Performance improvements for bulk import

I implemented for my own use case - not fully tested - use at your own risk

This is how I improved performance of django-import-export when importing a large set of new rows.

• Thinkpad T470 i5 processor (Ubuntu 18.04)
• 20,000 new rows to be inserted
• total import duration 5.4 seconds

This is a proposal for ReactiveConf 2017 open call for Lightning talks. If you'd like to make this talk happen, please 🌟 this gist and retweet my tweet. 🙏

If you're on your phone, please request the 🖥 desktop site to star this gist 😇

I would talk about some myths on Jest & Enzyme. Moreover to stop the comparison of Jest and Enzyme. Instead would focus on how they can work together to test well your React Components. The talk would focus on "How Jest and Enzyme complement each other" and can help you test React components in a better way.

1. If you are writing tests: you are already winning.
2. If you are not writing tests:let me encourage you to start.
3. Jest.
4. Snapshot Testing.

A top-down look into Elixir (for Rubyists)

• Phoenix (as "Rails for Elixir")
  • Rails and Phoenix can get suspiciously similar
  • A code sample:
• controller.rb

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Google Apps Script pdfToText Utility#

This is a helper function that will convert a given PDF file blob into text, as well as offering options to save the original PDF, intermediate Google Doc, and/or final plain text files. Additionally, the language used for Optical Character Recognition (OCR) may be specified, defaulting to 'en' (English).

Note: Updated 12 May 2015 due to deprecation of DocsList. Thanks to Bruce McPherson for the getDriveFolderFromPath() utility.

    // Start with a Blob object
    var blob = gmailAttchment.getAs(MimeType.PDF);
