文章里面我最喜欢的一句话是:"I've had 8 different desks in the last 4 years, 5 buildings, 4 managers, 2 cells phones and probably the most import thing, I've gotten to work with the most amazing people on some of the hardest problems around.".

As my 4 year anniversary has arrived, I'm in awe(敬畏) of where we've come in such a short time. 4 years ago we just crossed 60 million active users and we were in a constant fight to improve performance for the users. We were constantly working to keep our memcache servers from falling over, cpu on the web tier was an even more precious resource, and we were overall scrambling(争夺) to buy new servers and data center space. We had a saying back then, every time we hire a new engineer, the site got slower. It was so bad, that most of the time we had no idea what was causing regressions(退化), other than home.php was slower by 100ms, memcache(缓存) gets increase by N, db queries were up, etc etc. We had a very coarse(粗糙的) view of what changed to slow everything down.
2008 we finally got phprof and were able to get a detailed view of our performance regressions, Tony, Marc K and I spent considerable amounts of time trying to scale the cache tier(层) to handle the ever growing demands on it. I moved offices 3 times in 2008 and I was lucky enough to help the first wave of n00bs go through bootcamp(训练基地). I don’t think people fully understand how hard it was to start as a n00b in 2007. When I started, I was met by my mentor(指导者), handed a laptop and that was it. I had no idea what to do, where to look and it was quite intimidating(吓人的) to be the new person having no idea who to ask for help. Our on-boarding of new engineers is so amazing, I'm extremely proud of what we've done to make it easier to bring in our wonderful new talent.
I could go on and on about the various things that happened over the last 4 years and I'm constantly amazed at how quickly we've adapted and executed to create this great company, while still maintaining our amazing culture. It's been the greatest ride of my life so far and I'm looking forward to the next challenges that await me. I honestly can not believe how much the company has changed and how much I've gotten to be a part of that. I've had 8 different desks in the last 4 years, 5 buildings, 4 managers, 2 cells phones and probably the most import thing, I've gotten to work with the most amazing people on some of the hardest problems around.
As I embark on(从事) the next phase of my career, I hope many of you realize what a special place Facebook is and how lucky we are to work at a place that has so much impact on people lives and the world. We've changed governments, reunited families and countless other stories and we should be extremely proud of that. I never imagined we'd be in this position in the world, but I'm very proud of us and I can't wait to see what's next.
So after all this reflection(沉思), I'll see you all in MPK next week, in our awesome new digs(摸索), and for those of you who thought this was a farewell(告别会) letter, sorry, but you're freaking(变得非常) crazy for thinking I'd leave and entertain those thoughts just because I've been here for 4 years. Do you know how many people have come up to me in the last few weeks asking if I was going to stick around(逗留) because they knew I was coming up on 4 years here? I'm actually honored that my co-workers are worried about me leaving, but seriously people, I bleed blue(忧郁的), and I even turn blue sometimes after swimming in the bay(海湾), but I'm not going anywhere, because I believe it's hip(非常时尚的) to stay, not leave.
Here's to the next 4 years!
