It started with me trying to get weather stats for my city, to give proof to the nagging thought 'Has it really gotten this hotter in the last X years?'
Now its aiming to be a project where one can visualize historical weather data for any place with a lot of stats and trendlines
Still in active development - right now the visualization only has my town in it.
It’s crazy how much time developers waste tweaking hardcoded prompts, writing endless test cases or constantly shift focus between building LLM features and verifying them. It’s usually the product person who should be handling this.
To scale a product, you need an extra set of eyes to double-check the engineers' work before it goes live.
Just want to give non-technical folks the power to test and improve LLM apps themselves!
This project is called https://ottic.ai/
Working on an alternative to character.ai, they recently updated their UI and a lot of the fan favorite features are gone. https://makebelieve.lol
Would suggest better AI model images on the homepage Flux models look far better than these older stable diffusion ones
Now I am a bit afraid I might have just added a bit too much flexibility in the latest version with the `process` module which truly lets users create and modify 'function-like' objects like regular objects (arrays).
The feature came naturally from trying to solve the problem of creating reactive functions. This really entails building up functions incrementally. Now once I pursued the solution in the logical direction, we have this dangerous thing that is generally considered bad for maintainability.
My goal has always been more simplicity, expressiveness and clarity, which is why I wanted to put everything in the hands of the end user. It is a dilemma.
I'm working on JSON BinPack ( https://jsonbinpack.sourcemeta.com ), a binary serialization format for JSON (think of it as a Protobuf alternative) with a strong focus on space-efficiency for reducing costs when transferring structured data over 5G and satellite transceivers for robotics, IoT, automotive, etc. If you work at any of those industries and pay a lot for data transfer, please reach out! I'm trying to talk…
Don't know if you'll see this, but I really like your work. I read your dissertation at least twice, it's well written and informative. In my day job I have multiple large json files, used in an internal in-house application, into which I serialize a database, and working with them is much faster than using the database (for some workloads). Although the main reason to do so is just for using git for source control.…
> By the way, in your dissertation you don't mention RapidJson, nor json.net, nor simdjson. Is there a reason why you didn't compare them?
My research was focused on space-efficiency more than parsing performance, so I didn't talk about that problem. However the long-term goal is that by using JSON BinPack's binary encoding, you should have a better time parsing it, as you don't have to deal with the JSON grammar.
Do you do JSON Schema validation too?
Easy Data Transform v2 ( https://www.easydatatransform.com ). It is GUI based data wrangling tool for people who aren't (or don't want to be) programmers. 20 years of running a 1-man software company in January.
I bought V1. Is there an upgrade path to V2 for existing customers?
I've been experimenting with customizing Postgres to run on top of FoundationDB, which to me would be the dream combination of Postgres' top-notch feature set and ecosystem with FoundationDB's unique resilience, scalability and transactional guarantees. Haven't written up anything about it or published any code yet, but it's working pretty well and I haven't even had to fork Postgres with all the extensibility it off…
If not, and you're trying to go more directly for FDB-KV, I hope you're aware of https://www.voltactivedata.com/blog/2015/04/foundationdbs-le...
I'm writing a Postgres-wire-protocol-compatible OLTP database in Rust, using RocksDB for storage as a starting point (MVCC for free!), worrying right now more about correctness and test coverage than performance. But I definitely feel their point of wanting more granular locking at some point.
A website that sorts the recent Peloton bike rides by difficulty. https://pelohard.com/ I love my Peloton and it was really annoying finding a ride with a difficulty over a certain threshold that was recent. I'm an embedded developer by day and did this with a lot of help from ChatGPT and Claude. Hoping to add some more features to it as time goes on.

I assume you're thinking of using FoundationDB as a page store, much like https://github.com/neondatabase/neon uses S3?

Actually not, I'm replacing Postres storage entirely down to the tuple level with FoundationDB instead. Neon is really cool but you would lose out on the greatest part of FDB, the transaction processing, if you were to simply use it as a page store (S3 and friends is probably a better fit for something like that).

Hadn't seen that before, thanks for linking! Remains to be seen how well I can get this to work although one interesting thing to note is that CockroachDB (which would be the closest thing to what I'm building) is also built on top of a distributed KV store, although one built into Cockroach.

Same at the moment in terms of what to focus on! What excites me the most about my project is the idea of making actual Postgres become seamlessly fully distributed, like Cockroach but not just Postgres-compatible.
Would love to hear more about your project, have you published anything on it?
I spent a week building a website that is a repository of timeless content. It generally consists of old magazine articles (though not exclusively) that you can pick up at any time and will bring value to your life. I notice most of what we consume on daily basis is ephemeral and not all that valuable outside of the moment, whereas ever-present content is always valuable. The unique angle here is that each article in…
