Working on a fully automated UV unwrapper for 3D meshes. Its basically the process of flattening a 3D object down to a square. used mainly for texturing. http://www.ministryofflat.com

Regarding your twitter question: you can create an anonymous temporary file with no name or backing store since recently (4.x, iirc). You should be able to use dup(2) and unix sockets to send the descriptor over.

Thanks! What i cant work out is if/how dup can be made to be owned by a different process. it needs to be only accessible by that process and should be removed once that process dies. I would like to separate the transfer, of the handle, and the translation of the handle.

This is very cool. As a sales person, the ability to set an upfront agenda and make things interactive for prospects (within a first meeting especially) is important. I have ways of doing this today but I'm always open to testing new strategies and technologies. I'm in the process of creating a few meetings in QuickIntro and keep hitting the error of "[object Object]" when trying to save or "Create meeting." Any guid…

Thanks for checking it out and sorry about that bug! Do you mind shooting me a quick email at pedro@quickintro.app so I can troubleshoot it with you?

Awesome, I just shot you an email now. Thank you for the help.

Staying sane by staying busy. My wife is slowly dying and is a thousand miles away at a hospital, hoping they can save her. Today I cleaned a workshop area that I'd been using for storage so that I could use it as an actual workshop. I have car parts to rebuild (Chevy 350 TBI at least) and I have things to build, like a recumbent bicycle from scratch. I am also working on learning CW (aka Morse code), learning to pla…

I ask a lot of questions here sometimes. None of them have been nearly as rewarding at this. If you ever need a remote-buddy to discuss/hack on things, let me know. I can't imagine what you're going through but it's good to remain positive and productive. My email is j.horne2796@gmail.com

Polygons are 3D and textures are stored in images (2D). So you need to have each polygon in 3D space correspond to a polygon in 2D image space. One way to think of this is to take a 3D model and unwrapping it on to a 2D sheet. Very much like you would do if you would design paper-craft. A 3D artist usually starts by doing the 3D shape, then they create the UV unwrap, and then finally they paint the 3D model in a 3D p…

I got great results with mvs-texturing. It's not as efficient with texture area or the number of textures, however. Does your approach scale to large meshes, at least in theory? I.e., what is the limit you deem feasible with 1TB RAM and a 3GHz dual socket, 14 cores each? Say, within 2-5 hours or so.

I have tried it with meshes in the 300-400 meg range and it works fine. Time depends on the kind of geometry.

Where/how are you sourcing product? Do you have any experience in cosmetics?

A brand called “War Paint”, which I’m sure you’ve heard of, recently created some buzz and quickly attracted a lot of negative media. Did you learn anything from the negative feedback they received?

I quit my job last month to work full time on (what I think is) an under-explored area of climate change: how institutional investors block shareholder proposals calling for firms to adopt more climate-friendly policies. I have just published the first bit of research with data on how 500+ funds from the big 3 fund managers voted on climate change-related proposals in 2018: https://voting.greengovernance.org .

Later this year, I'm planning to launch a "governance-first" ETF that gives investors the same exposure as other funds but is much more aggressive in fighting climate change.

I'd love any feedback! Feel free to email me at @greengovernance.org

I work ~12 hours a day, but in my free time, I like to work on a lightweight, full-featured blog engine. It’s fast, easy to use, platform-agnostic, and I’m pretty proud of it. I ported it to Python 3 last month, and I have some big plans soon. https://zacs.site/blog/first-crack-release-notes-0619.html

We're drowning in emails and Instant Messages and need AI to help make sense of it all. As a former CTO for a fast growing startup I was struck by how often everybody was asking the same questions about connections and skills, and how much time and efforts were wasted in mid-size organizations because of lack of transparency and visibility.

I'm building AntEater (www.anteateranalytics.com) with my team to bridge this gap and empower everyone who uses Gmail and Slack to be more knowledgeable - and as smart as the entire team, using AI. This is a radical shift in terms of information flow in organizations but I truly believe a more transparent workflow will lead to less work and less frustrations.

You can check out the project here - it's free for small teams https://try.anteateranalytics.com/

I've become bored with software. I just started a masters degree in Biology and have a vague and naive plan of becoming a cardiologist and running a lab with the primary goal of reducing human suffering, rather than money (been there, done that).
