This technology has implications in AR/VR world, as well as in historical preservation of monuments and sites by creating their digital twin. Play around this on your phone or browser: splats.earthbytelab.com/hickorywood/

Is this a drone footage? No! It a #DigitalTwin of Hickorywood park, a 3D world reconstructed by using #GaussianSplats using some fancy #AI technologies developed in collaboration with @earthbytelab.bsky.social It's now a world with colliders that one can walk through like a video game.

One of the reasons I cancelled my Oura membership is the cloud dependency, someone deciphered the BLE protocol: github.com/Th0rgal/open... My past weekend project: based on this protocol, I was able to build a macOS app that does data ingestion locally from my Oura ring... on to some ML training!

Two weeks of math optimization & 10min 360 camera drone footage orbiting my house: an amazing “Gaussian Splat” of my house! Unfortunately I won’t be sharing the ply file to play with for privacy reasons, but definite progress. Now will add LiDAR data, remove sky from input & look for improvement.

TLDR - Python is great for prototyping the math for validation. Move to go/c/c++/rust to speed up real-time on-the-fly calculations. All these can be encapsulated as binaries that can use Python as a wrapper.

I read a bunch of papers on a math calculation for one of my sensors, loved to combine all of them. Claude systematically combined in python (in 5 days) after breaking down the problems into smaller chunks. Then we spent 8 hours rewriting the implementation in rust & used gpu cores to speed up 20x!

Voice-in voice-out: ~2m47s 😂 first turn (STT 6s + 60s prefill + 30s gen + TTS 1s). Pascal's no-tensor-cores prefill on a 16K system prompt is the bottleneck. Subsequent turns hit llama-server's prompt cache → ~30s/reply. Ampere+ would cut prefill 6x

Gemma 4 E4B is amazing for its size, I’m waiting for upstream MTP merge to see how much I can push in this oldish hardware.

Built a fully-local OpenClaw AI assistant available on WhatsApp using CachyOS (Linux) box w/ an old GTX 1070 Ti (Pascal, Vulkan). Orchestration Stack: - Gemma 4 E4B for chat+vision+STT - Piper for TTS - DreamShaper 8 for image gen Voice-in/voice-out, photo descriptions, image gen: zero cloud calls.

Someone mentioned two words “Gaussian Splat” on Friday and I went into a deep rabbit hole into this wonderful technology. Went through a bunch of papers, math/reconstruction and free open source programs. Going to try some point cloud reconstruction soon.

mqtt2db-go v0.1.1 - addressed realistic scenarios Sustained PG slowdown stress test (toxiproxy, 10K msg/s): • moderate +300ms: drain 18s • severe +2.5s: drain 20m • outage TCP-rej: drain 8m 6/6 PASS, zero DLQ, exact conservation. Per-conn cached staging + parallel flushers: 5K → 25K rows/sec.

Deb Sahu @debashishsahu.com · 01/05/2026

Both fair. Stress schema was minimal (one table, unique index on dedup_key only); wider schemas with secondary indexes hit a different ceiling. And agreed: 30s clean runs prove little. Real next test is sustained PG slowdown to exercise adaptive flusher mode transitions and WAL spill. Honest gap.

Deb Sahu @debashishsahu.com · 01/05/2026

mqtt2db-go is the middle ground: a focused Go binary that does one thing well. Subscribe to Comqtt via shared subs, batch via pgx.CopyFrom into Postgres, with operational properties tuned for IoT telemetry at scale. No broker coupling, no schema rigidity, no licensing surprises.

000

Deb Sahu @debashishsahu.com · 01/05/2026

Why this exists: moving MQTT into Postgres has two off-the-shelf paths, and both have tradeoffs. EMQX bundles a rule engine with DB sinks but couples ingest to the broker hot path and now carries BSL licensing risk. Telegraf and NiFi work but offer little control over backpressure.

100

Deb Sahu @debashishsahu.com · 01/05/2026

Key call: the durability boundary lives at Postgres, not the WAL. MQTT messages get ack’d only after successful insert, so the at-least-once contract holds end-to-end. Throughput is bounded by COPY rate; the win is clean failure semantics. Badger smooths bursts, S3 catches poison.

000

Deb Sahu @debashishsahu.com · 01/05/2026

Architecture: Comqtt (Apache 2.0 MQTT broker) feeds mqtt2db-go, which batches via pgx.CopyFrom through PgBouncer into Postgres. Three-tier buffer absorbs bursts: in-memory ring, Badger WAL on PVC, S3 dead-letter. Ingestion decoupled from processing; backpressure propagates upward.

Qwen 3.6 27B (tiny model) beats opus 4.5 and can run locally on a 64GB MacBook Pro - excellent for agentic coding tasks. I’m genuinely impressed for its size huggingface.co/unsloth/Qwen...

Ohh no, another one I will be skipping. Feels like they ask for feedback - we all say that infra at Asilomar is dated and it’s just ignored. Love the people, community and science - don’t love the conference grounds.

Hopefully it’s not in ASILOMAR! What’s the location?

Never meant for consumer use, usually these are flashed with openwrt or something equivalent. That’s what these are used for. That being said most routers have backdoor for recovery mode, where one can do firmware dump or even flash with custom firmware.

No need to hack it, leverage the open source community. All of prusa design, electronics and software is free!

Amazing videos… side note I’ve personally used that Magritek’s earth field NMR in the background of these videos. It’s really cool to understand basic NMR/MRI concepts. However, it took me a week to figure out why I wasn’t getting any signal because the building I was in was a Faraday cage!
