  • complex mysql rank !

    - by silversky
    I have a tb with this col: ein, los, id ... I whant to order the table by this index: win / ( win + los ) * 30 + win / SUM(win) * 70 and then to find the rank for two id's. I'm not very good on mysql, so whath I wrote it's totally wrong: $stmt=$con-prepare("SET @rk := 0"); $stmt=$con-prepare("SELECT rank, id FROM ( SELECT @rk := @rk + 1 AS rank, (win/(win+los)*30+win/SUM(win)*70) AS index, win, los, id FROM tb_name ORDER BY index DESC) as result WHERE id=? AND id=?"); $stmt - bind_param ("ii", $id1, $id2); $stmt - execute(); $stmt - bind_result($rk, $idRk); And also this query it supouse to run maybe every 5-10 sec for every user, so I'm trying to find something very, very fast. if it's necesary I could add, change, delete any column, in order to be as faster as posible.

  • how to sort a multidemensional array by an inner key

    - by Derek Vance
    i have this enormous array that i am pulling from an API for BattleField Bad Company 2, and the soldier stats can be pulled as a multi dimensional array with an inner array for each soldier, however the API sormats it sorting the soldiers by name alphabetically, i want to sort them by rank (which is just another key within that soldiers array). ive been trying to figure this out for days, anyone have any ideas? (ie sort the array by $arr[players][][rank] here is a bit of the array Array ( [players] = Array ( [0] = Array ( [name] = bigjay517 [rank] = 29 [rank_name] = SECOND LIEUTENANT II [veteran] = 0 [score] = 979440 [level] = 169 [kills] = 4134 [deaths] = 3813 [time] = 292457.42 [elo] = 319.297 [form] = 1 [date_lastupdate] = 2010-03-30T14:06:20+02:00 [count_updates] = 13 [general] = Array ( [accuracy] = 0.332 [dogr] = 86 [dogt] = 166 [elo0] = 309.104 [elo1] = 230.849 [games] = 384 [goldedition] = 0 [losses] = 161 [sc_assault] = 146333 [sc_award] = 567190 [sc_bonus] = 35305 [sc_demo] = 96961 [sc_general] = 264700 [sc_objective] = 54740 [sc_recon] = 54202 [sc_squad] = 53210 [sc_support] = 70194 [sc_team] = 21215 [sc_vehicle] = 44560 [slevel] = 0 [spm] = 0 [spm0] = 0 [spm1] = 0 [srank] = 0 [sveteran] = 0 [teamkills] = 67 [udogt] = 0 [wins] = 223 )

  • Pros and cons of using JSON for WCF service

    - by brz dot net
    What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

  • CurvyCorners in Wordpress Theme only rounds some corners in IE - what am I doing wrong?

    - by user346602
    Hi, I'm implementing the CurvyCorners script on a blog I'm developing. The script works in IE on some parts of the blog, but not others. I've used the following code to add it to the functions.php file (as suggested by someone smarter than me): function load_curvy_corners() { wp_enqueue_script('curvycorners', get_bloginfo('stylesheet_directory') .'/scripts /curvycorners.src.js','','',true); } add_action('init', 'load_curvy_corners'); Here is the site I'm working on: http://www.bellissimafashions.com/blog/ The container and logo area appear rounded in IE, but the navigation area is still square and seems to take awhile to load now. I don't know if this has something to do with the fact the theme I'm using (Pure II by beathemes) has placed the left side in the footer.php?

  • Static Evaluation Function for Checkers

    - by Kamikaze
    Hi all! I'm trying to write an evaluation function for a game of checkers that I'm developing but I can't find the right documentation. I've read several documents on the web witch describe different techniques for either writing one or letting the computer find it(using genetic algorithms or Bayesian learning) but they're too complicated for a novice like me. All documents pointed a reference to "Some studies in machine learning using the game of checkers" by A.L.Samuel but I couldn't get my hands on it yet :(. I've only read the follow up "Some studies in machine learning using the game of checkers -II" and found some good info there, but it doesn't explain what the eval parameters mean (I think I don't have the whole article). Thanks for your help!

  • Deadlock error in INSERT statement

    - by Gnanam
    We've got a web-based application. There is a time-bound database operation (INSERTs and UPDATEs) in the application which takes more time to complete, hence this particular flow has been changed into Java Thread so it will not wait (block) for the complete database operation to be completed. My problem is, if more than 1 user come across this particular flow, I'm facing the following error thrown by PostgreSQL: org.postgresql.util.PSQLException: ERROR: deadlock detected Detail: Process 13560 waits for ShareLock on transaction 3147316424; blocked by process 13566. Process 13566 waits for ShareLock on transaction 3147316408; blocked by process 13560. Above error is consistently thrown in INSERT statements.

  • How to judge the relative efficiency of algorithms given runtimes as functions of 'n'?

    - by Lopa
    Consider two algorithms A and B which solve the same problem, and have time complexities (in terms of the number of elementary operations they perform) given respectively by a(n) = 9n+6 b(n) = 2(n^2)+1 (i) Which algorithm is the best asymptotically? (ii) Which is the best for small input sizes n, and for what values of n is this the case? (You may assume where necessary that n0.) i think its 9n+6. guys could you please help me with whether its right or wrong?? and whats the answer for part b. what exactly do they want?

  • C# -Interview Question Anonymous Type

    - by Amutha
    Recently i was asked to prove the power of C# 3.0 in a single line( might be tricky) i wrote new int[] { 1, 2, 3 }.Union(new int[]{10,23,45}). ToList().ForEach(x => Console.WriteLine(x)); and explained you can have (i) anonymous array (ii) extension method (iii)lambda and closure all in a single line.I got spot offer. But..... The interviewer asked me how will you convert an anonymous type into know type :( I am 100% sure ,we can not do that.The interviewer replied there is 200% chance to do that if you have a small work around.I was clueless. As usual,I am waiting for your valuable reply(Is it possible?).

  • After I've installed it, NUnit doesn't appear in VS2008

    - by Richard77
    Hello, I downloaded and installed NUnit successfuly (or so I was told by the installer). Now, when I start a project, I don't see NUnit in the 'Create UnitTest' prompt as one the choice I'm givven to. All I can see are (i) VS Unit Test and (ii) Mb Unit v3 as choices. In fact, I downloaded today the MbB Unit. After, installing it, I was able to see it right away in the prompt. What happen to the NUnit? Althought, I can see it when I do Start - All Programs Or maybe NUnit dosn't need to appear in the prompt as choice since it has its own GUI. Thanks for helping

  • Access Elements inside a DataTemplate... How to for more than 1 DataTemplate?

    - by GaaTY
    I've got 2 DataTemplates defined for a Listbox Control. 1 Template is for the UnSelected State and the other one is for the Selected State(showing more detail than the UnSelected State). I followed the example here: http://blogs.msdn.com/b/wpfsdk/archive/2007/04/16/how-do-i-programmatically-interact-with-template-generated-elements-part-ii.aspx about how to access the Elements inside the DataTemplates from Code behind. I get it right, but it only finds and returns an element of the UnSelected DataTemplate. But when i search for an element in the Selected DataTemplate i get a NullReferenceException. What could i be doing wrong?

  • Disabling single line copy in Visual Studio

    - by erlando
    Is there anyway to disable the rather annoying feature that Visual Studio (2008 in my case) has of copying the line (with text on it) the cursor is on when CTRL-C is pressed and no selection is made? I know of the option to disable copying blank lines. But this is driving me crazy as well. ETA: I'm not looking to customize the keyboard shortcut. ETA-II: I am NOT looking for "Tools-Options-Text Editor-All Languages-Apply cut or copy to blank lines...".

  • Combine Hibernate class with @Bindable for SwingBuilder without Griffon?

    - by Misha Koshelev
    Dear All: I have implemented a back-end for my application in Groovy/Gradle, and am now trying to implement a GUI. I am using Hibernate for my data storage (with HSQLDB) per http://groovy.codehaus.org/Using+Hibernate+with+Groovy (with Jasypt for encryption) and it is working quite well. I was wondering if there are any good tips for using @Bindable with, e.g., an @Entity class such as @Entity class Book { @Id @GeneratedValue(strategy = GenerationType.AUTO) public Long id @OneToMany(cascade=CascadeType.ALL) public Set<Author> authors public String title String toString() { "$title by ${authors.name.join(', ')}" } } or if I am: (i) asking for Griffon (ii) completely on the wrong track? Thank you! Misha

  • How can I update a row and insert a new one automatically in NHibernate with one call to Save?

    - by snicker
    Let's say I have a Type II SCD database, that is basically append only. I am using NHibernate to persist objects to my database. I have an object like so: Pony |- int Id |- Guid EntityId |- string PonyName |- string PonyColor |- int RevisionValidFrom |- int RevisionValidTo Here's a typical scenario: Pony myLittlePony = myStable.GetLatestPonyByGuid("0f1ac08a-3328-43db-b278-77c272e4fea3"); myLittlePony.PonyColor = "Fish"; myNHSession.Save(myLittlePony); I want to be able to call Session.Save(myLittlePony) and have NHibernate UPDATE the old entity's RevisionValidTo to whatever I specify and then INSERT the modified Pony as a new row with a new Id, basically as if it were a brand new object being persisted to the DB.

  • Identifying CDs

    - by Chris
    I'd like to be able to determine what music album CD is in a CD drive. For example, if someone claims that the CD in their drive is Eminem - The Eminem Show, I would like to be able to verify that the CD is indeed The Eminem Show. Any ideas? I've applied for a Gracenote developer license, but they won't get back to me for five days. Also, how does this work? Is there some GUID or other unique identifier that music discs are encoded with? Lastly, might this be possible with data CDs, like, say, the Diablo II install Disc 1? If so, any directions you can point me in, for accomplishing this?

  • creating a color coded time chart using colorbar and colormaps in python

    - by Rusty
    I'm trying to make a time tracking chart based on a daily time tracking file that I used. I wrote code that crawls through my files and generates a few lists. endTimes is a list of times that a particular activity ends in minutes going from 0 at midnight the first day of the month to however many minutes are in a month. labels is a list of labels for the times listed in endTimes. It is one shorter than endtimes since the trackers don't have any data about before 0 minute. Most labels are repeats. categories contains every unique value of labels in order of how well I regard that time. I want to create a colorbar or a stack of colorbars (1 for eachday) that will depict how I spend my time for a month and put a color associated with each label. Each value in categories will have a color associated. More blue for more good. More red for more bad. It is already in order for the jet colormap to be right, but I need to get desecrate color values evenly spaced out for each value in categories. Then I figure the next step would be to convert that to a listed colormap to use for the colorbar based on how the labels associated with the categories. I think this is the right way to do it, but I am not sure. I am not sure how to associate the labels with color values. Here is the last part of my code so far. I found one function to make a discrete colormaps. It does, but it isn't what I am looking for and I am not sure what is happening.

  • Android framework. What is it?

    - by Confused
    I've few questions on Android Framework. Can someone please answer them i) What does an Android Framework do? What is it's job? ii) What are these managers - Activity Manager, Location Manager etc? Are they APIs or libraries? iii) I heard that the definition of a framework is - a set of libraries that say “Don’t call us, we’ll call you.” So can I say that Activity Manager, Location Manager etc are such libraries? Or is it that they are not libraries but APIs (used to access underlying c/c++ libraries) and the actual libraries that do "Don't call us, we'll call you." are hidden from us?

  • Loading Fact Table + Lookup / UnionAll for SK lookups.

    - by Nev_Rahd
    I got to populate FactTable with 12 lookups to dimension table to get SK's, of which 6 are to different Dim Tables and rest 6 are lookup to same DimTable (type II) doing lookup to same natural key. Ex: PrimeObjectID = lookup to DimObject.ObjectID = get ObjectSK and got other columns which does same OtherObjectID1 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID2 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID3 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID4 = lookup to DimObject.ObjectID = get ObjectSK OtherObjectID5 = lookup to DimObject.ObjectID = get ObjectSK for such multiple lookup how should go in my SSIS package. for now am using lookup / unionall foreach lookup. Is there a better way to this.
