Very long shot: At the 2015 there was a food stand that made apple fritters (Apfelkrapfen). The people were really nice and the Krapfen were really good.
Unfortunately, I didn't get a name and I haven't seen them at any other event since. Does anyone know them and maybe if they still operate? :BoostOK:

「冰浴」到底好不好?科學揭曉冷水療法的利與弊

近年冰浴(cold plunge)蔚為風潮,無論健身族、運動員還是追求健康生活的人,都爭相體驗這種極冷療法。其實早在古埃及、希波克拉底時期,人們就已認識冷水帶來的療癒效果。但冰浴究竟對健康有何幫助?科學實證又怎麼說? 所謂冰浴,指的是將身體浸泡於攝氏約7至15度(華氏45至59度)的冰水中,時間從30秒到數分鐘不等。專家建議新手從短時間、較高水溫(如攝氏13-16度)開始,逐步延長至3-5分鐘即可,且不需追求極低溫,以免危及健康。患有心臟病、高血壓或心律不整者則應避免。 冰浴主要帶來三大生理變化。首先,冷水刺激交感神經,釋放腎上腺素、多巴胺等「快樂激素」,提升心情與專注力。其次,冷水收縮血管,促進血液循環;回到常溫後血管擴張,有助於緩解肌肉疲勞。第三,寒冷引發顫抖,短暫提升代謝率,理論上有助於燃脂減重,但現有證據有限。 恐暫時降低爆發力與抑制肌肉增生 運動員常用冰浴加速恢復。2025年一項匯整11項臨床研究的系統性回顧發現,冰浴對即時壓力減緩效果有限,但12小時後參與者感覺壓力降低、睡眠品質與生活滿意度提升。另一篇2023年分析運動員的研究則發現,冰浴有助於運動後減緩肌肉痠痛與疲勞,但可能暫時降低爆發力。需注意的是,若在重量訓練後馬上冰浴,可能抑制肌肉增生,專家建議間隔4至6小時後再進行。 總結來說,冰浴對身心健康有一定助益,但不適合每個人。專家提醒:「享受其中就好,不舒服或身體無法適應時應立即停止。」科學支持冰浴能改善睡眠、緩解壓力與恢復肌力,但並非萬靈丹,安全與適度最重要。 更多科學與科技新聞都可以直接上 明日科學網  http://www.tomorrowsci.com 首圖來源:whitebalance.space / Getty Images (CC BY 4.0)  圖片來源:Plumb Images/Leicester City FC via Getty Images (CC BY 4.0)  參考論文:1、Throwing cold water on muscle growth: A systematic review with meta-analysis of the effects of postexercise cold water immersion on resistance training-induced hypertrophy Europen Journal of SportScience 延伸閱讀:1、洗臉也有步驟?冷水比熱水更好?洗臉訣竅全公開 Total 0 Shares 分享 0 Tweet 0 Pin it 0 Share 0

개인적으로는 바니 샌더스(83세), 무라카미 하루키(76세), 사카모토 류이치(향년 71세), 그리고 유시민 (65세), 진중권 (62세), 조국 (60세) 이 사람들 나이 보면서 1) 내가 늙었을 때 어느 정도의 지적 활력을 유지할 수 있는가. 2) 두각을 나타낸 젊은이가 나이를 먹었을 때 성숙함은 어떤 방향이 되는가. 3) 나이를 먹는다고 사람의 생각이 반드시 보수화, 더 나아가서 극우화가 되고 기득권에 영합하게 되는가. 라는 화두를 갖게 되었음.

Shout out to those personal fitness tracker things.

I hit the fatigue wall early last night and despite having lots of energy in the morning, I was knocked out by early evening.

This morning my brain says, "you need to move more and do all the things today because you were so sedentary last night. Don't be lazy!"

Fitbit says, "several of these markers are outside of your usual range. You may not feel like it but you should rest because your body needs to recover."

This thing on my wrist has given me permission to rest!

I know, I know, I'm going to need to switch to a proper LSP integration at some point (among other reasons, the owner of this repo apparently hasn't even logged into github in like 3 years, it seems plausible that it will never be updated again) but I am still excited that I got to stop gaslighting me about my code by finally figuring out what was causing this extremely confusing behavior github.com/tkf/emacs-jedi/issu

New blog post! 🥳

How I like to install NixOS (declaratively)

For one of my network storage PC builds, I was looking for an alternative to Flatcar Container Linux and tried out NixOS again (after an almost 10 year break). There are many ways to install NixOS, and in this article I will outline how I like to install NixOS on physical hardware or virtual machines: over the network and fully declaratively.

@lcamtuflcamtuf :verified: :verified: :verified: @nothacking Especially when you consider that both decimals and fractions are representation, and this isn't the only case where we use a simplified, but "good enough" version of an irrational number.

I think this is also a case where people are picking up a subtle communication issue when dealing with the numbers. If I write "9/9", I mean "Broken into nine parts, and we have all nine.". If I write "0.99999999...", I'm far more likely to mean "We're juuuuuuust under 1"
