is stranding prepositions incorrect?
When is it appropriate to end a sentence in a preposition?
What can I actually do with a high credit score? I recently checked my credit score via two of my credit card providers. It seems to be hovering between 790 and 815. One service brands the score it provides as a FICO score and the other specifically says its score comes from Transunion.   What can I actually do to leverage this high credit score to my advantage?  The only new debt I might take on would be a small HELOC or car loan. Does a high score give me any negotiating power with the lender to get a better rate? Should I treat the score as a card in my hand or is it something I should show early in negotiations?  Does a high score make me eligible for any discounts on insurance?  Does a high score open up any options for earning more interest on savings accounts?  The typical advice I'm reading suggests refinancing a mortgage. That seems like good advice in general but it does not apply to my personal circumstances. I've got 3.5% on a 15 year note with 9 years left. A casual review of current rates suggest I could maybe scrape 0.5% off of that, hardly seems worth the effort and cost for half a percent. My 3 years old doesn't tell me when he needs to use the bathroom Is it okay to record audio for a lecture? Sometimes the Professor will say things quickly, or say things before I can write them down. It would be of great benefit if I could record audio for the course, but I am not sure the legal guidelines around doing so. How to make dried desert/cracked ground I am trying to create a cracked ground appearance for an animation that takes place in the desert. something like the image here:I would like to do this all in blender, and have blender generate the texture so I will not have to worry about unwanted ridges like those you would get in an image from the internet: I am wondering if there is a way to procedurally generate these cracks and use them with microdisplacements.

My flight goes from Vancouver to Manila via Tokyo Haneda. I will arrive in Japan at 6pm then depart at 9am the next day. I'm not planning to go out of the airport during my layover, so I don't see a need to have a transit visa. However, I called the Consulate-General of Japan here in Canada, and they asked me to get a transit visa.  Then I called the Ministry of Foreign Affairs in Japan and asked them the same question.. at first, they told me I don’t need a visa as long as I stay inside the airport, but when I told them that the Consulate-General of Japan in Canada asked me to get a visa, they also asked me to get one.  I'm so confused. I would like to know your knowledge or experience regarding this. How to find all graph isomorphisms in FindGraphIsomorphism What is the relativistic calculation of travel time to Proxima Centauri? It has already been  how fast a probe would have to travel to reach Alpha Centauri within 60 years.  NASA has done  into a probe that would take 100 years to make the trip.  But I am interested in this question from a slightly different perspective.  I would like to know how long the trip from our solar system to Proxima Centauri would take for both a ship and for an observer on Earth while accounting for the effects of general relativity on a .  The following assumptions may be made:   The ship starts and ends at 0 km/s relative to the Earth observer. The ship experiences a constant force of acceleration of 20 g until the half-way point and then a constant force of deceleration of 20 g until the destination. The path traveled is such that accleration is in only one spatial direction. The distance traveled is 4.25 light years.   Calculate (accounting for general relativistic effects):   Time of trip for Earth-based observer. Time of trip for ship-based observer. Maximum speed.   You don't need to consider mass, or life-support systems, or method of propulsion; I am really only interested in the effects of relativity on the perceived time of the trip. How can I add an item to the 'new' context menu? When I right click anywhere I get an option to add a new file with a specified extension.

What's the preferred method of writing AJAX-enabled plugins? Does the speed of light vary in non-inertial frames? The speed of light is the same in all inertial frames.  Does it change from a non-inertial frame to another? Can it be zero?  If it is not constant in non-inertial frames, is it still bounded from above? If a character is drunk, what are the penalties associated to it? Are there any benefits to it? I do remember a special prestige class for monks about it, but I don't remember anything specific in the core rulebook. shopt works in command line, not found when run in a script I'm writing a script to copy some files around, and trying to use shopt -s dotglob  like .jshint and whatnot.

Atheros AR9462 WiFI very unstable & package loss I'm having severe issues w/ package-loss and a generally bad connection w/in a WiFi-network at my uni. I'm usually encountering a package loss of ~50% and aborting connections which makes working w/ SaaS impossible.  I'm using Ubuntu 13.04 and my network-adapter is an Atheros AR9462.  Applying the nohwcrypt=1-option doesn't change anything.  Also very noticable: The connection works as intended in other networks; the problematic network uses WPA2 w/ MSCHAPv2.

How to reduce the thickness of letters Is there a noun that doesn't have a plural in any of its forms? While attempting to answer  @ProgramFox has been trying to come up with an example of a noun with no plural.   The best I've come up with is egotism and Judaism.  ()  Some of the contenders I've already shot down are air, water, and money.  (Airs, waters, and monies are all legitimate plurals.)  My question is, a) Do my two examples have actual plurals?  b) Are there any other non-ism nouns that don't have a plural? pylab.ion() in python 2, matplotlib 1.1.1 and updating of the plot while the program runs Sum of a Hyper-geometric series.
