In the last post, I talked about why I’m building Bokaka. This time, let’s get into the how - choosing the right hardware, writing firmware from scratch, and the painful journey of getting two cards to actually talk to each other. Choosing the MCUThe first decision was picking the right microcontroller. I had a few hard requirements: USB support - Bokaka cards need to plug into a computer for syncing with NEXI, so native USB was non-negotiable Built-in unique ID - STM32 chips have a factory-...

It took me a while to put together the review for 2025, in a sense I don’t think I have done anything special or worth writing this year. But then again, gotta keep up with the tradition.

Why VOCALOIDVOCALOID was never just music software to me. It’s a whole movement built by creators - producers, artists, fans - who made something together without needing permission from record labels or agencies. Miku belongs to everyone. Her songs come from bedroom producers, her art from passionate fans, and her concerts celebrate a community that built her legacy together. What makes it special is the spirit of the creators. Every producer puts a piece of themselves into their songs - the...

🎉 Update: I’m Joining Amptalk!After much more reflection and consideration since writing this post, I’ve decided to accept the offer and join Amptalk. The team’s warmth, the company’s vision, and the opportunity for growth ultimately won me over. Sometimes the right decision just needs a little more time to become clear. I’m excited to start this new chapter and see where this journey takes me! Meeting AmptalkEarlier this year, I started to seriously consider a shift—not just a job change...

Recently, I formally withdrew from the hiring process at CADDi, a fast-growing B2B manufacturing platform in Japan.I applied for a Senior Software Engineer position and went through multiple rounds of interviews and evaluations.By the end, I realized this opportunity—and the culture behind it—was fundamentally not for me. Here’s what happened, and why I chose to walk away. Interview Process SummaryThe process was well-organized at first and included: Initial HR screening A deep dive with an...

Haven’t been posting yearly reviews for a while, mainly due to laziness. But I’ve been busy working, 2023 and 2024 I have dedicated most of my time acquiring the private pilot license and getting myself more organized.

As I approach closer and closer to the flight test for my PPL (Private Pilot License). I want to write a short summary of what I did and how I planned my PPL. Working on PPL is not for the faint hearted, and your mileage may vary. I don’t think I am very exceptional at flying since it did took me to 30hr flight time to even get my first solo. But this is aimed to give you a big picture on a “average” plan for PPL PreparationTo prepare, I ordered all the required book and tools for study thi...

Recently I’ve been asked by many people about how to preserve their SEGA Nu/Alls console, and I want to take this chance to leave some instructions so people can attempt before reaching out and waiting for me slowly reply them 🥹. As we all know, the SEGA Nu or Alls are protected by Bitlocker with TPM + Recovery Key. Since there is a risk of system configuration change that triggers Bitlocker recovery, many of you (including myself) want a way to crack Bitlocker first and ensure in the e...

Around the time of the pandemic, or even before, I acquired a couple FPGA board with the intend to learn more about FPGA programming. The Alchitry Au is a development board based on the Xilinx Artix 7. At that stage, I wasn’t really into doing coding in the Xilinx toolchain since its big and not open source. The Alchitry Cu is a lower powered board based on the Lattice iCE40, even lattice offers their own toolset called iCECube, there are open source alternatives. (yosys, nextpnr, etc) Ov...

在家工作了已经快两年了，从2020年三月份开始在家工作的时候吃饭就是一个问题。因为每天不用去公司，加上运动量减少，如果不好好控制饮食，身体久了就会吃不消。在之前我有在减肥，但是自从在家工作体重就很难控制，我从19年年底的150斤慢慢的涨到了175斤。在家工作主要有以下几个麻烦： 时间有限 选择食谱困难 增加额外工作量 我之前有考虑过几种可以简单解决吃饭问题，但是最后因为种种原因没有坚持下去。 每周制定食谱，周日购物准备（每餐准备时间 10分钟， 周日准备1-2小时） 好处 种类选择很多 简单 准备时间短 坏处 周日工作量很大 准备好的蔬菜在周末会变不新鲜 并没有减少洗碗的工作量 每周指定一种，周一中午制作一周的分量（每餐准备时间 2-5 分钟， 周一准备30分钟） 好处 简单 每天只需微波 洗完工作量并不多 坏处 种类很少 准备好的饭菜在冰箱放一周会变不新鲜 沙拉三明治（每餐准备时间2-5分钟，周末准备30分-1小时） 好处 简单 几乎不需要洗碗 坏处 单调 不适合冬季 我发现在家工作吃饭最麻烦的就是很难满足以下几个要求： 简单 方便 丰富 健康 不需要很长准备...
