Hunting Penguins in the Desert: The CES Report
I missed a lot at CES, unavoidably. For example, it was hard to find Booth 22200 when the banners on the ceiling pointed to 22100-22175 on one side of the hall and 22300-22350 on the other. But there were fun places to pause between here and there. One was Nisus, which makes a little camera that shoots 4-megapixel still pictures, records and stores MP3s, shoots digital movies (even at VGA resolution) and costs just $199. They were doing brisk business at the booth when they weren't busy goofing around. The same went for the folks at NeuTrino Technologies, who have a complex and useful Windows-based desktop software product. I tried to convince them to re-deploy their stuff for Linux but didn't get my hopes up, even though it was clear they take Linux seriously.
It also was fun to see all the LCD and plasma TV screens, which generally looked impressive but continue to be priced way too high for most of the market--but not so high that the haven't made the market for conventional TVs, even "HDTV-ready" ones, terminal. That's why prices for old-fashioned picture-tube TVs are falling toward zero. If you're still into TV, now might be a good time to buy one. I saw in a recent Consumer Reports that the top-rated TV of any type, including plasma and LCD, was a Sony WEGA tube model. (The KV-34XBR910, to be exact.)
As you might guess from the photo galleries I publish along with articles like this one (see also, Linux Lunacy Geek Cruises (2001, 2002 and 2003); OSCon; Apachecon; and Digital ID World), photography is one of my preoccupations. In fact, I began my journalism career 33 years ago as a newspaper photographer and reporter. Since then my specialty has become candid photography, although I enjoy a nice sunset a much as the next lens wrangler.
But I've avoided getting a good digital camera; partly because they're still too expensive and partly because my practical needs are outside the scope of just about everything I've seen from the digital camera makers. For one thing, I shoot a lot of presentations at trade shows and other events (such as Linus' talk on the last Geek Cruise), and I need a long zoom lens to get tight shots of presenters and presentations (an enormous help for note-taking). I also shoot a lot of candids that take advantage of the flip-out viewers that are standard on camcorders and increasingly rare in digital cameras.
My base requirements are simple: 1) long zoom, 8x optical at the minimum; 2) flip & pivot display; 3) small size, so it's easy to carry in a laptop bag or a large pocket; and 4) ability to shoot good pictures in low light. High resolution is nice to have, but not it's not a prime necessity.
So far, the only cameras that do all four of those things have been camcorders that also shoot stills. That's what you see in the archive links above. Most of those were shot with my Sony DCR-PC120BT or its stolen predecessor, the DCR-PC110 (nearly identical, except for the 120BT's BlueTooth, which, in the Sony tradition of hideous UIs, is unusable). The resolution is only 1.55 megapixels, but most of the time that's good enough for the Web. Its built-in processing has a lot of compression artifacts and the color is far from the best. But the Zeiss optics are excellent, and on the whole it does a good-enough job.
At both Macworld and CES I stopped by the Olympus, Canon and Nikon booths to see what they had this time around. The only camera that came close to meeting my needs was the Nikon Coolpix 5700. I loved the way it felt and the size, which is smaller than it appears--it's almost pocketable. But it's still a lot of money I don't have, so I think I'll wait.

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
