spring xd - SpringXD stream with Tail source reads ALL the lines in file again and again instead of just last n lines -

stream create --name tailtest --definition "tail --name=/users/name/documents/springxd/poc/input/try.txt --outputtype=text/plain --lines=1 |file --name=output --dir=/users/name/documents/springxd/poc/output --mode=append" --deploy

here see whether give --lines=1 or 2 or 0 there additional line entered in try.txt , saved, reading entire try.txt , dumping output file. 1 time again when add together line try.txt same reads entire file content rather lastly line , appends @ end of previous content in output, thought going wrong here, why tail not read lastly 1 (or specified n) lines set come in @ end of each line in input file?

it sounds replacing file when "and saved".

tail follows existing file and, yes, expects newline terminate new message.

i ran test , works fine...

xd:>stream create --name foo --definition "tail --lines=1 --name=/users/foo/documents/foo.txt | log" --deploy

logs lastly line of file,

23:15:58,925 info simpleasynctaskexecutor-1 sink.foo - sdsd

then

$ echo foo >> ~/documents/foo.txt

(which appends foo\n file)

results in

23:17:07,744 info simpleasynctaskexecutor-1 sink.foo - foo

the lines=1 applies existing file; if replace file new one, whole file used - log rotation.

How the IP address is recognized in the Internet in multicast? -

How the IP address is recognized in the Internet in multicast? -

i referring "broadcasting multiple recipients" oracle java tutorial:

both server , client utilize grouping identifier identify belong same group. grouping id duplicate in net (and goolged , said grouping identifier not need unique)

then how come client on other side of net can know belongs same grouping of server? give me links describe process?

if server mutlicasts sound streams, server b multicasts video streams. server uses grouping id 203.0.113.0:4446 server b happens uses grouping id 203.0.113.0:4446. how come clients in net knows differences? since server not know existence of server b @ all, not know how take unique grouping id, uniqueness in ip address.

it seems cross articles, talking adding mac address. in oracle java tutorial, coding client not mention mac address @ all.

i don't know mean 'reorganized' in title, client doesn't 'know belongs same grouping [as] server'. knows belongs grouping defined ip address. if there multiple hosts sending ip address receive of them.

couchdb - Status of a filtered pull replication with Couchbase Lite -

couchdb - Status of a filtered pull replication with Couchbase Lite -

how reliably check filtered pull replication has completed couchbase lite?

the replication status set stopped on completion or on fatal error. a alter listener fires on incoming changes can't used monitor connection status. you can find seq number of database not lastly seq of grouping of filtered changes.

the replication object lasterror property. guide says if set nil, there has not been error since replication started. check when see replication status go stopped.

that's not going work. passing users though on going escape entire string, it's going appear one value instead of list. anorm in play 2.3 allows pass lists parameters, here you'll have work around that.

php - Unable to retrieve serialized data from database -

i'm able update using serialize info database not able retrieve properly. echoing array when seek unserialize , retrieve database.

here how update using serialize:

$query ="update dashboard_widget_users set dashboard_widget_users.configuration='".serialize($tmp)."' dashboard_widget_users.dsnr_yw_user =12 , dashboard_widget_users.dsnr_dashboard_widget=1";

result:

this how tried unserialize() , retrieve database not getting output properly:

$config= unserialize($row['configuration']); echo $config['configuration'];

here code:

if($param['aktion'] == 'save-widget-vehicle') { $page['register-fahrzeuge'] = array( 1 => array( 'fahrzeug','aktiv',$page['script'],''), 0 => array( 'edit-fahrzeug','enabled',$page['script'],'',''), ); $opts = !empty($param['filteropts']) ? $param['filteropts'] : array(); $tmp = array(); foreach ($opts $opt) { $tmp[] = '"'.$opt.'"'; } $data = array(); $query ="update dashboard_widget_users w set w.configuration=\"".mysql_real_escape_string(serialize($tmp))."\" w.dsnr_yw_user =12 , w.dsnr_dashboard_widget=1"; $result = mysql_query($query, $myconnection); $html = '<table width="538" cellspacing="0" cellpadding="0" border="0"> <tr> <td> <div>'.createregister($page['register-news']).'</div> '.createmessage().' <div class="cont-liste-verlauf register"> <table id="fahrzeuge"> <tr> <td> </td> </tr> </table> </div> </td> </tr> </table>'; $return = array( 'status' => 1, 'html' => $html ); echo json_encode($return); die(); $param['aktion'] = 'get-widget-vehicle'; } if($param['aktion'] == 'get-widget-vehicle') { $page['register-fahrzeuge'] = array( 1 => array( 'fahrzeug','aktiv',$page['script'],''), 0 => array( 'edit-fahrzeug','enabled',$page['script'],'',''), ); $data = array(); $opts = !empty($param['filteropts']) ? $param['filteropts'] : array(); $tmp = array(); foreach ($opts $opt) { $tmp[] = '"'.$opt.'"'; } $query ='select dashboard_widget_users.configuration dashboard_widget_users inner bring together yw_user on dashboard_widget_users.dsnr_yw_user = yw_user.intern inner bring together dashboard_widget on dashboard_widget_users.dsnr_dashboard_widget = dashboard_widget.id dashboard_widget_users.dsnr_yw_user =12 , dashboard_widget.id =1'; $result = mysql_query($query, $myconnection); /*while ($row = mysql_fetch_assoc($result)) { if($row['name'] == 'anzahl_fahrzeuge_mit_und_ohne_bilder') { $sql = 'select * amo_bilder_live l left bring together afzdaten on l.dsnr_afzdaten = a.dsnr l.dsnr_afzdaten null'; $sql_result=mysql_query($sql); //get result... // $row['number'] = $result } $data[] = $row; }*/ $html = '<table width="538" cellspacing="0" cellpadding="0" border="0" > <tr> <td> <div>'.createregister($page['register-fahrzeuge']).'</div> '.createmessage().' <div class="cont-liste-verlauf register"> '; while ($row = mysql_fetch_assoc($result)) { $config= unserialize($row['configuration']); //$config= $row['configuration']; $html .= '<table id="fahrzeuge"> <a href="amo_fahrzeuge.php"> '. $config .'</a> </table>'; } $html .= '</div> </td> </tr> </table>'; $return = array( 'status' => 1, 'html' => $html ); echo json_encode($return); die(); }

you escape string depending on going utilize mysqli_real_escape_string() on value before putting into database - not when retrieving database:

$row=mysqli_fetch_assoc($result); $config=unserialize($row['config']);

How do I prevent Fiddler from blocking random websites? -

i using fiddler2 telerik , running weird issue programme blocking websites. here's illustration of randomly blocking www.slacker.com.

now when comes can close fiddler , refresh page , come without problem. however, since updated fiddler latest version it's started doing this:

why in world fiddler , how stop breaking random websites?

i found post on stackoverflow suggested using custom onbeforerequest rule this:

if (osession.fullurl == "http://slacker.com"){ osession["ui-hide"] = "do not want see"; }

i've tried adding custom rules did not seem prepare anything. have tried setting fiddler hear traffic ie since ie want see traffic from.

is there setting somewhere within fiddler prepare or need find different program?

edit: additional information: i'm running version v4.4.8.4 of fiddler.

this isn't fiddler.

the problem tcp/ip stack on computer, why chrome cannot connect site either.

are running firewall software? on managed corporate network, or home isp?

sorry, reply not straight related websphere, using datasources under jboss. since got no specific answers, thought help jboss experience...

we define datasource follow:

and works nicely...

in order utilize jee tag, must include xmlns:jee="http://www.springframework.org/schema/jee" <beans> declaration , http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.1.xsd xsi:schemalocation.

hope helps.

android - regCount error when instrumenting apk with soot -

i instrumenting apk file using soot. when add together next statement before running soot.main (without creating body transformer), regcount error. (the same error appears in different methods different apk files.)

scene.v().addbasicclass("myscheduler"); // packmanager.v().getpack("jtp").add(new transform("jtp.myinstrumenter", new mybodytransformer())); soot.main.main(args);

the error is:

thanks in advance.

my problem caused class code tried add. subtle point: utilize arraylist of "long"s, of methods adding/removing variables of type "long". although java performs boxing , had no problems executing java code, such discrepancy problematic in intermediate languages.

c++ - Function initialization with int& argument by int&& -

c++ - Function initialization with int& argument by int&& -

i have next code:

#include <type_traits> struct ttype { int = 0; bool operator() (int&) { homecoming true; } }; int main() { static_assert(std::is_same<decltype(std::declval<ttype>()(std::declval<int>())), bool>::value, "wtf?"); homecoming 0; }

if seek compile g++-4.8.2 receive error:

main.cpp:321:82: error: no match phone call ‘(jetplane) (int)’ static_assert(std::is_same<decltype(std::declval<jetplane>()(std::declval<int>())), bool>::value, "wtf?"); ^ main.cpp:265:8: note: candidate is: struct jetplane ^ main.cpp:279:7: note: bool jetplane::operator()(int&) bool operator() (int&) ^ main.cpp:279:7: note: no known conversion argument 1 ‘int’ ‘int&’

i don't understand note: no known conversion argument 1 ‘int’ ‘int&’ line. question is: why g++ interprets homecoming type of std::declval<int>() int , not line int&& though std::declval declaration looks like:

template< class t > typename std::add_rvalue_reference<t>::type declval();

i understand it's prohibited bind int&& int. why compiler doesn't print: note: no known conversion argument 1 ‘int’ ‘int&’ line. may don't understand , compiler changes somehow homecoming type of std::declval<int>() int&& on int in std::declval<ttype>()(std::declval<int>())?

thank help!

the problem is, cannot bind xvalue non-const lvalue reference.

let's @ expression

std::declval<int>()

the homecoming type of std::declval<int> indeed int&&. hence above look xvalue look of type int. note in c++ look never has reference type.

but operator

bool operator() (int&)

takes argument non-const lvalue referenece. if alter perameter type const int&, i.e.

bool operator() (const int&)

everything should work fine.

i putting jquery swipe navigation on project developed jquery mobile. can work no worries not dry implementation , know i'm going have issues updating in future. have series of html pages swipe navigate other html pages in same folder. here illustration of html code:

<div id="point2" class="tpb" data-role="page" data-title="baby section - talking point 2"> <header data-role="header" data-theme="f" data-position="fixed"> <a href="#" data-rel="back" data-theme="h" data-icon="arrow-l" data-direction="reverse">back</a> <a href="../activities.html" data-theme="h" data-icon="baby">activities</a> <h1>0-12 months</h1> </header> <div data-role="content" class="content" data-theme="a"> <h1>mother&rsquo;s voice</h1> <p>babies larn recognise mother&rsquo;s voice in utero. birth babe has preference voice on other sounds. babies begin larn difference between sounds not long after birth.</p> <p>talk babe , birth. utilize name, talk whatever doing , repeat words many times. babies need hear words lots of times before understand , utilize them.</p> <p><img src="../../img/baby/baby-tp2-mothers-voice.jpg" class="insert" /></p> </div> <script type="text/javascript"> $("#point2").on('swipeleft', function (event, ui) { if(event.handled !== true){ $.mobile.changepage('point3.html', {transition: "slide", reverse: false}, true, true); event.handled = true; } homecoming false; }); $("#point2").on('swiperight', function (event, ui) { if(event.handled !== true){ $.mobile.changepage('point1.html', {transition: "slide", reverse: true}, true, true); event.handled = true; } homecoming false; }); </script> </div>

now have tried follow jquery mobile documentation doing dry way , docs create no sense me @ all. appears though sample swap div has different background image. http://demos.jquerymobile.com/1.3.0/docs/examples/swipe/swipe-page.html

i confident can dry working if pages in single html file loads dom (single page app) working separate files? wondering if can set array pick sequential pages in folder , maintain order? js skills not great i'm looking working illustration pick apart can understand implementation. please allow me know if have implementations this. want dry!!

i've read in book way include paths root using $_server['document_root'].'subdirectory'. improve using '../php/db/connection.php'? difference?

it's not of thought have server-side executed files under document root. short whoops of misconfiguration may cost trade secrets or worse.

anyway, it's improve utilize "absolute" paths because referencing file may move around without need adjust paths.

i'm working on map editor accompany game i've been working on time; when effort load map game, however, shifted 2 or 3 tiles right.

a friend of mine suggested might addressing error, though i've never seen evidence of such.

here's loading function (it's called before main loop):

and map->init function (which called engine::init , sets map's dimensions new game):

void map::init(bool withactors) { tcodzip zip; if ( tcodsystem::fileexists("map.atm")) { zip.loadfromfile("map.atm"); //rng = new tcodrandom(seed, tcod_rng_cmwc); tiles=new tile[width*height]; map=new tcodmap(width,height); (int i=0; < width*height; i++) { tiles[i].canwalk=zip.getint(); //tcodbsp bsp(0,0,width,height); //bsp.splitrecursive(rng,8,room_max_size,room_max_size,1.5f,1.5f); //bsplistener listener(*this); //bsp.traverseinvertedlevelorder(&listener,(void *)withactors); } } }

android - Saving a counter in libGDX -

i developing game in libgx android. have counter on screen increment when touch something. in game can die, want save highest score player had. don't know begin with. new android game development. method when u die.

if (player.getbounds().overlaps(rock.getbounds()){ system.out.println("game over"); }

and here increment counter

if (player.getbounds().overlaps(food.getbounds()) { system.out.println("food"); counter++; }

thankyou

it sounds need preferences. provide platform independent way of saving little amounts of data. ideal stuff high scores.

call loadprefs() load storage , saveprefs() save them back.

public static preferences prefs; public static int counter; // variable want save //save shared preferences public static void saveprefs(){ prefs = gdx.app.getpreferences("game-prefs"); // name of prefs files prefs.putinteger("counter", counter); //counter counter wish save. "counter" name of varable saved in shared preferences prefs.flush(); //save preferences } //load shared preferences public static void loadprefs(){ prefs = gdx.app.getpreferences("game-prefs"); counter = prefs.getinteger("counter",0) //load counter, default 0 if not found }

sql - Issue with Oracle regex -

sql - Issue with Oracle regex -

select regexp_substr('select count(distinct empno), count(distinct deptno) emp', 'count\(distinct.*\)') dual;

for above query want output count(distinct empno), ".*" in above query taking lastly occurrence of ")" , not first occurrence.

can please tell how output want?

the * operator 'greedy' default. you're allowing characters between distinct , ), in quantity. , including first ) itself.

as eatÅpeach suggested, can create non-greedy ?:

a greedy operator matches many occurrences possible while allowing rest of match succeed. create operator nongreedy, follow nongreedy modifier (?)

so here, .*? instead of .*:

select regexp_substr( 'select count(distinct empno), count(distinct deptno) emp', 'count\(distinct.*?\)') dual;

or can specify should character except ) [^)]* instead of .*.

select regexp_substr( 'select count(distinct empno), count(distinct deptno) emp', 'count\(distinct[^)]*\)') dual;

android - Path on Canvas sometimes isn't visible -

i'm overriding imageview, , in ondraw method draw path on top of it. imageview view shown in listview.

on first render, image there, path isn't. if scroll down, images have paths, , when scroll up, first imageviews didn't show paths. know ondraw beingness called first imageviews, because set break in there.

the thing can think of maybe path beingness drawn before image? doesn't work way in code though. in fact, phone call setimagebitmap set image, in turn calls invalidate, in turn schedules ondraw. , ondraw calls super first.

disabling hardware acceleration has no effect.

well sense little dumb, figured out. here's reply in case makes same error did.

for reason, overriding onmeasure set dimensions of path i'll drawing. obviously, needs go in onlayout. first time view drawn it's size 0 when measured, path bunch of points on 0,0 coordinate. subsequent renders using recycled views, the listview, did have width , height when measured.

you can't utilize goto within loop , need delayed expansion implemented set, alter , use variable within loop.

that's not possible. "overlayimage" overlay on other objects.

why need that? can utilize "backgroundimage" instead?

thanks!

the reply question should provide sort of guidance on how sort of code you've provided (a long string of spreadsheet ternary if functions quite hard understand) in php more concise, , perhaps more readable.

i don't know if i'm plenty @ explaining sort of thing help you, think of import steps take in process to;

reformat code

putting each status on line of it's own, , each resulting output block on line of it's own, can hugely helpful understanding logic you've got. means can see patterns downwards through code.

group mutual logic

once code formatted nicely, , can perhaps see patterns emerging, should able grouping statements fewer blocks.

having taken these steps myself on code provided, function should provide same output given values of d6, k6, b9 , b11 getting in spreadsheet;

function calculatevalue($d6, $k6, $b9, $b11) { $modifiers = array( 'option_1' => array('horizontal' => 0.00515464, 'vertical' => 0.0064433), 'option_2' => array('horizontal' => 0.010417, 'vertical' => 0.005208), 'option_3' => array('horizontal' => 0.005208, 'vertical' => 0.010417), 'option_4' => array('horizontal' => 0.02083, 'vertical' => 0.03125), 'option_5' => array('horizontal' => 0.052083, 'vertical' => 0.0625), ); $x = $d6 + $k6; $y = $modifiers[$b9][$b11]; $sub = 0; if ($b9 == "option_2") { if ($b11 == "horizontal") { $sub += 0.25; } if ($d6 > 12) { $sub += 0.25; } } else if ($b9 == "option_3") { if ($b11 == "vertical") { $sub += 0.25; } if ($d6 > 12) { $sub += 0.25; } } homecoming $x - $sub + 1 - $y * $x; }

hopefully makes logic seem more readable , understandable well.

android - How to determine during the build which exactly version of dependency is used -

i want display exact versions of app's dependencies in "about" screen. in build.config i'm using wildcards compile 'com.google.guava:guava:16.0.+' dependencies, exact version used be, say, 16.0.1. there way dependencies listed actual versions and, example, set them buildconfig file can read them in app's runtime?

it sounds looking dependencyreport task project reports plugin

otherwise this:

task buildconfig << { new file("$builddir/buildconfig").withwriter { out -> configurations.runtime.resolvedconfiguration.resolvedartifacts.each { dep -> out.writeline(dep.moduleversion.id.tostring()) } } }

linux - git fetch - missing commits -

linux - git fetch - missing commits -

i running etckeeper on 2 different machines, boxa , boxb. os, etckeeper repository , all, on boxb copied boxa in january. in order apply setup changes made on boxa boxb, added repository on boxa remote repository on boxb intention of doing cherry picking, eg:

git remote add together boxa ssh://boxa/etc git fetch boxa git cherry-pick xxxx # never got far

the problem recent commits not available on boxa, commits until late february. far have tried:

doing git show 1 of missing commit numbers - not problem git log not showing commits.

copying total /etc on boxa boxb , adding/fetching via path - not issue somehow introduced ssh (to complicate things using script via git_ssh environment variable avoid creating root login).

git fsck on both repositories (no problems found).

running next command on copied version of both repositories (after doing git remote remove boxa on boxb , before readding):

git -c gc.reflogexpire=0 -c gc.reflogexpireunreachable=0 \ -c gc.rerereresolved=0 -c gc.rerereunresolved=0 -c gc.pruneexpire=now gc \ --aggressive

how can git fetch retrieve of commits?

so problem here turned out there detached head in repository on boxa after incomplete prepare of botched rebase. when happens output of git branch follows:

# git branch * (no branch) master

the fix create branch on boxa , merge it:

git branch temp git checkout master git merge temp git branch -d temp

after commits on branch master (or @ to the lowest degree thought branch master) available after doing git fetch.

i have skspritenode named ship, it's created :

ship = [skspritenode spritenodewithtexture:[sktexture texturewithimagenamed:@"spaceship"]]; ship.physicsbody = [skphysicsbody bodywithedgeloopfromrect:ship.frame]; ship.xscale = .5; ship.yscale = .5; ship.alpha = 1.0f; ship.position = cgpointmake(self.view.frame.size.width/2, self.view.frame.size.height/2); [self addchild:ship];

the ship shows fine on ios 8 simulator , on iphone 5 running ios 8, invisible on ios 7.

in update method set these logs :

nslog(@"ship : %@", ship); nslog(@"image : %@", ship.texture); nslog(@"alpha : %.2f", ship.alpha); nslog(@"parent : %@", ship.parent);

and output :

ship : <skspritenode> name:'(null)' texture:[<sktexture> 'spaceship' (100 x 100)] position:{160, 284} size:{25, 25} rotation:0.00 image : <sktexture> 'spaceship' (100 x 100) alpha : 1.00 parent : <skscene> name:'(null)' frame:{{0, 0}, {320, 568}}

everything there seems in order, , same log gets repeatedly called every update until ship, not visible @ all, flies off screen , code called remove , else.

without user interaction, on ios 8, happens ship appears in middle of screen, moves up, when exits frame game over. far can tell, exact same thing happening on ios 7, except ship invisible. frame's correct, responds user interaction, it's not showing up.

xcode 6 in beta right now. perchance issue. should seek running same code on xcode 5 ios 7 simulator or device.

also, can file bug study apple here.

for bean :

is bean autowired before :

reason i'm asking mybean set null. other beans have

@rendermapping("normal") public string rendernormal{ //mybean not null here }

mybean seems autowired correctly.

is @requestmapping("view") causing mybean not wired or beingness invoked before spring autowires mybean ? if how can configure spring wire mybean before entering method showview ?

update : missing <context:annotation-config /> in spring context file, question provides detail on utilize : difference between <context:annotation-config> vs <context:component-scan>

the lone @requestmapping annotation doesn't create class spring bean.

usually, @requestmapping goes hand-by-hand @controller annotation (which extends @component annotation) it's considered spring bean , (according javadoc)

the blurriness evident in png created todataurl well. thought going on here? don't think has re-sizing. i've tried setting ignoredimensions: true , other things.

another datapoint. if utilize raphael output text , utilize canvg, not blurry wrong font!

and here test.rect(0.5,0.5,50,50) suggested. still blurry:

so took me while, dawned on me. illustration images twice size code claims should be. you're on sort of hdpi device (retina macbook pro ect...) svg great because resolution independent, canvas on other hand not. issue you're seeing has how canvas renders. prepare this, need prep canvas drawing done @ resolution of screen.

http://jsbin.com/liquxiyi/3/edit?html,js,output

this jsbin illustration should great on screen.

the trick:

var cv = document.getelementbyid('box'); var ctx = cv.getcontext("2d"); // svg resolution independent. canvas not. need create our canvas // high resolution. // lets resolution of our device. var pixelratio = window.devicepixelratio || 1; // lets scale canvas , alter css width/height create high res. cv.style.width = cv.width +'px'; cv.style.height = cv.height +'px'; cv.width *= pixelratio; cv.height *= pixelratio; // high res need compensate our images can drawn //normal, scaling pixelratio. ctx.settransform(pixelratio,0,0,pixelratio,0,0); // lets draw box // or in case parsed svg ctx.strokerect(20.5,20.5,80,80); // lets convert dataurl var ur = cv.todataurl(); // result should canvas when using png (default) var result = document.getelementbyid('result'); result.src=ur; // need our image match resolution of canvas result.style.width = cv.style.width; result.style.height = cv.style.height;

this should explain issue you're having, , point in direction prepare it.

code styling black , white documents

i want utilize simple custom css code highlighting in knitted .rnw/.tex/.pdf documents. select few rules seem implemented upon knitting.

for moment focusing on colorless highlighting, consequently manipulate rules such text-decoration, font-weight, font-style , - grays - color; cf. theme "print" here. but, simplest examples, can few implemented, e.g., color , font-style; specifically, i've found font-weight nothing, nor text-decoration. e.g.:

.background { color:#f6f6f6; } ... .kwc {/* e.g., parameters */ font-weight:100; color:#8c8c8c; } .kwd {/* e.g., methods */ text-decoration:underline; } ... .com {/* comments */ font-style:italic; } ...

(the sets of 3 dots indicate css file contains more illustration above.)

with above in style sheet, in output pdf code block background , parameters colored accordingly , comments italicized, parameters not have font weight of 100 nor methods underlined.

is there sort of limitation rules custom knitr themes may use? else may problem here?

n.b.:

mac 10.9.3 knitr v1.6.3.

i have css in same directory rnw document , pass knitr in chunk @ origin of document via:

theme <- knit_theme$get('./my_css.css') knit_theme$set(theme)

c# to f# - Parameterless lambda expressions in F# -

c# to f# - Parameterless lambda expressions in F# -

i looking way define parameterless lambda expressions in f#, much next c# example.

var task = () => { int x = 3; dosomething(x); }

i tried following

let task = fun _ -> allow x = 3 dosomething x

it compiles gives me task : ('a -> unit) looking task : (unit -> unit)

the msdn documentation not talk this. missing here ?

it's just

let task = fun () -> // whatever need

you illustration be:

let task = fun () -> allow x = 3 dosomething(3)

assuming dosomething of type int -> unit - if returns else need

let task = fun () -> allow x = 3 dosomething(3) |> ignore

to type unit -> unit

remark: don't write let task = fun () -> ... let task() = ...

the thing missed: if write fun _ -> () saying want take parameter don't mind - f# take general (being named 'a here) - include unit! () value of type unit (more or less void c# ... true type in f#)

if utilize # instead of https://{{ provider }}.com/{{ nickname }} works great. why happening?

try following

p a(href='https://{{ provider }}.com/{{ nickname }}', target='_blank') {{ nickname }} | {{> chat_box_text }}

i believe shouldn't have double quotations have them singular ones, e.g. '

jQuery mouseleave not working -

jQuery mouseleave not working -

ok basically, ive got smaller div (overlay) thats hidden shows/hides when mouse hovers on main div (box). when mouse hovers , overlay div slides up, when mouse leaves box div overlay remains , not slide down.

css

.box {border:1px reddish solid; width:250px; height:230px; position:relative; overflow:hidden} .overlay {position:absolute; background-color:red; width:100%; height:50px; bottom:-60px}

html

<div class="box"><div class="overlay">content</div></div>

js

$('.box').hover(function(){ $('.overlay').animate({top:"180px"}); }); $('.box').mouseleave(function(){ $('.overlay').animate({bottom:"180px"}); });

your mouseleave should goto opposite value of initial animate:

$('.overlay').animate({top:"-180px"});

mysql_fetch_row() indexed array only.

either utilize mysql_fetch_array() or mysql_fetch_assoc()

check this: difference between mysql_fetch_array , mysql_fetch_row?

c++ - manual grayscale in opencv is too slow -

c++ - manual grayscale in opencv is too slow -

note: have manually don't suggest me utilize library function cvtcolor().

i'm new opencv , trying grayscale color image formula

(r,g,b) = (r,g,b)/((r+g+b)/3)

here method(c++) converting grayscale:

mat dst = src.clone(); (int i= 0; i<src.rows; ++i) { (int j = 0 ; j < src.cols; ++j) { vec3b myvec = dst.at<vec3b>(i,j); uchar temp = (myvec[0]+myvec[1]+myvec[2])/3; vec3b newpoint(temp,temp,temp); dst.at<vec3b>(i,j) = newpoint ; } }

because want grayscale video utilize method grayscale each of frame. slow in comparing using cvtcolor(src,dst,cv_rgb2gray). (i waitkey(1) not problem of waitkey)

i have 2 questions

i wonder if there way manually grayscale image fast cvtcolor. if not guy know how optimize above code grayscale video appears smoother. the above 1 approach grayscale. (r,g,b) = (r,g,b)/((r+g+b)/3) can guy tell me other approaches grayscale color image?

any reply appreciated. in advance.

i can tell ::at function slow.

i utilize struct , pointer here rgb example:

#pragma pack(push, 2) struct rgb { //members in "bgr" order! uchar blue; uchar green; uchar red; };

and acces pixels of image this:

rgb& rgb = image.ptr<rgb>(y)[x]; //y = row, x = col

change pixel values (for rgb image) this:

image.ptr<rgb>(y)[x].value[0] = 142; image.ptr<rgb>(y)[x].value[1] = 255; image.ptr<rgb>(y)[x].value[2] = 90;

you can translate grayscale problem pretty easy. thing is, fast because scanline of cv::mat image not split in memory pixels of 1 scanline next each other in memory.

excel - How do I read csv with large numbers (probably scientific notation) in R? -

excel - How do I read csv with large numbers (probably scientific notation) in R? -

i have 13-digit numbers in xls file , utilize excel generate csv file because need process in r. when r read csv file, cannot recognize big numbers. example, 1329100082670 appear 1.329e+12 in r , lost precision. i've tried format big numbers text in excel , save csv didn't work!

thanks in advance!

the numbers there, default r doesn't aways show them. see

> a<-1329100082670 > [1] 1.3291e+12 > dput(a) 1329100082670

the dput() shows digits retained if display on screen in scientific notation. can discourage r using scientific notation setting scipen option. like

options(scipen=999)

will turn off scientific notation. really, looks on screen shouldn't of import hopefully.

emacs - 'Symbol's function definition is void: nil' which symbol? -

emacs - 'Symbol's function definition is void: nil' which symbol? -

i'm getting next error when starting emacs: (as shown messages buffer):

c-font-lock-fontify-region: symbol's function definition void: nil

how track downwards causing error in function? debug-on-error true, still doesn't give more info here.

the symbol nil. not name function.

generally speaking, debug error, need set debug-on-error t , @ *backtrace* buffer. if no *backtrace* buffer appears (which case here), means caller of function signals error catches error. need chase code looking condition-case , disable it. luck :-(

looking @ c-font-lock-fontify-region definition in progmodes/cc-mode.el, see there

(funcall (default-value 'font-lock-fontify-region-function) new-beg new-end verbose)

which can cause error if (default-value 'font-lock-fontify-region-function) nil.

c++ - Casting unsigned byte array to array of Structs -

c++ - Casting unsigned byte array to array of Structs -

using c++ (gcc specifically, should have set sooner), i'm storing raw texture info in array of unsigned bytes, in rgba format, 32 bits per pixel (8 bits per color value alpha, on , forth...). thing is, want write function returns raw info array of colors, color struct defined following:

struct color { uint8 r; uint8 g; uint8 b; uint8 a; };

plus functions , whatnot, variables in struct. thinking since each color 4 bytes long, can somehow cast raw byte array color array 1/4 of original size (in "length" of array, not in absolute size). think reinterpret_cast looking for, cannot find after google search confirms 100% can convert array of structs instead of 1 struct.

so guess asking either confirm indeed possible reinterpret_cast, or if there different cast or way this. thanks.

edit: wording little weird, arbitrary illustration i'd somehow cast array of 16 unsigned bytes array of 4 colors.

edit: know it's kind of little late, cant seem find how cast little portion of array @ specific place single struct using reinterpret_cast, if possible, without copying smaller array , casting that. help problem appreciated.

as arbitrary illustration i'd somehow cast array of 16 unsigned bytes array of 4 colors.

like this:

#pragma pack(push, 1) struct color { uint8 r; uint8 g; uint8 b; uint8 a; }; #pragma pack(pop)

uint8 bytearray[16]; ... color *colorarray = reinterpret_cast<color*>(bytearray);

then can things this:

for (int idx = 0; idx < 4; ++idx) { color &c = colorarray[idx]; // utilize c.r, c.g, c.b, c.a needed... }

you have resources :categories defined under namespace :admin in routes.rb,so line in views/admins/categories/_form.html.erb

<%= form_for(@admin_category) |f| %>

should be

<%= form_for([:admin, @admin_category]) |f| %>

for more info,refer api

update

the sec error because of line

params.require(:admin_category).permit(:name, :slug, :description, :icon_xlarge, :icon_large, :icon_medium, :icon_small, :status)

it should be

params.require(:category).permit(:name, :slug, :description, :icon_xlarge, :icon_large, :icon_medium, :icon_small, :status)
