What I've Learned After Building Websites for Local Businesses as a Web Designer

SimpleLogin vs anon.li - a developer's honest comparison

If you care about your inbox - and your privacy - email aliasing is one of the best habits you can build. The idea is simple: instead of handing out your real address, you hand out a disposable alias that forwards mail to you. One service gets compromised? Disable the alias, never touch your real inbox. SimpleLogin is the established name in this space, now owned by Proton. anon.li is a new priva...

Microsoft Agent Framework: From Zero to Multi-Agent Pipeline

I have some background with other agent frameworks like CrewAI and LangGraph, so when Microsoft released the Agent Framework, a lightweight Python package for building AI agents with native MCP (Model Context Protocol) support, I was curious to give it a try. I decided to build something practical: a pipeline that reads a product backlog from a Markdown file and automatically creates Epics and Sto...

We Ran 7,600+ Cloud Provisioning Tests Across AWS, Azure, and GCP — Here's What We Found

Nobody publishes this data. We measured it ourselves. Cloud providers publish uptime SLAs. They publish pricing calculators. They publish feature comparison tables. None of them publish how long it actually takes to provision infrastructure — or how often it fails. So we built ProvisioningIQ to measure it continuously. Here's what 7,600+ real provisioning tests across AWS, Azure, and ...

Working with AI review is very important

I started working with AI recently, and I have to say that it is a very powerful tool. It can help you with a lot of things, from writing code to generating content. However, how can you be sure that the content generated by AI is accurate and relevant? And when we add automation to our AI workflow, where AI can automatically write a full feature, here is where the review process becomes crucial. ...
