Command Line

Mounting shared drives and connecting to remote resources is something you can easily do from the Windows GUI. With our quick guide to the command prompt, however, you can more easily automate large tasks.
Quick super fast course in using the command line. It is intended to be done rapidly in about a day or two, and not meant to teach you advanced shell usage.

WGET

Using PowerShell (Among other useful options listed at this resource.):
WinWGet is a GUI (Graphical User Interface) for Wget. It is FREE. It will keep track of your downloads - add, clone, edit, delete jobs.
GNU Wget is a free network utility to retrieve files from the World Wide Web using HTTP and FTP, the two most widely used Internet protocols. It works non-interactively, thus enabling work in the background, after having logged off.
Say you want to backup your blog or create a local copy of an entire directory of a web site for archiving or reading later. The command: wget -m http://website.tld
Tips for mirroring specific directories, update only changed files, etc.
Download files using curl or wget. This addon generates curl/wget commands that emulate the request as though it's coming from your browser allowing you to download protected files directly to a separate machine (e.g. server).

Windows Command Line

Cmdlets are the heart-and-soul of Windows PowerShell, Microsoft's latest command shell/scripting language.
Robocopy: A robust file copy command for the Windows command line.
Each command is linked to more info about the particular command.
The xcopy command is a Command Prompt command used to copy one or more files and/or folders from one location to another location.

Generate File List

Example: C:\Users\me\Downloads\MyFolder> dir /b > filelist.txt
(The text in orange shows the command used once you've navigated into the directory from which you want to generate the list of file names.)
This tutorial contains several working answers for using Windows PowerShell to list files and folders.
Works with cmd.exe, but doesn't seem to work with Windows PowerShell.

Bulk Rename Files

Bottom line: use this tool: Bulk Rename Utility (Windows only.)

Rename List of Files With Batch File

It's easy to rename a group of files by running a batch file (file.bat), configured something like this: 

rename "Old-File_001.jpg" "New-File_001.jpg"
rename "Old-File_002.jpg" "New-File_002.jpg"
rename "Old-File_003.jpg" "New-File_003.jpg"

Using Windows or DOS, just create your batch file using the format shown above, and then double-click it to rename the files in the directory containing both your file.bat and files with the same names as those found in the "Old-File" (left) column of your file.bat file.

Regular Expressions

In theoretical computer science and formal language theory, a regular expression (abbreviated regex or regexp and sometimes called a rational expression) is a sequence of characters that forms a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations.

RegEx Tutorials

Any non-trivial regex looks daunting to anybody not familiar with them. But with just a bit of experience, you will soon be able to craft your own regular expressions like you have never done anything else.

Educate Yourself

Learn to Code

The Learn to Code movement has picked up momentum worldwide and that is actually a good thing as even basic programming skills can have a major impact. If you can teach yourself how to write code, you gain a competitive edge over your peers, you can think more algorithmically and thus can tackle problems more efficiently.
Lena Groeger: When I started learning to code, I was amazed by how much was out there: introductory videos, explanatory blog posts, tips and tricks and step-by-step guides. If you're a journalist who wants to make a news app or a student interested in learning to code, you have plenty of paths to choose from.

Multiple Codes

Learn to code while building a project. Free online courses include: HTML & CSS; jQuery; JavaScript; PHP; Python; Ruby; Web Projects; APIs

R

Learn R & Become a Data Analyst

D3.js

d3Vienno features a series of video tutorials, each about 10-12 minutes long, on using D3.js.
D3 Tools
A Chrome-specific bookmarklet that extracts SVG nodes and accompanying styles from an HTML document and downloads them as an SVG file—A file which you could open and edit in Adobe Illustrator, for instance. Because SVGs are resolution independent, it’s great for when you want to use web technologies to create documents that are meant to be printed (like, maybe on newsprint). It was created with d3.js in mind, but it should work fine no matter how you choose to generate your SVG.

Data Analysis Tools

D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.
Take control of your R code. RStudio is the premier integrated development environment for R. It is available in open source and commercial editions and runs on the desktop (Windows, Mac, and Linux) or over the web with RStudio Server. Download RStudio (for Windows, Mac, or Linux).
Open Refine is a standalone open source desktop application for data cleanup and transformation to other formats, the activity known as data wrangling. It is similar to spreadsheet applications (and can work with spreadsheet file formats), however, it behaves more like a database.
Wrangler allows interactive transformation of messy, real-world data into the data tables analysis tools expect. Export data for use in Excel, R, Tableau, Protovis, ...
HTSQL is designed for data analysts and other accidental programmers who have complex business inquiries to solve and need a productive tool to write and share database queries. HTSQL is free and open source software.
Jigsaw is a visual analytics system to help analysts and researchers better explore, analyze, and make sense of such document collections.

Dual Boot

Boot Disks

Rufus is an utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.

Network Issues

Post reviews various "fixes" found all over the web, and which "fix" actually worked for the post's author.
Path MTU Discovery (PMTUD) in Windows just doesn’t seem to figure out the MTU for a given path. So Windows uses the default. For the most part this doesn’t affect anyone. But failure of PMTUD will result in some websites not loading correctly, having trouble connecting to normally reliable online services and general Internet weirdness.
