Racket is a general purpose programming language derived from Lisp. It is called a "programmable programming language" because its built-in macro system allows a programmer to redefine everything about the lang
Lisp, an acronym forlist processing, is a functional programming language that was designed for easy manipulation of data strings. As one of the oldest programming languages still in use, Lisp offers several different dialects and has influenced the development of other languages. A unique feature ...
Racket. Originally known as PLT Scheme, Racket is a descendant of Scheme designed for both scripting and general-purpose programming. It is notable for its emphasis on creating new programming languages and its extensive libraries and tools for software development. Racket is often used in education...
The code is verbose if it contains an excessive number of words. Long, convoluted statements may appear helpful while learning a new language, but they reduce code’s readability and scannability. Many advanced languages create too much of a racket in an attempt to sound like English. Java, ...
Given the ubiquity and diversity of these cyber-attacks, businesses around the world are in critical danger of falling prey to this digital-age extortion racket. How does ransomware work? As with any malicious software, ransomware can enter your network a number of different ways, such as throug...
Computer science is not quite engineering. But, it's close enough. Computer scientistswillfind themselves working with engineers. Computer scientists and traditional engineers need to speak the same language--a language rooted in real analysis, linear algebra, probability and physics. ...
(or interview.) That’s a rare resume writer, if you can find one amidst the marketing of all who offer “free resume reviews.” A few years ago one big resume racket was exposed after customers got their free reviews, paid for re-writes, the submitted those back for review… only ...
If we attempt to simply(define (f x) (+ x 1)), we get an error “f: unbound identifier in module”. The reason for this is Racket’s phase distinction. If we(define f...),fis arun-timeexpression, and run-time expressions cannot be used atcompile-time, which is when the macro ...
A name is an arrow: a link from arrow tail (reference) to arrow head (binding). (Or as compiler hackers prefer to say, from “use” to “def”) Some people take this arrow idea quite literally—for example, theRacketlanguage’s development environment will show you these links as actual...
This is what I tell her about college.* You don’t have to go to college immediately after high school. Take a gap year to work and travel and figure out what you want out of your college experience –please!Go teach English for a year in Asia. Join the PeaceCorp for a couple year...
