Turning raster images into SVG files, one pixel at a time. Yes, really.
The PHP accepts a raster image (GIF, PNG, JPEG, that sort of thing) and creates an SVG image that recreates the raster image. It does this by drawing filled rectangles to recreate the pixels in the image. In many cases, this is literally a 1-by-1 rectangle, but it will check for runs of similar color (similar to GIF compression) and create one rectangle per run. It checks both horizontal and vertical runs to see which approach is more efficient, and returns the better option.
The script requires GD.
There are situations where people want to take small bitmaps—think primary-color buttons or badges—and make them scalable while still preserving their 8-bit appearance. See, for example, Joe Crawford’s post about upscaling a minitag. For those cases, this script will enable a quick conversion to SVG with at least some minimal attempts at optimization.
This all originally started as a one-off experiment and a bit of a jape. You can see the original at flaming-shame, if you fancy a laugh.
Almost all projects involve some form of dialog window at one point or another. However, accessibility is all too often set aside in favor of quick implementation. Truth is, accessible dialog windows are hard. Very hard.
However, his version—no matter how good it is—requires jQuery. We try to avoid using jQuery as much as we can here. We realised we did not really need it most of the time. On top of that, his script is not very flexible: only one dialog window per page, hard-coded IDs inside the functions. Not very practical and certainly not a drop-in script for any project.
So I rolled up my sleeves and improved it.
Copying text to the clipboard shouldn’t be hard. It shouldn’t require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn’t depend on Flash or any bloated framework.
That’s why clipboard.js exists.
While working on some projects last year, we realized that if we had a more user-friendly, markup-based approach to configuring our SVG animations, we’d be more productive, and our clients could easily work with their own animations after hand-off as well. So we built an open-source tool!
LayerSnap is a script that builds on top of Snap SVG to build simple SVG animations by editing the SVG markup’s attributes. It comes with a suite of pre-set build transitions like “fade”, “move-down”, “enter-left”, “rotate-right”, etc. It also has an “anvil” transition, because no animation toolkit is complete without an anvil transition. These transitions can be configured via an attribute on every group (
g) element in an SVG, and a special syntax allows you to combine each transition with a host of configuration settings for their speed, delay, easing, looping, repeating, and even interactivity.

Portier (pronounced “Por-tee-ay”) is a self-hostable login service that you can use instead of passwords. Portier sits between your website and third-party services like Google Sign-In to provide your users the fastest and easiest login experience, without ever needing a new password.
Best of all, Portier works for everyone, because it can fall back to traditional “click the link” methods of email confirmation.
Email-first: Email addresses are decentralized, self-hostable, and useful on their own, so Portier uses email addresses instead of usernames to identify users.
Connected: Whenever possible, Portier integrates with major APIs like Google Sign-In to provide seamless, in-browser identity verification.
Decentralized: Anyone can host their own Portier Broker; there are no centralized dependencies.
Open and Transparent: Because Portier uses email addresses, there is never any lock-in.
