LWC: Difference between "window" and "this" I am trying to understand what exactly is the difference between window and this in the context of a LWC component.  According to this  the Locker intercepts calls to the Window and uses Secured Window instead which acts as:     Secure wrapper for the window object, which represents a window containing a DOM document.   As for this what I  was:     To add an event listener to an element that a template doesn’t own,   call addEventListener directly: this.addEventListener()   What does salesforce mean by an element that a template doesn't own? Isn't window an element that the template doesn't own? Machine Learning - Where is the difference between one-class, binary-class and multinominal-class classification? Where is the difference between one-class, binary-class and multinominal-class classification?  If I like to classify text in lets say four classes and also want the system to be able to tell me that none of these classes matches the unknown/untrained test-data.   Couldn't I just use all the methods that I mentioned above to reach my goal? e.g. I could describe C1, C2, C3 and C4 as four different trainings-sets for binary-classification and use the trained models to label an unknow data-set ...  Just by saying, Training-Set for C1 contains class 1 (all good samples for C1) and class 0 (mix of all C2, C3 and C4 as bad samples for C1).  Is unlabeled-data C1 -> 1 or 0  Is unlabeled-data C2 -> 1 or 0 ... and so on ...  For multinominal classification I could just define a training-set containing all good sample data for C1, C2, C3 and C4 in one training-set and then use the one resulting model for classification ...  But where is the difference between this two methods? (except of that I have to use different algorithms)  And how would I define a training-set for the described problem of categorizing data in those four classes using one-class classfication (is that even possible)?  Excuse me if I'm completely wrong in my thinking. Would appreciate an answer that makes the methodology a little bit clearer to me =) SQL Server Query Plan Hash Collision I'm wondering if anyone can shed light on a worry of mine that a query_plan_hash collision could cause a query to be executed as an entirely different query.  The hash is a 16 digit Hex that sp_help sys.dm_exec_query_stats says is a binary. Therefore it's only a 64 bit hash, and a collision seems very probable (considering SHA1 [160 bit] was just verified to have had collisions).  Would the plan_hash and the query_plan_hash both have to collide for this (query to be executed as an entirely different query) to happen?  I'm also curious if there is a setting somewhere in SQL Server that will allow us to change this hash to SHA2-512 (to reduce the possibility of a collision). Our data is very important.  I searched high and low via Google and Stack Exchange forums. What is the magnetic field inside hollow ball of magnets? Setup: we have a large number of thin magnets shaped such that we can place them side by side and eventually form a hollow ball. The ball we construct will have the north poles of all of the magnets pointing toward the center of the ball, and the south poles pointing away from the center. The magnets in this case are physically formed such that in this hollow ball arrangement they are space filling and there are no gaps between them.  Is such as construction possible? If so, what is the magnetic field (B-field) inside and outside the ball? Before marking this post duplicate or voting to get it closed (the reason for which I simply don't get just because it is a grammar forum after all! If I am seeking recommendation for a book that means I will be coming back someday to the same site for my doubts also provided I get a not so harsh reply!), please read this and help this MBA aspirant.   A little about myself and my research so far. I am a very critical reader of English Grammar and the kind of person who aims at perfection.  Currently, I am keen on taking on English grammar again after a certain gap. Well, I am aiming for MBA, so preparing for entrance exams for the same.  I bought the religiously followed Wren and Martin and started studying it chapter by chapter. I was surprised when I read the pronouns chapter. I studied all the rules given and then started practising but it came as surprise when I found when many of the attempted questions were wrong. The reason simply being the rules for those specific sentences were not given.   For example:     We scored as many goals as they/them?    According to me, the answer should be they, but it's them according to the solution manual. Worse still, the solution manual offers no explanation for this.  So after a chat with my teachers I was suggested to follow the blogs of grammarians and look for any rules for the sentences that have contradictory answers!  I did so and was clarified by  post of pronouns, Rule 5.  Then I saw a book by the same author. I was momentarily happy. It was Momentarily because the reviews on Amazon were too bad about this book. After reading a couple of forums about the book I found a common statement saying that no grammar book is exhaustive.  So, it's okay for me to have more than one. And my simple question is what will be a good and almost exhaustive (if not fully exhaustive) book of English grammar to help get through the subtle usages of English in my management entrances  which is crisp and to the point and yet covers all important rules and syntax, and most importantly having practice tests at the end with solutions and explanations? How to search for list of papers citing both papers A and B? For given papers A and B, I would like to search for all papers that cite both A and B. I guess one can generalize to papers {A,B,C,...} and find all papers that cite all of them.   A quick Google Scholar and Web of Science search revealed nothing. Google Scholar has a "cite=..." thing in the URL, which I messed with a bit to no avail. I'm taking my first crack at  with jQuery. I'm getting my data onto my page, but I'm having some trouble with the JSON data that is returned for Date data types. Basically, I'm getting a string back that looks like this:  /Date(1224043200000)/   From someone totally new to JSON - How do I format this to a short date format? Should this be handled somewhere in the jQuery code? I've tried the jQuery.UI.datepicker plugin using $.datepicker.formatDate() without any success.  FYI: Here's the solution I came up with using a combination of the answers here:  function getMismatch(id) {   $.getJSON("Main.aspx?Callback=GetMismatch",     { MismatchId: id },      function (result) {       $("#AuthMerchId").text(result.AuthorizationMerchantId);       $("#SttlMerchId").text(result.SettlementMerchantId);       $("#CreateDate").text(formatJSONDate(Date(result.AppendDts)));       $("#ExpireDate").text(formatJSONDate(Date(result.ExpiresDts)));       $("#LastUpdate").text(formatJSONDate(Date(result.LastUpdateDts)));       $("#LastUpdatedBy").text(result.LastUpdateNt);       $("#ProcessIn").text(result.ProcessIn);     }   );    return false; }  function formatJSONDate(jsonDate) {   var newDate = dateFormat(jsonDate, "mm/dd/yyyy");   return newDate; }   This solution got my object from the callback method and displayed the dates on the page properly using the date format library.

Hydrogen and antihydrogen atoms produce the same spectroscopy when excited, and adsorb the same frequencies. The charge does not make a difference in the potential (regardless if it's generated by a proton or an antiproton) nor in how the positron behaves in this potential (being its mass equal to the mass of an electron)  How can astronomy evaluate if a far galaxy is made of matter or antimatter, given that from the spectroscopy point of view, they behave in the same way? In other words, how do we know that an asymmetry exists between matter and antimatter in the universe? Cannot replace a packed image in the uv image editor I was trying to replace an image in my UV image editor, but the image defaults to a different image. how do I fix this? Bounty not awarded automatically — bug? RF Energy Harvesting Why can energy invested in RF radiation not be harvested fully? What are the main factors that affect this? Is there any significant research nowadays that fully describes this process? I stand on the conclusion: "Energy moves from one form to another.", but in this case why can it not be harvested in that quantity to use it for powering low-power devices or store it in significant quantities in some batteries for later use? Why is it not profitable nowadays and why is it not used today like energy from water, wind and other energy sources? Please bring back the oldest sort order for answers, I think we can deal with four different types of sort order.  It's helpful if you don't want to have to tool-tip every post to see which got posted first, so that you can upvote the oldest answer when answers duplicate each other.  Edit:  Also, trying to read newest backwards doesn't work well for questions with multiple pages of answers. Property of Entire Functions I get this error in the deployment step of a share-point farm based project. Most of the suggested solutions on the net are a simple Visual Studio re-start, however, a simple VS restart won't fix this.   Any ideas on what might be causing this? What does `exec {STDIN}>&0` do?
