Mind Blowing Facts

i have simple text file contains list of folders on ftp servers. each line separate folder. each folder contains couple of thousand images. want connect each folder, store files inside foder in sequencefile , remove folder ftp server. have written simple pig udf this. here is: dirs = load '/var/location.txt' using pigstorage(); results = foreach dirs generate download_whole_folder_into_single_sequence_file($0); /* don't need results bag. dummy bag */ the problem i'm not sure if each line of input processed in separate mapper. input file not huge file couple of hundred lines. if pure map/reduce use nlineinputformat , process each line in separate mapper . how can achieve same thing in pig? pig lets write own load functions , let specify inputformat you'll using. write own. that said, job described sounds involve single map-reduce step. since using pig wouldn't reduce complexity in case, , you'd have write custom code use pig, i'd sug

i utilizing hashset finding maximum number of duplicates of value in sorted integer array. algorithm doesn't seem work, not returning desired results. set variables storing number of duplicates found (0), , maximum number of duplicates (0). set hashset stores unique values of array. sort array ready comparison. loop through each value of array if hashset of unique values contains current value: increment duplicate count if currentvalue not equal previous value: if duplicatecount greater maximum count: maximumcount becomes duplicatecount reset duplicatecount 0 java code : hashset<integer> uniquevalues = new hashset<integer>(valuesequencelist); int duplicatecount = 0; int maxcount = 0; arrays.sort(valuesequence); (int = 0; < valuesequence.length; i++) { if (uniquevalues.contains(valuesequence[i])) { duplicatecount++; } if (i > 0 && valuesequence[i] != valuesequence[i-1]

a filemaker script calls 'net use delete x:' command, return value '?'. knows mean? i suppose, using "send event" run "net use delete". more cmd usage filemaker. command should disconnect shared resource on network. '?' mean error filemaker not recognise. if should, ignore it. if not have check if connected resource , if network resource called correct name when disconnect. check permissions. best way debug make sure can run same commands in cmd.

this question has answer here: is possible run script in context of webpage, before of webpage's scripts run, using chrome extension? 1 answer i'm working on chrome extension add features existing page. that, need add script page as possible !! (no, cannot run content script starts before everything, need particular script inserted into dom ) (why? because page loads everythin using ajax calls, , need able perform operations before calls) so intent add script sooner can after head of document appears. i'm looking @ mutationsobserver , , seems job. how can check if node addednodes collection head??? since looks maybe provided answer actual problem, i'll post answer. you can use chrome plug-in api directly intercept ajax requests using this: https://developer.chrome.com/extensions/webrequest

i'm trying simplify fractions in binary code checks if value even: int is_even(floatlet value){ if(value & 1) return 0; return 1; } and while loop keeps bit shifting until value odd. while(is_even(numerator) && is_even(denomexp)){ numerator >>= 1; denomexp <<= 1; } the while loop goes on infinite loop. i'm wondering why? we've done test , is_even function works fine. thanks! your loop incorrect: should shifting demonexp right too. runs indefinitely numerator=0 , denomexp . if numerator , denomexp integer types, , number fraction numerator/denomexp , can fix code way: while (numerator && is_even(numerator) && is_even(denomexp)) { numerator >>= 1; denomexp >>= 1; } conversely, if denomexp power of 2 divide numerator, should increment instead, , maybe test overflow: while (numerator && is_even(numerator)) { numerator >>= 1; denomexp += 1; } you must pos
