daylankifky··on Show HN: I mapped my portfolio into latent space (code included)
My professional activity spans several areas, from software deployment to creative disciplines. I have always struggled to explain how these pieces fit together.

To address this, I built a portfolio that includes a latent-space visualization of my projects. It finally gives me a way to show how the value of an interdisciplinary profile emerges.

I also released the code so others can generate similar visualizations for their own portfolios. The repository is linked on the page.

Feedback is welcome :)

The white buttons are a play queue of the last 4 messages I sent. When a new message arrives the corresponding button blinks.

I wasn't expecting so much traffic, it's up again now

yeah, that was the best part. The gift also came with her own first set of (non toy) screwdrivers so she was pretty excited about building it.
daylankifky··on Show HN: Chordata – The motion capture system that you can build yourself
So you were on the production of the first avengers movie?

Something like the kinect can be very powerful for facial tracking. But monocular optical techniques tend to give poor body capture results.

Thanks! It is not a trick, it's what's called a Sensor fusion algorithm. They come in many flavors, we currently implement Madgwick's one. Another popular and somehow more robust alternatives are Kalman filters, we'll probably also implement one of those in the future.

They all rely on absolute references (gravity and magnetic field) to build a non-drifting reference frame which is used to correct the integration of (angular) accelerations.

That's kind of the type of user that this project targets. The idea is to put on the independent creator's hands the power to accomplish motion capture in a flexible and inexpensive way.

The fact that the license will probably keep big companies away doesn't necessarily means that the project can't succeed. Just to name some examples on the non OS environment:

-Slic3r, the tool that virtually started the domestic 3D printing revolution. AGPL license, 8 years of heavy development, 91 contributors and more that 6000 commits on github.

-Blender, the powerful 3D creation tool. GPLv2, 25 years, now receiving good financial support from many top-tier companies and from the community.

I don't know if you took a look at the current Low-cost mocap panorama. It's an interesting environment where many changes are happening. We felt like there was a place for a community driven project.

Well, the main software components are GPLv3. But there's also hardware released as CC-BY-SA, some modules as Apache v2.0. I guess you are thinking of it as a library.. In that case you can argue that a copyleft license would restrict the possible adoptions of the system. But this is a framework composed of many modules, most of the time you will interface this system with your own stuff using agnostic protocols, so.. what would be the legal problem for a closed-sourced business to use it?
