|Daemon News tells us how to
boot FreeBSD 5.0 on a Sun machine over the network.
"To allow developers to test their code, especially disk drivers, it is necessary to boot the machine without using a disk. The FreeBSD Handbook describes the procedure for booting a diskless workstation, but that does not entirely apply to booting a FreeBSD-sparc64 system on a machine such as an Ultra 2. The solution below involves using TFTP and the kernel support for a NFS-mounted root partition to boot FreeBSD from the network."

|Linux Journal talks about
"Many users of open-source software are frightened by the term ``derivative works''. They worry they might accidentally create derivative works and put their own proprietary software under an open-source license. This is a complex topic that courts and lawyers disagree on, but I think we find definitions to ease people's concerns."

|The Basics of Linux Network Security|
|Linux Planet talks about
Linux network security.
"You might take a look at running a hardware firewall appliance. These devices are small routers or switches that have built-in firewalls. They generally allow limited setup of rules to allow packets to pass back and forth. They don't provide as much flexibility for rules as dedicated Linux firewalls."

|Synchronizing Networks with NTP|
|O'Reilly tells us how to
synchronize networks with NTP.
"An NTP primary server, or stratum 1, is connected to a high precision reference clock and equipped with NTP software. Other computers (stratum 2s), equipped with similar software automatically query the primary server to synchronize their system clocks."

|The Lives and Death of Moore's Law|
|First Monday brings us:
The Lives and Death of Moore's Law.
"Moore's Law has been an important benchmark for developments in microelectronics and information processing for over three decades. During this time, its applications and interpretations have proliferated and expanded, often far beyond the validity of the original assumptions made by Moore. Technical considerations of optimal chip manufacturing costs have been expanded to processor performance, economics of computing, and social development. It is therefore useful to review the various interpretations of Moore's Law and empirical evidence that could support them."

|Red Hat Beta (Phoebe) Preview|
|Extreme Tech brings us:
Red Hat Beta (Phoebe) Preview.
"Now for the really cool, new features of Nautilus. The first is built-in archiving. You can highlight a group of files, right click them and click "add to archive". You then type the name of the zipped file and add an extension for the type of file you want it to be and click ok. Thats it! The file extension choices are; zip, tar, tgz, and tar.gz."

|Linux Journal takes a quick look at the
Bootable Business Card.
"Had this been an actual Linux emergency, you could really use the LNX-BBC rescue disk right now. Here's how to test the
new release and make sure this mini-distribution has what it needs to rescue your system in the future."

|Essential System Administration Pocket Reference|
|Daemon News reviews the book
Essential System Administration Pocket Reference.
"Recently published, a companion to Essential System Administration, 3rd Edition (reviewed this month) is a quick pocket reference for the command, tools and important topics that can be found in the full book. Since it was done after the release of the full book, the round-up of the covered operating systems has been updated, with the exception of HP/Compaq Tru64 (or Digital) UNIX, to include the latest versions.

|Tuning Red Hat for Maximum Performance|
|This tutorial details the ins and outs of transforming a stock, "out of the box" Red Hat installation into a finely tuned, stable system customized to individual needs and tastes. The material presented here is based on Red Hat 7.3, although many of the techniques and procedures discussed are equally applicable to other mainstream Linux distributions.

"Still, it might be most appropriate to rename Red Hat to Midnight Grey Hat (Black Hat is taken), as the company announced a first ever profit in its latest quarter. That's right, the company best known for the mysterious guy in the red Fedora is no longer in the red."

|Getting a Handle on Traffic|
|Linux Magazine talks about building our own web server
"Unfortunately, most tools can't answer all those kinds of questions out of the box. To answer those questions, you typically need to extend an existing tool, write your own tool, or spend some quality time with awk, grep, and wc.
Or, you can turn to LAMP. By combining Linux, Apache (and mod_log_sql), MySQL, and PHP, you can build a customized logging and reporting system without a lot of effort."

|Linux Number Crunching|
|Coyote Gulch tells us about
benchmarking compilers and languages for ia32.
"I started writing this benchmark article with a singular goal: understanding how to get the most floating-point performance from my Intel-architecture Linux systems. Then the question arose of "Which programming language should I use?"; shortly thereafter, I asked myself "And whose compiler should I use?" And, of course, I was also curious about performance on hyperthreaded and multiprocessor computers... ...hence this article, which covers more bases than the New York Yankees."
