I've had allergy immunotherapy shots going on 30 years now. I'd say there has been an improvement, but... is the technology going to get significantly better anytime soon? I'm skeptical - but happy to be convinced otherwise.

Tons of data that the drops are an improvement over shots, if only for the patient experience! “Patients who have done [allergy drops] and finished a course are now free of taking any allergy medications and they don’t have symptoms anymore.” Dr. Sandra Lin, video interview, Sublingual Immunotherapy (SLIT) for Allergy Treatment: Johns Hopkins | Q&A, author of Efficacy and Safety of Subcutaneous and Sublingual Immunot…

You can use almost any 2D matrix barcode as a fiducial, and those include error correction/detection already. Signing it would be easy.

I’m familiar with ARUCOs, but in my experience they tend to be somewhat finicky (Eg: mid-identified with a little bit of noise or unfavorable lighting), and accurate poses tend to require a lot more fiducial markers than might be considered “reasonable”.

1) Fiducials. This makes it so incredibly easy to map the physical world to the digital world, and vice versa. I guess it’s not under the radar, but it just feels like such a superpower. Sub pixel accurate 6dof tracking & unique identification for anything you want. It’s like a cheat code for computer vision as it makes the whole problem trivial. I half expect fiducials on all public streets within 10 years. On every…

" No, they won't. By definition, FPGAs always give you less performance per dollar than custom silicon. If they can't afford an expensive computer, then FPGAs and the tooling to use them is even more out of reach by a long way.

By the working analogy here, Linux is also at a disadvantage because it doesn’t run the majority of commercially supported consumer software yet many people still use it. It has shown that people are willing to choose free options even if it’s technically less advanced than closed options. A fully featured de10-nano board costs ~$150 [1] so it’s readily accessible, at least in comparison to desktop pcs. [1] https://w…

Fiducials. Yes good. The more the better. But we humans cannot read them. So use UV or near infrared instead of visible spectrum. Same low-cost sensors, less territorial conflict.
