AppleScript and JavaScript for Automation to get frontmost tab’s url and title of various browsers.
-- AppleScript --
-- This example is meant as a simple starting point to show how to get the information in the simplest available way.
-- Keep in mind that when asking for a `return` after another, only the first one will be output.
-- This method is as good as its JXA counterpart.
-- Webkit variants include "Safari", "Webkit", "Orion".
-- Specific editions are valid, including "Safari Technology Preview".
-- "Safari" Example:
tell application "Safari" to return name of front document

iOS Core Animation: Advanced Techniques, Part 1: The Layer Beneath

Author: https://www.cyanhall.com/

1. The Layer Tree

Core Animation's original name is Layer Kit

Core Animation is a compositing engine; its job is to compose different pieces of visual content on the screen, and to do so as fast as possible. The content in question is divided into individual layers stored in a hierarchy known as the layer tree. This tree forms the underpinning for all of UIKit, and for everything that you see on the screen in an iOS application.

In UIView, tasks such as rendering, layout and animation are all managed by a Core Animation class called CALayer. The only major feature of UIView that isn’t handled by CALayer is user interaction.

There are four hierarchies, each performing a different role:

Zoom out to fit all annotations on MapView

I search a lot of questions and answers in SO. This is what i figure out. The result I want is map can zoom out to fit all/some annotations INCLUDE user's location.

The basic steps are:

  • Calculate the min lat/long
  • Calculate the max lat/long
  • Create CLLocation objects for these two points
  • Calculate distance between points
  • Create region using center point between points and distance converted to degrees

Mac Network Commands Cheat Sheet

Disclaimer: I'm not the original author of this sheet, but can't recall where I found it. If you know the author, please let me know so I give the attribution.

The original author seems to be Charles Edge, here's the original content, as pointed out by @percisely.

Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can.

Mac Network Commands Cheat Sheet

After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and s

How to install Zsh version 5.6.2 into CentOS 7

Given that you have a clean installation of CentOS 7 which was already updated, by you, then you still have some dependencies to install make and install the external Zsh from the source. You must be root to get the stuff done.

Install GCC Development Tools

yum groupinstall "Development tools"
