I am working on climate repair, specifically the removal of methane from the atmosphere. Although the excess methane is only about 1.3 ppm, it's responsible for about a third of the temperature rise. We're not building a huge machine to try to suck the atmosphere through a straw; we're doing chemistry in the open atmosphere. Plan to have a pilot running within the next year and within five years be removing up to 100…

That sounds interesting. How do plan to fund that? 100mt a year of sequestration sounds like there would be a fair amount of costs and labour involved.
There are people who pay for GHG removal and we have plans on how to expand that. We think it can be self-sustaining.

#484A keyboard based IDE for a keyboard based GUI for PCs. Common PC GUIs are WIMP based (Windows, Icons, Menus, Pointers). They require the usage of a mouse and are pretty complicated. I find the usage of the mouse in a PC GUI "unnatural". So I set out designing a keyboard-input only based GUI. It turned out, that wasn't as difficult as I initially thought. Then I started writing an IDE for designing apps using this new…

#486Javascript and ORMs have a (fairly well-known) interesting set of problems: * There aren't many * Those that you can find, don't support Typescript, so it's all guesswork. * Don't have much (if any) support for related data queries So I've been working on a ORM for PostgreSQL and Typescript for a few months now in my spare time [0]. It's been probably one of the biggest, challenging, and interesting problems I have e…
I’m interested to hear what those PostgreSQL limitations are more specifically.
The rabbit hole goes.

How big is your index and how many sites do you cover?
1 million websites, a bit above 60 million documents in the index; the crawl is a couple of hundred million but a lot of it gets filtered out for various reasons. The crawler itself is aware of 470 million URLs. I've actually had it up to 50 million before, but that was a lot noisier data with fewer keywords per document. The current 60 million is significantly "bigger" than the old 50 million. Index size is not actu…

#489A postgres foreign data wrapper for PACS so you can send and receive medical images with SQL. DICOM, the medical imaging standard, is from the 80's and you need a bit of domain knowledge to integrate e.g. AI with hospitals. This makes it a lot easier. And with Supabase on top you have a very cool backend for building medical imaging products in my humble opinion. We started out solving the problem of anonymizing medi…
Probably socialized medicine nations are not progressive enough to attempt this.

#490the current site texts you when shows matching your preferences are about to start. the next iteration will have visualizations of the music being played by each station in close to real time and allow you to select between them, save them, etc. the visualizations will be updated each minute and colors will be selected by the HSL color system, where hue = tempo (from blue for slower to red for faster), saturation (or intensity of color) = loudness, and lightness = pitch (technically, spectral centroid or 'center of mass' of frequencies of music).
i also want the ui to allow people to select from stickers i've taken pictures of around nyc and arrange them similar to concert venue bathrooms or middle school lockers haha.
altogether, want to create a fun way to explore independent radio!
