问题 When writing event based cloud functions for firebase firestore it's common to update fields in the affected document, for example: When a document of users collection is updated a function will trigger, let's say we want to determine the user info state and we have a completeInfo: boolean property, the function will have to perform another update so that the trigger will fire again, if we don't use a flag like needsUpdate: boolean to determine if excecuting the function we will have an

问题 Is there any difference between the two following statements. They achieve the same end, correct? Do they compile to the same Java code? Is there any performance difference between them or is it just a matter of preference/readability? for (thing <- things) { doSome(thing) } things.foreach( thing => doSome(thing) ) 回答1: for comprehensions are defined as simple syntactic translations. That's extremely important, because that allows any object to work with for comprehensions, it just has to

问题 I've got two lists of lists, I match them and print any differences. The two lists are cable connections within a FPGA station. I need to ensure: All the connections on the $list1 exist on $list2 , if not, it should save the error on another list All the connections on $list2 exist on $list1 , so I don't get any 'wrong' connections. Any connections that don't exist on either list should be saved onto another variable. The lists are in this format: {{A.B2} {B.B3}} and the the $list2 equivalent

问题 I am working with Nginx on Docker and I want to assign each user to a different port. First, without adding anything, my code works fine: location /viewer/ { proxy_pass http://xx.xxx.xxx.xxx:18080/Road/; } Going to "/viewer/" in URL will proxy to the port 18080, just as expected. But if I add any variable to the proxy_pass like: set $test 1; proxy_pass http://xx.xxx.xxx.xxx:18080/Road/?$test; then, first of all, the static files do not load anymore and I have to add lines like these: location

问题 So I am have this issue with Google Apps Script. It is timing out because the app server requests are taking too long. I was just wanting to see if my coding could be cleaned up a bit to run faster or is there another method which would work? Code below: for (var y = 1; y < listLast ; y++) { var matchor = listSheet.getRange("B" + y).getValue(); var listEmCo = listSheet.getRange("A" + y).getValue(); if(matchor == "Match") { Logger.log("Do Nothing"); } else { for (var x = 0; x < formLast; x++)
