Go SSH reverse tunnel implementation (SSH -R)
/*
Go-Language implementation of an SSH Reverse Tunnel, the equivalent of below SSH command:
ssh -R 8080:127.0.0.1:8080 operatore@146.148.22.123
which opens a tunnel between the two endpoints and permit to exchange information on this direction:
server:8080 -----> client:8080

A Few Useful Things to Know about Machine Learning

The paper presents some key lessons and "folk wisdom" that machine learning researchers and practitioners have learnt from experience and which are hard to find in textbooks.

1. Learning = Representation + Evaluation + Optimization

All machine learning algorithms have three components:

  • Representation for a learner is the set if classifiers/functions that can be possibly learnt. This set is called hypothesis space. If a function is not in hypothesis space, it can not be learnt.
  • Evaluation function tells how good the machine learning model is.
  • Optimisation is the method to search for the most optimal learning model.

Compile and deploy React Native Android app of Release version to device.
Disclaimer: The instructions are the collective efforts from a few places online.
Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.
First off, bundle.
==================
1. cd to the project directory
2. Start the react-native packager if not started
3. Download the bundle to the asset folder:
curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
