  • Does F# have an equivalent to Haskell's take?

    - by McMuttons
    In Haskell, there is a function "take n list" which returns the first n elements from a list. For example "sum (take 3 xs)" sums up the first three elements in the list xs. Does F# have an equivalent? I expected it to be one of the List-functions, but I can't spot anything that seems to match.

  • The least amount of code possible for this MySQL query?

    - by ddan
    I have a MySQL query that: gets data from three tables linked by unique id's. counts the number of games played in each category, from each user and counts the number of games each user has played that fall under the "fps" category It seems to me that this code could be a lot smaller. How would I go about making this query smaller. http://sqlfiddle.com/#!2/6d211/1 Any help is appreciated even if you just give me links to check out.

  • Centralizing / Abstracting MSSQL Data from Multiple Tables / Databases

    - by davemackey
    If one has a number of databases (due to separate application front-ends) that provide a complete picture - for example a CRM, accounting, and product database - what methods are available to centralize/abstract this data for easy reporting? Essentially, I'm wondering if there is a way to automatically pull data from multiple databases into a central repository that is continuously updated from the three databases and which can be used for reporting? I'm also open to alternative best practice suggestions?

    I've been working on this for a couple of hours and can't seem to wrap my head around it. I have three images, below, and I would like the text content to sit on top of these, but how do I do it? The middle image is the image that would need to repeat as the container div expands. Top: Middle repeating: Bottom:

  • How to use enumeration types in C++? Apply within example.

    - by Sagistic
    I do not understand how to use enumeration types. I understand what they are, but I don't quite get their purpose. I have made a program that inputs three sides of a triangle and outputs whether or not they are isosceles, scalene, or equilateral. I'm suppose to incorporate the enumeration type somewhere, but don't get where and how to use them. Any help would be appreciated. // h8p466x1.cpp : Defines the entry point for the console application. // include "stdafx.h" int _tmain(int argc, _TCHAR* argv[]) { return 0; } include using namespace std; enum triangleType {scalene, isosceles, equilateral, noTriangle}; void triangleShape(double x, double y, double z); int main() { double x, y, z; cout << "Please enter the three sides of a triangle:" << endl; cout << "Enter side 1: "; cin >> x; cout << endl; cout << "Enter side 2: "; cin >> y; cout << endl; cout << "Enter side 3: "; cin >> z; cout << endl; triangleShape(x, y, z); return 0; } void triangleShape(double x, double y, double z) { if (((x+y) z) && ((x+z) y) && ((y+z) x)) { cout << "You have a triangle!" << endl; if (x == y && y == z) cout << "Your triangle is an equilateral" << endl; else if (x == y || x == z || y == z) cout << "Your triangle is an isosceles" << endl; else cout << "Your triangle is a scalene" << endl; } else if ((x+y) <= z || ((x+z) <= y) || ((y+z) <= x)) cout << "You do not have a triangle." << endl; }

  • Subversion Question - How to skip a revision...

    - by Albert
    So say I have the three latest revisions of an aspx file: 55,56, and 57. Revision 56 added a feature that I want to remove, but I also want to have the new features deployed in version 57. Is there any way I can merge version 55 with 57, leaving revision 56 out of the picture? If it matters, I'm using Tortoise SVN and Visual SVN, but I normally just use Tortoise. Thanks for any ideas.

  • How to query by recent date and value in SQL?

    - by wsb3383
    I have a table with three columns: patient_id, obs_date, and weight_val. patient_id stores patient identification #, weight_val stores a weight value, and obs_date stores the date when the weight reading was taken. So, a patient can have many different weight readings at different dates. How do you write a query for: select all patients whose last weight reading is 120?

  • What runs before main()?

    - by MikimotoH
    After testing on msvc8, I found: Parse GetCommandLine() to argc and argv Standard C Library initialization C++ Constructor of global variables These three things are called before entering main(). My questions are: Will this execution order be different when I porting my program to different compiler (gcc or armcc), or different platform? What stuff does Standard C Library initialization do? So far I know setlocale() is a must. Is it safe to call standard C functions inside C++ constructor of global variables?

  • A way to make md5_file() faster?

    - by Rob
    I currently use md5_file(); to run through about 15 URLs and verify their MD5. Is there a way I can make this faster? It takes far too long to run through all of them. Sorry if this isn't a good question, I just realized its only three (four if you count this one) sentences long.

  • Implementing search functionality with multiple optional parameters against database table.

    - by quarkX
    Hello, I would like to check if there is a preferred design pattern for implementing search functionality with multiple optional parameters against database table where the access to the database should be only via stored procedures. The targeted platform is .Net with SQL 2005, 2008 backend, but I think this is pretty generic problem. For example, we have customer table and we want to provide search functionality to the UI for different parameters, like customer Type, customer State, customer Zip, etc., and all of them are optional and can be selected in any combinations. In other words, the user can search by customerType only or by customerType, customerZIp or any other possible combinations. There are several available design approaches, but all of them have some disadvantages and I would like to ask if there is a preferred design among them or if there is another approach. Generate sql where clause sql statement dynamically in the business tier, based on the search request from the UI, and pass it to a stored procedure as parameter. Something like @Where = ‘where CustomerZip = 111111’ Inside the stored procedure generate dynamic sql statement and execute it with sp_executesql. Disadvantage: dynamic sql, sql injection Implement a stored procedure with multiple input parameters, representing the search fields from the UI, and use the following construction for selecting the records only for the requested fields in the where statement. WHERE (CustomerType = @CustomerType OR @CustomerType is null ) AND (CustomerZip = @CustomerZip OR @CustomerZip is null ) AND ………………………………………… Disadvantage: possible performance issue for the sql. 3.Implement separate stored procedure for each search parameter combinations. Disadvantage: The number of stored procedures will increase rapidly with the increase of the search parameters, repeated code.

  • Multiple branch merges, stick with Subversion or move to Mercurial or Git?

    - by casualcoder
    Given a situation where there are three branches, A, B and C, where A is merged to both B and C on a regular basis. From time to time B is merged to C. With Subversion, B apparently must be removed and recreated after every merge to C. This raises groans from colleagues, but would any alternative do any better? It would seem to me that Mercurial would not. Perhaps Git? Does anyone else run into this problem?

  • Matching Strings: a biological perspective

    - by sun
    Write a function, called constrainedMatchPair which takes three arguments: a tuple representing starting points for the first substring, a tuple representing starting points for the second substring, and the length of the first substring. The function should return a tuple of all members (call it n) of the first tuple for which there is an element in the second tuple (call it k) such that n+m+1 = k, where m is the length of the first substring. Complete the definition def constrainedMatchPair(firstMatch,secondMatch,length):

  • Swing: easiest way to align width of [dynamic][static][dynamic] components?

    - by java.is.for.desktop
    What is the easiest way in standard Java Swing to align three components in such a way that: the dynamic widths of Component1 and Component3 are adjusted to be equal, while Component2 (which is in between) has constant width? Imagine we have some resizable JPanel (such as inside a JFrame). Small width should look like this: [----------------whole JPanel----------------] [--Component1--] [Component2] [--Component3--] Big width should look like this: [------------------------whole JPanel------------------------] [------Component1------] [Component2] [------Component3------] Note: I just "trialed-and-errored" with GroupLayout for too long.
