I guess you already researched this topic: would laser turret work for killing mosquitos? And if no, why not? Seems more reliable.

why spend the scarce energy of the battery in addition what's already being spent spinning the propellers

I mean getting rid of drone, and having just laser turret.

I'm working on Paint Launcher (beta) – a minimalist Android home screen without icons, where you paint tappable zones onto your wallpaper instead. You can try it out now here: https://play.google.com/store/apps/details?id=com.lukew3.pai...

Very cool. I wish there more more customizable smartphone interfaces like this.

I’m working on https://tempmaildetector.com and more specifically a Wordpress plugin to support it: https://wordpress.org/plugins/temp-mail-detector-block-tempo... The plugin offers users a way to input their own block lists, a pre-existing one, or make use of the API which is constantly getting updated. As a first time Wordpress plugin developer, the approval process was a bit slow but it’s like that for a good reas…

As a frequent temp mail user (for privacy reasons) I wish these things didn't exist..

"One-time access links with no traceable sender" ... so people get anonymous messages while logged-in to this site? How does the sender know about the recipient in the first place? What would I put in my HN profile to get messages on the site? You have people's email addresses... isn't that a problem when saying "no traceable sender?" People will need anonymous email addresses. Why not have pass-phrase logins? I had…

Yea, the email part was a problem I mentioned in the white paper. Problem was I couldn't think of a way to enforce plan limits while making the subscription model work. If usernames, then they could just abuse it by creating new usernames each time. But I understand you. Maybe if you have some suggestions? So regarding the sender and recipient, let's say I wanted to send you something. A message or a file, but wanted…

Well, I've used paste bins before. How about one with an email address input that'll invite whoever is meant to view it?

So instead of sending someone an image in an email, you send them a ClosedLink, they can view it once, and you avoid having to send them the image as an attachment?

Some screenshots would be nice.

Have you ever wanted to write your life story but found it too overwhelming? I’m developing an app that acts as your personal interviewer, guiding you through your memories and helping you share them with your loved ones. The app is designed for older adults who enjoy reminiscing but struggle to organize their thoughts into a coherent narrative. The goal is to preserve their hard-won insights and pass them down—to fa…

Interesting! I built something similar at a hackathon a while back: https://fnands.com/blog/2024/factory-hackathon/

We called it Journalaist, and billed it as a personal ghostwriter. What we found is that it lives or dies by the quality of the interview

I've built a VST3 plug-in that simulates a Mesa Boogie Mark IIC+ preamp purely from the circuit.

The approach doesn't seem popular for professional plug-ins likely because it wasn't viable for real time until modern CPU enhancements became available. Performance scales with frequency of the input which is interesting and seems to be a consequence of using an iterative solver on a system of equations and using the previous sample's state vector as a guess for the current sample.

On my MacBook M3 it requires between 50 to 70% of a single core to produce a 2x oversampled output at 48000Hz. This can be scaled back by reducing the solution tolerance bounds and get down near 25% with minimal quality loss.

Working on https://ts.coach , a free guide to Typescript that runs entirely in the browser.

Menu is unclickable and Firefox shows "this page is slowing down firefox"

Thank you for the heads up - I made some poor React decisions when I was getting started for the sake of expediency, and now need to untangle them.

Are you expecting a lot of signups? As plan B, maybe aim to get a grant from the Oasis Protocol Foundation - they're all about privacy - and quiz them on what to do next.

My roommate and I are still working on Tornyol, our mosquito killing drone! It uses ultrasonic sonar to detect mosquitoes, and missile control theory to ram into mosquitoes and grind them in its propellers. Our target platform is a 40 grams tinywhoop so it’s safe to fly everywhere and makes almost no noise :). A Roomba for mosquitoes! The main plus compared to traditional systems is that a drone can cover an enormous…

The missile knows where it is...
