unable to install synaptic package manager
Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?
Is there a way to save composite node presets? Is there any way in Blender to save settings in your compositing node setup. For example say for my shadow catcher I have it setup for a hard shadow for sunlight, and then I also have a setting for diffuse light shadow for indoors. Is there any way I can save these settings individually so I can quickly switch to them rather than having to individually change the nodes every time. How can I get numbered classes on rows? I worked briefly with Drupal 7 and I thought it was possible there but in Drupal 8 is it possible to have a view output an increasing numbered CSS classes for Views rows?  This is what I want.  &lt;div class="view"&gt;   &lt;div class="view-row-1"&gt;&lt;/div&gt;   &lt;div class="view-row-2"&gt;&lt;/div&gt;   &lt;div class="view-row-3"&gt;&lt;/div&gt;   &lt;div class="view-row-4"&gt;&lt;/div&gt; &lt;/div&gt;   I know I can add a CSS class to every row and give every row the same class. While the etiquette of dealing with duplicate answers , there hasn't been a great way to deal with these, "Uh, yeah, I said this, too" types of behavior than the almighty downvote.   It would be nice to have a "Duplicate Answer" option on the flag menu. Five flags auto-deletes the answer, as with any other flag. In order to prevent abuse, the flagged answer would have to have the last owner edit (including original post) be younger than the original answer's original posting by at least 2 minutes.  Also, this ability should be a 5,000+ rep privilege, since we currently have no fanfare of rep from 3,001 to 9,999, and a power like this has a bit more umph than closing a question.  Thoughts? Whoever or whomever: 'happy for ___ has the pleasure of working with you next.' So sad to lose you, yet happy for whomever has the pleasure of working with you next. A similar task for changing the desktop background, can be achieved using the following script:   FILE="/backgrounds/background.png" gsettings set org.gnome.desktop.background picture-uri "$FILE"   How would I achieve the same result, but with the user's avatar/profile picture? If H is a subgroup of G ( | G:H |=n, n > 1), then how can you show that G has a factor group G/N which is isomorphic to a subgroup D of the symmetric group Sn with |D| > 1.  I've been looking at Cayley's Theorem but it's not specific to the factor groups. Is it possible/sensible to add a suspension fork to an old mountain bike? I have a ~1993 Giant mountain bike.  It's not great, but I am a very new and casual rider.    The bike has a solid fork and it makes for the predictable rough trail ride.  The trails are generally fairly modest (I live in North Texas, a 100' change in altitude makes our ears pop here) and the surface is generally dirt (very few rocky areas).  So, I am thinking that it would be very nice to have a suspension bike.  And seeing that a modest fork can be purchased for a modest price, I am wondering if it makes sense to add a fork to this bike.   asked about going the other direction, and there were some cautionary words about changing steering geometry.  So, on balance, is this something that I would be best off to avoid?  I suspect that if I have to replace a bunch of steering parts, the cost will quickly approach that of a new low end bike. How to define a command that takes more than 9 arguments I have a mathematical transformation that takes 16 parameters (grouped into 3+8+5) and would like to make a latex command for it, so that I can easily change the notation for it if the need arises.  As far as I know, both \def and \newcommand take a maximum of 9 arguments, is there any (recommended) way to extend this? Changing planes at Newark Airport I fly in from Sweden with United to Newark Liberty Airport. The connecting flight with United departs to Costa Rica a few hours later from Newark as well. The two flight-segments are part of the same trip and ticket.  I was hoping to stay in the same terminal but am suspecting that it wont be as straightforward as I had hoped - reading through the older posts it seems that a transfer is needed from A to C but it's not fully clear.   Do I need to pass through immigration? Do I need to fetch our bags? Even if my bags have tags all the way to SJO? Do I need to change terminals? Which terminal would I arrive in? Depart from? We are doing research on monitor human activities to avoid adverse events. In part of it, we did an experiment in our MoCap lap to detect the human motion to monitor his activities. We have f-curves from that motion. But we need all the xyz coordinates values for that motion for that given time (just say about 2-3 minutes) to do a scientific analysis of the data.  Do anyone have an idea how to get xyz values from f-curves? Restore SQL Server 2012 backup to a SQL Server 2008 database? Unexpected output for this following code I know there are many ways to prevent image caching (such as via META tags), as well as a few nice tricks to ensure that the current version of an image is shown with every page load (such as image.jpg?x=timestamp), but is there any way to actually clear or replace an image in the browsers cache so that neither of the methods above are necessary?  As an example, lets say there are 100 images on a page and that these images are named "01.jpg", "02.jpg", "03.jpg", etc. If image "42.jpg" is replaced, is there any way to replace it in the cache so that "42.jpg" will automatically display the new image on successive page loads? I can't use the META tag method, because I need everuthing that ISN"T replaced to remain cached, and I can't use the timestamp method, because I don't want ALL of the images to be reloaded every time the page loads.  I've racked my brain and scoured the Internet for a way to do this (preferrably via javascript), but no luck. Any suggestions? How should we treat questions that are, or have seeds of, evil or malicious purposes and actions, such as writing spambots and malware?    Should they be answered like regular "everybody keeps their pants on" questions? Or should there be some other type of response to this bad behaviour lot? I am trying very hard to install Canon LBP2900b Printer in Ubuntu 13.10.  I have searched and googled a lot for the solution over fortnight but none of the site / link gave me the simple solution for me. How can accomplish my goal? How to close view windows? I would like to close some view windows that I opened accidentally.  See the image below:    Edit: another note: I tried searching for the solution, but only found things like "Join Area", which don't seem to work in this situation. Help! My party isn't challenged? While I've been running my campaign, I'm starting to get stumped. I am playing with a party of four, and we recently switched from 3.5 to Pathfinder, but the problem was the same in both situations.  No matter what I throw at the party, they seem to have no problems. Even if I put them up against something that is supposed to be 'Epic' or 'overwhelming' in terms of CR, they make out just fine. The one exception to this is when I had several encounters in one day that taxed them to near death. Usually I have about two encounters a day, but that day I had four encounters, with two of them being APL+1 and the other two being APL+2, and that was challenging. But other than that nothing seems to faze them!  How can I make the game more challenging without making it harder?  Just for reference, the party is fairly standard, and low level (level 4):   Wizard (tends to resort to mind-affecting spells, or grease if the creature is immune) Cleric (heals a lot, but always has spells / healing left over) Rogue (sneak attack, of course, which is more potent in Pathfinder) Fighter (gets enlarged and in-charge'd) What is the solution to the following recurrence relation with square root: $T(n)=T (\sqrt{n}) + 1$? Why do you write "occurred" but "listened"? The past tense of to occur is occurred (not occured), but the past tense of to listen is listened (not listenned).  Why? What is the general rule that is applied to make the past tense of a verb? First post and late answer review queues always empty?
