  • Parsing / Extracting Text from String in Rails?

    - by user641116
    I have a string in Rails, e.g. "This is a Twitter message. #books War & Peace by Leo Tolstoy. I love this book!", and I want to parse the text and extract only certain phrases, like "War & Peace by Leo Tolstoy". Is this a matter of using Regex and lifting the text between "#books" to "."? What if there's no structure to the message, like: "This is a Twitter message #books War & Peace by Leo Tolstoy I love this book!" or "This is a Twitter message. I love the book War & Peace by Leo Tolstoy #books" How can I reliably pull the phrase "War & Peace by Leo Tolstoy" without knowing the phrase ex ante. Are there any gems, methods, etc. that can help me do this? At the very least, what would you call what I'm trying to do? It will help me search for a solution on Google. I've tried a few searches on "parsing" with no luck.

  • GridView not DataBinding Automatically after ObjectDataSource Select Method

    - by John Polvora
    I've created a objectadasource that returns a datatable, the gridview is binded to this datasource. the ODS have parameters assigned on the Page_Load event, and the ODS returns the data ok and the gridview shows it fine. the problem is i have a textbox with a filter. first I created a filterexpression in gridview, using the contents of the textbox, worked fine for me. but now I've enabled the paging in gridview. then the filterexpression is not useful now, since the ODS returns only the rows of the pagesize of gridview. I did a new ODS method that select data from parameters page and pagesize according to GridView, and it's OK. now my filter textbox passes his text property to a parameter of the ods select method, then the ods gets the data based on my filter and shows it in the grid. on the Page_Load: ObjectDataSource_Lista.SelectParameters["search"].DefaultValue = filter; ObjectDataSource_Lista.SelectParameters["id"].DefaultValue = ID.ToString(); but when I change the value of the filter, the grid doesn't refresh. on debugging. I see that the ODS Select Method is refreshed ok, but the GridView don't. So I need to call mannually the Databind() method of the grid, to refresh data. the problem is, I have a commandbutton on the grid, and if I manually databind(), the command button stops functioning, generating Page ValidateRequest errors. My question is: how to databind() the grid automatically after the datasource refreshed? ps: on the ODS Selected event, causes a infinite loop and the debug webserver crashes. Temporary solution: Created a Variable private bool wasdatabound; on the event GridView_Databound, set wasdatabound = true; on the Page_PreRenderComplete, if ((GridView1.Visible) && (!databounded)) GridView1.DataBind();

  • Prevent illegal behavior to the registered user

    - by Al Kush
    I am building a website in which this website will be focused on the publishing of novels. Every writers who publish their novels with us will get a royalty from us. And this royalty comes from the user or the reader who read the novel online in our website. When a user search for a novel and want to read that, they will click a link to the page which its content is that novel. The html page for each novels will have a session function that first will force them to login or register to make a payment such as with a credit-card or paypal before accessing that html page. My problem now is if the user has succesfully login and access the html page, I am afraid if the user will copy the content of the novel. Some disccussion out here How to Disable Copy Paste (Browser) have a solution to create it in Flash so that it can't be coppied-paste. But the I think, if the user who access it is a web developer like us they will try to find the path of the file from the link in the page source, and then they can steal it. For now I think it is enough I am explaining this. I hope anyone fully accept this problem (question) with a good idea to solve it.

  • Is it possible for onunload confirm to open a new url in the same window?

    - by Dan Peschio
    Hi - this is my first post and I'm a JS novice, so please forgive my ignorance... Heres my question, its in two parts: 1.) At onunload I want an alert that asks the user if they would like to go to a related URL. The code I'm using works, but it open the URL in a new window and this can be blocked by a pop-up blocker even though the user has opted-in. Is there a way to have it open in the same window and negate the pop-up blocker? 2.) is there a way to take the onunload function out of the body tag and put it the script? Heres the code I'm using: <script language=javascript> function confirmit() { var closeit= confirm("Before you go would you like to add your press kit to the Search Press Kits database?"); if (closeit == true) {window.open("http://NEWURLHERE.com");} else {window.close();} } </script> </head> <body onunload="confirmit();"> peace </body> Thanks in advance, Dan

  • How to "escape" the JavaScript class keyword to specify a CSS class value.

    - by Robert Claypool
    C# allows a reserved word to be used as a property name via the ampersand. e.g. // In ASP.NET MVC, we use @class to define // the css class attribute for some HtmlHelper methods. var htmlObject = new { readonly = "readonly", @class = "ui-state-highlight" } I want to do the same in JavaScript. e.g. function makeGrid(grid, pager) { grid.jqGrid({ caption: 'Configurations', colNames: ['Id', 'Name'], colModel: [ { name: 'Id', index: 'Id' }, { name: 'Name', index: 'Name', editable: true, editoptions: { readonly: 'readonly', class: 'FormElement readonly' } }, ], pager: pager, url: 'www.example.com/app/configurations") %>', editurl: 'www.example.com/app/configurations/edit") %>' }).navGrid(pager, { edit: true, add: false, del: false, search: false }, {}, {}, {}); } Note class: 'FormElement readonly' is supposed to set the css class value on jqGrid's edit dialog, but IE errors out on the reserved word. Is there an escape character in JavaScript too? #class? @class? &class? Otherwise, how might I tell jqGrid to set the css class on the popup editor? Thank you.

  • Certain transformations in Open Inventor(Coin3D)

    - by Marc
    Hi, I am quite new to Open Inventor(Coin3D) and have the following problem: I have a SoSelection holding a root node(also SoSeparator). And the root node holds a number of SoSeparator nodes. Each of these SoSeparator nodes holds a SoTransform node and a SoCube node. When I select one cube node I want all other cubes within a certain distance to the selected cube to arrange in a circle arround the selected cube. (Moreover all of the cubes should be on a plane than) An additional information: My cubes are always oriented in the camera direction with (cubeTransform_-rotation.connectFrom(&camera_-orientation) Assuming the selected cube is the center of the circle, how do I translate the other cubes in a circle on a plane(perpendicular to the vector between the selected cube and the camera)? Especially how do I find coordinates on the plain on which the circle should be which have a certain distance from the Axis (from center cube to camera). What I already did is to search for the for all cubes within a certain distance as soon as one cube is selected. As a result I already have the required separators (which are holding the according SoTransforms and SoCubes) in a SoPathList. Now I want to arrange the cubes by modifing the according SoTransform-translation values. Regards Mark

  • Push different views from a table.

    - by Tanner
    Hello All, Ive been following a tutorial to implement a search bar ( http://www.iphonesdkarticles.com/2009/01/uitableview-searching-table-view.html ) However I cant seem to push different views. Here is what my didsSelectRowAtIndexPath looks like. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *selectedCountry = nil; if(searching) selectedCountry = [copyListOfItems objectAtIndex:indexPath.row]; else { NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section]; NSArray *array = [dictionary objectForKey:@"Countries"]; selectedCountry = [array objectAtIndex:indexPath.row]; } //Initialize the detail view controller and display it. if ([[listOfItems objectAtIndex:indexPath.row] isEqual:@"neon"]){ Neon *abo = [[Neon alloc] initWithNibName:@"Neon" bundle:nil]; //dvController.selectedCountry = selectedCountry; [self.navigationController pushViewController:abo animated:YES]; [abo release]; } } And here is the debuger message when I click on neon: 2010-05-09 08:47:27.516 iTeachU[3821:307] * Terminating app due to uncaught exception 'NSRangeException', reason: ' -[NSMutableArray objectAtIndex:]: index 60 beyond bounds [0 .. 0]' ** Call stack at first throw: terminate called after throwing an instance of 'NSException' Program received signal: “SIGABRT”. If anyone has a way to push views based on the cells text it would be greatly appreciated. Thanks

  • Programmatically talking to a Serial Port in OS X or Linux

    - by deadprogrammer
    I have a Prolite LED sign that I like to set up to show scrolling search queries from a apache logs and other fun statistics. The problem is, my G5 does not have a serial port, so I have to use a usb to serial dongle. It shows up as /dev/cu.usbserial and /dev/tty.usbserial . When i do this everything seems to be hunky-dory: stty -f /dev/cu.usbserial speed 9600 baud; lflags: -icanon -isig -iexten -echo iflags: -icrnl -ixon -ixany -imaxbel -brkint oflags: -opost -onlcr -oxtabs cflags: cs8 -parenb Everything also works when I use the serial port tool to talk to it. If I run this piece of code while the above mentioned serial port tool, everthing also works. But as soon as I disconnect the tool the connection gets lost. #!/usr/bin/python import serial ser = serial.Serial('/dev/cu.usbserial', 9600, timeout=10) ser.write("<ID01><PA> \r\n") read_chars = ser.read(20) print read_chars ser.close() So the question is, what magicks do I need to perform to start talking to the serial port without the serial port tool? Is that a permissions problem? Also, what's the difference between /dev/cu.usbserial and /dev/tty.usbserial?

  • Android Home Screen Widget Failing with EditText

    - by Chris
    Whenever I add an EditText widget to the layout of my home screen widget (confusing how the term "widget" is being used twice in the Android lexicon :-/ ), I receive the "Problem Loading Widget" error box. Here is the layout I'm attempting; if you remove the EditText, it works... < RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" <Button android:id="@+id/button_generate" android:layout_width="54px" android:layout_height="54px" android:text="Generate" android:textSize="10sp" android:gravity="center" android:layout_alignParentTop="true" android:layout_toRightOf="@+id/edittext_key"> </Button> <TextView android:id="@+id/textview_hash" android:layout_width="75px" android:layout_height="45px" android:text="Password" android:textSize="11sp" android:gravity="left" android:layout_alignParentTop="true" android:layout_toLeftOf="@+id/edittext_key"> </TextView> <EditText android:id="@+id/edittext_data2" android:layout_width="200px" android:layout_height="50px" android:textSize="12sp" android:layout_marginTop="20px" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"> </EditText> </RelativeLayout> Now, the Google Search home screen widget has an EditText, so it's obviously legal to implement. Any thoughts on why this is not working?

  • Circular dependecy in winforms app using Castle Windsor

    - by Sven
    Hello, I was experimenting a little bit with Castle winforms in a winforms project. I wanted to register all my form dependencies with Castle windsor. This way I would have a single instance for all my forms. Now I have some problem though. I'm in a situation that form x has a dependency on form y and form y has a dependency on form x. Practical example maybe: form x is used to create an order, form y is the screen that has a list of customers. From form x there is a button to select a customer for the order. This will open form y where ou can search the customer. There is a button that lets you add the found customer to the order. It will call a method on form x and passes the selected customer object. I could do this with events. Raise an event in form y and listen for that in form x. But isn't there a way around the circular dependency in Castle Windsor, lazy registration or something? Can anyone help me out? Thanks in advance

  • WYSIHAT Photos upload not working - Paperclip - Ruby on Rails

    - by bgadoci
    I just successfully installed WysiHat in my rails blog. Seems that the 'add a picture' feature is not working. It successfully allows me to find and select a picture from my desktop but upon clicking save, it does nothing. I also have Paperclip successfully installed. I am wondering if this may have something to do with it. Perhaps Paperclip is getting in the way, or, perhaps I need to connect Paperclip and WysiHat somehow. Any ideas? (let me know if I need to post any code). Also, WysiHat-engine uses facebox, not sure if that is relevant. UPDATE: Added Server Log, looks like paperclip is saving it so not sure what else is going wrong.

  • How to propagate .java file change to .class under eclipse, tomcat & stripes

    - by BigBourin
    Hi, i'm new to java and i got some problems. i'm developping a web application using the framework stripes on tomcat 6.0. I'm working with eclipse EE on windows. i successfully managed to get the stripes example application (called Bugzooky) up and running on my tomcat server. I imported the .war file and stripes libs in Eclipse. Here is the stripes archive containing the examples and libs But now i'm trying to change the example source files to learn how does it work. but whatever the modification made to the source files "WebContent/WEB-INF/src/*.java", nothing change! even after restarting the server. i noticed that the classes are compiled into .class files in the "ImportedClasses" folder, and tomcat always use these files, they are never updated, and if i removed one of them, the application just don't start. it look like my source files don't exists! I also tried to build my webapp from scratch, but when i tried to use the features used in the example files (like SecurityFilter.java): import javax.servlet.Filter; import javax.servlet.FilterChain; import javax.servlet.FilterConfig; import ... It ends up with plenty of: the import javax.servlet.Filter cannot be resolved I checked the Librairies and it look like i'm using exactly the same as the example. It's probably something i didn't understood about java but i googled 100 times yesterday, and i can't find the solution (i probably didn't search the right place because i don't really understand my problem). I hope you'll be able to help me.

  • STL operator= behavior change with Visual Studio 2010?

    - by augnob
    Hi, I am attempting to compile QtScriptGenerator (gitorious) with Visual Studio 2010 (C++) and have run into a compile error. In searching for a solution, I have seen occasional references to compile breakages introduced since VS2008 due to changes in VS2010's implementation of STL and/or c++0x conformance changes. Any ideas what is happening below, or how I could go about fixing it? If the offending code appeared to be QtScriptGenerator's, I think I would have an easier time fixing it.. but it appears to me that the offending code may be in VS2010's STL implementation and I may be required to create a workaround? PS. I am pretty unfamiliar with templates and STL. I have a background in embedded and console projects where such things have until recently often been avoided to reduce memory consumption and cross-compiler risks.

  • manage.py runserver throws an ImportError with my appname, MacPorts issue on OSX?

    - by christmasgorilla
    I've been developing a Django app for weeks locally on OSX 10.6.3. Recently, I rebooted my machine and went to start my development environment up. Here's the error: cm:myApp cm$ python manage.py runserver Traceback (most recent call last): File "manage.py", line 11, in execute_manager(settings) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 360, in execute_manager setup_environ(settings_mod) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 343, in setup_environ project_module = import_module(project_name) File "/Library/Python/2.6/site-packages/django/utils/importlib.py", line 35, in import_module import(name) ImportError: No module named myapp I'm pretty new to Django / Python. Digging around, it's possible that this might be due to MacPorts. Initially, I had a rough time getting Django up and running and I no longer remember if I'm using the Django from a MacPorts install or from easy_install. How do I tell? (I'd prefer not to reinstall everything). Also, why is the camel casing in my app name gone in the ImportError message? When I search for "myapp" in my django project, I don't find it without camelcase anywhere. And what causes MacPorts to work for a while but then break? As a few other details, from settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'south', 'registration', 'pypaypal', 'notifier', 'myApp.batches', )

  • Speed of CSS

    - by Ólafur Waage
    This is just a question to help me understand CSS rendering better. Lets say we have a million lines of this. <div class="first"> <div class="second"> <span class="third">Hello World</span> </div> </div> Which would be the fastest way to change the font of Hello World to red? .third { color: red; } div.third { color: red; } div.second div.third { color: red; } div.first div.second div.third { color: red; } Also, what if there was at tag in the middle that had a unique id of "foo". Which one of the CSS methods above would be the fastest. I know why these methods are used etc, im just trying to grasp better the rendering technique of the browsers and i have no idea how to make a test that times it. UPDATE: Nice answer Gumbo. From the looks of it then it would be quicker in a regular site to do the full definition of a tag. Since it finds the parents and narrows the search for every parent found. That could be bad in the sense you'd have a pretty large CSS file though.

  • please clarify some aspects of AJAX with ASP.NET web forms for a beginner

    - by citrus
    Im familiar with asp.net web forms. I would now like to move on to writing web applications that use AJAX. I would like to get to the stage where I can create an app: that has "edit in place" (no page reload) where i can reorder images using drag and drop (also saves the order to DB) that has google like search suggestions while typing on the fly 1)So do I need to learn how to use AJAX.net and Jquery(my JS library of choice)? Can I make do using only AJAX.net or only Jquery? 2)As far a I know, Jquery will allow me to perform client side manipulations/actions and AJAX.net is the part that will allow me to connect some of my actions to the Server. EG. if I wanted to re-order elements using drag and drop, I would use Jquery, but in order to save the result of the re-order to the DB I would have to use AJAX.net correct? 2a)So In order to learn how to do the above Im thinking I should first learn Jquery so I know how to manipulate/ select elements, and then I can lean how to save these changes to the DB. 3)I searched the books titled "ASP.net AJAX in action" and ASP.net 3.5 AJAX, both of these books did not contain any references to "Jquery". Is this because they may be using a different JS library, or perhaps the book focuses on the AJAX user controls? I just found it confusing that 2 popular AJAX books dont make any reference to Jquery. Thanks for any help.

  • Navigation view system with webview problem with touches!

    - by Gonçalo Falcão
    Hello i have search everything and i didn't figure this out! I have a tab bar controller with 5 navigation controlls, in one of the navigation control, i have a view, with a table view inside, and when i click that item i push a new view, that view have view -webview -view i create that second view(is transperant) because i need to handle a single tap to hide my toolbar and navigation bar, and the webview was eating all the touches! I put that view and implement on the view controller -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch* touch = [touches anyObject]; if(touch.tapCount == 2){ [NSObject cancelPreviousPerformRequestsWithTarget:self]; } [[wv.subviews objectAtIndex:0] touchesBegan:touches withEvent:event]; [super touchesBegan:touches withEvent:event]; } -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ [[wv.subviews objectAtIndex:0] touchesMoved:touches withEvent:event]; [super touchesMoved:touches withEvent:event]; } -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch* touch = [touches anyObject]; if(touch.tapCount == 1){ [self performSelector:@selector(hideBars) withObject:nil afterDelay:0.3]; } [[wv.subviews objectAtIndex:0] touchesEnded:touches withEvent:event]; [super touchesEnded:touches withEvent:event]; } -(void) touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event{ [[wv.subviews objectAtIndex:0] touchesCancelled:touches withEvent:event]; [super touchesCancelled:touches withEvent:event]; } wv is my UIWebView IBOutlet now i can get the the touches in my controller and send them to my webview. So i thought everything was working, i'm able to scroll, but now when i have links i'm not able to click them. And the webview is detecting the links i have made that test. So any other way to implements this to get the touches in the links, or i should change this workaround to hide the toolbars so i can have the full functionability of the webview? Thks for the help in advance.

I think I've managed to get the required dependencies installed using yum: sudo yum install librsvg2 sudo yum install cairo The Makefile contains: MYCFLAGS=`pkg-config --cflags librsvg-2.0 cairo-pdf` -Wall -Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations - Wnested-externs -fno-strict-aliasing MYLDFLAGS=`pkg-config --libs librsvg-2.0 cairo-pdf` After typing 'make', the first couple of lines of output are: cc `pkg-config --cflags librsvg-2.0 cairo-pdf` -Wall -Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -fno-strict-aliasing `pkg-config --libs librsvg-2.0 cairo-pdf` svg2pdf.c -o svg2pdf Package librsvg-2.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `librsvg-2.0.pc' to the PKG_CONFIG_PATH environment variable No package 'librsvg-2.0' found There is no librsvg-2.0.pc on this system (but there is when I installed this using macports on my macbookpro). How should I get this package linked? Should I change the Makefile, and if so, to what? Should I generate the .pc files, and if so, how? Or is there another way to resolve this? Or, has anyone been successful at installing svg2pdf on centos, and, if so, how did you manage it? I don't have much experience on linux, so I might be missing something obvious.

  • How to protect/monitor your site from crawling by malicious user

    - by deathy
    Situation: Site with content protected by username/password (not all controlled since they can be trial/test users) a normal search engine can't get at it because of username/password restrictions a malicious user can still login and pass the session cookie to a "wget -r" or something else. The question would be what is the best solution to monitor such activity and respond to it (considering the site policy is no-crawling/scraping allowed) I can think of some options: Set up some traffic monitoring solution to limit the number of requests for a given user/IP. Related to the first point: Automatically block some user-agents (Evil :)) Set up a hidden link that when accessed logs out the user and disables his account. (Presumably this would not be accessed by a normal user since he wouldn't see it to click it, but a bot will crawl all links.) For point 1. do you know of a good already-implemented solution? Any experiences with it? One problem would be that some false positives might show up for very active but human users. For point 3: do you think this is really evil? Or do you see any possible problems with it? Also accepting other suggestions.

  • Jquery Autocomplete plugin with Django (Trey Piepmeier solution)

    - by Sally
    So, I'm basing my code on Trey's solution on: http://solutions.treypiepmeier.com/2009/12/10/using-jquery-autocomplete-with-django/ The script is: <script> $(function() { $('#id_members').autocomplete('{{ object.get_absolute_url }}members/lookup', { dataType: 'json', width: 200, parse: function(data) { return $.map(data, function(row) { return { data:row, value:row[1], result:row[0] }; }); } }).result( function(e, data, value) { $("#id_members_pk").val(value); } ); } ); </script> The views.py: def members_lookup(request, pid): results = [] if request.method == "GET": if request.GET.has_key(u'q'): value = request.GET[u'q'] # Ignore queries shorter than length 1 if len(value) > 2: model_results = Member.objects.filter( Q(user__first_name__icontains=value) | Q(user__last_name__icontains=value) ) results = [ (x.user.get_full_name(), x.id) for x in model_results ] json = simplejson.dumps(results) print json return HttpResponse(json, mimetype='application/json') The problem is: It stops refining the search results after the initial lookup. For example: If I set len(value) 2, after I type the 3rd character it will give me a list of suggestions. But if I keep on typing the 4th or 5th character, the list of suggestions doesn't change. Any suggestions on why this is?

  • Multiple dynamic timers

    - by Rickard
    I am working on a project where I need to let the user create one (or more) timers to fire off an event. The user is supposed to define variables such as if the timer should be active and how often the timer will fire along with some other variables of what will happen when the timer is fiering. All these variables are stored in a dictionary (Disctionary) where the object holds all the variables the user has set and the string is the name that the user has chosen for this timer. I then want my program to loop through this dictionary and search for all objects which has the variable t_Active set to true (this I have already achieved). What I need help with figuring out is the follwoing: When it detects the variable, and if it's set to true, I need the program to see if there is already a timer created for this. If it isn't, it should create one and set the relevant parameters for the timer. The two variables t_num and t_period should decide the interval of the timer. t_num is an int and t_period is a string which will be set to either minutes, hours or days. Combining t_num with 60000 (minutes), 3600000 (hours) or 86400000 should give the corrct interval. But how would I go on about programatically create a timer for each user-defined active object? And how do I get the program to detect wether or not a timer has already been created? I have been searching both here and on google, but so far I haven't come across something that makes sense to me. I am still learning C#, so what make sense to you guys may not neccessarilly make sense to me yet. :) I hope I have explaned what I need good enough, please do ask me to clarify if you don't get me. Edit: Maybe I should also mention that the mentioned dictionary will also be saved to an XML file to that the user can pick up all the settings they made at any time.

  • Sorting, Filtering and Paging in ASP.NET MVC

    - by ali62b
    What is the best approach to implement these features and which part of project would involved? I see some example of JavaScript grids, but I'm talking about a general approach which best fits the MVC architecture. I've considered configuring routes and models to implement these features but I don't have a clear idea that if this is the right approach to implementing such features. On the one hand, I think if we put logic in routes (item/page/sort/), we would have benefits like bookmarking and avoiding JavaScript. On the other hand if we use JavaScript grids, we can have behavior like the old school grid views in ASP.NET web forms. I find that using HTML helpers may be useful for paging, but have no idea if they are good for sorting or not. I've looked at jQuery, tableSorter and quick search plug-ins, but they work just on the currently-fetched data and won't help in real sorting and filtering that may need to touch the database. I have some thoughts on using these tools side by side with AJAX to get something which works, but I have no idea if there are similar efforts done yet anywhere. Another approach I looked at was using Dynamic Data on web forms, but I didn't find any suggestions out there as to whether or not it is a good idea to integrate MVC and DD. I know implementing filtering and sorting for an individual case is simple (although it has some issues like using Dynamic LINQ, which is not yet a standard approach), but creating a sorting or filtering tool which works in all cases is the idea I'm looking for. (Maybe this is because I want have something in hand when web form developers are wondering why I'm writing same code each time I want to implement a sort scenario for different Entities).

  • Better ways to implement a modulo operation (algorithm question)

    - by ryxxui
    I've been trying to implement a modular exponentiator recently. I'm writing the code in VHDL, but I'm looking for advice of a more algorithmic nature. The main component of the modular exponentiator is a modular multiplier which I also have to implement myself. I haven't had any problems with the multiplication algorithm- it's just adding and shifting and I've done a good job of figuring out what all of my variables mean so that I can multiply in a pretty reasonable amount of time. The problem that I'm having is with implementing the modulus operation in the multiplier. I know that performing repeated subtractions will work, but it will also be slow. I found out that I could shift the modulus to effectively subtract large multiples of the modulus but I think there might still be better ways to do this. The algorithm that I'm using works something like this (weird pseudocode follows): result,modulus : integer (n bits) (previously defined) shiftcount : integer (initialized to zero) while( (modulus<result) and (modulus(n-1) != 1) ){ modulus = modulus << 1 shiftcount++ } for(i=shiftcount;i>=0;i++){ if(modulus<result){result = result-modulus} if(i!=0){modulus = modulus << 1} } So...is this a good algorithm, or at least a good place to start? Wikipedia doesn't really discuss algorithms for implementing the modulo operation, and whenever I try to search elsewhere I find really interesting but incredibly complicated (and often unrelated) research papers and publications. If there's an obvious way to implement this that I'm not seeing, I'd really appreciate some feedback.
