Programming: OpenJDK, Python, PyGame and Pandas
-
OpenJDK
OpenJDK is a free, open-source version of the Java Development Kit for the Java Platform, Standard Edition (Java SE). OpenJDK, which stands for Open Java Development Kit, originated from an effort initiated by Sun Microsystems in 2006 and is now sponsored and led by Oracle. The project is licensed under the GNU General Public License (GNU GPL) version 2 with a linking exception. Without the linking exception, components that linked to the Java class library would be subject to the terms of the GPL license.
Since the release of Java SE version 7, OpenJDK has been the official reference implementation. A few notable components that fall under the OpenJDK project include the Java class library, the Java compiler, the Java Runtime Environment (JRE) and the Java virtual machine (JVM). Unlike other JDK release projects, which focused on releasing one feature at a time before terminating, OpenJDK is a long-term, ongoing project. OpenJDK follows a strict, time-based model that is split into development branches and will release new features every six months.

Pandas Tutorial in Python
According to the Pandas homepage: pandas is an open source, BSD-licensed library providing high-performance, easy-to-use data structures and data analysis tools for the Python programming language.
One of the coolest things about Pandas is that it makes reading data from common data formats like CSV, SQL etc. very easy which makes it equally usable in production grade applications or just some demo applications.

Adjust the boy sprite animation
Hello, and welcome back, we are almost done coding the player animation mechanism after we have finished the player boundary detection mechanism in the last article but before we can go to the next stage we need to tidy up the player animation mechanism first by introducing the standstill image of the boy when the boy is not moving and that image will either face left or right or up or down based on the direction of the boy at the time he stops moving. In order to achieve this we only need to edit two files.
The first file we need to edit is the main file where we will include the keyup event so we can set the x different or y different to zero when the boy who is moving in either x or y-direction suddenly stop moving.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
