TL;DR​

• includeIf 문법을 사용하면 특정 조건을 만족하는 git 설정 파일만 적용할 수 있다.
• 업무 환경과 개인 환경을 분리하는데 유용하다.

Problems​

• 업무용 개발 환경과 개인 개발 환경이 분리되어 있다.
• 그런데 global git config 는 개인 환경 기준으로 설정해놓고 사용하다보니 chezmoi 로 설정파일을 동기화할 때 업무 개발환경에 개인 설정이 overwrite 되어 적용되는 문제가 있었다.
• 어떻게해야 업무 환경과 개인 환경을 안정적으로 분리할 수 있을까?

Problems​

• 메세지 스펙이 변경될 경우, 의존하고 있는 모듈 or Git Repository 마다 DTO 업데이트가 필요하다.
  • 하위호환성이나 상위호환성이 자주 깨진다.
  • DTO 관리의 복잡도가 선형적으로 증가한다.
  • Java 는 특히 Json 기반의 메세지를 다루기에 불편한 점이 많다.
• 카프카는 ByteArray 형태로 메세지를 전송하나, 애플리케이션 레벨에서는 이를 역직렬화하여 관리하는 것이 권장된다.
  • payload 에 데이터를 담을 때마다 ByteArray 로 직렬화하는 과정, 그리고 이 반대 과정이 매번 이루어진다.
  • 코드 복잡도 상승
  • ByteArray - JSON - Object

Overview​

회사에서 시켜서, 혹은 개인의 니즈로 인해 daily 라고 부르는 일일 노트를 적곤 한다.

필자 또한 daily 를 적는데, 처음에는 회사의 요구로 인해 적기 시작했지만 적는 방식에 대해 많은 시행착오를 거쳐서 현재는 개인적인 용도로도 많이 적게 되었다.

이런 daily 는 어떻게 작성해야 편하게 적으면서도 활용도를 최대한 높일 수 있는지 간단하게 적어보려고 한다.

Overview​

Following up on the previous post about the best apps, let's look at recommended Command Line Interface (CLI) tools. All the tools introduced here have been used by me for at least 6 months and are essential installations when setting up new equipment.

zoxide​

GitHub - ajeetdsouza/zoxide: A smarter cd command. Supports all major shells.

A tool that eliminates the need to remember paths for directories you've visited before. For example:

cd ~/.config/somewhere/longlong/path

# Next time, you can visit directly with this command
z path

This is incredibly convenient as you no longer need to remember where specific configuration files are located. Using zi displays a priority list, allowing for fuzzy searching.

Once you try it, you'll never want to go back to the time before using this tool.

mise​

GitHub - jdx/mise: dev tools, env vars, task runner

A version manager for various environment variables, languages, and packages. It's highly stable due to its architecture and fast thanks to its Rust implementation. Its intuitive commands significantly reduce the learning curve.

I've already introduced it in a blog post, showing how much I love this tool. While there are several similar tools that can serve mise's role, I personally think it's the most recommendable among them. For example, direnv can be completely replaced by mise, and nix is overly complex with reduced versatility.

If you're a programming multilingual dealing with various languages, you should definitely try this.

chezmoi​

chezmoi

If you use multiple devices, synchronizing development environments can be quite troublesome, especially for developers who frequently use CLI.

If you're not planning to give up on synchronization entirely and are wondering how to synchronize, try chezmoi. Even if you purchase new equipment, you won't need to spend time on initial setup.

Like mise, there's a post about how to use it on this blog for reference.

fzf​

GitHub - junegunn/fzf: :cherry_blossom: A command-line fuzzy finder

With about 70k GitHub Stars, does it need more explanation? (For reference, spring-framework has 57k).

This open-source fuzzy finder, maintained by Korean developer junegunn, boasts incredible versatility through standard input/output piping.

If you need search functionality, regardless of the type, just use fzf. It's so widely used by various packages that you might have been using it indirectly without knowing of its existence.

fd​

GitHub - sharkdp/fd: A simple, fast and user-friendly alternative to 'find'

Replaces the find command.

Written in Rust and up to 50% faster than find. It has clean highlighting and much more intuitive command options compared to find.

ripgrep​

GitHub - BurntSushi/ripgrep: ripgrep recursively searches directories for a regex pattern while respecting your gitignore

Replaces the grep command. Although named ripgrep, it uses rg as the command.

Similar to fd, it's written in Rust. Compared to grep, you can get much more diverse information from the output. The commands are intuitive and easy to use, and with its speed, there's no reason not to use it.

Truly 'RIP, grep'.

lsd​

GitHub - lsd-rs/lsd: The next gen ls command

Replaces the ls command.

The ls command is incredibly frequently used. While the command itself is old, it doesn't provide diverse information in its output. Using lsd can completely replace the existing ls.

bat​

GitHub - sharkdp/bat: A cat(1) clone with wings.

Replaces the cat command.

While the cat command is simple output, using bat provides code highlighting. Sharp developers might worry about line output interfering with shell piping, but it doesn't interfere at all. Don't worry and enjoy this modern tool.

I use bat with an alias set to cat.

HTTPie​

HTTPie – API testing client that flows with you

Replaces curl.

Although there's also an APP version, making me wonder which article to include it in, I personally only use the CLI version, so I included it here.

The reason I prefer HTTPie over curl is that it's very, very intuitive. Simple GET requests can be sent like this:

https httpie.io/hello

The response comes formatted like this:

Think about curl responses. Developers like pretty things too.

Orbstack​

OrbStack · Fast, light, simple Docker & Linux

Replaces Docker Desktop.

When using Docker containers, it becomes a bit faster and eliminates some bugs. But its true value shows when using VMs - it can run VMs very lightly on Macs, where traditionally VMs were difficult to use. If you need to test on OSes like Ubuntu or Kali Linux, try using orbstack for very fast and convenient management. Personally, it was a very interesting experience.

atuin​

GitHub - atuinsh/atuin: ✨ Magical shell history

While chezmoi could synchronize tool settings, atuin can synchronize command history used at work. No more struggling to remember what commands you used at work.

atuin history list | fzf

trash-cli​

Implements "trash bin" functionality in the terminal. Therefore, you no longer need to fear rm -rf /. Because you can restore anything.

Do you need more reason than being free from rm -rf /, the developer's greatest enemy?

Conclusion​

So far, I've introduced several tools that I personally really like.

In fact, there are many more tools worth recommending, but whatever anyone recommends, what works best for you is what you're comfortable with. Find and try others that suit your environment.

Overview​

It's been 13 years since I started using only MacOS.

Even before starting my career as a developer, I had a hobby of exploring various tools to use Mac more conveniently. It was fun just trying out new tools.

Many tools have come and gone through that journey.

This time, I want to introduce the tools that have survived and continue to help me overcome various challenges. I'll be introducing them in two parts - Apps and CLI, and this article will cover the App edition.

Overview​

This is a brief session prepared for those who don't know where to start with their presentations. We'll introduce various tools that can be used for network monitoring and experimentation, along with explanations of how to use them.

Environment​

What kind of environment should we prepare to study networking? While it depends on the topic you want to study, let's look at some commonly used methods.

Overview​

Docker has six network types in total:

• Bridge
• Host
• IPvlan
• MACvlan
• Overlay
• None

I think many backend developers either don't know much about network types or only use bridge networking even if they do. I was also curious about this topic and conducted a study. This article is an excerpt from the content I presented during that study.

We'll conduct practical exercises using Orbstack to run VMs.

Overview​

So many things happened in 2024.

I'm starting this retrospective with such a cliché sentence because I can't think of anything better. Not everyone can start their writing with a sentence like "Mother died today." Or can they? I'm not sure.

Overview​

What makes code easy to review?

The Guide to Writing Readable and Review-Friendly Code is a book written by a current LINE developer based on their experiences. It thoroughly covers various methods and principles to enhance code readability.

Personally, I think it's an excellent introductory book on code conventions. Let me explain why.
