• I want to style within JS

  - by 422

  Issue I have is I can use tags, but I would like to style particular words. Adding a class doesnt work, is it because I am within script dom ? Example: var config = [ { "name" : "tour_1", "bgcolor" : "black", "color" : "white", "position" : "BR", "text" : "Customize your user profile, it's easy. This is your shop window on <strong>here</strong> and <strong>there</strong>", "time" : 4000 } Instead of strong, I would like to apply class, like <p class="orange"> But it wont have it, any suggestions... please

• why number 9 in kill -9 command in unix?

  - by Alby

  I understand it's off topic, I couldn't find anywhere online and I was thinking maybe programming gurus in the community might know this. I usually use kill -9 pid to kill the job. I always wondered the origin of 9. I looked it up online, and it says "9 Means KILL signal that is not catchable or ignorable. In other words it would signal process (some running application) to quit immediately" (source: http://wiki.answers.com/Q/What_does_kill_-9_do_in_unix_in_its_entirety) But, why 9? and what about the other numbers? is there any historical significance or because of the architecture of Unix? Thanks!

• require.js - How can I set a version on required modules as part of the URL?

  - by Ovesh

  I am using require.js to require JS modules in my application. I need a way to bust client cache on new JS modules, by way of a different requested URL. i.e., if the file hello/there.js has already been cached on the client, I can change the file name to force the browser to get the new file. In other words, for the module hello/there, I'd like require.js to request the url hello/there___v1234___.js (the file name can look different, it's just an example), according to a version string which is accessible on the client. What is the best way to achieve that?

• mysql phpmyadmin, how to save date of birth that was attained through a form with the input type "se

  - by newbie-25

  Hello, I have a form which asks the user his or her date of birth. Its a drop down box since I use the select input type. The first drop down has Months, second has Days, the third has the Years. So the format should be Month(October), Day(25), Year(1990). In other words the months spell out the actual month and not simply the number representation of the month. However, I would like to save the Day and Year in their respective formats. How can I do this in phpMyAdmin? Should I use the DATE type? what should the value be? I just need to know how to correlate all of this in phpmyadmin, so I can save it properly. Thank you.

• How can I define the search scope by "this week" meaning Monday - Friday in Ruby on Rails?

  - by Angela

  This is an extension of an earlier question. I realized, what I really want is to go to a URL /report/thisweek and it will do a .find (or named_scope) across contact_emails.date_sent where date_sent is between MONDAY and FRIDAY of the week to which Date.today belongs. In other words, if today is THURSDAY, it will do a search for all emails MONDAY through THURSDAY of this week. Not sure if this is doable or makes sense, but I think that's what I'd ultimately am trying to do. Thanks!

• Returning string in java using 3 parameters

  - by user2905118

  Need to write a method describePerson() that takes 3 parameters, a String giving a person’s name, a boolean indicating their gender (true for female, false for male), and an integer giving their age. The method should return a String formatted as in the following examples: Lark is female. She is 2 years old. Or Jay is male. He is 1 year old. I am not sure how to write it correctly (my code): int describePerson(String name, boolean gender, int age) { String words=""; if(gender==true) return (name + "is "+gender+". "+"She is"+age+ "years old.); else return (name + "is "+gender+". "+"She is"+age+ "years old.); } The outcome "year" and "years" is also differs, but i don't know how to make it correct..

• How do I make a DIV stay at the top of the screen no matter ow far down the page my visitor scrolls?

  - by user1289863

  What I'm saying is, I have some extremely long pages on my website, which can make it annoying I've my visitors need to scroll to the top of the page to be able to navigate to another page. I'm not quite sure what I would call this but any Google search that contains the words 'DIV' and 'float' come up with completely unrelated results... What I'm looking to do is create a DIV that stays at the top of the Screen (not to be confused with the page) so that if the user is at the bottom of the page, they can still see the navigation bar just floating at the top of the screen. What I can think of is to position the DIV relative to the position of the screen but I don't know how to code this. I'm happy to use JavaScript (preferably in the form of jQuery), but if you know how to do this using CSS, I would favour your response. This might help: I know a little bit of jQuery and JavaScript and I know a good deal of CSS and HTML. Thanks in advance.

• In a C++ template, is it allowed to return an object with specific type parameters?

  - by nieldw

  When I've got a template with certain type parameters, is it allowed for a function to return an object of this same template, but with different types? In other words, is the following allowed? template<class edgeDecor, class vertexDecor, bool dir> Graph<edgeDecor,int,dir> Graph<edgeDecor,vertexDecor,dir>::Dijkstra(vertex s, bool print = false) const { /* Construct new Graph with apropriate decorators */ Graph<edgeDecor,int,dir> span = new Graph<edgeDecor,int,dir>(); /* ... */ return span; }; If this is not allowed, how can I accomplish the same kind of thing?

• How to version SQL Server schema using VS 2005?

  - by Mike

  I am new to C# programming and am coming to it most recently from working with Ruby on Rails. In RoR, I am used to being able to write schema migrations for the database. I would like to be able to do something similar for my C#/SQLServer projects. Does such a tool exist for the VS 2005 toolset? Would it be wise to use RoR migrations with SQL Server directly outside of VS 2005? In other words, I would handle all schema versioning using ActiveRecord:Migration from Rails but nothing else. If I do handle migrations outside of C# and VS 2005 with another tool, is RoR ActiveRecord:Migration the best thing to use or is there something which is a better fit?

• Assign RegEx submatches to variables or map (C++/C)

  - by Michael

  I need to extract the SAME type of information (e.g. First name, Last Name, Telephone, ...), from numerous different text sources (each with a different format & different order of the variables of interest). I want a function that does the extraction based on a regular expression and returns the result as DESCRIPTIVE variables. In other words, instead of returning each match result as submatch[0], submatch[1], submatch[2], ..., have it do EITHER of the following: 1.) return std::map so that the submatches can be accessed via: submatch["first_name"], submatch["last_name"], submatch["telephone"] 2.) return a variables with the submatches so that the submatches can be accessed via: submatch_first_name, submatch_last_name, submatch_telephone I can write a wrapper class around boost::regex to do #1, but I was hoping there would be a built-in or a more elegant way to do this in C++/Boost/STL/C.

• WebKit & Objective-C: how to parse a HTML string into a DOMDocument?

  - by Rinzwind

  How do you get a DOMDocument from a given HTML string using WebKit? In other words, what's the implementation for DOMDocumentFromHTML: for something like the following: NSString * htmlString = @"<html><body><p>Test</body></html>"; DOMDocument * document = [self DOMDocumentFromHTML: htmlString]; DOMNode * bodyNode = [[document getElementsByTagName: @"body"] item: 0]; // ... etc. This seems like it should be straightforward to do, yet I'm still having trouble figuring out how :( ...

• nothrow or exception ?

  - by Muggen

  I am a student and I have small knowledge on C++, which I try to expand. This is more of a philosophical question.. I am not trying to implement something. Since #include <new> //... T * t = new (std::nothrow) T(); if(t) { //... } //... Will hide the Exception, and since dealing with Exceptions is heavier compared to a simple if(t), why isn't the normal new T() not considered less good practice, considering we will have to use try-catch() to check if a simple allocation succeeded (and if we don't, just watch the program die)?? What are the benefits (if any) of the normal new allocation compared to using a nothrow new? Exception's overhead in that case is insignificant ? Also, Assume that an allocation fails (eg. no memory exists in the system). Is there anything the program can do in that situation, or just fail gracefully. There is no way to find free memory on the heap, when all is reserved, is there? Incase an allocation fails, and an std::bad_alloc is thrown, how can we assume that since there is not enough memory to allocate an object (Eg. a new int), there will be enough memory to store an exception ?? Thanks for your time. I hope the question is in line with the rules.

• 4D - is it any good?

  - by Pies

  Recently I found out that the company a friend of mine co-owns uses 4D, which I've never heard of before. They swear by it, but they're non-technical and what they say about it sounds like memorized marketing blurb. Unfortunately the 4D website also seems devoid of any actual information and is filled with words like "comprehensive", "solution", "platform" and "integrated" instead. Since that thing is rather expensive and uses a custom language that I don't have much inclination to learn just for one project, I'm cautious about it and I'm wondering if anyone had any experience with it? Would you recommend it? What is it good for? What competitive advantage would I gain by learning it as a programmer, or using it as a company?

• How does a cmdlet know when it really should call WriteVerbose()?

  - by Roman Kuzmin

  How does a cmdlet know when it really should call WriteVerbose(), WriteDebug() and etc.? Perhaps I miss something simple but I cannot find the answer. All cmdlet implementations I have seen so far just call WriteVerbose() without any hesitation. I know that it is correct to do so, but it is not effective. Performance suffers when verbose mode is off but a cmdlet still prepares data for WriteVerbose() call, that is, for nothing. In other words, in a cmdlet I would like to be able to: if (<VerboseMode>) { .... data preparation, sometimes expensive ... WriteVerbose(...); } But I don't know how to get this if (<VerboseMode>). Any ideas?

• Displaying a well formatted table

• Using the same cookie in two logins

  - by cer9ss

  Hi everyone, I need your help I've a MVC project that uses Jquery, where I've implemented a mechanism of "Remember Me" using cookies to save, clear and retrieve the login and password. I also have two screens where the user does the login. I want that both logins manipulate the same cookie. I've got to implement it, but I've realized that each one has a different behaviour. I mean, the cookie's value I save in the first login is not the same than the value that retrieves the second login (when I open it). In other words, if I mark "remind me" on the first login, it isn't reflected on the second login and viceversa. What can I do to make that both of them manipulate and read the same values from the same cookie? Is it possible? PS: For this situations I'm using the same web navigator: Firefox or IE. Thanks in advance

• I want to make a wrapped acces type for certain internals of one of classes and I have some performa

  - by Alex

  I am writing an abstract matrix class (and some concrete subclasses) for use on very differing hardwares/architectures, etc. and I want to write a row and column type that provides a transparent reference to the rows and columns of the matrix. However, I want to tune for performance, so I'd like this class to be essentially a compiler construct. In other words, I'm willing to sacrifice some dev time to making the overhead of these classes as small as possible. I assume all (small) methods would want to be virtual? Keep the structure small? Any other suggestions?

• get function address from name [.debug_info ??]

  - by user361190

  Hi, I was trying to write a small debug utility and for this I need to get the function/global variable address given its name. This is built-in debug utility, which means that the debug utility will run from within the code to be debugged or in plain words I cannot parse the executable file. Now is there a well-known way to do that ? The plan I have is to make the .debug_* sections to to be loaded into to memory [which I plan to do by a cheap trick like this in ld script] .data { *(.data) __sym_start = .; (debug_); __sym_end = .; } Now I have to parse the section to get the information I need, but I am not sure this is doable or is there issues with this - this is all just theory. But it also seems like too much of work :-) is there a simple way. Or if someone can tell upfront why my scheme will not work, it ill also be helpful. Thanks in Advance, Alex.

• Generic SQL builder .NET

  - by Patrick

  I'm looking for a way to write an SQL statement in C# targeting different providers. A typical example of SQL statements differentiating is the LIMIT in PostgreSQL vs. TOP in MSSQL. Is the only way to solve SQL-syntax like the two above to write if-statements depending on which provider the user selects or using try catch statements as flow control (LIMIT didn't work, I'll try TOP instead)? I've seen the LINQ Take method, but I'm wondering if one can do this without LINQ? In other words, does C# have some generic SQL Provider class that I have failed to find that can be used?

• Is there a (C#) library that will create feeds for Amazon Marketplace Web Services?

  - by Josh Kodroff

  Does anyone know of a library out there (preferably in C#) that will take classes and generate XML or flat files suitable for feeds to Amazon Marketplace Web Services? In other words, I'd like to do something like this: var feed = new AmazonProductFeed(); var list = new AmazonProductList(); var product1 = new AmazonProduct(); product1.Name = "Product 1"; list.Add(product1); var product2 = new AmazonProduct(); product2.Name = "Product 2"; list.Add(product2); feed.Products = list; // spits out XML compliant with Amazon's schema Console.Write(feed.ToXml()); It looks like the only code Amazon provides are wrappers for the web service itself and the directory-based transport utility (AMTU).

• extending Bash tab completion: how to handle paths / partial commands?

  - by Rawing

  I've added tab completion for my program to bash. It works quite well, but I don't know how to handle partial completion of words. Example: the user types ./program /home/user/De and presses TAB. This is then completed to ./program /home/user/Desktop/ , but there's now a trailing whitespace after 'Desktop/', which is not what I want. Basically, I need a way of preventing bash from adding whitespace after the completed word. I don't want to use bash's completion for paths.

• Should I pointer-cast from a private derived class to its base class?

  - by skydoor

  I found this from C++FAQ Generally, No. From a member function or friend of a privately derived class, the relationship to the base class is known, and the upward conversion from PrivatelyDer* to Base* (or PrivatelyDer& to Base&) is safe; no cast is needed or recommended. However users of PrivatelyDer should avoid this unsafe conversion, since it is based on a private decision of PrivatelyDer, and is subject to change without notice. How to understand the above words? I don't think the explanation is correct or accurate. I have a code like this class A{ }; class B: private A{ }; int main(){ B *b = new B(); A *a = new A(); a = b; //wrong a = (A*)b; //right }

• Where to find viterbi algorithm transition values for natural language processing?

  - by Rodrigo Salazar

  I just watched a video where they used Viterbi algorithm to determine whether certain words in a sentence are intended to be nouns/verbs/adjs etc, they used transition and emission probabilities, for example the probability of the word 'Time' being used as a verb is known (emission) and the probability of a noun leading onto a verb (transition). http://www.youtube.com/watch?v=O_q82UMtjoM&feature=relmfu (The video) How can I find a good dataset of transition and emission probabilities for this use-case? Or EVEN just a single example with all the probabilities displayed, I want to use realistic numbers in a demonstration.
