kwonjiwon.orgoeee.cafeUpdate: we've decided to go ahead and submit the CFP to 
@COSCUP 2026. The track will be called Fediverse & Social Web—think FOSDEM's Social Web devroom, but in Taipei. #COSCUP is free to attend, like FOSDEM.
If the track is accepted, would you be interested in coming to Taipei (Aug 8–9) to give a talk?
(Boosts appreciated!)

I'm super hyped to announce that Bluesky Socal PBC has given me a grant to work on the Federated Credential Management (or FedCM) standards to make them really work for all decentralized web applications.
This is why I stepped up to be an Invited Expert with the W3C FedID Working Group earlier in the year. The missing part at that time was "how do I fund this work?" so I'm super happy that Bluesky Social PBC really came through with a grant to fund this work.
A really interesting thing that Bluesky Social PBC did here was they could have said "just make this work for AT Protocol" but instead they said "make this work for the entire decentralized web", and the contract explicitly states I should be working with the IndieAuth, Solid and other communities interested in federated and decentralized identity to make this happen.
Legal vs. Legitimate, good article by

> Whatever courts eventually decide about AI reimplementation, the question we need to answer first is not a legal one. It is a social one. Do those who take from the commons owe something back? I think they do. That judgment does not require a verdict
"Can the commons expect something back from those who extract value?" is a key question of Social experience design. The answer forms one of 3 core principles: The Mindfulness principle.
No. You can't expect *anything* back. That philosophical insight is crucial to organizing a healthy commons that's able to retain its value and evolve.
Paint any principles and values on a flag but as long as the battle is scattered farmers holding feeble Copyright Law pitchforks against a vast drone army, its no use. Know thy enemy helps too. It's not proprietary code or corporations. It's hypercapitalism: The Rules of Battle.

I've been saying for a while that we need something like FediCon in East Asia. A dedicated conference is still a stretch, but I've been thinking about a smaller step:
@COSCUP 2026 (Taipei, Aug 8–9) is accepting proposals for community tracks. It might be worth trying to open a Social Web track there—something in the spirit of the Social Web devroom at FOSDEM.
Nothing is decided yet, but if you're working on #ActivityPub, the #fediverse, or anything in the social web space and might be interested in speaking (or co-organizing), I'd love to hear from you.
東아시아에도 FediCon 같은 行事가 있으면 좋겠다는 말을 여러 番 해왔는데요. 獨立的인 컨퍼런스는 아직 어렵더라도, 작은 첫걸음으로 생각해보고 있는 게 있습니다.
@COSCUP 2026(臺北, 8月 8日–9日)이 커뮤니티 트랙 提案을 받고 있어요. FOSDEM의 Social Web devroom 같은 느낌으로, 거기서 Social Web 트랙을 열 수 있지 않을까 하고 構想 중입니다.
아직 確定된 건 아무것도 없지만, #ActivityPub, #聯合宇宙, 或은 소셜 웹 全般을 다루고 있고 發表나 共同 오거나이징에 關心이 있으신 분이 있다면 이야기 걸어주세요.

SheetKit은 기존 Node.js 엑셀 라이브러리들의 성능 한계와 기능 제약을 해결하기 위해 Rust로 개발된 고성능 스프레드시트 라이브러리입니다. 저자는 대량의 데이터 처리와 동적 템플릿 생성을 위해 Rust 코어 기반에 napi-rs를 활용한 Node.js 바인딩 구조를 설계했으며, 코딩 에이전트와의 긴밀한 협업을 통해 단 일주일 만에 초기 배포부터 v0.5.0 릴리스까지 달성했습니다. 특히 자바스크립트 객체 생성에 따른 가비지 컬렉션(garbage collection) 압박을 줄이기 위해 이진 버퍼(binary buffer)를 통한 데이터 전송 방식을 도입하고, 지연 로딩(lazy loading)과 스트리밍 리더 기능을 통해 대용량 파일 처리 효율을 극대화했습니다. 벤치마크 결과 기존 라이브러리 대비 압도적인 메모리 절감과 속도 향상을 보여주었으며, 특정 쓰기 시나리오에서는 V8 엔진의 최적화 덕분에 Rust 네이티브보다 빠른 성능을 기록하기도 했습니다. 현재 164개의 수식 함수와 43개의 차트 타입을 지원하며 실제 업무 현장에 성공적으로 적용 중인 SheetKit은 Node.js 환경에서 대규모 엑셀 데이터를 다루는 개발자들에게 강력하고 효율적인 솔루션을 제공합니다.

SheetKit is a high-performance Rust-based spreadsheet library designed for Node.js to address the limitations of existing Excel processing tools. Developed over a single intensive week using an architect-led workflow with coding agents, this library leverages napi-rs to provide comprehensive support for the OOXML specification, including complex features like charts, conditional formatting, and extensive formula functions. To overcome the memory overhead and garbage collection pressure typical of JavaScript-heavy Excel libraries, the architecture utilizes a specialized raw buffer FFI protocol and lazy-loading mechanisms. These optimizations allow SheetKit to handle massive datasets with a significantly reduced memory footprint, occasionally outperforming native Rust implementations in specific write scenarios due to efficient string interning within the V8 engine. The project introduces advanced capabilities such as streaming readers for forward-only processing and copy-on-write saving to bypass unnecessary re-serialization of unchanged data parts. This development represents a significant step forward in Node.js data processing, offering a robust and scalable solution for developers managing high-volume or complex spreadsheet workflows.

I finally got the data transfer from the AISC110C high-speed camera sensor working!
It's a 5€ chip that outputs 80x120 video at up to 40k fps.
Data is read with a Xilinx Spartan7 and transmitted via USB3 with a Cypress FX3, each on its own little PCB.
The front PCB is exchangeable, making this a neat modular platform. I already have an analog video frontend with the ADV7182 and am working on a Cameralink interface.
Videos are coming tomorrow, I need more light for the high framerates.

Calling all #fediverse developers for help: I'm currently trying to implement a #reporting (#flag) feature for Hackers' Pub, an #ActivityPub-enabled community for software engineers. Is there a formal specification for how cross-instance reporting should work in ActivityPub? Or, is there any well-documented material that explains how the major implementations handle it?

If your company uses Rust a lot and would like to support it and talk about how that support can either indirectly or directly benefit its Rust-writing employees, I'm happy to chat to explain both funds and make the connection to the right fund for you. Or just skip directly to one of the funds if you already know ppl there!
I think I have identified a fairly significant flaw in how the #Fediverse currently operates. Hear me out.
The Fediverse currently consists of all sorts of different systems - #Mastodon, #Friendica , #Pixelfed , #PeerTube, #BookWyrm , and so forth. And while they are all connected via the #ActivityPub protocol, they all have different functionalities and different ways of presenting themselves. Which is as it should be, because Diversity Is Our Strength(TM).
However, it is here that the ActivityPub-based interactivity hits its limits - for usually, you can either experience the relevant system as it was intended, or you can interact with it, but not both - _unless_ you have an account on the same system (though not necessarily on the same instance).
Let's say that you are a Mastodon user who looks at another person's BookWyrm page. You scroll through their books, posts, and comments. Then you see some comment you want to comment on yourself, but can you do so?
Not directly. You need to figure out the URL of their comment, and then copy and paste that comment into the search bar of your Mastodon instance. Then it will show up in the same format as a Mastodon post, and you can interact with it - boost it, like it, comment on it.
Sure, it works, but it's a whole lot of tedious effort.
Or you can search for the user account in Mastodon and scroll through all their posts and comments as if they were a Mastodon user - and thus, you will miss out on all the unique user interface features of BookWyrm.
So what is missing?
Well, Mastodon already has an "Open original page" feature when looking at someone's post. What we need is an "Open original page AND AUTHENTICATE" feature. This way, the target instance (whatever software they are using) could acknowledge the viewer as an external user who could nevertheless fully interact with the local user interface, including the ability to boost, like, and make comments.
This is something that should be theoretically possible to implement, right? #FediHelp
We are currently fighting against a DDoS attack against our service and our status page. We are analyzing network traffic with the help of our ISP at the moment and let you know once we have updates to share.
A while back I mentioned the idea of “Fedify Studio”—a web-based toolkit for #ActivityPub debugging and development. I've been quietly working on shaping that idea into something more concrete.
Nothing to announce yet, but it's looking like this might become a team effort rather than a solo project, which would be nice. We'll see how it goes.
I'd love to go to @fosdem 2026, but Brussels is just too far from Seoul… and the plane tickets are so expensive. 😭
Hey #fediverse people, I've an ask: If you appreciate all that I do for the fediverse and open social web, and you'd like to see me continue to do that work, please support my work financially.
Right now I'm having to look for work outside of the Fediverse because I simply cannot make ends meet.
I need €60-70k per year to support myself, with costs everywhere feeling increased (so that number may even be too low)
Right now, year to date, I've received a total of €20,170 in financial support from the community, and €22,450 from NLNet grants. I've also only had minimal freelance work this year, as I've been busy on grant work & try to focus on the fediverse & open social web.
So my total income isn't yet enough to be regularly sustainable. I've had problems being able to make rent payments this year because cashflow on grants comes in large chunks usually months after the work has been done.
So if you want to see me keep doing what I'm doing, please support my work!
