However, if you open the command line and you attempt to run “chrome.exe” it will complain that the executable is not found in the %PATH%

This is because Control+R also looks up the registry values within HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\

Which include all apps ever installed such as Chrome.exe, Firefox.exe, Excel.exe, Illustrator.exe, etc.

So if you are ever writing a program in your programming language of choice, using a Windows Registry check of the location (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths) for whatever.exe will be the perfect solution when that program is not in the System Environment variable %PATH%

API

• Postman: allows to share, test, document & monitor APIs.

IDE

• Visual Studio: Windows software development IDE (C#/WPF)
• Jetbrains Webstorm: Javascript IDE that becomes powerful with plugins (I use it for writing Go code)

Text editors

• Sublime Text (commercial) but lightweight and powerful
• Atom 
• Brackets

Must have tools

• Git (or Github Desktop or Git for Windows)
• Linux terminal/bash (available on any Mac/Linux machine, for Windows download Git for Windows linked above)

Some of these notes will tell you the exact code you would need to make a computer’s “224” to be outputted as “$224” or “224 %”.

using System;

class FormattingNumbers
{
static void Main()
{
decimal theDecNumber = 12345.678m; //the “m” creates a literal of type decimal from a double
//Using the ToString Method
//the number in the format string is the precision specifier
Console.WriteLine(“No formatting: ” + theDecNumber.ToString());
Console.WriteLine(“Currency formatting: ” + theDecNumber.ToString(“C”));
Console.WriteLine(“Exponential formatting: ” + theDecNumber.ToString(“E”));
Console.WriteLine(“Fixed-point formatting: ” + theDecNumber.ToString(“F2”));
Console.WriteLine(“General formatting: ” + theDecNumber.ToString(“G”));
Console.WriteLine(“Number formatting to 2 decimal places: ” + theDecNumber.ToString(“N2”));
Console.WriteLine(“Number formatting to 3 decimal places: ” + theDecNumber.ToString(“N3”));
Console.WriteLine(“Number formatting to 4 decimal places: ” + theDecNumber.ToString(“N4”));
Console.WriteLine(“Percent formatting: ” + theDecNumber.ToString(“P0”));

int theIntNumber = 123456;
Console.WriteLine(“Hexidecimal formatting (for integers): {0} = {1}”, theIntNumber, theIntNumber.ToString(“X”));

double theDblNumber = 1234567890;
Console.WriteLine(“Custom formatting: {0} to US telephone {1}”, theDblNumber, theDblNumber.ToString( “(###) ### – ####” ));

//Keep console open if not run through command prompt
Console.Write(“\nPress Enter to Continue”);
Console.ReadLine();
}
}

John Sheehan has some very good tips and information on his blog. For archive purposes I have mirrored his .NET cheatsheet (download link here). Hope this helps you.
