"Average progress of all the NSURLSessionTasks in a NSURLSession",
"An NSURLSession will allow you to add to it a large number of NSURLSessionTask to download in the background. \n\nIf you want to check the progress of a single NSURLSessionTask, it’s as easy as\n\ndouble taskProgress = (double)task.countOfBytesReceived / (double)task.countOfBytesExpectedToReceive;\n\nBut what is the best way to check the average progress of all the NSURLSessionTasks in a NSURLSession? \n\nI thought I’d try averaging the progress of all tasks:\n\n[[self backgroundSession] getTasksWithCompletionHandler:^(NSArray *dataTasks, NSArray *uploadTasks, NSArray *allDownloadTasks) {\n\n double totalProgress = 0.0;\n\n for (NSURLSessionDownloadTask *task in allDownloadTasks) {\n\n double taskProgress = (double)task.countOfBytesReceived / (double)task.countOfBytesExpectedToReceive;\n\n if (task.countOfBytesExpectedToReceive > 0) {\n totalProgress = totalProgress + taskProgress;\n }\n NSLog(@\"task %d: %.0f/%.0f - %.2f%%\", task.taskIdentifier, (double)task.countOfBytesReceived, (double)task.countOfBytesExpectedToReceive, taskProgress*100);\n }\n\n double averageProgress = totalProgress / (double)allDownloadTasks.count;\n\n NSLog(@\"total progress: %.2f, average progress: %f\", totalProgress, averageProgress);\n NSLog(@\" \");\n\n}];\n\n\nBut the logic here is wrong: Suppose you have 50 tasks expecting to download 1MB and 3 tasks expecting to download 100MB. If the 50 small tasks complete before the 3 large tasks, averageProgress will be much higher than the actual average progress. \n\nSo you have to calculate average progress according to the TOTAL countOfBytesReceived divided by the TOTAL countOfBytesExpectedToReceive. But the problem is that a NSURLSessionTask figures out those values only once it starts, and it might not start until another task finishes. \n\nSo how do you check the average progress of all the NSURLSessionTasks in a NSURLSession?"

"\"Execute Code First Migrations\" checkbox disappeared from my publish profile",
"I'm using web deploy to deploy an MVC4 application using EF5 code first. I made a publish profile called \"development\" that uses web deploy for application and database using the 'Execute Code First Migrations' checkbox to run migrations on application startup. The publishing worked great for a while. At some point I added a new publish profile called \"test\" to deploy to another server, which uses the ftp method of deploy and no automatic migrations. This works fine too. However, when I tried to use my old \"development\" publish profile again, VS changes the settings automatically to the dbDacFx way ('Update database' checkbox instead of 'Execute Code First Migrations') and I can't get it back to the way it was.\nThere were some other changes to the project while using the 'Test' profile, but nothing that seems to me like it could cause this. Does anyone know why VS thinks my project doesn't use code first anymore?"

"The Problems\nAxis 1.4 & JDK 14\nI'm trying to update our application from Java 8 to Java 14, and in doing so, I discovered that Axis 1.4 seems to generate client code that is no longer valid for the newer version of Java.\nThe issue boils down to Axis' use of com.sun.net.ssl.internal.ssl.Provider... when running on JDK 14, this throws a NoClassDefFoundError:\nCaused by: java.lang.NoClassDefFoundError: com/sun/net/ssl/internal/ssl/Provider\n\nRPC/encoded WSDLs\nThe WSDls that I'm trying to parse are from a 3rd party, and unfortunately they are RPC/encoded, which I didn't know until now, is a legacy, seemingly no longer supported, WSDL format.\nThus, my journey to find an alternative to Axis 1.4 - which gladly handles the legacy RPC/encoded format due to it being a very outdated library itself.\n\nThe Attempted Solutions\nLooked For Replacement Jar\nMy first thought, was to research whether or not the com.sun.net.ssl.internal.ssl.Provider lives in a jar in maven central... similar to how some of the other built-in packages were moved to external jars in Java's more recent versions. I found that the package was removed as part of JDK-8218932, but my research fell short, and wasn't able to find a recommended dependency that I could use in it's place.\nOther WSDL to Java Methods\nNext I tried to use some of the other WSDL to Java generators that I found... Unfortunately, they all seem not to support the legacy RPC/encoded format that this 3rd party WSDL is.\njavaws-maven-plugin\n[ERROR] "Use of SOAP Encoding is not supported.\nSOAP extension element on line 46 in file:/<path>/wsdl/kas.wsdl has use="encoded" "\n\ncxf-codegen-plugin\nExecution kas of goal org.apache.cxf:cxf-codegen-plugin:3.3.7:wsdl2java failed:\nRpc/encoded wsdls are not supported with CXF\n\nAxis 2\nDidn't bother attempting, because it clearly states on their website:\n\nNote that Axis2 currently does not support the rpc/encoded style.\n\nAsk The 3rd Party to Update WSDLs\nI plan on reaching out to the 3rd party to see if they could update their WSDLs... however, they seem to currently be generated with Axis 1.3 as they have:\n<!--WSDL created by Apache Axis version: 1.3\n\nI'm not sure how to present to them exactly what they need to do in order to switch their system to a more recent style of WSDL. Additionally, I don't have much confidence in them being willing to change since they have multiple different versions we integrate with, and this would affect all their other clients that have integrations.\n\nThanks\nAny suggestion will be greatly appreciated"

"I'm working on a project to investigate the possibility of adding touch support to an application and so far the findings have been somewhat disappointing. My company uses Scientific Linux 6.4 (Linux kernel 2.6.32) and so far, I've found information suggesting that 2.6.30+ supports multi-touch HID, but I've also seen information suggesting that the multi-touch in this kernel doesn't work with Xorg interfaces.\n\nPutting aside market availability of touchscreens that are compatible with Linux, is there a way we can verify whether or not multi-touch inputs are generated on the system? We have an older ViewSonic touchscreen that has multi-touch capability, and after looking at the output from the evtest tool, I didn't notice any multi-touch events, but I don't know whether evtest is reading the touch events from X or the hardware level.\n\nI have no experience dealing with hardware programming or device drivers, so if anyone could give me some guidance on how to verify multi-touch HID compatibility with our version of Linux, whether we have to write our own driver, or read raw data from somewhere, any information you could provide would be great.\n\nEDIT: The evtest program lists supported events for the device and I don't see anything related to multi-touch, so it doesn't seem like it's supported, but is this an issue with the kernel, the specific device, or something else? The specific monitor I'm testing is a ViewSonic, which is listed as a \"Quanta Optical Touchscreen\" device. I saw somewhere that a driver for Quanta was added in 2.6.34.

"EC2 Instance error telling me multiple IAM Roles are attached when I try to change it...?",

Then I back out to view all instances, mark the checkbox for the instance in question, go to Actions -> Security -> Modify IAM Role, and it shows me a different role, role Y. I then try to set it to No IAM Role (or any various role), and I get this error:\n"Multiple roles associated to instance\nThe selected instance has more than one IAM role associated. This usually occurs when the instance is in the process of replacing an existing instance profile association.

"QuillJS: Howto add format for stroke color",
"In a quill 1.3.7 editor I'd like to add a button to select the stroke color.\nWhat I tried is this: Copied this https://github.com/quilljs/quill/blob/develop/formats/color.js and replaced most "Color" by "Stroke":\nimport Quill from 'quill';\nconst Parchment = Quill.import('parchment');\nclass StrokeAttributor extends Parchment.Attributor.Style {\n value(domNode) {\n let value = super.value(domNode);\n if (!value.startsWith('rgb(')) return value;\n value = value.replace(/^[^\\d]+/, '').replace(/[^\\d]+$/, '');\n const hex = value.split(',').map(component => `00${parseInt(component, 10).toString(16)}`.slice(-2)).join('');\n return `#${hex}`;\n }\n}\nconst StrokeClass = new Parchment.Attributor.Class('stroke', 'ql-stroke', {\n scope: Parchment.Scope.INLINE,\n});\nconst StrokeStyle = new StrokeAttributor('stroke', '-webkit-text-stroke-color', {\n scope: Parchment.Scope.INLINE,\n});\nQuill.register(StrokeClass, true);\nQuill.register(StrokeStyle, true);\n\nThe toolbar container options are extended this way: this.colors = [{ 'color': [] }, { 'stroke': [] }, { 'background': [] }];\nThe result is a button without options:\n\nAdding color values like this this.colors = [{ 'color': [] }, { 'stroke': ['#888888'] }, { 'background': [] }]; also does not show selectable color options.\nAnother idea to create a Stroke Selector is like this example: https://github.com/quilljs/quill/blob/develop/formats/italic.js:\nimport Quill from 'quill';\nconst Parchment = Quill.import('parchment');\nconst BackgroundClass = Quill.import('attributors/class/background');\n\nclass StrokeClass extends BackgroundClass {};\nStrokeClass.attrName = 'stroke';\nStrokeClass.keyName = 'ql-stroke';\n\nclass StrokeStyle extends BackgroundStyle {};\nStrokeStyle.attrName = 'stroke';\nStrokeStyle.keyName = '-webkit-text-stroke-color';\n\nQuill.register(StrokeClass, true);\nQuill.register(StrokeStyle, true);\n\nBut this shows an error: Uncaught TypeError: Class extends value #<ClassAttributor> is not a constructor or null\nWhat works is this (unfortunately not thoroughly as it should): when setting attribute values directly at BackgroundClass then the formatting works (as long as there is the -webkit-text-stroke-width set in the overall CSS):\nimport Quill from 'quill';\nconst BackgroundClass = Quill.import('attributors/class/background');\nconst BackgroundStyle = Quill.import('attributors/style/background');\nBackgroundClass.keyName = 'ql-stroke';\nBackgroundStyle.keyName = '-webkit-text-stroke-color';\n\nAs not every browser supports -webkit-text-stroke-width (https://developer.mozilla.org/de/docs/Web/CSS/-webkit-text-stroke-width) the Quill extension ideally sets the style property -webkit-text-stroke and assembles the value with e.g. 1px [selected colorname] or 0px if there is no color selected.

"I'm trying write a function that would be able to parse out a file with defined messages for a set of replies but am at loss on how to do so.\n\nFor example the config file would look:\n\n[Message 1]\n1: Hey\n How are you?\n2: Good, today is a good day.\n3: What do you have planned?\n Anything special?\n4: I am busy working, so nothing in particular.\n My calendar is full.\n\n\nEach new line without a number preceding it is considered part of the reply, just another message in the conversation without waiting for a response.\n\nThanks\n\nEdit: The config file will contain multiple messages and I would like to have the ability to randomly select from them all.

"Reading JSON objects in Powershell",
"I need to integrate a JSON file which contains paths of the different objects in a PS script that generates and compares the hash files of source and destination. The paths in the JSON file are written in the format that I have stated below. I want to use the paths in that manner and pipe them into Get-FileHash in PowerShell. I can't figure out how to integrate my current PowerShell script with the JSON file that contains the information (File Name, full path) etc.\nI have two scripts that I have tested and they work fine. One generates the MD5 hashes of two directories (source and destination) and stores them in a csv file. The other compares the MD5 hashes from the two CSV files and generates a new one, showing the result(whether a file is absent from source or destination).\nNow, I need to integrate these scripts in another one, which is basically a Powershell Installer. The installer saves the configurations (path, ports, new files to be made etc etc) in a JSON format. In my original scripts, the user would type the path of the source and destination which needed to be compared. However, I now need to take the path from the JSON configuration files. For example, the JSON file below is of the similar nature as the one I have.\n{\n"destinatiopath": "C:\\\\Destination\\\\Mobile Phones\\\\"\n"sourcepath": "C:\\\\Source\\\\Mobile Phones\\\\"\n"OnePlus" : {\n"files": [\n{\n"source": "6T",\n"destination: "Model\\\\6T",\n]\n}\n"Samsung" : {\n"files": [\n{\n"source": "S20",\n"destination": "Galaxy\\\\S20",\n}\n]\n\nThis is just a snippet of the JSON code. It's supposed to have the destination and source files. So for instance if the destination path is: C:\\\\Destination\\\\Mobile Phones\\\\ and the source path is C:\\\\Source\\\\Mobile Phones\\\\ and OnePlus has 6T as source and Model\\\\6T as destination, that means that the Powershell Installer will have the full path C:\\\\Destination\\\\Mobile Phones\\\\Model\\\\6T as the destination, and C:\\\\Source\\\\Mobile Phones\\\\6T as the source. The same will happen for Samsung and others.\nFor now, the MD5 hash comparison PS script just generates the CSV files in the two desired directories and compares them. However, I need to check the source and destination of each object in this case. I can't figure out how I can integrate it here. I'm pasting my MD5 hash generation code below.\nGenerating hash\n#$p is the path. In this case, I'm running the script twice in order to get the hashes of both source and destination. \n#$csv is the path where the csv will be exported. \nGet-ChildItem $p -Recurse | ForEach-Object{ Get-FileHash $_.FullName -Algorithm MD5 -ErrorAction SilentlyContinue} | Select-Object Hash,\n @{\n Name = "FileName";\n Expression = { [string]::Join("\\", ($_.Path -split "\\\\" | Select-Object -Skip ($number))) }\n } | Export-Csv -Path $csv"

"GridView paging always shows first page",
"I´m having a weird experience with paging on a GridView.\nI´m trying to lazy load data into my griview by using an updatepanel with a timer and updateprogress attached to it.\nSo basicly what I´m trying to do is when the page with the grid loads I start the timer by enabling it. In the timer_tick event I´m fetching the data and load that into a variable. Then calling databind on the gridview forcing it to bind the data. Here I´m using a LinqDataSource to do that. Lastly I´m updating the UI via the Update method on the updatepanel. \n\nThis all works fine with sorting and filtering on the gridview but when I´m paging it the grid pages like it should but the paging template always stays on the first page (show 1 as active). Any ideas people? Here is some of my code:\n\n <asp:LinqDataSource runat=\"server\" ID=\"OrdersDataSource\" \n OnSelecting=\"OrdersDataSource_Selecting\" AutoPage=\"false\" />\n\n <asp:GridView runat=\"server\" ID=\"OrdersGridView\" AutoGenerateColumns=\"false\" \n DataSourceID=\"OrdersDataSource\"\n AllowPaging=\"true\" AllowSorting=\"true\" PageSize=\"3\">\n\n <Columns>\n\n\n...\n\n<asp:Timer runat=\"server\" ID=\"LazyLoadUpdatePanel\" \n Enabled=\"false\"\n Interval=\"1\" OnTick=\"LazyLoadUpdatePanel_Tick\" />\n\n\n...\n\nprotected void LazyLoadUpdatePanel_Tick(object sender, EventArgs e)\n{\n if (datasource == null)\n {\n System.Threading.Thread.Sleep(2000);\n datasource = customer.Orders;\n OrdersGridView.DataBind();\n OrdersUpdatePanel.Update();\n\n }\n LazyLoadUpdatePanel.Enabled = false;\n}\n\n\nBTW I have tried with autopaging on the datasource and without it. That didn´t do the trick. As I said the paging seems to work, the UI just isn´t showing what it i supposed to."

"How to use NLog to write multiple \"data\" files",
"I would like my application to repeatedly write a large amount of data to separate \"log\" files during the application lifetime. (Call each instance of such a file a \"data file\".) The data is written to this file in a single write operation (as it's a string). In the main application log file, the application would write the path name of the data file that it creates, so that I can identify that data file that was created at that point in its execution.\n\nI could create the data file using the .NET file API, but I thought it would be useful to use NLog, as I could enable the writing of the file via configuration. However, I cannot see how to define a Target whose name is unique for each write operation. As an alternative, I could programmatically create a Target and add it to the LogManager's Configuration object each time I write a data file, and then delete the Target afterwards.\n\nThis seems plausible, but before implementing it I'd like to know if others had a similar requirement and how they implemented it."

"C++, determine prime number",

I've wanted it to find out if a given number is a prime number or not.\n\nI've got 2 questions about it.\n\n\nI know my method is everything else than good. The programm is checking every single number which makes the programm big. What would be the ideal way to do this? Doesn't matter if I understand your answer yet, I'll simply read up the commands later :).\nI've had a huge problem with the \"Result+=1\" line. At first I had i=1, which gave me the following result for the number 7.\n\n1111112\n\n\nWell, I also know why. For the 6 first for loops he found one number (1) and for the last one 2(1,7).

How do I do that?\n\nThe code:\n\n#include <iostream>\nusing namespace std;\n\n\n\n// Hauptprogramm\n\nint main ()\n{\n // Variablen\n int Prime_number;\n int Result = 0;\n\n // Abfragen\n cout << \"Please enter possible prime number: \";\n cin >> Prime_number;\n\n // Rechnen\n for (int i=2; i <= Prime_number ; i++)\n { \n if (Prime_number%i == 0)\n { \n Result +=1;\n }\n }\n\n // Ausgabe\n if(Result == 1)\n {\n cout << \"You got a prime number!\" << endl;\n }\n else\n {\n cout << \"No luck\" <<endl;\n }\n\n return 0;\n}"
