Next Up in Knickers: Mood Undies
As geeks, it's almost obligatory to want the latest and greatest technology on the market, no matter what it may be. There may well be an exception to that rule, however, if the latest out of UC San Diego catches on: digital drawers.
We're not entirely sure whether to file it under "amazing innovations" or "what were they thinking", but engineers at the University of California San Diego have developed underwear that can keep tabs on the wearer's vital signs from wherever they might be. Professor Joseph Wang — seriously, we couldn't make this up if we tried — says the bio-bloomers can currently monitor heart rate and blood pressure, but he hopes to expand their capabilities to track everything from stress levels to blood alcohol concentration.
The secret to Wang's success is in screen printing. Rather than simply building sensors in to apparel, as has been done in the past, Wang's undies have carbon electrodes printed onto the waistband, making them both comfortable to wear (reportedly) and highly durable. The printed panties are unaffected by stretching, folding, and other normal wear, he noted.
All jokes aside, the technology does hold a great deal of promise. Patients who would otherwise require hospitalization for monitoring/observation could be sent home under skivvy surveillance, reducing healthcare costs and congestion. Soldiers, athletes, and others under high stress could be tracked in a non-invasive manner, and if Wang's plans for future development come to fruition, the techno-unmentionables could find themselves in a whole host of locations.
For the moment, don't expect to find anything but low-tech lingerie at the local Walmart. Still, knowing geeks as we do, if Wang's undies take off, we suspect it won't be long until someone is developing a Linux distro with skivvy support or hooking their high-tech hotpants up to Twitter.
Indeed, a hard-hitting review might even find its way into the pages of Linux Journal. Should that happen, I nominate our lovely and talented Associate Editor, Shawn Powers, to give the techno tighty-whities a go — I would, but I wear boxers.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
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
