Change default shell

Editing /etc/passwd won't work in iOS, so in order to change default shell in iOS you need to edit /etc/master.passwd. You can change root's default shell to bash like this -- root:/smx7MYTQIi2M:0:0::0:0:System Administrator:/var/root:/bin/bash.

Reference

• changing default shell on iPhone
• /etc/master.passwd

// To check if a number is between a range, don't do
if number >=0 && number <= 100 {

}
// Use range and news operators instead :
if 0...100 ~= number {

Apple Real Devices Debugging

What you need

• certificate--which tells your devices that Apple trust you
• a app id
• a test device
• a provisioning profile

# You must first install apktool (https://github.com/iBotPeaches/Apktool) and android SDK
# and decompile apk using it 
# apktool d -rf my-app.apk

# then generate a key for sign in:
# keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
rm signed-app.apk
apktool b -f -d com.myapp

File Magic Numbers

Magic numbers are the first bits of a file which uniquely identify the type of file. This makes programming easier because complicated file structures need not be searched in order to identify the file type.

For example, a jpeg file starts with ffd8 ffe0 0010 4a46 4946 0001 0101 0047 ......JFIF.....G ffd8 shows that it's a JPEG file, and ffe0 identify a JFIF type structure. There is an ascii encoding of "JFIF" which comes after a length code, but that is not necessary in order to identify the file. The first 4 bytes do that uniquely.

This gives an ongoing list of file-type magic numbers.
