• How do I use Declarations (type, inline, optimize) in Scheme?

  - by kunjaan

  How do I declare the types of the parameters in order to circumvent type checking? How do I optimize the speed to tell the compiler to run the function as fast as possible like (optimize speed (safety 0))? How do I make an inline function in Scheme? How do I use an unboxed representation of a data object? And finally are any of these important or necessary? Can I depend on my compiler to make these optimizations? thanks, kunjaan.

• ASP.NET MVC / Linq-to-SQL classes: Can I get it to infer readable display names?

  - by Gary McGill

  If I have a table Orders with fields CustomerID, OrderID and OrderDate, then the "Linq-to-SQL classes" generated class will be called Orders, with members called CustomerID, OrderID and OrderDate. So far so good. However, if I then do Html.LabelFor(m => m.OrderDate) then the generated text will be "OrderDate" instead of "Order Date". I tried using Order_Date as the field name, but that didn't work. Is there any way to get it to infer a better display name? [I know that I can use data annotations to specify the display name explicitly, but I really don't want to do that for all my classes/members - I just want it to work by convention.]

• Elegant PostgreSQL Group by for Ruby on Rails / ActiveRecord

  - by digitalfrost

  Trying to retrieve an array of ActiveRecord Objects grouped by date with PostgreSQL. More specifically I'm trying to translate the following MySQL querry: @posts = Post.all(:group => "date(date)", :conditions => ["location_id = ? and published = ?", @location.id, true], :order => "created_at DESC") I am aware that PostgreSQL interpretation of the SQL standard is stricter than MySQL and that consequently this type of query won't work...and have read a number of posts on StackOverflow and elsewhere on the subject - but none of them seem to be the definitive answer on this subject I've tried various combinations of queries with group by and distinct clauses without much joy - and for the moment I have a rather inelegant hack which although works makes me blush when I look at it. What is the proper way to make such a querry with Rails and PostgreSQL ? (Ignoring the fact that surely this should be abstracted away at the ActiveRecord Level)

• C# - How to implement multiple comparers for an IComparable<T> class?

  - by Gary Willoughby

  I have a class that implements IComparable. public class MyClass : IComparable<MyClass> { public int CompareTo(MyClass c) { return this.whatever.CompareTo(c.whatever); } etc.. } I then can call the sort method of a generic list of my class List<MyClass> c = new List<MyClass>(); //Add stuff, etc. c.Sort(); and have the list sorted according to my comparer. How do i specify further comparers to sort my collection different ways according to the other properties of MyClass in order to let users sort my collection in a number of different ways?

• Can the Sequence of RecordSets in a Multiple RecordSet ADO.Net resultset be determined, controlled?

  - by Shiva

  I am using code similar to this Support / KB article to return multiple recordsets to my C# program. But I don't want C# code to be dependant on the physical sequence of the recordsets returned, in order to do it's job. So my question is, "Is there a way to determine which set of records from a multiplerecordset resultset am I currently processing?" I know I could probably decipher this indirectly by looking for a unique column name or something per resultset, but I think/hope there is a better way. P.S. I am using Visual Studio 2008 Pro & SQL Server 2008 Express Edition.

• What is the best way to read files in an EventMachine-based app?

  - by Theo

  In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitely is). Open the file for reading and read a chunk on each tick (but how much to read? too much and it'll block the reactor, too little and reading will get slower than necessary). EM.popen('cat some/file', FileReader) feels really weird, but works better than the alternatives above. In combination with the LineAndTextProtocol it reads lines pretty swiftly. EM.attach, but I haven't found any examples of how to use it, and the only thing I've found on the mailing list is that it's deprecated in favour of… EM.watch, which I've found no examples of how to use for reading files. How do you read files within a EventMachine reactor loop?

• set up way of getting mysite.$domain

  - by jose silva

  Hi I have several domains, only one website and one databse table for each domain. example: wbesite.us - data from USA goes to database table main_usa wbesite.co.uk - data form UK goes to database table main_uk Only have one database with name of the website. Having only one website structured, and having variables like $sql="select * from main_".$countrycode." where bla..bla..., and many other variables to catch the domain extension, and so on... Now, instead of having one full website for each domain, how can set a script and wher do I put it in order to detect the domain that the user uses. In my server root do I create something like website.$domain ? Something like website OLX but for different purposes. I hope I made myself clear. Thank you.

• How might I escape Unicode characters in a JSON string using JavaScript?

  - by user293006

  JSON String: { "id":31896, "name":"Zickey attitude - McKinley, La Rosi\u00e8re, 21 ao\u00fbt 2006", ... } this causes an unterminated string in JavaScript. My attempt at a solution is: data.replace(/(\S)\1(\1)+/g, ''); or data.replace(/\\u([0-9A-Z])/, ''); any ideas/solution? Example: http://api.jamendo.com/get2/id+name+url+stream+album_name+album_url+album_id+artist_id+artist_name/track/jsonpretty/track_album+album_artist/?n=13&order=ratingmonth_desc&tag_idstr=jazz last node is the problem, fyi. (/\\u([0-9A-Z])/, '\1');

• Javascript eval limits

  - by user117701

  Is there a limit to javascript's eval, like in lenght? I'm trying to build an app where you can store JS code in the DB, which you can later load and eval in order to execute it, but i'm reaching a limit. First of all, the code has to all be in one line. Any multiline statements are not executed. Next, i'm reaching a limit in length (i guess). If i execute the code manually, it works, but put that same code in the db, load it via ajax, and try to execute it, and it fails. Any ideas why?

• mySQL php query - news/ friends feed

  - by rpsep2

  I want to show a user the recent uploads from their friends. I have the users friends id's in an array: $friends A user could have, potentially, thousands of friends. I can select the uploads from 1 of a users friends with: $row = $mysqli->query("SELECT * FROM photos WHERE uploader_id = ".$friend." ORDER BY date_uploaded DESC LIMIT ".$page.", 25"); But I need to find all of a users friends uploads. I thought about doing this in a loop iterating over the $friends array, but then I'd be potentially running thousands of mysql queries. How can I do this most efficiently? so to clarify: search a 'photos' table for photos which are uploaded by specific users(friends), held in $friends variable, sort by date_uploaded and limit to x results so I can have pages 1, 2, 3 etc.

• How can I implement lazy loading on a page with 500+ images?

  - by Fedor

  I basically have a booking engine unit results page which must show 40 units and per each unit there's 1 large image of the first thumbnail and an X number of accompanying thumbnail images. I've been using the jquery lazy load plugin, but it's not thorough enough ( I'm invoking it on DOM Ready ), plus it doesn't really work in IE ( 50% of the clients use IE so it's a big issue ). What I think I really need to do is not really spit out the image but a fake element such as a span, and possibly modify my code such that if the user views the span, render it into an image element. <span src="/images/foo.gif"> The booking engine relies on JS so I think I might be forced to just rely on ajaxifying all the thumbnails and have event handlers on window scroll, etc in order for the page to be "usable" and load at an average time ( 2-3 seconds instead of 5-30s on high speed DSL/Cable ). I'd appreciate any examples or ideas.

• Are C++ Reads and Writes of an int atomic

  - by theschmitzer

  I have two threads, one updating an int and one reading it. This value is a statistic where the order of the read and write is irrelevant. My question is, do I need to synchronize access to this multi-byte value anyway? Or, put another way, can part of the write be complete and get interrupted, and then the read happen. For example, think of value = ox0000FFFF increment value to 0x00010000 Is there a time where the value looks like 0x0001FFFF that I should be worried about? Certainly the larger the type, the more possible something like this is I've always synchronized these types of accesses, but was curious what the community thought.

• Best way to implement nested loops in a view in asp.net mvc 2

  - by Junior Ewing

  Hi, Trying to implement some nested loops that are spitting out good old nested html table data. So the question is; What is the best way to loop through lists and nested lists in order to produce easily maintainable code. It can get quite narly quite fast when working with multiple nested tables or lists. Should I make use of a HTML helper, or make something with the ViewModel to simplify this? A requirement is if there are no children at a node there should be an empty row on that spot with some links for creation and into other parts of the system.

• Paginating with SQL ROW_NUMBER

  - by Kelsey Thorpe

  I want to return search results in paginated format. However I can't seem to successfully get the first 10 results of my query. The problem is the 'RowNum' returned are like 405, 687, 1024 etc. I want them to be renumbered as 1,2,3,4,5 etc., so that when I specify between rows 1 and 20 i get the first 20 search results. Instead, because the numbers are larger, I get no results between 1 and 10. If i change RowNum condition to: AND RowNum < 20000 I get plenty of results Here's the sql: SELECT * FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY DocumentID ) AS RowNum, * FROM Table ) AS RowConstrainedResult WHERE RowNum >= 1 AND RowNum < 20 AND Title LIKE '%diabetes%' AND Title LIKE '%risk%' Any help appreciated.

• How do I (or should I?) access the service layer from a SiteMesh template (views/layouts/main.gsp) in Grails?

  - by knorv

  I need to create a toplist in the page footer on a site that I'm building. The footer is created in the default SiteMesh layout template (views/layouts/main.gsp). In order to create the toplist access to the database is needed, so I've encapsulated all logic needed for the toplist creation in a service class (services/FooService). Please note that while services are usually accessed from the controller layer, in this case the default layout template (views/layouts/main.gsp) is not generated from a controller. Can the layout view (views/layouts/main.gsp) access a service class? How? Is this the correct design decision? If not, what is a better encapsulation and how do I interact with said encapsulation from the layout view (views/layouts/main.gsp)?

• How we run a .NET 32-bit application in a 64-bit Windows server?

  - by Geo

  We are installing a third party application in one of our 64-bit Windows servers. This application apparently was build with the compiler option set to choose the platform at run time. When we run the application it gives us an error: System.BadImageFormatException: is not a valid Win32 application. I have seen in MSDN forums that in order to fix this error I have to build the application set to 32-bit, and that way it will run fine on a 64-bit server. I check on other StackOverflow links Other Posts. How to get around this situation? For everyone that wants to know more information: The application is running fine in a 32-bit test server. IIS version 6 using SQL Server Express 2005 On the Web Service Extension there are both Framework64\v2.0.50727\aspnet_isapi.dll and Framework\v2.0.50727\aspnet_isapi.dll

• Code Golf: All +-*/ Combinations for 3 integers

  - by Flash84x

  Write a program that takes 3 integers separated by spaces and perform every single combination of addition, subtraction, multiplication and division operations possible and display the result with the operation combination used. Example: $./solution 1 2 3 Results in the following output 1+2+3 = 6 1-2-3 = -4 1*2*3 = 6 1/2/3 = 0 (integer answers only, round up at .5) 1*2-3 = -1 3*1+2 = 5 etc... Order of operation rules apply, assume there will be no parenthesis used i.e. (3-1)*2 = 4 is not a combination, although you could implement this for "extra credit" For results where a divide by 0 occurs simply return NaN

• Developing and deploying games for Windows, Mac (& Linux)

  - by nornagon

  I want to write games that run on all the major platforms. I also want people to be able to play them by downloading a file and double clicking it. That means a single .exe/.app file. I'm happy to use OpenGL directly for graphics. What I don't know how to do is show a window, handle mouse/keyboard input and play sounds in a cross-platform manner. I don't really mind what the underlying language is, as long as it isn't C++ or Java. C#, Ruby or Python would be preferable, in that order :) Please, SO, save me from having to write Flash games!

• Converting one alphabet to another

  - by Branimir

  I am preparing a simple dictionary project and I have prepared it to search in 2 languages. Still, as one of them is using Cyrillic letters, I have to be able to check in the database, even if the word is written in Latin letters. What do I mean in Cyrillic: ??? in Latin: kon Both should give the description of the word (in this case "horse"). I have been thinking of using two structures with two alphabets in order to achieve this....Still somehow I cannot get it. Does some of you have experience in a similar situation? If yes - please share an advice or code-sample.

• Jquery check if element exists then add class to different element

  - by Buddy

  I don't know much about jquery at all, so bear with my ignorance, but I'm pretty sure I can accomplish this with jquery. I need jquery to check if an element exists, and if so, add a class to a different element. For example, if class "minimal-price-link" exists, then add a class to "regular-price" or what I really am wanting to do is make the regular-price strikethrough. Here's the code: <div class="price-box"> <span class="regular-price" id="product-price-2"> <span class="price">$240.00</span> </span> <a href="http://stemulation.com/order/sfs30.html" class="minimal-price-link"> <span class="label">Your Price:</span> <span class="price" id="product-minimal-price-2">$110.00</span> </a> </div>

• How can I get the edit control in a cell of a DataGridView to validate itself?

  - by Stuart Helwig

  It appears that the only way to capture the keypress events within a cell of a DataGridView control, in order to validate user input as they type, is to us the DataGridView controls OnEditControlShowing event, hook up a method to the edit control's (e.Control) keypress event and do some validation. My problem is that I've built a heap of custom DataGridView column classes, with their own custom cell types. These cells have their own custom edit controls (things like DateTimePickers, and Numeric or Currency textboxes.) I want to do some numeric validation for those cells that have Numeric of Currency Textboxes as their edit controls but not all the other cell types. How can I determine, within the DataGridView's "OnEditControlShowing" override, whether or not a particular edit control needs some numeric validation? (In the meantime I've restorted to setting the Tag property of my custom edit controls to a known value and any Edit Controls I find in the OnEditControlShowing override, I hook to my validation routine - I don't like that much!)
