  • URL Slugs: Redirects or 404s?

    - by anonymous coward
    Some sites, like here at SO, allow 'bogus' slugs in the URL. Before implementing URL slugs on my site, I have a question of 'best practices'... Given a structure like example.com/123/article-slug-here/, if my site allows bogus slugs by querying on the ID - Should I ... just do a redirect to the appropriate/canonical URL (verifying the slug, and redirecting in case of a mismatch)? -or- return a 404, since technically example.com/123/this-article-s-u-x doesn't exist?

  • NHibernate criteria construction

    - by brianberns
    I am trying to recreate something like the following SQL using NHibernate criteria: select Range, count(*) from ( select case when ent.ID between 'A' and 'N' then 'A-M' else 'Other' end as Range from Subject ) tbl group by tbl.Range I am able to create the inner select as follows: session.CreateCriteria<Subject>() .SetProjection( Projections.Conditional( Expression.Between("Name", "A", "N"), Projections.Constant("A-N"), Projections.Constant("Other"))) .List(); However, I can't figure out how to pipe those results into a grouping by row count. Any suggestions? Thanks. -- Brian

  • JPA - How to truncate tables between unit tests

    - by Theo
    I want to cleanup the database after every test case without rolling back the transaction. I have tried DBUnit's DatabaseOperation.DELETE_ALL, but it does not work if a deletion violates a foreign key constraint. I know that I can disable foreign key checks, but that would also disable the checks for the tests (which I want to prevent). I'm using JUnit 4, JPA 2.0 (Eclipselink), and Derby's in-memory database. Any ideas? Thanks, Theo

  • QueryPerformanceCounter Not Working Properly on Amazon EC2 with Win Server 2008

    - by timeitquery
    Our application makes use of QueryPerformanceCounter to measure timings. When running it on Amazon EC2 instances we are noticing number that are out of whack. The symptoms look very similar to what has been reported with virtualized machines on HP proreliant servers, however all the articles state that this was not the case for Windows Server 2008. The articles recommended modifing the boot.ini to /USEPMTIMER - however, this seem to be missing from the documentation on bcdedit - which replaced boot.ini

  • Command line or library "compare tables" utility for SQL server with comprehensive diff output to a

    - by MicMit
    I can't find anything like that. Commercial or free ( XSQL Lite is suitable for my case and ) tools show diffs in grids with possibility to export to CSV. Also they generate sync SQL scripts when run from command line. What I need is an output as a comprehensive report ( XML , HTML ) suitable for parsing so that I would be able to show similar diff grid in my application ( updated old/new values for each column , added - all values for row , deleted - all values for row and etc... ) .

  • When creating an bitmap image from scratch in VB.Net, the quality stinks?

    - by ajl
    The Vb.Net application creates a bitmap from scratch and either converts to a tiff or sends it to a printer. In both cases, the quality of the image (in this case the font) is not good at all. The sample code listed below creates the graphics object that I use to write to the image. Dim gr2 As Graphics = Graphics.FromImage(New Bitmap(800, 1000), Imaging.PixelFormat.Format32bppPArgb))

  • jquery won't fade text if positioned: absolute;

    - by DA
    I have LI that I want to fade out and back in. Within the list item I have some text. This text is positioned absolutely within the LI. The catch is that in IE8 (IE6 and 7 seem fine) I can get everything to fade except the text: http://jsbin.com/esamu/13 If I remove the absolute positioning on the text element (in this case, a P), IE8 then can fade the text properly: http://jsbin.com/esamu/14 Anyone know why this is? Anyone know of a fix?

    I'm learning about static vs dynamic types, and I am to the point of understanding it for the most part, but this case still eludes me. If class B extends A, and I have: A x = new B(); Is the following allowed?: B y = x; Or is explicit casting required?: B y = (B)x; Thanks!

  • Django vs GAE + Django vs GAE + other framework

    - by Ilian Iliev
    I`m looking for opinion which one is better for building web applications(web sites). I have some experience with Django, and some with Google App Engine and App-Engine-Patch for Django. And it seems to me that only Django is working faster than the GAE implementation. Is there some other frameworks that simplify the developments process, providing forms creating, user management, url resolving etc. Thanks in advance, Ilian Iliev P.S. I am also interested in GAE and webapp framework case

  • Easiest way to automatically download required modules in Python?

    - by user248237
    I would like to release a python module I wrote which depends on several packages. What's the easiest way to make it so these packages are programmatically downloaded just in case they are not available on the system that's being run? Most of these modules should be available by easy_install or pip or something like that. I simply want to avoid having the user install each module separately. thanks.

  • How do I extend a python module? (python-twitter)

    - by user319045
    What are the best practices for extending a python module -- in this case I want to extend python-twitter by adding new methods to the base API class. I've looked at tweepy, and I like that as well, I just find python-twitter easier to understand and extend with the functionality I want. I have the methods written already, I'm just trying to figure out the best way to add them into the module, without changing the core.

  • table cell and row borders different on each edge in C#

    - by tbischel
    I'm trying to dynamically generate a report in a table where the borders are different on each side of a cell or row, but can't figure out how. The TableRow, TableCell, and Table objects each have a BorderStyle property, but it seems to apply to the entire border rather than just one side. Can this be done without nesting tables? For my case, I'd like a solid border around the first two rows of a table (because the first row has a cell spanning two rows), and a solid border around each subsequent row.
