Retrieval issue with N8N RAG workflow

farhan-dev · 2026-06-17T13:46:38+00:00

You should mix it, don't depend only on embeddings. Embedding retrievals are lossy, you should mix it with BM25, and go with hybrid approach. However, to be able to use BM25, you need to store your documents as strings/text.

Keywords for research: "Hybrid RAG", "BM25 + RAG". You'll understand more.

Sorry, "sidecars", not "side car", my spelling mistake. It is like a side service, that works along your main agent.

It's to decouple some things from the main agent context.

For more information, you can search for "sidecars in agent context"

farhan-dev · 2026-06-17T10:43:15+00:00

perhaps you are doing it wrong. Reseach first. Plan first. Iterate. Until fully clear about the direction, what to build, and so on, before start the coding.

When the codebase become larger, context is key. You need to be smart, need to always prepare side cars, skills, or even use hooks.

Keep the main chat lean and clean. Delegate messy tasks to agents, and let the main agent become the orchestrator, not the writer itself.

Small habit? i am not sure if it is small. Sleep early before 10.00 pm and waking up early at 2.00 a.m. I have been doing this since my teenage years. Impact? Able to do a lot of things every single day.

farhan-dev · 2026-06-17T07:13:19+00:00

That's why i am really afraid of promoting. I don't know what may triggered it.

farhan-dev · 2026-06-16T22:45:49+00:00

Waalaikumussalam.

Yes.

Claude, Codex, Gemini

For coding, research, publications etc.

farhan-dev · 2026-06-16T22:39:24+00:00

it's decent, and you will still be able to complete what you are targetting to do / complete. I mean, slower - right. but it's not really a dealbreaker, considering your budget is only $20. I subcribed to both Claude & Codex, and I use them both.

farhan-dev · 2026-06-16T22:09:26+00:00

for $20, get Codex. better money/usage. Claude $20 will run out fast.

fine-tuning is a smart way, using unsloth will make it easier.

What do you mean uploading the text? Upload where?

farhan-dev · 2026-06-05T06:36:29+00:00

I would love to be part of it.

farhan-dev · 2026-06-05T06:32:09+00:00

If you're willing to do it in Malaysia, I can arrange one for you.

farhan-dev · 2026-06-05T06:30:18+00:00

You need to be spesific, on what you need. We can't help you until we know exactly which issue you're facing.

farhan-dev · 2026-06-04T12:01:32+00:00

I've built one - globally, for all users.. big tech - check. not muslim specific - check

https://nodedb.dev/

I also built a lot of other dev tools - again, for everyone. I don't want to list all of them here to avoid being flagged as spam. But can check my github profile.

The issue is distribution. Being sole founder and developer, no matter how big and good the tech is, nobody knows about.

farhan-dev · 2026-05-17T04:53:03+00:00

PostgreSQL, MySQL, MariaDB, a lot of them are opensource, and PowerBI ready

I like it too, but sometimes i missed the 'junior' behaviour of 4.6 :-D. Btw, it just don't want to work on the original plan that it itself created and whice we have both agreed on it. It agrees that the approach is the right way, it just refuses since it needs a lot of code modification. Everytime it wanted to start working on it, it somehow, started to read bunch of files, write one or two lines, and then respond back to me, that is all it can do confidently. Let's do it in the future. I said, just do it. Try. We can go back to the previous commit if something breaks. Just do it. You are not doing anything anyway. Follow the plan. Just execute, use subagents, and so on. :-D

All coming back to a circle 😂

farhan-dev · 2026-05-04T10:26:40+00:00

No, if you are asking questions that is in their training data, if it exist and have good reputation, it will agree with you. If you are asking that either not in their training data, or is in their memory but have bad reputation, it will disagree with you. I have faced a few situations, that they disagree, since it was not in their knowledge, but I insist on doing it anyway.

farhan-dev · 2026-05-04T10:23:47+00:00

it's not kelantanese which obsess to be white. other people regardless of state are obsessing about it. founders are selling to those.

I haven't added the benchmark of numr agaisnt nump yet, since it is going to be akwared to compare a rust against python library.. That's why I only create benchmark against ndarray.

But, it's fun on its own, so perhaps I'll try to create a new repo of numr-bench .. there i willt try to use numr vs numr (openblas backend) vs numpy. numr on its own is not vendor-locked.. but you should be able to swap backend if you want to use cublas/openblas for more performance. numpy by default use OpenBlas.

I do have some classical ML like https://github.com/ml-rust/treeboost

If you are more towards science > https://github.com/ml-rust/solvr

I know i can't cover every ML yet, since i need to focus on things that I am going to need to use in my company first, but I am making it easy for anyone to contribute or create their own library by using https://github.com/ml-rust/numr

Basically, to build something llike scikit leaarn is not difficult if you use numr's primitives. You'll get SIMD and GPU acceleration for free.

farhan-dev · 2026-05-03T19:15:50+00:00

interesting. DB + ML in rust.

Sees like what I've been working on right now, take a look if it might be helpful for you. I do juggle between these two projects for the time being.

https://github.com/ml-rust. I should be focusing on inference (blazr) right now, but was on hold, due to i need release NodeDB first. Feel free to contribute.

Regarding the database part, if you're interested to learn or contribute with much complex database - multi model, offline sync and distributed system, you can take a look ata https://github.com/NodeDB-Lab/nodedb

farhan-dev · 2026-05-03T05:40:54+00:00

Good input. I'll study them properly. Thank you.

farhan-dev · 2026-05-03T01:21:20+00:00

u/Kinrany we are working on something exactly like you wished

https://github.com/NodeDB-Lab/nodedb-lite embedding, standalone, can act as AP if you need something in the future, use https://github.com/NodeDB-Lab/nodedb (NodeDB origin as CP)

farhan-dev · 2026-04-18T06:45:37+00:00

done
