"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 organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun 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

One thing that has surprised me (and I should've known that it wasn't great at it), but it is terrible at creating bounding boxes around things it's not trained on (like bounding parts on a PCB schematic.)

Amazon ($2.3T)? Microsoft ($3.7T)? Meta ($1.8T)?
xrendan · 5 months ago
Amazon - Ecommerce (1994), AWS (2006)

Microsoft - Programming Language (1975), Operating Systems (1981), Office Suite (1983)

Meta - Facebook (2004), Instagram (2010)

I would argue microsoft is unique because of how badly IBM screwed up.

It gets slower as the instance gets faster? I'm looking at ops/sec and time/op. How am I misreading this?

I read that as the size of file it's transferring so each operation would be bigger and therefore slower

I have some really old code that pretty much does this, I'll see if I can find it.
xrendan · 7 months ago
Ugh, I don't have it. It was from before I used git.

Basically to do this you have a cups server that exposes itself as a network printer that prints to a specified PDF directory and then you have a program watching that directory for new files and if there's a new one it opens up whatever pdf viewer you want in full screen.

OT: someone please make a RPi image that "prints" a page to an eink display. I want to duct-tape an RPi Zero and a rechargeable battery to the back of a display, then be able to print recipes to it while cooking. Other people might print board-game rules or speech notes while rehearsing -- anything that you'd typically print and then throw away after brief usage.

I know I could make a PDF, sideload it to a Kindle, etc. Too many steps. I just want the display to appear as a printer on my phone.

xrendan commented on Launch HN: Bild AI (YC W25) – Understand Construction Blueprints Using AI    · Posted by u/rooppal

I love the Blueprint Understanding.

One thing I've been thinking about is if you could use a model like this as the first pass for permitters (Like a GitHub Actions CI/CD) who review blueprints.

Many developers use the regulatory side of various engineering approval processes as a quality control check which costs money and time for the regulator who is tasked with enforcing a standard.

It would also be good to speed up the workflow for developers saying hey, this thing looks weird did you really mean to do this?

And then further on, you could add a way to check it for constructability. My framer friends often get annoyed at whatever engineer because the way the structure is designed is materially inefficient or hard to construct.

> ~=$3400 per single task

report says it is $17 per task, and $6k for whole dataset of 400 tasks.

You're misreading it, there's two different runs, a low and a high compute run.

The number for the high-compute one is ~172x the first one according to the article so ~=$2900

It's weird that OpenAI has lower prices for same models and Azure has higher prices. Anyone can explain?

BTW impressive idea and upvoted on PH as well.

xrendan · a year ago
Azure charges differently based on deployment zone/latency guarantees, OpenAI doesn't let you pick your zone so it's equivalent to the Global Standard deployment (which is the same cost).

xrendan · 2 years ago
I'd be interested in knowing if anyone is seriously using the assistants API, it feels like such a lock in to OpenAIs platform when your can alternatively just use completions that are much more easily interchanged.
