biscuit-based identity and authorization I’m working on https://www.hessra.net/ , an identity + authorization service built around [Biscuits]( https://www.biscuitsec.org/ ) instead of JWTs. The goal is to decompose auth primitives so they’re easier to use in service-to-service cases, while also showing off what Biscuit tokens make possible. JWTs feel like problems waiting to happen. I think biscuits give stronger gua…

Are Eclipse Biscuits related to Google Macaroons? https://research.google/pubs/macaroons-cookies-with-contextu...

(what a word salad that is...)

I've been working on a tool called Materia[0] for managing Podman Quadlets on hosts, GitOps style and I think it's really starting to hit its stride. I just released a new version yesterday: https://github.com/stryan/materia/releases/tag/v0.3.0 .

There's been a couple attempts in this space before but they usually seem to peter out after a while. I'm hoping to avoid that by staying flexible and focusing on just managing files instead of creating a new compose-like DSL. But even if it doesn't become popular I'm just happy I don't have to manage my homelab with Ansible anymore :) .

vulnerability discovery and exploitation, with zero false positives.

https://vyprsec.ai/

Yep, you read it right. 0 false positives. We scan the whole codebase for possible vulnerabilities, rank them, write the proof-of-concept for exploitation, spin up the software in a sandbox, and then attack. All of them happen autonomously without human involvement.

The end report? Only verified vulnerabilities are being reported without noise.

Already reported some unknown vulnerabilities in open source projects. The good thing is we're just getting started.

I'm toying around with a language that's like Python but with Hindley-Miller interference and some functional stuff. It's not a superset or anything, because I can't do that, but it's interesting how well HM (plus some well-encapsulated escape hatches) map onto the Python ecosystem with all its dynamism.

https://spanara.app Spanara - A word game inspired by the "license plate game" my wife taught me while we lived in Finland. License plates in Finland always start with 3 letters, so out on our walks we'd try to come up with a word quickly, and got more kudos for "good" words. This was a first attempt at a personal project using AI. I am currently working on a new mode that is more like what played walking around: a f…

Seems like a really small dictionary. Many/most of my guesses (and Gemini's) don't work.

Yeah, sorry about that, and thanks for the heads up!

I've struggled with the dictionary a few different times. Here's to hoping the 12dicts wordlist 2of12inf is a better choice than my previous ones :D

The new dictionary is live!

Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

I LOVE this idea. Tangentially, a more pimitive case: in trying to recycle or reuse jars or carboard containers food comes in, I wish there was a simple service for ranking brands. For example, some jam jars have labels that can be immediatey removed - others tear and stick to the jar. Similarly, some brands use excessive plastics and packaging, others less so.

Updating my validation library for python, koda-validate ( https://github.com/keithasaurus/koda-validate ). Focusing on ergonomics improvements. Just released an improvement to the __repr__ for Invalid types. Potentially working on expanding the ability to generate validators from arbitrary typehints, ie `get_typehint_validator(list[str | int])`. It has good coverage, but I suspect I'm blind to some obvious holes. Wo…

Pydantic already covers type-driven validation and it works well enough. What is the main value add in Koda? Just curious.

It's not the core of koda-validate, and yeah lots of libraries have a similar capacity. Feedback I'd be interested in is if there are gaps.

In general the value prop of koda-validate is that it turns validation into typesafe building blocks, which makes validators very re-usable -- and flexible. Some other notable differences from pydantic are that it doesn't `raise` on validation errors, you don't need a typing plugin, and it's fully asyncio-compatible.
