   spindle disk. Returns true for an SSD and false for anything else.

.DESCRIPTION
   Use Get-PhysicalDisk to get the Physical Disk Ids for the system you wish
   to test. This script supports values being passed throught the pipeline.
   
   The methods used for detecting are by reading the Nominal Media Rotation

Comparison of npm scripts vs Gulp

npm scripts

Pros

• npm scripts are low-level and leverage the actual library you want to use (example: "lint": "eslint ./")
• package.json is a central place to see what scripts are available (also npm run will list all scripts)
• When things get too complicated you can always defer to another file (example: "complex-script": "babel-node tools/complex-script.js")
• npm scripts are more powerful than one might first think (pre/post hooks, passing arguments, config variables, chaining, piping, etc...)

to recover files that were added to the index but whose changes were lost (e.g. git reset --hard)

git fsck --unreachable | grep commit | cut -d\  -f3 | xargs git show

1. git fsck --unreachable to get all the items that are unreachable
2. grep commit to filter out all entries except for commits (the index will show up as a commit)
3. cut -d\ -f3 to filter out all but the SHA1s
4. xargs git show to show all of the contents of the objects.

Once you've identified the SHA1 that contains the changes that were lost, check it out to get the working tree back into the state of the index at the time git reset --hard was run.

Local and readonly variables in shells

I've no idea how shells implement them. In this article, I will pretend they use a stack based implementation.

Ksh93 never pops out values. When dash encounteres 'local', it just reuse the outer value. Bash and pdksh/mksh unset values first.

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>
