Emmanuel Dreyfus Interview
On Lamp talks to Emmanuel Dreyfus.
"If we want to run a binary on a processor it was not build for, then we have to emulate the CPU in software. This kind of thing has been done by Apple for their m68k to PowerPC transition. Emulating the CPU in software costs a lot, so it will give you reasonable performances only if the native CPU is much faster than the emulated CPU (which was the case for Apple's m68k emulator for the PowerPC, but it was an unusual situation)."

Python Cookbook
Unix Review reviews the book Python Cookbook.
"PC is, in fact, two books packed into something less than 600 pages. The recipes are certainly indispensable for a working Python programmer. A "Discussion" follows each one, in the usual O'Reilly Cookbook style. These Discussions are so meaty, eloquent, and well-informed that they could stand by themselves as a valuable course in software engineering."

Improving mod_perl Sites' Performance
Perl.com continues its series: Improving mod_perl Sites' Performance.
"It's desirable to avoid forking under mod_perl, as when you do, you are forking the entire Apache server -- lock, stock and barrel. Not only is your Perl code and Perl interpreter being duplicated, but so is mod_ssl, mod_rewrite, mod_log, mod_proxy, mod_speling (it's not a typo!) or whatever modules you have used in your server, all the core routines."

10 Linux Predictions for 2003
linux World brings us: 10 Linux predictions for 2003.
"It's the time of year when columnists make shots in the dark about what will happen in the next 365 days, and Joe Barr is no exception. Plus, we review how well Barr did last year. Editor's advice: Don't listen to his Super Bowl predictions."

Closing the Floodgate
Security Focus tells us about DDoS mitigation techniques.
"To be on the receiving end of a distributed denial of service (DDoS) attack is a nightmare scenario for any network administrator, security specialist or access provider. It begins instantly, without warning, and continues relentlessly: machines down, jammed bandwidth, overloaded routers. An effective, immediate response is often difficult and may depend on third parties, such as ISPs. With these challenges in mind, this article will explore some techniques that systems administrators and security professionals can employ should they ever find themselves in this rather undesirable situation."

The ELC's New Embedded Linux Platform Spec
Linux Devices tells us about the ELC's new Embedded Linux platform spec.
"The ELCPS was designed to be an API specification, thus supporting source level portability of applications to different implementations. This design ensures a specification that provides developers of applications and middleware assurance that their products can be recompiled for a large variety of potential embedded Linux targets."

SCO Linux 4
eWeek reviews SCO Linux 4.
"UnitedLinux members can set their distributions apart from one another by bundling separate front ends with the core components. For example, SCO Linux provides the open-source Webmin and Usermin system administration tools rather than the full complement of YAST (Yet Another Setup Tool) utilities that ship with SuSE Linux."

Sendmail Performance Tuning
Slashdot reviews the book Sendmail Performance Tuning.
"The next two chapters, 'Finding and Removing Bottlenecks' and 'Load Generation and Testing,' are good, solid, well-written sections that are applicable to most any email system. We are given some effective ways of making systems run better, and how to prove that the system actually does work better. This is where we justify to the boss that the work we have done is really cost effective."

CanIt Spam Trap
Unix Review takes a look at CanIt Spam Trap.
"So, it makes sense to deploy something that will block spam, and viruses, without dumping legitimate emails. One product that's worth a look is CanIt Spam Trap. CanIt is a product that tries to identify spam, and claims to "never discard a valid email message". I took CanIt for a test drive and here's what I found."

Installing Oracle 9i on Mac OS X
Mac Dev Center contines its series on installing Oracle 9i on Mac OS X.
" In Part One of this three-part series exploring Oracle 9i on Mac OS X, David Simpson provided some excellent background information and a look at the ramifications for Solaris administrators. In Part 2 he differentiated between FileMaker Pro and Oracle, with a side conversation about WebObjects. An overview of Oracle's pricing structure was also included. In this closing segment, he shows you how to actually install Oracle on Mac OS X."

No 'A' Word In Time
Linux Security brings us: No 'A' Word In Time.
"Most computer systems come with tools to assist in accurate time synchronization (time synch). Time synch includes maintaining the accurate time and date. Some distributions, like EnGarde Linux, come with XNTP, a Network Time Protocol (NTP) daemon, already running and ready to synchronize with external time servers."

Hacking Linux Exposed, Second Edition
Slashdot reviews the book: Hacking Linux Exposed, Second Edition.
"HLE on the other hand was much more like a good textbook -- it taught you how to think about security, to see how each problem was caused and how to combat them. As the years went by, my copy of HLE was still as useful as it was the day I got it. For this reason, I was skeptical what they could put into a second edition -- the first seemed to stand the passage of time just fine."

SGI Busts into Linux with 64-Processors
Linux Planet tells us about SGI's new Altix 3000.
"SGI, which has long been in the business of high-performance computing for technical and media clients with its IRIX operating system on MIPS processors, decided that it would capitalize on the same architecture the company uses to create 1,024-processor IRIX Origin 3000 servers. This architecture, known as NUMAlink, allows data to be shared between separate machines with only a negligible performance hit, compared to multiple processors on the same machine."

Humor In Kernel Code
Kernel trap tells us about some funny Linux kernel code.
"> egrep -ir "(on fire)" *

drivers/usb/printer.c:static char *usblp_messages[] = { "ok", "out of paper", "off-line", "on fire" };"
