OpenSource

Streaming Data Platforms: Kafka, Pulsar, and Beyond Streaming data platforms help teams publish and consume a steady flow of events. The two most popular open-source options are Apache Kafka and Apache Pulsar. Both store streams and support real-time processing, but they approach the problem with different design goals. Kafka focuses on a durable log with broad ecosystem support, while Pulsar separates storage and compute, offering strong multi-tenant capabilities and built-in geo-replication. ...

Understanding the Landscape of Big Data Tools Big data projects rely on a mix of tools that store, move, and analyze very large datasets. Hadoop and Spark are common pillars, but the field has grown with streaming engines and fast query tools. This variety can feel overwhelming, yet it helps teams tailor a solution to their data and goals. Hadoop provides scalable storage with HDFS and batch processing with MapReduce. YARN handles resource management across a cluster. Many teams keep Hadoop for long-term storage and offline jobs, while adding newer engines for real-time tasks. It is common to run Hadoop storage alongside Spark compute in a modern data lake. ...

Secure Software Supply Chains: Guarding Dependencies Today, many apps rely on libraries and tools we do not own. A single compromised package can harm an entire system. To protect users, teams should treat dependencies as a security concern, not a later task. A clear strategy helps: know what you depend on, verify what you receive, and respond quickly when problems arise. Supply chains can fail at several points: a library in a registry, a compromised maintainer, a wrong build configuration, or a vulnerable transitive dependency that slips through. The risk grows with many connected components and automated pipelines. Simple checks are not enough; you need visibility across the whole chain. ...

Big Data Tools Simplified: Hadoop, Spark, and Beyond Big data work can feel overwhelming at first, but the core ideas are simple. This guide explains the main tools, using plain language and practical examples. Hadoop helps you store and process large files across many machines. HDFS stores data with redundancy, so a machine failure does not lose information. Batch jobs divide data into smaller tasks and run them in parallel, which speeds up analysis. MapReduce is the classic model, but many teams now use higher-level tools that sit on top of Hadoop to make life easier. ...

The Future of Computer Science: Trends to Watch Computer science is evolving beyond one field. Artificial intelligence is no longer optional; it sits at the core of many products. From software assistants that draft code to systems that tune themselves, AI helps developers move faster. New hardware, especially AI-focused chips, makes models run with less energy and latency. This shift changes how teams work, empowering automation while demanding careful design. ...

Content Management Systems in the Digital Era Content management systems (CMS) help teams publish, organize, and update online content without heavy coding. In the digital era, a good CMS saves time, supports collaboration, and keeps websites secure. The right choice fits the needs of the content team and the site’s goals, whether it is a small blog, a product catalog, or a corporate portal. Types of CMS CMSs come in several flavors. Traditional CMSs like WordPress or Drupal provide templates and a live front end. They are easy to start, offer many plugins, and suit many small to mid-sized sites. Headless CMSs store content and expose it via APIs, so the front end can be built with any technology, from React to mobile apps. Decoupled CMSs separate back end and front end but offer more control and predictable updates across channels. ...

Big Data Tools: Hadoop, Spark, and Beyond Big data tools come in many shapes. Hadoop started the era of distributed storage and batch processing. It uses HDFS to store large files across machines and MapReduce to run tasks in parallel. Over time, Spark offered faster processing by keeping data in memory and providing friendly APIs for Java, Python, and Scala. Together, these tools let teams scale data work from a few gigabytes to petabytes, while still being affordable for many organizations. ...

Content Management Systems for Diverse Audiences Web sites serve many users: readers, authors, translators, and administrators. A CMS should feel usable by all, not only by tech-savvy editors. This guide explains what to look for in a system that supports accessibility, multilingual content, and easy collaboration. It also offers practical steps for teams at any size. Why diversity matters in CMS design Diversity goes beyond language. It includes different devices, reading levels, and ways people interact with the web. When a CMS supports inclusive publishing, a site becomes clearer, faster, and more trustworthy. Teams save time, and users experience fewer barriers. ...

Content Management Systems: Choosing the Right Tool A content management system (CMS) helps teams publish, organize, and reuse content across pages and channels. The right CMS fits your goals, your skill set, and your hosting plan. Start by asking who will publish, what content types you need, and how you will measure success. Clear goals prevent feature bloat and keep maintenance affordable. There are three broad CMS categories to consider: ...

Content Management Systems in the Real World Content management systems, or CMS, help teams create, organize, and publish content. They sit between writers and visitors, making it easier to update pages, manage media, and control who can edit what. In practice, a CMS is not just a software choice; it shapes workflows, roles, and risk. In the real world, teams weigh content needs, technical skills, and budget. A small site with a single editor may use WordPress or Ghost for simplicity. A larger nonprofit might need roles, multilingual content, and security reviews, so Drupal or a headless setup can be better. Modern teams often use a headless CMS for content storage and an independent frontend, allowing faster updates and better developer experience. ...
