The Importance of Spatial Reasoning in Early Childhood Mathematics – I find this interesting because of the above article about allergic tendencies mentions that those who suffer severe allergies have increased spatial reasoning which makes you better at mathematics. I have super severe allergies and math has always been a boring repetitive exercise. I have lots of Math books. I learn and understand math immediately. Algebra was boring, physics was just applied algebra same with Geometry. I only do math when I need to and often just review what I need to get the problem solved.

New study reveals why some people are more creative than others – I read about creativity because I am insanely creative, to the point I can’t stop daydreaming. When I am not doing something super complex that requires complex thinking I go into imagination land and the world around me disappears and I make huge messes as I solve problems like how does gravity work, or how to manipulate matter and create new atoms. I really want to learn about math, chemistry and physics, my brain is insanely creative. I have a severe form of ADHD and one of the highest IQ’s ever measured.

New to node and need to install npm, node.js? Use NVM node version manager so you can install more than one version of nodejs.
I had to look for the answer to this until I found it. You update to a newer version of NVM node version manager the same way you install it regardless of how you install it. I am not sure what happens if you install nvm with curl then try to update it in another way.
For example I used the following in my terminal as not the root user, just a plain user
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
When I want to install the next version I replace the v0.35.3 with the next version and it does all the work. If you installed nvm as a root user then you will not be able to access it easily as any other user.
In fact, if you type nvm –version in the command line as a regular user after you installed it as a root user, you will be told it is not installed, or nvm is not a recognized command would you like to install. I did this, so that is how I learned not to install it as a root user.
Never ever, ever, not ever use sudo when installing node, npm, nvm or anything like yarn it totally fucks every last thing up.
If you accidentally use sudo follow these instructions to fix the bowl of mashed spaghetti you end up with.

If you are using windows you can install nvm by following these instructions
