Game_Ender··on GitHub monoculture
If you are logged in their is a search bar in the upper right hand corner. It has the same problem as your search thing.
Game_Ender··on Red Hat Enterprise Linux 7 Beta
That is a very awesome tool, I am really wondering why I have not seen it before.
Game_Ender··on Britain’s Ministry of Nudges
It really makes you question the structure that puts in place the original polices this group "nudges". There needs to be an incentive structure in the government itself, that encourages every department to improve how they function continuously. You shouldn't have to create a special department that focus on one tiny portion of the government at once for improvement.
Game_Ender··on Capnproto-rust vs. C++
That would be quite useful. Otherwise it's very hard to tease apart the differences between optimization back ends of GCC and LLVM vs the Rust and C++ front ends. I feel like I have seen benchmarks showing differences around 5-20% between LLVM and GCC in speed, so the it will have an effect.
Game_Ender··on Do “Shitty” Work
I always thought the idea was that the LTV is in getting a lot of users and you do that by making as good an impression as possible on your first users. Even if you are spend several times what your initial users bring in supporting them, if that creates enough traction to get a lot of users down the line you come out ahead.
Game_Ender··on The E-Cigarette Industry, Waiting to Exhale
Even with regulation you still have to trust the companies making products. Most regulations do not require statistically significant independent sampling of every batch of product people consume. With such independent testing, you are going to have to trust the producer.
Game_Ender··on The Economist Who Thinks Owning a Home Is a Terrible Investment
Rent is an all-inclusive expense usually, while a mortgage is not. Rent covers maintenance, taxes, cost of future renovations, and you usually don't have high transactions in getting or leaving an apartment. So you can't directly compare mortgages and rent amounts.

I sure hope that is a They Live [0] reference.

Game_Ender··on Aerospace Company Develops Drone That Can Fly Continuously For 5 Years
So this looks pretty cool, and their marketing department already coined the term "atmospheric orbit", but their aircraft currently looks like vaporware. All of their videos are pre-rendered and the short clip in the article is too [0] small to be the aircraft they are trying to sell.

It also raises some flags when their quotes are from Senators and their "social proof" logos aren't customers they are supplies of the components they are using.

Game_Ender··on Time-lock encryption
Yeah every body has $4 million in hard drives just sitting around. At 1TB each that is a 40 peta-byte array, that is still huge in this day an age.
Game_Ender··on Boston Dynamics Unleashes Wildcat, the Sprinting Quadruped Robot
You should take a look at the research [0] people are doing using the little dog [1]. They are creating some very interesting planning algorithms for unstructured terrain like that.

I have you heard of LS3 [0]? It's another DARPA project designed to bring autonomy to platforms like this. The controls work Boston Dynamics doing is very innovative.

Google is doing great work, but it's much more on the refinement and engineering side. These guys all worked on the DARPA grand/urban challenge and putting in time to make the base level tech robust.

Game_Ender··on Boston Dynamics Unleashes Wildcat, the Sprinting Quadruped Robot
DARPA is funding the early development of technology they think will some day be useful to the military. Similar to how the DARPA Grand/Urban challenges helped plant the seed for fully autonomous ground vehicles.

So this specific robot is not meant to kill humans, but a robot in the future based on it's technology might. Currently the military has a large aversion lethal autonomous systems, so I don't think it's going to happen.

For single files or monitoring other pipe based operations (like network transfers) pv [1] is also a useful tool.

Game_Ender··on Code & Conquer: A War Game for Coders
There is a good discussion of this on progit [1]. The general consensus was there have/are lots of coding games, so this is not revolutionary, and the product is currently vaporware for a startup contest.

Game_Ender··on Go After 2 Years in Production
Google has said they don't use 'go get' internally to manage dependencies, so they appear to agree with you.
Game_Ender··on Giant Robotic Mining Trucks in the Australian Desert
You are incorrect. It's quite possible to achieve sub 10 cm level accuracy with an RTK based GPS system [1]. The problem is that you have to install base stations to gather the corrections and then have the radio towers to distribute them. Since mining sites are fixed locations, it's pretty straight forward to setup up the needed infrastructure for an RTK system.

So it looks like Rio Tinto is using Komatsu's system and BHP Billiton is using Caterpillar's. To my knowledge NREC only works on Caterpillar's system, it's just a coincidence the systems have the same name.
Game_Ender··on Giant Robotic Mining Trucks in the Australian Desert
One of the advantages of an academic institution like CMU (which NREC is part of) is that they actually have a good deal of commercial work which doesn't require US citizenship. For example the robotic mining project is shown here is not export controlled, and neither are the agricultural projects [1].

Game_Ender··on Giant Robotic Mining Trucks in the Australian Desert
Both the autonomous mining trucks [1] and the automated military convoy run on software developed by NREC [2] (a part of the Robotics Institute at CMU), and I have worked on both. It's a very cool place to work and we are hiring. If you have any questions about what it's like to work on these kind of systems ask away.

Game_Ender··on Groundwater Contamination May End the Gas-Fracking Boom
You would guess? You have to make decision based on more than guesses, at minimum you should analyze the physics behind the exact process going on.

Game_Ender··on A much-maligned engine of innovation
It doesn't look like most of HN is in the R&D field, but from the inside it's obvious why we need government funded blue sky research. Once you get into the research and science field you realize how many old ideas you are using, ideas which were just developed because of scientists were advancing the state of the art their chosen fields.

The fact is, it takes decades to realize the implications of fundamental breakthroughs in math, physics and chemistry. The long time horizon and inability to judge the worth of these endeavors at the time means a patronage model is basically the best bet. It's kind of sucks but we just have to pour money into research hoping for a better future.

Game_Ender··on Drone Blimps Hovering Over D.C. to Stop Cruise Missiles
It depends on what you call a cruise missile. We are at the point where anyone can take off the shelf parts and software and make a "drone" [1]. It's a pretty simple matter to modify the software to order the drone to crash into a building, motorcade, or outdoor event. Making an effective payload that can be carried by your small aircraft is another matter.

Game_Ender··on Navy Drone Successfully Lands on Aircraft Carrier
The reason you don't use tail sitters is because they have much less payload capacity. In that configuration the engine has to be able to output thrust greater than the entire weight of the aircraft. Something like the 737 has a thrust to weight ratio of only 0.25 (you need greater than 1 to take off vertically).

A more direct comparison: A fully loaded standard F-35 has a thrust to weight ratio of 0.87 (that is with the afterburners on). In comparison the short take of and landing version of the F-35 loses 43% payload of its and 25% of it's fuel capacity (and thus range) [1].

Game_Ender··on SpaceX's Grasshopper Successfully Flew 325 Metres
It's elegant because you "just" have to strap landing gear and some parachutes to your existing rockets and you can reuse them. You lose some payload capacity, but you get to use your rocket again (which is the expensive part).

We have tried engineering more complex re-usable lifting body type designs, only the shuttle ended up flying, and it wasn't cost effective.

Game_Ender··on Salt: Like Puppet, Except It Doesn’t Suck
You are wrong on all counts here. Salt supports Jinja2 template engine, so you can template your states [1]. You define custom states in python [2]. In the root configuration file (top.sls) you target configuration based on host name, grains (machine specific information) [3].

Game_Ender··on Watchman: Faster builds with large source trees
Not directly applicable but if you are using Salt to manage your servers you set it up to restart a service when certain files change with the watch requisite [1].

Game_Ender··on Rundown of the newest features in C++11 [pdf]
I have read quite a few overviews, and I really like the direct C++03 vs C++11 code comparisons in this one. It's get right to the point of showing the things that C++11 is trying to fix.
