choilive··on Apple's Software Quality Crisis
If Spotify doesnt work they are dead in the water. If Apple Music doesnt work, thats a rounding error.
choilive··on Resident physicians' exam scores tied to patient survival
But now you have the problem of being too specialized - Ive seen many specialists that think a problem lies within their specialty- when it does not. And how do you deal with problems that are multi-disciplinary (problems that require multiple organ systems) when you have an army of specialists that are each fighting for their own fiefdoms? When all you have is a hammer everything looks like a nail. Comes to mind.
choilive··on The Great Re-shard: adding Postgres capacity (again) with zero downtime (2023)
Oh nice. I had dismissed offline/local web apps for anything decently complex for a long time because of the file system limitations. But it looks like this will finally make that practical with OPFS & WASM SQlite. Thanks for sharing.
choilive··on AMD Radeon RX 9070 Series Technical Deep Dive
Would have liked to see 24gb of vRAM in this segment, although that was probably reserved for the cancelled higher tier cards.

> Ultimately I’d prefer to serve every read from your device’s local storage, which is my current project.

Is that for native desktop/mobile clients only or web as well?

choilive··on Amazon now discloses you're buying a license to view Kindle eBooks
Doesnt directly answer the question, but nowadays there are good and free TTS that will essentially turn your entire ebook to an audiobook. (Elevenlabs Reader for example)
choilive··on Mexico issues legal threat to Google
But wasn't that the tariffs? How would changing the name give any leverage?
choilive··on Mexico issues legal threat to Google
What leverage did he gain exactly?
choilive··on Show HN: Subtrace – Wireshark for Docker Containers
Always wanted a tool like this. Will try it out next time I need to inspect traffic of a docker container.
choilive··on Why can't we remember our lives as babies or toddlers?
Since LLMs/AI are all the rage these days - I also found a similar behavior with LLMs.

If I ask a difficult recall question (usually some very niche medical knowledge) it will get it wrong or just hallucinate. But if I ask it in the form of a multiple choice question, it often gets it right. If memory works better when prompted with the information this way - I wonder how similar LLMs and humans actually encode memory?

choilive··on Nvidia's RTX 5090 power connectors are melting
I would bet a lot of money more than 1 engineer at nvda flagged this as a potential issue. If you were going to run this close to the safety margin, I would at minimum add current sensing on each pin.
choilive··on Cheap solar power is sending electrical grids into a death spiral
No need to break them up, just ship them to the universe's most efficient storage mechanism - a black hole!
choilive··on Cheap solar power is sending electrical grids into a death spiral
Industrial power consumers are billed differently - so it could be more or could be less. The bills are more complicated - industrial customers will generally pay for things like power factor, capacity, demand, time-of-use rates, tiered rates, etc. On a per kWh basis it would depend from customer to customer. If you had a factory that operated overnight for whatever reason, their electricity would be very cheap.
choilive··on Zed now predicts your next edit with Zeta, our new open model
You can turn all of the AI features off via the settings.
choilive··on DA, sheriff, who shared woman's nude photos on phone are covered by QI
Simple, but hard to push through. The often politically powerful police don't want that to happen.
choilive··on Zed now predicts your next edit with Zeta, our new open model
I don't think this is a concern. Zed and Zeta are both open source. Fork it, self host it, whatever.
choilive··on I built an open source AI tool to find my autoimmune disease
This is why proper differential diagnosis skills is important - something a layman would not understand. You must consider ALL possible conditions that your symptoms match, and then work your way from the most common to the most unlikely. AI is remarkably pretty decent at doing DDX.
choilive··on Three Observations
Biological neurons != artificial neurons. You don't need to simulate biology to simulate intelligence. In the same way you don't need to flap wings to fly, or muscle fibers to move around.
choilive··on Three Observations
You could also make an argument that the bulk of college degrees are not economically useful. The demand for certain kinds of education and knowledge is certainly finite - but the demand ceiling for general intelligence seems much much higher, and appears to be limited only by the cost of hiring ever smarter people.
choilive··on Three Observations
The costs are coming down fast because of the investment and would not happen independently of the investment. The same reason for Moore's law can be generalized as the learning/experience curve. You could make the argument that the demand for AI has a higher growth rate than the learning rate ex. if AI becomes 10x more cost efficient and results in demand growing 100x, you would also need to follow with an exponential growth in inference investment.
choilive··on The origins of 60-Hz as a power frequency (1997)
Yes, but not just electric cars. Theres a push to move the entire electrical system of all cars from 12V to 48V to reduce the amount of low gauge wiring in a vehicle
choilive··on The origins of 60-Hz as a power frequency (1997)
The skin effect is an important difference (and advantage in favor of HVDC) so it is in fact a concern of AC vs DC.
choilive··on Search PPP Loans by Zip Code
gotta upgrade your tinybird plan ;)
choilive··on Escaping surprise bills and over-engineered messes: Why I left AWS
Been using OVH for bare metal for a few years now and no major hiccups other than scheduled maintenance.
choilive··on Open-R1: an open reproduction of DeepSeek-R1
deepseek claims they are "open source" but they are not. They are open weight.

IMO a truly "open" AI model should have 3 components publicly available: the weights, the code, and the dataset.

Without all 3 the model is not reproducible. Could make the argument that the code and data are sufficient though.

choilive··on The Mythical IO-Bound Rails App
Rails also has an application level connection pool for the database but as I understand a connection pooler (pgbouncer et al) between PG and the application servers is still necessary when horizontally scaling.
choilive··on Why OpenAI's $157B valuation misreads AI's future (Oct 2024)
I wish this whole internet fad would just die already!
choilive··on Show HN: Using YOLO to Detect Office Chairs in 40M Hotel Photos
Depends on where you're looking.

There are usually plenty of "business" oriented hotels near airports, business parks, central business districts, convention centers, etc . (And that definitely reflects on the trip office map). Touristy areas have more tourist/traveller oriented amenities.

choilive··on Calm tech certification "rewards" less distracting tech
You know whats calm and not distracting? A notebook and pen. You can buy a LOT of decent notebooks for the price of one of the reMarkables mentioned in the article. (~30 or so?), and it will last a lot longer as well. Im starting to sound like a luddite.
choilive··on Lightcell: An engine that uses light to make electricity
The innovation here is you have a system that emits monochromatic light, and you have solar cells tuned specifically for that bandgap, plus the system is also "naturally" concentrating because the light output is incredibly bright. 3000 suns vs 500-1000 suns in typical CPV, plus they also do waste heat recycling. End-to-end efficiency of 40% is definitely feasible as advertised.
