3 easy steps to setting up a zero configuration multi-platform web server with NodeJS and local-web-server

In this technical post I am going to illustrate how you can use the simple local-web-server package for NodeJS to start your web server in a few commands.

Let’s get started!

Step 1 – Installation

First, install NodeJS from http://nodejs.org/download/

If you are using Windows, then make sure you download the MSI package because it is so easy to install.

Keep the default options as you’re installing:

After installing NodeJS, open an elevated command prompt (i.e: run cmd.exe as Administrator) and type the following command in order to install the local-web-server package:

npm install -g local-web-server

You should see something like this:

No errors imply that the package has been successfully installed! Continue reading

How to turn your bookshelf into an e-book library: Digitizing all of your books

digitizing-books-scannedSince I moved to the US, I collected around 350 books. I love books and the thought of giving them up is not a pleasant thought.

Each time I used to move from an apartment to another, the majority of boxes would be packed with books. Each time I travel somewhere for a long period, I miss being able to grab a book from my bookshelf and start reading (most of my books are old and they do no exist in digital format anyway). It is clear that I have attachment to those books.

To break this attachment, I had to make a couple of decisions. The first was whether to just forget about the books, leave them on the shelves and get myself busy with another chore. The other decision was whether to scan and /or give away the books. With that came other questions like how to scan books and convert them to eBooks, what methods to use, how much efforts would it take to convert the books, etc.

I decided to get rid of the books and the trim down on the space they occupy. For the reasons outlined later in this blog post, I chose to destructively scan my books. By scanning the books, I get a digital and searchable copy of my books (in PDF format).

In this blog post, I will share with you different ways you can use to digitize books and then the remainder of this blog post will illustrate how I destructively digitized all of my books and what tools I used. Continue reading

Batchography: Changing the MAC address on Windows – A free Batch script

batchography-good-resIn a previous post entitled “How to get unlimited free Internet at Airports“, I showed you how to circumvent the time limit imposed by the “free” Wi-Fi connections in certain airports.

For that trick to work, you were required to update the MAC address of your computer each time the free time is over.

In this blog post, I am going to share with you the ChangeMACAddressBatch script that I wrote with the help and instructions from the excellent Batchography book.

The script makes use of various recipes illustrated in the Batchography book (in Chapter 4) and uses the various Batch scripting language syntax (Chapters 1 and 2) and methodologies (Chapter 3). Therefore, I will not be explaining the script’s contents or how it works because it will become evident if you read the Batchography book.

How to use the script interactively

To begin with, you need to run the script with administrative privileges.

Running the script as an administrator


On Windows 8 and above, just press Win+X and choose “Command Prompt (Admin)” like this:

chg-mac-run-elevated-command-prompt

Otherwise, if you are using the Windows Explorer window, then right-click on your script and choose “Run as Administrator”:

chg-mac-run-as-admin

Starting the script

When you first run the script, you will be presented with the main menu that will show you a list of all the adapters you have on your system.

On my laptop for instance, I have 4 adapters:

  • An Ethernet adapter
  • 2 x VMWare virtual adapters
  • A Wi-Fi adapter

Using the keyboard, type the adapter number that you want to inspect and/or change its MAC address:

chg-mac-main-menu

Let’s press “4” in this case and go inside that adapter’s information screen. Continue reading
