Interesting - I may have hyperphantasia? Most of my thoughts are accompanied by images, and I can rotate and unfold things. It's so vivid I seem to have two types of synesthesia: https://en.wikipedia.org/wiki/

Nothing is "secure or not" - technologies/mitigations are secure against particular attacks. HTTPS is generally secure against passive network eavesdropping, but does nothing to stop local file inclusion in a web app. Just be

Hmmm, well that's why I like Ruby and other languages with functional approaches. Method chaining and blocks are very similar to pipes to me. cat /etc/passwd | grep root | awk -F: '{print $3}' ruby -e &#x

The only reason I have any vague understanding of this article is all thanks to PBS Space Time on Youtube. It's an amazing series. Must watch if you want to know how much we humans understand about our universe.

I've found that stevia sweeteners with inulin (not insulin) seen to be beneficial for my gut bacteria. Actually seems to help with "loose days". Sweetleaf is generally what I use.

Funny, I love Ruby and it's my primary language of choice, but I'm a heretic, using braces whenever I can: # events per day ndbh.fetch('select ts from tbl').all.map { |row| row[:ts] }.map { |t|

Seems to me the main difference is that all the particles in the gyro are trying to go in a straight line, but can't due to being a part of a rigid structure. You should be able to tell the difference by dropping a ball bearing. It wil
