If you are starting a new project on ASP.NET Core in 2026, the single biggest frontend decision you will make is Angular vs React. Both frameworks pair beautifully with a .NET backend, both have Visual Studio templates, and both are used by Fortune 500 companies to ship serious enterprise applications.

There was no way to predict which one it would be before the session started.That is not how it works anymore. What changedI stopped trying to control the output through the prompt and started defining what the output must look like before the first line is generated.A rule system. Not a prompt template. Not a longer description. A

I Tested Claude Haiku, GPT-4o Mini, and Gemini Flash on Real Tasks. Here's What Actually Happened.Every few weeks someone posts a new model comparison and it's always the same: benchmark scores, carefully designed test prompts, neat bar charts.

I made DuckDuckGo's invisible tracker blocking visible, here is how it looks

How many companies do you think track you when you visit your most-used website?I guessed maybe 5. I was wrong by a lot.That question is what pushed me to build this.DuckDuckGo blocks trackers silently. You never see what you were protected from.

Two headless browsers run in parallel, i.e., one protected with DDG's actual
