Nope, you're wrong. It's not really military. This particular project has been funded for many years by DHS.

It's based on radar tech that has been used in many past space-based contexts. For synthetic-aperture-radar-based mapping of Earth's topography from space (http://www2.jpl.nasa.gov/srtm/), for radar science (e.g., looking beneath the surface of Mercury using the 70-m Goldstone radar, http://www.nasa.gov/vision/universe/solarsystem/mercury-2007...), and for precisely retrieving the Doppler shift of receding spacecraft for science and communications. (Source: I know some of the JPL radar group.)

There is military-funded work that goes on at NASA, but this particular radar tech is not such an example.

Why should I use tmux over screen?

Why do I use screen over tmux?:

- its old. A stable version is on every distro. Trying to start a screen session is more likely to succeed on any given box than a tmux session. I see my friends wrestle with their tmux setup being more recent on one box than another and their nested sessions get screwed up. I never have any issue.

- I know it, and for my simple use it does everything perfectly. I can split panes, I can detach and come back, I can nest sessions.

- screen can attach to serial terminals.

What's the killer feature of tmux that I'm missing out on?
Sourceforge's downfall was not finding a better business model than advertising – which has devolved into the worst kind of spammy ads. GitHub, on the other hand, has a solid business model that doesn't involve advertising. In fact, putting ads on the site would be suicide.

Kubernetes uses Docker (or now rkt) to do the actual containing. The focus is on scheduling and managing lots of containers.

You may run O(10) containers on a single machine. When you run O(10k)+ containers in a cluster you need new tools to manage things.

If you feed one AI a tagged data set to train it, I think you would be able to easily hook it up to an untrained AI to train the second AI. As in, pass the first AI an un-tagged input, get it's result, and pass the second AI the same input tagged with the first AI's result. That would be essentially the same thing as a crow learning from watching another crow, aside from the fact that the crows are self-directed.

In a sense, nukes were more peaceful - the practical effect
was to replace large armies with nukes for cost reasons. Using nukes destroys them, so there's a disincentive to
actually use them. They're only any good if you don't use
them. That's some catch, that Catch-22.

> How do you feel about the phrase "MIDWIFE's are in demand"?

Well, for me, bad, but mostly for reasons unrelated to the main issue in the discussion -- because it uses an apostrophe improperly for "look out, here comes an 's'", and because the plural of "midwife" is "midwives". ("midwifes", without the gratuitous apostrophe, is a word, but its the third person present of the verb "midwife", not the plural of the noun "midwife".)

I understand your point. My pricing is entirely based of what I learned about the sphere in a hour that most of the cheap writers charge half a cent/cent per word, which would make around 5$ per such article and multiplied that by a big number/10x sounded good/.

I am curious though, what an article written using this outlined process will cost? How much would you charge about that? I am pretty sure that I won't be able to afford you though as anything above 100$ per article will put my startup back in red, which is a scary prospect for now.

Excellent overview. I'm sick to death of landing pages that are vague, hard to navigate, and leave you wondering what the project is all about; you avoided all of that. In particular, the "Decisions made for you" clearly answers many of the questions someone will have when they investigate a project like this. Kudos.
Does using tensors for storage yield some benefit over the 'panels' metaphor that Python Pandas affords? It seems like the real power of tensors is in the calculus that can be run over them, rather than just them by themselves.

If I want to store lists of numbers, arrays and (linked) lists are basically equivalent. It's when I want to calculate cross- and dot-products that vectors prove especially useful.

The discussions I've seen recently in data science about tensors seems to only be about the storage aspect. And, I suppose, if your libraries _don't_ provide such a storage mechanism, then yes, you'll benefit from adding that capability. But I keep waiting for more from the ML community about leveraging differential geometry full-on. I assume it's out there somewhere, in some shops, but I've not found a lot of discussion about it.

I don't think it is so simple.

In the past it was legal to produce and distribute it. Most people didn't care enough to stop it. In a relatively short time certain groups turned it from a 'meh, not my problem' to 'kill it with fire, nukes, lasers, and anything else we can throw at it'. They could potentially do the same to bitcoins. (You can even find there was a period where most all child abuse wasn't considered a problem, with one of the key cases of the era being a case where the lawyers for one abused child argued that the child should be legally considered an animal because at that time animals had greater protection). And the numbers of individuals into it are larger that most people realize (consider that 1 in 5 children are sexually abused by the time they reach 18 to know just how large the problem is).

Now, maybe certain factors like the potential demand growing for bitcoins would be enough to keep it from being banned. Also, even if you could get the public worked up about the topic, it is much harder to shock and awe them. What would a pro-ban advocacy group do, show numbers of wallets? And the ability for the government to scare people has taken a hit thanks to the backlash from the war on drugs.

How to Monetize an Open Source Project – Piwik
I've been doing a 4-day work week (working 80%) and it's great. If you're in a circumstance that allows you to do this (and I recognize that most people aren't), I strongly recommend it. It gives me much more time to spend with my family - I know it's a cliche, but kids will be gone before you know it so spend time with them while you can. The 4-day work week also gives me much more time (nonlinearly more) to spend on side projects.

A few disadvantages: First, I only get paid 80% as much. Second, it took a fair bit of effort at work to set this up; management was supportive, but they'd rather I worked 100% and it took multiple levels of approval. Third, this basically puts me off the career fast track. Fourth, from a social/cultural point of view, people don't really understand working 80% and I find it's better not telling people about it (thus the throwaway). Finally, I feel sort of a personal pressure to make the most of the extra day - I no longer have an excuse for not accomplishing more. E.g. why am I on HN when I could be writing a book :-)

Hey everyone, I'm in the main engineer on this project if anyone has questions.

Facebook has a large codebase, so naturally we have a lot of long filenames and paths. It's a pain to type these out by hand, so I'd see a lot of (new) engineers select the text with their mouse before pasting it into the command line.

This is pretty inefficient and I knew there had to be a better way, so a few of us started hacking on a set of python regexes and a curses UI. Before long we had a pretty simple / easy command line utility that sped up everyones' day.

After a while we realized this would probably be helpful to all, so we open sourced it today!

Unfortunately,

"the House Committee on Science, Space, and Technology approved a budget authorization for NASA that would see continued spending on Orion and the Space Launch System but slash the agency's budget for Earth sciences. This vote follows the committee's decision to cut the NSF's geoscience budget and comes after a prominent attack on NASA's Earth sciences work during a Senate hearing, all of which suggests a concerted campaign against the researchers who, among other things, are telling us that climate change is a reality."

If you're big into crowd-sourcing:

There are super-inexpensive RTL-SDR dongles[1] that can be used to track airplanes such as this.

I'm not a lawyer, but I've fooled around with these dongles and a few programs enough to discern that Gov't aircraft absolutely need to broadcast their info on the 1090MHz band.

It wouldn't be much of a stretch to have a few people pop these up and see if they could monitor the airplanes that are monitoring the city! :)

Just to expand a little bit:

You get an SDR, plug it in and use a program like `dump1090` or FlightAware. The repurposed TV Tuner will then listen to data on 1090MHz and decode airplane's Active Dependent Surveillance-Broadcast (ADS-B) messages.

The ADS-B messages typically contain flight callsign, location (lat,lon), altitude, heading, and a few other tidbits.

There's a really active community around things like this. [2]

First of, Thanks for this technology that helped save some of my countrymen. This goes to show that technology can indeed help in many avenues to save lives. I am originally from Nepal living in NYC, and looking for ideas that could create technology-aided sustainable development as a key to rebuilding. Ideas that come to me, which might have high $$ values for implementation are - 3D printed housing, Organic Farming for quick rehabilitation on these villages, Open-Source BTS for communications etc. As costs go lower, these affected areas might be the right place to implement these. As much as I am devastated by what is happening in Nepal right now with the death toll only rising, I would like to reach out to the technology community out here or anywhere to provide me with ideas into helping us rebuild. Most of the relief efforts are donation-based, however, for longer term - creating a sustainable economy in these low privileged areas with the help of emerging technologies is what I think is crucial for faster recovery.
All these development are really excellent.

The more people who are interested in solving these problems the better.

Neural Networks are awesome - but modern AI tells us that there are also various other techniques, The problem with Neural Networks is they are essentially a black box and many mathematicians and engineers are not happy working with black boxes.

I like the project. You integrated a lot of well known and standard packages that people writing Go-WebApps would want, and didn't make the project super heavyweight. Very useful and still very light. I will definitely be using it, since one of my biggest problems with getting new go machines set up is going out and finding all the packages I have used in the past.

iPhone 6 Case Converts Wi-Fi and Bluetooth RF Signals into Power
Hm, I think given your stance now I'm not sure whether I properly understood what you said elsewhere on this matter.

"Purity" is a tricky technical concept that can be defined, but rather than do so explicitly I'd rather note that it necessarily requires the asserter to take a stance on what "observable" means. Haskell is clearly impure in that its laziness is implemented using mutation "behind the scenes", but it is also taken to have an "observable" semantics where such mutation is invisible and IO is merely an interesting value. This gives it purity [0] according to that degree of observability.

I think I'm having difficulty parsing your interpretation of purity because you're moving smoothly between analytic and synthetic judgements of the notion. Agda, as an example, is a system which has a synthetic notion of purity as the "language" is thought to not contain terms which represent effects. Haskell plays a trick where it has, essentially, two sets of semantics. The first shares this property (modulo non-termination, see [0]) and is where most "programming" occurs---here we use monads as a system for constructing terms of the second semantics, IO. The second, IO, semantics are vastly impure.

To the degree that this trick is "purity in a language" then purity is becoming a very popular idea. Haskell uses its type system to provide synthetic distinction between the two choices of semantics, but if you use a language lacking that discipline then you can merely call this "isolation of side effecting code" and then nobody will disagree with you.

If you don't want to call this "purity", and maybe you don't, then I feel you're in the minority though you aren't without an island to stand on.

Frankly, both are sort of an overloading of the term, though.

[0] Actually, it gets a lot trickier. It's well known that non-termination is an effect and it's a little slippery to define Haskell's notion of "observability" so as to no longer observe non-termination. I mean "slippery" here to say that it takes some technical finesse and that it tends to go against people's intuition a bit more harshly than the rest.

I know that the amount of gun violence in the US is sometimes a shock to Europeans/foreigners in general, but I think a more pertinent question for most Americans is "Is the cost/benefit ratio worth it? Is this a proper allocation of public funds, or is it just another toy for local police departments to use?" My surprise in seeing that this is a sustainable business is this latter point: single-vendor sourced items and IDIQ contracts are a recipe for government spending disasters.

EDIT: My impression is that gun crime is heavily concentrated down to individual blocks or neighborhoods in urban areas. I don't like the idea of these devices in general, but I imagine that if they were deployed, they would be concentrated in so-called "high risk areas".

TL;DR They do triangulated time of flight for EM emissions from lightning strikes.
As far as I see it you waste money that could be better used in staffing police, implementing social programs etc - this thing is a solution to a very tiny problem: gunshots that are not reported via emergency calls. As far as I can see this does not help with robberies, burglaries, attacks with fists/knives/bats etc.

Even if its not a slippery slope - I'd imagine there are several better alternatives where you can spend the money.
