Take something that looks like it might be copyrighted to Kinko's and ask them to copy it. They won't.

I have been to Kinko's dozens of times. I have copied pages out of book, manuals, and magazines. I have also brought in many downloaded PDFs, including complete technical manuals. All of this stuff was obviously copyrighted. Never, not even once, did they even hesitate to let me copy it.

Of course then they'll run into copyright issues

I have yet to hear of a single lawsuit based on 3D parts. Even if there was, all legal precedence says that it is person ordering the part, and not the service provider, that is responsible. Otherwise Kinkos would have never existed.

so probably best just to sell the units.

Then they will likely lose to other companies that are willing to offer parts-as-a-service. Staples already has 3D-print-on-demand at a few of their stores.

The world doesn't exist solely to accommodate your lifestyle.

If a business accommodates the customer's lifestyle, it will prosper. If it does not, it will go out of business.

Just be honest about your motivations and actions instead of rationalizing.

Nope. I am going to continue to rationalize. I have better things to do than sit around feeling guilty.

Home Depot has a tool rental program. It would be really slick if they offered 3D printers for rental, either in-store (it could print your part while you shop), or take home for a weekend project.

This past school year I helped out with an after-school programming class at my son's elementary school. One of the projects was to design a 3D part using Python and FreeCAD. We tried to have the parts printed at TechShop, but they wouldn't let kids under 18 into their facility. So we had them printed by an online service and mailed to us. It would have been really cool to have a 3D printer at the school, so the kids could see their parts being made, and maybe fine-tune the design and print again. One of the boys designed a working toilet for his sister's Barbie dollhouse.

Renting the DVD form the library, or buying it in the store.

This doesn't work for me. My wife and I don't watch movies alone, only together. We are both workaholic nerds, and when we are both free to watch, and in the mood for the same type of movie, it is always a random spur-of-the moment thing. Renting a DVD requires far too much prior planning.

For that matter, Scotland might not be Britain by the time it's built.

1. If Scotland votes to leave the UK, then the spaceport will NOT be built. The whole point of this proposal is to encourage the Scots to stay, so they get all the spaceport jobs and prestige.

2. If Scotland votes to stay in the UK, then the spaceport will likely still not be built. Once the referendum is over, there will no longer be any political reason to continue, and technically, Scotland is about the dumbest place in the world to build a spaceport. It is way too far north, and is due west of major population areas in northern Europe.

That all the work to prevent piracy of movies is paying off.

By far the best way to prevent piracy is to make it convenient for people to pay to see the movie. I have a Netflix account, Amazon Prime, and Apple TV. Yet 90% of the movies I want to watch, even relatively old titles, are not available for streaming. So I can either pirate or not watch the movie. It is easy for me to rationalize the piracy, since the alternative (not watching) also results in zero revenue for the studio. I would pay for the movie if it was available.

Comment Re:PWM? (Score 1) 202

You can use a software based solution that utilizes the PWM or PCM chip to generate pulses, and will let you drive 8 or more servos at a time: []

Software PWM is not going to give the same smooth movement, and will result in both audible hum and vibration. It is fine for dimming an LED, but not for precision motor control.

You are missing the GP's point here.

He is not missing the point. Sure, chess is a good brain exerciser. But there are plenty of other activities that are just as good, but are also actually useful in their own right.

When I was in high school, I learned to play chess well enough to compete in tournaments. I also became a pretty wicked Go player. In hindsight, I consider all of that a waste of time, and I regret it. I should have spent that time becoming a better programmer, a better circuit designer, or a better writer or even better at conversation. Those things would have actually made a difference in my life.

Now that I have kids of my own, I have taught them both chess and Go, but only at the friendly-game level. We spend a lot more time playing with Lego Mindstorms, and writing games in Scratch or Python.

Comment PWM? (Score 1) 202

Does anyone know if the additional I/O lines include any hardware PWM pins? TFA doesn't say. The old RPi-B has only one PWM pin, which is insufficient for keeping two robot wheels in sync, running an X and Y axis on a CNC machine, etc. Even one more PWM would be great. A total of four would be better.

The amount of arable land in the world is fixed.

In America, the arable land is owned by less than 3% of the people. In Ethiopia, it is 80%. So Ethiopia should be richer, right?

Concentrated wealth does not create jobs, distributed wealth does.

America has 492 billionaires, while Ethiopia has none. So Ethiopia wins again.

If people cannot afford to buy new shoes every year then there will NOT be a shoe factory

Yet in America, where people buy plenty of shoes, there are almost no shoe factories. In Vietnam, where most people cannot afford to buy new shoes every year, there are plenty of shoe factories, more than any other country.

It takes two people to create a job: one to offer the position, and one to accept it.

Unless they are the same person. Billions of people are self-employed. Employing yourself is by far the most common way to get rich. People that seek out, or create, opportunity tend to do much better than people that sit around and whine about nobody handing it to them.

those who offer the positions are greedy ... I wouldn't consider them to be any more virtuous ...

Indeed. This is why economic systems that harness greed (e.g. capitalism) are far better at generating prosperity than economic systems based on virtue (e.g. socialism).

With an economic model based on the exploitation of scarcity of resources ...

Except that our economy is mostly NOT based on the exploitation of scare resources. Someone writing code is not "stealing" from anyone else. They are creating value from nothing. The raw materials (petroleum and metal ore) in an iPhone is worth about 5 cents. The main commodities that our economy needs (oil, coal, iron ore, silica sand) are not "scarce", and it is absurd to claim that poor people would be better off somehow if they were left in the ground.

they don't care as long as its some homeless 'bum'

So if we close all the diamond mines, we will no longer have homeless bums? Sure. Whatever.

can we really quit bitching about people who make something of themselves???

Many people have a "zero-sum" mental model of economics. They believe that there is a fixed amount of wealth in the world, and therefore, if some become richer, others must become poorer. Although some people become rich through corruption and rent-seeking, most get there by creating wealth rather than just concentrating what was already there. Rather than pushing others down, they pull others up by creating jobs and demand. But there are plenty of people that don't see it that way. Enough to support political parties and governing majorities based on their misguided beliefs.
