"Does ArcView and/or R use Graphics Card (GPU) acceleration",

But when I posed the question to knowledgeable computer users that don't use GIS or R they asked about the GPU and if either program uses GPU acceleration.

"Low disk space causes RabbitMQ to loose messages instead of blocking the connection",
"I have a java application that publishes messages to a RabbitMQ server.\nWhen the available disk space drops below rabbit's low watermark I get unexpected behavior. \n\nThe expected behavior is that the connection will become blocking, making my application hang on the call to Channel.basicPublish.\n\nThe actual behavior is that the connection appears to be blocking in the management console, but calls to Channel.basicPublish return with no errors and the messages that were supposed to be published are lost.\nThis behavior undermines the most important feature of RabbitMQ, which is robustness.\n\nBelow is a minimal version of my application for testing. All it does is publish a message every second with an incrementing index (1, 2, 3, ...). The messages are received just fine by the RabbitMQ server, until I set the low watermark to a very high value, by putting the following line in the rabbitmq.config file:\n\n[ \n {rabbit, [{disk_free_limit, 60000000000}]}\n].\n\n\nAfter restarting the server, I get a low disk space notification in the management console, the connection is marked as 'blocking', and no more messages are received by the server. However, the application keeps running and sending messages as if nothing is wrong.

"Win32: Set text length in Tree View with cchTextMax",

After dropping the element, I apply the drag event on the right container. However, the Hammer.js drag event is activated and it considers the deltaX and deltaY from the previous dragstart event.\n\nHammer.js is being used with preventDefault: true:\n\nHammer(this.container, {preventDefault: true}).on('dragstart', function (event) { ... }\n\n\nI have already used event.preventDefault() and event.stopPropagation() on the dragstart of the draggable element, without success.\n\nI have also partially solved the problem. In the dragstart event of the Hammer.js container, I have added the following verification, in order to check if the source element and the target are the same. However, the drag in the right container only works on the second action, since the first one is ignored.\n\nif (event.gesture.startEvent.srcEvent.srcElement != event.gesture.target) {\n return false;\n}\n\n\nAny idea on how to prevent Hammer.js events while dragging elements using the HTML5 drag and drop API?\n\nI want to use flags as a last resort, since Hammer.js events should be developed by third-parties.\n\nThanks for your help."

"Most computationally efficient algorithm to create square sub-matrices of 1's along the diagonal of a large matrix, given size specs of sub-matrices",
"Given a list of numbers, for example [2, 4, 1, 3], create a square matrix of dimension sum(list) x sum(list) , where along the diagonals , there are square matrices of the sizes specified by the list. In the case of [2, 4, 1, 3] , that would result in\n\n1 1 0 0 0 0 0 0 0 0\n1 1 0 0 0 0 0 0 0 0\n0 0 1 1 1 1 0 0 0 0\n0 0 1 1 1 1 0 0 0 0\n0 0 1 1 1 1 0 0 0 0\n0 0 1 1 1 1 0 0 0 0\n0 0 0 0 0 0 1 0 0 0\n0 0 0 0 0 0 0 1 1 1\n0 0 0 0 0 0 0 1 1 1\n0 0 0 0 0 0 0 1 1 1\n\n\nThe method should generalize to any (positive) values in the list, and any length of list. \n\nWhat I came up so far:\n\nBrute force method: Create each sub matrix individually, and then concatenate all of them them. This becomes very inefficient of several of the size specifications are of size 1."

Does such an implementation already exist or do I have to reinvent the wheel and create a UserManager?\nUpdate:\nAfter a lot of cussing and searching I was able to create the UserManager instance with the following code:\npublic UserManager<AspNetUser> UserManager\n{\n get\n {\n var store = new UserStore<AspNetUser, AspNetRole, AuthorizationDbContext, Guid, AspNetUserClaim, AspNetUserRole, AspNetUserLogin, AspNetUserToken, AspNetRoleClaim>(Context);\n \n var manager = new UserManager<AspNetUser>(\n store, \n null, \n new PasswordHasher<AspNetUser>(), \n new []{new UserValidator<AspNetUser>()},\n new IPasswordValidator<AspNetUser>[]{},\n new UpperInvariantLookupNormalizer(),\n new IdentityErrorDescriber(), \n null,\n NullLogger<UserManager<AspNetUser>>.Instance);\n\n return manager;\n }\n}\n\nThat allows me to update the datastore with the claim, but it's not being returned when I log in.\nUsing .Net Core 3.1, v3.10 of the Microsoft NuGet packages.\nMy Startup.cs has the following added:\n.AddOpenIdConnect("oidc", options =>\n{\n options.Authority = Configuration.GetSection("Authentication")["Authority"];\n options.ClientId = Configuration.GetSection("Authentication")["ClientId"];\n options.ClientSecret = Configuration.GetSection("Authentication")["Secret"];\n options.ResponseType = "code";\n options.SaveTokens = true;\n options.GetClaimsFromUserInfoEndpoint = true;\n options.ClaimActions.MapAll();\n options.Events.OnUserInformationReceived = async context =>\n {\n var mi = services.BuildServiceProvider().GetRequiredService<IModuleInfo>();\n mi.ClearLoggedInUsersCache();\n\n var userManager = services.BuildServiceProvider().GetRequiredService<UserManager<AspNetUser>>();\n var userName = context.User.RootElement.GetString("name");\n\n // Get the user object from the database.\n var currentUser = (\n from u in userManager.Users\n where u.NormalizedUserName == userName\n select u\n ).FirstOrDefault();\n\n // Get the claims defined in the database.\n var userClaims = await userManager.GetClaimsAsync(currentUser);\n\n // -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-=-\n // Just need to figure out how to attach them to the user.\n // -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-=-\n };\n\nSo now I can pull the claims using UserManager, but have no way to persist them to the user information to maintain across requests. Still missing a piece to the puzzle. But still seems odd that IdentityServer4 isn't returning the associated claims."

"Ember.js how does reopenClass work?",
"I don't really get the function of ember.js' reopenClass. I thought it added extra code to the Object's prototype, so all instances of that Object would get the functionality that was added in a non static way. It does not do this however. It looks like it only adds code that can be statically executed. For instance. I have this code:\n\nLogger = Ember.Object.extend({ \n log: function(thing) { \n console.log(thing + ' wassup'); \n }\n});\n\nvar logger = Logger.create();\nlogger.log(\"1, yo\")\n\nlogger.reopen({ \n log: function(name) { \n console.log(name + 'ghurt')\n }\n});\nlogger.log(\"2, yo\")\n\nLogger.reopenClass({ \n log: function(name) { \n console.log(name + 'fresh')\n }\n});\nlogger.log(\"3, yo\")\nLogger.log(\"4, yo\")\n\n\nIt outputs this:\n\n1, yo wassup\n2, yoghurt\n3, yoghurt\n4, yofresh\n\n\nWhat I expected was this:\n\n1, yo wassup\n2, yoghurt\n3, yofresh\n4, undefined (I think)\n\n\nSo my question is: What does reopenClass do and when do I use it?"

Towards the end of the section, the following CWG issue is mentioned\n\nhttp://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#2054\n\nHere again it is stated that the standard does not explicitly allows the example reproduced in the issue.\n\nI am a bit baffled because it seems to me that, e.g., the usage of enable_if in partial specializations has been standard practice for quite some time (see for instance the Boost documentation, which explicitly mentions partial specializations).\n\nAm I misunderstanding the points in the documents above or is this really a grey area?"

"I still need your help.\nI have this piece of code that doesn't want to work.\n\n-(void)tableView:(UITableView *)_tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {\n\nif (editingStyle == UITableViewCellEditingStyleDelete) {\n\n NSDictionary *rowVals = (NSDictionary *) [shoppingListItems objectAtIndex:indexPath.row];\n NSString *keyValue = (NSString *) [rowVals objectForKey:@\"key\"];\n\n [tableView beginUpdates];\n\n sqlite3 *db;\n int dbrc; //Codice di ritorno del database (database return code)\n DatabaseShoppingListAppDelegate *appDelegate = (DatabaseShoppingListAppDelegate*) [UIApplication sharedApplication].delegate;\n const char *dbFilePathUTF8 = [appDelegate.dbFilePath UTF8String];\n dbrc = sqlite3_open(dbFilePathUTF8, &db);\n if (dbrc) {\n NSLog(@\"Impossibile aprire il Database!\");\n return;\n }\n\n sqlite3_stmt *dbps; //Istruzione di preparazione del database\n\n NSString *deleteStatementsNS = [NSString stringWithFormat: @\"DELETE FROM \\\"shoppinglist\\\" WHERE key='%@'\", keyValue];\n const char *deleteStatement = [deleteStatementsNS UTF8String];\n dbrc = sqlite3_prepare_v2(db, deleteStatement, -1, &dbps, NULL);\n dbrc = sqlite3_step(dbps);\n\n\n //faccio pulizia rilasciando i database\n sqlite3_finalize(dbps);\n sqlite3_close(db);\n\n [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];\n [shoppingListItems removeObjectAtIndex:indexPath.row];\n [tableView reloadData];\n\n [tableView endUpdates];\n}\n}\n\n\nActually, it's working fine. I can swipe to a row in the table, delete it, i have my fade effect, the content is removed from the database and from the table.\nBut if I try to remove another element just after the first one I have a SIGABRT on\n\n [shoppingListItems removeObjectAtIndex:indexPath.row];\n\n\nIf I move to another tab, go back and remove a row, everything works fine... \nAny ideas?"

"Ruby on Rails: Child Class Gives Parent Class values when child class is created",
"I am basically looking for the opposite of this:\n\nRuby on Rails: Building a child with default values when its parent is created\n\nBut I have not been able to find anything on stack overflow or the documentation to assist me with this.\n\n class GeneralError < Details\n #ASSOCIATIONS\n belongs_to :type\n belongs_to :error_log\n has_one :exception\n\n after_create :create_error_log\n\n def create_error_log\n self.error_log = ErrorLog.new(store_proc: \"Columbia::GeneralError.log\", type_id: 1, summary: \"A general error was logged at: '#{Time.now}\")\n save\n end\nend\n\n\nSo general_errors belongs_to error_log. ErrorLog is also GeneralErrors header table in my database. \n\n\nErrorLog has a column called summary, where I would like to pass in a\nshort description of the error that happened.\nGeneralErrors I have a column named description, where I would like to pass in a longer description of what happened. Ultimately I would like to be able to call GeneralError.new() and pass in both summary AND description.\n\n\nAs of right now, with the code I listed above, I have been able to give ErrorLog default values every time I create a GeneralError. However, those values are hardcoded and not dynamic at all. What's the best, most dry way, to accomplish my task?"

"Nested struct viewer for Linux Kernel",
"I am in the process of tackling the Linux Kernel learning curve and trying to get my head round the information stored in nested struct specifically to resolve a ALSA driver issue.\n\nHence, I am spending a lot of my time in the source code tracing through structures that have pointers to other structures that in turn have pointers to yet other structures...by which time my head has become so full that I start to loose track of the big picture!\n\nCan anybody point me at either a tool or a website (along the lines of the highly usful Linux Cross Reference http://lxr.linux.no/) that will allow me to, ideally graphically, expand down through the nested struct of the source code?\n\nAt the moment we are developing for an Embedded PowerPC in Eclipse CDT version 4.0 but wouldn't be opposed to switching tool chains.\n\nRegards \n\nKermitG"

"How to connect two view controllers to one button in storyboard?",
"Up to now, there is a button in a view controller (let's call it Main View Controller). What I want is: if it satisfies a certain condition, when I press the button, the segue would lead to View Controller A; if not, when I press the button, it would lead to View Controller B.\nBut it seems that one button can only have one segue from it, so I wonder whether what I want is possible to be achieved in storyboard???\nThanks in advance!!!\n\nIf this question is too basic for you, I am so sorry. I am still a very starter in iOS programming."
