I understand the point the article is trying to make, but its not realistic. Having worked with the Navy for a few years I know that the biggest use of airplanes is not air to air combat ( which is what this article is complaining about ) It is air to land bombing. So why are we complaining about making an air force that serves our needs rather then one that might be useful for some other task.

As a note he says this will be the "new mainstay of the air force" however we still have the F-22 as our air superiority fighter which is still believed to be better then anything out there, and indeed in their simulation the only limitation to the F-22 was there were too few of them. So this isn't really about America losing air superiority its about a few analysts not taking into account the entire mission of the three branches of the military. Maybe this plane doesn't stack up well against the F-16 or F-22, but It sure beats the Harrier and the F-18.
I use goog maps to plan hikes, to answer questions like "is this section of the trail kid / cub scout compatible"? Some trail sections are not. I can do a halfway good job with the satellite images and some topo knowledge but this new GOOG "streetview" trail UI is so close, yet so far from what I need.

What I need is something like a youtube of a high speed (maybe 30 mph equiv?) run down the trail.

I'm looking for stuff like hazards and issues. Like, oh, look, a swamp, either bug spray or forget it. Oh, look, a cliff, well thats very scenic but I'm not taking the kids there. Oh look, a whole field of poison ivy, best remember to corral the kids around there. Oh look, a blind corner and adjacent highway crossing, need to keep the kids under somewhat tighter control in that area. Oh look, picnic tables, guess where the kids are stopping to eat lunch?

Another obvious problem is the county I live in has at least 100 miles of trails either cross country or in parks, and the Mighty GOOG has ... the grand canyon. Well thats nice but I'm hiking a short segment of the ice age trail this saturday, not the grand canyon. Someday the streetview-like trail tech will be useful to me, but for years I suspect it'll be merely aspirational. It would be like having streetview for streets... but only in Mountain View.

But be careful when compressing. Never compress something secret together with something that an attacker can repeatedly influence, or you're possibly vulnerable to compressed length oracle attacks similar to CRIME.
Why are we still building manned fighter planes?
Exactly. I enjoyed the fairly well supported counter-arguments to the ideas. Inevitably it isn't going to be quite as good as it appears initially, and open debate is how consensus is reached, but he devalues the whole argument by laying into the person who brought it all up.

Whether or not the idea is valid is irrelevant - the fact that Elon Musk is proposing it does lend it some additional weight - with Space X and to a lesser extent Tesla, he has gone into an existing market, taken a step back, rethought things from the ground up, and re-written the book on how much it costs to do things.

I don't know if Hyperloop is as technically feasible and cost effective as it looks, I don't know if any government would have the courage to go in that direction, but I do know that it isn't going to get anywhere with good balanced debate on the technical merits of the proposed solution and ad hominem rubbish just gets in the way of that.
I don't think this is to replace the F16. The F22 replaces them. How do you think the F35 compares to the F18 ?

I wonder about the practical effect of this in the Real World(tm).

When cryptographers talk about a "break," they mean anything faster than brute force search. So a break of a 128-bit algorithm that allows key recovery in 2^115 is a "break," but still completely impractical.

But as Bruce Schnier says: "attacks only get better." So a break is a good reason to look for a fix or a better algorithm now before the crack widens.
catty is a big understatement for this article - there is some pretty radical thinking in there, particularly the part about entrepreneurs not deserving the spoils of their companies, because someone else would have done it if they hadn't. (key quote: "People get extremely rich for doing something first, even if in their absence their competitors would’ve done the same six months later.")

not sure what that has to do with elon musk, other than to try and put together a "nuclear" attack on his character, going after the moral foundation of his wealth in addition to the hyperloop idea. it's like the article is a communist critique wrapped in a technical evaluation.

away from the radical and bitter aspects of this critique, i appreciate the technical comments in here. i think it is vital to have a proper, public technical evaluation of the hyperloop, and he undermines his argument with the personal and philosophical. i would love to see a response to this critique from the hyperloop side.

i would agree that musk, having lobbed this hand grenade into public discourse, should follow-through on his idea to some extent - build a test bed and prove it can be done on a small scale. in my limited experience, if something is a really good idea, you try and pursue it for yourself, rather than hoping someone else will steal it from you.

Thanks. It was also down for my friend across town, who I checked with before posting.
You need every bit string to be maximally unpredictable a priori. EG, every bit string of length n is equally likely. This is not the same as having exactly equal numbers of 0s and 1s. That doesn't really even make sense, because with the constraint as mentioned, you can't ever transmit an odd length string. Also, if you are transmitting a bit string of length 2, knowing the first bit guarantees you know the second, which is low entropy (you only have one bit of entropy in a 2 bit message).

On the other hand, it is the case that most long bit strings sampled from a maximally entropic source have roughly the same number of 0s and 1s.
Quoting is nice. That's better than bash -x debug mode too.

Do you mean specifically why there is a dedicated Chinese following in particular, or just in general?

Ultimately, this article has one point but makes it about ten times. The point is that the F-35 led to the U.S. losing the 2008 war game. All of the quotes (particularly from Australian military officials) are about the failed 2008 war game.

It might seem like a valid point except that the war game deliberately crippled all the F-22s (the U.S. air superiority fighters) and instead pitched the F-35s (the U.S. jack-of-all trades jets) against Chinese air superiority fighters. It shouldn't be a surprise that a computer doesn't like that fight but it's a contrived and fairly silly situation since it's not really the F-35s job.

Not at all. Express is more like Rack than Rails. It provides routing and middleware setup... and that's pretty much it. It's a microframework designed to be minimal, so you are crticising its core design.

You should compare Rails/Django to full-fledged frameworks such as Geddy/Tower/Locomotive/Meteor/Compound... Many of these frameworks are built on top of Express, leveraging it just like Rails/Sinatra leverage Rack.

That's why you should never criticise what you don't know! :)

David, I'd recommend augmenting your instructions to include a passphrase. An SSH private key without a passphrase is extremely dangerous. Should someone gain access to your private key, they can use it without any additional information. This makes it extremely easy for them to impersonate you.

There is a utility called ssh-agent that will prevent you from having to enter your passphrase every time you use your key pair. Github has an excellent guide for OS X users:

https://help.github.com/articles/working-with-ssh-key-passph...

Linux users will use ssh-agent as well, and most distros start it by default.

Won't the air to ground bombing mission be done mostly by drones? Manned aircraft will be increasingly reserved for special operations and dirty little wars, which is pretty much the Marines' job description.

Also, the vertical takeoff capability will be mandatory for a hypothetical future war against a major power. Once the huge, lumbering aircraft carriers are sitting on the sea floor, they will be replaced by heavily armored battleships. In a major war, the only sea launched aircraft will be VTOLs.
Disclaimer: I haven't tried Leap Motion, yet.

Did I get this right? Leap Motion vs. Kinect:

- LM is smaller (significantly);

- LM is more accurate (significantly);
- LM has almost no real apps (mostly concept demos).

I find Leap Motion quite accurate. You will quickly get used to the convenience of gestures with BetterTouchTool, and wish you had it on computers which don't have Leap Motion.

Otherwise, The gestures used by apps is something that needs to be carefully crafted. For instance Touchless, the mouse replacement, simply doesn't cut it; you'll find yourself reaching out for the mouse/trackball/trackpad within the first 10 seconds.

The leap gets effected by strong light sources on the ceiling. You might want to use it facing downwards if that is an issue. Also, if you are wearing a watch or a ring, it might get confused with the reflection.

the F-35 is one of the largest wastes of government money that is publicly known. by the time the aircraft has all the bugs ironed out, it will have cost USD 1 tln and be easily destroyed by much cheaper drones. the entire contract should be converted into drone development, which will actually pay dividends.

trying to argue that we need the F-35 or that it will provide any kind of strategic military value is absurd.
> the biggest use of airplanes [...] is air to land bombing

But what happens to your bombers when you don't have air superiority?
I don't know about this case specifically, but it doesn't have to be recursive. English has a similar examples, such as Scotland, England, and Denmark. To take the first as an example, "Scot" is the demonym, and we add the suffix "-land" to make the placename. A demonym doesn't have to be based on the placename.
I think that the newer Kinect 2.0 will be able to take care of all these more sophisticated gestures. When compared to the Leapmotion it has much better range and its accuracy will improve now too.
Then those who prioritize it will take jobs where it is available.

By mandating it, an employer has to consider the possibility whenever they hire someone, and so salaries will be lower as a result. If the employee doesn't get pregnant and use the leave, their salary has been kept lower with no benefit to them.
Does anyone realistically believe you will go to war with China or Russia anymore?

Historically there have been military conflicts between superpowers. So I'd say its incumbent on those claiming we won't have wars to explain what's changed and why we won't have anymore major military conflicts.

Eleven-Year-Old Worth1000 Faces Shutdown
SpaceX is based on a fairly different principle, of taking proven designs from the past, updating them, and building them for less. For example SpaceX's Grasshopper VTVL is following in the footsteps of the 1990s McDonnell Douglas DC-X, not some kind of completely untested idea. He isn't taking a previously speculative technology idea, like a space elevator or something, and trying to build it.

An analog here would be if Musk had a proposal to take an existing, working mode of transit (at least working in prototype) and build it for less. But the current proposal is more like hard sci-fi: goes into enough depth to be back-of-the-envelope plausible, but no detailed engineering or working demonstration, and very hand-wavy cost estimates.
Bombing Quora.
Is there a story behind this, or is it just another "____ is down" post?
I don't believe this is accurate.

The F-16 is the "low" part of the "high/low" multirole fighter strategy. For the air force, the "high" jet is the F-15. The F-22 is predominantly designed for air superiority, and thus is most directly a replacement for the F-15C. Whether it really even replaces the F-15C is questionable, since the quantity produced is extremely small compared to the overall legacy fighter fleet.

The assumption is that gap will be filled by the F-35 and the F-16 will be replaced by the F-35.

there are first class functions, and closures work the way you would expect. Since it's statically typed and there are no generics, there's no way to implement something like a left fold; you'd have to implement it on a per-type basis, but you could certainly do that. I believe the answer you're looking for is "no", but Go's functions are nothing to sneeze at. http://jordanorelli.tumblr.com/post/42369331748/function-typ...

The USAF intends to replace the A-10 with this turkey, and it's an awful idea.

A-10: holds 1350 rounds of 30mm ammo. F-35: holds 180 rounds of smaller 25mm ammo internally, plus 220 rounds externally

A-10: 1.8 hour loiter time. F-35: Not listed, but as a high subsonic (stall speed) fighter, it's going to be shorter

A-10: Has titanium armor protecting the pilot & critical systems. F-35: Already overweight, no chance of any armor.

A-10: Can be field repaired. F-35: Because of stealth requirements, only the simplest of damage can be repaired in the field.

And then there's the price...

Check https://news.ycombinator.com/item?id=6211284 The design philosophy is pretty much the same as RoR's stack.

The idea in Node is that modules are simple, replaceable and composable: Express is a simple facade to Node's HTTP server (wrapping raw HTTP requests and providing a middleware framework) on which you can plug in new middleware (again, small modules) which do a single job well.

You can build full frameworks out of this system without the hurdle of these frameworks being monsters: just plug in the appropriate middleware for each relevant route and you're done (and, thanks to Connect/Express this plugin will work in every framework using Express as a building block).

There's nothing wrong with it, and it comes with many advantages.

So, to answer your question: yes. Node is not responsible of handling error conditions because that's not Node's job: it's part of userland. Node is just a simple IO engine, not a web server!

The full stack looks like this (similar to RoR's):

Node (Async IO) -> Express (Request facade) -> Connect (Middleware handling) -> Middleware and/or Framework -> Your app.

Not really, you'd have to add type assertions everywhere as go has neither generic functions nor user-defined generic types (only a handful of special-status types get to have type parameters, IIRC they're chans, arrays, slices and maps). That makes higher-order operations extremely cumbersome.

I'm also uncertain whether scalars (e.g. integral types) can be used through interface{}.
