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.

persistent storage API on Firefox temporary extension
You can use File System Standard https://fs.spec.whatwg.org/ to write data for that origin (Firefox doesn't implement File System Access API, nonetheless a File object can still be written to local disk using File API).

I spent two years building a desktop environment that runs in the browser, it's finally in beta!
Both Firefox and Chromium (Chrome) have implemented WHATWG File System Standard.

SQLite WASM in the Browser Backed by the Origin Private File System
Can you just slow down for a moment and focus on what you said?
> We're literally in the discussion about File System API that is:
> - not on any standards track
As others have pointed out the standard is here:
https://fs.spec.whatwg.org/
> - considered harmful by other browser vendors
It is literally being drafted in conjunction by all the major browsers.
> - shipped by default in Chrome
So what? I for one am thankful that Chromium enables features earlier than other browsers. If you don't want the Chromium implementation then don't use it.

Show HN: I built a WASI playground for running CLI binaries in the browser
Score another point for memfs, the in-memory node.js fe impl.
WHATWG recently took up File System Access spec as their FS spec. It both looks semi promising, but they seem to only care about & are only building specs for specifically emscripten wasm users. Only sync apis, only usable from dedicated workers... there's some hopes for more latter but feels super weird to see the web finally get fs access & have it be fast... but for it to be extremely odd shaped hand tailored to a very narrow class of use.

I am curious. How many of you work on a windows system?
Now there are projects like WASI that allows for interfacing with system resources for WASM code this allows for devs to target WASM runtime for their apps sliding the apps to run locally on any OS without any porting required. This could be a game changer in the future like Docker and containers was in the past decade.

How to select some elements from array randomly?
So it doesn’t seem like there has been progress on a pseudo-random number generator function for typst, but there are multiple other ways to solve this: 1. Just don’t. Typst has this functional philosophy, there one input always produces the same output. (not an answer to your question tho) 2. Interface with a webassembly module which has a random number generator. So you could e.g. compile c to wasm and statically link a libc version. You would then just have to export the rand() function. (You could use any lang for this, which has a stdlib with a pseudo random number generator) 3. Implement your own. Random number generators are actually not that hard something like an LCG isn’t to complex. (Id provide an example but im on my phone rn)

Lapce Editor v0.3 Released
Actually WASI[0] will be a better alternative, IIRC extism serialize and deserialize the data that you want to pass every time, adding a lot of overhead.

Valheim: Regarding Mods
Proper isolation in C# is only now becoming a thing, with .Net support for WASI, which is essentially a WebAssembly sandbox which can be given extremely granular privileges (such as access to spefic file system directories, or an effective virtual file system). As an upside, the idea is that it should be possible to write the WASI packages in more or less anything.

Hardening Drupal with WebAssembly
Wasm Labs dev here :)
In mod_wasm, there are some differences with a pure CGI implementation. When Apache boots, it loads the configuration and initializes the WasmVM. When a new HTTP request arrives, the VM is ready so you don't need to initialize a different process to manage it.
You still need to process the request and pass the data to the Wasm module. This step is done via STDIN through the WebAssembly System Interface (WASI) implementation [0]. The same happens in the opposite direction, as the module returns the data via STDOUT.
So, the CGI pattern is still there, but it doesn't require new processes and all the code runs in a sandbox.
However this is not the only way you can run a Wasm module. In this specific case, we use CGI via WASI. In other cases, you may compile a module to fulfill a specific API, like ProxyWasm [1] to create HTTP filters for proxies like Envoy.

Extending web applications with WebAssembly and Python
The Python builds from the WebAssembly language runtimes [0] project target the WebAssembly System Interfaces (WASI) [1]. It allows the Python interpreter to interact with resources like the filesystem.
Many server-side Wasm runtimes supports WASI out of the box. For the browser, you need to provide a polyfill to emulate these resources like the one provided by the WASI team [2].
Regarding SQLite, these builds include libsqlite so you should be able to use it :)

How to Debug WASI Pipelines with ITK-Wasm
Effective debugging results in effective programming; itk-wasm makes effective debugging of WebAssembly possible. In this tutorial, adapted from the itk-wasm documentation, we walk through how to debug a C++ data processing pipeline with the mature, native binary debugging tools that are comfortable for developers. This is a fully featured way to ensure the base correctness of a processing pipeline. Next, we will walk through an interactive debugging experience for WASI WebAssembly. With itk-wasm, we can debug the same source code in either context with an interactive debugger. We also have a convenvient way to pass data from our local filesystem into a WebAssembly (Wasm) processing pipeline.

Running Go code inside a NodeJS app with WASM (Part 1/2, 2023)
Communication between the WASM module and the rest of the application needs to be done in very simple types (bytes, ints and floats). No complex types are supported yet. This is why most WASM compilers also provide some glue-code to map between complex types like strings or arrays. The Web Assembly System Interface (WAS) is an on-progress standard aimed to solve this last limitation; once it's mature it will allow easy interoperation with almost every environment. WASI is already available in some WSAM compilers and runtimes.
What are some alternatives?
node-postgres - PostgreSQL client for node.js.
wasm-bindgen - Facilitating high-level interactions between Wasm modules and JavaScript
file-system-access - Expose the file system on the user’s device, so Web apps can interoperate with the user’s native applications.
