Nope, that's the funny feature of transducers. Like lenses in Haskell, transducers compose in reversed order. (sequence (comp (map inc) (filter even?)) (range 10)) ;;=> (2 4 6 8 10…

But you'll need to document it very visibly that "Thou shalt call resource.close() whatever happened." C++ makes it possible for the library writer to take care of freeing the reso…

Nitpick: if (x You shouldn't use `new` either when throwing exceptions. Just: if (x

Bjarne's advice also applies to pointers wrapped as class members. There are just too many ways you can mess things up inside the class when dealing with raw pointers, examples inc…

> This is neat, but really disappointing that there is no feedback when… Here's how you can say the same in a more positive manner: > This is neat, and it would be even better if t…

I asked the same question in Twitter. Turns out James was actually augmenting (i.e. modifying) the array object `promises` to behave as a promise itself. I don't think this was a p…

Correct. The key difference is that the enable_if version can be overloaded with mutually exclusive requirements: template typename enable_if ::type foo(int (&bar)[N]) { // called …

And, by extending your second example, we can enforce the minimum array size with std::enable_if (C++11; boost::enable_if_c with C++03): template typename enable_if = 10), void>::t…

In my view it's exactly the opposite: (-> (california) bay-in city-on) ; "The Californian bay's city" vs. (city-on (bay-in (california))) ; "The city on the bay in California" The …

It might have been those UTF-8 ellipses: "…" Good to hear that you got it resolved, but are you sure that your character encoding settings are alright?

Oh, good to hear. It's how Posterous implements the embedding of Github Gists that probably is to blame here. I'm still thinking whether to switch my blog to another platform, mayb…

I think the lambdas are the more useful the more complicated the function is. Simple asynchronous tasks might be one such example. This one, however, still is a pretty common use c…

I don't think introducing more syntax to the language for a feature that ultimately is a library solution, is a sustainable way to go. But if you really need a compact notation for…

Interesting. Previously, the same company has been behind the 3D view of Nokia's map service http://maps.nokia.com/3D/ — more info e.g. here http://www.ubergizmo.com/2011/04/c3-tec…

Oh true, missed that. Finally pulled out the phone to realize this. And then the other option 16+20+20+20+16 / 32+40+40+40+32 already has too big a difference between the margins o…

It's not impossible to make it symmetric for both, though. With consistent spacings. E.g. 19+18+18+18+19 (iPhone 3GS) 38+36+36+36+38 (iPhone 4)

Anybody noticed how closely this, being from the programmer's point of view, is related to what Bret Victor [1] has been talking about from the UI perspective? Take http://worrydre…

Hmm, I think the months menu [1] that opens when you take the mouse to the bottom right corner should have months listed in the opposite order. It feels more logical to get the mos…

Also, the Updates link on the bottom of the home page is broken, points to /update.php, not /updates.php like it should. ;)

Seven years ago, maybe. But today's GPUs do it easily in their programmable pipeline (shaders). And where conditionals are costly, you can use tricks like: float temp = min(x, y); …

Yeah, the hotel room analogy breaks as soon as you realize that visiting some completely other hotel room will already overwrite that variable in the first one. But it was a fun st…
