Python versus R for machine learning and data analysis
Machine learning and data analysis are two areas where open source has become almost the de facto license for innovative new tools. Both the Python and R languages have developed robust ecosystems of open source tools and libraries that help data scientists of any skill level more easily perform analytical work.
The distinction between machine learning and data analysis is a bit fluid, but the main idea is that machine learning prioritizes predictive accuracy over model interpretability, while data analysis emphasizes interpretability and statistical inference. Python, being more concerned with predictive accuracy, has developed a positive reputation in machine learning. R, as a language for statistical inference, has made its name in data analysis.

Geode: The Latest Apache Big Data Project to Graduate to Top-Level Status
In recent months, we've steadily taken note of the many projects that the Apache Software Foundation has been elevating to Top-Level Status. The organization incubates more than 350 open source projects and initiatives, and has squarely turned its focus to Big Data and developer-focused tools in recent times. As Apache moves Big Data projects to Top-Level Status, they gain valuable community support. Only days ago, the foundation announced that Apache Kudu had graduated as a Top-Level project.

Open Source Week at SitePoint
At SitePoint, we are proud supporters of Open Source. Regular SitePoint readers may have noticed that! Open is in the DNA of many topics we cover by design; GitHub alone is evidence enough, as it’s pretty much a standard tool for most developers nowadays.

Education management with Moodle: The beginning, middle, and today
Moodle is the de facto standard in open source learning management systems. It is described as "a learning platform designed to provide educators, administrators and learners with a single robust, secure and integrated system to create personalised learning environments." Plus, Moodle is free software, licensed under the GPL.
Martin Dougiamas, Moodle's founder and lead developer, generously took time from his busy schedule to have a good, long talk with me about why he created it, where it is today, and what's next in open education.

Hackathons and bite-sized procurement requests
Public administrations that want to work with open source communities should organise hackathons and other meetings on software development. They should also publish calls for tender that can be answered by individuals and small businesses. These are some preliminary recommendations from the OSOR workshop at the Paris Open Source Summit last Wednesday.

Last batch of ColorHugALS
I’ve got 9 more ColorHugALS devices in stock and then when they are sold they will be no more for sale. With all the supplier costs going recently up my “sell at cost price” has turned into “make a small loss on each one” which isn’t sustainable. It’s all OpenHardware, both hardware design and the firmware itself so if someone wanted to start building them for sale they would be doing it with my blessing. Of course, I’m happy to continue supporting the existing sold devices into the distant future.

Programmers are having a huge discussion about the unethical and illegal things they’ve been asked to do
Earlier this week, a post written by programmer and teacher Bill Sourour went viral. It's called "Code I’m Still Ashamed Of."
In it he recounts a horrible story of being a young programmer who landed a job building a website for a pharmaceutical company. The whole post is worth a read, but the upshot is he was duped into helping the company skirt drug advertising laws in order to persuade young women to take a particular drug.
He later found out the drug was known to worsen depression and at least one young woman committed suicide while taking it. He found out his sister was taking the drug and warned her off it.

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. |
