Are AI chatbots making us lose control of our brains?

This week I’ve been at SXSW London. There’s been music, film, and a lot—and I mean a lot—of talk about AI. I also had the opportunity to sit down with Gloria Mark, a psychologist at the University of California, Irvine, who has spent the last 30 years studying how people interact with digital technologies.

How Excel is Used in Real-World Data Analysis

Introduction Excel is one of the most used tools for data analysis. It allows beginners like myself to easily clean, organize, analyze and visualize data.Excel enables users to work with large datasets and extract meaningful insights without requiring advanced technical skills. What is Excel Excel is a spreadsheet that allows you to collect, organize, analyze, calculate, and visualize data efficiently.Despite the emergence of other data analysis tools like SQL and Power BI, Excel remains one of the most widely used tools for both personal and professional data management.This can be credited to its ease of access, learning, and use.

Qisquiz: A Quiz App for Learning Qiskit v2.X

Qisquiz: A Qiskit v2.X Certification Prep App I built Qisquiz , a web app for learning Qiskit v2.X and preparing for the IBM Certified Quantum Computation using Qiskit v2.X Developer - Associate certification exam. You can try the app here: https://qisquiz.vercel.app/ The GitHub repository is here: https://github.com/dorakingx/qisquiz The concept of Qisquiz is simple: Master Qiskit, one quiz at a time. In other words, Qisquiz is a quiz-based certification prep app that helps learners study Qiskit one question at a time. The target exam is: Exam C1000-179: Fundamentals of Quantum Computing Using Qiskit v2.X Developer Why I Built Qisquiz Qiskit is one of the most important development tools for learning and building quantum computing applications. It is useful for creating quantum circuits, running simulations, using IBM Quantum hardware, and experimenting with quantum algorithms. However, Qiskit v2.X includes several APIs and concepts that learners need to understand carefully. For example, certification prep requires knowledge of topics such as: Qiskit Runtime SamplerV2 EstimatorV2 PUBs, or Primitive Unified Blocs BackendV2 backend.target Transpilation ISA circuits Dynamic circuits OpenQASM 3 Result object handling Little-endian and big-endian interpretation These topics can be learned by reading documentation, but I felt that active practice through quizzes is especially useful for exam preparation. That is why I built Qisquiz , a quiz-based learning app focused on Qiskit v2.X. What Is Qisquiz? Qisquiz is an independent quiz-based learning app for Qiskit v2.X. The current version is organized around the 8 sections of the IBM Qiskit v2.X Developer certification exam. The current question bank includes: 120 original questions 44 code-based questions 40 hard questions 8 sections 15 questions per section Qisquiz is not an official IBM or Qiskit product. It is an independent learning tool that I built to help myself and other learners prepare more effectively. Covered E

Your What Keeps Me Going!

This specific undertaking is not fundamentally burdensome in terms of labor; however, this endeavor serves as the crucial support for my unwavering commitment to see it through to its ultimate conclusion. It is precisely the motivation behind my relentless 72-hour shifts and the impetus that prevents me from ceasing my efforts. My affection amidst my grief—my aspiration is to assist others and ensure that the tragedy you experienced is never repeated. Caitlyn Walmsley, RIP. I will love you always.

Building a Real-Time Chat Feature with Django Channels and React

Building a Real-Time Chat Feature with Django Channels and React Real-time features have become table stakes for modern web applications. Whether it is a customer support widget, a collaborative tool, or a social platform, users expect instant communication without page refreshes. In this article, I will walk through how we built a production-ready real-time chat feature using Django Channels and React at UCDREAMS. Why Django Channels? Django is traditionally synchronous. It handles one request at a time per worker. This works fine for standard HTTP requests, but WebSocket connections require persistent, bidirectional communication. Django Channels extends Django to handle WebSockets, background tasks, and asynchronous protocols alongside traditional HTTP. The beauty of Channels is that it does not replace Django. It layers on top, letting you keep your existing models, ORM, authentication, and admin panel while adding real-time capabilities. For a team already invested in Django, this is a massive advantage over introducing an entirely separate real-time server. Setting Up the Backend Start by installing Django Channels and a channel layer. Redis is the recommended backend for production use: channels == 4.0 . 0 channels - redis == 4.2 . 0 daphne == 4.0 . 0 Configure your Django settings: INSTALLED_APPS = [ ... " channels " , ] ASGI_APPLICATION = " your_project.asgi.application " CHANNEL_LAYERS = { " default " : { " BACKEND " : " channels_redis.core.RedisChannelLayer " , " CONFIG " : { " hosts " : [( " 127.0.0.1 " , 6379 )], }, }, } Building the WebSocket Consumer The consumer handles WebSocket connections: import json from channels.generic.websocket import AsyncWebsocketConsumer class ChatConsumer ( AsyncWebsocketConsumer ): async def connect ( self ): self . room_name = self . scope [ " url_route " ][ " kwargs " ][ " room_name " ] self . room_group_name = f " chat_ { self . room_name } " await self . channel_layer . group_add ( self . room_group_name , self . cha
