In a recent interview [1] Elon stated that empty booster "has the density of an empty beer can" which is a great mental aid. So it will certianly float. But part of it will be underwater, initially the very expensive flamey part (

The odd thing about "dumb labor" is that many of those tasks are only easy for humans. Dealing in a messy world of human-to-human interfaces and cluttered unstructured worksites is generally hard for robots. The dog for instance m

If we charged industry fair costs for dumping pollutants into water, land and air on Earth - we would have no uncosted externalities. If we then pointed out that in space or on the surface of a lifeless rock there are no costs of pollutants

There are a couple of major reasons the FAA is involved: 1. Fuel-air explosions at ground level can injure people or destroy property (even kilometers away) 2. Rockets on unplanned trajectories can ruin people's day 3. Lots of fuel is

I think the best way to save the planet is to move heavy industry into space. Move our power generation into space and beam it down. Make advanced technologies in space which benefit those on Earth. Move people into real orbital habitats. M

I concur, though most of the traits you mention are not problem-specific. When putting a language into "your toolbox" you indeed SHOULD focus on "popularity, maintainability, being able to hire." However, when picking wh

Personally I think programming language is about a compromise between performance and convenience. For instance, I program in Python if speed is irrelevant. Rust if it is very relevant. C# if I want a large project where performance is some

You make an interesting point. I was a teenager during that critical period myself, or perhaps just after. However, those who love tinkering with computers and technology of their own accord have far more opportunities and resources than we

Female self-destruct gene somehow ends up in a different species. Via virus (which can transfer DNA segments) perhaps. Hopefully far-fetched.

The modified genes (or a later mutation) provide some advantage to their offspring, combined with a failed self-destruct. That causes the population of Mosquitoes to become more troublesome. Hopefully unlikely!!

One idea I liked was ... You have an authoritive world simulation server, as usual. You then have several servers whose chief job is to keep clients in sync with the authoritive server. Most network games combine these two roles, but there

Wonderful! Thanks for sharing. This sounds like the exact sort of work that Rust is perfect for. I'm making a game in Rust and Godot (engine) and since it's a factory game the simulation performance is important. Rust means I worr

I agree. I think you'll find that most rational advocates for any language agree that their favorite language is only strong in its subdomain. Any compiled language is more painful than a quick scripting one for quick projects where th

> in C I'd be tempted to reuse a buffer allocated for one purpose ... In rust I'd just declare an enum for this. Enums in Rust can store data. In this way they are like a safe union.

The very short version: There are many things which cause both frequent and rare strange crashes in multi-threaded code. In C, all these things will compile OK. In safe Rust, practically none of them will compile. It is much easier to fix c

Once you visit a site, you then open the uMatrix tab provided to decide which 3rd party scripts you will allow to run. Typically you only enable a few. I'd much rather know about tracking this way (the list of 20 blocked scripts) than

You need to install DDG privacy essentials, uMatrix and uBlock Origin. Then you won't even see those banners, since they no longer load (along with any of the related tracking)

Suborbital point-to-point transport using a StarShip does not require a booster. You only need a booster stage if you need to accelerate to orbital velocities. That brings the cost down dramatically. A major reason the StarShip is going to

Perhaps you are not thinking faster, instead you're doing an excellent job at focusing all of your resources on one problem. It is the sum of all your thought that is (apparently) fixed, so moving all that thought to one task will have

Unfortunately this. Or they will say "don't optimize it until it proves to be slow in production" - at which point it is too dangerous to change it.

These problems come down to which programmers were allowed to remain on the team and how much they were allowed to change. So all similar performance problems will remain.
