I'll be spending the night trying to switch all the central datastructures of our service over to an arena allocator, since I'm pretty sure it'll be a nice win. And, with any luck, I'll sleep most of tomorrow.

These infamous lines are certain to get copied quite a bit more. In case you haven't seen them: private static void rangeCheck(int arrayLen, int fromIndex, int toIndex) { if (fromIndex > toIndex) throw new IllegalArg

Hi, fb engineer here. This is exactly what's going on. If you recall, there were several articles written a few months back pertaining to comment spam, and very low quality comments (ascii art or 'LOOOOOL!!!') from subscribers. This is part

UF's football program's 'budget' is a red herring. It's a profit center for the university. It doesn't "cost" 90M. It pays for itself, and a great bit more.

I can't believe in 2012 the #1 comment on a topic like this is comparing the valuation of a tech startup to an established brand in a completely different industry, and then appealing to the crowd's incredulity. Have we not yet learned how

As a 2004 graduate of UF (ECE, not CISE) this news worries me. Can anymore more familiar with the situation explain whether or not this more about consolidating ECE/CISE, or if this is just a simple gutting of the computer science at UF. Ma

What a great title. Completely impossible to not click on this and figure out what is going on.

Wow. I was expecting an interesting discussion. I was disappointed. Apparently the consensus on hacker news is that there exists a repository size N above which the benefits of splitting the repo _always_ outweigh the negatives. And, if tha

The tldr here is that iterating through large arrays simultaneously with identical alignment can be slower than non-simultaneous access because of cache associativity. It's basically hash collisions in the cache due to alignment. I've actua

You seem to be under a collection of interesting misapprehensions... 1. Google does warn in various ways when it detects possible badness. As it should. 2. We don't gate ALL links through such warnings. This can be verified by going to your

I work on the team that generated the warning that seems to be the crux of this post. I am pretty convinced that it is a bug. His central theme, though, is a bit misguided. I don't understand why 1) using opengraph, or 2) using a like butto

I am -so- glad you said it. I've been resisting the urge for weeks to point out the /r/politics-ization of hacker news for fear of being "that guy" (you know, the one complaining about the good ol' days). Just to be clear about what that me

Code changes are easy at facebook. Messing with domains/cookies/security/static-resources/etc is more than a code change.

There is another reason that is stated and restated, including elsewhere in this thread: it's not trivial to (actually) erase anything.

Let's keep in mind that they could already do this, relatively trivially, with far less technology, except you'd hand them your credit card first, instead of last.

How come no witches ever show up to our witchhunt? The vast majority of fb employees wouldn't know anything about this. They couldn't say anything except something w/o any knowledge and cause more problems.

Just being honest here, but both of your posts come off, to me, much more as you rationalizing a belief about what is true based on what you want to be true, and trying to "convince" us that most of this thing that "we" possibly value isn't

This is one of those posts that is made, and upvoted, based on what everyone wants to be true, instead of what is true. The simple, unassailable truth is that having strong contributions to open-source projects is a massive advantage in any

That is a weak defense of an equivocation fallacy. Claiming he didn't play along "hard enough" doesn't undermine -his- point that the original statement is an equivocation fallacy. While there is no platonic definition of the word, any two
