• Tag suggestion (not tag autocomplete)

  - by takeshin

  AJAX autocomplete is fairly simple to implement. However, I wonder how to handle smart tag suggestion like this on SO. To clarify the difference between autocomplete and suggestion: autocomplete: foo [foobar, foobaz] suggestion: foo [barfoo, foobar, foobaz], or even better, with 'did you mean' feature: [barfoo, foobar, foobaz, fobar, fobaz] I suppose I need some full text search in tags (all letters indexed, not just words). There would be no problem to do it witch regex or other patterns for limited number of tags (even client side). But how to implement this feature for big number of tags? Is there any particular reason (besides URL) the tags on SO are dash separated? What about Unicode characters in tags? I store the tags in the table with the following columns: id, tagname. My SQL query returns objects with following fields: id, tagname, count

• <div class="headerFst"> What is this?

  - by Jessica

  I have been attempting to remove a repeating header on all of my webpages for customization purposes, but have been unsuccessful finding what is causing this header repeat. I came across this code in the header, and after researching it, I can not find what its purpose is. Could this be my culprit for the repeating patterns? If not, please point me to the right direction. Here is the hmtl: <!--container--> <div id="container"> <div id="header"> <!--headerFst--> <div class="headerFst"> and here it is in look.css: div.headerFst { float:left; width:980px; padding-top:5px; } Thank you for viewing, and helping if possible.

• PHP front-end and Java back-end for a web app?

  - by Raydon

  I'm designing a web application. I was wondering if it was feasible to design a php front end (using some php framework e.g. CakePHP), which stores and retrieves data to display to the user. Then develop a java backend which listens to the database for changes, and depending on what was changed, performs some actions and updates the database. Any thoughts on this type of implementation would be appreciated.

• Becoming better at Vim

  - by Autopulated

  I've been using Vim for quite a long time, but I'm at a level where I use insert mode most of the time, and I still use the arrow keys to move around(!). I feel like I'm not getting the best out of my lovely editor, particularly regarding navigating (especially code), copy & pasting, and doing other manipulations of existing code. (though I am quite comfortable with complicated search/replace patterns). How should I go about learning more? What resources would people recommend?

• Use SQL to clone data in two tables that have a 1-1 relationship in each table

  - by AmoebaMan17

  Using MS SQL 2005, Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H I want to clone the data for GroupID == 1 into a new GroupID so that I result with the following: Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 5 | a | 23 | 3 6 | b | 24 | 3 7 | c | 25 | 3 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H 23 | H 24 | J 25 | K I've found some SQL clone patterns that allow me to clone data in the same table well... but as I start to deal with cloning data in two tables at the same time and then linking up the new rows correctly... that's just not something I feel like I have a good grasp of. I thought I could do some self-joins to deal with this, but I am worried in the cases where the non-key fields have the same data in multiple rows.

• C++ function dynamic data type definition

  - by user330352

  Hi all, in C++, when you define a function which takes one argument, you have to define the data type of that variable: void makeProccess(int request) However, I want to implement a function which takes different data types rather taking statically defined integer type. void makeProccess(anyType request) How can I design a proccess like this, any idea? Thanks.

• including .h files.

  - by Max

  Suppose I have two .h files: A.h and B.h. Moreover, A.h includes B.h itself: B.h - declares class B. class B { ... }; A.h - declares class A, which uses class B. #include B.h class A { void SomeFunction(const B& b); }; Now, I have some .cpp file, that uses both A and B classes (B class maybe used not only in A::SomeFunction(B)) What are the pluses to include both A.h and B.h (instead of only A.h) from the perspective of design-patterns and coding style.

• Are parallel calls to send/recv on the same socket valid?

  - by Jay

  Can we call send from one thread and recv from another on the same socket? Can we call multiple sends parallely from different threads on the same socket? I know that a good design should avoid this, but I am not clear how these system APIs will behave. I am unable to find a good documentation also for the same. Any pointers in the direction will be helpful.
