• In Ruby on Rails Routing I Would Like to Use Dash `-` Instead of Underscore `_`

  - by pablitostar

  I would like all the URLs for my web applications to use dash - instead of underscore _ for word separators. I'm surprised about a couple of things really: Google et al. continue to distinguish them. That RoR doesn't have a simple global configuration parameter to map - to _ in the routing. Or does it? I found a few questions here and elsewhere, but the best solution I've seen is to use :as or a named route. That's quite annoying. So I'm thinking of modifying the Rails routing to check for that global config and change - to _ before dispatching to a controller action. But before I do that, I'm hoping someone can save me the trouble! Thanks in advance for any help, or even confirmation that my approach makes sense. I'd submit it back. BTW, I'm currently on 2.3.8, but hope to migrate to 3 soon.

• Android playing Video data from a custom network stream?

  - by Cinar

  Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

• Regular expression help parsing SQLIO output

  - by jaspernygaard

  Hi I've been working on a regular expression to parse the output of a series of SQLIO runs. I've gotten pretty far, but not quite there yet. I'm seeking a 100% regex solution and no pre-manipulation of the input. Could anyone assist with a little guidance with the following regular expression: .*v(?<SQLIOVersion>\d\.\d).*\n.*\n(?<threads>\d*)\s.*for\s(?<Seconds>\d+).*\n.*using\s(?<clustersize>[0-9]*)KB.*\n.*\n.*size:\s(?<currentfilesize>\d+).*\n.*\n.*\n.*\n.*\s(?<IOs>\d*\.\d*).*\n.*\s(?<MBs>\d*\.\d*).*\n.*\n.*\s(?<MinLatency_ms>\d+).*\n.*\s(?<AvgLatency_ms>\d+).*\n.*\s(?<MaxLatency_ms>\d+).*\n.*\n.*\n\%\:..(?<ms>\d*\s+)* Here's a snippet of the output - note the headers, which change during the SQLIO batch run: File

• Global Import Aliasing in .NET

  - by Josh Stodola

  Using import aliasing in a single class, we can reference class library namespaces by assigning our own custom alias like this: Imports Db = Company.Lib.Data.Objects And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned. Is it possible to do this at the global level so that the alias is applied to the entire solution instead of the given file? Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

• How to tell if running in a linux console versus an ssh session?

  - by Stéphane

  I have an application that needs to behave differently if run directly from the linux console. So if a user connects with SSH to run FooBar, or the user walks over to the console and logs in directly to run FooBar, I want it to do something different. What C API do I need to call to tell the difference between these two scenarios? I was thinking I'd have to look at the "tty/pts" information (such as what I see when I run "ps axf"), but I'm not certain if that is the best solution, nor what API to call to get that information. Hints appreciated. :)

• How can I test whether a csv file is currently open and being written to - the file, not a file hand

  - by Henry

  I've seen a few questions/answers here that deal with this, but none really give me an answer/solution. I've got a Clipper system writing csv files to a Windows directory. I have a perl script running on a Linux server that is reading a mount of that Windows directory and importing the files to a database. Right now we're using flag files to indicate when a csv is no longer being written to; the flag files gets written after the csv is done. I'd really rather just get what I need from the csv itself, but I can't seem to find a way to tell when the file is open and being written to. lsof doesn't seem to answer my need. I've tried using flock and open the file with an exclusive lock, thinking it might throw an error if the file is being modified, but it doesn't. Any thoughts?

• ASP.NET URL Re-writing; Is this possible?

  - by James Evans

  My app is currently written to accept vendor and product information like this. http://www.mydomain.com/foo.aspx?v=1&p=100 could this be re-written like this? http://www.mydomain.com/1/100/foo Since the values in the original query string are database IDs, how would I express newly created IDs as segments of the "path" in the re-written version of the URL? My goal would be to create more of an automated solution that would accomplish this. EDIT: The app is written using ASP.NET webforms, .NET 4.0 and IIS 7

• Allowing AsyncTask to Manipulate Values in Different Activity Classes

  - by Matt

  Hi guys, This title may seem strange, so let me try to explain what I'm trying to do. I have several activity classes, each representing a different view in my application. My initial activity class gets loaded when the application launches. The user enters values and eventually a TCP socket is opened, and I then use AsyncTask to listen for and respond to messages from the server. I'd like for this AsyncTask class to essentially listen until the app is closed/error condition reached, and be able to update values in other activity classes after they are started. Does this make sense (it's been a long, frustrating night)? I know that static activity class references are bad practice, and touching the UI thread from other activities is bad as well, but I'm having trouble finding a clean solution to this problem. Maybe using AsyncTask is not the best approach here? Should I be using a service instead or something else entirely? Thanks in advance.

• emacs list-buffers behavior

  - by Stephen

  In GNU emacs, every time I hit Ctrl-x Ctrl-b to see all of my buffers, the window is split to show the buffer list, or if I have my window already split in 2 (for instance, I will have a shell running in the lower window), the buffer list appears in the other window. My desired behavior is for the buffer list to appear in my active window so that I can select the buffer I want and continue to working in the same window, rather than having to Ctrl-x Ctrl-o to the other buffer, selecting the buffer (with enter) and editing that buffer in the other window... I've googled for it but it doesn't seem to be a common desire? I wonder if anyone has an elispy (or other) solution?

• How to copy value from class X to class Y with the same property name in c#?

  - by Samnang

  Suppose I have two classes: public class Student { public int Id {get; set;} public string Name {get; set;} public IList<Course> Courses{ get; set;} } public class StudentDTO { public int Id {get; set;} public string Name {get; set;} public IList<CourseDTO> Courses{ get; set;} } I would like to copy value from Student class to StudentDTO class: var student = new Student(); StudentDTO studentDTO = student; How can I do that by reflection or other solution?

• How to vertically align an inline image with inline text following it?

  - by amn

  Is there any way to vertically align an image element generated by a "content" property as part of a ":before" selector, next to adjacent inline text? In other words, I have <a href="..." class="facebook">Share on Facebook</a> As I don't want to pollute my markup with unnecessary IMG elements that only have to do with style, I resort to adding a small icon to the left of the link, via CSS (except that it does not align properly, hence the question): a.facebook:before { content: url(/style/facebook-logo.png); } I tried adding a "vertical-align: middle" (one of the most notoriously difficult aligning concepts to grasp in CSS, in my opinion, is that very property) but it has no effect. The logo aligns with text baseline, and I don't want to hardcode pixel offsets, because frankly text size differs from browser to browser, etc. Is there any solution for this? Thanks.

• Django, javascript and code ruse problem

  - by dragoon

  Hi, I have some sort of a design problem with my Django AJAX application. I have a template where I initialize js variable from django context variable like so: var test = "{{ test }}"; This variable is than used in a number of js functions that are needed for interface to work properly. So now I'm trying to reuse some content from this page in another page that loads it dynamically on some user interaction using jQuery.load(..), and I don't see any way how I can initialize that variable, so js functions don't work now. Is there any solution for this or may be I'm doing it wrong? Thanks.

• C# - Copy dlls to the exe output directory when using dependency injection with no references?

  - by NotDan

  I have a C# solution that I am using dependency injection to resolve references between dlls. I have an exe project and some other dll projects that are not referenced by the exe (It uses the dlls through the IoC container). The project settings are the default, visual studio settings where it builds each dll in it's own folder. Since the exe doesn't reference the dlls, they never get copied to the output directory of the exe and don't get found by the IoC framework. How do you handle this? Do you build them all in the same directory? Use post build copy commands? Or something else?

• How to convert .NET WPF application to Windows Forms?

  - by Janusz

  Hello, We have created a beautifully designed .NET WPF desktop application. We are installing the application with InnoSetup , and if .NET 3.5 is not present, it automatically installs it. However, the package to download .NET 3.5 is huge and we found out that about 30% of users do not finish instalation due to this. The obvious solution is to recode everything into .NET 1.1 with Windows Forms but its a major development which would take few weeks. Also, we would then face dilemma if to support both versions (and use innosetup to choose the right one) or just ditch WPF all together. Is there any easy way how to convert WPF to Windows Forms? Or do we have any alternative options to consider? Thank you!

• Getting fields of a class through reflection

  - by Water Cooler v2

  I've done it a gazillion times in the past and successfully so. This time, I'm suffering from lapses of amnesia. So, I am just trying to get the fields on an object. It is an embarrassingly simple and stupid piece of code that I am writing in a test solution before I do something really useful in production code. Strangely, the GetFieldsOf method reports a zero length array on the "Amazing" class. Help. class Amazing { private NameValueCollection _nvc; protected NameValueCollection _myDict; } private static FieldInfo[] GetFieldsOf(string className, string nameSpace = "SomeReflection") { Type t; return (t = Assembly.GetExecutingAssembly().GetType( string.Format("{0}.{1}", nameSpace, className) )) == null ? null : t.GetFields(); }

• Rollback to a specific moment with PostgreSQL

  - by mada54

  Hi, Is there a way to rollback to a specific starting point. Im looking for something like this. Start specific_point; Now after this, an other application connected with the SAME login will insert & delete datas (webservices with crud operations) for about 2 minutes doing tests. Each webservice call is declared as a transaction with Spring Ws. After that i want to rollback to the specific_point to have a clean database to a known previous state. I was thinking that ROLLBACK TO SAVEPOINT foo; was the solution but not unfortunately? Any idea ? Configuration: PostgreSQL 8.4 / windows XP Regards

• Add function to existing JQuery plugin

  - by kralco626

  Is it possible to add a function to a plugin without modifying the actual plugin? Can I do something like this in my site's js file? $.fn.Watermark.Refresh = function() { $.Watermark.HideAll(); $.Watermark.ShowAll(); } or (function($){ $.fn.Watermark.Refresh = function() { $.Watermark.HideAll(); $.Watermark.ShowAll(); }; })(jQuery); neither worked, the first says $ is undefined, the second that jQuery is undefined... ideas? Solution: Either method works, just include the jquery file before the site js file.

• Can I detect unused extra parameters passed to javascript methods?

  - by Pablojim

  In Javascript I can call any method with more than the necessary amount of parameters and the extra parameters are silently ignored. e.g. letters = ['a','b','c'] //correct letters.indexOf('a') //This also works without error or warning letters.indexOf('a', "blah", "ignore me", 38) Are there ways to detect cases where this occurs? My motivation is that in my experience cases where this occurs are usually bugs. Identification of these by code analysis or at runtime would help track these errors down. These cases are especially prevalent where people are expecting alterations to base types which may not have occurred. Logging a warning where this happens e.g. Date.parse('02--12--2012', 'dd--MM--YYYY') Notes: To be clear I would like a solution that doesn't involve me sprinkling checks all over my code and other peoples' code.

• CSS Containers and Framing

  - by CaffeineAddiction

  I am attempting to code a dynamic object for use in an unordered list. I have a mock up of the HTML here: <ul class='Main'> <li class='Node'> <span class='Node_Light'> </span> <span class='Node_Control'> <span class='Ctrl_Name'> <span class='CtrlN_Text'>Random Name</span> <span class='CtrlN_Edit'>[%]</span> </span><br/> <span class='Ctrl_ID'>ff:ff:ff:ff:ff:ff</span><br/> <span class='Ctrl_Buttons'> <span class='CBttn_On'>[%]</span> <span class='CBttn_Off'>[%]</span> <span class='CBttn_Blink'>[%]</span> <span class='CBttn_Config'>[%]</span> <span class='CBttn_Graph'>[%]</span> </span> </span> <span class='Node_Data'> <span class='ND_Sens0'> <span class='Sens_Lable'>temp:</span> <span class='Sens_Data'>72</span> <span class='Sens_Units'>&#176;F</span> </span><br/> <span class='ND_Sens1'> <span class='Sens_Lable'>Sens1:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span><br/> <span class='ND_Sens2'> <span class='Sens_Lable'>Sens2:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span><br/> <span class='ND_Sens3'> <span class='Sens_Lable'>Sens3:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span><br/> <span class='ND_Sens4'> <span class='Sens_Lable'>Sens4:</span> <span class='Sens_Data'>Off</span> <span class='Sens_Units'></span> </span> </span> </li> </ul> and I am attempting to wrangle this HTML into something like: My first problem was that the 3x Outer elements would stack vertically instead of horizontally ... I solved this with the following CSS, but it doesnt feel like the right solution: ul { list-style-type: none; padding:0; margin:0; } .Node { } .Node_Light { height:6em; width:2em; position:absolute; border-style:solid; border-width:1px; } .Node_Control { height:6em; width:15em; position:absolute; left:2.55em; border-style:solid; border-width:1px; } .Node_Data { height:6em; width:6em; position:absolute; left:17.6em; border-style:solid; border-width:1px; } One thought was to use a table, but I dont think that is the correct solution either. Ideas? I would like to have the content dynamically resize on page resize and am not opposed to doing it all via JavaScript, but I have a feeling it would be more efficient to do it via CSS ... I just dont know where to begin.

• Can you safely rely upon Yahoo Pipes to offload ETL for your application?

  - by Daniel DiPaolo

  Yahoo Pipes are a very intriguing choice for sort of a poor-man's server-free ETL solution, but would it be a good idea to build an application around one or many Pipes? I've really only used them for toy things here and there, with the only thing I've used longer than a week or two being one amalgamated and filtered RSS feed that I've plugged into Google Reader (which has worked great, but if it goes out for a while I wouldn't notice). So, my question is, would building an application around Yahoo Pipes be reliable (available most of the time)? Ideally it'd be something I could rely on being up 99+% of the time. It looks like the Pipes Terms of Use permit building apps around it, but I am unfamiliar with anyone building anything significant using them.

• BizTalk external assembly namespace and static methods

  - by SteveC

  Is there some restriction in BizTalk 2006 R2 to accessing static methods in external assemblies when the assembly has a "." in the name ? I have the solution set-up with the BizTalk project "FooBar", and the external assembly project "FooBar.Helper" (strongly signed and GAC'ed) with a class "Demo" (public and serializable), which is referenced in the BizTalk project I can create a BizTalk variable of type "FooBar.Helper.Demo" and access an instance method fine, but an expression window the Intellisense shows the FooBar namespace, but if I dot it, I get the error "illegal dotted name" ??? However I can add another project, "ExtComp" with class "Test" and it's static methods are displayed in Intellisense !!! The only difference I can see is the first external assembly has the dot in it

• Scalable (half-million files) version control system

  - by hashable

  We use SVN for our source-code revision control and are experimenting using it for non-source-code files. We are working with a large set (300-500k) of short (1-4kB) text files that will be updated on a regular basis and need to version control it. We tried using SVN in flat-file mode and it is struggling to handle the first commit (500k files checked in) taking about 36 hours. On a daily basis, we need the system to be able to handle 10k modified files per commit transaction in a short time (<5 min). My questions: Is SVN the right solution for my purpose. The initial speed seems too slow for practical use. If Yes, is there a particular svn server implementation that is fast? (We are currently using the gnu/linux default svn server and command line client.) If No, what are the best f/oss/commercial alternatives Thanks

• Qt toggle always on top for a QMainWindow

  void MainWindow::on_actionAlways_on_Top_triggered(bool checked) { Qt::WindowFlags flags = this->windowFlags(); if (checked) { this->setWindowFlags(flags | Qt::CustomizeWindowHint | Qt::WindowStaysOnTopHint); this->show(); } else { this->setWindowFlags(flags ^ (Qt::CustomizeWindowHint | Qt::WindowStaysOnTopHint)); this->show(); } } The above solution works but because setWindowFlags hides the window, it needs to be reshown and of course that doesn't look very elegant. So how do I toggle "always on top" for a QMainWindow without that "flashing" side effect?
