Quality Meetup no. 15 - Fixing a billion dollar mistake

Feb 9, 2018
java, conferences

On the 8th of February 2018, during Quality Meetup #15, I gave a presentation titled “Fixing a billion dollar mistake”. Tony Hoare introduced Null Reference w in ALGOL language in 1965. He calls this decision a “billion dollar mistake”. It was so easy to implement and probably it caused a loss of millions of dollars due to the mistakes done in the software over the 40 years. During the time, people came up with different ideas of solving that problem with software libraries, good programming practices, static code analysis and compile time code analysis. ...

Introduction # In the past months, I’ve attended a few conferences and meetups related to IT. I also plan to attend a few more in the last quarter of the year as a speaker. I’d like to show you a few tips, which can encourage you to attend such events, be more involved in them and spend some time away from your desk ;-). If you are working in a software company, in the most cases you could treat going for a conference as a non-customer facing business trip, so your regular days off will be safe and can be used for your personal plans and holidays :-). ...

Get past the syntax - the real scare is in the semantics

Jul 6, 2015
java, conferences

Dr. Venkat Subramaniam presented an interesting point of view during his talk at Devoxx conference. Programmers, who start learning a new language, often complain about syntax. They focus on using available keywords and constructions instead of trying to understand their meaning and purpose. Programmers also have their own habits. That’s why Java has similar syntax to C and C++. Creators of Java designed new language with syntax, which was familiar to them, with significant improvements. ...
