We posted an update about this back in April, and now as of July 1st, it’s really, really here, for everyone: the old dashboard has been replaced with our brand new web experience on desktop. This has been a very long time in the making, and the primary reason behind it is to make the desktop web experience of Tumblr easier to maintain and build on top of.

We’re continuing to improve the experience of using Tumblr on the web with some new features, some of which were formerly a part of XKit and other third party extensions:

• Color Palettes are now available to change the whole look of the site, just use the “Change Palette” option by clicking on the silhouette icon at the top right.
• Viewing tags used in reblogs is now available in the notes view on every post.
  
• You can now filter posts by their text content, not just by tags.
  
• Timestamps are available by hovering over the “fold” at the top right of any post, or now also available by clicking on the meatballs menu at the top right of any post. There are a lot of new options in there, too!
  
• The dashboard now soft refreshes by default, so you don’t have to press that browser button to see the latest content.
  
• Audio in audio posts can now “pop out” so you can see it while you scroll your dashboard.
  
• There’s now a CSS map, API access helper, and more, available to third party extension developers. Keep an eye on this repository!
  

One piece of feedback we heard a lot was allowing pagination by changing the URL of the dashboard, and that’s something we plan to support. Thank you again for all of the insightful feedback about the new web experience, keep it coming!

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: Tumblr Patio!

Here are some of the projects that got built for our most recent Hack Week in January. Some of these things you may also end up seeing on the site…

Spoiler text, spoiler blocks, and centered text!

This one is so obvious and amazing, it’s wild we don’t already have it. For Hack Week, Katie added the ability to select text in a paragraph to be hidden behind a wall of black that can be revealed with a tap. This can be super useful to hide spoilers. And even better: whole spoiler blocks. And while we’re here, the ability to center text!

A plethora of new default blog avatars

We haven’t updated our default avatars in several years. (Some of you may remember this one from 10+ years ago.) They’re feeling a bit stale to us, so why not update them? And while we’re at it… make a ton more variations! Paul from the Tumblr Design team came up with a suite of new default avatars, using our latest Tumblr color palette. Here’s a look at some of them, but there are actually many dozens more using different colors:

Notifications and emails about engagement on your posts

This one is for the folks on Tumblr who love numbers and their Activity page. Daniel, @jesseatblr​, and the Feeds & Machine Learning team worked on some new notifications and emails we could send out to people about how their posts have been doing lately on the platform, such as how many views they’ve gotten, and by how many people. We already have this available (and more) when you Blaze a post, but why not open it up to more people? It’s really useful to the folks who use Tumblr to help build an audience for their work!

A new way of navigating the web: the Command Palette

Some apps we use a lot have a “command palette” accessible via a keyboard shortcut for quick keyboard-driven access to different parts of the platform. For example, Slack and Discord have Command + K to access their quick switchers to hop around conversations. What if Tumblr had one? Kelly and Paul built one! Press Command/Control + K on Tumblr and you can use your keyboard to jump to your blog, Activity, your recent conversations, search, dozens of places!

As always, stay tuned to the @changes​ blog to see if any of these hacks make it on Tumblr for real!

Keeping 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 or a colleague who’s good with servers, send them our way.

Once again it was Hack Week (more than just a day!) at Tumblr! 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 Day in March made it all the way to production: redesigning how direct messaging looks on Tumblr! Pretty cool!

Here are some of the projects that got made for this most recent Hack Week in September. Some of these things you may also end up seeing on the site…

Tumblr Patio

Maybe this will look familiar to you, but we love this idea of being able to organize Tumblr feeds into many “columns” side-by-side, creating a very dense but lively view of Tumblr. Lenny, Kelly, and Paul hacked this together, and we’re pretty excited to see where it’ll go. Each column can be a different feed on Tumblr, like For You, Following, your Activity, a specific blog, a search, Trending, even a Collection, so many possibilities!

Tumblr Booths

Meanwhile, a separate team of @autoplanes, Katie, @lex, Shaun, and Eve dug into the idea of selling digital and physical goods through blogs on Tumblr, leveraging our sibling platform WooCommerce! Blogs could put whatever they’d like for sale here, and have a dedicated space for it. We know there are so many amazing artists and artisans here who could use this to more easily sell their creations on Tumblr!

Avatar Frames/Hats

This one is a golden oldie, it keeps coming back hack day after hack day, and each time it gets even better. Santi and Maxime hacked together some example avatar “frames” and “hats” that folks on Tumblr could purchase for their blog. Maybe eventually people could create these and sell them or gift them to each other!

StreamBuilder: our open-source framework for powering your dashboard.

Today, we’re abnormally jazzed to announce that we’re open-sourcing the custom framework we built to power your dashboard on Tumblr. We call it StreamBuilder, and we’ve been using it for many years.

First things first. What is open-sourcing? Open sourcing is a decentralized software development model that encourages open collaboration. In more accessible language, it is any program whose source code is made available for use or modification as users or other developers see fit.

What, then, is StreamBuilder? Well, every time you hit your Following feed, or For You, or search results, a blog’s posts, a list of tagged posts, or even check out blog recommendations, you’re using this framework under the hood. If you want to dive into the code, check it out here on GitHub!

StreamBuilder has a lot going on. The primary architecture centers around “streams” of content: whether posts from a blog, a list of blogs you’re following, posts using a specific tag, or posts relating to a search. These are separate kinds of streams, which can be mixed together, filtered based on certain criteria, ranked for relevancy or engagement likelihood, and more.

On your Tumblr dashboard today you can see how there are posts from blogs you follow, mixed with posts from tags you follow, mixed with blog recommendations. Each of those is a separate stream, with its own logic, but sharing this same framework. We inject those recommendations at certain intervals, filter posts based on who you’re blocking, and rank the posts for relevancy if you have “Best stuff first” enabled. Those are all examples of the functionality StreamBuilder affords for us.

So, what’s included in the box?

• The full framework library of code that we use today, on Tumblr, to power almost every feed of content you see on the platform.
• A YAML syntax for composing streams of content, and how to filter, inject, and rank them.
• Abstractions for programmatically composing, filtering, ranking, injecting, and debugging streams.
• Abstractions for composing streams together—such as with carousels, for streams-within-streams.
• An abstraction for cursor-based pagination for complex stream templates.
• Unit tests covering the public interface for the library and most of the underlying code.

What’s still to come

• Documentation. We have a lot to migrate from our own internal tools and put in here!
• More example stream templates and example implementations of different common streams.

If you have questions, please check out the code and file an issue there.

Well well well, it was Hack Day once again at Tumblr. A few times per year we slow down our normal work and spend a day (or sometimes a whole week) working on whatever we want and see how far we can get with our hacks. Here are some of the projects that got made for our most recent Hack Day earlier this month. Some of these things you may also end up seeing on the site…

Wesley worked on adding the ability to translate the text content of posts using LibreTranslate, which works really well! We know this is a big pain point for folks who use Tumblr around the world, so we’re excited to keep experimenting with this.

Omar built a Feature Wishlist for the Android app, which has different lists for community-driven and staff-driven feature ideas, with the ability to upvote which ones you’d like the most! Really cool, we’re trying to think of ways like this to expand what we can do to collaborate with the community, like we already do with the @wip and @changes blogs.

One thing that’s been bugging @blowery forever is trying to figure out who exactly added the tags when you’re viewing a reblog of a post. It can be hard to tell whether the person reblogging it added the tags, or if they’re meant to come from the reblogged post. To help distinguish this, they hacked together putting the reblogger’s avatar next to the tags they added at the bottom of their reblog!

@straku hacked together a more modern look for our 1:1 messaging on Tumblr, bringing the message bubbles into a left-and-right back-and-forth format, and using some better colors. Looks a lot snazzier!

Ah yes, it was Hack Day once again at Tumblr. A few times per year we slow down our normal work and spend a day (or sometimes a whole week) working on whatever we want and see how far we can get with our hacks. The main star of the last Hack Week was… pretty much all of them!

Here are some of the projects that got made for our most recent Hack Day earlier this month. Some of these things you may also end up seeing on the site…

@yi5h worked on a huge suite of “rewards” that folks on Tumblr could unlock by doing various things on the platform, such as reblogging, creating content, even just logging in! Maybe you could earn badges this way to put on your blog…

@straku hacked together a new way of viewing reblog trails. We commonly get feedback that reblog trails are difficult to understand, so styling them differently to make the information clearer is fun to try out!

Meanwhile, Evgeniy built a beautifully simple “Back to Top” button for the Android app, which does exactly what it sounds like: brings you back to the top of whatever feed you’re currently viewing. No more scrolling, scrolling, scrolling — just one tap!

It was Hack Week (more than just a day!) once again at Tumblr! A couple of times per year we slow down our normal work and spend a week working on whatever we want and see how far we can get with our hacks. The main star of the last Hack Week was the “Summon crab!” button, and we loved it so much that we rolled it out not just for April Fools this year, but we made it our first gift-able widget in TumblrMart!

Here are some of the projects that got made for this most recent Hack Week in September. Some of these things you may also end up seeing on the site…

Tumbeast Digital Pet

Ben worked on adding our friendly server room Tumbeasts to Tumblr as a cute little digital pet. You can feed them and play with them, and they poop and get unhappy and need tending, of course. Who wouldn’t want one of these to take care of every day on Tumblr, forever and ever?

Tumblr Blaze on TumblrMart

@adalpari added Tumblr Blaze as a gift-able item in TumblrMart, which would allow folks to buy Blaze “credits” for other people. Perfect for those times you see an amazing post on Tumblr that definitely deserves to be spread around, and you don’t mind throwing some money at letting that person have a chance to spread it via Blaze!

User Account Switcher

@yi5h hacked together an account switcher for the web, so that folks can log in to more than one Tumblr account and easily switch back and forth between them. Super handy if you have one account for your roleplaying character, and another for your Star Trek fandom discussions. Very useful!

Tumblr Collections

On web as well, João made a version of an idea that’s floated around many times, the idea of being able to organize posts on Tumblr into “collections” that can be named and shared. I think everyone would very much enjoy having a collection called “waves” that’s just soothing GIFs of ocean waves.

As always, stay tuned to the @changes blog to see if any of these hacks make it on Tumblr for real!

AKA why are some of my GIFs being turned into videos?

Overview

• We’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 and use less data in almost every circumstance, with no discernible loss in quality.
• This conversion only applies to specific types of GIFs, such as ones without transparency in the first frame. We’ve tested this conversion on thousands of GIFs, and we’re still tuning it to be virtually indistinguishable from the original GIF.
• XKit’s “Vanilla Videos” extension was causing a bug with this experiment, but a recent new XKit version release has fixed that issue.
• If you’re served an MP4 instead of a GIF, clicking on the image will still open it in a lightbox, which you can download as GIFV or GIF, depending on what’s served.
• Since this is still just an experiment, there is no way to opt-out yet; adding some kind of opt-out (on the creator and/or consumer side) is a possibility though.
• If you’re served a GIF as MP4 and it looks wrong, please contact Support with a link to the image and what looks wrong about the conversion. We need examples to help us improve the experience. Also, please do not send duplicate support requests.
