A good point. Coming from the iOS side I missed this. I mentioned Xcode's garbage collection in passing, but pointing out that garbage collection is deprecated on OS X would've made a strong argument that ARC is the better way to do things.

If he was not misled by the false "on hover" representation of the link in his address bar, then its possible he means: 1. That Twitter uses a "short link" where Google uses some kind of (I trust) token-secured "open redirect" or 2. That Go

Redirects of all types are especially bad on mobile devices since they require a pointless new round trip, which anecdotally seems to double the amount of time it takes for a webpage to start loading. Since Facebook and many other services

Twitter wants to route links through their servers for at least two reasons: 1. Analytics and monitoring. (Google's results page uses the same technique.) 2. Disabling malicious and unwanted links.

This article is false. (Regardless of whether Quora will or will not grow.) Many of the arguments should have been tested against Facebook: elitism didn't slow the spread of Facebook. In fact, it was likely a main driver of growth in the wo

It's a curious line, and while when I read it I let it pass with conditional assent, I now think it's incorrect. Wall Street has poorer-than-usual ethics, and does commit crimes for profit, but in general it is wary of the legal system. Wal

"Tweet" is such a good replacement for "asynchronously broadcast" that it won't matter whether Twitter is still around. The meaning is clear from context. It would not surprise me if "tweet" became a reserved word in computer science resear

You cannot use legality as a defense for two reasons: 1. By renouncing your citizenship you put yourself in an extra-legal position. 2. The laws are perceived as underdeveloped. That's why the situation has attracted the attention of US sen

Yelp has a policy that bars reviews written on mobile devices. This is done to protect the quality of the reviews. You can't submit reviews from an iPhone either. The functionality doesn't exist.
