Started working on an application to make it easy to see what parcels in NYC are upzoned with the City of Yes[1] changes that were passed last year.

I started off trying to make it a service to help people who are interested in ADU's get connected with architects/ contractors but spent a lot of time working on the interactive map to explore related ideas. The site is here buildbound.xyz and map here buildbound.xyz/map. Right now for example, it's very hard to tell if your site qualifies for the TOD upzoning portion of the City of Yes so maybe there is room to crunch those kind of numbers and provide it as a public service.

Trying to decide to keep going down the ADU route in NYC, even though the market is really early here, expand to NY State/ California where the ADU market is a bit further along or keep doubling down on making the best interactive zoning/ land use map in NYC and see if there is any product market fit to be found.

https://dbpro.app

We are working on DB Pro, a modern desktop data workbench for developers and data engineers.

The focus is on going beyond a query editor and building a complete environment for working with data. Visual exploration, inline editing, dashboards, and Jupyter notebook style workbooks for queries, notes, and experiments all in one place.

We launched v1 a few weeks ago and the reaction has been genuinely jaw dropping. Downloads, feedback, feature requests, and some great long form discussions around real world data workflows.

We are documenting the entire journey through a public devlog series. The latest video covers the v1 launch.

Honestly, building a desktop app is so refreshing after spending a decade or so building web apps.

I shared this last month, but I’m still having a lot of fun working on it. I made a daily word puzzle called Tiled Words. https://tiledwords.com Currently about 2,000 people play every day and I’ve released 59 puzzles! One feature I’m excited about is crowdsourcing puzzles. Today’s puzzle is a “community puzzle” made entirely from clues that players submitted! I plan to do this every week or two. I wrote about launch…

I really enjoy tiled words, thanks for making this new addition to my daily routine!

Still WithAudio https://desktop.with.audio . It's getting some attention and has actually sold licences!

Someone asked for a free license in exchange of detailed private review and bug reports. They have reported more than 10 bugs so far. I'm working on some of them right now.

WithAudio is a one time payment text to speech reader app. It's one time payment because it has no server and no recurring cost! A nice side effect of this is it's 100% private.

I resurrected some of my old code for computing hash collisions: https://github.com/DavidBuchanan314/birthday_party (it's actually more of a rewrite)

It can collide 96-bit truncated sha256 in under 24 hours on a 6700XT.

Next steps are a) figure out something interesting/useful to do with it (beyond surprising people), and b) modify it to support accepting contributions from untrusted clients (see "Future Ideas" in README). For a sufficiently interesting answer to a) I could create a "SETI@home"-like system.

A ~102-bit collision would cost $$ worth of rented GPU capacity, and 128-bit is optimistically possible with enough crowd-sourced compute (a ~5-figure dollar cost if you were renting).

I do a lot of word games (mostly crosswords.) This is great, congrats on launching!

I'm looking at how to introduce unique, borrowed and GC'd reference types into the IR for my VM/runtime.

I'm inspired by the language Lobster's compiler that specialises functions to arguments of either reference type as a way of doing something analogous to using "escape analysis" to allow objects to be owned by the stack. I think that perhaps specialised functions could be re-merged, with compile-time checks replaced with very cheap runtime checks taking advantage of "upper byte ignore" bits in pointers.

The VM will also need to support not just managed source languages, but also languages where unique and borrowed references are statically checked and possibly stored in objects.
