JACK Meterbridge 0.0.4

Version 0.0.4 of JACK Meterbridge has been released. A meter bridge is hardware assembly that typically involves a row of audio meters that "bridge" across the top of an audio mixing console.

JACK Meterbridge allows a number of software audio level meters to be displayed on screen. The meters plug into the JACK audio connection kit, a software package that manages multiple connections to audio devices.

Jack Meterbridge currently has a selection of three meter styles, two of them resemble classic mechanical meters, either peak-reading or classic VU style, and one that is a vertical bar-graph style.

Jack Meterbridge is a good example of a virtual hardware device that can be plugged in to JACK. No doubt, many other such devices such as oscilloscopes, spectrum analyzers, and tuners could be programmed to work with Jack. Hopefully, JACK will prove to be a good platform for developing a wide variety of new virtual audio devices.

Issue #111 of the AbiWord Weekly News is out. "This has certainly been a mixed week! With the new release of 1.0.3, a new meta-bug has been put in place. One example of things most recently caught, 4046 , where something went horribly wrong, and now spelling is all just fizzley if you're using the dialogue (right clicking individual words still works). The good news, however, is that Mark has already promised that 1.0.4 will come out much sooner compared to 1.0.3; preferably within a month."

G95 progress

Progress continues on the G95 FORTRAN compiler project. "Plan: Finish the type resolution phase. There are a few things that g95 cannot currently handle, but most of the simpler things are implemented. Conforming fortran 77 programs should be parsed and resolved without difficulty. I have uploaded a Linux x86 binary in order that non-hackers can try g95 on their favorite bits of code and can make sure that that parser doesn't choke too bad."

EJB Inheritance (O'Reilly)

Emmanuel Proulx writes about EJB inheritance on O'Reilly's ONJava site. The article is divided into part 1 and part 2. "Entity beans are objects that represent data coming from a persistent store, such as a database. The key word here is objects. Entity beans encapsulate the data and business logic. But what about the two other principles, inheritance and polymorphism?"

Genetic algorithms with Perl (IBM developerWorks)

Teodor Zlatanov writes about genetic algorithms with Perl on IBM's developerWorks. " One of the more intriguing types of algorithm is the genetic algorithm. Genetic algorithms mimic Darwinian natural selection, where "fitness" selects individuals for survival, breeding, and, hence, adaptive mutation. I covered the background on this in a previous column, and I also showed two Perl implementations, one that bred bytes and another that bred words. In this article, I cover more advanced material on genetic algorithms in Perl."

An AxKit Image Gallery (O'Reilly)

Barrie Slaymaker explains how to use AxKit to make an image gallery. "AxKit is not limited to working with pure XML data. Starting with this article, we'll work with and around non-XML data by developing an image browser that works with two types of non-XML data: a directory listing built from operating system calls (file names and statistics) and image files. Furthermore, it will be built from small modules that you can adapt to your needs or use elsewhere, like the thumbnail generator or the HTML table wrapper."

Introducing HLink (O'Reilly)

Kendall Grant Clark explains HLink on O'Reilly's XML.com. "On its face HLink is a very simple specification, even if, as Joe English and Tim Bray have noted, it amounts to a kind of rehabilitation of SGML's (infamously complex, as I recall) architectural forms extensions. The point of HLink is to provide a way of saying one or more of the following things: that (1) some elements or attributes within an XHTML markup language (or, better: within a namespace) are or can be treated as a hypertextual link; that (2) the functional semantics -- how the link behaves under various conditions -- are such and such; (3) that an attribute of some element which is a link has such and such an effect on its semantics."
