より簡単に表現していただけるよう、ツイートの文字数を増やします
1つのツイートに考えをまとめることがなかなかのチャレンジになることがあります。社員である私たちも体験しています。 でも、世界中の方々が同じように感じているわけでもなさそうです。例えば私（Aliza）が英語でツイートをする際、すぐに140文字の上限に達してしまうので、制限文字数内にまとまるようにツイートを編集しなくてはなりません。場合によっては伝えたい思いや感情を表す単語を削除したり、ツイートすることを諦めたりしてしまいます。同僚のIkuが日本語でツイートするときには、このようなことは起こらないようです。伝えたい思いを書いてもまだ文字数に余裕があります。これは日本語、中国語、韓国語では英語やスペイン度、ポルトガル語、フランス語などの他の言語に比べ、倍ちかい情報量を伝えることができるためです。 世界中の方々にご自分を簡単に表現していただけるよう、日本語、中国語、韓国語以外の言語では1ツイートの
Manhattan, our real-time, multi-tenant distributed database for Twitter scale
Manhattan, our real-time, multi-tenant distributed database for Twitter scale As Twitter has grown into a global platform for public self-expression and conversation, our storage requirements have grown too. Over the last few years, we found ourselves in need of a storage system that could serve millions of queries per second, with extremely low latency in a real-time environment. Availability and
Libcrunch and CRUSH Maps
When we introduced our in-house photo storage system Blobstore to the world, we discussed a mapping framework called libcrunch for Blobstore that maps virtual buckets to storage nodes. The libcrunch implementation was heavily inspired by the seminal paper on the CRUSH algorithm. Today, we are open-sourcing libcrunch on GitHub under the Apache Public License 2.0 to share some of our code with the g
The Twitter Platform
Enduring Value When we discuss the future of Twitter, we focus on the mechanisms through which we can build a platform of enduring value. The three mechanisms most important to building such a platform are architecting for extensibility, providing a robust API to the platform’s functionality, and ensuring the long-term health and value of the user experience. The purpose of this post is to explain
Enabling A Rush of Innovation
Even before Twitter was officially a company, we opened our technology in ways that invited developers to extend the service. Before long, Twitter became a platform and an ecosystem of innovation began to grow. Recently we’ve announced partnerships with Yahoo!, Google, and Microsoft. These Web leaders gained access beyond our free offerings—we licensed them the full feed of all public tweets. This
Project Retweet: Phase One
Some of Twitter’s best features are emergent—people inventing simple but creative ways to share, discover, and communicate. One such convention is retweeting. When you want to call more attention to a particular tweet, you copy/paste it as your own, reference the original author with an @mention, and finally, indicate that it’s a retweet. The process works although it’s a bit cumbersome and not ev
Building on Open Source
Kestral photo by mugley When we plan new engineering projects at Twitter, we measure our requirements against the capabilities of open source offerings, and prefer to use open source whenever it makes sense. By this approach, much of Twitter is now built on open source software. In some cases, our requirements—in particular, the scalability requirements of our service—lead us to develop projects f
Changes Afoot
We’re getting ready to launch a refresh of parts of the Twitter.com interface. This release does not include any new features (well, one). It’s mostly cosmetic changes. This post describes what we’re doing and why. Moving the tabs The most significant change you’ll notice on the logged-in homepage (/home) is that we’ve moved the tabs that were on the top of the timeline to the right sidebar. We di
Finding A Perfect Match
Last month, Twitter had a very special date in New York City. We met with another startup, had lunch at the famous Shake Shack, and spent some quality time together in Union Square. The meeting with this other startup was largely a formality—we had already fallen in love with both the technology and the team. Keeping up with interesting news and people you care about is one dimension of Twitter, b
Too much Jabber!
We found an errant API project eating way too much of our Jabber (a flavor of instant messenger) resources. This activity (which we’ve corrected) had an affect of overloading our main database, resulting in the error pages and slowness most people are now encountering. We’re bringing services back online now. Some will be slower than others for a while, and we’ll be watching IM and IM-based API cl
Twitter Chooses NTT America Enterprise Hosting Services
We have a stated goal to make Twitter a reliable global communication utility. While we continue to grow around the world, reliability is our most important measurement of success. In order to become a utility that people will use every day for more reasons than we could ever imagine, we need to earn trust. We’re proud to announce our strategic alliance with a company known for reliability. A subd
