  • Create numbers within an array that add up to a set amount

    - by RussellDias
    I'm fairly new to PHP - programming in general. So basically what I need to accomplish is, create an array of x amount of numbers (created randomly) who's value add up to n: Lets say, I have to create 4 numbers that add up to 30. I just need the first random dataset. The 4 and 30 here are variables which will be set by the user. Essentially something like x = amount of numbers; n = sum of all x's combined; create x random numbers which all add up to n; $row = array(5, 7, 10, 8) // these add up to 30 Also, no duplicates are allowed. I need the values with an array. I have been messing around with it sometime, however, my knowledge is fairly limited. Any help will be greatly appreciated. Cheers

  • Scaling range of values with negative numbers

    - by Pradeep Kumar
    How can I scale a set of values to fit a new range if they include negative numbers? For example, I have a set of numbers (-10, -9, 1, 4, 10) which have to scaled to a range [0 1], such that -10 maps to 0, and 10 maps to 1. The regular method for an arbitrary number 'x' would be: (x - from_min) * (to_max - to_min) / (from_max - from_min) + to_min but this does not work for negative numbers. Any help is appreciated. Thanks!!

  • Extracting numbers from a url using javascript?

    - by stormist
    var exampleURL = '/example/url/345234/test/'; var numbersOnly = [?] The /url/ and /test portions of the path will always be the same. Note that I need the numbers between /url/ and /test. In the example URL above, the placeholder word example might be numbers too from time to time but in that case it shouldn't be matched. Only the numbers between /url/ and /test. Thanks!

  • determine complex type from a primitive type using reflection

    - by Nilotpal Das
    I am writing a tool where I need to reflect upon methods and if the parameters of the methods are complex type, then I need to certain type of actions such as instantiating them etc. Now I saw the IsPrimitive property in the Type variable. However, it shows string and decimal as complex types, which technically isn't incorrect. However what I really want is to be able to distinguish developer created class types from system defined data types. Is there any way that I can do this?

  • Split a complex GUI window into several files in Netbeans

    - by Hectoret
    After building the application GUI, I realised it was a little bit too complex and I could reuse some of the Swing components. The result is a complex class with many anidated JPanels. My question is: does Netbeans provide a way to split a JPanel and its children components into a different class? If I do it by hand, will the GUI designer still work? Thanks!

  • Asterisk - Trying to use call files to create a conference call between two dynamic numbers

    - by Hank
    I'm trying to setup an Asterisk system that will allow me to create a conference call between two dynamic numbers. It seems I can use 'call files' to make Asterisk initiate the call without needing an incoming call - http://www.voip-info.org/tiki-index.php?page=Asterisk+auto-dial+out This example seems to be what I'd need: Channel: SIP/mytrunk/12345678 MaxRetries: 2 RetryTime: 60 WaitTime: 30 Context: callme Extension: 800 Priority: 2 I can generate this file with some scripting language and then place it into the Asterisk Call File folder. The problem I'm having is: How do I call out to two numbers and join them in a conference call? The MeetMe plugin/extension seems to be what I need in terms of conference calling, I'm just unsure as to how I'd use the two together and join them. Also, is it possible to have multiple 2-person conference calls at the same time? Is setting this up as simple as setting aside X amount of 'channels' in the meetme.conf?

  • Using international phone numbers on iPhone [closed]

    - by Cawas
    Spin off question Is it possible to hack a SIM card to add a javacard application on it (to properly format international numbers)? If yes, how? Original Question In my previous phone carrier I could just dial +55 11 99883655 and it would just work. Now I moved to a new carrier and it doesn't work anymore! When I dial the same international number it keeps saying the number isn't formated correctly. How can I get my iPhone to understand international numbering back again? I've got over 100 contacts with numbers stored in this format already, and I want to keep them that way. edit: I originally asked this question here, moved it to apple stackexchange and now I'm bringing a new one (hopefuly).

  • Context is Hindi when printing line numbers in Word 2007

    - by Lessan Vaezi
    I'm trying to print a Word 2007 document with Line Numbering turned on, and in Word the document looks fine but when I print the document, the line numbers appear in Hindi script. See screenshots here: http://www.lessanvaezi.com/context-is-hindi-when-printing-line-numbers-in-word-2007/ I tried deleting my Normal template and allowing Word to create a new one, and testing using that, with no change. I also tried using different printers. The problem goes away if I choose Arabic instead of Context under Word Options - Advanced - Show Document Content / Numeral. However, I would like to keep this setting as Context. The question is, why is the default context of my document Hindi script? Is there a way to change this context?

  • Numbering equations based on chapter numbers in MS-Word

    - by Isaac
    I am seeking for a way to number each equation based on the chapter numbers. The number should be placed at the right side of the equation and the equation should be center-aligned. Something like this: (The bounding box around 2.3 is not necessary). I found this article that do this in a tricky way. Sadly it has some problems when I use multilevel numbering for Headings. To conclude, I am looking for a way to numbers equations that: The numbering is formatted as N-M that N is chapter number and M is equation number. equation is placed in center-aligned number is placed in the right side of equation There should be a way to cross-reference each numbered equation. Thanks!

  • Automation for filling in sets of numbers in each row

    - by Brad
    I need to populate the same number 10 times in a row, then the next number up on the next row. starting at 0, ending at 1000 for example: 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3 3 .... 1000 1000 1000 1000 1000 and to 1000 I need to print out these numbers to cut up and put each row of numbers in each envelope to be sold for a Chinese auction at a benefit. How do I do this dynamically without entering in all of the rows by hand?

  • How does Ocaml decide precedence for user-defined operators?

    - by forefinger
    I want nice operators for complex arithmetic to make my code more readable. Ocaml has a Complex module, so I just want to add operators that call those functions. The most intuitive way for me is to make a new complex operator from all of the usual operators by appending '&' to the operator symbol. Thus +& and *& will be complex addition and multiplication. I would also like ~& to be complex conjugation. If I'm going to use these operators, I want them to associate the same way that normal arithmetic associates. Based on the following sessions, they are automatically behaving the way I want, but I would like to understand why, so that I don't get horrible bugs when I introduce more operators. My current guess is that their precedence is done by lexically sorting the operator symbols according to an ordering that is consistent with normal arithmetic precedence. But I cannot confirm this. Session one: # open Complex;; # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} Session two: # open Complex;; # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} # let (~&) a = conj a;; val ( ~& ) : Complex.t -> Complex.t = <fun> # (one +& i) *& ~& (one +& i);; - : Complex.t = {re = 2.; im = 0.}

  • Html.DropDownListFor<> and complex object in ASP.NET MVC2

    - by dagda1
    Hi, I am looking at ASP.NET MVC2 and trying to post a complex object using the new EditorFor syntax. I have a FraudDto object that has a FraudCategory child object and I want to set this object from the values that are posted from the form. Posting a simple object is not a problem but I am struggling with how to handle complex objects with child objects. I have the following parent FraudDto object whcih I am binding to on the form: public class FraudDto { public FraudCategoryDto FraudCategory { get; set; } public List<FraudCategoryDto> FraudCategories { get; private set; } public IEnumerable<SelectListItem> FraudCategoryList { get { return FraudCategories.Select(t => new SelectListItem { Text = t.Name, Value = t.Id.ToString() }); } The child FraudCategoryDto object looks like this: public class FraudCategoryDto { public int Id { get; set; } public string Name { get; set; } } On the form, I have the following code where I want to bind the FraudCategoryDto to the dropdown. The view is of type ViewPage: <td class="tac"> <strong>Category:</strong> </td> <td> <%= Html.DropDownListFor(x => x.FraudCategory, Model.FraudTypeList)%> </td> I then have the following controller code: [HttpPost] public virtual ViewResult SaveOrUpdate(FraudDto fraudDto) { return View(fraudDto); } When the form is posted to the server, the FraudCategory property of the Fraud object is null. Are there any additional steps I need to hook up this complex object? Cheers Paul

  • XAML Binding to complex value objects

    - by Gus
    I have a complex value object class that has 1) a number or read-only properties; 2) a private constructor; and 3) a number of static singleton instance properties [so the properties of a ComplexValueObject never change and an individual value is instantiated once in the application's lifecycle]. public class ComplexValueClass { /* A number of read only properties */ private readonly string _propertyOne; public string PropertyOne { get { return _propertyOne; } } private readonly string _propertyTwo; public string PropertyTwo { get { return _propertyTwo; } } /* a private constructor */ private ComplexValueClass(string propertyOne, string propertyTwo) { _propertyOne = propertyOne; _propertyTwo = PropertyTwo; } /* a number of singleton instances */ private static ComplexValueClass _complexValueObjectOne; public static ComplexValueClass ComplexValueObjectOne { get { if (_complexValueObjectOne == null) { _complexValueObjectOne = new ComplexValueClass("string one", "string two"); } return _complexValueObjectOne; } } private static ComplexValueClass _complexValueObjectTwo; public static ComplexValueClass ComplexValueObjectTwo { get { if (_complexValueObjectTwo == null) { _complexValueObjectTwo = new ComplexValueClass("string three", "string four"); } return _complexValueObjectTwo; } } } I have a data context class that looks something like this: public class DataContextClass : INotifyPropertyChanged { private ComplexValueClass _complexValueClass; public ComplexValueClass ComplexValueObject { get { return _complexValueClass; } set { _complexValueClass = value; PropertyChanged(this, new PropertyChangedEventArgs("ComplexValueObject")); } } } I would like to write a XAML binding statement to a property on my complex value object that updates the UI whenever the entire complex value object changes. What is the best and/or most concise way of doing this? I have something like: <Object Value="{Binding ComplexValueObject.PropertyOne}" /> but the UI does not update when ComplexValueObject as a whole changes.

  • Complex Forms Generating Error

    - by user1648020
    I am working on an application that allows students to create a catalog of courses they are taking for a semester. I have created models for user; course; subject and category. Users can have many courses. Each course can have many subjects and categories. The tables for courses, subjects and categories include the following: Catalog: user_id; subject_id, category_id and course_id Courses: user_id; coursedetail_id Coursedetail: name; description Subject: name; description Category: name; description The idea is that an Admin can create a list of courses; subjects and categories and that the user can select the courses they want to add to their catalog. I have seperated courses and coursedetails because I envision that the coursedetails will grow overtime and the courses table will allow me to join the user_id and cousres details to rreport on if necessary. I attempted to follow Ryan's railscast on Complex Forms thinking that that I should use a complex form and has many relationship to get things working -- but I get an error in the catalog controller - cannot locate catalog_id which I know is in the table. I am now not sure if complex forms is the way to go or I should be looking at another direction to get the appropriate form in place. Any assistance would be appreciated.

  • Reusing slot numbers in Linux software RAID arrays

    - by thkala
    When a hard disk drive in one of my Linux machines failed, I took the opportunity to migrate from RAID5 to a 6-disk software RAID6 array. At the time of the migration I did not have all 6 drives - more specifically the fourth and fifth (slots 3 and 4) drives were already in use in the originating array, so I created the RAID6 array with a couple of missing devices. I now need to add those drives in those empty slots. Using mdadm --add does result in a proper RAID6 configuration, with one glitch - the new drives are placed in new slots, which results in this /proc/mdstat snippet: ... md0 : active raid6 sde1[7] sdd1[6] sda1[0] sdf1[5] sdc1[2] sdb1[1] 25185536 blocks super 1.0 level 6, 64k chunk, algorithm 2 [6/6] [UUUUUU] ... mdadm -E verifies that the actual slot numbers in the device superblocks are correct, yet the numbers shown in /proc/mdstat are still weird. I would like to fix this glitch, both to satisfy my inner perfectionist and to avoid any potential sources of future confusion in a crisis. Is there a way to specify which slot a new device should occupy in a RAID array? UPDATE: I have verified that the slot number persists in the component device superblock. For the version 1.0 superblocks that I am using that would be the dev_number field as defined in include/linux/raid/md_p.h of the Linux kernel source. I am now considering direct modification of said field to change the slot number - I don't suppose there is some standard way to manipulate the RAID superblock?

  • Manipulating columns of numbers in elisp

    - by ~unutbu
    I have text files with tables like this: Investment advisory and related fees receivable (161,570 ) (71,739 ) (73,135 ) Net purchases of trading investments (93,261 ) (30,701 ) (11,018 ) Other receivables 61,216 (10,352 ) (69,313 ) Restricted cash 20,658 (20,658 ) - Other current assets (39,643 ) 14,752 64 Other non-current assets 71,896 (26,639 ) (26,330 ) Since these are accounting numbers, parenthesized numbers indicate negative numbers. Dashes represent 0 or no number. I'd like to be able to mark a rectangular region such as third column above, call a function (format-column), and automatically have (-73135-11018-69313+64-26330)/1000 sitting in my kill-ring. Even better would be -73.135-11.018-69.313+0.064-26.330 but I couldn't figure out a way to transform 64 -- 0.064. This is what I've come up with: (defun format-column () "format accounting numbers in a rectangular column. format-column puts the result in the kill-ring" (interactive) (let ((p (point)) (m (mark)) ) (copy-rectangle-to-register 0 (min m p) (max m p) nil) (with-temp-buffer (insert-register 0) (goto-char (point-min)) (while (search-forward "-" nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward "," nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward ")" nil t) (replace-match "" nil t)) (goto-char (point-min)) (while (search-forward "(" nil t) (replace-match "-" nil t) (just-one-space) (delete-backward-char 1) ) (goto-char (point-min)) (while (search-forward "\n" nil t) (replace-match " " nil t)) (goto-char (point-min)) (kill-new (mapconcat 'identity (split-string (buffer-substring (point-min) (point-max))) "+")) (kill-region (point-min) (point-max)) (insert "(") (yank 2) (goto-char (point-min)) (while (search-forward "+-" nil t) (replace-match "-" nil t)) (goto-char (point-max)) (insert ")/1000") (kill-region (point-min) (point-max)) ) ) ) (global-set-key "\C-c\C-f" 'format-column) Although it seems to work, I'm sure this function is poorly coded. The repetitive calls to goto-char, search-forward, and replace-match and the switching from buffer to string and back to buffer seems ugly and inelegant. My entire approach may be wrong-headed, but I don't know enough elisp to make this more beautiful. Do you see a better way to write format-column, and/or could you make suggestions on how to improve this code?

  • adding only odd numbers

    - by Jessica M.
    So the question I'm trying to solve the user is supposed to enter any positive number. Then I'm trying to write a program that adds only the odd numbers up to the number the user enters and displays the total. So for example if the user enters 4 my program should add four odd numbers. 1 + 3 + 5 + 7 = 16. The only tools I have available are for statement, if, if/else if,while loop and println. I can only figure out how to print out the odd numbers. I know I want to create a variable named total to store the value of adding up all the odd numbers but I don't know how that fits into the program. import acm.program.*; public class AddingOddNumbers extends ConsoleProgram { public void run() { int n = readInt("enter a positive nunber: "); int total = 0; for (int i = 0; i < n; i++) { if (n == 1) { println(1); } else { println((i * 2) + 1); } } } }

  • converting numbers into alphabets.

    - by Nina
    Hi! i want to convert number into alphabets using javascript e.g. 01=n, 02=i 03=n,04=a and when someone enters the numbers:01020304 in the form he will get like this: nina. or whatever he enters it get replace with equivalent alphabets including spaces. i will be really thankful if you can provide full code including html form code as i am beginner. Thank you all for quick response. I have found this code in one site it converts alphabets into numbers, but code for converting numbers into alphabets isn't working. here is a code for converting alphabets into numbers: var i,j; var getc; var len; var num,alpha; num=new Array("01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17", "18","19","20","21","22","23","24","25","26","00","##","$$"); alpha=new Array("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u"," v","w","x","y","z"," ",".",","); function encode() { len=document.f1.ta1.value.length; document.f1.ta2.value=""; for(i=0;i

  • How to map a test onto a list of numbers

    - by Arthur Ulfeldt
    I have a function with a bug: user> (-> 42 int-to-bytes bytes-to-int) 42 user> (-> 128 int-to-bytes bytes-to-int) -128 user> looks like I need to handle overflow when converting back... Better write a test to make sure this never happens again. This project is using clojure.contrib.test-is so i write: (deftest int-to-bytes-to-int (let [lots-of-big-numbers (big-test-numbers)] (map #(is (= (-> % int-to-bytes bytes-to-int) %)) lots-of-big-numbers))) This should be testing converting to a seq of bytes and back again produces the origional result on a list of 10000 random numbers. Looks OK in theory? except none of the tests ever run. Testing com.cryptovide.miscTest Ran 23 tests containing 34 assertions. 0 failures, 0 errors. why don't the tests run? what can I do to make them run?
