Michal Ganzarcik discusses the importance of maintaining quality standards in iterative development processes. He critiques the common practice of prioritizing quick implementations, often at the expense of thoroughness, by using a metaphor of a cow producing manure. While iterative methods can lead to progress, they can also result in poorly constructed outcomes if quality is neglected. Instead, he advocates for a focus on producing high-quality building blocks in each iteration, akin to constructing a palace. Consistent quality is necessary to create a robust and

Axana is a portable MRI scanner developed by Wellumio, designed to improve stroke diagnosis and treatment. Strokes are a leading cause of death and disability globally, with timely medical imaging being crucial for effective treatment. Strokes can be ischemic (caused by blockages) or hemorrhagic (resulting from bleeding), making accurate diagnosis essential to prevent incorrect treatments. Many medical facilities lack adequate MRI equipment, causing delays that can harm patients during the critical first hour after a stroke, known as

The content discusses Playwright, an automation tool that goes beyond being a mere testing framework. It emphasizes that Playwright executes browser-based actions reliably, utilizing ARIA roles for element locators rather than visual or CSS classes, making it resistant to minor styling changes. However, it warns against using the page.waitForTimeout() function, highlighting it as an antipattern. This function introduces 'hard waits' that are inflexible and can lead to brittle and slow tests. The text argues that these waits create
