Materialize is based on differential dataflow, that is based on timelly dataflow. The abstraction works like magic: distributed computation, ordering, consistency, storage, recalculation, invalidations... All those hard to since problems are handled naturally by the computing paradigm. Maybe the product is similar, but not the principles behind

Principles only matter to hackers, but the end result for end users is identical. It’s just very unfortunate that materialize has a much much bigger marketing team than the datomic people.

Materialized is streaming, Datomic is poll.

Self-driving cars. Now that the hype is over and the fake-it-til-you-make-it crowd has tanked, there's progress. Slowly, the LIDARs get cheaper, the radars get more resolution, and the software improves. UE5's rendering approach. They finally figured out how to use the GPU to do level of detail. Games can now climb out of the Uncanny Valley. The Playstation 5. 8 CPUs at 3.2GHz each, 24GB of RAM, 14 teraflops of GPU,…

Can't help but laugh whenever I read about self driving cars predictions like this sorry.

My GPS can hardly navigate most of the world I'm not really excited and if the only criteria of self driving car is self driving on a high way then color me uninterested.

I don't think self driving cars will be able to traverse majority of the world's traffic anytime soon. The road is just too difficult to maintain for human free driving with the exception of few major block cities on America which makes the whole ordeal pretty boring.

Even closer to home. Palm, RIM, Microsoft, Apple and Google have all said at one point that web apps were the answer for mobile apps....

I mean, modern Google was half-built on the back of the Gmail web app...

Gmail was introduced after Google was already popular. The Google home page’s claim to fame was always its simplicity and fast load time.

Self driving cars don’t need to be 100% autonomous in all possible scenarios in order to be useful. Self-driving reliably on the highway? Hell yes I’d take that (just think of trucks - having a driver to the highway is so much cheaper than having someone drive it cross-country). Self driving reliably in a few major cities? Oh, you mean cheap robotic taxi?

Velomobiles! A velomobile is a recumbent bike with fairing which enables them to be more convenient and much faster than a regular bike. A fit rider can easily overtake the peloton in Tour de France (https://www.youtube.com/watch?v=UBb7YIRcBe0). The velomobile in the clip is a standard model and there are racing models that are faster still!

Just like with regular bikes, you can add electric assist to them to extend their range and make the job of the rider easier. In this clip (https://www.youtube.com/watch?v=OCo4cRQMBlo) the rider gets an average speed on 37.5 km/h (top speed 84 km/h) over a distance of 73 km with over half the battery remaining. And that is without wearing the racing hoodie which significantly reduces drag.

The main problem with velomobiles is that they are expensive. The frame is made from carbon fiber and needs to be handcrafted. So the price ranges from about €5000 - €10000 which is too expensive to most. If some Chinese giant or billionaire investor set out to mass produce velomobiles I'm sure they could totally revolutionize transportation.

Svelte Flutter Zig, Nim & Crystal programming languages Please.build (bazel clone in Go) GraalVM's native image and CoreRT for .NET (though not much is heard about progress on CoreRT)

I've wanted to try mobile programming for a while (I am a web dev). Is Flutter a good choice for a mobile beginner like me, who hasn't done any mobile programming at all?

I'd say yes, although learning dart maybe take a week or two in worst case. Flutter, as opposed to react native, is quite easy to set up. The declarative UI paradigm is nice.

I don't like to see wasm replacing native for stuff like development tooling, and desktop apps. JITs may approach native performance in theory - but the battery consumption and memory consumption are not very good. ("Better than JS" is a low bar). As hardware becomes stronger, I would like to do more with it, and when it comes to portable devices, I want more battery life. Nothing justifies compiling same code again…

> I don't like to see wasm replacing native for stuff like development tooling, and desktop apps. Wasm is like the JVM or CLR in that regard. It's not the future - it's the past.

Yes. Even if there were a number of dominant architectures, install-time compilation would be better than run-time compilation for frequently used software. The RAM and Energy overhead isn't just worth it.

1. Cloudflare Workers, I don't have the bandwidth to experiment with it right now but it interests me greatly. https://workers.cloudflare.com/ 2. Rust - definitely will be the next language I learn. Sadly the coronavirus cancelled a series of meetings in Michigan promising to give a gentle introduction to Rust. https://www.rust-lang.org/learn

At my company, we run 100% of our front-end React/Vue web apps on Cloudflare workers - We love it, deploys are really easy, performance/resilience is built-in

Materialize https://materialize.io/ Incremental update/materialization of database views with joins and aggregates is super interesting. It enables listening to data changes, not just on a row level, but on a view level. It's an approach that may completely solve the problem of cache invalidation of relational data. Imagine a memcache server, except it now also guaranties consistency. In addition, being able to liste…

It looks similar to couchdb?
