If you’ve got an interest in languages, writing, and computers – you may have stumbled into the crazy world of Shorthand and stenography. If you want to use shorthand from a regular keyboard, now’s your chance!

If you don’t use a Password Manager to store your login information for websites, first go read this: http://www.troyhunt.com/2011/03/only-secure-password-is-one-you-cant.html. I’ve been using KeePass for my password manager for years, but noticed that their Professional Edition had a pretty brutal startup delay. As in – launch KeePass and wait 80 seconds for the window to open. While password security is important, that kind of delay will make even the most security-conscious person start thinking about using ‘123456’ for their password instead.

You’ve probably been in the situation of wanting to alert yourself when any update happens to a sports game, UPS package tracking status, or something else. By combining Invoke-WebRequest’s beautiful support for HTML parsing with Send-MailMessage’s ability to send email messages - this becomes incredibly easy and useful. (Note: this script also uses Watch-Command, a script from the PowerShell Cookbook.) $content = "" while($true) { Watch-Command -ScriptBlock { ## Fetch the current box score for the game $r = Invoke-WebRequest http://www.

If you’ve tried to diff files in PowerShell before, you might have seen the Compare-Object cmdlet. The Compare-Object cmdlet lets you compare two sets of items, giving you a report on the differences between those two sets: PS G:\lee\tools> cd c:\temp PS C:\temp> $set1 = "A","B","C" PS C:\temp> $set2 = "C","D","E" PS C:\temp> Compare-Object $set1 $set2 InputObject SideIndicator ----------- ------------- D => E => A <= B <= From this output, we can see that “A” and “B” only show up in $set1, while “D” and “E” only show up in $set2.

If you’re interested in learning guitar, you might be running into an enormous feeling of dread. How do you get started? What kind of guitar should you get? Here’s a short guide that can hopefully help get you started. Buying a Guitar Guitars can get really expensive. But higher-end guitars end up being a matter of taste (both musically and aesthetically). For your first guitar, you don’t have an opinion, so there’s no need to splurge.

Have you ever wondered who’s in your “Email Social Network”? I was wondering the other day how to find out who I mail the most. With a bit of PowerShell scripting, the answer is a breeze to find out: ## Connect with Outlook, and open the 'Sent Items' $olApp = New-Object -com Outlook.Application $namespace = $olApp.GetNamespace("MAPI") $sentItems = $namespace.GetDefaultFolder(5) ## Go through each item, split out names when there were multiple ## recipients, and clean them up a bit $sentEverTo = $sentItems.

In the last post, I talked about how I used PowerShell to “STUN Roll” the open WiFi at DefCon. How much code was that? Was it hard? It turns out that it was pretty reasonable - less than 60 lines of PowerShell. ## Convert a string in the form of hexadecimal characters into the ## equivalent bytes. function ConvertFrom-HexString { param($HexString) $HexString -split "(..)" | ? { $_ } | % { [Convert]::ToByte($_, 16) } } ## Get the broadcast address for a subnet.

Every year, two of the biggest hacking / security conferences take place in Las Vegas: Black Hat, and DefCon. Both are great experiences, and both have a common theme – hackers (“Intelligent folks that like to make machines do things they weren’t originally designed for”) getting together to educate each other and have fun. Unsurprisingly, one of the places that people get together to have fun is the free open WiFi.

You might sometimes run into a situation where you’ve got a serialized object stream, and want to redact sensitive information out of that stream. For example, consider the following object: $objectToSerialize = [PSCustomObject] @{ Name = "Lee" SocialSecurityNumber = "SomeSecretNumber" Address = "1234 Something Road" GateCode = [PSCustomObject] @{ Prefix = 1234 Password = "SomeSecretPassword" } } In this, you want to remove any property value that says “SomeSecret”. PowerShell makes this fairly easy, since the PSObject special property on every type gives you access to an object’s methods and properties.

If you’ve seen the OutputType attribute when writing a cmdlet or advanced function, you might wonder what we use it for. The goal of the OutputType attribute is to provide a mechanism for tools to know what your cmdlets may output without running them. If they know that without running it, they can provide useful services – such as tab completion, data flow analysis, etc. For example: Get-Process | Where-Object { $_.
