Ok I don't know if I'll explain this properly. I have no idea what I've selected to make this happen but it's messing with my head. In my current project I cannot move a mesh in Object mode, I need to be in edit mode. If I duplicate in object mode using shift D it seems to add a new mesh, but I can only move the visible Move icon. I have no idea what this is option/function is for. See image below:  If a create a new project with a mesh, I can move the mesh by pressing G. Or when I press shift D it immediately moves the duplicated mesh and can be moved as below:  What on earth have I done? I've searched through all the menus I can think of I don't know what option I've selected to make this happen, but I don't like it. Appreciate any help with this.
I can only move the origin point of the mesh that I selected in object mode, but not the whole mesh Did I set anything up by accident?
How do I right align controls in a StatusStrip? I have got the Client Cross Frame Scripting Attack alert in the recent CheckMarx scanner. However, it points to an auto generated ID.   I've seen the following links however, the I'm not sure about relavancy of the soluions given i.e.,          Regarding my visualforce component, I'm doing just one DML operation on a custom setting from a callout response. Also, I'm not passing any attribute to the component.   To give a background of the component, its just a list view of records from a different system retrieved through a callout on load via JavaScript.  Let me know if in case anything else is needed.   Thanks in Advance! Peace! Smoothing polygons in contour map? Here is a contour map for which all the polygons of levels are available.  Let ask how to smooth the polygons keeping all vertices preserved in their exact locations?    Indeed the contour is made on top of a grid data, you may suggest then to smooth the grid data and hence the resulting contour will be smoother. Note that this is not working as my desire since the smoothing function such as Gaussian filter will remove small packs of data and will change the range of the third variable e.g., the height which are not allowed in my application.    Actually I'm looking for a piece of code (preferably in Python) which can do the smoothing of 2D polygons (any type: convex, concave, self-intersecting etc) reasonably painless (forget pages of codes) and accurate.   FYI, there is  that does this perfectly, but using third party commercial applications is not my choice for this question.        1)    Scipy.interpolate:        As you see the resulting splines (red) are not satisfactory!  2)    Here is the result using the code given in . It is not working well!      3)    To me the best solution should be something like the following figure in which a square is being smoothed gradually by changing only one value. I hope for similar concept for smoothing any form of polygons.       Satisfying the condition that spline passes the points:     4)    Here is my implementation of "whuber's idea" line by line in Python on his data. There are possibly some bugs since the results are not good.         K=2 is a disaster and so for k>=4.   5)    I removed one point in the problematic location and the resulting spline is now identical to whuber's. But it is still a question that why the method does not work for all cases?        6)    A good smoothing for whuber's data can be as follows (drawn by vector graphics software) in which an extra point has been smoothly added (compare with update   4):      7)    See the result from Python version of whuber's code for some iconic shapes:     Note that the method seems doesn't work for polylines. For the corner polyline (contour) green is what I want but got red. This needs to be addressed since contour maps are always polylines although closed polylines can be treated as polygons as in my examples. Also not that the problem emerged in update 4 has not been addressed yet.  8) [my last]    Here is the final solution (not perfect!):        Remember that you will have to do something about the area pointed by stars.  There is perhaps a bug in my code or the proposed method needs further development to consider all situations and to provide desired outputs. Solving "MySQL server has gone away", mysql error 2006 I have a site at hostgator, using their "Business account". It's cheap, and comes with a private SSL cert. HOWEVER, their MySQL settings are such that any db connection goes stale fairly quickly, and then the hostgator staff try to convince you to use a VPS or dedicated server at multiple times the expense.  I'm creating and deploying WebAPIs, which can have a 'conversation' which exceeds 60 seconds. When this occurs, the db connection handle is stale, causing any db operations after my timeout to fail.  I'm in the process of implementing the following solution, but am curious if anyone else has solved this issue (where they can not modify their my.ini or my.cnf to give MySQL more resources) in a similar or completely different manner.  last part of a hook_update:  $ret = db_query( "UPDATE {my_table} set field1 = '%s', field2 = %d ... WHERE vid - %d", $node-&gt;field1, $node-&gt;field2, ... $node-&gt;vid ); if (!$ret) {        // get private storage directory for this node:        $cexStorage    = _cex_front_getCexStore();        $nodeFilesPath = DRUPALROOT.'/'.$cexStorage.'/'.$node-&gt;storeDir;        $fname         = $nodeFilesPath.'/recover.node';         $readyToWrite  = serialize( $node );        file_put_contents( $fname, $readyToWrite );        if (file_exists( $fname )) {          _dbgReport( 'seems to have worked!' );        }     }   Then this is called in my hook_form, right after I determine that node->nid is valid:  function _cex_front_recover_node( &amp;$node ) {   if (!isset($node-&gt;storeDir)) {      _dbgReport( '**************************** _cex_front_recover_node: no storeDir!!!' );      return;   }    // get private storage directory for this node:   $cexStorage    = _cex_front_getCexStore();   $nodeFilesPath = DRUPALROOT.'/'.$cexStorage.'/'.$node-&gt;storeDir;   $fname         = $nodeFilesPath.'/recover.node';   if (file_exists( $fname )) {     $recovered = file_get_contents( $fname );     if ($recovered) {       // no longer needed:       unlink( $fname );       $recoveredNode = unserialize( $recovered );       // restore the key values I need to proceed with this node:       $node-&gt;stage = $recoveredNode-&gt;stage;       $node-&gt;rnid  = $recoveredNode-&gt;rnid;       $node-&gt;iris  = $recoveredNode-&gt;iris;       cex_front_update( $node );     }     else {       _dbgReport( '********* failed to read "'.$fname.'"' );     }   } }   I'll be pairing the logic down to only store the key fields I need, but this works! Sure beats upgrading my server at 3x the expense. Anyone else doing something like this? Installing opencv I've downloaded opencv but unfortunately I've got no idea how to install it. All the pages I found online were only telling me how to download and install it directly from the console, not what to do when you already have it downloaded. Could anybody tell me what to do? I'm playing around with height maps (bitmaps), trying to create some of my own in my game, and for that I need to implement some basic drawing methods. I've quickly realized that drawing straight lines isn't as basic as I thought.  It simple's if your points share an X or Y coordinate, or if they are aligned so you can draw a perfectly diagonal line. But in all other cases its trickier.  What algorithm do you use to determine what pixels need to be coloured for it to become a "straight" line ? No margins for Winter Bash popup When opting out the Winter Bash the top bar popup related to snowflake looks like this for me:    Is it intentional that there are no horizontal margins for popup content? I've just started playing with Guice, and a use-case I can think of is that in a test I just want to override a single binding.  I think I'd like to use the rest of the production level bindings to ensure everything is setup correctly and to avoid duplication.  So imagine I have the following Module  public class ProductionModule implements Module {     public void configure(Binder binder) {         binder.bind(InterfaceA.class).to(ConcreteA.class);         binder.bind(InterfaceB.class).to(ConcreteB.class);         binder.bind(InterfaceC.class).to(ConcreteC.class);     } }   And in my test I only want to override InterfaceC, while keeping InterfaceA and InterfaceB in tact, so I'd want something like:  Module testModule = new Module() {     public void configure(Binder binder) {         binder.bind(InterfaceC.class).to(MockC.class);     } }; Guice.createInjector(new ProductionModule(), testModule);   I've also tried the following, with no luck:  Module testModule = new ProductionModule() {     public void configure(Binder binder) {         super.configure(binder);         binder.bind(InterfaceC.class).to(MockC.class);     } }; Guice.createInjector(testModule);   Does anyone know if it's possible to do what I want or am I completely barking up the wrong tree??  --- Follow up: It would seem I can achieve what I want if I make use of the @ImplementedBy tag on the interface and then just provide a binding in the test case, which works nicely when there is a 1-1 mapping between the interface and implementation.  Also, after discussing this with a colleague it would seem we'd head down the road of overriding an entire module and ensuring we have our modules defined correctly.  This seems like it might cause a problem though where a binding is misplaced in a module and needs to be moved, thus possibly breaking a load of tests as bindings may no longer be available to be overriden. Any nice, stable ways to keep a window 'Always on top' on the Mac? I am looking for a stable way to keep any window 'always on top' on OSX.  , an app that does that requires SIMBL/easySIMBL, which it seems is not very stable.  Are there any better solutions? It's actually surprising that there is no native way to implement this. Why True/False is capitalized in Python? All members are camel case, right?

I am able now to browse to  and it is asking in firefox to add some exception which is totally normal if i did not buy any certificate.  But I was wondering where it is set up that it should use the certificates in /etc/apache2/ssl/ directory. I can not find any config where it is told to use that. I all the time was thinking that it will use something from /etc/ssl folder.   Or did I maybe not activate SSL correctly? How do I call a .NET assembly from C/C++?

Stack Exchange app iPhone X optimization The Stack Exchange app doesn’t look very good on Apple’s brand new flagship phone yet.    Also the app can’t identify the device model either. (Says Unknown (iPhone 10,3))   App Version: 1.6.6.2 Device: iPhone X (iPhone10,3) OS Version: Version 11.1 (Build 15B93) Booting a Windows 7 installation on different hardware I'm in a situation where I could do with very quickly migrating a Windows 7 (RTM x64) installation from one machine to another.  What options are open to me in terms of getting W7 to boot after the drive is picked up and moved from one box to another? I thought it was supposed to be a little less sensitive to this kind of move than XP, but it doesn't work - it is stuck in a reboot loop and never reaches a GUI.  Tried a few things so far, none of which have worked:   Changed SATA mode in the BIOS of the target machine between ATA and AHCI run Windows 7 Startup Repair tried safe mode, no change   (I will keep this list up to date as suggestions come in)  UPDATE: I can confirm this reboot loop is due to STOP error 0x0000007B, and these codes follow:  0xFFFFF880009A98E8 0xFFFFFFFFC0000034 0x0000000000000000 0x0000000000000000    UPDATE: I didn't get anywhere on this and I ended up just rebuilding the machine. I think it should be theoretically possible, so I'm going to leave the question open in case someone comes along in future with an answer. Change paper size in mid-document My document should be letterpaper and my attachments should be a4paper. I had high hopes for the \newgeometry command from the geometry package, but the documentation says      \newgeometry is almost similar to   \geometry except that \newgeometry   disables all the options specified in   the preamble and skips the   papersize-related options: landscape,   portrait and paper size options (such   as papersize, paper=a4paper and so   forth).   Any help is appreciated! Boot stuck at logo screen after upgrading to 14.10 Name of mean absolute error analogue to Brier score? Yesterday's question  got me curious about probability scoring.
