Django Channels on AWS Elastic Beanstalk using an ALB

This post will describe how to set up a Django Channels solution using AWS Elastic Beanstalk [EB]. This guide is written in response to there being very little information on the combination of Channels and AWS. Mainly many solutions end with problems regarding websockets, which is a fundamental part of Channels. See here and here. This guide will consist of multiple step-by-step parts including

• How to set up a local Django Channels solution
• How to set up an Application Load Balancer [ALB] to serve websockets
• How to configure EB to deploy Cha

A step-by-step guide how to use Python with Tor and Privoxy

Tested on Ubuntu 24.04 Docker container. The Dockerfile is a single line FROM ubuntu:24.04. Alternatively, you can simply run docker run -it ubuntu:24.04 bash.

NOTE: stopping services didn't work for me for some reason. That's why there is kill $(pidof <service name>) after each failed service <service name> stop to kill it.

Two Fast Methods of Generating True Random Numbers on the Arduino

Arduino true random number generator

B. Peng

December 2017

Abstract

The AVR series microcontrollers are a collection of cheap and versatile chips that are used in many applications ranging from hobbist projects to commercial infrastructure. One major problem for some hobbists is the lack of secure random number generation on the Arduino platform. The included pseudo-random number generator (PRNG) is very easy to defeat and is useless for any crypto-related uses. One recommendation from the Arduino Reference Manual is to use atmospheric noise from the chip's analog sensor pins as seed data^[6].
Unfortunately this method is extremely weak and should not be used to emulate a true random number generator (TRNG). Existing methods such as using the internal timer drift or using a dedicated generator are either too slow, requires extensive external hardware or modifications to the microcontroller's internal mech
