  • How Do I Remove The First 4 Characters From A String If It Matches A Pattern In Ruby

    - by James
    I have the following string: "h3. My Title Goes Here" I basically want to remove the first 4 characters from the string so that I just get back: "My Title Goes Here". The thing is I am iterating over an array of strings and not all have the h3. part in front so I can't just ditch the first 4 characters blindly. I have checked the docs and the closest think I could find was chomp, but that only works for the end of a string. Right now I am doing this: "h3. My Title Goes Here".reverse.chomp(" .3h").reverse This gives me my desired output, but there has to be a better way right? I mean I don't want to reverse a string twice for no reason. I am new to programming so I might have missed something obvious, but I didn't see the opposite of chomp anywhere in the docs. Is there another method that will work? Thanks!

  • Powershell's import-clixml from string

    - by rocku
    Is there any way to run import-clixml cmdlet on a string or xml object? It requires a file path as input to produce ps objects and can't get input from an xml object. Since there is convertto-xml cmdlet which serializes ps object into xml object, why isn't there a convertfrom-xml, which would do the opposite? I am aware of System.Xml.Serialization.XmlSerializer class which would do just that, however I would like to stick with cmdlets to do this. Is there any way to do this with cmdlets (probably just with import-clixml), without creating temporary files?

  • Creating a video chat application for drupal site

    - by Dswabster
    I am trying to write an application for website powered by drupal, basically i would like to create an application only authenticated users are able to use, and users are only allowed to connect with members of the opposite group they are a member of. I have been learning flash builder 4 and learning the basics of actionscript but I am still pretty new to Flash and Flex development. I would like to users to connect using the Adobe Stratus 2 protocol and if possible by authentication on existing site and using membership data from existing mysql database. If anyone could give me a nudge in the right direction on how I should go about creating this application or the next steps i should take, it would be greatly appreciated.

  • What production software have you written in F# in the past year or so that you would previously hav

    - by Peter McGrattan
    Over the last few years F# has evolved into one of Microsoft's fully supported languages employing many ideas incubated in OCaml, ML and Haskell. Over the last several years C# has extended it's general purpose features by introducing more and more functional language features: LINQ (list comprehension), Lamdas, Closures, Anonymous Delegates and more... Given C#'s adoption of these functional features and F#'s taxonomy as an impure functional language (it allows YOU to access framework libraries or change shared state when a function is called if you want to) there is a strong similarity between the two languages although each has it's own polar opposite primary emphasis. I'm interested in any successful models employing these two languages in your production polyglot programs and also the areas within production software (web apps, client apps, server apps) you have written in F# in the past year or so that you would previously have written in C#.

  • Scala: Mixing traits with private fields

    - by Vilius Normantas
    It's not much of a question, it's rather my excitement that it's possible at all! I wrote this little example just to prove the opposite - I expected either a compiler error or one of the values (111 or 222, I wasn't sure). scala> trait T1 { private val v = 111; def getValueT1 = v } scala> trait T2 { private val v = 222; def getValueT2 = v } scala> class T12 extends T1 with T2 scala> val t = new T12 scala> t.getValueT1 res9: Int = 111 scala> t.getValueT2 res10: Int = 222 Why doesn't the v get overridden? Off course this works only as long as vs are private, but still.

  • How to tell the MinGW linker not to export all symbols?

    - by James R.
    Hello, I'm building a Windows dynamic library using the MinGW toolchain. To build this library I'm statically linking to other 2 which offer an API and I have a .def file where I wrote the only symbol I want to be exported in my library. The problem is that GCC is exporting all of the symbols including the ones from the libraries I'm linking to. Is there anyway to tell the linker just to export the symbols in the def file? I know there is the option --export-all-symbols but there seems not to be the opposite to it. Right now the last line of the build script has this structure: g++ -shared CXXFLAGS DEFINES INCLUDES -o library.dll library.cpp DEF_FILE \ OBJECT_FILES LIBS -Wl,--enable-stdcall-fixup EDIT: In the docs about the linker it says that --export-all-symbols is the default behavior and that it's disabled when you don't use that option explicitly if you provide a def file, except when it doesn't; the symbols in 3rd party libs are being exported anyway. EDIT: Adding the option --exclude-libs LIBS doesn't keep their symbols from being exported either.

  • Best approach to send data from a server to an Android device

    - by ElectricDialect
    I am developing an Android app that needs to communicate bi-directionally with a server. By that, I mean either the server or the device can send a message at any time, with an arbitrary amount of time in between messages. Sending data from the device to the server is a common and I think well understood task, but I'm not as sure what the best approach is to go in the opposite direction from the server to the device. I think having the device periodically poll the server may be a bad idea due to latency and the drain on the battery, but I'd be willing to consider this option. My plan at the moment is to send text messages from the server via an email-to-SMS bridge, and to have my app run a service to receive and handle these messages. The question I have is if there are any best practices for this scenario, and if using text messages has some downsides that I have failed to consider. For the sake of this question, I want to assume that users have an unlimited text data plan, so paying per text won't be an issue.

  • Django: Extending User Model - Inline User fields in UserProfile

    - by Jack Sparrow
    Is there a way to display User fields under a form that adds/edits a UserProfile model? I am extending default Django User model like this: class UserProfile(models.Model): user = models.OneToOneField(User, unique=True) about = models.TextField(blank=True) I know that it is possible to make a: class UserProfileInlineAdmin(admin.TabularInline): and then inline this in User ModelAdmin but I want to achieve the opposite effect, something like inverse inlining, displaying the fields of the model pointed by the OneToOne Relationship (User) in the page of the model defining the relationship (UserProfile). I don't care if it would be in the admin or in a custom view/template. I just need to know how to achieve this. I've been struggling with ModelForms and Formsets, I know the answer is somewhere there, but my little experience in Django doesn't allow me to come up with the solution yet. A little example would be really helpful!

  • Verify p2p node

    - by mazzzzz
    Hey guys, I have been working on a p2p namespace for some of my programs. I created a system to encrypt/decrypt the packets send/received with the class. I was using the basic public private key system: 1) encrypt the data with Symmetric encryption 2) encrypt the symmetric key with RSA. Then do the opposite when you decrypted.. I was wondering though, how would you verify if the packet was coming from where it said it was. I was going to use a basic certificate system (where you encrypt with your private RSA key, then they decrypt it with your public key), but I don't know how to do this with C#. I am using the RSACryptoServiceProvider class. Does anyone know how do this? Thanks, Max

  • Retractable button bar using animations

    - by AndroidDev
    I want to create a button bar that is retractable: when the user clicks on a special "handle" button, the button bar should slide out of view partially so only the handle remains visible. When the bar is in retracted state only the handle is visible. Clicking on the handle should "slide out" the button bar so it is completely visible again. Ideally, the bar would start out in retracted state. I have tried some approaches using TranslateAnimation, including using a layout animation or calling "View.startAnimation" when the handle is clicked, but no luck so far. Do you guys have any tips how to approach this? Is there any decent documentation out there regarding Android animations? The documentation I find is sketchy at best. For instance, I found examples that cause a view to slide into view automatically using TranslateAnimation and a LayoutAnimationController when calling "addView", but when I call removeView no animation seems to be triggered at all, even if I set an animation that should create the opposite motion.

  • Conventional Approaches for Passing Data to Back-End?

    - by Calvin
    Hi guys, I'm fairly new to web development, so please pardon the painfully newbie question that's about to follow. My computer science class group and I are developing a web application for class, which is built in Python (under Django) and uses jQuery on the front end. It's primarily an AJAX-ified application, and passing data from the backend to the front end is done through AJAX calls to specific URLs which return JSON. This is probably a stupid question, but what's the conventional approach for passing data in the opposite direction? We don't want to reload the page or anything, so is it an AJAX pass going the other way or something? Thanks in advance for your help!

  • Return a URI for local resource from a webservice

    - by peterkellyonline
    I want to design a webservice that returns a URI to a local resource on the webserver. What is the best (simplest) way to do this in C# using .asmx webservice? Or in other words - how can I get the URI for a physical file path in a webservice? Build a URI using the Uri class and the [WebService] namespace attribute? I know there is Server.MapPath(); that converts a virtual path into the corresponding physical path. I am looking for a way to do the opposite - having the physical path, I want to get not only the virtual path but the full URI. So if the webservice URI is http://some.server.com/services/example.asmx, the virtual path to the file I want to return is /Updates/file.xml and the physical path to that file is C:\Updates\file.xml what is the best way to get the URI http://some.server.com/updates/file.xml from that information? Thanks

  • Refining Solr searches, getting exact matches?

    - by thebluefox
    Afternoon chaps, Right, I'm constructing a fairly complex (to me anyway) search system for a website using Solr, although this question is quite simple I think... I have two search criteria, location and type. I want to return results that are exact matches to type (letter to letter, no exceptions), and like location. My current search query is as follows ../select/?q=location:N1 type:blue&rows=100&fl=*,score&debugQuery=true This firstly returns all the type blue's that match N1, but then returns any type that matches N1, which is opposite to what I'm after. Both fields are set as textgen in the Solr schema. Any pointers? Cheers gang

The reason I am doing this is for a VBulletin forum signature since it marquees left to right. I have tried editing the animation in Photoshop and I flipped the canvas to horizontal... I can't figure this out.. I've been at it for HOURS. hah Also if anyone can make it just a little darker that would be amazing.

  • Pushing notifications to a JavaScript?

    - by Michael Stum
    I'm just wondering if there is a way to have a server push information to a JavaScript function. Essentially I have a Dashboard-type page that has a javaScript function to get updates from the server and update the dashboard. I would like my server to be able to "ping" the JS. I don't even know how that could be possible (I'm guessing Twitter and Facebook use polling?), but I'd thought I ask. I heard of Comet, but I don't know if that works with a plain standard IIS 7 installation? (It's a SharePoint 2010 site if that matters in any way) If I understand it correctly, Comet is essentially a constantly open connection, so it seems like it's actually the opposite of what I want (reducing # of requests and therefore load)

  • How to return an enum ID instead of the enum text in WebAPI

    - by Rodney
    I am using the WebAPI with .NET 4.5. I have a enum called DareStatus which is a list of statuses and their corresponding integer ID's. To minimize bandwidth traffic I want to send the int values of the enums, not the full text as it is currently doing. (I have control over the client so I can map it on the clientside). The strange thing is that in my RTFM-ing everyone seems to have the opposite issue! http://www.ftter.com/desktopmodules/framework/api/dare/getalldares public enum DareStatus : int { All = 0, Accepted = 2, Pending = 1, Declined = 3, Cancelled = 4, Failed = 5, Won = 6 } public IEnumerable<DareInfo> GetDares() { IEnumerable<DareInfo> dareInfos; using (IDataContext ctx = DataContext.Instance()) { var rep = ctx.GetRepository<DareInfo>(); dareInfos = rep.Get(); } return dareInfos; }

  • Select records from XML column (SQL Server 2005) based on node order

    - by jdoe
    I have a column in a SQL Server 2005 table defined as an XML column. Is there a way to select records from this table based on the order of two nodes in that column? For example, we have the following structure in our XML: <item> <latitude/> <longitude/> </item> I want to see if there are any records that have latitude/longitude in the opposite order i.e. <longitude/> then <latitude/>. I've tried some XPath expressions but with no luck.

  • I need help understanding what Exercise 5-12 is asking for in the C Programming Language book.

    - by marsol0x
    K&R C Programming Language: pg. 105 Extend entab and detab to accept the shorthand entab -m +n to mean tab stops every n columns, starting at column m. entab replaces a number of spaces with a tab character and detab does the opposite. The question I have concerns the tab stops and entab. I figure that for detab it's pretty easy to determine the number of spaces needed to reach the next tab stop, so no worries there. With entab, replacing spaces with tabs is slightly more difficult since I cannot for sure know how large the tab character goes to its own tab stop (unless there is a way to know for sure). Am I even thinking about this thing properly?

  • Sliding & Fading controls on a C# form

    - by Tommy
    Hey there, I'm trying to implement a way to slide&fade controls around (more than one at the same time possibly) elegantly. So in other words, say i had a picture in the top left corner, and a texbox in the bottom right corner, i'd like to be able to have them slide. not just snap. slide, to the opposite corners and replace eachothers position. Ive been working for awhile but have not come up with anything efficient, even just some of the basic math calculations would be a great start.

  • How can I tell what events fire from GXT?

    - by CoverosGene
    I cannot seem to find any documentation of what events fire and when in GXT. The API docs have lists of all the events that could fire (in Events). And it describes how to handle events that you catch. But I'm interested in the opposite side, which events are fired when I take a certain action. I can set some listeners for various different components, or I can use addListener with a specific event code to catch individual events. That's spotty, and I seem to be using trial-and-error to guess what I might want to catch. Is there a way to log all the events that are firing? Or catch all of them so I could look at them in a debugger? Or is there some documentation I am missing that has the information? Something along the lines of "when you click on a widget, a ButtonEvent is fired. Events.x is fired on the hover, Events.y on the click."

  • java shift elements in array

    Hey I am trying to shift elements forward sending the last element in the array to data[0]. I did the opposite direction but I can't seem to find my mistake in going in this direction. Pos is users inputed shift times amount temp is the temporary holder. data is the array if(pos 0) { do { temp = data[data.length -1]; for(int i =0; i < data.length; i++) { if(i == data.length-1) { data[0] = temp; } else { data[i+1] = data[i]; } } pos--; }while(pos > 0); } Thanks.
