Episode 334 - Leap seconds break everything
Josh and Kurt talk about leap seconds. Every time there's a leap second, things break. Facebook wants to get rid of them because they break computers, but Google found a clever way to keep leap seconds without breaking anything. Corner cases are hard, security is often just one huge corner case. There are lessons we can learn here.

Episode 333 - Open Source is unfair
Josh and Kurt talk about Microsoft creating a policy of not allowing anyone to charge for open source in their app store. This policy was walked back quickly, but it raises some questions about how fair or unfair open source really is. It's mostly unfair to developers if you look at the big picture.

Episode 332 - PyPI: 2FA or not 2FA, that is the question
Josh and Kurt talk about PyPI mandating two factor authentication for the top 1% of projects. It feels like a simple idea, but it's not when you start to think about it. What problems does 2FA solve? How common are these attacks? What are the second and third order effects of mandating 2FA? This episode should have something for everyone on all sides of this discussion to violently disagree with.

Episode 331 - GPG, but nothing makes sense
Josh and Kurt talk about their very silly GPG key management from the past. This is sadly a very true story that details how both Kurt and Josh protected their GPG keys. Josh's setup is like something out of a very bad spy novel. It was very over the top for a key that really didn't matter.

Episode 330 - The sliding scale of risk: seeing the forest for the trees
Josh and Kurt talk about the challenge of dealing with vulnerabilities at a large scale. We tend to treat every vulnerability equally when they are not equal at all. Some are trees we have to pay very close attention to, and some are part of a larger forest that can't be treated as individual vulnerabilities. We often treat risk as a binary measurement instead of a sliding scale. Show Notes gsd.id The Register OpenSSL story OpenSSL bug
Episode 329 - Signing (What is it good for)
Josh and Kurt talk about what the actual purpose of signing artifacts is. This is one of those spaces where the chain of custody for signing content is a lot more complicated than it sometimes seems to be. Is delivering software over https just as good as using a detached signature? How did we end up here, what do we think the future looks like? This episode will have something for everyone to complain about! Show Notes Twitter thread Kurt's security advisory page Bug 998

Episode 327 - The security of alert fatigue
Josh and Kurt talk about a funny GitHub reply that notified 400,000 people. It's fun to laugh at this, but it's an easy open to discussing alert fatigue and why it's important to be very mindful of our communications. Show Notes GitHub 400K notifications Hacker News thread Reddit user TV Bluetooth
Episode 326 - Big fat containers
Josh and Kurt talk about containers. There are a lot of opinions around what type of containers is best. Back when it all started there were only huge distro sized containers.

Episode 324 - WTF is up with WFH
Josh and Kurt talk about the whole work from home debate. It seems like there are a lot of very silly excuses why working from home is bad.

Episode 321 - Relativistic Security: Project Zero on 0day
Josh and Kurt talk about the Google Project Zero blog post about 0day vulnerabilities in 2021. There were a lot more than ever before, but why?

When the universe around you is expanding but you're staying the same size, you are actually shrinking. Show Notes Google Project Zero blog post Apple 0days Joint cyber advisory
