Python 3.15.2 Security Fix, PHP 8.6 Session Defaults, Java 21 in the Browser: Developer News for November 2026

Submitted by jaypabs on
The first week of November 2026 is a busy one for anyone who writes Python, PHP or Java. Python 3.15 is out and already has two security releases, a certificate authority mistake forced the whole Python packaging ecosystem to ship fixes, PHP 8.6 is two weeks away from release with safer session settings, and Java 21 now runs (and even compiles) inside a browser tab. There are also useful updates

Python CSV Tutorial: Read, Write, Append and Filter CSV Files with the csv Module

Submitted by jaypabs on

CSV (comma-separated values) files are everywhere: exported Excel sheets, Google Forms responses, bank statements, grade sheets, product lists for an inventory system. Sooner or later every programmer has to read one, clean it, compute something and write a new file. In Python you do not need to install anything for that. The built-in csv module handles it, including the tricky parts like commas inside a field, quotes, different delimiters and Excel-friendly encodings.

Python Decorators Explained with Examples: Logging, Timing, Retry, Access Control and Caching

Submitted by jaypabs on

Have you ever seen a line like @app.route("/") in Flask or @login_required in Django and wondered what that little @ symbol actually does? That is a decorator, one of Python's most powerful features. A decorator lets you add extra behavior to a function, such as logging, timing, retrying or permission checks, without changing the function's own code.

How to Find Vulnerable Dependencies with npm audit, pip-audit and composer audit

Submitted by jaypabs on
Most of the code in a modern project is not code you wrote. A small PHP app pulls in a dozen Composer packages, a React front end can install hundreds of npm packages, and even a simple Python script often depends on libraries that depend on other libraries. Every one of those packages can contain a known security vulnerability, and attackers actively look for sites running old, vulnerable

Library Management System using Python Flask and SQLite with Source Code
The Library Management System is a web application built with Python Flask and SQLite. It lets a librarian manage books and members, issue and return books, and instantly see which loans are overdue, all from a clean browser-based dashboard. It is small enough to read in one sitting, yet it covers the features teachers usually look for in a school project: login, full CRUD, searching

How to Review AI-Generated Code Before You Merge: A Practical Checklist

Submitted by jaypabs on
AI coding assistants can now write whole functions, open pull requests, and even fix their own failing tests. That is a real productivity boost, but it also changes your job. You write less of the code yourself, so more of your value comes from reading it carefully before it reaches your users. Code that looks clean and passes a quick glance can still hide bugs, security holes, and design choices
