Java: When segments collide

  Submitted by Frank Java 3 Comments
While sizing the heap for 32-bit Java applications on AIX, you can sometimes run into situations where a segment is claimed by two or more parts of the process simultaneously. This article shows how to detect this situation by using a well-established set of applications as examples, and we also show the reasoning behind the configuration changes suggested to avoid this situation.

Review: theKompany Black Adder Python IDE

General Development 19 Comments
Before beginning, I must offer my profuse apologies to Shawn Gordon and the rest of theKompany crew. Shawn sent me the Black Adder software several months ago; however, my schedule ballooned beyond all believable bounds and has stubbornly maintained that ludicrous pace; unfortunately. I have not had an opportunity to write this review until recently, so I am sorry for my tardiness. And now to answer the most obvious question; what is Black Adder?

Emulating RISC OS under Windows

RISC OS 20 Comments
One of the most impressive aspects of even relatively modest PC hardware is its' ability to emulate a wide range of other platforms. Being a bit of an OS junkie myself, and lacking the space for a full computer room of weird and wonderful hardware, I emulate a range of systems from my humble desktop PC. In this article, I will describe the procedure through which you can run RISC OS 3.7 and others on a Windows-based PC and experience this classic OS (screenshots included).

Will Red Hat Take Linux to Enterprise Heights?

Red Hat 31 Comments
"From a strictly technical standpoint, Red Hat ES isn't particularly noteworthy: It's a collection of software compiled and packaged up, given a few management tools of varying quality, and pushed out the door. We did not notice any functionality unique to this Linux distribution, and there are certainly others out there that could fill the role of "departmental server" with equal facility for a lower price."

Fixing the Java Memory Model

Java 25 Comments
JSR 133, which has been active for nearly three years, has recently issued its public recommendation on what to do about the Java Memory Model (JMM). Several serious flaws were found in the original JMM, resulting in some surprisingly difficult semantics for concepts that were supposed to be simple, like volatile, final, and synchronized. In this installment of Java theory and practice, the author shows how the semantics of volatile and final will be strengthened in order to fix the JMM. Some of these changes have already been integrated in JDK 1.4; others are slated for inclusion in JDK 1.5. On other Java news, IBM urges Sun to make Java open source.
