🤖 AI & Machine Learning

Deutsche Telekom Taps AI to Optimize 5G Network Operations

Deutsche Telekom is leveraging AI to improve the performance and efficiency of its 5G network. The AI system monitors real-time traffic and automatically adjusts bandwidth, ensuring better connectivity.

The initiative aims to lower operational costs and boost user experience. It's part of a broader digital transformation strategy.

When AI Meets Hair Bias: How Algorithms Penalize Black Women’s Hairstyles

A study tested AI image tools (Clarifai, Amazon Rekognition, and Anthropic’s Claude) on Black women’s hairstyles—stylized with braids, Afros, and TWAs—and found they were rated lower in professionalism and intelligence compared to straighter styles.

These same styles didn't affect perception of white women in similar images. Models often failed to recognize the same Black woman across hairstyle variations, posing risks in hiring, security, and identity systems. Researchers emphasize the need for hair bias education, inclusive policies, and human oversight when AI is involved in evaluations.

DeepSeek reverts to Nvidia for R2 model after Huawei AI chip fails

DeepSeek’s plan to train its new AI model, R2, on Huawei’s Ascend chips has failed and forced a retreat to Nvidia while delaying launch.

For months, the narrative pushed by Beijing has been one of unstoppable technological progress and a march towards self-sufficiency. However, reality has a habit of biting back. The recent troubles of Chinese AI darling DeepSeek is a textbook example of where ambition meets the hard wall of technical limitations.

After the successful launch of its R1 model in January, DeepSeek found itself under pressure from China to champion the national cause. According to three people speaking to the Financial Times, the message was clear: use Huawei’s chips, not Nvidia’s.

Build UI for your AI Agent! Google Agent Development Kit for Beginners

Have you built a powerful AI Agent with Google's Agent Development Kit (ADK) and deployed it to Vertex AI, but now you're wondering how to actually use it or share it? In this tutorial, we solve that problem!

I'll show you how to use an incredible open-source project, ADK-Nexus, to create a beautiful and functional Streamlit chatbot interface for your deployed Google ADK agents in just a few minutes. This is the perfect way to test your agent in a real-world chat scenario and even share it with your team or end-users.

🚀 Angular

Cross-Repo Conformance with Nx Polygraph

While tech giants like Google and Facebook rely on monorepos, the reality for many companies is different: Business software is often developed in multiple project- or product-related repos. The relatively new Nx Polygraph takes this into account by visualizing dependencies between repos and enforcing common policies.

In this article, you’ll get an overview of Polygraph and show how to develop a conformance rule that ensures the use of a specific Angular version across all repos. This check is especially essential for Micro Frontend projects, where you want to limit yourself to a single version for simplicity.

AngularDart: The Forgotten Sibling of Flutter

Did you know Dart had its own web framework long before Flutter came onto the scene? While Flutter gets all the spotlight today, its lesser-known sibling AngularDart was once Dart’s flagship solution for building scalable web apps.

AngularDart is a structured web framework for building single-page web applications using the Dart programming language. It is a Dart port of Angular (TypeScript)—developed and maintained by Google.

Angular + Jest: All the Unit Test Cases You'll Ever Need

Unit testing isn't just about “getting 100% code coverage.” It’s about writing meaningful tests that simulate real-world use cases, and Jest, paired with Angular, is a powerful combo to do exactly that.

In this guide, we're not just going to tell you what to test. We’ll show you how to test every critical scenario in Angular using Jest with hands-on demo code, best practices, and a professional yet easygoing tone to keep you engaged.

🌐 Web & Frontend

Load Data in Angular Using Route Resolvers Instead of "ngOnInit"

When building Angular applications, a common pattern for fetching data is calling an API inside the ngOnInit lifecycle hook of a component. While this works, it can lead to empty UIs that suddenly “pop” with data once the request completes. This can hurt UX and SEO.

A better approach is to load the data before the component is activated, using Angular’s Route Resolver. This ensures the component receives all necessary data immediately upon rendering.

Model Context Protocol (MCP) for GitHub Copilot in Xcode is Now Generally Available

Model Context Protocol (MCP) support with GitHub Copilot is now generally available for Xcode! Developers can now enable GitHub Copilot with MCP in Xcode to enhance coding intelligence and context awareness.

With MCP support in Xcode, developers can now connect Copilot to both local and remote MCP servers that follow the MCP specification in your IDE. Once configured, Agent Mode can leverage tools exposed by these servers to assist with broader tasks. For example, you can configure a remote GitHub MCP server using a PAT or OAuth to authenticate. Enable actions like creating issues, checking repo history, and searching GitHub.

Mastering Web Cache Deception Vulnerabilities: An Advanced Bug Hunter’s Guide

Web cache deception is a high-impact vulnerability where attackers trick caching mechanisms into storing and serving sensitive content, enabling unauthorized data access or account takeover.
