i have file love.txt loveyou.txt in directory useful ; want copy file directory /tmp . i use command: find ./useful/ -name "love*" | xargs cp /tmp/ but doesn't work, says: cp: target `./useful/loveyou.txt' not directory when use command: find ./useful/ -name "love*" | xargs -i cp {} /tmp/ it works fine, i want know why second works, , more usage of -i cp {} . xargs puts words coming standard input end of argument list of given command. first form therefore creates cp /tmp/ ./useful/love.txt ./useful/loveyou.txt which not work, because there more 2 arguments , last 1 not directory. the -i option tells xargs process 1 file @ time, though, replacing {} name, equivalent to cp ./useful/love.txt /tmp/ cp ./useful/loveyou.txt /tmp/ which works well.

i have form values aren't in database. wan't validation on them made validation rules using field names. somehow validation rules aren't being used. i tried set different rules. file names correct since $hasmany connection works. i hope can help! form: <?php echo $this->form->create('map'); echo $this->form->input('min_x'); echo $this->form->input('max_x'); echo $this->form->input('min_y'); echo $this->form->input('max_y'); echo $this->form->end('submit'); ?> validation rules: public $validate = array( 'min_x' => array( 'rule' => 'numeric', 'message' => 'please enter numeric value.' ), 'max_x' => array( 'rule' => 'numeric', 'message' => 'please enter numeric value.' ), 'min_y' => array( 'rule' => 'n

we offen use @echo "do..." letting print do... . can tell me mean of condition ? count=$(shell ls | wc -l ) then @count=$( shell ls | grep abc | wc -l ) what's mean of second? it disables printing command line being executed. output command still appears. see this previous question or see makefile reference.

i have problem thought break down simplest. there 2 applications on lamp stack, 1 php , java , same thing: run simple query: select * test php execution takes 30 ms in total java excution takes 230 ms in total query run on local mysql client takes 10-15 ms in total java takes ~200 ms every time establish connection db. understand php uses kind of built in connection pooling, therefor doesn't need establish new connection every time , takes 30 ms result of it. is same thing possible on java? far failed achieve that. tried use apache commons dbcp connection pooling, no change @ all, still takes same time connect database. update: separate question i'm trying make connection pooling work on java, asking code example: java mysql connetion pool not working you misunderstanding concept , purpose of connection pooling. connection pooling meant maintain (set of) connections on single (java virtual) machine (typically, application server). goal allow

i have application making uidatepicker , uitoolbar attached view. uitoolbar has animation set slide up. problem is. on iphone 4 toolbar needs finish animation @ lower position on iphone 5. how set height differently each device? you can distinguish iphone 5 iphone 4 this: if([[uidevice currentdevice] userinterfaceidiom] == uiuserinterfaceidiomphone && [uiscreen mainscreen].bounds.size.height == 568.0){ //is iphone 5 } else{ //is iphone 4 } then, set uitoolbar's frame appropriately each screen size. also, here's macro convenience (put in .pch file): #define is_4_inch_screen [[uidevice currentdevice] userinterfaceidiom] == uiuserinterfaceidiomphone && [uiscreen mainscreen].bounds.size.height == 568.0

i want check presence of dependent files before code compiled. doing following <available file="xx" property="isxxavailable"/> <available file="yy" property="isyyavailable"/> for compilation want check whether both properties true. go ahead compilation <target name="compile" depends="init" unless="isxxavailable" unless="isyyavailable"> is possible check both properties during compiling you can 'and' 2 'available' condtions single 1 : <condition property="files.available"> <and> <available file="xx"/> <available file="yy"/> </and> </condition> then can use condition in same way doing in target http://ant.apache.org/manual/tasks/condition.html

say have few links in navigation: ... {{#linkto 'projects.trending' tagname="li"}} <a href="#" {{bindattr href="view.href"}}> trending projects</a> {{/linkto}} {{#linkto 'projects.all' tagname="li"}} <a href="#" {{bindattr href="view.href"}}> projects</a> {{/linkto}} ... when click 1 of these links, fetch data via ajax , go route. takes while fetch data, i'd show spinner. have global spinner @ top of page. cool show spinner next navigation link clicked, user sees page loading. what best/easiest approach implement this? you put span next each navigation link that's hidden default, , contains spinner. onclick, show span. hide of them after ajax done.

i developing app browse(and more things, not relevant) youtube lists. whenever video, display it's corresponding image , show in listview (or gridview, again not relevant). here dilemma: better store images locally after downloaded, or download them every time want them showed, i.e: this._image = new bitmapimage(new uri("http://domain.com/content/someimage.jpg")); you're going want see youtube has on matter; i'm sure it's got regarding in developer api documentation note preferred approach it. that said, take general advice; when you're querying system, want limit how annoying are. now, youtube's not going notice load of 1 app, of course, it's still habit keep. speaking, i'd prefer split difference: cache image based on video id , hold x hours, if user pulls same video in search 20 times didn't request thumbnail 20 times well. that way keep result relevant updating image every day or 2 (assuming searched video again). e

for reason, php's strig_tags( ) function removing brackets tags explicitly allowed, when tags appear within attribute. example: <div data-contents="<p>hello!</p>"></div> becomes <div data-contents="phello!/p"></div> i know, know. isn't practice. regardless, ideas? as warnings on man page state: **because strip_tags() not validate html, partial or broken tags can result in removal of more text/data expected. if want embed html inside attribute, must encoded, e.g. should have &lt;p&gt;hello!&lt;/p&gt; instead. strip tags "dumb" , remove looks tag, regardless of tag occurs in text, or if result in broken page or not.

this question has been asked numerous times not find solution works. i developing application using fused location provider. in onconnected() method, requesting location updates , application logic initiated once location fix generated , onlocationchanged() called. (please refer code below). problem onlocationchanged() method never called on devices. use samsung tab 2 , samsung galaxy grand testing. code works fine on tab 2 not work on grand. not work, mean locationclient gets connected onlocationchanged() never called. earlier, used location manager getting location , in implementation, same problem occurred. so, tried implementing fused location provider still same problem. can me out issue? there missing here? public class mainactivity extends activity implements googleplayservicesclient.connectioncallbacks, onconnectionfailedlistener, locationlistener { locationclient locationclient; locationrequest lr; location loc1; static string address; @override protected

a friend , working on same .cs file @ same time , when there's merge conflict git points out there's conflict file isnt loaded usual "head" ">>>" stuff because .cs files binary files. added numerous things (*.cs text , on)- our .gitattributes file make git treat text file didnt work. thats when realized git diff other .cs files , not one. reason because in unicode encoding contains chinese characters. so how make git diff or merge files in utf-16 or utf-8 format? the furstrating thing if push, gitlab shows whats different. dont how git can diff on server not bash. i had similar problem *.rc files c++ project , found best way solve use git's smudge , clean filters store in repository utf-8, , convert utf-16 when writing working directory. this way git such diffs, merges or whatever work on utf8 text without issue, working copy have utf16, keep visual studio happy. to configure this, make sure you're using version of git

hi i'm trying parse large url's log using hive. there particular value want extract url (strategy=??) values can hyphenated, not always. i built sample query, returns nothing. what doing wrong? select regexp_extract('234=23234&werw=asdf&strategy=retargeting&asdf=fds23', '(strategy=)([-\w*]*)',2) vt; so value i'm expecting retargeting partial url string. 234=23234&werw=asdf&strategy= retargeting &asdf=fds23 any appreciated!!! i believe regex work you: strategy=((\w-?)+) here's regexr link: http://regexr.com?35sbl . after matching, group 1 contains value of strategy . note regex match number of hyphens in value. fails if hyphen first character (though, in opinion, leading hyphen not make value 'hyphenated'). from can tell, method didn't return because of way group 2 set up: have [-\w*] , says "match hyphen , number of alphanumeric characters (including 0)". rewrite [-?\w*]* , s

i've got table looks this: id (int, 9, unique key) --- item (int, 3) --- userid (int, 9) --- position (varchar, 12) now want run folling query: select count( * ) table position 'bag%' , userid = ".userid." the possible positions cases "bag0", "bag1", [...], "bag6" , unique - means there no userid has 2 items in bag2, example. but it's not unique - example 2 rows having "userid: 82378, positon: 'box1'" possible if try in()-clause doesn't change result. the "sending data"-time query 50ms. do have ideas how modify table query works faster? this query: select count( * ) table position 'bag%' , userid = ".userid."; this pretty simple query. way can speed using index. suggest composite index of table(userid, position) . mysql should optimize like because initial prefix constant. but, if want really, sure index gets used, can do: select count

i understand git reset updates index, whereas git checkout updates working copy. don't understand use case requires git reset accept argument reference , path? seems want use git checkout in case? this comes time when folks ask why can't git reset some-ref --hard -- some/path/to/file . real question why git reset accepts git reset some-ref -- some/path/to/file when have git checkout . never thought of till teaching difference between two. typically, if add file index, , realize want remove index, need: a reference (head) reset file index head (since head reference state nothing has been staged yet: commit) a file that is: git reset head -- a/file that "unstage" file. git reset moves head without affecting content (unless git reset --hard : mode working tree affected) git checkout modified working tree (and file content) git reset accepts ref , path because has three modes (soft, mixed , hard).

i not familiar html, css , javascript i using twitter bootstrap, i'd have section indicator in long page shows relative position of current view relative entire ver long scrollable page. the sample of want achieve in: http://global.tommy.com/int/en/collections/start i managed <ul> <li> , however, i'd animate arrow movement 1 <li> next <li> user scroll , down within page. managed scope out code <ul> <li> have no idea how animate movement... me point specific animation part or recommend javascript or css library that? missed twitter-bootstrap elements too, did not find far... thanks! edit: my code in jsfiddler, however, doesn't seem work in jsfiddler: the ul li code what wanted achieve animation on left side of tommy hilfiger's page when scroll , down, arrow keep track of section in adjusting arrow's position pointing specific section on li without more detail can't go specifics, can @ least sugges

i using arcsynthesis' tutorial learn modern 3d graphics programming, , while understanding of have run snag author calls "complex management code" can't understand how code works: struct instance { typedef glm::vec3(*offsetfunc)(float); offsetfunc calcoffset; glm::mat4 constructmatrix(float felapsedtime) { glm::mat4 themat(1.0f); themat[3] = glm::vec4(calcoffset(felapsedtime), 1.0f); return themat; } }; instance g_instancelist[] = { {stationaryoffset}, {ovaloffset}, {bottomcircleoffset}, }; i don't quite how function pointer getting set inside struct in g_instancelist[] don't syntactically how works , how g_instancelist used in next segment here: float felapsedtime = glutget(glut_elapsed_time) / 1000.0f; for(int iloop = 0; iloop < array_count(g_instancelist); iloop++) { instance &currinst = g_instancelist[iloop]; const glm::mat4 &transformmatrix = currins

looking @ gof patterns find similarities between state , stategy pattern rather striking. both swap out polymorphic classes modify behavior. else found same? what exact differences? the state , strategy patterns similar in sense both of them encapsulate behavior in separate objects , use composition delegate composed object implement behavior , both of them provide flexibility change behavior dynamically changing composed object @ run-time. there key differences : in state pattern, client knows nothing state objects. state changes happen transparently client. client calls methods on context, context oversees own state. because client not aware of state changes, appears client though context instantiated different class each time there change in behavior due state change. object appear change class official definition of pattern states. pattern built around well-defined series of state transitions. changing state key pattern's existence. even though strategy patte

i trying search program. don't know how search sentence in file. in c# can use linq , in java don't know. java loves difficult in both line-based , token-based scanning. heres example of line based scanning sentence: public static boolean scanfile(string sentence) { scanner linescan = new scanner(new file("filename.txt")); while (linescan.hasnextline()) { if (linescan.nextline().contains(sentence)) { return true; } } return false; } and heres example of token based scanning word: public static boolean scanfile(string word) { scanner linescan = new scanner(new file("filename.txt")); while (linescan.hasnextline()) { scanner tokenscan = new scanner(s.nextline()); while (tokenscan.hasnext()) { if (tokenscan.next().equals(word)) { return true; } } } return false; }
