There was a project to control real robot - the previous group managed to move it and even speed it up, until it hit the wall. The goal for next project was to slow it down or even stop it to avoid the crash. Nice, but a bit too hardware oriented and [[I]] was more a software guy. Then there was a project to build a database system for a hospital - nice and valuable goal to help poor patients, but [[I]] was not huge fan of [[SQL]] & co. And so on, so on.

	However [[I]] wasn't alone. Several other guys were disappointed with the presented choices. We started to chat and agreed what we would like to do: we'd like to build an [[IDE]] - something like [[Delphi]], but to run on [[Linux]] - e.g. for [[XWindow]] system. Luckily there was a visiting professor from U.S. - [[AdamDingle]] - we contacted him and (as he didn't know what it is like to lead seven students during software project) he agreed to do it. We officially announced the project and started weekly meetings. A usual meeting lasted an hour and we chatted about the great design, plans and then went into a pub. It was a hard work, but we managed to do it for almost a year. Without producing a single line of code!		However [[I]] wasn't alone. Several other guys were disappointed with the presented choices.

	We passed the exam with excellent marks. Some people say that it was because at that time nobody from the reviewers could execute [[Java]] program. So they couldn't try [[Xelfi]] themselves, but had to trust our demo and we obviously knew what features to avoid from it. The only material they could study alone was documentation, and we had an enormous amount of that thanks to another [[Java]]'s invention: [[Javadoc]]! We impressed everyone by generating hundreds of pages describing (well rather just listing) all the methods we had in the system. No surprise everybody was impressed.
