It's not like people who work at Facebook have to use PHP anyway - there are quite a few who work in "superior" languages, although most just use C++, Java, and Python. In my experience, the top-tier developers enjoy challenges and solving

PHP is used for a subset of development at Facebook. I'm not sure what the split is, but I would not be surprised if PHP is the primary language used by less than 60% of Software Engineers at Facebook. The rest code in C++, Java, Python,

I'm not on the HPHP team, but when discussing these results internally, they mentioned that HPHPc performance was improving during this time as well (as you would expect we would need to keep running the site efficiently), and the graph sho

(Work at Facebook, but not on this system, and know nothing about it.) It looks like the search matches on job title/position, and not content. That does seem a bit unexpected. In general, Facebook does not place much emphasis on programmi

Try another browser, and a malware/virus detector. Whatever is putting those ads in there could be doing a lot worse things.

Whoever took the screenshot has installed a browser plugin that is inserting those ads, or has some other form of malware doing so. It should be easy to test - just disable them all and they should disappear, and then turn them on one by o

What position was he recruiting for, and roughly when (let's say, which quarter and year)? How likely was he a new recruiter? I'm not sure I can express my skepticism about this enough - our security, safety, and site integrity teams are s

It could also be criminal groups that are trying to make their profiles appear less fake. I worked with the team that fight spam, scams, and the fake accounts that distribute them when I started at Facebook, and they expend a lot of time wr

It seems to me that "sell your personal data to advertisers" sows more confusion through its recognition than clarity. People who hear "sell your personal data to advertisers" without your background tend to believe it literally - money is

What makes you say that Facebook will "sell your personal data to advertisers"? Do you mean that advertisers pay to get information like your name, email address, street location, and other identifiable information about you, like in a huge

I'm sorry you are having a bad experience. It sounds like you have accepted some friend requests from some noisy/energetic people, and/or from people that you perhaps don't really care about. My experience is that unfriending people I don'

What about the comment history feature makes you uncomfortable?

by nbm 14y ago
This is a feature for groups, not for pages (the way companies generally interact with people who use Facebook). Groups are generally created by people for groups of people that already meet/know each other in person or to discuss a shared

As far as I know, at Facebook we don't give pre-emptively/usually give people a book to learn PHP. Those that don't know PHP (or are rusty) can generally get the syntax/keywords right in an hour, and then there's a longer time spent gettin

I have only a year and a bit of context since starting at Facebook, but here's my viewpoint. Facebook isn't trying to move away from PHP as quickly as possible. For years, there have been PHP components (primarily web front-end rendering,

My somewhat circuitous point is that the ability of a server to perform work is bound by something that runs out - CPU (no more CPU time available), disk I/O (can't handle more I/O requests to disk), network I/O (can't put or get any more p

by nbm 14y ago
Why can't the web server do other work with the CPU and other resources at the same time that it is waiting for those network operations to happen?
199.
by nbm 14y ago
I'd be interested to understand why you would classify web servers as generally I/O bound, rather than CPU (or memory) bound.

Of the 100 or so interviews I have done over the past year and a bit, only two or three have had cases where the interviewee did not need to admit they did not know. If my goal is to understand the breadth and depth of knowledge, then one

It is important to keep in mind that Facebook isn't just a single PHP code base, and thus one can't really make many assumptions about how well PHP is suited to solving certain problems because one doesn't necessarily know about which bits

The question is whether someone is saying that you can't use the PHP language/architecture to create a large and large-scale application like the Facebook front-end, or whether they mean the PHP runtime is unable to perform effectively at s

Facebook uses a combination of primarily PHP(1) (mostly front-end, rendering, some async jobs and scripts) and C++ (mostly back-end services, other bits of high-performance infrastructure, HipHop for PHP), with some Java (especially in the

If PHP is putting you off considering working at Facebook, then it may be useful to know that there are many developers who hardly ever touch PHP at Facebook. Most back-end services (ie, the systems that build your feed, or detect spam) are

Perhaps it is best for the database team to talk about that themselves - wouldn't want to put words in their mouths. They gave a Tech Talk in December last year, which you can see at http://livestre.am/1aeeW

People aren't forced to work nights and weekends during lockdown, although some teams may up their expectations for people to do that. I haven't been on a high-priority project for a lockdown, but I imagine it is possible that some go over
