The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Overview

The Sierra MC7355 can run configurations for several North American carriers. These cards are easy to find on eBay and notable for their support for the Sprint LTE network. Unless you're luck out, you may find you need to flash a new carrier configuration onto the card you purchased before using it.

Notes

These procedures are specific to the setup I had to perform this on. Most notably, the only system I had with a mini-PCI-e slot was the target pfSense system, a PCengines APU1d with no VGA port (serial console only). If you're able to obtain a

Scaling your API with rate limiters

The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.

In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.

Request rate limiter

This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.

:: Windows 10 Hardening Script
:: This is based mostly on my own personal research and testing. My objective is to secure/harden Windows 10 as much as possible while not impacting usability at all. (Think being able to run on this computer's of family members so secure them but not increase the chances of them having to call you to troubleshoot something related to it later on). References for virtually all settings can be found at the bottom. Just before the references section, you will always find several security settings commented out as they could lead to compatibility issues in common consumer setups but they're worth considering.

Overly aggressive CFS

We're looking at CPU bandwidth control via CFS:

Reproduction program

Program does number of iterations, in each iteration we burn CPU in small chunks until we get 5ms of real time spent. On each iteration we also print how much

Python zipapp web apps

What's a zipapp?

This concept is very much like .jar or .war archives in Java.

NOTE: The built .pyz zipapp can run on both Python 2 & 3 but you can only build .pyz zipapps with Python 3.5 or later.
