Every once in a while you will encounter a site that does some obfuscation.
I bumped into yet another base 62 encoded JavaScript, and this is what I used to unpack it:
This tool will help you decrypting the javascript encrypted with base 62 packer like the sample one on the box (eval(function(p,a,c,k,e,r){blah blah blah})
Just put the encrypted codes on the box then push the decrypt button…

Switching between many different languages, I tend to forget the exact names and symbols of the PowerShell operators.
Most of the ones I use have to do with comparison and logic, o here they are:
| Operator | Description |
|---|---|
| -eq | Equal to |
| -lt | Less than |
| -gt | Greater than |
| -ge | Greater than or Eqaul to |
| -le | Less than or equal to |
| -ne | Not equal to |
| Operator | Description |
|---|---|
| -not | Not |
| ! | Not |
| -and | And |
| -or | Or |
I find it funny that you have ! and -not, but not -!. Oh well (:
Talking about logicals: PowerShell can coerce a couple of values to $false, but I’m ambivalent to use that: it does shorten code, but is very PowerShell specific.
Before I forget: an operator that is undervalued, is the -f operator that does formatting.
It uses the standard .NET formatting strings, so that is an easy way to put your .NET knowledge to use. Some further reading on the -f operator:

Somehow I always forget this:
The PowerShell escape character is the backtick “`” character.
Use it for escaping quotes within quotes, or inserting special characters.
Don’t abuse it (see the great debate: do not use it as a line continuation).
Often you can avoid line continuation characters by using splatting, which is one of the “best kept secrets” in PowerShell.

Wow, I totally missed the introduction of SETX.
From TechNet:
SETX:
Creates or modifies environment variables in the user or system environment, without requiring programming or scripting. The Setx command also retrieves the values of registry keys and writes them to text files.
Even better, is that it allows you take values from these sources so it is easy to get those into environment variables:
From a bit of searching around, I think it got introduced in a Windows Resource Kit, and got included by default starting Windows Vista.
Excellent addition to my toolset (:

Thanks Robert Gamble, ephemient and Jonathan Leffler. Be sure to read the top two answers and comments for full details.
Until now, I always used $* to pass on arguments from *nux shells (bash, sh, ash, etc.). Works on ESXi as well. But that is not the correct way to do.
But “$@” is the correct way:
- Use “$@” to represent all the arguments:
for var in "$@"
do
echo "$var"
done
- As a shortcut,
for var; do ...; donemeansfor var in "$@"; do ...; done- Basic thesis: “$@” is correct, and $* (unquoted) is almost always wrong. This is because “$@” works fine when arguments contain spaces, and works the same as $* when they don’t. In some circumstances, “$*” is OK too, but “$@” usually (but not always) works in the same places. Unquoted, $@ and $* are equivalent (and almost always wrong).
This next to the following construct makes file processing in *nix a breeze:
for filename in *.7z; do if 7za t $filename 2>&1 > /dev/null; then echo $filename passed; else echo $filename failed; fi; done

Every once in a while, the local synchronization of offline files mismatches the actual files.
Time for a CSC reset.
Note: you need to be Local Administrator on the machin in order to reset the CSC cache.
Use Reg.exe
You can also automate the process of setting this registry value by using the Reg.exe command line editor. To do this, type the following command in the Reg.exe window:
REG.EXE. REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\NetCache" /v FormatDatabase /t REG_DWORD /d 1 /f

As a follow up on my recent rsync on ESXi 5.1 post, as – when rsync in ESXi terminates the hard way because of a lost SSH connection – rsync can leave “hidden” files behind.
A small script that recursively shows the hidden files (those starting with a dot) starting from the current directory:
find . -iname ".*"
More of those (including deleting them, filtering for only files or only directories, etc) are at Linux / UNIX: Bash Find And Delete All Hidden Files Directories.
Note: don’t try to outsmart using something like piping through grep "\/\." as that will also match files who’s parent directories are hidden.
