i not sure start this, here want do: users have textfield need input few words. problem page use people different countries, , enter "weird" latin charaters like: ž, Ä, Ü, đ, Ť, Á etc. before saving base want convert them z, a, u, d, t, a... there way without making (i think there charaters cover): $string = str_replace(array('Č','Ä','Á','đ'), array('c','a','a','d'), $string); and, yes, know can save utf-8 in database, problem string later sent sms, , because of sms protocol nature, these "special" chars use more space in message regular english alphabet cahracters (i limited 120 chars, , if put "Ä" in message, take more 1 character place). first of all, still store original characters in utf-8 in database. can "translate" them ascii characters upon retrieval. because if, say, in future sms adds utf-8 support (or want use user data else), you'll have origina

i have class extending em::connection. inside class, check new entries in database, if there new entry, format data , send across tcp connection using send_data. after sending data, logs has done text file, updates database mark record sent. this program runs indefinitely , sends tcp updates @ frequencies driven sporadic user based activity generates database records. normally, can watch data pass across network using linux ngrep command. i having problem send_data command not sending data , not throwing errors. after gets in state, not send more data until restart program. makes issue worse because send_data not throw errors when occurs, program writes logs if worked , updates database record , marks sent. is there way check results of send_data command? if related far end not reading , read buffer maxing out, there anyway can check outbound buffer size?

back in october 2012, question posed ( d3.js - how automatically calculate arc lengths in radial dendrogram ) on how generate arcs in radial dendogram denote groups. user "wceo" posted elegant solution works well. however, possible change color of each arc individually, rather have them same color? trying... var color = d3.scale.category20(); ... and... var groupdata = svg.selectall("g.group") .data(nodes.filter(function(d) { return (d.key=='400' || d.key == '500' || d.key == '600' || d.key == 'current_missions' || d.key == 'future_missions') && d.children; })) .enter().append("group") .attr("class", "group") .attr("fill", function(d) { return color(d.group); }); ... returns each of 5 arcs same color.

i need implement map of counters (like map) in application. structure supposed accessed several threads. it looks concurrenthashmap<key, long> not proper solution, right? i thought concurrenthashmap<key, atomiclong> instead. but there problem - requests increment not spread evenly. few popular keys have 95% of increment requests data structure. as far understand lead concurrent access single atomiclong instances , there many locks should occur decrease efficiency. question 1: there better solution - perhaps, better data type instead of atomiclong , allows short accumulation of increments or this? question 2: want persist structure disk periodically (perhaps, every minute), , want persist "actual" state (with recent updates settled?) - straightforward way it? what makes think atomiclong uses locks internally? not true, it's built on cas operations. advice implement atomiclong , profile implementation later. if (and if) counter bot
