Introduction to Computer Programming - Applets BFOIT - Introduction to Computer Programming Welcome to BFOIT's Introduction to Computer Programming website. This is a short screencast overview of the first lesson: What is Computer Programming? Computer programming is composing/authoring of a process/procedure for doing something, BUT IN INCREDIBLE DETAIL. proc-ess / Noun: A series of actions or steps taken to achieve an end. pro-ce-dure / Noun: A series of actions conducted in a certain order or manner. In a more advanced world (science fiction today) it will be possible to teach the computer to do something by describing what it is that you want in your native language, English in my case. But, as of now, this is pretty much fantasy.

Ian's Blog: Bury it under the noise floor (Steganography) Bury it under the noise floor (Steganography) 2013-03-22 01:59 by Ian Here is discussed a PHP program to hide encrypted messages and files inside of images without significantly changing the way the image looks. This is meant to be an instructional write-up to touch on some common ideas and mechanisms in cryptography. Source code: steg-img.zipI also have a repo out at GitHub. A test-fixture for the program can be used at this location. Notable features: AES-256 encrypted with optional BZ2 compression.Multi-round password hashing to derive key material from passwords.No predictable patterns to search for. Potential Uses: Hiding data and messages (bitcoins / password lists / etc).Watermarking intellectual propertyDelivery of executable payloads (think: javascript/PHP + eval()) Some constraints: The modulated carrier must remain as it was output. Here are some examples of images that are well-suited for hiding data in this manner... These images are ill-suited for hiding data...

Introduction to Computer Programming - Preface These web-based notes are the result of classes that I have been involved with over the past few years. I started putting them together simply as notes for my students. From 1999 through 2002, I taught an Introduction to Programming class using the Java programming language to 6th through 8th grade students at Berkeley's Longfellow Arts & Technology Middle School. Starting in the summer of 2000, I volunteered to work with Brian Harvey, participating in the BFOIT Introduction to Computer Science program. The Longfellow Java class was held on Saturday mornings, from 9:00am to 11:00am. The BFOIT class started out as a single week, with Introduction to Programming taught every morning from 9:00 to 12:00. In the summer of 2001, BFOIT was extended to two weeks. For the summer of 2002, I combined the Turtle Graphics commands available in Logo with the Java programming language. For the 2004 BFOIT class the web notes were expanded to cover a wider variety of computer science topics.
