Wanted: a Mobile Home Cell
Ever wanted to improve AT&T wireless service? Yah, me too. Many times. Well, seems you can with a "personal 3G mini cellular tower" from Cisco. As Jamie Neary of Cisco blogs it,
Are you having issues with AT&T 3G coverage at your house? If you are then you’ll be very interested in this new offering from AT&T and Cisco. It is called a 3G microcell. The 3G MicroCell acts like a personal mini cellular tower (for voice and data) in your home or small business. It is a Cisco device that plugs into AT&T’s cell network and into your broadband service provider to provide a small 10 device 3G MicroCell at your house. And it supports up to 4 simultaneous users. How cool is that!
In a nutshell, the Cisco device (it is actually a Scientific Atlanta box) sets up a mini 3G cell of around 5000 sqft. Then it wraps up your cell call in IP and transmits it through your broadband Internet provider back to an AT&T POP.
It lets you move seamlessly from home cell to neighborhood cell. It doesn't screw with your unlimited data plan, if you have one. (Which I do.) And it works with any AT&T phone, including the iPhone. (Which is a clever thing, but not the world's best phone. I know, because I have one.)
Think of it as a VoIP bridge inside your end of AT&T's mobile network.
It's not here yet, of course. No price. Engadget mentions a "service plan," which is a depressing prospect.
Meanwhile, I'm thinking I want a portable one. I mean, wouldn't that make more sense? There's a lot of broadband laying around. Not just at your house, but at your friends' houses, at hotels, businesses, schools...
So then we get to my next point. If we can imagine extending the cell network over IP, why isn't the cell network itself an all-IP thing to which anybody should be able to attach any data device? Why, other than the obvious business, sunk costs and regulatory reasons, aren't we building something really new and creative here?
At some point a bit will flip and everybody will slap their foreheads in complete realization that it makes more sense to run voice on a data network than vice versa. And for that data network to be as open as possible.
Betcha AT&T would make more money if it was.

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
