lukah··on Darktable
Thanks for the detail - it's really interesting to hear
lukah··on Darktable
Right?! And the rest of the README continues like that. Must be some juicy history here
lukah··on Darktable
I haven't heard of either, but have been hoping for a replacement for Aperture for years. Having no knowledge of the history here, reading the `ansel` github page sounds like the developer has some animosity towards `darktable`. Does anyone have any experience with both? Or more knowledge of the history here?
lukah··on OpenAI’s o1 correctly diagnosed 67% of ER patients vs. 50-55% by triage doctors
Exactly this. Most diagnosis isn’t about pinpointing the underlying exact cause, it’s ruling out the really bad stuff and minimising harm. Differential diagnosis just isn’t real world medicine.
lukah··on Jury told that Meta, Google 'engineered addiction' at landmark US trial
I'm not at all familiar with the American justice system, but would the fact that this case specifically describes the targeting of minors with such addictive tactics change things at all?
lukah··on Anthropic's original take home assignment open sourced
I've never heard AI-assisted coding referred to as "RalphWiggum"ing a problem, and now I will have to use that always. Thank you.
lukah··on Why proteins fold and how GPUs help us fold
I interpreted that section as alphafold not learning physics, but rather correlations within a constrained setting that a-priori correspond to physically sound inferences. It has a specific architecture that allows the model to make inferences that are more physically plausible than not, but not that it’s discovering actual, causally verifiable laws of nature (like what I’d assume are encoded into another non-ML approach to the folding problem for example).
lukah··on Transformers Without Normalization
From their implementation it looks like they’re calculating tanh and then applying a weight and bias
lukah··on Ocean Carbon Removal: Captura's marine carbon capture explained
It’s true that this could lead to unintended consequences as humanity is directly experimenting with a complex balanced natural system. But another perspective is that we have already done/are doing exactly that by pumping CO2 into the atmosphere at rates that wouldn’t have happened in nature. I know “two wrongs don’t make a right”, but it’s perhaps worth considering the price of course correcting our already hugely impactful behaviours, as the butterfly had flown years ago.
lukah··on Cybertruck's Many Recalls
Car panels are convex on nearly all other cars for very good reason. Flat panels are structurally susceptible to damages which wouldn’t mark a standard panel. Adding a highly reflective surface was another great move.
lukah··on The Power of Small Brain Networks
How do they track the brain activity of a fruit fly? That seems incredible to me
lukah··on Show HN: Using GPT-3 and Whisper to save doctors’ time
This is really interesting work, congratulations! A lot of negativity in the comments seems to stem from cynicism around doctors and their billing, but in a country like the UK I know removing essentially "admin tasks" from the GP would be very welcome and give time back to the clinician, allowing them to spend more time focussing on the patient and outcomes.
lukah··on Understanding and coding the self-attention mechanism of large language models
Great answer. Imbuing a deep learning model with well thought out inductive biases is one of the strongest ways of guiding your model to interpret the data the way you want it to. Otherwise it’s kind of shooting in the dark and hoping to get lucky.

I can’t stand it when people lazily personify ML models, but it’s akin to giving someone with no experience some wood and then pointing to a shed and saying “make one of those from this”. Instead you’d expect them to be much more successful if you also give them a saw, a drill, some screws etc.

lukah··on Aerodynamics of Gravel Bikes
If anything, you might be thankful of a full suspension mountain bike on some of our "gravel" trails in the UK. There's such a wide range from US-style back county roads all the way to bridleways with baby-head sized rocks that you probably wouldn't want to be riding on something typically sold as a gravel bike.
