I’ve been enjoying the break finishing up all the current unix assignments before the break began. I guess the last thing I did that I haven’t mentioned yet is the future of unix paper.  I thought this was an interesting paper to write about and research as technology in the future has always been an interest of mine. Upon finishing the paper I didn’t realize that part of the submission was creating a makefile to convert the paper to html and pdf. Since I started this paper in Word I wasn’t sure where to go and how to get it in to markdown format. Turns out markdown format is pretty much just plain text, so I was able to take the plain text file and simply add some white space where paragraphs were needed which wasn’t nearly as bad as I thought it would be. After getting the markdown file, converting it using pandoc was as simple as just googling what the command to do so was. Setting up the makefile after this was a piece of cake.

In 3574, we are getting a bunch of homeworks as he is trying to squeeze everything into these last couple of weeks which is really annoying. So we got stuck with an assignment over break. This proved to be pretty tough especially without being able to go see the TA for help.  The homework was on POSIX message queues.  I managed to set up everything necessary for the homework, but was stuck on one of the most trivial parts. The parameter for the message in the send and receive functions is a char*. I didn’t realize how annoying this was to convert my messages between char*s and QStrings.  Turns out everything I was doing wrong had to do with my error in conversion. I was using the same char* as my send and receive message because I didn’t realize how it was really storing the information into the pointer.  By having 2 char*s, one for receiving, and one for sending, this cleared up the issue. Such a small thing for all the debugging I had to do. Debugging for this homework was extremely annoying since you had to run 4 separate processes of the same program, then a fifth process of a different program. All 5 processes had to be run in a certain order, and remade, and reran every time I made a small change. It would take about 30 seconds just to get to the point where I could rerun the program. I finally got it working though after a few emails with the TA,
