Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Spin 2.0 – open-source tool for building and running WASM apps
Joel from our team worked on the initial prototype for WASI support in TeaVM (https://github.com/konsoletyper/teavm/pull/610), and we temporarily forked before the WASI support made it to the official repo.
Good reminder to deprecate that now!

Bring garbage collected programming languages efficiently to WebAssembly
A number of concerns with the viability of the current WASM GC are covered here (Google translation to English):
https://habr-com.translate.goog/ru/articles/757182/?_x_tr_sl...
and the original article:
https://habr.com/ru/articles/757182/
This is from the author of TeaVM, who has 10 years of experience getting Java and JVM code to run efficiently in the browser. https://teavm.org/
TeaVM's existing transpilation of Java to JavaScript performs well (using the browsers JS GC). It will be interesting to see if WASM GC matures to the point where it is even faster.

Embed your Doom in Java with GraalVM Wasm.
How does this compare to say the TeaVM (https://github.com/konsoletyper/teavm) which I know only has "experimental" WASM support at the moment?

Regex101.com needs help getting a small Rust WASM binary
For Java, no WASM file is requested. Maybe the Java code was transpiled to JavaScript, perhaps using TeaVM.

Oracle Contributing GraalVM Community Edition Java Code to OpenJDK
>> It's not like you can take a random JAR and convert it to WASM.
Maybe you can:
TeaVM is an ahead-of-time compiler for Java bytecode that emits JavaScript and WebAssembly that runs in a browser. Its close relative is the well-known GWT. The main difference is that TeaVM does not require source code, only compiled class files. Moreover, the source code is not required to be Java, so TeaVM successfully compiles Kotlin and Scala.

I have never had an opportunity to try out TeaVM, but it seems promising.

Using Java for the front-end of a web app in 2022
For a fast, lightweight, Java-based front-end, try TeaVM and its Flavour toolkit:
https://teavm.org/
It is easy to get started by using the maven archtetype, there's an tutorial in Java Magazine here:
https://blogs.oracle.com/javamagazine/post/java-in-the-brows...
With TeamVM and Flavour you get a full front-end SPA framework that lets you code business logic in Java, and pair that with HTML and CSS to make components.
To see what it can do, check out Wordii, a fast-paced 5-letter word game:

Minecraft contains some native dependencies, though; you'll need something like https://copy.sh/v86/ or https://bellard.org/jslinux/ with the right operating system image to run it in browser.

SQL is syntactic sugar for relational algebra
> I completely attribute this to SQL being difficult or "backwards" to parse. I mean backwards in the way that in SQL you start with what you want first (the SELECT) rather than what you have and widdling it down.
> The turning point for me was to just accept SQL for what it is.
Or just write PRQL and compile it to SQL

Show HN: Open-source, browser-local data exploration using DuckDB-WASM and PRQL
Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w
You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload your own CSV/XLSX file. The tool runs fully in-browser—you can disconnect from the internet once the website loads—so feel free to use sensitive data if you like.
Here’s how it works: You upload a CSV file and then, explore your data as a series of successive data transforms and plots. For example, you might: (1) Remove some columns; (2) Apply some filters (remove nulls, remove outliers, restrict time range etc); (3) Do a pivot (i.e, a group-by but fancier); (4) Plot a chart; (5) Download the chart and the the transformed data. See screenshot: https://imgur.com/a/qO4yURI
In the UI, each transform step appears as a “Block”. You can always see the result of the full transform in a table on the right. The transform blocks are editable - for instance in the example above, you can go to step 2, change some filters and the reactivity will take care of re-computing all the cells that follow, including the charts.
We wanted Pretzel to run locally in the browser and be extremely performant on large files. So, we parse CSVs with the fastest CSV parser (uDSV: https://github.com/leeoniya/uDSV) and use DuckDB-Wasm (https://github.com/duckdb/duckdb-wasm) to do all the heavy lifting of processing the data. We also wanted to allow for chained data transformations where each new block operates on the result of the previous block. For this, we’re using PRQL (https://prql-lang.org/) since it maps 1-1 with chained data transform blocks - each block maps to a chunk of PRQL which when combined, describes the full data transform chain. (PRQL doesn’t support DuckDB’s Pivot statement though so we had to make some CTE based hacks).
There’s also an AI block: This is the only (optional) feature that requires an internet connection but we’re working on adding local model support via Ollama. For now, you can use your own OpenAI API key or use an AI server we provide (GPT4 proxy; it’s loaded with a few credits), specify a transform in plain english and get back the SQL for the transform which you can edit.
Our roadmap includes allowing API calls to create new columns; support for an SQL block with nice autocomplete features, and a Python block (using Pyodide to run Python in the browser) on the results of the data transforms, much like a jupyter notebook.
There’s two of us and we’ve only spent about a week coding this and fixing major bugs so there are still some bugs to iron out. We’d love for you to try this and to get your feedback!

Pql, a pipelined query language that compiles to SQL (written in Go)
> Looks like PRQL doesn't have a Go library so I guess they just really wanted something in Go?
There's some C bindings and the example in the README shows integration with Go:

Vanna.ai: Chat with your SQL database
https://prql-lang.org/ might be an answer for this. As a cross-database pipelined language, it would allow RAG to be intermixed with the query, and the syntax may(?) be more reliable to generate
