  • SQL Group By Modulo of Row Count

    - by Alex Czarto
    I have the following sample data: Id Name Quantity 1 Red 1 2 Red 3 3 Blue 1 4 Red 1 5 Yellow 3 So for this example, there are a total of 5 Red, 1 Blue, and 3 Yellow. I am looking for a way to group them by Color, but with a maximum of 2 items per group (sorting is not important). Like so: Name QuantityInPackage Red 2 Red 2 Red 1 Blue 1 Yellow 2 Yellow 1 Any suggestions on how to accomplish this using T-SQL on MS-SQL 2005?

  • how to precompile a jquery ui autocomplete widget?

    - by Alex
    Hello, I have a jquery ui autocomplete widget in a form and I'd like to preselect its value from a database. My autocomplete works in the following way: the id is a number, tha label and the value are the same and are a concatenation of id + " - " + description. When a value from the autocomplete is selected, a hidden field's value is set to the value of id. Then, the hidden field value is saved to the db when the form is submitted. When the user comes back on the page for editing, I need to reload the value from the db: I set the idden field value again and then I would like to precompile the value of the autocomplete widget with the concatenation of id + " - " + description taken form the db. I think I should trigger the event of selecting a row in the autocomplete, but I don't know how to do. Do you have any ideas? Thank you Here is the code of the autocomplete: $('#codice_contratto').autocomplete({ source: 'do_contratto.php', select: function(event, ui) { $('#id_contratto').val(ui.item.id); } });

  • how to specify which port to use using INET in perl

    - by alex
    Hi: I am using perl INET to create inter-process communication in my program. I need to use a specific port number in my TCP client. I was following the example in Perl doc, but it doesn't work. Here is my code: old code(working): tx_socket = new IO::Socket::INET-new('127.0.0.1:8001') || die "Can't connect to 127.0.0.1:8001 : $!\n"; new code(not working): tx_socket = new IO::Socket::INET-new('127.0.0.1:8001', LocalPort=9000 ) || die "Can't connect to 127.0.0.1:8001 : $!\n"; Does anyone know what's wrong? Thanks

  • Is there a PHP benchmark that meets these specific criteria? [closed]

    - by Alex R
    I'm working on a tool which converts PHP code to Scala. As one of the finishing touches, I'm in need of a really good (er, somewhat biased) benchmark. By dumb luck my first benchmark attempt was with some code which uses bcmath extensively, which unfortunately is 1000x slower in Java, making the Scala code 22x slower overall than the original PHP. So I'm looking for some meaningful PHP benchmark with the following characteristics: The PHP source needs to be in a single file. It should solve a real-world problem. No silly looping over empty methods etc. I need it to be simple to setup - no databases, hard-to-find input files, etc. Simple text input and output preferred. It should not use features that are slow in Java (BigInteger, trigonometric functions, etc). It should not use exoteric or dynamic PHP functions (e.g. no "eval" or "variable vars"). It should not over-rely on built-in libraries, e.g. MD5, crypt, etc. It should not be I/O bound. A CPU-bound memory-hungry algorithm is preferred. Basically, intensive OO operations, integer and string manipulation, recursion, etc would be great. Thanks

  • How do I add programmatically-generated new files to source control?

    - by Alex Basson
    This is something I've never really understood about source control, specifically Subversion (the only source control I've ever used, which isn't saying much). I'm considering moving to git or Mercurial, so if that affects the answer to my question, please indicate as such. Ok. As I understand it, every time I create a new file, I have to tell SVN about it, so that it knows to add it to the repository and place it under control. Something like: svn add newfile That's fine if I'm the one creating the file: I know I created it, I know its name, I know where it lives, so it's easy to tell SVN about it. But now suppose I'm using a framework of some kind, like Rails, Django, Symfony, etc., and suppose I've already done the initial commit. All of these frameworks create new files programmatically, often many at once, in different directories, etc. etc. How do I tell the source control about these new files? Do I have to hunt each one of them down individually and add them? Is there an easier way? (Or am I possibly misunderstanding something fundamental about source control?)

  • ASP.NET EnqityDataSource WhereParameters, creates new property.

    - by Alex
    I am trying to populate GridView, using EntityDataSource(code behind), I need to able to sort GridView. However when I sort i get error: A property with name 'aspnet_Users.UserId1' does not exist in metadata for entity type So I beleive it is because I generate where parameter in code behind: ActiveEnqDataSource.WhereParameters.Add(new SessionParameter("aspnet_Users.UserId", TypeCode.Object, "UserName")); Full code is : ActiveEnqDataSource.ConnectionString = db.Connection.ConnectionString; ActiveEnqDataSource.DefaultContainerName = "Entities"; ActiveEnqDataSource.EntitySetName = "Enquiries"; ActiveEnqDataSource.Include = "UserCars.CarModel.CarMake, Category, aspnet_Users"; ActiveEnqDataSource.EnableUpdate = true; ActiveEnqDataSource.EnableInsert = true; ActiveEnqDataSource.EnableDelete = true; ActiveEnqDataSource.AutoGenerateWhereClause = true; ActiveEnqDataSource.WhereParameters.Add(new SessionParameter("aspnet_Users.UserId", TypeCode.Object, "UserName")); Any suggestions? Thank you very much! The gridview itself renders perfectly, only thing I cannot sort it, any "whereParameters" I add, Add 1 to the property e.g UserId1,EnquiryStatus1, ProdauctName1. etc...

  • How to copy matplotlib figure?

    - by Alex
    I have FigureCanvasWxAgg instance with a figure displayed on a frame. If user clicks on the canvas another frame with a new FigureCanvasWxAgg containing the same figure will be shown. By now closing the new frame can result in destroying the C++ part of the figure so that it won't be available for the first frame. How can I save the figure? Python deepcopy from copy module does't work in this case. Thanks in advance.

  • Why scala not allowing '$' identifier in case statement?

    - by Alex R
    this works as expected scala 3 match { case x:Int = 2*x } res1: Int = 6 why does this fail? scala 3 match { case $x:Int = 2*$x } :1: error: '=' expected but ':' found. 3 match { case $x:Int = 2*$x } ^ scala 3 match { case `$x`:Int = 2*$x } :1: error: '=' expected but ':' found. 3 match { case `$x`:Int = 2*$x } ^ scala 3 match { case `$x` : Int = 2*$x } :1: error: '=' expected but ':' found. 3 match { case `$x` : Int = 2*$x } '$' is supposed to be a valid identifier character, as demonstrated here: scala var y = 1 y: Int = 1 scala var $y = 2 $y: Int = 2 Thanks

  • What is the MacVim default font?

    - by Alex
    Hey there, I love using macvim, and I really like the default font, but at work I recently got some bigger monitors, and I want to make the text bigger. It says in the macvim docs that it is Bitstream Vera, but trying to set the font like so: :set guifont=Bitstream\ Vera\ Sans\ Mono:h16 results in an invalid font(s) error. So what is the default font then? I'm running the latest version of macvim and I am running Snow Leopard. Thanks!!

  • How to walk through two files simultaneously in Perl?

    - by Alex Reynolds
    I have two text files that contain columnar data of the variety position-value. Here is an example of the first file (file A): 100 1 101 1 102 0 103 2 104 1 ... Here is an example of the second file (B): 20 0 21 0 ... 100 2 101 1 192 3 193 1 ... Instead of reading one of the two files into a hash table, which is prohibitive due to memory constraints, what I would like to do is walk through two files simultaneously, in a stepwise fashion. What this means is that I would like to stream through lines of either A or B and compare position values. If the two positions are equal, then I perform a calculation on the values associated with that position. Otherwise, if the positions are not equal, I move through lines of file A or file B until the positions are equal (when I again perform my calculation) or I reach EOF of both files. Is there a way to do this in Perl?

  • Can one use polygon() or equivalent in lattice and ggplot2 plots?

    - by Alex Reynolds
    Is it possible to annotate lattice (or ggplot2) figures with elements created with polygon() (or elements created with a similar function) from the graphics library? I'm not too familiar with either library beyond examples of simple graphs posted on the web and printed in Deepayan Sarkar's book. Therefore, while I have code for what I've been doing in R with the graphics library, pointing me to relevant, equivalent functions and usage examples for lattice or ggplot2 specifically would be appreciated. Thanks.

  • Setting up DomainKeys/DKIM in a PHP-based SMTP client

    - by Alex
    It looks like there are some great libraries out there to do DomainKeys signing of emails on C#/.NET, but I'm having a really hard time finding the same kind of support for PHP. Maybe I'm not looking in the right place? The only one I found is http://php-dkim.sourceforge.net/; it looks incredibly hacky and supports PHP4 only. Considering how popular PHP is, and how critical DomainKeys are for email classification as non-spam, I'd expect better tools; do you know of any? Any other tricks you'd recommend?
