Comment Re:Wrong type of machine for Dremel (Score 1) 105

I'm a little surprised someone hasn't come out with a machine that does both. You extrude the parts with a regular disposition machine, then it goes back over the model with fine tools to do cleanup and fine detail work. Probably a little too complicated for the industry currently, but it's something I could definitely see in a premium product at some point.

Actually, as Americans we have many rights not enumerated in the constitution.

All of that being true, there is still no "right to know" when applied to "everything that everyone in the government knows". For example, there is no "right to know" that the ambassador from some certain country is a dick and the best way to deal with him is to scratch his back a lot before asking for anything. What do you learn from that, and what does it benefit you to know? On the other hand, the idea that he's a dick is really counterproductive to future negotiations but is good to know so those negotiations can be productive.

And that kind of information is some of the really secret stuff that we all had a "right to know" from the Wikileaks documents.

Point taken. However, as Americans, we do have a right to audit our government and the actions of its officials. Too much of what is being done in our names (and everything the US Government does is done in the name of US citizens) is hidden from us. Especially the power grabs by the government (including warrantless surveillance, secret courts and widespread curtailment of individual liberties), the gross incompetence of various public servants, and the lies and obfuscation used to cover them up.

As you pointed out, it probably isn't politic to reveal our foreign policy strategies and/or tactics for dealing with foreign governments. Despite that, on balance, I'm glad Snowden made these documents public, as they've clearly shown the disdain that our government has for its people and for the ideals and institutions that make us a nation.

I do believe that we have repeated history (in this case, history being the McCartney era nonsense with communists) and I think that lines were crossed using the new 'communist' (aka terrorist) threat as an excuse in exactly the same way that it happened during the McCartney era.

Thanks! Now Band On The Run makes much more sense to me!

"... right to know?"

You made that right up. There is no such thing as a right to know.

There is such a thing though, as the right to be free of illegal search and seizure. That's difference between Snowden and Manning. A big one.

Actually, as Americans we have many rights not enumerated in the constitution. That was one of the arguments against implementing the "Bill of Rights" at the dawn of our Republic. Many were concerned that if we enumerated specific rights, it would be assumed that those were all there were.

That is not the case. The US constitution limits the power of the Federal government. It does *not* restrict the rights of the citizens. In fact, the Ninth Amendment clearly spells that out:
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people

Comment What? (Score 0) 353

Isn't this sort of a 2014 version of the phrase "Let them eat cake!"

Parallel statements:
Poor people shouldn't have to ride the bus, we should all just give them cars - and not crappy econoboxes, something nice.
We should give homeless people luxury condos on the seaside.

I mean, if you're talking about a SUBSIDIZED service, shouldn't it BE subpar? Asserting otherwise is to say, in effect, "people who can't pay for stuff, should get stuff as good as everyone else"....no? Why, then, would anyone pay for anything?

Comment If you want a Diet avoid Diet food. (Score 5, Interesting) 294

I have lost 75lbs. Part of it was exercise, and the other part is cutting out Diet food from my Diet.
If I want something sweet, I eat something with Real Sugar.
If I want something fattening then I will eat something fattening, like with real butter.

I am not about organic and all natural. But you should focus more on foods that you know of. They will tend to fill you up and stop the craving.
Diet food, doesn't fill you up or solve your craving. So you eat more of it.

Comment Linux + VM? (Score 1) 334

I would recommend Linux- perhaps Ubuntu - certainly if they have no previous experience that has clouded their minds to believe that Windows is the only possible choice. If they must have Windows, I would suggest that you install Linux + a VM with Windows in it, and configure it to log in and start the VM automatically. The reason being that you can then create a backup copy of the Windows disk and leave it somewhere on the Linux disk. This is for when Windows inevitably gets so infected that it doesn't work, at which point you shut the VM down and restore it to its original, freshly installed state.

(hmm, come to think of it - would it work? I have never actually done it; there may be problems with the activation code or something)

Comment Re:Blastoff From the Past (Score 2) 19

The basic aerospike SSTO design goes back to the mid to late 1960s with Phil Bono's work (and a couple of his patents), and designs by the Douglas (later McDonnell-Douglas) corporation (SASSTO, ROMBUS, Pegasus, Hyperion and Ithacus). Chrysler Aerospace (IIRC) had a similar proposal for the initial Space Shuttle studies. Boeing's "Big Onion" came a bit later, after O'Neill's 1974 "Physics Today" paper kicked off the whole L5/space colony/solar powersat thing.

The designs were revived in the 1980s by Gary Hudson and Pacific-American Launch Systems (Phoenix) and later by General Dynamics (Millennium Express --disclaimer, I helped name it) as their proposal for the DC-X competition.

Yes, New Shepherd was clearly influenced by all that (as have several others, including a Japanese suborbital test vehicle). The design makes sense for a number of reasons:

  • structure weight is critical for SSTO, and the closer you get to a sphere, the better your structure-weight to propellant-volume gets, hence the relatively squat shape
  • the rounded-cone shape makes a great reentry vehicle, with some maneuverability (assuming asymmetric mass distribution)
  • the heat-shield on the base serves to protect against engine exhaust on launch as well as reentry heating
  • aerospike nozzles are inherently altitude-compensating, so potentially more efficient

Of course there are downsides to the design too, particularly in terms of integrating the design so that it's light enough for SSTO, and starting and controlling the large number of thrust chambers (usually at least 16, some designs with 24 or 32).
