26 September 2025 - Daily Drawing Day 269
#20252025Challenge
My chair at work is in the path of two cold air channels, which is not ideal. Today I tried placing a small fan facing one of them to see if I can redirect it over me. Surprisingly, it kinda worked (albeit not very well). I'll have to try with a bigger fan next time.

The 2025 20-25 Challenge.

This year let’s get better at something by finding a little practice time most days, in my case drawing. - Do your activity for at least 25 minutes, at least 25 days per month.
- Use the hashtag #20252025Challenge on social media etc to track your progress
- Also use the hashtag to cheer on others.

That’s about it!

Have fun with your activities, whatever they may be!

Drawing, programming, dancing, cooking, make up, reading, languages, gardening, mastering high fives, sewing, astrophysics, vcr clock setting ...

🌘 ASHRAE通風建議太低
➤ ASHRAE的通風建議可能導致CO2濃度超過2000ppm
cerereanscratchpad.blogspot.co
作者認為ASHRAE的通風建議太低,可能導致CO2濃度超過2000ppm,進而影響認知表現和健康。作者建議每人每秒通風量應為15 L/s,並指出這是一個值得支付的能源成本。
+ 這篇文章提供了有關通風建議的有用信息,讓我們更好地瞭解如何保持空氣質量。
+ 我希望ASHRAE能夠重新考慮他們的建議,以確保人們的健康和安全。

やっぱロティだよねー #通風
