    ...While gnuplot, created from Gnu, is a tool to create plots and graphs, GnuPlot lacks a GUI to click and plot. Wouldn't it be nice to have GUI for GnuPlot? JAGPI is a GUI for GnuPlot. Referencing to jpg - a GUI for GnuPlot in Java, JAGPI is developed in C# and is more simple to use. Using GnuPlot.exe, you need to learn some codings or programming to create graphs. Using JAGPI, you do not need to learn any codings to create graphs. If you know some GnuPlot, you can use the generated codes, edit and put in GnuPlot.exe.

    Learn Julia the Hard Way

    Learn Julia the hard way

    The Julia base package is pretty big, although at the same time, there are lots of other packages around to expand it with. The result is that on the whole, it is impossible to give a thorough overview of all that Julia can do in just a few brief exercises. Therefore, I had to adopt a little 'bias', or 'slant' if you please, in deciding what to focus on and what to ignore. Julia is a technical computing language, although it does have the capabilities of any general-purpose language and...

    In order to assure software performance, software needs to be tested accordingly as early as possible - only weaknesses diagnosed early can be assessed quickly and cheaply. ContiPerf enables performance testing already in early development phases and in an easy-to-learn manner: A developer writes a performance test in form of a JUnit 4 test case and adds performance test execution settings as well as performance requirements in form of Java annotations. When JUnit is invoked by an IDE, build script or build server, ContiPerf activates, performs the tests and creates an HTML report. The report provides a detailed overview of execution, requirements and measurements, even providing a latency distribution chart. ...
