A community Q&A for HEP Software and Computing ?

• Andrea Valassi (CERN)

Room: 31/3-004 - IT Amphitheatre How often do you use StackOverflow or ServerFault to find information in your daily work? Would you be interested in a community Q&A site for HEP Software and Computing, for instance a dedicated StackExchange site? I looked into this question...

Enabling Open Hardware through FOSS tools

• Tomasz Wlostowski (CERN)

Room: 31/3-004 - IT Amphitheatre Software developers often take open file formats and tools for granted. When you publish code on github, you do not ask yourself if somebody will be able to open it and modify it. We need the same freedom in the open hardware world, to make it truly accessible for everyone.

Reimplementing the LBD DNS Load Balancer with concurrency in GO

• Ignacio Reguero (CERN)

Room: 31/3-004 - IT Amphitheatre Using the current configuration with 430 aliases, today’s implementation of the LBD DNS Load Balancer does one cycle through all aliases in around 240 seconds. We have a scalability limit of 300 seconds - that is the update period of most aliases. This talk will present a PoC showing how the time could be reduced to just 12 seconds.

Coding Pi Science days at CERN

• Brice Copy (CERN)

Room: 31/3-004 - IT Amphitheatre The CODING PI SCIENCE days are an opportunity for STEM Teachers and students aged 12 to 18 to get familiar with programming using fun scientific projects.

Block storage subsystem performance analysis

• Julien Leduc (CERN)

Room: 31/3-004 - IT Amphitheatre You feel that your service is slow because of the storage subsystem? But there are too many abstraction layers between your software and the raw block device for you to debug all this pile... Let's dive on the platters and check out how the block storage sees your I/Os! We can even figure out what those patterns are meaning.

Privacy - why and how we should fight for it

• prefers to remain incognito

Room: 31/3-004 - IT Amphitheatre **THIS TALK WILL NOT BE WEBCAST/RECORDED** "I don't have to care about this privacy hype, I have nothing to hide." "Yes, they know a lot about me, but there is nothing I can do about it." "Today you simply have to give up your privacy for your security." Well, I don't think so and here is why...
