• What should the accessablity of Fields in a Abstract Class be?

  - by James McMahon

  To put it simply as an example, public abstract class AbstractFellow { protected Thing buddy; .... public class ConcreteFellow extends AbstractFellow { public void someMethod() { buddy.doSomething(); //OR buddy = somethingElse; //OR somethingElse = buddy; } } Is this bad practice?

• jQuery selector for document and another element

  - by James

  Can I merge these in jQuery? I'm using the HotKeys plugin. $(document).bind('keydown', 'n', cycleNoise); $(document).bind('keydown', 's', pickRandom); $(document).bind('keydown', 'v', toggleTasks); $(document).bind('keydown', 't', toggleTimer); $(document).bind('keydown', 'up', hideTask); $(document).bind('keydown', 'down', nextTask); $('#duration').bind('keydown', 't', toggleTimer); $('#duration').bind('keydown', 'n', cycleNoise); $('#duration').bind('keydown', 's', pickRandom); $('#duration').bind('keydown', 'v', toggleTasks); $('#duration').bind('keydown', 'up', hideTask); $('#duration').bind('keydown', 'down', nextTask); In other words, is it possible to use document and '#duration' in the same selector. The following doesn't seem to work: $(document + ',#duration').bind(...);

• Reformat SQLGeography polygons to JSON

  - by James

  I am building a web service that serves geographic boundary data in JSON format. The geographic data is stored in an SQL Server 2008 R2 database using the geography type in a table. I use [ColumnName].ToString() method to return the polygon data as text. Example output: POLYGON ((-6.1646509904325884 56.435153006374627, ... -6.1606079906751 56.4338050060666)) MULTIPOLYGON (((-6.1646509904325884 56.435153006374627 0 0, ... -6.1606079906751 56.4338050060666 0 0))) Geographic definitions can take the form of either an array of lat/long pairs defining a polygon or in the case of multiple definitions, an array or polygons (multipolygon). I have the following regex that converts the output to JSON objects contained in multi-dimensional arrays depending on the output. Regex latlngMatch = new Regex(@"(-?[0-9]{1}\.\d*)\s(\d{2}.\d*)(?:\s0\s0,?)?", RegexOptions.Compiled); private string ConvertPolysToJson(string polysIn) { return this.latlngMatch.Replace(polysIn.Remove(0, polysIn.IndexOf("(")) // remove POLYGON or MULTIPOLYGON .Replace("(", "[") // convert to JSON array syntax .Replace(")", "]"), // same as above "{lng:$1,lat:$2},"); // reformat lat/lng pairs to JSON objects } This is actually working pretty well and converts the DB output to JSON on the fly in response to an operation call. However I am no regex master and the calls to String.Replace() also seem inefficient to me. Does anyone have any suggestions/comments about performance of this?

• PHP preg_replace - Don't match within h1 tags

  - by James

  Hi there. I am using preg_replace to add a link to keywords if they are found within a long HTML string. I don't want to add a link if the keyword is found within h1 tags or strong tags. The below regex nearly works and basically says (I think): If the keyword is not immediately wrapped by either a h1 tag or a strong tag then replace with the keyword that was matched, as a bolded link to google. $result = preg_replace('%(?!<h1>)(?!<strong>)\b(bobs widgets)\b(?!<\/strong>)(?!<\/h1>)%i','<a href="http://www.google.com"><strong>$1</strong></a>', $result, -1); (the reason I don't want to match if in strong tags is because I am recursing through a lot of keywords so don't want to link an already linked keyword on subsequent passes) the above works fine and won't match: <h1>bobs widgets</h1> It will however match the keyword in the following text, because the h1 tag isn't immediately either side of the keyword: <h1>Here are bobs widgets for sale</h1> I need to make the spaces either side optional and have tried adding \s* but that doesn't get me anywhere. I'd be very grateful for a push in the right direction here.

• How to structure an enterprise MVC app, and where does Business Logic go?

  - by James

  I am an MVC newbie. As far as I can tell: Controller: deals with routing requests View: deals with presentation of data Model: looks a whole lot like a Data Access layer Where does the Business Logic go? Take a large enterprise application with: Several different sources of data (WCF, WebServices and ADO) tied together in a data access layer (useing multiple different DTOs). A lot business logic segmented over several dlls. What is an appropriate way for an MVC web application to sit on top of this (in terms of code and project structure)? The example I have seen where everything just goes in the Model folder don't seem like they are appropriate for very large applications. Thanks for any advice!

• What's a good Java API for creating Word documents?

  - by Bill James

  I have a new app I'll be working on where I have to generate a Word document that contains tables, graphs, a table of contents and text. What's a good API to use for this? How sure are you that it supports graphs, ToCs, and tables? What are some hidden gotcha's in using them? Some clarifications: I can't output a PDF, they want a Word doc. They're using MS Word 2003 (or 2007), not OpenOffice Application is running on *nix app-server It'd be nice if I could start with a template doc and just fill in some spaces with tables, graphs, etc. Thanks for the help. Edit: Several good answers below, each with their own faults as far as my current situation. Hard to pick a "final answer" from them. Think I'll leave it open, and hope for better solutions to be created. Edit: The OpenOffice UNO project does seem to be closest to what I asked for. While POI is certainly more mainstream, it's too immature for what I want.

• how to get SSRS 2008 R2 to export/render in Excel 2007 format?

  - by James Manning

  I have a report that has ~1k columns and ~17k rows and I'm trying to render it to Excel 2007 with SSRS 2008 R2 Nov CTP. SSRS team members have mentioned in multiple places that Excel 2007 format is included in 2008 R2, for instance: http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/69545568-73cb-4f4c-8f35-44472ba6d013 Now, it's certainly possible that it just hasn't made it into the product yet (at least as of Nov CTP), and if that's the case, that would be good to know, too (and ideally when it would be in the product). The repro report and data (along with attempts showing the existing interface still does Excel 2003 format) are attached to the bottom of this blog post, FWIW: http://cid-456117cf53a42144.spaces.live.com/default.aspx

• Using IvyDE with different workspaces on different branches

  - by James Woods

  I am having problems using IvyDE when I have different workspaces for different branches. I have "Resolve dependencies in workspace" switched on. But everytime I change to a different workspace I have to remember to manually clean the caches out. This is because IvyDE always uses the default cache for resolving dependencies within a workspace, so when switching between workspaces the cache can be polluted by different versions. It would seem that it is impossible to work with two different workspaces at the same time. I cannot find a way to configure the location that IvyDE uses to cache the project dependencies. It does not appear to use the caches defined in the ivysettings.xml

• How do chains work in Rainbow tables?

  - by James Moore

  Hello, I was wondering if should one could explain in detail how chains work in rainbow tables as though you would a complete novice but with relevance to programming. I understand that a chain is 16 bytes long. 8 bytes mark the starting point and 8 mark the end. I also understand that in the filename we have the chain length i.e. 2400. Which means that between our starting point and end point in just 16 bytes we have 2400 possible clear texts? What? How does that work? in those 16 bytes how do i get my 2400 hashes and clear texts or am i miss understanding this? Your help is greatly appreciated. Thanks P.s. I have read the related papers and googled this topic a fair bit. I think im just missing something important to make these gears turn.

• Yaml::load_file acting different between development and production (Rails)

  - by James

  Hi, I am completely stumped at the nature of this problem. We export data from our application into a 'cleaned' YAML file (stripping out IDs, created_at etc). Then we (will) allow users to import these files back into the application - it is the import that is completely bugging me out. In development, YAML::load_file(params[:uploaded_data].local_path) returns an array of YAML::Objects's (and it doesn't matter which of the number of different ways the file could be loaded): [#{"exception_count"="0", "title"="Start", "amount"="70.00", "colour"=nil, "repeat_type_id"="0", "repeat_interval"="1"}}, etc etc] Which is very nice, as the attributes also include the (associated model) exceptions that you see an exception_count for. However on production (rails 2.3.2, running REE 1.8.7 and 1.8.6 for testing, tested on two different production env's, and running production locally) it returns an array of the Objects within the YAML - in this case, Event: [#, repeat_type_id: 0, colour: nil, repeat_interval: 1, exception_count: 0, etc etc] Now this would be just perplexing if it also included the associated model Exception with it - however it doesn't. Can anyone at all shed some light on why the Yaml parser would behave so differently between production and development? I'm on rails 2.3.2, running REE 1.8.7; however I've also tested running Ruby 1.8.6 with exactly the same results. Thanks for any help!

• MySQL Cursor Issue

  - by James Inman

  I've got the following code - this is the first time I've really attempted using cursors. DELIMITER $$ DROP PROCEDURE IF EXISTS demo$$ DROP TABLE IF EXISTS temp$$ CREATE TEMPORARY TABLE temp( id INTEGER NOT NULL AUTO_INCREMENT, start DATETIME NOT NULL, end DATETIME NOT NULL, PRIMARY KEY(id) ) $$ CREATE PROCEDURE demo() BEGIN DECLARE done INT DEFAULT 0; DECLARE a, b DATETIME; DECLARE cur1 CURSOR FOR SELECT MAX(end) AS end FROM ( SELECT id, start, end, @r := @r + (start > @edate) AS num, @edate := GREATEST(@edate, end) FROM ( SELECT @r := 0, @edate := '0001-01-01' ) vars, student_lectures WHERE ( student_id = 1 AND start >= '2010-04-26 00:00:00' AND end <= '2010-04-30 23:59:59' ) ORDER BY start ) q GROUP BY num; DECLARE cur2 CURSOR FOR SELECT MIN(start) AS start FROM ( SELECT id, start, end, @r := @r + (start > @edate) AS num, @edate := GREATEST(@edate, end) FROM ( SELECT @r := 0, @edate := '0001-01-01' ) vars, student_lectures WHERE ( student_id = 1 AND start >= '2010-04-26 00:00:00' AND end <= '2010-04-30 23:59:59' ) ORDER BY start ) q GROUP BY num LIMIT 1, 18446744073709551615; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; OPEN cur1; OPEN cur2; REPEAT FETCH cur1 INTO a; FETCH cur2 INTO b; IF NOT done THEN INSERT INTO temp(start, end) VALUES(a,b); END IF; UNTIL done END REPEAT; CLOSE cur1; CLOSE cur2; END $$ SELECT * FROM temp; I'm not getting anything outputted into the temp table.

• VS2008 DataSet Wizard doesn't match tables for updating

  - by James H

  Hi all, first question ever on this site. I've been having a real stubborn problem using Visual Studio 2008 and I'm hoping someone has figured this out before. I have 2 libraries and 1 project that use strongly typed datasets (MSSQL backend) that I generated using the "Configure DataSet with Wizard" option on in Data Sources. I've had them working just fine for awhile and I've written a lot of code in the non-designer file for the row classes. I've also specified a lot of custom queries using the dataset designer. This is all work I can't afford to loose. I've recently made some changes to re-organize my libraries which included changing the names of the libraries themselves. I also changed the connection string to point to a different database which is a development copy (same exact schema). Problem is now when I open up "Configure DataSet with Wizard" to pickup a new column I've added to one of the tables it no longer matches the tables correctly in the wizard. The wizard displays all of the tables in the database and none of them have check boxes next to them (ie: are not part of this dataset). Below those it shows all of the tables again but with red Xs and these are checked. Basically meaning that Visual Studio sees all of the tables it currently has in the DataSet and sees all of the tables in the database, but believes they are no longer the same and thus do not match! I've had this same thing happen quite awhile back and I think I just re-built the xsd from scratch and manually copied the code over and then had to redefine all of the custom queries I built in the dataset designer. That's not a good solution. I'm looking for 2 answers: 1. What causes this to happen and how to prevent it. 2. How do I fix this so that the wizard once again believes the tables in its xsd are the same tables that are in the database (yes, they have the exact same names still). Thanks.

• Overview of PHP shorthand

  - by James Simpson

  I've been programming in PHP for years now, but I've never learned how to use any shorthand. I come across it from time to time in code and have a hard time reading it, so I'd like to learn the different shorthand that exists for the language sot hat I can read it and start saving time/lines by using it, but I can't seem to find a comprehensive overview of all of the shorthand. A Google search pretty much exclusively shows the shorthand for if/else statements, but I know there must be more than just that. By shorthand, I am talking about stuff like: ($var) ? true : false;

• Templates, and C++ operator for logic: B contained by set A

  - by James Morris

  In C++, I'm looking to implement an operator for selecting items in a list (of type B) based upon B being contained entirely within A. In the book "the logical design of digital computers" by Montgomery Phister jr (published 1958), p54, it says: F11 = A + ~B has two interesting and useful associations, neither of them having much to do with computer design. The first is the logical notation of implication... The second is notation of inclusion... This may be expressed by a familiar looking relation, B < A; or by the statement "B is included in A"; or by the boolean equation F11= A + ~B = 1. My initial implementation was in C. Callbacks were given to the list to use for such operations. An example being a list of ints, and a struct containting two ints, min and max, for selection purposes. There, selection would be based upon B = A-min && B <= A-max. Using C++ and templates, how would you approach this after having implemented a generic list in C using void pointers and callbacks? Is using < as an over-ridden operator for such purposes... <ugh> evil? </ugh> (or by using a class B for the selection criteria, implementing the comparison by overloading ?)

• [Flex Beginner question] String and value object

  Hi all, In php we can assign a method name to a variable and then use that variable to call the method. For example: $image_create_func = 'ImageCreateFromGIF'; $newImage = $image_create_func($oldImage); But can we do this in Flex? In flex, I have the string public var key:String = "email" And I also have a value object searchTerm:SearchTermVO which has a public property "email" (searchTerm.email). Now I want to do searchTerm.email by doing something like in php: searchTerm.key but it's not possible. Can anybody help me with this plz? Thank you.

• How to stop .Net HttpWebRequest.GetResponse() raising an exception

  - by James

  Surely, surely, surely there is a way to configure the .Net HttpWebRequest object so that it does not raise an exception when HttpWebRequest.GetResponse() is called and any 300 or 400 status codes are returned? Jon Skeet does not think so, so I almost dare not even ask, but I find it hard to believe there is no way around this. 300 and 400 response codes are valid responses in certain circumstances. Why would we be always forced to incur the overhead of an exception? Perhaps there is some obscure configuration setting that evaded Jon Skeet? Perhaps there is a completely different type of request object that can be used that does not have this behavior? (and yes, I know you can just catch the exception and get the response from that, but I would like to find a way not to have to). Thanks for any help

• How do I so a select input for a STI column in a Rails model?

  - by James A. Rosen

  I have a model with single-table inheritance on the type column: class Pet < ActiveRecord::Base TYPES = [Dog, Cat, Hamster] validates_presence_of :name end I want to offer a <select> dropdown on the new and edit pages: <% form_for @model do |f| %> <%= f.label :name %> <%= f.text_input :name %> <%= f.label :type %> <%= f.select :type, Pet::TYPES.map { |t| [t.human_name, t.to_s] } %> <% end %> That gives me the following error: ActionView::TemplateError (wrong argument type String (expected Module)) I read a suggestion to use an alias for the field #type since Ruby considers that a reserved word that's the same as #class. I tried both class Pet < ActiveRecord::Base ... alias_attribute :klass, :type end and class Pet < ActiveRecord::Base ... def klass self.type end def klass=(k) self.type = k end end Neither worked. Any suggestions? Oddly, it works fine on my machine (MRI 1.8.6 on RVM), but fails on the staging server (MRI 1.8.7 not on RVM).

• Downloading a file in ASP.NET (through the server) while streaming it to the user

  - by James Teare

  My ASP.NET website currently downloads a file from a remote server to a local drive, although when users access the site they have to wait for the server to finish downloading the file until they can then download the file from my ASP.NET website. Is it possible to almost stream the download from the remote website - through my ASP.NET website directly to the user (a bit like a proxy) ? My current code is as follows: using (var client = new WebClientEx()) { client.DownloadFile(downloadURL, "outputfile.zip"); } WebClient class: public class WebClientEx : WebClient { public CookieContainer CookieContainer { get; private set; } public WebClientEx() { CookieContainer = new CookieContainer(); } protected override WebRequest GetWebRequest(Uri address) { var request = base.GetWebRequest(address); if (request is HttpWebRequest) { (request as HttpWebRequest).CookieContainer = CookieContainer; } return request; } }
