Hey folx! You probably see a lot of stuff from other social networks mirrored to Mastodon, how about we do it the other way around?
Recently, I've starred to mirror my posts to Instagram, Reddit, and other platforms, and I've had quite the success. My biggest post on Instagram, which is just one screenshot of a Mastodon post, has 44.5k likes and 256k views. My
«“If I was going to design a facility to grow algae, I would probably design a facility that had a lot of surface area and was very shallow, so you have sunlight down to the bottom. And put a lot of nutrients in it. And that’s pretty much what the Reflecting Pool is. It’s just a perfect facility for growing algae.” The decision to paint the bottom a deep shade of blue, scientists have told me, raised the water temperature and accelerated the growth.»

I can image a developer parallel to the first, too: the human still using all their skills and experience, but with the machine catching mistakes, providing context and validation and vigilance that is •orthogonal to• testing and type checking and code crafting and — the big one! — actually •thinking• about the problem.
That’s a regime I imagine developers would feel a lot better about. And I know there are people out there pursuing it! But they’re not the ones dominating the conversation.

An Information-Theoretic Analysis of Threshold Group Testing
Remco van der Hofstad, Noela M\"uller, Connor Riddlesden
https://arxiv.org/abs/2606.11353 https://arxiv.org/pdf/2606.11353 https://arxiv.org/html/2606.11353
arXiv:2606.11353v1 Announce Type: new
Abstract: We study the Threshold Group Testing (TGT) problem in the noiseless and non-adaptive setting, where the objective is to exactly recover a sparse binary vector from pooled tests, using as few tests as possible. In TGT, each test applied to a subset of items returns a positive outcome if the number of 1's (defective items) in that subset meets or exceeds a specified threshold, and has a negative outcome otherwise. We investigate how the complexity of TGT compares to that of Classical Group Testing (CGT), corresponding to the special case of the threshold equal to one, and analyse the impact of increasing the threshold on the required number of tests.
Our main contribution is the derivation of a sharp information-theoretic phase transition at $c_{\mathrm{inf}}^{\mathrm{TGT}}k\log(n/k)$ (non-adaptive) tests for TGT within the constant-column test design. The threshold constant $c_{\mathrm{inf}}^{\mathrm{TGT}}$ is expressed as a function of the prevalence of defectives and the threshold value. Our upper bound is derived under an analytic assumption, and we verify that this assumption is satisfied for a threshold value of 2.
The value of $c_{\mathrm{inf}}^{\mathrm{TGT}}$ reveals that TGT on the constant-column design has the same information-theoretic behaviour as CGT in the low-prevalence regime. Yet, strikingly, at higher prevalences, the threshold leads to a significant reduction in the number of tests.
On the other hand, we provide evidence that when the asymptotic proportion of defective items is positive, TGT actually becomes strictly harder than CGT (excluding trivial reductions).
