Working on a project: https://hpyhn.xyz. It's a website for analyzing posts and comments on HN. The idea started as a way to help me learn from discussions and filter out posts I don't interest in.

#363I'm playing around with sandboxing techniques on Mac so I can isolate AI tools and prevent them from interacting with files they shouldn't have access to -- like all my dotfiles, AWS credentials, and such. I've created two open-source solutions, one which uses a VM ( https://github.com/webcoyote/clodpod ) and another which creates a limited-user account with access to a shared directory ( https://github.com/webcoyote…

#364I've been working to build some tools for detecting and monitoring lookalike domains - the kinds of things used in phishing / brand impersonation attacks. My current prototype scans potential lookalikes for a target domain and then tracks DNS footprint over time. It's early, but functional - and makes it easier to understand if some lookalike domain is looking more "threat-y". I've also been working on automating the…
It would be interesting if it monitored ownership changes for expired domains.
There are several really good products in this space FYI, but a new angle I'm sure can be competitive.

#365A couple of months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?” Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?” Turns out not that hard. In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless…
agree.com is free though

#366This one's going to be out of left field, but last Thursday I launched Countdown Treasure ( https://countdowntreasure.com ) It's a real life treasure hunt in the Blue Ridge Mountains with a current total prize of $31,200+ in gold coins and a growing side pot. I modeled it off of last year's Project Skydrop ( https://projectskydrop.com ) which was in the Boston area. * Shrinking search area (today, Day 5, it will be 1…
love it, this is awesome!
did you do any math around predicting if 'donating' this gold to a treasure hunter would yield an even greater amount to hurricane relief?

lpviz is like Desmos, but for linear programming - I've implemented a few LP solvers in Typescript and hooked them up to a canvas so you can draw a feasible region, set an objective direction, and see how the algorithms work. And it all runs locally, in the browser!
If you go to https://lpviz.net/?demo it should show you a short tour of the features/how to use it.
It's by no means complete but I figured there may be some fellow optimization enthusiasts here who might be interested to take a look :) Super open to feedback, feature requests, comments!
For a 2-min intro to LP, I recommend https://www.youtube.com/watch?v=7ZjmPATPVzI

#368I am working on a infinite canvas for AI image/video/audio/3D generation. in other tools, its easy to create one off AI images/videos, but to create a cohesive story with consistent characters and locations is very difficult.

#369Continuing to work on a Low Power FM community radio station for the East San Fernando Valley of Los Angeles. We have started promoting and putting on local events and are trying to fund raise to build out the station. Raising money is hard! We did a big show in Burbank where several hundred people showed up but we only netted $800 after expenses. :( We were featured on our local NPR syndicate which is neat: https://…
This is sick - I happen to run a site for DIY and community organizations like yours. We have proven the best way to fundraise is to throw events like you did but to upsell people on a recurring donation when they get the ticket.
On the off chance you are throwing another event, I would love to help you raise much more than $800 one time (my site is https://withfriends.events/)

Thanks! Yeah, I unfortunately can't shell out a straight $20k donation, but I saved the $25k over the year from my e-commerce business and justified it as a marketing expense if worse case scenario happens and it's found earlier than the math predicts. But if we get past break even then can't wait to write that check to help out the communities around here that are still recovering.
