truecrypt - True crypt auto mounting on start-up does not work -

since yesterday true-crypt partition not automount on startup os every time (sometimes works, doesn't).

yes set scheme favorites , checkbox mount on startup set. yes have same password, typed same (en intl) layout. yes worked somehow before few times.

thanks help.

edit: os: windows 8

update seems not work cold starts.

warm starts seem work

i have problem on windows 8 laptop. tracked problem new shutdown process windows 8. won't total shutdown/startup when do, sort of hybrid shutdown (http://superuser.com/questions/496241/are-there-downsides-to-windows-8-hybrid-shutdown)

i found if utilize normal charm -> settings -> powerfulness -> shutdown, fail load encrypted partition when got desktop.

however, if utilize command line "shutdown.exe /s /t 0" shutdown, reliably load next time start up.

i forced prepare way because dropbox on encrypted partition, , dropbox complain couldn't find folder anymore (same google drive , skydrive, worse).

this might prepare problem, haven't tried yet (http://www.askvg.com/fix-windows-8-restart-and-shutdown-problems-by-disabling-hybrid-shutdown-feature/)

machine learning - Feature extraction from a single word -

usually 1 wants feature text using handbag of words approach, counting words , calculate different measures, illustration tf-idf values, this: how include words numerical feature in classification

but problem different, want extract feature vector single word. want know illustration potatoes , french fries close each other in vector space, since both made of potatoes. want know milk , cream close, hot , warm, stone , hard , on.

what problem called? can larn similarities , features of words looking @ big number documents?

i not create implementation in english, can't utilize databases.

hmm,feature extraction (e.g. tf-idf) on text info based on statistics. on other hand, looking sense (semantics). hence no such method tf-idef work you.

in nlp exists 3 basic levels:

morphological analyses syntactic analyses semantic analyses

(higher number represents bigger problems :)). morphology known bulk languages. syntactic analyses bigger problem (it deals things verb, noun in sentence,...). semantic analyses has challenges, since deals meaning quite hard represent in machines, have many exceptions , language-specific.

as far understand want know relationships between words, can done via so-called dependency tree banks, (or treebank): http://en.wikipedia.org/wiki/treebank . database/graph of sentences word can considered node , relationship arc. there treebank czech language , english language there some, many 'less-covered' languages can problem find 1 ...

asp.net - How to Check Only one RadioButton of a Row with Different Fileds binded in Row? -

i have grid 5 columns, in 3 radiobuttons of different fileds. want have status of checking 1 radiobutton of row,

my code is

<asp:templatefield itemstyle-horizontalalign="center" headertext="directpol">     <itemtemplate>         <asp:radiobutton id="rddirectpol" runat="server" checked='<%#convert.toboolean(eval("pol"))%>'/>     </itemtemplate> </asp:templatefield> <asp:templatefield itemstyle-horizontalalign="center" headertext="directpod">     <itemtemplate>         <asp:radiobutton id="rddirectpod" runat="server" checked='<%# convert.toboolean(eval("pod")) %>' />     </itemtemplate> </asp:templatefield> <asp:templatefield itemstyle-horizontalalign="center" headertext="indirectpol">     <itemtemplate>         <asp:radiobutton id="rdindirectpol" runat="server" checked='<%#convert.toboolean(eval("ispol"))%>' />     </itemtemplate> </asp:templatefield>

in doing can see 3 can checked @ 1 time, want restrict 1 @ time..., can 1 please help me

set groupname property:

<asp:templatefield itemstyle-horizontalalign="center" headertext="directpol">     <itemtemplate>         <asp:radiobutton id="rddirectpol" runat="server" checked='<%#convert.toboolean(eval("pol"))%>'          groupname="group1" />     </itemtemplate> </asp:templatefield> <asp:templatefield itemstyle-horizontalalign="center" headertext="directpod">     <itemtemplate>         <asp:radiobutton id="rddirectpod" runat="server" checked='<%# convert.toboolean(eval("pod")) %>'          groupname="group1" />     </itemtemplate> </asp:templatefield> <asp:templatefield itemstyle-horizontalalign="center" headertext="indirectpol">     <itemtemplate>         <asp:radiobutton id="rdindirectpol" runat="server" checked='<%#convert.toboolean(eval("ispol"))%>'          groupname="group1" />     </itemtemplate> </asp:templatefield>

this way, 1 radiobutton checked each radiobutton same groupname. in case, you'll have set 1 groupname per row.

html prevent scrolling also prevents html5 input type range -

i have html web app, , adding sliders so:

<form oninput="output1.value=slider1.value">   <input type="range" name="slider1" value="50"/>   <output name="output1" for="slider1">50</output> </form>

works great on web, , on device.

now, when add together in preventdefault code stop page scrolling breaks:

document.addeventlistener( 'touchmove' , function(e) {e.preventdefault()} , false );

now, if own control, prepare it, want default behavior of html5 slider, how can back?

not sure duplicate, in case:

function stopscrolling( touchevent ) {     if ((touchevent.target.id != "pastgenslider") && (touchevent.target.id != "curgenslider"))         touchevent.preventdefault();  } document.addeventlistener( 'touchmove' , stopscrolling , false );

just check id element has, , if want allow process, allow pass/do not phone call preventdefault();

objective c - Setting composite drawing mode causing black holes/patches on NSWindow -

i wanted draw shape, on wanted draw smaller transparent shape.

i've tried nsimage forst , on view, still getting same result.

the oval appears black because windows opaque default. you've cutting oval track in window, because window opaque, without industrial laser cutting same oval in monitor, mac has show some color there instead. color shows color of clearcolor: black.

the solution set window's opaque no.

the default yes, nice , efficient (well, actually, because) prevents other windows' contents showing through. setting no allow see behind window through lean oval track. (it'll work improve if fill oval, giving larger window in the… er… window.)

(why track filled gray? that's window's shadow you're seeing there. when seek real, you'll able see other windows on scheme through track move window around.)

php - Calculate 2 timestamp in attendance -

any ideas how calculate attendance datetime in mysql.

for example: want total hours person worked in day. in given.

mysql structures:

----------------------------------------------------- id   |   datetime         |   status    |  employeeid ----------------------------------------------------- 1    | 18-feb-13 8:00:00  |  check in   |    100a 2    | 18-feb-13 10:00:00 |  check in   |    100a 3    | 18-feb-13 17:00:00 |  check out   |    100a

still total hours 8 hours excluding break time 12:00 pm.

here's php way date math:

$datetime1 = datetime::createfromformat('d-m-y g:i:s', '18-feb-13 8:00:00'); $datetime2 = datetime::createfromformat('d-m-y g:i:s', '18-feb-13 17:00:00'); $interval = $datetime1->diff($datetime2); $elapsed = $interval->format('%h hours %i minutes %s seconds'); echo $elapsed;

see in action

you'll need more math deal breaks should started.

php - Using a regular expression to validate an email address -

over years have developed regular expression validates email addresses correctly, assuming don't utilize ip address server part.

i utilize in several php programs, , works of time. however, time time contacted having problem site uses it, , end having create adjustment (most realized wasn't allowing 4-character tlds).

what's best regular look have or have seen validating emails?

i've seen several solutions utilize functions utilize several shorter expressions, i'd rather have 1 long complex look in simple function instead of several short look in more complex function.

there no simple regular look problem: see this rfc‑822–compliant regex, simple. (it written before days of grammatical patterns.) grammar specified in rfc 5322 complicated primitive regular expressions.

the more sophisticated grammatical patterns in perl, pcre, , php can manage correctly parse rfc 5322 without hitch. python , c# should able manage it, utilize different syntax first three. however, if forced utilize 1 of many less powerful pattern-matching languages, it’s best utilize real parser.

it's of import understand validating per rfc tells absolutely nil whether address exists @ supplied domain, or whether person entering address true owner. people sign others mailing lists way time. fixing requires fancier kind of validation involves sending address message includes confirmation token meant entered in same web page address.

confirmation tokens way know got address of person entering it. why mailing lists utilize mechanism confirm sign-ups. after all, can set downwards president@whitehouse.gov, , parse legal, isn't person @ other end.

for php, should not utilize pattern given in validate e-mail address php, right way quote:

there danger mutual usage , widespread sloppy coding found de facto standard e-mail addresses more restrictive recorded formal standard.

that no improve other non-rfc patterns. isn’t smart plenty handle rfc 822, allow lone rfc 5322. this one, however, is.

if want fancy , pedantic, implement finish state engine. regular look can deed rudimentary filter. problem regular expressions telling valid e-mail address invalid (a false positive) because regular look can't handle rude , impolite user's perspective. state engine purpose can both validate , right e-mail addresses otherwise considered invalid disassembles e-mail address according each rfc. allows potentially more pleasing experience, like

the specified e-mail address 'myemail@address,com' invalid. did mean 'myemail@address.com'?

see validating email addresses, including comments. or comparing e-mail address validating regular expressions.

asp.net - ClientID via FindControl() different from Generated ID in html -

i have literal defined in usercontrol embedded in aspx , embedded in masterpage.

this.parent.findcontrol("literror") returns me control... client id "phcontent_literror". find command on server side code...

when generated html, see "ctl00_ctl00_phcontent_literrorpanel"

is normal ?

my question because added initiator command ( button) dynamically in ajaxsettings of ajaxmanager update literror... however, when there error, update literror.text... wouldnt update on browser... led me check literror control...

the server side find command has ability find server controls name , have observed generated in page in order unique. normal. advertisement why field in ajax command not updating, need post more code.

node.js - npm local install package to custom location -

is possible specify custom bundle destination npm install, either through command flag or environment variable?

by default, npm local installs end in node_modules within current directory, want install node_modules within different directory, illustration vendor/node_modules. how can create happen?

tl;dr

you can using --prefix flag , --global* flag.

pje@friendbear:~/foo $ npm install bower -g --prefix ./vendor/node_modules bower@0.7.0 /users/pje/foo/vendor/node_modules/bower

*even though "global" installation, installed bins won't accessible through command line unless ~/foo/vendor/node_modules exists in path.

tl;r

every configurable attribute of npm can set in of 6 different places. in order of priority:

command-line flags: --prefix ./vendor/node_modules environment variables: npm_config_prefix=./vendor/node_modules user config file: $home/.npmrc or userconfig param global config file: $prefix/etc/npmrc or userconfig param built-in config file: path/to/npm/itself/npmrc default config: node_modules/npmconf/config-defs.js

by default, locally-installed packages go ./node_modules. global ones go prefix config variable (/usr/local default).

you can run npm config list see current config , npm config edit alter it.

in general, npm's documentation helpful. folders section structural overview of npm , config section answers question.

position - jquery inconsistent positioning using offset().top -

i trying position #elementa relative #elementb. half time ends 1 top value, half time gets another, , can't figure out why. #elementa begins css:

#elementa { display: block; opacity: 0; position: absolute; clear: both; margin-left: -49px; }

then, on $(document).ready(), set top value , fade in.

var p = $('#elementb').offset(); $('#elementa').css({ top: p.top - 2 }); $('#elementa').animate({opacity: 1}, 400);

why getting inconsistent results? there improve way this?

i found problem. thought because executing on $(document).ready() wouldn't have worry assets loading affecting positioning. turned out image above #elementa throwing off when didn't load in time. waiting $('other image').load() fixes it.

i implementing workflow of tasks in java program. 1 of tasks running commands on multiple linux servers.

the servers determined dynamically - read xml file. examined rundeck's api, seems have configure servers in advance, doesn't suit needs.

any ideas?

one reply utilize rundeck, think need rundeck dynamically load nodes.

to create dynamic need refresh project. restart rundeck or utilize api refresh method. haven't tried latter think improve solution. resource model supports files , getting node list of servers external source url.

but if rolling own improve reply maybe ssh , consider ssh library java

node.js - nodejs 'forever' just doesn't do anything -

i trying run nodejs app on amazon ec2 instance using forever. installed nodejs npm, , ran sudo npm install forever -g. installation didn't homecoming errors, go ahead , seek running app using forever start server.js, won't - no output what-so-ever, not error. tried forever --help , forever, none of them giving me response...

when running app regularly using nodejs - nodejs init.js works expected, need running using forever won't shut downwards when disconnect server.

edit : since problem having nodejs closing when closed terminal session ec2 server, solved using linux nohup command : nohup sudo nodejs server.js & kept nodejs running in kid process after closed terminal window.

thanks help though! :)

i not receiving stdout input forever command , prepare nailed it:

python - Detecting ImportError in imported module -

i want import python module if exists, ignore importerror if not. however, if imported module raises importerror, error ignored too, , that's not need (i.e. if module exists, has bug, want know).

for app in installed_apps:     try:         module = __import__('{}.mycustommodule'.format(app))         #     except importerror:         traceback = sys.exc_info()[2]         if ( ? ):  # if exception occurred in app.mycustommodel, raise             raise         pass       # otherwise, ignore

i checked docs sys.exc_info , traceback didn't find useful info. how can done?

if exception occurred in same function catching it, stack trace have 1 frame. otherwise, have multiple frames. after looking @ related questions , making tests, found out it's plenty check if tb_next none:

except importerror: traceback = sys.exc_info()[2] if ( traceback.tb_next ): raise pass

note: although documentation on tb_next scarce (saw reference in docs inspect, nil specifying constitutes traceback "level"), behavior above consistent between python 2.7.3, python 3.2.3, jython 2.5.3, ironpython 2.7.3 , pypy 1.8.0.

can point out doing wrong?

alright, figured out. error caused next code.

it seems cannot utilize binding under toolkit:gesturelistener. remove bindings , everything's working perfectly:)

Resizing a Image to selection rectangle Delphi -

hi cant figure out why wont work. have image , selection , want image same size , position selection set code in timer:

  procedure tfrmmainui.tmrupdatetimer(sender: tobject);   var : integer;    begin     image1.width:=selection1.width;     image1.height:=selection1.height;     image1.position.x:=selection1.position.x;     image1.position.y:=selection1.position.y;   end;

but doesn't work.

what supposed happen image resizes selection , position follows selection. happens can move , resize selection , image stays , doesn't resize.

as @mike sutton pointed out in comments, should using ontrack event of tselection trigger updates image.

the documentation says:

the event handler of ontrack event called cyclically mousemove method while tselection object in process of moving or resizing.

write custom ontrack event handler perform specific action when tselection in process of moving or resizing.

you state in comment, components created dynamically @ runtime, rather on designtime surface. need assign handler in code. this:

selection1.ontrack := selectiontrack;

your event handler this:

procedure tfrmmainui.selectiontrack(sender: tobject); begin   image1.width:=selection1.width;   image1.height:=selection1.height;   image1.position.x:=selection1.position.x;   image1.position.y:=selection1.position.y; end;

you in comments need track selection changes number of linked images , selections. can modify event handler this:

procedure tfrmmainui.selectiontrack(sender: tobject); var   selection: tselection;   image: timage; begin   selection := sender tselection;   image := imagefromselection(selection);//you need implement function   image.width:=selection.width;   image.height:=selection.height;   image.position.x:=selection.position.x;   image.position.y:=selection.position.y; end;

ios - How can I simulate app being killed in background? -

i'm trying verify app (app1) behaves correctly when shut downwards scheme after launches app (app2). there way simulate or forcefulness behavior?

telling simulator simulate memory warning while app2 running doesn't until app1 brought foreground. killing app1 debugger simulate same sequence of app events?

edit: app placed in background when launches sec app handle file. sec app relaunches app, , i'm trying verify app behaves correctly when scheme has shut downwards while sec app executing.

yes, if app in background already. app killed scheme while in background terminated no warning-- no app delegate methods called, no state changes made-- happens when debugger stop while app in background. (this presupposes you've set app in background clicking home button on simulator or cmd-shift-h)

(as @inafziger notes, can same effect using simulator's interface forcefulness quit running app.)

How can I add a note to a Visual Studio bookmark or line? -

when in middle of debugging find more 1 area can improved (or fixed) , mark them in such away can come later , create improvement.

currently add together bookmark line can't include notes can used remind me why bookmark there (you can alter name of bookmark isn't enough). suppose want able add together todo code while code running although edit , continue enabled not available in asp.net webforms (3.5) project.

are there visual studio features or extensions enable this?

instead of enabling edit , go on entering todo: source code, can create task list shortcut (key cord ctrl + k, ctrl + h).

this adds entry shortcuts section of task list window. there can alter description of task remind why created it.

php - How to set default value for form fields- Magento? -

i have admin form field(textbox),

$fieldset->addfield('ajax_time_interval', 'text', array(           'label'     => mage::helper('dealroom')->__('page refresh time interval'),           'class'     => 'required-entry',           'required'  => true,           'name'      => 'ajax_time_interval',       ));

i need set default value text field. tried, setting 'value' => '120', in it. not working.

$fieldset->addfield('ajax_time_interval', 'text', array(           'label'     => mage::helper('dealroom')->__('page refresh time interval'),           'class'     => 'required-entry',           'required'  => true,           'name'      => 'ajax_time_interval',           'value'     => '120',        ));

how set defalt value in field?

in case, setvalues() function overriding 'value' had set field.

cause:

in _prepareform() function, set value below:

$fieldset->addfield('ajax_time_interval', 'text', array(           'label'     => mage::helper('dealroom')->__('page refresh time interval'),           'class'     => 'required-entry',           'required'  => true,           'name'      => 'ajax_time_interval',           'value'     => '120',        ));

at end of _prepareform() function, there next line of code reset form values:

$form->setvalues($model->getdata());

solution:

set model info before setvalues() function below:

if (!$model->getid()) { $model->setdata('ajax_time_interval', '120'); } $form->setvalues($model->getdata());

java - Implementing idempotency for AWS Spot Instance Requests -

i'm using java aws sdk create ec2 spot instance requests. opposed on demand instances, api spot requests not have similar clienttoken , not back upwards idempotency out of box.

the straightforward way think of set launchgroup property unique uuid; when check phone call describespotinstancerequests , see if have request same launch group.

to surprise, seems there's delay before describe phone call returns spot requests sent before. wrote junit test , seems in order consistent have set timeout of @ to the lowest degree 60s between 2 calls (request spot instance , describe spot instance requests). need have granularity of 10s, because requests can repeated application @ interval, in case of failure - i.e. breaks after sent request before read result got amazon. in case don't want have request repeated, want see got registered , move on.

@test public void testrunspotinstances() throws exception {      activity.execute(execution);      timeout(timeout);      // shouldn't     activity.execute(execution);      timeout(timeout);      describespotinstancerequestsresult result = client.describespotinstancerequests(             new describespotinstancerequestsrequest().withfilters(new filter()                 .withname("launch-group").withvalues(business_key)));      assertthat(result.getspotinstancerequests()).hassize(1);      timeout(timeout); }

the test works every time if timeout set 60s; 40-50s works intermittently. below fails every time.

has managed work around delay? implementing idempotency spot requests possible using aws api , not having state saved in client application?

in case don't want have request repeated, want see got registered , move on.

if got 200 back, it's registered. may not show right away, it's registered , can move on in flow.

is implementing idempotency spot requests possible using aws api , not having state saved in client application?

i don't believe so. have same sort of issue amazon's emr. way work around have component who's job observe clusters. when create request emr cluster, cluster id, pass off observer. observer phone call other components when cluster changes state. not beingness acknowledged emr right away valid case , not treated exception.

i have no thought if that's appropriate you. perhaps seek maintaining spotinstancerequestid. in case, maintain them in memory, maintain them somewhere persistent if need be.

Simple Flip buffer (Vertically) issue in C\C++ -

i trying flip buffer, buffer doesn't processed. buffer of pixels , need flip vertically. can spot doing wrong? in advance.

void flipvertically(unsigned int* buffer, const unsigned int width, const unsigned int height) {     const unsigned int rowwidth = width; // length of row     const unsigned int rows = height / 2; // iterate half buffer  total flip     unsigned int* temprow = (unsigned int*)malloc(rowwidth);      (int rowindex = 0; rowindex < rows; rowindex++)     {         memcpy(temprow, buffer + (rowindex * rowwidth), rowwidth);         memcpy(buffer + (rowindex * rowwidth), buffer + (height - rowindex - 1) * rowwidth, rowwidth);         memcpy(buffer + (height - rowindex - 1) * rowwidth, temprow, rowwidth);     }      free(temprow); }

will work?

void flip(unsigned* buffer, unsigned width, unsigned height) {     unsigned rows = height / 2; // iterate half buffer  total flip     unsigned* temprow = (unsigned*)malloc(width * sizeof(unsigned));      (unsigned rowindex = 0; rowindex < rows; rowindex++)     {         memcpy(temprow, buffer + rowindex * width, width * sizeof(unsigned));         memcpy(buffer + rowindex * width, buffer + (height - rowindex - 1) * width, width * sizeof(unsigned));         memcpy(buffer + (height - rowindex - 1) * width, temprow, width * sizeof(unsigned));     }      free(temprow); }

<relativelayout>    <textview       android:layout_width="wrap_content"       android:layout_height="wrap_content"       android:text="@string/hello_world" />      <linearlayout       android:layout_width="fill_parent"       android:layout_height="200dip"       android:layout_alignparentbottom="true" >     </linearlayout> </relativelayout>

i want create linear layout transparent, meaning, content previous activity on activity stack should visible in linear layout region.

i have tried using setalpha(0) linear layout; create transparent, shows activity background color in linear layout region.

i have tried setting android:theme activity @android:style/theme.translucent.notitlebar, create whole activity show content of previous activity.

can suggest way?

thanks.

just clear, activities not visible objects. views see on screen -- in particular see view attached activity. in case view relativelayout , contents.

when create linearlayout transparent, shows background color of relativelayout. if want see behind relative layout create background color transparent, too.

<relativelayout android:backgrond="#00000000">         ...        <linearlayout android::background="#00000000">             ...        </linearlayout>  </relativelayout>

of course of study want utilize named color resource rather "#00000000"

php - How to appropriately respond when a query fails in a webapp? -

half of mysqli functions homecoming false on failure. problem shooting when developing great, when released how , should used? illustration if user encounters error technical info may not relevant should removed final product? part of me afraid if script problem happened included script, confuse people , mess scalability.

if(!$link)     die('can\'t connect mysql: '.mysql_error()); $db_selected = mysqli_select_db($link, 'storage1'); if(!$db_selected)     die('can\'t  utilize storage1: '.mysql_error());

you should never show these messages visitor / user.

instead should log error on server , display friendly message user seek 1 time again / seek 1 time again later / apologize / etc.

vim: using a regular key as a modifier -

i utilize <space> modifier, ctrl, alt or shift.

for example, hjkl keys jump 10 times instead of 1 when space pressed. like:

nnoremap <space-h> 10h nnoremap <space-j> 10j nnoremap <space-k> 10k nnoremap <space-l> 10l

this works:

nnoremap <space>j 10j

but need release <space> , press 1 time again repeat custom movement.

arpeggio vim plugin lets define keymappings of simultaneous keys other keys, e.g. j , k @ same time have same effect <esc>.

by replacing every occurrence of <? <?php script parses fine, seems case have short_open_tag set off. can either turn on in php.ini file (you can't utilize ini_set), or switch using total open tag (which i'd recommend allows you, example, utilize <?xml version="1.0" ?> in html files without having echo it.).

slidingmenu - Use a container for Android activities -

i want know if android back upwards possibility create container static components , include activities in it. have sliding menu onclicklistener events , don't want set these events each activity.

if understood correctly, have functionality mutual several activities, , don't want repeat same code in of them. instead, want in 1 place.

one way accomplish create superclass activity, place mutual code in activity, , extend other activities. example,

public class baseactivity extends activity implements onclicklistener { private button button;  @override public void oncreate(bundle savedinstancestate) {   super.oncreate(savedinstancestate);   setcontentview(r.layout.main);   button = (button) findviewbyid(r.id.my_button);   button.setonclicklistener(this); }    ...  @override public void onclick(view view) {    int id = view.getid();    switch(id) {      case r.id.my_button:      // perform action      break;    } }

}

then extend as

public class activity1 extends baseactivity {   /... }  public class activity2 extends baseactivity {   /... }  public class activity3 extends baseactivity {   /... }

if delete these 2 macro, compiles , runs correctly.

after googling, know these 2 macros defined in sys/cdefs.h , kind of comment message.

but why won't compile in gcc?

well after going throuhg sys/cdefs.h (ubuntu 11.10), found no __copyright or __rcsid defination. guess these 2 macros defined in netbsd sys/cdefs.h. added them in new header file (i name "aeodefs.h") following:

#ifndef _aeodefs_h_ #define _aeodefs_h_ #include <sys/cdefs.h>  #define __idstring(name,string) \         static const char name[] __attribute__((__unused__)) = string  #ifndef __rcsid #define __rcsid(s) __idstring(rcsid,s) #endif  #ifndef __copyright #define __copyright(s) __idstring(copyright,s) #endif  #endif /* !_aeodefs_h_ */

then alter #include <sys/cdefs.h> #include "aeodefs.h".

it's done!

according docs,

the file returned file::temp have been opened in binary mode if such mode available. if not correct, utilize c function alter mode of filehandle.

as such, re-add :crlf nowadays on file handles opened in windows using next after open before print.

addresses can empty(so different null can't first item)

replace if(addresses != null) if(addresses != null && !addresses.isempty())

PHP object serialization and unserialization not working properly -

i have 3 source files follows:

first 1 source_class.php

class macmini {     public $memory = "16 gigabytes";     public $cpu = "intel core i7 @ 2.6ghz";     public $hd = "1tb @ 5200 rpms";     public function mem()     {          homecoming $this->memory;     }     public function centralpu()     {          homecoming $this->cpu;     }     public function hard_drive()     {          homecoming $this->hd;     } }

///////////////////////////////////////////////////

second 1 serialize.php

include "source_class.php"; $mymini = new macmini; $mymini->cpu = "intel core i7 @ 3.4ghz"; $serialized = serialize($mymini); file_put_contents("store", $serialized);

//////////////////////////////////////////////

third 1 unserialize.php

include "source_class.php"; $data = file_get_contents("store"); $unserialized = unserialize($data);  $mymini = new macmini; echo $mymini->cpu;

it produces next output: "intel core i7 @ 2.6ghz"

why, if property of cpu changed in serialize.php file, not reflected in unserialization? checked raw info contents of serialized file, "store" , cpu property reflected in serialized file when it's unserialized in unserialize.php property alter not reflected. why that? can explain?

the problem create new $mymini object , output cpu properity of newly created object. serialization/ unserialization doesn't create sense way.

change unserialize.php :

include "source_class.php"; $data = file_get_contents("store"); $mymini = unserialize($data); echo $mymini->cpu;

 <form method="post" action="insert.php">   <br>  <tr><td align="left"><strong>nurse information</strong></td>  </td>  <tr>   <td>nurse_name</td>        <td><select name="valuelist">     <option value="valuelist" name="nurse_name" value='<?php echo $nurse_name; ?>'></option>   </select></td>  <tr>

the query should populate nurse_forename:

<html><head><title>connect database</title></head><body> <font size="4">query gets forename of nurse</font> <br><br><font size="4">choose name</font><br><br>   <form action="insert.php" method="post"> <select name="valuelist">; <?php $value=$_post ["valuelist"]; $con = mysql_connect("localhost","root","") or die('could not connect: ' . mysql_error());  mysql_select_db("a&e", $con) or die('could not select database.');  $fetch_nurse_name = mysql_query("select distinct $nurse_name nurse"); $result = mysqli_query($con, $query) or die("invalid query");  while($throw_nurse_name = mysqli_fetch_array($fetch_nurse_name)) { echo '<option   value=\"'.$nurse_name['nurse_name'].'">'.$throw_nurse_name['nurse_name'].'</option>'; } echo "</select>";  mysqli_close($con);  ?> <input type="submit" value="submit"> </form></body></html>

try this:

<html><head><title>connect database</title></head><body>  <font size="4">query gets forename of nurse</font>  <br><br><font size="4">choose name</font><br><br>    <form action="insert.php" method="post"> <select name="valuelist">; <?php $value=$_post ["valuelist"]; $con = mysql_connect("localhost","root","") or die('could not connect:'.mysql_error()); mysql_select_db("a&e", $con) or die('could not select database.');  $fetch_nurse_name = mysql_query("select distinct forename nurse");   while($throw_nurse_name = mysql_fetch_array($fetch_nurse_name)) { echo '<option   value=\"'.$throw_nurse_name[0].'">'.$throw_nurse_name[0].'</option>'; } echo "</select>";   ?> <input type="submit" value="submit"> </form></body></html>

dont utilize mysql , mysqli together....you should utilize mysqli or pdo, not mix of both ;) ps: edited ;)

Http POST works on std Java does not work correctly on Android -

i banging head on next code works on std java command line not work in android on galaxy nexus running 4.2. i'm including 2 variations of attempting perform post http://cleverbot.com/webservicemin. original post logic taken chatterbot api revised logic effort utilize different http apis available in java. naive effort @ including chatterbot api in test project. original works main app on cmd line using standard java while neither version work in android.

private static string revisedpostlogic(string url, map<string, string> parameters) throws ioexception {     httpclient httpclient = new defaulthttpclient();     httppost httppost = new httppost(url);     list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>(parameters.size());     for(map.entry<string,string>eachentry : parameters.entryset())         namevaluepairs.add(new basicnamevaluepair(eachentry.getkey(),eachentry.getvalue()));     httppost.setentity(new urlencodedformentity(namevaluepairs));     httpresponse response = httpclient.execute(httppost);     bytearrayoutputstream rawresponse = new bytearrayoutputstream();     response.getentity().writeto(rawresponse);      homecoming rawresponse.tostring(); }  private static string old_post_logic(string url, map<string, string> parameters) throws exception {     urlconnection connection = new url(url).openconnection();     ((httpurlconnection) connection).setrequestmethod("post");     connection.setdooutput(true);     connection.setdoinput(true);     outputstreamwriter osw = new outputstreamwriter(connection.getoutputstream());     osw.write(parameterstowwwformurlencoded(parameters));     osw.flush();     osw.close();     reader r = new bufferedreader(new inputstreamreader(connection.getinputstream()));     stringwriter w = new stringwriter();     char[] buffer = new char[1024];     int n = 0;     while ((n = r.read(buffer)) != -1) {         w.write(buffer, 0, n);     }     r.close();      homecoming w.tostring(); }

with revised logic no response server exception , original logic eofexception.

update

i tried running android , desktop java , discrepancy:

new java.net.url("http://cleverbot.com/webservicemin").openconnection().getresponsecode()

on desktop java response code 200. (i haven't tried reading stream i'm guessing homecoming text "denied") on android "eofexception". on desktop java (using groovy shortcut now), dump response code, headers , response content , get:

response code: 200 headers: [null:[http/1.1 200 ok], sc:[6870], rps:[server52054], mime-version:[1.0], content-length:[29], expires:[mon, 18 feb 2013 20:07:20 gmt], set-cookie:[rps=server52054, jsessionid=6c765c93a085f67d69f800d9eb76646c; path=/], connection:[keep-alive], server:[jabberwacky], rlm:[2416], cache-control:[no-cache;no-store], pragma:[no-cache], date:[mon, 18 feb 2013 19:56:42 gmt], content-type:[text/html;charset=iso-8859-1]] response: denied

again cannot passed response code if seek same on android. can connect root url without path without issue, it's when effort nail path off of root url when eofexception either or post. i've tried moving outputstreamwriter close() phone call toward end can read response code before closing output stream. still eofexception in case. (i've learned experience closing outputstream prematurely in mobile app can shut downwards entire connection.)

Make Camel xslt component use xml catalogs for resolving DTDs -

we utilize camel xslt component transform xhtml file. transforming file, used xmlreader downloads xhtml dtd w3c website.

is possible, tell xslt component, configure xml reader utilize local version (e.g. using xml catalogs)?

i've found way, using processor, creates xmlreader using catalogresolver , puts saxsource using xmlreader exchange.

@override public void process(exchange exchange) throws exception {     inputstream inputstream = exchange.getin().getbody(inputstream.class);      xmlreader xmlreader = xmlreaderfactory.createxmlreader();     xmlreader.setentityresolver(new catalogresolver());     exchange.getin().setbody(new saxsource(xmlreader, new inputsource(inputstream))); }

the transformer used xsltcomponent utilize xmlreader.

java - Why am I getting a "cannot find symbol" error when creating an object? -

when i'm trying create new object class defined, maintain getting "cannot find symbol" error, , there's arrow pointing towards "s" in first "snowfallreport" in constructor. i've had problem when trying create other objects in other programs , wanna throw laptop! sense it's simple solution, don't know is.

the code follows:

import java.util.random;  public class snowfallreport {         // random amount of snow     private double snowamount;      // default constructor creates random amount , assigns snowamount     public void snowfallreport()     {         random snowfall = new random();         snowamount = (snowfall.nextdouble()) * 20;     }      public double getsnow()     {          homecoming snowamount;     }      public void getstars()     {         (int staramount = 0; staramount == snowamount; staramount++)         {             system.out.print("*");         }     }      public static void main(string[] args)     {         **snowfallreport day1 = new snowfallreport();**     } }

java case sensitive language snowfallreport != snowfallreport

your class name snowfallreport create object like:

snowfallreport ref = new snowfallreport ();

also, constructor name should same class name , don't have homecoming type not void.

// default constructor creates random amount , assigns snowamount public void snowfallreport() {

should be

public snowfallreport() {

python - How can I configure ipython to display integers in hex format? -

here's default behavior:

in [21]: 255 out[21]: 255

and here's like:

in [21]: 255 out[21]: ff

can setup ipython that?

you can registering special display formatter ints:

in [1]: formatter = get_ipython().display_formatter.formatters['text/plain']  in [2]: formatter.for_type(int, lambda n, p, cycle: p.text("%x" % n)) out[2]: <function ipython.lib.pretty._repr_pprint>  in [3]: 1 out[3]: 1  in [4]: 100 out[4]: 64  in [5]: 255 out[5]: ff

if want always-on, can create file in $(ipython locate profile)/startup/hexints.py first 2 lines (or 1 avoid assignments):

get_ipython().display_formatter.formatters['text/plain'].for_type(int, lambda n, p, cycle: p.text("%x" % n))

which executed every time start ipython.

node.js - How to insert new tr every third iteration in Jade -

i'm new in node.js , jade.

i searched solutions without success (maybe asked wrong questions in google, don't know).

i want create table rows in each loop in jade. thing after every 3rd td want insert new tr. it's quite simple jade can't accomplish that.

my jade file:

table     thead         tr             td header     tbody         each item, in items             if (i % 3 === 0)             tr                 td                     a(href="#{baseurl}/admin.html?id=#{item.id}")

i know wrong if statement. tried many configurations without luck. i'm sure quite easy issue.

thanks in advance help!

edit

based on @laurent perrin reply modified little code. creates tr, 3 td , new tr it's little closer...

new jade if (i % 3 === 0) tr td: a(href="#{baseurl}/admin.html?id=#{item.id}") dsdsd #{i} generated html <tr></tr> <td><a href="...">0</a></td> <td><a href="...">1</a></td> <td><a href="...">2</a></td> <tr></tr>

edit: code should want, it's not elegant:

table    thead      tr: td header       tbody         - for(var = 0, nbrows = items.length/3; < nbrows; i++) {         tr            if items[3*i]              td: a(href="#{baseurl}/admin.html?id=#{items[3*i].id}")            if items[3*i + 1]              td: a(href="#{baseurl}/admin.html?id=#{items[3*i + 1].id}")            if items[3*i + 2]              td: a(href="#{baseurl}/admin.html?id=#{items[3*i + 2].id}")        - }

what instead tweak model create more jade-friendly, grouping items rows:

function getrows(items) { homecoming items.reduce(function (prev, item, i) { if(i % 3 === 0) prev.push([item]); else prev[prev.length - 1].push(item); homecoming prev; }, []); }

this turn:

[{id:1},{id:2},{id:3},{id:4},{id:5}]

into:

[ [{id:1},{id:2},{id:3}], [{id:4},{id:5}] ]

then jade code becomes much simpler:

table thead tr: td header tbody each row in rows tr each item in row td: a(href="#{baseurl}/admin.html?id=#{item.id}")

filter - How can I show the horizontal scrollbar on a kendo ui grid after filtering? -

i have kendo ui grid many columns. columns overflow can viewed scrolling horizontally. however, if

1) scroll column not displayed and

2) filter on column such no rows match filter criteria

the grid no longer allow scrolling horizontally. column had filter applied cannot cleared.

how can show horizontal scrollbar after such filtering?

here's jsfiddle can see issue

http://jsfiddle.net/9sxkg/1/

here's code:

class="lang-js prettyprint-override">

var dataitem = {}; var columns = [];  (var = 0; < 20; i++) {     dataitem['col' + i] = i;     columns.push( {         field: 'col' + i,         width: 80,         filterable: true,         type: 'number'     } ); }  $("#grid").kendogrid({     scrollable:true,     columns: columns,     filterable: true,     datasource: [dataitem] });

for example, go column 18 , filter on equal 20 see issue.

i had same problem, solved adding empty row grid. code:

class="lang-js prettyprint-override">

var dataitem = {}; var columns = [];  (var = 0; < 20; i++) {   dataitem['col' + i] = i;   columns.push( {     field: 'col' + i,     width: 80,       filterable: true,       type: 'number'   } ); }  $("#grid").kendogrid({     scrollable:true,     columns: columns,     filterable: true,     datasource: [dataitem],     databound: function(e) {           if(this.datasource.view().length == 0) {              var colspan = this.content.find("table col").length;              this.content.find("table").append("<tr><td colspan=" + colspan + "></td></tr>");         }         $("#grid").find(".k-grid-footer-wrap").scrollleft($("#grid").find(".k-grid-content").scrollleft());                 this.content.bind('scroll', function () {             $("#grid").find(".k-grid-footer-wrap").scrollleft(this.scrollleft);         });     } })

Transposing a matrix in C++ -

i'm writing programme transpose given matrix using allocated memory. function works perfect square matrix nxn (rows==cols) crashes mxn matrix (rows != cols). please help

void transpose(int **matrix, int *row, int *col) {     // dynamically allocate array     int **result;     result = new int *[*col]; //creates new array of pointers int objects     // check error     if (result == null)     {         cout << "error allocating array";         exit(1);     }     (int count = 0; count < *col; count++)     {         *(result + count) = new int[*row];     }      // transposing     (int = 0; i<*row; i++)     {        (int j = i+1; j<*col; j++)        {         int temp = *(*(matrix + i) + j);         *(*(matrix + i) + j) = *(*(matrix + j) + i);         *(*(matrix + j) + i) = temp;        }     }      (int = 0; i<*row; i++)     {        (int j = 0; j<*col; j++)        {           *(*(result + i) + j) = *(*(matrix + i) + j);           cout << *(*(result + i) + j) << "\t";        }        cout << endl;     } }

the lines:

for (int = 0; i<*row; i++) {    (int j = i+1; j<*col; j++)    {     int temp = *(*(matrix + i) + j);     *(*(matrix + i) + j) = *(*(matrix + j) + i);     *(*(matrix + j) + i) = temp;    } }

are issue. problem matrix indexed j, not j doing in sec , 3rd line in while loop. image matrix 2x3 matrix, seek perform matrix[2][3] = matrix[3][2], matrix[3][2] not exist.

it best go initializing result straight in loop:

for (int = 0; i<*row; i++) (int j = 0; j<*col; j++) result[j][i] = matrix[i][j];

then can output below, or delete matrix , reassign matrix result wish. entire transpose function became next code (row , col need not pointers int pass value fine. accessing matrices should utilize array subscripts nicer style):

void transpose(int **matrix, int row, int col) {   // dynamically allocate array   int **result;   result = new int *[col]; //creates new array of pointers int objects   (int = 0; < col; i++)     result[i] = new int[row];    // transposing   (int = 0; i<row; i++)    (int j = 0; j<col; j++)      result[j][i] = matrix[i][j];    //output resulting matrix   (int = 0; i<col; i++) {    (int j = 0; j<row; j++)     cout << result[i][j] << "\t";    cout << endl;   } }
