Okay, Thanksgiving day Turf deep dive. Let's do this.

The problem: a refactored Turf relies on tree shaking to make it possible to include subsections of the module without including the whole thing. But tree shaking isn't working.

Approach

Remove indirection

We bundle from ES6 import/export modules into a single module bundle. Instead, set module: 'src/index.js' to remove a potential problem - Rollup bundling.

I observed that dtstart.dt datetime objects were aware (not naive).
There was no need to identify oldtz. Original author's comments left below.

A way to explain PGP (and/or public key crypto more broadly) using a hotel/apartment metaphor.

This is a draft!

Please give feedback, especially where the description is confusing or breaks the mental model of a hotel/apartment setup. As written, this is mean for fellow digisec trainers to leverage in their explanations, and is not (yet) a document to help people learning PGP by themselves.

There are a ton of ways people have described PGP in specific and public key cryptography more generally - from mixing paint (http://gizmodo.com/5888567/how-to-understand-encryption-using-paint-and-clocks, http://maths.straylight.co.uk/archives/108) to magic lock-boxes and Romeo and Juliet (https://www.level-up.cc/leading-trainings/training-curriculum/activity/love-story). I present another, which uses the experience of a hotel (or, alternatively, apartment buildings with front desk staff) as an analogy which can stretch to cover not just cryptography, but also digital signatures. This is written to explain PGP, but could be adapted for S/MIME and other public key crypto approaches.

We are always looking for great Data Scientists. If you can solve any of these [using open software], you'll be heads down helping us from day one. Email us to brunosanchez@worldbank.org

We are building an open stack to process nightly data from satellite and query light output from all known villages. Currently we are doing 20 years of nightly data for 600,000 villages in India.

/* Twitter API 1.1 tweets / favorites (likes) / following / followers backup in web browser
* Get your access keys to use Twitter API 1.1: https://dev.twitter.com/docs/auth/tokens-devtwittercom
* You can change Twitter API URL and Twitter screen_name, then execute script from a trusted web page without CSP protection like about:blank in a web browser console (F12 or Ctrl+Shift+K shortcut)
* A textarea will appear so you can copy/paste to save data as a CSV file or search tweets / users in your web browser (Ctrl+F shortcut)
* You can then view your backup in a spreadsheet editor like LibreOffice Calc
* You can also compare the backup with another one to see who unfollowed you, who changed their Twitter username by looking at the user ID or which tweet you retweeted / favorited was deleted (e.g. with the Linux diff command)
*
* Note about the tweets backup:
* Usually you will search tweets that you retweeted using Twitter web version (https://twitter.com/search) with a search like "from:your_username f
