i am not able to instal graphic drivers for my lenovo 9227-AD1 through the mother board cd. Please help as i am not able to play any games.

write a java program for 4 digit encryption/decryption code generator using simple GUI in eclipse

This is pretty awesome, check it out!

My mp3 player is really crappy so it sometimes doesn't recognize books I rip, so if you want to play it in order you have to rename all the files. To make this easier, I merge each disc into one file. It's also great for other purposes. This program is free and works well!

Sometimes windows will shutdown for "updates", which is great and all except when you had an unsaved project in the works or a huge file conversion that you expected to be completed when you wake up, only to find your computer rebooted.

If you have a PS2/PS3 Eyetoy, but don't want to go and spend $30+ dollars on a new webcam, then this is for you.

When we think of a "structure" we often think of architecture, but data also often has structure. There are many different types of data structures: arrays, graphs, queues, stacks, and so on. We use these structures in order to be able to effectively store and access the data. Sometimes one data structure will be very effective, while in another situation not so much. Knowing and understanding the advantages and disadvantages of the most common data structures will help you more easily decide...

i wanted to format my computer through my friend. he said that he would be needing the cd which comes with the motherboard. as i have lost it i wanted to know where could i find its content online for free and how.

Today, we are going to combine what we learned from the Introduction to Cryptography article with our Java programming skills. If you are new to Java, check out Matthew's Learn Java: Part One for a quick beginner's lesson, or check out some of the Java tutorials directly on Oracle.

my friend has bought a game called cashflow. i borrowed the cd from him and installed it on my pc, but it could not be played when the cd was not inserted. please help me to hack the cd

Hello, I would like to make a guide for checking HDD health on your computer but I'm not entirely sure if it's suitable for this World. Would you like me to make one?

Today isn't actually Pi Day, but I was unable to get this article out in time. Pi Day was actually yesterday, March 14th (3.14), so let's call this a post-Pi Day treat!

Industrial espionage, social engineering and no-tech hacking are all very real, and there are simple precautions that you can take to protect yourself, which this article will discuss. Whether you are a high-profile businessman or a housewife (or househusband), keeping the information you want to remain private private should be important to you.

Have you ever forgotten your password and didn't know how to get back on your computer? Or ever had an annoying roommate you wanted to play a trick on to teach them a lesson? Or perhaps overly religious parents who think the internet is of the devil and won't let you read online articles about elliptic curve cryptography applications to C++? Well, then this article is for you!

Last time, we looked at archaic cryptography, so you should have a basic understanding of some of the concepts and terminology you'll need. Now, we'll discuss one of the most important advances in computer security in the 20th century—public key cryptography.

Cryptography is a quintessential part of computer security in the modern world. Whenever you buy something on eBay or log into Facebook, that data is encrypted before it's sent to the server in order to prevent third parties from eavesdropping and stealing your sensitive information.

There is a vast amount of knowledge out there on computers! In fact, it is so vast that no single person could ever possibly ever learn everything there is to learn about hacking or computers in general. People usually specialize in a certain field: cryptography, computer security, networking, software development, testing, and so on...It's probably a bit premature to decide what you want your speciality to be, but keeping the question in the back of your mind will help give you direction in...

I recently found this video series that discusses (in a more round about way) the theories that make cryptography what it is today, which goes great with my most recent blog post. I haven't finished watching them all yet, but so far they have been fairly good and I would recommend watching one to see if you like it?!

I have decided to write a series on classical cryptography and if that goes well, then I will do some posts on modern cryptography.

Useful little tutorial!

Anyone have something specific they would like to learn about? I have had a lot of ideas floating around in my brain lately, but whenever I think of something good, it seems like Null Byte has already done it!? :)

An old blog that I hope to reincarnate in the near future...What do you think so far? (excuse the self promotion)
