Wookey on Telepresence robot at Linaro Connect San Francisco 2017

Posted by Charbax – September 28, 2017

Wookey (who I also previously interviewed here: 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...

Autofocus test on Firmware 2.0 Panasonic GH5

Posted by Charbax – September 28, 2017

I am doing my first handheld autofocus test using the Panasonic GH5 and its new Firmware 2.0 update. I'm hoping that the auto-focus may be good enough for my style of handheld, always moving, constantly re-framing, focusing on faces and things people show off. What do you think about this Autofocus performance? This was filmed with Serge Broslavsky at Linaro Connect 2017, see his GH5 setup here. This video was filmed at 4K60p at 150mbit/s H264. Thus far the Panasonic GH5 firmware can't film 4K60 in HLG HDR mode and they don't yet offer an H265 option at 4K60 to save on bitrate at same quality for faster YouTube uploading.

Bero builds ARM Desktop PC Quad-core ARM Cortex-A72 Marvell MACCHIATObin

Posted by Charbax – September 28, 2017

Bero (Bernhard Rosenkränzer) from Linaro is building his own 64bit ARMv8 quad-core ARM Cortex-A72 Desktop PC with Nvidia GPU (possibly with a Radon GPU card support later), 16GB RAM, today is Wednesday, he hopes to have it running by Friday then I can film a new video. Bero and his colleagues have also worked on many other things such as AOSP TV, Trebble related unifying builds adapting a new partition layout enabling automatic updates among kernel builds to work properly.

OpenGPU on Altera Cyclone V FPGA at Linaro Connect 2017

Posted by Charbax – September 27, 2017

Fabrício Ribeiro Toloczko, ​Systems engineer of The Technological Integrated Systems Laboratory (LSI-tec) and CITI-USP (Interdisciplinary Center in Interactive Technologies from University of São Paulo) presents the OpenGPU, a real GPU implementation that proposes a methodology to progressively develop hardware from a software implementation, making the process for producing hardware more easy and fast. Today, it runs on an Altera Cyclone V SoC FPGA with a dual-core ARM Cortex-A9. This processor is used to keep running a Linux distribution, while sending and receiving data through the memory mapped communication with the FPGA. Mesa3D and Gallium's softpipe driver are used for creating most of the graphic pipeline. The FPGA holds one rasterizer, which is a fixed function in graphic pipeline. With that, it's possible to run any OpenGL application, doing the hardware and software changes in real time.

Serge Broslavsky’s GH5 setup with Zoom H5, monopod, light, some DIY, some from Aliexpress

Posted by Charbax – September 27, 2017

Serge Broslavsky is a software engineer at Linaro, he is filming a documentary about Upstreaming. Here he shows his Panasonic GH5 camera equipment which features the Panasonic 12-35 f/2.8 markII lens, Zoom H5 audio recorder, Zoom SSH-6 MS (stereo shotgun) capsule, Polsen OLM-20 Dual Omnidirectional Lavalier Microphone, DIY female TRS to dual male XLR cable. And from Aliexpress the Innorel H60 video head, Innorel RM80 video monopod with F-01 mini-tripod base for monopod, Long arca swiss style plate with dual flexible flash holders (both removed), QR-50 QR Plate Adapters (arca swiss style), 11" Magic Arm, 7" Magic Arm, Yongnuo YN300 video light, BB-6 fake NP-F battery (uses 6xAA), Boya BY-C10 shoe shockmount for audio recorder, Acoustic foam screen for shotgun microphone and more.

Christophe Arviset, ESA Gaia and Euclid Missions Online Data Sharing

Posted by Charbax – May 9, 2017

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.

Speeding up Android boot with Bernhard Rosenkränzer, Linaro Mobile Group

Posted by Charbax – April 11, 2017

Bernhard Rosenkränzer, also known as Bero, on the Linaro Mobile Group, talks about some of the latest things Linaro is doing on Mobile, since many of the optimizations that he has been showing over the past years have been integrated by Google into Android, here talking about some of the latest things Linaro is doing to speed up the boot time of Android devices, speeding up all aspects of Android and mobile.

Andrea Gallo, Linaro Segment Group Manager, intern at Acorn Computers

Posted by Charbax – April 11, 2017

Andrea Gallo talks about his role at Linaro and the ROI value for Linaro members.
