Open Source

I'm at OSCON in Portland, Oregon this week. I will be posting my notes here.

One of the Open Source Geospatial Foundation (OSGeo) email lists is reviewing relationship between OS and IP. Again. I am a big fan of matching license to community. While I recognise that open source and intellectual property can be considered as opposites - I find myself lumping them both together. Rather then recycling this viewpoint, here is a note to self (allowing me to supply a link): Note...

It's been two years since I posted here last, but life has been busy with open source all the same. Having helped a startup with their open source thinking, I'm now independent again and contributing much of my time to the Open Source Initiative (OSI) and to The Document Foundation (TDF), as well as offering open source policy and practice consulting. That first association with OSI is...

Recently there has been a renewed interest into the Actor programming model. The Actor Model actually comes from the '70s, but as far as I'm aware it has been used only in a very limited subset of industrial projects outside the area of telecoms. Erlang (not by chance developed at Ericsson, a telecom industry), which is a language whose concurrency model is actor oriented, is getting some...

I've just left a meeting where the PM congratulated the team because the customer accepted a product release that was made with three weeks in advance of the original plan. First, thank to the developers' team. Second, thank to the good development process (people and process are always the important things, more than technology). Third, thank to libraries and software factory, including...

Programming

Knuth-Morris-Pratt (KMP) Overview According to Wikipedia, the Knuth-Morris-Pratt algorithm "searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters". Being 'A' the...

A new tutorial that exercises VisualLangLab using all the examples and techniques in Chapter-3, A Quick Tour for the Impatient, of the book The Definitive ANTLR Reference can be found at this link. Various other improvements have been made in version 7: A new WildCard pseudo-token that matches any defined token has been added to facilitate recovery from errors...

This blog describes how to build both, a 64-bit and a 32-bit version of OpenJDK 8 on a plain, vanilla WindowsXP 64-bit operating system using only free (as in free beer) tools. body { font-family: arial, helvetica, sans-serif; font-size: 10pt; } caption.my { font-weight: bold; margin: 0px 0px 10px 0px; } span.update { font-weight: bold; color: maroon...

Concentrating on Task in Hand (similar to Mylyn) in NetBeans IDE Often we work on fixing a bug or developing an enhancement for an open source project maintained over a period of many years and having hundreds of source code files.  usually we need a handful of 5 to 10 source files to fix the bug or to add new enhancement.  The project explorer provided by IDE's like NetBeans IDE show...

With the release of version 6.01, VisualLangLab can support all -- present & future -- JVM languages.  VisualLangLab's approach of composing parsers at runtime by using combinator functions instead of generating code (as other parser generators do) enables these parsers to be embedded into a host program in any JVM language. Eschewing code generation also eliminates all host-language...

Project NBTaskFocus makes the automatic tracking of your opened editor files available in its alpha version.  It provides two panels named 'Task Explorer' to see your tasks and the activation state of the task, and 'Task Details' to see your tracked opened file context.  As soon as you open any file in editor of NetBeans IDE it is added to the activated task as its context. ...

I blog this, because shocked with Oracle's Corporate Fair new "program" in our area, Asia Pasific, and feel that our 12 years work is like never seen. Strange what Oracle doing in headquarter, and why all the Sun report from pre-acquzition never come to his office.. I am glad somone can send this blog to him. and change his "status" of this country, Indonesia to a better place...

    Nowadays the Enterprise applications beyond persist String and number also can save file. Persist this information is very interesting, for example, a civil process there are information about the process (name of author, date, number of protocol) and the document which represents, or a twett with an image. In Apache Cassandra, you can save file, but for large file you should use...

This article has the main objective show a little example for persist information in Cassandra using java. For demonstrated the persistence with Cassandra will used the Easy-Cassandra, a framework open source for use this SGBG in an easy mode.   @ColumnFamilyValue(nome = "person")// public class Person implements Serializable {   private static final long...

From 1995, when was launched the first Java's version, to 2012 the Java evolute obtained seven versions, many improvements and fixes bugs. In 2011 the biggest “boom” in the java world was about the openjdk recently it's grew in exponential way, but there are some myths arount it, for example, some people know the openjdk like “poor brother” of SUN's JDK (actually Oracle...

A preview of the pure Java version of VisualLangLab is available here. The GUI, and other characteristics, remain virtually unchanged (see documentation), but the download is very much smaller as it does not bundle the entire Scala API. The preview does not yet support packrat parsing, and an API for application programs is not yet available. All grammar development and testing features are...

Blogging

This page is for introducing Grizzly-Thrift server/client modules and sharing various benchmarking results. Object serialization/deserialization of Java comes expensive. For improving this lack, we sometimes used to use other frameworks for RPC such as Protobuf and Thrift which support various programming languages, RPC and own data structures. Especilally, Thrift has already provided various...

J2SE

  Was added to his package to facilitate applications which needs scalable processes. A feature is atomic variable. Variable atomic means that it cannot be divided -  it's like the S.O. with any resource (Driver CD, USB) cannot be divided but needs be used in many processes.              ...

GUI

Welcome java 7 part 3 -NIO 2 JSR 203   So like the coin project, in the NIO 2 there aren't unprecedented features in this e -specification, but now it's possible do some easier work I/Os in java. With the class java.io.Files are possible to perform several operations in simple mode. For that it needs and uses the java.io.file.Path, this interface represents files and...
