Comparatively weak single-threaded performance, weak GPU performance, constrained memory interface, high power consumption when not running only the companion core.

Tegra 3 isn't terrible, but just like previous Tegra chips it was so hyped up before launch and again turned out to be among the weaker ARM chips of its generation. Exynos, Snapdragon S4, Apple A5 (and now A6) and OMAP 4 beat Tegra 3 on everything except synthetic multi-threaded benchmarks (because it has 4 cores, obviously).

He speculated on the options Apple had for the iPhone 5 SoC, and speculated wrong. No big deal, it happens to every tech website or blog that tries to predict future products. Now he has some tangible evidence about the nature of the A6 core (the fact that XCode now has build profiles for ARMv7s + VFPv4) and supposedly got confirmation from someone in the know that the A6 is a custom design. Seems like a safe bet this is right to me.

If you list the courses like I did in my project last year: www.textbookcentral.com.au, you can get lots of visitors searching e.g "Math141 textbooks" from search engines.

I firmly believe that the human brain is incapable of basic mathematics.

When I add two numbers, say 145 and 394, I have memorized a few rules and tricks that let me break that down to something like 1+4 (hundreds), 4+9 (tens), add one to the hundreds, etc.

Or, I might figure out that this can be decomposed to 150+400 - (5+6) or something similar.

At any rate, I decompose the problem to sub-problems I have memorized the answer to: adding single-digit numbers.

This is basically the same process as programming. Are we asking whether people are "incapable" of mathematics? No. But we know that some people are way better at language than math. And that is all there is to it.
Type punning through a union is explicitly defined to work in C99 and C11 (footnote 95 in C11):

> If the member used to read the contents of a union object is not the same as the member last used to store a value in the object, the appropriate part of the object representation of the value is reinterpreted as an object representation in the new type as described in 6.2.6 (a process sometimes called ‘‘type punning’’).

Please don't help spread the myth that compiler writers can break this idiom. That said, I use memcpy in my own code.

What, how's programming like writing stories? Writing multithreaded database access is exactly like writing a story about a school of wizards, right. The only thing these have in common is that you use a keyboard to type them.

Like with many other professions, some people are just more cut out for it then others. Yeah I know we're all equal.. but the truth is we're not. Programming certainly seems like one of these professions.

Y won't they make this, but in the light bulb use the lan over power, then plug a lan over power adapter in where your router is.

But then you have the problem that every lightbulb is a "computer" on the power network and I don't know how that would work.
If the people like Atwood who argue that some people just can't learn programming are to be taken seriously, then by the same argument and same types of evidence, there are some people who can't learn science, or math, or reading, or how to speak or write. Because what the evidence is showing is that some people have difficulties learning some topics or take longer to learn them, and in many cases have misconceptions that make it more difficult to teach the topic to them effectively. And the evidence shows that traditionally taught courses (lecture/memorization based - taught by people not trained in more effective teaching methods like active learning) often do not significantly impact conceptual change of such students.

The Bornat & Dehnadi Goats & Sheep paper is interesting in showing that we can diagnose students who have significant misconceptions or lack of knowledge needed to learn programming (see similar research on concept inventories showing the same thing in a wealth of other subject areas). Beyond that the strongest interpretation would be that students with misconceptions are less likely to succeed in traditionally taught CS courses. Not that such students can NEVER learn the topic and NEVER be a programmer. I wasn't surprised to see their research wasn't published (although it is so easy to get such research published - especially when the peer reviewers aren't trained in educational research and learning theory, either). But a line like this would never stand up to peer review by people who are even remotely familiar with research in computer science education: "change the language, change the application area, use an IDE and work on motivation. None of it works, and the double hump persists." There are decades of studies showing various strategies that DO help more students learn and better understand programming and computer science concepts. Just because Atwood and others are unfamiliar and ignorant of such research doesn't make their opinions more right.

That has to suck for Leah, especially since there's definitely a worthwhile product somewhere in the team realtime communications space; maybe grove.io wasn't it, but I find team IRC and IM to be incredibly useful, and if there were a good way to combine the two (and some kind of wiki/logging/etc.), with security, it would be great.

It would be cool if there were a way to put systems in escrow in case a company tanks or pivots, to protect users. The time to fund and set that up is during development/normal use, not once you've run out of money and decide to shut down, though.
I'm not sure. We don't have a charismatic like Putin leading, law in China seems much more defined than Russia. I believe the corruption will eventually be cleaned up and we'll get a well run police state like Singapore.
The internet has led to an arms race of exclusivity, giving rise to such phenomena as hipsterism, un-google-able band names, private (offline mediated) online communities, etc. These are merely the growing pains of a culture which has not yet acclimated itself to total, ubiquitous access to information.
If you take a step back, "kickstarting a hackerspace" sounds like a phrase people might make up ten years from now to make fun of our time's silly jargon. Tubular to the max!
My experience was of spending about ten years writing terrible code, and slowly building up ability. I think I am quite good at it now, but am probably just kidding myself. A lot of people just give up at the first hurdle. I doubt they lack the ability, just the drive. And if someone starts a CS course and has never tried to code they probably don't have the desire to learn.

Ask HN: Why doesn't more failed startups Open Source their product?
What's stopping them? Code quality? Copyright? Or maybe they just don't care?

I've seen a lot of annoyed customers in the threads lately complaining about not going to trust small startups again. And I don't blame them.

I'm pretty certain products like Sparrow, Grove.io and more could really flourish as Open Source projects, but instead they're left to die...

Would really like to hear from someone with a previously failed startup.
> It's a little troubling to me that he has to work for Google (as much as I love GOOG their work is not exactly stuff of Bell Labs: how can we serve more ads?)

google has some very interesting systems problems to be solved that are almost entirely divorced from the fact that the monetary goal is serving ads, or even that the core goal is organising the world's information. the company is seriously attempting to push the boundaries of "how can we make large clusters of people, machines and networks more efficient and productive", and thompson's work on go is squarely in that realm.

I was pleased to see that you can use your existing switches. For the majority of cases I can't imagine anything more irritating than having to get my phone out, open up an app and find the right light control, just to turn the light on. It would definitely be convenient to switch all lights off when I go to bed though.

Coloured lighting seems a bit naff but maybe there are more subtle ways to use it than make your lounge look like a nightclub.
I think the following (quote from the article) is a very good observation:

"I suspect — and I don’t think this is nostalgia — but it may have been able to become kind of a richer sauce, initially. It wasn’t able to instantly go from London to Toronto at the speed of light. Somebody had to carry it back to Toronto or wherever, in their backpack and show it, physically show it to another human. Which is what happened. And compared to the way that news of something new spreads today, it was totally stone age. Totally stone age! There’s something remarkable about it that’s probably not going to be that evident to people looking at it in the future. That the 1977 experience was qualitatively different, in a way, than the 2007 experience, say.
Such a shame :(

> Beyond that the strongest interpretation would be that students with misconceptions are less likely to succeed in traditionally taught CS courses

You don't even have to go that far. When I tutored people in programming (years ago at university I tutored fellow business studies students for 2 years), I found that if I could identify their misconceptions and work through the misconceptions with them that they could indeed resolve their challenges with programming.

At best all these papers can say is that these people were unable to build an adequate mental model of programming by themselves (yes they presumably had access to tutors but that doesn't mean the tutors were sufficiently skilled, or that they used the tutors). There is nothing to suggest that spending some time working on their misconceptions with them couldn't have changed that result.
A story can't be 'wrong' as long as the grammar is used correctly.

Sure it can, have a murder mystery where Joe kills bob in the library with the revolver. Only problem is Joe was in Monte Carlo, and bob was Austin at the time of the murder, and there is no twist remote tele-presence robot. Stories must have internal logical consistency for them to work well. Something like Oceans 11 wouldn't have worked if there had been concurrency issues.
My grandfather used to be an art teacher in his younger years and he found people would sometime claim they couldn't draw. He always responded that this was nonsense .. drawing involves making a mark on paper, and absolutely anyone can do that.

I think its the same with most things, anyone can program if they're given half a chance .. but only those with an aptitude are likely to excel.

correct me if i'm wrong, but qt4.x should happily coexist with qt5.x, providing all the legacy support the author might require. i'd be surprised if qt4 didn't get backported fixes and possibly even features from the 5.x branch, especially if a lot of popular apps end up still depending on it.
I think most of us get to a point where we finally figure out we're mortal, and each day is one less we have to live.

As a parent with two small children, I'm constantly faced with two paths: I could work really hard, the result being eventually enough money that would bring me more "happiness" (travel the world with my wife and kids, for example); or I could extract every memory possible while my kids are this age.

When I think about being on my deathbed and looking back on my life, what will I be thinking? Will I have wished I worked longer hours? Or will I have wanted more memories of my kids laughing with me?

There are a lot of things that people learn to do for themselves that no one would pay them to do professionally (cooking, minor home improvements, taking family photographs).

That doesn't mean those skills aren't useful. That picture of your kid might not make the cover of a major magazine, but Grandma is still going to like it just fine. That pot of homemade vegetable soup might not rate five stars in a restaurant guide, but your family is still going to enjoy it when they come inside on a cold day.

Most people are reasonably good at telling stories that are important to them -- telling your kid about what Great-Grandpa did in WWII, telling your buddies about the giant fish that got away...

A: Ironically, not much better than when I started this whole journey.

You're right, fun is cheap. So why spend my fortune when I could retire early instead? To live each day like its your last is to fear living. I will live my life assuming I live to a ripe old age, and will never fear to live another day.

To assume a healthy savings means I must be a miser is unwarranted. Most who are thin are not anorexic.
