"The C++ programmer must worry about the performance implications of abstraction."

This quote seems a touch odd when you consider just how much faster the C++ solution is. The Haskell programmer definitely does not get a complete pass on worrying about the implications of abstraction. Indeed, this seems to underscore that if performance is a major criteria, than language choice still matters.
So you're saying that Germans are equally prone to uncritically accept misleading media coverage?
I've seen this problem when using @font-face generators that remove font hinting to save space. Last time I used FontSquirrel's generator, I had to specifically unset the option to remove hinting in order to get the fonts to look right on Chrome on Windows.
> at best, it's an ambiguity that is not necessarily correct.

It is definitively correct.

You knew what he meant, you just wanted another jab to back up your argument. If you're going to be pedantic at least be correct.

Let's divide the world into 3 types of people.

Type A.
Those without enough mathematical knowledge to pick up on any
possible ambiguity. Who probably don't really know what median means in the first place (the majority of people).

Type B.
Those with enough mathematical knowledge to understand what he means by "average." (probably the majority of people on hacker news)

Type C.
Those who got just far enough in math to realize that there is a difference between arithmetic mean, and median, but not far enough to realize that average is a general term.

Which of those types are going to confused by the term average instead of median?
Perhaps they are collecting stats. We should check back later.
Before you say 'oh, Haskell is still only half the speed of C++', you should keep in mind just how insane the C++ code they had to write looks. The Eigen code they had to write is pretty nasty and getting it correct required some particular understanding.

In comparison, the performance they're getting out of Haskell is coming from comparatively mundane, easy to understand code. That's pretty impressive.

Or another way of putting it: It looks like naive Haskell outperforms naive C++, and naive Haskell is not that much slower than carefully-tuned C++.

template < typename Derived >
typename Derived::Scalar norm2( const MatrixBase <Derived >& v ) {
return v.dot(v);
}

Why is it a template function? Why does it return Derived::Scalar instead of double? Dear god, Eigen is magic.
YC Application
Hi all!

I am part of a start-up in Montreal that just submitted their YC application last week. I was just wondering if I could get some feedback on the actually application and how long does it take to hear back? Please feel free to email me at nkshiwdin[at]hotmail[dot]com

Thanks!
Has it ever occurred to the OP that maybe the Xbox 360 was such a huge success precisely because of the culture of the employees there?
They're not out of the woods yet in the EU: http://www.techspot.com/news/52067-microsoft-under-fire-in-e...
x86 has encodings for shifts by 1 that are two bytes, so there's no code size advantage.
Fine your satisfied with Europe, that doesn't mean you have to be an ass.
I learned Perl about 15 years ago and, while I love the language, am finding myself stuck in Perl from those days. Any resources I can go to to get myself up to speed with modern Perl practices?

I'd recommend chromatic's Modern Perl (http://www.onyxneon.com/books/modern_perl/index.html) and Curtis Poe's Beginning Perl (http://www.wrox.com/WileyCDA/WroxTitle/Beginning-Perl.produc...) as good places to start.
* Every cellular provider can also blacklist an IMEI

This is very country specific and requires the cooperation of all service providers. Once the phone leaves the country and registers on different network the block becomes ineffective. Thieves here know the phone will be blocked so they send it on to Russia, for example.

The title is a bit sensationalist. None of the famous animal ones were destroyed, just some of the straight line ones. It's ridiculous that a company felt that they could just quarry over part of a UNESCO world heritage site, but the title makes it seem like they're all gone when that isn't the case.
Everpix's support page lists the restrictions on file formats. RAWs are not supported. https://support.everpix.com/entries/20972951-What-kind-of-ph...

Supporting RAWs in a service like this is actually fairly difficult. Turning RAW files into something that can be displayed on the web or analyzed involves a lot of judgment calls by the software that does the RAW processing with regards to determining exposure settings, white balance, color profiles, noise reduction, etc. And processing them takes a lot more time than JPEGs.

At Picturelife (https://picturelife.com/learn, shameless plug, I work there) we support RAWs but the results aren't always perfect. Sometimes the image we produce appears too dark and sometimes the white balance is slightly off. Our solution has been to upload both the RAW and JPEG and show you in the interface which is which, with the intention of some day determining which file is edited/properly exposed one and displaying that while still allowing you to download the RAW. While we decided it's better to store all the originals including RAWs despite these difficulties, it's understandable that Everpix didn't.

Is the benchmarks game listed somewhere as a programming competition?

What a class-act.
Awesome, doubly glad I posted the link now!
It's almost certainly (c), and the rest of the ones that end with "and we're done". The first one is probably not (a) because it has a pronoun ("it's"), which would be a pain to program into a natural language process for this limited purpose.
Actually Intellij Idea has the same concept, here it is working in HTML: https://dl.dropbox.com/u/456905/idea.png

I think it would be great if they added it to JS, with their powerful syntax parsing it would be probably trivial to do.

Edit: probably works in their php, django and rails ide-s.
That seems to say that stock pickers and fund advisors have no skills, not very much about professional traders. whatsoever. I've read some stuff that said that the military has studied pit traders at NYMEX due to their skill in handling vast amounts of information and making split second decisions on it.
Nice! I assume this only works with gccgo (to create a shared library)?
Not surprised that James Altucher wrote the most shared post ever on TechCrunch, excellent writer.
Very useful tool, thanks for sharing it.
I'm not sure of any of my answers, but I guessed the computer generated proofs are: 1c, 2a, 3b, 4c, and 5c. These proofs seem to be the most uniform in language, especially the way they all end with "we are done". I was the least certain about 4c since this option doesn't seem in the established style of the computer (assuming my other guesses were correct).
That's how I read this too, those whimsical (childish?) games are still around now (don't ask me to list any ... i'm all growed up!).

My son's 17 so let me look through some of his old PS2 games... Kingdom Hearts, Ratchet & Clank, Jak & Daxter, Rayman, Tak - I think those all epitomize the type of game you are referencing, you just stopped playing that type of game because you grew out of them. Also, if you'd tried to play those games there would likely be plenty of peer pressure to keep you away, teenage boys are good at peer pressure like that.
Have you tried diagnosing with powertop?
Yes! My problem with the "CEOs make big decisions so they should get paid a lot" thing is that it encourages CEOs to set up companies where they make all the big decisions. And of course to draw all the attention to themselves. And to focus everybody on trying to figure out what the CEO wants, rather than what the customers want.

Contrast that with, say, 3M. The Post-it Note was a bottom-up invention. One guy came up with the adhesive. Another person figure out what to do with it. They've sold billions of dollars worth of the stuff. As far as I'm concerned, that makes the 3M CEOs much smarter than the hands-on ones. Instead of treating the company like a giant prosthesis, they created an ecology.
I guess playtime really is over.
Thanks for the vote of confidence. We think its a great tool too. There is much to wait for with additional insights that we are thinking about.

Would love to get feedback from the community about which other types of information and analysis they would like to see.
fuck that macbooks, they doesn't have home/end/pgdn/pgup/delete buttons. not for programmers at least.

Ebert having a rubber stamp of a thumbs up is cool.

More so to note he could use it as a thumbs down too.
Why are you using -O2 instead of -O3?

I wonder what percentage of those shares aren't completely generic, how many actually add anything?

As a relatively late adopter of "social", I was disappointed to find that the vast majority of sharing seems to be raw repeating. No opinion or contribution, just a contextless spray of links - bookmark broadcasting.

It would be interesting to see how the level of contribution when sharing varies by site/topic.
Giovane giornalista muore di freddo. “Che s’adda fa pe faticà”
He just did. There's a video and ad hiding everything about the site.

To me, the site is "something I'll never know because you have to watch a video to find out." A simple sentence wouldn't have been taxing on the creators.
I'm not saying I would. I prefer the trackpoint. But they should provide a decent trackpad or get rid of it altogether. I don't need both. This would make more space for palmrest, which is too small in x220.
I think (a) may be the undergrad student - still young and idealistic :)

Then (b) could be the PhD student who talked to enough people to be aware that you never know what others consider a ball.

Finally, (c) goes to computer because it's the longest one and it's full of Greek letters. I've known a PhD who believed only in proofs starting with "For arbitrary ε > 0, take δ = ...", but even he wasn't as boring as (c).
My experience generally with front-line staff making people follow policies is that they have no idea why the policy exists. I expect to have to go up one or two levels in the hierarchy before I find somebody who can talk sensibly. So I could understand him not bothering.

Also, he was clearly startled the first time, and then mad the second time. The blog post may have only occurred to him later.
This would be helpful for intergalactic domination. Kidding.
One of the biggest problems of switching to PyPy is to know which libraries are supported and what the best options are. For example, how should we connect to MySQL? Or use memcache? Or use Redis?

It would also be great with some stories of who runs PyPy in production and what their experience is (especially on large high-traffic sites/apps).
Just 3 things:

- Install powertop and enable all suggested tweaks

- Depending on your kernel you should downclock your i915 graphics card and force pcie_aspm

- Later kernels (>3.6?) have a power regression which leads to higher consumption in Sandy Intel architectures

Is it possible to get the most-shared data without scraping every TechCrunch post ever?

The data might be useful for a project I'm working on. :)
If that's the case, then it's time for small businesses to take their business elsewhere. The problem is, what other options are there?
Wow, I agree with every single point you've made.

I often see myself making comparisons too, but now I think they're more likely to result in bad feelings than in bringing me any kind of useful knowledge. So I just consider them useless and try to not make comparisons again.

Thanks for sharing. Good luck for you and me!

We've been analysing sharing patterns for a while. We tend to see that Twitter shares correlate too much with the amount of posts per day which may indicate its more bot driven.

FB Likes and +1 are much harder to fake and seems to correlate more with actual human traffic.

From our experience +1 tends to be factored into Google search results so there is direct value in having +1 on your site and having your visitors who like the content click on it (not to mention it gets circulated inside Google Plus itself).

We are working to add more sites as we go along and we would be happy to share some information about patterns across sites and topics.
This article was obviously not written by a creative person. I can't wait for their article on how to manage "nerds".

"Surround them by semi-boring people"

This might be true if your define "creative" as "primadonna who can't handle being challenged". I think there is a real synergistic effect when creative people collaborate.

"Pay them poorly."

Low pay will motivate them alright- to find another job.

I believe those studies found that if you started paying someone for something they were already doing for free (i.e. they didn't consider it work), you reduced their motivation. I don't think those studies can be construed to mean that paying someone below market will make them more motivated.
They do it to curb sharing of multi-day tickets, which is prohibited by their terms & conditions. It's a relatively quick way to check that the person who first used the ticket is the same person who returned with it, rather than someone they sold/rented it to. Selling or "renting" multi-day passes for some fraction of their days is a common way to make money in the areas around theme parks (and a common way for people to try to save money getting in). I don't think this is all that sinister.

I personally would rather have thumbprint scans than have to wait as each guest's photo ID is checked every time they enter.
I think it's not (a)

There's a line in that proof saying r=min{a,b}; normally I take that to mean r is the minimum of a and b (which makes the proof wrong, since not all metric spaces have obvious orderings on their elements. Spaces like the complex plane or the 2d plane, with an appropriate metric, for instance.

I suppose it could mean r is the point in {a,b} such that the ball B_a(x) or B_b(x) has the smallest radius - but that looks more like a human making a notational mistake, particularly given that both 1b) and 1c) use min(,) in a way that seems correct to me (since they're using min on the values of the metric, not the elements of the metric space.

AFAICT, either the prover made a mistake in logic or a mistake with notation - which I reckon makes him or her human.

Then again, it's been years and years since I thought about this stuff, and I was prone to making mistakes all the time when I did, so everything above might well be wrong. My neurons are getting all fuzzy these days.
Charles Barkley's "I am not a role model," which he wrote, represents to me the pinnacle of this liberating, honest, courageous, and genuine view.

Integrity in the face of judgment.
I'd agree with that. I actually prefer the keyboard on my backup laptop (An x121e Thinkpad), but yeah, love the Samsung's screen. Battery life isn't brilliant at 5-6 hours though. I miss my old Samsung x360 which used to give me closer to 8.

Ubuntu installed just fine on the S9. Everything seemed to work OOTB. But ended up reverting to Win7 for a contract I was working on while travelling.

The new 1080P Series 9 would be okay, but I'd be sorely tempted on a Chromebook Pixel.
Minor editorial nit: "Boostrap" (sic) is misspelled on the front page. Thanks for putting it up, though!
Booking.com (Amsterdam) runs on Perl.
This was about being gainfully employed and not risking unemployment, not about earning as much as possible.

You can make a well above average living as a developer in most places in the world, including London. It's ridiculous to claim that developer pay in London is "below average".
No, it's still an extern declaration. However the compiler is still allowed to "peek within" an extern function as long as it has the definition available.

You can see this by inspecting the disassembly yourself, you'll see that printf never actually calls divide, and yet the divide function is still defined within the executable output.
AFAIK, 'world heritage site' is just a marker indicating that "UNESCO considers it in the interest of the international community to preserve each site". It does not, by itself, carry any legal force.

If so, claiming a land owner can't do something to his property because it is part of such a site has no legal basis, but only a moral one.
For a while (not sure if they're still doing it), they were checking IDs for multi-day ticket holders at Disneyland in California (no fingerprint readers there). It slowed the lines down massively. I've been to both parks many times, and the fingerprint readers are immensely faster than checking IDs. For annual passes, they scan the pass and your picture comes up on the screen, but that's not as practical for a 3-day ticket.

I really, really hope I get to see this before I die. Space travel is something that has lost it's cultural significance (for some valid reasons, Columbia, Challenger etc) but to have something that the whole world can come together and be a part of would be incredible. Almost how the Eco movement started when images of the pale blue dot were circulated, would love to see something similar.

Sometimes there are "canonical forms" for these operations depending on what chip is being targeted, where the hardware can automatically break data dependencies and improve hardware-level parallelism, as long as the instruction is encoded in the right form.

I don't know that this is necessarily the reason here, but it's one possible explanation.
TechCrunch Founder Michael Arrington’s History of Abuse Allegations
Surely you realize that local governments have been doing this in all sorts of industries.

The give property tax abatements to WalMart or sales tax abatements for equipment deployed in a data center within their borders. This is nothing new.

And like someone else mentioned, TWC and Comcast have had de-facto monopolies for the past 20-30 years. Cable companies are bound by a franchise agreement with the city. One of the things they agree to in that agreement is that they have non-exclusive access to the market via the public right-of-way.

Also consider that one of the things cities will do is try to get ANYTHING that will bring jobs and industry/investment to their community. Growing the tax base is a prime directive of any city.
Right, and for a man who is self-deprecating it's a bit of a joke that he's become so successful.

There are so many people on Glipho who have left their blog because it's simply that much better. When I think blogging, it's not just the writing/reading, it's add this, modify that, update this, change that, add this colour, change this font, then on top of all of that go out and get your audience..When do you actually have the time to write on your blog when you have all of the above to do?

With Glipho, you just have to read and write.
Nice! It looks pretty simple, but it makes me wonder. Why bother interfacing your Python code with Go? Why not go straight to C for more performance?
can you give me a bit more info on "can't"? Did you try drag & drop or toolbar? what file type have you tried? We have a filter on content type in the editor, so only things read with content type image/* are inserted.

Perhaps this is too strict?

re "code" button, this would be trivial to implement but doesn't really belong in the widget. Just get the html out using jquery (it's your element) and show that instead of the element by passing through a formatter (or just jquery.text())
