Eleventh Grade in Review
Damn, what a year. Looking back at 11th grade, it's hard to believe all that happened and how much I accomplished. From the start, I knew it was going to be tough, but I had no idea how much I would learn and grow. The first day of school in July was nerve-wracking as usual. New classes, new teachers, new faces. I was super excited to dive into Mobile App Development but also a bit terrified. Pak Ilham turned out to be an amazing and chill teacher, though. He made even the most complex topics seem understandable. I also started participating in competitions this time around. By October, I had found my rhythm. I was ACING those Software Engineering classes. I spent countless hours practicing, learning new things in my room, and helping others through the tough spots. I even made it to the final stage of a web design competition—my first final experience. I was so damn nervous, but in the end, me and Gilang (shout out to my bro) managed to build several frontend projects, even though we didn’t win anything (🥲). I also finished my first Bromo trip with some friends. The end of October was challenging because I encountered a personal issue I'd never faced before, but I still managed to get over it and continue my 11th-grade journey. December brought a festive atmosphere to school. The Dies Natalis concert was a highlight—they invited Hal, an Indonesian singer, and other artists too. Finals were stressful because the exams didn’t go as expected, but I got through them with decent grades. The holiday break was perfect for recharging and spending time with family. Oh, January. The new year meant new resolutions. I promised myself to stay more organized and manage my time better. Easier said than done, right? But I did make some progress. I started using a planner religiously, which actually helped a lot. I started training for LKS too. February and March were incredibly busy. Between schoolwork, freelance projects, and preparing for LKS, I barely had time to breathe. My weekends were packed with study sessions and literally just coding. It was exhausting, but I knew it would all be worth it in the end. And here it is, February 24th, the LKS D-Day. It all went well until the final round when the judges asked me and Adit to prove my solution to the given problems in 5 minutes, and I completely panicked (since I’d never practiced for such situations). But thankfully, I won 1st place in the city-level LKS and got the opportunity to represent Malang in the prestigious LKS Jawa Timur in the field of AI. Between the end of March and the middle of April was LKS Jawa Timur. I came prepared and was kinda confident I’d bring home the trophy. But things went wrong on Day 1—our work wasn’t in the top 3 at all. Thankfully, Day 2 saved us (shoutout to Adit), and we managed to bag the trophy. May was the time to go back to school and leave my LKS training behind (since there’s no national-level for the AI field). But things started to wind down. The finals were not that hard, and I even found some time to hang out with friends and enjoy my time. June was a mix of emotions. On one hand, I was relieved that the school year was over. On the other hand, it was hard saying goodbye to my Sotel classmates. We went on a trip to a villa in Batu and enjoyed our time there. Looking back, 11th grade was a rollercoaster. There were highs and lows, but through it all, I learned a lot about myself. I became more resilient, found new passions, and strengthened my friendships. Now, I’m ready for the challenges and adventures that senior year will bring! (jk I'm scared as heck) ### !

2024 So Far...
## New Chapter is Here! Hey there! I'm diving back into the world of blogging, though my updates might be as rare as a blue moon. How's life treating you? Hopefully, it's been as kind to you as it has to me this past year. Bagged the prestigious LKS AI (both at the province and city levels), snagged a slick new pair of kicks—still eyeing that shiny new laptop, though. Crossing my fingers for my 11th-grade report card; fingers crossed it matches my expectations.  Been neck-deep in new projects lately, like revamping the OSIS Moklet Web-app to encompass all school organizations, not just the student council (also renaming it to Moklet.org). Also, whipped up the official website for LKBB Antareja, alongside a handful of freelance gigs. Oh, and I'm also competing in some competitions—Samsung Solve For Tomorrow (SSFT), a Web Programming showdown, with more on the horizon. Plus, I'm packing my bags, trading Banten for the greener pastures of West Java. But amidst all these events, I'm finding moments to breathe and appreciate the journey. Each project, each competition, each move feels like a step forward, a new chapter unfolding. And sure, it's a bit chaotic at times, juggling deadlines and dreams, but there's a thrill in the chaos, a sense of purpose driving it all forward.

2023: My Most Transformative Year
You know, like everybody else in this world, I've always planning some revolutionary things to do next year. But like everybody else in this world, I've never really done any revolutionary things in each year so.....  As we bid farewell to 2023 and step into the unknown corridors of 2024, it's only fitting to take a moment to reflect on the roller coaster ride that was the past year. For me, 2023 was a year of firsts, failures, friendships, and a whole lot of learning. Join me as I navigate through the highlights of my journey. One of the most significant milestones of 2023 was diving headfirst into the realm of entrepreneurship. So me and my buddy Beni decided to dip our toes into the whole entrepreneurship thing. Long story short, we started a project that actually brought in some cash. Not bad for a couple of rookies, huh? Learning became a constant companion throughout the year. From honing technical skills to exploring new areas of interest, 2023 was a chapter of intellectual growth for me. 2023 was like a crash course in everything. I'm talking about leveling up my skills, exploring random stuff, and basically turning myself into a mini expert in, like, 100 different things. Learning was the name of the game, and damn, it was a wild ride. The tapestry of life is woven with the threads of relationships, and 2023 introduced me to an array of new friends. Met some cool-ass people along the way. New friends, new vibes. Whether we clicked over some weird hobby or just shared a common hatred for Mondays, these connections added some serious flavor to my year. Decided my personal website needed a glow-up. Remade my personal website like I was on a mission. It's not just about looking good (although that's a bonus), but about showing off the real me—projects, wins(if I ever win anything), and the whole shebang. So, 2023, you crazy son of a gun. Thanks for the ups, the downs, and the messy in-betweens. Each curveball taught me something, and I'm heading into 2024 with some battle scars and a big ol' grin. Here's to more adventures, more growth, and less boring shit. Cheers to the next chapter! 🚀✌️ "2024 gon be our year fr" "Bismillah menang LKS"

Trithemius Cipher in Rust
Hey fellas! Ever heard of "Trithemius Cipher"? You might be wandering, what the heck is a trithemius? Well actually, Trithemius or known as Johannes Trithemius is a german polymath that created this cipher. The Trithemius Cipher is one of the polyalphabetic codes designed to be easier to use. Today, let's embark on a thrilling journey into the world of cryptography with Rust. Our destination? The Trithemius Cipher – a historic encryption technique that adds a dash of mystery to our codes. Our weapon of choice for this cryptographic escapade is Rust, a language known for its speed, safety, and expressiveness. Our code is a humble blend of I/O operations, string manipulation, and a pinch of modular arithmetic. First, you have to install [Rust](https://rust-lang.org/), Then, you create a new project with the cargo in whatever folder you desire. ```bash cargo new trithemius_cipher ``` Now that's done, you can copy (or type if you're not lazy enough) the code below: ```rust use std::io; fn trithemius_cipher(message: &str, shift: u8) -> String { let message_chars: Vec<char> = message.chars().collect(); let mut result: String = String::new(); for &c in message_chars.iter() { if c.is_alphabetic() { let base: u8 = if c.is_lowercase() { 'a' as u8 } else { 'A' as u8 }; let encrypted_char: char = ((((c as u8 - base) + shift) % 26) + base) as char; result.push(encrypted_char); } else { result.push(c); } } result } ``` Wowowowow, wait a second, what the heck was that just now? The Trithemius Cipher is a polyalphabetic substitution cipher, a mouthful that basically means each letter can be replaced by multiple different letters (it is as simple as that). In our Rust code, this is achieved through a clever combination of modular arithmetic and character manipulation. ```rust let base: u8 = if c.is_lowercase() { 'a' as u8 } else { 'A' as u8 }; let encrypted_char: char = ((((c as u8 - base) + shift) % 26) + base) as char; ``` Breaking it down, each alphabetic character takes a journey from its original position in the alphabet to a new destination based on the user-provided shift value. The modular arithmetic ensures that the journey wraps around the alphabet seamlessly. "But why Rust?" you may ask. Rust, with its emphasis on performance, memory safety, and zero-cost abstractions, proves to be an ideal companion in this case. The code gracefully handles user inputs, ensuring a smooth interaction with the cipher. Now to run the code, you'll have to do a bit of command-line interaction. Run this command in the root directory where the `Cargo.toml` are placed at ```bash cargo build ``` Now you just have to run the .exe file in the debug folder at the target folder ```bash .\target\debug\trithemius_cipher ``` That's it! Now you can encrypt a message with the Trithemius Cipher method. But hold on, how do you decrypt one? You just have to reverse the method. ```rust fn trithemius_decipher(message: &str, shift: u8) -> String { let message_chars: Vec<char> = message.chars().collect(); let mut result: String = String::new(); for &c in message_chars.iter() { if c.is_alphabetic() { let base: u8 = if c.is_lowercase() { 'a' as u8 } else { 'A' as u8 }; let decrypted_char: char = ((((c as u8 - base) + 26 - shift) % 26) + base) as char; result.push(decrypted_char); } else { result.push(c); } } result } ``` That's it! We're done, now you can use these methods on your code. Like for example here if you want to decrypt a greeting message to your friend (not sure why'd you do that tho), you can just make a main function and use the methods above: ```rust fn main() { let encrypted_message: String = trithemius_cipher("What's good buddy?", 3); println!("Encrypted message: {}", encrypted_message); } ```
