Automatic field should take the required entry How to create animated GIFs of prototype mockups, like the ones on Dribbble? I'm sure you've seen Dribbblers upload animated mockups of their designs.   Here's an example:     I can create mockups on Photoshop and even apply simple Tween Animations to them but I can never get my GIFs to look like the example here.   What are Dribbblers using to create these animations?   Notice that the animations also include touch points and perfect motion. I would like to convert my Photoshop mockups to do the same.  How can I create an animated example of my mockups, similar to the ones created by Dribbblers? No feedback when comment fails to post on Android 2.3.5 In the mobile theme on Android 2.3.5, comments that do not meet the minimum length will fail to post but no feedback message is displayed to the user.  The submit button changes to its active state, but nothing else happens. Traveling to the US with new passport, visa on the old one I have a valid B1/B2 US visa expiring about a year from now. The passport it's in expired a few years ago, and I recently got a new one.   The passport number does not match, but the national ID number, mentioned in both, does (it used to be the same as your national ID, but not anymore)  Can I travel to the US carrying both passports? Or is it asking for trouble? (I read a few years ago that it was possible, but that might have changed)  Should I just get a new visa to avoid potential complications? Korean characters scrambled [XeLaTeX; Noto Sans Korean]? I was trying to find a font which has obsolete jamo and the right combining behaviour. Yesterday I found out about , which seems to have both of these. However, when I use it in XeTeX, I get some seemingly-arbitrary hanja (or blank spaces) instead of the expected characters.  (I’m guessing the composing behaviour will fix itself when the right characters are selected. And yes, I know that Code2000 is working perfectly in this example, but unfortunately it is the ugliest font in the world. :p)  MWE:  \documentclass{article} \usepackage{fontspec}  % 1. precomposed: U+BB47 % 2. separate jamo: U+1106, U+116E, U+11BA % 3. obsolete [separate jamo]: U+113B, U+119F, U+11EB \newcommand\test[1]{#1 &amp; {\fontspec{#1}{뭇; 뭇; ᄻᆟᇫ}} \\}  \begin{document}  \begin{tabular}{rl} \test{Arial Unicode MS} \test{Batang} \test{Code2000} \test{Gulim} \test{GungSeo} \test{HeadLineA} \test{Nanum Brush Script} \test{Nanum Myeongjo} \test{Nanum Pen Script} \test{Noto Sans Korean} \test{PCMyungjo} \test{PilGi} \test{Adobe Gothic Std} \test{Adobe Myungjo Std} \test{Apple SD Gothic Neo} \test{AppleGothic} \test{AppleMyungjo} \end{tabular}  \end{document} After I installed Ubuntu 13.04, I can't mount my NTFS partition.

Setting READ UNCOMMITTED when reading DMVs I've seen several people call SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED before reading system DMVs. Is there ever any reason to do this, assuming you aren't mixing calls to DMVs and tables in the same transaction? How to toggle Scroll Lock in Excel 2010 without a Scroll Lock key in the keyboard I have a notebook with no Scroll Lock key (or any shortcut using the 'Fn' key).  Somehow Excel 2010 got the Scroll Lock on. I see it left down in the status bar and now I can't navigate through cells using the arrow keys, which is pretty annoying. It wasn't turned on some hours ago, so I think I must have hit some Scroll Lock toggle shortcut in Excel 2010 by mistake.  Anyone knows what hot to turn off Scroll Lock in Excel (shortcut or menu option)? Why do we have no enzyme to digest cellulose? As we know, cellulose is the most abundant polysaccharide in nature. Why don't we have an enzyme to digest cellulose? 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? Ubuntu 14.04, problem when install gstreamer1.0-libav, unmet dependencies Suddenly my Ubuntu stopped playing video. When I open a video, the player suggests that I install  gstreamer1.0-libav.

Female main character in an ice world earning gems/runes Here's what I remember:   The main character's female (99% sure) There is one part where she has to cross a big tundra and she has to kill a big ice creature The kids in the story go to a school-like place where they train for something. I'm pretty sure they earn gems or runes or something like that There's one part where the main character has to play a piece of music perfectly to earn her gem/rune thing It's definitely a series; young-adult (I read them in middle school)   Thanks! How do I install the Cinnamon Desktop? I have read that there is a new Gnome-2 like interface called Cinnamon produced by the Linux Mint developers.  Is this available for Ubuntu users - and if so how do I install it? Is full wave rectifier better than half wave one? What type of path in shebang is more preferable? Is this an equivalent formulation of "surjective" resp. "epimorphism"? What are these three references from episode 9? Separability over intersection of intermediate fields Let $E\mathop{/}F$ be a finite-degree normal extension of fields. Let $K$ and $L$ be intermediate fields (that is, $F\subseteq K\subseteq E$ and $F\subseteq L\subseteq E$) such that $E$ is separable over both $K$ and $L$. Show that $E$ is separable over $K\cap L$.   So I was thinking that if $f=\min_{K\cap L}(\alpha)$. Then $\min_{K}(\alpha)$ divides $f$. But if $f$ has repeated roots then I don't see what goes wrong.   Thanks! How to check if a string contains a substring in Bash The foreach identifier and closures
