Do We Really Need Wi-Fi in Schools?
Why do I think Wi-Fi is needed in schools? Times have changed. We need to adapt to the changes. I believe the internet is probably the most important tool available today.

It allows an even playing field for people who don’t have the information and knowledge to be able to get it. Students today are the future. They need to be able to access as much knowledge as possible to be...

Traditional recursion vs Tail recursion
Recursion is a frequently adopted pattern for solving some sort of algorithm problems which need to divide and conquer a big issue and solve the smaller but the same issue first. For example, calculating fibonacci accumulating sum and calculating factorials. In these kinds of issues, recursion is more straightforward than their loop counterpart. Furthermore, recursion may need less code and looks more concise. For example, let's calculate sum of a set of numbers starting with 0 and st...

One problem we were having is that some of our batch processing jobs were taking too long to run. In order to speed the processing, we tried to split the processing file into half, and let a separate PHP process run each job. Given that we were using a dual core serv...

That part of what is available from search engines such as Bing or Google ...
The Wasteful Legacy of Programming as Language
A few years ago I visited a friend who is a graduate student in linguistics. After some time he asked me if I was aware of the work by Chomsky on formal languages. I told him that yes, Chomsky work was a basis for much of the developments in theoretical computer science. More than that, I was glad to learn that there was something technical that I could share and discuss with other people in linguistics. At the time I found this was just a great coincidence. It was only recently, though, t...

How to organize a successful technical party?
Since last year, I began to take part in some technical parties. Some are held very successful, while some seem not.
