• How do web crawlers affect site statistics?

  - by LM

  What are ways in which web crawlers (both from search engines and non-search engines) could affect site statistics (e.g., when doing AB-testing different page variations)? And what are ways to take care of these problems? For example: Do a lot of people writing web crawlers often delete their cookies and mask their IPs, so that web crawlers often show up as different users each time they crawl the site? What are heuristics to use to recognize that something is a bot? (I'm guessing any sophisticated enough bot can be indistinguishable from a real user, if it wants to -- is this correct?)

• Making a DataSet from another DataSet

  - by M.H

  Hi folks I have a client-server project (small project for companies in C#) and the server has a DataSet with some tables (there is no Database for some reasons so we save the DataSet as an XML file). when the clients connect to the server, the server should send some informations to the client depends on his privileges and some clients must add to or Delete from the DataSet in the server. I am thinking in Making a new small DataSet and sending it to the client (as xml) but I don't know how to generate a new DataSet with specific tables and rows (I tried to use Linq to DataSet but nothing worked). My Questions is how can I do that and is this a good solution to send informations to clients ? can you suggest a better scenario to send data to clients(I mean instead of making a new DataSet).

• How to fix Jersey POST request parameters warning?

  - by Brabster

  I'm building a very simple REST API using Jersey, and I've got a warning in my log files that I'm not sure about. WARNING: A servlet POST request, to the URI http://myserver/mycontext/myapi/users/12345?action=delete, contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected. My webapp only has the Jersey servlet defined, mapped to /myapi/* How can I stop these warnings?

• ASP.NET MVC POST Parameter into RouteData

  - by David Thomas Garcia

  I'm using jQuery to POST an Id to my route, for example: http://localhost:1234/Load/Delete with a POST Parameter Id = 1 I'm only using the default route in Global.asax.cs right now: routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); When I perform the POST, in my ActionFilter filterContext.RouteData.Values["Id"] is set to the default value of "". Ideally, I'd like it to use the POST Parameter value automatically if the URL comes up with "". I know it is posting properly because I can see the value of "1" in filterContext.HttpContext.Request.Params["Id"]. Is there a way to get RouteData to use a POST parameter as a fall back value?

• jquery ui tabs major style change

  - by Jonah

  I am using jquery UI tabs and I need to majorly change the styling on it. I need to rempve the background image, the borders, almost everything. I need it to look minimal, and not like it's self contained. What's the best way to do this? I need to use the default UI styling for the calendar widget however, which is on the same page. I've done a lot of research and everyone seems to point to the theme-roller. However, i do not just want to change the colors and border radii. I need to delete crap. theme-roller seems to be just change things like colors (not really useful for the real world) Is it even worth using jquery UI for my tabs?

• Proper way of deleting records with Codeigniter

  - by luckytaxi

  I came across another Stackoverflow post regarding Get vs Post and it made me think. With CI, my URL for deleting a record is http://domain.com/item/delete/100, which deletes record id 100 from my DB. The record_id is pulled via $this->uri->segment. In my model I do have a where clause that checks that the user is indeed the owner of that record. A user_id is stored in a session inside the DB. Is that good enough? My understanding is, POST should be used for one time modification for data and GET is for retrieving regards (e.g. viewing an item or permalink).

• Grails Shiro plugin : confirming my understanding

  - by bsreekanth

  I'm bit vague about how to start using the shiro plugin, after reading few documents. I decided against Nimble, as it comes with few tables and UI plugins. I setup shiro plugin with wildcard realm, with my own tables. I may use permission based (rather tan role based) access control as it scales well. Now, the steps for it. assign the permission string to the subject, and save it in the db check the permission through isPermitted, hasPermission (or relevant tags in GSP). Now, 1. when to use the accesscontrol through filter? 2. is there a closure injected into the controller where I can define the permission for the actions in it? 3. How do I create a typical access control scenario like only the creator of (something, a post etc) can delete it? thanks a lot.. Babu.

• Issue with CGEventTapCreate() call.

  - by Dheeraj

  Hi All, I'm trying to register for global key events using this code : void function() { CFMachPortRef keyUpEventTap = CGEventTapCreate(kCGHIDEventTap,kCGHeadInsertEventTap,kCGEventTapOptionListenOnly,CGEventMaskBit(kCGEventKeyUp),&keyUpCallback,NULL); CFRunLoopSourceRef keyUpRunLoopSourceRef = CFMachPortCreateRunLoopSource(NULL, keyUpEventTap, 0); CFRelease(keyUpEventTap); CFRunLoopAddSource(CFRunLoopGetCurrent(), keyUpRunLoopSourceRef, kCFRunLoopDefaultMode); CFRelease(keyUpRunLoopSourceRef); } The application crashes while executing CFMachPortCreateRunLoopSource() call. I think the crash is because of CGEventMaskBit(kCGEventKeyUp) when I create an event tap. But if I create event tap using CGEventTapCreate(kCGHIDEventTap,kCGHeadInsertEventTap,kCGEventTapOptionListenOnly,CGEventMaskBit(kCGEventFlagsChanged),&keyUpCallback,NULL), the application works fine. It does not crash. I'm getting callbacks when any modifier key is pressed. But I need to get callbacks for delete key pressed. Any ideas? Thanks, Dheeraj.

• How can I locate the indexpath of the UITableviewCell a certain button is in when I click that butto

  - by Jake

  I've added a button as an accessory view to uitableviewcell, and I when I press it, I'd like to be able to access the index path of the table view cell it's currently inside of so I can delete/modify the contents of that cell. Should I subclass UIbutton and add make it have it's own index path property? If so, do I need to implement any specific button methods in that subclass of will they automatically be loaded? Any help would be greatly appreciated. Sorry if this is a noobie question.

• Java Audit table logging, MySQL equivalent of CONTEXT_INFO.

  - by Julia

  Hi, I am looking for the MySQL equivalent of CONTEXT_INFO that is present in SQL Server. Or any other session variable like thing using which I can pass the username to the trigger. I am currently working on logging table data for audit. I need to pass the username of the logged in user to the delete trigger. Any ideas? We are deleting the rows from the table in a few cases and marking them as deleted in others. Any alternate solutions are welcome. I thought of using AOP but it could prove problematic when deleting a cascade. I want to look into Hibernate Interceptors, not sure at this point if that works. If I can find the MySQL equivalent of CONTEXT_INFO, my job is done and elegant as well. Thanks, Julia.

• List of dict in Python

  - by plalex

  Hi everybody, I've got a list of dict in Python: dico_cfg = {'name': entry_name, 'ip': entry_ip, 'vendor': combo_vendor, 'stream': combo_stream} self.list_cfg.append(dico_cfg) I append to my list a lot of dict in the same way. Now I would like to delete one dict and only one dict in this list? What is the best way to proceed? I've try with the index of the list, but when I remove a dict from the list, the index is modify, so after some random remove my index doesn't correspond anymore to the dict I want to remove in my list. I hope that is clear. Maybe I can add an "id" row in my dict, so I can ask to remove more preciously the dict I want. I'll ask to remove the dict where id is equal to the id's dict I want to remove. How can I do that? I hope I'm enough clear. Sorry but I'm a newbie in Python.

• Display nice error message when there is something wrong after ajax request jqgrid

Error code: 500 When i googled i found a event of the delGridRow function called errorTextFormat. Is this the event where i'm looking for? Can someone please give me an example of the implementation of this event? greetings niels

• Spring 3 JSON with MVC

  - by stevedbrown

  Is there a way to build Spring Web calls that consume and produce application/json formatted requests and responses respectively? Maybe this isn't Spring MVC, I'm not sure. I'm looking for Spring libraries that behave in a similar fashion to Jersey/JSON. The best case would be if there was an annotation that I could add to the Controller classes that would turn them into JSON service calls. A tutorial showing how to build Spring Web Services with JSON would be great. EDIT: I'm looking for an annotation based approach (similar to Jersey). EDIT2: Like Jersey, I am looking for REST support (POST,GET,DELETE,PUT). EDIT3: Most preferably, this will be the pom.xml entries and some information on using the spring-js with jackson Spring native version of things.

• Android image click in horizontal page view

• Building an XML editor in java and RichFaces

  - by Mark Lewis

  Hello I'm building an XML editor using the above technologies. In essence, I want to read in a whole XML file to a java object, and refer using this object to each element in the XML node tree (grouped into entries) to display the content locked, have separate padlocks for the user to click to 'unlock' an entry allow overwriting of the data, and to submit this entry. 'Add entry', 'Duplicate entry', 'Delete entry' are also functions I'd like to add. I already use dom4j and XPath to access areas of the XML file so some of the work in theory is already done. Given the above, I was going to use these two together with inplaceInputs to allow the user to edit the XML and JSF validators to check the data coming in. Is this the best way to approach this problem, or is there a more straightforward route than XPathing a whole record? I started looking at jaxb but I'm new at java and jsf but I've got the feeling I won't be by the end.. Thanks

• Is there a JS diff library against htmlstring just like google-diff-match-patch on plain text?

  - by Steve

  Currently I am using google-diff-match-patch to implement a real-time editing tool, which can synchronize texts between multiple users. Everything works great when operations are only plain texts, each user's operation(add/delete texts) could be diff-ed out by comparing to old text snapshot with the helper of google-diff. But when rich format texts(like bold/italic) are involved, google-diff not working well when comparing the htmlstring. The occurrence of character of < and > messed up the diff results, especially when bold/italic format are embedded within each other. Could anyone suggest a similar library like google-diff to diff htmlstrings? Or any suggestions can get my problem fixed with google-diff? I understood google-diff is designed for plain text, but really didn't find a better library than it so far, so it also works if a doable enhancement to google-diff can help. Thanks for any comments.

• DELETING doubled users (MySQL)

  - by vizzdoom

  Hi I have two tables. There are users informations from two sites: p_users p_users2 There are 3726 users in first and 13717 in second. Some users in p_users2 are in p_users. I want merge this two tables to the one big table - but rows with same usernames can't be doubled. How can I do this? I tried something like this: DELETE FROM p_users2 WHERE user_id IN ( select p.user_id from p_users p join p_users2 p2 on p.username=p2.username ) After that I should receive a table with unique usernames, which I want to export and import to the first one. But when I execute my query I got error: SQL Error (1093): You can't specify target table 'p_users2' for update in FROM clause. (MYSQL)

• What is a Perl regex for finding the first non-consecutively-repeating character in a string.

  - by DVK

  Your task, should you choose to accept it, is to write a Perl regular expression that for a given string, will return the first occurence of a character that is not consecutively duplicated. In other words, both preceded AND succeeded by characters different from itself (or start/end of string respectively). Example: IN: aabbcdecc OUT: c Please note that "not consecutively duplicated" does not mean "anywhere in the string". NOTE: it must be a pure regex expression. E.g. the solution that obviously comes to mind (clone the string, delete all the duplicates, and print the first remaining character) does not count, although it solves the problem. The question is inspired by my somewhat off-topic answer to this: http://stackoverflow.com/questions/2548606/perl-function-to-find-first-non-repeating-character-in-a-string
