Planting trees is fine, but hardly the best use of your time since trees tend to pop up on their own just fine. If you want to sequester carbon, your time is probably better spent preventing the carbon which has already been bound in existing trees from being released into the atmosphere. For instance by burying a tree in an anaerobic swamp. Less romantic, more effective.

Because it's fun? An opportunity to develop skills? Peer recognition? Because you need the software/bugfix/feature yourself and can't or won't make money out of it for some reason anyway so there's nothing to lose? Need a reference to further your career? These are the kinds of reasons I believe in. Do these apply to non-coders?

Comment: Quantum encryption (Score 1) 170

So you make a quantum mechanical system which evolves over time and which only reveals the correct key if observed at the correct time. Observing it at any other time erases (parts of) the required information. Practically difficult to make if we're talking about delays longer than picoseconds probably, but the problem specification didn't include a timescale.

anyone can register an account?"

FAQ says:

It is possible to use accounts that contribute to the line (threshold accounts) as a key to encrypt other account credentials (thresholdless account). So an attacker can know any number of those thresholdless accounts and cannot crack other thresholdless account or the threshold accounts.

Can somebody please reexplain this in a way that a dumb child would understand?

Comment: Re:ABC News: Comm systems shut down separately (Score 1) 382

The transmission was not shut down at 01:07 as I understand it, that was the last automatic transmission from the engine system. These are half-hourly, so you wouldn't expect another one if the plane disintegrated at 01:21.

A curious thing is that the last contact with the pilots was a handover from one ATC to another. The Malaysian ATC told them to contact Vietnamese ATC, which they acknowledged but never did. Normally, you'd do that right away (I think).

You could argue that patents are unneccessary because all innovation could be directly funded by government. That's another discussion, though. The innovations mentioned in the brief were things like http, gnu/linux and hadoop. One of these was government funded, the two others are knock-offs of things that to the best of my knowledge originated in private companies (unix and map/reduce). Of course there is an exchange of ideas between academia, private companies and open-souce projects. All of these also come up with new ideas, but the questions are: at which rate, and how would these rates be affected by the abolishment of software patents in the USA? I'm not at all convinced that the overall rate of innovation would suffer, but the argument in the brief does not contribute to that one way or the other.

Comment: Re:Operating systems were "open source" originally (Score 1) 105

That is a valid example of open source innovation, but can hardly be used in an argument against software patents. If we want a software industry, i.e. companies whose investment in software development isn't recouped through hardware sales, we can't go back to the business model of the 60s. And I think we all want a software industry.

Granted, you may be right about the very start of these fields, but that's a pretty pointless question. If we go with the very start of a field, it would probably be almost entirely academic.

The reason why the very start of a field is important to this debate is that this is where innovation happens, and the main argument for software patents is that it allegedly fosters innovation. That's also why the very first origins of httpd matter when it's being used as an example. Those things that originate in academia are usually not patented, since academia has a culture of publishing without patenting.

The important thing here is not the number of users or developers of a product, but its degree of innovation. As mentioned earlier, innovation also happens on a smaller scale within projects all the time, but if open source is to prove that software innovation doesn't need software patents, as the brief claims, then it should be possible to find widely known examples of innovative open source software. Maybe CMS is one, in which case it should have been mentioned in the brief instead of projects that are knock-offs of various patented and government-funded work.

software patents were practically non-existent before the 90s.

That is evidence that software innovation can happen without software patents. The success of open source (at least as far as it has been exemplified thus far) is not.

Regarding the claim that most fields start off as proprietary, I would disagree

Which fields have started off as open source? You mention CMS and web servers. Web servers started out open source, but since that work was government-funded it's a bit tangent to a debate about software patents. I don't know the history of CMS. Maybe that's a good example.

On the other hand, the argument that patents cause innovation is also false, if based only on the observation that innovations (and many things that aren't) nowadays tend to be patented.

The more they over-think the plumbing the easier it is to stop up the drain.
