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.
The recent brewing going on at enStratus has resulted in a new edition of its self-titled suite of tools for managing cloud infrastructure that now includes VMware's vSphere. With this expanded support, customers can leverage a unified solution to manage vSphere as well as private and public cloud infrastructures. Features that customers now can leverage in a vSphere deployment include self-provisioning, advanced user management, financial controls and automation. In addition to supporting vSphere and vCloud Express from VMware, enStratus also supports leading cloud infrastructure platforms from Amazon Web Services, Eucalyptus, GoGrid, Rackspace, Cloud.com, ReliaCloud, Terremark and Windows Azure.

Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

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
