Patching Problems with Persnickety Proxies Purveyed by Paternalistic Princes
A recent Ars Technica article outlined a backdoor in the Go Module Mirror. Even though it's framed as a backdoor, and potentially a vulnerability, it's actually an exploit of a design choice designers of the module mirror made. Kris is joined by Matthew, Dylan, and guest host Jamie Tanna, to discuss this vulnerability-but-actually-feature, the implications for the Go community, and the wider reasons why something like this happened. We go on a journey through the history of modules, the Go community, and a whole lot more. We know this is a long one but we're sure you'll love it! Have thoughts? Reach out to us on social media and let us hear them!
