  • How can I port a MonoGame Windows Phone 8 game to iOS?

    - by Homer_Simpson
    I downloaded the trial version of Xamarin Studio and installed it on my iMac. In addition, I installed Xcode on my iMac so that I can use the iPhone emulators in Xamarin Studio. But I don't know how to use my MonoGame Windows Phone 8 source files in a Xamarin iPhone project. How can I use my Windows Phone code in an iPhone project? Can I import all my existing classes(for example Game1.cs) in an iPhone project without changing something? How can I port a MonoGame Windows Phone 8 game to iOS?

  • From Sinatra Base object. Get port of application including the base object

    - by Poul
    I have a Sinatra::Base object that I would like to include in all of my web apps. In that base class I have the configure method which is called on start-up. I would like that configure code to 'register' that service with a centralized database. The information that needs to be sent when registering is the information on how to contact this web-service... things like host and port. I then plan on having a monitoring service that will spin over all registered services and occasionally ping them to make sure they are still up and running. In the configure method I am having trouble getting the port information. The 'self.settings.port' variable doesn't seem to work in this method. a) any ideas on how to get the port? I have the host. b) is there a sinatra plug-in that already does something like this so I don't have to write it myself? :-) //in my Sinatra::Base code. lets call it register_me.rb RegisterMe < Sinatra::Base configure do //save host and port information to database end get '/check_status' //return status end //in my web service code require register_me //at this point, sinatra will initialize the RegisterMe object and call configure post ('/blah') //example of a method for this particular web service end

  • How do I figure out the minimum number of swaps to sort a list in-place?

    - by sova
    In-place sorting is essentially swapping elements without using extra storage, correct? How can I find the minimum number of swaps required for a list? A C D Q R Z E // input | | | > > > <<< // movement A C D E Q R Z // output Swapping: A C D Q R Z E swap Q with E, ACDERZQ swap R with Q, ACDEQZR swap R with Z, ACDEQRZ. done. 3 swaps. Shifting items left or right is essentially swapping, but I want the optimal number for plucking an item out of line and switching its place with another.

  • What Are Some Tips For Writing A Large Number of Unit Tests?

    - by joshin4colours
    I've recently been tasked with testing some COM objects of the desktop app I work on. What this means in practice is writing a large number (100) unit tests to test different but related methods and objects. While the unit tests themselves are fairly straight forward (usually one or two Assert()-type checks per test), I'm struggling to figure out the best way to write these tests in a coherent, organized manner. What I have found is that copy and Paste coding should be avoided. It creates more problems than it's worth, and it's even worse than copy-and-paste code in production code because test code has to be more frequently updated and modified. I'm leaning toward trying an OO-approach using but again, the sheer number makes even this approach daunting from an organizational standpoint due to concern with maintenance. It also doesn't help that the tests are currently written in C++, which adds some complexity with memory management issues. Any thoughts or suggestions?

  • True / false evaluation doesn't work as expected in Scheme

    - by ron
    I'm trying to compare two booleans : (if (equal? #f (string->number "123b")) "not a number" "indeed a number") When I run this in the command line of DrRacket I get "not a number" , however , when I put that piece of code in my larger code , the function doesn't return that string ("not a number") , here's the code : (define (testing x y z) (define badInput "ERROR") (if (equal? #f (string->number "123b")) "not a number" "indeed a number") (display x)) And from command line : (testing "123" 1 2) displays : 123 Why ? Furthermore , how can I return a value , whenever I choose ? Here is my "real" problem : I want to do some input check to the input of the user , but the thing is , that I want to return the error message if I need , before the code is executed , because if won't - then I would run the algorithm of my code for some incorrect input : (define (convert originalNumber s_oldBase s_newBase) (define badInput "ERROR") ; Input check - if one of the inputs is not a number then return ERROR (if (equal? #f (string->number originalNumber)) badInput) (if (equal? #f (string->number s_oldBase)) badInput) (if (equal? #f (string->number s_newBase)) badInput) (define oldBase (string->number s_oldBase)) (define newBase (string->number s_newBase)) (define outDecimal (convertIntoDecimal originalNumber oldBase)) (define result "") ; holds the new number (define remainder 0) ; remainder for each iteration (define whole 0) ; the whole number after dividing (define temp 0) (do() ((= outDecimal 0)) ; stop when the decimal value reaches 0 (set! whole (quotient outDecimal newBase)) ; calc the whole number (set! temp (* whole newBase)) (set! remainder (- outDecimal temp)) ; calc the remainder (set! result (appending result remainder)) ; append the result (set! outDecimal (+ whole 0)) ; set outDecimal = whole ) ; end of do (if (> 1 0) (string->number (list->string(reverse (string->list result))))) ) ;end of method This code won't work since it uses another method that I didn't attach to the post (but it's irrelevant to the problem . Please take a look at those three IF-s ... I want to return "ERROR" if the user put some incorrect value , for example (convert "23asb4" "b5" "9") Thanks

    - by 2600th
    I have just made my first game for iOS and submitted it to app store. I was thinking of porting my game to Android also. I would like to know things one need to do/remember to port game made for iOS in Unity to Android. How to handle different screen resolutions and pixel densities, optimizations required, etc. Any other suggestions and important things you think I should know? EDIT: Also, should I handle builds according to device resolutions or by pixel density?

  • how to find missing rows in oracle

    - by user203212
    Hi, I have a table called 2 tables create table ORDERS ( ORDER_NO NUMBER(38,0) not null, ORDER_DATE DATE not null, SHIP_DATE DATE null, SHIPPING_METHOD VARCHAR2(12) null, TAX_STATUS CHAR(1) null, SUBTOTAL NUMBER null, TAX_AMT NUMBER null, SHIPPING_CHARGE NUMBER null, TOTAL_AMT NUMBER null, CUSTOMER_NO NUMBER(38,0) null, EMPLOYEE_NO NUMBER(38,0) null, BRANCH_NO NUMBER(38,0) null, constraint ORDERS_ORDERNO_PK primary key (ORDER_NO) ); and create table PAYMENTS ( PAYMENT_NO NUMBER(38,0) NOT NULL, CUSTOMER_NO NUMBER(38,0) null, ORDER_NO NUMBER(38,0) null, AMT_PAID NUMBER NULL, PAY_METHOD VARCHAR(10) NULL, DATE_PAID DATE NULL, LATE_DAYS NUMBER NULL, LATE_FEES NUMBER NULL, constraint PAYMENTS_PAYMENTNO_PK primary key (PAYMENT_NO) ); I am trying to find how many late orders each customer have. the column late_days in PAYMENTS table has how many days the customer is late for making payments for any particular order. so I am making this query SELECT C.CUSTOMER_NO, C.lname, C.fname, sysdate, COUNT(P.ORDER_NO) as number_LATE_ORDERS FROM CUSTOMER C, orders o, PAYMENTS P WHERE C.CUSTOMER_NO = o.CUSTOMER_NO AND P.order_no = o.order_no AND P.LATE_DAYS>0 group by C.CUSTOMER_NO, C.lname, C.fname That means, I am counting the orders those have any late payments and late_days0. But this is giving me only the customers who have any orders with late_days0, but the customers who does not have any late orders are not showing up. so if one customer has 5 orders with late payments then it is showing 5 for that customer, but if a customer have 0 late orders,that customer is not selected in this query. Is there any way to select all the customers , and if he has any late orders, it will show the number and also if he does not have any late orders, it will show 0.

  • Why is it an issue that it takes 2 digits to represent the number 10 in decimal?

    - by Crizly
    So we use hexadecimal which has the advantage of going up to 15 in single digits A-F, but why is it an issue that it takes 2 digits to represent the number 10 in decimal? I was reading up about hexadecimal and I came across these 2 lines: Base 16 suggests the digits 0 to 15, but the problem we face is that it requires 2 digits to represent 10 to 15. Hexadecimal solves this problem by using the letters A to F. My question is, why do we care how many digits it takes to represent 15? What is the importance of this number, and how does denoting it with a single character have any value?

  • Office bientôt sur iPad ? Microsoft travaillerait sur le port de sa suite bureautique sur iOS

    Office bientôt sur iPad ? Microsoft travaillerait sur le port de sa suite bureautique sur iOS Microsoft travaillerait activement sur l'adaptation de sa suite bureautique Office pour l'iPad. Selon le quotidien The Daily et des sources anonymes, l'éditeur pourrait dévoiler une application Office pour iPad avant le lancement de la prochaine version de la suite bureautique pour Mac, en début de l'année prochaine. La solution viendra concurrencer les applications de bureautique existantes sur la plateforme, plus particulièrement les outils d'Apple iWork. The Daily estime d'ailleurs que le prix serait sensiblement équivalent à celui de iWork, soit un tarif de 10 dollars. ...

  • Common and maximum number of virtual machines per server?

    - by Rabarberski
    For a project I am trying to get real-life estimates for the number of virtual machines per server, both typically and maximally. Of course, the maximum number of VMs would be depending on the type of applications (disk intensive, network intensive, ...), and server hardware (like number of cores, memory, ...), but still it would be useful to know if a typical maximum is about 10, 20 or 30 VMs per server. Can anybody give practical numbers?
