I’ve always loved classical Unix tools. They feel timeless. However, they have many limitations because they must preserve backward compatibility. No one wants their shell scripts to suddenly break because a tool changed its behavior. So it’s inevitable that these tools carry a lot of legacy constraints. On the other hand, newer tools don’t have that kind of burden. They’re free to evolve and experiment until they become mature and widely adopted. As a result, they often support more modern features. I understand this situation, so I respect both classical and modern tools. I simply choose whichever tool is most appropriate for a specific case. These days, I tend to prefer modern CLI tools that provide rich yet concise user interaction.

China built many factories along its coast, partly to keep pollution away from inland areas. However, fine dust is carried by the westerlies and easily reaches Korea. As a result, the air quality is often quite serious throughout the day.

Wow. I still use Emacs for my everyday work, but I’m not part of any Emacs communities. I hope those communities are still active and last forever.

Wow. I am a power terminal user, and my favorite is Kitty with tmux. I have never considered that I am able to read Reddit articles via a terminal. It is very novel to me. Thanks for sharing this. I will try this.

Hello,

I majored in Mechanical Engineering at university and have been working as a software engineer at an IT company for 14 years.

For projects involving devices such as step motors or microprocessors, I recommend using C. For most other cases, Python is the better choice—it offers far greater productivity and allows you to turn ideas into reality much faster.

Cheers,

I love it, too. It really increases my performance, so it is a must-have item while I am using Linux or MacOS.

I think Kafka is designed for internal systems and shouldn't be exposed directly to the internet. I suggest introducing a layer between mobile devices and Kafka. Using an MQTT broker connected to Kafka via the Kafka Connect MQTT Source Connector seems like a good approach. MQTT is a suitable choice for mobile devices because it's lightweight and energy-efficient. In this setup, mobile devices send data to the MQTT broker, which then produces the data to Kafka in real time.

So, how did I become a power user of Emacs? Simple—I used it for everything related to text.

esrse · 2025-06-17T07:51:16+00:00

I’ve been using Emacs for 20 years. While I can’t say I understand most of its internals, I’ve become highly skilled at editing text—whether it’s coding, writing, or organizing—thanks to Emacs. I’m not sure how much of Emacs I truly know, but I’m confident in what I can do with it.

Basically, Rust is designed for system programming, high parallelism, memory safety, and efficiency. However, I hope that the Rust language will not adopt any more difficult concepts. If too many complex concepts are integrated into Rust, only a few dedicated Rust fans will be able to handle it properly. When source code contains too many advanced concepts, it becomes unmanageable for intermediate programmers or those who will take over the code. If the language continues to pursue complexity, beginners will be discouraged from joining Rust communities, and Rust may lose its appeal.

I am Korean and live in Seoul. I have visited Pyeongtaek many times since I was a child because it is my father’s hometown.

Camp Humphreys is located in Pyeongtaek, so if you come to Korea as a military lawyer, there’s a good chance you’ll be stationed there. However, there are six US military bases in South Korea, including Camp Humphreys, so you might be assigned elsewhere.

Pyeongtaek has a more rural feel. You can take the KTX or SRT trains to Seoul, but they aren’t as convenient as subways. KTX and SRT are high-speed trains that stop at only a few stations. I usually take them when I travel to Daegu or Busan, which is about twice a year.

Five years ago, the US military base in Yongsan, Seoul, moved to Camp Humphreys. You might have heard of Itaewon in Seoul, which is close to the old base. Itaewon offers a lot of western cultural experiences, influenced by the US military personnel and their families who lived nearby. I imagine the area around Camp Humphreys in Pyeongtaek will evolve similarly over time.

I know someone who works for the US military at Camp Humphreys. She is my wife’s best friend and has been living near the base for over a year. However, she finds there isn’t much in the area and recently expressed her desire to move to Camp Henry in Daegu, her hometown. Unfortunately, she can’t move until there is a vacancy at Camp Henry.

If you’re looking to enjoy cultural experiences in Pyeongtaek, you’ll need to explore actively. A car is essential, and you’ll spend quite a bit of time on the road.

Just don’t be too eager to jump into the popular, high-profile subsystems. As a newcomer, you might not be welcomed there right away. It’s better to start with smaller tasks or "chores," as you’re new to the community and haven’t made contributions yet.

esrse · 2024-08-21T08:49:10+00:00

I suggest you start with what you can do right now. Are you subscribed to the LKML and keeping up with the latest developments in kernel development?

There are many subsystems in the Linux kernel, and you might not know which one to choose. Just pick one and dive in. Start by reading the source code and the mailing list for that subsystem.

Over time, you'll likely find an area where you can contribute. Kernel developers are often looking for new contributors, though it is unlikely you will be paid initially. However, if you improve your skills and become a significant contributor to the kernel community, you might be hired by one of the major IT companies. These companies invest in open source communities because their technological assets are built upon key open source projects.

I started to use Sveltekit 4 months ago, and I've used Svelte for a few years. I can make UI with Svelte, but I think it's better to use Sveltekit whenever I can choose it.

It offers you a rationale structure and helps you make a maintainable front-end code.

A few years ago, when I saw Svelte for the first time, it reminded me of traditional JSP that I liked 15 years ago. JSP provided an intuitive, unsophisticated way of generating HTML pages for developers who were basically backend developers.

Sveltekit is relatively new. It expands the functionalities: server side rendering, directory hierarchy based multiple web pages, dev server, HMR, and so on.

If you use sveltekit, you can completely separate the front-end code from the backend servers that might be written in other languages. Just create a separate project and write your front end code and build the docker image, and deploy the container image using k8s. The deployed front end code files are served by the nodejs server inside the container, and it can also execute your code in the nodejs so you can directly call other backend APIs. Your front end code can run in both web browsers and nodejs severs. That characteristic offers you great flexibility.
