My VPN Experience

Posted on January 6, 2023

Introduction I was recommended some videos and I’ve been very interested to watch them. However they’re not available outside of a specific country due to geographic restrictions. This is a common problem and pretty much every commercial VPN service advertises this as a major reason to use their VPN.... Continue reading

CSO Compression and Decompression Tool

Posted on November 21, 2022

Introduction I have a number of backed up ISO files that were taking up quite a bit of space. I wanted to save some space and I decided to compress them. Instead of putting them into something like a ZIP archive, I decided that compressing into CSO would be... Continue reading

Lua Template Engine Yet Again

Posted on August 28, 2022

Introduction After writing a template engine in Lua, I found some deficiencies and wrote a few more iterations. After having used the template engine for quite a while, I’ve made a few enhancements and some fixes. This is hopefully the final version of the template engine. <h1... Continue reading

macOS USB Enumeration in C

Posted on December 6, 2020

Introduction Apple provides documentation for using IOKit, but it’s not very clear how to do a number of things. Descriptions and relationships of functions often isn’t clear. While there are examples, they tend to be lacking. The generic types IOKit uses doesn’t help either because you could have multiple... Continue reading

macOS IOHIDManager Permission Issue

Posted on November 8, 2020

Introduction The other day I was working with a USB-HID device and I thought my machine was starting to act funny. I could use the device no problem in a Windows VM but whenever my application tried to use the device, it was unable to open it. At this... Continue reading

C if Statement Evaluation

Posted on October 20, 2020

Introduction One of the bad things that the C language allows is setting variables and calling functions directly in an if statement. This should be avoided due to how the statement can exit early stopping some of the logic from happening. That said, this can also be... Continue reading

Full Text Search with Jekyll

Posted on June 10, 2020

Introduction When I switched from WordPress to Jekyll I gave up searching posts. I knew this was a limitation of running a static site and I didn’t think it would be too big a deal. After a year I’ve found I actually look up some old reference posts... Continue reading

Making and Using C plugins

Posted on May 12, 2020

Introduction No app is ever complete and you’ll never get to the point where users stop asking for new features. Sometimes those feature are low priorities so you’ll never get to them or they’re inane and you’ll never touch the idea with a 10 foot pole. This happened to... Continue reading

String List in C

Posted on April 22, 2020

Introduction Currently we have a generic list container which uses void pointers to allow anything to be stored. Previously, we created a type safe string hashtable wrapping the generic hashtable. We want to do the same thing for our list and so now we’re going to... Continue reading

Generic List in C

Posted on April 9, 2020

Introduction Lists (dynamic arrays) are yet another super useful data structure that C just doesn’t have. C arrays are great for when you can get away with a fixed size but not so fun if you need to dynamically expand because you don’t know quite how many elements you’ll... Continue reading

String Hashtable in C

Posted on March 28, 2020

Introduction We have this amazing generic hashtable and we can put pretty much anything we want into it, but it has a few flaws. It uses void pointers and has a pretty verbose setup with that callback struct. If you’re using the same types over and... Continue reading

Generic Hashtable in C

Posted on March 6, 2020

Introduction So, C doesn’t have a native hashtable object but that’s not a problem because we can use one one someone else wrote. Lack of a robust standard library is probably the biggest impoundments of working with C. It’s a real shame C doesn’t natively support hashtables because they... Continue reading

Formatting Strings for Logging

Posted on February 19, 2020

Introduction I’ve been working on a project, and I needed to add logging to the app. I wanted a log formatting function that can take a prefix and a format string (think a sprintf-type format string but safer). This function needs to be more than just an... Continue reading

Validating Constant Time String Comparison In C

Posted on January 20, 2020

Introduction Awhile back I wrote a constant time string comparison function. I briefly mentioned how the compiler can optimize away some of what makes the function constant time. Specifically, the k++ counter used to balance the increment when the forward scan of s2 stops.... Continue reading
