Style Tiles is a website that showcases a creative approach to designing process, useful for most web designers.

Style Tiles is, in essence, an idea-based approach to designer-client communication, but there’s also something purely functional here.

A Style Tile, in its physical form, is a set of fonts, colors, and interface elements that you present to the client for him/her to decide.

Building a good Style Tile is quite fast from the PSD provided on the website — definitely faster than building a full-blown web design. This process is also a lot more precise than a blackboard concept that consists of, possibly, rectangles of suspicious shapes.

Nodetime is a performance monitoring library for Node.

Nodetime is useful for performance diagnostics, as it helps pinpointing the exact cause of performance problems.

Nodetime parses client requests, and allows you to see how much the request uses from server resources.

The app is quite sophisticated, as it automatically runs in debug mode under virtually no load, but, in production, it only sends the slowest requests to the server.
