Hi 訂閱者,
2026，COSCUP 邁入第 21 年！今年我們將第一次攜手亞洲推廣 Ubuntu 的 UbuCon Asia，把來自臺灣、亞洲與世界各地的開源夥伴帶到臺北。
歡迎所有 Coder 開發者、User 使用者、Promoter 推廣者社群夥伴，把 8/8–9 保留下來！來老地方「台科大」，帶著開放的心與 Show Me Your Code / Idea 的衝動，和相信自由開放的夥伴交換觀點，展現這一年的成果！
裝備整理好你的經驗，一起上舞台
倒數三天！現在正是把你的分享慾送進 COSCUP 的絕佳時機，徵稿於 2026 年 5 月 9 日 AoE 截止。
我們歡迎技術展示、工具研究與技術分享，也歡迎開源商業導入、社群協作、文件在地化等多元議題。
不需要是社群、專案、公司或企業「完美無瑕」的故事。
只要你的經驗曾經幫你少走彎路，它也值得幫更多人少繞一圈。
立馬投稿 | 徵稿公告
AI、LLM 與資料應用：等你的經驗開放分享！
從 Twinkle AI 訓練資料、AI 開放治理、公民科技，到開放 LLM 底層技術與使用者經驗，都有你可以分享的方向。無論是 Agentic Coding、Vibe Coding、RAG、AI Agents、模型部署、資料集處理，或 AI 進入公共議題現場的觀察，都值得被更多人聽見。
把經驗帶進更複雜的現場：資安、韌性、商業
Hackers In Taiwan、網路韌性 / Cyber Resilience、開源商業模式 / Open Source Business Ecosystem，以及帶您讀源碼等議程軌，都在回應開源於現實世界中的挑戰。從資安風險、供應鏈安全、弱點處理，到企業如何採用開源、支持上游、面對授權、治理與維運挑戰，都很適合帶上 COSCUP。
老朋友與新知識都在等你：程式語言、開發者與系統技術
COSCUP 一直是開發者交流的重要場合。今年也有 Ruby Taiwan、System Software、JSDC x DevFrontier、JVM 台灣代表隊、Golang TW 及 Cloud Native、Taipei.py，以及 GDG TW 等議程軌。無論是語言升級、系統重構、開發現場的坑，或終於看見光的問題拆解，都是很好的分享題目。
把底層經驗說出來：資料庫、區塊鏈與基礎架構
MySQL、PostgreSQL 臺灣使用者社群，以及 Blockchain and Distributed Ledger 等議程軌，涵蓋資料庫、分散式系統與基礎架構相關經驗。從資料庫調校到分散式帳本、鏈上治理與維運，只要能讓其他技術團隊少踩一個坑，就值得被更多人聽見。
開源不只存在於螢幕裡：硬體、韌體、車用與電子紙
Open-EP、Software Defined Vehicle、Open Source Inspired Hardware，以及 Open Source Firmware 等議程軌，讓開源不只停留在軟體世界。電子紙、開放硬體、韌體開發、車用開源技術，或軟硬整合的經驗，這裡都是你的舞台。
讓開源進入真實世界：開放文化社群、在地化與公共議題
State of the Map Taiwan / Wikidata Community Summit、Fediverse & Social Web、開源政策、OSPN 日本、臺灣自由軟體在地化社群、農業開放資料社群、匿名網路社群 anoni.net 等議程軌，涵蓋開放文化與公共議題。維護在地化、整理開放資料、推動開源政策、經營社群、參與公共議題，或思考去中心化社群網路的經驗，都可以成為他人加入開源世界的入口。
如果你看了一圈，覺得自己的題目很重要，但不確定該放在哪一軌，別急著關掉投稿頁。COSCUP 也有綜合議程，歡迎 FLOSS、開放文化、開源合規、開源授權、開源職涯，或出國參與開源研討會的經驗談。
把你的經驗裝備整理好，一起上舞台吧。
也許你的一場分享，就是另一個人開始參與開源的起點！
用支持把舞台撐起來，一起推開源
除了投稿，我們也正在徵求贊助支持與合作。贊助方案除了各等級企業方案外，也新增 「贊助社群客製化方案」，讓支持企業不只贊助大會，也能將部分資源挹注合作社群，協助社群在 COSCUP 前後持續運作。
歡迎願意幫忙牽線的朋友與社群夥伴加入，讓支持不只是一次性的曝光，而是一個由志工、講者、社群與夥伴共同維運的開源公共舞台。
若你相信開源、相信分享，也相信交流能讓社群更強大，歡迎一起把這場年會撐起來。
期待在 COSCUP x UbuCon Asia 2026 不見不散！
COSCUP 2026 籌備團隊 敬上

Hi 訂閱者,
In 2026, COSCUP enters its 21st year! This year, for the first time, we are joining hands with UbuCon Asia, the event promoting Ubuntu across Asia, to bring open source contributors and communities from Taiwan, Asia, and around the world to Taipei.
We warmly invite all Coders, Users, Promoters, and community partners to save the dates: August 8–9. Come back to our familiar venue, National Taiwan University of Science and Technology, with an open mind and the urge to “Show Me Your Code / Idea.” Let’s exchange ideas with people who believe in freedom and openness, and share what we have built and learned over the past year.
Get Your Experience Ready and Step onto the Stage
Three days left! Now is the perfect time to send your ideas to COSCUP. The Call for Proposals is scheduled to close on May 9, 2026, AoE. We welcome technical demos, tool research, and engineering talks, as well as topics on open source business adoption, community collaboration, documentation localization, and many other areas.
Your story does not need to be a “perfect” story from a community, project, company, or enterprise.
If your experience has helped you avoid a detour, it is worth sharing so that others can avoid one too.
Submit your proposal Direct HERE! | Call for Proposals announcement
AI, LLMs, and Data Applications: Your Experience Is Waiting to Be Shared
From Twinkle AI training data, open AI governance, civic tech, to the underlying technologies and user experiences of open LLMs, there are many directions for you to explore. Whether your topic is Agentic Coding, Vibe Coding, RAG, AI Agents, model deployment, dataset processing, or observations from bringing AI into public-interest contexts, your experience deserves to be heard.
Bringing Experience into More Complex Fields: Security, Resilience, and Business
Tracks such as Hackers In Taiwan, Cyber Resilience, Open Source Business Ecosystem, and “帶您讀源碼” all respond to the challenges of open source in the real world. Topics such as cybersecurity risks, supply chain security, vulnerability handling, enterprise open source adoption, upstream contribution, licensing, governance, and maintenance challenges are all highly welcome at COSCUP.
Old Friends and New Knowledge Await: Programming Languages, Developers, and System Technologies
COSCUP has always been an important gathering place for developers. This year, we also have tracks from Ruby Taiwan, System Software, JSDC x DevFrontier, JVM 台灣代表隊, Golang TW and Cloud Native, Taipei.py, GDG TW, and more. Whether your topic is language upgrades, system refactoring, lessons learned from development work, or finally untangling a long-standing technical problem, it could be a great talk.
Share What Happens at the Foundation: Databases, Blockchain, and Infrastructure
Tracks from the MySQL and PostgreSQL Taiwan user communities, as well as Blockchain and Distributed Ledger, cover experiences related to databases, distributed systems, and infrastructure. From database tuning to distributed ledgers, on-chain governance, and operations, if your experience can help another technical team avoid even one pitfall, it is worth sharing.
Open Source Is Not Only on the Screen: Hardware, Firmware, Vehicles, and E-Paper
Tracks such as Open-EP, Software Defined Vehicle, Open Source Inspired Hardware, and Open Source Firmware show that open source is not limited to the software world. E-paper, open hardware, firmware development, automotive open source technologies, and software-hardware integration experiences all have a place on this stage.
Bringing Open Source into the Real World: Open Culture, Localization, and Public Issues
Tracks such as State of the Map Taiwan / Wikidata Community Summit, Fediverse & Social Web, Open Source Policy, OSPN Japan, Taiwan Free Software Localization Community, Agriculture Open Data Community, and the anonymous network community anoni.net cover open culture and public-interest topics. Experiences in localization, open data work, open source policy advocacy, community building, public participation, or decentralized social networks can all become entry points for others to join the open source world.
If you have looked through the tracks and feel that your topic is important, but are not sure where it belongs, do not close the submission page just yet. COSCUP also has a general track that welcomes talks on FLOSS, open culture, open source compliance, open source licensing, open source careers, and experiences from participating in open source conferences abroad.
Get your experience ready and step onto the stage with us.
Your talk might be the starting point for someone else’s journey into open source.
Support the Stage and Help Open Source Move Forward
In addition to the Call for Proposals, we are also seeking sponsorship and partnership support. Alongside our corporate sponsorship tiers, we are continuing the “customized community sponsorship package,” allowing supporters not only to sponsor the conference, but also to direct part of their support to partner communities, helping them continue their work before and after COSCUP.
We welcome friends and community partners who are willing to help make connections. Let support be more than one-time exposure. Let it become part of a shared open source public stage, sustained by volunteers, speakers, communities, and partners together.
If you believe in open source, in sharing, and in the power of exchange to strengthen communities, we warmly invite you to help us support this annual gathering.
We look forward to seeing you at COSCUP x UbuCon Asia 2026!
Sincerely,
The COSCUP 2026 Organizing Team
