Project Management Methodologies in Tech In tech teams, a project management methodology guides how you plan, track progress, and deliver products. It shapes how we gather requirements, choose a cadence, and communicate with stakeholders. There are two broad families: plan-driven methods that lock in the plan early, and iterative methods that welcome change during the project. Waterfall is a classic plan-driven approach. It fits projects with stable requirements or regulated environments. The team completes phases in sequence: requirements, design, build, test, deploy. Changes are costly, so upfront clarity matters. ...

Data Privacy Regulations Worldwide Global privacy rules are no longer optional. Governments in Europe, the Americas, and Asia have passed laws that give people control over their data. For companies, this means mapping who has access to data, explaining why you collect it, and honoring requests to view, move, or delete it. Europe’s GDPR sets a high standard for data rights and accountability. It applies to anyone processing EU residents’ personal data, even if the company is outside the bloc. Key requirements include a lawful basis for processing, transparent notices, data minimization, and strong transfer rules for cross-border data. Fines can be large for violations, and data controllers must keep records and conduct impact assessments for risky processing. ...

Databases in Practice: From Relational to NoSQL Many teams begin with a relational database because the data sits in neat tables and SQL feels familiar. But modern apps often demand scale, flexible schemas, and fast iteration. Relational databases excel at data integrity and powerful queries, while NoSQL systems offer speed and adaptability. The goal of this post is practical: map the options to real problems, not declare a winner. Both approaches can coexist in a well‑designed data strategy. ...

Web Servers in Practice: Performance, Security, and Reliability Web servers stand between users and apps, shaping every online experience. In practice, three goals guide real setups: performance, security, and reliability. Each choice affects the others, so teams tune them together rather than in isolation. Performance in practice Performance starts with the basics: hardware, operating system limits, and the software you choose. For many sites, serving static files is the easiest win. Use a fast server and tune worker or event-based processes to handle concurrent connections. Enable compression, set sensible cache headers, and offload heavy tasks to the backend when possible. Modern protocols like HTTP/2 or HTTP/3 help with multiplexing and latency, while TLS adds some overhead that you can mitigate with session resumption and careful cipher choices. ...

Video Streaming Technology and Delivery Video streaming brings live and on‑demand content to screens around the world. It relies on three simple ideas: encode, deliver, and adapt. When done well, viewers get smooth video even on slower networks. How streaming works A video source is captured and encoded to a digital format. The stream is divided into small chunks and packaged for delivery. A content delivery network (CDN) stores and serves these chunks from many locations. The player on your device requests chunks in sequence, buffers a few seconds, and plays. If the network slows, the system can switch to a lower bitrate to avoid rebuffering. Manifest files, such as playlists, guide the player on which chunks and bitrates to fetch. ...

Communication Protocols You Should Know Protocols are the rules that let devices and programs exchange data. Knowing a few core ones helps you build reliable apps, fix issues faster, and protect information. Common families TCP/IP basics: Data travels as packets. TCP handles reliable delivery, ordering, and error checking. IP routes packets across networks. Together they form the backbone of most online services. HTTP and HTTPS: The most common way apps talk to services uses a simple request/response model. HTTPS adds TLS to keep data private in transit. Status codes tell clients what happened, from success to errors. ...
