Use Python to add a file's modification time to the front of the file name

# Add a file's modified time to the front of the name of the file in the format

# YYYY-MM-DD-<original-filenam>.

# Works for files in the current directory.


from os import listdir

from os.path import isfile, join

import os

import time


mypath = "."

onlyfiles = [f for f in listdir(mypath) if isfile(join(mypath, f))]


for file in onlyfiles:

  newname = time.strftime('%Y-%m-%d-', time.gmtime(os.path.getmtime(file))) + file

  print("Renaming file: " + file + " to: " newname)

  os.rename(file, time.strftime('%Y-%m-%d-', time.gmtime(os.path.getmtime(file))) + file)

How to make an HTTP request with PowerShell

If you are making an HTTP request to a RESTful web service, you can use the PowerShell  Invoke-RestMethod cmdlet. This provides a very simple HTTP REST interface, and will also format the result into a PowerShell object. If you would like to use your own functions, you can follow the instructions below. This is a helper function to format (indent) an XML response from a web service. function Format-XML { Param ([string]$xml) $out = New-Object System.IO.StringWriter $Doc=New-Object system.xml.xmlDataDocument $doc.LoadXml($xml) $writer=New-Object system.xml.xmltextwriter($out) $writer.Formatting = [System.xml.formatting]::Indented $doc.WriteContentTo($writer) $writer.Flush() $out.flush() Write-Output $out.ToString() } Here is the function to make the http call.

A simple IIS HTTP module to log request headers and post data

This is a simple http module that hijacks the incoming request and logs it to a file. Using this module prevents the application from getting the post data because the input stream can only be read once. With .NET 4.0 the module could be much smaller, and could allow the application to read the data. To compile this, create a new "Class Library" application called PostDataLogger. Most of this class is pieced together from stolen code (stack overflow, etc.) using System; using System.IO; using System.Web; /// /// Dump PostDataLogger.DLL in your bin, and put this in your web.config inside of /// /// /// /// public class SimpleLogger : IHttpModule { private HttpApplication _ctx; public void Init(HttpApplication context) { _ctx = context; context.BeginRequest += new EventHandler(Context_BeginRequest); } void Context_BeginRequest(object sender, EventArgs e) { string GUID = Guid.NewGuid().ToString(); string filename = @"d:\temp\adeber...
