Ask HN: What Are You Working On? (December 2025)

The goal is simple: if you search for something specific, you shouldn’t have to scroll through ads, “inspired by your search”, or completely-irrelevant junk. You should just only see products that actually match exactly what you’re looking for.

Right now it searches across a few large stores and I’m iterating on the ranking and filtering. If you buy a lot of stuff online, I’d love feedback on where the results feel clearly better, and where they still fail compared to Amazon/etc.

It's an AI-native email client. Launching soon!

My goal is to help people get done with email faster, so that they can get back to doing other stuff. A lot of the features are designed around this goal: unified inbox, AI summarization, AI email drafting, etc.

Some of these are table stakes but I think there's also an opportunity to significantly revamp how email is done in the AI age. Imagine having your own personal assistant that goes through your email and surfaces the highest priority things that you need to know automatically.

Trying to build a small-scale ISP/hosting provider domiciled in Canada. We really want to be able to rent real rack space to enthusiasts who would like to benefit from having stuff in the datacenter but don't want to take on the opportunity cost to get started. It came out of my own desire to have a machine in a DC rack.

This week we've been writing a bunch of "reviews" of self-hostable software since a lot of our friends are curious about this space but don't have a good understanding of how to get started. https://blog.colocataires.dev.

This is still in development (todo are privilege dropping, in place config reloads, log burst suppression, multiple listen sockets (which paired with the Linux kernel gives free load balancing capabilities), and detailed TLS configurability), but it already matches both nginx and HAProxy’s speed (entirely bottlenecked by OpenSSL crypto by this point) at a tiny fraction of the attack surface and memory footprint (10-15kb per worker process last time I checked).

If anyone wants to take a look, please roast my code :)
