comment Prevent package from being opened in a notebook interface
@AlbertRetey - That would work for many situations. The problem with this one is that the client owns and develops the .NET code. Whatever I supply them has to encapsulate its own protection.

comment Prevent package from being opened in a notebook interface
@AlbertRetey -- I just want to make it harder. I want to limit (as much as possible) their access to my code to NET/Link. The code in the package already restricts use to a specific authorized machine. If not run on the authorized machine the code shuts down the kernel. I'd also like to restrict them further, perhaps shutting down the kernel if the kernel gets accessed from a notebook.

comment Scale plot display area (within the frame)
@Kuba - Gosh, long time, but yes I would like an answer. Reading through the question again, I wonder if I can do something with LogPlot, but I've yet to see think through to a solution.

comment Partitioning time series data in sublists by their duration
Can you supply a simple example of the hierarchy of your data structure? It would help sleepy guys like me think more easily about the problem. Even better, if you can give us a simple function to generate some random data we could use to help design a solution. That said, my first instinct on this goes to creating a dispatch table. See Dispatch[] and @whuber's answer link. A dispatch table just might give you the versatility you need to do what you want to do.

comment Assign the contents of a “Copy” operation programmatically to a variable?
While I can't use this solution on OS X, +1 for helping that other part of the universe.

comment Assign the contents of a “Copy” operation programmatically to a variable?
@Mr.Wizard - Duplicate? Kind of, but the answers, excepting yours, don't provide solutions for what I'd like to see. While yours does (I just implemented it;-), having done so makes me think we can make it better by: naming the palette & supplying steps to install it using Palette -> Install palette...?. Also, even your answer has intermediate steps. A year since the original, might not others have come across simpler or more direct ways to do this? I think a new solution might interest the community, but maybe we could spark new contributions to the original. Thoughts?

comment Assigning weights to edges of a hypercube based on the Gray code labels for vertices being connected
+1 from me. Seeing a solution like this for such an interesting problem, just made my day brighter. Thanks.

comment MySQL or PostgreSQL? Using Mathematica only I need to choose one
@bobthechemist -- I don't think we can regard this as a subjective question. MySQL and PostgeSQL have different capabilities and performance because of their inherent designs. PostgreSQL has more institutional capable performance. Head to head PostgreSQL provides a viable alternative to top tier database base platforms (including the likes of Oracle and SAP) in their core markets. MySQL doesn't really do that. All of this said, the OP has a specific need. Given that one can download both these platforms for free, why not simply test them?

Many thanks for the explanation.

comment MAP a business cycles model
I never had occasion to use RecurrenceTable, so its syntax using equations seemed unfamiliar. A little explanation of how RecurrenceTable and any similarly structured functions work could help we uninitiated, better understand your solution. Its a very cool solution you've crafted. Knowing a bit of your thought on why you chose to attack the problem as you did, rather than some other way (Mathematica always seems to have other ways), would make for some interesting insights. Just curious ;-)

Could you provide a bit of explanation of your code. It has a lot of interesting things in it. +1

comment MAP a business cycles model
I think you have an interesting question in this, but I don't find it sufficiently well formed. If you can provide us with a description of what Phaser 3.0 does and how we can replicate what you have done in it, that will give us a better chance of helping. I even downloaded Phaser 3.0 to try and do this myself, but the version for OS X appears corrupted and won't install. Also, your Mathematica functions need more thought. You have functions calling themselves within their definitions. At 1st glance that looks problematic. I'll give it more thought, but a bit more from you will help.

comment How to improve the performance of this code
As Alex has defined Ei as a function, does he really need to pass it to solveSystemCylinder[]? It might make more sense stylistically and clarity wise to make Ei[p_,k_] a local function of solveSystemCylinder[] similar to t[x_]. Doing so doesn't appear to affect performance, but sometimes these kind of things can clarify one's approach to a problem.

comment How to get the distance of Jupiter from the sun?
@belisarius - Perhaps just slipping glimpses of parallel universes. More (or less given one's point of view) seriously, I ran the Wolfram Alpha query and your code and almost the same time and got essentially identical values (7.743 x^11 meters). I just ran The Wolfram Alpha query again and it comes out 7.744*10^11. Not as big a move, but a move.

comment How does Accumulate work?
I love knowing and trying to figure out what goes on under-the-hood, but as an intellectual property developer, I do feel an uncomfortable twinge at full-on reverse engineering. It makes me feel (just a little) like we've cheated on the love of our lives. That said, +1 for an interesting question.

comment Using mathematical notation
This question would benefit from some attempt to actually do this in Mathematica and Mr. Wizard's answer raises important issues. Still, I've up voted it, because trying this kind of thing helped my entry into the Mathematica universe. I think it could also help others. Not the most efficient way to use Mathematica, but interesting none the less.

comment Do Mathematica notebooks include personal metadata?
You can examine the entire notebook in a text editor to make certain it doesn't contain anything you don't want to include, but honestly, it will only have in it what you put in it.

comment data visualization on a lattice grid
+1 from me. Always nice to come across another devote of Tufte. It makes me optimistic that given enough time (and gentle promotion) we can find way to visualize the increasing complexity of the world in which we live.
