Comment High-power industrial civilization may not last. (Score 5, Insightful) 196

Records of human civilization go back over 3000 years. Industrial civilization goes back less than 200. A good starting point is the opening of the Liverpool and Manchester Railway in 1830, the first non-demo steam passenger railway. There were earlier locomotives, but this is the moment the industrial revolution got out of beta and started changing people's lives.

Only in the last 80 years or so has human exploitation of natural resources been able to significantly deplete them. Prior to WWII, human efforts just couldn't make a big dent in the planet. Things have picked up since then.

There are lots of arguments over when we start running out of key resource. But the arguments are over decades, not centuries or millenia. The USGS issues mineral commodity summaries. There are decades of resources left for most minerals, but a lot of things run out within 200 years. Mining lower and lower grade ores requires more and more effort and energy. For many minerals, that's already happened. People once found gold nuggets on the surface of the earth. The deepest gold mine is now 4 miles deep.

For many minerals, the easy to extract ores were used up long ago. Industrial civilization got going based on copper, lead, iron, and coal found in high concentrations on or near the surface. All those resources were mined first, and are gone. You only get one chance at industrial civilization per planet.

Civilization can go on, but it will have to be more bio-based than mining-based. Energy isn't the problem; there are renewable sources of energy. Metals can be recycled, but you lose some every round. It's not clear what this planet will look like in a thousand years. It's clear that a lot of things will be scarcer.

(And no, asteroid mining probably won't help much.)

Mars!
John and Destiny left the houseboat parked on a space port pad they had rented at the spaceport at the Meridian Bay dome and got in a cab. Destiny said "I don't want to shop on an empty stomach. Taxi, take us to a restaurant that serves eggs and pork sausage this time of day."
"Wow," John said. "That's going to be an expensive place."
"Well, I'm buying. You said you never tried pork sa

Comment Re:'terminal in a library' (Score 1) 102

Define 'in'.

"In" means at an "dedicated electronic reading point" in a publicly accessable library. Not necessarily the library that contains the paper copy. The main restriction is that libraries may not use this to reduce the need to buy multiple copies to satisfy demand.

This is great for scholars who really need to see some obscure published paper from 1982, and are not near a huge academic library. It's great for people who like to read out of print novels. It won't do anything for people who want to read the latest best-seller when all the library copies are checked out.

Comment Trolley buses. (Score 1) 491

San Francisco still has trolley buses. They're powered from a pair of overhead wires. The current generation of buses also has some battery backup, so if they lose their trolley connection while turning, the bus can get back under the wires on battery power and reconnect.

They're a pain. Too much overhead wire, and limited routes. NYC got rid of overhead wire a century ago, which was a really good move. SF has these mostly because, at the beginning of the bus era when other cities were converting from trolleys to buses, Diesel buses lacked enough engine power to climb the hills.

Comment Re:No, PayPal will not accept Bitcoin (Score 2) 134

It's even worse than that. Apparently Braintree is not accepting Bitcoin themselves. They're passing the buck to Coinbase. Merchants who want to accept Bitcoin have to get their own Coinbase account. Coinbase is a broker; they exchange Bitcoins for dollars and pay dollars to the merchant. The merchant never sees Bitcoins.

Coinbase is flaky. Their business address is a mailbox company in SF. Their address registered with the SEC and FinCen is somebody's apartment. They have a "slow pay" reputation on bitcointalk. They have terms and conditions that make PayPal look good.

Comment COBOL - it's all about the data (Score 1) 387

Nothing ever came along to replace COBOL which took data storage as seriously as COBOL did. COBOL has DATA DIVISION syntax for talking about file formats and databases. No other language has syntax for talking about the external representation of data. This is a lack.

Look at how much code goes into taking data out of an SQL database and into an object in Java or Python. And what a pain it is to change the code when the table format changes. It really is a lack that modern languages don't deal with external data well.

This is a special case of the marshalling problem. Programs are always packing data into some specified form for transport or storage. It's an operation which often needs to go fast, and is a clear win if done in hard-compiled code. Yet there's little language support for this. There are precompilers which compile Google protocol buffer definitions into C++ or Go. There are interpreters for Python which understand a SOAP protocol spec and decode, slowly, the XML accordingly. Those are add-ons. Language support for marshalling is very rare, if not nonexistent.

Comment No, PayPal will not accept Bitcoin (Score 2) 134

Read the article. PayPal is not accepting Bitcoin. Braintree, which is owned by PayPal, sells a shopping cart checkout system which accepts various forms of payment. They're adding Bitcoin for merchants that want it. PayPal is not itself accepting Bitcoin, nor is eBay.

A number of shopping cart systems already offer Bitcoin as a payment method. Braintree is just catching up.

Landing
The alarm woke me up. Still asleep I thought "damned whores" out of habit, thinking we were having an emergency before I remembered that we were due to enter orbit and I'd set the alarm myself the night before. We had been on approach since late yesterday afternoon and would be in orbit and docking with the maintenance facility at nine this morning. The landing boats would already be docked there and we would be on Mars' surface by late this afte

I seldom comment in the stories any more, I just come to read journals. Too much noise, too little signal. I've been posting on Soylent News more lately, it's a little like slashdot used to be.
