arsalanbon Show HN: Artie – Real-time data replication to your warehouse, now self-serve

Congrats on the launch! Very impressive product!

arsalanbon NanoClaw moved from Apple Containers to Docker

I'm surprised that the developer experience around sandboxing on macOS is generally so bad. Seatbelt is in limbo and apple containers are just a pain to work with as some have highlighted in this thread

arsalanbon Railway (PaaS) global outage

I will charge you $100 to answer that question

arsalanbon Railway (PaaS) global outage

We weren’t affected, but as a startup I’ll take a minor outage over getting stonewalled by GCP/Azure/AWS any day. Railway has consistently been responsive and actually understands the problem you’re describing. With the big three, unless you’re spending serious money or paying for premium support, you often just get links to docs instead of real help.

arsalanbon Launch HN: Livedocs (YC W22) – An AI-native notebook for data analysis

We include $5 in credits for every new account, after which you can pay-as-you-go for credits. I can drop some more credits in your account so you get to try it out fully, let me know what's the email (I'm a at livedocs)

arsalanbon Launch HN: Livedocs (YC W22) – An AI-native notebook for data analysis

Livedocs runs locally on your machine or on customer-managed infra, has full terminal access, supports canvas mode for building custom UIs (not just charts), and uses long-running agent workflows with sub-agents coordinating work over time, etc

There is a lot more to data work than just SQL + charts like the tool you mentioned

arsalanbon Launch HN: Livedocs (YC W22) – An AI-native notebook for data analysis

True! Tried to do that with the video + the example prompts but definitely could use improvement. Thanks for the feedback

arsalanbon Launch HN: Livedocs (YC W22) – An AI-native notebook for data analysis

In our case, in order to run the queries we need to provision a sandbox and connect to your data sources to give meaningful answers, unlike a general purpose chat. We need to have some authentication to prevent abuse here, but the product itself has a free tier so you can use it without paying or needing a card.

arsalanbon Ask HN: What are you working on? (July 2025)

Working on Livedocs.com

We are building a modern alternative to Jupyter, something like Cursor meets Jupyter.

arsalanbon Ask HN: What are you working on? (May 2025)

https://livedocs.com

An AI data scientist for serious data work. Think of it like an AI native Jupyter notebook.

arsalanbon Instant SQL for results as you type in DuckDB UI

Check out livedocs.com, we built a notebook around Polars and DuckDB (disclaimer: I'm the founder)

arsalanbon Apache ECharts

We use Vega pretty heavily, its a broader ecosystem. Where it really shines is in combination with Altair and Vegafusion to do number-crunching on the backend and return a chart spec that can just be rendered on the front-end.

That makes it particularly useful when building interactive visualizations with a lot of data.

arsalanbon Show HN: Stempad – Fast Online Scientific Writing

Is the Python code executing via Pyodide in the browser?

arsalanbon Show HN: 10 Years to Build a Free SQL Editor

Out of curiosity, what took you 10 years? Keen to hear your journey as someone building in the same space..

arsalanbon Show HN: Peerdb Streams – Simple, native Postgres change data capture

I see, thanks!

arsalanbon Show HN: Peerdb Streams – Simple, native Postgres change data capture

Assuming you use a connection pool, why would it stop? Either the query returns a result or it doesnt? Am I missing something?

arsalanbon Show HN: Peerdb Streams – Simple, native Postgres change data capture

Noob question: What is the advantage of replicating data into a warehouse vs. just querying it in place on a postgres database?

arsalanbon Show HN: Timefinder – a simple way to find a team to chat across timezones

That sounds like a great add! Will add this in over the weekend!

arsalanbon Show HN: Easily Visualize Your SQLAlchemy Data Models in a Nice SVG Diagram

This is great, especially to introduce new devs to models. I use (and love) TablePlus (https://tableplus.com/) which has a diagram generator plugin that does the same!

arsalanbon French startup unveils new residential thermo-acoustic heat pump

I imagine this is possible because of better modulation of the acoustic and pressure controllers to minimize energy loss..

arsalanbon French startup unveils new residential thermo-acoustic heat pump

Probably not. A similar acoustic heat pump company (https://www.blueheartenergy.com/ourtechnology) claims 30 db, so this is probably going to be in the ball park.

It uses the acoustic wave to expand and contract pressurized helium, and then conduct heat created from the subsequent pressure oscillation.

arsalanbon Thank You HN

@dang is truly a legend. Shared some thoughts with him about an idea I had and feedback was truly insightful. Massive hat-tip to the legend!

arsalanbon Show HN: Search Domain and Username in the same place

Chiming in here — not sure about this. I checked for a name that showed as "available" on the link above. I requested the owner of that Github handle a year ago if they were willing to release it to me, as they have zero public repos on there. Long story short, they didn't.

No chance that Github will take the handle off them and give it to us too.

My point is, this is definitely a bug, since the above account is not a ghost account.
