Ask HN: How the hell haven't we solved phishing emails yet?

Tue, 05/20/2025 - 5:47pm

How is it possible that in 2025 with all the amazing advancements in AI, I am still getting phishing emails? Emails attempting to look as if its coming from Coinbase, or some stock broker, or bank, or even UPS/USPS/FEDEX? These emails dont look even remotely legit so how do they manage to pass through? Even the email addresses are from some completely different domain. I am using Outlook and Gmail. How/why have they not figured this out already? Even ignoring AI, I don't know much about email but why isn't there something like a CA for email?

Show HN: A Simple Server to Match Long/Lat to a TimeZone

Tue, 05/20/2025 - 5:43pm

I figured this might be useful to folks.

It's a simple PHP server that requires a single-table database (It's fairly "agnostic," but all my uses are in MySQL).

I won't publish any of the servers that I've set up for my apps, because someone is bound to write an application that drives my bandwidth into the stratosphere.

I could definitely take it further, but this gives me all I need for my purposes.

Here's an app I wrote, that uses it: https://apps.apple.com/us/app/we-are-never-alone/id650482602...

Show HN: I made IP-to-Geo location data library for developers

Tue, 05/20/2025 - 4:48pm

I made this lib called Ip2Geo — it's a super-lightweight, type-safe library that lets you convert any IP into geolocation data. It's 100% free with unlimited uses—no catch. It works online only and runs on both the client and server.
