Letters to the Editor

Readers sound off.
We goofed!

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.

Logging more friends...

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.

Kind regards,

Linux Journal Escapes Disaster

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.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
