Format strings are a handy way for programmers to whip up a string from several variables. They are designed to save the programmer time and allow their code to look much cleaner. Unbeknownst to some programmers, format strings can also be used by an attacker to compromise their entire program. In this guide, we are going to look at just how we can use a format string to exploit a running program.
In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.
We started with our system manager in the previous lesson in our series on building dynamic user interfaces, but to get there, aside from the actual transform, rotation, and scaling objects, we need to make objects out of code in multiple ways, establish delegates and events, and use the surface of an object to inform our toolset placement.

Are you looking for a little microbe magic? Think composting. Composting is a great way to reuse food and plant waste that you would otherwise throw into the trash, which would just end up in a landfill somewhere. During the composting cycle, microbes reduce this organic waste until it can be fed back into the soil as rich, crumbly compost. When returned to the soil, compost feeds plants and improves the nature of life underground. Sound like a great idea? It is — and it's easy.

I was on our new #nullbyte IRC channel when someone told me how tedious it is to install an OSX Virtual Machine on Virtual Box (I think it was wawa). We all know Linux rocks (gets acknowledgement from the crowd), but there are morons out there, multiplying at a never before seen rate, who use OSX. We at nullbyte should be prepared for anything and everything. So, in this guide I take you step by step to creating your OSX Yogemite VM.
Pickles come in all shapes, sizes, and names (gherkins in the UK, cornichons in France). There are even crazy flavors such as koolickles—dill pickles soaked in a mixture of Kool-Aid and brine, an American South favorite.

From the obvious (cooking) to the less so (home improvement), there are likely many coconut oil uses you're not yet aware of.
As you know, it's impossible to be a Steampunk without a pair of goggles. In fact, there are entire communities dedicated to judging other Steampunks based solely on their goggles. A Steampunk without goggles is like Samson without his hair, or a duck without a beak—totally powerless. As I'm sure you also know, the right pair of goggles can instantly render any outfit Steampunk, no matter what it looks like.
I chose to make this a Steampunk iPad case, but you can change the details and make it look as modern as you'd like.
