The `check-if-email-exists` repository provides a Rust-based tool designed to verify the existence and deliverability of email addresses without actually sending an email. The project includes multiple ways to interact with it, including a CLI binary, a programmatic library for Rust projects, and a Dockerized HTTP backend that offers various verification features such as syntax validation, MX record checking, and SMTP server verification.
- Offers several modes: via CLI, through a Rust crate dependency, or using an HTTP/Docker backend.
- Verifies multiple properties including reachability status, disposable email detection, role account identification, and Gravatar URLs.
- Includes checks for "Have I Been Pwned?" to see if an email has been compromised in data breaches.
This article exposes critical flaws in Text-to-SQL benchmarks like BIRD and Spider. An audit of gold queries reveals that several contain incorrect joins, causing mathematically wrong results to be established as ground truth. Since standard execution accuracy measures performance by comparing outputs against these faulty reference answers, models are often penalized for being correct and rewarded for mimicking human errors. To address this, the author proposes a constraint-aware evaluation method that validates SQL logic against declared data semantics rather than relying on potentially incorrect gold results.

Agentic workflows are rapidly accelerating the volume of pull requests, and validation is quickly becoming the most critical bottleneck. Teams using service meshes like Istio are well-positioned to solve it in ephemeral environments.
var JSV = require("./jsv").JSV;
var json = {};
var schema = {"type" : "object"};
var env = JSV.createEnvironment();
var report = env.validate(json, schema);
if (report.errors.length === 0) {
//JSON is valid against the schema
}
