The relevance of life is irrefutable

Chad was concerned about what the young boy Simon had said to Luke regarding the flood in Genesis. Sure, he knew about the story, but when Luke told the children about God killing all the animals with a flood, something in him broke. How could he know what stories were true or not? He decided to focus more on the teachings of Jesus and began reading the Bible more and also doing other…

The 3 integer sequence programs from the DOS Assembly Arithmetic Algorithms have now been added to the Linux version. What was Chapter 5 for the DOS book is now Chapter 17 for the Linux book. I am not sure whether readers prefer this content sooner or later in the book but I felt that I had a lot more ground to cover in the Linux book and so I spent 16 chapters explaining the system calls and why…

I wrote another program which is actually a modification of chastack. This gets input from a user while it is running. Despite how simple it may seem, I had to work at reading from the keyboard because there are multiple ways to read a string from the user. I may add more to this program later, but it has all the important functions of a stack based calculator. Here is a screenshot that shows me…

This post is a chapter from my recently published Linux edition of Assembly Arithmetic Algorithms. The story behind why I wrote the program featured in chapter 15 goes back to when I discovered how to cheat at video games. This story is worth sharing to inspire the next generation of gamers to learn computer math and programming just as I did. Chapter 15: chastecmp In this chapter, I will show…

I had just finished the 14th chapter of the Linux edition of Assembly Arithmetic Algorithms, and then I took a look at some old source code where I had learned enough of the ELF format to create my own ELF headers using either FASM or NASM. The differences between these two assemblers make them incompatible with each other. Still, I have made four separate gists on GitHub so that if someone wants…

putchar int putchar(int c); What does this function do? Writes 1 character to standard output (terminal or redirected to file). When would you use this function? When you need to write a simple character for formatting, such as a space, tab, newline, etc. to separate the output of other output functions like printf or fwrite. To print a specific range of characters in a loop. Where in your…

I have converted my chastext program to 64 bit Assembly for Linux. Next to chastehex, this is the program I am most proud of because it can find and replace exact strings of text. It isn’t quite the same as the Linux “sed” tool, but it is faster, smaller, and I wrote it myself and can do whatever I want with it. So of course what I did was write shell script to show what it is capable…

Chad was hard at work finding Bible stories he could tell the kids while they ate after soccer. He had managed to speak the story from Daniel chapter 1 in his own words, which made more sense than how it sounded in the King James Bible. Meanwhile, Luke was also busy picking his own set of Bible stories. He was looking for something he could use to fight against Chad’s Vegan diet and also justify…

This post is the source of the 64-bit edition of chastecmp, my file comparison tool. It behaves exactly the same as the 32-bit edition. However, I am slowly translating my best programs to use the 64-bit calling convention for the eventual 64-bit edition of my book. This will be a few years away but there is not too much work that needs to be done. Mostly I just have to use different registers…

A programmer is not a magician They just know how to use addition Those with skill and high ambition Don’t hesitate to break tradition Reverse addition is subtraction There is no need for fancy abstraction Do not fall for hype and distraction Don’t hesitate to learn, take action Repeated addition is called multiplication Despite its badly taught reputation Teaching math is my obligation With my…

Define Abomination Various Laws that were called Abominations Are some sins worse than others What is sin? Picking out sin that are popular to criticize by heterosexual people, but ignoring others that were considered as abominations.

I have created a small prototype of a calculator in the C programming language. It is a stack based calculator similar to the forth programming language. It is written in C as a testing ground but uses methods designed to be translatable to Assembly language. It will be a featured program in chapter ten of my Linux Assembly book. main.c #include <stdio.h> #include <string.h> #include…

The most potent weapon against the lesbian and gay community has been the stereotypes that we have ourselves aided in creating. Our parades are videotaped, but only our campiest brethren are not edited out; our statements are recorded, but only the most extreme are heard; our disagreements are noted, but only the most politically correct are not filtered out. We find ourselves portrayed as an…

This post is a preview of the Linux version of Assembly Arithmetic Algorithms. It is planned to be bigger than the DOS book was and so far I am up to chapter 8 and trying to explain everything I can for Linux users who want to write assembly for modern computers at a speed higher than what was possible using a DOS emulator. The first seven chapters have been about teaching the basics of Assembly…

Consider this situation: A man chooses to have sex with a woman who he knows will go for an abortion if she gets pregnant. She does get pregnant. She goes to an abortionist, who performs the abortion. Which of the three people killed the baby? The father, mother, or abortionist? It should be obvious that all three people played a part in the abortion. So no matter what your answer, you are…

I used my new getarg function I wrote to improve the DOS version of chastext. Nothing about the behavior of the program has changed but the code is a lot smaller and more readable. This chastext program was the original reason I wrote the chastearg program. I needed to get the command line arguments just write. But more importantly, people may not see the value of the chastext program and why it…

The chastearg program, which is shortened to chastarg to respect DOS 8.3 filename limits, is a tool for separating command line arguments into multiple lines except preserving those that are quoted and therefore counting as one argument. Quoted strings will print on the same line. A key aspect of how this works is the new “getarg” function that I wrote. If you take a look at this small program…
