Context:
-
TinyGo is a Go compiler designed for small environments like microcontrollers, WebAssembly (wasm/wasi), and command-line tools.
-
It utilizes Go language libraries and LLVM to offer an alternative method for compiling Go programs
-
-
Changelog highlights:
- Go 1.23 support (including the new range-over-func language feature)
- ...
-
Context:
- An extremely small, "fast enough" vector search SQLite extension that runs anywhere.
- Store and query float, int8, and binary vectors in vec0 virtual tables
- Written in pure C, no dependencies, runs anywhere SQLite runs (Linux/MacOS/Windows, in the browser with WASM, Raspberry Pis, etc.)
- Pre-filter vectors with rowid IN (...) subquerie
- An extremely small, "fast enough" vector search SQLite extension that runs anywhere.

Usage:
go get -u github.com/asg017/sqlite-vec-go-bindings/ncruces
package main
import (

"log"
_ "github.com/asg017/sqlite-vec-go-bindings/ncruces"

log.Fatal(err)
}
stmt, _, err := db.Prepare(`SELECT vec_version()`)
if err != nil {
log.Fatal(err)
}
stmt.Step()
log.Printf("vec_version=%s\n", stmt.ColumnText(0))
stmt.Close()
}

-
Permify is an open-source authorization as a service inspired by Google Zanzibar.
-
Centralize & standardize your authorization: Abstract your authorization logic from your codebase and application logic to easily reason, test, and debug your authorization. Behave your authorization as a sole entity and move faster with in your core development.
-
Build granular permissions for any case you have: You can create granular (resource-specific, hierarchical, context aware, etc) permissions and policies using Permify's domain specific language that is compatible with RBAC, ReBAC and ABAC.
-
Set authorization for your tenants by default: Set up isolated authorization logic and custom permissions for your vendors/organizations (tenants) and manage them in a single place.
-
Scale your authorization as you wish: Achieve lightning-fast response times down to 10ms for access checks with a proven infrastructure inspired by Google Zanzibar.
