I had a chance to sit down and read Tor: From the Dark Web to the Future of Privacy by Ben Collier

I highly recommend it. I think it captures the history beautifully and its a nice reminder of how these projects play out over decades.

It can be very easy to get caught up in the day-by-day/week-by-week rush/drama/critiques/effort and having a history like this puts that nicely in perspective.

Go read it.

A list of research/project ideas that I have no time to pursue fully, but which I would be very interested in helping out/mentoring. If any of these sound interesting then please reach out to me. I may also be able to help find funding for some of these.

1. File Metadata Removal - this is an area that I think needs additional reseach/experimentation. Existing solutions like exiftool and MAT/2 are great, but don't quite match the modern reality for when and how we would ideally like to integrate such processes into tooling (e.g. in a chat app file share flow) and I think suffer from a limited view of file metadata in light of the growing complexity and diversity of file types, and web based workflows - and how people realistically want to check/modify/remove metadata.

Further, we now have interesting approaches like Magica and other approaches that can perhaps be utilized to catch file types and metadata not strictly captured by a given tool.

Realistically I think there are like 4-5 distinct research projects here around UI/UX, requirements and expectations, and new technical work.

2. Reproducible Build Tool - I'd love to find someone interested in helping/expanding replqiate. I have some ideas about speeding it up further, pushing back the trust, and getting it to the point where it functions as a day-to-day build tool.

3. A better (mostly-static) source code repo/forge - One of my biggest sources of frustration right now is spam in source code repos: specifically issue spam, pull request spam - I think I delete at least 5-10 AI-generated nonsense a week. It's getting worse and the moderation tools to catch this are terrible. I would really like a mostly static git repo that also allows moderated public-issue creation and other nice features. I have a prototype but its been gathering dust.

4. Small Groups (multi)-Project Management - I work on a lot of projects where the primary team is small (either just me, or a small group of 2-4). I have used every project management tool under the sun and found none of them really fit the flow I want. A few notes:

- Kanban is great for restricting WIP but a tool that manages everything in terms of kanban/boards is terrible for managing longer term research

- I need a place to put papers/documents/artifacts that can be tied and referenced to active issues

- I'd like to be able to breakdown problems in addition to work. Capturing the problem structure is, to me, just as important as tracking the work needed to solve a particular instantiation of it

5+. While I am actively working on projects in the following areas, if any of them sound interesting please also get in touch:

- Decentralized Search

- Formal Requirements Specification

- Evolutionary Fuzzing

- Cwtch / Privacy Preserving Communication

I spent some time improving Saffron, a formal language I've been working on aimed at requirements elicitation and analysis.

Mainly I've been thinking about how to express common "patterns" in the underlying formalism e.g. "A message has a single author" can be expressed as infer WHERE m:Message a:Actor b:Author MATCH Author(m,a) THEN PROHIBIT Author(m,b).

One of my goals for this week is to document some of these patterns, and perhaps allow them to be expressed in a syntactic sugar e.g. the above is perhaps more nicely expressed as constrain WHERE m:Message a:Actor EXCLUSIVE Author(m,a)

(An even better syntactic sugar might be to allow the construction of meta-types that compile down to such relationships under the hood to allow a more programmer friendly representation e.g. struct Message := { Author Content } though I am less inclined towards that direction right now as it clutters the number of formalisms at the highest level.)

Hello World!

I've been thinking about where microblogging/blogging fits in my life.

I used to write a lot of Twitter threads, but since the implosion and my move to Mastodon I write far fewer than I used to. Part of this is the difference in platforms, part is my own changing priorities.

For a while I maintained a personal blog for longer term thoughts but I've found it clashes with how I want to organize my thoughts. I often update old articles, redraft papers, rewrite systems etc. and so a few months ago I started writing this website, in a text editor, with no overarching taxonomy or categorization.

However, this obviously comes with some downsides, which I'm now looking to address.

Inspired by Molly White, I've implemented this Activity Feed. A place for me to microblog, collect thoughts, post links, document website updates, new papers etc. all in one place, and in a format that I have a bit more control over.

I'll probably expand the little script I wrote to compile this, and publish it once it is in a less hacky state. But it already compiles to a feed, has tag categories, and is nicely integrated with the rest of my little static site.

There is no automated cross-posting, some of the stuff posted here will end up on Mastodon etc. but most will not. This is mostly for me, but if you would like to keep track of things I am working on, then this is the place.
