is possible have rowspan="2.5" ? using in creating timetable using html tables. have 1-hour interval , need show time 30-mins. how can it? thanks! no, it's not possible have decimals rowspan/colspan values. not does spec so (they must integers), wouldn't make sense. what can instead make each row 30 minutes instead of hour. then, double rowspan (5 instead of 2.5).

will please explain options hashes? working through ruby course testfirst.org. exercise 10 (temperature_object) requires knowledge of options hashes. options hash nice concept enabled feature of ruby parser. say, have method required arguments. may pass optional arguments. on time may add more optional arguments or remove old ones. keep method declaration clean , stable, can pass optional arguments in hash. such method this: def foo(arg1, arg2, opts = {}) opts.to_s # return string value of opts end so has 2 required values , last argument default value of hash. if don't have optional arguments pass, call this: foo(1, 2) # => "{}" if have optional, call this: foo(1, 2, {truncate: true, redirect_to: '/'}) # => "{:truncate=>true, :redirect_to=>\"/\"}" this code idiomatic ruby parser allows omit curly braces when passing hash last argument method: foo(1, 2, truncate: true, redirect_to: '/') # => &

how use bit masking make bits in number 1 if 0, , 0 if not? using unsigned variable: so, if have 0000-0000 , become 1111-1111 . if have 0101-0110 (or 0000-0001 , or 1111-1111 , etc), become 0000-0000 . is possible without using conditional? sure, it's possible: int y = 0xff; y = ~(y & 1 | y>>1 & 1 | y>>2 & 1 | ...) - 1 but unless academic exercise, shouldn't. if you're concerned performance, y = y != 0 faster. explanation: y & 1 takes first bit of number. y >> k shifts number right k bits, allowing bit y >> k & 1 . | them together, results in 1 if bit set or 0 if not. subtracting 1 gives 0 if bit set, , -1 if not. binary representation of -1 1111... shift: 1010 - y 1010 - y >> 0 101 - y >> 1 10 - y >> 2 1 - y >> 3 take first bit: 0 - y >> 0 & 1 1 - y >> 1 & 1 0 - y >> 3 & 1 1 - y >> 4 & 1 or them: 1 - 0

how can replace substring in nsmutableattributedstring without adding static range number? have label text: @"12 friends" , want replace 12 (number of friends) number (and use same attributes substring) once come server, , can not use below approach since number of digits unknown: /*wrong approach*/ nsmutableattributedstring *mutableattributedstring = [[nsmutableattributedstring alloc] initwithattributedstring:label.attributedtext]; [mutableattributedstring replacecharactersinrange:nsmakerange(0, 2) withstring:counter]; [label setattributedtext:mutableattributedstring]; if label read "x friends" why not use formatted string , pass in number of friends parameter. of course make whole thing variable localization, etc. basic idea this: nsinteger numberfromserver = ... nsstring *string = [nsstring stringwithformat:@"%d friend%@",numberfromserver,((numberfromserver != 1) ? @"s" : @"")]; nsmutableattributedstring *attribute

context i'm working dragonfly, python module. @ point, want speech recognized , outputted me. question i'm wondering if there way use dragonfly purely voice recognition without going through windows speech recognition (or alternative program). dragonfly meant "post-speech-recognition"? the examples i've seen , run open windows speech recognition. i've looked old speech recognition module - pyspeech, "borrows" windows speech recognition. should looking towards other modules? dragonfly uses shared recognizer, starts windows speech recognition. if modify dragonfly use inproc recognizer, windows speech recognition not start. (unfortunately, don't know enough python contribute fix.)

i want reference google spreadsheet using tabletop for data in d3 visualization. best solution can come this, know it's not quite right. window.onload = function() { init() }; var public_spreadsheet_url = 'https://docs.google.com/spreadsheet/pub?hl=en_us&hl=en_us&key=0amyzu_s7qhsmddnzuzrlyldnwtzclxdrmxlyqzvxsfe&output=html'; function init() { tabletop.init( { key: public_spreadsheet_url, callback: showinfo, simplesheet: true } ) } d3.json("showinfo", function(data) { console.log(data); }); the data comes array (see output below); , there no need apply d3.json . can start using array d3 visualization right away. window.onload = function() { init() }; var public_spreadsheet_url = "https://docs.google.com/spreadsheet/pub?hl=en_us&hl=en_us&key=0amyzu_s7qhsmddnzuzrlyldnwtzclxdrmxlyqzvxsfe&output=html"; function init() { tabletop.init( { key: public_spreadsheet_url, c

so registering event handlers in object's loaded event. tv.previewmousedown += new mousebuttoneventhandler(signalscrollviewer_previewmousedown); but had 2 questions. if loaded occurs twice , tries add event handler again there problems? how should handle unregistering event? automatically handle unregistering on destruction or need handle in event unloaded or something? yes cause subscription causes handler execute twice. can remove loaded handler inside loaded handler . msdn : loaded , unloaded might both raised on controls result of user-initiated system theme changes. theme change causes invalidation of control template , contained visual tree, in turn causes entire control unload , reload. therefore loaded cannot assumed occur when page first loaded through navigation page. if object gone cannot raise events, no need that. , handler not keep object alive (it's other way around).

i have odd problem in java. can solve solution seems inefficient. i have class, simplified is class zot { double edges[]; } the problem in many cases want instance , instance b share 1 of edge instances. in other words, instance may allocate edge[2] , want instance b share edge[2]. easy enough in can set instance b point @ instance's edge[2]. how can efficiently? if allocate edges[] in instance a, can assign b's instance point a. want allocate single edge (e.g. edge[2]) in , assign in b. in java, 1 cannot (as far know) allocate single member of array (as 1 can in c++). ideally, want allocate useful member , assign it. could, of course, allocate 4 members, assign ones need, set unwanted members null , let gc clean up, if there hundreds or thousands of instances seems clumsy. suggestions? you can declare , allocate double edges[] outside of both classes, pass array parameter in constructor both of instances want share it. in java arra

i have theme in attempting add plugin google analytics dashboard's "sparkline" custom posts column. make bit more clear, need add this: to columns here and that's it! i'm not well-versed php enough know how done. analytics data appears out-of-the-box on standard post types , other custom ones, if helps. i ask developer assistance, seems have disappeared. in advance, , i'm hoping 1 of quick, stupid situations easy answer can shared greenhorn :) hello, if want program solution of team-it not easy. should use google analytics api php. not possible describe @ small peace of text,but, may be, following links helpful , developer: https://developers.google.com/analytics/devguides/reporting/core/v3/coredevguide http://code.google.com/p/google-api-php-client/downloads/list https://developers.google.com/analytics/solutions/reporting

i building sort of modding system aspect of game in unity. allows common user write c# code used give access elements of game @ times, giving host of multiplayer server ability decide map load parameters etc. for of don't know, unity uses mono's equivalent of .net 2.0, question less specific unity , rather more towards c# , .net. i have assembly loading working, i've come point nice if give " user " access assemblies such system , unityengine . of course include dll 's in referenceassemblies property of compilerparameters , give them access possibly harmful functionality, such reflection , instantiate , destroy many others. how limit assembly references namespaces, such system.io , system.collections , without giving access system.reflection ? now posting of possibly relevant code: //excuse unityscript... find quicker things in //it's c# javascript syntax ;) //create compiler parameters var params:compilerparameters = new compilerparam

i have solrcloud set 12 shards 2 replicas each, divided on 6 servers (each server hosting 4 cores). solr version 4.3.1. due memory errors on 1 machine, 3 of 4 indexes became corrupted. unloaded cores, repaired indexes lucene checkindex tool, , added cores again. afterwards solrcloud hash range has been set null shards corrupt indexes (so new records can't indexed shards). know how set range on shards again? i ended fixing uploading new clusterstate.json zookeeper, using zookeeper cli tool, correct hash ranges set (they deducible since sorted shard name).
