how touch file (i.e., update modification time without changing contents) in r? i'm looking cross-platform built-in (or packaged) equivalent of: system2("touch", file_name) see ?sys.setfiletime in case sys.setfiletime(path_to_file_or_directory, sys.time()) presumably job done: on unix-alike uses system call ‘utimes’ if available, otherwise ‘utimes’. on posix file system sets both last-access , modification times. on windows uses system call ‘setfiletime’ set ‘last write time’. windows file systems record time @ resolution of 2 seconds. although i'm not sure how reconcile " it uses system call ‘utimes’ if available, otherwise ‘utimes’ " meaningful statement.

i have application built on top of streaminsight 1.2 has several standing queries running calculations in user defined operators. 1 of calculations take relatively long time complete (a few seconds), , i'm seeing blocks other queries executing. i'm not familiar how streaminsight works i'm speculating queries run on single thread. there way have queries run in parallel? aside somehow putting queries on separate threads, there other things prevent 1 sporadically long running query blocking other queries? if calculation take few seconds , that's nature of and running standard edition, best thing can not block thread while calculation taking place. streaminsight doesn't have built-in ... it's your responsibility. streaminsight's perspective, udo taking time. doesn't know why is. , if thread blocked, can't run else until udo returns. a) validate running standard edition , b) if are, change udo it's non-blocking/async.

i'm writing shell script syncs files , want give users ability exclude files syncing creating .syncignore file similar git's .gitignore file. according gitignore documentation , , own experiments, these exclusion rules more complicated simple glob match. examples: if have foo in .gitignore file, exclude foo appearing anywhere in path (e.g. ./foo , ./bar/foo , , ./bar/foo/baz excluded) not partial matches of foo (e.g. ./foobar , ./bar/foobar/baz not excluded). if include slash, rule applied relative current directory. example, if have /foo in .gitignore file, exclude ./foo not ./bar/foo . you can include wildcards. example, foo* exclude ./foo , ./foobar , , ./bar/foobar/baz . is there easy way replicate exclusion rules .gitignore in shell script on os x? use rsync synchronize files. use existing include/exclude pattern support. put rules in .rsync-filter , pass -f flag make read patterns file. rsync man page just use git . make sure have...

i have classic asp site on visual studio 2012 development machine , have noticed strange behavior publish . a file called adovbs.inc exists in folder called debug within root of site. quite few files on (development) site reference without problem syntax: <!--#include file="../debug/adovbs.inc" --> after "successful" publish operation, note adovbs.inc file did not in-fact copied target location (on production machine) , hence get: include file '../debug/adovbs.inc' not found. i wonder if filetype .inc problem? server-side include files have filetypes of .asp in site. there "knob turn" somewhere in iis 7.5? after lots of frustration, copied file , pasted windows explorer , file found @ runtime. don't use vs publish website option classic asp site because there nothing compile, use copy website option instead, can find in website menu or right-click on website in solution explorer.

from node docs regarding creation of typed arrays buffers: the buffer's memory interpreted array, not byte array. is, new uint32array(new buffer([1,2,3,4])) creates 4-element uint32array elements [1,2,3,4] , not uint32array single element [0x1020304] or [0x4030201] . this contrasts plain javascript, creating typed array view arraybuffer uses arraybuffer's memory bytes. need behavior in node when operating on node buffers. i convert buffer arraybuffer, slow application. (i've tried many methods -- they're o(n) time.) (edit: fastest method i've found this , single memmove op , pretty fast, still has @ least momentary 2x memory consumption until reference original buffer released.) is there (fast/o(1)) way typed array buffer, using buffer's contents bytes instead of elements? (the needed typed array element size >1 byte, needless say.) as far know, not possible without making copy of data in memory. example new uint32array(ne...

i know how can gmm speaker model using openimaj library. org.openimaj.ml.gmm.gaussianmixturemodelem. have tried following gaussianmixturemodelem gmm = new gaussianmixturemodelem (default_number_components,gaussianmixturemodelem.covariancetype.diagonal); mixtureofgaussians mixture = gmm.estimate(data); boolean convergerd = gmm.hasconverged(); i true gaussianmixturemodelem has converged, lost go here. guidance appreciated. given comment, mixture.estimatelogprobability(point) should want (see http://www.openimaj.org/apidocs/org/openimaj/math/statistics/distribution/mixtureofgaussians.html#estimatelogprobability(double[]) ).
