Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

Hackathon Hackers Design Competition

View the submissions and vote!

HH and HH Design have teamed up to host the first Hackathon Hackers Design Competition!

The cover photo for Hackathon Hackers is OLD. Like ancient. Like it’s the same one uploaded the day this group was created. It’s time for an update.

The creativity of the hacker community knows no bounds. We’re hoping you can come up with cover photo concepts that capture the unique ethos of student hackathons. So take some time out of your holiday break, spin up your favorite image editor, and try your hand at branding HH.

The Scammiest Scam To Yet Anonymity Scam

I'm still holding out for this being a hoax, a big joke, and that they're going to cancel the kickstarter any minute. It'd be quite the cute "lessons learned" about anonymity scams. However, I will be treating it from here on out as a genuine scam. (As of May 2nd, the kickstarter has been cancelled, after the strangest attempt to reply to this imaginable. Good riddance.)

This absolutely ridiculous thing was brought to my attention by a friend and since it was late at night I thought I must be delirious in how absurdly over the top fake it seemed. So I slept on it, woke up, and found that it had gotten a thousand dollars more funding and was every bit as flabbergasting as I thought it was.

Since I realize that not everyone has spent their entire lives studying computers – and such people are the targets of such scams –

RSpec Style Guideline

Please follow this guideline to refine your rspec, make sure code is better after you modify anything

use `:type` and `Rspec` in declaration

RSpec.describe Api::UsersController, type: :controller do
	...
end

there are also some other types

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Async/Await for Swift

Proposal: SE-XXXX
Authors: Chris Lattner, Joe Groff

Introduction

Modern Cocoa development involves a lot of asynchronous programming using closures and completion handlers, but these APIs are hard to use. This gets particularly problematic when many asynchronous operations are used, error handling is required, or control flow between asynchronous calls gets complicated. This proposal describes a language extension to make this a lot more natural and less error prone.

This paper introduces a first class Coroutine model to Swift. Functions can opt into to being async, allowing the programmer to compose complex logic involving asynchronous operations, leaving the compiler in charge of producing the necessary closures and state machines to implement that logic.

	* This program implements a covert channel that can be used to transmit data
	* between two processes when run on the Apple Silicon "M1" CPUs.
	*
	* The channel is slightly lossy due to (presumably) the scheduler sometimes
	* scheduling us on the wrong CPU cluster, so this PoC sends every byte twice
	* together with some metadata/framing bits, which is usually good enough.
	* A better approach would be to use proper FEC or something like that.
