Pets vs Cattle

This refers to the pets versus cattle analogy for IT

The analogy concisely describes a major paradigm shift in our industry that we have been implementing with BAM2.

An elevator pitch for “Pets vs Cattle” from “The History of Pets vs Cattle and How to Use the Analogy Properly
In the old way of doing things, we treat our servers like pets, for example Bob the mail server. If Bob goes down, it’s all hands on deck. The CEO can’t get his email and it’s the end of the world. In the new way, servers are numbered, like cattle in a herd. For example, www001 to www100. When one server goes down, it’s taken out back, shot, and replaced on the line.

"4 Reasons Why “Pets Versus Cattle” Still Matters in Cloud Security"
This slide is taken from a presentation given by Gavin McCance at CERN in 2012. Though, The Register identifies Microsoft’s Bill Baker as the original source of this analogy.

Setting Beyond Compare as the default diff tool in Sourcetree

When you right click on a file that has changed in the Unstaged file panel of Sourcetree, you have an "External Diff" option. This post indicates that Sourcetree uses "whatever you have configured in your .gitconfig already as your default diff tool"

You can set Beyond Compare as your default diff tool by following the instructions posted here.

At a Windows command prompt, enter the commands:
  git config --global diff.tool bc
  git config --global difftool.bc.path "c:/Program Files (x86)/Beyond Compare 4/bcomp.exe"

Note: For Git versions older than 2.2 (git --version) replace "bc" with "bc3" in the above instructions.

3-way Merge Pro only

At a Windows command prompt, enter the commands:
  git config --global merge.tool bc
  git config --global mergetool.bc.path "c:/Program Files (x86)/Beyond Compare 4/bcomp.exe"

Note: For Git versions older than 2.2.0 (git --version) replace "bc" with "bc3" in the above instructions.

Launching Diffs and Merges

File Diff:
  git difftool filename.ext
Folder Diff:
  git difftool --dir-diff
3-way Merge:
  git mergetool filename.txt

Advanced Settings

To disable the "Launch 'bc3' [Y/n]?" prompt, run the command:
  git config --global difftool.prompt false
Git's default settings retain merge files with *.orig extensions after a successful merge.  To disable this safety feature and automatically delete *.orig files after a merge, run the command:
  git config --global mergetool.keepBackup false

Running the following command will open your .gitconfig file in an editor.
git config --edit --global

You will be able to see what the command did to edit your .gitconfig file.

Chromecast devices no longer discoverable after adding Mesh wifi point

Following is what I posted in the Chromecast support forum
I just bought a "NIGHTHAWK® MESH WIFI 6 SYSTEM (MK62)
When I am near the satellite, I cannot cast my screen to the Chromecast that is also near the satellite.  
If I walk to the front of the house, I get connected to the router base. I can always connect to the Chromecast at the back of the house. I can leave my phone at the front of the house and walk back and see my screen being mirrored.  
For the Chromecast we have upstairs in the front of the house, it always connects. I have not had an instance where I could not mirror my screen or cast from an app.  
I switched the two Chromecasts a few days ago. I experienced the same results based on the location they are at in the house. It has nothing to do with the Chromecast units. It is being caused by being connected to the satellite NightHawk unit.  
I went to and searched for NetGear. I disabled UPnP and enabled IPv6. My configuration does not seem to allow me to disable the 5GHz WiFi.  
I am beginning to think that this router will soon be listed as not compatible with Chromecast.  
Will a Nest Mesh WiFi work? Has anyone had a similar setup and gotten Chromecast to work when connected to a Nest satellite access point?
