  • Fork or copy a users browser session in IE

    - by jmoeller
    Is it possible to fork a users session (or do something similar) in a Internet Explorer plugin? I want to process the page the user is on when they click a button in the toolbar. To avoid interrupting the users browsing, I'd like to "copy" everything so I can parse and process the page in the background. The processing can involve things such as loading the content of the result links on a Google search, if that's where the button was clicked. So - what I basically want is to imitate "Ctrl+N" but hide the window from the user, so they won't be interrupted. As you can see, if you fill out and submit the form on http://www.snee.com/xml/crud/posttest.html and press "Ctrl+N", everything posted will still appear in the new window, but it won't post the data twice. I was thinking of somehow copying the IWebBrowser2, but: I'm not sure if that's possible (I haven't been able to find any information on MSDN) I don't know if it copies the sessions as well. Creating a new instance of the IWebBrowser2 and simply navigating to the current URL isn't a valid solution as POST-variables of course doesn't get carried over.

  • Throttling outbound API calls generated by a Rails app

    - by Sharpie
    I am not a professional web developer, but I like to wrench on websites as a hobby. Recently, I have been playing with developing a Rails app as a project to help me learn the framework. The goal of my toy app is to harvest data from another service through their API and make it available for me to query using a search function. However, the service I want to pull data from imposes a rate limit on the number of API calls that may be executed per minute. I plan on having my app run a daily update which may generate a burst of API calls that far exceeds the limit provided by the external service. I wish to respect the performance of the external site and so would like to throttle the rate at which my app executes the calls. I have done a little bit of searching and the overwhelming amount of tutorial material and pre-built libraries I have found cover throttling inbound API calls to a web app and I can find little discussion of controlling the flow of outbound calls. Being both an amateur web developer and a rails newbie, it is entirely possible that I have been executing the wrong searches in the wrong places. Therefore my questions are: Is there a nice website out there aggregating Rails tutorials that has material related to throttling outbound API requests? Are there any ruby gems or other libraries that would help me throttle the requests? I have some ideas of how I might go about writing a throttling system using a queue-based worker like DelayedJob or Resque to manage the API calls, but I would rather spend my weekends building the rest of the site if there is a good pre-built solution out there already.

  • 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

  • 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.

  • How to localize an app on Google App Engine?

    - by Petri Pennanen
    What options are there for localizing an app on Google App Engine? How do you do it using Webapp, Django, web2py or [insert framework here]. 1. Readable URLs and entity key names Readable URLs are good for usability and search engine optimization (Stack Overflow is a good example on how to do it). On Google App Engine, key based queries are recommended for performance reasons. It follows that it is good practice to use the entity key name in the URL, so that the entity can be fetched from the datastore as quickly as possible. Currently I use the function below to create key names: import re import unicodedata def urlify(unicode_string): """Translates latin1 unicode strings to url friendly ASCII. Converts accented latin1 characters to their non-accented ASCII counterparts, converts to lowercase, converts spaces to hyphens and removes all characters that are not alphanumeric ASCII. Arguments unicode_string: Unicode encoded string. Returns String consisting of alphanumeric (ASCII) characters and hyphens. """ str = unicodedata.normalize('NFKD', unicode_string).encode('ASCII', 'ignore') str = re.sub('[^\w\s-]', '', str).strip().lower() return re.sub('[-\s]+', '-', str) This works fine for English and Swedish, however it will fail for non-western scripts and remove letters from some western ones (like Norwegian and Danish with their œ and ø). Can anyone suggest a method that works with more languages? 2. Translating templates Does Django internationalization and localization work on Google App Engine? Are there any extra steps that must be performed? Is it possible to use Django i18n and l10n for Django templates while using Webapp? The Jinja2 template language provides integration with Babel. How well does this work, in your experience? What options are avilable for your chosen template language? 3. Translated datastore content When serving content from (or storing it to) the datastore: Is there a better way than getting the *accept_language* parameter from the HTTP request and matching this with a language property that you have set with each entity?

  • haskell: a data structure for storing ascending integers with a very fast lookup

    - by valya
    Hello! (This question is related to my previous question, or rather to my answer to it.) I want to store all qubes of natural numbers in a structure and look up specific integers to see if they are perfect cubes. For example, cubes = map (\x -> x*x*x) [1..] is_cube n = n == (head $ dropWhile (<n) cubes) It is much faster than calculating the cube root, but It has complexity of O(n^(1/3)) (am I right?). I think, using a more complex data structure would be better. For example, in C I could store a length of an already generated array (not list - for faster indexing) and do a binary search. It would be O(log n) with lower ?oefficient than in another answer to that question. The problem is, I can't express it in Haskell (and I don't think I should). Or I can use a hash function (like mod). But I think it would be much more memory consuming to have several lists (or a list of lists), and it won't lower the complexity of lookup (still O(n^(1/3))), only a coefficient. I thought about a kind of a tree, but without any clever ideas (sadly I've never studied CS). I think, the fact that all integers are ascending will make my tree ill-balanced for lookups. And I'm pretty sure this fact about ascending integers can be a great advantage for lookups, but I don't know how to use it properly (see my first solution which I can't express in Haskell).

  • 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.

  • 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();

  • osCommerce custom PHP page

    - by Afrosimon
    Hello! One of my client has an old osCommerce website and while working on it I have to implement what I would call "custom php page", i.e. a page which query a MySQL table, not related to osCommerce, and list the result. I'm not sure of the version, this trick I have seen a lot didn't gave me any result : http://www.clubosc.com/how-to-know-what-version-of-oscommerce-you-are-using.html . And I'm having a hard time doing this seemingly simple task, since osCommerce doesn't allow any php code in the page creation, and I didn't find any module giving me this possibility (not that it is easy to search in this mess : http://addons.oscommerce.com/). At this point I figured it would be easier to just hack'n slash through the code and come up with a custom page : I copied the index.php (the entry point in the application) : <?php require('includes/application_top.php'); if(!$smarty->is_cached($sContentPage, $sCachingGroup)) { //we switch on the content recognition require('includes/pages/' . $sContentClass . '.php'); } $smarty->display($sContentPage, $sCachingGroup); require(DIR_WS_INCLUDES . 'application_bottom.php'); ?> Here I gave a specific value to $sContentClass (with or without the if makes no difference) and customize the corresponding PHP file so it show my custom content but also initialize the same variable than those other PHP file in the pages/ folder. But alas, all of this curious and dubious code simply return me the home page. So here I am, is there an osCommerce Guru around here, or would anyone has a better idea (oh and I also posted on the osCommerce forum, but I'm still waiting for a response...)? Thanks a lot in advance.

  • Google GWT cross-browser support: is it BS ?

    - by Tim
    I developed a browser-deployed full-text search app in FlashBuilder which communicates RESTfully with a remote web-server. The software fits into a tiny niche--it is for use with ancient languages not modern ones, and there's no way I'm going to make any money on it but I did spend a lot of time on it. Now that Apple won't allow Flash on the iPad, I'm looking for a 100% javascript solution and was led to consider GWT. It looked promising, but one of the apps being "showcased" as a stellar example of what can be done with GWT has this disclaimer on their website (names {removed} to protect the potentially innocent) : Your current web browser (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5) is not officially supported by {company and product name were here}. If you experience any problems using this site please install either Microsoft Internet Explorer 6+ or Mozilla Firefox 3.5+ before contacting {product name was here} Support. What gives when GWT apps aren't "officially" supported on Chrome? What grade (A, B, C, D, F) would you give to GWT for cross-browser support? For folks who don't get these kinds of letter grades, A is "excellent" and "F" is failure, and "C" is average. Thanks for your opinions.

  • 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.

  • calling asp.net mvc action method using jquery post method expires the session

    - by nccsbim071
    hi, i have a website where i provicde a link. On clicking the link a controller action method is called to generate a zip file after creation of zip file is done, i show the link to download the zip file by replacing the link to create a zip with the link to download the zip. the problem is that after zip file creation is over and link is shown, when user clicks on the link to download the zip file, they are sent to login. After providing correct credentials in the login page they are prompted to download the zip file. they sould not be sent to the login page. In the action to generate zip file i haven't abondoned the session or haven't not done anything that abondons the session. the user should not be sen't to login page after successful creation of zip file user should be able to download the file without login. i search internet on this problem, but i did not find any solution. In one of the blog written by hanselman i found this statement that creates the problem with the session: Is some other thing like an Ajax call or IE's Content Advisor simultaneously hitting the default page or login page and causing a race condition that calls Session.Abandon? (It's happened before!) so i thought there might be some problem with ajax call that causes the session to expire, but i don't know what is happening? any help please thanks

  • 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

  • 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?

  • 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.

  • 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.

  • 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.

  • 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

  • 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?

  • 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?

  • 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.
