Criticism of separating teams into "feature" and "customer support" crews. Arguments that this breaks feedback loops, creates resentment, and leads to poorer quality. Rotation between crews suggested as partial solution.
4Mark Klein, AT&T whistleblower who revealed NSA mass spying, has died
- Mark Klein, a former AT&T technician, bravely exposed NSA's mass surveillance program by revealing the existence of Room 641A in AT&T's San Francisco office, where data was secretly copied and monitored. His evidence led to lawsuits against NSA and sparked public demands for surveillance reform, though complete victory remains elusive. Klein's legacy continues through ongoing privacy rights advocacy.

6What makes code hard to read: Visual patterns of complexity (2023)
- The article discusses code readability and visual patterns that impact code comprehension. It explores various metrics for measuring code readability, focusing on Halstead Complexity Metrics from the 1970s and the more recent Cognitive Complexity measure. The author identifies key patterns and practices that make code easier to read and maintain across different programming languages.
Functional vs imperative style
Debate over readability of functional programming constructs like map/filter/reduce chains versus imperative approaches. Most argue functional style is more readable once familiar, while others prefer breaking chains into variables.Code readability measurement
Discussion of whether code readability can be quantified objectively, or if it's inherently subjective and dependent on programmer experience, familiarity with paradigms, and team consensus.Visual patterns in code
Debate about visual formatting like vertical alignment, spacing, and line breaks. Some prefer aligned code for readability while others argue against it due to diff noise and team consistency issues.
7Peer-to-peer file transfers in the browser
- FilePizza is a browser-based file sharing service that enables direct peer-to-peer file transfers using WebRTC technology.
