Letters to the Editor
Just a note about a type-o in your March 1995 Kernel Kornel. On page 52, column one, paragraph 4.
You use request_irq() instead of request_dma() and you wrote “IRQ channel” instead of “DMA channel”.
I don't think this caused any confusion because it is evident that you were talking about DMA.
Anyway, just thought I would bring this to your attention. Besides it gives me a chance to say keep up the good work.

Michael Responds: ACK! You are absolutely right. Mea culpa.
I've read the System Administration article (“How to log friends...”) in the March edition of Linux Journal and found it quite useful. But I think the following remark is useful, too: if the logging level is set to =something, i.e. =debug, then only messages with this level are logged.
By the way, the syslog configuration can be tested with “syslog_tst”, which I found in /usr/sbin on my Slackware 2.0.1-based system. I do not find a man page for it, and there is no mention of it in the syslog man page.

I am writing to inform you that my address has changed.
Basically, my house burnt down and I was forced to move. Fortunately all of my back issues of LJ were on loan to my scungy mates, who had not returned them for 3 months or so, and thus were not burnt.

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 The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model.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
