Native Secure Enclaved backed ssh keys on MacOS

Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Zig type system illustrated using ascii diagrams

Zig Type System

Zig aims to be a simple language. It is not easy to define what simple exactly means, but zig is also a low-level programming language that aims for c-compatibility. To reach this goal, it needs good semantics in its type system so that developers have a complete toolbox to manipulate data.

So types in zig are composable, but this can become rapidly overwhelming. See those examples. Are you able to understand them at a glance, as soon as you read them?

Lightning Fast WordPress: Caddy+Varnish+PHP-FPM

README

This gist assumes you are migrating an existing site for www.example.com — ideally WordPress — to a new server — ideally Ubuntu Server 16.04 LTS — and wish to enable HTTP/2 (backwards compatibile with HTTP/1.1) with always-on HTTPS, caching, compression, and more. Although these instructions are geared towards WordPress, they should be trivially extensible to other PHP frameworks, other FastCGI backends, and even non-FastCGI backends (using proxy in lieu of fastcgi in the terminal Caddyfile stanza).

Quickstart: Use your own naked and canonical domain names instead of example.com and www.example.com and customize the Caddyfile and VCL provided in this gist to your preferences!

These instructions target Varnish Cache 4.1, PHP-FPM 7.0, and Caddy 0.10. (I'm using MariaDB 10.1 as well, but that's not relevant to this guide.)
