How to add a guest account without a password?
Age from Date of Birth using JQuery I need to calculate if someone is over 18 from their date of birth using JQuery.  var curr = new Date(); curr.setFullYear(curr.getFullYear() - 18);  var dob = Date.parse($(this).text());  if((curr-dob)&lt;0) {     $(this).text("Under 18"); } else {     $(this).text(" Over 18"); }   There must be some easier functions to use to compare dates rather than using the setFullYear and getFullYear methods.  Note: My actual reason for wanting to find a new method is length of the code. I have to fit this code into a database field that is limited to 250 chars. Changing the database is not something that can happen quickly or easily. Controlling colors of points in ListPlot "Unable to connect to Upstart" error when installing git-all I am using 15.04.   So I'm working with git and I installed the standard version. I set up the ssh keys and was able to clone one of my repositories to the correct folder. Everything was working great and then I decided it was a good idea to install more packages. I ran sudo apt-get install git-all. I'm looking at error codes now having to deal with upstart.  start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused No apport report written because the error message indicates its a followup error from a previous failure. dpkg: error processing package runit (--configure):  subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of git-daemon-run:  git-daemon-run depends on runit; however:   Package runit is not configured yet.  dpkg: error processing package git-daemon-run (--configure):  dependency problems - leaving unconfigured Errors were encountered while processing:  runit  git-daemon-run E: Sub-process /usr/bin/dpkg returned an error code (1)   This is what happens when I even update/upgrade my system. At this point all I'm looking to do is be able to install software and update my current software. Is there any way I can potentially reverse this issue or at least correct it?   Edit: Thankfully this issue was solved only a day or two after it happened. The accepted answer worked perfectly and took care of my issue Connect Error (2054) - mysql_old_password issue still not solved How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE? I want to install Oracle's JRE and to update to the latest version with the Software Updater when they released. Is there a Ubuntu package that is provided by Canonical or Oracle?  Before release Java 7, I followed  to install Java 6.  But it doesn't work for Java 7. There is no package sun-java7-xxx. How can you install Java 7? Does "non-" prefixed to a two word phrase permit another hyphen before the second word?  If I want to refer to an entity which is defined as the negation of another entity by attaching "non-" it seems strange to attach the "non-" only to the first word when the second one is really the word naming the entity. For example,     non-control freak   looks like a person obsessed with not being in control rather than one who is simply not obsessed with control.     non-control-freak   actually looks better because the "freak" is attached to the "non-" as much as it is to "control-", without the space implying the presence of a phrase break.    and its answers make it sound like totally detaching the "non" could be an option, but if I were following the convention of hyphenating "non-" could I add a hyphen after the next word to resolve this problem? Sending `time` command into text file I want to get the result of time command into a text file but it's not working it only put blank space in the text file.  I already tried this commands,  A-  $ x=`time` $ echo $x &gt; log.txt $ cat log.txt  $   B-   $ time &gt; log.txt  real    0m0.000s user    0m0.000s sys     0m0.000s $ cat log.txt  $   C-  $ time &gt; log.txt 2&gt;&amp;1  real    0m0.000s user    0m0.000s sys     0m0.000s  $ cat log.txt  $    What I really want is this.   $ time &gt; log.txt $ cat log.txt  real    0m0.000s user    0m0.000s sys     0m0.000s Which is correct, and why?     some days we went on adventures — him maneuvering our scooter, me resting my chin …   or     some days we went on adventures — he maneuvering our scooter, I resting my chin … Area 51 is miscounting my proposal followers I know of one person who is following my proposal who doesn't show up on the proposal webpage.    My proposal is for quantitative finance: .  It shows 19 people following the proposal (on the side of the page), and the total listed at the top of the page is 19 followers.  Yet one user is not listed: .  This makes me wonder if other followers are also not being counted? If I have an IEnumerable like:  string[] items = new string[] { "a", "b", "c", "d" };   I would like to loop thru all the pairs of consecutive items (sliding window of size 2). Which would be   ("a","b"), ("b", "c"), ("c", "d")   My solution was is this       public static IEnumerable&lt;Pair&lt;T, T&gt;&gt; Pairs(IEnumerable&lt;T&gt; enumerable) {         IEnumerator&lt;T&gt; e = enumerable.GetEnumerator(); e.MoveNext();         T current = e.Current;         while ( e.MoveNext() ) {             T next = e.Current;             yield return new Pair&lt;T, T&gt;(current, next);             current = next;         }     }   // used like this :  foreach (Pair&lt;String,String&gt; pair in IterTools&lt;String&gt;.Pairs(items)) {     System.Out.PrintLine("{0}, {1}", pair.First, pair.Second)  }   When I wrote this code, I wondered if there are already functions in the .NET framework that do the same thing and do it not just for pairs but for any size tuples.  IMHO there should be a nice way to do this kind of sliding window operations.  I use C# 2.0 and I can imagine that with C# 3.0 (w/ LINQ) there are more (and nicer) ways to do this, but I'm primarily interested in C# 2.0 solutions. Though, I will also appreciate C# 3.0 solutions. I created a bunch of filters in Gmail for a "master account" that receives forwarded mail from all of my accounts.  The filter list and web of labels/folders has grown to be rather long, and therefore a bit burdensome to manage. I would like to edit / delete / consolidate a lot of these filter rules (and folders) but it seems the only way I can interface with them is through the laundry list at Setting/Filters. It'd be cool there was an option to "View/Edit Filter" on an individual email's page, but I'm not sure if something like that currently exists.  What's the best way to view a filter rule currently being applied to an email (in Gmail)? Lookup list dependant on the contents of another cell hope someone can help to crack this one?  I've got a table on my data entry tab (sheet 1) where each row includes two data validation drop down lists (source is on sheet2). I want the options in the second drop down list (k13) to be dependant on what is selected in the first drop down list (g13)...  ie. if you select 'Diary' in the first drop down box then the second drop down only has 'Cheese', 'Milk' and 'Yogurt' - likewise, if you select 'Fruit' in the first box - I want the only options to be available specific to that categories column in the lookup table on sheet 2 (which are 'apple', 'pear' and 'banana' in this case)?  Please help - i think this is a vlookup indirect formula?? Bending of light - photon's inertia instead of mass Intuitive meaning of Globally Hyperbolic I am been studying differential geometry and spacetime and I keep coming across the term .
