The Compression Problem Computational Thinking in This Discussion, We Will Look at the Compression Problem
Squeezing Ten Pounds of Data in a Five Pound Sack - or - The Compression Problem Computational Thinking In this discussion, we will look at the compression problem. Along the way, we will see several examples of computational thinking: • representations allow the computer to store and work with letters, images, or music by representing them with a numeric code; • patterns or repeated strings in text can be used by a computer for compres- sion; • index tables allow us to replace a long idea with a short word or number; Reading assignment Read Chapter 7, pages 105{121, \9 Algorithms that Changed the Future". The Compression Problem for Traveling When you pack for a trip, you want to minimize the number of suitcases and bags you take, but maximize the things you can transport. Sometimes it takes several repackings, rolling and squashing and rearranging, before you are satisfied. The Compression Problem for File Storage Your computer hard disk has a limited amount of storage. The information in a single movie or song could easily fill up your entire computer memory. This doesn't happen because the information is compressed in several ways. The Compression Problem for Data Transmission Data must be transferred from one place to another, over networks with limited capacity. In North America, 70% of Internet traffic involves services that are streaming data, such as movies or music. When the local network is overloaded, a movie becomes unwatchable, music becomes noise, users are dissatisfied. Solving the compression problem with more capacity One solution to these problems is to increase capacity: Buy more suitcases or bigger ones. -

A Look at Telegraph Codes
Compression, Correction, Confidentiality, and Comprehension: A Look at Telegraph Codes Steven M. Bellovin Columbia University [email protected] Abstract Telegraph codes are a more-or-less forgotten part of technological history. In their day, though, they were ubiquitous and sophisticated. They also laid the groundwork for many of today’s communications technologies, including encryption, compression, and error correction. Beyond that, reading them pro- vides a snapshot into culture. We look back, describing them in modern terms, and noting some of the tradeoffs considered. 1 Introduction Most cryptologists have heard of telegraph codes. Often, though, our knowledge is cursory. We’ve forgotten what we read in Kahn [9], and perhaps remember little more than the basic concept: a word, phrase, or sentence is represented by a single codeword. In fact, telegraph codes were far more sophisticated, and laid the groundwork for many later, fundamental advances. Looked at analytically, telegraph codes fulfilled four primary functions: compression, correction, confi- dentiality, and comprehension. Beyond that, they offer a window into the past: the phrases they can be used to represent give insight into daily lives of the time. This paper, based primarily on my own small collection of codebooks, illustrates some of these points. For typographical simplicity, I have written codewords LIKE THIS, while plaintext is written this way. 2 Compression Compression was the original goal of telegraph codes. Early trans-Atlantic telegrams were extremely expen- sive — $100 for twenty words in 1866 [8] — so brevity was very important. Early telegraph codes had two ancestors, codes for semaphore networks and naval signaling [9]. -

' «i -•aif -ISe • 1-b Publication of the Letter DEPARTMENT OF COM'lERCE Circular BUREAU OF STANDARDS LC 45 WASHINGTON, D. 0. CONSTRUCTION AND OPERATION OF A SIMPLE RAD IOTELEGP.APHI C CODE PRACTICE SET.* (Prepared at request of the States Relations Service, United States Department of Agriculture for use by Boys 1 and Girls 1 Radio Clubs.) Introduction This pamphlet describes apparatus which may be used for the pur- pose of learning the radio telegraph code. The apparatus is very easy to set up and operate. It is intended to be used at radio club meet- ing places or in places where a number of radio students are accustomed to assemble. Those who construct the simple radio receiving sets des- cribed in the first two pamphlets of this series will probably hear many signals which are in code. The Code Practice Set is therefore made a part of this series so shat the international Morse Code may be learned. The cost of the complete outfit will be about $5*70 or, if one constructs the telegraph key, she. cost will be reduced to about $3«b0 It is assumed that those who use this outfit have radio receiving sets and can bring their telephone receivers (“phones") to connect to the other apparatus. It is also assumed that it will not be necessary to purchase the table upon which the parts are mounted. It is desirable *This is the third of a series of pamphlets describing the construction of radio equipment. The two publications which nave been issued are Letter Receiving Circular 43 , "Construction and Opera-cion of a Very Simple Radio Equipment," and Letter Circular 44, "Construction and Operation of a Two- Circuit Radio Receiving Equipment with Crystal Detector." These describe the construction and operation of simple receiving sets. -
