Prove that if every node in a simple graph $G$ has degree $3$ or higher, then $G$ contains a cycle with a chord. Custom Tools not Saving in Toolbar on Startup/ Normal.mxt? I am trying to save some tools that I have created into the default toolbar layout that is present when ArcMap 10.1 is launched.  It is possible to change the arrangement of toolbars, add new ones and even add in existing tools, but any custom tools I set in the commands category "geoprocessing tools" are gone and do not appear in the toolbar. How can I save these custom tools to the default layout that appears on startup?  Update:  Saving a document with the custom tools added and reopening it preserves the tools, but opening a template (10.1 mxd) containing the tools, then opening and older document will cause the tools to disappear. Oddly enough, any other changes made after the custom tools were added are preseved.  Update (03/18/2014):  I have upgraded to 10.2 and this has still not been fixed. I did not see this issue in the 10.21 changelog so I doubt it will address it. For those interested in this issue, I have started a forum post on the ESRI forums .

Wordpress speed slow after .5 million single image post via wp-cli There was a foolish (in my opinion) question asked on Scifi.SE       James bond keeps returning with a different face, albeit usually a similar one, and often operates with high-tech gadgetry that seem to be on par with the Doctor's sonic screw driver.   In my opinion each new actor represents a reboot of the franchise using the new face, not a continuation of the story.   Is there any continuity between versions of James Bond which change actors? I'm not talking about characters like M or Q, I'm talking about events or past advisories being referenced in a different Bond movie where the main actor was someone else. I currently trying to join two rigged (and animated) models, which both has separate meshes, separate bones and separate animations. The first mesh is the horse while the second mesh is human:   So I am interested to join human model onto horse model to make a rider:   I think the best way would be to make horse as a parent and human as a child during the join process. In that case I would like that all horse animations (there are 3 of them - idle, walk and run) would remain as they are, while I can lose human animations, as I will need different ones for it. I was also thinking to make human root bone as a child of one horse back bones, that when horse moves up and down it would move entire human mesh together. It would be also good to keep the same weights that human bones would not start deforming horse mesh and vice versa.  I tried to use Ctrl+J by selecting various combinations between bones and meshes in object mode, however, I noticed that it messes up scaling and rotation of the child object. So I was wondering how it would be possible to properly join these models to create a rider? 90s (or earlier) Japanese anime movie: two planets at war, young man is in love with princess from the other planet, and floods his own village In this movie there are scientists who (spoilers ahead)       ...are creating a simulation. One scientist starts seeing odd looking characters but no one else sees them. He asks around and more and more characters are missing or don't know about the characters in the story he knows about.  He finds out that he is part of a simulation. He finds out that the characters only he remembers have been deleted. He also finds out that there are characters from his own simulation that have broken free of his simulation and are in his world.    Hints: I remember this being an older film (70's?); it might have been foreign film possibly with subtitles (not Hollywood); it might have been part of the Criterion collection; I'm pretty sure I streamed it from Hulu.

How can I mount a flash drive manually? What should be the copy command? How to make ssh log in as the right user? I use ssh on a variety of machines, mainly linux. Accounts on these machines vary in naming scheme: if my name is First Last, then I have accounts: first, flast, last_f, lastf, and sometimes I need to log in as root. For each machine I use, I would like the openssh client to know which account to use when I don't specify on the command line.  So the question is: How do I make ssh server Do The Right Thing when a username is not specified? I use pgfplots for most of my plots. Now I need to add a .

I have a .NET 2.0 WinForms application with a ToolStrip on my main form. Sometimes, the ToolStrip icons don't respond to the first mouse click, so I have to click the icon twice.

How do I apply a gradient across multiple objects in Illustrator? I have two separate objects that I have applied gradient fill to.  The gradient fill seems to only apply to the objects as individuals. I tried grouping the shapes, but that doesn't seem to change the gradient.    How do I get one gradient to cover all my shapes? How to use "tens of" and "hundreds of"? If I'm not mistaken, tens of means 10 to 99 and hundreds of means 100 to 999. Is this correct? I found in some dictionaries that tens of is actually not correct.  I also found that hundreds of could also mean any arbitrary large number. So how would people usually interpret hundreds of? Based on context?  In my case, I want to describe numbers of some items that are usually 50-90 but sometimes could be around 100-200, but definitely not as many as 300 or so. I want to really emphasize that there are a lot of these items. In this case, can I say "... have tens or even hundreds of ..."? Would people misinterpret what I actually want to say?
