I blog about CTFs and system administration. Sometimes a bit of reverse engineering as well.

Running your own mail server, with your own domain, is awesome because you can do stuff like this.
Ever since I deployed this on my server https://l1cafe.blog/2018/06/14/defeat-spammers, I have banned quite a few incoming addresses... And it's been barely a year.

The actual NSA recommends using an ad blocker for your security https://apps.nsa.gov/iaarchive/library/supporting-documents/blocking-unnecessary-advertising-web-content.cfm #infosec #security
And you should be using uBlock Origin. https://github.com/gorhill/uBlock/

Yes, @mozilla makes mistakes (same as the rest of us humans). And yes, their last one was ugly. But, still, they're the only ones in the browser business trying to do the right thing. So I'll keep using Firefox, Focus, Send, and the rest of cool software they produce.

@eloisa I'm currently trying to make a version of that famous black hole image that is more accessible to visually-impaired people. Current prototype:

More generally I'd like to make more of astronomy accessible like this - it's such a cool topic but the presentations are often so visual. Can we do better?
Many thanks for all your boosts, favs, and nice comments!
If you’re into cybersecurity, infosec, privacy, or any related discipline, just drop me a fav and/or a boost, I will definitely follow you.
Feel free to PM me as well, always happy to read from fellow hackers!

rant about firefox
*sighs*
Folks, the thing that happened with Firefox was an accident. It was not part of some sinister plot. If you think it is, it's because you have no idea how complicated providing a browser and all its security features are.
Climb back from that ledge. Next you're going to talk about chemtrails and flat Earth.

Chrome went through the same journey. They got to the point that to subvert it at all, malware started overwriting Chrome with custom-compiled old versions of the Canary developer builds, set to never update, and allow their injected malicious extensions. It's savage out there.
