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.

The Happy winners #nlihack 2017

About the event  The happy winners! Amir Aharoi, Oren Bochman and Chaim Cohen Last week (November 23-24 2017) I had the pleasure of participating in the first  National Library of Israel's Hackathon . I've been to the NLI a few times with friends from the Wikimedia movement to instruct its staff and students about editing Wikipedia. But at the hackathon, the NLI opened its doors to the best and brightest minds to help out with tagging content and dissemination of its extensive image database. The Team You can't win a hackathon without a great team. My team consisted of seven developers which have been a part of the core community of Wikimedia developers in Israel and have been meeting irregularly since the International Wikimedia hackathon Organized by Wikimedia Israel last year in Israel.  We had met about a week before the event at the Local chapter's offices and discussed over pizza what we wanted to do and what the NLI had asked us to do. I realized that ...

A Tale of Two Hackathons

Image
Hackathon TLV 2013 (Photo credit: Wikimedia Israel ) It was the best of times ... when due to a generous grant from WM.NL I was able to participate in the 2013 Mediawiki hackathon in Amsterdam . Hackathons are amazing. Regular hackathons in TLV are highly competitive but open source hackathons are incredible. There are unbelievable  levels of energy in these events and opportunities to reach out to very large numbers of participants. When Hackathons include teaching sessions they reduce the learning curves associated with learning new technology - an ever increasing hurdle to participation in FLOSS projects. If the hackathon sessions are taped they can be easily edited and become a powerful method for transferring institutional knowledge locked in the minds of experienced contractors. Once these videos are released they can be combined with tutorials and used for self-instruction by new hackers. Hackathon TLV 2013 (Photo credit: Wikimedia Israel ) As the 21...

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.
