| PySpark Leverage Function on MapType Column Values Posted: 22 Oct 2021 07:57 AM PDT Below is a dataframe that represents what I'm trying to accomplish. Please note though, that the function I want to leverage is a bit more complex than this example. import pyspark from pyspark.sql import SparkSession #spark = SparkSession.builder.appName('pyspark-by-examples').getOrCreate() arrayData = [ ('1',{1:100,2:200}), ('1',{1:100,2:None})] df=spark.createDataFrame(data=arrayData, schema = ['id','value'])
What I'd like to do is to leverage withColumn to create a new column with a new map typeobject that a function has been applied to. Let's say I wanted to square every value. I know I can create a udf that multiplies values by 2 and use withColumn... However that doesn't appear to work with applying to the MapType. The output I'm trying to achieve is: arrayData = [ ('1',{1:200,2:200},{1:400,2:400}), ('1',{1:100,2:None},{1:200,2:None})] df=spark.createDataFrame(data=arrayData, schema = ['id','value','newCol'])
Lastly, I need to maintain parallelism and am trying to avoid explode as I want to keep it in a single row.  |
| InvalidArgumentException when a binding is configured but not used Posted: 22 Oct 2021 07:57 AM PDT Symfony throw an InvalidArgumentException when a binding is configured but not used by any service $services->defaults() ->autowire() ->autoconfigure() ->bind('$logger_aws', service('logger.aws'));
A binding is configured for an argument named "$logger_aws" under "_defaults" ..., but no corresponding argument has been found. It may be unused and should be removed, or it may have a typo.
Why can't we make some binding available but not used ? Any known workaround ? Thanks  |

For the creation I have ArticleInputModel, and for displaying the details view, I have ArticleDetailsModel, and for update I have ArticleUpdateModel (etc....) However those models have the same properties. - Should I separate this much if it means repetitions of code?

| Calling Fortran from C# in VS2019 with iFort Posted: 22 Oct 2021 07:56 AM PDT I am trying to call Fortran code from C#. I am using Visual Studio 2019 and the Intel Fortran Compiler (iFort). I created a fortran DLL project with the following code that compiles without issue (project set to 'release', 'x64'): module Fortran_DLL_Lib implicit none contains subroutine adder(a,b,x,y) !DEC$ ATTRIBUTES DLLEXPORT, ALIAS:'adder' :: adder !DEC$ ATTRIBUTES REFERENCE :: x,y implicit none integer, intent(in) :: a,b integer, intent(out) :: x,y y = a + b x = 2*a+3*b end subroutine end module
I then created a C# console application with the following code (project also set to 'Release', 'x64'): using System; using System.Runtime.InteropServices; namespace Call_Fortran_Dll_FromCS_Test { class Program { [DllImport("Fortran_DLL_Lib.dll", CallingConvention = CallingConvention.Cdecl)] public static extern void adder(int a, int b, [Out] int x, [Out] int y); static void Main(string[] args) { int a = 4; int b = 3; int x = 0; int y = 0; Console.WriteLine(a); Console.WriteLine(b); Console.WriteLine(x); Console.WriteLine(y); adder(a, b, x, y); //error occurs here Console.WriteLine(a); Console.WriteLine(b); Console.WriteLine(x); Console.WriteLine(y); Console.ReadKey(); } } }
The program runs up until the line that calls the fortran function, then returns the error Exception thrown: 'System.DllNotFoundException' in Call_Fortran_Dll_FromCS_Test.dll An unhandled exception of type 'System.DllNotFoundException' occurred in Call_Fortran_Dll_FromCS_Test.dll Unable to load DLL 'Fortran_DLL_Lib.dll' or one of its dependencies: Access is denied. (0x80070005 (E_ACCESSDENIED))
I have copied both the 'Fortran_DLL_Lib.dll' and 'Fortran_DLL_Lib.lib' files into both the folder that contains the c# project files, as well as the location where the executable project is located, neither seems to help/matter. This is just based on example code I found trying to find ways to do this and isn't specific to what I'm doing. I'm just trying to get a 'proof of concept' together before jumping into more complex applications. The solution doesn't even necessarily be a DLL, that's just what I saw people recommending as the solution to this (in 7+ year old questions on this site). Open to any solutions that successfully call Fortran code from a C# project (eventually, a C# project with a WPF GUI, if that matters). I am in a situation where I can't install Dependency Walker, change environment variables, or pretty much anything that requires elevated privileges. Any help would be greatly appreciated! Update: The very thorough and detailed answer by @JAlex below works perfectly, for both .NET Framework and .NET Core. My ongoing issues are due to user account policies at my workplace that prevent running *.dll files (apparently). Trying the solution on a normal, un-restricted system worked perfectly without issue.  |

It should run with no error. --- title: "testChi" author: "g" date: "10/15/2021" output: pdf_document: default word_document: default html_document: default --- ```{r setup, include=FALSE, error=FALSE, warning=FALSE} library(magrittr) library(dplyr) library(readr) library(pander) # cols <- svy_final %>% select(matches("Q44_[[:digit:]]")) %>% names(.) cols <- mtcars %>% select(matches("mpg|cyl|disp")) %>% names(.) create_plots <- function(dat,title_name) { # school <- enquo() for (i in cols) { plt <- sjPlot::tab_xtab( var.row = dat$gear, var.col = dat[[i]], show.row.prc = TRUE, var.labels = c("gear size", i), title = title_name ) # return(out) print(plt) } } ``` ```{r loop_print, results = 'asis',error=FALSE, warning=FALSE, message=FALSE} create_plots(mtcars, 'gear and stuff') %>% pander() ```

| pass variable from one page to another in angular 10 Posted: 22 Oct 2021 07:56 AM PDT Hi I am trying to pass a variable from one component to another, I tried the following: @Output() public userFlow = new EventEmitter<boolean>(); this.userFlow.emit(this.userFlowThrough);
Now in my other page I want to receive it but just in the ts file and not the html as it will be used for internal logic. I tried this but it did not work: @Input() userFlow: boolean;

| iOS Bluetooth Low Energy Scan in Background (swift3) Posted: 22 Oct 2021 07:57 AM PDT I'm actually working on a Bluetooth Low Energy app on iOS, written in Swift3.
My app is working well when is in foreground (scan, connect, exchange data..) with CoreBluetooth whereas, I want it to work in background (the first step is to scan peripheral in background). I read about the subject so I already added the Background modes for the BLE (I added all the background modes so the issue is not there). 
So, in my code, when I enter in the applicationDidEnterBackground method, I call the initCBCentralManager method. This is working well because it then go in the centralManagerDidUpdateState and in the "Powered On" state. My scan function is called so that's not the problem. But, after the scan method is called, nothing happens, I never get didDiscover peripheral called. When I use the functions in foreground (by calling my functions in applicationWillEnterForeground instead of applicationDidEnterBackground), it works, but not when it's in background. I read that I need to discover a particular service so it's what I do (my service is 6E400001-B5A3-F393-E0A9-E50E24DCCA9E and also that CBCentralManagerScanOptionAllowDuplicatesKey option will be ignored, but if I change it to false, nothing more happens. So, how am I supposed to scan Bluetooth Low Energy peripheral when I enter in background ? Here is my code : import CoreBluetooth @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate, CBPeripheralDelegate, CBCentralManagerDelegate { var _manager : CBCentralManager? func applicationDidEnterBackground(_ application: UIApplication) { initCBCentralManager() } func initCBCentralManager() { var dic : [String : Any] = Dictionary() dic[CBCentralManagerOptionShowPowerAlertKey] = false _manager = CBCentralManager(delegate: self, queue: nil) } public func centralManagerDidUpdateState(_ central: CBCentralManager) { switch central.state { case .poweredOff: print("State : Powered Off") case .poweredOn: print("State : Powered On") scan() case .resetting: print("State : Resetting") case .unauthorized: print("State : Unauthorized") case .unknown: print("State : Unknown") case .unsupported: print("State : Unsupported") } } func scan() { print("SCAN") let service = "6E400001-B5A3-F393-E0A9-E50E24DCCA9E" var service_cbbuid:[CBUUID] = [CBUUID(string: service)] _manager?.scanForPeripherals(withServices: service_cbbuid, options: [CBCentralManagerScanOptionAllowDuplicatesKey:true]) } func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) { print("BACKGROUND_SCAN -> \(peripheral.name.unsafelyUnwrapped) \(RSSI)dBm") }

| Restful API becomes 404 when using the CXF at the same time Posted: 22 Oct 2021 07:56 AM PDT I have a project starts up with Spring Boot. It has some restful API via Spring Integration inbound gateway. Afterward, some webservice endpoint added to the project with CXF. When I setup the CXFServlet mapping, all the restful API became 404. Only I suspend the CXF config the restful API available again. May I know if there is anything block the restful API or the spring integration inbound gateway during using CXF?

| viewing core when compiling with cabal Posted: 22 Oct 2021 07:56 AM PDT When building my application, I would like cabal to automatically output the intermediate core to a file. I can add the -ddump-simpl flag to the cabal file's ghc-options field, but this prints everything to stdout. Is there a way I can get cabal to redirect all of this to a file?  |

| django & the "TemplateDoesNotExist" error Posted: 22 Oct 2021 07:56 AM PDT Ive got an as it seems common beginners problem. im working on my first django project and when I set up my view I get an "TemplateDoesNotExist" error. Ive spend lots of hours on this now - and I know theres lots of topics on it but nothing helped me till now. I hope I can supply all the information needed so an advanced django user can probably directly see what Im doing wrong. im using the developement server. and windows 7 & sqlite3. this is the error I get: TemplateDoesNotExist at /skates/ allsk8s.html Request Method: GET Request URL: http://127.0.0.1:8000/skates/ Django Version: 1.4.3 Exception Type: TemplateDoesNotExist
in settings.py I set up the TEMPLATE_DIRS like this: TEMPLATE_DIRS = ( r'H:/netz2/skateprojekt/templates/', )
the template loaders looks like this: TEMPLATE_LOADERS = ( 'django.template.loaders.filesystem.Loader', 'django.template.loaders.app_directories.Loader', # 'django.template.loaders.eggs.Loader', )
this is my view: from django.shortcuts import render_to_response from django.template import RequestContext from sk8.models import Sk8 def AllSk8s(request): skates = Sk8.objects.all().order_by('name') context = {'skates':skates} return render_to_response('allsk8s.html', context, context_instance=RequestContext(request))
it should link to allsk8s.html - and it looks like it does but the file can not be found although it is definitely in the right folder. but as you can see: Template-loader postmortem Django tried loading these templates, in this order: Using loader django.template.loaders.filesystem.Loader: H:\netz2\skateprojekt\templates\allsk8s.html (File does not exist)
this is a part of my urls.py urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), (r'^skates/$', 'sk8.views.AllSk8s'), )
and this is the system path: H:\netz2\skateproject\templates
and in the templates folder is a file called allsk8s.html so as far as I understood it - this should work. I really hope somebody can help me cause this is the second time I ran into a problem like this and I can not figure out the problem. thanks in advance danielll
edit: I tried to add this to my settings.py: import os DIRNAME = os.path.abspath(os.path.dirname(__file__))
and changed my TEMPLATE_DIRS to: TEMPLATE_DIRS = ( os.path.join(DIRNAME, r'H:/netz2/skateprojekt/templates/'), )
cause I read it would help - but it still returned the same error - so I changed it back again. ;(
edit: also, Ive checked, when I enter a wront url, it throws this error: Using the URLconf defined in skateproject.urls, Django tried these URL patterns, in this order: ^admin/ ^skates/$
so the skates url should be there - but cant be "resolved" - i dont get it :(
edit: I found out something new today, the Template-loader postmortem says it also checks these directories: Using loader django.template.loaders.app_directories.Loader: C:\Python27\lib\site-packages\django\contrib\auth\templates\allsk8s.html (File does not exist) C:\Python27\lib\site-packages\django\contrib\admin\templates\allsk8s.html (File does not exist)
so I moved my template files there and received a new error - got this fixed by converting my html files from ansi to utf8 and tada - it worked. unfortunately I can not let the template files in this folder cause its not part of the project. when i moved the files back to the original location I was back at the old error :(  |
