Comment This analysis doesn't actually hold up... (Score 4, Interesting) 93

The obvious slant here is to say that Spotify is just doing what Facebook and Youtube are doing -- algorithm selects content to generate "engagement" rather than actual enjoyment, in turn to drive more user time spent on the site, so that they can sell more ads. Except that Spotify doesn't make most of their money with ads, something like 80% of their revenue is from subscription fees so that doesn't really hold up. There's very little "network effect" in music services, about the only thing that keeps me using Spotify over other streaming options is that they've got a good idea of what music I like and can find new stuff that matches it (or, more commonly, old stuff that I just didn't discover when it was new), and that's precisely what the article is claiming Spotify DOESN'T do.

Comment People confusing the Internet and the Web, again. (Score 1) 54

This is yet another case of people confusing the Internet with the World Wide Web. The Internet is not information -- it is a network over which information is transferred. As such it is made up of networking equipment, routers, switches, cables, etc; the collective weight of which is surely many thousands of tons.

Comment Re:Ringworld, maybe. But sphere? (Score 2) 45

The stability question isn't about the tensile strength and other mechanical properties of the structure itself, it's about the orbital mechanics. A ringworld orbiting a single star is stable on a "peak" position, where any movement away from that position results in net gravitational forces that move it further away. In contrast, the stable lagrange points are positions where small amounts of movement away from that position result in graivtational forces moving it back towards that position -- a "valley" by comparison.

On the abstraction layer -- I suspect you've never had to work on a codebase that was written without abstraction and then later ported to different hardware platforms. Too much abstraction results in code that is bloated and slow, but too little abstraction results in code that is buggy as hell and impossible to maintain. Slow but correct beats fast but wrong every time in my book.

This isn't necessarily Amazon's fault. In an attempt to fight traffic congestion, a lot of cities have started limiting how many parking spaces companies are allowed to install at their offices, so as to force employees onto the public transit they wouldn't use voluntarily.

Comment Re:No reverse thrust (Score 5, Informative) 44

From what I've been reading, the current theory seems to be that one engine failed, the pilots made a mistake diagnosing it and shut down the wrong one (this happens distressingly often), then panicked and did a no-flaps, no-gear landing despite the backup options that existed to deploy either one. That meant a high landing speed, no brakes, and a plane that "floated" in ground effect longer than normal so it touched down halfway down the runway. Then it hit the antenna berm/wall. Note that some distance beyond the wall are things like trees and houses, so letting the plane slide further into those would not necessarily have produced a better outcome.

The investigation will answer these questions. If the above is true then while the wall would be a contributing factor, it would not be primary cause.

Comment Not entirely pointless (Score 1) 26

SSTOs still have some advantages over landable/resuable staged boosters. Most people think the idea of propulsive landing is unlikely to be considered safe enough for a crewed vehicle, whereas an SSTO spaceplane has a lot more backup/abort options since it glides to a runway. That SSTO also has a theoretical faster turnaround time as well, since it also takes off horizontally from a runway. No need to restack your rocket, you don't need an expensive Starship-style launch pad and water deluge system, etc. It also helps the sonic boom problem that has been in the news for Starship lately, since the transition from supersonic to subsonic happens at higher altitudes.

But yes, there's less interest in aerospikes and thus less funding now that SpaceX has changed the market.
