Any chance of getting some transparency of what automated or manual processes have affected a particular story (ie, on the story comment page itself), possibly delayed by some period to prevent bad actors from realising their voting rings o

That is a bit simplistic and is missing a bunch of things. First the numerous C++ and Java backend services that do most of the heavy lifting like producing the feed, doing searches (of various types, both from what people type in, and inte

I don't recall Beast ever having anything but a Page - in fact, I remember that Zuck mentioning in a Q&A that he was using Beast to get a better feeling about what it's like to run a Page.

It's hard to answer this easily in a holistic fashion without getting really abstract. Is there a particular part you're wondering about?

That's not totally accurate - sometimes you're exchanging more than just the item in question, for example, putting yourself in danger. In other words, if you can sell an item for $100k if you follow a set of laws (a government&#x

The existing Facebook deployment system supports running deployments within an LXC (and setting up cgroups, &c.) and was written well before docker was available. Some background: * http://www.slideshare.net/dotCloud&#x2

This isn't my area, so I don't know what we've previously disclosed or what agreements we might have in place with vendors about, say, not mentioning them, so I don't feel comfortable disclosing that. If it was anything

I work in a somewhat related team (Traffic/CDN) at Facebook, and I'm very excited about what this is going to allow us to do in future. Current switches just don't support the deployment, monitoring, and configuration power w

The systems described here isn't directly involved with any PHP code. Like all Facebook services, they are communicated with over the Thrift RPC system, and may have PHP (or any other language) clients, and may talk to other services u

Is there a reason to ask people for their names? To just try it out, I first just ignored it and pressed "Start". When that failed, I typed "a" as my name and tried again, which also failed.

The Reddit front-end is a relatively simple application. It has a page with a list of stories. It has a page with one story and a bunch of comments. It has a page to add comments. It has an endpoint to vote up or down stories, and to vo

As much as I prefer not to engage trolls... Which language would have been a good technical decision in 2002-2003? It needs to be fast enough in terms of iteration. It needs to not require more resources than PHP. It must be easy to onbo

Facebook hasn't used plain old Apache/PHP in production for several years (HipHop for PHP was announced in Feb 2010), so it is hard to compare. HHVM is its own web server (although it supports FastCGI for easier use with existing

Facebook already has several decoupled services written in other languages. The PHP codebase is mostly the front-end code which, beyond some database work, dispatches heavy lifting to back-end services written in C++, Java, and other langu

Pretty much only the front-end code is written in PHP (or Hack, I guess). Services (things like the feed, the typeahead, graph search, messages, &c.) are written in C++ and other languages - ie, the things it is sensible to write them i

I believe Python might have worked. It's grown well as a web development language since then by itself. It may have forced several rewrites before WSGI came about. It is a relatively easy language to learn, to hire for, and has few

I'm not sure if Wyatt, Qi, et al. looked at pre-caching at all. I've not looked at the numbers yet, but it's on my list of things to look into once the next few months of more obvious wins are worked through.

Yes, mostly due to new content. You have to miss on the first request for the new content, and each of the 350 million or so photos a day will contribute a miss. Also, this only ran over a particular time period, so one-off requests for o
