"Display logfile before committing transaction. Only commit if user confirms",
"When I update records in the data I want to show the user the update log BEFORE the transaction is committed and give the option to continue or roll back.\n\nThe code that commits the updates to the database follows this format:-\n\n<?php\ninclude 'submitLogger.php';\n\n// Begin logging\nini_set( \"error_log\", $logFile );\nini_set( \"log_errors\", \"On\" );\nini_set( \"display_errors\", \"Off\" );\nerror_log( \"Log file '\" . $logFile . \"' created\" );\n\n// Open the database\n.\n.\n\nerror_log( \"Connect OK\" );\n.\n.\n\nerror_log( \"Transaction started (autocommit OFF)\\n\" ); \n.\n.\n\nerror_log( \"Processing \" . count( $deletes ) . \" item(s) marked for deletion...\" ); \n.\n.\n\n\n// commit changes\nerror_log( \"Committing changes...\" ); \nif ( mysqli_commit( $link ) === false ) {\n mysqli_rollback( $link );\n error_log( \"Commit failed.

"Rails 3: rollback for after_create",
"I have an enrollment form. \n\nWhen the user enrolls, the app is supposed to save the data in the enrollments table and in the users table. (I need this separation because the user's profile can change but the data he entered for that particular enrollment has to be archived. So even if later the user changes his last name, in the enrollment form I'll have his initial information.)\n\nSo I was thinking about saving data in the enrollments table then have a after_create call, like this...\n\nclass Enrollment < ActiveRecord::Base\n\n after_create :save_corresponding_user\n\n def save_corresponding_user\n user = User.new\n user.full_name = self.user_full_name\n user.email = self.user_email\n user.mobile_phone = self.user_mobile_phone\n user.save\n end\nend\n\n\nThe issue is, what if saving the user fails for any reason. How can I rollback and destroy the just saved data from the enrollments table?"

"Consistent DNS between Kubernetes and docker-compose",
"As far as I'm concerned, this is more of a development question than a server question, but it lies very much on the boundary of the two, so feel free to migrate to serverfault.com if that's the consensus).\n\nI have a service, let's call it web, and it is declared in a docker-compose.yml file as follows:\n\n web:\n image: webimage\n command: run start\n build:\n context: ./web\n dockerfile: Dockerfile\n\n\nIn front of this, I have a reverse-proxy server running Apache Traffic Server. There is a simple mapping rule in the url remapping config file\n\nmap / http://web/\n\n\nSo all incoming requests are mapped onto the web service described above. This works just peachily in docker-compose, however when I move the service to kubernetes with the following service description:\n\napiVersion: v1\nkind: Service\nmetadata:\n labels:\n io.kompose.service: web\n name: web\nspec:\n clusterIP: None\n ports:\n - name: headless\n port: 55555\n targetPort: 0\n selector:\n io.kompose.service: web\nstatus:\n loadBalancer: {}\n\n\n...traffic server complains because it cannot resolve the DNS name web.\n\nI can resolve this by slightly changing the DNS behaviour of traffic server with the following config change:\n\nCONFIG proxy.config.dns.search_default_domains INT 1\n\n\n(see https://docs.trafficserver.apache.org/en/7.1.x/admin-guide/files/records.config.en.html#dns)\n\nThis config change is described as follows:\n\n\n Traffic Server can attempt to resolve unqualified hostnames by expanding to the local domain. For example if a client makes a request to an unqualified host (e.g. host_x) and the Traffic Server local domain is y.com, then Traffic Server will expand the hostname to host_x.y.com.\n\n\nNow everything works just great in kubernetes.\n\nHowever, when running in docker-compose, traffic-server complains about not being able to resolve web.\n\nSo, I can get things working on both platforms, but this requires config changes to do so. I could fire a start-up script for traffic-server to establish if we're running in kube or docker and write the config line above depending on where we are running, but ideally, I'd like the DNS to be consistent across platforms. My understanding of DNS (and in particular, DNS default domains/ local domains) is patchy.\n\nAny pointers? Ideally, a local domain for docker-compose seems like the way to go here."

"Do you use particular conventions for naming complementary variables?",
"I often find myself trying to come up with good names for complementary pairs of variables; where two variables denote opposing concepts, two participants in some sort of duologue, and so on.\n\nThis might be better explained by a counter-example - I maintain an app that prints two graphics as part of a print advertisement. They're stored in the database as TopLogo and LowerLogo, which I have to stop and double-check every time I use them because I'm expecting top to complement bottom, and lower should complement upper. \n\nThere's some obvious examples that I think work well:\n\nclient / server\nsource / target for copying/moving data or files from one variable to another\nminimum / maximum \n\nbut there's some concepts that just don't lend themselves to such neat naming schemes. For example, when paging through records, does 'last' mean 'final' or 'previous' ? I recently saw some code that used firstPage, previousPage, nextPage and finalPage to avoid the ambiuous lastPage completely, which I thought was very beat, hence this question.\n\nDo you have any particularly neat variable name pairs you'd care to share with us? (Bonus points if they're the same length, which makes the code so much neater in monospaced fonts.)"

"Custom UICollectionView in Swift 3 not working",

I have checked the Main.storyboard and I think I have named all of my classes correctly and have assigned them to the collectionViewCell and the identifier. I delete this line and it compiles fine, but whenever the app is run nothing shows up on the screen so there may be something wrong with my images too. Does anybody have any ideas? How would you go about creating a custom UiCollection View? Do I have the right idea?"

I am interested specifically in the samples in right half of the device.\n\n\n\nThe app is targeting iOS 11 and is built in Xamarin.iOS and C#. \n\nWhat I have tried already\n\nMy first idea was to utilize built in augmented reality capabilities in iOS to identify the rectangle in scene, but I found out that this will not work as the device is not regular shaped and the available methods have hard time locating it. I also learned it is possible to train a machine learning model to answer the question of whether ColorChecker is in the current screen, but still will not answer the question of where the individual color samples are and how is the device oriented.\n\nI have also found CCFind algorithm using MATLAB, which does find ColorChecker given a photo, but is not fast enough even on powerful PC to be usable as a real-time solution and also MATLAB cannot be ported to iOS, so I tried rewriting the code to OpenCV + C++, which was tedious and I couldn't finish it successfully in almost a month of work.\n\nI am open to any suggestions or tips on how to approach this problem, as I am not very knowledgeable in computer vision area and don't really know where to start."

I have basic Node/Gulp knowledge, but haven't been able to get this running.\n\nLivereload (or a middleware server) should proxy the 'real' URLs, making sure all websites run as they would normally and Livereload should be available over the network (so not just localhost, because that runs on the development server)\n\nDesired result:\n\nLivereload runs on my dev server (IP: 10.0.0.1), my project is called helloworld.dev, I browse to 10.0.0.1:3000 on my machine and see helloworld.dev proxied through Livereload.

"Using wait() vs waitpid() in c",
"So I'm trying to traverse a directory(and subdirectories) and create new processes to sort files and traverse subdirectories. However, I'm having a little trouble understanding how useful my code will be. To my understanding, wait() will sleep the parent process until the child process terminates. Currently my recursive function is \n\nvoid iterate_dir(char* name){\n\n DIR *dd = opendir(name);\n struct dirent *curr;\n\n while((curr = readdir(dd))!=NULL){\n\n if((strcmp(curr->d_name,\".\")==0 || strcmp(curr->d_name,\"..\")==0) && curr->d_type==DT_DIR){\n\n continue;\n\n }\n\n int status = -1;\n int pid = fork();\n\n if(pid==0){\n\n //child process\n if(curr->d_type==DT_DIR){\n\n printf(\"DIRECTORY:\\t%s\\n\", curr->d_name);\n char new_path[strlen(curr->d_name)+strlen(name)+2];\n sprintf(new_path,\"%s/%s\",name,curr->d_name);\n //recurse, iterate sub directory\n iterate_dir(new_path);\n _exit(getpid());\n\n\n }else{\n\n printf(\"FILE:\\t%s\\n\", curr->d_name);\n //sort the file\n _exit(getpid());\n\n }\n\n\n }\n\n wait(&status);\n\n }\n\n closedir(dd);\n\n}\n\n\ngiven and initial directory, it works, but im concerned with the wait() function. I would like the code to continue traversing the directory while the child processes are executing, and currently wait prevents this from happening. But I still need to prevent zombie children. Would using waitpid() instead allow me to have this functionality(ie. allow the loop to continue through the rest of the directory while the child process executes), can I just use 1 wait in main which will prevent all processes created from becoming zombies, or is there a different approach I should take? This is for a school project and I'm required to use fork (not exec) to create a new process for traversing sub directories and a new process for sorting each file."

"json references are not preserved when deserializing data",
"I am trying to load json data into my database. The data is highly structured, and has the potential for numerous elements to be repeated throughout the structure. For repeated elements, I would like to use id's and references so I don't need to duplicate code.\n\nI am currently using json.NET for the deserialization, and I can not get references to deserialize properly. I keep winding up with null values for the elements I try to populate with references.\n\nI have tried structuring the references a myriad of ways, both using id's and using URI syntax. I have gotten the same result no matter how I structure the references.\n\nHere's the c# code I am using for deserialization:\n\nString dir = Directory.GetCurrentDirectory() + \"\\\\wwwroot\\\\json\\\\\";\nString incidentJson = System.IO.File.ReadAllText(dir + \"incident_test.json\");\nIncidentArray incidents = JsonConvert.DeserializeObject<IncidentArray>(\n incidentJson\n ,new JsonSerializerSettings { PreserveReferencesHandling = PreserveReferencesHandling.All }\n);\n\n\nHere's the class I am trying to deserialize the data to:\n\npublic class IncidentArray\n{\n public Incident[] Incidents { get; set; }\n}\n\npublic class Incident\n{\n public Jurisdiction Jurisdiction { get; set; }\n}\n\npublic class Jurisdiction\n{\n public String Code { get; set; }\n public String Name { get; set; }\n public String Description { get; set; }\n}\n\n\nHere's an incident_test.json that parses just fine:\n\n{\n \"incidents\": [\n {\n \"jurisdiction\": {\n \"code\": \"CD\",\n \"name\": \"City Division\",\n \"description\": \"City Division, Portland OR USA\"\n }\n }\n ]\n}\n\n\nAnd here's an incident_test.json with references. The jurisdiction comes out null in the deserialized object:\n\n{\n \"incidents\": [\n {\n \"jurisdiction\": { \"$ref\": \"1\" }\n }\n ],\n \"definitions\": {\n \"jurisdiction\": {\n \"$id\": \"1\",\n \"code\": \"CD\",\n \"name\": \"City Division\",\n \"description\": \"City Division, Portland OR USA\"\n }\n }\n}\n\n\nI would expect the object resulting from the deserialization to populate with the data in the referenced json data. As previously stated, I'm getting null instead.\n\nRESOLVED: desmondgc definitely pointed me in the right direction with his answer below, but there's a little more to it than object order. I did some more testing considering object order and placement. This deserializes and captures the reference:\n\n{\n \"incidents\": [\n {\n \"jurisdiction\": {\n \"$id\": \"1\",\n \"code\": \"CD\",\n \"name\": \"City Division\",\n \"description\": \"City Division, Portland OR USA\"\n }\n },\n {\n \"jurisdiction\": { \"$ref\": \"1\" }\n }\n ]\n}\n\n\nand if I construct the deserializer like this:\n\nIncidentArray incidents = JsonConvert.DeserializeObject<IncidentArray(\n incidentJson\n ,new JsonSerializerSettings {\n PreserveReferencesHandling = PreserveReferencesHandling.All\n ,MetadataPropertyHandling = MetadataPropertyHandling.ReadAhead\n }\n);\n\n\nThis works too:\n\n{\n \"incidents\": [\n {\n \"jurisdiction\": {\n \"code\": \"CD\",\n \"name\": \"City Division\",\n \"$id\": \"1\",\n \"description\": \"City Division, Portland OR USA\"\n }\n },\n {\n \"jurisdiction\": { \"$ref\": \"1\" }\n }\n ]\n}\n\n\ndue to the MetadataPropertyHandling property.\n\nObviously, order matters here, and in my original test data the order was wrong. Another important factor, however, seems to be the fact that in my initial test json, the object with the reference id was not actually being deserialized because it did not match the structure of the object I was deserializing to. As a result, there was no object to copy into the reference object when the deserializer was trying to process it.\n\nSo order matters, but object structure matters as well. The id property has to mark an object that the deserializer will process, and the reference object has to be in a place in the object graph where the deserializer recognizes it as the same type as the original object."

"Retrieving and processing a server side value from XML at runtime",
"I am trying to implement a solution to updating what a user control displays without republishing the user control itself. The UC gets xml from an external file as its content rather than storing the content in the control, so the xml is what is republished instead of the UC.\n\nThe issue is that I also have a need for the content to contain inline variables such as <% =myvariable %>. Is there a way to retrieve the xml and then run that also at runtime instead of treating it as text?\n\nThe following is just a rudimentary example with only the basics related to this issue specifically, not the full extent of the code on the page, but hopefully it is enough to illuminate what I am asking.

"How do you fool a window into believing it has focus?",
"I have been trying to send mouse clicks to a WebBrowser control inside of my form using PostMessage(), and I have run into a rather significant issue. What I am trying to achieve is to simulate mouse clicks on this WebBrowser while my form is minimized. Usually PostMessage() would work just fine doing this, but it seems that it only works while my form has focus. This leads me to believe that there is some check going on to see if the particular website I am loading into my WebBrowser control is in focus before it handles mouse events.\n\nThis is how I send the clicks with my program:\n\nprivate void SendClick(Point location)\n { \n resetHandle = true;\n StringBuilder className = new StringBuilder(100);\n while (className.ToString() != \"Internet Explorer_Server\") \n {\n handle = GetWindow(handle, 5); // 5 == child\n GetClassName(handle, className, className.Capacity);\n //MessageBox.Show(className.ToString());\n }\n IntPtr lParam = (IntPtr)((location.Y << 16) | location.X); \n IntPtr wParam = IntPtr.Zero; \n const uint downCode = 0x201; \n const uint upCode = 0x202;\n const uint moveCode = 0x200;\n PostMessage(handle, moveCode, wParam, lParam); //move mouse\n PostMessage(handle, downCode, wParam, lParam); // mousedown\n PostMessage(handle, upCode, wParam, lParam); // mouseup\n }\n\n\nThis is what the resetHandle does:\n\nprivate void timer3_Tick(object sender, EventArgs e)\n {\n if (resetHandle == true)\n {\n handle = webBrowser1.Handle;\n resetHandle = false;\n }\n }\n\n\nI'm not sure if there is a better way of sending mouse events to a background window and I am open to any ideas.

"Dependency Injection - Is it better to pass a complete class, or the name of a class?",
"For dependency injection, I understand that I have to pass an instance of one class to the main instance instead of the main class creating it's own instance, like so (php):\n\nclass Class_One {\n protected $_other;\n public function setOtherClass( An_Interface $other_class ) {\n $this->_other_class = $other_class;\n }\n public function doWhateverYouHaveToDoWithTheOtherClass() {\n $this->_other_class->doYourThing();\n }\n}\n\ninterface An_Interface {\n public function doYourThing();\n}\n\nclass Class_Two implements An_Interface {\n public function doYourThing() { }\n}\n\nclass Class_Three implements An_Interface {\n public function doYourThing() { }\n}\n\n\n// Implementation:\n$class_one = new Class_One();\n$class_two = new Class_Two();\n$class_three = new Class_Three();\n$class_one->setOtherClass( $class_two );\n$class_one->doWhateverYouHaveToDoWithTheOtherClass();\n$class_one->setOtherClass( $class_three );\n$class_one->doWhateverYouHaveToDoWithTheOtherClass();\n\n\nThis is all fine. I know that since both Class_Two and Class_Three both implement An_Interface, they can be used interchangeably in Class_One. Class_One wouldn't know the difference between them.\n\nMy question is, is it ever a good idea to, instead of passing an instance to setOtherClass, pass a string such as \"Class_Two\", and have Class_One's setOtherClass method actually create the instance itself like so:\n\nclass Class_One {\n ...\n public function setOtherClass( $other_class_name ) {\n $this->_other_class = new $other_class_name();\n }\n ...\n}\n\n\nDoes this sort of defeat the purpose of Dependency Injection, or is this completely valid? I thought this type of set up may help me with configuration, where a user can specify which class he wants to use in a string earlier on and this can later be passed to the Class_One..\n\nActually, writing this out has made me think that it's probably not a good solution, but I'll still post this in case someone can give me some good feedback on why I should/shouldn't do this.\n\nThanks =)\n\nRyan"
