Unix+clones Considerations for the system architect: Performance
Post date: April 20, 2005, 06:04 Category: Miscellaneous Views: 86
Tutorial quote: For many developers and engineers, performance is often an afterthought. But when a product functions as designed and has proven stability and the right feature mix, success in the marketplace often depends upon performance. Architectural decisions define the ultimate feasible performance of any product. In this article, learn how performance-monitoring technology initially developed for mainframes can help you improve your own code's performance.

Linux HOWTO backup your linux system using bash, tar and netcat
Post date: April 2, 2006, 18:04 Category: System Views: 28
Tutorial quote: I recently ran into the problem of not having enough hard drive space on my slackware linux laptop, but was lucky enough to have a much bigger drive sitting around from before and wanted a way to perform a hassle free seamless upgrade. i had this idea and it worked pretty well so i thought i would share it since i think it's pretty cool and only requires the use of two tools that should be included with all distributions.
Debian Speedup DNS requests with a local cache
Post date: April 26, 2006, 05:04 Category: Network Views: 12
Tutorial quote: One common server bottleneck is DNS lookups. Many common server tasks such as from looking up hostnames to write Apache logfiles and processing incoming mail require the use of DNS queries. If you're running a high-traffic system it might be useful to cache previous lookups.
Linux Benchmarking Maildir Delivery on Linux Filesystems
Post date: April 12, 2005, 03:04 Category: Benchmarks Views: 65
Tutorial quote: The goal of this set of benchmarks is to determine which of the leading Linux filesystems (ext2, ext3, ReiserFS, and XFS) offer the best performance when used for accepting maildir deliveries. The resulting system should be a good balance of delivery and retrieval performance under potentially high concurrent filesystem load.
Unix+clones DNS name serving through NSD
Post date: July 5, 2005, 02:07 Category: Network Views: 80
Tutorial quote: Given the sheer importance of name servers in providing Domain Name System (DNS) resolution -- a process used by every Web-facing application to translate domain names into IP addresses and vice versa -- not many people put much thought into the available software alternatives for pulling off this feat. One compelling application is NSD, an alternative to the widely deployed BIND name server.

Linux Tuning up your IDE hard disks using hdparm
Post date: April 12, 2005, 14:04 Category: Optimizing Views: 80
Tutorial quote: hdparm is a tool for altering various parameters associated with IDE drives (Not SCSI). This involves things like the block prefetch, the DMA/PIO modes,
and a number of other things.

I'm writing this mini-how-to to help people get more from their system. People often complain that Linux is a bit slow for them (which it can be) I haven't seen such a post recently, but I know on TechIMO at least we always used to be talking people through using hdparm.
Unix+clones DNS Common Abuses
Post date: April 17, 2005, 05:04 Category: Security Views: 42
Tutorial quote: In paper I have present several features of DNS to make the reader familiar with the basics of the Domain Name System. I have also covered several well known and wide spread attacks that are used to exploit DNS. These attacks are by no means theoretical. In truth they grow more and more common as attackers become more sophisticated. The suggested defense methods outlined at the end of each section cover only the basic recommendations that can be used to thwart attackers.
Unix+clones Teach Yourself Perl 5 in 21 days
Post date: November 24, 2005, 15:11 Category: Programming Views: 72
Tutorial quote: No previous programming experience is required for you to learn everything you need to know about programming with Perl from this book.
