Previous discussion of a similar project, by [evidently] the same person: http://hforsten.com/6-ghz-frequency-modulated-radar.html

As before, this is totally awesome---until the FCC (or other national spectrum regulator) shows up at your door...

Here is an assortment of things that the author might be interfering with in the neighborhood of his 5.5 GHz carrier frequency: https://wirednot.wordpress.com/2014/01/07/what-else-is-in-th...

Some of this is the sort of stuff you really don't want to interfere with--both for safety reasons, and because of the likelihood of enforcement.

Next time I suggest that the author look into whether his jurisdiction will grant him an experimental license so he can do this legally. In many jurisdictions that is cheap and easy (unless, of course, you want to operate in a band where the interference risk is just too high).

Edit: I see the author is in Finland. Unfortunately for the author, I'm guessing this changes nothing since these frequencies are regulated both nationally and internationally. But it does mean that there is probably some local variation in the exact services that might be subject to interference. And who knows: maybe in Finland the 5.5 GHz band is a "do whatever you want at any power level you want" band. But I doubt it...

Is IRC supposed to be the car or horse in this analogy? I'm convinced of the former.
The reason I like R - it just makes data exploration and analysis too damn easy.

You've got R Studio, which is one of the best environments ever for exploring data, visualisation, and it manages all your R packages, projects, and version control effortlessly.

Then you've got the plethora of packages - if you're any of the following fields: statistics, finance, economics, bioinformatics, and probably a few others, there's packages that instantly make your life easier.

The environment is perfect for data exploration - it saves all the data in your 'environment', allows you to define multiple environments, and your project can be saved at any point, with all the global data intact.

If I want some extra speed, I can create C++ modules from within R Studio, compile and link them, as easily as simply creating a new R script. Fortran is a tiny bit more work, still easy enough however.

Want multicore or to spread tasks over a cluster? R has built in functions that do that for you. As easy as calling mcapply, parApply, or clusterApply. Heck, you can even write your function in another language, then R handles applying that over however many cores you want.

Want to install and manage packages, update them, create them, etc...? All can be done from R Studio's interface.

Knitr can create markdown/HTML/pdf/MS Word files from R markdown, or you can simply compile everything to a 'notebook' style HTML page.

And all this is done incredibly easily, all from a single package (R Studio) which itself is easy to get and install.

Oh yeah, visualisation, nothing really beats R.

And while there are quirks to the language, for non-programmers this isn't really an obstacle, since they aren't already used to any particular paradigm.

As for Python, I'm sure it's great (I've used it a little), but I really don't see how it can compare. R's entire environment is geared towards data analysis and exploration, towards interfacing with the compiled languages most used for HPC, and running tasks over the hardware you will most likely be using.

Making unfairness in new places isn't decreasing the amount of unfairness in the world, it's increasing it.
Let's look at the worst possible case for molten salt reactors and imagine that somehow the reactor gets cracked wide open.

With a solid-fueled reactor, you need enough fuel for 18 months (the normal refueling cycle). With liquid fuel you can add a little bit of fissionable material as often as you want, so your fuel has barely enough reactivity to keep your plant operating.

With solid fuel, the fission products build up over that 18 months. With liquid fuel, three things happen:

- Noble gases bubble right out of the fuel to an outgas system. You get a tank of xenon and krypton. You can take that away to secure storage as often as you like.

- Some metallic fission products plate onto collectors.

- The major fission products we worry about are cesium, strontium, and iodine. In conventional reactors they're gases, but in MSRs they bond very strongly into fluoride salts. Optionally we can remove them as we go.

So in our imaginary catastrophe there's not enough reactivity for a big excursion, there's less decay heat than in a conventional reactor, and most of the radioactive stuff is liquid that quickly cools to solid rock. There's nothing to drive any kind of explosion, since it's all chemically stable and at atmospheric pressure.

It's worth noting that Fukushima's reactor survived a 9.0 earthquake without significant physical damage. It was the loss of electric power that took it out, and that's a problem molten salt reactors don't have at all.
I should add - BIM automation is HUGE market opportunity right now.

For example, if the architect can design the building, then the engineering optimization is automated (plumbing is well-understood...), and the accounting, BOMs, and fabrication documentation are all automated. This idea removes the time-consuming and pointless conversations between architects, engineers, and the construction team.

This is the potential of BIM that I see.

Actually, the SDK is pretty easy to use. I wanted to directly fetch the streams of a major movie site and without visiting their site at all. Implementing a session rejoin when the casted device switched (E.g. android, windows or linux) was done in about 5 Minutes, in overall it just took about 1 hour to completely write a webapp from scratch for a video site who's user experience otherwise would not allow me to endure searching for videos and requiring to jump through a bunch of hoops to cast an HR movie directly.

An experienced programmer should be able to do this even faster, since I am a sales guy. Don't let the bunch of documentation overflow you, most of it is trivia.

There's a big dichotomy between the developers working for tech companies and the developers working everywhere else. Most tech companies do a decent job of taking care of people, but those 80-100k salaries are very common in the non-tech industries (who also employ thousands and thousands of technical staff).
GC Disabled, Memory required to process 10,000 jobs reduced from 1257 MB to 151 MB . So it may mean (unless there's a general overhead) that, 15KB of memory is used vs. 125.7KB previously. assuming the job still itself leaks the same memory it means sidekiq itself was leaking 125.7KB per job previously, am I right?

The main issue with IRC is that you have to stay connected all the time to recieve messages, and you have to leave your IRC client to see and search the logs (unless you have some intermediate IRC client server that runs all the time). It's just not as nice.
It's a network-attached browser engine on a TV. You can stream video, sure, but you can also load up an arbitrary webpage and render to the TV using standard web technologies. People have built multiplayer games played with multiple people's phones with the Chromecast as a shared area, such as card games. You could trivially show a persistent status page. Almost anything you can do with web technologies you can do on a Chromecast. (Notable exceptions: WebGL, and applying arbitrary transforms to live video.)

And in addition to client/server communication, you can easily send and receive messages between the page running on the Chromecast and the app or page that initiated that cast.
TBH, I still haven't had great luck with their pants. They just don't fit well, even trying several different configuration options.

On the other hand, their dress shirts are very high quality and fit (me) extremely well. They get me every time there is a sale on their dress shirts (like today).

I think the real difficulty with these business models is that the sizing numbers vary WILDLY across retailers, so there's a lack of consumer confidence when shopping - even with free shipping and returns. A 34x34 pant is not the same at J Crew, Banana or Bonobos. There are several other measures that impact the fit dramatically, of which the average consumer is not aware.

Show HN: MapMe.io, AR platform for IoT, primarily for transportation awareness
http://MapMe.io, a AR platform for the IoT, primarily for transportation awareness. Original motivation was to create an all-software solution for the bicyclist to be more aware of something coming up from behind - as I am mostly deaf. After a few startup weekends and intel edison incubators, I'm getting close to testing with small group of alpha users in a larger city like SF (where real-time data is available for public buses). The idea for the MapMe.io is to be the software platform where real-time notifications enhance transportation safety overall. Spotter view/tab will access the phone camera for "background" of app/"foreground" for user and the alerts will give relevant alerts based on user location.

had worried me a couple of years ago. JMW shows that vectorized was much slower also in Julia (though still both faster than R - but that's not difficult).

Glad to see Julia is very fast in both cases, though it's still somewhat perplexing the extent to which vectorized code is necessarily slower. I'm thinking that the future of GPU enabled languages will mean vectorized code will be faster, so I prefer languages with a bias towards vectorisation.

Let's talk!
Their menswear collection looks to be trying to compete with Banana Republic and JCrew, at least price wise. I took a look at their "experimental" women's line, AYR, and it's just... I mean maybe I'm not their target demographic but for $125 I can purchase some incredible pants at Nordstrom and actually try them on in the store, not to mention have a great customer service experience and get them tailored in-house. Their women's line suffers from overly high prices for what the pieces are (simple stuff that I can buy at Ann Taylor or Loft or Nordstrom or JCrew or Banana Republic depending on my mood and what color I want it in), and the extremely narrow offering of sizes is straight up ridiculous at this point.

I'm not going to drop $150 on any clothing I buy online sight-unseen unless it's a brand I already know and trust. And yes, I can return it if I don't like it or if it doesn't fit but if I'm spending $500-1000 on clothes at a time (and at Bonobos that's two pants and two shirts plus a blazer) I don't want to go through that hassle, I want everything to be perfect the first time. I imagine that for most men their desired shopping experience is even more geared towards "I want to purchase the most adequate pair of pants the very first time and minimize the time I need to spend shopping."

I do have a few friends who live to shop but the vast majority of my friends, male and female alike, just want to buy things they like and have them work the first time around with a minimum of fuss.

Plus, if I'm going to spend that much money on clothes that I have never purchased before (and I consider $200-400 per outfit to be a significant outlay of money for clothes, which perhaps makes me an outlier) I want an experience to go with it. I want to see what I'm getting before I pay for it, and I would like the option to consult with a salesperson about the clothing. Their men's Americano and French Cuff dress shirts are in the same price range as the least expensive shirts from an awesome independent men's store close to my house (in the DC suburbs) and every time I've been in there to shop with my husband he's treated like a king by the staff, as is every other customer that comes through there regardless of how much they spend. Again, when I shop there I know damn well that whatever I buy is going to be the absolute top quality that it can be because the owner cares about his customers and doesn't sell anything he wouldn't buy or wear himself.

Corporate Personhood is an intentional design goal of US law.

The earliest case I'm aware of dealing with "corporate personhood" is The Rev John Bracken v. The Visitors of Wm & Mary College, from 1790, which is discussed in the linked article [0] (page 434 discusses the founder's wishes, treating the corporation as an extension of the will of its founder, through its charter.) The rest of US case law, long before Citizens United, follows this same pattern -- corporations, being "merely associations of individuals united for a special purpose" [1], function legally as individuals in many ways, with the right to speak and own property and other such things that fit with the purpose for which they are founded.

A relevant quote from US case law: "The principle at stake is not peculiar to unions. It is applicable as well to associations of manufacturers, retail and wholesale trade groups, consumers' leagues, farmers' unions, religious groups, and every other association representing a segment of American life and taking an active part in our political campaigns and discussions .... It is therefore important -- vitally important -- that all channels of communication be open to [all of the above types of associations] during every election, that no point of view be restrained or barred, and that the people have access to the views of every group in the community."

How fast do these go compared to a bicycle? I saw a few of them on the street and they didn't seem to be moving faster than a brisk walker.

My impression was that bikes are generally banned because they move fast enough to cause serious injury yet are silent enough that pedestrians don't hear them coming.
> No problem with people saying "it's useless" as long as they make their point with some arguments

My opinion differs:

1) IME, comments which begin with hyperbole such as "it's useless" rarely improve beyond that. I generally stop reading there (I don't have time to read everything). My theory, anecodotally confirmed, is that if they are careless with their language (i.e., the lazy use of hyperbole), probably they will be careless with their content.

2) It's rude to whomever wrote the article, and it also creates that environment for interactions between commenters.

3) That kind of rant is like a virus; it spreads through discussions and through the community. I believe this concept is well-established among veteran forum maintainers. From Paul Graham, talking about what he learned from running HN: [1]

It's pretty clear now that the broken windows theory applies to community sites as well. The theory is that minor forms of bad behavior encourage worse ones … I was living in New York when Giuliani introduced the reforms that made the broken windows theory famous, and the transformation was miraculous. And I was a Reddit user when the opposite happened there, and the transformation was equally dramatic.

...

Bad comments are like kudzu: they take over rapidly. … If someone submits a lame article, the other submissions don't all become lame. But if someone posts a stupid comment on a thread, that sets the tone for the region around it.

Hmm I am curious, how would you do data cleaning without doing data exploration first -- and in what way do you find Python superior to R for that purpose?

Also I assume that by "something non-standard" you mean something other than a way to analyze it? Because there is really no comparison wrt available analysis packages between the two...

Not trying to say that R is perfect and great for everything, definitely not, I just have a hard time imagining a data-processing task for which I would choose Python over R (I might pick SAS over either one of them though...)

I'm a cyclist and I love the idea of making cities more bike friendly, but this group of designers has missed a major point. Cities are for PEOPLE. Not for cars, not for bikes, but for humans. Space for people to live and exist in should be the highest priority, and anytime you start cutting into living space to make more room for vehicles, you're making the city less human friendly. That's what these guys seem to be doing. They're saying, "cars aren't important, bikes are!" But neither bikes nor cars are important. People are.

I'd even suggest that a major reason why cars have supremacy at the moment is that they are more inclusive of people than bikes are. I prefer using my bike any time I possibly can, but I am young, fit, childless and live within 2 minutes of my job. Cars are inclusive of people who have more than one kid, live across an interstate from their job, and may have mobility issues - and bikes are not. This redesigned city needs to make room for people who aren't 25 years old and single.

I was working on iBot cost reduction stuff back in 1999 when that patent was filed. I was under the impression the company (our customer) had a lot of balancing machines running around at the time and figured the patent must have been a few years old at that point. Guess not.
I mostly agree. I do sometimes find valuable counterpoint in the HN comments, but most often that's on topics where the community here has actual expertise (mostly programming) and the counterpoint is pretty specific.
