In plain words
WhatsApp Login is an authentication service that lets app and website developers add WhatsApp-based login to their platforms. Instead of using one-time passwords, users sign in through WhatsApp for a faster, more secure experience. The integration is straightforward, requiring just a copy-paste link on login pages. It's designed for developers looking to streamline user authentication and potentially increase conversions.

One SDK runs every identity moment on mobile — auth, device trust, address, payments, and fraud — without OTPs, without friction.
From the first tap to every transaction, OTPless handles identity invisibly - without an OTP in sight. Real-world identity stacks running in production, across India's category leaders. Every identity moment, shipped as part of one integration - from carrier verification to fraud signals. SNA verifies SIM possession in the background by talking directly to the carrier. No OTP screen. No SMS to fetch. No "didn't receive a code" panic. The user does nothing — and they're authenticated. You can choose a phone number that's assigned to your phone, and Google will share it only with this app. Mobile Auth picks the channel that's actually working right now — by success rate, latency, and operator…from otpless.com

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma... Girl with a pearl earring: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma...

The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
