• JQuery .load() function silently fails when offline

  - by edoloughlin

  I'm trying to write an iPhone offline webapp using jqtouch/jquery. When I disable my connectivity, it looks like the jquery .load() function silently fails and doesn't even call its callback function. I've set $.ajaxSetup ({cache: true}); but it seems to have no effect. I also have my manifest file etc. working fine - the only issue is the .load() function. Any ideas?

• Does OOP make sense for small scripts?

  - by Fabian

  I mostly write small scripts in python, about 50 - 250 lines of code. I usually don't use any objects, just straightforward procedural programming. I know OOP basics and I have used object in other programming languages before, but for small scripts I don't see how objects would improve them. But maybe that is just my limited experience with OOP. Am I missing something by not trying harder to use objects, or does OOP just not make a lot of sense for small scripts?

• Can I get Visual Studio to provide Intellisense and syntax coloring for Less Css ?

  - by driis

  I am experimenting with Less Css, and I am using Visual Studio 2010. It would be nice if the editor provided support for syntax highlighting and Intellisense for Less, for instance coloring and suggesting variables. What are my options to get that to work ? Do I need to write a plugin for it, or how would one go about adding this to VS ? Does anything exist for this already ?

  We need to write a script that needs to process movies (using C-based ffmpeg) and also update our databases. Also there would be some thread programming to accomplish with a worker-manager design.

• QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's

  - by Greg

  Hi, In QuickGraph - is there algorithm for find all parents (up to root vertex's) of a set of vertex's. In other words all vertex's which have somewhere under them (on the way to the leaf nodes) one or more of the vertexs input. So if the vertexs were Nodes, and the edges were a depends on relationship, find all nodes that would be impacted by a given set of nodes. If not how hard is it to write one's own algorithms?

• Deploying to Heroku with sensitive setting information

  - by TK

  I'm using GitHub for code and Heroku for the deployment platform for my rails app. I don't want to have sensitive data under Git. Such data include database file settings (database.yml) and some other files that have secret API keys. When I deploy to heroku, how can I deal with files that are not under revision control. When I use Capistrano, I can write some hook methods, but I don't know what to do with Heroku.

  - by jacobsee

  For a large application written in C++ using Visual Studio 6, what is the best way to move into the modern era? I'd like to take an incremental approach where we slowly move portions of the code and write new features into C# for example and compile that into a library or dll that can be referenced from the legacy application.

• C preprocessor: using #if inside #define?

  - by Wxy

  I want to write a macro that spits out code based on the boolean value of its parameter. So say DEF_CONST(true) should be expanded into "const", and DEF_CONST(false) should be expanded into nothing. Clearly the following doesn't work because we can't use another preprocessor inside #defines: #define DEF_CONST(b_const) \ #if (b_const) \ const \ #endif Any idea about how to do it?

• How to get multiple counts with one SQL query?

  - by Crobzilla

  I am wondering how to write this query. I know this actual syntax is bogus, but it will help you understand what I am wanting. I need it in this format, because it is part of a much bigger query. SELECT distributor_id, COUNT(*) AS TOTAL, COUNT(*) WHERE level = 'exec', COUNT(*) WHERE level = 'personal' I need this all returned in one query. Also, it need to be in one row, so the following won't work: 'SELECT distributor_id, COUNT(*) GROUP BY distributor_id'

• Delayed instantiation with c# using statment

  - by fearofawhackplanet

  Is there any way to write a using statement without instantiating the IDisposable immediately? For example, if I needed to do something like: using (MyThing thing) { if (_config == null) { thing = new MyThing(); } else { thing = new MyThing(_config); } // do some stuff } // end of 'using' Is there an accepted pattern for cases like this? Or am I back to handling the IDisposable explicitly again?

  I have a mysql database that stores quotation documents with some products that are clearly defining the price of each product in them, and a table for contracts storing contract details as well as customer code and quotation code to which it belongs.

• Conditional Join In LINQ?

  - by Soo

  I am trying to write a query that grabs information from one database and joins it to information in a different database. TableA idA valueA idB TableB idB valueB The tricky part is that in TableA, idB isn't always defined, so when I do a normal join, I only get results where TableA has a idB value. What I want is to be able to grab all of the information from TableA even if it doesn't have a corresponding idB value.

• SQL Server 2008 - Query takes forever to finish even though work is actually done

  - by Brian

  Running the following simple query in SSMS: UPDATE tblEntityAddress SET strPostCode= REPLACE(strPostCode,' ','') The update to the data (at least in memory) is complete in under a minute. I verified this by performing another query with transaction isolation level read uncommitted. The update query, however, continues to run for another 30 minutes. What is the issue here? Is this caused by a delay to write to disk? TIA
