ozzydave··on Maybe you’re not trying
The original study was flawed I’m afraid https://news.ycombinator.com/item?id=41091803
ozzydave··on Discussion of the Benefits and Drawbacks of the Git Pre-Commit Hook
pre-commit hooks are awful, they get in the way of interactive rebasing. pre-push is where they belong; save a round-trip through CI.
ozzydave··on Show HN: AI Baby Monitor – local Video-LLM that beeps when safety rules break
I want this for pedestrians and cyclists at intersections, and particularly HAWK beacons.
ozzydave··on Ask HN: A question about mentoring a junior developer
I’d highly recommend looking up “Situational leadership” if you’re worried about coming off as micro-managing. You need to adapt how you’re mentoring based on the mentees skill and confidence.
ozzydave··on Why so few Matt Levines?
I’d say Matt O’Dowd of PBS Space Time is the closest to Levine’s role?
ozzydave··on How fast is quantum entanglement? Scientists investigate it at attosecond scale
Gotta love the confidence to casually think every physicist for the past 100 years is an idiot.
ozzydave··on How I animate 3Blue1Brown [video]
One of the best commencement speeches I’ve seen.
ozzydave··on Ask HN: What are you working on (September 2024)?
A couple of little Apple Watch apps - a drinks counter that calculates approx BAC, and a timer for stretching that gives a 5s pause between stretches.
ozzydave··on Tips for Building and Deploying Robots
Coupling / decoupling at high frequencies would be a challenge for sure - but seems achievable in a world of fully autonomous vehicles that can communicate.

I don’t think the second part (about length of the train) is accurate at all. Yes, a train made of pods roughly car sized would be longer, but only roughly 3x. If you look at the duty cycle of say BART rail, you could fit a lot more than 3x trains on it. The rail is empty most of the time.
ozzydave··on Show HN: I made a tiny camera with super long battery life
Oh wow! I’ve wanted this for ages, even started making it myself at some point!
ozzydave··on GPT-4o
Heh - I'm using ChatGPT for the same thing! Works 10X better than Rocket Money, which was supposed to be an improvement on Mint but meh.
ozzydave··on Don't bet on the joys of pokies (2011)
Blow up the pokies
ozzydave··on Electronic project kits: hands on with a vintage 160-in-1 (2016)
Look for an old Dick Smith kit?
ozzydave··on The Enchanting Blossom Explosion of Jacaranda Trees in Mexico City
In Brisbane, the Jacarandas in bloom meant it was exam time
ozzydave··on Why time seems to pass faster as we age
I journal ~daily since having kids. I feel the same way - it gives me peace knowing I can look back in time later and relive just a little what I was feeling today.
ozzydave··on Berkeley's upzoning would be among nation's largest
Unfortunately prop 13 broke that dynamic, among other ill effects.
ozzydave··on Berkeley's upzoning would be among nation's largest
I live on a street in Berkeley that was not red-lined, so it has single family homes and fourplexes. It’s great, we love it. You can choose to be miserable but it’s got nothing to do with whether your neighbors can afford a home.
ozzydave··on Duolingo Cuts 10% of Contractors as It Uses More AI to Create App Content
The first time I used DuoLingo, I was just trying to get through the tree, without really learning, and that was useless. Now I have a different technique: I’ll only listen (never read), and if I can’t comprehend and respond immediately, I’ll fail that exercise deliberately, so I’ll be re-tested later. For me, I only understand the language if I can understand some one speaking to me and respond in real time.
ozzydave··on Ask HN: Any felons successfully found IT work post-release?
Have you looked at Next Chapter at all? I know several folks who have come through and have amazing careers at tech firms: https://www.nextchapterproject.org/
ozzydave··on I want a city, not a museum
Building market rate housing lowers prices, as housing generally follows the demand-supply curve. https://www.lewis.ucla.edu/research/market-rate-development-...
ozzydave··on How many legs do ten elephants have, if two of them are legless?
I just tried with ChatGPT 3.5 & 4, they both got the correct answer…
ozzydave··on We used to build steel mills near cheap power. Now we build datacenters
Facebook built a datacenter in Luleå, near the arctic circle.
ozzydave··on Does Market Timing Work?
This data set should be expanded to include 100 of his peers who started trading at the same time.
ozzydave··on Salesforce is hiring over 3k people, despite axing 10% of staff
The data say wages have been outpacing inflation: https://x.com/JustinWolfers/status/1702134443203289513?s=20
ozzydave··on The inside story of Threads
I think the lesson is, avoid rewrites and don’t break apart your monorepo; have teams improve the platform while your product engineers go full-steam ahead. Compare with Twitter which spent 2 years in the woods rewriting to Java while FB kept growing, giant ball of PHP and all.
ozzydave··on Johnson and Johnson sues researchers who linked talc to cancer
OP is spinning this as an attempt by J&J to escape paying out the liability which it wasn’t - Matt Levine (of course!) explains the details here: https://www.bloomberg.com/opinion/articles/2023-01-31/matt-l...
ozzydave··on 'Incredibly noticeable': alcohol ban cut family violence, crime in Alice Springs
Alice Springs and the NT are too different from almost anywhere in the western world to translate this elsewhere. For example it’s 3 hours drive to the next settlement that might sell alcohol, which makes enforcement a different proposition.
ozzydave··on Anchor Brewing Company ends national distribution, kills Christmas Ale
Rings true to me. There’s better beer available at every corner store now.
ozzydave··on Mercedes beats Tesla to autonomous driving in California
Cities are much more energy efficient than anything else with the same standard of living.
