I do math. And was once asked by R. Morris Sr. : "For whom?"

Accidental two-time founder. Mathematician by education. Infosec luminary (has-been?).

I am insanely proud about the following, even though I am not at all involved any more:

Working with the optimyze team was so awesome.

OpenTelemetry Profiling Enters Public Alpha

Since OpenTelemetry first introduced Profiles, momentum has only grown towards building a unified industry standard for continuous production profiling, standing alongside traces, metrics, and logs. Today, the Profiling SIG is proud to announce that the Profiles signal has officially entered public Alpha, and we are ready for broader community use and feedback. Production profiling for all Continuously capturing low-overhead performance profiles in production is a technique that has been used for decades. It helps troubleshoot production incidents, improves user experience by making software faster and reduces computation costs by making the same work take less resources. Historically, the industry lacked a common framework and protocol for continuous profiling, even with formats like JFR and pprof being popular.

I wrote some lines about mitigating vibe-coding risks by adopting a development model inspired by old-school computer breakin folks:

Slightly safer vibecoding by adopting old hacker habits

I have seen a lot of public discussion around supply-chain attacks on the Python ecosystem, prompt injection risks when using coding agents,...

Artificial intelligence will have an impact not only on programming games for old machines, but also on the demo scene. Not a single line of Assembly code was written by humans for this #Atari8bit computers rotating toroid. EDIT it's a news, I don't like AI for demo scene prods.

Palantir’s Swiss Exit Highlights Global Data Sovereignty Challenge

Switzerland’s military has terminated its contract with Palantir Technologies Inc. following a security audit. The review concluded that U.S. intelligence agencies could potentially access sensitive Swiss defense data, a deal-breaker for the neutrality-focused Alpine nation. This move represents a significant reputational warning for the data analytics firm, with potential ripple effects across other international partnerships. […]

This post from Sean Heelan is probably the most important post in that domain (being LLMs in offensive security contexts) in quite a while. We're already discussing this in my research group, and I have some initial thoughts. Exciting times!

On the Coming Industrialisation of Exploit Generation with LLMs

Recently I ran an experiment where I built agents on top of Opus 4.5 and GPT-5.2 and then challenged them to write exploits for a zeroday vulnerability in the QuickJS Javascript interpreter. I adde…

@HalvarFlake Here’s some better alt text…

German claim to Greenland!

Giant German towel DROPPED ON GREENLAND!

German air force STRIKES!

US claims denied!

Expert says: “WHERE GERMANS LAY THEIR TOWELS, no one else is allowed to go!”

German towel rule in effect!

You can say what you want about the bubble — which I believe to be a thing — but unlike say web3, that technology is here to stay. I’ve rarely seen a technology go from fair attraction to magic that fast.

What a time to be alive.

One of my oldest and best friends posted a hell of an account of life in Minneapolis right now.

This whole thing rings so true. “A series of snapshots,” she says — and every one of us here is accumulating our own heavy stack of such snapshots.
