Chris Mattmann is a frequent speaker at ApacheCon North America and has a wealth of experience in software design, and the construction of large-scale data-intensive systems. His work has infected a broad set of communities, ranging from helping NASA unlock data from its next generation of earth science system satellites, to assisting graduate students at the University of Southern California (his alma mater) in the study of software architecture, all the way to helping industry and open source as a member of the Apache Software Foundation (ASF). When he's not busy being busy, he's spending time with his lovely wife and son, braving the mean streets of Southern California.

Conference season is here. And, with it comes a barrage of swag just waiting to find its way to bottom of our bags or a pile on the top of our desks. But we love our swag, don't we? We redistribute it later to friends and collegues we think could really use another sticker for their laptop or another T-shirt for their T-shirt drawer. Maybe another water bottle for all those hot summer days ahead or an umbrella shant we get caught in the rain! Oh, and the beloved collector's item, the lanyard. How they grow and heave wherever they might collect year over year of our attendance to conferences far and wide.

Google has open-sourced Santa Claus. Or at least the code for its online Santa Tracker. For those of you who are more “bah humbug” than “pass the eggnog”, Santa Tracker offers an online method of tracking Santa's fictional progress through the logistical chore of stuffing soon-to-be-ignored amusing plastic tat down the chimneys of the world's best-fed and most-privileged children.

In February 2015 the Plasma developers met in the Blue Systems office in Barcelona to discuss and plan out where we would take Plasma over the duration of the next year. The sprint consisted of active Plasma developers and visual designers from around the world, from Canada to India. The meeting consisted of equal parts hacking and group discussions about plans both in the near and far future in breakout sessions throughout the week.

Allwinner unveiled a Cortex-A7 based SoC for smart connected cameras that integrates its HawkView image signal processor, and supports Linux and “Camdroid.” Allwinner jumped on the ARM Cortex-A7 spec early, using it for its popular, low-priced system-on-chips like the Allwinner A10, dual-core A20, and quad-core A31. Like the A10, Allwinner’s new “V3? SoC has a single Cortex-A7 core, in this case clocked to 1.2GHz. However, Like a number of TI’s Linux-focused, DSP-based DaVinci SoCs, the V3 is designed for camera applications. It follows Allwinner V-Series SoCs including the quad-core, Cortex-A7 V10 and Cortex-A8-based V15.

Embedian has launched a SMARC COM that runs Linux on a Freescale i.MX6, and offers up to 2GB RAM, 4GB eMMC, -40 to 85°C operation, and a Mini-ITX baseboard. Embedian’s SMARC (Smart Mobility ARChitecture) form-factor SMARC-FiMX6 computer-on-module follows Embedian’s earlier SMARC-T335X, which integrates a TI AM335x Sitara system-on-chip. The SMARC-T335X module also formed the basis for a pair of Embedian sandwich-style Smart SBCs. The similarly SODIMM-style SMARC-FiMX6 instead showcases Freescale’s Cortex-A9-based i.MX6 SoC.

Seco has released a commercial SBC spun from the original i.MX6-based open spec Udoo hacker SBC, adding eMMC flash and subtracting Arduino compatibility. Seco oversees the popular, community-backed Udoo SBC project, but also sells more commercial single board computers under its own name, such as the SECOpITX-GX.

If you've spent any time around UNIX, you've no doubt learned to use and appreciate cron, the ubiquitous job scheduler that comes with almost every version of UNIX that exists. Cron is simple and easy to use, and most important, it just works. It sure beats having to remember to run your backups by hand, for example.

Android L introduced a great new feature: the ability for a single app to have multiple tasks available on the 'Recent Apps' list. This is called Document Centric apps (Concurrent Tasks). In fact, this feature is a rather significant change in multitasking model in Android L, where focus has been shifted from traditional app-centric multitasking […]Continue reading...

GNOME 3.16 was released on March 25, benefiting from the contributions of 1,043 authors that made 33,525 changes.

Typically when a network is under my control, I like my servers to have static IPs. Whether the IPs are truly static (hard-coded into network configuration files on the host) or whether I configure a DHCP server to make static assignments, it's far more convenient when you know a server always will have the same IP.

Open source communities have always been my place to learn. read more

HAProxy(High Availability Proxy) is an open-source load-balancer which can load balance any TCP service. HAProxy is a free, very fast and reliable solution that offers load-balancing, high-availability, and proxying for TCP and HTTP-based applications. It is particularly well suited for very high traffic web sites and powers many of the world's most visited ones.

EMAC’s “SoM-A5D36? COM runs Linux on a Cortex-A5-based Atmel SAMA5D3 SoC, and offers up to 4GB flash, industrial temperature, and an optional carrier board.

I was invited to the second Picademy back in July. The first day was workshops, education, and the second day was a pure hack day, and we had a bit of a chat with Eben [Upton] and some other people who wanted to support and build something. We wanted to come up with something you could physically use, and we decided to use Scratch GPIO.

Google has open-sourced something called “gRPC” that it says represents “a brand new framework for handling remote procedure calls” using HTTP/2. The Chocolate Factory says it has dogfooded gRPC on its own microservices and that it “enables easy creation of highly performant, scalable APIs and microservices” and offers “bandwidth and CPU efficient, low latency way to create massively distributed systems that span data centers, as well as power mobile apps, real-time communications, IoT devices and APIs.”

GE unveiled a rugged COM Express Type 10 Mini module that runs Linux on a 2GHz Tegra K1 and offers soldered 2GB RAM and support for CUDA and VisionWorks. GE’s Intelligent Platforms business, a division of GE Energy Management headquartered in Charlottesville, Va., is primarily focused on the military/aerospace segment. The 84 x 55mm mCOM10K1 computer-on-module, which conforms to the COM Express Type 10 “Mini” form factor, is designed in part for SWaP-constrained mil/aero applications like image and video processing, sensor processing and electronic warfare. However, it also has broader applications in industrial Internet and Internet of Things applications, says GE. These are said to include industrial process automation, automotive and transportation, and medical imaging.
