statistics - R-sq values, linear regression of several trends within one dataset -

i running sticky spot trying solve variance accounted trend several times within single info set.....

my info structured this

x <- read.table(text = " sta year    value   1968    457   1970    565   1972    489   1974    500   1976    700   1978    650   1980    659 b   1968    457 b   1970    565 b   1972    350 b   1974    544 b   1976    678 b   1978    650 b   1980    690 c   1968    457 c   1970    565 c   1972    500 c   1974    600 c   1976    678 c   1978    670 c   1980    750 " , header = t)

and trying homecoming this

sta r-sq n1 b n2 c n3

where n# corresponding r-squared value of locations info in original set....

i have tried

fit <- lm(value ~ year + sta, info = x)

to give model of yearly trend of value each individual station on years info available value, within master info set....

any help appreciated.... stumped on 1 , know familiarity r problem.

to r-squared value ~ year each grouping of sta, can take previous answer, modify , plug-in values:

# assuming x   info frame (make sure don't have hmisc loaded, interfere) models_x <- dlply(x, "sta", function(df)       summary(lm(value ~ year,   info = df)))  # extract r.squared values rsqds <- ldply(1:length(models_x), function(x) models_x[[x]]$r.squared) # give names rows , col rownames(rsqds) <- unique(x$sta) colnames(rsqds) <- "rsq" # have rsqds         rsq 0.6286064 b 0.5450413 c 0.8806604

edit: next mnel's suggestion here more efficient ways r-squared values nice table (no need add together row , col names):

# starting models_x above rsqds <- data.frame(rsq =sapply(models_x, '[[', 'r.squared'))  # starting original   info in x, great: rsqds  <- ddply(x, "sta", summarize, rsq = summary(lm(value ~ year))$r.squared)    sta       rsq 1   0.6286064 2   b 0.5450413 3   c 0.8806604

visual studio 2010 - What Are the Correct Web.Config Settings for the VS2010 F# Compiler? -

i've got aspx page this:

<%@ page language="f#" %> <!doctype html> <html> <head>       <title></title> </head> <body>    <%--  seek output "this test" 10 times --%>    <% = 1 10  %>       <p>this test</p>    </body> </html>

and web.config looks this:

<?xml version="1.0"?> <configuration>    <system.codedom>       <compilers>          <compiler language="f#;f#;fs;fsharp"             extension=".fs"             warninglevel="4"             type="microsoft.fsharp.compiler.codedom.fsharpaspnetcodeprovider,             fsharp.compiler.codedom, version=2.0.0.0,             culture=neutral,             publickeytoken=a19089b1c74d0809">             <provideroption name="compilerversion" value="v4.0" />             <provideroption name="warnaserror" value="false" />          </compiler>       </compilers>    </system.codedom>     <system.web>       <compilation debug="true" targetframework="4.0" />    </system.web> </configuration>

when run vs2010 webapp, error this: "the codedom provider type "microsoft.fsharp.compiler.codedom.fsharpaspnetcodeprovider, fsharp.compiler.codedom, version=2.0.0.0, culture=neutral, publickeytoken=a19089b1c74d0809" not located."

i've tried settings mentioned manojlds here, don't seem working me either. think because re-create of vs2010 pro has newer version of f# compiler, don't know how tell sure.

can help me understand right version settings should utilize in vs2010 web.config "compiler" , "provideroption" elements?

i have not tried this, configuration file looks right me - can check eversion of fsharp.compiler.codedom assembly installed in gac (by looking @ c:\windows\assembly)?

however, @ moment, not recommend using f# writing of aspx part of web page. works, won't smooth experience when mixing c# aspx or using razor templating engine (for asp.net mvc).

i think best way create server-side asp.net web applications in f# utilize f# code behind (in traditional webforms) or model , controller parts (in mvc). there number of templates , tutorials describe how this:

html - Show / Hide background image of div on hover -

i'm trying figure out if @ possible show , hide background image on div hover state. here's code: html

<div class="thumb">     <div class="text">         header<br>         sub-header<br><br>         date     </div> </div>  <div class="thumb">     <div class="text">         header<br>         sub-header<br><br>         date     </div> </div>  <div class="thumb">     <div class="text">         header<br>         sub-header<br><br>         date     </div> </div>

css

.thumb {     width: 400px;     height: 250px;     background-color: silver;     font-weight: bold;     background: url("http://www.imageurlhere.com") no-repeat 50% 50%;     -webkit-background-size: cover;     -moz-background-size: cover;     -o-background-size: cover;     background-size: cover; }  .text {     padding: 15px; }

so want alternate between background image , background color, when hover on div background image show, , on mouseout background image hidden , revert background colour (silver). found do-able via pseudo classes cms site images changed on fly, hence they'll have inserted via html:

style="background-image: url('insert url here')"

is @ possible hide , show background-image?

are against using javascript (or jquery)?

if not, have solution using .hover() function in jquery. said didn't want add together new classes new images. i'm proposing store urls in .thumb elements.

html:

<div class="thumb" data-hoverimage="http://placekitten.com/250/400">     <div class="text">header         <br>sub-header         <br>         <br>date</div> </div> <div class="thumb" data-hoverimage="http://placekitten.com/250/300">     <div class="text">header         <br>sub-header         <br>         <br>date</div> </div> <div class="thumb" data-hoverimage="http://placekitten.com/400/250">     <div class="text">header         <br>sub-header         <br>         <br>date</div> </div>

i stored each thumbnail's url in data-hoverimage attribute (it can whatever want).

then, using jquery, can utilize hover function. first function when cursor over, sec when cursor out.

$(".thumb").hover(function(){     var imgurl = $(this).data("hoverimage");     $(this).css("background-image", "url(" + imgurl + ")") }, function(){     $(this).css("background-image", ""); });

i have working model here: http://jsfiddle.net/auurq/

Finding the length of an array in C -

i'm trying find length of array of "header" structures defined (a header holds few informational int members, if relevant here). effort passing fl, pointer start of array, , idx, index value indicates proper fl_tails pointer is stationed @ end of array (in other/repetitive words, 'fl_tails[idx]` pointer end):

int arr_size(header* fl, int idx){    int cnt = 1; /* passed guaranteed have @  to the lowest degree 1 */     while(fl != fl_tails[idx]){     fl++;      cnt++;   } }

i thought advance fl pointer , generate count until end reached, goes infinite loop. i'm wondering if caused in function or elsewhere need find. when printed addresses of origin , end unsigned ints, seemed innocuous enough---things 16777216 , 16777344, respectively. maybe wrong understanding of header construction , size/effect on steps?

you want compare addresses, so:

while(fl != &fl_tails[idx]) ^

naudio - how to play more than one wav file in c#.net -

i need play more 1 wav file simultaneously (at same time). must have alternative volume command , stop, pause, , play.

i using naudio dll this. works fine times application goes crash.

this code:

_wavout = new waveout(); _wavreader = new wavefilereader(soundfilepath); _wavreader = (wavefilereader)waveformatconversionstream.createpcmstream(     _wavreader); _wavout.init(_wavreader); _wavout.play();

this stack trace get:

at naudio.wave.waveoutbuffer.writetowaveout() @ naudio.wave.waveoutbuffer.ondone() @ naudio.wave.waveout.callback(intptr, wavemessage, intptr, naudio.wave.waveheader, intptr)

if you're using soundplayer, impossible.

php - How to properly count a query in pdo -

i trying dynamically load more posts scheme

this code...

$stmt = "   select * `acmposting`    (`sender`='$thisid' , `posttype`='a')   or (`recip`='$thisid' , `sender`='$userid' , `posttype`='a')   or (`sender` in ($friendsarray) , `recip`='$thisid'  , `posttype`='a')   order `timesent` desc limit $startlimit,10";      if($stmtcount = $conn->query($stmt)){         if($stmtcount->fetchcolumn() > 0){             $result = acmposts($conn, $site, $userid, $stmt);             $jsonarray['a'] = $result;             $jsonarray['b'] = 'go';                      }else{             $jsonarray['a'] = '<div class="thisoutput" style="padding:12px;">there no more posts</div>';             $jsonarray['b'] = 'stop';         }     }

everything works fine until gets lastly set of posts aka if limit 100,10 there 105 posts in phone call won't phone call fetchcolumn().

i hope question makes sense. in advance help can give.

edit

how can determine when have reached limit , deed accordingly

PHP file doesn't rewrite -

i create site map, , create php file, generate mysql. alter host , have problem writing file. can't understand something. here example:

<?php  $xml = 'bla bla xml'; //... xml generating code $fp = fopen($_server['document_root'].'/my_site_map.xml', 'w');      if($fp)       echo 'we opened it';    else       echo 'we failed';     $fwrite=fwrite($fp, $xml, strlen($xml));     if($fwrite==false)       echo "another fail";     fclose($fp);     echo "we done";  ?>

the question is: file my_site_map.xml have permission 664 (rw-rw-r--), , can't utilize script if open php page browser, so, if seek i'll see: "we failed fail done"; if open through crontab , see log file, can see this: "we opened done". want main problem file isn't have been rewritten. why? , how can prepare this? thanks.

my server nginx not apache, didn't thought info valuable

well don't have plenty rep comment have answer.

i'm going take stab in dark , file owned user or root, not process running webserver. nor file owned grouping webserver process run under.

so either chown/chgrp file owned apache(?!) process running, e.g. chown apache file or set file have write permissions everyone, e.g. chmod 666 file

don't chmod 777 commented above unless it's executable file , want able run it. 1st solution improve practice giving read access file.

edit: in comment comments on original reply above, if file isn't executable don't give 7 permisions. 6 read/write , suitable text file opening write (even 2 if comes that).

edit 2: seek catching exceptions fopen function runs in seek grab block:

try {      $fp = fopen($_server['document_root'].'/my_site_map.xml', 'w');  }  grab (exception $e) {      echo "the error is" . $e->getmessage();  }

laravel - Persistant Register_Globals Error -

i transferred site 1 hosting company another. changed on started intermittently error saying:

directive 'register_globals' depreciated in php 5.3 , greater

its shared hosting have no access php.ini file turn off. i've tried disable using htaccess no luck.

if go cpanel , in php configuration says on, on old server said off. have spoken hosting company , off if in info.php, half true... local value off , master value on. on old server master , local both off.

the server running php version 5.3.13, if interested. i'm using framework laravel 3 hosting company said also: "the 1 way prepare disable in php completely, not sure if there other client using not work on shared hosting platform." guess isn't alternative turn off completely, don't see why not!

i have gone application/config/error.php , added

'ignore' => array(e_warning, e_notice, e_user_notice, e_deprecated, e_user_deprecated)`

but did not work @ graduated , volunteer project, i'm literally pull hair out give thanks in advance!

the way 100% sure - run follow php command within project

<?=phpinfo();?>

it give total dump of actual values php using.

search register_globals , see server thinks.

maybe time swtich hosts?

Calling and Passing Javascript parameters as part of a HTML5 data attribute -

based on solution cerbrus here;

passing function custom info attribute

is possible pass parameters part of custom attribute? like;

<div data-myattr="hello(foo)"></div>

why?

i mean, yes, if want regex match contents within parens, separated commas, , inject them. that's madness.

why not create sec data-attribute?

<div data-command="myfunction" data-params="one,two,three"></div>

and grab like:

var command = document.queryselector("[data-command]"),     vars = command.dataset.params.split(","),     funcname = command.dataset.command;   window[funcname](vars[0], vars[1], vars[2]);

or alternatively:

window[funcname].apply(undefined, vars);

audio - How do I filter out out-of-hearing-range data from PCM samples using C++? -

i have raw 16bit 48khz pcm data. need strip info out of range of human hearing.

for i'm doing sum of samples , dividing sample count calculate peak sound level, need cut down false positives.

i have big peak level time, speaking , other sounds can hear increasing levels little, need implement filtering. not familiar sound processing @ all, not using filtering because not understand how create it. current code looks this:

for(size_t = 0; < buffer.size(); i++) level += abs(buffer[i]); level /= buffer.size();

how can implement kind of filtering using c++?

use band pass filter.

a band-pass filter device passes frequencies within range , rejects (attenuates) frequencies outside range.

this sounds sort of filter looking for.

i had quick google search , found this thread discusses implementation in c++.

sql server - Create more then one column in a pivot table with one sql statement -

i need sort on date in pivot table project info same project number

the project looks this:

"project nr"   "task"                "task deadline"  "task type production" 123             pack                  1  apr 2013    pack 123             leave production      3  apr 2013    leave production 123             flight date           9  apr 2013    flight date

the "task type production" made ensure contents of field consistant can create 1 column in pivot table. there way display thes info in 3 columns this:

project nr ;  pack   ;  leave production ; flightdate      select  [taskdeadline] packed         msp_epmtask_userview  [task type production] = 'packed' select  [taskdeadline] leaveproduction         msp_epmtask_userview  [task type production] =  'leave production'  select  [taskdeadline] flightdate         msp_epmtask_userview  [task type production] =  'flight date'

thanks anne

this can done using aggregate function , case expression:

select  [project nr],     max(case when [task type production] = 'pack' [task deadline] end) pack,     max(case when [task type production] = 'leave production' [task deadline] end) [leave production],     max(case when [task type production] = 'flight date' [task deadline] end) [flight date] msp_epmtask_userview   grouping    [project nr]

see sql fiddle demo

if want utilize pivot function in sql server, query be:

select * (   select [project nr],[task deadline], [task type production]   msp_epmtask_userview  ) src pivot (   max([task deadline])   [task type production] in ([pack], [leave production],                                  [flight date]) ) piv

see sql fiddle demo.

finally can done using multiple joins table:

select t1.[project nr],   t1.[task deadline] pack,   t2.[task deadline] [leave production],   t3.[task deadline] [flight date] msp_epmtask_userview t1 left  bring together msp_epmtask_userview t2   on t1.[project nr] = t2.[project nr]   , t2.[task type production] = 'leave production' left  bring together msp_epmtask_userview  t3   on t1.[project nr] = t3.[project nr]   , t3.[task type production] = 'flight date' t1.[task type production] = 'pack'

see sql fiddle demo

the result of queries is:

| project nr |       pack | leave production | flight date | ------------------------------------------------------------ |        123 | 2013-04-01 |       2013-04-03 |  2013-04-09 |

i used initcomponent() method before setting setonitemclicklistener()

the forcefulness close error gone , app opens normally,

but next activity not opening or nil happens.when click on items. :(

as said tried different cases,still no success

              public void onitemclick(adapterview<?> parent, view v3,                 int position, long id) {               //setcontentview(r.layout.abc);             switch (position) {             case 0:                 intent myintent = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent);                 break;             case 1:                 intent myintent1 = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent1);                 break;             case 2:                 intent myintent2 = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent2);                 break;             case 3:                 intent myintent3 = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent3);                 break;             case 4:                 intent myintent4 = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent4);                 break;             case 5:                 intent myintent5 = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent5);                 break;             case 6:                 intent myintent6 = new intent(getapplicationcontext(),abc.class);                 startactivity(myintent6);                 break;              default:                 break;             }           }      });

you need phone call custom initcomponent() method before setting setonitemclicklistener()

public class cactivity extends activity  {   gridview gridview;      public void oncreate(bundle savedinstancestate)              {     super.oncreate(savedinstancestate);     setcontentview(r.layout.cactivity);     initcomponent();              gridview.setonitemclicklistener(new onitemclicklistener()             {               public void onitemclick(adapterview<?> parent, view v,                 int position, long id) {                   switch (position) {                 case 0://do same remaining items                     intent myintent = new intent(getapplicationcontext(), abc.class);                     startactivity(myintent);                     break;                  default:                     break;                 }               }             //finish();         }     }); }        private void initcomponent()         {          gridview = (gridview) findviewbyid(r.id.month_gridview);          }

android - Ext.device.Connection.isOnline() and Ext.browser.is.WebView not working on Sencha Touch 2.0.1 -

i working on android app sencha touch, ext.device.connection.gettype() returning unknown me. have found work around navigator.online function (from determine if net connection available). little alarmed basic functionality not working documented (http://docs.sencha.com/touch/2-0/#!/api/ext.device.connection). looking source code (http://docs.sencha.com/touch/2-0/source/connection2.html#ext-device-connection) saw connection constructor checks ext.browser.is.webview , got curious. running next line logs lot of seemingly wrong information:

for (prop in ext.browser.is) { console.log('ext.browser.is.' + prop + ': ' + ext.browser.is[prop]); }

for example:

ext.browser.is.safari: true ext.browser.is.webview: false ext.browser.is.webview: false

are these ext.browser.is properties wrong? seems ext.browser.is properties cause lot of other issues in app , connection.isonline symptom of deeper issue. there specific technique or code getting ext.device.connection.isonline() work?

if got 'ext.device.device' & 'ext.device.connection' in apps' requirements , next permissions in androidmanifest.xml:

<uses-permission android:name="android.permission.internet" />    <uses-permission android:name="android.permission.access_network_state" /> <uses-permission android:name="android.permission.read_phone_state" />

Simulating 'access denied' for a file in C# / Windows -

i'm attempting write integration tests little c# routine, reads different files.

and, well, accidentally thought great have test, specifies behavior case when access file denied.

does know nice , simple way simulate in test sandbox?

i suspect emulated using directorysecurity, however, i'm not sure if it's possible correctly cases:

assume that, example, can strip access rules current user, running tests (and require uac / elevation).

i guess in case i'd lose ability restore these rights , dispose sandbox correctly after test finished (without diving stuff impersonation , access token manipulations).

i moles or other mock-based approach, i'm more interested in general solution (for example, reuse test native application).

what missing? simple way this?

you don't want acheive via security settings, instead, why not exclusive access file somewhere else?

using(file.open(path, filemode.open, fileaccess.readwrite, fileshare.none)) { //hold here maintain file locked }

c++ - Which threading model should be used to create a Feed Handler Or Adaptor -

hi experts out there :)

this first question here.

problem description :

i have write market info feed handler. going windows service, using 2 sockets.

socket : communication between subscribing applications , feed handler (feed handler accepting connection request , item request).

socket b : communication between feed handler , external market info provider, reuters/bloomberg.

in both cases request/response using same port.

note : volume of info coming external scheme low (external scheme send info has been subscribed for, @ point of time). later on may want scale it, providers throw data, , feed handler has filter out locally, based on subscription.

my questions :

what threading model should use? which i/o strategy should use? keeping in mind both cases, should create separate request/response thread?

edit 1: after reading few tutorials on winsock, i'm planning utilize event objects asynchronous behavior.

the point of concern here that, single thread should hear incoming client connections (accept them) , connect other server, in turn send/recv on 2 different ports.

thread 1) listening incoming connections. (continuous) 2) receiving subscribe/unsubscribe request connected clients. (rarely) 3) connect external server (onetime only). 4) forwards request coming client external server. (rarely) 5) receive info external server. (continuous) 6) send info connected clients. (continuous)

my question can single thread deed both client , server, using asynchronous i/o models?

thanks in advance. deepak

the easiest threading model seems single threaded synchronous. if need implement filter provider, implement socket-in/socket-out separate process.

php - Doctrine generates 300+ queries, how can I avoid that? -

i'd understand little problem on symfony's project.

the database simple :

article

--id --name

tarif

--id --idarticle --seuil (threshold) --prix (price) --devise (currency)

i want select article have cost in euro query :

doctrine_query::create()->from('article') ->innerjoin('article.tarif tarif') ->where('tarif.devise = ?', '0') ->execute();

but in debug page have more 300 query, main query :

select a.id a__id, a.lot a__lot, a.ref a__ref, a.reflama a__reflama, a.refoem a__refoem, a.designation a__designation, a.idfamille a__idfamille, a.idcategorie a__idcategorie, a.couleur a__couleur, a.contenance a__contenance, a.poids a__poids, a.nbpages a__nbpages, a.etat a__etat, a.pack a__pack, a.pcb a__pcb, t.id t__id, t.idarticle t__idarticle, t.seuil t__seuil, t.prix t__prix, t.devise t__devise article inner  bring together tarif t on a.id = t.idarticle (t.devise = '0')

prolog - Incomplete to difference lists -

i want convert incomplete lists difference lists , vice versa.

this code convert regular list difference:

reg2diff(l,x-y):-append(l,y,x).

how go other direction?

incomplete difference list:

inc2diff(l,z):- ( nonvar(l) -> ( l=[_|t] -> inc2diff(t,z) ; l=[] -> z=[] ) ; l=z ).

use as

23 ?- l=[1,2,3|_],inc2diff(l,x). l = [1, 2, 3|x].  24 ?- l=[1,2,3|z],inc2diff(l,x). l = [1, 2, 3|x], z = x.  25 ?- l=[1,2,3],inc2diff(l,x). l = [1, 2, 3], x = [].

Pass php variables to external javascript -

this question has reply here:

how pass variables , info php javascript? 13 answers

how can pass php variables external javascript file? found lot of questions regarding can't figure out anyhow.

in html file have link

<script type="text/javascript" src="myscript.php"></script>

this myscript.php file have been trying output javascript file:

<? header("content-type: text/javascript"); ?>  $(document).ready(function() {  $("#validate_form").validate({     rules: {         page_title: "required",         seo_url: "required"     },      messages: {         page_title: "<?=$page_title?>",         seo_url: "<?=$seo_url?>"     }  });  });

append them using query string:

<script type="text/javascript" src="myscript.php?page_title=whatever&seo_url=whatever"></script>  <? header("content-type: text/javascript"); ?>  $(document).ready(function() {  $("#validate_form").validate({     rules: {         page_title: "required",         seo_url: "required"     },      messages: {         page_title: "<?=$_get['page_title'];?>",         seo_url: "<?=$_get['seo_url'];?>"     }  });  });

android - Action bar tabs - how to retrieve value from fragments in Activity? -

i've settings activity, has 3 tabs (each tab contains fragment) + in main activity there buttons row - buttons ok, , cancel.when press ok, this:

1) custom variables fragments 2) save them shared prefs

but how access fragment variables? tried this:

adding tabs in main activity:

    actionbar.tab tab1 = actionbar.newtab().settext(res.getstring(r.string.actsettingstab1));     tab1.settablistener(new mytabslistener(new tab1fragment(), "tab1"));     actionbar.addtab(tab1);     //...similar tabs

this tab listener:

class mytabslistener implements actionbar.tablistener {     private fragment fragment;     private string tag;      public mytabslistener(fragment fragment, string tag) {         this.fragment = fragment;         this.tag = tag;     }      @override     public void ontabreselected(tab tab, fragmenttransaction ft) {         //  nil     }      @override     public void ontabselected(tab tab, fragmenttransaction ft) {         ft.replace(r.id.fragment_container, fragment, tag);     }      @override     public void ontabunselected(tab tab, fragmenttransaction ft) {         ft.remove(fragment);     } }

and how variables fragments:

tab1fragment tab1 = (tab1fragment) fm.findfragmentbytag("tab1"); tab2fragment tab2 = (tab1fragment) fm.findfragmentbytag("tab2"); tab3fragment tab3 = (tab1fragment) fm.findfragmentbytag("tab3");

but it's unusual - findfragmentbytag returns fragment selected tab, otherwise returns null. when have selected tab1 , press ok, findfragmentbytag homecoming fragment tab1, null others.

maybe i'm doing wrong, or whole tring goind wrong way. how retrieve values fragments in parent activity , save them shared preferences?

separate process 2 steps:

1) gather settings fragments in real time (i.e. changed user). utilize listener pattern, fragments expose interface notify attached listener when user modifies of settings given fragment responsible for. allow activity attach listener fragments, , capture changes (store them in construction suits you).

2) allow activity save settings using sharedpreferences when ok button clicked. not have access fragments settings user has changed.

this way not have access fragments @ once, impossible if removed memory (as not visible anyway @ given time). instead, can re-assign activity listener selected fragment every time gets selected/displayed.

javascript - Why does storing a reference to a function then calling the function cause 'this' to have a context of window? -

i reading tutorial @ can understand _.bind , _bindall: http://blog.bigbinary.com/2011/08/18/understanding-bind-and-bindall-in-backbone.html

the website has next code

function developer(skill) {   this.skill = skill;   this.says = function(){     alert(this.skill + ' rocks!');   } } var john = new developer('ruby'); john.says(); //ruby rocks!

function developer(skill) {   this.skill = skill;   this.says = function(){     alert(this.skill + ' rocks!');   } } var john = new developer('ruby'); var func = john.says; func();// undefined rocks!

why storing reference function calling function cause have context of window?

when execute

a.b();

then a context of execution of b (this within b) unless b bound function.

if don't have a, if have

b();

then it's same as

window.b();

so window context of execution of b.

note that

a.b();

is same as

b.call(a);

and

b();

is same as

b.call(); // phone call replaces first argument global object if it's null or undefined

if want bind context, can (on modern browsers)

var func = john.says.bind(john); func();

or (more classically) utilize closure :

var func = function(){john.says()}; func();

How can I add \ symbol to the end of string in C# -

please forgive me beginner's question :)

string s="abc"; s+="\";

won't complile.

string s="abc"; s+="\\";

will create s="abc\\"

how can create s="abc\" ?

your sec piece of code is want (or verbatim string literal @"\" others have suggested), , adds single backslash - print console , you'll see that.

these 2 pieces of code:

s += "\\";

and

s += @"\";

are exactly equivalent. in both cases, single backslash appended1.

i suspect you're getting confused debugger view, escapes backslashes (and other characters). can validate debugger looking @ s.length, you'll see 4 rather 5.

1 note doesn't alter info in existing string, sets value of s refer new string consists of original backslash on end. string objects in .net immutable - that's whole other topic...

java - Using map to cache the data from the sql ( with <= timestamp col in it ) -

i set info next sql in map( because sql called many times , instead of going db everytime ), wondering how implement <= timestamp

edit:

i using oracle, updated tags, however, using preparedstatement in java caches queries, without beingness recompiled, our programme doesn't have cache solution cache info table. going db , getting info taking 2 ms roundtrip, getting info hashmap take nano second. query beingness executed around 20,000 times , load info , set within hashmap.

select ar table1 fk_col1 = ? , timestamp_col <= ? order date desc

the way did follows: not sure, timestamp_col in equals , hashcode right. suggest modifications?

public class table1key {     private string fk_col1;     private java.sql.timestamp timestamp_col;     //setters , getters here.     //implementing hashcode , equals.     @override     public int hashcode() {         final int prime = 31;         int result = 1;         result = prime * result                 + ((fk_col1 == null) ? 0 : fk_col1.hashcode());         result = prime * result                 + ((timestamp_col == null) ? 0 : timestamp_col.hashcode());          homecoming result;     }     @override     public boolean equals(object obj) {         if (this == obj)              homecoming true;         if (obj == null)              homecoming false;         if (getclass() != obj.getclass())              homecoming false;         table1key other = (table1key) obj;         if (fk_col1 == null) {             if (other.fk_col1 != null)                  homecoming false;         } else if (!fk_col1.equals(other.fk_col1))              homecoming false;         if (timestamp_col == null) {             if (other.timestamp_col != null)                  homecoming false;         } else if (!timestamp_col.equals(other.timestamp_col))              homecoming false;          homecoming true;     } }

...

private map<table1key, string> map = functions.gethashmapinstance();  public class functions { ...   public static <k,v> hashmap<k,v> gethashmapinstance() {        homecoming new hashmap<k,v>();   } }

so, populate map following:

private void populatemap() throws sqlexception {        seek {         ps = conn.preparestatement(table1sql);         ps.setfetchsize(20000);         resultset rs = ps.executequery();         while(rs.next()) {             table1key rdk = new table1key();             string ar = rs.getstring(1);             rdk.setfk_col1(rs.getstring(2));             rdk.settimestampcol(rs.gettimestamp(3));             if(actualratemap.get(rdk) == null) {                 actualratemap.put(rdk, ar);             }         }     }  grab (sqlexception e) {         e.printstacktrace();         throw e;     } {         ps.close();     }   }

//set key here.

table1key tk = new table1key(); tk.setfk_col1(col1); tk.settimestampcol(timestamp); string ar = actualratemap.get(tk);

//my main concern here .. work if sql has timestamp_col = ?, if timestamp_col < nowadays in map?

if(actualrate != null) { logger.info("actual rate:"+actualrate); }

hashmap doesn't job case, rather treemap can help.

a): rangemap solution

guava rangemap designed handle such case:

//initial rangemap   final rangemap<java.sql.timestamp, string> cache = treerangemap.create(); ... string value = cache.get(thistimestamp); if(value == null){      string queryfromdb = ...;//query db      cache.put(range.atmost(thistimestamp), queryfromdb);      value = queryfromdb; }

of course, 'fk_coll' problem. define map<string/*fk_coll*/, rangemap<java.sql.timestamp, string>> handle case.

b): treemap solution

final treemap<java.sql.timestamp, string> cache = new treemap<>(); ... //get  to the lowest degree key greater or equal 'thistimestamp'  map.entry<java.sql.timestamp, string> entry = cache.ceilingentry(thistimestamp); if(entry == null){    string queryfromdb = ...;//query db    cache.put(thistimestamp, queryfromdb);    value = queryfromdb; } else {    value = entry.getvalue(); }

and

hashmap<string/*fk_coll*/, treemap<java.sql.timestamp, string>>

handles 'fk_coll'.

plus: evict problem in cache case.

Android showing database in SwipeView -

i have swipeview 2 different views(fragments) via viewpager. want these 2 pages show different info sqllite database. problem cant figure out how this, main activity not able access views (tablelayout) on fragments , fragments sourcecode cant access database because adapter wont open (context of adapter super.getactivity()). there way this?

code of fragment:

dbadapter adapter = new dbadapter(getactivity());  @override public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {     // todo auto-generated method stub      if(container==null){          homecoming null;     }       layout=(relativelayout)inflater.inflate(r.layout.layout_morning, container, false);        adapter.open();     adapter.close();

code of dbadapter:

    private static string db_name = "database.dat";  private final context context; private databasehelper dbhelper; private sqlitedatabase db;  public dbadapter(context ctx) {     this.context = ctx;     dbhelper = new databasehelper(context); }  private static class databasehelper extends sqliteopenhelper {      databasehelper(context context) {         super(context, db_name, null, 1);     }      @override     public void oncreate(sqlitedatabase db) {      }      @override     public void onupgrade(sqlitedatabase db, int oldversion, int newversion) {      } }  public dbadapter open() throws sqlexception {      db = dbhelper.getwritabledatabase();      homecoming this; }  public void close() {     if (db!=null){         db.close();     }     dbhelper.close(); }

error nullpointerexception

of course of study can access database within fragment, need utilize getactivity(); instead of this.

example save image file within fragment class:

db = new databasehandler(getactivity()); bytearrayoutputstream stream = new bytearrayoutputstream(); photo.compress(bitmap.compressformat.jpeg, 100, stream); byte[] imageinbyte = stream.tobytearray(); db.updateuser(imageinbyte); db.close();

.htaccess - htaccess seo friendly urls for all subfolders -

i have script in index.php in folders

need create pretty url/seo friendly urls this: site.com/folder1/something.html

now have ugly urls this: site.com/folder1/index.php?category=something

this part index.php?category=something same in subfolders, want alter more seo friendly something.html

once again: find index.php?category=1$ , replace 1$.html not touch else, part of url

so when visit:

site.com/another-subfolder/and-one-more-folder-here/index.php?category=something

need see in address bar:

site.com/another-subfolder/and-one-more-folder-here/something.html

i hope it?

i tried folder1 in htaccess in root

rewriterule ^folder1/(.*).html$ folder1/index.php?category=$1 [l,r=301]

ok works, how can create work subfolders accross site this:

site.com/folder145/index.php?category=something site.com/subfolder/index.php?category=something site.com/another-subfolder/and-one-more-folder-here/index.php?category=something

there 1000s of subfolders different names manually making rewriterule each subfolder won't work

any help appreciated

first, need alter links generate index.php?category= form category.html form.

then in htaccess file in document root, add together these rules internally rewrite category.html form index.php?category= form:

rewriteengine on  rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule ^(.+?/)?([^/]+)\.html$ /$1index.php?category=$2 [l]

then, point links don't have command on (or ones generated using form) externally redirect direct access links in index.php?category= form:

rewritecond %{the_request} ^(get|head)\ (/.*?)?/index\.php\?category=([^&\ ]+) rewriterule ^(.+?/)?index\.php$ /$1%3.html? [l,r=301]

this should match , every subdirectory.

Create a two dimensional javascript array from PHP array -

how create php array:

 array(12) {     [0]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "8" ["name"]=> string(10) "accounting" ["main_category_id"]=> string(1) "1" } }      [1]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "1" ["name"]=> string(17) "applications" ["main_category_id"]=> string(1) "2" } }      [2]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "2" ["name"]=> string(19) "benefit claims" ["main_category_id"]=> string(1) "2" } }      [3]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "3" ["name"]=> string(22) "evaluations" ["main_category_id"]=> string(1) "2" } }      [4]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "4" ["name"]=> string(11) "leave forms" ["main_category_id"]=> string(1) "2" } }      [5]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "5" ["name"]=> string(13) "payroll" ["main_category_id"]=> string(1) "2" } }      [6]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "6" ["name"]=> string(17) "recruitment" ["main_category_id"]=> string(1) "2" } }      [7]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "7" ["name"]=> string(24) "training" ["main_category_id"]=> string(1) "2" } }      [8]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(1) "9" ["name"]=> string(13) "staff" ["main_category_id"]=> string(1) "2" } }      [9]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(2) "10" ["name"]=> string(14) "codes" ["main_category_id"]=> string(2) "3" } }      [10]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(2) "11" ["name"]=> string(28) "reports" ["main_category_id"]=> string(2) "3" }     [11]=> array(1) { ["subcategory"]=> array(3) { ["id"]=> string(2) "12" ["name"]=> string(14) "plan" ["main_category_id"]=> string(2) "4" } }      }

look in javascript:

var subcat[ ["accounting"], ["applications","benefit claims","evaluations","leave forms","payroll","recruitment","training","staff"], ["codes","reports"], ["plan"] ];

i tried couple of different php:

<?php     $jsarray = array();     foreach($data $row) {         $jsarray[] = array($row['subcategory']['name']);     }     echo json_encode($jsarray);     ?>

also tried this:

<?php       echo "[";      foreach($data $row){         foreach($row $subcat) {             echo "\"" . $subcat['name'] . "\",";            }      }echo "]"; ?>

what doing wrong?

like said above, pretty close json_encode example. need introduce sec dimension under main_category_id.

<?php $data = array(     array("subcategory"=> array("id"=>"8", "name"=>"accounting","main_category_id"=>"1")),     array("subcategory"=> array("id"=>"1", "name"=>"applications","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"2", "name"=>"benefit claims","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"3", "name"=>"evaluations","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"4", "name"=>"leave forms","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"5", "name"=>"payroll","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"6", "name"=>"recruitment","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"7", "name"=>"training","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"9", "name"=>"staff","main_category_id"=>"2")),     array("subcategory"=> array("id"=>"10", "name"=>"codes","main_category_id"=>"3")),     array("subcategory"=> array("id"=>"11", "name"=>"reports","main_category_id"=>"3")),     array("subcategory"=> array("id"=>"12", "name"=>"plan","main_category_id"=>"4")), ); $selected = 7;  $js = array();  foreach($data $sub){     //get parent id (main_category_id)     $parent = $sub['subcategory']['main_category_id'];     //if parent doesn't exist,  add together     if(!isset($js[$parent])){         //add array name , id         $js[$parent] = array(array('id'=>$sub['subcategory']['id'],'name'=>$sub['subcategory']['name']));     //parent exist     } else {         //append entry name , id         $js[$parent][] = array('id'=>$sub['subcategory']['id'],'name'=>$sub['subcategory']['name']);     } }  echo json_encode($js);

php - How does one interpret Xdebug computerized trace output? -

xdebug outputs computerized output in next form:

5   33  0   0.003569    193040  function_exists 0       e:\dropbox\websites\flyingpiranhas\wireframework\vendor\swiftmailer\swiftmailer\lib\swift_required.php  24  1   '_swiftmailer_init' 5   33  1   0.003609    193040 5   34  0   0.003620    193008  swift::registerautoload 1       e:\dropbox\websites\flyingpiranhas\wireframework\vendor\swiftmailer\swiftmailer\lib\swift_required.php  32  1   $callable = '_swiftmailer_init' 6   35  0   0.003661    193472  spl_autoload_register   0       e:\dropbox\websites\flyingpiranhas\wireframework\vendor\swiftmailer\swiftmailer\lib\classes\swift.php   79  1   array (0 => 'swift', 1 => 'autoload') 6   35  1   0.003712    193560 5   34  1   0.003728    193240

as can see, function id 33 entered stack, exited, normal. @ 34. function phone call 34 enters stack, 35 runs , executes, , 34's exit printed.

what i'm wondering is, how interpret this? mean function 34 lasted 108 miliseconds (until lastly line) , waited 35 finish, or should @ 41ms duration, is, until function 35 started? related "level"? if so, how?

you're correct, 34 waited 35 finish lasting 108 milliseconds.

How to check if edge exists between two vertices of graph, in Python? -

i have simple graph , want create method "get_edge" take 2 vertices arguments , homecoming border between them if exists, , none otherwise. here's snippet of i've tried. doesn't work because creates object instead of checking if there 1 in existence already. what's simplest way write get_edge()?

def add_edge(self, e):     """adds ,  border graph adding entry in both directions.      if there  border connecting these vertices,     new  border replaces it.     """     v, w = e     self[v][w] = e     self[w][v] = e  def get_edge(self, v1, v2):     try:         edge(v1, v2)         print 'edge exists'     except:         print 'edge not exist'          homecoming none

i suspect want like:

def get_edge(self, v1, v2):     try:         e = self[v1][v2] # order shouldn't matter         print("edge exists")          homecoming e     except keyerror:         print("edge not exist")          homecoming none

i'm assuming class derived dict or has __getitem__ method works , raise keyerror if inquire key doesn't exist. if don't need print statements (that is, they're debugging), can away e variable , homecoming result directly.

...

the site built using asp.net 4 , mvc 4. works fine on development machine running windows 8. i've copied system.web.razor.dll bin folder on server doesn't create difference, though appears v1.0 versioned assembly (~260k).

i've looked in c:\windows\assembly , don't see in there system.web.razor. however, have next 2 files:

c:\windows\assembly\nativeimages_v4.0.30319_64\system.web.razor\04eb82505c0086e8eb097d1408183aa0\system.web.razor.ni.dll (776k, file version: 1.0.20105.407)

however, copying v2 assembly here didn't work, though don't think right file anyway v1 assembly file sizes don't match either.

any ideas on going on here?

i'm guessing hosting provider doesn't have installed (as maintain telling me set in bin folder), i'm curious why can't find system.web.razor v2 dll anywhere.

to debug, uploaded empty website basic template worked fine. interestingly, when added reference postal , deployed again, got error - when reverted files back, error persisted! why happen?

any help appreciated. starting sense little out of ideas.

edit 1

created new empty project, added razor 2 nuget, set system.web.razor.dll re-create local (2.0.20715.0, 260k), published, grabbed file , uploaded it, , still same error? seems dll won't picked up.

edit 2

eventually gave trying utilize hosting provider in question. didn't have asp.net mvc 4 installed on server, think problem. tried different host have installed , works fine.

when test file problem:

cannot instantiate class: org.apache.naming.java.javaurlcontextfactory

can tell me how can solve problem? , find problem java code?

i fixed adding libraries apache tomcat run-time test libraries.

in netbeans:

project properties -> libraries -> run tests add together jar/folder

the 2 libraries needed catalina.jar , tomcat-juli.jar. mileage may vary.

i found them under installation directory tomcat. e.g:

apache-tomcat-7.0.34/bin/tomcat-juli.jar apache-tomcat-7.0.34/lib/catalina.jar

note 1 of jars in bin directory, other in lib directory

this isn't best way prepare problem. improve have different way inject datasource.

public class propertypageitem     {         private string _item1;         private string _item2;          public propertypageitem()         {             _item1 = "item1";             _item2 = "item2";         }          [description("item1")]         [category("item-field")]         public string item1         {                         {                  homecoming _item1;             }             set             {                 _item1 = value;             }         }          [description("item2")]         [category("item-field")]         public string item2         {                         {                  homecoming _item2;             }             set             {                 _item2 = value;             }         }     }

the class above not dynamic (doesn't consider events etc), it's sake of understanding method.

how can link/expose class visual studio property window? it's same window can see file properties while browsing through solution explorer. objective utilize window , not create property grid control.

tried next instructions on link confused me further.

after little research figured out how it.

follow instructions in link

in step 6 of walkthrough, replace 'this' 'new propertypageitem()'

public override void ontoolwindowcreated() {     arraylist listobjects = new arraylist();     listobjects.add(new propertypageitem());     selectlist(listobjects); }

following until step 7 on "exposing properties properties window" section, objective achieved , properties in propertypageitem class exposed onto visual studio propertywindow.

hope helpful.

iphone - UIScrollView PhotoViewer receives memory warning after 125 photos on iPod -

i stuck in weird problem,tried find out solution possible sources no luck yet.

my requirement similar photoviewer app of iphone,but there more uploading image,downloading etc .so technically doing creating main scrollview,which has content size equal selected image size * image width .i have little view within equal no. of images selected picker .the view contains little scrollview,and image view allows user zoom,pinch etc , main scroll view has gesture listner allows swipe. access images storing asset url , image when user swipes left or right .at point in time keeping 1 image memory i.e if user swipe 2nd photo delete 1st photo main scrollview .

but still facing memory issues on ipod if selected 125 photos , swipe multiple times end , come .

sample code.:-

    ***//innerscrollview class contains view scroll , imageview     //the values of initial , final counter diffrence of 1 creates 1 object**       for(int j=initialcounter;j<finalcounter;j++) {               innerscrollview *innerscrollviewobj=[[innerscrollview alloc] initwithframe:cgrectmake(320*j, 0, 320, 480)                                                                                    url:[selectedimagelist objectatindex:j] tag:self.initialimageviewcounter];             innerscrollviewobj.delegate=self;             [mainscrollview addsubview:innerscrollviewobj];             [innerscrollviewobj release];             innerscrollviewobj=nil;         }  **//this main scrollview gets created once**           mainscrollview = [[uiscrollview alloc] initwithframe:cgrectmake(0,0 , 320, 480)];         mainscrollview.pagingenabled = yes; //        mainscrollview.delegate=self;         mainscrollview.showshorizontalscrollindicator = no;         mainscrollview.showsverticalscrollindicator = no;         mainscrollview.maximumzoomscale = 4.0;         mainscrollview.minimumzoomscale = 1.0;         mainscrollview.backgroundcolor=[uicolor blackcolor];         [mainscrollview setcancancelcontenttouches:no];         mainscrollview.clipstobounds = yes;         mainscrollview.scrollenabled = false;         mainscrollview.contentsize = cgsizemake(320*[selectedimagelist count], mainscrollview.bounds.size.height);         [self.view addsubview:mainscrollview];  //this method gets called when swipe left , previous images gets deleted  -(void)deletescrollviewformmainview:(nsnumber*)indextodelete{      @try{         nslog(@"scrollview deleted %@",[[mainscrollview subviews] objectatindex:0]);         [[[mainscrollview subviews] objectatindex:0] removefromsuperview];      }     @catch (nsexception *e) {         nslog(@"scrollview view exception %@",[e description]);     } }       - (id)initwithframe:(cgrect)frame url :(alasset*) imageurl tag:(int)tag {     self = [super initwithframe:frame];     if (self) {          self.userinteractionenabled=yes; //        self.tag=tag;         uiimage *image = [uiimage imagewithcgimage:[[imageurl defaultrepresentation] fullresolutionimage ]];         uiimageview* imageview = [[uiimageview alloc] initwithimage:image];         imageview.tag = view_for_zoom_tag;         imageview.frame=cgrectmake(0, 0, self.frame.size.width, self.frame.size.height);         imageview.backgroundcolor=[uicolor clearcolor];         imageview.contentmode=uiviewcontentmodescaleaspectfit;         uiscrollview* pagescrollview = [[uiscrollview alloc] initwithframe:cgrectmake(0, 0, self.frame.size.width, self.frame.size.height)];         nslog(@"page scrollview %@",pagescrollview);         pagescrollview.tag=tag;         pagescrollview.minimumzoomscale = 0.4f;         pagescrollview.maximumzoomscale = 2.0f;         pagescrollview.zoomscale = 1.0f;         pagescrollview.backgroundcolor=[uicolor clearcolor];         pagescrollview.delegate = self;         pagescrollview.showshorizontalscrollindicator = no;         pagescrollview.showsverticalscrollindicator = no;         [pagescrollview setcancancelcontenttouches:no];         [self addsubview:pagescrollview];         [pagescrollview addsubview:imageview];            uitapgesturerecognizer *singletap = [[uitapgesturerecognizer alloc] initwithtarget:self action:@selector(handlesingletap)];         singletap.numberoftapsrequired=1;         singletap.delegate=self;         [self addgesturerecognizer:singletap];         singletap=nil;          uitapgesturerecognizer *doubletap = [[uitapgesturerecognizer alloc] initwithtarget:self action:@selector(handledoubletap)];         doubletap.numberoftapsrequired=2;         doubletap.delegate=self;         [self addgesturerecognizer:doubletap];          singletap=nil;         doubletap=nil;         imageview=nil;         pagescrollview=nil;      }      homecoming self; }

should create innerimageview class singelton class?will help,because think memory issues can because multiple objects getting created(though release properly).

please help guys.!! in advance.

can post definition of innerscrollview? problem delegate property retain, keeping innerscrollviewobj beingness deallocated.

so, assume have like:

@property (nonatomic, retain) id delegate;

which should be:

@property (nonatomic) id delegate;

or, if enable arc should be:

@property (nonatomic, weak) id delegate;

also, maintain in mind [mainscrollview subviews] holds views, not controllers. if deallocate controller not able respond events or command anything, , may errors due sending messages deallocated objects.
