Reckoning Day

Today is a day of reckoning, where I come to terms with both what I have achieved, and what I haven’t over the course of this challenge. I’ve made significant progress by staying consistent over the last couple months, but I have definitely missed some milestones that I wanted to hit. Evidenced entirely by the project table above. I knew that I was being ambitious, but I let some things go that I certainly thought that I would have complete by now.

CodinGame - There Is No Spoon (Episode 1) - Continued

Yesterday’s code only solved the most basic test case. It is time to generalize the solution to pass all test cases. The primary issue is that my solution only checks the grid for nodes that are immediately to the right and down from the visited node. If there are any non-node grid-points in-between nodes, those points need to be skipped. I feel like I’m explaining it badly. Essentially, we need to keep checking the row and column until either we reach a node, or the edge of the grid.

60 Days of Code

It has been 60 days since I have started this challenge. Things have gone pretty well, and I’ve gotten a lot done by forcing myself to stick with coding something everyday. Even if some of the changes are quite small, the point of the challenge has worked. Stay consistent. Learn new things. There is still a lot of do. At least 205 days worth of work to go.

Code Conventions and Style

While working on the new IP library for IP Protocol From Scratch (opens in a new tab), I started to need to include header files from source code that I wrote, rather than only the standard libraries. I did some research on modern conventions, and came across this StackExchange post (opens in a new tab). To summarize the modern ordering for include:

Ambiguities in RFC Language

While reimplementing my ICMP code for IP Protocol From Scratch (opens in a new tab), I spent some time (re)reading RFC 792 (opens in a new tab) for ICMP. I came across some interesting language used in the Echo or Echo Reply Message section.

IP (6) Protocol From Scratch

I got back to the network code programming today, with a refactoring of my V1 and V2 code from IP Protocol From Scratch (opens in a new tab). In V3, I’m separating the logic into proper header files, and building up a library that is more generalized. I’m also performing my first implementation of IPv6 (opens in a new tab). At first I was thrown off because the first 4 bytes of the IPv6 header did not align with uint8 or uint16, before I realized that a 32-bit member would perfectly capture the first fields of the header: uint32_t version_class_flow;. The IP Version takes the first 4 bits, the Traffic Class takes the middle 8 bits, and the Flow Label takes the last 20 bits. With my experience in packing and shifting bits around in the first two versions, this shouldn’t be too bad.

Network Protocols Version 2

Further refinements to version 2 of IP Protocol From Scratch (opens in a new tab). I have refined all the functions up to socket programming. It is still far from a perfect application, but it is getting there slowly. Some of the values are still hardcoded, such as source and destination addresses, but the structure is being put into place to make this a dynamic application. I think the goal at this time is to have a minimal ping-style application. Once I am able to run the program from the command line with custom arguments for source and destination addresses, number of pings, and variable payload sizes… I think I’ll consider this project complete. One of the most significant parts to build will be handling fragmentation. That I’m reserving for last.

Network Protocols Version 2

With the introductory network programming completed, and a packet successfully built and sent out of the local interface, it is time to clean up the program, and expand the functionality a bit. I’m still sticking with simple ICMP packets, but refactoring the code to be a bit more dynamic. Pulling functionality into functions, setting up boundaries and defensive programming for data, using smarter placement of assert, more useful enum values, and defining some magic numbers. The goal now is to get a bit closer to ping functionality. Sending an arbitrary number of packets to another host on the wire, and processing the responses.

Bug Fix - zshrc

I ran into an issue with my zshrc file today. Once again, related to the ssh agent. I use Linux Mint Debian Edition (opens in a new tab) with the Cinnamon DE. In an effort to be “helpful,” Cinnamon launches an SSH Agent for you when you boot up. This conflicted with my script, as my script was overriding the $SSH_AUTH_SOCK with a stale agent. The fix was relatively simple, just check if the $SSH_AUTH_SOCK has already been set.

Network Protocols - Calculating the IP Header Checksum

I’m working through the checksum calculation today. I’ve read up on RFC 1071, RFC 1141 and RFC 1624, which all have to do with implementing checksum calculations for the Internet Protocol. The process seems relatively simple, but I needed some refreshment on terminology since I’m not well versed in binary math and manipulation.

Project Euler… Thoughts on AI

I came back to Project Euler today, to complete the work on p25. It was about a week ago that I had ChatGPT generate a BigInt library for me to calculate extremely large numbers. I was able to one shot the package with ChatGPT, and the library and testing code worked fine with numbers that had 1000+ digits. It was a cool exercise, where I learned absolutely nothing. Furthermore, I came back to the problem today to try and use this new library to solve the Euler problem, and the code is useless. Not only do I have no true understanding of how the library works, but I can’t iterate on it without reaching back out to AI for help.

Another Project - HTTP Status Code Reader in C

I was curious about sockets in C, and parsing HTTP responses, so I had ChatGPT whip me up a POC to read the status code from a website. I still wrote this all out by hand, to work on the muscle memory and work through each function individually.

I took some of the Laravel lessons from yesterday, and applied them to another project I’m working on for a client. I also got that project pushed up to Github into a private repository. It is definitely helpful to take the lessons from a tutorial and immediately apply them to other projects. I need to remember this when it comes to working on learning the other languages, such as Go, Rust and Haskell.

365 Days of Code - Day 023

Thu, 12 Feb 2026 00:00:01 -0500

Day 23 has begun, and it is technically nearly over. I had a busy day today, for everything other than code. This was bound to happen eventually. But, to keep the dream alive, I’m not ending this day without working on something. To make it easy on myself, I’m going to work on this website some more. Incremental improvements is how things get done. The only real change made today was to move the header tag from the partial page into the base layout. Now it matches the other sections.

I finished up Problem 20 (opens in a new tab) this morning. I went well beyond what was needed to find the solution, but this is all just practice. I tried to be as defensive as possible, validate everything, and provide options for alternative numbers. The program can run for factorial values well beyond 100!. Although, the program gets quite slow once you are into the really large factorials.

365 Days of Code - Day 021

Tue, 10 Feb 2026 00:00:01 -0500

3 straight weeks of “code,” or at least “code-adjacent” work. Longest streak yet. I feel a bit like Sam in Lord of the Rings (opens in a new tab).

This is it. If I take one more step, it’ll be the farthest way from home I’ve ever been.

So, what do we work on today? There is a plethora of opportunity. Let’s start by recapping some of what I have done (or started) so far:

365 Days of Code - Day 019

Sun, 08 Feb 2026 00:00:01 -0500

Software can be crazy. I’m having the same issue from yesterday from Ubuntu. The issue is that my site is not rendering with the Hugo development server. I started poking a bit more at the problem, and found that both Chrome and Firefox were both working fine, but Firefox Dev Edition would not render the site. Specifically, the css file request never finishes. I ended up resetting Firefox Dev, and it appears to be working again. I’m still not sure exactly what the issue was, but my best guess is some type of caching issue. I always develop with Disable Cache enabled, but clearly something went wrong while requesting information from the site.
