Both of my parents are artists, especially my mother, who has an incredible ability to draw and paint almost anything with remarkable realism in many media. Growing up surrounded by their work inspired my love for art, and I was known as a good sketcher as a child. Even then, I never came close to the level of skill my parents had. Although I dreamed of developing the same skills, I stopped…
I am tired of wasting money and time on self-development books. I am talking about a broader genre, whether it is about career and business, health and wellness, relationships, or communication. They fall into the same category that this post talks about: books that give advice directly to the reader. They are full of fillers and repetitive ideas Self-help books are trying to bring a few main…
I have never been able to focus on work with AI. Whenever I work with an AI agent, I always tend to multitask. Maybe this is part of the lowest spectrum of ADHD, a part of myself that I can’t avoid. It is not a pleasant feeling or experience to work with multiple agents. You can name a few best practices about how to work with AI. To some degree, they work.
These are my personal notes on the BlankOn Revival Project. Although many of the ideas discussed here have been seriously considered by the BlankOn Foundation team, they do not necessarily represent the official views of the organization. Many of these reflections emerged from discussions with several individuals, not all of whom are mentioned here. I would like to sincerely thank them for their…
A 5-minute lightning talk session is surprisingly difficult for me, so this blog post serves as a backup in case I can’t properly deliver what I want to say. Thank you for reading! Teman-teman, nama saya Piko. Saya lahir dan tumbuh di pulau Lombok, sebelahnya Bali. Latar Belakang Tahun 2015, saya pindah ke Jabodetabek. Setelah 1 tahun di sini, perasaan saya campur aduk. Di satu sisi saya senang…
I think the luckiest people are those who have people that care about them and know how to accept and appreciate that care properly. One of the shapes of caring is feedback, which sometimes is hard to swallow. Thus, delivering one requires specific skills just as important as receiving one. When someone has concern about their friend, coworker, or even their favorite barista’s latte art skills,…
Communities allow me to see the world in different perspectives. They are like bubbles, but each contains portions of other kinds of bubbles. People from different backgrounds come and go, bringing diverse goals, intentions, opinions, and politics. Yet, we gather for the same domain or shared interest. I grew up in communities. They filled the gaps left by my parents (who are still alive but were…
This is a now page. Last updated: June 2026. Work I’m currently working at Noctua Games as Head of Engineering, navigating the interesting intersection of game publishing, tech architecture & infrastructure, and building a team that ships things well. Communities I maintain and am active in two communities: BlankOn Linux (an Indonesian GNU/Linux distribution and its foundation) and Lombok…
I have write this guide in a Reddit thread but no one is interested until they saw the video. :D Notes A good prank is one that is light-hearted, harmless, and designed to amuse rather than to cause harm or distress. Please pick a suitable victim. Jumpscare could be dangerous for individuals with heart conditions or other health issues. In extreme cases, it could potentially trigger a cardiac…
The Rejection and Acceptance When I first heard about Louca 2023, I was very excited and immediately submit two abstracts. I was convinced that one my submissions is interesting enough to be accepted, except is was not. None of my submissions made it but I am in no doubt that the accepted topics that was listed in the Louca webiste were a lot more interesting. Then one month before the event, I…

The articles will be divided into 4 parts: Preparation Ideation Development Publish If you happen to attend my talk in UbuCon Asia 2023, then you may expect that I repeat the same thing here. Don’t worry, I’ve added a lot more contexts in my writing in detailed manner.…
So I encountered with a service that has to be restarted in every few hours or so because their memory consumption trajectory is like SpaceX’s Falcon 9 being launched toward ISS. Hmm. Golang is garbage collector language, so we just need to add *.Close() to every opened thing, right? Turn out it is not always the case. The characteristics of the service The main purpose of this service is to…
Running ./util/qmk_install.sh won’t work.

Motivation and Concept APM (Application Performance Monitoring) tools like Datadog are important for our system because they provide valuable insights into the performance, behavior, and security of our applications. They allow us to identify performance issues in real-time, improve application performance, troubleshoot problems, plan capacity, and identify security vulnerabilities. The…
I’m not talking about myself regarding the pull request (okay, I’ll talk about it a bit at the end of this blog post), there is nothing special about it. I want to talk about how a smooth and comprehensive onboarding process could let me create a pull request on the first day at work. All of these onboarding processes were done in less than 4 hours. Kudos for the people who helped me!
Setelah menimbang-nimbang cukup lama, akhirnya saya menjual CPU dan GPU saya selagi harganya masih tidak masuk akal, yakni Ryzen 5 3400g di harga 2.5 juta rupiah (harga beli 2 juta rupiah di tahun 2020) dan GTX 1660 Ti di harga 6.6 juta rupiah (harga beli 4 juta rupiah di tahun 2020). Terus saya pakai apa, dong? Sesuai judul, saya comot 5600g di harga 3.2 juta rupiah dan tidak menggunakan discrete…
How do I know if my team performs well? How to tell that with data? If we’re underperformed or didn’t meet the deadline, how to find the causes and tackle them? I was thinking about analyzing the entire activities in my team to get some insights, starting from GitLab issues. I put some filters to the issues: Has been assigned to someone Has mentioned in (at least one) a merge request…
After a year of having mining-capable GPU for gaming and despite the EIP 1559 plan, I decided to join the bandwagon in the end of April. Then I added some GPUs. Still, it’s a small rig. Quite late but I still got much profit. In this October I sold the rig and left with the 1660 Ti so I could continue to play video games. Some of the reasons: The daily profit is low in recent days Some…
He served me for almost eight years. Not very well but he did his job. Since COVID, I barely touch him and I believe my family could not get much advantage by having him around. So I let it go. Wakijo passed to my old friend, his previous owner.
I’m not talking about music that takes you back to the year where it got popular. That is a shared experience among other people. What I’m talking about is the music that could bring you up a specific memory about specific place or event, about yourself, in one strong dose. I don’t know if it works for others but here is how it works for me. Over and over again, almost infinite…
Suatu pagi di hari minggu saya “reuni” dengan teman-teman SMA yang satu ekstrakulikuler (Paskibra). Dari 14 orang cuma 11 yang berhasil dikumpulkan di grup WA. Yang hadir di zoom 10 orang. 8 sudah menikah, 6 sudah punya anak, 1 bahkan tinggal di Montreal nikah sama bule di sana. 2 dari 3 orang yang ga berhasil dikontak hidupnya kurang beruntung/bermasalah, sementara yang 1 tidak…
Saya dan saudara-saudara saya tumbuh di keluarga pengusaha yang ketat tentang apa yang boleh dan tidak boleh dilakukan oleh anak mereka. Bapak saya membolehkan apa pun selama hal itu terkait dengan sekolah. Pilihan atau keputusan-keputusan orang tua saya itu adalah hak mereka. Saya patut mematuhi mereka sampai saya diizinkan untuk mengambil keputusan penting sendirian. Namun saya menyayangkan satu…
Suatu ketika saya ingin meng-upgrade PC saya tapi kok rasanya berat hati untuk menyentuh tabungan. Rasanya kok keinginan tersebut tidak pada prioritas yang betul kalau sampai tabungan terkorek. Apa lagi sebentar lagi saya akan punya anak, tentu tidak betul kalau sampai pundi-pundi yang sudah diatur sedemikian rupa jadi terganggu. Terus bagaimana dong? Decluttering Ada orang-orang yang dengan mudah…
Today we’re pleased to announce our first nightly build (or “jahitan”) with package that build by our in-house toolchain IRGSH. This build featured Pop Shell extension package which marks our important milestone. The package help us to prove that IRGSH works as intended to help us to bring the source code to binary package, to injected it to signed repository then wrapped to a…
X509 is a complicated thing and EJBCA makes it easier to grasp. Eww you may find EJBCA is complicated as well. This post will guide you to specific case as example: CA that can issuing certificates for high education instutution. High education institution as end user can signing PDF files for their student certification. This post is not the best practice example but it can introduce you to how…
As a person who have been using Thinkpad computers for years, I was always missing the trackpoint feature. I want to type on mechanical keyboard but also I don’t willing to dismiss the nipple. There are few solution for this issue: UHK, Tex Yoda, Tex Shinobi. These all are expensive keyboard, the shipping cost alone is crazy. Trackpoint module is one of my goals while building UNK and I…

Sublime Text was my favourite text editor, I’ve been following it since its early days. The feature I most liked and can’t live without is the multiple cursors selection. Sublime Text lets you to select and edit string on multiple place at once based on pattern that you defined. I think it was a pain killer feature. The thing was that I always want to go back to Vim. The day I found…
My main keyboard was a Vortex Core. After my wife keep complaining about the noises (now you know it’s the blue one), I bought a Vortex Tab 75 with Cherry MX brown switches (she approved the new typing sound). It’s just a few weeks before I made an accidental disaster to the keyboard. I was programming on some stuff while snacking Dua Kelinci peanuts. The peanuts were in a small…
Although my GPU is not listed here, I can confirm that 1660 Ti works.

Buku ini cetakan kedua yang dicetak pada tahun 1928, saya temukan pada tahun 2017 di Surabaya. Harganya murah, cuma 20 ribu rupiah. Kisah yang diceritakan dalam buku ini sangat menarik, tak heran memenangi Pulitzer Prize. Umur buku ini hampir 1 abad. Buku yang paling tua yang pernah saya miliki. Tiap lembar kertasnya sangat tebal, setebal sampul buku tulis anak sekolahan, namun juga sangat rapuh.…
My wife has an old wish: a gaming platform to play both old games (e.g. Heroes of Annihilated Empires) and new games (e.g. The Witcher 3). I’ve setup a trial version VMWare Fusion on her Macbook Air to let her playing HoAE there but that old game does not run smoothly under VMWare DirectX 11 driver. Our Nintendo 3DS is not with us for now and our old Xbox 360 has been dead for a while (but the…
My motivation is that I want to get visualized report of my monthly expenses. I’m using Jenius heavily but their app does not provide such report. The original code was a CLI program and has been written since November 2019 then Jenius CoCreation Week 2020 Hackathon submission came out. I submitted the idea but it fail miserably. Since the original motivation is not to winning a hackathon…
This is my second attempt to write an algorithm problem for programming challenge. This time it’s written in Bahasa Indonesia. Seorang pustakawan baru saja diterima bekerja di sebuah perpustakaan. Sebelumnya buku-buku di perpustakaan tersebut tidak dikelola dengan baik dan peletakkannya tidak sesuai dengan kategori yang telah distandarkan. Ia ingin mengatur ulang buku-buku tersebut sesuai…
Inspired by Kodenesia (written by Yanmarshus Bachtiar), this is my first attempt to write an algorithm problem for programming challenge. Description Given the specific parameters (size, wall, start and target), you should build a virtual block map. If the size is 10, then it will be a 10x10 blocks map. Each block is numbered sequentially from left to right, then top to bottom. The initial value…
It starts with a story of young brilliant man named Zulkifli Lubis, the founding father of the first intelligence agency in Indonesia - Badan Istimewa, whose reports directly to Ir. Soekarno. BI then evolved to (but not in sequence/hierarchy) BISAP, BKI, KIN, Opsus, BAKIN, Satsus Intel and then the only intelligence service that serve the nation until now, BIN. The stories in this book also…
I got opportunity to talk about contributing to Mozilla Firefox at MozSpace Jakarta, based on my blog post. The Mozilla community here is friendly and fun. I hope we can held a hackathon for Firefox someday.
That was a fast and steep journey for me. Thanks to: MDAMT for his critics on the early architecture. Aldi for the help on the mobile app Asep who loves to talk about ideas My wife who lets me hacking on my portable computer while we are still on our honeymoon.
Kecup itu disimpan lama Karatan pada dasar benak Terhempas dalam mimpi liar Dikawani oleh kesepian yang paling subur Setelah hari-hari yang keras itu Kecup itu ditanam lama Kental oleh desir darah Dari sulaman asa yang indah-indah Sungguh aneh rasa itu Menjadi manusia Nyaris utuh
Hai, Awalnya dimulai pada suatu waktu di penghujung hari Jumat yang agak jenuh, saya mencoba mencari-cari sesuatu yang bisa dikerjakan dan tetiba kepikiran bagaimana sih kalau mau kontribusi kode ke proyek-proyek upstream skala besar seperti kernel Linux, peramban Mozilla Firefox atau Chromium? Mari saya mulai dengan Firefox. Harus bisa apa? Codebase Mozilla terdiri dari berbagai macam bahasa…
In late January 2019, I purchased a minimalist wallet from mindstorages.com. It’s handmade, looks cheap, err yeah, literally cheap. It advertised as long-lasting with durable stitching. I didn’t immediately write a review and want to use the wallet first for months before writing about it. My previous wallet is an ordinary foldable wallet and I was not happy with that. My entire stuff…
The reasons behind my decision to rewrite IRGSH are ranged from personal motivation to BlankOn project direction. After Uluwatu released, a hard disk died in one of BlankOn development server. Unfortunately, the machine is the important one. The hard disk contains IRGSH, the backbone of BlankOn Linux development. The fortunate side is this happened after Uluwatu released. A year before this…
In the beginning of 2019, I rent a comfortable room near my office so I could just do a walk to reach the office and meet my coworkers. What I don’t know early and the host didn’t tell is that someone that has bad records and strange behaviours stays here, a floor away up on me. Then something happened. Some underwears are missing (not just mine) and there is no CCTV placed on the…
Gmail is known for lack of privacy concern. Google reads your Gmail messages to build a profiling about you. It may improves our experiences on other Google services but I found that Google is collecting non-sense information of me (get this creepy news from HN). It may requires a lot of steps for moving on from Gmail since my other accounts on the internet mostly chainned into this particular…
I’ve few things to be achieved this year. Plastic I’ll focus on reduce and reuse. For recent years, I’ve been always say no when a cashier offers plastic bag. Easy peasy. It still far away from a level that I want to be : buy things with no/less plastic, stainless straw, dedicated water bottle, etc. Privacy I started to consider more secure and privacy oriented digital life. I…
I first learned about lockpicking during highschool. A locksmith introduced me to the basic understanding of how most locks work and how to break them. So, I tried it again with a transparent training padlock. It seems easy but on real locks, it really hard and needs patience as you can’t see the pin tumbler. Instead of using lock picking toolset, bending your own paper clip is more…
