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.

Data Science Glossary - H

Hadoop
An Apache open source project for batched calculation using the Mapreduce paradigm
Hit
was the smallest unit of work counted in a web server log. In modern analytics this now refers to the smallest units being measured though not all will register in a web server's log. These include page views, events, interactions with a social network, ecommerce transactions or even peed diagnostics.
Heat Map
an exploratory analysis technique with false color visualization for understanding website user interaction with ui at an aggregate . See also (HotJar, Crazy egg)
Hierarchical Clustering
is a clustering technique which includes multilevel clustering. There are two approaches to hierarchical clustering, agglomerative which starts from leafs and divisive.which starts from a root cluster.
Heterogeneity
market segmentation, whose motto is "one size does not fit all," relies almost exclusively on one definition of what constitutes a segment are groupings of objects such that similar objects are gathered together and separated from dissimilar gatherings of other similar objects. "Birds of a feather flock together" and stay away from birds of a different feather. (See also Homogeneity)
Homogeneity
web analytics by default will provide a view of users that is homogeneous. Most users fail to realise that this is not a useful view of the customers. (See also Heterogeneity)

Moodle <=< Mediawiki SUL integration - first thoughts

SUL is  Wikipedia's  Single User Login system The goal is to use it to authenticate moodle users there is one caveat - what happen if  the moodle user has no account. Moodle and MediaWiki account creation require different information. Since we'd like to use MediaWiki's standard which is highly permissive. It is necessary to change  moodle's requirements. Challenges Moodle does not explicitly define an object for setting registration requirements.  This needs to be accomplished by admins via edit a number of files manually.  errors will place the users in a limbo/blocked state... This is implemented differently on different version of moodle. This will break if the changes are overwritten by a system is upgrade. Directions Ideally Moodle should have a registration policy  object which allows the admin to define which fields are required and if they need to be unique . For example Moodle complains if different users share an email adr

Insight into progressive web apps

Some notes from a Meetup on PWAs in January 2016. I feel quite knowledgable on PWA but I wanted to learn more on implementing service worker. I ended up adding some research and collecting some great resources. However I ended up getting more detailed materials on the service worker based on google's developers docs. Also the resources have been expanded. https://www.meetup.com/The-Future-is-Javascript/events/246346861/ Service worker Service Workers Its just a simple JavaScript file that sits between you and the network – It runs in another thread – It has no access to DOM – It intercepts every network request (including cross domain) Entry point: self.caches (in service worker) or window.caches (on page)   Registering a Service Worker • Works with promises • Re-registration works fine In main.js navigator.serviceWorker.register('/sw.js').then(function(reg){ console.log('regsitered'); }.cat
