@blubbfiction @hack_lu For @MISPProject: Integration with @tricaud's Sighting DB, new sighting push mechanism thanks to the ideas of @mount_knowledge, local galaxy creation/modification thanks to the discussions with @DennisRand and integrations with both Sigma and Osquery. Thanks all for the ideas.

The @RedHat DNS infra seems down. ns[1-4].redhat.com are unresponsive.
I received spam from @eGInnovations at an address only used for @citrix. Did @citrix sell my contact information?

Mega-spelfout in de @volkskrant, of snap ik de woordspeling niet? volkskrant.nl/vk/nl/2844/Arc…

@onnix @EFF Maybe you should retest all Dutch banks for HSTS now that they all claim to support it in @kassa_vara
@Rabobank had in april naar @jelleeh moeten luisteren, dan was er bij @kassa_vara lof geweest ipv kritiek. x.com/Rabobank/statu…

@hpsecurity Please update the SSL certificate for h20564.www2.hp.com it expired 10 hours ago.
@5ean5ullivan This is really blacklisting and easily defeated but they got the interface right. F-Secure should include something like this.
@5ean5ullivan Remember we were taking about whitelisting in NL? This is a great free tool based on SRP: foolishit.com/vb6-projects/c…

Epic troll, or evidence the U.S. is doomed. (via @i0n1c)
Why recursive Microsoft DNS servers should not be publicly reachable: mountknowledge.nl/2013/03/30/why…
@FSecure Thanks for the suggestion, but the F-Secure blog does not have comments enabled. Nor does Brod publish his Twitter account.
