Convert Photoshop Drop Shadows to CSS3 Box and Text Shadows This tool creates CSS3 Box Shadows based off of Photoshop Drop Shadow settings.

Richard Feynman, the Challenger Disaster, and Software Engineering : Gustavo Duarte With respect to software, I take out four main points: Engineering can only be as good as its relationship with management Big design up front is foolish Software has much in common with other engineering disciplines Reliable systems are built by rigorously tested , incremental bottom-up engineering with an ‘attitude of highest quality’

Frida Inject JavaScript to explore native apps on Windows, Mac, Linux and iOS. Scriptable Your own scripts get injected into black box processes to execute custom debugging logic. Hook any function, spy on crypto APIs or trace private application code, no source code needed! Stalking Stealthy code tracing without relying on software or hardware breakpoints. Think DTrace in user-space, based on dynamic recompilation, like DynamoRIO and PIN .

Type-System Criteria · ongoing by Tim Bray Cri­te­ria Let’s call them the Bánffy-Bray cri­te­ria for se­lect­ing be­tween sta­tic and dy­namic type sys­tems. Sta­tic typ­ing’s at­trac­tive­ness is a di­rect func­tion (and dy­namic typ­ing’s an in­verse func­tion) of API sur­face size. Dy­namic typ­ing’s at­trac­tive­ness is a di­rect func­tion (and sta­tic typ­ing’s an in­verse func­tion) of unit test­ing work­a­bil­ity.

Code Like a Chef: Work Clean | The Table XI Blog Interesting concept, specially the part gotten from the Ad Hoc at Home cooking book (by Thomas Keller ), which got me to dig out for the full text snippet ( emphasis added): Being organized – as we say in our kitchen, working clean – is a skill to develop. We call it mise-en-place , French for, literally, ‘put in place.’ The term can be very specific, referring to ingredients needed to complete a recipe, measured out and ready to use, or it can be more general: are you organized, do you have everything you need to accomplish the task at hand? ...

Creators need an immediate connection with what they’re making Bret Victor ’s guiding principle (via his talk Inventing on Principle )

Myth – CSS the way it was imagined. Myth is a preprocessor that lets you write pure CSS without having to worry about slow browser support, or even slow spec approval. It’s like a CSS polyfill. Variables : The same syntax from the CSS spec, using the var() function . Math : The same syntax from the CSS spec, using the calc() function . Color Manipulation : Straight from Tab Atkins’s draft for a future version of the spec. No Prefixes : Prefixes for common browsers are automatically added, so you don’t need worry.
