The tele-op stuff is very interesting. Are there off the shelf SDKs for this type of thing or do you need to build it yourself?

o1-pro understands JS proxies better than me tbh, so probably a positive acknowledgment.

The API is basically the prompt LOL. I chucked in the API, and had o1-pro write tests + fix bugs until it worked.

Yes that is exactly what it is! It's basically a very small upgrade over my favorite database: A JSON-file :)

dang -- why was this flagged? Seems like a perfectly reasonable post.
Re:Show HN: NoSQL, but it's SQLite on Sunday December 22, 2024 @12:12PM (#42487656)
The implementation is very clearly included, if you... scrolled down.

And the point is, you could easy do `const db = new Database("./database.sqlite")` instead.

The wrapper makes it so manipulating your database is just like manipulating a plain Javascript object.

Ask HN: Has anyone used Devin for web-dev?

I'm thinking of purchasing the Devin subscription, so I can give it screenshots of a web-app, and have it just implement the flows. But ... I don't know if it will be capable of doing so.Has anyone used Devin for this type of thing?

Follow-up question is: Isn't it extremely unlikely to output 0?
Re:Differential Transformer on Tuesday October 08, 2024 @10:43AM (#41777898)
Is the thing that's going on here that softmax can't push a value to 0, but by subtracting 2 softmax maps we can output 0s?
Re:Ask HN: How do I profile my Postgres database? on Sunday September 24, 2023 @05:37PM (#37637443)
Thanks for the help, I'll try these things out. Is this knowledge you picked up through experience, or is there some comprehensive set of tutorials on scaling / profiling Postgres?

Ask HN: How do I profile my Postgres database?

I am running a t3.micro instance -- and doing about 8 queries / second. Not many, but it seems like queries are consistently taking 1-10 seconds to respond, and as a result, the site is going down.I'm having a hard time telling what the problem is. Are some of my queries really slow and inefficiently designed? Is is it just that my database is too small and I need to upgrade it?Is there...

Re:Ask HN: What is the correct way to deal with pipelines? on Friday September 22, 2023 @01:31PM (#37614963)
It seems like the modern solution is to use something like temporal.io -- (related to windmill). Alas, surely people have been solving this problem for ages now without temporal.io

Ask HN: What is the correct way to deal with pipelines?

I have an application where once a job succeeds it needs to go through a series of steps, some are CPU intensive (ffmpeg, etc.), others require communicating with an external API that may fail (Discord), etc.This is not a massive data-engineering project. I just need to ensure the steps get run to completion.My current plan to do this is to just use Redis lists as queues, and then have steps go...

Ask HN: How do I write a good request-for-feedback email to my users?

I have a project with some users, and I'm trying to determine the root cause of churn. I've been sending the following email to my users to get feedback, but I'm not sure if it's any good. Does anyone here who is more experienced have suggestions on what I should do?Hi,I'm X--the guy behind Y. I'm trying to improve the product, and I'd love to chat with you about your experience using it....

Ask HN: What is the simple way to ensure internal services stay up?

My server runs a core loop that must do an iteration at least once a minute. If it fails to do an iteration, I should be notified.What's the easiest way to do this? Seems like I can either: 1. ping a service like healthchecks.io at the start of a loop or 2. expose some HTTP endpoint indicating whether the loop is running on timeNot sure if both are equivalent

Ask HN: What is an simple logging aggregator?

I'm running a NodeJS server that currently prints nice logs to the console using the `debug` package. As the server gets more busy, I would like to print my logs as pretty graphs (N users on the platform at Y time, etc.)It seems like the correct thing to use is Grafana + Loki, or something like the elastic stack. But these are far too heavyweight. Is there some dead simple solution I can use to...

Ask HN: Has anyone else had trouble with Cloudflare R2?

Last ditch tech support question, but was wondering if anyone else has run into the following issue with R2: When transferring a moderate amount of files (~ 50+), the last file often takes a very long time to transfer, even though it seems like it has fully transferred.For example, here's the rclone output: Transferred: 146.271M / 146.271 MBytes, 100%, 2.600 MBytes/s, ETA 0s ...

Ask HN: Best back end framework to pair with NextJS?

I like Next.JS. It makes frontend development very easy. But, there are still too many decisions to make for the backend. What database to use, what to use for authentication, etc.What is the best framework for quickly spinning up APIs with all-batteries-included (no decisions to make). Is it rails, or something else?

Ask HN: Simple Logging / Stats Solution?

I have a bunch of side projects running on platforms like Heroku/fly.io/etc. They are usually NodeJS.I want a very simple logging solution (since platforms like fly.io do not retain logs). Think, logging K/V pairs from NodeJS that get streamed to some server.Ideally, the logging solution would be something simple I can spin up in a Dockerfile on fly.io--but I'm also open to using hosted...
