Gadges and Gadgets!
It's strange how often my essential tools of trade are readily dismissed as gadgets (mandatory usage being “mere gadgets”). The doohickeys that you cherish are, of course, totally pathetic in my eyes, revealing you as a “sharper image” slave to self-defeating, fashionable mechanisms. Price and pride of ownership (closely related, nay, tightly bound) have clearly blinded you to the rational basics that guide my purchases.
The origin of “gadget” is, as the more honest lexicographers say, orig. uncertain or etym. obscure. Some guess at the French gâchette, but this was originally the safety lock-catch on a door or pistol, a reference to security and hard to reconcile with our modern “mere” gadgetry. Later, gâchette moved to become the pistol's “trigger” (as in Elle a la gâchette facile, “She's trigger happy”) which is perhaps more cognate with current gadget usage (see Note). She clicks to conquer, opening car/garage/home doors and TV channels, and, replacing old-fashioned scholarship, clicks to access the webbed windows of opportunity. Losing your clicker (I risk a gender-switch) is gadget-impotence, akin to Milton's blindness. Fear not: there's a meta-gadget you can click that will locate (beep-beep) your misplaced clicker. Lord knows what deeper levels of technology exist for recovering lost meta-gadgets. And now that mice, keyboards, modems and monitors (more) are becoming footprint-loose, wireless “remotes”, there's a growing chance of mislocation.
My own amateur spin is that “gadget” has morphologically diminutive implications (easy for me to say) that have added to its derogatory usages. I would back-form the term “gadge” to describe my own solidly justified possessions, regardless of price, conversation-party-piece, physical size and weight.
We are, patient readers, converging to a topic relevant to Linux, the OS we all love. I refer to the test known as productivity, an apparently simple econometric criterion that should (fat chance) dictate all our choices. The TV gadget heyday ads of the 1950s and '60s showed a trim USA super-efficient Mum clicking breakfast for hubby and her 2.7 adorable kids, then clicking the washing up. The general mantra “labor saving” (since applied to all forms of automation) left open the questions, “Saved at what cost?” and “time saved to do what else?” There's the ancient Time & Motion quip: Expert: “If you follow our plan, you could paint twice as many fences.” Tom, the painter: “But there aren't twice as many fences to paint.”
The equation has been obscured by the more subjective notion of “personal productivity”, yet even at the corporative level, after endlessly refined techniques and “studies at well-known West Coast Universities”, it remains dubious whether we can ever well-order our choices of computer languages, operating systems, development methodologies or guiding columnists.
Except to assert that my gadges are the best.
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
