24 alternatives to Should – Expressive Assertions for Go
A few months ago I posted this here. Since then I've added a bunch of new assertions: BeSorted, BeSameTime, BeWithin, BeError/BeErrorIs/BeErrorAs, formatted custom messages, and some renames for clarity. The core idea is still the same — when a test fails, you should immediately know why without having to add debug prints. https://github.com/Kairum-Labs/should

Hey HN! I built Gojju, a programming language that cherry-picks my favorite features from 5 languages: - Python: List comprehensions, slicing - Ruby: #{interpolation}, postfix if, blocks - Haskell: |> pipe operator, lambdas \x -> x+1, Maybe/Either - Perl: unless/until, regex literals - JavaScript: Arrow functions =>, spread ... Example: [1, 2, 3, 4, 5] |> filter(\x -> x % 2 == 0) |> map(\x -> x * 2) |> sum Install: `pip install gojju` The name "Gojju" (ಗೊಜ್ಜು) means "essence" or "secret ingredient" in Kannada. Would love feedback on the syntax choices!

We explored a novel method to gauge the significance of tokens in prompts given to large language models, without needing direct model access. Essentially, we just did an ablation study on the prompt using cosine similarity of the embeddings as the measure. We got surprisingly promising results when comparing this really simple approach to integrated gradients. Curious to hear thoughts from the community!

Learn how to write Rules Engines with CLIPS in your browser! I found the Tour of Go super useful when learning Go, so I went for something similar for evangelizing the awesomeness of CLIPS. A few things I'm proud of with this project: - No front-end frameworks - Compiled WASM binary; your code isn't sent to a back-end server - Code editor/syntax highlighter written from scratch (that I'm sure you'll find bugs in ;)) This is my first attempt at this, and I'd like to expand on it in the future. Let me know what you think! About CLIPS: CLIPS is a programming language useful for building…

Hello, everyone. Three months ago, I started building my first GoLang package, VarMQ. In this short period, I gained a significant amount of traction from the community, and it resulted in over 140 stars on GitHub. A week ago, to check how it performs, I ran benchmarks with a similar package, Pond, which has been managed for years. Pond is not a message queue, though; however, it can be compared to VarmQ since it shares some similarities, except for its storage system. From the benchmarks, I got surprising results, which are that Varmq is taking 50%+ less memory than Pond and also has good…

Hey folks, wanted to show this off and get feedback. Still early/experimental but there are quite a few concepts I'm excited about here. This project came about while writing a program in Go and loving its approach to concurrency. Being a long-time Rubyist I immediately started to think about what similar concepts might look like in Ruby. I set out with two main design constraints: 1. Lightweight: I didn't want routines to be backed by fibers or threads. Having been involved some in the async project (https://github.com/socketry/async), I had some experience using…
