Anyway, your problem isn‘t finding the time to take notes. The problem is that taking notes is thinking and thinking has to be done by someone. women have been doing a lot of metacognition that looks like a task when it’s really thinking.

I'm looking for a job! I'm an experienced researcher in cryptography. My focus is on the transition to post-quantum cryptographic protocols and protocols related to blockains. If that sounds like someone you might want to hire or you know someone who might, let's talk!

The Workshop on Attacks in Cryptography 8 (WAC8) website is finally up, and our call for talks is open. Submit your cool cryptanalysis before July 3! We'll also invite speakers. If you had a favorite cryptographic attack from the last two years that we should invite, please put it in the comments.


call for talks

WAC accepts proposals for contributed talks. Submissions will be evaluated based on their relevance to the following topics:
- Cryptanalysis of deployed cryptography
- Cryptanalysis of recently suggested cryptographic schemes or primitives
- New cryptoanalytic techniques
- Systems attacks breaking cryptography or bypassing underlying assumptions

Please include the following information in your contributed talk submission.
- Title.
- Description of the talk content, including: short abstract (to be published on the website on talk acceptance), and one of the following three: extended abstract describing the talk. [preferred option], a full paper and a short description of which aspects the talk will focus on. slides for a presentation, together with either speaker notes or a short outline of the non-visual content of the talk.
- Speaker information: Name, Affiliation, Short bio (to be published on the website on talk acceptance), A brief description of the relevant experience of the speaker, e.g. links to previous talks.

Submit your proposal by email to the organizers at wac@cryptanalysis.fun by July 3, 2026 AoE.

UNSW Sydney is hiring an associate professor and a lecturer in cryptography, and the description explicitly mentions *secure computation*. Didn't you want to live in the sunniest of the most livable cities in the world?

Teaser: a colleague (Sasha Rubin) and I are planning a 3-day (free) "intensive Winter school" at #USyd on computational complexity: specifically, interactive proofs (IP=PSPACE) and the PCP theorem. July 22-24! I don't know how many people here are nearby and keen, but if you are: please do join!

Very insightful short essay by Petra Schwer ( mathstodon.xyz/@PetraSchwer ): ‘The meaning of doing mathematics’ “(Can AI solve all math? What do we actually mean by doing mathematics? How do we communicate mathematics? What is mathematics beyond problem solving?)” arxiv.org/abs/2509.15998

The meaning of doing mathematics

You may find the comments by Melanie Matchett Wood on the discovery of a counter example to Erdős’ Unit Distance Conjecture as interesting as I did 👇🏼(see previous post for a link)

A screenshot of p.17 of the paper available at https://cdn.openai.com/pdf/74c24085-19b0-4534-9c90-465b8e29ad73/unit-distance-remarks.pdf

The OpenAI breakthrough on the unit distance problem seems genuinely impressive to my semi-layman eye. (It is!) One possible takeaway, though, is that if you throw an incredible amount of money and resources at focused research, there WILL be impressive progress. I wish we tried that, too.

I think the screenshoted take is insane. If a mathematician discovered something with Matlab, if a scientist uses an algorithm, if a designer uses Adobe, if anything like that, the work belongs to the user. But big tech companies have been trying to claim the work of their users for a decade now.

culturally this bit is blowing my mind a bit (and may be what @radokirov.bsky.social alluded to in his last blog post). i would think that the achievement is the result itself, and the credit “belongs” to the prompter for making it known to the world, whatever the tools and means

My time at RUB is coming to an end and I'm looking for an industry position. Primarily looking for remote or Rhine-Ruhr area positions, but will consider any exceptional offers. So if you're looking to hire a cryptographer to work on cryptographic protocols, or related areas, maybe we should talk!
