Agentic Commerce and Payments

Giving agents the ability to pay

Link’s wallet for agents gives agents programmatic access to Link, including the ability to generate a one-time-use card or Shared Payment Token (SPT) backed by the cards and bank accounts already in your wallet. It’s built on Stripe’s new Issuing for agents.

Jimmy Angelakos: PostgresEDI April 2026 Meetup Recap & May Lightning Talks

Another great evening for the PostgresEDI community! 🐘 First off, a massive thank you to everyone who came out to our April meetup. The discussions were brilliant, and it's amazing to see new faces come to experience the friendly environment at our meetups. Hugo Tunius presenting at the April meetup. We had a fantastic technical dive this month, with Hugo Tunius taking the stage to talk about plid — a custom ULID-inspired ID type with prefix support that fits in 128 bits, which he bui...

The USB Situation

I write this from the latest MacBook Pro. I’ve been running this as my primary machine for almost a month. When I’m not grinding out the latest soon-to-be-released I-swear-I-am-on-schedule book in a coffee shop, I sit at my desk and plug the MacBook into a Studio Display. This braided black cable does it all: video,… more

Fragments: April 29

Chris Parsons has updated his guide on using AI to code. This is his third update, what I like about it is that he gives a lot of concrete information about how he uses AI, with sufficient detail that we can learn from him. His advice also resonates with the better advice I’ve seen out there, so the article makes a good overview of the state of using AI for software development. I wrote the previous version of this post in March 2025, updated it once in August, and it has been linked fr...

Razorpay Oncall Agent: From 30-Minute Investigations to 90-Second AI Analysis

Our on-call engineers were spending 30 minutes investigating every production alert. Here’s what happened when we automated it.At 3 AM, alerts don’t care about your sleep schedule.When our payment infrastructure threw an error last month, our on-call engineer spent 32 minutes jumping between six different monitoring systems before understanding what was broken. One tool for metrics. Another for logs. Third tool for pod health. And multiple more for infrastructure, deployment history and d...

Stefanie Janine: PostgreSQL Ecosystem Problems

PgBackRest Is Dead Yesterday the maintainer of PgBackRest, David Steele, published the NOTICE OF OBSOLESCENCE. For further information please read the blog post pgBackRest is dead. Now what? by Lætitia Avrot. She also points to how to go an as she, like me, always recommended PgBackRest for PostgreSQL backups. Therefore a big thank you goes for the work David has done on PgBackRest. And Now What? Things alike happened before, for example when due to the liquidation of the Segfault Inc. M...

V.O.I.C.E (Voice, Ownership, Identity, Control, Expression): Risk Taxonomy of Synthetic Voice Generation From Empirical Data

arXiv:2604.24794v1 Announce Type: new Abstract: As generative voice models are rapidly advancing in both capabilities and public utilization, the unconsented collection, reuse, and synthesis of voice data are introducing new classes of privacy, security and governance risk that are poorly captured by existing, largely uniform threat models. To fill the gap, we present V.O.I.C.E, a taxonomy of voice generation risk grounded in a multi-source threat modeling effort with 569 incidents from majo...

Semantic Denial of Service in LLM-controlled robots

arXiv:2604.24790v1 Announce Type: new Abstract: Safety-oriented instruction-following is supposed to keep LLM-controlled robots safe. We show it also creates an availability attack surface. By injecting short safety-plausible phrases (1-5 tokens) into a robots audio channel, an adversary can trigger the models safety reasoning to halt or disrupt execution without jailbreaking the model or overriding its policy. In the embodied setting, this is a semantic denial-of-service attack: the agent s...

Cloud to Edge: Benchmarking LLM Inference On Hardware-Accelerated Single-Board Computers

arXiv:2604.24785v1 Announce Type: new Abstract: Large language models (LLMs) are becoming increasingly capable at small parameter scales. At the same time, conventional cloud-centric deployment introduces challenges around data privacy, latency, and cost that are acute in operational technology and defence environments. Advances in model distillation, quantisation, and affordable edge accelerators now make local LLM inference on single-board computers feasible, but the high dimensionality of...

Formalizing the Real Numbers in Homotopy Type Theory with Cubical Agda

arXiv:2604.24782v1 Announce Type: new Abstract: Real numbers in constructive mathematics have always seemed to require compromises of one form or another. Classical proofs of Cauchy completeness require countable choice, Bishop's setoid construction introduces persistent bookkeeping overhead on every definition and theorem, and Dedekind cuts force cumbersome universe-level tracking in predicative type theory. The Homotopy Type Theory (HoTT) book presents an alternative construction of the Ca...
