> This is why I bought a DK2, I believe VR IDE's are going to be a thing, and they're going to be great. The fonts aren't very crisp in this video, but once we get some nice editors in there it's going to rock

To a degree. But I when I work I have two WQHD monitors (2560x1440) with one turned on its side so I have one text editor with a vertical resolution of 2560. When ever I work on a laptop, even an HD laptop, I miss this setup so much as it feels like I am drinking through a straw.

Because of this I am unsure if VR, which is going to be much less than what I am working with now, is going to be a serious replacement.

A couple of factual issues: most planes fly on Jet-A aka Kerosine which is actually closer to diesel than to gasoline.

You're talking about 'avgas' which is used for piston engined planes, the turbines typically run on cheaper fuel (they can be run on just about anything but typically you'd run them on Jet-A rather than on single malt scotch).

Second, plutonium 'batteries' (you mean a thermoelectric generator powered by nuclear decay) aka an RTG is not feasible for aircraft due to the weight of the shielding that such a solution would require as well as the risks associated with flying such a device (it can crash!), not to mention the proliferation headaches and waste disposal issues.

So even though they are used in space they have little or no chance to ever see deployment in commercial aviation or to power drones.

my point is ,you dont write raw tcp text commands when you do an http request in Go(well you can,but what's the point when... )...There is an abstraction layer,you deal with "objects",not HTTP text commands directly.

I dont see why it's nice to have an abstraction for HTTP but as soon as it comes to RDBMSs, string commands should be the way to go...

Not only the developing world - simply youngsters who will be entering the workforce soon. There's going to be a lot of them (what with programming being the new goto "future proof" profession) and it will drive down pay rates like never before, in my opinion.
That's preposterous. $130k gets you quite a bit in SV, even a pretty nice 1BR apartment in SF if you want it. Yes, it's more expensive to live here than most other places in the US, but saying $130k isn't enough or is even marginal or crappy is ridiculous.

$75k in Texas probably does go farther, but that's not really comparing apples to apples.

Is it now time for this ancient dichotomy to be embraced by computer science?

For the sake of argument, if the principles of OOP are: dynamic dispatch; abstraction; subtype polymorphism; and inheritance, what might be the equivalent for Subject-Orientated Programming ?

In my view, a charateristic of SOP must be that data is personal and unique. Every single usage of data specifies a new unique identifier. To read is to interpret: is to record a new ID. Here, identity (x==y) gets broken; so another operator is needed (x~=y).
Looked it up and that show is set in 1983 so it does seem rather implausible but not impossible of course. :)

Why the U.S. Military Is into Bee Brain Surgery
Speaking from a US centric view, the only way to protect America is to control the disease at it's source. If you prevent air travel, you make it difficult, if not possible to control the disease.

By putting on travel restrictions, you will lose control of the disease and jeopardize the United States.

So, in effect, if you wanted to spread the disease and put the United States in grave danger, you would put travel restrictions in place.

He might be suffering deep depression right now. I have heard about two cases of people cutting off contact with someone they worked for. It turned out that both of them were having depression at the time, due to the continuous frustration they had during the communication with their respective boss. One of the men quietly went back to his hometown in the end.
> Stored procedures, triggers and views are banned.

So... NoSQL? I'm only half-joking -- I find it strange how people will use an SQL DBMS, and yet choose not to use the main features. Model, Normalize/refactor, then apply views/triggers/stored procedures to present a simple "API" (or maybe just "view") of your datamodel to the application?

If you don't use the DBMS for modelling the data, do you really need it for storing your data (obviously, one valid answer is "no" -- see "NoSQL-movement", Object DMBS, Document DBs etc...).

I don't know enough bout meteorite, but is it possible that the water nearby is contained by the meteorite and is toxic? (Or at least that is was toxic for a time after the meteorite fall, and nobody dare to retry later.)
"Well, there is Sitting Zen (zazen, meditation), there is Walking Zen. Oh, and then, of course, especially in the West, there is Talking Zen. No good."

Many Zen practitioners have received their first contact with zen trough Alan Watts. He was really good writer. But eventually you must realize that he was philosopher, alcoholic and religions scholar who looked Zen from the outside. Talking and thinking about Zen is like talking and thinking about physical exercise. Philosophical thinking about koan is like treating bench press as a philosophical problem. You can't lift it with your toughs.
I'm happy with a single 24" monitor with one split screen.

There is a virtual space 10 times bigger than 27" monitor, but it's only in my head, and I have no need to see it in 3D space.

But that's because I work in this space every day, I know all filenames by memory, I always know exactly where I wanna go, and type cmd+t followed by filename automatically.

This VR idea is like flying through places, but you don't need that if you can teleport.

I can't imagine this being useful in day-to-day programming, but definitely would use it for discovering an unknown project.

Show HN: PixelTool – a tool for overlaying designs for pixel perfect front-end
I'm confused; I don't see how the randomness is really important here. I modified the code such that the expected value of each coefficient is a function of the term's degree:

randomPoly[n_, x_] := x^Range[0, n].Table[RandomReal[{1, i}], {i, n + 1}]

With this bias (or any of the various of biases I've tried), the result is exactly the same.

I guess my observation is 'symmetry' of the coefficients has nothing to do with the 'symmetry' of the roots.
It would be great to have a text input device which allows to move freely, something like the key glove: http://www.keyglove.net
Because quadcopters are naturally unstable, so you need complex electronics(and sensors and electric motors) to control it.

You can make helicopters very stable just with weights in the rotor, like any RC fan knows.

Until very recently the inertial motion control complex elements were very expensive.

Accelerometers in cars and gyros in smartphones later had made those sensors inexpensive. The iPhone was released in 2007, that was 7 years ago.

Every air device carries gyros inside, but for controlling the plane they had to give you a digital signal, it is not enough with the artificial horizon sphere.

The simple helicopter design has been mass produced for decades(and wars like Vietnam subsidized them more), and it is well tested and reliable. Any new design has to compete in price and will have to iron lots of bugs at first.

The second most important reason is that you need to use electric motors as normal heat engines could not respond as fast as needed.

So in order to make a quadcopter you need to generate electricity onboard, which means a big hybrid engine.

I see quadcopters as the future, but in order to compete in price, they will have to evolve from small UAVs.

This is the heuristic explanation given in the answer just below the top one, so you are definitely right there.

I also think it's important to mention that the roots ax^300-b have magnitude (b/a)^(1/300), which is much closer to 1 than b/a, which is why the magnitudes of a and b don't matter very much.

The text promotes keeping an open mind and to be humble. Often, The exception to a common rule are dismissed as minor and without effect which allows us to keep our certainties. The light example in this context, is well choosen : it is fundamental, factual and therefore cannot be dismissed easily. The scientific aspect is secondary to those advantages.
If it is self-referential, it indeed is. The parent comment (this comment's grandparent) is not noise. As with almost any question involving the term "random", the answer depends on what you mean by that term.

Oftentimes, one can leave that implicit because there is a commonly understood distribution. For example, "pick a number between 1 and n" typically implicitly assumes a discrete uniform distribution, "pick a number between 0 and 1" a continuous uniform distribution.

For polynomials of degree n, whether picking a random polynomial by randomly selecting its coefficients is more obvious than doing zo by randomly selecting its zeroes depends on what you pick as the natural representation of a polynomial.

At the moment, the effective vertical resolution is about 3240p, and the horizontal I'd guess would be around 6000p. And that's just the technology preview, I don't see how you think VR is going to be less than your setup, when it's already more..
Are you sure? I used to live in MV 5 years ago. Was in a decent apartment 20 minute walk from the Google campus. The rent used to be around 1700. I checked the price for the same apartment complex a few days ago on a lark ... over 3K! 2 bedroom apartments in the same complex range from 3500 to 5K. I assure you ... Texas is cheaper than this.
While there's a lot of talk here about the future of IDEs, difficulties with current hardware and other challenges, I'd like to take a moment to talk about what's actually in the video.

This fills me with almost childish glee. This is a virtual reality, where you can pop up a "god window" and create/mess with a world around you. Even just what's in the video, making some cubes move and change colour is wonderful. It's fun!

Remember the early bits of amazement at programming? Where you could make the computer say your name or draw a square? How much cooler would that be in VR?
Same reason why many companies (including probably Google) outsources landscaping work even though there's work to be done every year around. The subcontracted companies have foreman and managers who are much better equipped to train people in janitorial, cleaning, and landscaping work than Google.

Whatever the motive, I applaud the move.
> This VR idea is like flying through places, but you don't need that if you can teleport.

It's not, didn't you watch the video? You don't fly, you sit still. Even if you would want to move your virtual presence, I'll guarantee you that the computer can teleport you faster than your brain can, not that I think that would be comfortable..

Anyway, I'm glad that you're happy, so by all means stay happy.

Interesting to consider where this might be headed. The merging of app and web history in Android L's task switcher points to some kind of unification of native apps and the web in future versions of Android.

Google seems hesitant to adopt newer features of Java after their tussles with Oracle and Apple has raised the bar with Swift, even if it's in a rough state. My semi-educated guess is that Google has big plans for Dart, the Dart VM, and the next generation of Android.
For private/small projects free BitBucket is enough. For larger projects I have used self-hosted Gitlab which was running very well on relatively low spec server.
Avoiding lawsuits for racial discrimination.
“Writing is pretty isolated,” Barry said. “I enjoy the action. I like to fight.” // More coders should feel this way when it comes to issues about which they're passionate. In other words, more of us should consider becoming hacktivists -- at least on the side. As hacktivists, a wise first step towards making a difference is to treat political science as continuing education. Yes, articles like this should pique your interest. Read them. But also pick up some books and get serious.

To that end, as an alternative to "Rising Tide" by John Barry (from the linked article): I highly recommend reading (as did Aaron Swartz)[0][1] "The Power Broker: Robert Moses and the Fall of New York". It is a brilliant, Pulitzer-prize-winning case study of the forces at play in broken/corrupt governments (and how opaque the processes which formulate and execute the policies of governance truly are).

In Aaron's own words:
"For nearly forty years, Robert Moses controlled New York. Controlled it almost absolutely, overruling every mayor, governor, president, and public pressure group. He did it all without anyone ever knowing: the press, when it did cover him, covered him only in the most glowing, reverent terms. He did it all without winning a single election: the two times he did dare run for office, he was defeated so soundly as to become a joke.

"_The Power Broker_ is the story of how our "democracy" really works. How men gain power and how it corrupts them. How cities get built and how real people suffer for it. How we became a nation desperately dependent on the car."

I will add that Robert Moses was the pioneer of eminent domain (a massive blow to the philosophical underpinnings of property rights in the USA) and modern public authorities (highly insular entities which are hybrids bodies corporate & politic -- receiving money from the public with zero effective accountability to taxpayers -- hard to summarize implications, but they have been enormous).

I had a gitlab instance on one of my computers that is online 24/7. It is a good solution, but my system was compromised by exploiting ruby / gitshell . Also it took way too much system resources to operate.

I said "show me the hordes". I can come up with any number of anecdotes myself. But show me the numbers that say that it is a safer bet to stay in academia or in a technical job and file patents than, say, go to Wall Street.

I know lots and lots of people who have patents. Some of them have many patents. I know exactly zero people who have gotten rich off of their patents. I know a few people who have gotten bonuses for their patents. But nothing that would even buy a decent car. And these people are anything from independent practitioners to employees at large companies whose products you use every day.

Convince me that this is more than a mere anecdotes about lottery winners.
The problem is much bigger than the specific process used or the findings in the verification. If you look at what they found in the code in the short inspection, you would shiver. For example, vote secrecy was protected by storing votes in a shuffled order, where the shuffle was determined with the random seed srand(time(null)).

But still, the problem is the principle: the system is the only source of truth, and if there is fraud, or a bug, that changes votes, it is undetectable and impossible to prove. TO have the fate of 200M people depend on such premise is absurd.

The electronic system must change, but this will only happen if there is awareness and sound technical discussion by the population.

For distributed systems key value stores are the infrastructure that runs a lot of the larger companies like Facebook, Yahoo, Google, Reddit, etc.

Facebook is famous for cassandra for example.

They are tons of uses for them. A lot of them are evented and stored data analysis.

What's tough and utterly ignored by this article is that it's not just the lobbyists who oppose you, it's ordinary people. There is a sincere and deep seated belief that it's morally objectionable to ask companies to answer for their actions in a court of law, that there are no alternatives to destroying the environment, and that such lawsuits threaten the existence of economies like that in Lousiana.

That's why these politicians can take actions in favor of the industry with impunity.

> Jones figured there would be a period of quiescence while the industry decided how to respond. Within hours, Jindal, who was in Aspen, Colo., at a meeting of the Republican Governors Association, released a statement. “This is nothing but a windfall for a handful of trial lawyers,” Jindal said, arguing that the suit came “at the expense of our coast and thousands of hardworking Louisianians who help fuel America by working in the energy industry.”

85% of people in Louisiana buy this stuff up. They'll buy it up until all the oil is gone, and when the companies leave they'll have no jobs and their state will be a wasteland unfit for any other sort of economy.

To be fair, it's not just Louisiana. During the last Presidential election, Obama and Romney literally fought during one debate to show who was more pro-coal. There's no point in doing that if you're just after campaign donations--the coal companies can do their own advertising. No, such theatrics are to get votes in places like West Virginia, Pennsylvania, southeastern Illinois, etc.
