Part I: Algebraic Structures & Topological Foundations

Group

• Analogy: Like a dance routine: steps can be combined, there's a neutral pose, and every move has an undo.
• Joke: Why did the group go to therapy? It had identity issues.
• Definition: A set $G$ with operation $*$ satisfying associativity, identity, and inverses.

Setup Persistent Aliases & Macros in Windows Command Prompt (cmd.exe) using DOSKey

Saved from Archive.org, Date: May 14, 2010 Author: Jesse Webb

Our development machines here at Point2 are not standardized; we have a mixture of Windows XP, 7, and Mac OSX/Unix computers. I find myself constantly switching back and forth between command prompt interfaces when pair programming. As a result, I catch myself using “ls” to list a directories contents regardless of what system I am on. I am currently using a Windows XP machine for my developer box and I wanted to setup an alias to the “ls” command to actually perform a “dir”. Here is how I accomplished it…

There is a command available in a Window’s shell that let’s you “alias” command to whatever you please: DOSKey. It allows you to create “macros” to execute one or more other commands with a custom nam

Pre-requisite: go to http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html download http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe and http://the.earth.li/~sgtatham/putty/latest/x86/puttygen.exe

Run puttygen and generate the key

1. Click 'Generate' move the mouse around as instructed and wait

"Help, I keep getting a 'Permission Denied (publickey)' error when I push!"

This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:

1. Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any *nix based command prompt (but not the default Windows Command Prompt!)
2. Type cd ~/.ssh. This will take you to the root directory for Git (Likely C:\Users\[YOUR-USER-NAME]\.ssh\ on Windows)
3. Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Type ls to see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be named id_rsa and id_rsa.pub in order for Git, GitHub, and BitBucket to recognize them by default.
4. To create the SSH keys, type ssh-keygen -t rsa -C "your_email@example.com". Th
