Since it started in 1970, the CERN School of Computing has visited 18 countries and it is 22 years since the school was last held in the UK, in Oxford. We are therefore happy to return there, this time to Uxbridge, 40 km west of London. The school is hosted by Brunel University, a local organizer, and will take place from 23 August to 3 September.

The school is aimed at postgraduate students and research workers with a few years' experience in scientific physics, computing or related fields. The programme is organized along three main themes.
• Data technologies – presenting state-of-the-art technologies and options for data storing and management in particularly demanding environments, through lectures and practical sessions.
• Base technologies – addressing the most relevant underlying technologies for software development security, networking, hardware architecture and virtualization. Lecturers come from the US and CERN to teach theory and organize practical work.
• Physics computing – focusing on informatics topics specific to the HEP community. After setting-the-scene lectures, it addresses ROOT and data-analysis technologies. It also offers a range of practical exercises on these topics.

Examples of questions that will be answered at the school include:
• How to bridge Grids and Clouds using virtualization technology?
• Is it possible to simplify LHC physics analysis using virtual machine?
• How can reliable storage services be built from unreliable hardware?
• Why are tapes still used in high-energy physics data storage?
• How can I write code for tomorrow's hardware, today?
• Do you want to see your software with attacker's eyes?
• Can you hack your own code?
• Do you know what "code injection" and "integer overflow" have in common?
• What are the key statistical methods used in physics data analysis?

As always, since 2002, the prestigious CERN School of Computing Diploma will be delivered to the participants who succeed in the final optional examination, complemented by the Brunel University Certificate of Credits.

To respect a successful tradition established during the last decade, in addition to the 50 hours of tuition, a sports programme will propose two to three hours of sport every afternoon for those interested, featuring a rich palette of physical activities.

Further information can be found on the CERN School of Computing website (www.cern.ch/CSC) where you can find details about the programme, practical information about this year's school and details of how to apply, including the application form. The deadline for all applications is 3 May.
