The underlying technology for the Makani kites and a standard turbine are the same. In the Makani case you have one kite with eight turbines, and like a standard wind turbine, all turbines need to be serviced. If you have to service 1 turbine, the other 7 stop operating. Hence, on a per turbine basis, I believe availability won't be around the 98-99% level (the industry standard), but lower.

Additionally you have the tether, a new variable, which is another moving piece, and will also need to be serviced.

I've done some back of the envelope numbers, and without assuming a higher capex (which I'm fairly certain it is), on an recurrent basis, an increase in production doesn't really lead to cheaper $/MWh on an O&M basis.

Standard Turbine	Makani
Capacity (MW)	1.5	0.6
Load factor	23%	60%
Production (MWh)	3,022	3,154
Availability	98%	95%[1]
Net Production	2,962	2,996
O&M $/turbine/yr	20,000	20,000[2]
$/MWh/year	$6.75	$6.68

[1] I think I'm being generous at a 95% availability, but I haven't got enough data to make another assumption.

[2] O&M can be contracted on a turbine or MW basis. Still, given the "complexity" of Makani, the price of this could be higher than the standard cost.

This is a new technology, and not much info is available e.g. how big can these get, what's the investment cost per MW, what are the potential maintenance issues, how does availability look like, etc. My above argument is an educated guess, but I'd really like to know more about it. I really like the idea and I would like the economics to work out.
I feel that way too. The distinction between codepoint, glyph, grapheme, character, (...) is not an easy one, and that's what he seems to be stumbling over. Unicode worries itself about only some of these issues, many of the other issues are about rendering (the job of the font) or input.
I use VIM + Tmux for the most part. That being said, editors like Sublime, WebStorm, Atom etc are great and are a part of my tools collections.

The article was posted a week ago, but there are no updates about iOS 8.2 as of today and since it shouldn't be too long to just upgrade iOS and see if after 10 attempts the device gets wiped I'm guessing that the fix for CVE-2014-4451 actually patched this but the news wasn't as interesting as it would've been "iOS 8.2 vulnerable too" to update the post with

I found a big improvement to my model just after the contest was over, so I made a proposal to develop the improved model and do some more in-depth analysis. I'm currently waiting for their reply!

If they accept I'll have an opportunity to look deeper -- it's one thing to develop an efficient model, but fully exploiting it in order to gain a better understanding of the data takes some work. A limitation of these contests is that you're rewarded for producing a very efficient model, but there is very little emphasis on analysis of your model once you built it. I think it's a shame, because the person who built the model is often in the best position to have a good intuition of both the dataset and why the model had to be built that way.

I've been considering opening a blog, but I haven't found time to do so yet.

Briefly, the purpose of the contest wasn't to understand the effect of breastfeeding, but to understand how important normal child growth is to mental development. They included several scenarios: with all data available, with demographic data removed, and with demographic data and growth curves removed. Unfortunately, IQ is so overwhemingly affected by demographic that the scenarios without demographic data devolved into a game of extracting all the demographic data that was leaked by non-demographic variables. And when demographic data is available, more than 90% of the variance extracted by the model comes from demographic data rather than biological measurements!

It's really disheartening to think that depending on the social setting you come from, you start with an IQ of 85 or 115 -- at age 7...
The problem is that 'not a technical person' is a dying breed.

Take a long-term view of things - anyone born after 1985 will be the dominant demographic in 20 years. These people are more technically literate than the current dominant demo.

So yeah. My mom doesn't know IE from Chrome, but my 12 year old nephew does, as do all his friends. In 20 years, my mom will be 85, my nephew and his generation will be the dominant demo
It's all part of the image. Buffett gets a lot of miles out of the (authentic or not) aww-shucks folksy homespun image. He can do questionable deals and still not have his integrity questioned, and it's disarming in negotiations, in which, Buffett is as tough as they come.

What are you proposing? Because if it involves preventing him posting to mailing lists or restricting his contributions to kernel development I'm against, and on pretty fundamental ethical principles: you appear to think there's a deontological injunction against permitting someone to do harm by disrespecting others, whereas I think that harm should be weighed against the benefits that would be lost thereby.

I also think that your opinion on why Linus behaves as he does is wishful thinking, sorry. There's a decent chance he'd take his ball and go home if the above were done. That would be bad.

It's hard to compete with RStudio for best IDE for R. I stick with vim-R-plugin for most stuff but RStudio is so helpful for making presentations. But competition is good.

Excel add-on, on the other hand, seems very interesting. I lost lots of time in Excel before I decided to get rid of it instead in favour of R+SQLite. I wonder if it would be possible to make the add-on work under wine though.

Edit: just tried to get FasteR add-on under wine. Unfortunately, it requires .NET 4.5 with which I didn't have much success previously...
> Those who would give up essential dynamic range, to purchase a little temporary loudness, deserve neither dynamic range nor loudness

I love this adaptation.
Although the tracks have been normalised to have the same average loudness, the more aggressively compressed tracks that have less dynamic range will still sound louder at this lower level. I don't see how what YouTube is doing is going to help.

The examples you've cited look to be mastered (or at least sourced) differently. True loudness normalization should not affect the short term dynamic range of the material. It simply looks at the average level and lowers or raises it to some preset point. YT could be doing inter-song normalization, i.e. adjusting parts within the song to the same overall level - but this is not a good thing as it would affect properly mastered tracks too.

Your example seems to show a completely clipped sample (in the CD) and a more reasonably mastered copy (in the YT clip) with greater dynamic range. Once the dynamic range has been destroyed through compression (not digital compression, I'm speaking of gain compression http://en.wikipedia.org/wiki/Gain_compression) it would difficult or nearly impossible to restore without affecting the quality.

My guess - in this instance, I think the CD and YT clips come from different masters.

Thanks Martin, unfortunately it's past the point where I can edit my original comment or I'd go back and fix it. As I recall you said it off-mike in Bill Venners' talk, otherwise I would have fact-checked it!

Anyway, details aside I thought it was a great illustration of the impact on compiler performance that code complexity can have.
Wow, this is really HN at its best. Downvoting the doer for incorporating constructive feedback. sigh
Applying Replaygain or EBU R128 loudness equalization will not change the perception of dynamic range and, all other things being equal will actually slightly decrease the DR rating. And TFA is not talking about Replaygain-like algorithms from the description.
RPython is definitely a Python-first thing. PyPy is the only VM written in it that's actually production-ready at the moment. I'm guessing that has more to do with effort invested than any real limitations on RPython's part though. I'll definitely read up more on Truffle. :)
This discussion about HN link quality is old and comes up frequently. I'm mostly a lurker. Thing is, I haven't read a complaint about the "low quality on HN" in quite a while.

About a year ago or two, these objections would be posted multiple times every day.

Maybe HN declined from 5 years ago, but I think it improved over the last year or so, because a lot of marketing BS isn't here anymore.
News has been able to sell itself with the dictum that you "have to know what's happening!"

In reality, you really don't need to know what's happening around the world. Seriously. 95% of the news you read does not impact you in any meaningful way. Most of it is negative (which is the very nature of news) and too little of it concerns you in your immediate surroundings.

So yeah. You don't need to news. At least not 90% of what passes for news these days.

Poor people stay poor because there are so many systems in place that squeeze them, from usurious payday/title loan shops to rent-to-own places;

There are also utility deposits, auto insurance, etc. But, there are a tremendous amount of free resources available to poor people, from food stamps and food kitchens to clothing. It could be easier for someone with nothing to scrape together a few thousand bucks than someone in the middle class. If your food is subsidized, your income tax rate is low, and your lifestyle costs are low, e.g. not having to insure a home or expensive car, then you should be able to save quickly.

So, I'd assert that: Impulsive people, those severely uneducated in their economic alternatives, or those with little marketable skills stay poor because they continue to make bad decisions.
Sure, that's an option. A vegan should probably seek out another vegan to marry, rather than telling a meat-eater that she's wrong and has been conned by the system and that she's forcing you to buy some bullshit foodstuff that compromises your principles.

> Yet Mr Buffett’s 50th letter to shareholders is an exception, serving to muddy rather than clarify, for two reasons. First, because it does not tackle the questions that hang over Berkshire’s conglomerate model and its durability. Second, because of the uncharacteristic coyness with which Mr Buffett and his partner Charlie Munger —respectively aged 84 and 91—discuss how or when they will give up their jobs.

Did this guy not read the letter? Because Buffet spends a lot of time discussing why he thinks his version of the conglomerate model works and will continue to work. You can disagree with his reasoning, but he certainly discusses it at length.

Second, there have been rumors that Buffet is planning to give up control soon, perhaps at this shareholder meeting. Even if he doesn't, it's not clear that it matters. The final word on asset allocation may come from him, but he is surrounded by people essentially making those decisions for him (as he basically implies in the letter).

Nowhere in this do I get the impression this guy actually read the FULL letter, beyond the first part (meaning beyond page 21).

The developers' claim is that more than half of all security bugs are bugs due to memory safety issues and that Rust will solve these. More than halving the number of bugs doesn't sound marginal to me.

Lack of types.

I don't want to start a discussion here on typed vs untyped so please consider everything I say to be qualified "It is only my personal opinion and experience".

I'm writing Haskell in my day job, Clojure for fun side project, OCaml because it's a nice language that's a bit underused and C++ because it's useful to know and not so evil as most people say (and it's progressing fast!). I should throw Rust into the mix because it might have a bright future.

WARNING: personal opinions and anecdotal evidence ahead!

Maybe there's a level of lisp enlightenment that I haven't reached yet but I can't just get by with writing lisp without writing tests. On the other hand I can get by with writing Haskell and OCaml without writing tests.

This is particularly true when I'm coming back to a project that I haven't touched for a few weeks. I change something and something breaks. In Haskell and OCaml I change something and compiler complains.

Maybe we'll see HaLispML one day.

> This hyperbole serves no one. Modern limiters are tremendously transparent, and only people who are listening for it will notice the increase in compression.

Agree. Though, I'd add a qualifier - "...are tremendously transparent when used correctly..."

The one thing even audiophiles with the best speakers on the planet need to realize is that no speakers can approach the dynamic range of what modern digital audio have to offer us. Therefore, some tasteful compression (or limiting) will be needed, or the signal will launch the speaker cones out of their baskets.
Because you read the study ? there isn't even a link to the study in the article. The article is garbage.
As I understand it, tracks with more dynamic range will have louder loud's and quieter quiet's, while those with low dynamic range will have less of either.
Intellij all the way :O)
Doesn't the process of compression (to make it seem louder) destroy some of the information? I always assumed this was a irreversible process?

I haven't used Webstorm, and one of my colleagues uses SublimeText. I use NetBeans IDE because it integrates well with Git, and even without Git it keeps a history of your changes so you can diff against previous versions. Also has intelligent code completion, multiple views of the same file in a split screen. And the inbuilt FTP makes it easy to code directly on a remote server. It's really convenient for me because of these and so I haven't felt the need to use the others.
Both sound good, maybe you could highlight these on your landing page? The picker for RColorBrewer palettes looks particularly handy!
In lisp you have the power to easily invent abstractions. Strip things down to a bare minimum and you can see that your code is good. And write some tests just in case.

OTOH in strongly typed languages with rich type systems the actual code might be uglier and more complicated because you're constructing a proof of something. The property might be week (tests needed!) or strong (tests? what tests). Depends how far the rabbit hole you want to go.

At least that's my view on this.
Is this to do with multi channel audio?
On a another note, I wonder what all these intermediate helper devices will do to peoples driving abilities. We're already getting to a point where more and more people cannot drive a car with a manual transmission. How long before most people cannot park a car or safely change lanes on their own?
If the lower dynamic range tracks sound louder even after normalization then the normalization algorithm is flawed. ReplayGain weights the energy by frequency to better match perceived loudness, and it does a reasonably good job. Other algorithms might do an even better job at matching human perception.
