"Android: How to detect Dual sd-card",
"Is there any way of identifying if there are two sd-cards in a device?? \n\nEdit: \n\nI have found that at the moment, there is no way of distinguishing between internal storage and true external SD card. In some devices like Samsung Galaxy Tab (7 inches), the system takes the internal storage (usually 16gb) to be as an external storage. Unfortunately there is no way to distinguish between internal storage and secondar/external/sd-card storage. If someone thinks it is possible (for honeycomb and previous versions), write here and I'll prove it."

"How to create a generic tool to list and edit the properties of any object? (C#)",
"I am creating an editor for my game as a windows forms project to enter all of the data into the game.\nThe game includes many different class and struct definitions (eg: Items, Entities, coordinates, Terrains, etc.) And each instance of those things needs to have its properties set in the editor.\n\nCreating a custom tool for every single type of object defined in my code base is too involved. It would take me longer to set up all of those tools than it does to program the game its self. I need to create generic and re-usable tools. So far I have learned to use the \"Property Grid\" which automatically lets you set any data-type in a given object. (assuming that you give it a \"get; set;\" access modifier.) But what about reference types and data structures?\n\nI want to make a generic tool to inspect and edit the properties of any object:\n\n\nCan I make a tool that will display an \"add\" button for any null\nreference type variable in the inspected object?\nAnd a \"Edit\" and \"delete\" button for any reference type variable\nthat is not null in the inspected object?\nCan the \"add\" button prompt me to choose from a list any\nnon-abstract type that derives from the type of the reference?\nCan the tool also display a list of \"edit\" or \"delete\" nodes and a\n'add' button for any 'List' in the inspected object?\nAnd to data type variable need to have a \"get; set;\" access modifier\non them for them to turn up in the property grid? Why can't it\ndetect any public variable in the inspected object?\nHow do you detect all of the properties of an object? How does the\nproperty inspector do it?"

"Is this a new way to implement Decorator or Multiple inheritance in Java?",
"I'm wondering if I found a an alternative way to implement the Decorator Design Pattern in Java? Is this possibly a new way to do something similar to multiple inheritance in Java? Would there be a better way to implement the problem below?\n\nI'm providing a minimal example, for the following problem (image a simple Game Engine):\n\n\nActor: Is a basic actor, which has a position (on the screen) and a flag for visibility\nSome Actors are Damagable, which means they are extended by health-points, methods to apply damage and to destroy them (make the base actor invisible) if necessary.\nSome Actors are Physical, which means they can have forces like gravity applied, which effectively changes the position of the base Actor.\nSome Actors are Damagable and Physical, so they should do a kind of multiple inheritance or apply 2 Decorators (using the Decorator pattern). The EnemyActor is an example of this, which of course has additionally its own methods.\n\n\nHere is my implementation (minimalised):\n\npublic class Actor {\n int posX;\n int posY;\n boolean visible = true;\n}\n\npublic class DamagableActorDecoration {\n float health = 10;\n private final Actor base;\n\n public DamagableActorDecoration(Actor base) {\n this.base = base;\n }\n\n void applyDamage (float dmg) {\n health -= dmg;\n if (health<=0)\n base.visible = false;\n }\n\n boolean isDestroyed () {\n return health<=0;\n }\n}\n\npublic class PhysicalActorDecoration {\n private final Actor base;\n\n public PhysicalActorDecoration(Actor base) {\n this.base = base;\n }\n\n public void applyGravity () {\n base.posY--;\n }\n}\n\npublic interface Damagable {\n DamagableActorDecoration d();\n}\n\npublic interface Physical {\n PhysicalActorDecoration p();\n}\n\npublic class EnemyActor extends Actor implements Damagable, Physical{\n @Override\n public DamagableActorDecoration d() {\n return new DamagableActorDecoration(this);\n }\n @Override\n public PhysicalActorDecoration p() {\n return new PhysicalActorDecoration(this);\n }\n\n public void showExplodingParticleSystem (){}\n}\n\n\nNow I can create an Enemy that extends Actor, has its own methods and is also Damagable and Physical. For example by using it like this:\n\npublic class Runner {\n public static void main(String[] args) {\n EnemyActor enemy1 = new EnemyActor();\n\n // basic actor behavior : appear\n enemy1.visible=true;\n\n // basic actor behavior : move forward\n enemy1.posX++;\n\n // damagable actor behavior : receive damage\n enemy1.d().applyDamage(0.7f);\n\n // physical actor behavior : fall down\n enemy1.p().applyGravity();\n\n // damagable actor behavior : be destroyed\n if (enemy1.d().isDestroyed())\n {\n // enemy actor behavior : explode into pieces\n enemy1.showExplodingParticleSystem();\n }\n }\n}"

"Rails 5 server hangs when receives multiple requests at once",

There is no error, it just hangs on the POST requests. When I try to kill the server with CTRL + C, nothing happens.

I am sending around 5 requests concurrently from frontend, so I believe this amount of requests is causing it, but I don't know for sure.\n\nHas anyone else experienced this or have an idea of what needs to be done here? I can usually get all the requests coming back to the frontend successfully around 3-4 times, then the server just freezes.\n\nIt especially occurs after I change any one line of code in any file in the project while the server is running."

"In Voldemort, why does the hash ring only extend to 2^31-1?",
"On the project voldemort design page:\n\nhttp://project-voldemort.com/design.php\n\nIt is stated that the hash ring covers the interval [0, 2^31-1].\n\nNow, the interval [0, 2^31-1] represents 2^31 total numbers, and the largest number 2^31-1 is just 31 bits all set to 1. (To convince yourself of this, consider 2^3-1. 2^3=8 and is 0x1000. 2^3-1=7 and is 0x111).\n\nThus, if a normal 32-bit address word is used to store the value, you have 1 bit free.\n\nThus, why is 2^31-1 the upper limit? Is that extra bit used for some kind of system bookkeeping? \n\n(e.g. 1 extra bit would provide room for safely adding two valid hash addresses without overflow).\n\nAnd finally, is this choice specific to voldemort, or is it seen in other consistent hashing schemes?"

But sometime ago I've seen an implementation with web api v1 using some kind of custom lookup mechanisms to handle this.

"Value of auth.provider for Phone Authentication & Facebook in Firebase Database",
"As per the documentation, the values for all providers are given except for Phone Authentication. I want to verify in my database if a user has authenticated with both Phone Authentication and Facebook. Writing a rule as auth.provider === 'facebook' works, but auth.provider === 'phone' doesn't. Logically, if the first one worked then the second one shouldn't work, but what if I say that I always sign in with Phone credentials and linked Facebook credentials with the Phone credentials the first time? In a nutshell:\n\n\nIs there a value of auth.provider for Phone Authentication? If yes, what is it?\nIs there a way to check if the user has both Facebook and Phone as providers in my database? I don't care if the user signs in with either of them. The only thing I want is that the user should have linked his Facebook credentials to the Phone.\nAssuming that auth.provider only gives the value of the provider used to sign in, why is auth.provider === 'facebook' working when I never sign in a user with Facebook and only link it with Phone credentials?\n\n\nUpdate:\n\n\nWith some trial and error, it seems that if Phone authentication is the only method used, then auth.provider is actually anonymous, not phone.\nAlso, based on bojeil's answer, auth.token.firebase.identities[\"phone\"] !=null turns out to be true. Point to be noted is that this is not documented in the documentation. Quoting from the documentation:\n\n\n\n firebase.identities: Dictionary of all the identities that are associated with this user's account. The keys of the dictionary can be any of the following: email, google.com, facebook.com, github.com, twitter.com.\n\n\nNo mention of phone here either. The last day the page was updated was May 17, 2017. One can only imagine the level of shoddiness in the documentation considering the Firebase SDK for Javascript (v4.0.0), which includes support for Phone authentication, was released on that very day (see release notes)."

"Strange spacing for CSS table using fractional heights",
"Edit: Sorry folks, looks like this was dumb JS bug I missed. It was inserting multiple empty rows in between each legitimate row. I'm not sure why they only start to show up near the bottom but it was because for every 1 real row there were 3 duplicate empty rows in between.\n\n\n\nEvery TD in the above table has the following classes/styles:\n\n.cell\n{\n background-color: lightgray;\n opacity: 1.0;\n vertical-align: middle;\n text-align: center;\n background-color: gray;\n cursor: pointer;\n}\n\n.hour\n{\n width: 100%;\n height: 8.33%\n}\n\n\nI imagine the 8.33% height is to blame but I have 12 rows and I want each of them to be 1/12th the height of the table. Is there a better way to do this that doesn't create weird gaps other than specifying a static number of pixels?"

"C++0x lambda wrappers vs. bind for passing member functions",
"This is basically a question about the readability, style, performance of 2 different approaches to creating/passing a functor that points to a member method from within a class constructor/method.\n\nApproach 1:\n\nusing namespace std::placeholders;\nstd::bind( &MyClass::some_method, this, _1, _2, _3 )\n\n\nApproach 2:\n\n[ this ](const arg1& a, arg2 b, arg3& c) -> blah { some_method( a, b, c ); }\n\n\nI was wondering if using the lambda is just gratuitous in this situation, in some respects it is easier to see what is going on, but then you have to explicitly provide the arg types. Also i prefer not to have \"using namespace whatever;\" but then it makes the bind expression needlessly verbose (eg. _1 becomes std::placeholders::_1), and lambda avoids this issue.\n\nFinally i should note that for the purposes of this question, some_method is a big function that does lots of things, and would be a pain to directly copy into a lambda body.\n\nIf this question seems too vague, then we can focus on answers to the performance differences, if any.\n\nEDIT: A non-trivial use case.\n\nMyClass::MyClass()\n: some_member_( CALLBACK_FUNCTOR )\n{}\n\n\nAs you can see, the CALLBACK_FUNCTOR used in an initializer list (defined with approach 1 or 2) makes it difficult to scope a using declaration (afaik), and obviously we wouldnt bother wrapping a member method that we intended to call straight away."

"Android WifiP2pManager discoverServices timeout",
"I've been working with the Android WifiP2pManager to discover specific services on other devices. I'm wondering if there is a known timeout period for the function\n\npublic void discoverServices (WifiP2pManager.Channel c, WifiP2pManager.ActionListener listener)\n\n\nI can't find any resources on it in the Android API. I'm aware that I can set a listener for a successful discovery, but I don't know how to tell if no discovery has been made.\n\nAdditionally, is there any way to stop discovery without entirely stopping the wifi manager's functionality?\n\nThanks in advance for any help!"

"WPF DataGrid with variable row heights",
"I am programmatically creating a DataGrid and need the row heights to be variable so that rows with multiple lines of text have a great height to accomodate the additional lines.\n\nI tried setting the RowHeight property in code, but this requires a fixed value. If I leave RowHeight unset it just uses an arbitrary value that does not expand if the text doesn't fit.\n\nI would also like to have my DataGrid contents to be scaleable, so if the DataGrid is resized the actual cell resize as well, including the font inside the cells. I could use a Viewbox for this, but I've had issues with the Viewbox as it will not grow to fit the text, it shirks/expands the text to fit in it.\n\nPerhaps I need to walk through all of the rows and columns on a resize and set the height property manually."

"What is a message pump?",
"In this thread (posted about a year ago) there is a discussion of problems that can come with running Word in a non-interactive session. The (quite strong) advice given there is not to do so. In one post it is stated "The Office APIs all assume you are running Office in an interactive session on a desktop, with a monitor, keyboard and mouse and, most importantly, a message pump." I'm not sure what that is. (I've been programming in C# for only about a year; my other programming experience has primarily been with ColdFusion.)\nUpdate:\nMy program runs through a large number of RTF files to extract two pieces of information used to construct a medical report number. Rather than try and figure out how the formatting instructions in RTF work, I decided to just open them in Word and pull the text out from there (without actually starting the GUI). Occasionally, the program hiccuped in the middle of processing one file, and left a Word thread open attached to that document (I still have to figure out how to shut that one down). When I re-ran the program, of course I got a notification that there was a thread using that file, and did I want to open a read-only copy? When I said Yes, the Word GUI suddenly popped up from nowhere and started processing the files. I was wondering why that happened; but it looks like maybe once the dialog box popped up the message pump started pushing the main GUI to Windows as well?"

"How do you enable a GL function in Qt3D with QML",

I have created a QML effect that loads my shader programs similar to the PerVertex color effect QML that ships with Qt5.9.\n\nThe problem I am having is I am trying to write a fragment shader and utilize glBlendFunc(sfactor, dfactor). According to the OpenGL documentation, I need to set glEnable(GL_BLEND) and use glBlendFunc, but I don't know how to do that using QML.
