I have a series of posts that I want to blog about over the next few weeks. The topics of these posts are things that will help you become better at solving puzzle problems. They are not the solutions themselves but rather some of the tools that you should have in your toolbelt to help […]
So I recently I had to take a hex address stored in a string and convert it back to a pointer in C++. So it basically had to go from this string address = “0X…abab123a” To this char *address = ? I’ve never had to do that before so I wasn’t really sure if it […]
The Vigenere Cypher is actually a very simple and efficient Cypher. I use the term efficient in terms of being hard to crack by a human. In terms of being cracked it’s probably pretty easy so… please don’t use this cypher for anything other than academic purposes. One thing about the Vigenere Cypher is that […]
We have all been there… faced with a task that is so overwhelming we don’t know where to begin. The best place to begin is now. But wait… “now” is a point in time not in the sequence. Yes. That is correct but the best way to tackle something when you don’t know where to begin […]
I’m writing this post in hopes that it will help many programmers out there that will run into this issue. Recently, I helped write a small program that read in data from files. The input composed of several different files and different formats for the files. The data was then used to build a list […]
In my previous post, I said that Coding Schools are not the best value for your money. Why is that? Is it because the program information is not valuable? Is it because the completion certificate is worthless? Is it the drop out rate. None of those issues is the problem. The content is valuable. The […]
I’ve been tutoring here and there for the last two years. Most of the time I tutor approximately 5 hours or so a week. This opportunity has provided with many rewards. Among them the opportunity to tinker with the fun stuff. College Instructors provide students with a lot of fun stuff. It may not be […]
If you are in college, chances are you will need to write some programs to some problems your professor made up all by himself. For example, he or she may ask you to find all the unique words in Moby-Dick. Then she will ask you to count how many times they occur. And then later […]
It’s been a long time since I was first introduced to binary trees. Back in college, I don’t remember if we actually tackled the problem, if I tackled it or if I just took a sample solution from google. Never the less, recently I was intrigued to find out exactly how deleting a node from […]
One recent incident led me to think of another that led me back to some profound words by a previous supervisor “If it was easy, we wouldn’t need you Fernando”. I think those words came after he thought I was complaining about how hard the current problem was. I spent more than a few good […]
