Analyzing I/O Performance In Linux  View Printable Version 
Monday, April 26 2010 @ 11:44 PM CST
Contributed by: Linegod

General NewsMonitoring and analyzing performance is an important task for any sysadmin. Disk I/O bottlenecks can bring applications to a crawl. What is an IOP? Should I use SATA, SAS, or FC? How many spindles do I need? What RAID level should I use? Is my system read or write heavy? These are common questions for anyone embarking on an disk I/O analysis quest. Obligatory disclaimer: I do not consider myself an expert in storage or anything for that mater. This is just how I have done I/O analysis in the past. I welcome additions and corrections. I believe itís also important to note that this analysis is geared toward random operations than sequential read/write workloads.

Blast from the past - eComStation 2.0 GA is near  View Printable Version 
Saturday, April 24 2010 @ 06:34 PM CST
Contributed by: Linegod

General NewsAfter a long delay, eComStation 2.0 GA will finally become reality. It will be released in time to be presented at the Warpstock Europe 2010 event which is held in Trier, Germany, from May 14 to 16.

We consider eComStation 2.0 to be the biggest overhaul of OS/2 so far. Together with a team of both hired and volunteer developers, we have extended the functionality, removed limitations, updated hardware support as far as possible, and resolved close to 1000 issues that had been reported since the release of eComStation 1.2R. The new eComStation 2.0 GA is the result of several years of combined efforts and investments.

Dive Into Python Must Die  View Printable Version 
Friday, April 23 2010 @ 07:08 PM CST
Contributed by: Linegod

General NewsDive Into Python is one of the worst books for learning Python and it must die. I've had too many potential programmers find this book and get tripped up by its horrible design decisions that I'm declaring war. The book is weird, uses antiquated technology, has horrible examples, and Mark Pilgrim is too much of a neckbeard ass to listen to anyone about it:

The Perils of Sudo With User Passwords  View Printable Version 
Friday, February 26 2010 @ 12:26 PM CST
Contributed by: Linegod

General NewsThe consensus among new Unix and Linux users seems to be that sudo is more secure than using the root account, because it requires you type your password to perform potentially harmful actions. In reality, a compromised user account, which is no big deal normally, is instantly root in most setups. This sudo thinking is flawed, but sudo is actually useful for whatís it was designed for.

Thursday, February 11 2010 @ 09:36 AM CST
Contributed by: Linegod

General NewsWhen you use a system often, you tend to fall into set usage patterns. Sometimes, you do not start the habit of doing things in the best possible way. Sometimes, you even pick up bad practices that lead to clutter and clumsiness. One of the best ways to correct such inadequacies is to conscientiously pick up good habits that counteract them. This article suggests 10 UNIX command-line habits worth picking up -- good habits that help you break many common usage foibles and make you more productive at the command line in the process. Each habit is described in more detail following the list of good habits.

Web site monitoring techniques and tools  View Printable Version 
Friday, February 05 2010 @ 03:58 PM CST
Contributed by: Linegod

General NewsWhen monitoring a Web site, you need to look at it both from a 'micro' perspective (i.e. are the individual devices and servers in your infrastructure running smoothly?) and from a 'macro' perspective (i.e. do your customers have a pleasant experience when accessing and using your site?; can they use your site's functionality to conduct their business online?). You can also think about these types of monitoring as 'engineering' monitoring vs. 'business' monitoring.
