Pseudocode

Most software programs are developed using a programming language, like C++ or Java. These languages have a specific syntax that must be adhered to when writing program's source code. Pseudocode, on the other hand, is not a programming language, but simply an informal way of describing a program. It does not require strict syntax, but instead serves as a general representation of a program's functions.

Since each programming language uses a unique syntax structure, understanding the code of multiple languages can be difficult. Pseudocode remedies this problem by using conventional syntax and basic english phrases that are universally understood. For example, a line of PHP code may read:if ($i < 10) { i++; }

This could be written in pseudocode as:if i is less than 10, increment i by 1.

By describing a program in pseudocode, programmers of all types of languages can understand the function of a program.

Pseudocode is an informal language, so it is mainly used for creating an outline or a rough draft of a program. Because it is not an actual programming language, pseudocode cannot be compiled into an executable program. Therefore, pseudocode must be converted into a specific programming language if it is to become an usable application.

Push

Push refers to a system in which data is "pushed" to a user's device rather than "pulled" by the user. In other words, the data transfer is initiated by the server rather than the client.

Push technology, which is also called "server push," can be used to send news data, stock updates, and other information from the Internet to a user's computer. It is also used to send text messages via SMS to people's cell phones. Push e-mail allows users to receive e-mail messages without having to check their e-mail manually. This means new messages appear on the client's device as soon as they are received by the server. However, in order to receive pushed messages, both the mail server and the user's e-mail client must support push technology.

While most information is still "pulled" from the Internet, more kinds of data can now be pushed to users' systems. With push technology, people no longer need to constantly check news sites, e-mail, or other data sources to see if they have been updated. The result is a more efficient means of receiving information. If only we could go back in time and tell the playground bully, "Don't push me, push your e-mail." That would show him.

Python

Example: "The developer created several extensions for Autodesk Maya using Python."

Python is a programming language commonly used for creating Web applications and software plug-ins. It is designed to be highly readable with an uncluttered visual appearance. Python is similar to other scripting languages like Perl and PHP, but uses English words more frequently and has less punctuation. Programs written in Python can be saved as basic scripts (with a .PY file extension) or compiled programs (with a .PYC extension).

Python is installed on nearly all Unix-based systems, including Mac OS X, and can be run from the terminal. Therefore, if you find out Python is on your computer, don't be scared. It's not a snake, just a programming language.
