Buying Google ads for your competitor’s name is already rather sad. Perhaps one day your own product will be interesting enough to advertise. Bless your heart, @semgrep.com

This week I am speaking at @javazone.bsky.social about prompt injection. As developers we need to know how it works and how to defend ourselves to this new type of attack.

Someone really dislikes security, or at least my security talk. But getting a 1-star review 28 min before the talks start is kinda harsh, don't you think 🤔🤯? I hope this person knows there are at least 20 other great talks at @devoxx.fr

Team squirrel 🐿️ on stage! What happens if you put @piotrprz.bsky.social and @maritvandijk.bsky.social on stage teaching about modern Java at @devoxx.fr ? A crossover between a comedy show and a legit experiment.

Heading to Atlanta for @devnexus.bsky.social 2026! I’ll be presenting "The Hidden Security Hazards in Your Java Stack." We're uncovering the vulnerabilities that standard tools often overlook. 🔗 devnexus.org/speakers/bri... #Devnexus #Java #AppSec #Snyk

Today was day one at @jfokus.se. I led a deep-dive session titled “Understanding Prompt Injection: Techniques, Challenges, and Advanced Escalation” in front of a fully packed room. I'm thrilled that so many people showed interest in this important topic of AI security. Thank you all for joining!

I love how you can use JBang to make MCP servers easy available to everyone. Add jbang javaconfmcp@bmvermeer/javaconfmcp to your AI assistent to ask about upcomming Java events or closing CFP's

My talk “Understanding Prompt Injection” briefly had the top spot at @devoxx.com, very briefly. Nevertheless very happy with turnout in the room and the final score. If you joined, thank you so much.
