P2V on Apple Silicon - Converting a Physical Apple Silicon MacBook to a Virtual Machine on another Apple Silicon device (M1, M2, M3) on Apple's Virtualization Framework

Outline: Having recently bought a MacBook Pro (M3 Max) to replace my MacBook Air (M2), I decided it would be a good idea to start fresh and reinstall everything on my new Mac. However, I always like to keep a backup of my old data, so I thought it would be a good idea to virtualize my old machine on my new machine. Having much previous experience working with Windows P2V's (Physical to Virtual), I figured it would be as simple as Clone, Copy, Restore, and Boot. However, with the advent of Apple's new Signed System Volume, as well as the differences in file systems, APFS containers, and all, this ended up being a project that took about 2 days of nonstop researching, debugging, when I expected it to be a project which would last as long as it would take to clone my drive. I was very wrong. However, with all of my newfound knowledge in this s

Solarized Dark profile for Terminal.app on macOS High Sierra

Installation

Open and save Solarized Dark.terminal.

Import from the “Profiles” tab in the settings of Terminal.app or just double-click the file after downloading.

Your blockchain must have all of the following properties:

It's a merkle tree, or a construct with equivalent properties.
There is no single point of trust or authority; nodes are operated by different parties.
Multiple 'forks' of the blockchain may exist - that is, nodes may disagree on what the full sequence of blocks looks like.
In the case of such a fork, there must exist a deterministic consensus algorithm of some sort to decide what the "real" blockchain looks like (ie. which fork is "correct").
The consensus algorithm must be executable with only the information contained in the blockchain (or its forks), and no external input (eg. no decisionmaking from a centralized 'trust node').

If your blockchain is missing any of the above properties, it is not a blockchain, it is just a ledger.

Prerequisites : the letsencrypt CLI tool

This method allows your to generate and renew your Lets Encrypt certificates with 1 command. This is easily automatable to renew each 60 days, as advised.

You need nginx to answer on port 80 on all the domains you want a certificate for. Then you need to serve the challenge used by letsencrypt on /.well-known/acme-challenge. Then we invoke the letsencrypt command, telling the tool to write the challenge files in the directory we used as a root in the nginx configuration.

I redirect all HTTP requests on HTTPS, so my nginx config looks like :

server {

What's this about?

OS X 10.11, aka El Capitan, comes with a new system font for Chinese users, named PingFang, it includes 6 weights for both Simplified and Traditional Chinese. The same font also appear on iOS 9 as the default UI font, though Apple didn't mention it explicitly.

How to get it?

If you are in Apple Developer Program (costs 99 USD a year), then you can get them now at their developer resource site, otherwise you can wait for their public beta to come out in July or wait for the public release this fall (a free upgrade like previous release).

Or you can get PingFang.ttc from your developer friends, though you are probably violating its font license one way or another, but I am not a lawyer so freedom to you.

Webdriver PHP API workthough

Open a browser

# start an instance of firefox with selenium-webdriver

$browser_type = 'firefox'
$host = 'http://localhost:4444/wd/hub'

$capabilities = array(\WebDriverCapabilityType::BROWSER_NAME => $browser_type);

	def closepage(sender):
	v.close()

	def function_1(sender):
	v['label1'].text = 'Oh! You clicked my button.'

	#v = ui.MainView(frame=(0, 0, 600, 450)) # kivy
