Day 17 of #AdventOfCode2024 kept me humble. Spent a couple of hours wrestling with Part 2, but no dice. Probably missed some tiny detail. I must have put a decimal point in the wrong place or something.

A scene from the movie Office Space showing two characters sitting in a car. The character on the left looks frustrated and says, "I ALWAYS DO THAT! I ALWAYS MESS UP SOME MUNDANE DETAIL!" The caption reflects a relatable moment of making small, frustrating errors.

Missed finishing Part Two for Day 12 and Day 15. Need to start earlier—or maybe tackle it the night before. Frustrating, but onward! 🦀
This image is an ASCII art display showing daily completion stats for Advent of Code challenges. The numbers "1" and "2" are represented as large, detailed ASCII art filled with decorative patterns like stars, wavy lines, dots, and characters such as @, ~, and #. To the right, the daily progress is listed in a column, with Days 1 through 15 marked by two yellow stars (**), indicating both parts of the challenge were completed. Days beyond 15 are visible but unmarked, suggesting no progress has been made yet. The combination of festive ASCII art and progress tracking creates a visually appealing summary of the user's Advent of Code achievements.

Day 11 - #AdventOfCode2024 #Rust
Part 1? Nailed it with a quick and dirty approach. Part 2? Let’s just say Google’s quantum chip wouldn’t have solved it before the universe ends. Buckled down, thought it through, and shipped the final solution: 99 lines of #rust, 78 without tests. 🦀💡
A terminal screenshot showing the execution of a Rust program for the Advent of Code Day 11 challenge. The program runs in release mode, processing input from a file named stones.txt. Two phases of the computation, labeled as "Cosmic Phase Phase 1" and "Cosmic Phase Phase 2," are completed with visual indicators (asterisks). The program finishes execution in 0.348 seconds, using 130% CPU. A subsequent tokei command outputs the code statistics: 1 Rust file with 105 lines, of which 99 are code, with no comments and 6 blank lines. The interface is styled with a vibrant purple background.

🎅🏽 Surprise bonus post — pic of mah boy straight up chillin’. He asked me to take this selfie for him on account of he got no thumbs. 👎🏽 #carrotcake
A relaxed orange tabby cat lies sprawled across a wooden shelf inside a boat cabin, with one paw hanging over the edge. The cat looks directly at the camera with a calm and slightly curious expression. In the background, various items like a pink bag, headphones, and yellow-lidded containers are visible, giving a cozy and lived-in vibe.

Day 7 - Advent of Code 2024 #AdventOfCode #rust
Taking a break from Day 8 to post Day 7. Optimized using perf, criterion & heaptrack till I tired of it. They're getting more fun to think through! Code runs fast; could be cleaner but, meh...you get what you pay for. 🤷🏽

A terminal window showing output from Roland's Rust-based Advent of Code Day 7 solution.. The output includes several stages of analysis with emojis and decorative formatting. It shows 'Phase 1: Basic Structural Analysis' and 'Phase 2: Advanced Structural Analysis', with both stress coefficients marked as 'REDACTED'. The output includes playful references to elephants and jungle safety, ending with a notice that the bridge should be safe to cross 'until the elephants return'. At the bottom is a command line showing the program was run with the --redact flag and completed in 0.05s.

Herons in Seattle, herons in Mexico — turns out we share the same migration route.
A tall gray heron stands on a dock near the edge of calm water, holding a fish in its long, pointed beak. The fish is dark and partially hanging out of the heron’s mouth. The background includes a wooden dock and rippling reflections in the water.

Day 6 - Advent of Code 2024 #AdventOfCode #rust
Solution evolution:
>6s runtime 🐢 - Vec/HashSet => poor cache & full-sized data types
0.65s 🐇 - Parallel with Rayon => still memory heavy
0.071s 🚀 - Bit-packing, small ints, better locality + parallel ~100x faster 🦀

A terminal screenshot shows the output of running Roland's Rust program solution to the Advent of Code Day six challenge with input redaction. The output includes lines stating “Temporal Analysis Complete!” and “Guard’s Patrol Coverage: *****,” followed by “Paradox Analysis Complete!” and “Viable Paradox Points: *****,” and ends with “Time Stream Analysis Concluded.” The timing summary at the bottom shows user, system, CPU usage, and total run time.

Day 5 - Advent of Code 2024 #AdventOfCode After yesterday's trickery, today's puzzle felt suspiciously straightforward. I can't help but feel we're being set up for something... Day 5 and already playing mind games!

A terminal window showing the output of a Rust program run with time and redact flags. The program outputs 'Ancient Printer Diagnosis Complete!' followed by two redacted values shown as asterisks (*****) for 'Properly Ordered Updates Sum' and 'Reordered Updates Sum'. The command execution time is shown as 0.05s user 0.01s system with 99% CPU usage.

Day 4 - Advent of Code 2024 #AdventOfCode #rustlang
Fooled me twice, so I got spiteful and SIMD'd tf outta this, sprinkled in a little unsafe, then squeezed as much juice from it till I got bored. Final time stats: 20k file -
0.04s user 0.00s system 99% cpu 0.043s total.

A terminal screenshot showing the result of running a Rust program to analyze a text file named "part_one.input". The program reports that it found the word "XMAS" a redacted number of times and identified a redacted number of cross patterns involving "X-MAS". Below this, the timing results show: 0.04 seconds user time, 0.00 seconds system time, and 9% CPU usage, with a total runtime of 0.041 seconds.

Gratuitous PennyPi pic.
A white cat with green eyes and brown markings on its head rests its head and paw on a textured, circular cat bed. The cat appears relaxed, gazing softly toward the camera. The foreground reflects the surface of a polished dark wooden table.

Day 3 - Advent of Code 2024 #AdventOfCode #rust_lang
Today's challenge offered an opportunity to showcase Rust's zero-cost abstractions: built a heap-allocation-free solution using only std traits and newtype pattern. Type-safe, clean lifetimes, no external crates needed.

Terminal output showing the execution of a 'cargo run' command with Christmas-themed formatting. The output reads: '> cargo run --release --quiet -- memory_dump.txt' followed by 'North Pole Memory Analysis Complete!' with Santa and Christmas tree emojis. Below that is 'Corrupted Memory Scan Results:' with a magnifying glass emoji, and 'Total Checksum: *********' with a star emoji. Each section is separated by equal signs as decorative dividers. The text appears to be displayed in a dark terminal with monospace font.

Day 2 - Count it! #AdventOfCode adventofcode.com/2024/day/2 #rustlang #programming
A terminal window showing the output of a Rust program analyzing reactor safety. The command 'cargo run --quiet -- part2.txt' is followed by a formatted output display with emoji. It shows 'Red-Nosed Reactor Safety Analysis Complete!' with a deer and Christmas tree emoji, followed by a section showing 'Total Reports Analyzed' and 'Safe Reports Detected' with asterisks masking the actual numbers. The output ends with 'Problem Dampener Active' with a wrench emoji. All text is enclosed in decorative equals-sign borders.

First year participating. Definitely fun! I over-engineered the solution nice and proper by using my concurrent
#rustlang framework. That'll likely be my signature move this entire event. 🚀🦀

Rust #devs often go straight to atomics when talking concurrency. Built this message-passing framework to make fast, safe, and concurrent code more approachable for newcomers. Check it out if that sounds useful! 🦀 #rustlang #rust
