alias please=sudoKeeping a site like Tumblr alive and snappy for you to post at a moment’s notice, all day and night, is no small feat. Pesky crabs sneak into our data centers and cut cables all the time… If you want to help our small but excellent systems team, want to work from anywhere, and are deep into nginx, mysql, kubernetes, and caching, join us in this adventure. Or, if you have a friend
At Tumblr, we’re always looking for new ways to improve the performance of the site. This means things like adding caching to heavily used codepaths, testing out new CDN configurations, or upgrading underlying software. Recently, in a cross-team effort, we upgraded our full web server fleet from PHP 5 to PHP 7. The whole upgrade was a fun project with some very cool results, so we wanted to share
One of the biggest challenges we continue to face at Tumblr is how to properly organize and scale our infrastructure as the platform continues to grow. One strategy that has been very promising is the implementation of microservices. These are small, specialized applications designed to efficiently encapsulate a single feature or component. Instead of having one monolithic application that contain
Tumblr is one of the largest users of MySQL on the web. At present, our data set consists of over 60 billion relational rows, adding up to 21 terabytes of unique relational data. Managing over 200 dedicated database servers can be a bit of a handful, so naturally we engineered some creative solutions to help automate our common processes. Today, we’re happy to announce the open source release of J
Once again it was Hack Week (more than just a day!) at Tumblr! This is getting repetitive in the best way. A couple of times per year we slow down our normal work and spend a week working on scratching a personal itch or features we want as user and see how far we can get with our hacks. One thing from the last Hack Week in September made it all the way to a new experiment out to some testers: Tum
Soon after I started at Tumblr all the way back in May, I was tasked with reworking our aging notifications system. A notification is the item that shows up in your dashboard, interleaved with posts, that tells you that another Tumblr blog reblogged or liked one of your posts or started following your blog. Until recently, notifications had been served up by a fairly standard MySQL layer with some
AKA why are some of my GIFs being turned into videos? OverviewWe’re experimenting with serving GIFs as MP4 videos instead of GIFV (which typically serves animated WebP) on the web to a small subset of folks on Tumblr, not everyone. This does not affect anyone using the mobile apps.The performance improvements from using MP4s in this way are huge, and will make Tumblr load animated images faster an
Welcome to the Tumblr API, v2! Want to know what’s changed and why? Read on. Just want to dive in? Head on over to the API documentation, sign up for a key, and get hacking! New Features Features on Tumblr evolve rapidly. With the API, we have not attempted to provide complete feature parity with the website. Instead, we’ve focused on those features which have become widely adopted and thus core t
