How to deal with JWT expiration?

First of all, please note that token expiration and revoking are two different things.

  1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
  2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

The code in this gist isn't as succinct as I'd like it to be. Please bare with me and ask plenty of questions that you may have about it.

VGG-16 pre-trained model for Keras

##VGG16 model for Keras

This is the Keras model of the 16-layer network used by the VGG team in the ILSVRC-2014 competition.

It has been obtained by directly converting the Caffe model provived by the authors.

Details about the network architecture can be found in the following arXiv paper:

Very Deep Convolutional Networks for Large-Scale Image Recognition

Why I'm Not A JavaScript Developer

Answering the Front-end developer JavaScript interview questions to the best of my ability.

  • Explain event delegation

Sometimes you need to delegate events to things.

  • Explain how this works in JavaScript

This references the object or "thing" defined elsewhere. It's like "hey, thing I defined elsewhere, I'm talkin' to you."

  • Explain how prototypal inheritance works.
