This is a tumblelog, kinda like a blog but with short-form, mixed-media posts with stuff I like. Scroll down a bit to start reading, or a bit more to read more about me.

Gotta love a simple solution.
By Chris Ruppel, writing at Four Kitchens; a case study to back up the spirit of Adam Sontag’s “one less JPG” statement.
A deck by Wesley Hales. Looks like a good round up — and/but as usual: I wished I could hear the talk that goes along with it. For one thing, it would be nice to know whether/not he addresses some of the limitations that PhantomJS has w/r/t/ reporting (or not reporting) cached assets in a given page’s payload. But overall it looks like some solid recommendations.
BrowserDiet.com: a pretty good list of performance tips for front-end developers. The nuance is mostly there (if you want to get nit-picky…) and for the most part the discuss the pros/cons of the different approaches. Worth a look, and the fun format makes it accessible to even junior and/or “incidental” web developers.
By “bluesmoon” at the lognormal blog (via a Nicholas Zakas tweet). It’s pretty intense stuff, and is a pretty interesting approach to the problem of trying to load scripts in a non-blocking fashion (if maybe a bit overkill?). The bit with the iframes makes my skin crawl a bit — not that there’s anything wrong with iframes deep down, but when you spend enough time with them, you start to feel their gritty edges. Anyway: this is a cool technique, and you should check it out, but be on the look-out for the hairy parts.
By Eberhard Gräther, writing at HTML5Rocks. Awesome new performance profiling tools in Chrome Canary.
Great in-depth piece by Marc Grabanski on the front-end performance optimizations that they did with the Sprint.ly UI. Includes some detailed discussion of Backbone.js view rendering and its pitfalls. He says it’s a pretty high-level discussion, but I don’t know… It gets pretty technical, if you ask me. Their lazy-loading solution is a work of art.
Ilya Grigorik. tl;dr: not all stylesheets are blocking, and here’s how to tell the difference between one that is, and one that isn’t. (Also: he beats the “compress your images!” drum again in here.)
