do getelementsbyclassname (and similar functions getelementsbytagname , queryselectorall ) work same getelementbyid or return array of elements? the reason ask because trying change style of elements using getelementsbyclassname . see below. //doesn't work document.getelementsbyclassname('myelement').style.size = '100px'; //works document.getelementbyid('myidelement').style.size = '100px'; your getelementbyid() code works since ids have unique , function returns 1 element (or null if none found). however, getelementsbyclassname() , queryselectorall() , , other getelementsby* methods return array-like collection of elements. iterate on real array: var elems = document.getelementsbyclassname('myelement'); for(var = 0; < elems.length; i++) { elems[i].style.size = '100px'; } if prefer shorter, consider using jquery : $('.myelement').css('size', '100px');

what best way "bitwise and" on pixels in raster (maybe using "raster" package)? want check if sixth bit set. if given integer, use r's bitwand operator. 'and' 32 (has sixth bit set) , see if result 0 or otherwise. example: bitwand(96,32) # 32, has sixth bit set bitwand(192,32) # 0, not have sixth bit set i tried bitwand(myraster,32l) not work. thanks! r. for operations on each cell of raster, can use function calc of library raster . in case, be: r.test <- calc(myraster, fun = function(x) bitwand(x,32l))

i'm sending packets through multicast socket. i'm using max pratical size packets, 65 507 bytes (65,535 − 8 byte udp header − 20 byte ip header). however, results in 40-50% packet loss, if server , client in same computer. after testing out values, noticed can 0% packet loss if packet size less 10 000 bytes. why that? is limitation on laptop's network card? or problem udp itself? i'm using max pratical size packets, 65 507 bytes no aren't. 65,507 maximum theoretical size. sizes bigger impossible in ipv4. the maximum practical size 534 or thereabouts, whatever required never fragmented. fragmentation occurs increase probability of datagram loss same factor number of resulting fragments, there nothing in udp recover lost fragments.

i'm new netezza , need count number of ids have non-zero key. key transaction type, , want return count of ids have had transaction. want count of uids have non-zero key. my data: src uid key ... 118 3 ... 517 0 ... 517 1 ... 517 4 ... b 623 4 ... c 972 0 ... c 972 0 ... what want return: source uids uids_w_trans 2 2 b 1 1 c 1 0 here's code: select src source, count(distinct(uid)) uids, sum(case when key = 0 0 else 1) uids_w_trans database group uid, source what i'm getting source uids uids_w_trans 2 3 b 1 1 c 1 0 you can see query counting every non-zero key. i've tried number of variations on above query, nothing has gotten me closer. how can count 1 non-zero key per uid? i think looking conditional count(distinct) : select src source, count(distinct(uid)) uids, count(distinct case when key...

i using watson tone analyzer service. @ time of service creation, there 2 pricing plans - standard & premium. there difference in api or features of api if service created premium plan? have support compared standard plan? there no difference in actual api features between standard , premium plans. on pricing page states "watson premium plans offer higher level of security , isolation customers sensitive data requirements." means ibm offers 2 additional tiers of service on standard, shared saas offering - premium (a single-tenant virtual environment deployed on bluemix shared) , dedicated (a private cloud deployment built on bluemix dedicated). for pricing specifics, you'd have contact sales pricing page: https://www.ibm.com/watson/developercloud/tone-analyzer.html#pricing-block it comes down security requirements , weighing them against additional costs.
