Current_Issue.tar.gz - The Kyle Rankin Issue (He Wishes!)
Back when we were creating the editorial calendar for 2009 and decided on “Hack This” as the topic for October, I think our resident Hack & / columnist Kyle Rankin thought that issue was going to be dedicated completely to him. (Either that, or he was a bit worried we'd make him write every single article in the issue.) As it turns out, neither was true. I considered telling him we needed enough content from him this month to fill the magazine, but to be honest, Kyle scares me a bit. So, I saved my joking for this piece.
Just because our Hack Editor didn't write every jot and title this month doesn't mean we won't leave as better hackers. Duilio J. Protti gets us going with low-level system programming, but we don't use an actual system. Thanks to KVM, we learn low-level system hacking on a virtual machine. Virtual machines are so robust nowadays, the concepts and practices will work on a real system too. If software hacking isn't enough for you, fear not. Marco Fioretti shows us some actual hardware hacking with Field Programmable Gate Arrays. You won't need to break out a soldering iron, but it'll just about feel like it!
If all this system hacking sounds fun, but you're worried your proprietary computer BIOS will hinder your skills, Anton Borisov might be just the man you want to listen to. He shows us the ins and outs of coreboot (you may know it as LinuxBIOS). Although flashing the firmware on off-the-shelf routers might be second nature, not too many of us have ventured into BIOS flashing. It seems a perfect fit for this issue.
If you've hacked your computer so that it bends to your every whim, you definitely want it to look cool as well. Sure, Compiz on your desktop will draw oohs and ahhs from the occasional Windows user, but even Linux users will be impressed if you implement Clutter in your programming. Clutter allows you to add rich, GUI interfaces to your applications quickly and easily. Alex Crits-Christoph demonstrates utilizing Clutter's advanced toolkit. In fact, we've got a bunch of programming hacks this month. Reuven M. Lerner talks more about testing with RSpec for Rails, and Dave Taylor shows us some cool (and $RANDOM) Web server tricks.
And, of course, the “Kyle Rankin” issue wouldn't be complete without his monthly Hack & / column. This time, Kyle shows us his secret to fighting spam (and its only slightly more palatable cousin, e-mail ham) preemptively. We all have a handful of “throw-away” e-mail addresses we use when signing up for something on-line, but Kyle uses a different address every single time. So while Kyle shows us how to keep unwanted things out of our inboxes, his buddy Bill Childers demonstrates how to put things we might want (namely Android) in some bizarre places. A few months back when the editorial team was talking about content for this issue, I challenged him to install Android on his Netbook. He rose to the challenge, and not only got Android running on his Netbook, but also on a Windows Mobile phone!
We have a full lineup of articles on other topics as well. Whether you are looking for desktop security tips from Mick Bauer, new product information from James Gray or a rally cry to take over the Internet from Doc Searls, you're gonna love his issue. Heck, even I get into the hacking act with Google Voice. You might be able to get unlimited minutes on your cell phone thanks to a handy little trick with your free GV phone number. So for this month, we all got to be hacks. You can too. And if you become a hacker, don't worry, we won't tell Kyle. We wouldn't want him to get jealous.

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
