i writing java program. i have thousands of lists stored .txt files. each list contains thousands of words, set in alphabetical order. words in each list different (there no repetitions). i have search these lists, in order see whether query-word present in each list or not. how can take advantage of alphabetical order make search quicker? brute-force approach ( .equals() method) works takes several hours. thank in advance help! grateful if send me bits of code. java provides arrays.binarysearch(object[] array, object key) , collections.binarysearch(list<? extends comparable<? super t>> list, t key) methods improve results. they're not optimal solution, they're easy use , better brute force.

i have css3 transition, i've used cubic-bezier timing function works correctly on way in not on way out. have feeling what's happening runs cubic-bezier forward on animation out, , forwards again on way out, instead i'm trying have reverse cubic-bezier curve on way out. you can see when hover on box swings out fast , slows, , when release hover moves out super fast. here in action, not 100 percent sure how fix this. http://jsbin.com/apunaca/2/edit

i have following column family in cassandra storing time series data in small number of "wide" rows: create table data_bucket ( day_of_year int, minute_of_day int, event_id int, data ascii, primary key (data_of_year, minute_of_day, event_id) ) on cql shell, able run query such this: select * data_bucket day_of_year = 266 , minute_of_day = 244 , event_id in (4, 7, 11, 1990, 3433) essentially, fix value of first component of composite column name (minute_of_day) , want select non-contiguous set of columns based on distinct values of second component (event_id). since "in" relation interpreted equality relation, works fine. now question is, how accomplish same type of composite column slicing programmatically , without cql. far have tried python client pycassa , java client astyanax, without success. any thoughts welcome. edit: i'm adding describe output of column family seen through cassandra-cli. since looking thrift-based solutio...

i've been trying figure out how update global variable using ajax request. i'm stuck , need help. var markerarray = []; function jsonload(position){ //loads json , markers console.log("data getting jsoned"); $.getjson('json/***.json', function(result){ //gets json , parses results $.each(result, function(index, value){ //for each result, give index , value reps.push({value: value, index: index}); //push value @ array. ex. ian calderon }); try{ (var i=0; i<reps.length; i++){ if(reps[i].value.lat !== 'undefined' && reps[i].value.position === position){ var marker = (createmarker(reps[i].value.lat, reps[i].value.long, reps[i].index)); //only try create marker if there values updatearray(markerarray, marker); }}} catch(e){ } }); } i have tried doing this: function updatearray(array, obj){ $.ajax({ success : function(){ array.push(obj);...

i have c program seems performing ok unless call free on pointer. #include <stdio.h> #include <sys/types.h> #include <unistd.h> #include <stdlib.h> int main() { int i; gid_t *list; int num_groups = getgroups(0, null); list = malloc(num_groups * sizeof(list)); if (getgroups(num_groups, list) != -1) { (i = 0; < num_groups; i++) { printf("%d ", *list++); } } free(list); // free(): invalid size: 0x0000000002448040 *** return 0; } i've seen lots of similar posts refer invalid next size , not invalid size . i'm newbie when comes c - can't work out what's going on. you changing list *list++ , therefore free invalid. need free original pointer obtained malloc . as dasblinkenlight notes, you're not allocating memory right way. think going idiom, forgot *: list = malloc(num_groups * sizeof *list); ^ ...

we want replace custom npapi interface between browser based web application , client side daemon process. is there similar technology chrome's native client messaging in firefox? js-ctypes[1] closest alternative mozilla. https://developer.mozilla.org/en-us/docs/mozilla/js-ctypes i have c++ module compile binary executable native-messaging or library js-ctypes. difference between 2 native-messaging calls binary executable , performs stdin/stdout data exchange, , js-ctypes opens static/shared library (via dlopen) , calls exposed methods of library can return compatible data types[2] , optionally call passed javascript callback method.
