Wookey (who I also previously interviewed here: https://www.youtube.com/watch?v=5XdgQ7AmWX0) has been bootstrapping ILP32 in Debian, the 32-bit ABI that will run on aarch64 core with no 32-bit instruction set support. He has been doing this using Helmut Grohne’s excellent ‘rebootstrap’, which uses the work Debian has done over the last few years to make it self-bootstrapping (multiarch, dependency-loop removal, build profiles, cross-building support, ‘botch’ dependency analysis tools) to automate the process of a bootstrap. This lets people doing bootstraps of new architectures concentrate on just the stuff that has actually changed due to the new arch, and allows repeatable builds.

He is attending Linaro connect in San Francisco this year using a Beam telepresence robot, in order to avoid the hefty couple of tonnes of emissions that flying across the Atlantic generates. That’s slightly more than one’s person’s annual sustainable allowance for _everything_: food, transport, heating, stuff, and he reckons eating is more important than geek conferences given that we really do have to choose…

Christophe Arviset is the Head of the Data and Engineering Division at ESA’s European Space Astronomy Centre (ESAC). The European Space Agency’s (ESA) current mission Gaia and upcoming one Euclid will generate massive amounts of astronomical data to be made freely available on-line through powerful data management systems. This big data era brings a change of paradigm and associated big challenges for building these missions’ archives. The current use case of “bring the data to the user” is being replaced by the new concept of “bring the user to the data”. This new generation of science archives is transforming into science exploitation and collaborative platforms, where the users can send her/his code to the data, run it on computing and storage services provided directly by the archive (where the data reside), and easily share all this with other scientists they’re collaborating with.

You can watch Christophe Arviset’s keynote at Linaro Connect here:

Andrea Gallo talks about his role at Linaro and the ROI value for Linaro members. He also covers his early days as software programmer and summer student at Acorn working on the very first ARM-based Archimedes, when he met ARM guru Sophie Wilson who I interviewed here 1of3, 2of3, 3of3 Andrea talks as well about the challenges that made Acorn turn into what ARM is today.

Robert Wolff and Jon “maddog” Hall talk about the opening keynote from Linaro Connect in Budapest #BUD17. Check out maddog’s reaction to the on stage IoT demo, which used not only Cabon and Nitrogen IoT boards, but also the new Sensor Hub board. Robert and maddog also touched on the various 96Boards announcements around newly available Consumer, IoT and Enterprise edition boards such as the Orange Pi, Oxalis and the MediaTek X20 Professional development board and how it all fits in the 96Boards ecosystem.

David Rusling talks about the latest things that are happening and going to happen at Linaro at Linaro Connect Budapest 2017. You can watch my interview with him from nearly 5 years ago here.

Joakim Bech talks about Linaro’s work in OP-TEE (Open Portable Trusted Execution Environment) small OS-like environment that sits aside a rich operating system, for instance Android. The purpose of the TEE is to keep all secret credentials and data manipulation in the small TEE rather than in a larger rich OS that is often the vulnerable target of malware and hackers in general. In order to reach this goal, application software is architected in a way such that sensitive functions are precisely defined and offloaded to the TEE in the form of Trusted Applications.
