Backup S3, Google Drive, iCloud, Notion with Plakar

Bret is joined by the founders of Plakar - Julien Mangeard and Gilles Chehade - to nerd out over backup engineering. The kind where you're building your own file formats and cryptographic layers, not just wiring up cron jobs. We get into how Plakar deduplicates and encrypts at the source so your cloud provider never sees your keys. Also, their snapshot model has no chain dependencies, which means you can delete any backup without breaking the others. We had a fun hour of backup horror stories, ransomware pragmatism, where I'm lobbying hard for a Docker volume integration.

Your Images are Out of Date (probably) - The Silent Rebuilds problem

Container base images (like Official Docker Hub images) are often updated without new tag versions. I call this Silent Rebuilds. There's no way to know this happens without image digest-checking automation like Dependabot and Renovate with specific settings. Failure to keep up-to-date is a prime source of vulnerabilities that can lead to serious security breaches. Automate the updates!

AI Wins and Misses for 2025

I'm joined by Nirmal Mehta of AWS and Viktor Farcic from Upbound, to go through our 2025 year in review. We look into the AI tools that consumed us this year, from CLI agents to terminal emulators, IDEs, AI browsers - what worked, what flopped, what's worth your time and money, and what we think isn't!
