Production Error EXPOSED: Internal Variables Leaked Public (Software Developers React)

We caught a massive production error during the new Steam Machine launch that exposed internal database IDs and undefined variables to the public. In this episode, we break down exactly what went wrong, how a simple try/catch or React Error Boundary could have saved them, and why "testing in production" is terrifying when millions of dollars are on the line.

Plus, we answer a listener's question about getting stuck on "perfecting" projects. Danny explains why building a "Discord Clone" might actually be hurting your resume and why you need to stop obsessing over your navbar and just SHIP.
