The mythical expert programmer... Everyone has a cognitive limit on what they can keep track of/in working memory. Once your codebase exceeds that limit (in # of files, lines of codes, types, interfaces, etc.) you lose productivity. 10

Not taking surge pricing into account probably plays a large role in explaining this article's findings. Another thing to note in his section with self driving cars: the pool of cars would be fixed in that case, but the amount of uber

Yes, the email system could be better. But for something that was designed decades ago it works surprisingly well. Should somebody try to do some smart parsing of failure notifications to make them more readable? Sure, I don't see why not

(Disclosure: FB employee, but nowhere near the photos/locations teams, just personal experience) In all likelihood, there's no magic. Its just comparing 'dumb' manual album labels with places pages and trying to match them up. I've had simi

Other fb employee here. One of the other annoyances we had (I think its addressed in the note?) is that until now the interpreter (on our dev machines) and the compiler (hphpc in production) occasionally differ in small, occasionally painfu

While I agree with you, I think the article was talking about the nontechnical consumers, the ones who don't understand what mhz and gigabytes mean, they just want a computer that does what they want it to do (yes, I'm being intentionally v

Except the differences aren't subtle at all. In laptops, choosing between brands can mean a major change in build quality/durability. The difference between 4gb and 8gb of ram? Huge difference (even if you aren't running memory hog progra

So, I'm going to make a statement that I think is important for anyone reading anything on the internet. WHAT IS THE PROOF! (also known as 'consider the author', 'read the article', etc) Now I can't say with certainty that any of these cla

afaik, facebook does not use flash cookies. In the initial blog post that caused the cookie uproar, I thought he mentioned that? Otherwise maybe it was somewhere else I read it.

Source? That doesnt sound like an unreasonable number, but I'm dubious of articles like this (site I've never been to before, obvious bias, lack of source).

That may be true, but even if it is, it isn't sharing this activity with your friends, that would be facebook doing exactly what google does with their analytics platform/js. I don't get the freakout people have over fb potentially tracking

Couldn't agree more. Its been the use of XHP and looking at the ... contraption HPHP is that started me thinking about this in the first place.

I had a friend mention this to me before I wrote this, and it does seem pretty neat. That said, I think it's big shortcoming to me (havent spent much time with it, spent ~10 minutes going through some of the demos) is that its a functional

Perhaps? It's unclear that a JIT with type inference will give you better performance than compiling (especially if you were to do profile guided optimization) (sidethought: not sure if llvm has support for PGO). Also, if most of your types

Right on. I'm not sure I'd go so far as wanting the language to be as strict/typesafe as those (also calling Haskell an ML derivative is kind of funny, but I know what you mean)

So, like I said in the post (but perhaps didn't make clear enough) is that there are plenty of options for when scaling isn't too much of an issue. But you take a look at Twitter (Ruby/rails and now scala, I think? which kinda goes towards

I wouldn't deny that fragmentation is an issue, although from my (limited) personal experience the biggest issue has been designing for all the different screen sizes/resolutions and still having your app look okay. And yes, any antipiracy

This article is citing a lot of out of date information (unsurprising, since its 9 months old). I suppose that the article should be taken with a grain of salt given the source anyway, but just a heads up on a few: a)the Wired article that
