i have 2 run configurations , run first, then, after done, run second. can in eclipse in single step? and, if so, can assign keyboard shortcut? there similar stack overflow question , though 1 different think can use same solution. looks like, according the eclipse page launch groups , can define sequence of launches in group. drawback must install cdt feature, it's not c/c++ applications.

so having bit of issue here deciding tools use solve problem. rather complex problem best describe it. at moment have relationship of values gathered , stored in hash. hash way of doing things can changed else think better. used hash keep relationship important. so like: key -> value 1456 -> 1 1532 -> 50 1892 -> 2 1092 -> 5 1487 -> 10 5641 -> 5 1234 -> 2 1687 -> 1 my goal here take values, , adjust them there no duplicates, , place adjusted values in appropriate relationship key. not want duplicate values deleted, want them changed in way there no duplicates anymore. (duplicates in example above are: 1 , 2) as side note here summary of few important things keep in mind situation: the relationship between key-value pairs (must know value key) not having duplicate values you cannot delete key-value pair, change value. the order of values lowest highest important normally have no trouble sorting array of integers, in case relationship o

i have 2 arrays comprising x,y vales y=f(x). provide function finds value of x corresponds either min or max sampled value of y. what efficient way select proper comparison operator before looping on values in arrays? for example, following: double findextremum(const double* x, const double* y, const unsigned int n, const bool ismin) { static std::less<double> lt; static std::greater<double> gt; std::binary_function<double,double,bool>& isbeyond = ismin ? lt : gt; double xm(*x), ym(*y); (unsigned int i=0; i<n; ++i, ++x, ++y) { if (isbeyond()(*y,ym)) { ym = *y; xm = *x; } } } unfortunately, base class std::binary_function not define virtual operator(). will compiler g++ 4.8 able optimize straight forward implementation? double findextremum(const double* x, const double* y, const unsigned int n, const bool ismin) { double xm(*x), ym(*y); (unsigned int

i have set of images want source change on mouseover. code works fine in except ie 7 , 8 - when hover on image changes broken image link. my code is: $(".socialicon").each(function() { $(this).find("img") .mouseover(function() { var src = $(this).attr("src").match(/[^\.]+/) + "hover.png"; $(this).attr("src", src); }) .mouseout(function() { var src = $(this).attr("src").replace("hover.png", ".png"); $(this).attr("src", src); }); }); would know if there have change have work in ie 7 , 8? you should debug on ie7&8 - value of $(this).attr("src") , src attribute has element after enter mouse on element? suppose, ie maybe returns absolute path image, " http://example.com/image.png " - in case regex not work. why not calling var src = $(this).attr("src").replace(&

i need advice on few design principles regarding crud operations in jsf project. a simple example: i have basic screen form submitted. in bean declare database connection in method , string object populate script. modify string data have been submitted in form. way taught it, i'm suspecting it's not based on solid principles. so decided start using prepared statements. seems bit better, still not perfect in mind. my question is: instead of writing new script each crud method, better perhaps create stored procedures instead, in mind looks neater code , perhaps has better readability. or there entirely different way of doing things? concerns have fragile oltp database. your jsf,s should redirect servlet calls service method, write business logic , call data access object execute required sql query. u should never use bean database connection... should use datasource data base connection. , yes simple preparedstatement enough do. should convert strings in se

following lines java docs of concurrenthashmap this class obeys same functional specification hashtable, , includes versions of methods corresponding each method of hashtable. however, though operations thread-safe, retrieval operations not entail locking, , there not support locking entire table in way prevents access. what meaning of statement though operations thread-safe from above paragraph? can explain example of put() or get() methods? the concurrenthashmap allows concurrent modification of map several threads without need block them. collections.synchronizedmap(map) creates blocking map degrade performance, albeit ensure consistency (if used properly). use second option if need ensure data consistency, , each thread needs have up-to-date view of map. use first if performance critical, , each thread inserts data map, reads happening less frequently.
