    Ryan Johnson

    tl;dr: You have to access the specific site’s cache information by using a button to the left of the URL in your browser. In most browsers, this should be a little lock icon for “security”.

    Date: July 12, 2020 (2020-07-12) Until this year, the Haskell Platform shipped with the WinGHCi interpreter, a GUI version of the GHCi command line interpreter.

  • Symbols in computer science

    •

    Ryan Johnson

    Computer scientists need a system of symbols to simplify and unify the expression of concepts, and thereby reduce the complexity of the development process. Programmers have been stuck using the same symbols as typists for 50 years, because, in the beginning, it was expensive to make a separate keyboard for programming and for typing,…

    Recently I started working on a startup tech business to implement some of my tech ideas. I got a work-space on campus at University of Memphis and they gave me a desk and computer to work on in a shared work-space area where other entrepreneurs are working.

  • Set Theory in Programming

    •

    Ryan Johnson

    In high school and college math courses, we learn about ways to express groups of items as subsets and supersets. This branch of mathematics is called set theory. The expression, X ∈ A means “Item X exists in set A”, or “X is an element of set A”. The symbol looks like an E,…

  • Haskell and functions

    •

    Ryan Johnson

    The following is a pair of commands in Haskell that creates a list of numbers and performs a calculation on that list to generate a new list. This is called a list-comprehension. The first statement can be read as Define list_1to100 as a list from 1 to 100, but don’t actually generate a list…

    Ryan Johnson

    In 2019, during my research into finding or making a dream language, I gave a presentation and prepared a slideshow at the local .NET User Group about the history and future of programming. The presentation covers the early history of programming paradigms and the evolution of C-like languages from Label/Goto jump statements to the…

  • NixOS and the Linux distribution as a “channel”

    •

    Ryan Johnson

    I am currently installing and setting up NixOS, a GNU-Linux distribution that lets you configure your system and install apps using a configuration file. The configuration/installation is written in a language of its own called Nix, which is a pure functional language (PFL). If this sounds scary, don’t worry. It’s basically a configuration file…
