It doesn't even need a watermark. Simply a tag in the data stream. Yes, I know a clueful user could strip this out, but most people don't know enough about data streams to properly remove such tags, especially if there is a checksum or some other feature that needs to be recalculated. Such tags are commonly passed on when used in most editors, so it isn't even a new feature.

This isn't time consuming at all. YouTube and other similar channels commonly scan for tags as well for other kinds of meta data, so adding a simple if clause that flags the video as lacking proper licensing is enough to kick it out. YouTube in particular does processing of all videos uploaded into its own proprietary data format for internal storage and does other kinds of processing like scanning for copyrighted content. This is literally trivial in comparison.

The problem is that they are sitting in the middle of a wildlife refuge, and doing any demolition would actually cause far more damage to the local environment than simply leaving them in place. This is both in terms of simply hauling the demolition equipment in and trying to "rehabilitate" the land in some fashion after you have cleared away the mess.

Besides, there is always the possibility that some of those sites could still be reused, and concrete poured in the past for a launch pad is often very useful for subsequent launch site. For instance, the landing pad site at KSC that SpaceX is using to recover the Falcon 9 1st stage components is a former launch site that SpaceX got permission from both NASA and the USAF to clear away the metal on the site and set up the other things (like a radio beacon for the core to find) that needed to be put into the site as well.

Otherwise, the land is not really all that useful and can't be used for anything other than a place to study wildlife or launch rockets. Certainly no commercial businesses or homes can be built in the area unless it is directly in support of launch vehicles themselves. There is nothing else for it to do other than rot away, which has other very useful value in terms of trying to see what actually stands up to the environment of Florida over time and what doesn't.

Yup, the motto of Microsoft truly is:

We take yesterday's technology one step closer to today!

The problem is that betting against Microsoft has generally be a bad thing, especially in the operating system software realm. I've been trying hard to avoid using Windows, but it keeps coming back from the dead each time I try to kill it and switch to Linux due to various kinds of issues. This might be the final nail in the coffin for me though as I may just weld shut any attempt to use Windows in the future.

The Number of the Beast is a horrible introduction to Heinlein, and is sort of the last in a long line of books about Lazarus Long. It purposely went into a fictional tangent of multiverses where literally anything could happen, and it was written as though it could. It was basically written for the hardcore fans of his other books to tie together multiple characters and wrap up dangling storylines as a capstone book to his entire collection. It would be like watching a TV series final episode that has been running for many years, and you trying to make sense of what was going on when it was the very first episode you ever watched.

No wonder you couldn't figure it out.

Of books I'd recommend, "Have Spacesuit, Will Travel" and "The Man Who Sold the Moon" are much more approachable and don't contain characters from other books (although Harriman does show up in some other books too). "Friday" is one of his more recent books that IMHO is pretty good too, but was written in the "Dirty Old Man" stage of his career none the less.

If you absolutely don't want to take on Heinlein or feel like not reading any other books of his, I'd then suggest reading some Isaac Asimov... especially the Foundation Series. Unfortunately those stories do need to be read in order though.

All of that meant that he completely missed the story in the book itself. It would be like telling the story of the Lord of the Rings from the viewpoint of Sauron and making it very sympathetic to his viewpoint too, portraying Gandalf as a stupid idiot sent to torment him. I could use other examples, but at least Peter Jackson was a fan of the Tolkein books. Verhoeven hated the political philosophies of Heinlein and didn't even really bother trying to finish the book itself before finishing the screenplay.

The point here is that "The Moon is a Harsh Mistress" is likely to become the same kind of crap that misses what it could become if it was made by a genuine fan of the author and book. The adaptation, while perhaps a bit funny, misses some of the key undertones of the book and what actually sets it apart from an ordinary story.

I only hope that a real Heinlein fan will eventually do his books justice. The only film that has done his stories justice is "Destination: Moon", and that is partly because Heinlein himself was on set for much of the film shoot as a technical adviser.

In fairness to Blue Origin, the "Do X" happens to be "Make a rocket launch, rise up to a substantial height, and bring the rocket safely back to the Earth in one piece".

Blue Origin has done that, although the "great height" is debatable. Their New Shepherd test flight is impressive engineering, although watching the Falcon 9 test article fly in Texas is IMHO far more impressive. SpaceX flying a rocket into space (the 1st stage actually gets past the Kármán line even though it doesn't get to orbital velocities) and bringing it back to the ground safely is definitely much, much more impressive. They haven't had the rocket return successfully mainly because of pretty lousy weather in the North Atlantic Ocean on the last several launches, including one storm that nearly destroyed the barge. 30 foot swells overwhelmed the stabilizers trying to keep the barge flat and level.

It could be treated as a defensive patent. Basically saying that the whole concept of patents stink, but as a necessary evil since they do exist we should try to get a bunch of patents anyway to make sure our competitors don't sue us into the ground with patent lawsuits of their own. It becomes a massive patent war where you can charge back with your own patents, or go after trolls because you not only have prior art but have prior patents that should have been cited by any subsequent patent claims.

Prior art is one thing, but a prior patent takes precedence like none other in federal court. For that matter, a prior patent is useful even if it has expired.

"I don't want to hear about it. It's guaranteed to be invalid on the basis of obviousness, but if they get lucky in court and I've actually read or even heard about that specific patent they'll be able to take us to the cleaners."

This is one of the aspects of the whole concept of a patent that to me invalidates why patents even have a right to exist. The purpose of a patent, according to the U.S. Constitution, is "To promote the Progress of Science and useful Art". I fail to see how the current system even attempts to secure that goal if engineers are basically prohibited from even hearing and talking about various patents.

SpaceX keep changing their mind, it seems, as to if they will continue to use the barge after they get FAA-AST clearance to land on the landing pad at KSC. It appears as though they want to keep the option available for either super heavy launches that push the fuel envelope, like what can happen with the GEO launch that just happened, or for trying to recover the Falcon Heavy central core (which will be quite far down range when it finally does stage separation).

For many launches though, they do plan on eventually going back to the original launch site if possible. On the other hand, there are two barges that SpaceX is using, with one on each coast at the moment (the west coast one being kept near Los Angeles when not recovering rockets from Vandenberg).

Those who support the patent system claim that their purpose is to disclose all of the information that somebody "skilled in the art" (aka somebody trained in that specific engineering field with credentials, degrees, or some other recognition of competence) can take the information disclosed in the patent and be able to duplicate the invention.

In former times, the USPTO actually required either a copy of the invention or a working model to demonstrate the concept. Thousands of these models can still be found floating around the USPTO building, including some funny perpetual motion machines that have been tried before. The working models at least forced the patent developer to show that the idea was physically possible.

I might even buy this argument, assuming that it was possible with the patent application and supporting documents to be able to treat the USPTO as a sort of archive of technological knowledge. Unfortunately, as you sort of point out, it doesn't do any of that, nor is there any way for an engineer to be able to dig through the stacks of patent applications of years past to try and come up with some interesting ideas for future products or even simply to figure out how something worked, like the Saturn F1 engine (or something comparable from 50+ years ago).

The current patent database is a waste of paper, time, and effort beyond a way for large companies to grind into the dust any small company that can't afford the patenting process. It is IMHO the single best thing to shut down small business development and kill job creation in general. I have to presume those are goals for politicians who support the patent process?

Countries can't do it, because it costs too damn much. It isn't just focusing on the problem at hand, but making it much cheaper to put things into space... a task that governments are ill suited to perform as well for multiple reasons. The economic justification for going to Mars simply isn't there.

I also have doubts that even the supposed $10 billion figure that Mars One claims to be able to raise is going to be sufficient to pay for everything needed on Mars for even a small crew of say a dozen people.

...and what is the survival probability of a soldier on the front lines of war?

Surprisingly, pretty good. I've seen figures of less than one bullet in a thousand fired in combat even hits a person, even with highly trained soldiers on both sides that are even trying to aim... like was the case at the Battle of the Bulge during World War II or fighting in the trenches of World War I with aggressive attacks. For soldiers in some of the more recent wars that the USA has been in, you have a much better than 90% chance of surviving combat engagements, and for some units definitely higher than 99% of the soldiers will return home without any combat injuries of any kind beyond PTSD. If you can get a medic to get ahold of you and pull you from the front line, your odds of survival even with combat injuries are pretty damn good.

This is a pretty lousy example to give.

Explain how the Mars One people are getting there, and with what funding, and I'll stop calling it a scam.

You're missing the point. Nothing gets done if people don't just start doing it.

I would agree with your basic sentiment, but my problem with Mars One and the guys trying to do this is that they are biting off far more than they can chew by going to Mars in the first place. If the goal is to get people into space, they should start out by simply getting private individuals into space (including some of these "candidates"). It is proven technology, where flight slots are definitely available for a proven price (currently about $50 million per seat) and a whole lot of eye candy and places to film in even exotic locations like Star City, Russia to show what it is like to go into space.

Yeah, lets do this thing, but do it on a reasonable level first before you decide to bite big and try to do something that all of the largest spacefaring countries of the world combined simply can't do right now. It can be done on a bite sized basis where these producers could earn some credibility before going to Mars.

Mars One most definitely haven't done that.

These guys definitely deserve to be heckled right now as there are basic questions even related to the physics of how they plan on accomplishing this thing they propose, much less trying to work out how they plan on getting it financed with fanciful scam artist style projections of future income that is most definitely not proven.

One day we might be able to have a stable society that doesn't rely on continual expansion for the fringe mentalities and trade/distraction with the preexisting societies but we definitely aren't there yet and at 300 years our greatest nation is about tapped out with a continually bloated government and is getting set in it's ways (at least if the modern economic environment is any indication - which would difficult to argue against).

There is such a stable society. It is called a hunter-gatherer society where people congregated into groups of roughly 100-500 or so people (usually splitting into two or more groups when it got to that larger size even if they still maintained relationships with those other groups). The problem here is that cities were built that broke that kind of society where the hunter-gatherers have been pushed to the fringes of the world and quickly disappearing as they get pushed into increasingly marginal land.

What hasn't been mastered is the concept of a city, especially when the number of people gets over a million or so people in that city. That is also a very new concept, where it wasn't until the late 18th Century that London & Paris reached this milestone of size and became the major industrial cities that we know today.

There are a couple earlier historical examples like Rome and perhaps Yaodharapura (home of the Angkor Wat). Neither city was sustainable at that size. Mostly, our experience in dealing with industrial societies is mostly stuff found in the last century or so and by even historical standards so recent as to not have much of a precedent to even compare against.

Money will say more in one moment than the most eloquent lover can in years.
