Comment Re:No Backup? (Score 2) 72

I read that as "landing *system* failure". If a plane's engines die it can glide; if its landing gear fails to deploy it can still perform a controlled belly landing; if it's approaching at a bad trajectory it can take another go-around.

Starship has redundant landing engines (at least one prototype landing test failure was because it wasn't prepared to *use* the redundant engines; lesson learned...), but unless they're keeping better ideas secret, the current backup plan if a trajectory goes bad is "fall in the ocean, tip over uncontrolled, and hope not to explode", and the backup plan if a tower catch fails (they're basically putting the landing gear on the *ground* rather than on the vehicle!) is "try again until a slim propellant margin runs dry, then fall onto concrete".

If Starship works at all, this shouldn't be a long-term problem, I think. They'll have loads of opportunities to iteratively improve the system once they're flying it unmanned every week. They may never get to 1-in-a-hundred-billion commercial aircraft risk levels, but they'll be under the 1-in-250 levels that astronauts tolerate in no time.

Comment It's the content (or lack thereof) (Score 1) 109

Most podcasts take the form of a bunch of people at a table, each by a mic, who talk about ... stuff. It's unscripted. Unplanned. Shoot from the hip. And, unsurprisingly, it's also very boring. Contrast that to Rogan, who runs a podcast I despise, but who at least has a producer plan set ups to surprise his guest with something about them or their past they'd rather not talk about. To create tension or conflict. Better, think of This American Life, which follows documentary radio format. A subject is chosen for each episode. It's broken into two or three segments with a matching theme. Producers go out and interview people in the field who have something to say and the quotes curated so you get the interesting bits and not a bunch of wandering commentary. Then there's scripted VO to tie everything together.

Podcasters have conflated disorganized talk with produced and informed commentary. And people got better things to do than listen to boring nonsense even if they're stuck in traffic. I mean, there's always music!

Comment Re:Ridiculous parody. (Score 2) 110

Notice how the focus of 'Birds Aren't Real' is that robot birds are engaged in mass surveillance. Which is ridiculous, but with a tinge of plausibility since actual prototype robot birds have been created. But that's not the point. Forget birds. The point here is to dismiss robot birds as replacing all real live birds and in the process diminish or demean the concept of mass surveillance. Which IS REAL. I mean, we're all carrying phones with GPS tracking our every move, audio recording (which has been subpoenaed in the past) , and leaving video records these companies analyze for whatever reasons they choose.

The birds, not so real. The mass surveillance part, very very real. And I get the sense this movement benefits surveillance capitalists more than it debunks fake conspiracy theories.

Comment Pixel 2 / Yamaha motorcycle. Works fine! (Score 1) 132

I have an old Google Pixel 2 which I regularly mount to my Yamaha motorcycle handlebars and I've never had a problem. Camera works fine! Use it with a PacTalk to bluetooth stream music or Google Assistant from the helmet. Would definitely choose an old or cheap phone with enough oomph to do maps and spotify over a mere GPS. Would not buy a $1000 iPhone anyway. $300 will get you a perfectly good last gen phone that will last several years. And if you break it, buy another and don't shed a tear.

Comment Ultra high voltage DC transmission (Score 5, Informative) 263

China has deployed a one million volt DC electric grid transmission system which, is efficient at several thousand kilometers. They are deploying solar, wind, hydroelectric and nuclear as fast as they can. And not focusing on storage but instead a national transmission grid. Solar in the northwest where it's still light and transmitted to the south east where it's dark in summertime, especially for hvac cooling. Invert that for winter.

We could do the same thing. And in fact we desperately need to upgrade our electric grid anyway.

Comment This is not possible (Score 2, Interesting) 44

A wallet is nothing more than software and a unique crypto key. There's no way to verify identity of wallet holders unless the owner registers a wallet to an official exchange. The blockchain will record chains of transactions to keys, and regulators are welcome to trace those transaction records as much as they like. But it won't get them identity of key holders or the location of a transaction anywhere in the world. Which means, in what jurisdiction did that transaction take place?

Want cash for bitcoin but don't want regulators to know? Trade bitcoin for dirty cash from drug gangs. You get dirty cash and they get bitcoin. They use the bitcoin to buy large quantity drugs. You use the dirty cash to pay fake rent for an empty apartment to get it into the local banking system. This is at least one way bitcoin is used for money laundering. And it won't go away with a mere law. Because bitcoin (and most every crypto currency) is unregulatable at the protocol and intended to be that way.
