Distributing Your CA to Client Browsers
On Lamp tells us more about Certificate Authorities.
"In order for your client browsers to trust your new Certificate Authority, they must be configured to accept your CA's public key. There are two possible formats that browsers will accept for new certificate authority certs: pem and der. You can generate a der from your existing pem with a single OpenSSL command:"

Program Hides Secret Messages in Executables
Security Focus tells us about a program that hides secret messages in executables
"El-Khalil's research focused on redundancies in the Intel x86 instruction set -- places where at least two different instructions are effectively the same. Each choice between two redundant options can represent a single bit of data."

Comparison of Windows vs. Unix
Linux World looks at Unix and Windows.
"This article compares the Microsoft client/server architecture to the Unix approach in terms of systems decisions facing a university faculty. To put this in context, imagine that you are being interviewed for a job as the faculty's systems manager. The chairman of the selection committee asks you to come in to discuss whether the faculty would be better served if it went all-Linux instead of staying all-Microsoft."

Sun blade servers to use AMD chips
News.com reports that Sun blade servers will use AMD chips.
"Sun's first blade servers will have a single processor, though the company plans to follow rivals Dell Computer, Hewlett-Packard and IBM in launching dual-processor models, Sun has said. Those rivals--which also plan to release more powerful blade servers--use Intel but not AMD processors in their blade servers."

Building a Vector Space Search Engine in Perl
Perl.com tells us how to build a Vector Space Search Engine in Perl.
"In this article, I want to show you how to build and run a search engine using a vector-space model, an alternative to reverse index lookup that does not require a database, or indeed any file storage at all. Vector-space search engines eliminate many of the disadvantages of keyword search without introducing too many disadvantages of their own. Best of all, you can get one up and running in just a few dozen lines of Perl."

Alternative Nameservers
Unix Review takes a look at alternative nameservers.
"PowerDNS is an authoritative-only nameserver. This means that it will answer queries about zones that it is responsible for, but it won't attempt to find information on another zone/domain. For example, if you set up PowerDNS to handle "yourdomain.com," it won't answer queries for "mydomain.com" or "bobsdomain.com". This means that you don't have to worry about a poorly configured (or maliciously configured) server polluting your nameserver's cache."

Sysadmin Tales of Terror
Crossnodes brings us: Sysadmin Tales of Terror.
"The biggest challenge a system administrator ever faces is inheriting a networking mess: taking on a new job, or a new client, with a computing infrastructure that has grown without rhyme or reason. Lost passwords, little or no documentation, no-name network components, and cables snarled into alternate dimensions are just a sample of the evils to face and conquer."

Opera and Microsoft
Linux World tells us about Opera showing a graceful, humorous response to Microsoft blunder.
"Opera responded to this latest burst of incredible pettiness by Microsoft with a little humor, a lot of PR and a blow to the solar plexus. The humor came in the form of a "Bork edition" of the Windows version of Opera. When you visit MSN running the "Bork edition," it renders the page in the language of "the famous Swedish Chef from the Muppet Show: Bork, Bork, Bork!"

A Quick Guide to vi
O'Reilly brings us: A Quick Guide to vi.
"But what if you need to edit a file quickly in Terminal and don't have the time to learn and practice vi? In this article, I will present a quick guide to getting you started using vi. Do remember though, topics on vi are enough to fill an entire book, and hence this article is just a tip of the iceberg. Hopefully, it will shed some light on this powerful editor and tempt you to learn more."
