JSC

JSC is the JavaScript engine from Apple's JavaScriptCore (WebKit) as a console application that you can use to run script in the terminal.

For more info visit the JSC's webkit wiki page.

Adding a shortcut to JSC

Using jsc is simple, the one issue is that Apple keeps changing the location for jsc. To deal with this issue I just create a symbolic link to the binary:

Setting up ssh public key authentication on macOS using a YubiKey 4

I largely followed Florin's blog post, but have a few notes to add regarding issues I encountered:

Basic setup notes

I used a YubiKey 4, while the blog describes using a YubiKey NEO. I'm sure a YubiKey 5 would also work. I'm also running macOS 10.13.6.
I installed GPGTools as recommended. However, as I'll note later, it seems that gpg-agent only automatically starts when gpg is used; for ssh, you'll need to ensure it's running.
Before generating your keys, decide what key size you want to use. If you run the list command inside gpg --edit-card, look for the Key attributes line to see what is currently selected. On my YubiKey 4, it defaulted to 2048 bits for all keys:

Key attributes ...: rsa2048 rsa2048 rsa2048

How To Make A Working TWRP Device Tree For Your MediaTek Device & Start Building Them, Online

This Guide is tested on 64-bit mt6735/53 chipset device. It will also work on any 64-bit and 32-bit devices.

You will need something from your Stock ROM first. Get them all and Try to modify it using the procedure.

Note: This guide will be helpful for you if you have older mediatek devices (android-5.1 or android-6.0), but up-to-date devices can also work.

Update: This guide had a few typos and derps (Oops..), but I've tried to make it free of those now (Dated November 18, 2020)

Bonus: You can also use this tool by @SebaUbuntu, @yshalsager and @mauronofrio to auto generate the twrp tree. The tool is best if your device runs on android-9.0. The tools is still not 100% compatible to all devices, but I'll still recommend it and give it 8.5/10 in the scale of varsatility.

iOS Shared Cache Extraction

Having fallen off the iOS-exploration train due to completing my Masters and other commitments, I have finally climbed back aboard in pursuit of understanding the telephony stack.

Like most things in iOS that are used frequently, the vast majority of the frameworks and libraries used in the telephony stack reside in the DYLD shared cache located at /System/Library/Caches/com.apple.dyld/dyld_shared_cache_armv7.

In this post I am going to explain how to go about extracting this cache file so that you can then work with each library individually.

Get The Cache

The first step in all of this is to copy the cache over to your local machine. I did this using a program called iExplorer, but you can just as easily do it over SSH. As a side note, you can connect to your iDevice using SSH over USB if you install a tool called iProxy.

	- Move to the start of the line using fn + ← and to the end of the line with fn + →.
	- Also you can delete a word backwards using Option ⌥ + ⌫, delete the whole line using Command ⌘ + ⌫.

	If the preset doesn't appear, reinstall iTerm2. If you installed it using Homebrew + Cask:

	brew cask reinstall iterm2
