I wish that, after applying the PACER method from Dr Justin Sung, I could learn from this book with more discipline. August 13th, 2026 First session Topic: Sets and Functions What I learnt: Definition of a set and a function Sets of numbers: natural, integer, non-negative integer, rational, real, and complex Definition of an empty set, cardinality, subset, and proper subset Set builder notation Operation on sets Domain and range Insight: https://kafkuy.tech/reviews/interaksi/ Sun, 09 Aug 2026 15:05:00 +0700 https://kafkuy.tech/reviews/interaksi/ Di antara semua lagu-lagu Tulus, maybe ini yang paling sakit. Aku sangat mengagumi pemilihan kata-kata dalam lirik lagu ini yang semuanya dirakit dengan sangat indah dari awal sampai akhir. Terkhusus di ending lagu, aku melihat bagaimana Tulus menyimpulkan bagaimana kondisi orang yang ikhlas atau rela. Ia mengatakan bagaimana orang yang sudah ikhlas menyadari bahwa orang yang kita sayangi itu memang bukan untuk kita dan kita rela ia pergi, tapi tetap ada rasa di lubuk hati yang paling dalam agar orang yang kita sayangi itu mendekat. https://kafkuy.tech/reviews/placeholder-book-review/ Sun, 09 Aug 2026 14:59:00 +0700 https://kafkuy.tech/reviews/placeholder-book-review/ Overall, bagus untuk dibaca ringan sebagai teman duduk. Hanya saja ada kiat-kiat yang ada di sini yang seperti terlalu dipaksakan, dan kurang membantu untuk mengatasi overthinking. Sebagai orang yang lebih menyukai narasi self-help yang bentuknya praktis, buku ini tidak cocok buatku. https://kafkuy.tech/lab-notebook/data-structures-and-algorithms-learning-log/ Tue, 04 Aug 2026 14:46:00 +0700 https://kafkuy.tech/lab-notebook/data-structures-and-algorithms-learning-log/ Study Artefacts Excalidraw mindmap: https://excalidraw.com/#json=9peyf5js5-kSwihdWQWRR,iTcxPnsLYjl0Gh5cGyulMw Overview This month, August 2026, I intend to relearn Data Structures and Algorithms from the Grokking Algorithms book. This is mainly because I want to practice my problem-solving abilities and find new hobbies by solving LeetCode problems xD. August 1st, Saturday I read Chapter 1, “Introduction to Algorithms,” and Chapter 2, “Selection Sort.” I finished the first chapter quite late since I had to re-learn logarithms first on Khan Academy based on the book’s recommendation. https://kafkuy.tech/projects/fake-image-detection/ Sun, 02 Aug 2026 10:00:00 +0700 https://kafkuy.tech/projects/fake-image-detection/ Published as “Implementation of ResNet Architecture for Classification of Real and Synthetic (AI-Generated) Digital Images” in ICoBITS (International Conference on Business, Information Technology, and Science). Authors: Panji Tri Wahyudi (Institut Teknologi dan Bisnis Asia Malang), Ida Wahyuni (Institut Teknologi dan Bisnis Asia Malang), Khalilullah Al Faath (Universitas Gadjah Mada) DOI: 10.32664/icobits.v1.58 Abstract The development of Artificial Intelligence (AI) enables the creation of realistic synthetic images, often referred to as deepfakes, which are increasingly difficult to distinguish from genuine photos. https://kafkuy.tech/reviews/shape-of-my-heart/ Sun, 02 Aug 2026 02:20:00 +0700 https://kafkuy.tech/reviews/shape-of-my-heart/ Ini lagu, jujur … Mau dibilang lagu butterfly era, bukan. Mau dibilang lagu galau juga bukan. Menurutku lagu ini lebih ke penyesalan dan berusaha untuk berubah sih. Saat ini full on-repeat. Reff-nya enak untuk diulang https://kafkuy.tech/posts/senior-high-schools-era/ Sun, 02 Aug 2026 01:22:00 +0700 https://kafkuy.tech/posts/senior-high-schools-era/ Watching Kafka Bintang Timora’s SHS-era VTs made me wonder what I was doing during my own high school years. Kafka managed to join so many extracurricular activities, while I only joined Rohis and the Biology club. Looking back, I barely remember any memories from those years beyond sitting in class and studying. If my future children ever read this, I hope you don’t make the same mistake I did. There’s nothing quite like the high school years, as they’re the most memorable parts of your adolescence. https://kafkuy.tech/lab-notebook/thalassemia-capture-app-dev-log/ Mon, 27 Jul 2026 09:00:00 +0700 https://kafkuy.tech/lab-notebook/thalassemia-capture-app-dev-log/ Project: Thalassemia Capture App (Flask + OpenCV, MiiCam USB microscope camera) Period: ~July 27 – August 4, 2026 Working directory: thalassemia-capture-app/ (working copy) — synced to the thesis documentation mirror Part of the Thalassemia Edge Deep Learning Model project — this log covers the image acquisition app specifically.

You can squash multiple commits into one before pushing! git rebase -i HEAD~3 Then mark commits as squash or fixup. Makes PR history much cleaner.

He asked me this because he knew my childhood dream was to become a doctor. I wanted to laugh the moment he asked to hide my actual expression, but the first word that came out of my mouth was, “Yes, Mas.” He doesn’t know that this question still haunts me at night, when I’m alone, when I’m with my friends, while scrolling social media, and at completely random moments. https://kafkuy.tech/posts/merekalah-pemuda-al-kahfi/ Mon, 15 Sep 2025 19:47:00 +0700 https://kafkuy.tech/posts/merekalah-pemuda-al-kahfi/ Catatan Kajian: Merekalah Pemuda Al-Kahfi Syaikh Muhammad al-Hasyimi hafizhahullah Mantan pengajar Universitas Islam Madinah dan Universitas Ummul Qura Makkah Pendahuluan Surah al-Kahfi memuat empat kisah besar yang penuh ibrah (pelajaran): Kisah Ashabul Kahfi , menceritakan tentang ujian terhadap agama, Kisah Pemilik Dua Kebun, menceritakan tentang ujian terhadap harta, Kisah Nabi Musa dan Khidr, menceritakan tentang ujian terhadap ilmu. Kisah Raja Dzulqarnain, menceritakan tentang ujian terhadap kekuasaan. Fitnah agama disebut pertama dalam surah ini karena ia adalah fitnah (ujian) yang terbesar. https://kafkuy.tech/posts/fake-images-detection-a-lab-report/ Sat, 09 Aug 2025 19:52:00 +0800 https://kafkuy.tech/posts/fake-images-detection-a-lab-report/ This fake image detection research is a collaborative effort between me and my online friend, Panji. He approached me on July 29th, 2025, explaining that he wanted to collaborate on doing research in Computer Vision, particularly Fake Image detection. At first, I almost said no since I had never heard or read a single paper on the topic, and I wanted to focus on preparing my materials for my master’s. But then I thought, why not challenge myself with something completely new? https://kafkuy.tech/posts/khalil-lab-report-2-implementing-a-search-feature-using-google-search-on-a-hugo-website/ Tue, 29 Jul 2025 02:56:00 +0800 https://kafkuy.tech/posts/khalil-lab-report-2-implementing-a-search-feature-using-google-search-on-a-hugo-website/ Overview This lab documents the step-by-step process of adding a client-side search functionality to a Hugo-powered static site using Pagefind, a privacy-focused, JavaScript-based search library. Before choosing Pagefind as my tool for this search feature, I found this article on Hugo’s official docs. The official documentation for Pagefind has already done a great job of writing the tutorial; however, since there’s no specific tutorial for Hugo, I thought I might try writing one. https://kafkuy.tech/journals/schedules/schedules/ Mon, 21 Jul 2025 00:00:00 +0000 https://kafkuy.tech/journals/schedules/schedules/ This Week To-dos Fix the single page’s layout https://kafkuy.tech/posts/meditation/ Sat, 19 Jul 2025 01:07:00 +0800 https://kafkuy.tech/posts/meditation/ Book 1 This book records the virtues I have inherited from those who came before I am, from what I heard and told, and those whom I have lived beside, from what I experienced and learnt, and also those whom I have never met, whose works nonetheless have shaped the person I am. From my mother: I learnt discipline, patience, and hard work; to have always put my education first, and be grateful, whatever the result is, good or bad; She rarely displays affection in the way others might expect. https://kafkuy.tech/posts/introduction/ Fri, 18 Jul 2025 13:26:00 +0800 https://kafkuy.tech/posts/introduction/ Hi! This is me Khalil. Even though this isn’t actually my first post in this website, I would like to say thanks to everyone who visits this website.
