OpenWRT adblock implementation

Others have recently developed packages for this same functionality, and done it better than anything I could do. Use the packages instead of this script:

Description

In its basic usage, this script will modify the router such that blocked addresses are null routed and unreachable. Since the address blocklist is full of advertising, malware, and tracking servers, this setup is generally a good thing. In addition, the router will update the blocklist weekly. However, the blocking is leaky, so do not expect everything to be blocked.

How to setup Ngrok with a self-signed SSL cert

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

Migrate Redis data on Amazon ElastiCache
"""
Copies all keys from the source Redis host to the destination Redis host.
Useful to migrate Redis instances where commands like SLAVEOF and MIGRATE are
restricted (e.g. on Amazon ElastiCache).
The script scans through the keyspace of the given database number and uses
a pipeline of DUMP and RESTORE commands to migrate the keys.
Requires Redis 2.8.0 or higher.

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.
