DevelopmentTurn-Key Linux Audio The Eastman Computer Music Center has released their Turn-Key Linux Audio installation package."Turn-Key Linux Audio is a scripted installation package for the core set of linux audio applications used at the Eastman Computer Music Center (ECMC). It contains among its many tools over a decade's-worth of powerful shell scripts, smart aliases, tutorials, documentation, shell level environment variables for multi-media linux/unix workstations, and a library of powerful templates and macros (Csound, Score11, SMS, PVC, Rt, Vspace, etc) created by composer, teacher, and ECMC director Allan Schindler." Turn-Key Linux Audio is designed to install on the Mandrake 9.0 distribution. The Installation instructions appear to be fairly straightforward, involving the download of a tar file, and execution of an install.sh script from a root account. The installation script is designed to streamline the process of adding a big collection of audio software to the system, it handles the time consuming and sometimes difficult task of managing package dependencies. Turn-Key Linux Audio provides a wide variety of popular open-source software tools. The software categories include Sythnesis/Composition, Players/Recorders, Mixing, Utilities/Other, and a large number of scripts that address common audio processing needs. Some popular packages that don't show up in the software list include: The Festival Speech Synthesis System, compression utilities like Ogg Vorbis and mp3, and drum machines such as Robert Muth's Trommler. However, with the incredible list of available software, a few omissions are understandable. The Turn-Key documentation includes a typical set of package documents as well as a list of useful links to the many audio components that are part of the system. The Turn-Key FAQ is still fairly short at this point in time. One important question that doesn't appear to be answered is: "how much disk space does a full Turn-Key installation require?". Participation in the Turn-Key project is being encouraged, audio software writers may find it to be a useful way to get their wares into wider use.
System Applications Audio Projects GStreamer 0.5.0 released Version 0.5 of the GStreamer streaming-media framework is out. "This release has mainly focused on code clean-up and rounding out of the features. Large chunks of GStreamer are API stable at this point."

Audiality 0.1.0 released Version 0.1.0 of Audality has been released. "Audiality is an audio engine originally designed for playing music and sound effects in games. It is designed from the ground up with real time operation in mind, which means that it can take advantage of real time scheduling on operating systems that support it, for fast response and reliable output. That means that with a suitable operating system, you can play Audiality like a MIDI synth, with no more latency than a well designed hardware synth." The main news is the creation of an Audality web page.

Top Five Open Source Packages for System Administrators (O'Reilly) Æleen Frisch covers Nagios (formerly called Netsaint) in part four of her series on open source packages for systems administration. "The second place in my top five tools list goes to Nagios, written by Ethan Galstad. Nagios is a feature-rich network monitoring package. Its displays provide current information about system or resource status across an entire network. In addition, it can also be configured to send alerts and perform other actions when problems are detected. This week, we'll look at the sort of monitoring that Nagios provides and also briefly discuss configuring the package."

Improving mod_perl Sites' Performance: Part 5 (O'Reilly) Stas Bekman continues his series on optimizing mod_perl performance with part five. "As we have learned in the previous article, sharing memory helps us save memory with mod_perl, giving us a huge speed increase; but we pay the price with a big memory footprint. I presented a few techniques to save memory by trying to share more of it. In this article, we will see other techniques allowing you to save even more memory."

Languages and Tools C++ [C++ PATCH]: Covariant returns Nathan Sidwell has contributed a patch for GCC that implements covariant return thunks. "Covariant thunks are represented much like ordinary thunks, except that they themselves can be thunked to. A this-pointer adjusting covarient thunk looks like a this-thunk to a covariant-thunk to a base function. I tidied up the naming of the thunk adjustment accessors to use fixed_offset and virtual_offset appropriately (rather than delta and vcall_offset)."

You'll develop sample code that uses JavaCC to build a custom parser, starting from a BNF description of the grammar."
Programming Jakarta Struts: Using Tiles, Part 4 (O'Reilly) Chuck Cavaness concludes his series on Jakarta Struts with part 4. "The tiles shown so far add value to an application because they organize the layout of a page in a single resource, the layout JSP page. This can save development time and, more importantly, the time it takes to change the layout for an application. However, there is a problem with the approach used in the Storefront application shown earlier. In each of the non-layout tiles, there is redundant code that specifies what content to use for the header, menubar, and copyright content--the same attributes are being passed in every page. This may not always be the case, but in general, these values will be constant throughout an application. For instance, the same copyright is typically shown on every page."

Generating One-Time URLs with PHP (O'Reilly) Daniel Solin shows how to generate one-time URLs in PHP on O'Reilly's ONLamp site. "Imagine that you're selling a digital product online. Maybe you've written an article or a book and want to sell it on your site as a PDF. There are many ways one could do this, but one of the more convenient is to provide the user with a unique URL that only will work a limited number of times. This URL could, for example, be presented to the user (your client) on the last page of an orderflow, after payment has been made. We will look at code to generate a unique URL that will work a single time."
