After 5 years of daily workouts, I realized that streaks can hurt our progress. It's easy to give too much importance to them, and it feels that all the progress is gone when we break them Tracking the total days since I started keeps a healthier perspective on my habits. #buildinpublic

Part 2: Our self improvement journey has to be gratifying even when we fail. Self compassion isn't soft, it's strategic #buildinpublic #selfimprovement #mindset #selflove

When we slip up, using circumstances as excuses protects us from feeling bad, but it keeps us away from progress. One day someone asked me "If you had to catch a flight, would you use that excuse?". It was game changer #selfimprovement #buildinpublic #mindset

After a lot of resistance, I decided to post my first TikTok video Realized I was avoiding it because it felt uncomfortable, but that's exactly why I needed to do it. Growth happens outside the comfort zone. Good things can only happen if we put ourselves out there. #buildinpublic

Lately I've been working on "invisible" stuff for Uni Feedback: - Built a whole admin dashboard to make it easier for me to maintain courses and feedback - Built new scrapers get course bibliography, assessment and description But it was finally time to make UI improvements. Roast my design!

Last week I attended an indie builders co-working day in London. It's called @hackaditch, and it's just amazing! Today we made something similar in Lisbon and it was awesome! We had a productive day, got good feedback and made new connections! #coworking #lisbon #indie

Just published my first python package: yacli_menu. A few years ago I had to create some python CLI menus. Didn't like what was out there at the time, so decided to build my own :) Hope it helps someone! github.com/afonsocrg/ya... #python

$Example usage of yacli_menu ``` from yacli_menu import command, run_menu @command("Add Numbers") def add(): a = float(input("Enter first number: ")) b = float(input("Enter second number: ")) print(f"Result: {a + b}") return True @command("Subtract Numbers") def subtract(): a = float(input("Enter first number: ")) b = float(input("Enter second number: ")) print(f"Result: {a - b}") return True @command("Multiply Numbers") def multiply(): a = float(input("Enter first number: ")) b = float(input("Enter second number: ")) print(f"Result: {a * b}") return True if __name__ == "__main__": run_menu() ```$ Example output of a yacli_menu program:

```
$ python3 example.py
1. Add Numbers
2. Subtract Numbers
3. Multiply Numbers
0. Exit
Enter choice:
Enter choice: 6
Invalid choice. Try again.
Enter choice: asdf

Enter choice: 1
Enter first number: 19
Enter second number: 23
Result: 42.0
1. Add Numbers
2. Subtract Numbers
3. Multiply Numbers
0. Exit
Enter choice: 0
Exiting..

Screen sharing is the digital version of looking over someone's shoulder. How often do we end up asking others to scroll down, or to click somewhere? I believe the internet needs to evolve towards collaboration by default. Thoughts on this? 🤔 #webdev #ux dev.to/afonsocrg/st...

AoC 2024 - Day 25 "Code Chronicle" - ⭐️⭐️ Yey, it's done! To reduce search, I stored the locks in a tree of HashMaps, indexed by pin size. Thanks @was.tl and team for these challenges, it's been a fun journey!! Merry Christmas to everyone Code: github.com/afonsocrg/AoC #AdventOfCode #rust

AoC 2024 - Day 24 "Crossed Wires" - ⭐️⭐️ For Part 2, I checked which gates broke addition circuit rules: XOR outputs must feed into AND+XOR gates, and so on... Got a messy code, but found the 8 swapped wires! Code: github.com/afonsocrg/AoC #AdventOfCode #rust

AoC 2024 - Day 23 "LAN Party" - ⭐️⭐️ Got a fast solution by checking for complete subgraphs (TIL they're also known as cliques) while processing each edge. Used HashMaps and HashSets for faster lookup and intersections. Code: github.com/afonsocrg/AoC #AdventOfCode #rust

060

afonsocrg @afonsocrg.bsky.social · 22/12/2024

AoC 2024 - Day 22 "Monkey Market" - ⭐️⭐️ Used bit-wise operators to make the next number generation faster. For Part 2, stored diff sequences as 20 bit integers for faster lookup. Times: Part 1: 11.6ms Part 2: 147.8ms Code: github.com/afonsocrg/AoC #AdventOfCode #rust

afonsocrg @afonsocrg.bsky.social · 22/12/2024

AoC 2024 - Day 21 "Keypad Conundrum" - ⭐️⭐️ Defined the problem recursively and used caching to avoid re-computation of intermediate results. This one was a real conundrum. Happy with my execution times: Code: github.com/afonsocrg/AoC #AdventOfCode #rust

020

afonsocrg @afonsocrg.bsky.social · 20/12/2024

AoC 2024 - Day 20 "Race Condition" - ⭐️⭐️ Got a O(n) solution by storing the distance from each position to the end, and by checking for shortcuts in each position vicinity. Did a "diamond" for-loop for the first time, it was fun. Code: github.com/afonsocrg/AoC #AdventOfCode #rust

afonsocrg @afonsocrg.bsky.social · 19/12/2024

AoC 2024 - Day 19 "Linen Layout" - ⭐️⭐️ Memoization did the trick for this problem!! Also, instead of checking one pattern at a time, I checked if prefixes with different lengths existed in the pattern set, which sped up my solution by 4x. Code: github.com/afonsocrg/AoC #AdventOfCode #rust

AoC 2024 - Day 16 "Reindeer Maze" - ⭐️⭐️ Tough one. A simple A* search was not enough: Pre-computed heuristics by running a Dijkstra's from the final position, which made a HUGE difference. Also skipped searching states that only had one neighbor Code: github.com/afonsocrg/AoC #AdventOfCode #rust

AoC 2024 - Day 15 "Warehouse Woes" - ⭐️⭐️ Loved using recursion in this one. And feeling super stoked to get it working right in the first try!! Also, made some fancy looking match expressions for the first time. Loving Rust so far 🦀 Code: github.com/afonsocrg/AoC #AdventOfCode #rust

AoC 2024 - Day 14 "Restroom Redoubt" - ⭐️⭐️ Used the modulo operator instead of doing the whole simulation to get a solution for P1 in 28.6µs. For P2, checked the first state with no overlap and there I found the Xmas tree! Code: github.com/afonsocrg/AoC #AdventOfCode #rust

AoC 2024 - Day 12 "Garden Groups" - ⭐️⭐️ Used recursion to get area and perimeter. To find all sides I got all the edges in a HashSet, and removed the **adjacent** ones to count sides. The "E" example was very helpful! Code: github.com/afonsocrg/AoC #AdventOfCode #rust
