zksnarks https://blog.ethereum.org/2016/12/05/zksnarks-in-a-nutshell/ Essentially let’s you verify computation is accurate without doing the computation yourself, and even treating the computation as a black box so you don’t know what is computed. Many applications in privacy, but also for outsourced computation.

One important weakness of zkSnarks is that it requires a trusted setup, for example [1]. A new alternative is called zk-STARK [2], which doesn't require the trusted setup, and is post-quantum secure. However, it significantly increases the size of the proof (around ~50KB). In general, hash-based post-quantum algorithms require bigger size and it would be interesting to watch the progress made in this regard. [1] http…

Rainway: https://rainway.com/ Google Stadia: https://stadia.google.com/ It's not even about gaming. Fuck gaming. It's about the underlying streaming technology. Imagine this same tech being used by a surgeon to perform surgery remotely. That's the type of use case I'm thinking about!

+1, very excited about this. They're marketing it in the OLAP space right now, but at some point I'd like to try integrating it with a web framework I've been working on.[1][2] It'd be a more powerful version of firebase's real-time queries. Firebase's queries don't let you do joins; you basically can just filter over a single table at a time. So you have to listen to multiple queries and then join the results by han…

Thanks for the vote of confidence! One thing: We're not marketing it in the OLAP space. Our existing users very much are building new applications. Initially we went for the metaphor of "what if you could keep complex SQL queries (e.g. 6-way joins and complex aggregations, the kinds of queries that today are essentially impossible outside a data warehouse) incrementally updated in your application within milliseconds…

- Far UVC lights (200 to ~222nm) such as Ushio's Care222 tech. This light destroys pathogens quickly while not seeming to damage human skin or eyes. - FPGAs. I'm no computer engineer, but it seems like this tech is going to soon drastically increase our compute. - Augur, among other prediction platforms. Beliefs will pay rent. - Web Assembly, as noted elsewhere. One use case I haven't read yet here is distributed com…

> Far UVC lights (200 to ~222nm) OK, these are not safe wavelengths, and whatever you're reading is not right. This is absolutely ionizing radiation. The rate of formation of thymine dimers in this regime is similar to that around 260 nm. That is, it causes DNA damage. Please see Figure 8 below: https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1751-1097.... The logic of the claim that you can destroy a pathogen with…

Darklang: https://darklang.com/ I've tried out an early version of their product, and I really like where they're headed.

I’d love to try it if they didn’t tie the language to their hosting service. I understand the necessity of the coupling but until someone can start a competing hosting company with the same language, it’s not something I’m interested in.
