Letters to the Editor
What a pleasure to read Mr. Iacona's introductory treatment of awk in the June issue. I've been exposed to awk in a hard-core UNIX setting (designing SRAM circuit layout for Motorola), but have not used it myself. Now I design textiles on the SGI platform (not so far from chip layout as you might think) and need to manipulate text files. I run LinuxPPC on my PCC PowerCenter 120 Macintosh clone at home to practice UNIX for work. I'll lean on Mr. Iacona's article, his clear, well-commented example code and helpful glossary with confidence. I'm dying to get the O'Reilly books and take on more. A clear, usable, focused treatment of a daunting subject; well-edited, too. Continue to set your standards high.

The information in this month's Kernel Korner (“IP Bandwidth Management” by Jamal Hadi Salim, June 1999) reminds all of us that there is yet another dimension to the “free-ness” offered to Linux users: not only the code and applications in development, but also Linux ISP's.
These ISPs are affecting our ability to move freely. Why? QoS (Quality of Service) is essentially the end of all-you-can-eat Internet access—no more monthly flat rates. Oh sure, there's the bare-bones rate, but that's bare, bare bones. Instead, the more we are willing to pay, the more our ISP will shove down our lines. What a fair world!
It's a double-whammy. I can remember the good old days (i.e., three years ago) when we criticized telco's for ripping us off (after all, the customer is considered “the last mile”); now, ISP's will also be subject to our scorn (if they're not already), as will the host client/servers (i.e., those Linux boxes we adore so much).
Sure, QoS implementation is not so much a question of “if” but “when” (it's that inevitable, my friend). But my teeth gnash at the thought of this implementation hard-coded into the Linux kernel.

I've been a subscriber for a few years but still consider myself a newbie. So far, my faltering steps toward ever greater Linux mastery are consistently rewarded by finding out just how rich and robust an OS Linux is. Your magazine really helps; it's great to feel like I'm part of such a community as LJ serves. Thank you and your staff for sweating the little stuff.
