"In cooperation with strategic battery manufacturing partners, we’re planning to build a large scale factory that will allow us to achieve economies of scale and minimize costs through innovative manufacturing, reduction of logistics waste, optimization of co-located processes and reduced overhead."

I guess that and also securing the supply chain for themselves as the rest of the car industry starts/continues to compete with them for the battery supply.
Changed. Thanks for pointing it out :)!
To be fair, you get much bigger yards when you get out of the Bay Area and out of urban California and into more 'middle America' kinds of places.
The first rule of programming is there are a thousand kinds of programming.

All of the great programmers I know got that way by repeatedly thinking up a cool idea they had, researching how to do it, and winging the rest. All you need is Google these days.

Though, of course, schooling can accelerate the learning by teaching you the mistakes of your elders so you can conveniently bypass them.
Thanks for the links. Sadly doing mori benchmarks like this does't say as much about the performance of ClojureScript data structures than it does about mori specifically - in many cases you are likely just benchmarking multi-arity function dispatch overhead because you don't have the ClojureScript compiler doing direct dispatch for you. If you want accurate benchmarking of ClojureScript data structures you will need to write the benchmark in ClojureScript for the time being and call them from JavaScript.

Also benchmarking in Node.js doesn't reflect the wide variance you find in JS engines. In several cases in the past we avoided V8 specific optimizations because it punished other JS engines.

UPDATE: I also ran some benchmarks and I can't replicate the perf degradation as the size of the hash map increases. My suspicion is that the random key generation may result in many hash collisions w/ Murmur3 which would explain the dramatic perf degradation which is unlikely to occur in the wild.

Ionic is a framework that allows you to create mobile apps using Cordova. You write html/css/js and then use Cordova to generate platform specific code. This is what wiki has to say on "Hybrid" apps -

The resulting applications are hybrid, meaning that they are neither truly native (because all layout rendering is done via web views instead of the platform's native UI framework) nor purely web-based (because they are not just web apps, but are packaged as apps for distribution and have access to native device APIs).

The awesome thing about Ionic is that you have suite of cool widgets and components that are commonplace in mobile like the a header, sidemenu etc. (most of these are created using AngularJS directives). So instead of hand crafting the code for these UI elements, Ionic gives you a nice starting point to build such kinds of apps quickly and easily.

Ionic's toolchain is also delightful to use and much less intimidating than Cordova (or Phonegap) IMHO. If you're looking at building a mobile app which does not require esoteric native APIs and want it to deploy on multiple platforms - give Ionic a shot.
The best part about the Model B+ is the better power management. One of the huge issues with the older model is that it was super inefficient with power. Based on our initial tests (and covered in this article) they made some huge improvements in the power. This makes it much easier to power by alternate means (IE stick in a robot or power with batteries or solar). Pretty awesome step forward!
I cant't find either pricing or other hints of a valid business model anywhere. That makes me a bit wary to try it out - how long can ionic exist without income?
there could be an allowance for people to work on open source stuff, or a project of their own that has some value .if would increase beaurocracy a bit but its possible .
My first thought as well. This could be used as constant surveillance tool if Shazam chose/was forced to shared the uploaded data with GCHQ/NSA </paranoid-theory>

I assumed it was not because they only talk about "time spent practicing" surveyed from 88 different papers, which may include "practice" and "deliberate practice", and further down they write:

> She hopes to investigate such factors as basic abilities, age when starting to learn the skill, confidence, positive or negative feedback, self-motivation and the ability to take risks.

This doesn't seem to cover the introspective / deliberate part of practice.

Though, I asked myself: if practice is not deliberate, is it "practice" at all? If not, what should we call it?
Totally second this comment. The best advice for this sort of thing: hop in. I started by trying to read a few books. I don't think I learned nearly as fast as when I just tried to think of something I wanted to make, and devoted a few hours/days to building it.
Can confirm that they're pursuing this business model: particularly to see what TV ads you're being exposed to. Coverage from existing sources is panel based with low sample sizes that do not extend well into more targeted research.

Drifty (creators of Ionic) recently raised a million dollars in funding.

With the additional funding, the founders plan to now focus solely on developing Ionic further, with plans to improve gestures and animations, plus roll out mobile services in 2014 that would make using Ionic a viable alternative to native app development. Areas of focus include things like analytics, notifications, and testing service. These would help the company generate revenue from its free platform.

But to implement that, you still need some administration to work out who's eligible for welfare and who needs to work. Basic Income schemes potentially eliminate this requirement.
Ah, I see. I'm not sure I'd call it zip-with, but it's definitely familiar and useful. Scalding calls it map-to[1], and Trident's `each` can work this way as well.

Not sure if your comment was a general statement or aimed at the author of the article (Paul), but for the record Montana has "real" winters. I lived a much similar life in rural Utah for many years, doing many of the same lifestyle optimizations that Paul is engaged in.

I don't know what Paul's house is built of, but mine was solid brick, which probably matched the structure and function of the dense brick/cob building of Europe. The thermal mass was a blessing, as my only form of central heating was wood/coal-burning cylinder stone in the center of the home. In the dead of winter (lows often in the -5 to -15F range at night), a short, intense burn first thing in the morning would charge the house, with minimal burning during daylight hours to maintain a comfortable temp around the core living areas (55-to-65F). Just before bed, load and tweak the stove for a long slow burn. By morning, even on the coldest of nights, the temp never dropped below 45F.

As for his heat-the-person-not-the-room method, that's an obvious, old technique which I applaud Paul for using. For me, a thick down comforter on the bed pre-charged with heat via old-fashioned hot water bottle an hour before (they have nice, newfangled silicone models these days) was all it took. The water was, of course, heated on the wood stove.

During the day, wise clothing (layers, wool, hats) and space heating made the place livable. As did the occasional bout of labor to build up head (an old saying is that chopping wood heats you twice). Yes, there is also some acclimation that takes place. Several years after abandoning the lifestyle, I still cannot tolerate indoor temps much warmer than 70.

Frankly, given that Paul has a rocket mass heater (much, much more efficient than my stove ever was), I am surprised he needs much in the way of spot-heating. Unless his home is of stick/frame construction.

Ask HN: Web-based SaaS products with in-app purchase-style revenue model?
Mobile apps that are free to download and which generate revenue through in-app purchases commonly appear to be, or are reported as being, more financially successful than mobile apps with an up-front cost. I don't have any sources to quote there, it just feels like a current trend based on articles posted to HN.

I'm considering if such a model can be successfully applied to my web-based SaaS startup.

My product offers a limited free tier and a set of premium tiers supported through monthly paid subscriptions.

The product carries out automated web testing and presents the user with results with the scope of testing, depth of testing, and permanence of the results determined by how much the customer pays. That's an intentionally abstract description as this topic is not centred on product itself.

I've hypothesised that, for some users, a monthly paid subscription is impractical due to occasional use - the product may provide value on a handful of occasions throughout the year but not on a regular-enough basis to warrant a monthly subscription.

I'm contemplating a revenue model in the style of in-app purchases in addition to what is already in place.

I feel it is a good fit to how my product works - the user could carry out, without charge, a website test and then choose to pay a one-off free to gain full access to the results.

I'm not aware of any SaaS products that use such a revenue model. This by no means implies that there are none. I'm a very small sample size.

I'd like to ask for examples of where an in-app purchase-style revenue model has been successfully (or unsuccessfully!) applied to a web-based SaaS product as well as to seek comment on the idea.

Are you aware of such a revenue model being applied in this way? Have you seen it work? Have you seen it fail?
Can you expand on that please ?
I think social trading apps / websites are the way forward - get friends helping each other with the learning curve, and P2P transactions well away from centralised exchanges.

I built CoinTouch to find friends of friends that trade crypto currency. It's been live since February and has 1700 users now.

There's a critical mass on CoinTouch such that most new signups see orders within their (two degree) social network. FB and Google+ are supported, and all transactions are P2P. No fees.

F1 Tech Is About to Make Buses More Efficient
I'm in a (very old) brick building in brooklyn and I have never heard my neighbors. I assume they haven't heard me either since I play my music at all hours and pretty much whatever volume I please. Honestly, usually my roomates on the other side of the apartment don't even hear me. This is definitely more related to new cheaply built structures than sharing a wall. I do realize that there are pros and cons to suburban living as well, but noise through the wall was your only reason.
It's so hard to get people to understand the importance of the current Job Expectation not being relevant in the not too far distant future. Working as an old fashion wage-slave will be overshadowed by the coming wave of automation. Tens of millions of redundancies will occur just from self-driving cars. The notion a Job Guarantee will be outdated (if it isn't already), not to mention impossible & quite possibly harmful for technological progress.

I reckon people will become like you, working to improve the systems that support our infrastructure. Where the work of one provides for many. Where schooling isn't some odd prepping for ye old industrialization period but directly launching us into reinventing agriculture, energy grids, transportation, space exploration, production & knowledge. Where we will become not to a resource economy or a services economy. But a research, knowledge and engineering (automation) economy.

When everyone's expectations of conventional capitalism dies down. We will truly transform as a civilization.
cheap apartments are also poorly air-sealed, which means they're already losing a great deal of their heat through air leaks. An extra one-time 10% turnover won't make a puddle of difference.

In winter in particular, the rate of through-roof air leaks is also greater when temperatures are warmer due to the stack effect. The author is completely wrong on this front - it's far better to let your house cool down and then re-heat.

The only time this isn't true is if you have a two-mechanism heating system such as a heat pump with resistance heat backup, where a large temperature swing invokes the more expensive resistance heater. The author doesn't.

Life as a Startup: the Pitch
It's not the companies though, is it?

(Mill team, so biased; thanks for the chance to pitch ;)

We are a DSP that can run general purpose code.

Traditionally, to run general purpose code fast you needed an out-of-order superscalar architecture, as all the x86 and RISC cores are these days.

DSPs have substantially better performance and substantially better efficiency, but have traditionally been ineffective executing general purpose code (such as the web browser you are using to read this).

The Mill is a synergy of lots of small breakthroughs that together deliver significant improvements to general purpose single threaded code.

Its been held that cores have stopped getting faster. We're faster.

And we have similar as yet not filed improvements for multicore too.
Highly recommended: Aztec codices, especially the ones with pictures. Looks like modern psychedelic art of some kind but is in fact made centuries ago, sometimes by their priests.

For the rest: it's amazing to see how back then simply writing was way more of an art than it is now. It's no exception that the writer would use 2 or more colors even for simple text, for example just to highlight capitals. Don't think I have ever seen anyone doing that in the present. Also the maps from those days often look like sceneries from some fairytale with nicely drawn castles etc. Not like your average roadmap :P
It can, and it does. Well, it just did for me anyway.
Have you considered going along to a couple of meetups around the sort of technology you're interested in working with? There are a lot of wordpress meetups around the world, for example. Or maybe even going along to a hackathon, if you'd like to try something a bit more deep tech? Those are both pretty low risk ways of meeting some other people who are into programming, see if you feel comfortable with the sort of work that gets done? It's also a good way of getting yourself known (leading to possible job offers).
You shouldn't worry about it. I worked with a guy that was did construction for at least 10 years before he went into a tech field. If that massive career shift didn't impact him, a few months while you finish up your self study definitely won't. I believe it show initiatives to a potential employer that you're trying to improve yourself and took a pretty hard job in the meantime to pay the bills.

"Totally free!

We want to help more web and mobile developers become hybrid developers with Ionic. Having great tools like Creator will lower the bar for getting started with mobile development in general, and we love that!

To achieve this dream, we have decided to make the Ionic Creator 100% free. While we might charge in the future for heavy usage, we will always have a free version of Creator available, so you can quickly build Ionic and Cordova apps."
Anyone know what the timer is? Could it be a timer for usage per day? I can't seem to find anything about paying them for it.

Responsive Images – There’s a Service for That
Yeah, I should have made that clearer. It's not a Raspberry Pi. Obviously, if any of the differences is a showstopper for you, don't use it. Personally, I'm happy with my Raspis and I have no experience with the Bananas.

But "absolutely different"? And then putting the name of the Banana in scare quotes? That's a purist's perspective.

Judging from the comment I was replying to, it seemed that the poster was less interested in an absolute clone of the Pi, but was in fact looking for something Pi-like with more I/O power.

That assumption may have been wrong or not, who knows. I just felt like putting it out there as an option, which judging by the moderation wasn't warranted. Sorry about that.
The Company Keeping Your Favorite (And Least Favorite) Websites Online
Can you say anything about where you are on the path towards silicon implementation or is it all still under wraps?
Thats how they sell it, but the real goal was very different. To cite our former Chancellor Schröder:

" Wir müssen und wir haben unseren Arbeitsmarkt liberalisiert. Wir haben einen der besten Niedriglohnsektoren aufgebaut, den es in Europa gibt. Ich rate allen, die sich damit beschäftigen, sich mit den Gegebenheiten auseinander zu setzen, und nicht nur mit den Berichten über die Gegebenheiten. Deutschland neigt dazu, sein Licht unter den Scheffel zu stellen, obwohl es das Falscheste ist, was man eigentlich tun kann. Wir haben einen funktionierenden Niedriglohnsektor aufgebaut, und wir haben bei der Unterstützungszahlung Anreize dafür, Arbeit aufzunehmen, sehr stark in den Vordergrund gestellt. "

Translation by Google:

" We must and we have liberalized our labor market. We have built one of the best low-wage sectors, which is available in Europe. I advise all who deal with it, to deal with the realities apart, and not only with the reports on the circumstances. Germany tends to put his light under a bushel, even though it is the worst thing you can actually do. We have built a working low-wage sector, and we have in supporting payment incentives to take up work, provided very strong in the foreground. "

s/supporting payment incentives/if you do not accept the 1 Euro job, we cut your social security payment/

The result of this wage dumping can be seen in the Euro crisis. People around Europe become unemployed, and those states collect dept, as they can no longer escape German wage dumping, by lowering their currency.

This just shows me that Tesla is able to execute. The Gigafactory, opening up patents, rapidly growing charger network, and the eventual $35k Gen III tells me they have tons of potential in the future.

Tesla is thinking big. They want everyone in the world to eventually have a electric car. I think they will own a significant share of premium market after they release the Gen III.

However, they will be cars that people will desire at a cheaper price point than the Gen III, from different manufacturers. Also some people love certain car brands regardless of anything else, and mostly will stick to those brands. It will be great that those other car brands will be able to more easily make electric vehicles.

Those electric cars from other manufacturers will most likely have a Tesla battery and charge on Tesla charging station. I think this is true disruption.
Rackspace Developer+ Program
I doubt we will all become engineers, scientists and technologists working on reinventing agriculture and energy grids in any foreseeable future (quite possibly any future at all). The wave of automation you're talking about has already been happening for a long time and is the reason we live in a services-based economy. We automate (and outsource) manufacturing, but increase the direct human-to-human exchanges called services.

Starbucks provides a startling example: making a coffee was automated a long time ago, but people still would rather have another person make their coffee. I'm pretty sure the same is true about hairdressers, stylists, nurses, personal trainers and glacier guides.

(Note: I'm not advocating a policy or direction, merely stating an observation)

It's the countdown until the mic switches off again. You may not want to keep the line open all the time, it may prevent your computer from going into power saving mode (not sure), and Shazam probably doesn't want everyone to hit their servers constantly either.

But if you switch it off and on again the timer starts anew, so it's not a per-user limit.
http://audentifi.com does this :)

I must have skipped over the article as I assumed it could pick up on internal audio. Seems like an oversight...
I'd like it to function relatively close to how the actual calculator works as I'm use to using it that way. CLI would be cool too but I'd imagine that limits the range of users who would know what to do with the calc who may have a use for it.
Well it's definitely picking up what I'm listening to on both Spotify and Youtube with my headphones on.
No speakers on my desktop sadly.
Not really. The app only picks up music from ambient mic input. Your app looks like something I've needed for a while though!
