Got my OLPC machine yesterday
Way back in November, I jumped at the chance to get one of the OLPC machines. For a small contribution and some waiting time, I would get my very own OLPC laptop (yes, I know that is redundant).
So, I cracked it out of the box and fired it up (like any geek) and here is what I have found:
1) I did not get one with a power crank :-( Mine has a wall wart (in a bright green colour).
2) The keyboard is SMALL. Now I am not talking about Palm or Blackberry small, but it is SMALL. Smaller than the Happy Hacking keyboard and the keys are ruggedized, so they are a little tricky to work. Still, I expect I will get used to them.
3) It only has a gig of "disk" which I suspect is actually solid state. Of course, it also has three USB ports and an SD RAM slot, so that should not be much of an issue.
4) The version of Linux on it is custom but RPM based.
5) It has cute graphics, but also has a full terminal.
6) It has what looks like a full colour screen, but works mainly in black and white when you are not actually using something in colour (battery reasons maybe?
It has cute little "bunny" ears for wi-fi that also act as the catches to keep the screen closed, and the screen is on a full swivel (it has to be to get at the SD slot).
I have not gotten the wi-fi configured yet and it does not have any other network connection. I do not think it is a touch screen but I have to tinker around with that.
I will keep you updated as I play with it more. Feel free to shoot your questions over and I will answer as best I can!

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
