It's not clear to me that paid-peering agreements will change at all based on this announcement. The FCC said previously that it doesn't see such agreements as a net neutrality issue.

I'm looking forward to day when instead of endlessly comparing languages against each other everyone just shuts up and builds stuff so that merit of your language choice can be judged by what can be built with it.
Probably not the best example anymore.
Stupid Tricks with Promoted Tweets
I think flying within centimeter distance of a building could present some additional technical and safety challenge (wind, avoiding people getting their fingers sawed off by rotor blades), but the legal hurdles will the biggest problem, I think.

There is little safe space to fly over in cities - you can't just start flying over roads and pavements, because if any malfunction happens, you'll be dropping a 10kg high-velocity brick at people and cars. You'll need at least specialized insurance for that, and I'm not sure if anyone gives this kind of thing.

Nice to know about it.

Sadly Oracle seems more keen in pushing the brain dead idea of Oracle Mobile Application Framework[0].

Regardless of the Google vs Oracle situation on Android, they could provide JIT and AOT compilers for the remaining mobile platforms, instead of leaving it in the hands of third parties.

I have turned to Qt/C++ and Xamarin for my hobby mobile development as cause of that.

You didn't come up with the idea of a heatmap. Their designs are different enough that I wouldn't consider it stealing. You're in the same space it looks like, of course there is going to be crossover.

JavaScript: Creating a Function with a Callback
Going back to the "breadth" recommendations, if someone wants a real appetizing sushi sampler of the breadth of Mathematics, I would highly recommend "The Joy of X" http://www.amazon.com/Joy-Guided-Tour-Math-Infinity/dp/05441...
It covers a number of topics in Mathematics and makes them really easy to follow for someone with no background in Maths. I especially liked how in a few pages I succinctly understood div, grad and curl from vector calculus.
For anyone wanting to start out on a full course meal of Mathematics this would make a very appetizing sampler.

> What becomes apparent if you dig into the numbers is that there's no money in building these networks, at least at scale--they are justified only when there's a money-making opportunity with respect to the content flowing through them.

It seems like the crux of your argument is that it costs something like $60/month to provide internet service and $20/month on top of that to provide TV service but they charge $50/month for each, so they wouldn't be profitable without the TV service. But who is setting these prices?

Is there some law that requires them to charge a money losing price for internet service and then make it up on TV service? Why don't they just charge a profit-making price for internet service?
Yeah is not like you're forced to use JavaScript right?

You're getting downvoted because you don't have an argument. All I see is rampant supposition and vitriol in your comment.

It is hard to understand an argument when none is presented. How is this fascism if the FCC has the power to do this already under existing law? How had the FCC "shunned the public from using radio waves and TV waves"? Keep in mind all countries manage radio transmissions because they have a vested interest in doing so. Shared mediums that everyone tries to use but cannot because of no management isn't much help. Think back to the LTE satellite internet company that had blocks right by satellite communication for GPS. You're saying its bad that we don't allow companies to run rampant over airwaves so that GPS no longer works? I hope not otherwise your argument is indeed shit and wrong.
Personally I find the confidence vs competence graph to reflect my feelings when learning things in general, although not necessarily for the same reasons. There's always a period of eager discovery followed by the stark realization of how far away mastery is and finally the gradual slow crawl toward success.

This is article actually has very little to do with any particular programming language or language comparisons. I like how it logically builds up to each of its conclusions which summed up are the following:

1. Variables should not be allowed to change their type.

2. Objects containing the same values should be equal by default.

3. Comparing objects of different types is a compile-time error.

4. Objects must always be initialized to a valid state. Not doing so is a compile-time error.

5. Once created, objects and collections must be immutable.

6. No nulls allowed.

7. Missing data or errors must be made explicit in the function signature.

I think the writer also provides a pretty practical definition of what it means for a program to be "reasonable". Really nice job!

EDIT: I pasted the wrong list as dsp1234 pointed out :)
Having taught many non-programmers to start their programming journey, this article rings very true.

The "cliff of confusion" he describes is a function of the Dunning-Kruger effect (http://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect), which indicates that you don't know how bad you are at something until you get better at it. As an educator, the challenge is to make that cliff as unscary as possible and chart a path through the "desert of despair" so that you're not pushing too much at one time.

On the other hand, as a self-learner it's really really hard to get past the point where you've learned enough to know how much you have yet to learn, or in terms of the article, when you look over the cliff and see how HUGE your journey is becoming.

To a large extent, the article is an advertisement (in more ways than one) for guided learning, expressed in a pretty clear way.

From the linked ArXiv paper:

"The first puzzling feature of the space expansion physics is that the Friedmann’s
equations Eq. (6, 5) in terms of the metric distance r(t) = S(t) · χ get the exact
Newtonian form:

...

"where M g (r) = ... is the gravitating mass of a ball with radius r(t).
So according to general relativity the dynamics of the whole universe is determined
by the exact Newtonian acceleration and Newtonian kinetic plus potential energy
conservation (here velocity of light c does not change the Newtonian character of
the equations)."

ARM’s trifecta: New CPU, GPU, and interconnect hardware on the way
For me, by far the hardest part was finding the time. Learning to code on nights and weekends, when you've spent your most productive and focused hours at your job, is a nightmare. It wasn't until I was actually hired as a dev that I started to hit a steep learning curve, and I attribute much of that to spending 50 of my best hours/week coding, rather than maybe 20 of my worst.
That's how I used to hitch lifts with trucks when doing bike messenger runs that took me down at the docks. Dumb and foolish I was.
If it's coupled, wouldn't it cross the boundary of the system, and then be included in normal entropy calculations as a flow across the boundary?

I can't remember the source, but I learned this in a management class in college about 10 years ago. It was a general statement about learning something new. You don't know what your don't know (so you are optimistic) -> You realize you know nothing (so you are negative) -> Then you get better with practice -> Mastery
So what if we build special trucks that have "shields" on the front that provide a spot for drones to hide while not unduly reducing drag?

Or what if the drones hide on the back of the truck instead of the top?
That's a good pointer, but that data is from HMI, not MDI (i.e., the paragraph of text is a bit off). The spectral lines are different, although this makes only a little difference in what you see.
You are indeed not forced to use JavaScript. Currently I can count PureScript, Elm, Scalajs, GHCJS, Opal, TypeScript, Amber Smtalltalk, and I don't know how many other languages that compile to JavaScript but are not JavaScript. So who's forcing you?
It appears that you copied the "F# does this" list, not the "How to make a language predictable" list. For instance, #6 on that list is "No nulls allowed" which is stronger than "Nulls are NOT allowed, in general".
this isn't an act of congress though. its regulations that the FCC has the authority to create and implement. if Wheeler says thats how it is, then that's how it is. regulations can be challenged at court but until that happens they will stick.

That isn't what "media conversion" means at all. It is the conversion from one medium to another: for example, from fiber optic (light) to coaxial (electric).

The use of reasonable here, is, I'd argue, unreasonable and done for the purpose of creating a click bait title.

> American media call Mugabe a dictator and call Cameroon's President a "chief of state", but both countries hold the same kind of elections.

"Chief of state" and "dictator" are orthogonal descriptions. "Chief of state" describes the ceremonial head of any state, whether or not they are actually the head of government, and whether or not they are elected, and whether or not they exercise dictatorial power.

"Dictator" refers to anyone exercising dictatorial power, whether or not they are also the chief of state (its possible, particularly, for a dictator to be head of government in a system with a separate head of government and chief of state, as might happen in a military junta in a state with a ceremonial monarch.)
Ride your bike every day
Exactly... just wondering if energy had to be conserved locally or globally?

Let me give you an example scenario:

Let's say (ignore the mechanism for now) that it's possible to send a small amount of information from point A to B. This information takes a tremendous amount of energy to generate at point A, and when it's received at point B it can be used to (somehow) unlock a tremendous release of energy. If you only looked at point B, it would look like you had an "over-unity device." But in reality the energy spewing out at point B is paid for at point A, and the information transfer by occurring at the speed of light does not violate causality.

Not claiming it's possible, just asking if it's expressly forbidden by fundamental physics or not.

(If it were possible it would of course open up all kinds of very amazing things like remotely powered space propulsion, a whole next level of power grid technology, or orbital solar power that actually worked, but I know of no effect that accomplishes anything like this so it's total sci-fi even if not forbidden by any known law.)

Edit: according to another response this likely is not possible. Oh well. :)

> If you are selling cars with the hoods welded shut and all systems permeated with DRM, are you making the world better, because, hey, cars are good?

My cellphone might as well be welded shut - because of system-on-a-chip design. I can't replace the GPU, the CPU, the memory, or any number of things I've repeatedly replaced on my desktops with my current lack of soldering skills or equipment. Is SOC design also immoral? Even as it enables access to the internet to an ever growing number of people, something some have been calling a human right?

But let us return to your analogy instead of playing analogy ping pong.

> If you are selling cars with the hoods welded shut and all systems permeated with DRM

Assuming the price remains around the same, I'd simply not buy that car because it's stupidly designed, and going to be a pain to maintain. I'd also not buy a car where I had to replace the engine block to replace the front headlights, no matter what percentage of it's software is GPLed, or how many of it's parts have 3D printer schematics available for me to replace them in my own basement. Neither choice is based on ethics.

I also think it's good we have government laws forcing car companies to make their maintenance documentation etc. available to 3rd party mechanics. Cars are expensive enough to maintain that society is well served by competition. And while proprietary systems aren't inherently immoral, unexpected predatory pricing based on vendor lock-in certainly can be a problem. I've seen the short end of that stick enough times to know it sucks. I think it's worth limiting what a car company can do to help avoid the circumstances that can even lead to that, even if some of the things we're prohibiting them from doing were perfectly ethical for them to do on their own.

But you'll be hard pressed to convince me it's a problem for your $3 copy of Canabalt. It doesn't need an oil change. With several games, I complain if 3rd parties figure out how it works - when multiplayer suddenly becomes plagued with aimhacks, wallhacks, maphacks, and other unfair competition.
Oh yeah, that's true. Well, consider me convinced that it was appeal fodder.
Even if you compile to JavaScript from another language, you'll end up eventually debugging the compiled JavaScript in some cases. Painful times debugging GWT code compiled to JavaScript suggest that the development tools aren't sufficient to avoid the need to do so.

In comparison if you write Objective C for iOS, you can debug the Objective C, as opposed to needing to debug in the compiled assembler.
That's all artificial. You don't throw out facts, hide your head in the sand, if you are seeking truth.
Oh, I do simplify a lot and hide myself under "Fundamental physics". You are absolutely right to call me out on that. :-) But lets think about one of the examples that you brought up:

> - Black hole information paradox

This is indeed a big question, but I would discard this in what I wrote since: What is the experiment here? There is theoretical evidence for the Black hole entropy, but even if we could create black holes, which has so far not been accomplished by the LHC, how would you measure it? It is a bit more difficult than a gas where you could deform it and measure temperature etc.

So this I would discard because I was considering discrepancies between theory and experiments.

> - Mechanism for...

some of these I would exclude in what I wrote because they might be explained by current theories, but it is just not known how exactly. Take ultra high energy cosmic rays, there are Shock-front acceleration mechanisms, Supernovae explosions etc that are candidates, and if I understand the formation of that unsolved problem correctly it is to among these candidates identify the correct one or the main one (or if the candidate is not among the ones we know now, find a new one and explain it).
This wasn't about persuading, but about them not being jerks and making life easier for those who develop cross platform applications like games. I'm sure many developers would appreciate using portable API.
Nicely done. Illustrates the mechanisms great.
I had a couple of things in mind. One was means. That you can solve a problem by restating another way, in a way that it's almost indistinguishable from the original. e.g. solving a problem in linear algebra that also solves a problem in graph theory. solving a group theoretic problem that gives you an answer in topology. solving a problem using category theory that gives you a combinatorial answer, using quaternion algebra to compute a rotation, etc.

The other thing is that in Math you are often dealing with the same question but with very different objects or variable types. The same question where your numbers could be real or complex, integers or finite fields, vector spaces or topological spaces, etc., change what the "correct" answer to the question might be.

http://www.fourmilab.ch/etexts/einstein/E_mc2/www/ says the original, translated from German, was the text "If a body gives off the energy L in the form of radiation, its mass diminishes by L/c²", that is, m = L / c². L was used for energy at that time, instead of E.

There is no square root. If you include the momentum term it's E²/c² - p² = m²c², which solving for E gives a square root, leading to http://en.wikipedia.org/wiki/Dirac_equation .
