Elon banned me from Twitter for doing journalism. Good riddance.

Posted May 4, 2023 in twitter-threads

It's been nearly six months since Elon Musk threw one of his first tantrums as the King of Twitter and banned me (along with a bunch of other journalists) for tweeting about him censoring Mastodon. A few days later he "reinstated" my account but I was still locked out until I agreed to delete my forbidden tweet that the billionaire didn't like. And I've been locked out ever since.

Capturing the Flag with GPT-4

Posted April 23, 2023 in ai ctf

This weekend I went to BSides SF 2023 and had a blast. I went to some really interesting talks (including an excellent one about adversarial machine learning), but mostly I spent my time solving CTF hacking challenges. And this time, I did it with the help of GPT-4, the latest generation of OpenAI's ChatGPT generative language model. GPT-4 straight up solved some challenges for me, which blew my mind. There were definitely several flags I got that I wouldn't have gotten without the help of GPT-4. For challenges that GPT-4 didn't solve on its own, it provided incredibly helpful tips, or quickly wrote scripts that would have been tedious or time consuming for me to write myself. Good thing there's (almost) no such thing as cheating in CTF!

Stories about Peter Eckersley

Posted September 4, 2022

My friend Peter Eckersley tragically and unexpectedly died on Friday. I hadn't spent much time with him in the last few years, but I wish that I had because he had such a big impact on my life. Wikipedians have created an article about Peter, and Seth Schoen, who worked closely with me and Peter at EFF on the tech team, wrote a memorial for him on the Let's Encrypt forum. I thought I would share a few stories about Peter here.

Qube Apps: a Flatpak-based app store for each qube

Posted November 1, 2021 in qubes code

I really like Qubes but I haven't been using it a lot lately. I have a Qubes laptop that I use for specific high security tasks, but my daily driver the last few months has been Ubuntu or Pop!_OS (I really like the tiling windows and the design), and sometimes macOS. Qubes is great, but it can be cumbersome to use.
