"Connecting within ArcGIS application with resource",
"I have following dillema:\nUsing ArcGIS Enterprise 10.8, I have added a new item – Application – to a users content.\nThis generates an Application item, with an App ID and APP Secret, along with App type and redirect URIs defined.\nThese can be used to generate an access token via the OAUTH2 token endpoint:\nhttps:///sharing/rest/oauth2/token\nusing the parameters :\nclient_id=APPID&\nclient_secret=APPSECRET&\ngrant_type=client_credentials\nESRI States in their documentation:\n“Successful authentication directly returns a JSON response containing the access token that allows the application to work with resources that are accessible to the application (that is, have been shared with the application). Use of the client_secret as previously described is mandatory.”\nQuestion is: how do we share resources with the application?\nThe overall goal is to grant an external application (unknown user) access to portal ressources (ie.a layer item) via OAUTH2 app login.\nDo you have any suggestions?"

"EWS SOAP Open Folder given uint8_t ID",
"Using the EWS API, I am given a const uint8_t *longTermID and its uint32_t idSize to use to open a folder. In our old MAPI code, we would call GetIdFromLongTermId using some types defined in the MAPI headers. I can't seem to find anything equivalent for using a uint8_t ID to open a folder for EWS. I tried\n\nConvertId Operation with EntryId as the AlternateId Format to a DestinationFormat of EwsId but that result fails.\n\nThis is the first time I've worked on exchange server stuff, and all of this was previously done by a developer who no longer works here. \n\nI've tried to change it to a string via string id(longTermID, longTermID+idSize) but that just produces a blank string. \n\nWould I want something like GetItem operation?"

Is there a better way to do this? I mean, I don't want VecMyObjs to change VecMyObj outside of the class, of course. How can I achieve that without a compiler warning?\n\nEDIT:\nOkay. Thank you everybody. It's now like this:\n\nconst vector<MyObject *const> ACI_CALL MyClass::GetVecMyObjs()\n{\n const vector<MyObject *const> VecMyObjs;\n VecMyObjs.assign( _VecMyObjs.begin(), _VecMyObjs.end());\n return VecMyObjs;\n}\n\n\nBut, I can't get around the assign-function, right? E.g. casting the \"original\" doesn't work, if I want \"everything\" to be constant."

"When reading an external PDF with an Android App it always shows the same version, even after updating the PDF",
"Please don´t be too harsh to me concerning any mistakes with this question since thats my first one here.\n\nSo basically what i want to do is reading/showing a PDF document in my Android App after pressing a button. The PDF is located on a Raspberry Pi 3 and i found a code example on this thread how to read it.\nBefore accessing it however, i call a python script on the Raspi which is (re)creating the PDF based on a database. \n\nSo the user presses the button in the App and sees a PDF which presents the current state of a database table.\n\nNow i got the following code in my Activity to call the script and read the PDF:\n\n new AsyncTask<Integer, Void, Void>(){\n @Override\n protected Void doInBackground(Integer... params) {\n try {\n executeRemoteCommand(\"user\",\"pw\",\"ip\", port, \"command to execute the python script\");\n } catch (Exception e) {\n e.printStackTrace();\n }\n return null;\n }\n }.execute(1);\n //waiting for the PDF to be created\n handler.postDelayed(new Runnable() {\n @Override\n public void run() {\n String url = \"http://IP/path/file.pdf\";\n Intent i = new Intent(Intent.ACTION_VIEW);\n i.setData(Uri.parse(url));\n startActivity(i);\n }\n }, 5000);\n\n\nWith this code connecting to the Raspberry, executing the python script, thus updating the database and reading the PDF file works just fine.\n\nBut i have the following problem:\n\nWhen i close the PDF view in my App, add something to the database and press the executing button again the PDF file itself is being updated (i checked that on the Raspberry) but then the App still shows the old version of it. Even when i restart the App and execute this again it still shows the first version of the PDF... \n\nDoes anyone have an idea why and how to fix this?\n\nIs there any kind of cache which stores the PDF and just shows the same every time i read from the Raspberry?"

"C#: Sane alternative to optional parameter in property?",
"Given: a class with properties like SomeNumber that, internally can be null (i.e. int?), but externally, you typically don't want to handle that special case, and pretend they start out as zero. So far, we're always returning a non-nullable version, i.e. int. I'd like to add an option to have a nullable version.\n\nThe easiest variant: Two properties. Works great, but unfortunately clutters the class with lots of largely redundant options. External code:\n\nreturn myObject.SomeNumber; // Not nullable.\nreturn myObject.SomeNumber_Nullable; // Nullable.\n\n\nThe internally dirty, but externally nice variant: A property with an optional parameter. I haven't yet found out how to do this in C#; .NET Reflector seems to be omitting incorrect code. In VB.NET, it looks like so:\n\nPrivate _SomeNumber As Nullable(Of Integer)\nPublic Property SomeNumber(Optional ByVal AllowNull As Boolean = False) As Nullable(Of Integer)\n Get\n If Not AllowNull AndAlso _SomeNumber Is Nothing\n Return 0\n End If\n\n Return _SomeNumber\n End Get\n Set(ByVal value As Boolean)\n _SomeNumber = value\n End Set\nEnd Property\n\n\nExternal code:\n\nreturn myObject.SomeNumber; // Not nullable.\nreturn myObject.SomeNumber(true); // Nullable.\n\n\nAmong the disadvantages:\n* C# implementation is so ugly .NET Reflector doesn't even seem to know how to do it,\n* I find the general notion of parameterized properties questionable,\n* In the non-nullable example, the return type doesn't match the actual behavior of the property — the compiler now thinks it can be null, but it really can't.\n\nAny other ideas?"

"Referencing string resources in VS2015 Shared Project from multiple WPF projects",
"I have a couple standard WPF projects (not UWP) that are both referencing a shared project using the new Visual Studio 2015 Shared Project type. This looks like it works great for sharing code, but I'd also like to share strings and other resources that would normally be found in a resource.resx file. Focusing on strings, I have created a resource.resw file in the shared project and populated with my values. But I'm stuck on how to reference those values from either of my WPF projects.\n\nI see that, by default, the .resw file has a build action of PRIResource. I'm not sure what that type of resource is exactly, nor have I been able to find anything useful to explain it. Either way, I haven't been able to reference my strings with that build action. I have also tried changing build action to Embedded Resource, along with setting a unique Custom Tool Namespace value, but that doesn't seem to give me access either.\n\nI'm used to accessing string resources that live in .resx files by using MyNamespace.Properties.Resources.MyStringKey, but no such path seems to resolve when trying to reference the .resw file. I've also seen references to using the ResourceLoader class to access those strings, but that seems to be specific to UWP.\n\nHow do I access .resw strings that live in a Visual Studio 2015 Shared Project from the projects that reference it?"

"Can/Should custom $resource action methods be tested?",

So I've used fresh tyvar names.\nThe GADT gives Nil :: Vec a Zero, so I give that as its pattern signature (with a fresh aa). But it seems GHC can't unify the n from append's signature with the Zero. If I change that equation to either of these, all is happy:\nappend (Nil :: Vec aa nn) (w :: Vec aa mm) = w :: Vec aa (nn + mm)\n\nappend (Nil :: Vec aa nn) (w :: Vec aa mm) = w :: Vec aa (mm)\n\nTo validate those, GHC must be figuring out that Nil :: Vec a Zero and that Zero + m = m from the type family equation for +. So why is it grumpy about the pattern signature with Zero?\n(I was originally trying to give the equations for append purely with PatternSignatures, to see if GHC could infer the signature. That didn't get off the ground.)"

So if I add a phishing site like thisisevil.com the api-call returns a warning. \n\nBut if someone uses an url shortener like tny.sh/abcefg which then redirects to thisisevil.com the safebrowsing-api does not show me there is a threat.\n\nIs there a way to tell the secure browsing api to follow redirects?"

"Turning an Integer into a Base 10/Decimal System format?",
"As part of my Cryptography Module's CW, I need to use the Extended Euclidean Algorithm to calculate the Greatest Common Denominator, GCD, of two BigIntegers. I've done this, it's easy and I know my code works.\n\nHowever, there's a further specification that:\n\n\n Compute the Extended Euclidian algorithm for the following inputs and provide (d, s, t) in decimal system format in a text file with one line per number.\n\n\nI'm assuming they're asking me to write a file with 3 lines, a line representing each of the outputs converted from an integer representation to a base 10 representation, ie:\n\n\n (1 x 100,000 (10^5)) + (2 x 10,000 (10^4)) + (6 x 1000 (10^3)) + (3 x 100 (10^2)) + (2 x 10 (10^1)) + (5 x 1) = 126,325\n\n\nIs my interpretation correct?
