Again it's easy to forget when you're in IT that most people are really not very bright at all. I mean, seriously not bright. It's hard to frame this in a politically correct way, but if you're using a computer now in a desk job, it's because you were already in the upper half of the IQ curve.

I'm not in IT. And honestly, your anecdotal reasoning is precisely what we don't need to be using as the basis for educational policy. I get that you're being "edgy" here with the jaded cynicism, but it's not exactly a constructive outlook, now is it?
I'm probably being too abrasive, but this isn't anecdotal. Half the kids at school just aren't that bright and they just don't even really need to be. You probably don't hang out with (m)any of them any more because they're out there doing stuff that doesn't need people to be all that sharp, while you're surrounded by clever people. I am aware that this sounds elitist but hopefully I can temper that by saying that many of the people I know are far, far cleverer than me, and the ones who are considerably so don't bother engaging me in social circles either. We are all stratified by our ability into socioeconomic levels.

As for why there aren't many women programming... beats me. It's seriously not as if they are actively or even passively discouraged. They just seem to harbour no interest in it on a general level, much like their remarkable lack of interest in joining the army, or their remarkable lack of interest in becoming surgeons (don't ask me why). The opportunity is there, and it is equal, and it's shoved under everyone's noses the same, at least in the UK here these days thankfully. So given that the opportunity is now the same - for all colours and creeds too in the UK - the lack of representation is most likely genuinely down to indifference.

I've been using Netty for quite some time, which is built on the Java NIO framework, but as I enjoy tearing down into the core of things, I'm wanting to learn how to write my own applications using  the Java.NIO package.

I've been looking really hard for decent study material on this, but it seems like anything pertaining to is either low-quality, or very low in quantity. Most of the 'tutorials' I find online don't explain anything, and while I can write a basic server by now, I don't really understand how it all comes together.

My over-all goal is to move my server-api to NIO from Netty with the next major release, but to feel confident enough to do this, I will need to do a lot of studying. I don't want to degrade what I have, but I also don't like the feeling of relying on someone else to do all of the hard stuff for me.

Any suggestions are welcome, would prefer if it at-least uses Java7, but J8 is recommended.

Price doesn't matter, only quality. I'm willing to spend $250~ on a good NIO networking textbook.

@bisl_ i won't say, that it will burn it, modern GPUs/CPUs start throtteling to reduce the temperature, if thats not enough, the Notebooks usually turn off to cool down. But throtteling and shutdowns are verry annoying, therefore you should read the tests. If it is a good Notebook, it's cooling system should be good enough to cool the hardware even in stress situations.
The GPU selection depends on the OPs needs, for max-settings in FullHD he needs a High-End GPU like the 970m or even 980m, for medium-high Settings the performance GPUs like 965m or even 860m should be enough. 
I highly suggest you do buy a Maxwell GPU, as they have better performance with less power consumption -> less temperature production. 
The Maxwell GPUs you can look for are the 860m (pay attention, there is also a Kepler-Version out there), the 965m, the 970m and the 980m. The 870m, the 880m and olders are always Kepler GPUs.

taking a weaker GPU to reduce power consumption is a pretty stupid idea. better take a big GPU and do not run it a max-settings/v-sync-off/4k-resolution. if you stress a TNT2 too long it will burn too.

nvidias maxwell architecture compared to kepler is better _especially_ for laptops.

This could be caused by the same reason: Businesses want good programmers but only want to pay for mediocre ones. And forcing kids to take programming classes in school is certainly not going to help improve the situation.

I disagree with your wording. We aren't talking about "forcing" kids to take programming classes. We are talking about **making it an option** in a way that it isn't yet, in the same way that we offer art courses, or music, or physics.

Are you still talking about elementary / primary school? If so then the system where you live is clearly very different to the system where I grew up, in which pupils didn't get any options until they were 13.

I have 50 bars in the bar diagram. I simulate 50 coin flips and if for example 27 of those are heads, I count +1 for bar number 27. That I repeat 1 million times (that takes about 2 secs, inefficient code, sorry).

Binomial Distribution p=.5, t=50

bitCount(gen.nextLong() >>> 14);

Rewrote LibStruct to make it capable of addressing the full range of 64 bit address space.

Quite possibly the most complex code I've written to this day. Roll Eyes

Where we can see this as code?

It's funny, my childrens ( 8 years old boy and 11 years old girl) wants to learn programming (seeing it's father to write code so often has an impact  Grin).
I will start to teach this week-end and i'm quite excited since i started programming when i was 7 years old in basic and i'm nostalgic ^^

I agree on one point, childrens construct their hobbies from which they can have access !!!.
If childrens are on an environnment (social, family, country, ...) that not help us to have discover the computer sciences, they can't discover they like it !!

But the problems occurs at a more general level ! when i see so many childrens and families around me without any contact with cultural things like arts, books, sports or even sciences, i'm very  afraid...
