javisantana··on Why we maintain a ClickHouse fork at Tinybird (and how it's different)
Not going to disclose that but you can make a guess on % if you analyze the S3 write/read ops a ClickHouse server does with regular or compact parts in a simple table (with a few columns) writing once per second

javisantana··on Is Dark Mode Such a Good Idea?
Dark mode is very useful for people with "eye problems", for example, eye floaters are small black points you see all the time, they usually appear with the age, dark mode make them "disapear" making you brain happier.

Thanks whoever started dark mode trend
