The other alternatives specifically for logging are Scribe (which we use here at Facebook) and Apache Flume. As I understand the use case for this software, it would be talking UDP to a local syslog server, not over the network. At Facebook

First, don't do anything that will likely hurt your own situation. If you have a reasonable belief the HR team or others would share your identity along with the disclosure, and you don't feel confident you can quickly find a new

I'm involved in several (20+?) conversations a year where Big-O is used. It's mostly used as a very efficient shorthand for explaining the source of a performance or memory problem (instead of an algorithm being "slow"

I'm surprised nobody has brought up that this was originally called GOAWAY in the spec, and that it was only renamed from GOAWAY to GTFO five days ago. It's not like it was always named GTFO or that people are remotely attached t

Since I decided to visit the site based on your comment, I figure you might want to look at optimizing the image on the front page - it's a ~670k PNG that took 12 seconds to download...

It may be hard to find someone who understands your situation very well, but I would recommend trying to find the small nuggets of insight or underlying thought you can find from those you speak to about it. Anecdotally, I consider myself l

Code style is enforced (but overridable) by the code review system - both automated tools that provide feedback ("lint") on the code (things like "Don't use funcx() - it sucks <link here> - rather use funcy()"

I'm not sure about the particulars of this one, but a lockdown is generally a period where you are encouraged to prune away unnecessary and/or lower-priority requests for your time. There generally aren't a lot of status meet

http://en.wikipedia.org/wiki/Coloured is fairly accurate. "Coloured" refers to (and is used self-descriptively by) a subset of people of mixed race of generally one or more of usually British and Dutch ancest

As a complement to dr's offer above, if you want to talk to someone who has been at FB for a while and worked with a bunch of infrastructure (traffic, core systems, &c.) and product (graph search, site integrity, &c.) teams, hi

I'm a recent user of Presto and Hive at Facebook after being here coming up to three years. I've been using them primarily to understand ways in which we might be sending people's traffic to non-optimal locations, or non-opt

In some ways that might be an advantage. More people are going through the growing pains associated with tens of millions of people using their site and request-per-second and data size problems, and making trade-offs for that providing se

This is something I've often struggled with before I joined Facebook, and it's something I occasionally grapple with there too. Like you, I felt I was usually correct, but had come to the realisation that not only was I occasionally wrong

It is quite a bit easier than you make it sound. The photo will have been posted with a audience selected - something like "Only Me", "Friends", "Public". If people were tagged in the photo and it is set to "Friends", then those tagged an

I suspect he may be conflating recruiters and interviewers to some degree, if one assumes he is being honest. Recruiters know that an employee referral is more likely to yield a hire, so it makes sense they might use that to prioritise thos

The MBP retina has a higher resolution, and also has two Thunderbolt ports (on the same side as the power, which is nice if you have a Thunderbolt Display with the combined power and Thunderbolt cable). Also HDMI output and SD card slot on

This "encode problems into names" approach is something I first ran into at Facebook. When a particular function or class is found to be a problem (or when it is known to be a problem in advance), it is (re)named something like "foo_POTENTI

The last Hacker Fair was pretty awesome as a potential recruiter - a bunch of bright people showing off stuff they're proud of (some of them slightly jetlagged, which can be amusing), really engaged in an informal environment where power is

I have no idea offhand if that's the full list - it's the list I come up with when I think about the question. But that's the thing - it's a bad question. It should be asked as "what does this do?" or "how do you do this?", like: "What doe

Self-selection can potentially be powerful for a startup (although maybe less so recently), meaning that it may be possible to spend significantly more time considering each candidate. Skipping initial recruiter calls for at least a subset

Yeah, I really enjoy working with our recruiting team - they display the same interest in being better at what they do and willingness to put in the effort necessary to improve as the engineers I work with, and that earns them my respect. T

I've been hired on bravado, reputation, pointless trivia contests, and other ways of interviewing, and it scares me that companies are willing to take on a risk without verifying skills in some way. I've also been on the receiving side of d

I am not personally aware of anything like that happening frequently, although I do know that Facebook has previously invested (amongst other things) in evaluating the use of certain types of questions before, with some interesting results.

That's pretty awesome opportunity and investment. I wonder how they deal with understanding/measuring performance with these short engagements. (Facebook has a "hackamonth" program which people who have been at the company for 18 months are

I'm a "well-calibrated interviewer" at Facebook for my role (Production Engineer), and some things from the post sound fairly similar. I consistently do two-ish phone interviews or on-site interviews a week. I'd say 2 hours is a little on
