mnbbrown··on Don't add a read replica until you've read this
You guys sound like cool guys.
mnbbrown··on PgDog is funded and coming to a database near you
I've loved using pgdog for the last 6 months. It's been incredibly stable. It's nifty how they've solved the LISTEN/NOTIFY on a transaction pooler problem.

mnbbrown··on Cohere Transcribe: Speech Recognition
They are all transcribed by multiple blinded "accent natives". But yes, your point is valid - going to see if I can tease out the "single person accuracy".
mnbbrown··on Cohere Transcribe: Speech Recognition
Ran it over our internal dataset of ~250 recordings of people saying british postcodes (all kinds of accents, etc) - it's competitive for sure!

Soniox (stt-async-v4): 176/248 (71.0%) ElevenLabs (scribe_v2): 170/248 (68.5%) AssemblyAI (universal-3-pro): 166/248 (66.9%) Deepgram (nova-3): 158/248 (63.7%) AssemblyAI (universal-2): 148/248 (59.7%) Cohere (transcribe-03-2026): 148/248 (59.7%) Speechmatics (enhanced): 134/248 (54.0%)

P.s. how do I get this to render correctly on here?

mnbbrown··on Voxtral Transcribe 2
Incroyable! Competitive (if not better) than deepgram nova-3, and much better than assembly and elevenlabs in basically all cases on our internal streaming benchmarking.

The dataset is ~100 8kHz call recordings with gnarly UK accents (which I consider to be the final boss of english language ASR). It seems like it's SOTA.

Where it does fall down seems to be the latency distribution but I'm testing against the API. Running it locally will no doubt improve that?

mnbbrown··on Creating Bluey: Tales from the Art Director
As someone who’s from Brisbane but spent the last 7 years in London you’re 100% correct. Brisbane is the best city in the world. I’m excited to eventually move back.
mnbbrown··on Ask HN: What are you working on? (October 2024)
That’s cool!

Very familiar with BMSs but the lack of open standards and protocols has been extremely frustrating - makes me appreciate how good we have it with HTTP, etc.

Lots say they support BACnet but that’s only if they’ve been configured and the points exported, etc.

Haystack is a great step forward for labelling too but adoption seems fill with complexity :)

mnbbrown··on Ask HN: What Are You Working On? (October 2024)
Decarbonising buildings and massive warehouses..

It's a very fun mix of hardware (for data collection), and crazy SQL queries to model energy flows between buildings, solar, batteries, etc. Considering just one building is pretty easy:

consumption = imported - exported + generated - stored + dispatched. carbon = carbon intensity * imported cost = tariff * imported

but then you add a site with a couple of buildings, solar on one of them, grid limited exports, etc modelling these flows is challenging. Like consider the case where one building got 10% of it's imported power from another building's excess solar, then calculating carbon becomes more difficult.

and once you've figured all that - then you have to figure out what makes commercial sense to do next.. install a battery, expand solar, move onto a TOU tariff, do nothing - and that's a whole other world of optimisation problems.

mnbbrown··on Ask HN: What automation tools have you used to replace mundane activities?
Interested why you use the coldest colour for waking up? I do the same, but use a sunrise simulation instead that goes from warm to cold.

mnbbrown··on GPUs Are Now Available for Google Compute Engine and Cloud Machine Learning
Also interested in seeing what sort of failure rates you've had with GPUs. Our's have worked fine - but n=4.
mnbbrown··on GPUs Are Now Available for Google Compute Engine and Cloud Machine Learning
https://hub.docker.com/r/nvidia/cuda/

Edit: still requires nvidia-docker, or a hand crafted docker command that replicates nvidia-docker.

mnbbrown··on GPUs Are Now Available for Google Compute Engine and Cloud Machine Learning
A product like ours (ML based medtech) takes a lot longer than 6 months to validate - and we make extensive use of GPUs (both AWS and Google)
mnbbrown··on GPUs for Google Cloud Platform
Really? I was under the impression they just use standard compute instances to power Cloud ML?
mnbbrown··on Show HN: GUI for writing Elasticsearch queries
It looks very cool. That said, When I looked a couple of weeks ago SearchKit was not yet compatiable with React v15. It also manages its own state making it slightly more challenging to integrate with anything like Redux.

mnbbrown··on Install GPU TensorFlow from Sources with Ubuntu 16.04 and Cuda 8.0 RC
What sort of performance impact would Docker have in this situation? Any at all?

Edit: spelling

mnbbrown··on Ask HN: Building a Deep Learning Workstation: Intel Phi and New Pascal Titan X?
Did you ever anything back from the intel or nvidia guys?

This is really interesting stuff. How are you guys managing that scale of streaming data? Some kind of Kafka based stack?
mnbbrown··on Convert curl commands to Go code
There's no implicit comparison (if that's the CompSci name) in Go. You have to explicitly compare (!= is required)
mnbbrown··on Ask HN: Does anyone have an old computer laying around unused in Brisbane, AU?
Hey fellow Brisvegasian, my email is in my profile. Send me an email and I'll forward it around to all my mates. Maybe we can find something.

Excellent idea and such a simple execution.
