洪 民憙 (Hong Minhee)

Hello, I'm an open source software engineer in my late 30s living in #Seoul, #Korea, and an avid advocate of #FLOSS and the #fediverse.

I'm the creator of @fedify, an #ActivityPub server framework in #TypeScript, @hollo, an ActivityPub-enabled microblogging software for single users, and @botkit, a simple ActivityPub bot framework.

I'm also very interested in East Asian languages (so-called #CJK) and #Unicode. Feel free to talk to me in #English, #Korean (#한국어), or #Japanese (#日本語), or even in Literary Chinese (#文言文, #漢文)!

Heya! 🥳 XenoAtom.CommandLine 2.0 is out: https://xenoatom.github.io/commandline/
It brings XenoAtom.Terminal.UI integration, validation, option constraints, and pluggable output rendering. After a month of terminal-focused work, it finally feels complete! 😅

I'm also consolidating my sites with shared templates via my Lunet generator, and I'm hoping to share it more broadly later this year.

Finally, the XenoAtom umbrella now has a landing page: https://xenoatom.github.io/ 🤩

So You Want To Write An Open Source Discord Replacement

Things you don’t need:
- federation/distributed systems
- multiparty end-to-end encryption
- an entirely new operating system kernel specially designed to—

Things you DO need:
- a user interface that is Normal
- the ability to use languages other than English and writing systems other than Latin
- higher standards of user experience than how irc actually works in the real world
- any fucking clue how Discord works and why people use it

I have muted replies to this post due to the usual reasons

My code is ugly, but it works! And I didn't have to learn all the intricacies of every one-off scenario between every single platform. Fedify hides that from me, and I'm so glad it does. I have no desire to go that deep.

Using @fedify to see how far I can get with very simplistic AP objects and activities. The tutorial and documentation was helpful and gave me a solid template to work from.

The fedify CLI is a great debugging tool, too.

The built in tunnel command makes it a snap to spin up temporary servers that are open to the public web for testing. Here I have two instances spun up so I can send activities between them.

@douginamug Of course, thanks!

Fedify 2.0 will probably be out by the end of February. No, it has to be.

@dansup Bower? Haven't been heard of it for a decade… 😂

TypeScript 6.0 beta is now published!

This release brings

- inference improvements for functions
- updates to package.json 'imports'
- Temporal APIs
- alignments for the upcoming TypeScript 7.0
- & more!

Try it today!

@FediTips Re: reply controls.

GoToSocial came up with a way (https://docs.gotosocial.org/en/latest/federation/interaction_controls/) to do this. It doesn't “solve” malicious servers, but it lets benevolent servers honor each other's inhabitants' wishes.

I'm drafting a “Fediverse Enhancement Proposal” document to make it easier for other projects to join GTS. It's progressing, but I have day job stuff etc. It might help to add a few collaborators.

Anyone comfortable w/ technical specs similar to this https://fediverse.codeberg.page/fep/fep/044f/ & want to help?

Sneak peak.

Good reads:

Incidentally, I did stop using Discord. No regrets.

Just promoted XenoAtom.Terminal.UI to 1.0! 🎉

I have added 2 new features from the preview: placeholder and brush gradients usable with text controls! 🎨

I'm going to see if I can add an extension to XenoAtom.CommandLine library to generate beautiful command line help and I will be hopefully done with this entire sidetrack of projects! ☺️

URI는 고유하지만 WebFinger 핸들이 동일한 계정들에 대해 각 구현체들이 어떻게 대응하는지가 궁금하다...

@pkgupdt 음, 그렇다기 보다는 ActivityPub 具顯(구현)이 어카운트의 캐시에 依存(의존)하면 안 된다고 보시면 될 것 같아요. 🤔

@pkgupdt 實(실)은 도메인 네임 再使用(재사용)이 可能(가능)하긴 합니다. 서비스 終了(종료)하기 前(전)에 모든 어카운트에 對(대)한 Delete 액티비티를 날리면 (이른바 self-destruct) 確實(확실)하게 可能(가능)하고, 그렇지 않더라도 時間(시간)이 좀 지나면 可能(가능)해야 합니다.

@deach I'm not particularly knowledgeable about them. I used to spend a lot of time on implementing localization stuff, but not much on vertical text unfortunately.

This reminded me of articles by @huijing which have a lot more details and background:

Early bird CFP for @COSCUP 2026 seems available now. Anyone interested?

And of course, I'm already taking the first steps.

Someone at #FOSDEM asked us to put some promotional materials on our website that they could print for an event. There is now a section for that on the Branding page with our first poster:

@dansup Isn't Matrix enough for you? 😅

@mizblueprint that’s not the point though. She wants to participate in the world and discover new things outside her bubble, but only when those things don’t make her uncomfortable. That’s the point
