R-package - a software environment for statistical computing and graphics written in C. Script oriented. Pros: widely used, simple, extensive documentation. Cons: less powerful graphics compared to other programs, no multi-threading, scripting is less powerful compare t widely-used scripting languages.

Java can be rather fast! According to the article posted in ArXiv (http://arxiv.org/abs/1311.1229), Java is faster than C++ in reading data (to be exact, data in the ProMC format, which is based on Google's Protocol Buffers). See Table I of this article.

We often hear the term "big data" (see "Big data" wikipedia link). Taking the path of finding cool words for description of something quite trivial (before we had "not quite big data", and in 10 years from now we will have "monstrously big data"?), how about a new term "small data"? The definition of "small data" is less ambiguous than for "big data": Data that has small enough size for human comprehension.

jPort is finally out (and it is already release 1.4!). What is special about jPort project? jPort is a portable application launcher for Java-enabled platforms (Windows, Linux, Mac). It can launch dozens of free Java-powered programs for office, science, education, code development, entertainment and graphics. If you need a tool to organize all your applications in one place, a single menu (for example, on menuless Windows8) - this is the way to go.

SCaVis is a successor of jHepWork. Why this change in its name? jHepWork has its origin in high-energy physics (remember, Higgs?). The "Hep" part of jHepWork abbreviates "High-Energy Physics". jHepWork is used in several HEP areas, but it is not very popular in this field since high-energy physics is almost completely based on the ROOT C++ package developed at CERN. The reason is that experimental data are written and stored in the ROOT format.

There was recent discussion about Java7 performance for numerical calculations. Few people saw some 20-40% improvement for java7, compare to Java6. This simple script which can be executed in jhepwork shows no such improvement. Run this code above (here I'm using 2 cores) and see it yourself:

According to the forum http://jwork.org/jhepwork/forum/viewtopic.php?id=13 just released Java7 has a bug on Linux platform. It seems like execution of the code for jhplot canvases compiled using jdk6 fails. This bug is perfectly reproducible on the Linux (Ubuntu, Fedora) and related to the graphics package org.freehep.graphics2d.VectorGraphics. Interestingly enough, Jdk7 on windows is fine. This bug was sent to the java7 developers, but they could not reproduce it.
