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.

Earlier this month at @jcon.one, I discussed Agentic security with Baruch Sadogursky from @tessl.io. It is a crucial yet often overlooked topic among developers. Both Snyk and Tessl can assist, but the key point is recognizing the issue and acting on it now. www.youtube.com/watch?v=xCre...

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.
