I cheated a little bit and don't calculate the fluid dynamics in real time. Instead, I'm using force models from the excellent Aero-Hydrodynamics of Sailing book by Marchaj, which …

SailRhythm is a bit WIP, so didn't want to share too early! Thank you so much for the detailed feedback. I do have plans to implement wind flow visualization and have a way to visu…

You get water graphics for free from three.js

If other people are interested in sailboat physics -- this resource is a goldmine of information on how sailboat and sails work and physics around it: https://www.onemetre.net/Desi…

Please!

Definitely recommend taking an introductory ASA 101/102/103 classes from a local school! Will help you decide if you are into it while having some fun. This is how I started.

I built one recently to mostly help myself visualize how sail trim worked and how various boat controls like mainsheet and backstay affected sail shapes, various forces and boat pe…

There is a great school called Modern Sailing School in Sausalito. I highly recommend taking a class from them. I took one in the past and they are great! Will help you figure out …

Not my demo! But I got inspired by it some time ago to build a simulator for monohulls which uses a physics based VPP to calculate the boat speed based on input controls like mains…

Even still a lot of information is not online. I've been building a web sail trim simulator and had to hunt down a physical copy of the Aero-Hydrodynamics of Sailing book by Marcha…

This site is an absolute treasure trove of technical material on sail and hull design, with a focus on model yachts but most of the physics scales up. It covers aerofoil theory (mo…

You can now automatically debug native apps from Claude or Cursor using LLDB. Here it is automatically analyzing buffer overflow in a binary: https://x.com/full_duplex/status/19047…

Does this somehow disqualifies SpaceX as a contract supplier?

Considered by who? By which metric?

Land in desirable areas is limited and zoning and other government red-tape prevents high-density housing from being built (or any housing being built period in cases like San Fran…

What's wrong with Mimosas? They smell so nice in spring!

I can't believe I'm arguing that it's immoral to steal on HN, but here we are... Yes, you might decide that breaking your moral code to feed yourself or your family is an acceptabl…

Both are completely immoral.

From the recent stuff, remember the lab leak theory where any mentions of which were getting removed from Twitter, Facebook and Youtube, including the scientific papers that looked…

It essentially became a public square of the internet, so it's important to have it as censorship free as possible.

There was an actual rise in crime, both perceived and statistical, immediately after he was elected. Hell, Boudin ran on a campaign that people like his terrorist parents should no…

The majority of these challenges are direct result of the government's corruption and incompetence. See e.g. housing crisis, or student debt issue, or massive drug proliferation.
