What is preventing my objects from moving smoothly? Instead of moving slowly and precisely, the object moves by one unit    .
My cursor is moving by every selection by large increments!  Normally when I use Blender, I am able to select and move objects to any coordinate. Now, all of the sudden, when I select an object or mesh the selection moves by an inch or so in each direction.  How do I reset it to normal?
A complete residue system from an arithmetic progression I'm solving a problem, and the solution makes the following statement: "The common difference of the arithmetic sequence 106, 116, 126, ..., 996 is relatively prime to 3. Therefore, given any three consecutive terms, exactly one of them is divisible by 3." Why is this statement true? Where does it come from? Is it generalizable to other numbers? .bash_history does not update in Git for Windows (git bash) Is there any text editor which supports Markdown (Ask Ubuntu's formatting style)? I'm trying to prove commutativity of addition for vector spaces, using the axioms for vector spaces. Apparently commutativity can be proven! Im having trouble getting a good feel for what is allowed and what is not. Here's my work so far:  $u+v+u+v = 2(u+v) = 2u + 2v = u+u+v+v = u+(u+v)+v$  Here I just wanna claim that $u+(v+u)+v = u+(u+v)+v$   $\Rightarrow -u+u+(v+u)+v+(-v) = -u+u+(u+v)+v+(-v)$ : here im just adding -u to the right, and -v to the left. Question: is this "adding to both sides" really legit in this context? Why?   Quick help proof: $-v+v = (-1)v+(1)v = (-1+1)v = 0v = 0 = v-v$  And another: $ 0+v = v+(-v) + v = (1)v + (-1)v + v = (1-1)v + v = v = v+0$  We have $0 + (u+v) + 0 = 0+(v+u)+0 \Rightarrow u+v = v+u$  This feels ugly and not at all elegant, especially the great leap "add -u to both sides" feels completely out of place. Do I need more lemmas? Is there a more elegant way?   //not homework or anything, just for my own pleasure, feel free to provide theory, as it is more insightful than solutions. :) Thanks!   EDIT: corrected notation a little. Is there a way I can share the 3.42 GB download of Windows 8.1 from Windows Store? Stop inserting hard line-wraps in blockquotes! When you use the markdown editor's blockquote feature (the quote button / Ctrl+Q), it inserts hard line-wraps in the markdown source automatically for you. That is, it transforms text like this:  Hindus regard it as an earthly manifestation of the goddess Tulsi, a consort of the god Vishnu.   The offering of its leaves is mandatory in ritualistic worship of Vishnu and his forms like Krishna and Vithoba.   Into text like this:  &gt; Hindus regard it as an earthly manifestation of the goddess Tulsi, a &gt; consort of the god Vishnu.  &gt;  &gt; The offering of its leaves is mandatory in ritualistic worship of &gt; Vishnu and his forms like Krishna and Vithoba.   The editor should instead transform it into this:  &gt; Hindus regard it as an earthly manifestation of the goddess Tulsi, a consort of the god Vishnu.  &gt;  &gt; The offering of its leaves is mandatory in ritualistic worship of Vishnu and his forms like Krishna and Vithoba.   That is, without adding any newlines.   Why on earth does it insert hard line-wraps!? Both these forms look the same when rendered, but the current way makes it more difficult for us to go back and edit the blockquoted text later if need be.   This is particularly objectionable functionality for sites that use MathJax - while the hard line-wraps don't impact the rendered output, the additional &gt; that are inserted do (they manifest as greater-than signs if they get inserted within MathJax $$...$$). See this post on Meta.Math.SE for more details: .    I found  that this behavior is apparently :      The "reflow the text when you click blockquote" is a deliberate feature, intended to improve the readability on quoted text.   Seriously? Are there any browsers that don't soft-linewrap textareas anymore? How is hard-wrapping at 70(?) characters better than soft-wrapping at $textareawidth? If readability is the concern here, then why not hard-wrap all non-code upon post submission? Looking for Scifi Short Story in a Jerry Pournelle edited Anthology I'm looking for the title of the short story, and any of the volumes of anthology it may have appeared in. I know for SURE it's in one of Jerry Pournelle's anthologies, either Star Empires and There will be War, but as I have all the eBook version of THere will be war, I'm almost certain it wasn't there.   Anyway, the book is about a Commodore who went back to the academy to visit. I'm not sure what his name was, but I'm pretty sure he lived at "Mercer Hall". He had 2 roommates, and a butler to take care of all their needs, like putting away their stuff. (He even tried to argue with the hall monitor) The butler once took away their bottle of booze UNTIL they study for mid-term, and only gave it back AFTER they wrote to their mother AFTER the exam.   The book also goes heavily into "Bless you!" or the translated version, "May the great cosmic magnificence be benevolent toward you" or something like that. Basically, it's about as inoffensive as possible, and if you say it enough, and the aliens are reasonable, they will give up and things will resolve peacefully.   My Google-fu is weak and I can't find this particular story, or which volume of anthology was it in.   Little help? Can I use Wilcoxon Signed-Rank Test to test pairs of data in a time series? I have a dataset of measurements (non-normally distributed). Each line of this dataset is composed of two measurements of the same variable at a specific time (i.e. XYY [time, meas1, meas2]). This dataset contains 24 lines.  Is it correct to use the Wilcoxon Signed-Rank Test to compare these two measurements? Is it correct to use this test to compare the mean value of these measurements between different experiments?  Thanks How long can cooked food be safely stored at room/warm temperature? In-universe explanation for single line of planetary entry/departure in Star Wars Why are planetary blockades confined to a single point of a planet instead of being sphere shell shaped around the planet? (I know, it would take an awful lot of spaceships.)  Also, when a rebel ship wants to escape from a planet and there is a single star destroyer hovering in the atmosphere (or some more of them further up, like in the Empire Strikes Back) how come it's not a viable maneuver to fly low altitude for a couple of hundred kilometers horizontally (they would be out of the single-point blockade), then make a vertical dash upwards? I know I can set the render border with Ctrl+B and dragging a box.  But is there  a way I can exactly specify the border dimensions? What did Bill do to make Hanzo mad? I use Chrome as my main browser.  I also spend a lot of time on a particular webapp that my company uses.  I'd like to keep those two things separate.  I can run the webapp in a separate window - but I'd like to go further than that.  I'd like to have it be identified by a different task in the Win 7 taskbar; ideally a different icon; and ideally a different title in Process Monitor.  How can I run a second, independent instance of Chrome, with a different title and icon, that won't merge with my main Chrome browser. What harm can be done with a copy of one's passport? "exec: gnome-session: not found" when logging in using lightdm On login the password is accepted but I'm returned to the login screen. Tried multiple times even after reboot... same behavior.  I left my laptop (Lenovo Ideapad z510) in suspend mode (lid down) last night, but it did not resume this morning, as it usually does. It had shutdown or crashed, and on booting with Ubuntu the login failure mentioned above started.  cat ~/.xsession-errors /usr/sbin/lightdm-session: 1: /usr/sbin/lightdm-session: ls: not found /usr/sbin/lightdm-session: 104: exec: gnome-session: not found   Okay. I've tried a bunch of suggestions from    Changed id to /usr/sbin/id in /etc/profile removed .Xauthority removed /tmp removed,  purged and re-installed lightdm checked .profile for syntax errors (source .profile worked fine, so I guess no syntax errors)   Nothing worked. My guest login is working fine, so another user should also work. I'm now going to create another user and continue working, but a solution to this problem is still warranted... it's likely going to repeat in future.  Installing and reconfiguring gdm also did not work.  sudo apt-get install gdm SaveAsActivity is not allowed with whatId that is not supported as a task whatId What does it mean for two objects to "touch"?
