I recently moved to a bigger city, and of course the first thing that I setup was my internet connection.  I’ve had the same ISP for a couple of years now, and they’ve been alright.  I’ve noticed drops in service here and there but overall it was a tolerable experience.  However, as soon as I started watching my online shows in the new place, I noticed some dramatic changes in my viewing experience.  There were long periods of waiting for the shows to buffer, and I felt like I was relapsing to my younger days of dial-up.  I got so frustrated one night I even tweeted about it:

Just took me two hours to watch a 1 hour movie. Why I’m leaving @coxcomm. — Krono$ (@SuperKronos) January 28, 2013

I finally decided to switch over and give DSL a shot, but I didn’t cancel my Cable.  I figured I’d do a little testing and really see who was the better service after all.  I put together a pretty extensive document of my results.  You can find that document and all the data I captured and used in a link below. This blog post is a summary of what I found to be the important parts.

User George Duckett came across a weird thing while performing a simple ping:

He performed a simple ping request but missed a ‘dot’.  I assume he meant to ping 192.168.0.72 but instead ended up typing 192.168.072.  What’s really amazing though (as pictured below) was that it worked!!! but not to 192.168.0.72 it sent the ping request to 192.168.0.58 :

Browsing on the web may seem harmless to most, but we SuperUsers are typically a secretive bunch.  We’ don’t like data being shared about us unless we tell them to.

So when user Pickledegg asked about how much info can websites can get, it became a pretty popular question.

I am trying to determine if the information shown on the website www.whatsmyip.org is the absolute maximum amount of information that a webserver can obtain from a web visitor. Does anyone know of any other sites that will be able to get more information from the user passively like this? I’m not talking about port-sniffing or any kind of interaction from the user, just the info that a server can get from a ‘dumb’ visit.

So what’s the verdict?

Here’s what we found.  From What’s my IP they can determine the following (I removed un-important info, if I missed something feel free to comment):

• External IP
• Homename
• Proxy
• Internal (LAN) IP
• Operating System and version
• Screen Resolution
• Cookies Enabled
• Browser Plugins
• Location (kinda sorta)
• And a WHOIS Lookup

Basically is looked like this (I put green checkmarks across things that were correct):

But there’s more!  A browser can also give away your installed fonts! GASP.  Wait… what?  Why is that important?

User Informaficker had this to say:

Installed fonts are probably the most identifying piece of information as soon as you start adding one or two. Just because of the amount of fonts out there, it is unlikely to have the same set of fonts on two different computers. (As long as they are used by different persons)

This means that if you have any custom installed fonts on your computer, you have a greater likelihood to have a different “Font Identity” than others since there are lots of fonts out there.

How do I stop this monstrosity?

First DON’T LET IT!!!

Browsers are typically good at telling you what’s going on.  I suggest that you NEVER select Always run on this site (or other browser equivalents), and only allow trusted websites to run Java or Flash.  Disabling Java or Flash is another option, however with a majority of websites using either Java or Flash this can be difficult and annoying.

However, the browser can still access your External IP address.  A way around that is to use a Virtual Private Network (VPN).  I tested this out and it worked, including getting the wrong internal IP, since it picked up the VPN’s Internal IP and not my actual home networks IP.

Overall, it goes without saying to just be careful when ever your browsing the interwebs.

This weeks question of the week come from these two questions:

• Windows 8 Hyper-V – how to give VM internet access?

• How do I install and use Window Virtual PC in Windows 8?

One of them asked by Graham Clark, and the other is a self post by myself.  This prompted me to do a more formal review of Microsoft’s Hyper-V for Windows 8.

What is Hyper-V for Windows 8?

Hyper-V for Windows 8 is really called Client Hyper-V.  It’s similar in many aspects to the Microsoft Server’s Hyper-V (2008 and the upcoming 2012).  What’s different about Client Hyper-V is that it was customized to fit the portable environments, such as laptops, that developer’s find themselves in.  What does Hyper-V do?

In brief, Hyper-V lets you run more than one 32-bit or 64-bit x86 operating system at the same time on the same computer. Instead of working directly with the computer’s hardware, the operating systems run inside of a virtual machine (VM).

The number 42 is amazing, and so to honor Douglas Adams answer to live, the universe and everything, I have collected 42 amazing questions/answers that we haven’t featured yet.  These aren’t in any particular order, as they are all interesting or awesome in some way or another.

1 Storing hard drive near electric wire – Ever wonder if your hard drive could be ruined while being near electical lines well here’s the tl;dr answer:

In short, don’t worry about it, unless you’re working with some kind of industrial equipment with VERY high currents on that cable (the amount of interference emitted from a power cable is proportional to the current on it). Household currents are unlikely to be a problem.

2 What are PATH and other environment variables, and how can I set or use them? – Environment variable can be a powerful tool to use.  The answer is a great guide on the how’s what’s and why’s of environment variables within Windows.

3 Why do disks fragment? – With the advent of SSD’s and their completive prices there may come a day when fragmentation will become a thing of the past, but for now it’s something we need to deal with.  The answers still provide insight to the woe’s of the the past when it comes to disk drive fragmentations.

4 How does a CPU ‘know’ what commands and instructions actually mean? – There’s a lot of “magic” that goes on behind the scenes as you operate your computer.  All of this magic eventually ends up being assembly level instructions which in turn…  well that’s the question, and the answers are pretty good at explaining the basics.

5 What makes a laptop overheat? – Laptops are notorious for overheating, and this question/answer duo helps to try to explain what it is.

Windows 8 is out for MSDN account holders (including students with MSDN-AA access)!  And it’s set to release on October 26th.  With that there are bound to be tons of questions in regards to Windows 8.   This post is meant to be a collection awesome questions/answers found on Super User that are tagged Windows 8.  This is what we’ve got so far:

General Understanding/Installation

• What is the difference between Windows 8 Pro and Windows RT?

• How can I upgrade from Windows 7 to Windows 8 and keep my files and applications?

The New Modern Apps

• How do I exit a Modern UI app?

• How do I turn off Modern UI in Windows 8?

• How to delete contacts from the Windows 8 People app?

As time goes on, and more questions/answers come along, we’ll update this help all you Super Users out there with the new Windows 8.

Memory.  Every Super User knows that they need it, and if you’re like me, you can never get enough.  I know I somehow find ways to use up all 16 Gb of my memory on my desktop.  In fact, back in Nov 2010 Tom’s Hardware suggested that the minimum system RAM should be around 8Gb!

But what’s really frustrating is buying memory.  There are so many factors to consider that it can get overwhelming.  This is the same issue that Super User nathpilland had:

What am I looking for in RAM?

This is the one area of computer building that still has me in the dark, and I think a lot of people are with me… There are many different types of RAM, with each company having high and low end sticks. What is the difference between the high and low end? Also, what do the numbers in the latency mean? What is the speed rating (I know 1600 MHz is about normal) and how much is too much? What’s the difference between dual channel and single channel? Can you overclock/overvolt? Is there even a point to do so if this was possible? As you can see, I’m thoroughly confused here. I tried doing some research, but I can’t find this information anywhere on the internet. I’m not actually buying RAM, I’m just trying to get a better picture as to how all this works so I can be more educated on the hardware in computers.

So here we go.  This blog post is a stab at defining the basics you need to know about RAM.

A quick look over at NewEgg there were a few major categories that advertising threw at me:

• Type (DDR, DDR2, DDR3)
• Speed (typically in terms of 1066, 1333, 1600, etc)
• Timings
• CAS Latency

A lot of people have heard about Internet “cookies” and often they have a bad connotation  to them, but to web developers they are very useful.  So what exactly are they?  The official Wikipedia definition states:

A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is usually a small piece of data sent from a website and stored in a user’s web browser while a user is browsing a website. When the user browses the same website in the future, the data stored in the cookie can be retrieved by the website to notify the website of the user’s previous activity.  Cookies were designed to be a reliable mechanism for websites to remember the state of the website or activity the user had taken in the past. This can include clicking particular buttons, logging in, or a record of which pages were visited by the user even months or years ago.

This basically means that websites will save small pieces of data on your machine in plain text.  These have a wide range of uses, but here are some common examples that I can think of:

1. Netflix: Isn’t is awesome how it remember where you last left off?  This is done through cookies
2. Amazon (and other shopping sites): They remember what was in your basket last time you visited.
3. Stack Exchange: Remembers you, so you don’t have to log in every time.  (Actually this is a WAY more complicated process detailed here, but you get the picture)
