Timezones and DST in Oracle APEX

Almost all APEX applications I’ve been working with recently are used across multiple timezones, where many timezones uses DST (Daylight Saving Time) – that is basically almost all Europe and North America.

Good Book About Javascript

I’ve have been working with Javascript here and there – always small pieces –  as I know Java, C, Python I though that I do not need to learn anything special about Javascript, that I should be able to manage right away – In fact I somehow did, but I’ve been always bit struggling with some strange behaviours.   Having to write couple of Firefox add-ons recently I decided to read some book about Javascript to shed a light on those anomalies  –   I found this book very good – Javascript: The Good Parts by Douglas Crockford.

It relatively small book – I’ve read it in a few hours, but it gives you very good overview of all features of the language and show you how to write good and maintainable code in JS.   Now I know that Javascript is very expressive language, where I can use some powerful features like functional programming, prototypes etc.
