Tptacek has a software security company, and he is one of the unofficially designated security experts here (with cperciva). He is the #1 in the karma ranking and has even more karma that the site founder (pg)! If he says that “[Willem Pinckaers] knows what he's talking about”, for me it’s very strong reference for Willem Pinckaers.

Also, we generally don’t like oneliners here, try writing a longer comment. Definitively avoid Pls!!!! (And just in case, also try to avoid unoriginal jokes and memes.)

You are quite new here and your last 2 comments were heavily downvoted. I hope that someone upvote them until they are dark gray again. (The second comment, were you tried to explain your intentions, is not a bad comment.) [You’ve just deleted your second comment.]

Alternative redaction:

“I searched for Willem Pinckaers in Google and there is a lot of information about him. Can you recommend a few pages with his main projects to understand his background and credentials. Also, I’d love to know more about the projects in which you worked together in Matasano.”

[Note: perhaps the internal projects are under a NDA/top-secret/paranoid-client, and they can’t be explained until 2050.]

Ok, Thank you for the clarification. The irony is I probably should have been a bit more elaborate in the context of my question. I'm fairly new on Hacker News and I probably should read more comments pertaining to other posts to get a better perspective of the etiquette on here. But again, thanks for the clarification and I will commit to bringing proper thought to my comments
