C Program to Plot the Gamma Function in the Terminal

Plotting the gamma function in the terminal

In this post I want to talk about a C program I wrote just recently that plots a mathematical function - specifically the gamma function. I think it's worth looking at, because this program demonstrates how to handle the various aspects of graphing and plotting using just ASCII characters in the terminal. The program draws … Continue reading C Program to Plot the Gamma Function in the Terminal

C Program to Generate a Blank MS-DOS Floppy Image in Linux

How do you do, fellow old-timers? Today's post is going to be a bit of a crossover, because I'm going to get into some programming stuff, some Linux stuff, and some DOS stuff all at the same time. I'm going to show you a program that I wrote a while back that uses POSIX API … Continue reading C Program to Generate a Blank MS-DOS Floppy Image in Linux

My (Revised) Step-by-Step Process for Starting Arch Linux Live

In this post I talked about my process for setting up my Arch Linux live system. I still use a live distro (mostly because I don't want to overwrite any files currently on the hard drive), but in the last few months I've made quite a few revisions to my startup process for Arch Linux … Continue reading My (Revised) Step-by-Step Process for Starting Arch Linux Live

Exploring Borland Turbo Pascal for DOS

Picture of Blaise Pascal

I've been having some more adventures in VirtualBox, messing around with DOS software. This time I thought I'd explore Borland Turbo Pascal. I have an affinity for ancient programming languages - Pascal, Fortran, BASIC, Lisp, etc. I like them for basically the same reason I like vintage computers and old operating systems. It's like exploring … Continue reading Exploring Borland Turbo Pascal for DOS

Obfuscated Unix Scripting with dc

dc, an elegant calculator for the Unix time sharing system

So I realized that I liked the concept behind Obfuscated Unix Scripting with sed and I thought I'd make a series. There are a number of scripting languages native to Unix, and many of them qualify as being what you would call "obfuscated". One such language is the classic Unix calculator known as dc. This … Continue reading Obfuscated Unix Scripting with dc

Doing Statistics in awk

Statistics in awk

One exercise that offers a lot of interesting challenges in coding is to use a programming language for an application that it's not intended to be used for. Writing a Fortran compiler in TECO and solving the Towers of Hanoi problem in the troff text formatter are two examples from the legendary Hacker Purity Test. … Continue reading Doing Statistics in awk

Analyzing Twitter Analytics Data in R

Analyzing Twitter Analytics Data in R

I've spent a lot of time trying to figure out how to become popular on Twitter. It's pretty much impossible if you're not already a celebrity or public figure, but I figured I'd try to maximize my success anyway. I did some data analysis using CSV data that I exported from the Twitter Analytics page. … Continue reading Analyzing Twitter Analytics Data in R

Adding Set Types to the C Programming Language

Well, it's been over a month since my last post, so it's high time I got back into it. I kinda got distracted by other stuff on other sites, most notably DeviantArt and Discord. But I'm back now, and hopefully I'll be able to post more consistently in the future. This is my third article … Continue reading Adding Set Types to the C Programming Language

Data Science in C: Combining CSV with SQL

In the last episode of Data Science in C I talked about the parser portion of my CSV library, which I implemented using automata. Now that we've parsed the CSV code and converted it into an abstract table structure, it's time to implement some operations on the table data so that we can actually use … Continue reading Data Science in C: Combining CSV with SQL
