  • Becoming Better Digital Citizens Through Open Source

    The WordPress Project is on a mission to democratize publishing. As WordPress empowers more people to participate in the digital space, we have the opportunity to make sure that everyone can participate safely and responsibly. Today marks the start of Digital Citizenship Week. We are going to share how open source can be used as a tool for learners (regardless of age) to practice and model the essential parts of being a good digital citizen. [...] Digital Citizenship is for all age groups. Anyone who uses the internet on a computer, mobile device or a TV is a digital citizen. You don’t have to be tech-savvy already, maybe you are taking your first steps with technology. Digital Citizenship Week is a chance to reflect together on our impact on the digital world. It can help us to make our consumption more considered and our interaction friendlier. It enables us to make a positive difference to those around us. All of us can strive (or learn) to become better digital citizens. It can be affected by the access those teaching have had to digital skills and good practice. Adult education classes and community tech hubs play a part in basic tech skill development. Unfortunately, these are not always accessible to those in less populated geographic locations.  Open source communities like WordPress already make a difference in encouraging the principles of digital citizenship, from sharing tech skills to improving security knowledge. They give people an opportunity to learn alongside their peers and many of the resources are available regardless of location, resources, or skills.

  • MongoDB vs. MySQL: How to choose

    During the dot-com bubble in the 1990s, one common software stack for web applications was LAMP, which originally stood for Linux (OS), Apache (web server), MySQL (relational database), and PHP (server programming language). MySQL was the preferred database mostly because it was free open source and had good read performance, which fit well with “Web 2.0” apps that dynamically generated sites from the database. Later the MEAN stack, which stood for MongoDB (document database), Express (web server), AngularJS (front-end framework), and Node.js (back-end JavaScript runtime), came to prominence. The MEAN stack was attractive, among other reasons, because the only language you needed to know was JavaScript. It also needed less RAM than an equivalent LAMP stack.

Security: XML External Entity (XXE) Example and the Latest Patches

  • XML External Entity (XXE) Example

    According to OWASP, an XML External Entity attack is a type of attack against an application that parses XML input. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, denial of service, server side request forgery, port scanning from the perspective of the machine where the parser is located, and other system impacts. If a parser accepts unsanitized XML, we can take advantage of that and send our own crafted external XML payload to exploit our target. This post won’t be long so let’s get into it.
