How to copy the "Local Items" Keychain to a new mac?
How do I migrate my Keychain's "Local Items" to a new Mac?
How do you do a deep copy of an object in .NET? I want a true deep copy. In Java, this was easy, but how do you do it in C#? Earlier I asked a question about  and got the answer that while it is only necessary for anonymous types, that it is used nonetheless to make writing code 'quicker'/easier and 'just because'.  Following  I saw that var gets compiled down to the correct type in the IL (you will see it about midway down article).  My question is how much more, if any, IL code does using the var keyword take, and would it be even close to having a measurable level on the performance of the code if it was used everywhere? Why are news headlines in present tense if they refer to past events? In news papers we see headings like this  &quot;India signs a pact with Russia&quot; &quot;Sachin hits another century&quot; &quot;Obama wins presidential election&quot;  These are completed events, aren't they? Then, why are these sentences not mentioned in past tense? What is a "year" in Westeros? How to remove enamel from wire? I want to repair my computer mouse cable which has become disconnected from the PCB. The wire is insulated with enamel and I have to remove it before soldering it back onto the board.  How should I remove the enamel? How do I time a method's execution in Java? Matrix Group induction proof and order of elements question I would like the user to have full rights on this folder (as well as all sub-directories and files in it):  ~/.blabla   currently owned by root.  I have found numerous posts (in this forum and elsewhere) on how to do this for files but I can't find a way to do it for whole folders. I'm looking for a book I read in Junior High (probably) about a world where everyone was basically the same race.  One genetically pure male and female teenager of each race still exists.  They are transporting a genetically pure boy to meet his genetically pure female counterpart and accidentally introduce him to a genetically pure female of a different race.  And, of course, chaos ensues.  Any thoughts? Let $\{X_n\}_{n=1}^\infty$ be a sequence of random variables converging to a random variable $X$. Does this fact implies that $\lim\limits_{n\to \infty} EX_n = EX$?  If not, is there any other sufficient condition? How to delay a program such as cairo-dock (No openGL) or Firefox?  Sometimes programs crash when started with other startup apps. I want programs to start 10 seconds late to avoid a crash. Checking integrity of my server data How can I find out which apps I have already downloaded on my iPhone? When you attempt to download an app that costs money, you will not be charged if you already bought the app. After you press buy and enter your iTunes password, it will say "You have already purchased this item. To download it again for free, select OK."  The problem is that I deleted hundreds of apps from my phone, some of which were paid for. Later on I might find an app I like but notice that it costs money. It might be an app I had already paid for, or an app which I got when it was free.  How can I know if I tap the buy button if I will be charged for the app or not?  In other words, how can I know if I owned a previous version of an app before? Probability of continuous random variable This is not for homework. (I am a grader for a class.)  The case in which $G$ is finite is trivial. (That is, use a corollary to Lagrange's Theorem, and set $[G:H] = \dfrac{|G|}{|H|}$, and similarly for $[H:K]$.) How do you prove this for when $G$ is infinite?   The proof of this statement that I know well tries to show that $[G:K]$ is finite iff $[G:H]$ and $[H:K]$ are finite, but I am not a fan of that proof. For pedagogical purposes, I'm looking for a better proof. (The course uses right cosets by convention.)  The course has just started covering normal subgroups, so things like the Isomorphism Theorems are not known yet. Are units in English singular or plural? I am a little bit confused about using units in English, sometimes I hear that people use singular units for plural things, sometimes they use plural ones. Which one is correct?   3 meter(s) long? during a 2 week(s) period? 0.5 dollar(s) How would I go about creating a 3D MMORPG Mouse Look? How would I go about creating a 3D MMORPG Mouse Look? I have created a 3D Space Rpg that is almost finished with success so far. However, I didn't have a clue, how I would attempt to make a Mouse Look method where if a user right clickes and then holds the right mouse button and moves it around the camera moves around with the mouse. The camera can not move away from your character/ship, it should act as if the character/ship is it's origin and that it rotates all around the origin.  I don't mind coding this with python either. Advice is welcome! How do I prevent mouse movement from waking up a suspended computer? Why isn't an infinite, flat, nonexpanding universe filled with a uniform matter distribution a solution to Einstein's equation? Custom DataTable using Vanilla Datables in LWC I'm trying to build a custom datable because I want the functionality to sort, search and paginate and also add action buttons in each row. Initially, my VF page was using  but we have now decided to rebuild that page in LWC.  I found a similar  but it hasn't really worked for me.  I then found  (Javascript) and  (ES2018) I have tried to implement Vanilla Datatables but I keep running into issues such as:      TypeError: Cannot read property 'length' of undefined   The above error is thrown because the library is unable to find the body of the table.   My point is that I feel this library won't work because it's using document, window and so on.   I was wondering if there is a way I could convert this library to something that is more suited to LWC basically have it "export" the modules. Since I'm not a JS expert I'm unable to put the pieces together.   Just for some context, I'll post my code here:  &lt;template&gt;     &lt;table class="sobject-table slds-table slds-table_cell-buffer slds-table_bordered"&gt;         &lt;thead&gt;             &lt;tr class="slds-line-height_reset"&gt;                 &lt;template for:each={fieldSetData} for:item="field"&gt;                     &lt;th key={field.apiName} title={field.fieldLabel} class="" data-scope="col"&gt;                         &lt;div class="slds-truncate" title={field.fieldLabel}&gt;{field.fieldLabel}&lt;/div&gt;                     &lt;/th&gt;                 &lt;/template&gt;             &lt;/tr&gt;         &lt;/thead&gt;         &lt;tbody&gt;             &lt;template for:each={records} for:item="row"&gt;                 &lt;tr key={row} class="slds-hint-parent"&gt;                     &lt;template for:each={row} for:item="data"&gt;                         &lt;td key={data.id} data-label="Name" data-scope="row"&gt;{data.value}&lt;/td&gt;                     &lt;/template&gt;                 &lt;/tr&gt;             &lt;/template&gt;         &lt;/tbody&gt;     &lt;/table&gt; &lt;/template&gt;   import {LightningElement, api, wire} from 'lwc'; import {processRecords} from 'c/recordGenerator'; import getFieldSetData from '@salesforce/apex/FieldSetData.getFieldSetData'; import getSobjectRecords from '@salesforce/apex/DeomoCTRL.getRecords'; import VanillaDatatable from '@salesforce/resourceUrl/VanillaDatatable'; import {loadScript, loadStyle} from 'lightning/platformResourceLoader';  export default class ManageSelectedIndicators extends LightningElement {     @api recordId;     records;     fieldSetData;     @wire(         getFieldSetData,         {objectName: 'SOBJECTName', fieldSet: 'FIELSETName'}     ) wiredFieldSetData({error, data}) {         console.log('wired called in Child')         if (data) {             this.fieldSetData = data;             this.getData();         }     }       constructor() {         super();         console.log('Constructor called in Child');     }      connectedCallback() {         console.log('Connected callback');     }      renderedCallback() {         console.log('Rendered callback');         Promise.all([              loadScript(this, VanillaDatatable + '/VanillaDataTables/src/vanilla-dataTables.js')          ]).then(() =&gt; {              const table = new DataTable(                  document.getElementsByClassName('.sobject-table'),                  //Also tried this.template.querySelector('.sobject-table'),                  {searchable: true, sortable : true}              );          })          .catch(error =&gt; {             console.log(error);          });     }      getData() {         getSobjectRecords ({             sobjectId: this.recordId         })         .then(response =&gt; {             this.records= processRecords(response, this.fieldSetData);         })         .catch((error) =&gt; {             console.log(error);         });     }  }   Edit: I have also tried lwc:dom="manual" that didn't seem to work either.  Is there any other way I could achieve these functionalities? Or do I have to write custom code to achieve this?
