• How does Fluent NHibernate manage to get a reference to a property using that weird delegates?

  - by André Pena

  For instance, if I want to map property Title I use: > Map(x => x.Title); That's weird because this delegate is only returning the value of the property and not the property itself while NHibernate needs to know the property itself. How does it work?

• Handling of data truncation in FUSE

  - by Vi

  I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not. Are them buggy or programs should not expect truncated writes and reads from the regular files?

• Rails: Why does find_by not work on my ActiveRecord model?

  - by randombits

  I have a simple model named Foo. Foo has two columns, bar and foobar. Doing a simple Foo.find_by_bar("a") is returning nil. There is a record in the table where bar contains a. Also, what's even more troubling, is I don't see the query even happening in the development log. A simple Foo.find(1) works though.

• How can I return a Dictionary from F# to C# without having to include FSharp.Core?

  - by Benjol

  I'm trying to return a IDictionary<int,int> (created with dict tuplist) from F# to C#, but it says that I must include a reference to FSharp.Core because of System.Collections.IStructuralEquatable. I've tried returning a Dictionary<_,_>(dict tuplist), but that doesn't make any difference. I even tried Dictionary<_,_>(dict tuplist, HashIdentity.Reference), but that says that int is a struct...

• How to with extract url from tweet using Regular Expressions

  - by neutreno

  Ok so i'm executing the following line of code in javascript RegExp('(http:\/\/t.co\/)[a-zA-Z0-9\-\.]{8}').exec(tcont); where tcont is equal to some string like 'Test tweet to http://t.co/GXmaUyNL' (the content of a tweet obtained by jquery). However it is returning, in the case above for example, 'http://t.co/GXmaUyNL,http://t.co/'. This is frustracting because I want the url without the bit on the end - after and including the comma. Any ideas why this is appearing? Thanks

• PHP problem with getimagesize()

  - by RobHardgood

  I'm using the getimagesize() function in PHP and it keeps returning an error: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory I'm not doing anything strange with it. The only problem I can imagine is that the path URL is another PHP script that returns a page with an image header, and there is an ampersand in that URL. Here is my code: $location = "image.php?name=username&pic=picture"; $size = getimagesize($location);

  I understand that for TCP sockets ECONNRESET has got something to do with RST packets. But I've seen ECONNRESET errors for AF_LOCAL sockets too, on read() and write() calls. What does this mean? How is ECONNRESET different from read() returning 0 or write() throwing EPIPE?

• Installing PHP DOM functions on Apache

  - by user352556

  I have just moved my code over to a new server (running on Apache 2.2.3), and PHP's DOM functions are now returning "Fatal error: Class 'DOMDocument' not found". I did some research and it appears that the installation I am now on does not have PHP's DOM functions enabled. I need to enable these functions, so what is the quickest way to go about this? Is it doable from a configuration file or will it require installation of extensions? Thanks!

  - by sumitchauhan

  I am using a data grid and has bound a data source with it. I am trying to get the total number of records in the grid in overriden InitializePager method from pagedDataSource DataSourceCount. I thought DataSourceCount returns number of records from SelectCountMethod of ObjectDataSource, but DataSourceCount is giving me the page size and not the total number of records, whereas when I debug and see in SelectCountMethod it is returning correct number of total Records. I am not sure how to get the data from SelectCountMethod in DataGrid.

• Any benefits of using Windows Communication Foundation/ Web Services vs. a simple .aspx page for s

  - by Clay Nichols

  I'm working on a VB6 app that will do some very simple communication with a web server (passing value and getting back an anwer. Low bandwith and infrequent use). Someone suggested using WCF or Web Services. I'm wondering what the advantages are vs. just posting to an ASPX page like: Myserver.com/Functions.ASP?FunctionName=GetValue?UserName=BubbGump and returning some simple, easy to parse text, like one value per line.
