-- 1. Create a new generic password entry in Keychain Access called "WHATEVER_AnyConnect_VPN" (the name in Keychain access must match that in line 39 below) with your password for the Cisco AnyConnect VPN server.  
-- 2. Open this script in Script Editor (both this and the above are in the Applications->Utilities folder) and "Save as.." an Application (.app) with desired name.
-- 3. Open Security & Privacy System Preferences, go to Privacy, Accessibility.
-- 4. Enable the above .app so it can access Accessibility
-- 5. Copy and paste a nice icon on the generic Applescript icon (I used a copy of the default AnyConnect one)
-- 6. Add the new .app to /Users/[yourshortname]/Applications with a shortcut to your Dock 
-- 7. Enjoy the fast connection with no need to enter password and increased security of not having a sensitive password stored as plain text
-- 8. Run script again to close connection

-- AnyConnect now refered to as targetApp

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Exposing your clipboard over SSH

I frequently administer remote servers over SSH, and need to copy data to my clipboard. If the text I want to copy all fits on one screen, then I simply select it with my mouse and press CMD-C, which asks relies on m y terminal emulator (xterm2) to throw it to the clipboard.

This isn't practical for larger texts, like when I want to copy the whole contents of a file.

If I had been editing large-file.txt locally, I could easily copy its contents by using the pbcopy command:

How to passthrough SATA drives directly on VMWare EXSI 6.5 as RDMs

There aren't many tutorials about this, the only tutorials I've found were about passing through entire PCIe cards to VMs, or refered to old ESXI versions (below 6.5) that used a more comprehensive desktop client instead of the web app. In v6.5, the web app was introduced and the desktop client was deprecated. You used to be able to setup RDMs in the desktop client, but with the introduction of the web console, this is no longer the case. This tutorial shows you how to pass SATA HDDs to the virtual machine on VMWare ESXI 6.5. This tutorial is partially based on VMWare's own KB and the now deprecated Forza IT blog post.

Summary

We attach the SATA HDDs as a RDM (Raw Device Mapper) into an existing virtual disk in the command line, then on the web app
