How can I set the default terminal used in Unity?  I would like to use the Ctrl+Alt+T hotkey to start a non-default terminal. The default terminal is gnome-terminal.   Where can I change the default terminal value? Pokemon Egg Disappearing So my Pokemon eggs are reaching "maturity" then they just disappear. I don't get a new Pokemon. The egg just disappears. I had this happen with a 2k and a 5k now. Is this happening to anyone else? How many ways can N elements be partitioned into subsets of size K? I am having an access problem to some files and directories that I have tracked down to the group assigned to access them.    When I manually change the name of the group in the properties/permissions menu for a directory from the default setting (MyGroup) to www-data used by my Drupal Website, the directory error messages I get are gone.    There are a large number of files and directories that require this change.  If believe using chmod will change the owner which is set correctly and being new to Ubuntu, I am reluctant to experiment without a better understanding of how owner and groups work in the permissions settings.   What command changes the Group setting for a directory? System freezes completely with Intel Bay Trail How can I format a date as dd/mm/yyyy or mm/dd/yy ?   Like in VB format("dd/mm/yy",now)  How can I do this in C#? Best compiler warning level for C/C++ compilers? Adding the consensus to review's history I'm curious how USB device recognition works in Windows. I imagine it's something like this:   When you plug in a device, it tells Windows "here's my device ID to tell you what I am" Windows looks to see if any drivers have been installed that match that device ID. The driver probably tells Windows what the device should be called - like "BlackBerry Curve" or "Canon Printer" If so, it somehow associates that device with that driver Otherwise, it looks for a matching driver online (if you let it)   Am I right? If so, that still leaves some questions.   When you install drivers, where do they go? Are they files in a folder, or do they get added to the registry? What is Windows doing when it first recognizes the device, thinks, and finally says "your new device is installed and ready to use?" Where does Windows look for missing drivers? Is it in their own database? Do device manufacturers submit drivers to Microsoft for inclusion there?   Can anybody explain how this process really works? Also, do other OSes do this differently? rsync two existing directories copying everything I have two file servers in two locations. Currently both have the same data, which generally is unmodified (used for read only access).When the second server was set up (the one I'm sshing to) the data was copied over LAN and has since been moved geographically.  I'm trying to use rsync for the first time on the required directories. An example command;  sudo rsync -avz --ignore-existing -P --dry-run /media/Storage/OSs/ user@mydomain:/mnt/Storage/OSs/   I've tried using -c -t -u (Additionally went on the remote server and updated the timestamps to today) also but every time I execute a dry run it wants to copy everything!  Additionally the user is the same for both machines with the same UID.  *Edit  After playing around a bit more, I've found that rsync does not like the whitespace in the subdirectory names; For instance if I use ' to escape local shell &amp; \ to escape remote shell     sudo rsync -avz --ignore-existing -P '/media/Storage/OSs/Windows/Windows server 2011/' 'user@mydomain:/mnt/Storage/OSs/Windows/Windows\ server\ 2011/'   Then all is well, my theory is then that rsync does not like the subdirectories with whitespaces. I have thousands of subdirectories; the only solution I can think of is to write a small python/shell script to run each sub directory separately but is undesirable. I am confused by the behaviour of Currency fields in Multi-Currency environments. My app does a calculation on day X and stores its result in a record.  The custom page which displays a SUM of those values should always display the same as a database query. But...it does not. If I change Exchanges Rates those values change.  Was it wrong to store currency values in a Currency field, am I querying incorrectly or do I need to display a values that is manually calculated?  How does Multi-Currency and Currency fields work together? When are currency values converted and which conversion rate is taken into account?  I am confused?! Where does Google Chrome for Linux store user specific data? how to output text to both screen and file inside a shell script? Currently I have a shell script which logs messages to a log file like this:  log_file="/some/dir/log_file.log" echo "some text" &gt;&gt; $log_file do_some_command echo "more text" &gt;&gt; $log_file do_other_command   When executing this script, there is no output to screen, and, since I'm connecting to the server via putty, I have to open another connection and do "tail -f log_file_path.log", because I can't terminate the running script and I want to see the output in real time.  Obviously, what I want is that the text messages are printed on screen and into file, but I'd like to do it in one line, not two lines, one of which has no redirection to file.  How to achieve this? Working with objects created with Activator.CreateInstance I am trying to add a list into an another nested list before adding values of a list to nested list it is getting the correct value but after adding i am getting (already output) in debug log when i checked.    public List&lt;String&gt; fieldName {get;set;}  public List&lt;List&lt;String&gt;&gt; fileValuesXML; // To get the field values of xml  for(Dom.XMLNode child : SalesforceObjecet.getChildElements()) {                        objecetName = child.getText();             system.debug('Object Name in XML field  ' + objecetName );              for(Dom.XMLNode subchild : child.getChildElements())              {                 system.debug('Sub child ' + subchild.getText() );                 for(Dom.XMLNode subchildfield : subchild.getChildElements())                 {                     system.debug('Sub child Field ' + subchildfield );                     fName  = subchildfield.getText();                     fieldName.add(fName);                     //fileValuesXML.add(fieldName);                     //system.debug('Filed Name in XML field  ' + fieldName);                 }                  system.debug('Filed Name before affing to filevalueXML  ' + fieldName);                                     fileValuesXML.add(fieldName);                 fieldName.clear();                 system.debug('Filed Name after affing to filevalueXML  ' + fileValuesXML);             }    }    I am getting values in debug log as:     Filed Name before affing to filevalueXML  (AccountSource, field3)   Filed Name after affing to filevalueXML  ((), (already output),   (already output)) TikZ: Having circle borders only grown to the outside Is there any tweak to bring back emblems in Nautilus? Can newsletters take into account a user's ignored tags on that site? I have seen several questions that discuss using your "Favorite" tags to construct a newsletter.   I'm looking for a similar request - but for ignored tags.  I figure it might make sense to split this request from the "favorite" requests because it has different implementation.  Can we exclude questions on the "ignore" tags lists in the newsletter?   For example, I subscribe to the Board and Card Games newsletter.   Currently (and frequently) 6 of the 7 questions are about magic-the-gathering, a tag I have in my ignored list.     I now get a newsletter where at best 1/7 questions is interesting and worth clicking on.  Related questions about using "Favorites": Is a totally ordered set well-ordered, provided that its countable subsets are? Let $(X,⪯$) be totally ordered set, prove that if every non empty countable subset of $X$ is well ordered then X is well ordered.   It does seem obvious that any subset should have a minimum but I am not sure of how to prove it. Any help would be appreciated, and sorry I put up the same problem earlier but forgot to include the 'countable' subset. Background - I am doing my PhD in atmospheric physics/photobiology.  Here is a scenario:   The experiments are complete - the results are far better than expected  Successfully got the computer program to work properly and have developed another Papers are published Much of the thesis is drafted   The light at the end of the tunnel is most definitely no longer an oncoming train.  But, at this stage, you just don't feel like working on the thesis, you do other things like cleaning, reading, watching movies - procrastination gets worse, and worse despite the submission deadline coming closer.     The procrastination resulting in more apathy towards the project, despite being fully aware of how much work has been put into the project, how much has been achieved and how little, comparatively, needs to be done.  What strategies are there to overcome this academic-apathy, particularly in this late stage of the thesis?
