Binary Code Toolkit 與 ReasonLines 使用情況與統計
Use this beautifully designed app to introduce the binary code and how it works. The app presents all the letters of the English alphabet as well as the numbers from zero to 9. Learning to use the binary code is an fun way to send secret messages to your friends. It is also a way for teachers to introduce the history of computers and basic concepts related to Boolean logic and ASCII. Learning about the binary representation of data is important because it is an essential concept in computer science. It also provides a fundamental understanding regarding how communication is possible between computers using the Amercan Standard Code for Information Interchange (ASCII). The adoption of this universal code made the digital revolution possible. It was an important step that helped in the expansion of digital technology.
The Binary Code Toolkit is an interactive learning tool for introducing how the system is used to represent meaningful data with a series of 0's and 1's. Bob Bemer developed the ASCII coding system to standardize the way computers represent letters, numbers, punctuation marks and some control codes. He also introduced the backslash and escape key to the world of computers and was one of the first to warn about the dangers of the millennium bug. The millenium bug was a problem related to the need to use additional bits to represent the correct year on a computer after the turn of the century.
When using the app In the exploration mode users can press any key and see the how to represent the associated letter using just 0's and 1's. Using the keyboard students can practice speeling words using the binary code. Switch to the number mode to learn how to represent the digits from zero to 9. Press any key in this mode and see how to represent a digit using a series of 0's and 1's.
Students who are learning about the binary code will find the quiz feature helpful. After pressing the question mark to start the quiz a word is randomly selected from a list of words. The way to spell the word using using bits and bytes is shown. The object is for the student to recognize the on and off LED's that represent the characters in the word and to type them on the keyboard.
Speech effects are provided so that when a letter is pressed on the keyboard it is pronounced aloud. This feature can optionally be turned on or off.

ReasonLines provides (1) a new and easier approach to the traditional syllogism and (2) an expansion of the traditional syllogism to include numerical quantification.
1)The new approach to the traditional syllogism
Instead of considering isolated statements as the components of arguments, such as major premise, minor premise, and conclusion, this new approach bundles each statement with its equivalents and each bundle is represented by its own “schematic” of arrows. The premise schematics can then be dropped in place along side each other where their juxtaposition displays whatever conclusion, if any, is entailed. The user only needs to learn how to select the correct premise schematics and how to follow the arrows for a conclusion.
Part One of the Help page is a tutorial for this new approach.
(2)The numerical expansion of the traditional syllogism
It is already standard to interpret the particular quantifier numerically; that is, it is standard to take “some” as “at least one.” Moreover, the universal quantifiers, “all” and “no,” can also be faithfully rendered numerically since “all” means “all with zero exception” and “no” means none “none with zero exception.” Given this, it turns out that the traditional quantifiers simply mark the beginnings of endless possible quantifications since “at least one” opens the series of “at least two,” “at least three,” etc., and “all (none) but zero” opens “all (none) but one,” “all (none) but two,” etc.
By making this explicit, the zero and one of traditional syllogisms become replaceable by other numbers. So, for example, “All but 10 A are B and all but 20 B are C, so All but 30 A are C,” and “At least 100 A are B, All but 7 B are C, so At least 93 A are C,” are just as valid as the traditional Barbara and Darii, and for the very same reason.
Part Two of the Help page develops this numerical expansion by appealing to the schematics.
