Get ClamAV running on Mac OS X (using Homebrew)

The easiest way to get the ClamAV package is using Homebrew

$ brew install clamav

Before trying to start the clamd process, you'll need a copy of the ClamAV databases.

Create a freshclam.conf file and configure as so

Install `osxfuse` (3.x.x) from https://github.com/osxfuse/osxfuse/releases.

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Update Homebrew formulae:

brew update

How to add an Istanbul code coverage badge to your GitHub repository

This post has moved to my personal blog: http://maximilianschmitt.me/posts/istanbul-code-coverage-badge-github/

Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."

Stealth Addresses, Transactions and Messages

Normal bitcoin addresses cannot be published in public without losing all privacy, since all transactions to that address can be seen by anybody. Stealth addresses let us publish an address in public which can be used by payers to derive a new address that the payee has access to, but no one else knows is associated with the stealth address. The trick is that the payer must use a nonce to derive the address paid to, and this nonce must be delivered to the payee so they know how to recover the funds. This nonce can be delivered in the transaction, so that no separate channel is required to communicate the nonce.

The same technology can also be used to construct new public keys to send encrypted messages to.

We will discuss four methods:

The simplest form of stealth addresses, which has some drawbacks that can improved upon.
