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.

Fixing Multi language support in Moodle

Image
Last week I was asked by +Charles Matthews  to review WM.UK upcoming Wikipedia tutoring system being developed on on the open source Moodle system. I've been thinking of different option to better support Wikipedia coaching in different languages  I have been reviewing and testing Moodle in the last few weeks to that end. I'm really interested in developing course ware for both English and Hebrew editions (as a start). Multilingual content While Moddle is internationalized, support of multilingual content requires using a somewhat clumsy technique. One need to use html and store different languages content in top level div elements. Then you have to switch on Moodle's multilingual filter which can hide all the language version which are incompatible with the language selector's settings. However due to a bug the the html editor mangles the html code and mangles the top level <span...

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.
