Conference greetings from China

IEEE sponsored ICT 2014 conference was organized the in Xi’an China 11-13.09.2014. Xi’an is a historical city, has been the capital of China before Beijing. The city is lively, modern and is increasingly attracting tourists. The most well-known thing is the terracotta army nearby, but the walls of the old city are also impressive. Unfortunately, only few of the old-looking buildings are not really old. Due to tight schedule and rainy weather the tourism part of my trip was extremely limited.

Gate in the famous walls around the historical center of Xi’an.

The conference had several parallel tracks. Unfortunately, not many participants attended the sessions and about 1 out of 4 presenters did not show up. Anyways, the review process for the conference was ok (I co-chaired evaluation process of one track 🙂 ) with acceptance rate of about 25%. Note to point-counters: our dear JUFO system seems to give rank 1 to this conference.

The conference was held in a nice conference center with a patio that made a contrast to neighbouring buildings:
I just wonder how the water got its color. Anyways, some birds and fishes live in it.

I was not there just because of my role in program committee, but I also presented paper “Tool Support for Planning Global Software Development Projects” by Hasrha, Outi and I. This was about using genetic algorithm to help planning of GSD projects. The size of my audience was over average, which is still not too much. The questions ranged from “is Darwin available for download” to “why genetic algorithm instead of hill climbing, simulated annealing etc.

Notes on talks that I found interesting
Keynote by prof Hideko S. Kunii, Shibaura Institute of Technology
This influence lady gave a really interesting keynote about the problems in software business in Japan. Examples of the problems are

  • Management in companies has HW career, competence and mind-set. As we know, this leads to problems in companies that try to live in SW-driven industry, but it could cause problems to countries, too.
  • Young and talent students do not want to aim at software engineering or computer science. The profession is seen as low-pay, long-day, dull with humongous culture.
  • Japanese people – including students – are bad in English.
  • The typical ICT service and application delivery organizations have deep sub-contracting hierarchies. This prevents companies from starting business innovation.
  • Cultural issues: rigid organization and admin, low number of start-ups, slow adaption of rapid changes.
  • Agile adoption is low (only 15% when US had 85%). Interesting note while the promoters of Lean approaches use those Japanese words and talk about Toyota way.
  • Universities have not been allowed to expand SW teaching and research, university research is too far from industrial problems, only old and senior people are allowed to teach.

But, there are also several initiatives to correct the above problems.


Structural Analysis of Source Code Collected from Programming Contests
(Bokuk Park, Haesung Tak and Hwan-Gue Cho; Pusan National University, Busan, South Korea)

  • They have datamined correspondence betwen code quality in terms of passed test cases and complexity-related code metrics. The source was from coding contests of students from various levels of schools (from elementary schools to university degree).
  • TUT-note: some of these ideas could be used for our CoRED code-camp data. Maybe could also use the front-end of these guys in some industry cases in N4S.


Illustrating Software Modifiability – Capturing Cohesion and Coupling in a Force-Optimized Graph
(Johannes Holvitie, Ville Leppänen; University of Turku)

  • The main purpose is to see potential propagation of SW changes to one element/module.
  • TUT-note: could be used to find components for remote work in GSD research.(in maintenance phase)


HOTDOL: HTML Obfuscation with Text Distribution to Overlapping Layers
(Sungjae Han, Minsoo Ryu, Jaehyuk Cha and Byung-Uk Choi; Hanyang University, Seoul, South Korea)

  • This paper gets my hacker/nerd award! The paper presented a method to prevent illegal copying of the HTML-content from the browser. The idea was simply to convert text areas to series of overlapping and transparent panels – each panel shows random subset if the characters.
  • Some details were hidden since they have patent pending and are negotiating with some internet company.
