Introducing DeepText: Facebook’s text understanding engine
Text is a prevalent form of communication on Facebook. Understanding the various ways text is used on Facebook can help us improve people's experiences with our products, whether we're surfacing more of the content that people want to see or filtering out undesirable content like spam. With this goal in mind, we built DeepText, a deep learning-based text understanding engine that can understand wi
Introducing Proxygen, Facebook's C++ HTTP framework | Engineering Blog | Facebook Code | Facebook
Introducing Proxygen, Facebook’s C++ HTTP framework We are excited to announce the release of Proxygen, a collection of C++ HTTP libraries, including an easy-to-use HTTP server. In addition to HTTP/1.1, Proxygen (rhymes with "oxygen") supports SPDY/3 and SPDY/3.1. We are also iterating and developing support for HTTP/2. Proxygen is not designed to replace Apache or nginx — those projects focus on
This week Facebook will complete its roll-out of a new photo storage system designed to reduce the social network’s reliance on expensive proprietary solutions from NetApp and Akamai. The new large blob storage system, named Haystack, is a custom-built file system solution for the over 850 million photos uploaded to the site each month (500 GB per day!). Jason Sobel, a former NetApp engineer, led
Introduction to Facebook's Flux architectureFebruary 21, 2015 The versions of Flux and React in this article are quite old - some of this may not work If you’re like me and you wanted to go further with React, you more than likely would’ve checked out Flux, had a glance, closed the tab and then reassessed your life as a Javascript developer. If you’re not familiar with React, please checkout my ge

Facebook’s GraphQL gets its own open-source foundation – TechCrunch
GraphQL, the Facebook-incubated data query language, is moving into its own open-source foundation. Like so many other similar open-source foundations, the aptly named GraphQL Foundation will be hosted by the Linux Foundation. Facebook announced GraphQL back in 2012 and open sourced it in 2015. Today, it’s being used by companies that range from Airbnb to Audi, GitHub, Netflix, Shopify, Twitter an
On distributed systems broadly defined and other curiosities. The opinions on this site are my own. I had summarized/discussed a couple papers (Haystack, Memcache caching) about Facebook's architecture before. Facebook uses simple architecture that gets things done. Papers from Facebook are refreshingly simple, and I like reading these papers. Two more Facebook papers appeared recently, and I brie

以下の文章は、Chris Dixon による Facebook’s business model の日本語訳を著者の許諾を得て公開するものである。 スタートアップは通常、一つの主要製品なりビジネスイノベーションのおかげで成功する。Google が普通でなかったのは、二つの大きなイノベーションで成功した点にある。それはコアとなる検索製品と、キーワード広告のビジネスモデルだ。さかのぼること2000年、Google がすごく人気だったものの、まったく収入を生み出してなかった頃、彼らのビジネスモデルは先が見えないのというのが世間一般の見解だった。その後 Overture がキーワード広告を発明し、Google も同じモデルを採用した。これが激しくもうかることが分かったし、しかも珍しいことに広告主とユーザの双方により良い体験を与えた。 Facebook は旧来のインターネットのビジネスモデルに依存し

Running CakePHP using the Facebook's HipHop compiler | The Bakery, Everything CakePHP
I always had the curiosity of trying to compile CakePHP to C++ code, but never had the time. This year I decided to give it a go... Facebook surprised the PHP community in early 2010 when announced they managed to write a compiler for PHP to produce C++ (http://developers.facebook.com/blog/post/358) code. Being PHP the most popular language for web applications, it faces a lot of competition from

If you're willing to go and use immutable-js for your data interaction, it can be quite easy to use it. Should you use it? Pros: Immutable.is() makes checks for changes to props trivial Easy to just compare references instead Easily converted into vanilla JS objects Don't have to use React.addons.update and its ugly syntax Merging objects is trivial Simple, easy to understand API Immutable Ability

Two billion photos are shared daily on Facebook services. Many of these photos are important memories for the people on Facebook and it's our challenge to ensure we can preserve those memories as long as people want us to in a way that's as sustainable and efficient as possible. As the number of photos continued to grow each month, we saw an opportunity to achieve significant efficiencies in how w
Mark Zuckerburg just announced that Facebook has agreed to buy mega-popular photo sharing service Instagram for $1 billion. Facebook's been on a buying spree of late, and has been beefing up its own already-ubiquitous photo sharing service lately as well. But it looks like it just landed a whale.
Marco ArmentがFacebookのOpen Compute Projectを斬る（Facebook’s Open Compute Project 日本語訳）
以下の文章は、Marco Arment による Facebook’s Open Compute Project の日本語訳である。 Facebook が Open Compute Project をリリースしたばかりだけど、これは最も大きなウェブサイトやウェブホスティング企業といった何百、何千のサーバが必要な場合に最適化されたデータセンターとサーバデザインを公開するものだ。 ハードウェアは Google が2009年に公開したものにやや似ているが、バッテリーバックアップに対するアプローチが異なるし、公式な設計文書も完全に公開されるので、理論的には他の誰もが Facebook の設計をコピーできるし、それを改善できる可能性もある。 冷静な業界ウォッチャーから見れば、Facebook の設計に特に革命的なところは皆無である（優れた PSU 効率を除けば）。それよりずっと興味深い疑問は、なぜ彼ら
Improving Facebook’s performance on Android with FlatBuffers
On Facebook, people can keep up with their family and friends through reading status updates and viewing photos. In our backend, we store all the data that makes up the social graph of these connections. On mobile clients, we can’t download the entire graph, so we download a node and some of its connections as a local tree structure. The image below illustrates how this works for a story with pict
