LinkedIn Releases Pinot: An Open Source, Real-Time, Business Analytics Platform
Pinot has been the de-facto analytics program used by LinkedIn for more than two years to provide insight to information like profile views, company follow analytics and A/B testing analytics. The program provides an OLAP datastore that emphasizes scalability, low latency, data freshness, and high availability. It uses data from Hadoop and Kafka, and provides an SQL-like query language that includes functionality such as: filtering, aggregation, group by, order by, and distinct entries. The source code can be acquired on GitHub, and the project wiki has detailed information about why and how you might want to use this software.
Wayland Gets a License Fix
A problem with Wayland’s license was recently uncovered when a Wikipedia editor pointed out a discrepancy between the license statement in the project’s FAQ, and the license found in the actual code. The code was licensed under a Historical Permission Notice and Disclaimer (HPND) license when it should have been licensed under MIT. This confusion arose out of the project’s initial plan to retain full compatibility with the X11 window manager license, but the license text was copied from an older version of X11. Our own Bryce Harrington submitted the patch to apply the correct license to the code and address this problem, and it appears there will be little to no problem implementing the new license.
GIMP Gets its First Processing Engine Update in 3 Years
GEGL is the image processing engine that forms the foundation for many of GIMP’s functions. Version 0.3 was recently released, and is the first update the engine has seen in three years. It includes experimental multi-threading support, mipmaps, a new default tile backend, and 71 new image processing operations which are mostly ports of existing GIMP filters that allow non-destructive editing workflows. This engine is not yet available for the average user to download and use, but the community hopes to make its updates a part of GIMP starting with version 2.10.
Linux Foundation Releases Essentials of Linux Systems Administration Course on EdX
The need for Linux Systems Administrators is growing, a trend highlighted by a recent Linux Foundation (LF) Survey. Proper education and training is needed in order to prepare individuals for a career in Linux, and the LF is helping that happen with the release of LFS201: Essentials of Linux System Administration on the popular online education platform EdX. It expands on LFS101: Introduction to Linux, which can be audited for free. The cost of the course is $399 and it includes all of the knowledge needed to prepare for the Linux Foundation Certified Systems Administration Exam.Image Credits: Open Source Way
