  • Ruby and Forking

    - by Cory
    Quick question about Ruby forking - I ran across a bit of forking code in Resque earlier that was sexy as hell but tripped me up for a few. I'm hoping for someone to give me a little more detail about what's going on here. Specifically - it would appear that forking spawns a child (expected) and kicks it straight into the 'else' side of my condition (less expected. Is that expected behavior? A Ruby idiom? My IRB hack here: def fork return true if @cant_fork begin if Kernel.respond_to?(:fork) Kernel.fork else raise NotImplementedError end rescue NotImplementedError @cant_fork = true nil end end def do_something puts "Starting do_something" if foo = fork puts "we are forking from #{Process.pid}" Process.wait else puts "no need to fork, let's get to work: #{Process.pid} under #{Process.ppid}" puts "doing it" end end do_something

  • How to do a natural sort on an NSArray?

    - by Cory Imdieke
    I've got an array of objects, and I need them sorted by their "title" key. It's currently working, though it's using an ASCII sort instead of a natural sort. The titles are filenames, so they look like this: file1 file2 file3 ... file10 file11 file12 I'm getting, as you would expect: file1 file10 file11 file12 file2 file3 ... Does anyone know if there is a way built-in to the NSArray sorting functionality to get this natural sorting as opposed to the alphabetical sort? I found some generic algorithms, but I was hoping for something built-in...

  • SSIS: "Failure inserting into the read-only column <ColumnName>"

    - by Cory
    I have an Excel source going into an OLE DB destination. I'm inserting data into a view that has an INSTEAD OF trigger that handles all inserts. When I try to execute the package I receive this error: "Failure inserting into the read-only column ColumnName" What can I do to let SSIS know that this view is safe to insert into because there is an INSTEAD OF trigger that will handle the insert? EDIT (Additional info): Some more additional info. I have a flat file that is being inserted into a normalized database. My initial problem was how do I take a flat file and insert that data into multiple tables while keeping track of all the primary/foreign key relationships. My solution was to create a VIEW that mimicked the structure of the flat file and then create an INSTEAD OF trigger on that view. In my INSTEAD OF trigger I would handle the logic of maintaining all the relationships between tables My view looks something like this. CREATE VIEW ImportView AS SELECT CONVERT(varchar(100, NULL) AS CustomerName, CONVERT(varchar(100), NULL) AS Address1, CONVERT(varchar(100), NULL) AS Address2, CONVERT(varchar(100), NULL) AS City, CONVERT(char(2), NULL) AS State, CONVERT(varchar(250), NULL) AS ItemOrdered, CONVERT(int, NULL) AS QuantityOrdered ... I will never need to select from this view, I only use it to insert data into it from this flat file I receive. I need someway to tell SQL Server that the fields aren't really read only because there is an INSTEAD OF trigger on this view.

  • How to get or own your own IP address?

    - by Cory
    The website we running let people register their own URL and redirect to our website to their user account. Lets it is something similar to Blogspot.com where users can have their own URL. The problem is that in order to do this we need to have static IP address for the DNS redirection to work. We can easily get static IP addresses from most hosting companies, but if we change our hosting company it means we will have to force all our users to change their DNS setting to our new IP address. This if very problematic. Is there a way of owning our own IP address that we can take it with us to wherever hosting company we decide to go with? Or there there other easier solutions out there?

  • How do you set rate limit access to your API using Iptables?

    - by Cory
    How can you set rate limit access to API using Iptables. Tried to set limit using port 80, but I don't want to set limit to the web access entirely. Is there a way to specified a subdomain rather than port. Example: set rate limit to api.example.com not example.com? If there is no way to set rate limit by subdomain, what is the suggested rate limit access to port 80 without risking blocking a legitimate web user? One connection per second would be enough?

  • Migrate style from TabItem to TabHeader

    - by OffApps Cory
    Good day! I have a TabControl with TabItems that have been customized via a control template. This control template specifies a trigger whereby on mouseover, the content of tab header grows slightly. <ControlTemplate> <Storyboard x:Key="TabHeaderGrow"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="TabName" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.1000000" Value="1.1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="TabName" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)"> <SplineDoubleKeyFrame KeyTime="00:00:00.1000000" Value="1.1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <ControlTemplate.Triggers> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <BeginStoryboard Storyboard="{StaticResource TabHeaderGrow}"/> </EventTrigger> When I mouseover any of the tabs they work as expected, however the trigger also fires when I mouseover any of the elements in the tab body. I know that I need to migrate the control styling to a tabHeader controlTemplate, but I am unsure how to do that. I can't seem to do template binding for the content of the tabheader. Any help would be appreciated.

  • Sphinx autodoc is not automatic enough

    - by Cory Walker
    I'm trying to use Sphinx to document a 5,000+ line project in Python. It has about 7 base modules. As far as I know, In order to use autodoc I need to write code like this for each file in my project: .. automodule:: mods.set.tests :members: :show-inheritance: This is way too tedious because I have many files. It would be much easier if I could just specify that I wanted the 'mods' module to be documented. Sphinx could then recursively go through the module and make a page for each submodule. Is there A feature like this? If not I could write a script to make all the .rst files, but that would take up a lot of time.

  • MySQL triggers cannot update rows in same table the trigger is assigned to. Suggested workaround?

    - by Cory House
    MySQL doesn't currently support updating rows in the same table the trigger is assigned to since the call could become recursive. Does anyone have suggestions on a good workaround/alternative? Right now my plan is to call a stored procedure that performs the logic I really wanted in a trigger, but I'd love to hear how others have gotten around this limitation. Edit: A little more background as requested. I have a table that stores product attribute assignments. When a new parent product record is inserted, I'd like the trigger to perform a corresponding insert in the same table for each child record. This denormalization is necessary for performance. MySQL doesn't support this and throws: Can't update table 'mytable' in stored function/trigger because it is already used by statement which invoked this stored function/trigger. A long discussion on the issue on the MySQL forums basically lead to: Use a stored proc, which is what I went with for now. Thanks in advance!

  • Troubleshooting MSSQL Connection from PHP

    - by Cory Dee
    I'm trying to connect to an external Sql Server through PHP 5.2. Using this line: $con = mssql_connect('123.123.123.123','Username','Password') or die('Could not connect to the server!'); I'm receiving this error: Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: 123.123.123.123 in /home/file/public_html/structure/index.php on line 4 Could not connect to the server! My hosting provider assures me that ports are open for my server to connect to the DB. Looking at my php info, MSSQL Support is enabled, using FreeTDS. Any ideas why this would be failing, or how I can begin trouble shooting the problem?

  • How to properly use Object Contexts in Entity Framework using BackgroundWorker

    - by OffApps Cory
    Good day, I am developing using Entity Framework and WPF, and I am encountering some errors and I don't know why. When saving a record (using a BackgroundWorker), I set the entities change tracker to nothing (null), attach the record to a new disposable context, save it, detach, and dispose of the context. Saving a record fires and event in the MainViewModel of the program that the other ViewModels (including the one that is saving) need to refresh their entities to reflect changes. Private Sub _saveRecordWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles _saveRecordWorker.DoWork Using MyContext As New RVShippingEntities Dim MyShipment = CType(ShipmentRecord, IEntityWithChangeTracker) MyShipment.SetChangeTracker(Nothing) MyContext.Attach(MyShipment) MyContext.Detach(ShipmentRecord) End Using End Sub The Refresh background worker is similar, but it has a Do While block to keep it from interfering with the save worker (which doesn't appear to be working; hence the post). When I save (and it subsequently refreshes) I get the following error: The calling thread cannot access this object because a different thread owns it. I thought that with the DoWhile block, it would wait (and when i step through it does) until the save thread finished, and all would be good. But it would seem that something (either the main thread or the save thread) is still doing something that is interfering. Is there a better way of doing this? Am I doing it is a goofy kludgey fashion? Any help would be appreciated. (Apparently Firefox recognized kludgey as a word. Interesting)

  • CouchDB Versioning / Auditing

    - by Cory
    I'm attempting to use CouchDB for a system that requires full auditing of all data operations. Because of its built in revision-tracking, couch seemed like an ideal choice. But then I read in the O'Reilly textbook that "CouchDB does not guarantee that older versions are kept around." I can't seem to find much more documentation on this point, or how couch deals with its revision-tracking internally. Is there any way to configure couch either on a per-database, or per-document level to keep all versions around forever? If so, how?

  • I'm looking for a reliable way to verify T-SQL stored procedures. Anybody got one?

    - by Cory Larson
    Hi all-- We're upgrading from SQL Server 2005 to 2008. Almost every database in the 2005 instance is set to 2000 compatibility mode, but we're jumping to 2008. Our testing is complete, but what we've learned is that we need to get faster at it. I've discovered some stored procedures that either SELECT data from missing tables or try to ORDER BY columns that don't exist. Wrapping the SQL to create the procedures in SET PARSEONLY ON and trapping errors in a try/catch only catches the invalid columns in the ORDER BYs. It does not find the error with the procedure selecting data from the missing table. SSMS 2008's intellisense, however, DOES find the issue, but I can still go ahead and successfully run the ALTER script for the procedure without it complaining. So, why can I even get away with creating a procedure that fails when it runs? Are there any tools out there that can do better than what I've tried? The first tool I found wasn't very useful: DbValidator from CodeProject, but it finds fewer problems than this script I found on SqlServerCentral, which found the invalid column references. ------------------------------------------------------------------------- -- Check Syntax of Database Objects -- Copyrighted work. Free to use as a tool to check your own code or in -- any software not sold.

  • Effective books for learning the intricacies of business application development?

    - by OffApps Cory
    I am a self taught "developer". I use the term loosely because I only know enough to make myself dangerous. I have no theory background, and I only pick up things to get this little tool to work or make that control do what I want. That said, I am looking for some reading material that explains some of the theory behind application development especially from a business standpoint. Really I need to understand what all of these terms that float around really talk about. Business Logic Layer, UI abstraction level and all that. Anyone got a reading list that they feel helped them understand this stuff? I know how to code stuff up so that it works. It is not pretty mostly because I don't know the elegant way of doing it, and it is not planned out very well (I also don't know how to plan an application). Any help would be appreciated. I have read a number of books on what I thought was the subject, but they all seem to rehash basic coding and what-not. This doesn't have to be specific to VB.NET or WPF (or Entity Framework) but anything with those items would be quite helpful.

  • How can I use Three20 to create a dynamic TTThumbsViewController that feeds from a website directory?

    - by Cory Robbins
    Hello, I'm pretty new to the iPhone developing scene, and I am designing an app for a high school band program. Part of the app needs to be an image gallery that retrieves photos from a directory on the band's website and lists them in the thumbnail view. I can't figure out how to create a thumsview that isn't directly linked to specific pictures. I currently have this setup to work with a UIWebView that points to a PHP photo album designed to look like the iPhone Photo Album. This method works, but it is not ideal, and the navigation is obviously a bit less than what would be expected. Is Three20 the right tool for this job? If not, what should I be using? Thanks!

  • What reasons are there to place member functions before member variables or vice/versa?

    - by Cory Klein
    Given a class, what reasoning is there for either of the two following code styles? Style A: class Foo { private: doWork(); int bar; } Style B: class Foo { private: int bar; doWork(); } For me, they are a tie. I like Style A because the member variables feel more fine-grained, and thus would appear past the more general member functions. However, I also like Style B, because the member variables seem to determine, in a OOP-style way, what the class is representing. Are there other things worth considering when choosing between these two styles?

  • Dynamically adjust padding on an image?

    - by Cory
    What I'm basically attempting to do is dynamically change a padding value for a scrubber image based on player position data provided by an app. I have been able to leverage the provided number to dynamically increase the width of a progress overlay image and create a progress bar, but I would like a scrubber diamond at the leading edge of the progress bar. To do this, I have positioned the scrubber diamond at the same starting point as the progress overlay and would like to increase the padding on the diamond at the same rate as the width is increasing for the progress overlay, allowing them to pace each other with the scrubber diamond moving as the song plays. Any help with the script necessary to manipulate padding-left dynamically would be very much appreciated. var progress = Ecoute.playerPosition(); var width = 142.5 / length * progress + 1.63; EcouteSel('Progression').width = width.toString(); EcouteSel('Scrubber').style('padding-left', 'width'); We define progress as the player position, width as a function of the progress and then apply that function to the ID applied to the progress over lay image. But how do I accomplish that for padding-left? style.paddingLeft ...based functions have broken the controller outright. I'm at a loss and any help would be appreciated.
