@RealmMedia I was a little surprised by the rebrand - Serial Box was such a cool name. But I have to say, I'm loving "Low Life" - the production quality is exceptional on everything I've listened too. This is Black Library-level audio drama good. I love your service.

Hey, I'm working on a new public project called @HackOvert. Check out "Lazy Bloodhound" a blazing fast toy parser to identify PHP command injection vulnerabilities, or whatever else you want. It's based on the Tree-sitter parser generator: https://t.co/YywqEG5Aij Fun stuff!

[John Toterhi @cetfor]

@emmajane1313 Awesome! Thank you for checking them out! If the logistics work out I'll be teaching a course at OSU on RE this year. So I've been working on getting some additional resources up at @HackOvert to help me work on my presentation and delivery.

[John Toterhi @cetfor]

@flakpaket @krispHQ Oh man, that was a close one. Coffee almost came out of my nose. 🤣
