While rewriting things in different language is fun (and fun is a great reason to do stuff), the speed of delivering what is ostensibly static content is a solved problem. This was completely unnecessary. Bake the blog post into static HTML and tune up Nginx to shove it down the wires as fast as possible. Stick it on an CDN somewhere if it's important. Then move on to a problem that doesn't already have an optimal solution, and share the solution if you're nice. That's how everything should be done.
The things the mention sound to me just like the standard things cryptographer worry about on a daily basis. I am not sure there is anything new there.

"Lockheed’s F-117 stealth fighter was developed in a breakneck 30 months by a close-knit team of 50 engineers led by an experienced fighter designer named Alan Brown and overseen by seven government employees."

No, it's more about the fact we've had some interesting ideas in history before. Some were even built in small scale, my personal favourite is one of Brunel's:

The Leap won't be a "real input device" until you can get your hands out of the flat orientation. At this point, it is a toy.

I think the article is good coverage of the state of the device.
I've used this philosophy for years - I see that it really can set candidates apart.
I'm not sure why you wouldn't cache anything. It doesn't matter if x is faster than y. If both were cached the difference might be milliseconds and in the real world that is what will happen.
I think there is what the Pentagon "wants" to do, and what will naturally evolve despite whatever direction they throw their money.

Drones will probably get good enough to do most air to ground, at 1/10 or 1/100th the cost or whatever figure is being thrown around. Maybe even air-air, although I don't really think anyone has seriously tried this yet.

Manned aircraft in the meanwhile will pad a a large number of Pentagon manager's retirements and kid's college educations...

Thinking big? No, they are not thinking big yet. The world has become extremely globalized and still actions like this are stuck in a limited perspective of a single nation. Come back when they are doing strikes hitting a large part of earth. Then they will be thinking big.

Unions will eventually have to internationalize or die in the face of globalization.
My favorite discovery is how to efficiently do RPC style calls in BASH. Let's say you have some functions and variables you want to execute on a remote server. Just do the following:

ssh remotehost "
$(declare -p var1 var2 var3)
$(declare -f func1 func2 remotemain)
remotemain"

In this example, var1, var2, var3 and func1, func2 are support variables/functions for the function "remotemain". This pushes all those to the remote side, then calls remotemain.

Startup Engineering: Regulation, Disruption, and the Technologies of 2013
What's wrong with this part?

> Tesla’s train energy consumption numbers do not pass a sanity check, which suggests either reckless disregard for the research or fraud. I wouldn’t put either past Musk: the lack of references is consistent with the former, and the fact that Musk’s current primary endeavor is a car company is consistent with the latter

If the blog post's claims are correct - and the numbers in it seem to have a much more solid basis in fact than anything Elon Musk's come up with - then even a simple back-of-the-envelope calculation should've been enough to show his power consumption figures for high-speed rail are impossibly high. The trains are simply incapable of using that much power.
You wouldn't see this in an XBox game though - the XBox SDK doesn't support it.
I neither speak nor write nor read Chinese, but someone explained to me that those names are simply rough phonetic approximations. They decided to go with words that weren't offensive, but sound like the country's names, because that's the polite thing to do.

I'd love for someone who actually knows what they're talking about to chime in, though!

> This is obvious from the kind of nitpicking that goes on (no references! 4.37 m/s^2 is the maximum motion sickness possible because an accredited expert proposed it; I've never seen 4.9 m/s^2, but it's surely a barf comet!)

This isn't nitpicking. Dealing with the acceleration around curves is going to be a problem for any transit system and at higher speeds it becomes a bigger problem. Unlike bathrooms, this is going to be intrinsic to any system that carries human beings. As the author points out that the hyperloop proposal has significantly higher acceleration than any other high-speed system that he knows about.

So, how did the hyperloop designers decide that 4.9 m/s^2 would be safe? Did they find some study which tested this level of acceleration on average people? Did they conduct their own study which overturned conventional wisdom? Did they look at the research which led to the 4.37 m/s^2 figure and determine that it was fatally flawed? This is a critical issue and if the designers don't explain themselves, then it's fair to assume they made it up.

The hyperloop proposal contains innovative elements (air suspension in evacuated tubes) and elements which are essentially common with many other transit systems (viaducts, human passengers). The designers deserve credit for the former, but they can't sweep the details of the latter under the rug. The point of references is not stylistic and not to name-check previous work. The point is that when you're doing something, which has had lots of previous research, you either use that research to justify your claims or you explain why yours will be different.

> The really interesting, constructive questions: does this low-pressure air cushion thing really work? what are some factors that we need to explore to determine its true efficiency?

Those are interesting questions and if Musk had proposed just the air cushion technology, then that's all we would be talking about. People would build test pieces to validate the technology and then go looking for applications. Instead, Musk choose to also include a specific proposal for a replacement for the LA-SF high-speed rail line and to estimate the costs at a tenth as much. That's what got the most media attention and so that's the aspect the OP chose to criticize.

BTW, you seem to be implying that the OP is a civil engineer or a transportation engineer with an axe to grind, but he's just an amateur and if you look at his other posts you'll see that he has a lot of concerns for reducing the costs of infrastructure projects.
The expected benefit for those that don't use the leave themselves is a more stable and healthy society due to better child care and stronger social/family bonds. Overall lower (net) salaries is a trade-off that most societies in the world are willing to make. Mandating it is a means of mitigating the tragedy of the commons - people thinking that there is no benefit to them at all when they don't get the benefit directly.
Interesting. Unfortunately I did not make it past year one Chinese in university, so I do not remember enough. If I had known, I would go find out if he contributes a lot on the Study Golang BBS.
One punchline at the end of the article seems to implicitly agree on drones:

> Ward said any future warplane should have clear and narrow requirements, as opposed to the F-35's broad, incompatible guidelines. Development timelines should be fast, budgets should be inexpensive, the overall concept should be simple and hardware should be as tiny as possible.

The one way we have today to accomplish all those goals together is unmanned aircraft. Simple because no life safety systems. Tiny because no human factors (displays, radios, windscreens). Cheap because no need to get every plane home safe (mission success largely determined by delivery of sufficient quantity of planes to the theatre).

I remember the latency being around 4-15ms depending on the number of hands in the frame. That's very low, but if you compared with 1-2ms latency it would be noticeable. Applications can add additional latency on top of that.
Much smaller scale, but in 1870 a demonstration pneumatic tube transit system was made in New York:

Imagine using your hand as a mouse. Just move it around on the desk next to your keyboard, tap the surface of the desk with a finger to click, you've automatically got five buttons - one for each finger, etc. I guess that would be kind of like a "virtual" trackpad plus if you need to go 3d, lift your hand off the desk.

I have an experience similar to OP's. I had been user of four platforms (Blackberry, iOS, Android, Windows Phone 8) and all of them have benefits and caveats.

I only differ with OP in the fact that he pretty much blames device makers in the android case, and I think that the problem is more than just the device, at least that was the case before Ice cream sandwich, and at that point I was just done with Android.
Cable companies do offer a low cost bare bones option. It is called "basic cable." It's a few bucks a month (around 10-15ish) and when I had it, it was about the first 15-20 or so channels.

Looks like someone rediscovers Prototype.js. jQuery does not extends DOM because it does not work. Library before jQuery choose extending the DOM approach and chaos happens, that's why jQuery got popular.

In the end the author said "DOM extension is no longer to be feared". So what's the argument when you read the linked article? "Just choose non-conflicting name!" Really? That's your suggestion?
Breaking Bad, Mad Men photographer warns that digital cameras can be 'too clear'
You won't see A2A drones for at least another decade. In a non-contested environment, dropping Hellfire missiles is easy from a slow moving drone like a Predator. But this won't occur against a peer enemy. It's too easy to shoot them down.

As to A2A, there are far too many obstacles for this happening soon.

Plus, there's the whole notion that in a conflict against a peer opponent, that we'll somehow be able to manage the command and control of drones; that the opponent won't be able to disrupt our satcoms and other control channels. This notion is a bit naive. There will be a place for a man in the cockpit for quite a while.
Well, that's 1-2 miles per minute if you don't run the A/C continuously. If you were to keep the cabin at a climate controlled temperature, the Leaf normally estimates ~10% reduction in range. I'm not sure how true that is because I've never needed to do it. A couple 1-minute blasts is plenty to get me home comfortably.

I do agree that the Leaf could benefit from more range, of course. Although it should be able to handle your commute in the summer without an extra charge. In the winter it would be a stretch, especially with the heater running.

The Tesla is an awesome car, if you can afford it.
Before steam engines became / turned out to be practical to place in a moving vehicle, there were railroads powered by pneumatic tubes so the heavy machinery could be stationary. The pneumatic tube was between the rails and it had a leather seam sealed slit all the way. The "locomotive" was attached to the piston in the tube with a vane going through the slit.

The magnet cleverly eliminates that.
So we throw away all scripting? No more Google Maps? Doesn't sound very realistic to me.
Your second mistake might be assuming that rationality, logicality and common sense are one and the same.

Interesting, the mail office actually used this for some time, but to quote the article:

"The Edinburgh Evening News reported in 1876 that the trucks containing the parcels continually stuck in the tunnels, and this was the reason for the failure of the company."
You need to add weight, and wing loading area, and what G's the plane is rated at. These are key variables.

The F-16's max speed is far greater than Mach 1.2, I thought, or at least it used to be before they added on weight to the thing.

It's also well known that the designers optimized the F-16's ability to quickly lose/gain kinetic energy, what they call "dump and pump". This is hard to quantify.

Some of the "nextgen" fighter capabilities widely touted are "supercruising" (i.e. supersonic flight without afterburner) and thrust vectoring, i.e. changing directions quickly by nozzling engine thrust off center. Amusing, the original YF-16A prototype could supercruise, and execute a "buttonhook turn" maneuver, without the fancy 21st century engines.

Imagine what the F-22's P&W F119 engine could do in a modernized F-16 airframe....

NYC also had a pneumatic tube mail network: http://untappedcities.com/2013/03/15/nycs-pneumatic-tube-mai...

It ran until 1953. Paris also had one. It's a worthwhile read.
To their credit, the F-117 also wasn't a multirole fighter, was built in low quantities, wasn't planned for export uses, and was relatively quickly retired. It's a one-trick pony designed to sneak in, drop a precision bomb, and get out.

People have been saying the demise of the carrier is upon us for 5 decades. Yet nothing offers the flexibility and power projection capabilities of a CVBG. And guess what submariners call "heavily armored battleships?" Targets...

And if you think CVNs are expensive, you should research how much retrofitting an Iowa Class with a STOVL flight deck would cost. And then factor in manning costs for a ship that needs close to 5000 sailors.

The biggest reason why Python 3 is/was seeing such late adoption is purely because web frameworks/libraries were not migrated to Python 3. Goes on to tell how many people use Python for what purposes, that absence of a domain of frameworks/libraries slows down the adoption of the language itself for years.

Of course Python is used for scripting purposes. But that amount of code is no where close the web code that is written in Python. It all depends how much code in ratio is written for what purposes and not the total amount of code written for that purposes.

Python's glory days came with web frameworks and continue to be the reason for its fame and wide spread adoption.

I will take Python seriously if it offers the same capabilities as Perl at least on the command line.

Python is a awesome general purpose language. But so far as scripting is concerned it is still no match to Perl

Ask HN: Where/how do I learn very basic API skills?
I am learning to build software since this January. Now I know the very basics of CSS+HTML, some Javascript and C#/.NET. Enough to create from scratch, publish and sell a very simple SaaS (in my case, the first "S" could stand for "spreadsheet", so simple is my service).

I learned with Codecademy, Treehouse and try and error with the enormous aid of Stack Overflow. But now I want to create a very simple site using a API. And I can't find the right place to learn it. I mean, even Codecademy have this thread, but everywhere all API learning resources look aimed at more advanced developers.

There is no basic tutorial on how to do it. I mean, very, very basic tutorial, telling me how to establish the connection, where to write my code with the GET/POST/PUT/DELETE, what the hell RESTful means and if this is something relevant to my basic code or just a theoretical base if you to go further down the road.

So I wonder, do I have to be a proper javascript developer to even start learning API? I am not a proper C#/.NET for sure, and still could build a simple logic with try and error. I guessed I could do the same with API, am I wrong?

PS: I already have a project in mind, I want to build a tool using the API of HNSearch: https://www.hnsearch.com/api So I want to learn generic API development, not a specific one.
The assumption with the F-35 seems to be that technology (better sensors & automation) will overcome performance & armament disparities. This is not a new assumption in the air superiority game, but I don't think history's been kind to it to this point.
I'm really uncertain about node being judged more "mature".

Being developed by Thompson and Pike makes you gain something like 30 years of "maturity". Plus, running in production in the Google infrastructure is far more of a proof of maturity than running the chat service of every hackathon project for 2 years.

I frequently find Nissan Leafs driving very slowly (45 mph in the middle lane on the freeway, 30 mph in a 45 zone in the left lane).

And they accelerate very slowly from traffic lights, clogging traffic behind them.

Does the car itself suck or is it the drivers or is it a UI bug in the car that encourages people to drive it like that.
