The Power of Steganography

The past week (while I was ill), I was really bored at home watching YouTube videos and crying so much about how painful my stomach felt. I was looking through a set of videos from Tinkernut (or Gigafide), a very informative YouTube channel that teaches quite interesting things. One of the videos I watched was about steganography (the art of concealing a message, image or file within another message, image or file). I found it quite interesting, because it can be quite useful to use.

The easiest one in the video is LSB (least significant bit) steganography. It uses an MP3 file and an image. He then takes the MP3 file and “puts it” into the image. Here are the steps:

Open command prompt (Window R -> cmd )

You will need the directory address of your files. It is recommended that you keep them in one folder for organizational purposes.

In the command prompt, go to the folder where you have all your files using the cd command. Remember, use the folder’s directory address (the folder must exist for the command to work):

cd "desktop/Folder/Special Folder/Why are you in here/Seriously Get Out/This will take some time/Just leave now/Please leave this folder/Do not touch this folder/You thought this was the last folder/You thought wrong/Please get out/Seriously get out/GET OUT/PLEASE/IM BEGGING HERE/VIRUS/SUPER VIRUS/MEGA VIRUS/porn/You perv/Fine I quit/two more folders/next one is the real folder/steganography folder"

You should be in the folder directory of your folder. Enter the following:

copy /b name-of-the-image.jpg + the-song-you-want-hide.mp3 name-of-the-new-file.jpg

Hit Enter and you should have a new file in your folder. Tell your buddy that (s)he needs to change the file extension from JPEG (.jpg) to MP3 (.mp3) get the actual song you wanted to send.

It’s quite useful. Although the “easiest” way is just put it in an encrypted zip file, but that’s no fun.

Math Jokes

In celebration of Math, here are a few math jokes that’ll surely make you giggle. If, for some unexplainable reason, you don’t get it, Numberphile has a great video explaining them.

1. A man walks into a bar and asks for an order 10 times more drinks than everyone else. The bar man says, “now that’s an order of magnitude.
2. An infinite number of mathematicians walk into a bar. The first mathematician orders one pint, the second ordered one-half a pint. The third ordered one-fourth of a pint. The fourth ordered one-eighth of a pint. Eventually, the bar man gives two pints and says, “you mathematicians, you just don’t know your limits.”
3. Why is six afraid of seven? Because seven eight nine.
4. How do you make seven even? Remove the s.
5. Two cats are standing on a roof. Which one falls off first? The one with the smallest mu.
6. What did zero say to eight? “Nice belt.”
7. What do you get if you cross a mosquito and mountain climber? Nothing, because you can’t cross a vector and a scalar.

I’ll be honest, before I even watched the explained portion (I basically skipped each explanation and went through the jokes first before actually watching the video in full), I didn’t quite get most of them (especially numbers 2 and 7). After the video, I laughed and continued on with my day.

Here’s the video from Numberphile:

Beautiful and Fast

As much as I despise the user interface of Windows 8, I can’t talk crap about its speed. It’s fast and I won’t be arguing with the fact.

A friend sent me a video which I found very interesting. I see it as “comedic genius” coming from Microsoft and I find it to be a very effective way of marketing the product.

Is it just me, or is the girl’s face and the way she looked at the camera kind of scary? It freaked me out for a bit…

How I Love Nostalgia

I’ve been a computer geek for a quite a while now. Of course, I wasn’t able to understand the beauty behind it all, like the coding and software and everything in between. One thing’s for sure, I’ve been a computer enthusiast for a long time. Anyways, here’s something to get your nostalgia running!

Here’s a little preview for the Chewy of the Week…

Laughing is Good

Here are some great computer jokes that will surely make you laugh!

The General Ones

Like car accidents, most hardware failures are due to driver errors.

Evolution is God’s way of issuing updates.

My software doesn’t have bugs. It just develops random features.

These must really hurt for Windows…

The box said “requires Windows Vista or better,” so I installed Linux.

What’s the difference between a computer virus and Windows? Viruses do something.

Computers are like air conditioners; they stop working after you open windows.

Apple still sucks…

The best accelerator for a Mac is the one that causes it to speed up at 9.81 m/s^2.

While Linux literally gives away stuff for free, Apple resells it for $99.

A Mac user calls tech support and asks, “what is Linux?” The technician begins laughing and answers, “it’s an open source operating system, meaning any programmer can alter and change the source code. It’s also stable, so stable that NASA uses it at the Space Station. Oh, and it’s free!” The Mac user immediately hangs up.

The Ultimate Star Wars Prank

This has just entered my bucket list. After watching this, I can’t just simply let the “gullible people in an elevator” opportunity go to waste. I have to do this before I die.

The force is strong with this one.

This Made My Day!

Hello everyone! I hope everyone had a great weekend. It was an awesome May the Fourth and Cinco de Mayo weekend. Take hold! I call it Pardon the Pun (PTP). I found inspiration reading puns online when I was bored.

Here you go:

Why did the programmer quit his job?

Because he didn’t get arrays!
