SQLite is very carefully tested prior to every release and has a reputation for being very reliable. Most of the SQLite source code is devoted purely to testing and verification. An automated test suite runs millions and millions of test cases involving hundreds of millions of individual SQL statements and achieves 100% branch test coverage . SQLite responds gracefully to memory allocation failures and disk I/O errors. Transactions are ACID even if interrupted by system crashes or power failures. All of this is verified by the automated tests using special test harnesses which simulate system failures. Of course, even with all this testing, there are still bugs. But unlike some similar projects (especially commercial competitors) SQLite is open and honest about all bugs and provides bugs lists and minute-by-minute chronologies of code changes.
Sometimes it’s tempting to use webkit’s drawing features, like -webkit-gradient, when it’s not actually necessary - maintaining images and dealing with Photoshop and drawing tools can be a hassle. However, using CSS for those tasks moves that hassle from the designer’s computer to the target’s CPU. Gradients, shadows, and other decorations in CSS should be used only when necessary (. when the shape is dynamic based on the content) - **otherwise, static images are always faster**. On very low-end platforms, it’s even advised to use static images for some of the text if possible.
