i'm wondering if, in postgres, there downsides piggybacking fields index implicitly created primary key in order not have create more indices. this common technique in creating clustered indices in sql server. edit good article on postgres indexing. seems postgres indexing dynamics different sql server. no not possible. postgresql cannot "include" columns without making them "active" in index. currently postgresql not support index scans. included in upcoming 9.2 release though. but adding columns index don't need might impose performance penalty updates because non-indexed column more efficient update indexed column.

i new raw socket, , playing around ip header. noticed ip->ip_hl = sizeof(struct ip) >> 2 //works fine; ip->ip_hl = hton(sizeof(struct ip) >> 2) //will not work; what dont understand why not convert numbers network order instead of host order in case? what's general rule judge when use network order/host order? thanks htons 16-bit values. htonl 32-bit values. hton (no suffix), i'm not sure exists. the header length occupies 1 byte (actually part of 1 byte). don't need flip bytes right form. accordingly, there no macro htons or htonl 8-bit values.

i want scan folder of effects , check if each file listed row in mysql database of effects, , if isn't show un-tracked file. know efficient method achieve php? thank much. i think there's 1 way: glob directory, prepare 2 statements (a check , update) using pdo or mysqli , loop through files. if need on regular basis, should move tracked files different place track / check them.

i have hive table user id have ts column, timeseries, stored array. want maintain timeseries recentmost window. (a) how append new number end of each column table joined id? (b) how drop leading number? data in hive typically stored in hdfs. hdfs has limited append capabilities. if constant modification of data @ core of analytics systems, perhaps should consider using alternatives hbase or cassandra. however, if data updates small part of workflow, encourage continue using hive (in order make use of it's sql functionality) reconsider design storing these updates. a quick solution above problem have more 1 record per user id in table. each record have timeseries corresponding user id. when want last n analysis on timeseries, should select table using distribute by on user id column. custom reducer pick out last n (or less, if size of timeseries less n) timestamps , return them. harish butani did work on windowing functions in hive. can take @ his work , associated docume...

here have array undefined number of elements. tried print random element of array , cut it. here code. function rand(min, max){ return (math.floor(math.random() * (max - min + 1)) + min).tofixed(0); } $('#do').click(function(){ var count = chamarr.length; var num = 0; if (count == 1) { $('#output').html('nothing can found'); } else { num = rand(1,chamarr.length); $('#output').html(chamarr[num]); chamarr.splice(num,1); } }); when logged array cutted, saw ok, element not cut! my guess problem randnum method: function rand(min, max){ return (math.floor(math.random() * (max - min + 1)) + min).tofixed(0); } i believe give value in range [min, max] - inclusive @ both ends . (well, actually, give string version of value tofixed returns string, when use later it'll coerced number.) now you're calling this: num = rand(1,chamarr.length); so if array 6 elements long, you'll value in range [1, 6] . you'll try take chamarr[num] - , r...
