DocuBurst: Visualizing Document Content using Language Structure

Christopher Collins, Sheelagh Carpendale, and Gerald Penn

Abstract
DocuBurst is the first visualization of document content which takes advantage of the human-created structure in lexical databases. We use an accepted design paradigm to generate visualizations which improve the usability and utility of WordNet as the backbone for document content visualization. A radial, space-filling layout of hyponymy (IS-A relation) is presented with interactive techniques of zoom, filter, and details-on-demand for the task of document visualization. The techniques can be generalized to multiple documents.

Processing is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool. Processing is developed by artists and designers as an alternative to proprietary software tools in the same domain.

Processing is free to download and available for GNU/Linux, Mac OS X, and Windows. Please help to release the next version!

Processing is an open project initiated by Ben Fry and Casey Reas. It evolved from ideas explored in the Aesthetics and Computation Group at the MIT Media Lab.

Postgresql - Counting Sundays

http://www.depesz.com/index.php/2007/12/27/how-many-1sts-of-any-month-were-sundays-since-1901-01-01/

how many 1sts of any month were sundays - since 1901-01-01?

nixternal wrote about boost library for c++.

with it he was able to find the answer to title question in miliseconds (he didn't specify how many, but let's assume that is was less than 10 ms).

so i decided to check how fast can i do it in postgresql …


Pivot queries or CrossTab Queries in PostgreSQL using tablefunc contrib

http://www.postgresonline.com/journal/index.php?/archives/14-CrossTab-Queries-in-PostgreSQL-using-tablefunc-contrib.html


The generic way of doing cross tabs (sometimes called PIVOT queries) in an ANSI-SQL database such as PostgreSQL is to use CASE statements which we have documented in the article What is a crosstab query and how do you create one using a relational database?.

In this particular issue, we will introduce creating crosstab queries using PostgreSQL tablefunc contrib.

Boost library - counting Sundays

http://blog.nixternal.com/2007.12.26/boost-library-rocks/

Boost library rocks!

26 12 2007

I have been messing with a project through the university and we decided that we would go with the Boost library for the project, so to read up on Boost and how to use it, I decided I would attack Project Euler using Boost. One area that Boost really showed its strength was determining how many Sundays fell on the first day of the month between January 1, 1901 and December 31, 2000. In just a few lines, the answer was apparent. Here is the lines of code that answers this problem, and answers it immediately. I had used other calendar solutions in C++ in the past, but the gregorian.hpp library is fast.

#include <iostream>
#include "boost/date_time/gregorian/gregorian.hpp"
 
int main(void)
{
using namespace boost::gregorian;
int count = 0;
date_period dp(date(1901 , Jan, 1), date(2000, Dec, 31));
day_iterator iter(dp.begin ());
 
while (iter != dp. end())
{
if (iter->day() == 1 && iter->day_of_week ().as_enum == 0 )
count++;
++iter;
}
 
std::cout << count << std:: endl;
return 0;
}

The answer takes milliseconds, it is just that fast. Right now I would like to replace my gmpxx libraries for big numbers with a boost library and I think all of my Euler answers will be "boosted."

Planet postgresql, Mylyn, Maven,

http://www.planetpostgresql.org/

http://www.eclipse.org/mylyn/
Mylyn is the Task-Focused UI for Eclipse that reduces information overload and makes multi-tasking easy. It does this by making tasks a first class part of Eclipse, and integrating rich and offline editing for repositories such as Bugzilla, Trac, and JIRA. Once your tasks are integrated, Mylyn monitors your work activity to identify information relevant to the task-at-hand, and uses this task context to focus the Eclipse UI on the interesting information, hide the uninteresting, and automatically find what's related. This puts the information you need to get work done at your fingertips and improves productivity by reducing searching, scrolling, and navigation. By making task context explicit Mylyn also facilitates multitasking, planning, reusing past efforts, and sharing expertise.
