• Splitting html string after so many words

  - by jimbo

  Hi all, I have a string that if it is longer than lets say 10 words, I want to split it into two parts. The second part will be included else-where after a 'more' link. The string will hold html tags too though. For an example the string could be: <p>This is just a test string with more words than the <strong>amount allow</strong> before split, blah blah blah</p> So in the case I would want: $string[0] // <p>This is just a test string with more words than</p>; $string[1] // <p>the <strong>amount allow</strong> before split, blah blah blah</p>; Thanks in advance

• Ruby on Rails in SpringSource tool suite?

  - by Martin Klosi

  I have been using Grails for some time now, but in school they are making us use Ruby on Rails. I have been trying to find an extension for ruby on rails for STS as there is for Grails, but I have failed. The only thing that comes close is a plugin so i can use ruby code in my Grails app using JRuby. I just want to make sure that a fully integrated extension DOESN'T exist. If that is the case, what would be the graphical IDE way of developing in ruby on rails, the same way one would use STS for Groovy on Grails development? (preferably free :) )

• Is it possible to add .NET code (sections) to a WordPress site?

  - by Jason

  Our shop is primarily .NET but because of the lack of any really good popular .NET CMS products, we have chosen to use WordPress (and Drupal at times) for our public facing sites. I realize this is highly subjective, but it is the conclusion we came to for our purposes. One could certainly make a case for DotNetNuke and others, but that is another conversation. I would like to know if I can integrate small components into WordPress sites, primarily to do simple forms (logon, lost password, contact us, change user settings, etc...) Can I do this with an iFrame or another method that I am not thinking about?

• Jenkins to not allow the same job to run concurrently on the same node?

  - by Marek Gimza

  I have 4 nodes and 2 jobs. Any node can run 2 jobs concurrently and any job can be executed concurrently. I want to be able to restrict running the same job concurrently on the same machine. For example: Jobs: J1 and J2 nodes: N1,N2,N3 and N4 I can run J1 and J2 on the same node at the same time. I can run J1 on N1 and N3 at the same time. BUT I do not want to run J1 and another build of J1 on the same node at the same time. I have tried "Locks and Latches", "Jenkins Exclusive Execution", "Exclusion Plugin" plugins, and these will work well when trying to coordinate different jobs. But my case is trying to manage different build-instances of the same job.

• how to display CFStringType? Like kABHomeLabel

  - by xiaozi

  I know that NSString and CFString are toll-bridge, they can convert in such a way. CFStringRef cfStr; NSString* anStr=(NSString*)cfStr; however,when I convert string in such a case when dealing addressbook NSString* homeLabel=(NSString*)kABWorkLabel; then homeLabel is "$!!$"; the other pre-defined CFStringRef in the addressbook property is the same. in my program,I want to get both the label and the label item's info. NSString* label=ABMultiValueCopyLabelAtIndex(multi,i); so how to correctly get the string of the label? Thanks!

• Will a source-removal sort always return a maximal cycle?

  - by Jason Baker

  I wrote a source-removal algorithm to sort some dependencies between tables in our database, and it turns out we have a cycle. For simplicity, let's say we have tables A, B, C, and D. The edges are like this: (A, B) (B, A) (B, C) (C, D) (D, A) As you can see, there are two cycles here. One is between A and B and another is between all four of them. Will this type of sort always choke on the largest cycle? Or is that not necessarily the case?

• SqlCeCommand ExecuteNonQuery performance issue

  - by Michael

  I've been asked to resolve an issue with a .Net/SqlServerCe application. Specifically, after repeated inserts against the db, performance becomes increasingly degraded. In one instance at ~200 rows, in another at ~1000 rows. In the latter case the code being used looks like this: Dim cm1 As System.Data.SqlServerCe.SqlCeCommand = cn1.CreateCommand cm1.CommandText = "INSERT INTO Table1 Values(?,?,?,?,?,?,?,?,?,?,?,?,?)" For j = 0 To ds.Tables(0).Rows.Count - 1 'this is 3110 For i = 0 To 12 cm1.Parameters(tbl(i, 0)).Value = Vals(j,i) 'values taken from a different db Next cm1.ExecuteNonQuery() Next The specifics aren't super important (like what 'tbl' is, etc) but rather whether or not this code should be expected to handle this number of inserts, or if the crawl I'm witnessing is to be expected.

• Selecting distinct values from mysql with largest timestamp

  - by user987048

  I am building a mail system. The inbox is only supposed to grab the last message (one with the highest time value) of a concatenation of user and sender, where the user or sender is the user ID. Here is the table structure: CREATE TABLE IF NOT EXISTS `mail` ( `user` int(11) NOT NULL, `sender` int(11) NOT NULL, `body` text NOT NULL, `new` enum('0','1') NOT NULL default '1', `time` int(11) NOT NULL, KEY `user` (`user`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; So, with a table with the following data: user sender new time ***************************************** 1 0 0 5 1 0 0 6 2 1 0 7 1 0 1 8 1 2 0 9 1 0 1 11 1 2 1 12 I want to select the following: WHERE USER OR SENDER = X (in this case, 1) user sender new time ***************************************** 2 1 0 7 1 2 0 9 1 0 1 11 How would I go about doing something like this?

• Validation of viewstate MAC failed in Safari

  - by Midhat

  Hi I have a web app using forms authentication. When I perform the following steps Let the login cookie expire Click on a link that requires a logged in user The user is redirected to the login page Click the browser back button The user is redirected to the login page again Log in using a valid username/password I get this exception Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. This case appears only in safari (windows and mac). The fundamental difference between safari and other browsers is that when we click the back button in step 4, safari shows the login page again, while the other browsers show the previous page the user was working on. Please help in this regard

• How to set up two models having a has_many association with each other

  - by daz13

  I'm looking for a suggestion on how to set up two models, Teacher and Subject. A Teacher can have many Subjects, and a Subject can have many Teachers. Another thing to consider in the relationship between the two models is that a Teacher can create a Subject and add other Teachers to the Subject. I think I'm solid on the basics of the set up for each model: for teacher.rb: has_many :subjects for subject.rb: has_many :teachers and the teachers table should have a subject_id column and the subject table should have a teacher_id column. What I'm not sure about is how to set up the views (and corresponding controller methods) to allow the addition of a Teacher to a Subject. Any suggestions (or links to examples) are greatly appreciated. I haven't been able to find anything on this exact case.

• Friendness and derived class

  - by ereOn

  Hi, Let's say I have the following class hierarchy: class Base { protected: virtual void foo() = 0; friend class Other; }; class Derived : public Base { protected: void foo() { /* Some implementation */ }; }; class Other { public: void bar() { Derived* a = new Derived(); a->foo(); // Compiler error: foo() is protected within this context }; }; I guess I could change it too a->Base::foo() but since foo() is pure virtual in the Base class, the call will result in calling Derived::foo() anyway. However, the compiler seems to refuse a->foo(). I guess it is logical, but I can't really understand why. Am I missing something ? Can't (shouldn't) it handle this special case ? Thank you.

• mysql PHP query question

  - by camran

  Ok, i have a problem here... I am sending values of drop down lists via ajax to this PHP file. Now I want to search a mysql database using these values, which I have managed to do, BUT, only if I set the values to something... Take a look: $query = "SELECT * FROM cars_db WHERE price BETWEEN '$cars_price_from' AND '$cars_price_to' AND year BETWEEN '$cars_year_from' AND '$cars_year_to' AND mileage BETWEEN '$cars_mileage_from' AND '$cars_mileage_to' AND gearbox = '$cars_gearbox' AND fuel = '$cars_fuel'"; now, what if the user doesnt select any "price_from" or "year_from"... The fields are only optional, so if the user doesnt enter any "price from" or "year from", then the user wants ALL cars to show... Do I have to write a query statement for each case or is there another way?

• Insert an element to std::set using constructor

  - by Dave17

  is it possible to insert a new element to std::set like in case of std::list for example: //insert one element named "string" to sublist of mylist std::list< std::list<string> > mylist; mylist.push_back(std::list<string>(1, "string")); Now, mylist has one element of type std::string in its sub-list of type std::list. How can you do the same in if std::set is the sub-set of std::list my list i.e std::list<std::set <string>> mylist; if you can't then why not?

• Data Validation for Random varying Phone Numbers

  - by baron

  I am storing phone numbers of varying lengths in my WPF (C#, VS 08) App. I store them as strings. My question is about my method AddNewPhoneNo(string phoneNo). In this method, I use Int.TryParse to validate the incoming number (i.e. not null, is numeric...). I've since realized this is probably not the best way to do this, because then I am limited to a number which is ± 2147483647. Definetly this is not always the case with phone numbers. What is a good, easy way to validate phone numbers? I guess the basic rules would be as follows: All numeric All positive Upto 25 chars (could be more, but this will to do for time being) Can't thing if theres any more rules at the moment, that's probably it.

• Acceptable name for extension method that accept null

  - by GaryX

  Hi, I really don't like to call String.IsNullOrEmpty(str). That makes me need to think "String" class first, then call it on the object "str". I like to call str.IsNullOrEmpty(), which doesn't need me to think "String" class. The problem is that extension method accept null instance to call on, which is not the usual case when you call a normal method. My question what do you think will be a convetion name for extension methods that accept null? For string, that is easy, "IsNullOrEmpty()" (anything that contains "IsNull") sounds good for me. For others, like GetDisplayName(), do we name it as "NullOrGetDisplayName" ?

• Map works, but throws a popup error at load complainig about wrong api key

  - by Filip

  Ok, I see a lot of people have this problem, but none answer I found either here or at stackoverflow. Problem: Map works super fine! But throws an error at load "This map needs a different api key... sign up at......" Already signed up, already got a key. On some forum post a guy told that in this case map loads twice, once with the wrong key, another with the right one. But Im sure my app loads it once and with the correct key. URL: http://ki.org.ua/ (it will redirect to /projects but I think that it aint a problem cuz i tested without redirection too) Thanks in advance for any suggestion or help.

• Simple logic in javascript

  - by Saurabh

  I have four variables of type integer - var tip_1, tip_2, tip_3, tip_4; The value of these variables are getting fill by some other logic which is always between 1 to 10. I need to maintain a hash with variable name as "key" and value as "value" by following these rules - The variable with MAX value should be the first element in the hash and so on. e.g. if tip_1 = 4, tip_2 = 1, tip_3 = 2, tip_4 = 10 then hash should be something like, Hash = {tip_4, 10} {tip_1, 4} {tip_3, 2} {tip_1, 1} In case of tie following order should be considered - tip_1 tip_2 tip_3 tip_4;

• Component not listening to MainApp's state change

  - by tag

  I don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE private function init(){ addEventListener(StateChangeEvent.CURRENT_STATE_CHANGE, function():void{ Alert.show("parent state changed"); }); } but as expected, it's reporting its own state changes not the main application's. I have 2 options: figure a way to tell it that I really mean the main application's state change not its own or configure the main application to dispatch a specific custom event that the component would listen for Any idea how I could do the first? or do I need the second option in this case?

• Javascript: setTimeout() - help needed

  - by ilkin

  Hi guys, I'm currently doing a highlighting function on a webpage and im using the jquery plugin for that. My code looks like this: var input = function() { var matchword = $('#searchbox').val(); if(matchword != "") { $('body').removeHighlight(); $('body').highlight($('#searchbox').val()); } } $(document).ready(function() { $('#searchbox').keyup(function() { setTimeout("input()", 2000); }); }); It works fine if there is not so large amount of data on the page. But in case of large amount of data on the page the whole process is slowing down which causes that inputbox is freezing untill the letter is hightlighted. So the typing is not smooth. I tryed to use a setTimeout but it seems doesnt help. Any ideas?

• [MATH]Project an axis to a plane

  - by Robert

  how do i project the X axis to a plane if the plane is defined by three points? see pic here: http://129.25.16.135:2080/v6.5/books/usb/graphics/iconventions-local-surfaces.png The default local 1-direction is the projection of the global x-axis onto the surface. If the global x-axis is within 0.1° of being normal to the surface, the local 1-direction is the projection of the global z-axis onto the surface. let's suppose that these points are: t1 = [-0.362879991531372, 0.357021987438202, -0.373737007379532] t2 = [-0.383525013923645, 0.371621012687683, -0.383549988269806] t3 = [-0.383534014225006, 0.34629300236702, -0.38544899225235] is the vector [0.78280971952246, -0.0307519963686645, 0.411184845614438] correct answer in this case? i've calculated the angle between the surf and x (1,0,0) is ~28°. and can you give the entire procedure for the calculation, because i'm just puzzled.
