            <summary>야크 셰이빙: 새로운 오픈 소스의 원동력 / Embracing yak shaving</summary>
            <description>**야크 셰이빙**([yak shaving])이란 원래 하려던 일을 하려다 “그 일을 더 수월하게 하기 위해서”라는 명목으로 원래 하던 일을 멈추고 다른 일을 시작하고, 또 그 일을 하기 위해 또 다른 일을 시작하는 식으로 일을 잔뜩 벌리는 것을 뜻합니다. 원래는 그렇게 일을 벌리기만 하다 결국 원래 하려던 일을 하지 못한다는 부정적인 뉘앙스를 품고 있지만, 야크 셰이빙이 반드시 나쁜 것만은 아닙니다.

발표자 홍민희는 분산형 소셜 네트워크인 연합우주(fediverse)의 열렬한 지지자로, 연합우주를 사용할 때 개인적으로 불편했던 점들을 고치기 위해 2년 전부터 [Hollo], [Fedify], [LogTape], [Hackers&#x27; Pub], [Upyo], [Optique], [BotKit]과 같은 여러 오픈 소스 프로젝트들을 연쇄적으로 만들게 되었습니다. 처음에는 아주 사소한 불편함을 해결하기 위한 것이었지만, 하다 보니 점차 다양한 부산물을 만들게 된 것입니다.

발표자는 지난 2년을 돌아보며 다양한 새로운 오픈 소스 프로젝트의 원동력이 될 수 있었던 야크 셰이빙 정신에 대해 이야기하고, 이 방식이 다른 사람들에게도 통할 수 있다는 이야기를 하려고 합니다.

*[Yak shaving]* refers to the situation where you&#x27;re working on a task, but you stop to start another task with the justification that it will “make the original job easier.” This can lead to starting yet another task to accomplish the second one, creating a cascade of work. While the term often carries a negative connotation—implying that one gets endlessly sidetracked and never completes the original task—yak shaving is not necessarily a bad thing.

The speaker, Minhee Hong, is an avid supporter of the fediverse, a decentralized social network. To fix personal inconveniences they encountered while using the fediverse, they started a chain reaction of creating several open source projects two years ago, including [Hollo], [Fedify], [LogTape], [Hackers&#x27; Pub], [Upyo], [Optique], and [BotKit]. What began as an attempt to solve a very minor inconvenience gradually resulted in the creation of various byproducts.

In this talk, the speaker reflects on the past two years to discuss the yak shaving spirit that became the driving force for numerous new open source projects, and will make the case that this approach can work for others as well.

            <description>Onboarding contributors can be a difficult part of the open-source project lifecycle. Just like expanding your team at work, there is a lot that con go wrong if there is a mismatch in expectations.

This talk covers a mix of concrete and high level things that maintainers can do to improve their onboarding process, and things to avoid. It draws an my 20 years of contributing to open-source projects, onboarding dozens of contributors to projects I maintain, and mentoring for Google Summer of Code. And for new projects, I&#x27;ll present some things to consider before starting that will improve your chance of success in building a vibrant community.</description>

            <summary>AT-protocol and Bluesky, a new approach to Open Social</summary>
            <description>What can you do if a post you uploaded to social media suddenly isn&#x27;t visible or gets deleted?
If a web service you&#x27;re using suddenly shuts down, how can you protect the creative work you&#x27;ve accumulated over years?
Is there no way to own and control the recommendation algorithm, which is a double-edged sword?

Attempts at decentralized social media already exist, but AT-Protocol proposes a slightly different direction with a new approach to data ownership and service diversity.

The reason people are flocking to Bluesky after leaving X (formerly Twitter) or Facebook,
and why tangled.org is emerging as an effective alternative to GitHub as a hub for developers,
stems directly from the characteristics of the AT-Protocol.

In this session, we will discuss the following three topics:

1.  **How AT-Protocol works** - Learn how to navigate in the ATmosphere with AT-URI
2.  **How Bluesky works** - An introduction to Bluesky, a representative service based on AT-Protocol, and how it differs from other social media platforms.
3.  **The present and future of ATmosphere** - An introduction to other services within the AT-Protocol ecosystem, ATmosphere, and emerging new ideas.

SNS에 올린 글이 어느날 갑자기 노출되지 않거나 삭제되면 어떻게 할 수 있을까요?
사용중인 웹서비스가 갑작스럽게 문을 닫는다면, 수년간 쌓아온 창작물을 어떻게 보호할 수 있을까요?
양날의 검인 추천 알고리즘을 소유하고, 통제할 방법은 없을까요?

탈중앙 SNS를 향한 시도는 이미 존재하지만, AT-Protocol은 데이터 소유권과 서비스 다양성이라는 새로운 접근으로 조금 다른 방향을 제안합니다.

X(구 Twitter)나 Facebook을 떠난 사람들이 Bluesky로 모이는 이유,
그리고 개발자들의 허브로서 tangled.org가 GitHub의 효과적인 대안으로 떠오르고 있는 이유 역시
바로 이 AT-Protocol의 특성에서 비롯됩니다.

이 세션에서는 다음 세 가지 주제를 중심으로 이야기를 나눕니다:

            <summary>Solving Navigation Challenges with Rust</summary>
            <description>Two and a half years ago, I had a problem. My company, Stadia Maps, offered routing via an API, but the year was 2023, not 2003, and people expect to get real-time guidance through their route rather than look at a static map with lines and written directions.

Most of our users didn&#x27;t have a large budget to hire a team (or two!) of mobile engineers to build the navigation experience from the ground up. But they all wanted many of the same features: a map, a line showing where you need to go, some indication of where you are, and prompts when you need to do something. Every app adds their own &quot;special&quot; features, but the common base is surprisingly large. And there was no SDK or even set of common components to build on!

No such open-source SDK existed. There were a smattering of vendor-locked and semi-locked SDKs, but none of them were customizable enough to support unique use cases, like golf carts or public bus drivers. Open-source wasn&#x27;t just &quot;nice to have.&quot; It was a requirement for many of our users!

That&#x27;s when I decided to build Ferrostar, a next-generation navigation SDK. Building something that even our competitors could use was just the first controversial decision. The next (at the time) was the technical architecture. We decided to build all of the core decision logic in Rust, and share it among native frontends written in Swift, Kotlin, or whatever other language made the most sense for the platform.

This talk will cover the process that led to our decisions, the technical architecture we arrived at, and how it&#x27;s working so far. We&#x27;ll cover how we build shared libraries, where we draw API boundaries, how we test, and even how we enable extensions in native code (Swift, Kotlin, Java, etc.). You do not need to be a Rust developer to benefit from this talk. (In fact, none of the other core contributors had written a line of Rust before joining the project!). We&#x27;ll cover all layers from Rust all the way up to Swift, Kotlin, and even JavaScript.

Choosing to do a project like this that&#x27;s both open-source and sponsored by corporate developers has interesting tradeoffs too! Nearly every contributor working on Ferrostar has been able to do so on work time, and gets paid one way or another. So we&#x27;ll also discuss how we&#x27;ve managed the collaboration across stakeholders over the project: both what has worked well, and the areas for improvement. We hope this will start a valuable discussion among other open-source projects. With many companies abandoning open-source in favor of more restrictive &quot;source available&quot; licenses, we are at a critical juncture for open-source, and we hope we can add to the conversation by highlighting ways to FOSS truly work for everyone involved.</description>

            <summary>AI 글쓰기</summary>
            <description>1. 문제 제기: 우리는 왜 여전히 상용 도구에 의존하는가?
  * MS 워드, 아래아글에서의 코드 및 데이터 관리의 한계
  * 상용 통계 패키지의 비싼 라이선스 비용과 재현성 문제
  * Git을 이용한 체계적인 버전 관리의 어려움

2. 새로운 대안: Quarto 기반의 통합 글쓰기 환경
  * Quarto: 코드, 데이터 시각화, 텍스트를 하나의 문서로 통합하는 차세대 마크다운
  * R/Python: 문서 내에서 직접 실행하고 결과를 업데이트하는 재현 가능한 데이터 분석
  * LaTeX/Typst: 복잡한 수식과 전문적인 레이아웃을 위한 강력한 조판 시스템
  * Git: 모든 변경 이력을 추적하고 협업을 가능하게 하는 완벽한 버전 관리

3. 오픈소스와 AI의 결합, 그리고 실제 출판 경험
본 발표에서는 Quarto 기반의 글쓰기 환경에 AI 언어 모델(LLM)을 접목하여 글쓰기 워크플로우를 가속하는 방법을 구체적으로 다룹니다. AI를 활용해 초안 작성부터 R/Python, Mermaid 등 다양한 코드 생성까지 자동화하고, 이를 통해 생산성을 극대화하는 과정을 라이브 데모로 생생하게 보여드릴 예정입니다. 이러한 오픈소스 워크플로우의 가능성은 단순한 이론에 그치지 않으며, 실제로 한국 R 사용자회에서 개발한 오픈소스 출판 도구 &#x27;bitPublish&#x27;를 활용하여 완성한 결과물을 종이책과 전자책으로 성공적으로 출판한 경험을 공유합니다. 본 발표를 통해 참가자들은 오픈소스와 AI가 어떻게 우리의 문서 작성 문화를 혁신하고 있는지 조망하고, 자신의 프로젝트에 바로 적용할 수 있는 실질적인 팁과 리소스를 얻게 될 것입니다.

발표 대상
  * 상용 문서 도구의 한계를 느끼고 대안을 찾고 있는 개발자, 연구원, 학생
  * 데이터 분석과 문서 작성을 동시에 효율적으로 하고 싶은 데이터 과학자
  * 재현 가능한 연구(Reproducible Research)에 관심 있는 모든 분
  * 오픈소스와 AI를 활용한 생산성 향상에 관심 있는 분

예상 난이도
  * 초급 ~ 중급: 프로그래밍이나 데이터 분석에 대한 깊은 지식이 없어도 이해할 수 있도록 기본 개념부터 차근차근 설명합니다.</description>

            <summary>데비안 프로젝트 기여 고찰: A Study on Contributions to the Debian Project</summary>
            <description>데비안(Debian)은 운영체제다. GNU/Linux 커널을 기반으로 하면 리눅스 배포판이라 할 수 있고, GNU/Hurd 커널을 기반으로 하면 허드(Hurd) 배포판이라 할 수 있다.

동시에 데비안은 커뮤니티다. 자원봉사자로 이루어진 데비안 개발자, 메인테이너, 기여자들의 공동체다. 실제 데비안에서는 전통적인 개발 외에도 다양한 분야에서 기여가 필요하다. 문서화, 지역화(번역), 위키, 확산(언론), 인프라 운영(서버 관리자 등)과 같은 영역이 대표적이다. 이를 포괄하기 위해 데비안은 “Non-uploading 개발자”라는 개념을 마련했다. 이들의 기여는 기록되고, 공식적으로 데비안에 의해 인정된다.

그러나 작년 한국, 부경대에서 열린 DebConf24에서는 소외될 수 있는 사례가 드러났다. 온라인 기반의 기여는 비교적 쉽게 기록된다. 반면 2주간 오프라인에서 진행되는 컨퍼런스 주최 기여, 즉 On-site 중심의 기여는, 이를 기록하는 체계가 없다면 쉽게 누락된다. 짧은 기간 자원봉사에 참여한 경우는 기록되었으나, 오랜 시간 준비와 현장에서의 집중적인 기여가 요구되는 개최 활동은 기록되지 않고 잊히는 문제가 발생했다.

본 발표는 이러한 On-site Non-uploading 기여를 중심으로 데비안의 기여 문화를 고찰한다.

Debian is an operating system. When based on the GNU/Linux kernel, it is known as a Linux distribution; when based on the GNU/Hurd kernel, it is a Hurd distribution.

At the same time, Debian is also a community—a collective of volunteers including developers, maintainers, and contributors. In practice, Debian relies on contributions far beyond traditional software development. Areas such as documentation, localisation (translation), the wiki, publicity, and infrastructure maintenance (e.g. server administration) are all essential parts of the project. To recognise this diversity, Debian introduced the concept of &quot;Non-uploading Developers&quot;—contributors whose work does not involve uploading packages but is still officially recorded and acknowledged by Debian.

However, during DebConf24 held last year in South Korea, a form of contribution risked being overlooked. Online contributions are relatively easy to track and record, while on-site contributions—such as hosting and organising a two-week conference—can easily go unrecorded if no proper system exists. Short-term volunteer activities during the event were documented, but long-term, intensive on-site efforts in planning and execution were often omitted and forgotten.

This presentation explores Debian’s contribution culture, focusing on such on-site non-uploading contributions and the challenges of recognising them within the project’s current framework.</description>

            <description>현재 광운대학교 4학년에 재학하며, Theori에 재직중인 김성진이라고 합니다. 광운대학교의 LMS 시스템인 KLAS에 기능을 추가해주는 KLAS Helper 프로젝트에 2021년부터 참가하여 4년간 프로젝트의 메인테이너로 활동하고 있습니다. 이 외에도 수 많은 번역 프로젝트와, ImHex, Pillow, uftrace, 그누보드 등 크고 작은 프로젝트에 기여한 경험이 있습니다. 해당 발표에서는 KLAS Helper 프로젝트를 오픈소스로 운영하며 얻은 경험을 공유해보자 합니다.

먼저, 개인적/기술적 문제에 대해서 발표합니다. 단순한 학부생이였던 제가 KLAS Helper 프로젝트에 기여하는것을 시작으로 메인테이너의 업무까지 수행하게 된 경험을 공유하고, 프로젝트를 유지하며 기술적으로 생겼던 문제들에 대해 발표합니다.

다음으로, 비 개발자들의 커뮤니티 관리 경험에 대하여 공유합니다. 일반 학생분들과 소통하며 여러 이슈를 해결하고, 학교와 소통하면서 겪게된 이슈들, 그리고 이를 통해 얻어낸 경험과 노하우를 공유합니다.

마지막으로, ‘황혼기’에 접어든 프로젝트에서, 어떻게 사용자들의 참여를 유지하고 프로젝트를 계속 발전할 것인지에 대한 계획을 공유합니다.

해당 발표를 통해 많은 사람이 오픈소스에 더 관심을 갖고, 적극적으로 참여하는 계기가 되었으면 합니다.</description>

            <description>이번 발표에서는 발표자가 학생 시절 오픈소스 프로젝트인 리눅스 커널에 처음 기여하게 된 계기와 과정, 이후 개인적인 활동을 통해 커뮤니티 내에서 개발을 이어가며 배운 점, 그리고 회사 입사 후 업무 차원에서 왜, 그리고 어떻게 오픈소스에 기여하게 되었는지를 다룹니다. 이러한 과정을 통해 학생에서 개인 기여자, 그리고 전문 오픈소스 개발자로 발전해 나가는 여정 속에서 얻은 경험을 공유드리고자 합니다.

In this talk, the speaker will share how he first began contributing to the Linux kernel, an open-source project, during his student years, and how he continued to participate in the community through personal efforts afterward. He will also discuss why and how he started contributing to open source as part of his professional work after joining a company. Through this journey from a student to an independent contributor and finally to a professional open-source developer, he aims to share the experiences and lessons learned along the way.</description>

            <summary>The Hitchhiker&#x27;s Guide to Linux Kernel Contribution</summary>
            <description>The Linux kernel is one of the largest and most active open-source projects, but its massive codebase and unique development culture create a high barrier to entry for newcomers. While many guides focus on the technical methodology of sending the first patch (like using `git send-email`), beginners often feel lost about how to build expertise and contribute sustainably afterward.

I propose to present a beginner&#x27;s contribution guide focused on the Linux kernel security domain within the Operating Systems and Distributions track. This talk will be based on existing materials (e.g., LKCamp tutorials and DebConf etherpad notes) but will be enhanced with practical tips from my own experience in kernel security activities, reframing the discussion using the security subsystem as a case study for analysis and participation. The format will be a **Lightning Talk** covering how to overcome beginner hurdles, analysis methods, and engagement strategies, emphasizing the use of the **staging tree** and security-related **TODO lists**.

---

This presentation targets beginners who want to contribute to the Linux kernel but don&#x27;t know where to start, or those who are wondering about their next steps after their first contribution.

This session guides those new to Linux kernel development through the introductory process. It provides step-by-step explanations, from building foundational knowledge (C language, OS concepts, Git) and setting up the environment (email client, using the `checkpatch.pl` script), to analyzing unfamiliar subsystems (researching security papers/conference materials, tracking Git history), and making initial contributions (bug reports, code reviews, patch submissions). Drawing from my own experience starting with curiosity in the security domain, I will share tips on building expertise and emphasize practical strategies like monitoring mailing lists and leveraging conference materials (e.g., Linux Plumbers Conference). The content is designed to minimize the confusion beginners face and encourage an enjoyable journey.

**Part 1: The Hurdles Beginners Face (What Stops Us?)**
* **High Barrier to Entry:** The need for extensive background knowledge (OS, computer architecture) and the importance of patience.
* **Getting Used to the Kernel Environment:** Understanding fundamental kernel behaviors like execution context and synchronization mechanisms.
* **The First &quot;Real&quot; Contribution:**
    * Quick review of the development process documentation (Documentation/process).
    * Summary of technical procedures: using `checkpatch.pl`, `get_maintainer.pl`, and setting up `git send-email`.
    * The meaning and limitations of contributions like coding style fixes or working in `drivers/staging`.
* **&quot;Now What?&quot;:** The inevitable wandering after the first contribution. Shifting the perspective from &quot;What *should* I do?&quot; to &quot;What do I *want* to do?&quot;

**Part 2: How to Analyze an Unfamiliar Subsystem (Without Starting from Scratch)**
* **Design Before Code:** Understanding the subsystem&#x27;s purpose and the big picture first.
* **Efficient Research:** How to use kernel documentation, related academic papers, conference presentations (LPC, LSFMM), and technical blogs.
* **The Latest Code is Too Complex:** Strategies for reducing complexity during analysis.
* **The Power of History Tracking:** Starting with the simpler, initial versions of the code and following the git history and mailing list archives (lore.kernel.org) to understand the context of changes.

**Part 3: Contributing to Kernel Development is Not Just About Coding**
* **Diverse Roles in the Community:** Understanding different contribution methods (maintainer, reviewer, developer, bug reporter) and strategic positioning.
* **Benefits of Starting as a Reviewer:**
    * Learning the latest technical trends by reading others&#x27; code.
    * Code reviewers are always in short supply: A way to gain expertise while naturally contributing to the community.
* **Tracking Trends:** The importance of monitoring mailing lists, tips for using email clients efficiently (e.g., mutt), and leveraging news sites like LWN.net.

**Conclusion:**
* Enjoy the journey of kernel contribution.</description>

            <summary>Plain Text Accounting with hledger</summary>
            <description>Plain Text Accounting, 말 그대로 단순한 텍스트 파일 만으로 회계를 하는 것 입니다. 보통 회계 한다 생각하면 스프레드시트로 하거나, ERP 등 회계 프로그램을 활용하는것을 많이 생각하는데, 전자는 수작업이 많고 후자는 복잡하고 고정적인 비용이 발생하는 경우가 많죠. 

hledger, beancount 등 Plain Text Accounting 도구를 활용하면 명령줄을 기반으로 텍스트 파일에 기록하는 형태로 회계를 할 수 있습니다. 이를 통해 기본적인 회계 전표 입력을 조금이나마 편리하게 할 수도 있는 한편, 회계 장부 Git 등 활용한 버전 관리, 명령줄로 회계전표 입력이나 데이터 변환 자동화, CI 활용한 회계장부 검사와 리포팅 자동화 등도 가능한데요.

이 세션에서는 hledger 를 통해 어떻게 회계 관리를 하고, 앞서 언급한 회계 장부 관리와 보고서 생성 자동화 등이 가능한지, 실제 사례와 함께 공유 하고자 합니다.</description>

            <description>Accessibility isn&#x27;t separate from good Android development—it&#x27;s part of it. When we build with accessibility in mind from the start, our apps become more robust and our product elevates to the next level.
Let&#x27;s explore practical approaches to making Android apps accessible and how this work naturally improves your development practices. Also, with the European Accessibility Act (EAA) now in effect, understanding these principles isn&#x27;t just good practice—it&#x27;s becoming essential for many Android applications and the businesses behind them.</description>

            <description>Have you used Open WebUI before? It brings the power to connect to many LLMs through OpenAI&#x27;s inference API.

However, there are LLMs not compatible with OpenAI&#x27;s inference API. How would you deal with them?

Fortunately, there is an alternative, called **OpenChat Playground**. Regardless of your LLMs that are commercial or not, or OpenAI compatible or not, it can virtually connect any LLM.

Throughout this session, 1) I&#x27;d like to introduce the OpenChat Playground project, and 2) discuss how it&#x27;s possible to connect to virtually any LLM, and 3) how it can bring benefits to the open-source community.</description>

            <description>2017년 첫 커밋에서 시작된 식탁보(TableCloth) 프로젝트는 지난 4년간 기술과 운영 면에서 다양한 변화를 겪었습니다.
그 과정에서 변화의 물결 속에서도 끝까지 지켜온 핵심 가치가 있었습니다. 이번 세션에서는 프로젝트의 성장과 진화, 그리고 변하지 않은 철학을 함께 돌아보며, 장기 오픈 소스 프로젝트를 운영하는 데 필요한 통찰과 전략을 나누려 합니다.

The *TableCloth* project, which began with its first commit in 2017, has undergone a wide range of technical and operational changes over the past four years. Amidst these waves of change, there have been core values that have remained steadfast. In this session, we will reflect on the project’s growth and evolution, as well as the philosophy that has not changed, and share insights and strategies essential for sustaining long-term open-source projects.</description>

            <summary>How to collaborate on documents efficiently with ONLYOFFICE Docs?</summary>
            <description>Struggling with disjointed workflows, version control issues, and the limitations of your current document editors? This speech is your comprehensive guide to a more integrated and efficient solution. We will introduce you to ONLYOFFICE Docs, a powerful, open-source office suite built for seamless and secure collaboration from the ground up.

We will introduce each of ONLYOFFICE editors, showcasing their unique capabilities.

 • Document Editor: Go beyond basic word processing. We&#x27;ll explore advanced formatting, review tools with track changes and comment threads, and the ability to work with complex legal-style documents. Create, edit, and collaborate on DOCX, ODT, and PDF files with unparalleled fidelity.
 • Spreadsheet Editor: Tackle complex data analysis without compromise. Discover a full set of functions, pivot tables, charts, and data validation tools. We&#x27;ll demonstrate real-time co-editing on financial models and see how multiple users can work on different parts of a spreadsheet simultaneously.
 • Presentation Editor: Design and deliver impactful presentations together. This editor supports animations, transitions, and speaker notes, allowing teams to collaboratively build and refine their slide decks in PPTX and ODP formats, ensuring a unified visual identity.
 • PDF Editor: While primarily an editing suite, we&#x27;ll also highlight its robust PDF capabilities. View and edit PDFs natively and, uniquely, fill out PDF forms directly within the browser, eliminating the need for printing and scanning.

Beyond the features, we will detail the key advantages that make ONLYOFFICE Docs stand out.</description>

            <summary>LibreOffice 확장, H2O restart 의 개발 및 오픈소스 경험</summary>
            <description>개발 동기: Windows 환경에 종속된 한글 문서 변환 문제를 해결하기 위한 개인 프로젝트로 시작.
기술 구현: HWP/HWPX 파일 파싱, LibreOffice 확장 인터페이스 구현, UNO API 활용.
오픈소스 전환: 소스코드 공개 이후 사용자 증가, 버그 리포트 및 커뮤니티 기여 활성화.
기여 방법 안내: 버그 리포트, 코드 기여, 배포 패키지 관리, 홍보 활동 등 다양한 참여 방식 소개.
한계와 개선 방향: 완벽한 변환은 어렵지만, 사용자 피드백을 통해 지속적으로 품질 향상 중.

Motivation: Started as a personal project to overcome Windows-only limitations in HWP document conversion.
Technical Implementation: Parsing HWP/HWPX formats, building LibreOffice extension interfaces, using UNO APIs.
Open Source Transition: Public release led to increased users, bug reports, and active community involvement.
Ways to Contribute: Bug reporting, code contributions, Linux packaging, promotion and outreach.
Limitations &amp; Improvements: Perfect conversion is challenging, but ongoing feedback helps improve quality.</description>
