"getting second newest version of source code",
"I’m new to Mercurial. I’m trying to clone the second newest commit from the web interface, and everything I’ve red says I need to enter the revision number. However, the web interface only shows “age”, “author”, “description” and at the bottom has “rev 27: (0) tip”\nI know which one I want based on the description, and it’s the second from the top. How do I get it? I assume when I did hg clone https://... it got the newest version"

"PrimeNG data table sorting and pagination clicks is scrolling the page to top",
"I am currently using PrimeNG Datatable with pagination enabled in it. When I try to sort any column or click on pagination butttons, the page scrolls to top.\n\nIt is because primeng anchor tags have href=\"#\" by default, for example\n\n<a class=\"ui-paginator-page ui-paginator-element ui-state-default ui-corner-all\" href=\"#\" ng-reflect-klass=\"ui-paginator-page ui-paginator\" ng-reflect-ng-class=\"[object Object]\">2</a>\n\n\nIs there a way I can override the href values to something else like href=\"#/\" which would stop the scrolling to top?

"Conditional formatting with cell values based on their row",
"I'm currently doing a small side project where I'm converting images into excel spreadsheets. I have a python program which turns each cell into a range between 0 and 255 (RGB color codes).\nI had made this a while back and don't actually remember how I colored each row with conditional formatting.\nEssentially, I need to select each row, turn it a shade of red. Then I need to select each alternate row (MOD 2 = 0) and turn each of those into a shade of green. Finally, I need to select each third row (MOD 3 = 0) and turn those into a shade of blue.\nAgain, to reiterate, I'm having trouble with actually selecting the rows. Is there any way I can do this (without doing it by hand)?"

"How many threads do I really need?",
"I'm building a Java application with a GUI and a socket-based server, and I'm constantly running into problems with one part of the application getting stuck waiting for the other (mostly the GUI waiting for the server - no surprise there. The few times I manage to avoid these errors, I instead find myself reaching the end of my main method almost instantly after startup. (The app may or may not keep running, depending on if there is any GUI visible or not, but I though the main method wasn't supposed to return until the program is actually exiting...)\n\nMy requirements on the application are the following:\n\n\nIt should be able to handle an unspecified number of clients simultaneously\nCommunication between server and clients can go in either direction, and not necessarily every other turn; sometimes the server sends a bunch of messages and get replies from only some clients, other times it's the other way around.\nIt should never be \"too late\" for a client to connect - the serversocket needs to keep accepting connections continuously for as long as the server app is running.\nDuring the whole time, the GUI should be unaffected by the server and clients waiting for eachother. Updates to the GUI happens through event listeners on other objects (mostly the model) which are changed by the background threads.\n\n\nI've tried with the following, but I can't seem to get it right.\n\n\n1 thread for the main method and the \"regular\" work performed by objects it creates (Controller, Model etc). This is the thread I sometimes have problems with because it doesn't hold anywhere and returns from main prematurely.\nUsing EventQueue.invokeLater(new Runnable() { ... }); I perform all actual GUI manipulation on the UI thread, but none of these calls are \"surviving\" threads, so they basically just work asynchronically off the main thread.\n1 thread for the ServerSocket to be able to keep listening for new connections.\n1 thread for each client, to be able to listen to messages from clients. I'm unsure here if I need another thread here as well, to be able to send messages \"out of order\", i.e. without waiting to receive one first.\n\n\nI have never written a (real) multithreaded application before, so this is entirely new ground to me. However, I refuse to beleive that this problem has not been solved successfully before - even so many times that some sort of best practices have evolved.\n\nWhat are they? What is a good architecture for this application?"

"Converting synonymous records in CSV file into MySQL DB entries",
"I have an application which populates a text file with information in CSV format. The problem is, the number of columns for each records should be flexible and it's not constant. I am trying to implement the same datastructure but in MySQL for faster reading and parallel writing from many nodes. \n\nHere is a sample taken from my CSV File\n\nlike|love|adore|admire\nhate|dislike\nrevive|resurrect\ninfo|information|pieces of information|data\nshoot|snipe|kill|hunt\n\n\nEach record represents words with the same meaning. Later on, I get the synonyms of a word using that CSV file. For example, I get the synonyms for the word hate which is dislike using a function in my application that parses the csv file and outputs the matching words. \n\nWhat options do I have to do the same implementation approach but using MySQL?"

"Can not pass a list of strings to a Web API endpoint. Why?",
"Can not pass a list of strings to a Web API endpoint.

Once the breakpoint is hit the strs list inside the MyController.MyMethod is empty. The strs is not null, but it contains no elements. While my intentions and expectations are to see the strs containing one element, i.e. the string "bar".\nI am using the ASP.NET Core 2.2 in project where I create and use the HttpClient. And I am using the same ASP.NET Core 2.2 in project where I have the endpoint.\nI am not sure what is wrong here. I have checked a few sources.

"Angular Router Guard not called on back button press",
"I have an Angular app running inside an iframe that has a route guard for the module that I'm running. The route guard is activated whenever I navigate to the page using links inside the app or through the address bar, and routes the app to the correct component. But for some reason, when I click the back button from within the components, the module's route guard fails to fire and the app is navigated to the base component of the module - which should not be happening.\nI've tested and confirmed that router events do get fired when I press the back button inside one of the components using this :\nexport class FourthComponent {\n\n constructor(private readonly router: Router) {\n this.router.events.subscribe((event: NavigationStart) => {\n if (event.navigationTrigger === 'popstate') {\n console.log('back or forward button clicked');\n }\n });\n }\n\nThe console log does print whenever I click the back button from the secondary component screen.\nHere is the child module's routing module routes array:\nconst routes: Routes = [\n {\n path: '',\n canActivate: [SubModuleGuard],\n children: [\n {\n path: 'first',\n component: FirstComponent\n },\n {\n path: 'second',\n component: SecondComponent\n },\n {\n path: 'third',\n component: ThirdComponent\n },\n {\n path: 'fourth',\n component: FourthComponent\n },\n {\n path: '**',\n component: BaseComponent\n }\n ]\n }\n];\n\nFor some reason every time I click back button from the FourthComponent I'm navigated to the BaseComponent (Possibly the case for all child components of SubModule). If I then click the back button again it does a back operation for the parent of the iframe too.\nPlease tell me why the route guard (in this case SubModuleGuard) won't fire and how do I force the route guard to fire when the back button is clicked."

"Toggle NSStatusItem with NSMenu in Objective-C",
"I've got an application which toggle's a NSStatusItem from the preferences window. The preferences window has a checkbox \"enabled/disabled\" which calls the \"enabledStatusItem\" and \"disableStatusItem\"-methods in the class NSStatusItem.\n\nThis all works fine, my problem is adding a menu to this NSStatusItem. The code in the class NSStatusItem looks like this:\n\n-(void)enableStatusItem\n{\n //get icon\n theIcon = [NSImage imageNamed:@\"test.png\"];\n\n //create item\n statusItem = [[NSStatusBar systemStatusBar] statusItemWithLength:NSVariableStatusItemLength];\n [statusItem setImage:theIcon];\n [statusItem setHighlightMode:YES];\n [statusItem setMenu:statusMenu];\n}\n\n-(void)disableStatusItem\n{\n [[NSStatusBar systemStatusBar] removeStatusItem:statusItem];\n}\n\n\nEverything works, except setMenu. At first I loaded the StatusItem in awakeFromNib, then setMenu worked. But the StatusItem has to stay off when the preference checkbox is \"off\", so I couldn't load it in awakeFromNib anymore. \n\nI suspect setMenu doesn't load because it isn't in awakeFromNib, but \"enableStatusItem\" is called after awakeFromNib, so in awakeFromNib there isn't a statusItem yet to add the menu to. And I can't \"preload\" the statusItem because it is created with \"[[NSStatusBar systemStatusBar] statusItemWithLength:NSVariableStatusItemLength];\"\n\nI've tried a lot so far, even made a test-application where I added every piece of code one by one, so I could break it down. But without any success so far.\n\nI feel because it's such a simple thing, only one little NSMenu, isn't there a simple solution then?\n\nMaybe one of you guys has an idea?\n\nThanks in advance for your time,\nGreetings Frans"

"Google BigQuery clustered table not reducing query size when running query with WHERE clause on clustered field",

When I run the query on the non clustered table I get the following:\n\n\n\nWhen I run the query on the clustered table I get the following:\n\n\n\nHere is the schema of both the non clustered and the clustered table:\n\nDate TIMESTAMP NULLABLE\nUserId STRING NULLABLE\nEventCategory STRING NULLABLE\nEventAction STRING NULLABLE\nEventLabel STRING NULLABLE\nEventValue STRING NULLABLE\n\n\nThere is basically no difference between the two queries and how much data they look through and I can't seem to figure out why? I have confirmed that the clustered table is partitioned and clustered because in the BigQuery UI in table details it actually says so and running a query by filtering by Date greatly reduces the size of the data searched and shows the estimated query size to be much smaller. \n\nAny help here would be greatly appreciated!\n\nUPDATE:\n\nIf I change the query to:\n\nSELECT\n *\nFROM\n `table_name` \nWHERE\n EventCategory = \"ad\"\n\n\nI get the following result:\n\n \n\nThere are 53640 rows with EventCategory is \"ad\" and it looks like clustering did result in less table data being scanned, albeit not much less (529.2MB compared to 586MB).\n\nSo it looks like clustering is working but the data is not clustered properly in the table? How would I fix that? I have tried re-creating the table multiple times using DDL and even saving the table data to a JSON in GCS and then importing it into a new partitioned and clustered table but it hasn't changed anything.\n\nDoes the date partitioning sit on top of the clustering? Meaning that BigQuery first groups by date and then groups by cluster within those date groups? If so, I think that would probably explain it but it would render clustering not very useful."

"d3 zooming/panning behavior changes at millisecond intervals",
"I am working in a problem domain where I need to display data at millisecond time intervals. I have found that when you zoom in far enough on a graph, the behavior of the zoom/pan functions suddenly change! If you are using a time scale, this happens exactly when your axis starts displaying milliseconds.\n\nSpecifically, the behavior change is how d3 zooms around the mouse cursor. For intervals measured in seconds or above, the gridlines zoom with respect to the cursor position. i.e Mousing over 6PM and scrolling will cause 6PM to take up more space. But once you get to milliseconds, the grid seems to be zoomed from the far left, regardless of your cursor position. The panning also stops moving the axis around at all.\n\nI am not very experienced in d3, but to me, this looks like a bug. I see nothing in the zoom documentation about this. Is there a reason why it behaves this way, and if so, can it be overridden somehow?\n\nIn the links below, as soon as you zoom far enough that the x-axis labels change from :YY to .YYY (ie. :50 to .653) you should see the problem.\n\nThis shows the \"broken\" behavior: http://jsfiddle.net/JonathanPullano/LuYDY/3/\n\nThis shows the \"correct\" behavior: http://jsfiddle.net/JonathanPullano/LuYDY/2/\n\nEDIT: I have discovered that the problem is not in the zoom behavior, but rather the time.scale() itself. I made another fiddle which uses setTimeout to automatically rescale the axis without using zoom. The problem still persists. Try it here.\n\nhttp://jsfiddle.net/JonathanPullano/LuYDY/4/\n\nvar margin = {top: 20, right: 20, bottom: 30, left: 40},\n width = 600 - margin.left - margin.right,\n height = 400 - margin.top - margin.bottom;\n\nvar x = d3.time.scale()\n .domain([-5000, 5000])\n .range([0, width]);\n\nvar svg = d3.select(\"body\").append(\"svg\")\n .attr(\"width\", width + margin.left + margin.right)\n .attr(\"height\", height + margin.top + margin.bottom)\n .append(\"g\")\n .attr(\"transform\", \"translate(\" + margin.left + \",\" + margin.top + \")\");\n\nsvg.append(\"rect\")\n .attr(\"width\", width)\n .attr(\"height\", height);\n\nvar gXAxis = svg.append(\"g\")\n .attr(\"class\", \"x axis\")\n .attr(\"transform\", \"translate(0,\" + height + \")\")\n\nfunction chart(selection) {\n selection.each(function(data) {\n\n var xAxis = d3.svg.axis()\n .scale(x)\n .orient(\"bottom\")\n .ticks(5)\n .tickSize(-height);\n\n gXAxis.call(xAxis);\n });\n}\n\nupdate();\nfunction update() {\n var start = new Date(x.domain()[0].getTime() + 10);\n var end = new Date(x.domain()[1].getTime() - 10);\n if(start.getTime() < end.getTime()) {\n x.domain([start,end]);\n setTimeout(update,10);\n }\n svg.call(chart);\n}"
