Spent a good portion of the morning playing with xpra on Ubuntu 18.04. Initially, didn't like it much as Ubuntu's prepackaged binary is crap (lacks the HTML5 portion of the larger code base). After switching to the hosted repos, I was able to get it to execute. However, in the long run, it wasn't what I was seeking.

What was I reading in November 2019

Another busy month. Worked on getting setting up easily deploy-able private architectures for students, using Docker, OVS, and some scripting. Mixed in some Guacamole and a touch of image mapping, and we have our first lab for the firewall class. Also spent the last of the 2018 Christmas money on classes (I'm now backlogged for 15 classes).


- Pwn2Own Tokyo 2019 - Day One Results
- Rage Against the Maschine - a discussion on reverse engineering of a specific piece of hardware
- Isolating the logic of an encrypted protocol with LIEF and kaitai - more reverse engineering
- Feature walk-through for the XAMN v4.4 forensics tool


- OpenAI has published the text-generating AI it said was too dangerous to share - Someone believes their own hype a bit too much, I think...
- Bypassing GitHub s OAuth flow
- One man's junk
- GitRoyalty - WTF?! If you drop opensource behind a paywall, it's not opensource anymore! This is dumb.
- Rethinking the inotify API as an offensive helper


- File Signatures - a must-have!
- CTF Resources - a work-in-progress


- We reduced our Docker images by 60 with no-install-recommends
- 5 Practical Examples of the dd Command in Linux - I revisited this while learning more about using binwalk to extract hidden files from other files.
- Extracting Kerberos Credentials from PCAP


- The Early History of Usenet, Part II: The Technological Setting
- Configuring Ansible
- Don't Blame the Internet for New Slang


- A Clever Way To Find Compiler Bugs


- AlphaStar: Grandmaster level in StarCraft II using multi-agent reinforcement learning
- Destroying x86_64 instruction decoders with differential fuzzing
- whitequark/unfork


- Study: There may be no such thing as objective reality - A bit too much on theory and philosophy. A discussion, where an experiment (e.g., Schrodinger’s Cat) relies too heavily on dependencies and/or limitations on the experiment. Most everyone can tell you if the cat is alive just by listening or picking up the box. Short version: a scientist's version of navel-gazing.

Above was generated by a homegrown bolt-on script for Wallabag, which is a free utility for capturing web content so that it can be read later.
