"Google maps but for old maps": https://pastmaps.com This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS . It gets ~80K MAUs and just slowly and consistently is growing o…

Hey, cool to see! I'm running a similar but smaller project (5k MAU), my oldest map is central London in 1561 https://onamap.me/maps/London1561/ I got into it because I was interested in the technical challenge of registering GPS to maps which are very warped compared to reality, like very old maps or illustrated tourist maps. My home page is here for more: https://onamap.me/ I also came across this similar project a…

whoa this is wickedly cool! and yes, georeferencing these old maps is the bane of my existence right now

awesome project

I would absolutely love if you brought Canadian maps to this. I work for Build Canada and I would love to see some maps from the fur trade and early exploration to tell stories. If you want to chat my email is brendan at buildcanada.com

Hey Brendan! I also would love to add Canadian maps, it's been a huge request from my users and something I've been wanting to focus on all year. A big challenge I have in bringing the service to new regions is just data access, both to raw hi-res map imagery as well as to satellite, LiDAR, etc so this is on my todo list to begin digging into what the Canadian government offers. Brave new world for me

Will absolutely reach out to connect!

Awesome work. Just out of curiosity, where do you source the maps from? In france IGN has a ton of old maps

Around 90% of the maps currently on the site are from the US government (USGS). The last 10% are from public institutions and libraries and this is the newest segment that I'm actively working on growing. My hope is to flip this ratio with time.

I also have a few partnerships in the work with some private collections but those have proven trickier to actually get to a "yes". It also involves a lot of bespoke work to process and ingest each individual source so I'm not focusing as hard on this type of sourcing anymore.

Building an app to help me stay in touch with my friends (https://wavepal.app).

I have ADHD and often forget to reach out to important people in my life, not because I don’t care but because “out of sight, out of mind” is EXTREMELY true for my brain.

I started building Wavepal with a friend earlier this year so I can track when I last chatted with people, what we talked about, important details that I’m likely to forget (kids names, important dates), and it auto sends me reminders when enough time has passed since we last talked.

I'm working on a new unconventional form of computing called "temporal computing" - as both a PhD and as a fledgling business. The idea is to use delays in time (It's called interval modulation) as the data. I have a video explainer on YouTube https://youtu.be/rXbzJxThgig?si=FYMleAgZ0GMNEqk9 . It's a long road building your own computational model and I'm currently looking at Turing completeness, and models of multip…

Well, that's certainly an interesting way to save energy in a logic circuit. The problem I see is that you're going to be able to have to save the value in an analog form at some point to do anything other that single bit math.

Perhaps looking at using each transition in a circuit as a bit, instead of level, could be useful as a power saving strategy that could be compatible with existing VLSI fabrication?

Sprouts/Gardener: a project to make self-hosting possible (and easy) without linux sysadmin skills

https://judi.systems/sprouts/

Current version focuses on static site hosting, with templates and zero-config localhost preview, one button to publish changes live.

Part of making this project involves creating a GUI framework for Go

https://judi.systems/slay/

Using flexbox-like layout system, it can render UIs for desktop apps in pure go (without using html/js/css).

We're building Parsnip (https://parsnip.ai/), a "Duolingo for cooking" with a personalized learning platform powering it: https://parsnip.substack.com/p/vision-part-two.

We're also hiring a product designer to work on our AI learning platform; if you know anyone good we'd love to meet them! https://parsnips.notion.site/product-designer

Earlier quoted context omitted.

Do I understand correctly that in order to pay someone through your service I need to first create an account and then link it to a conventional card? If so, it's ultimately a PayPal remake?

> ultimately a PayPal remake? Pretty sure you can't send tiny fractions of a penny through PayPal.

you could using gripto

Still working on cataloging a curated list of craft beer venues across the world at https://wheretodrink.beer Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep adding things. Next addition will be to add health inspection data from countries that have that in open datasets or APIs, so if anyone know of that I'd be appreciative of…

Just checked out NYC and saw that most of the venues have abysmal ratings (e.g. 3.02/10). Am I reading the numbers wrong?
