, but to it still seemed like a pretty blatant omission and spin to only list NSFW subs with female nudes for a male audience. (See also Vaskivo's comment.)

And I needn't tell you what the majority of Redditors would say about an SRS mod speaking for Reddit.
I personally like the mess. If Reddit ever got "cleaned up" I don't think I would ever return.
In context, Armstrong is only concerned about 'security' from tampering/forgery in that statement. Confidentiality is not specifically ensured... but being indifferent as to the path/server which delivers your content may help the effectiveness of other strategies for obscuring your interest, such as routing your requests through mixes of trusted and untrusted relays.
That's a very sudden change. A lot of sites started using RC4 recently because it's immune to BEAST and Lucky13.
I like the present (older) output because it's absolutely unambiguous. If I have to read a textual description to understand whether it's a default argument, whether it takes an optional parameter, or how precisely it is used, it's less clear especially when the text is badly written. The current output is probably also perfectly suitable for parsing (by a program).
"Scrum/Agile (when properly used) has two main purposes... to better predict delivery of a particular technical capability (ie: when can I ship feature "foo" to customer "xyz"), and focus on keeping the product under development in a shippable state throughout the development process (ie: even though feature "foo" isn't done, I can still ship A, B, and C with minimal incremental work)."

A lot of people think that those are the core purposes of agile.... and that's part of the problem.

The real core purpose of agile is shortening the feedback loop. If you aren't shortening the feedback loop you are wasting your time.
You can turn that off, you know.

I have a lot of the same feelings about TED. The presenters come across as arrogant and usually misrepresent their project as ready to work, when in fact all they have is one dubious artifact.

"Oil Companies hate her: One TED presenter's idea will eliminate the world's oil usage."
"TED, with its airy promises, sounds a lot like a secular religion ... The TED style, with its promise of progress, is as manipulative as the orthodoxies it is intended to upset."

Many (though not all!) TED presentations showcase individuals who think highly of themselves explaining in digestible soundbites how they're going to make the world a better place, in front of live audiences who have a high opinion of themselves, for video distribution to online audiences who want to think highly of themselves.

It may not be a religion, but TED definitely has a cult-ish feel to it.

If you're using a proper cryptographically-secure hash, it almost certainly can't be collided.
Yes, of course.

If you use a tree hash, the side sending you content can even include compact proofs that what they're sending you is a legitimate part of a full-file with the desired final hash.

So for example, if receiving a 10GB file, you don't have to get all 10GB before learning any particular relayer is a dishonest node.

One thing they could do is create a separate domain/branding for subreddits that aren't squeaky clean so things look different on the surface.
loved the article. I strongly believe that when doing geospatial indices, it is quite important to up front establish the nature and distribution of your data.

Searching for a generic/theoretically all-encompassing solution is quite akin to looking for the perfect pub-sub system for all workloads. :)

My comment was related to lat/lon indexed data clustered around cities. If you know beforehand that you're going to deal with such a dataset (static or dynamic), one can pragmatically decide on some sort of by-convention partitioning (e.g. Partitioning by continent/region which will bring it down to in-memory indices not needing continuous disk access).

I love the non-euclidean bit in the piece you wrote. Anyone who has tried to do a k-nearest neighbor query east of New Zealand will appreciate that bit. :D
