generics - protected static string accessability issue in C# -


i have abstract base class templated. 

public abstract class base<t> t : new() {      protected static string magic; }

i have 2 classes derive base, different values of t.

public class derived1:base<other1> {}  public class derived2:base<other2> {}

two odd things seem happening. first of all, derived2.magic available within member function of derived1; not expect that. additionally, derived2 has static constructor sets magic; odd part being derived2's static constructor not called when derived1 accesses derived2.magic (which shouldn't allowed).

two questions:

  • why can derived1 access protected static member of derived2?

  • i thought static constructors run before static members accessed, why when access derived2.magic, not seeing it's static constructor called?

both of these seem serious bugs.

just adding note if magic on other hand static protected function, problem not exist, makes whole thing more unclear.

why can derived1 access protected static member of derived2?

magic in common base class, not in derived2. subclass of base<t> see variable of same name, though different variables if t different each derived class.

i thought static constructors run before static members accessed, why when access derived2.magic, not seeing it's static constructor called?

there no declaration derived2.magic, there declaration base<t>.magic. derived1 accessing protected field declared in own base class.

you starting assumption magic declared in derived2. if change code that's case, expectations hold.

authentication - Mongodb revoke acccess to connect test database -

i have ec2 instance mongodb 3.2.0 installed. have user admin access. can connect user , perform operation remotely. 1 can connect database test remote if knows ip mongo 11.11.11.11. although not able make operations, want restrict access user credentials can connect server. first need create users , grant roles users, example: use admin db.createuser( { user: "myuseradmin", pwd: "abc123", roles: [ { role: "useradminanydatabase", db: "admin" } ] } ) then need start server --auth parameter mongod --auth more information here

r - Update two sets of radiobuttons reactively - shiny -

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
