tanvach··on One way to fight loneliness: Germans call it a Stammtisch
I’m getting from the article that you can get invited to these as well as keeping existing friendship going.
tanvach··on Show HN: Bluetooth USB Peripheral Relay – Bridge Bluetooth Devices to USB
This is very cool. I have a Kinesis Freestyle2 Blue for Mac that keep having repeating key issue when paired with my Macbook. The Kinesis CS unhelpfully blame Apple's BT stack implementation and offered no solution. I never had issues with the keyboard when connected to a Linux machine, so this will work nicely for my home office setup!

I'm assuming this also works with Pi Zero 2 W? (The repo only mention the original Zero W)

tanvach··on Bypassing regulatory locks, hacking AirPods and Faraday cages
Don’t know if running the microwave does much, since there are plenty of 5Ghz access points around too.
tanvach··on Show HN: I made a tiny device for automatically recording digital pianos
I am as far away from the target market as possible, but just want to say a lot of things about this device, from the use cases, the design and the UI, feel so delightful. Good luck with the launch.
tanvach··on 3D Rotation Design
I accidentally found how to do this while using a solid modeling software and use it quite a bit. I don’t see a formal name for this maneuver, or anyone teaching it. ‘Gimbal tumbling’ is the closest description.
tanvach··on Ask HN: What Are You Working On? (October 2024)
I'm making a battery powered e-ink dashboard that uses openai api to summarize the weather and suggest the correct toddler clothing for my son at a glance. It refreshes every hour and so far been pretty good at catching things I might forget, for example wind chill and sun exposure.
tanvach··on The AI startup drama that's damaging Y Combinator's reputation
Don’t know why the link doesn’t go to the article correctly. Here’s the working link: https://www.indiehackers.com/post/starting-up/the-ai-startup...
tanvach··on Visualizing Weather Forecasts Through Landscape Imagery
Really cool! Thanks for sharing. Is there a reason rpi 5 is needed versus older versions of rpi (which I have plenty)?
tanvach··on Shape Rotation 101: An Intro to Einsum and Jax Transformers
Don’t know if the author will see this: in the table at the end of the article, there is an error where the text description of dot product and matrix multiplication are swapped.

Otherwise - great article! Didn’t know this exists in numpy. A really neat way to express matrix operations.

tanvach··on Self-driving Waymos secure final clearance for expansion beyond S.F
The cars are operated by Waymo, so I have hope it’ll be more well maintained across the fleet.

Interesting, my wife was still on waitlist in SF last week.
tanvach··on Self-driving Waymos secure final clearance for expansion beyond S.F
It's real for us. We had a ride when the driver wouldn't stop talking and the baby was trying to sleep. Not all people are nice.
tanvach··on Self-driving Waymos secure final clearance for expansion beyond S.F
We do, and I have the base with isofix in my own car.

If they keep the 10% mark up over competitors maybe there is still hope.
tanvach··on Self-driving Waymos secure final clearance for expansion beyond S.F
Worth trying to sign up now. The waitlist takes a while.

The app forces you to pick locations that the car can park safely (no double parking) that's closest to the requested locations. They can be 1-2 minutes walk.

Not a big deal for us to be honest, except when going to the theaters in SF, where the car can stop a block away in sketchy Tenderloin.

Same! It's funny how I actually look forward to get into a ride. I've been so used to a crappy experience in Lyft/Uber.
tanvach··on Self-driving Waymos secure final clearance for expansion beyond S.F
That's quite true, but still surprisingly human like to me when compared to, say, Tesla FSD. It will also take longer to call one due to less supply.

If we want nice, relaxing ride with no time pressure then we call a Waymo. Uber is still our go to if we are in a rush.

We actually prefer safer and slower ride, some Lyft/Uber drivers drive way too dangerously for no reason.
tanvach··on Self-driving Waymos secure final clearance for expansion beyond S.F
We take an infant car seat and use the European belt routing (or if that fails due to short belts in American cars, American belt routing) to secure to the back seat.

We recently started using Waymo more often:

- Quality of Lyft and Uber rides have gone down significantly.

- Consistently spacious, clean and quiet cars. You know what you'll get.

- AC always works and not up to the whim of the driver.

- No chatty driver to disturb our sleeping baby.

Negatives:

- Rides have usually 10% mark up over Lyft and Uber.

- Pick up and drop off tend to be a small walk from requested locations.

Forgot one more positive - you can choose a soothing music play list in the car and it automatically resumes in the next ride. Small but really nice detail when traveling with a baby.

tanvach··on The OpenAI board was right
Are LLMs basically ‘pirating humanity’ at this point?

The unauthorized use or reproduction of humanity's work.

tanvach··on Elliptic curve 'murmurations' found with AI
I highly recommend the PeakMath (https://youtube.com/@PeakMathLandscape?si=zQg6bbp2SvfqzKYm) RH saga video series on YouTube for this topic.

They are excellent, and not requiring more than high school maths knowledge to really get quite deep into the mysterious connections between prime numbers, Riemann hypothesis, elliptic curves and L-Functions.

tanvach··on Study suggests a 'dark mirror' universe within ours where atoms failed to form
> A special combination of physics led to a proton having roughly the same mass as a neutron; perhaps in the dark matter mirror, that combination of physics played out differently, causing the "dark proton" to evaporate and leave behind a sea of "dark neutrons" — what we identify as dark matter.

I don't think I misread the article. Currently we expect dark matter to be neutral. So if we assume the statement is correct, what would then happen to the positrons and it's charge?

tanvach··on Study suggests a 'dark mirror' universe within ours where atoms failed to form
Curious about conservation of charge - if all dark protons were to decay then there must be also an abundance of dark positrons?
tanvach··on Stellarium: Software which renders realistic skies in real time
love to see what your project repo looks like as a comparison.
tanvach··on DALL-E 3 Is So Good It's Stoking an Artist Revolt Against AI Scraping
I'm assuming you are not an artist?

He did the comparison at the end of the video no?
tanvach··on Mathematicians Found 12,000 Solutions to the Notoriously Hard Three-Body Problem
For me the second book was way worse.
tanvach··on Desmos 3D graphing calculator
There are a bunch of YouTubers making Desmos animations. I haven’t played with it myself, but always find it fascinating with what people come up with.
