100 Days of Code 2026 – Postmortem

Posted In: 100 Days of Code

I finished 100 Days of Code again, hooray!!

I kind of did 100 Days of Code again on a whim. A new years resolution to do it sometime this year. So I decided why not and started on New Years day. I don’t think I left enough time in-between runs (only 2-3 months) and I was burnt out on it by the second half. 

Exercism exercises were supposed to be a daily thing to keep the github green when I wasn’t checking in code for anything else. Instead it kind of took over the whole thing. I was way too focused on finishing the Javascript track, and cleaning up old exercises that exercism broke. I am however glad that I defeated the dreaded Zebra puzzle and finished both the C# and JavaScript tracks. I almost want to finish the final 68 in the python track but I might be a bit burned out on exercism right now. When I recover, I might want to do the Typescript, and GO tracks too. Or maybe I should check out the leet code thing.

I am a bit dissapointed at myself for not making a proper gameboy game after going through that giant book. I couldn’t even make myself code pong or snake. That was supposed to be why I bought myself a chromatic after all.

Despite all of the version 3 documentation/online example problems I ended up liking the Vue library quite a bit.

I feel bad that the Food Logger with a Angular front-end/Go backend project kind of sputtered out and died when I got sick (I still have lots of gunk in my lungs). It would have made a nice resume project too. I do want to learn more GO. I bought the Writing An Interpreter In GO book, but not knowing GO very well was making it harder to understand.

Ollama was kind of fun, but I should really research how the vibe-coders are actually generating code and try to work that into a side-project at some point. If I ever redo my “home-lab” (which is a single raspberry Pi 3 right now), I think I would like to have Ollama on it to kind of act like a search engine/wiki of sorts. I wanted to do some image generation on it but it doesn’t look like that is ready yet, and I probably don’t have a good enough/correct graphics card anyway.

Revisiting the pico with the oled screen was fun. I was thinking I should make something like a single game gameboy with it (maybe the dinosaur game or doodle jump since the screen is oddly sized). Or it could be a status display on the new home lab if I ever do that. I did leave it running beside me in clock mode for a few days just for fun. I would still like to make a simon game with the pico too.

I wish I would have revisited my Basic interpreter to make it compile to a virtual machine or hook it up to LLVM and make a real compiler with it. Even just adding graphics would have been nice.

Lazydevs Academy did a follow up to the zelda top down movement code and made a program to walk around the overword of the first Pokemon game. I would like to revisit my code and do that. It would be nice to port that to the gameboy too.

I wimped out on too many days. There were too many times I almost called it failed.

Final Thoughts:

I am kind of two minds with 100 days of code. I do like that I actually get things done. However, it kind of takes over every spare moment of free time I have. I want to have a nice project each year/quarter. I just never seem to even get started if I don’t have a framework like 100 days of code to motivate me. Unfortunately 100 days of code also stops me from working on anything else.   Every time I say I am going to be more casual about it but I never am.

Many years ago, I used to participate in Ludum Dare to motivate me to actually make something. It was cool but 48 hours is way too short. I don’t have the time or strength to do things in marathon sprints anymore. However, the longer week+ length of things like the OLC Code Jam are still up my alley. I could join a jam most any time at https://itch.io/jams, but most of them are run by weirdos or are thinly disguised marketing.

I think I would really like something that is much longer than a Ludum Dare Jam, but also much shorter than a 100 Days of Code marathon. I think I need a way to start a project and finish it but in moderation. Not dropping or never starting it, but not letting it overwhelm everything too. I also want the things I work on to be something I care about. Following along with a coding book is still cool too. I’ll have to ruminate on that for a while. Maybe I just need to get a big calendar, hang it on my wall, and start plotting out projects and milestones.

Advent of Code Day 09

Another day another Advent of Code visualization. This time we are filling in patterns on a tiled floor and seeing which two red tiles make rectangles with the largest area. For part two you need to fill the loop made on the floor and make sure the rectangles are only those contained within the filled area.

It took me a looong time to figure this one out. I wanted to do a flood fill but that exceeded memory. So I only took the rows and columns where there was a red square. Then I flood filled that. (I tried figuring it out with horizontal and vertical spans but got nowhere.) Anyway I had some debug output that looked nice so I decided to make an image out of it. A visualization if you will. It is only at this point I realize my visualization is hugely distorted by clipping out the unused columns and rows. Probably would look cooler otherwise. Still it is kind of cool so you get a post with a picture of it

Since I had a C# console app it didn’t want me to let me make the image (System.Drawing didn’t have the Bitmap class probably need some sort of library added). Instead I did it in Python. Looks like I am a bit rusty, but I got there in the end. If you look at the far right of the diamond shape there is a spot that didn’t flood fill correctly. I guess that didn’t affect the final outcome.

Looking at the subreddit, if you don’t exclude the unused columns/rows the output is circular, pac-man like.

Advent of Code Day 08

I dropped off on Exercism.org once I got to the Zebra puzzle. I can’t get it working. I hope to give it another go soon.

I have however been participating in Advent of Code. Only 12 days this year. It was a lot so I am ok with that, but I do think that without a global leaderboard it is missing something. Even if people did ruin the global leaderboard with their “enthusiasm”.

I like all the visualizations you can see on the reddit page. So I decided to try my hand at one this year. Today we were trying to connect extension cords between pairs of closest junction boxes. On part two they want it connected so that is is one single big circuit. That is what I visualized.

Extension cord mesh

That’s a lot of extension cords and junction boxes. I made my code spit out a wavefront obj file so I could open it in blender. Unfortunately I don’t know enough Blender to render it well, so you just get a screen grab.

Anyway I thought that was fun. Looks like I should have used Kruskal’s algorithm.

I got another badge – Persistent Perfectionist

I remember looking at this one many times, and saying to myself, haven’t I done 20 iterations yet? I feel like I should have got this one by now. Well, today I finally did get to 20. I think it was a dumb test that did it too. The test was checking how random my random BigIntegers were for DiffieHellman. Apparently they weren’t random enough. I took off the bit of code that tried to clear the highest bit so the number wasn’t negative, and that did the trick to get it to pass.

It looks like there is a BigFloat class in C# too. I wonder if I could do a deep Mandelbrot zoom with that.

Seventeen exercises left until I am done with the C# track. I think I am going to be stuck on the Zebra puzzle for quite some time.

I got a new badge – Object-Oriented October

During my 2025 run of 100 Days of Code, I was using exercism.org as a fallback if I didn’t have a project idea/ as a warmup exercise / keep the github green when I wasn’t ready to check things in yet. Well I decided to keep at it until I finished the C# track (probably sometime in November at this rate). Anyway I got a new badge today and wanted to share. Here it is Object-Oriented October. The exercise wasn’t really object-oriented the but the language C# is.

PS. I have 29 left at the moment, I am at 146/175 exercises.
