I got 80% for my security assignment!

This morning the lecturer was unhappy at everyone in the lab because nobody did his favourite question from the previous lab, even though we had one month to do it. Only me and another guy did it. The lecturer said he will put that lab question in the final exam.

Yesterday I submitted my SS assignment. Also got back the results of the FCS test during the lecture =/ didn’t do too well or too badly >.< above average but was lower than my expectations. Actually everyone’s expectations – the average score was 53/100 in the class, fourteen out of forty people failed. Guess the lecturer was a bit too strict on the marking, and the questions were almost all open-ended – completely NO multiple-choice questions.

I stayed up all night trying to understand and do today’s HF lab, and only went to sleep at 4:30am. Woke up ten minutes before the lecture and was almost late. Luckily I’m staying near uni… Anyway, the lab was really hard, only managed to get to halfway in the two hours. My lab mate and I decided to attend the make-up lab lesson at the end of the semester to complete the other half.

Today I got back my SETM assignment… didn’t do that well, but I passed!

In this assignment, I have to program a software that uses the Simple-DES (Data Encryption Standard) algorithm to encrypt and decrypt plain text file.

I just completed it. Have spent the past few days cramming to complete it, as I encountered several problems that were very difficult to fix.

More about the assignment, my report and program sources are available on the newly-created school page.

I have added a new page for my uni projects, so you can see what I’m doing (reports, programs, etc.)

It is accessible from the navigation bar on the left.

SETM assignment due tomorrow. Actually today already. Managed to complete the report on time (phew!). Lucky got an extension and last minute I got inspiration :)   Later can relax and go town for shopping and R&R.

The next two weeks are term break, however I still have the software security assignment deadline coming up, and I haven’t started =/

Oh yea, just found out today that although my prepaid card don’t have any credit left, I still can receive incoming calls/smses, and I can send out sms from the telco’s website. That means I can save money hahas…

For the Software Engineering Tools & Metrics assignment we need to profile and find bottlenecks of a free open source Java project and submit a report with the solutions and various kind of metrics. We have been given a Image Cafe software developed by our university, in a case that we couldn’t find a suitable project. ;-) Anyway most of us use the given program as our test program. We are using java -prof command and analyze data to find any bottlenecks and solve them.

NetBeans Profiler – This is special purposes it uses java -prof function and visualize data, so need to copy prof output to OpenOffice.org calc or any other spread sheet program and format them. To be used with NetBeans IDE.
