EmulationStation is a graphical and themeable emulator front-end created by Aloshi around 2012. Their original work has been the foundation for the UX of many of our favorite gaming focused projects over the last decade and this document aims to capture a small bit of that history. If you see any errors please let me know in the comments below and I will gladly update this document.

Overview

How to configure FreeBSD and applicable applications to work with Yubikey for authentication. This serves as my work-in-progress documentation of the configuration knobs needed to make this work properly.

FreeBSD ssh with piv smartcard slot on Yubikey (pkcs11 via libykcs11.so)
FreeBSD ssh with fido support on Yubikey
FreeBSD Firefox/Chromium with fido + webauthn support on Yubikey
FreeBSD local console and gdm authentication using pam on Yubikey
FreeBSD official YubiKey tools

Latest Tested FreeBSD versions

Configuring the Digispark ATTINY85 board for Arduino IDE and upgrading the bootloader

Warning: this document has to be updated by pointing to https://github.com/SpenceKonde/ATTinyCore

This note describes the configuration of an ATtiny85 based microcontroller development board named Digispark and similar to the Arduino line. It is available in many online marketplaces for roughly 1 dollar (e.g., Ebay, Amazon, AliExpress) and is shipped fully assembled, including a V-USB interface (a software-only implementation of a low-speed USB device for Atmel's AVR microcontrollers). Coding is similar to Arduino: it uses the familiar Arduino IDE and is already provided with a ready-to-use bootloader (

I recently happened upon a very interesting implementation of popen() (different API, same idea) called popen-noshell using clone(2), and so I opened an issue requesting use of vfork(2) or posix_spawn() for portability. It turns out that on Linux there's an important advantage to using clone(2). I think I should capture the things I wrote there in a better place. A gist, a blog, whatever.

This is not a paper. I assume reader familiarity with fork() in particular and Unix in general, though, of course, I link to relevant wiki pages, so if the unfamiliar reader is willing to go down the rabbit hole, they should be able to come ou

Theming Slack for OSX

So, you love Slack, but you hate applications with large white backgrounds? Why not use Dark Mode!

Unfortunately, Slack does not have a Dark Mode, although it's on their list of possibilities.

But, don't fret - there is a solution! Because the slack native desktop apps are just wrappers around a web app, we can inject our own CSS to customize the application to our liking.

How to (OSX Only)

"Secret" Slack Slash Commands

Enable Web Inspector

/macgap.app.enabledevelopertools()

Assign a color (using hex code) to any users name

/color andrew #000000

Change Status (Doesn't seem to work)

/status
