downloading folders from google drive.

I wanted to download some course material on RL shared by the author via Google drive using the command line.  I got a bunch of stuff using wget a folder in google drive was a challenge. I looked it up in SO which gave me a hint but no solution. I installed gdown using pip and then used: gdown --folder --continue https://drive.google.com/drive/folders/1V9jAShWpccLvByv5S1DuOzo6GVvzd4LV if there are more than 50 files you need to use --remaining-ok and only get the first 50. In such a case its best to download using the folder using the UI and decompress locally. Decompressing from the command line created errors related to unicode but using the mac UI I decompressed without a glitch.

How to search your youtube history from the command line in ?

So I eventually found that the personal Youtube search url is at: https://myactivity.google.com/myactivity?q=query&restrict=ytw A nice ui no doubt but I need to get at from the command line... To avoid breaking the URI we must ensure the query text is url encoded so: urlencode() { # urlencode <string> local length="${#1}" for (( i = 0; i < length; i++ )); do local c="${1:i:1}" case $c in [a-zA-Z0-9.~_-]) printf "$c" ;; *) printf '%%%02X' "'$c" esac done } with that: #youtube history command yth(){ urlencode | google-chrome "https://myactivity.google.com/myactivity?q='${*//[$'\t\r\n ']}'&restrict=ytw" } p.s. all these go in a dotfile say at ~/Dotfiles/.functions and then sourced via: $source ~/Dotfiles/.functions so to look up the legendary session " Willy Wonka of Containers - Jessie ...

Random Thoughts on Linear Regressions

Regression Analysis TLDR Regression is the oldest and most powerful tool in a data scientist's toolbox. Under ideal conditions multiple linear regression would be the best and only tool a data scientist would want to use... In reality you would use a modern nonparametric variant or a different algorithm. Still, the main ideas I . discuss here  will pop up in many other models and algorithms. This post is my brain dump on regression - I'll update it as time allows to cover the many aspects of this technique.

SQL - Selection v.s. Projection

Selection and projection are two high level processes taking place when SQL queries are executed. Selection is choosing some records (rows) from a table and leaving others out. e.g. rows having name='oren'. Projection is the choosing some columns from each record and leaving others out. e.g. only name. So the select keyword performs projection while the where and keyword performs selection. Clearly the choice of using the keyword select for projection (choosing columns) rather than choosing rows, is an unfortunate flaw in the design of SQL, but this oversight is too well established to be fixed.
