Dental treatments, besides being very expensive, are often (up to 28%) unnecessary. This happens because no-one keeps dentists in check. I am trying to make dental treatment and diagnosis reviews easy, cheap, reliable and fast.

#132Somewhat of a departure from the rest of the current comments. I'm a dataminer/rom hacker mainly working on Nintendo handheld systems from the DS onward and I've recently resigned myself to learning the sort of ASM code needed to reverse engineer compiled assets (since obviously I have no way of getting a pre-compiled version of those assets). I've been looking into the legality of reverse engineering and I've always…
You were trying to load VR porn on there, huh?

#134Interesting to me, your mileage may vary. Working in my spare time on a command line terminal UI application that searches over source code and ranks the results. It came about from watching a work college constantly opening VSCode when trying to find things in a codebase. I mentioned he should use ripgrep/silver searcher which he tried, but said he preferred to get more context and wanted ranked results. The context…
Looks useful. Would it be fast in huge codebases?
I want it fast, but absolute performance is not a goal as its a trade off with any ranking algorithm. Not really the same sort of tool.
Anyway here is a search over my projects directory which is about 5.7 GB of content https://github.com/boyter/cs/blob/master/large-search.gif
Feel free to try it out if you are able to build from source. It certainly has some bugs in there over large codebases in the UI which I am aware of but does work generally.

#136This problem will only apply to very few people. But over the past 2.5 years I've been tracking everything and deriving insights on my activities. This produced some astounding results. e.g. Chewing gum makes me more comfortable in a conversation. Recently I've found a community of robot-like people on reddit who also do this. So I decided to build a platform. It's still in its early stages but feel free to check it…

#1372.) Porting my Python code for nonlinear gradient driven optimization of parametric surfaces to C++. Includes a constraint (propagation) solver based on Minikanren extended with interval arithmetic for continuous data (interval branch and contract). This piece is a pre-processor, narrowing the design space to only feasible hyper-boxes before feeding design parameter sets (points in design space) to the (real valued) solver. Also it does automatic differentiation of control points (i.e. B-spline control points) so I can write an energy functional for a smooth surface, with Lagrange multipliers for constraints (B-spline properties). Then I get the gradient and Hessian without extra programming. This makes for plug and play shape control. I am looking to extend this to subdivision surfaces and/or to work it towards mesh deformation with discrete differential geometry so I've been baking with those things in separate mini-projects.
3.) Starting the Coursera discrete optimization course. This should help with, e.g. knapsack problems on Leetcode, some structural optimization things at work, and also it seems the job market for optimization is focused on discrete/integer/combinatorial stuff presently so this may help in ways I do not foresee.
4.) C++ expression template to CUDA for physical simulation: I am periodically whittling away at this.

I really liked the idea, just wish there could be a demo, or even a preview without the need to sign up. It would make a better onboard :)
Mostly I agree on hating things requiring a login but I'm okay with it in this case.
