A curated list of AWS resources to prepare for the AWS Certifications

A curated list of awesome AWS resources you need to prepare for the all 5 AWS Certifications. This gist will include: open source repos, blogs & blogposts, ebooks, PDF, whitepapers, video courses, free lecture, slides, sample test and many other resources.

By the way, I'm available for tutoring and code review :)

What Promises library should I use?
How do I create a Promise myself?
How do I use new Promise?
How do I resolve a Promise?
But what if I want to resolve a synchronous result or error?
[But what if it's at the start of a chain, and I'm not in a .then callback yet?](https://gist.github.com/joepie91/4c3a10629a4263a522e3bc4839a28c83#6-but

OverEncrypt

This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.

WARNING: if you mess up settings, lose your certificates, or decide to no longer maintain HTTPS certs, these steps can and will make your domain inaccessible.

I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.

The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).

1. Model-loading function name changes

Rationale: Indicate type of model being loaded more explicitly in code.

For models converted from Keras and models saved from TensorFlow.js itself:

// Before: 
await tf.loadModel('http://server/model.json');
