"How to Update a record if it exists otherwise insert a new record in MySQL",

"How to simulate an external event during testing at a particular point in code",
"I am trying to work out the best way to simulate something bad happening at very specific points during the execution of code I’m testing, to make sure the code which is supposed to recover from the \"bad thing\" actually works as expected.\n\nIn my particular case I want to simulate a user making detrimental changes to various files, but really any arbitrary example you could think of would apply.\n\nThe simplest way I can think of to do this is to make calls to an empty “stub” method which would do nothing at all in production, but which I will mock out during testing with a patch to do the actual work of making the bad thing happen. In my example the patch would rename or delete files which were being operated on by the script.\n\nConsider the following generic example which is in Python but could be written in any language you'd like:\n\nscript.py:\n\ndef simulate_bad_thing_during_testing():\n # This is an intentionally empty stub to be mocked out during testing.\n pass\n\ndef main():\n # Do some work.\n ...\n\n simulate_bad_thing_during_testing()\n\n # Do some more work, even if bad thing has happened.\n ...\n\n\ntest_script.py:\n\ndef do_bad_thing():\n # Do the bad thing here.\n ...\n\[email protected]('simulate_bad_thing_during_testing', side_effect=do_bad_thing)\ndef test_main_recovers_from_bad_thing():\n main()\n\n # assert all was well and the script recovered from the bad thing.\n ...\n\n\nIs this way of doing it common practice? I've been trying to find examples of this on the net and have failed.\n\nIf others have done it before, then what is it called? Perhaps my Google-fu would be better if I had a better term for this. I've come across \"mutation\" testing and \"fuzz\" testing, but both of those terms seem to denote something different.\n\nIs there a better way to simulate arbitrary worst-case scenarios at particular points in code under test? Perhaps one that won't raise the eyebrows of teammates wondering why I've chosen such an \"invasive\" way of doing this. I do feel slightly uncomfortable with such tight coupling between the implementation of my function and the tests covering the function, but how else can I \"hook\" into a particular line in this fashion?"

"RXJava - continuously emit values for determined period",
"I have a heart-rate sensor that emits a value periodically (anywhere between 500-3000 milli). When the heart rate sensor emits is non-deterministic. With RXJava, i would like to have a constant emitting the 'last seen' heart rate value and the constant emits the value for up to 10 Seconds until it marks it as too-stale & sends a NULL instead. NULL denotes that the heart rate sensor is no longer emitting sensor readings.\nI have the following (kotlin) code:\n val heartRateObservable: Observable<BLEDataValue> = observable\n .flatMap { it.setupNotification(characteristic.uniqueIdentifier) }\n .flatMap { it }\n .map { BTDataPacket(characteristic.uniqueIdentifier, BleParseable(it)).btValue() }.onErrorReturn { BLEDataValueHeartRate(null) }\n return Observable.combineLatest(Observable.interval(1000, TimeUnit.MILLISECONDS), heartRateObservable, BiFunction { _, t2 -> t2 })\n\nQuestion: Is it possible to introduce a way to replay the last seen heart-rate value up to when the last value becomes stale (i.e. after not seeing any heart-rate readings for 10 seconds).. when a heart rate value is seen it replay this until a new heart-rate value arrives OR the timeout of 10 seconds passes as the last value is now too-stale?"

But I don't want to store Bootstrap inside my project folder structure and copy libraries in each project. How can I make IDE know where is libs?\n\nSome approaches I tried.\n\n\nUsing relative paths. @import '../../../../../Bootstrap 3/less/mixins'; does not look good. Moreover, despite import statement is correct (without red underlining), IDE does not \"know\" about imported mixins. When I just copy libraries, IDE \"knows\" about them.\nConnect as JS libs. I see them in project files view. LESS syntax checker cannot locate them, no matter what path i specify. Import statement is underlined with red wavy line.\n\n\nNow, I can use only copy and paste technique or use links (or directory junctions). I am not sure that this is correct way.\n\nI tried this PhpStrom and PyCharm, but I suppose that WebStorm cannot resolve this problem too."

"Modify entity with EntityListener on cascade",
"I have a database in which an entity (say, User) has a list of entities (say, List). As a requirement, I must have a denormalized count of the entities on the list:\n\n@Entity\nclass User {\n /* ... */\n @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)\n private List<Friendship> friends;\n\n public int friendsCount;\n /* ... */\n}\n\n\nWhen I add a new element to the list, I must, transactionally, increase the corresponding counter.\n\nI tried to do so using an EntityListener:\n\nclass MyBrokenEntityListener {\n @PostPersist\n public void incrementCounter(Friendship friendship) {\n friendship.getUser1().incrementFriendsCount();\n }\n}\n\n\nThe entity listener is being correctly called, and while debugging I can see that it correctly modifies the entity. However, Hibernate sends no UPDATE query to the database, only the INSERT query (corresponding to the Friendship entity).\n\nI have tried different events on the EntityListener, but it does not seem to work.\n\nWhat I suppose is happening here is that the entity listener is triggered by an update to the a User. It then identifies all the dirty properties of the user, which consist of the List alone. Therefore it has nothing to do about the User, it has only to insert a Friendship. It then cascades the operation to the Friendship. The entity listener is called, it modifies the user, but at this time Hibernate has already determined that it had not to worry about the user, therefore it does not update the user.\n\nIs this reasoning correct?\n\nIf so, how can I properly achieve this?\n\nThanks,\nBruno"

"Entity Framework Navigation Properties not loading til new DbContext is established",
"I'm still relatively new to EF, so forgive me if I'm missing an obvious concept.\n\nLet me see if I can simplify this...Old question is in edit history, but I think I can distill this down:\n\nFWIW, DbContext is PER REQUEST, not static, which is why the first example works. Not using DI/IoC on the controller at this point.\n\npublic class OrdersController : ApiController {\n private MyDbContext db = new MyDbContext();\n\n //controller methods....\n\n protected override void Dispose(bool disposing) {\n db.Dispose();\n }\n}\n\n\nWorks (2 separate requests):\n\n//request 1: client code sends in a new order to be added to db\npublic Order Post([FromBody]Order order) {\n db.Orders.Add(order);\n db.SaveChanges();\n\n return order;\n}\n\n//request 2: someone punches a button to send an email to CS about this order\npublic void NotifyCustomerService(int orderid) {\n var order = db.Orders.Find(orderid);\n //do email code here\n}\n\n\nBroken (single request):\n\n//request: client code sends in a new order to be added to db AND notifies CS at same time\npublic Order Post([FromBody]Order order) {\n db.Orders.Add(order);\n db.SaveChanges();\n\n //notify CS via email here (nav properties are not populating)\n\n return order;\n}\n\n\nWorks (single request) (but i know this is horrible practice):\n\n//request: client code sends in a new order to be added to db AND notifies CS at same time (using a new dbcontext in the notification code)\npublic Order Post([FromBody]Order order) {\n db.Orders.Add(order);\n db.SaveChanges();\n\n using(var db2 = new MyDbContext()) {\n var sameOrderWTF = db.Orders.Find(order.ID);\n //notify CS via email using sameOrderWTF instance here (nav properties ARE populating)\n }\n return order;\n}\n\n\nSo, it seems to me, that there's some side effect of adding a new never-before-seen entity to the context, and then trying to get it's nav properties to populate. But if you create a new DbContext... even in the same request, it has to directly hit the DB for that entity, not use the in-mem copy, so then the nav properties magically work. That's the part that has me stumped.\n\nWorking Solution\n\n//request: client code sends in a new order to be added to db AND notifies CS at same time\npublic Order Post([FromBody]Order o) {\n Order order = db.Orders.Create();\n db.Orders.Add(order);\n\n //copy values from input to proxy instance\n db.Entry(order).CurrentValues.SetValues(o);\n\n //copy input lines to proxy instance (same process as order for each line)\n o.OrderLines.ToList().ForEach(l => {\n var line = db.OrderLines.Create();\n db.OrderLines.Add(line);\n db.Entry(line).CurrentValues.SetValues(l);\n order.OrderLines.Add(line);\n });\n\n db.SaveChanges();\n\n //notify CS via email here (nav properties are not populating)\n\n return order;\n}\n\n\nSo while we'll consider this question answered (thanks Uber Bot), the need to go through all of that seems more laborious than my other (admittedly short) experience with ASP.NET MVC and EF. I guess maybe I should be using ViewModels and mapping the VM properties to a proxy instance instead of trying to use the EF classes directly, but I just can't really see the benefit for a simple call like this."

"How to convert json schema to avro schema",
"My application has been using json schema (org.everit.json.schema.Schema ) to validate JSON messages whether they comply to a particular format. We are now thinking of moving to the Avro schema. This involves converting previously-stored schema.json files to be converted to Avro schema schema.avsc. Also, the current behavior is we get schema in JSON format via an API /schema/create and store it schema.json format after validating it using SchemaLoader, for example, SchemaLoader.load(JSONObject obj). \n\nWe also need a way to convert this schema.json to schema.avsc as we receive it run time via API. Is there any utility/tool we can use to convert the schema.json to schema.avsc?"

"How can garbage collectors be faster than explicit memory deallocation?",
"I was reading this html generated, (may expire, Here is the original ps file.)\n\nGC Myth 3: Garbage collectors are always slower than explicit memory deallocation.\nGC Myth 4: Garbage collectors are always faster than explicit memory deallocation.\n\nThis was a big WTF for me. How would GC be faster then explicit memory deallocation? isnt it essentially calling a explicit memory deallocator when it frees the memory/make it for use again? so.... wtf.... what does it actually mean?\n\n\n Very small objects & large sparse\n heaps ==> GC is usually cheaper,\n especially with threads\n\n\nI still don't understand it. Its like saying C++ is faster then machine code (if you don't understand the wtf in this sentence please stop programming. Let the -1 begin). After a quick google one source suggested its faster when you have a lot of memory. What i am thinking is it means it doesn't bother will the free at all. Sure that can be fast and i have written a custom allocator that does that very thing, not free at all (void free(void*p){}) in ONE application that doesnt free any objects (it only frees at end when it terminates) and has the definition mostly in case of libs and something like stl. So... i am pretty sure this will be faster the GC as well. If i still want free-ing i guess i can use an allocator that uses a deque or its own implementation thats essentially\n\nif (freeptr < someaddr) {\n *freeptr=ptr;\n ++freeptr; \n}\nelse\n{\n freestuff();\n freeptr = freeptrroot;\n}\n\n\nwhich i am sure would be really fast. I sort of answered my question already. The case the GC collector is never called is the case it would be faster but... i am sure that is not what the document means as it mention two collectors in its test. i am sure the very same application would be slower if the GC collector is called even once no matter what GC used. If its known to never need free then an empty free body can be used like that one app i had.\n\nAnyways, i post this question for further insight."

"What is best practices for syncing service cached Angular 1.3?",
"I am working on a legacy project with angular 1.3 and got stuck on a decision what is the best way to keep service variables and $scope in sync after updating or if receiving the data takes longer than the digest cycle.\n\nI am implementing variable caching in my service, which returns a getter for a variable something like this:\n\nreturn function () {\n if(!this.games)\n {\n this.games= [];\n if(!!this.gameTypeId)\n this.getAll(this.gameTypeId);\n else\n this.getAll();\n };\n return this.games;\n }\n\n\nand if the getAll function takes longer than the digest cycle the view does not update. So a work around is to use $apply, but it feels that I am approaching this the wrong way. Because the promise looks like this:\n\nreturn Resource.query({id: gameTypeId, resourceName: \"Games/ByGameType\"})\n .$promise.then(function(response){\n if(!$rootScope.$$phase) {\n $rootScope.$apply(function () {\n angular.extend(this.games, response);\n });\n }\n else\n angular.extend(this.games, response);\n });\n\n\nAnd you have to check if the $digest cycle really ended (if the promise returns the value faster the the view updates on its own). \n\nThe other way is to sprinkle promise returns all around the controller and update the $scope.games there, on this side the controller gets little bit more crowded. And instead of returning a function in the getter just return a way to rebind $scope.games to service->this.games value. The first way is implemented now and works, but not sure if it is the best way."

"@JsonInclude not working on Deserialization with Spring, using mutable objects",

"Anything similar to Emacs' buffer/window support for Eclipse?",
"I'm trying to make the switch from Emacs to Eclipse. One thing that seems to be missing is its buffer/window support.\n\nI know in Eclipse I can drag an editor's tab title over to split the view, creating the equivalent of a new Emacs window, which is a step in the right direction. \n\nI can't find any key bindings for this functionality, though. Ideally, I'd like to be able to set keys to split horizontal, split vertical, switch to next (there is a next editor, but I want the next window/whatever you call it), switch to previous, close this window split (not this editor), close all other editor window splits.\n\nAs it is, the only way I've found to close a split pane is to drag all the files over one by one until none are left. Things like this make working with split screens tedious in Eclipse.\n\nAny help would be appreciated, hopefully there's something simple I'm missing."

I welcome cleaner, more reliable, and more comprehensive code.\n\ntest1 <- \"colnames(x) <- subset(df, max(y))\" \ntest2 <- \"sat <- as.factor(gsub('International', 'Int'l', sat))\"\ntest3 <- \"score <- ifelse(str_detect(as.character(sat), 'Eval'), 'Importance', 'Rating')\"\ntest <- c(test1, test2, test3)\n\n\nThe test object includes eight functions (colnames, subset, max, as.factor, gsub, ifelse, str_detect, as.character), and the first two twice.

Apparently, they definitely ask one problem on Dynamic Programming? \n\nDoes anyone know of a good resource for collection of DP problems in C along with solutions? I know what DP is & have used it on an occasion or twice. However I feel to crack a DP problem in test, prior practice of typical problems will make it easier to approach.\n\nAny good resources or problem sets with solutions in C will be highly appreciated. Thanks."

"Angular Validation: Access a Form from another Form",
"I have these two simple forms - \n\n<form novalidate name=\"frm1\" class=\"form-horizontal\" role=\"form\">\n <fieldset>\n <div class=\"form-group row\">\n <label for=\"sectionTxt\" class=\"control-label col-sm-2\">Section(s)</label>\n <div class=\"col-sm-2\" ng-class=\"{ 'has-error':lq.section.$error.pattern}\">\n <input type=\"text\" id=\"sectionTxt\" name=\"section\" ng-model=\"query.section\" class=\" col-sm-2 form-control\" ng-pattern=\"/^(\\d)+$/\" />\n </div>\n <div style=\"color:red\" ng-show=\"form1.section.$error.pattern\">Numbers Only Please</div>\n</fieldset>\n</form>\n\n<form novalidate name=\"frm2\" class=\"form-horizontal\" role=\"form\">\n <fieldset>\n <div class=\"form-group row\">\n <button class=\"col-sm-1 col-sm-push-8 btn btn-default\" type=\"submit\" ng-click=\"filterGrid()\" ng-disabled=\"!frm1.$error\">Search</button>\n </div>\n</fieldset>\n</form>\n\n\nForm1 is always null or falsy in form2.\n\nHow do I access form1 from form2 in the ng-disabled directive? I need to inspect whether or not form1 is valid before enabling the submit button in form2.\n\nI'd also prefer to do the validation completely in the markup and not write any JS code in the controller or directives."

"Modifying Date.prototype and binding this",
"Simple task and many questions.\n\nI needed a simple way to display the week day.\nFor this the easiest way was modifying the Date.prototype as follow:\n\nDate.prototype.getWeekDay = function () {\n const weekday = [\"Sunday\", \"Monday\", \"Tuesday\", \"Wednesday\", \"Thursday\", \"Friday\", \"Saturday\"];\n return weekday[this.getDay()];\n}\n\n\nI know, that we generally should avoid modifying prototype. But in this case I don't think that it causes any problems. Am I right? Can I do so? Or is it considering bad coding?\n\nThe second question is regarding the binding the this in arrow functions.\nIf I modify the above function to an arrow function like this:\n\nDate.prototype.getWeekDay = () => {\n const weekday = [\"Sunday\", \"Monday\", \"Tuesday\", \"Wednesday\", \"Thursday\", \"Friday\", \"Saturday\"];\n return weekday[this.getDay()];\n}\n\n\nThe function doesn't work any more, because of the this keyword. I know that I have to bind this but I don't know how to do so. How should I bind this correctly?"

"I have a project which acts as a web bookstore. I have implemented a search which at the moment, only searches books by author.
