Speaking of D3, Mozilla open sourced a library they use on top of D3 to visualize time-series data in a “principled, consistent and responsive way.”
If you’re serious about visualizations, you’ll still want to learn D3 itself, but it’s great when we can optimize and simplify common use cases. That’s exactly what MetricsGraphics.js does. Here’s a taste:
Check out all of the examples of what’s possible here:
Have you ever seen a rad D3 visualization and wondered what the data that created it looks like in its raw form? You’re in luck! D3 Deconstructor, a Chrome extension from UC Berkeley’s VisLab, does exactly that.
Why might you want to do this, you ask? In Elle’s case, she demonstrates the editable sections of her Jekyll theme with it.

CSS Dig gives you a new way to analyze your CSS (using Google Chrome).
Consolidate, refactor, and gawk at the 37 shades of blue your site somehow ended up with. CSS Dig is a Chrome Extension that looks for stylesheets and style blocks on the webpage it’s run against and groups declarations together for easy inspection. For example, you can see how many colors are used and how often. This can help you consolidate your styles and help with refactors.
The homepage is helpful to get started, but the code is on GitHub.

Speaking of PostgreSQL, ToroDB is a JSON database that runs on top of Postgres.
JSON documents are stored relationally, not as a blob/jsonb. This leads to significant storage and I/O savings. It speaks natively the MongoDB protocol, meaning that it can be used with any mongo-compatible client.
MongoDB client compatibility. Smart. Still early days, though:
ToroDB follows a RERO (Release Early, Release Often) policy. Current version is considered a “developer preview” and hence is not suitable for production use. However, any feedback, contributions, help and/or patches are very welcome.
PostgreSQL is — hands-down — my favorite persistence engine. However, it has long lacked the tooling of its alternatives. Tools like pgweb are changing that story.
This is a web-based browser for PostgreSQL database server. It’s written in Go and works on Mac OSX, Linux and Windows machines… This project is an attempt to create a very simple and portable application to work with PostgreSQL databases.
ProgressBar.js is yet another JS lib that makes good use of SVG:
With ProgressBar.js, it’s easy to create arbitrary shaped progress bars. This library provides a few built‑in shapes like Line, Circle and Square but you can also create your own progress bars with Illustrator or any vector graphic editor.
In case you are wondering: yes, you can even bring your Goroutines along for the ride. Give it a Go (spluh!) on the GopherJS Playground.
Pageres is an Awesome CLI (and JS API) from Sindre Sorhus & Kevin Mårtensson that captures screenshots of websites at different resolutions. Looks like a great way to make sure your site is adequately responsive. Check it.

Great idea and solid execution on a less intrusive responsive Lightbox:
Strip is a Lightbox that only partially covers the page. This makes it less intrusive and leaves room to interact with the page on larger screens while giving smaller mobile devices the classic Lightbox experience.
Check out the demos on the Strip homepage to see what the buzz is all about.
SweetAlert is an easy way to turn those boring, built-in browser
confirm() dialogs into something much shinier and user-friendly.

Have you ever yelled? “Why is this site soooo slow!?!” Well, that doesn’t happen when you host your Rails app with Ninefold.
A powerful command-line tool married to a slick GUI is a beautiful thing. Sindre Sorhus’ gulp-app is just that.
It’s OS X only at the moment, but expansion to other operating systems is on the road map.
Cool Ruby gem from the team at Stripe which makes it easy to run multiple copies of a single long-lived process. From their announcement post:
Einhorn makes it easy to have multiple instances of an application server listen on the same port. You can also seamlessly restart your workers without dropping any requests. Einhorn requires minimal application-level support, making it easy to use with an existing project.
I’m going to take a seriously look at Einhorn before deploying my next app.
