hun-nemethpeter··on Why are there no startups in the real estate construction sector?
There is an Australian company called Fast Brick Robotics ( https://www.fbr.com.au/ ).

https://www.youtube.com/watch?v=zNTMxSUsFrM The third home built using Hadrian X® robotic bricklaying technology in Wellard has reached lock-up stage and is now up for sale.

This four-bedroom, two-bathroom home was built in conjunction with Inspired Homes, a multi-award-winning turnkey home builder in Perth, and features a stylish open plan living area, modern kitchen centrepiece, comfortable home theatre, relaxing bathrooms, outdoor alfresco area and a double car garage.

Yes, the name of this attribute is rankdir.

See in the docs: https://graphviz.org/docs/attrs/rankdir/

In the sketch example:

  digraph G {
    rankdir="LR";

Why do you use sometimes pthread primitives from <pthread.h> instead of standard <thread>, <mutex>, ... objects?

For example src/manager/DNSCache.h use std::mutex but src/kernel/Executor.h use pthread_mutex_t?

hun-nemethpeter··on Why hasn't prefab construction taken over?
I prefer the Fastbrick Robotics ( https://www.fbr.com.au/ ) company's approach where they just creating building robots. Here is a short video on the robot in action: https://www.youtube.com/watch?v=HYsWbDA0xlc
hun-nemethpeter··on Four-day week trial: study finds lower stress but no cut in output
There is a topic on reddit now which can shed some light on this question.

hun-nemethpeter··on Physicists Detect Gravitational Waves, Proving Einstein Right
According to this paper ( https://dcc.ligo.org/LIGO-P150914/public ) they detected the signal first at Livingston, Louisiana and 6.9ms later in Hanford, Washington. The distance between them according to wikipedia ( https://en.wikipedia.org/wiki/LIGO ) is 3002km (Ok, the 3002 km distance is on the Earth). If the gravity wave travel at the speed of light they should detect 10ms later (300 000/3002 sec = 1/100 sec = 10ms ). From these data the gravity travels at 434 000km/sec instead of 300 000km/sec. Almost 50% faster then light... Is there any error in my calc?
hun-nemethpeter··on A look at asm.js and the future with WebAssembly
I linked the official webassembly design page where the authors said compiling from JavaScript to WASM is not possible now.

"jfbastien commented on Jun 24, 2015 JS → wasm will only really make sense once wasm supports GC, and most likely JIT compilation too, which is still quite a while away. This would basically be equivalent to implementing the JS engine in wasm! I mentioned this recently and @BrendanEich accused me of having been taken over by horse_js.

To be clear, wasm's goal isn't to replace JavaScript, it's to supplement it. It's therefore not really a goal at the moment to support JS → wasm, but the features we want to implement will make it possible. I'm not sure it'll be that useful from a developer's perspective, though. You may get some size reduction, but that's about it. From a browser's perspective it may be interesting to have the JS engine implemented in wasm from a pure security perspective."

Compiling from JavaScript to WebAssembly is not possible and makes no sense.
