"Apache mod_security and chat server",

So what is the best practice to handle the \"refreshing\" of those URLs?\n\nThings I thought about:\n\n\nHaving a cron job in my backend that checks every e.g. every 24 hours if I have any URLs going invalid within the next 24h and generate a new one in case.\nChecking it everytime I receive a GET request and re-generate if it's invalid\nNot checking at all on the backend, and just try to the hit the URL on the frontend and if I get a 403 to then request the re-generation from the backend.

"Qt Drag & Drop doesn't work fine with custom items",
"I'm building a GUI using PySide2 (Qt5) with a custom treeview widget (MyTreeView, inherited from QTreeView).

There is information here (https://docs.microsoft.com/en-us/azure/active-directory/develop/msal-js-pass-custom-state-authentication-request) about doing it with MSAL.js, but it doesn't seem directly transferable to MSAL.Net.

"Moving from Mercurial to Git and merging with custom changes",
"I am having a problem with moving from Mercurial to Git and merging the last version of nopCommerce with my changes.\n\nHere is what I did. I clonned the nopCommerce mercurial repository a long time ago (version 2.60 I think). Since then I made many changes to the platform and I merged them with newer versions of nopCommerce. The last merge I did was on version 3.10.\n\nNow I see that nopCommerce started using Git, so I converted my mercurial repository to Git (following this guide: http://arr.gr/blog/2011/10/bitbucket-converting-hg-repositories-to-git/). But now, when I pull the nopCommerce changes (up to version 3.50), I get the following: \"warning: no common commits\", and ALL the commits are downloaded (not just the new ones, from 3.10 to 3.50), although I already have the commits up to version 3.10 in my repository. Basically, the nopCommerce commits up to version 3.10 are duplicated. I think this happens, because they have different commit numbers (when I converted my mercurial repository to Git, the commits got different commit numbers, and I see that the new nopCommerce Git repository also has different commit numbers from the old Mercurial repository).\n\nThe problem is that, when I merge nopCommerce v3.50 with the changes I made, and try to resolve the conflicts, the BASE file is empty, because Git does not see that they have a common ancestor. The LOCAL file has the commits from my repository as ancestors and the REMOTE file has the commits from the new Git repository as ancestors.\n\nDo you have any idea of how to fix this problem?"

So I felt to share the problem that I encountered. \n\nI was learning Exception Handling in Java and was practising program of same. When I used throws keyword with method to indicate about Exception to its caller method I got an error saying No exception of type Exception can be thrown; an exception type must be a subclass of Throwable. However while using throws for indicating Throwable and RunTimeException, there was no any error. It confused me as why Throwable is not giving any error but Exception is. Anyhow I made my own conclusion from this, that we cant use throws to indicate Exception.\n\nI conveyed same thing to one of my Bro and he disagreed with me and we had debate about this, finally he told he will execute and show and I was sure that it will give error, but to my surprise when he executed same piece of code in which I got error, he didn't got any. It surprised me like how this can happen.\n\nThen I came to know there might be some problem with my Eclipse Version so I installed previous version of Eclipse and tried with same piece of code and voila there was no error.\n\nStill I am confused either its my mistake or is this any bug with Eclipse but how there can be bug with release version?

"How to get selected table view cell row in segue?",
"I am developing an iOS app using Swift and I have a view controller that segues from a table view cell content view by selecting a cell row or selecting a button inside of that cell row's content view. The original view controller that contains the table view performs a segue on two different occasions: one segue when the cell row itself is selected (segues to an avplayerviewcontroller and plays a video depending on the cell row that was selected) and the second segue happens when you press a button that is inside of the content view of the table view cell. In the first segue, I am able to pass the the cell row that is selected with if let indexPath = self.tableview.indexPathForSelectedRow when I override the first segue. However when I try to pass the cell row that was selected when I try to override the second segue that happens when you press the button it doesn't work. Is this because the button inside of the table view cell doesn't know which row it was selected in? If so, how can I solve this problem, and if not what is a viable solution to solve such issue? Reminder: The \"playDrill\" segue is trigged when you select a cell row, the \"Tips\" segue is trigged when you selected a button inside of that same cell row's content view\n\nCode for first segue that happens when you select a cell row (this segue functions as desired):\n\nclass DrillsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {\n\n override func prepare(for segue: UIStoryboardSegue, sender: Any?) {\n\n if segue.identifier == \"playDrill\" {\n if let indexPath = self.tableView.indexPathForSelectedRow {\n if initialRow == 1 {\n drillVid = videoURL[indexPath.row]\n playerViewController = segue.destination as! PlayerController\n playerViewController.player = AVPlayer(playerItem: AVPlayerItem(url: drillVid))\n playerViewController.player?.play()\n print(indexPath) //prints correct value which is \"[0,6]\"\n }\n if initialRow == 3 {\n drillVid = videoUrl[indexPath.row]\n playerViewController = segue.destination as! PlayerController\n playerViewController.player = AVPlayer(playerItem: AVPlayerItem(url: drillVid))\n playerViewController.player?.play()\n }\n\n\nCode for second segue that triggers when you select a button inside of the cell's content view (I want this segue to have the value of indexPath as in the first segue, but when I try to use that code it doesn't return the correct value):\n\n override func prepare(for segue: UIStoryboardSegue, sender: Any?) {\n\n if segue.identifier == \"Tips\" {\n if let indexPath = self.tableview.indexPathForSelectedRow {\n if initialRow == 1 {\n print(indexPath) //the value printed is \"6\", I want \"[0,6]\" like the first code block\n let tipVC = segue.destination as!

"loadable levels with code in addition to assets in xamarin",
"I am a newbie to Xamarin, and I have searched SO and Google for this but I have not found the right query to get my answer. In flex, I can create a \"module\" and it can have assets, code, etc, and in that module I can implement a class based on an interface in the main app, and load it after the main app is loaded.\n\nIn a game that I have written I load my levels this way. It works great because the core app is totally independent and rarely requires updates.\n\nBasically imagine that the main app has an IGameEngine interface for any interaction with it, and each level that is loaded from the cloud and cached locally (like Angry Birds Seasons does with levels), will have an implementation of that IGameEngine which may or may not be the same or different from other levels, depending on the features needed in that level.\n\nI will be using xamarin because I am comfortable with C# and have a need to target all platforms, and thus need to minimize the code to do so. I will most likely also be using CocosSharp as it seems to be an active community.\n\nIn Xamarin can I do something similar? How? When I search for Xamarin \"modules\", I get a million results for how to include a module in the compiler, obviously I'm searching for the wrong keywords.\n\nSorry for a question that an experienced user could probably locate in 5 seconds on Google, but I don't know where to start.

I'm using spark 2.4 with json lib so I read jsons as \nspark.read.json(\"jsonfile\")\n\nI'm flattening my json schema to this kind of format where col name is: \nB__C \nB__somedifferentColname\n\nSample json look like this \n\n{\n \"A\":[\n {\n \"B\":{\n \"C\":\"Hello There\"\n }\n },\n {\n \"B\":[\n {\n \"C\":\"Hello\"\n },\n {\n \"C\":\"Hi\"\n }\n ]\n }\n ]\n}\n\n\nand I would like to have this json in format like this: \n\n{\n \"A\":[\n {\n \"B\":[{\n \"C\":\"Hello There\"\n }]\n },\n {\n \"B\":[\n {\n \"C\":\"Hello\"\n },\n {\n \"C\":\"Hi\"\n }\n ]\n }\n ]\n}\n\n\nSo as you can see what I have changed is added square brackets to first object.\n\nBut when I have one value as struct type and one value as a list it puts this to string so the column value will be look like:\n\n\"[{\"C\":\"Hello\"},{\"C\":\"Hi\"}]\"\n\nand it should look like that \nB__C\nHello\nHi\nHello There\n\nIs anyone able to help me what trick I can use to resolve this issue? \nTeam which delivers jsons to us said this is not possible to do this from thier side so we have to resolve this on our side."
