Some cool stuff here. We've been shooting with RED Epic for a while now, and the extended dynamic range of the HDR-X mode is really nice. It's about 18 stops of dynamic range. I can pull almost anything out of high contrast scenes in post-production - we don't have to wait for the magic hour anymore and can generally wave goodbye to blown out skies. Check out londonhelicam.co.uk - there are a couple of HDR video examples in the reel.

I wonder if this Tegra 4 chip will have enough horsepower encode the extended dynamic range of the HDR video into a usable 16bit/32bit video format, at good quality bitrates. What codec would it use? h.265?

Sony has the best dynamic range in consumer sensors, hope there will be some products combining this into a truly usable and user configurable product - either in a phone or a consumer camera.
When was the last time you had to wait in one crowded room for 3 hours without being allowed to use your phone, and without a seat?

The last time I was in a situation anywhere close to this was when I accompanied my girlfriend to get her visa renewed in London. We had to wait for about 5 hours in a fairly crowded hot room with pretty uncomfortable seats. But we had each other's company and while there was a sign saying we weren't allowed to use electronic devices, most people seemed to be ignoring it, so it wasn't so bad.

But still worse than anything I ever have to experience in my normal travel as a white British man.

Every few years, there are fashions in our industry that feel like moral virtues to follow; structured programming, object orientation, patterns, functional, TDD, IoC. They warm the cockles of your heart, make you feel good about yourself.

But I am suspicious of this feeling, because it is an emotional in-group attachment, a bit like a religion. All religions have costs to following them, so that disbelievers may be easily recognized and (to a greater or lesser degree) demonized. But the world isn't and shouldn't be so black and white. Actions should be analyzed more carefully, and above all, rationally.

Code structured in a fashionably virtuous way makes me suspicious that the situation may not have been analyzed dispassionately. The style may be an end in itself.

I'm especially on guard because I used to be an acolyte of the OO religion.

I just gave you a few reasons why "if the program works on one distribution of Linux, it tends to work on the next" is not true. The C++ ABI keeps changing, even between releases of the same distro. They don't provide backward compatibility, it just stops working.

Americans, to an absurd degree, are rabidly ethnocentric. I'm not sure why this is; I think it has to do with being the major superpower during the global information explosion era.

I'm speaking as an American myself: I have a very hard time, despite being conscious of it, not thinking of all things American as a baseline for normalcy. I know, intellectually, that American dialects stagnated for centuries after being imported from Britain and eviscerated by Webster, but I still think of "colour" as a foreign and exotic spelling.
I think that their fundamental characteristic might be reduced to a very low emotional response. This explains their lack of empathy and lack of fear. The ruthlessness, charm and cold manipulator behavior are just by product resulting by the need and desire to reach their goal as any normal person have. The lack of empathy, fear and apparent consciousness make them more efficient but also less socially fit because they are deaf to other people's pain.
There is actually an arduino shield that let you integrate arduino with the Lego microcontroller, so you can expand the number of inputs and outputs, though this is mostly a transition from lego to arduino, because at that point, you better off doing everything through an arduino (except that you get to use your lego motors and sensors with it this way). Here is a book that teaches about how to do it and talks more about the arduino shield:

I've had a fair few experiences with various companies where normal channels fail and the only way to get prompt action is to use twitter, or a similar public channel.

It's a pretty sorry state where the only way to be taken seriously is to make a public fuss rather than just having a quiet chat like two grown up human beings. Every time I'm forced to do it I feel like the kid throwing a tantrum in the snack aisle.

Hell, it gets results, but it degrades all involved.
NQC was my first real world experiences with coding. I remember making a printer with one of the original RCX. It consisted of three motors, two rotation sensors, a pen, and a computer-side script to turn images into black and white "halftone".

The output was predictably bad, but I had a lot of fun making it.
What a great way of putting it, the tree rings idea. Will look into Derrick Jensen. Thanks for sharing.

Crowd sourced sports broadcasting - could this be done?
Yes, you pass in Random, and file streams.

If you need to pass the same set of multiple things to multiple functions, you declare a type that represents all these arguments. At least this is the approach used in Haskell, with semi-explicit (explicit in type, implicit in the value) passing of parameters.

If you take a time argument, you have to declare an extra argument, not an extra variable, and in a powerful language, you can abstract its passing around.

If you move the method to a new location where its input is not available, you propagate up the input requirement in the form of argument passing, which conveys the new dependency up the call chain.
Regarding the 'publish!' method, the post linked to in DHH's example (http://weblog.therealadam.com/2013/01/03/design-for-test-vs-...) explains this as a 'trade off' - the summary of the other side being that if you don't pass 'time' to it you get a simper API.

This is somewhat more nuanced than your and DHH's conflicting opinions, and perhaps I show my inexperience (as primarily a ruby programmer), but this seems very sensible to me. It also reasonably describes why DHH's opinions may differ from others because of the focus of his work (in addition to the language used).
Higher student ratings, for example, actually negatively correlate with student learning:

Well... duh? Obviously students are going to give higher ratings to professors whose courses seem easier.
DI to swap out an implementation at runtime is an extreme edge case, though "runtime" may mean "the app can determine at startup which implementation makes sense". If you want to have a look at a nice usage of DI, peek into the source of Elasticsearch. You can swap out pretty much any relevant part of the implementation. You can for example change the HTTP acceptor to provide authentication [1] or add SSL [2] So there are cases where changing the implementation makes sense.

Why Hackers Are So Much Funnier Than You Are

I think it's many teenage boys fantasy to be a spy, or to run a spy ring. Many create their own secret societies, etc. Some get into computer security and hacking, and are part of real secret societies.

So you're super rich, seriously into security concepts, and bored. Probably you've met a lot of intelligence agents, and heads of intelligent agencies. Maybe you developed a bit of a fetish for spy-novels. Hell, what have you got to lose, let's set up a spy-ring! Just not in the USA... pick somewhere that's within private jet reach of the USA... Honduras, Belize, Guatemala... all interesting places!

Using a link wheels Since your Marketing Technique for High Website traffic
Marketing techniques have got evolved as opposition for website traffic improves. The reason being there are lots of webpages that are targeting the exact same market portion. Because of this , why one must think beyond the package and use any linkwheel as an easy way of making certain the actual webpage receives optimum online traffic going for the web page. Considering that the keyword usage and also Search engine optimization therapy has been utilized and also this unearths 1 page to unnecessary competitors
That's interesting if stereotypical ;)

That's only what it appears like on the end user's side. On the developer's side, it's much more messy. We're talking about binaries that stop working between two releases of the same distro even when the APIs don't change.

It's easy to dismiss this with saying "it's part of the deal" but if it takes too much effort for minimal gain it's not worth it. I'm fine with breaking changes if they improve things but there should be at least a compatibility later for some period of time.

Unfortunately, simply shipping different versions of a library is not enough to provide compatibility. There are two issues at work: 1) as mentioned before, platform ABI changes 2) ELF works with a big flat symbol table, so if you load library foo version 1, but a dependency loads library foo version 2, then things blow up.

You have to take a bit longer view.

Several generations ago it was normal that Europeans had a major war once a generation. Every village in Germany, France, Britain has a monument in it with long lists of names of men who died. Today we can all move freely, work together, share ideas, in many cases even share the same currency, etc. That sometimes causes friction, people like to complain, and newspapers run the occasional sensationalist headline to sell copies. The reality is literally millions of EU citizens now travel in, do business with, interact with, study in, and (in the case of EU elections) even vote in each other's countries. We've come a very, very long way. It has become so normal it almost isn't mentioned any more. Does that mean everything is perfect when different cultures meet? No, of course not. But at least we're not killing each other anymore.

I hope next year when we reach the 100th anniversary of WWI (the sheer scale of the carnage is difficult for us to even fathom today) more is made of how far we've come. And if you think that this progress was all inevitable, consider as a counter example that in our lifetimes there was still ethnic cleansing happening in Europe in Yugoslavia. Peace is hard work, we should all be very thankful.

I don't think it really bothers anyone here, so they haven't really tried to change it. We have a lot of live shows on all timeslots (morning, mid-day, afternoon, and night), so if each one overruns by a bit, another one must compensate. I think that might be (part of) the reason.
When I crossed over from Kazakhstan into China I got the most thorough luggage search I've ever had (never been to the US). Everything taken apart and went through; I was carrying the card game Citadels and had to struggle a little to explain what it was (my fault - I speak neither Kazakh or Russian nor Chinese, he spoke a little English). It was all very professional and courteous, and actually over quite quickly, but it was thorough, and having soldiers in uniform going through your stuff while you stand there in your pyjamas is always going to be a bit intimidating.
For which any simple configuration mechanism will do, and as long as you stick with coding to the interface, the problem is solved. So while technically this is called DI in Java, it's simply code taken as granted in many dynamic languages because of duck-typing. So yes, this is totally valid use case, but one with no need for a DI container in dynamic languages to solve.

Reflecting on this a bit more, the popular OS's that are not linux-based predate linux:

- Windows 8 (RT/Phone): NT kernel development started in 1989.

- BB OS 10: QNX 4.0 released in 1990.

- OS X 10.8 / iOS 6: NextStep first shipped in 1989.

What is strange to me is how little-used BSD is, given its more permissive license.

You're analogy may be a nice one, but I don't feel this detracts from the details of the piece. I am a professional developer and have a MSc in Mathematics yet the maths in this article is at the very upper reach of what I can understand. Terence Tao is, by most accounts, a brilliant mathematician, with both clarity of vision and nitty gritty technical excellence. Sometimes different disciplines talk of the same things in different languages, it's true, but to declare that the description in your discipline trumps that of another's before you understand both in detail is miss-guided.

It's not apparent to me what was used when calculating the frequency of bigrams, n-grams. Was this based on the overall dataset or the dictionary alone?

I believe it's beneficial to see a version that's based on the dictionary words alone as that would ensure no duplicate words exist to effect the n-grams, acting as a control group.

His formula doesn't make any sense. Health=micronutrients/kcal is a useless approximation. Implies that if you reduce kcal by switiching to more micronutrient dense foods, you'll always be healthier. Which is untrue (there are problems such as starvation, hypervitaminosis, drinking saltwater would be a great idea...) and highly depends on a plethora of other factors.

It's pseudoscience.

(And I say that as a future MD who also does science based sports/nutritional consulting, so be assured I know of the importance of diet and exercise in disease&health.)
There are far better sources out there.
I think "sighted" is preferable to "healthy". Just for future reference.
I was trying to find a succinct way to express that I had no disabilities rather than just that I can see. I'm aware my phrasing was awkward but hope people would realise there is no offence intended.
Super Smart Bike Sharing
I'm not sure I agree with this bit:

Meanwhile, the same kind of exertion (and political luck) in finance or software will have you able to retire: not in luxury, but at a middle-class standard of living that could be described as "making your own tenure". Also, you get to live where you want, instead of rolling the dice on where in the country you will end up living.

In this realm, I really don't think software, finance and academia are all that different. You go where the work is, and on average, the best you can do is to nicely secure a comfortable, upper-middle class position for yourself with plenty of job security.

You're right that being lucky enough to get a tenured position, but "applying that luck" to software or finance, can make you a millionaire. Problem is, that kind of luck is not a known probability on which we can set rational expectations. If I go work 80 hours/week at a software start-up, I can't expect even a 3% chance of becoming a millionaire. It's just not a random process with a set probability distribution. So you can't "apply your luck" to software instead of academia, because we're talking about two different kinds of luck.

Ask HN: help me get admitted into a great university
Hello, I am Ivo Georgiev, 17, from Bulgaria.
I assembled my first electronics project (music amp) at 7, wrote my first program at 10 all by myself.
Since then, I have built a game, helped start a quality Bulgarian media website, made couple of mobile apps, took some freelance projects and contributed to/built open-source software.
My dream has always been to start a software company. I have always had a concise idea of what this company should do. But it is only until 2012 that I started working seriously on that.
Anyway - to the point. I am one year away from finishing high school, and I honesty don't know where I see myself in one year.
I see that a lot of students on HN are considering directly starting a startup - but being in Bulgaria does not exactly help me.
I am sure about two things - I want to live in another country ( any place with a nurturing startup infrastructure ), and I want to go to a prestigious university (because I want to be surrounded by brilliant people) and study computer science.However, I have two problems - 1) my academic record - the only thing I have are my high school grades ( 6 - the Bulgarian equivalent of an A - in every subject except geography ).
In Bulgaria, we don't have accelerated programmes or any academic help for students like me. So my excellent high-school grades are all I have here.
I am taking SAT and CAE in a few months. I have a nice programmer portfolio, but I don't know how important is that.
And 2) - even if I do accepted into a prestigious university - my family (middle class in Bulgaria) cannot afford it. Of course, there are scholarships with which I can make it,
but that requires an even more outstanding academic record.My question is - if there are people reading this who, at some point, were facing a similar situation, please share your story.
Actually, any advice from anyone would help - which university should I choose, how can I get admitted, and how to support myself financially.
Thank you.
How to refurbish all transactions log reserve in SQL Server
I wonder if this is offset by industrial loads that are integrated into the network to drop their loads within milliseconds or short timeframes? Large server farms that do offline processing can instantly turn off large loads without problem e.g. Youtube background video processing.

India has perverse loads too: "Microtek, an Indian company that specializes in selling power backup inverters, claims to have 100 million satisfied customers.". I have read of the same thing happening on water networks, where individual households connect pumps to the the public water supply to suck water when pressure drops too low (supplier can then only restrict rate rather than control pressure, and customers at end of line go without!).

Many Inverter loads have a bigger problem in that they often only suck current at the peak and nadir of each voltage swing (Volts), leading to an ugly non-sinusoidal current waveform (Amps) with odd or even harmonics. Networks add large expensive HV equipment to reduce harmonics. Networks also charge large industrial users more if they have bad current waveforms (either harmonics, noise, or power factor).
One has to remember that our bodies' ability to cope with all sorts of diets and environmental factors was most probably a very beneficial thing for prehistoric man. For them it wasn't possible to just change their diet or lifestyle, if their tribe didn't catch game in some time, coping with less nutrient food was essential. And vice versa, when they got some meat, it was good that the body stored fat so they could survive until the next kill. For us, it could be nice if bad lifestyle choices manifested themselves faster in our condition, but that would have killed our ancestors.
