how can use $(this).e.preventdefault() ? what want / need on window resize <a> should behave differently. in fiddle example if window width smaller 710 href should not triggered. there javascript function toggling subnav . if window wider 710px, want href work "normally". now setting example i've seen event firing multiple times. how can if fires once? also, there better way achieve want? please resize window in jsfiddle before clicking! fiddle here $( window ).resize(function() { var ww = $(window).width(); $('.windowwidth span').html(ww); if(ww < 710) { $('nav ul.nav > li > a').on('click',function(e){ e.preventdefault(); alert("here"); }); } else { $('nav ul.nav > li > a').on('click',function(e){ alert("there"); }); } }); you need check window width within click handler instead...

i have questions table , answers table has 4 8 answers connected 1 question. when want list of questions , answers, use following code: select q.questionid, q.question, a.answer question q inner join answer on q.questionid=a.questionid; this gives me 1 row each answer question being repeated on each row. however, want 1 row per question answers in separate columns. if possible, i'd limit 4 answers. if there more 4, rest should ignored. not important. the 4 answer columns named "correct", "wrong1", "wrong2" , "wrong3". first 1 in table (with lowest answerid) correct one. thank help! select q.questionid, q.question, case <some field> when <condition> a.answer end correct, case <some field2> when <condition2> a.answer end wrong1 ... question q inner join answer on q.questionid=a.questionid group q.questionid you can group question , define conditioned fields "correct...

i use java redis client "jedis". when getting sorted set using zrange example, client specifies returns set definition has no oredering guarantee. this old question mentions problem have found no reference whether resolved. can , know order preserved? set<string> results = jediscli.zrange(key, start, end); myobject[] requestedorderedobjects = new myobject[results.size]; int = 0; foreach(string result: results) { requestedorderedobjects[i++] = myobject.loadfromstring(result); } return requestedorderedobjects; thank help. order preserved, check type of set jedis returns: indeed sortedset , ordered. right: api doesn't give hint ordered, should not afraid: works fine, or apps have incredible bugs.

does offer blocks poll or vice versa ? meaning , can producer offer , @ same time consumer trying poll ? or if producer offering , queue blocks till done ? object a while (true){ inputqueue.offer(newpartlist); } object b while (true){ inputqueue.poll(newpartlist); } no, not. use linkedblockingdeque instead. remember use methods blockingdequeue or blockingqueue interfaces values. these methods implemented blocking. update neither offer nor poll methods blocking. in linked interfaces put* , take* methods implemented blocking. put blocks long queue full, take blocks if queue empty. now see asking else. in linkedblockingdeque calling offer blocks poll , because implementation has inernal lock synchronizing access. in concurrentlinkedqueue's javadoc explicitly stated, that: this implementation employs efficient "wait-free" algorithm based on 1 described in simple, fast, , practical non-blocking , blocking concurrent q...
