Headius: My Thoughts on Oracle v Google

This is a long article with some useful comments on the history of Java and the details of the patents in dispute.

http://blog.headius.com/2010/08/my-thoughts-on-oracle-v-google.html

Now we come to the biggest question of all: how does this suit affect the Java world, regardless of outcome?

Well it's obviously not great to have two Java heavyweights bickering like schoolchildren, and it would be positively devastating if Android were obliterated because of this. But I think the real damage will be in how the developer community perceives Java, rather than in any lasting impact on the platform itself.

Let's return to some of our facts. First off, nothing in this suit would apply to any of the three mainstream JVMs that 99% of the world's Java runs on. Hotspot and JRockit are both owned by Oracle, and J9 is subject to the Java specification's patent grant for compliant implementations. The lesson here is that Android is the first Java-like environment since Microsoft's J++ to attempt to unilaterally subset or superset the platform (with the difference in Android's case being that it doesn't claim to be a Java environment, and it may not actually need the patent grant). Other Java implementations that "follow the Rules" are in the clear, and so 99% of the world's use of Java is in the clear. Sorry, Java haters...this isn't your moment.

CDT - The Clojure Debugging Toolkit

http://georgejahad.com/clojure/cdt.html

> The CDT, (Clojure Debugging Toolkit,) is a set of clojure functions/macros that use the Java Debug Interface, http://java.sun.com/javase/6/docs/jdk/api/jpda/jdi/index.html, to debug a remote vm, from a repl running on another vm.
>> You can set breakpoints, catch exceptions, examine the stack frame/locals; what makes it unique, (afaik,) is that you can eval arbitrary clojure forms in the lexical scope of a suspended, remote-thread's stack frame.

So here is a quick reference to all core operations - core API, special forms, reader macros and Java interop - in Clojure 1.2.

http://mmcgrana.github.com/2010/07/develop-deploy-clojure-web-applications.html

The post walks through the process of developing and deploying a simple web application in Clojure. After reading this you should be able to build your own app and deploy it to a production server.

cljr

http://github.com/liebke/cljr

Cljr is a Clojure REPL and package manager. It’s designed to complement the project-oriented approach of dependency management systems likeLeiningen and Maven, both of which are my preferred tools for managing traditional-project dependencies. However, much of what I use Clojure for, including Incanter-based data analysis, is not really project-oriented. In these cases, it is more convenient to have access to a REPL (and Swank server) backed by a global package-management system.

HDMI is Dead. Introducing HDBaseT Networking

HDMI is dead. How can we say this? Because we have seen the future and it is HDBaseT. HDBaseT technology runs over STANDARD Cat5e/6 cable and implements something it calls 5Play, an unrivaled feature-set that converges full uncompressed HD video, audio, 100BaseT Ethernet, and various control signals. Oh, it also transmits up to 100W of power - that's enough to drive a 37-inch TV. And it can extend up to 100 meters passively. HDBaseT has the bandwidth to support the highest video resolutions such as full HD 1080p as well as 3D and 2Kx4K formats. HDBaseT is the first to provide all-in-one connectivity, making it possible for a single-connector TV to receive power, video/audio, Internet and control signals from the same cable.

Finally, something I predicted a decade ago might actually happen.
