Esko Ukkonen’s birthday coffee

The head of the department, Esko Ukkonen, celebrated his 60th birthday. The celebration was held in Exactum at the end of January. The party was attended by employees of the Department of Computer Science and invited guests. The programme included both congratulatory speeches and songs, with a quartet from Wiipurilaisen Osakunnan Laulajat (the Viipuri students’ association singers) singing a song for a former active member. Esko was inspector in Kymenlaakson Osakunta (the Kymenlaakso students’ association) for over ten years.

Esko Ukkonen’s career at the Department of Computer Science began in 1972. The first year, he worked as a part-time teacher, and the following year he was already part of the research community. He took his Master’s degree in mathematics in ‘73. The same year he transferred to computer science and became a PhD student for Martti Tienari, the founder of the Department of Computer Science. After defending his thesis it took only a couple of years before he was conferred his first assistant professorship in 1981.

During his long academic career, Esko has also worked internationally: at Berkeley in the United States and at Freidburg in Germany. Professor Ukkonen was elected head of the department for the next four-year period starting in 2010.

At his own request, the money collected for his present was given to the Red Cross. Esko wants to thank you all for contributing to a good cause!

A really welcome present was the volume in honour of him made by his former students. The volume consists of some twenty research articles written by Professor Ukkonen’s former students and collaboration partners.

Once more, congratulations to Esko!

Cold Aisle Containment in our server room

On Thursday 10 March 2011, we installed a so-called Cold Aisle Containment in the server room shared by the Department of Computer Science and HIIT. This is a rustic contraption made from transparent PE plastic, air-conditioning tubes, and a great deal of duct tape. It cuts back on the need to cool the server room very efficiently, as the air-tight plastic stops the intake and exhaust air from the servers from mixing.

HIIT study: Servers run well around zero degrees

Lots of energy can be saved by using outside air directly for cooling in data centers in the north. In a study by researchers of Helsinki Institute for Information Technology HIIT and the University of Helsinki, computers functioned correctly over extended periods of time when run in harsh winter temperatures. Commercial, off-the-shelf computers ran well even when the outside temperature was -22C (-8F).

Master's degree studies in computer science popular among international applicants

Master's degree programmes in computer science at the University of Helsinki were very popular among international applicants in spring 2010. This academic year the department of computer science at the University of Helsinki decided to offer two of its Master's degree sub-programmes, namely the programme on Algorithms and Machine Learning and the programme on Networking and Services, completely in English from the beginning of Autumn term 2010.
