Did you know that OS X has dtrace running on it?! I didn’t.
Choosing a WordPress Vagrant Box
I want a Vagrant box on which to configure and develop WordPress. Here are some of the options. I wanted to decide on one. Here is how.
- Box: name
- Stars: on GitHub, # stars
- Ctrb: on GitHub, # contributors
- Rel: on GitHub, # releases
- Cmts: on GitHub, # commits
- Brn: on GitHub, # branches
- For: Purpose of box
- Rct: Gut reaction 1
+: Like*: Pros and Cons-: Dislike
- Rt2: Gut reaction 2
Strategy:
- Identify options
- Classify them by stars and contributors
- Get a gut reaction whether to dig deeper or not
- Review them again
| Box | Stars | Ctrb | Rel | Cmts | Brn | For | Rct | Rt2 |

Where VMWare Fusion Stores Boxes on OSX
When you create VMWare Fusion virtual machines through the GUI they are stored in ~/Virtual Machines.
When Vagrant creates VMWare Fusion virtual machines they are stored in Vagrant-file-directory/.vagrant/machines/default/vmware_fusion.
Confirmed it myself.
Thank you JT Gray.
Correctly Setting the VMWare Provider for Vagrant on Windows
When you purchase the VMWare provider for Vagrant on Windows you learn that the provider name is vmware_desktop. The only time that you will ever use this name is when you install the provider and the license. If you use that provider name anywhere else you will get message
The provider ‘vmware_desktop’ could not be found, but was requested to back the machine ‘default’. Please use a provider that exists.
The correct provider name is vmware_workstation.
You might mix up the two names when specify a provider when you are bringing a box up. I did it. He did it. It is easy to do, especially if you scan a box page to find the provider name. The name there is for the name to install the license, not to start up a box.
This “issue” has been around for over a year and wastes about an hour of your time if you are facing it on Windows.
Windows Azure: The Big Picture
Windows Azure: The Big Picture.
You won’t view anything in this video and say “Oh my goodness I never imagined you could do that with a computer”. What will happen though is that now you will know how Azure lets you do that with a computer, all of their offerings from virtualization to networking to message queues covered. That is great to know. I chose this video specifically because it is the shortest. Further digging is required.
The Case for PowerShell
The Case for PowerShell.
Brief, terse, compact, too many jokes. Excellent details. Not training, rather informational. Must have scripting/automation experience to appreciate the implications of what is covered. Without that experience, the presentation could be viewed as too light-weight.
IIS for Developers
IIS for Developers.
Brief, terse, compact. Excellent details required to deploy a system to IIS. Not training, rather informational. Must have server/system-deploy experience, and therefore questions, before viewing.
Lightweight DevOps
Introducing DevOps to your organization can be done really, really simply.
First have the project team lead set up the development environment on his machine, all the while documenting how to do so. Second have a another team member follow and execute the steps. The lead and team member should discuss and review the process and make improvement. Third, have an engineer totally unfamiliar with the project follow the steps to the point where he can successfully run the automated tests in less than sixty minutes.
When this may be done successfully, it is time for a DevOps engineer to automate that process.
