The data-logger expert Onset has expanded the capabilities to its HOBO U12 line, which now can measure and record kilowatts, air velocity, gauge pressure, differential pressure, DC current and other energy and environmental parameters. Onset attributes this new functionality to a new, compact power adapter, which enables energy and building management professionals to power external sensors that require 12-volt A/C excitation power conveniently. The new functionality augments existing measurement parameters, such as air temperature, relative humidity, light intensity, AC current and AC voltage. HOBO U12 Data Loggers also can record data unattended for up to months at a time, storing up to 43,000 measurements. Using a USB connection, HOBO U12 data loggers offer convenient, high-speed data offload directly to a computer or to a HOBO U-Shuttle data transport device.
The authorial threesome Dave Gray, Sunni Brown and James Macanufo have just released an interesting new book, Gamestorming: A Playbook for Innovators, Rule-Breakers, and Changemakers. The subtitle indicates that the book is targeted squarely at us—that is, “people who want to design the future, to change the world, to make, break and innovate.” The book's premise is that 200 years of industrial habits are embedded in our workplaces, our schools and our system of government, and certain strategies are required to make the changes necessary to “win in the 21st Century”. Gamestorming is full of practical solutions that help one engage people in a project, to get better traction and move more quickly with groups, to make things happen and get better, faster decisions and results.
No Starch Press, publisher of Michael Kerrisk's 1,500-page book The Linux Programming Interface, bills the title as the “authoritative work” and “definitive guide to the Linux and UNIX programming interface”. Kerrisk, who is the maintainer of the Linux man pages project, presents detailed descriptions of the system calls and library functions that one needs in order to master the craft of system programming. He accompanies his explanations with clear, complete example programs. Some key topics include using signals, clocks and timers; creating processes and executing programs; writing multithreaded programs using POSIX threads; building and using shared libraries; performing interprocess communication using pipes, message queues, shared memory and semaphores; and writing network applications with the sockets API.
SugarCRM hopes to (warning of sugar metaphor ahead) sweeten up the CRM space with Sugar 6, the latest edition of the company's flagship CRM system. The buzz around Sugar 6 involves its integration of social-media tools, such as Twitter, Facebook and LinkedIn, directly within the user interface. Users now can listen, monitor and aggregate social data and tie it to their existing customer information in a simple yet highly structured manner.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
