You got to have a paid subscription to read the article. The main output of remap radio is a (number of) podcast(s). The written game criticism articles is an extra.
They claim "By signing up—again, it costs nothing!—you can read the rest". If that's false, that not only a really shitty move but should be a crime - they're obtaining something of value (your e-mail address, no doubt to spam it with subscription ads) under false pretenses.
A fundamental problem is as the number of parameters increase the probability of sampling from the edge of the hypercube increases. You will then not effectively explore the parameter space. This might be some what alleviated by a concentrated multivariate normal, but I guess that has its own caveat.
If you instead have a sampling algorithm informed by the loss functions you avoid this problem. (You instead might have to worry about local minima.)
They're ordered by the time you accessed each last. I agree that this is, in retrospect, unintuitive and poorly designed. Will be reverting it soon enough.
