Nearly every programming language has some flavor of "structure" declaration, where the programmer can conjure a new type representing the composition of other primitive types or structures, neatly organized into named fields.

Packed lunches are a great way to save money, but being limited to foods palatable at room temperature (or colder) can be a little discouraging.

Spaced repetition is an effective habit for memorizing small fragments of information for, effectively, an indefinite amount of time.

This blog post is about a GNU/Linux rabbit hole I fell down in the belief I was chasing a mighty adventure.

I started working on my master's degree last September.

When I started writing this article, I didn't mean to do anything more than describe a comment system I'd written in Guile.

For the past ten months, I've been using my PinePhone as a "daily driver."

My Flipper Zero arrived in the mail a few weeks ago, ending a nearly two-year wait for its arrival.

Last night – Thursday, May 12th, 2022, at 22:17L – my cat was put to rest.

It's that time of year again where I take some time to reflect on UMass CTF.

The background for this project is a lesson in avoiding dishonest vendors.

This was the first year our capture-the-flag event, UMass CTF 2021, was open to the public.

Well, this is certainly overdue.

This is a post I've been meaning to write for a while now: one anecdotally comparing programming languages in the Lisp family.

It's typical for the younger sibling to look up to and mimic the older sibling, which is apparently what happened while I was away at school.

If you're about my age and had a similarly dull upbringing, you probably also have memories of playing video games behind a teacher's back whenever class involved going to some sort of "computer lab."

It's been over a year since I last wrote about contenders for the throne that C currently sits upon, so I'll spare you the prosy introduction and cut to the chase.

This is the fourth and final set of for my self-imposed challenge of completing at least fifty of the exercises on Dennis Yurichev's challenges.re by the end of the year.

This is the third set of solutions for my self-imposed challenge of completing at least fifty of the exercises on Dennis Yurichev's challenges.re by the end of the year.

Hey, there!

This is the second set of solutions for my self-imposed challenge of completing at least fifty of the exercises on Dennis Yurichev's challenges.re by the end of the year.

Rather than study for finals this week, I spent my time moving this blog over to Haunt.

My long-lived hiatus from capture-the-flag has come to an end, as I got off my ass this weekend to play in PlaidCTF 2019.

As mentioned in the (now deleted) post I wrote describing my plans for 2019, one of my goals this year is to get through at least 50 of the exercises on Dennis Yurichev's challenges.re.

In the introduction of the previous post I wrote for this series, First Impressions of the Rust Programming Language, I alluded to the presence of arguments that programming language safety should be achieved by moving to languages such as Java which run…

Slime the World was my entry to this year's Autumn Lisp Game Jam, and it managed to win second place.

Recently, I read Michael Nielsen's essay, "Augmenting Cognition".

C is almost 50 years old, and C++ is almost 40 years old.

It seems that the general consensus on "distro hopping," the act of constantly switching between distributions of GNU/Linux, is that it's a bad habit that should be consciously avoided.

My capture-the-flag team played in the Insomni'hack teaser this year.

My first experiences with Duke Nukem 3D were with EDuke32 ages ago.

TL;DR, I discovered a stack-smashing vulnerability in GZDoom's interpreter for ACS.

"funsignals" was a 250 point binary exploitation challenge with 58 solves.

At a first glance, it might seem that game cheats like AimTux are something that could only be conjured by the most talented of reverse engineers.

It seems that static linking is back in style, or at least popular among all the hip new programming languages of today.

To start off, I'd like to say that I know very little about audio programming and digital audio in general.

Hey, this is a very brief tutorial on scanmem, a memory manipulation tool for Linux that’s well suited to game hacking.

About two months have passed since the first release of Nekopack - a tool I wrote for extracting game data from Nekopara's XP3 archives.

SDL2 is my favorite graphics library right now.
