Allow me to present a simple thought experiment. Suppose we didn’t need to store our code as ASCII text on disk. Could we change the way we write – and more importantly read – symbolic code? Let’s assume we have a magic code editor which can read, edit, and write anything we can imagine. Furthermore, assume we have a magic compiler which can work with the same. What would the ideal code look like?
Animation is just moving something over time. The rate at which the something moves is defined by a function called an easing equation or interpolation function. It is these equations which make something move slowly at the start and speed up, or slow down near the end. These equations give animation a more life like feel. The most common set of easing equations come from Robert Penner's book and webpage.
Software Libraries are good. They allow abstraction and encapsulation; which encourages reuse. They also allow the library to be written by one person and used by another. This is reuse at the programmer level, not just the system level. A library can be written by a person who has domain expertise but used by someone else who has less or no expertise in that domain. For example: an XML parser. The implementer knows the XML spec inside and out, but the user of the lib needs only a basic understanding of XML in order to use the lib.
Mmmwaa haa haa. It lives! I've gotten Java to run on webOS natively with a new set of Java SDL bindings. That means it just *might* time to start a new project. Read on for how it works and how you could help.
You may be a new programmer, or a web designer, or just someone who's heard the word 'RegEx', and asked: What is a Regex? How do I use it? And why does it hurt my brain? Well, relax. The doctor is in. Here's two aspirin and some water.
Most of of my free time work for the past few months has gone into Amino, the UI toolkit that Leonardo is built on, but Leo itself has gotten a few improvements as well. I'm happy to announce that the next beta of Leo is up, including:
As part of my ongoing efforts to create better designed software, I some how ended up creating my own new UI toolkit. This is really a part of my belief that a decade from now 90% of people will use phones, slates, or netbooks as their primary computing device. Amino is my experiment building software for that other 10%: the content creators who need killer desktop apps, the programmers who want great tools, and the knowledge workers who need to manage incredible amounts of information at lightning speed. Amino is the toolkit for these apps.
I have often wondered how people learn to program today. In the old days we had Basic and Logo, but what do kids use today? The old standbys are powerful enough to make something for the web (assuming they even exist) and nothing else has a simple development environment for children. Perhaps we need something new.
In my years as a professional programmer I have used many Revision Control Systems (RCSes). It's that software that manages and protects the software you use. One of the tools of the toolmaker. Many companies pay tens of thousands of dollars for this software, often licensing it per-seat, and yet a perfectly good free alternative exists: CVS. In fact I will argue that there almost no reasons not to use CVS. While there are some other RCSes which beat CVS on technical grounds like parallel development I think that CVS has the edge in everything that counts.
