Welcome to 0x0x - A Site for Righteous Interfaces
This site is dedicated to protocols and services designed to appeal to hackers ("hackers" in the original sense -- people who love coding and making things happen with computers).
We publish information about simple and interesting technologies and efforts that merit attention from the community of geeks who live and play on the internet, and also run some services to let us play with these ideas.

2025-12-21 - Shortener
Mammies little baby loves shortening, shortening!
Yeah, sorry. So I cleaned up my url shortener so it can be more easily used from the site (you need to be a registered user to create URLs, but you can see an example at https://0x0x.dev/s/SXu_, which links to the bitcoin genesis transaction on blockchain.com).
I ran into some problems deploying it here. This application server runs in a docker container, and dockerd was consuming a huge amount of memory and commands like "docker ps" were hanging. It looks like I triggered a startup loop at some point during the deployment, and the docker daemon must have accumulated a large number of containers. docker system purge finally fixed it after running for quite a while, but we actually saw a fair amount of downtime over the past week while I was sporadically trying to fix this.
2025-09-21 - NOSTR
I've lately been messing around with NOSTR. What I like most about it is that it's pretty close to what I would have implemented - users are defined by cryptographically secured profiles (your identity is your public key) and all of the information is hosted on relays.
It's basically uncensorable. As long as there are relays that are willing to host your information no one can prevent you from publishing it.
Another interesting property is its inherent association with Bitcoin. Most of the crypto and address standards come straight from the BIPs, and so many people who post on the network are BTC-maximalist crypto-anarchists. I feel right at home.
2023-03-06 - PHP Tiny Blog Engine
I recently met user Turboblack from rawtext.club and he shared his PHP Tiny Blog Engine link with me (download as a zip file from the link in red).
2023-01-22 - Generated Blogs and RSS
I've just finished a first round of improvements of the news feed on this
server (that's the thing containing the text you're reading right now :-)). Now
new posts are generated from simple text files. Full versions of a post can be
independently linked and there's a dedicated news page and
an RSS feed.
