The Key Points of Working Effectively with Legacy Code

Struggling with Legacy Code and not enough time to clean it up? can help you rescue any codebase quickly and safely ! “Legacy Code is code without tests” If you’ve come across that definition, it’s from Michael Feathers’ book: Working Effectively with Legacy Code. While I have a slightly extended definition, this is a very valid and useful one! Feathers’ book is from 2004. Yet, its content doesn’t get outdated.

The story of how RSS beat Microsoft

People like to tell the story of how VHS beat Betamax because adult film studios backed VHS. It’s a clutch-your-pearls story that says nothing about why these multi-million-dollar businesses picked one format over the other. The real story is that while Betamax tapes had better resolution and fidelity, VHS was cheaper, offered longer recordings, and, most importantly, was the more open format.

Amazon Music launches AI-powered weekly playlists based on 'preferences and mood'

engadget.com Unknown 2025-10-11 15:42:39

Amazon Music has just launched new AI-powered weekly playlists based on the "preferences and mood" of listeners. This just means it scrapes what you've already been listening to and extrapolates further. It doesn't apply modern technology to gauge the actual mood of users. The company says the playlists include "a curated mix of familiar favorites from their most listened-to artists and latest favorites to new discoveries."

Meta allegedly suppressed research that suggested kids were exposed to certain dangers when using its VR headsets, according to a report by The Washington Post . Current and former employees have presented documents to Congress that describe incidents in which children were groomed by adult predators in VR, but allege that internal reports were edited to omit the worst of these offenses.

Job Mismatch and Early Career Success

How does being over- or underqualified at the beginning of a worker's career affect skill acquisition, retention, and promotion? Despite the importance of mismatch for the labor market, self-selection into jobs has made estimating these effects difficult. We overcome endogeneity concerns in the context of the US Air Force, which allocates new enlistees to over 130 different jobs based, in part, on test scores.

Using Claude Code SDK to reduce E2E test time

End-to-end (E2E) tests sit at the top of the test pyramid because they're slow, fragile, and expensive. But they're also the only tests that completely verify complete user workflows actually work across systems. Due to time constraints, most teams run E2E nightly to avoid CI bottlenecks. However, this means bugs can slip through to production and be harder to fix because there are so many changes to isolate the root cause.
