thebigdatajedi / root_mean_square_error.py
Created May 17, 2022 11:27
#sklearn.metrics has a mean_squared_error function. The RMSE is just the square root of whatever it returns.
#source:https://intellipaat.com/community/1269/is-there-a-library-function-for-root-mean-square-error-rmse-in-python
from sklearn.metrics import mean_squared_error
from math import sqrt
rms = sqrt(mean_squared_error(y_actual, y_predicted))

thebigdatajedi / In Windows the .profile file if multiple vendors are using ssh keys using GitBash.sh
Created December 17, 2022 11:41
For a few months in the pandemic my Mac Book Pro would not ship because labor shortages, I was then given a Windows box for 6 months. And I quickly found out what I could do to use GitBase with a .profile file to use to Git vendors.
env=~/.ssh/agent.env
agent_load_env () { test -f "$env" && . "$env" >| /dev/null ; }
agent_start () {
(umask 077; ssh-agent >| "$env")
. "$env" >| /dev/null ; }

thebigdatajedi / reset hard.txt
Created December 17, 2022 11:45
This an explanation to what you get with git reset hard and how to do it. My bias is that if I'm having absolutely to do a reset this is the reset I do.
If you reset --hard, it will make your local code and local history be just like it was at that commit: <commit hash>
git reset --hard <commit hash>

thebigdatajedi / reset soft.txt
Created December 17, 2022 11:50
This an explanation of what git reset soft does and how to do it. My bias is to do a git reset hard. I usually have to do them when I'm in a terrible place and the loss of code will be code I wasn to get rid off, the thing with the git reset soft is that it leaves your local files etc. the same. I just don't have much use for moving the HEAD but…
And if you reset --soft, it will move your HEAD to where they were , but leave your local files etc. the same:
git reset --soft <commit hash>

if(nums[j] < nums[i]) {
//checking elements
temp = nums[i];
nums[i] = nums[j];

//if the condition is false>;
//Credit Union System example with evaluating fees.

return (isMember ? '$2.00' : '$10.00');
