I would agree that it breathes life into a pretty neglected piece of equipment, but my concern would be that it isn't in any way entertaining, and the common element in the great innovations as of late have all catered to just that; keeping people entertained. Its defintely an exciting idea, but I just can't see anybody become truly taken with their thermostat.Perhaps its a jaded world view, but I feel that there is great demand for games and distractions, and not necessarily quality products or innovation. I can't help but consider that RIM is struggling for market share, and its largely been attributed to a lack of innovative games/apps.

I do agree that this product presents a greater benefit to the earth and humanity as a whole, but my concern is that the populous may not notice. Will enough people buy in to make this economically viable? I certainly hope so....

I've been to all of Australia's mainland capitals (sorry, Hobart). I've lived for long periods in Darwin, Sydney and Perth.

I prefer Melbourne to Sydney based on the time I've spent in each. Melbourne seemed a bit more cosmopolitan, the people a bit less artificial.

I'd rather live in Perth than either, but the startup scene here is quite anaemic. You can round up some geologists and raise tens of millions to do some mining exploration; but raising a few thousand for a startup is, from what I've heard, nigh on impossible.

I prefer Darwin most of all, but it's a government town and FIFO base. There's some IT service outfits but that's it.

Give me a tap that will expand that sweet spot between way too hot and way too cold.
nice thing, but instead of (re-)heating your home all the time "to the point", it makes much more sense to keep it at (almost) constant temperature by not letting the heat escape, which means good insulation.

From what I've understood, Randomo and Quorum's syntaxes share the same structure. Only keywords and operators changed. Therefore, Randomo has a much better structure than what we could expect from a truly randomly generated language.

So, while it still looks pretty bad for Perl, I'd say it's not that bad.
As long as 'comfort' includes monitoring humidity and adjusting temperature accordingly, I'm in. Did anyone notice if Nest does this?
Terrible audio, wish I could bear it though. Really wanted to listen.
I've made the numbers match (i.e., same cost for PV installation or using power from grid, assuming defensive increases in cost of electricity for the next 15 years - only going up as much as inflation) with a slightly higher subsidy (1000€ subsidy on an installation cost of a little under 12k€, which would only buy an installation that doesn't produce 100% of an average consumption).

But when the costs converge this closely then small assumptions can tip the scale one way or the other - one % extra opportunity cost, a converter that needs replacing 5 years earlier, 10% less sunshine in one of the earlier years of the installation's lifespan, ... That said though, when you extrapolate costs of grid electricity of the last 10 years, and base your energy price scenario on that (instead of keeping up with inflation like I did), PV comes out ahead even when taking worst-case scenarios of all other variables.

Many people argue that because prices are falling so fast, it doesn't make sense to buy now. But IMO it's much more nuanced than that:

- As prices fall, so will subsidies. Already most subsidies are being phased out or decreased.

- There is a floor on the prices - in the short term that floor is just below grid parity, in the medium and longer term it will be production limits. I don't think it's rational to assume that prices will keep falling so fast.

Many words have been shed on this - I guess only time will tell. That said, like I posted elsewhere here, my parents are getting an ROI of 11% on their panels. That's mighty good for money that can be borrowed under mortgage, and 'green' == cheap mortgages for that matter. (that yield is only because of subsidies though, so it's not really a fair general case comparison).

My Favorite Test Question of All Time
A mechanical thermostat (like the round ones) is just a switch i.e. not powered. To retrofit one of these with an electronic version you need batteries because there isn't a completed circuit to run it when the heat/AC is "Off". When the heat/AC is "On" you could recharge them.
Best section for me .. wow .. the contained, restrained way in which Mr.Ive speaks these chiseled words out is powerful / emotional .. strong / vulnerable in one go :

" Steve used to say to me -- and he used to say this a lot -- "Hey Jony, here's a dopey idea." And sometimes they were. Really dopey. Sometimes they were truly dreadful. But sometimes they took the air from the room and they left us both completely silent. Bold, crazy, magnificent ideas. Or quiet simple ones, which in their subtlety, their detail, they were utterly profound. And just as Steve loved ideas, and loved making stuff, he treated the process of creativity with a rare and a wonderful reverence. You see, I think he better than anyone understood that while ideas ultimately can be so powerful, they begin as fragile, barely formed thoughts, so easily missed, so easily compromised, so easily just squished. "

<edit> This segment made me literally tear up,, his entire speech.. it is clear that they were best friends. </edit>
In C you could replace

if x in WHITELIST

with

if ((x >= '0' && x <= '9') ||
(x >= 'A' && x <= 'Z') ||
(x >= 'a' && x <= 'z'))

which I suspect would be much faster than any hash-table implementation. Also I believe that should work for UTF-8 as well as ascii. I realise that this makes it harder to expand the whitelist. I'm not very familiar with python, is there something similar that could be done?
Great example of taking on an existing market that needs an injection of innovation. Programmable thermostats are easy to install (I installed mine years ago) and can save you lots of money if used properly, but their UIs are terrible. Lots of buttons and inherently unintuitive. I'm surprised I remember how to reset the filter replacement alert.

There is a market need certainly, but is their target market big enough to support the business? I think if you can encourage users to adopt these based on the cost savings then the odds will be better. Lots of home owners will be interested in saving money on their utility bills. Just make sure the UI and features enable users to make efficient use of their HVAC systems. There will definitely have to be a campaign to educate consumers as to why they need this product.
A bit off topic, but NPR chrome app is awesome! http://www.npr.org/webapp

If anything, new Chrome store design makes things more discover-able than before.
You could argue those languages are not very clean, at least syntactic-wise.
I don't think it makes much sense to count DRM store subscriptions (here 'app downloads') on Android and iOS, since the two platforms have such a different approach to platform design (integrated on iOS vs. connected on Android).

For example, there is nothing similar to a 'Locale plugin' or a 'ADW Launcher Theme' on iOS, and there is no approval process on the most popular Android store.

There is only one DRM Store on iOS, and on some Android devices there is no Store at all.
The same thing that kills a lot of cool things - regulations.

Brazilian mainstream media is also very partisan-biased, though they won't ever admit it and always strive to come out as politically neutral.

While there's a left-centrist party in office, not one positive news is to be shown in mass media vehicles, even when the president receives an international award, the people are kept in the dark about it and you have to follow alternative news to be informed. This discrepancy has even been reported in international news before.
It wouldn't seem so in this case. The people may very well feed wikileaks, but only with the permission of the banks, and if the banks feel that it is not in their best interest to allow it, they won't abide. I would like to say, however, that I don't think this is right, I just believe that it this is how it is. In truth, Wikileaks (whether you agree with them or not) being silenced by world powers makes any sort of change/revolution seem a remote possibility.
Working At Home Jobs and What To Watch Out For
My favourite quote from his talk about 'Elephant 2000': "In 'Elephant' the programmer would write nothing about an array or database for storing reservations. Arrays of course would be necessary but the compiler would invent them."
Anything you want. Preferably something you're interested in. The subject itself is unimportant - the facts you'll be learning will be out of date by the time you graduate almost regardless of the course you pick. The skills you need to learn are self-motivation, self-reliance, working in a team, and how to recognise what's going on around you (in terms of both spotting opportunities and recognising when things are going wrong). You can learn these skills on any course.
Wait a minute: the amount of information in a typical Jazz chart is vastly inferior compared to the information typically found in a score for a classical piece. This is because in Jazz, much more is left to the discretion of the musicians. So, it is quite difficult to correctly compare the two, since they don't have the same uses.

About the double sharp, it often has to do with tonality. Classical music is typically more tonal than jazz. The sharp is needed when you temporarily change tonality, and some tonalities just need double sharps then and there –Gsharp dur for instance. If you wrote the natural note instead, it would not convey the intended tonality.
I wonder if this applies to my old nexus one

IBM has a mechanism for doing exactly this. When someone submits an idea for a possible patent filing, if the idea doesn't have enough value to spend the time and money filing a patent application, the proposal will get published in a public database of ideas (with some kind of notarization), specifically to serve as prior art to make sure nobody else can patent it either.

At least in theory, patents have to have a description sufficient to allow someone to create the thing in question. You can't patent any of the things you mentioned unless you specify more detail on how they work. (Insert the usual disclaimers about the lack of diligence in enforcement here.)

Tips to Select a Good RV Storage
You are a 19 year old web developer who finds college hard? Then they are not hiring you because you are the second coming of Richard Stallman. You are being hired as just another warm body, easily replaced or downsized. When you get the axe, you will have no job and no enrollment. Whoops.

Tell them no way, you are committed to earning a degree. Higher education is valuable to you, so it's part time or no time. Do not be apologetic or sheepish. Do not blather on with explanations. Leave a silence for them to fill with compromise. If they truly like you, or if they are desperate for a warm body, they will likely compromise on part time or summer work.
Tabula rasa says there are no real switches. Grandparent is saying that there are, but we don't have to obey them unthinkingly.

Not all switches in the human brain are for stuff that's as nice as caring for children or falling in love, so you might still want to think twice before unquestioningly endorsing their superior wisdom over conscious thought.
Sounds like you needed to charge more. :)

You wouldn't necessarily want to set the standard price significantly higher, since at some point you'll trip a large number of people's thresholds for "too much for a hat". However, you could leave the price and queue system in place as it currently stands, and introduce a higher "queue-jumping" price. Effectively, that would make the slot a coupon, but the concept of a queue seems much more appealing (especially to a gamer audience).

Achieving Mental Health Through Anger Management
No, I don't think so. Go to the extreme and think about leaving for a week or a month - it is quite clearly more efficient to let it cool and then warm it back up again. On a shorter time scale, your house will lose heat at a faster rate when the temperature differential to the outside is higher, so letting the house cool will reduce the rate of energy loss over the time period the house is cooler. The amount of time you are able to leave the heating off while the house cools will compensate for the higher load when you need to heat it up again.
Nice idea, off by an order of magnitude on the price. :)

A HTML5 game that crashes every browser - browser makers, please do better
Hi HN,

Not sure where else to best reach the browser people, but I've made a little space shooter HTML5 game using canvas 2D. Here's the URL:

http://www.scirra.com/labs/spaceblaster-webapp/

Arrow keys to move, hold space to shoot, press shift to fire rockets.

This game crashes every single browser on Windows 7 64-bit. I've had it crash on Chrome 14.0.835.202, Firefox 7.0.1, Internet Explorer 9.0.8112.16421, Opera 11.51 and even Safari 5.1.1 for Windows. Sometimes it crashes within 30 sec, but it almost always crashes before completing the game.

Please either tell me what I'm doing wrong, or fix your browsers. Everyone loves HTML5, right? So please make sure it works properly, because current browsers just don't seem to be good enough.

It always amazes me when people can dismiss academic papers -- the result of (at least) several weeks of work -- with a glib comment uttered anonymously, and no support given.

Have you read the study? If not, you can find it here: http://www.cs.siue.edu/~astefik/papers/StefikPlateau2011.pdf
There seems to be a number of "studies" with a ridiculously low number of participants (here, 18), from which "scientists" (actually, students) try to draw conclusion from quasi-random, statistically insignificant results.

Thousands of people learned programming using perl. This is much more significant than this ridiculous study (randomo language? quorum? give me a break would you?).

Fortunately, at least this poor-piss stuff won't make the headlines, like too many such ridiculous studies run on 30 students do (remember lately "women wearing make-up appear more competent", augh).
I don't like the contrived 'good sir' type of stuff (from reddit as well), but a demonstration of the full power of this language, from time to time, can be fun and creative, if it doesn't distract from the point.

What performance gain could be had from using cStringIO as described here:

http://www.skymind.com/~ocrow/python_string/

It seemed like the concatenation was the primary bottleneck in this case.

Also, its worth noting that percentage gains on performance have huge cost savings on infrastructure at scale. That's why blogs like this are valuable because the user experience improves while the cost to provide it is reduced.
"European solar radiation"? How much is that exactly? I'm pretty sure the radiation levels where I live (Portugal) are much higher than in Scandinavia.
No, there is no "stiction" with thermal loss. It is most efficient to not add any energy (heating or cooling) when you are not at home. That is as long as you do not mind it being too hot or cold when you first get back home.
This also clearly reminds me of one of the uses of perl. It's nice to use for prototyping something that can be implemented in ANSI C when necessary.

I have read the study which is why i made that comment. In fact, i've even contacted the author to gain more details about how they selected code samples to serve as learning aids and how all the other code samples looked like.

Additionally, i am not anonymous. Google my name and you will find all about me, including, if you look for longer than a minute, my full name and address.

Lastly, there was no need to give support in that comment by repeating what others and myself have said copiously all over the comments here. This was my main post towards that. Feel free to argue it: http://news.ycombinator.com/item?id=3153249
There were 18 frigging participants to the study, for chrissake! You can't get any meaningful statistical data from such a ridiculously small sample!

The methodology may be sound, they may be good students and deserve a good grade, but there are absolutely zero conclusion to draw from this paper except for the fact that it may be valuable to make a larger study.
