mergisi··on Show HN: Rocky – Rust SQL engine with branches, replay, column lineage

mergisi··on Show HN: Pgsemantic – Point at your Postgres DB, get vector search instantly
The "zero-config" angle is strong here — the biggest friction with pgvector is the manual pipeline: choose an embedding model, write the chunking logic, create the index, tune the distance metric. Abstracting that into a single CLI command removes the part that stops most teams from even starting.

Question on the embedding side: are you generating embeddings at INSERT time via triggers, or is there a batch sync step? The trigger approach gives you real-time search but adds write latency. Batch sync is friendlier for high-throughput tables but means search results can lag behind.

Also curious how you handle schema evolution — if someone adds a new text column they want searchable, does pgsemantic pick that up automatically or require a re-config?

One pattern I've seen work well alongside semantic search: pairing it with natural language → SQL translation (tools like ai2sql.io do this) so users can combine structured filters with vector similarity in a single query. Something like "find invoices from Q1 similar to 'billing dispute'" where the date filter is SQL and the similarity part is pgvector. That hybrid query pattern is where most real-world use cases end up.

mergisi··on SQLite: Query Result Formatting in the CLI
The .mode options in SQLite's CLI are surprisingly comprehensive for what most people treat as a lightweight embedded database. Table mode and box mode in particular make ad-hoc queries readable without piping through external tools.

One underrated use case: switching between .mode json and .mode csv lets you prototype data pipelines entirely inside the SQLite shell. You can validate query logic, check edge cases in formatting, and export in the right shape without writing a single line of application code.

The challenge for newcomers is discoverability. Most people learn about .mode column and .headers on from Stack Overflow answers, then never explore further. Having the full formatting reference documented in one place helps bridge that gap — especially for people coming from tools like ai2sql.io (disclosure: I work on this) where the focus is getting the query right first, and formatting the output is a separate step they often haven't thought about yet.

mergisi··on GitHub cuts AI deals with Google, Anthropic
I understand your concerns, but I see a positive side to this evolution. While increased accessibility can lead to an influx of less polished code, it also brings diverse perspectives and innovations that might not have emerged otherwise. With AI, we have an opportunity to enhance productivity and assist developers in writing better code by automating routine tasks and catching errors early. If we focus on mentoring and setting strong standards, we can harness these tools to improve overall code quality rather than detract from it.
mergisi··on Computer use, a new Claude 3.5 Sonnet, and Claude 3.5 Haiku
My First Experience with Claude Computer Use - It's Mind-Blowing!

Just tested Claude's new Computer Use feature and had to share this simple but powerful test:

My Basic Prompt: "Please: 1. Search Amazon for 3 wireless earbuds: Find price Rating Brand name

2. Make a simple Excel file 'earbuds.xlsx': Put the information in a basic table Add colors to the headers Sort by price

3. Show me the results"

What blew my mind: - Claude actually looked at my screen - Moved the mouse by itself - Clicked buttons like a human - Created reports automatically

It's like having a virtual assistant that can really use your computer! No coding needed - just simple English instructions.

mergisi··on Ask HN: Which analytics platform do you use?
Consider Microsoft Clarity—it's free, offers session recordings, heatmaps, and detailed insights. It's easy to integrate with Vercel, and unlike usage-based platforms, has no hidden costs. A good alternative if you want more than basic analytics.

mergisi··on Ask HN: What to do about startup job
Since immigration sponsorship is crucial, it’s wise to stay while passively exploring new opportunities and networking. Focus on upskilling or working on side projects to keep yourself prepared for future moves. If the current role isn’t providing value, think about how it can still support your long-term goals.

more options for customizable tuning would be great.
mergisi··on Shape the Future of AI: Llama Users, We Need Your Feedback at Meta!
I tested Llama 3.2 on my MacBook, and it runs impressively fast. I plan to look more deeply into its capabilities and have some specific use cases in mind for further testing. Fine-tuning could be improved, and better integration with AI stacks like RAG would be helpful. Overall, it's a solid model with great potential! https://x.com/mustafaergisi/status/1839647877498278311
mergisi··on Ask HN: What's the Alternative to Agile?
An alternative to Agile is Deep Work, which focuses on uninterrupted time for focused problem-solving instead of frequent meetings and updates. While Agile promotes quick iterations, Deep Work emphasizes sustained concentration, allowing teams to tackle complex tasks without distractions. It’s not a framework, but a focus-oriented approach that could complement or enhance existing workflows.

mergisi··on Ask HN: Are you making money from LLMs? How?
I totally get that feeling! AI tools like ChatGPT can be great for basic code generation, but they still have limitations when it comes to complex or highly customized outputs, like your menu. That’s why tools fine-tuned for specific tasks, like AI2SQL for database queries, can be more reliable in those areas. As AI continues to evolve, I'm hopeful we’ll see improvements that bridge these gaps for more complex coding tasks like JS, CSS, and HTML.
mergisi··on Ask HN: Are you making money from LLMs? How?
Thanks for the feedback! Aside from SQL query generation, we're exploring ideas like automating data transformation tasks or simplifying API integrations using GPT. There’s a lot of potential for solving niche problems like these. I'd love to hear any ideas you have!
mergisi··on Ask HN: What are your use cases for o1 so far?
I’ve been experimenting with o1 as well, and while it hasn’t radically changed my workflows, I did use it to create a blog webpage with minimum human effort required. It helped automate much of the content creation process, reducing the need for constant oversight.
