mastodon 4.7.3COSCUP is an annual conference held by Taiwanese Open source community participants since 2006.
今日活動將照常進行。
受颱風影響，目前有強風及豪雨。志工已在現場巡視場地，並針對強風進行加強防護。請大家前往會場及活動期間務必注意自身安全！
Today’s event will proceed as scheduled.
Due to the typhoon, we are currently experiencing strong winds and heavy rain. Our volunteers are already on site checking the venue and taking additional precautions against the strong winds. Please take extra care when traveling to the venue and during the event.
If you have umbrellas, rain gear, or luggage that you would like to leave somewhere, you can bring them to TR413-2.
After months of behind-the-scenes preparation, we’re excited to finally share the complete conference schedule with everyone. Check out the sessions and start planning your very own COSCUP journey!

We had an amazing time at @fossasia@floss.social last year, and earlier this year, many of the friends we met at our booth asked, “Are you coming again this year?” The answer is a definite yes! 😊
See you at @fossasia@floss.social in Bangkok on March 9–10 🤚
We are soooo happy to meet you at #FOSSASIA 2026! There is only one day left, come and chat with us tomorrow :) looking forward to seeing you all! 💖
In the upcoming #FOSDEM talk, Date Huang

Let’s join Yuyuan and the team as they share their design choices, performance tweaks, and unique features!

不知道大家有沒有注意到，這幾年 @COSCUP@floss.social 和 OCF 的夥伴們，總是結伴前往 @fosdem@fosstodon.org 擺攤與參訪
一起向國際社群介紹台灣的開源活動，也積極尋找各種合作的可能性 🤝
不過，你知道嗎？其實 OCF 的起源，和 COSCUP 也有著深厚的淵源！
在籌辦研討會的過程中，沒有法人身分往往寸步難行。
當年，社群夥伴們決定成立一個基金會，來協助處理這些現實卻關鍵的問題時，COSCUP 便與其他社群一起湊出啟動資金，共同成立了 開放文化基金會（Culture Foundation, OCF）
自此之後，OCF 承擔起許多帳務與法律相關的工作，並與社群一同討論、找出解決方案，讓我們能夠放心地把心力投入在更多真正想做的事情上
時至今日，@OCF1989@liker.social 所支援的社群與專案已越來越多，逐漸成為台灣開源社群最穩固的後盾 🌱
如果你曾參與 COSCUP 或是其他開源活動，歡迎一起捐款支持 OCF，成為支持他們、也支持台灣開源社群持續前進的一份力量 💪
