How do I get jQuery to select elements with a . (period) in their ID? Given the following classes and controller action method:  public School {   public Int32 ID { get; set; }   publig String Name { get; set; }   public Address Address { get; set; } }  public class Address {   public string Street1 { get; set; }   public string City { get; set; }   public String ZipCode { get; set; }   public String State { get; set; }   public String Country { get; set; } }  [Authorize(Roles = "SchoolEditor")] [AcceptVerbs(HttpVerbs.Post)] public SchoolResponse Edit(Int32 id, FormCollection form) {   School school = GetSchoolFromRepository(id);    UpdateModel(school, form);    return new SchoolResponse() { School = school }; }   And the following form:  &lt;form method="post"&gt;   School: &lt;%= Html.TextBox("Name") %&gt;&lt;br /&gt;   Street: &lt;%= Html.TextBox("Address.Street") %&gt;&lt;br /&gt;   City:  &lt;%= Html.TextBox("Address.City") %&gt;&lt;br /&gt;   Zip Code: &lt;%= Html.TextBox("Address.ZipCode") %&gt;&lt;br /&gt;   Sate: &lt;select id="Address.State"&gt;&lt;/select&gt;&lt;br /&gt;   Country: &lt;select id="Address.Country"&gt;&lt;/select&gt;&lt;br /&gt; &lt;/form&gt;   I am able to update both the School instance and the Address member of the school.  This is quite nice!  Thank you ASP.NET MVC team!  However, how do I use jQuery to select the drop down list so that I can pre-fill it?  I realize that I could do this server side but there will be other dynamic elements on the page that affect the list.  The following is what I have so far, and it does not work as the selectors don't seem to match the IDs:  $(function() {   $.getJSON("/Location/GetCountryList", null, function(data) {     $("#Address.Country").fillSelect(data);   });   $("#Address.Country").change(function() {     $.getJSON("/Location/GetRegionsForCountry", { country: $(this).val() }, function(data) {       $("#Address.State").fillSelect(data);     });   }); }); I wanted to remove and reinstall the software-center package.  I removed it, but now I can't reinstall.  I tried these commands without success:  sudo apt-get update sudo apt-get install software-center   How can I reinstall software-center?    When I performed the install command this is what I got:  $ sudo apt-get install software-center Reading package lists... Done Building dependency tree        Reading state information... Done Package software-center is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source  E: Package 'software-center' has no installation candidate Why do wet objects become darker? Bottom to top explanation of the Mahalanobis distance? I'm studying pattern recognition and statistics and almost every book I open on the subject I bump into the concept of Mahalanobis distance. The books give sort of intuitive explanations, but still not good enough ones for me to actually really understand what is going on. If someone would ask me "What is the Mahalanobis distance?" I could only answer: "It's this nice thing, which measures distance of some kind" :)   The definitions usually also contain eigenvectors and eigenvalues, which I have a little trouble connecting to the Mahalanobis distance. I understand the definition of eigenvectors and eigenvalues, but how are they related to the Mahalanobis distance? Does it have something to do with changing the base in Linear Algebra etc.?  I have also read these former questions on the subject:       I have also read .  The answers are good and pictures nice, but still I don't really get it...I have an idea but it's still in the dark. Can someone give a "How would you explain it to your grandma"-explanation so that I could finally wrap this up and never again wonder what the heck is a Mahalanobis distance? :) Where does it come from, what, why?   UPDATE:   Here is something which helps understanding the Mahalanobis formula: When I ssh into my Ubuntu 18.04 box I get the motd  1 update could not be installed automatically   Which goes on to tell me to check the unattended-upgrades log.  The log shows no problems. How can I clear this bogus message? 'longtable' caption without incrementing 'table'? For reasons both complex and confusing, I would like to caption a longtable without incrementing the table counter in the process.  I want to have two consecutive longtable environments to be captioned with identical table numbers; i.e. one longtable captioned "Table x.y: Data Set (Part A)" and one captioned "Table x.y: Data Set (Part B)", with x.y being identical for both tables.  Apparently however, even \caption*{} command bumps table. I am a bit at a loss here.  Note: I know that the xtab package would enable me to have one long table with switches of headers and captions mid-table. However I got a (different) problem with that package, akin to  but sadly not solved by egreg's answer there; so this question should be considered longtable-only as xtab, supertabular etc. don't float my boat right now. :-( Other users have been leaving me angry and hostile comments accusing me of plagiarism and saying that I'm a liar and I should stop stealing answers. But I have only been copying content from other sites, not taking answers from other users.   I don't understand what is wrong here. Shouldn't we be focused on building all the content and knowledge in a single place, much like Wikipedia does?  What does it matter that I copy and paste content I've found elsewhere so long as the question gets an answer?

However, due to the use of my \aboverulesep and \belowrulesep, I now have gaps above and below my table row that is not coloured.   Also, because of the use of my @{} on either side of the table to 'remove' the excess padding on the sides of the table, the row colour is being applied in those padding as well.   Qn 1: How can I colour the aforementioned gaps (arising due to the \aboverulesep) in, while maintaining the rule separation?   Qn 2: How to remove the colour from the two sides of the table?     EDIT  This is in response to Zarko's answer. I want to maintain the use of @{} on either side to remove the padding.

As it is, SE kind of stands out (in a not cool way): How can I suppress the year from appearing in the bibliography for entries of type @inproceedings?  In my specific case the year is implied in the booktitle (e.g. FOCS '09) so it is redundant when I need to save space.  I found  and the "second solution" looks promising but I am not sure how to translate it to only suppress the year for one type of entry. I am guessing \ifentrytype might be helpful.

(as of 2020) Astrophysicists believe that dark energy exists and makes up ~70% of the universe's energy content. What is the evidence that dark energy exists? Wikipedia gives :   Supernovae. A specific type of supernovae (type 1A) are supposed to be standard candles - that is, their luminosity is known. In turn this lets us measure distance to faraway galaxies, check how fast those galaxies are receding from us, and check if that recession speed is increasing over time. CMB. Data from the Cosmic Microwave Background indicates the universe is approximately flat. Visible matter + dark matter can account for ~30% of the energy content required to make the universe flat, leaving ~70% for something else - dark energy. BAO. Baryon acoustic oscillations act as a "standard ruler" that lets us measure how the Hubble constant varies with redshift (i.e. time), and see if the recession speed is increasing with time. Late-time ISW. ISW stands for integrated Sachs-Wolfe effect. The idea is that, usually, a photon that enters a potential well gains energy as it falls in and loses energy as it emerges, and gain/loss exactly cancel. If a universe is expanding in accelerated fashion, then this is untrue; the potential wells / hills are smoothed out and there is a permanent shift in the photon's energy and therefore temperature. If we see a correlation between hot and cold spots on the CMB and the locations of superclusters and voids, then it's a sign of accelerated expansion. Galaxy evolution. This uses (known) evolution of early-type galaxies as a standard clock. Once we know how long it takes for a galaxy to evolve from one state to another, as well as their redshifts, we can reconstruct how the Hubble constant varies over time, and see if the recession speed is increasing with time.   Two questions:   Did I understand any of these five methods wrong? Are there any other lines of evidence for the existence of dark energy? Are there strange attractors whose coordinates are "almost integers"? Which commit has this blob? Given the hash of a blob, is there a way to get a list of commits that have this blob in their tree? How to align the camera in a solved motion tracked scene? I have been having an issue with my floor plane and object when using a solved camera after tracking some footage. I get a solve error of between 0.05 and 0.4 on my solves which is good and not the issue I've been having. However when I go to orient the camera I will snap it to an origin and adjust the scale. The plane and object are not aligned, but could be fixed if I could just rotate around them (much like in PF Track). I would think the pivot point for the camera, if I have it locked to view, would be the origin (where my plane and object are), but it seems to be just some arbitrary point out in space which makes manually fixing the alignment very difficult. I'm wondering if there is any way to fix this so the pivot point is in fact in the center, or if there are any other suggestions to go about this problem. "R cannot be resolved to a variable"? Are there any significant plot elements in Fantastic Beasts that will be missed if I haven't seen the Harry Potter films? I have read all seven Harry Potter books, and The Cursed Child1, but I've only watched the first two movies.  Do I have to watch all eight movies in order to fully understand the significant plot points found in Fantastic Beasts and Where to Find Them?  Is there anything that I'll miss by not having seen them?    1 Waste of money, that. How can we move an object with zero velocity? Consider there is a box of mass $m$ at rest on the floor. Most books give an example that we need to do a work of $mgh$ to lift the box $h$ upward.  If we analyze this work done, the external force acting on the box by us should be equal to the weight of the box. Therefore the net force is zero which in turn there is no acceleration. If there is no acceleration and the initial velocity of the box is also zero, how can the box move upward? Proof that Epicycloids are Algebraic Curves? Epicycloids are most commonly described by the parametric equations,   $x(t) = (R + a)\cos(t) – a \cos \left(\frac{R + a}{a} t \right),$  $y(t) = (R + a)\sin(t) – a \sin \left(\frac{R + a}{a} t \right).$  Where $R$ is the radius of the fixed circle and $a$ is the radius of the rolling circle.   With $R = ka$ we also have,   $x(t) = a[(k + 1)\cos(t) - \cos((k + 1)t)],$  $y(t) = a[(k + 1)\sin(t) - \sin((k + 1)t)].$  Several books discussing epicycloids mention that if the ratio of the radii of the circles $\left( \frac{R}{a} = k \right)$ is rational, then they are algebraic curves. However, I’ve only been able to find the Cartesian equations for the cardioid, nephroid and ranunculoid. With the cardioid being,   $(ax + x^2 + y^2)^2 = a^2(x^2 + y^2).$   The nephroid,   $(-4a^2 + x^2 + y^2)^3 = 108a^4y^2.$  And the ranunculoid,   $-52521875a^{12} – 1286250a^{10} (x^2 + y^2) – 32025a^8 (x^2 + y^2)^2 + 93312a^7 (x^5 – 10x^3y^2 + 5xy^4) – 812a^6 (x^2 + y^2)^3 – 21a^4 (x^2 + y^2)^4 – 42a^2(x^2 + y^2)^5 + (x^2 + y^2)^6 = 0.$  Clearly this doesn’t cover all epicycloids where $\frac{R}{a}$ is rational.   What is the proof that shows that epicycloids, where the ratio of the radii are rational, are algebraic curves?
