Hi! I'm Ho Sim
(심호).

I'm building a system that privately organize personal data and create apps that reveal insights from them. I'm invested in technologies that empower individuals to get more done and enhance digital freedom.

I initially had this as a part of 2024 Reflection & 2025 Goals, but I decided it was too long to not be its own blog post.

2024 Reflection & 2025 Goals

First, I'd like to make it clear that I hate overly positive posts such as those on LinkedIn. They sound fake as hell - I bet at least half of them are. Everyone sounds like they are forcing a smile to look good to their future employer. ...

Learn these concepts before building a home server

I learned a lot throughout the weeks I spent fiddling with this tiny computer. This was the first time I created a Docker container and did any sort of network administration. This post will go over the challenges and requirements of a home server and give an overview of the solutions and concepts I learned on the way.

Think about it. Biomedical researchers don't plan to research cure to cancer for the rest of humanity. City planners don't plan to build infinite number of cities, and washing machine manufacturers don't plan to make infinite iterations o...

Dev tools you should be using

I think all software developers can agree on spending hours on eliminating the smallest inconveniences for the sake of efficiency (whether it actually improves efficiency is another matter). This is my collection of tools that I use for j...

How Did I Get Here?

When I grew old enough to start considering my future career, I was certain I wanted to become a mechatronics engineer and build cool robots. That abruptly changed at the age of 17 as I realized there was so much I could contribute to humanity through cellular agriculture research. And just as I was confident my goals wouldn't change, I decided to drop everything and pursue computer science.

2022 was one of the most unexpected years of my life. I was kept busy with moving to another country and pursuing computer science, dropping my beloved study in biotechnology.

Web development was the highlight of 2021. I'm now actively learning full-stack web dev, and fairly confident with the front-end. Out of all things, the most important thing I learned was that this is something I'd really enjoy pursuing a...

For 2020, I spent majority of it on getting used to the army. I attempted to learn Kivy, tried to get in to reading books on computer science, and learned ALOT for Unity game development. I wish I studied algorithms more efficiently and p...

Software Dev Log 6

I'm not sure if I'm just falling into a slump or my mental health isn't doing well this month (like how it does every few months), but I haven't done much in the last 2 weeks. I also have real life stuff to blame, like how I was extra bus...

It's been a bit more than two weeks, but still this is a good time to write this. I don't have much to say for most of the weeks, but I made some big progress in the last few days and I'm excited to share it.

Software Dev log 2

It took almost a month to finish writing my first log, which is not really ideal when the plan was to write about once a week or two. It's not as easy when you aren't used to writing, along with trying to pack it in a pretty busy schedule...

It's a little weird to call this series a dev log, because I'm far from developing anything at the moment. I'm currently working on two things;

Python UI Development, D-2

I learned a bit of the widgets last night, and today I tried and see if I could separate the widget initialization in to its own method from `MainWindow.init()`. Long story short, it didn't work. Not only did it not work, my whole UI didn...

I've been off this project long enough that anyone can consider it over from my last post. And well, it was. I wrote and completed my thesis on it, presented it in front of all other contestants and judges, and received an award for being...

As you can see with the spacing between each entry, I am a terrible student researcher. Perhaps the fact that only 4 was successful got me demotivated. Maybe I was just waiting for my teacher to buy some kind of food for the fruit flies, ...
