Yeah, that's my thought. Think heat exchanger, not heat engine. If you managed to get your input water at 10C from the ground up to 30C, you'd have very little left to do before it's usable in a shower. Either way, the thermal mass of the flowing cool water will definitely improve the solar PV efficiency and lifetime.
> specially when you take in consideration all the undefined and unspecified cases in C and C++.

That is an odd way of putting it. Aren't undefined/unspecified behaviors allowed to be implemented in whatever is simplest for the compiler if it prefers? Sure many modern compilers leverage them to expand the power of their optimization engines, but that isn't really a language difficulty case.
Perfect all depends on what you're optimizing for.

It simply means that Google and Apple has agreed to stop all current lawsuits against each other (Google still owns the patents that Apple filed lawsuits on) at the moment.

These lawsuits can restart any time.

Apple and Google promises to work together on certain patent reform areas. IMO, that's most likely related to IP trolls, those two companies are in the top three list of companies constantly getting sued by IP trolls.

I also found http://blockcypher.com to be quite nice. In addition to the blockchain API, they also have APIs for creating transactions and even provide web sockets and web hooks. They do not host the wallet so you do not have to share your private key with them. They will create a transaction for you and you can then sign it with your private key. This is a good gateway for developers into the bitcoin system. The alternative is running bitcoind to download the 17 gig blockchain and then start coding. This provides instant gratification for developers to get started.

At the other side of the table as a recruiter. Most people that aren't interested, state that they are working on critical projects / something incredibly interesting. Very few are the ones that state money is the main motivation. For highly skilled workers negotiating higher pay at their current company shouldn't be much of a problem if approached correctly.

One of the reasons employers want people motivated by the work is precisely because they will be harder to be lured away by pure compensation.

Side Advice: When interviewing, don't say the reason you want to work with a company is just because it's a prestiges company or higher pay. You are interviewing with your peers, not the HR department. Last thing teams want is to hire a person that isn't interested in their projects in the slightest.

There exist several organizations which have the general template: Hello, academic high achiever. You've spent your entire life in a series of meritocratic competitions. You're socialized to seek the validation of decisionmakers above you, by hewing exactly to their published rubrics. This is gives you a powerful sense of self-worth, brings you status with your peers, and makes your parents feel like you've finally made it.

And now you're graduating from undergrad. And there's a wild, crazy world out there. And many processes in it are not judged by meritocratic competitions.

(I rush to say that I fit this to the nines after graduation.

As a child, I dreamed that I would grow up to a world where genetically modified organisms were the key to sustainable agriculture. Plants that eliminated the need for petro fertilizers by enriching the soil like clover and were resistant to disease and insects. Instead I somehow ended up in this Bizarro World, where Dr. Evil runs Monsanto. Where they’ve turned large tracks of fertile land into a barren, sterile wasteland that can only grow their GMO crops.

How can we turn the tide back, so that government serves the people instead of big corporations? You’d think the “corporations are people” would be a wakeup call, right? I’m glad to see there’s still people out there like those at Glowing Plant that see the potential in this technology before the world gets fed up and just bans GMO.

Not terribly, at first glance. Crypto generally uses fields with no subfields and large characteristic, whereas these attacks seem to generally be limited to fields with subfields and small characteristic.

For the time being, it only applies to elliptic curves. However, the curves in actual use are over fields of large characteristic, so this result does not break them.

Obviously, any advance in understanding the discrete logarithm problem may be a step forward in breaking elliptic curves, but as far as I know, this is not a reason to change anything for the time being - at least for non-cryptographers.

Have you tried using Christoph Gohlke's pre-compiled binaries[1]? Here's the list of libraries I have installed [2].

Also don't customize any install paths; leave it everything as default (e.g., C:\Python27). I've long gave up trying to keep my root folder under control; now it's a festival of Ruby, MinGW, Vagrant, etc.

This is the only way to install python libraries under Windows without pulling your hair out. Any other way is truly a nightmare. That's why I use Linux whenever possible for most of my coding.

Problem is, too many cheap phones are still shipping with Android 2.3 because the manufacturers just don't care.

Event that is hardly enough. There should be a physical (well virtual physical) obstacle towards launching a high stakes command.

The system should be able to assess the scope of a task, and ask you to confirm 10 times if it has to, in blinking red dialogs, to make sure you really want to do what you are doing.

Of course, it's crucial that "clicking 10 times" is not the default behavior for any trivial action. Or boredom and the subsequently formed mechanical 10-click habit of the operator will kill the effectiveness of this approach...
I think the problem with that approach is that if you want to play online then everyone needs to be running the same client version.

This actually came out about half-way through last year. It's a good attack on DLP-based cryptosystems, like ECDSA and ECDA when they use small-characteristic fields.

Most EC crypto in use uses large-characteristic prime curve fields (often abbreviated as GFp) and is unaffected by these attacks.

Small-characteristic GF2^m curve fields seems a little more popular in embedded hardware, but I don't know any details. Relatively little software uses GF2^m curve fields either, though a notable exception is Bitcoin (I have no idea what this result meant for them).

Notably, the EC used in SSH and common SSL deployments use GFp keys and aren't affected by this result. It does make one wonder whether the DLP will fall more generally - it is only believed to be "hard" and AFAIK there is no proof that it is.

I write HTML5 mobile apps and I've written native mobile apps and native lets me craft the best possible experience. HTML5 is pretty great in a lot of contexts, but I wouldn't go so far as to call is superior. It might be a better fit for your project, but it doesn't make it superior in a general sense.

Just remember that the web runs on top of a runtime called a bowser and you will always be at the mercy of said browser for a lot of functionality. Without native code, you don't have access to the services that make mobile phones more special and interesting than just a really tiny browser screen with a always on internet connection wherever you go.
Can you elaborate on why you view this as not being good for their users?

The functionality will probably be integrated into Google Translate (or perhaps Google Goggles and Glass) and the Wordlens app will disappear, but I don't see why that should be a bad thing. Is it because you fear Google won't deliver the same functionality on iOS, or is there something else that I am not considering?
And then there’s dual SIM (or even quad SIM). It’s a feature
that’s really popular in Asia and Latin America where people
might use one network for a local call and another for an
international one. That’s largely something MediaTek drove,
but now it’s in the Moto E, which also has a feature called
SmartCalling to help people set up and swap between SIM
preferences and automatically configure access point names.

>I think it is helped by having a FOSS reference compiler (GNAT)

It should be noted that the free version of said compiler may only be used to produce software released under a GPL compatible license. This is unusually restrictive and rules out Ada for most people right away.

It is either Free Software only or an expensive commercial subscription to AdaCore's services. I mean the "expensive" is a guess, but given that they do not list prices on their website but ask you to contact their sales department, we can assume they are far from cheap.

In a world where you can develop commercial, closed source software in all popular languages using free tools this seems anachronistic. I understand that AdaCore needs to make money somehow and this is probably the best business strategy for them, but still, it seriously limits the appeal. The appeal of Ada in general too, because it seems there is no (truly) free, modern Ada compiler.

Interestingly enough the situation seems to be similar for most of the failed languages of days gone by. If you look for implementations you only find DOS era stuff and X thousand dollar "solutions" which milk the enterprise/government legacy code market.
Didn't the Swiss vote on basic income recently? Seems like it would be a much better alternative. Such a high minimum wage is likely to discriminate against the very poor by favouring automation and reducing demand for unskilled workers.

Well, each time a new article claiming that HTML5 has better user experience (as stated by this article "Speed and user experience"), i can't find an app that feels just right made with HTML5.

Just can't find any HTML5 app that feels better than a native app. It doesn't even feel the same, at least to me.

I've seen great apps, with great user experience, but all of them could be a lot better if they were native.

Just my opinion, no disrespect to anyone, and i'm not saying i won't develop an app with HTML5, i just think that we just can't compare them, so we should stop comparing them.
This is basically spam.

While many things in the article are just bogus, what tickled me the most is the one about how html5 helps design innovation. Hardly! In fact HTML is a terrible language for designing good ui's. The only reason we do it is because of its pervasiveness.
Extraordinary claims require extraordinary evidence. Meanwhile, let me keep thinking native gives better results...
