PSA: after incredible 10y 10m I'm leaving @Cloudflare to try something new. This journey was incredible and probably made me who I am today Thank you so much for this opportunity @eastdakota, @zatlyn and @icqheretic and I will continue to help build a better Internet on the side

Make sure to watch my talk online from #NDCSecurity when it is up. I accidentally stage-dived during my presentation and flipped a table with glasses. So if not for the content, at least for the laughs.

TFW you've managed to fix a stuck key on an outdoor security keypad by fully disconnecting, disassembling, cleaning, reassembling and connecting it. And it still works!

Full disk encryption on Linux scrambles most of the bytes on your partition, including the filesystem metadata. Most because it encrypts everything except for the LUKS header itself, which stores encryption metadata. If you look at the raw disk, you won't see file headers, directory structures, or even what type of filesystem is installed. You just see encrypted noise. This happens because LUKS sits at the block layer. It creates a virtual device (via the device mapper) that sits on top of your physical disk. Write: The kernel sends data to the virtual device -> LUKS encrypts it -> writes encrypted bytes to the physical disk. Read: You read from the virtual device -> LUKS fetches encrypted bytes -> decrypts it on the fly. This architecture provides flexibility. Because the decrypted virtual device looks exactly like a standard hard drive to the kernel, you can format it with anything. You can put ext4, XFS, or something else inside a LUKS container. The filesystem doesn't even know it's being encrypted. It’s a perfect example of the Unix philosophy: do one thing (encryption) and do it well, then pipe it to the next tool.

Alpine Linux images are great until a dependency needs glibc instead of musl. Start with Alpine. Switch to Debian slim when it breaks. The 50MB you save isn't worth the 6 hours debugging why your Python package won't compile. Pragmatism over purity.

The internet has been a mess since I left. Should I go back to my old job and turn it off and on again for everyone?
