OpenCode with https://t.co/OBONWhb05y and Qwen3.8 Flash is remarkable.

I am excited to share that our paper "DRMD: Deep Reinforcement Learning for Malware Detection under Concept Drift" has been accepted to AAAI 2026.

the CIA is not ready for the RL era

israeli intelligence guy just hacked into a live surveillance camera in front of me with an exploit generated by qwen

vulnerable software is simulatable.
penetration success is verifiable.
hacking is RLable.

@ImLunaHey Stop running things on my laptop 😡

Many cyber simulators have been built for training autonomous blue agents. If your environment setup is: (obs, reward) → red turn → blue turn → (obs_2, reward_2), then it's like trying to play chess with a bag placed over your head before each of your opponent's moves.

I spent my weekend thinking about whether Freud’s tripartite personality model could teach us anything about designing better reinforcement learning agents - https://t.co/62XgwSoT9R #ReinforcementLearning #AIethics #rl #AI

If you're attending @acm_ccs, pop by https://t.co/XEKuj1DC8J on Thursday. Our team has two papers on deep reinforcement learning for cyberdefence:

1. DRL for resilient drone communications (spotlight, presented by @hkscy at 10:50am)

2. Reward shaping for RL in cyberdefence (poster session, presented by Liz Bates)

The immense economic & societal damage caused by cyberattacks has increased interest in #AI-enhanced #CyberDefence.
📒 The Turing’s CETaS & @CSETGeorgetown researched a promising approach to creating autonomous cyber defence agents: reinforcement learning

@realhamed @TheO2 Does the front-facing camera work or is it just stuck on top of a regular screen?

[Chris Hicks @hkscy]

@tforcworc History helps...

@charliehrysmith The hard part is the #DigitalID needed to prevent Sybil attacks! Blockchains fall apart once you introduce claims or data that can’t be stored on the chain (I.e, anything other than a public key)

Ask Delphi: is centralised digital identity a necessary evil?
Delphi says: “it's expected”

Ask Delphi: Is outsourcing ethics acceptable?
Delphi says: “It's wrong”

Lots to ponder.

Ask Delphi: Centralised digital identity
Delphi says: “It's bad”

Ask Delphi: Use of centralised digital identity
Delphi says: “It's good”

cf. This looks tidy but was a pain to install and is difficult to remove! These low-cost devices are used by the majority in some countries e.g., in Sub-Saharan Africa. [2/2]

I hope someone else can appreciate how great the SIM placement is on this Nexus S device! Small victories...[1/2]
