Using an in can have a performance impact. Joining two subqueries will not have the same performance impact and can be accomplished like this:

SELECT *
  FROM (SELECT msisdn
              ,callid
              ,Change_color
              ,play_file_name
              ,date_played
          FROM insert_log
         WHERE play_file_name NOT IN('Prompt1','Conclusion_Prompt_1','silent')
        ORDER BY callid ASC) t1
       JOIN (SELECT MAX(date_played) AS date_played
               FROM insert_log GROUP BY callid) t2
         ON t1.date_played = t2.date_played

From the Sonatype doc:

The answer to this question depends on your own perspective. The great majority of Maven users are going to call Maven a “build tool”: a tool used to build deployable artifacts from source code. Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is focused solely on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team.

I'd strongly recommend looking at the Sonatype doc and spending some time looking at the available plugins to understand the power of Maven.

Very briefly, it operates at a higher conceptual level than (say) Ant. With Ant, you'd specify the set of files and resources that you want to build, then specify how you want them jarred together, and specify the order that should occur in (clean/compile/jar). With Maven this is all implicit. Maven expects to find your files in particular places, and will work automatically with that. Consequently setting up a project with Maven can be a lot simpler, but you have to play by Maven's rules!

If you just want to see the changes in the latest commit, simply git show will give you that.

Something like this should work

var text = $('#toptitle').text();
if (text == 'Profil'){
    $('#toptitle').text('New Word');
}

This work for me

I set style's font before and make rowheader normally then i set in loop for the style with font bolded on each cell of rowhead. Et voilà first row is bolded.

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("FirstSheet");
HSSFRow rowhead = sheet.createRow(0); 
HSSFCellStyle style = wb.createCellStyle();
HSSFFont font = wb.createFont();
font.setFontName(HSSFFont.FONT_ARIAL);
font.setFontHeightInPoints((short)10);
font.setBold(true);
style.setFont(font);
rowhead.createCell(0).setCellValue("ID");
rowhead.createCell(1).setCellValue("First");
rowhead.createCell(2).setCellValue("Second");
rowhead.createCell(3).setCellValue("Third");
for(int j = 0; j<=3; j++)
rowhead.getCell(j).setCellStyle(style);

This will surely work:

UPDATE table1
SET table1.price=(SELECT table2.price
  FROM table2
  WHERE table2.id=table1.id AND table2.item=table1.item);

Here are the primary differences between using System.out/.err/.in and System.console():

• System.console() returns null if your application is not run in a terminal (though you can handle this in your application)
• System.console() provides methods for reading password without echoing characters
• System.out and System.err use the default platform encoding, while the Console class output methods use the console encoding

This latter behaviour may not be immediately obvious, but code like this can demonstrate the difference:

public class ConsoleDemo {
  public static void main(String[] args) {
    String[] data = { "\u250C\u2500\u2500\u2500\u2500\u2500\u2510", 
        "\u2502Hello\u2502",
        "\u2514\u2500\u2500\u2500\u2500\u2500\u2518" };
    for (String s : data) {
      System.out.println(s);
    }
    for (String s : data) {
      System.console().writer().println(s);
    }
  }
}

On my Windows XP which has a system encoding of windows-1252 and a default console encoding of IBM850, this code will write:

???????
?Hello?
???????
+-----+
¦Hello¦
+-----+

Note that this behaviour depends on the console encoding being set to a different encoding to the system encoding. This is the default behaviour on Windows for a bunch of historical reasons.

The your seems a multi-array, not a JSON object.

If you want access the object like an array, you have to use some sort of key/value, such as:

var JSONObject = {
  "city": ["Blankaholm, "Gamleby"],
  "date": ["2012-10-23", "2012-10-22"],
  "description": ["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
  "lat": ["57.586174","16.521841"], 
  "long": ["57.893162","16.406090"]
}

and access it with:

JSONObject.city[0] // => Blankaholm
JSONObject.date[1] // => 2012-10-22

and so on...

or

JSONObject['city'][0] // => Blankaholm
JSONObject['date'][1] // => 2012-10-22

and so on...

or, in last resort, if you don't want change your structure, you can do something like that:

var JSONObject = {
  "data": [
    ["Blankaholm, "Gamleby"],
    ["2012-10-23", "2012-10-22"],
    ["Blankaholm. Under natten har det varit inbrott", "E22 i med Gamleby. Singelolycka. En bilist har.],
    ["57.586174","16.521841"], 
    ["57.893162","16.406090"]
  ]
}

JSONObject.data[0][1] // => Gambleby

My recipe has three steps:

1. to install material-design-icons package

   npm install material-design-icons
   

2. to import material-icons.css file into .less or .scss file/ project

   @import "~/node_modules/material-design-icons/iconfont/material-icons.css";
   

3. to include recommended code into the reactjs .js file/ project

   <i className='material-icons' style={{fontSize: '36px'}}>close</i>
   

Here is another, very manual solution. You can define the size of the axis and paddings are considered accordingly (including legend and tickmarks). Hope it is of use to somebody.

Example (axes size are the same!):

Code:

#==================================================
# Plot table

colmap = [(0,0,1) #blue
         ,(1,0,0) #red
         ,(0,1,0) #green
         ,(1,1,0) #yellow
         ,(1,0,1) #magenta
         ,(1,0.5,0.5) #pink
         ,(0.5,0.5,0.5) #gray
         ,(0.5,0,0) #brown
         ,(1,0.5,0) #orange
         ]

#--------------------------------------------------

fig.tight_layout() #tight margins

I would suggest you to use Origami. Its a great plugin for splitting the screen. For better information on keyboard short cuts install it and after restarting Sublime text open Preferences->Package Settings -> Origami -> Key Bindings - Default

For specific to your question I would suggest you to see the short cuts related to cloning of files in the above mentioned file.

For most it is a breeze, however like you I had a difficult time installing jq

The best resources I found are: https://stedolan.github.io/jq/download/ and http://macappstore.org/jq/

However neither worked for me. I run python 2 & 3, and use brew in addition to pip, as well as Jupyter. I was only successful after brew uninstall jq then updating brew and rebooting my system

What worked for me was removing all previous installs then pip install jq

You need to add a dataType - http://api.jquery.com/jQuery.ajax/

$(document).ready(function() {
    $("#lesen").click(function() {
        $.ajax({
            url : "helloworld.txt",
            dataType: "text",
            success : function (data) {
                $(".text").html(data);
            }
        });
    });
}); 

Here is the simplest way to do it with CSS3:

#mybox:hover {
  color: transparent;
}

regardless of the container color you can make the text color transparent on hover.

Cheers! :)

When embedding same-origin SVGs using <object>, you can access the internal contents using objectElement.contentDocument.rootElement. From there, you can easily attach event handlers (e.g. via onclick, addEventListener(), etc.)

For example:

var object = /* get DOM node for <object> */;
var svg = object.contentDocument.rootElement;
svg.addEventListener('click', function() {
  console.log('hooray!');
});

Note that this is not possible for cross-origin <object> elements unless you also control the <object> origin server and can set CORS headers there. For cross-origin cases without CORS headers, access to contentDocument is blocked.

select * from all_constraints
where owner = '<NAME>'
and constraint_name = 'SYS_C00381400'
/

Like all data dictionary views, this a USER_CONSTRAINTS view if you just want to check your current schema and a DBA_CONSTRAINTS view for administration users.

The construction of the constraint name indicates a system generated constraint name. For instance, if we specify NOT NULL in a table declaration. Or indeed a primary or unique key. For example:

SQL> create table t23 (id number not null primary key)
  2  /

Table created.

SQL> select constraint_name, constraint_type
  2  from user_constraints
  3  where table_name = 'T23'
  4  /

CONSTRAINT_NAME                C
------------------------------ -
SYS_C00935190                  C
SYS_C00935191                  P

SQL>

'C' for check, 'P' for primary.

Generally it's a good idea to give relational constraints an explicit name. For instance, if the database creates an index for the primary key (which it will do if that column is not already indexed) it will use the constraint name oo name the index. You don't want a database full of indexes named like SYS_C00935191.

To be honest most people don't bother naming NOT NULL constraints.

With Tortoise SVN:

If you haven't committed your changes yet, you can do a revert on the parent folder where you deleted the file or directory.

If you have already committed the deleted file, then you can use the repository browser, change to the revision where the file still existed and then use the command Copy to... from the context menu. Enter the path to your working copy as the target and the deleted file will be copied from the repository to your working copy.

Try this:

<?php
    $str = "This is some <b>bold</b> text.";
    echo htmlspecialchars($str);
?>

Use strtol if you have libc available like the top answer suggests. However if you like custom stuff or are on a microcontroller without libc or so, you may want a slightly optimized version without complex branching.

#include <inttypes.h>


/**
 * xtou64
 * Take a hex string and convert it to a 64bit number (max 16 hex digits).
 * The string must only contain digits and valid hex characters.
 */
uint64_t xtou64(const char *str)
{
    uint64_t res = 0;
    char c;

    while ((c = *str++)) {
        char v = (c & 0xF) + (c >> 6) | ((c >> 3) & 0x8);
        res = (res << 4) | (uint64_t) v;
    }

    return res;
} 

The bit shifting magic boils down to: Just use the last 4 bits, but if it is an non digit, then also add 9.

Another useful way is with Concat.
More information in the official documentation.

List<string> first = new List<string> { "One", "Two", "Three" };
List<string> second = new List<string>() { "Four", "Five" };
first.Concat(second);

The output will be.

One
Two
Three
Four
Five

And there is another similar answer.

Let'e me give an example:

1. client connect to server, and send 1MB data to server every 1 second.

2. server side accept a connection, and then sleep 20 second, without recv msg from client.So the tcp send buffer in the client side will be full.

Code in client side:

#include <arpa/inet.h>
#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <stdlib.h>
#include <string.h>
#define exit_if(r, ...)                                                                          \
    if (r) {                                                                                     \
        printf(__VA_ARGS__);                                                                     \
        printf("%s:%d error no: %d error msg %s\n", __FILE__, __LINE__, errno, strerror(errno)); \
        exit(1);                                                                                 \
    }

void setNonBlock(int fd) {
    int flags = fcntl(fd, F_GETFL, 0);
    exit_if(flags < 0, "fcntl failed");
    int r = fcntl(fd, F_SETFL, flags | O_NONBLOCK);
    exit_if(r < 0, "fcntl failed");
}

void test_full_sock_buf_1(){
    short port = 8000;
    struct sockaddr_in addr;
    memset(&addr, 0, sizeof addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;


    int fd = socket(AF_INET, SOCK_STREAM, 0);
    exit_if(fd<0, "create socket error");

    int ret = connect(fd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(ret<0, "connect to server error");
    setNonBlock(fd);

    printf("connect to server success");

    const int LEN = 1024 * 1000;
    char msg[LEN];  // 1MB data
    memset(msg, 'a', LEN);

    for (int i = 0; i < 1000; ++i) {
        int len = send(fd, msg, LEN, 0);
        printf("send: %d, erron: %d, %s \n", len, errno, strerror(errno));
        sleep(1);
    }

}

int main(){
    test_full_sock_buf_1();

    return 0;
}

Code in server side:

    #include <arpa/inet.h>
    #include <sys/socket.h>
    #include <stdio.h>
    #include <errno.h>
    #include <fcntl.h>
    #include <stdlib.h>
    #include <string.h>
    #define exit_if(r, ...)                                                                          \
        if (r) {                                                                                     \
            printf(__VA_ARGS__);                                                                     \
            printf("%s:%d error no: %d error msg %s\n", __FILE__, __LINE__, errno, strerror(errno)); \
            exit(1);                                                                                 \
        }
void test_full_sock_buf_1(){

    int listenfd = socket(AF_INET, SOCK_STREAM, 0);
    exit_if(listenfd<0, "create socket error");

    short port = 8000;
    struct sockaddr_in addr;
    memset(&addr, 0, sizeof addr);
    addr.sin_family = AF_INET;
    addr.sin_port = htons(port);
    addr.sin_addr.s_addr = INADDR_ANY;

    int r = ::bind(listenfd, (struct sockaddr *) &addr, sizeof(struct sockaddr));
    exit_if(r<0, "bind socket error");

    r = listen(listenfd, 100);
    exit_if(r<0, "listen socket error");

    struct sockaddr_in raddr;
    socklen_t rsz = sizeof(raddr);
    int cfd = accept(listenfd, (struct sockaddr *) &raddr, &rsz);
    exit_if(cfd<0, "accept socket error");

    sockaddr_in peer;
    socklen_t alen = sizeof(peer);
    getpeername(cfd, (sockaddr *) &peer, &alen);

    printf("accept a connection from %s:%d\n", inet_ntoa(peer.sin_addr), ntohs(peer.sin_port));

    printf("but now I will sleep 15 second, then exit");
    sleep(15);
}

Start server side, then start client side.

server side may output:

accept a connection from 127.0.0.1:35764
but now I will sleep 15 second, then exit
Process finished with exit code 0

client side may output:

connect to server successsend: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success 
send: 1024000, erron: 0, Success

send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 
send: -1, erron: 32, Broken pipe 

You can see, as the server side doesn't recv the data from client, so when the client side tcp buffer get full, but you still send data, so you may get Resource temporarily unavailable error.

I recommend the accepted answer above. If you are in a pinch, however, you could declare the object as a global within the page_properties function.

$objPage = new PageAtrributes;

function page_properties() {
    global $objPage;
    $objPage->set_page_title($myrow['title']);
}

var newElementsAppended = $(newHtml).appendTo("#myDiv");
newElementsAppended.effects("highlight", {}, 2000);

use filter to remove empty string in array.

var s = [ '1,201,karthikeyan,K201,HELPER,[email protected],8248606269,7/14/2017,45680,TN-KAR24,8,800,1000,200,300,Karthikeyan,11/24/2017,Karthikeyan,11/24/2017,AVAILABLE\r',_x000D_
  '' ]_x000D_
var newArr = s.filter(function(entry) { return entry.trim() != ''; })_x000D_
_x000D_
console.log(newArr); 

You weren't far from the result! This does it:

awk '{NF--; print $NF}' file

This decrements the number of fields in one, so that $NF contains the former penultimate.

Test

Let's generate some numbers and print them on groups of 5:

$ seq 12 | xargs -n5
1 2 3 4 5
6 7 8 9 10
11 12

Let's print the penultimate on each line:

$ seq 12 | xargs -n5 | awk '{NF--; print $NF}'
4
9
11

Here is a function that will flatten an object or array. Use this only if you are sure your keys are unique. If you have keys with the same name they will be overwritten. You will need to place this in a class and replace "Functions" with the name of your class. Enjoy...

function flatten($array, $preserve_keys=1, &$out = array(), $isobject=0) {
        # Flatten a multidimensional array to one dimension, optionally preserving keys.
        #
        # $array - the array to flatten
        # $preserve_keys - 0 (default) to not preserve keys, 1 to preserve string keys only, 2 to preserve all keys
        # $out - internal use argument for recursion
        # $isobject - is internally set in order to remember if we're using an object or array
        if(is_array($array) || $isobject==1)
        foreach($array as $key => $child)
            if(is_array($child))
                $out = Functions::flatten($child, $preserve_keys, $out, 1); // replace "Functions" with the name of your class
            elseif($preserve_keys + is_string($key) > 1)
                $out[$key] = $child;
            else
                $out[] = $child;

        if(is_object($array) || $isobject==2)
        if(!is_object($out)){$out = new stdClass();}
        foreach($array as $key => $child)
            if(is_object($child))
                $out = Functions::flatten($child, $preserve_keys, $out, 2); // replace "Functions" with the name of your class
            elseif($preserve_keys + is_string($key) > 1)
                $out->$key = $child;
            else
                $out = $child;

        return $out;
}

I copied the current files in a different folder, then get rid of all unpushed changes by:

git reset --hard @{u}

Then copy things back. Commit, Push.

One way of doing this is using Html tags::

txtTitlevalue.setText(Html.fromHtml("Line1"+"<br>"+"Line2" + " <br>"+"Line3"));

rake routes | grep <specific resource name>

displays resource specific routes, if it is a pretty long list of routes.

As answered by RafaelC, Python 3 renamed dict.iteritems -> dict.items. Try a different package version. This will list available packages:

python -m pip install yourOwnPackageHere==

Then rerun with the version you will try after == to install/switch version

I defined own helper function to convert timedelta object to 'HH:MM:SS' format - only hours, minutes and seconds, without changing hours to days.

def format_timedelta(td):
    hours, remainder = divmod(td.total_seconds(), 3600)
    minutes, seconds = divmod(remainder, 60)
    hours, minutes, seconds = int(hours), int(minutes), int(seconds)
    if hours < 10:
        hours = '0%s' % int(hours)
    if minutes < 10:
        minutes = '0%s' % minutes
    if seconds < 10:
        seconds = '0%s' % seconds
    return '%s:%s:%s' % (hours, minutes, seconds)

The correct php way is to use parse_url()

http://php.net/manual/en/function.parse-url.php

(from php manual)

This function parses a URL and returns an associative array containing any of the various components of the URL that are present.

This function is not meant to validate the given URL, it only breaks it up into the above listed parts. Partial URLs are also accepted, parse_url() tries its best to parse them correctly.

I'm using

Sheet1.Range("E2", "E3000").NumberFormat = "dd/mm/yyyy hh:mm:ss"

to format a column

So I guess

Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"

would do the trick for you.

More: NumberFormat function.

You can also do this using DOM Level 2 CSS interfaces (MDN):

var sheet = window.document.styleSheets[0];
sheet.insertRule('strong { color: red; }', sheet.cssRules.length);

...on all but (naturally) IE8 and prior, which uses its own marginally-different wording:

sheet.addRule('strong', 'color: red;', -1);

There is a theoretical advantage in this compared to the createElement-set-innerHTML method, in that you don't have to worry about putting special HTML characters in the innerHTML, but in practice style elements are CDATA in legacy HTML, and ‘<’ and ‘&’ are rarely used in stylesheets anyway.

You do need a stylesheet in place before you can started appending to it like this. That can be any existing active stylesheet: external, embedded or empty, it doesn't matter. If there isn't one, the only standard way to create it at the moment is with createElement.

Trying to solve this problem myself, I discovered that there is no HeadBucket permission. It looks like there is, because that's what the error message tells you, but actually the HEAD operation requires the ListBucket permission. I also discovered that my IAM policy and my bucket policy were conflicting. Make sure you check both.

col-xs-* have been dropped in Bootstrap 4 in favor of col-*.

Replace col-xs-12 with col-12 and it will work as expected.

Also note col-xs-offset-{n} were replaced by offset-{n} in v4.

That's really an informational message.

Likely, you're doing OPTIMIZE on an InnoDB table (table using the InnoDB storage engine, rather than the MyISAM storage engine).

InnoDB doesn't support the OPTIMIZE the way MyISAM does. It does something different. It creates an empty table, and copies all of the rows from the existing table into it, and essentially deletes the old table and renames the new table, and then runs an ANALYZE to gather statistics. That's the closest that InnoDB can get to doing an OPTIMIZE.

The message you are getting is basically MySQL server repeating what the InnoDB storage engine told MySQL server:

Table does not support optimize is the InnoDB storage engine saying...

"I (the InnoDB storage engine) don't do an OPTIMIZE operation like my friend (the MyISAM storage engine) does."

"doing recreate + analyze instead" is the InnoDB storage engine saying...

"I have decided to perform a different set of operations which will achieve an equivalent result."

Instead of using the "c" tags, you could also do the following:

<h:outputLink value="Images/thumb_02.jpg" target="_blank" rendered="#{not empty user or user.userId eq 0}" />
<h:graphicImage value="Images/thumb_02.jpg" rendered="#{not empty user or user.userId eq 0}" />

<h:outputLink value="/DisplayBlobExample?userId=#{user.userId}" target="_blank" rendered="#{not empty user and user.userId neq 0}" />
<h:graphicImage value="/DisplayBlobExample?userId=#{user.userId}" rendered="#{not empty user and user.userId neq 0}"/>

I think that's a little more readable alternative to skuntsel's alternative answer and is utilizing the JSF rendered attribute instead of nesting a ternary operator. And off the answer, did you possibly mean to put your image in between the anchor tags so the image is clickable?

If you want to replace NAs in factor variables, this might be useful:

n <- length(levels(data.vector))+1

data.vector <- as.numeric(data.vector)
data.vector[is.na(data.vector)] <- n
data.vector <- as.factor(data.vector)
levels(data.vector) <- c("level1","level2",...,"leveln", "NAlevel") 

It transforms a factor-vector into a numeric vector and adds another artifical numeric factor level, which is then transformed back to a factor-vector with one extra "NA-level" of your choice.

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

It's not a direct answer on question (its not about Actions), but it also allow you to scroll easily to required element:

element = driver.find_element_by_id('some_id')
element.location_once_scrolled_into_view

This actually intend to return you coordinates (x, y) of element on page, but also scroll down right to target element

So far as my observation goes, any answer posted here can have unexpected side effects.

In ES2015-compatible enviroment, you can avoid any side effects by using WeakMap.

const id = (() => {
    let currentId = 0;
    const map = new WeakMap();

    return (object) => {
        if (!map.has(object)) {
            map.set(object, ++currentId);
        }

        return map.get(object);
    };
})();

id({}); //=> 1

You can accomplish this in a very back-handed way with the following code:

exports.getStaticCompanies = function () {
    var ids = [46128, 2865, 49569, 1488, 45600, 61991, 1418, 61919, 53326, 61680]
    return Company.findAll({
        where: {
            id: ids
        },
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at'],
        order: sequelize.literal('(' + ids.map(function(id) {
            return '"Company"."id" = \'' + id + '\'');
        }).join(', ') + ') DESC')
    });
};

This is somewhat limited because it's got very bad performance characteristics past a few dozen records, but it's acceptable at the scale you're using.

This will produce a SQL query that looks something like this:

[...] ORDER BY ("Company"."id"='46128', "Company"."id"='2865', "Company"."id"='49569', [...])

@Asiddeen bn Muhammad's solution worked for me with a little modification to the css

I use a couple of functions that I wrote a while back to generate the xml to pass back and forth from PHP and jQuery etc... Neither use any additional frameworks just purely generates a string that can then be used with SimpleXML (or other framework)...

If it's useful to anyone, please use it :)

function generateXML($tag_in,$value_in="",$attribute_in=""){
    $return = "";
    $attributes_out = "";
    if (is_array($attribute_in)){
        if (count($attribute_in) != 0){
            foreach($attribute_in as $k=>$v):
                $attributes_out .= " ".$k."=\"".$v."\"";
            endforeach;
        }
    }
    return "<".$tag_in."".$attributes_out.((trim($value_in) == "") ? "/>" : ">".$value_in."</".$tag_in.">" );
}

function arrayToXML($array_in){
    $return = "";
    $attributes = array();
    foreach($array_in as $k=>$v):
        if ($k[0] == "@"){
            // attribute...
            $attributes[str_replace("@","",$k)] = $v;
        } else {
            if (is_array($v)){
                $return .= generateXML($k,arrayToXML($v),$attributes);
                $attributes = array();
            } else if (is_bool($v)) {
                $return .= generateXML($k,(($v==true)? "true" : "false"),$attributes);
                $attributes = array();
            } else {
                $return .= generateXML($k,$v,$attributes);
                $attributes = array();
            }
        }
    endforeach;
    return $return;
}

$ls -l `which sh`

Then it will be OK

On your terminal, try running:

which -a ruby

This will output all the installed Ruby versions (via RVM, or otherwise) on your system in your PATH. If 1.8.7 is your system Ruby version, you can uninstall the system Ruby using:

sudo apt-get purge ruby

Once you have made sure you have Ruby installed via RVM alone, in your login shell you can type:

rvm --default use 2.0.0

You don't need to do this if you have only one Ruby version installed.

If you still face issues with any system Ruby files, try running:

dpkg-query -l '*ruby*'

This will output a bunch of Ruby-related files and packages which are, or were, installed on your system at the system level. Check the status of each to find if any of them is native and is causing issues.

for bootstrap 4

add classes :

  min-height: 92% !important;
  max-width: 98% !important;
  max-height: 92% !important;
  padding: 0 !important;
}

.full_modal-content {
  height: 99% !important;
  min-height: 99% !important;
  max-height: 99% !important;
}

and in HTML :

<div role="document" class="modal-dialog full_modal-dialog">
    <div class="modal-content full_modal-content">

Here, for OS X completeness: if you install PostgreSQL from MacPorts, pg_config will be in /opt/local/lib/postgresql94/bin/pg_config.

When you installed MacPorts, it already added /opt/local/bin to your PATH.

So, this will fix the problem: $ sudo ln -s /opt/local/lib/postgresql94/bin/pg_config /opt/local/bin/pg_config

Now pip install psycopg2 will be able to run pg_config without issues.

You can render the dependency tree with the command gradle dependencies. For more information check the section 11.6.4 Listing project dependencies in the online user guide.

I've just come across this, and thought I'd add my thoughts. As others have suggested, I'd recommend manually adding IDs, but if you really want something close to what you've described, you could use this:

var objectId = (function () {
    var allObjects = [];

    var f = function(obj) {
        if (allObjects.indexOf(obj) === -1) {
            allObjects.push(obj);
        }
        return allObjects.indexOf(obj);
    }
    f.clear = function() {
      allObjects = [];
    };
    return f;
})();

You can get any object's ID by calling objectId(obj). Then if you want the id to be a property of the object, you can either extend the prototype:

Object.prototype.id = function () {
    return objectId(this);
}

or you can manually add an ID to each object by adding a similar function as a method.

The major caveat is that this will prevent the garbage collector from destroying objects when they drop out of scope... they will never drop out of the scope of the allObjects array, so you might find memory leaks are an issue. If your set on using this method, you should do so for debugging purpose only. When needed, you can do objectId.clear() to clear the allObjects and let the GC do its job (but from that point the object ids will all be reset).

Here's my webpack 4 + font awesome 5 solution:

    src: url('/font-awesome/fontawesome-webfont.eot?#iefix') format('embedded-opentype'),
    url('/font-awesome/fontawesome-webfont.woff2') format('woff2'),
    url('/font-awesome/fontawesome-webfont.woff') format('woff'),

If you don't care about the order of the K-th largest elements you can use argpartition, which should perform better than a full sort through argsort.

K = 4 # We want the indices of the four largest values
a = np.array([0, 8, 0, 4, 5, 8, 8, 0, 4, 2])
np.argpartition(a,-K)[-K:]
array([4, 1, 5, 6])

Credits go to this question.

I ran a few tests and it looks like argpartition outperforms argsort as the size of the array and the value of K increase.

Dietel and Dietel have a nice way of explaining fields vs variables.

“Together a class’s static variables and instance variables are known as its fields.” (Section 6.3)

“Variables should be declared as fields only if they’re required for use in more than one method of the class or if the program should save their values between calls to the class’s methods.” (Section 6.4)

So a class's fields are its static or instance variables - i.e. declared with class scope.

Step1 (inside command prompt [I hope you cd TO YOUR FOLDER]) : npm install express

Step 2: Create a file server.js

var fs = require("fs");
var host = "127.0.0.1";
var port = 1337;
var express = require("express");

var app = express();
app.use(express.static(__dirname + "/public")); //use static files in ROOT/public folder

app.get("/", function(request, response){ //root dir
    response.send("Hello!!");
});

app.listen(port, host);

Please note, you should add WATCHFILE (or use nodemon) too. Above code is only for a simple connection server.

STEP 3: node server.js or nodemon server.js

There is now more easy method if you just want host simple HTTP server. npm install -g http-server

and open our directory and type http-server

99% of the time, you should not have to worry about either. :) But, if your objects hold references to non-managed resources (window handles, file handles, for example), you need to provide a way for your managed object to release those resources. Finalize gives implicit control over releasing resources. It is called by the garbage collector. Dispose is a way to give explicit control over a release of resources and can be called directly.

There is much much more to learn about the subject of Garbage Collection, but that's a start.

But now it is not working and I contacted our hosting team then they told me to use smtp

Newsflash - it was using SMTP before. They've not provided you with the information you need to solve the problem - or you've not relayed it accurately here.

Its possible that they've disabled the local MTA on the webserver, in which case you'll need to connect the SMTP port on a remote machine. There are lots of toolkits which will do the heavy lifting for you. Personally I like phpmailer because it adds other functionality.

Certainly if they've taken away a facility which was there before and your paying for a service then your provider should be giving you better support than that (there are also lots of programs to drop in in place of a full MTA which would do the job).

C.

It's also possible to use java Foo | tee -a some.log. it just prints to stdout as well. Like:

user at Computer in ~
$ echo "hi" | tee -a foo.txt
hi

user at Computer in ~
$ echo "hello" | tee -a foo.txt
hello

user at Computer in ~
$ cat foo.txt
hi
hello

If you order a vector x, and find the values that is half way through the vector, you just found a median, or 50th percentile. Same logic applies for any percentage. Here are two examples.

x <- rnorm(100)
quantile(x, probs = c(0, 0.25, 0.5, 0.75, 1)) # quartile
quantile(x, probs = seq(0, 1, by= 0.1)) # decile

reinterpret_cast

my rule of thumb is:

rebase for branches with the same name, merge otherwise.

examples for same names would be master, origin/master and otherRemote/master.

if develop exists only in the local repository, and it is always based on a recent origin/master commit, you should call it master, and work there directly. it simplifies your life, and presents things as they actually are: you are directly developing on the master branch.

if develop is shared, it should not be rebased on master, just merged back into it with --no-ff. you are developing on develop. master and develop have different names, because we want them to be different things, and stay separate. do not make them same with rebase.

See if this is what you want to do:

Here's a method you can use to rotate an image in C#:

/// <summary>
/// method to rotate an image either clockwise or counter-clockwise
/// </summary>
/// <param name="img">the image to be rotated</param>
/// <param name="rotationAngle">the angle (in degrees).
/// NOTE:

armhf stands for "arm hard float", and is the name given to a debian port for arm processors (armv7+) that have hardware floating point support.

On the beaglebone black, for example:

:~$ dpkg --print-architecture
armhf

Although other commands (such as uname -a or arch) will just show armv7l

:~$ cat /proc/cpuinfo 
processor       : 0
model name      : ARMv7 Processor rev 2 (v7l)
BogoMIPS        : 995.32
Features        : half thumb fastmult vfp edsp thumbee neon vfpv3 tls
...

The vfpv3 listed under Features is what refers to the floating point support.

Incidentally, armhf, if your processor supports it, basically supersedes Raspbian, which if I understand correctly was mainly a rebuild of armhf with work arounds to deal with the lack of floating point support on the original raspberry pi's. Nowdays, of course, there's a whole ecosystem build up around Raspbian, so they're probably not going to abandon it. However, this is partly why the beaglebone runs straight debian, and that's ok even if you're used to Raspbian, unless you want some of the special included non-free software such as Mathematica.

As Ponies says in a comment, you cannot mix OLAP functions with aggregate functions.

Perhaps it's easier to get the last completion date for each employee, and join that to a dataset containing the last completion date for each of the three targeted courses.

This is an untested idea that should hopefully put you down the right path:

  SELECT employee_number,
         course_code,
         MAX(course_completion_date) AS max_date,
         lcc.LAST_COURSE_COMPLETED
    FROM employee_course_completion ecc
         LEFT JOIN (
             SELECT employee_number,
                    MAX(course_completion_date) AS LAST_COURSE_COMPLETED
               FROM employee_course_completion
              WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
         ) lcc
         ON lcc.employee_number = ecc.employee_number
   WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code, lcc.LAST_COURSE_COMPLETED

Try this:

MyContext Context = new MyContext(); 
Context.YourEntity.Add(obj);
Context.SaveChanges();
int ID = obj._ID;

Here is another option.

os.scandir(path='.')

It returns an iterator of os.DirEntry objects corresponding to the entries (along with file attribute information) in the directory given by path.

Example:

with os.scandir(path) as it:
    for entry in it:
        if not entry.name.startswith('.'):
            print(entry.name)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

The size of the pointer basically depends on the architecture of the system in which it is implemented. For example the size of a pointer in 32 bit is 4 bytes (32 bit ) and 8 bytes(64 bit ) in a 64 bit machines. The bit types in a machine are nothing but memory address, that it can have. 32 bit machines can have 2^32 address space and 64 bit machines can have upto 2^64 address spaces. So a pointer (variable which points to a memory location) should be able to point to any of the memory address (2^32 for 32 bit and 2^64 for 64 bit) that a machines holds.

Because of this reason we see the size of a pointer to be 4 bytes in 32 bit machine and 8 bytes in a 64 bit machine.

This is how you Delete From a slice the idiomatic way. You don't need to build a function it is built into the append. Try it here https://play.golang.org/p/QMXn9-6gU5P

z := []int{9, 8, 7, 6, 5, 3, 2, 1, 0}
fmt.Println(z)  //will print Answer [9 8 7 6 5 3 2 1 0]

z = append(z[:2], z[4:]...)
fmt.Println(z)   //will print Answer [9 8 5 3 2 1 0]

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

In short, yes.

Suppose we are on a 32-bit machine.

If it is little endian, the x in the memory will be something like:

       higher memory
          ----->
    +----+----+----+----+
    |0x01|0x00|0x00|0x00|
    +----+----+----+----+
    A
    |
   &x

so (char*)(&x) == 1, and *y+48 == '1'.

If it is big endian, it will be:

    +----+----+----+----+
    |0x00|0x00|0x00|0x01|
    +----+----+----+----+
    A
    |
   &x

so this one will be '0'.

Some general notes.

$obj | Select-Object ? $obj | Select-Object -Property *

The latter will show all non-intrinsic, non-compiler-generated properties. The former does not appear to (always) show all Property types (in my tests, it does appear to show the CodeProperty MemberType consistently though -- no guarantees here).

Some switches to be aware of for Get-Member

• Get-Member does not get static members by default. You also cannot (directly) get them along with the non-static members. That is, using the switch causes only static members to be returned:
  

  PS Y:\Power> $obj | Get-Member -Static
  
     TypeName: System.IsFire.TurnUpProtocol
  
  Name        MemberType Definition
  ----        ---------- ----------
  Equals      Method     static bool Equals(System.Object objA, System.Object objB)
  ...
  

• Use the -Force.

  The Get-Member command uses the Force parameter to add the intrinsic members and compiler-generated members of the objects to the display. Get-Member gets these members, but it hides them by default.

  PS Y:\Power> $obj | Get-Member -Static
  
     TypeName: System.IsFire.TurnUpProtocol
  
  Name          MemberType     Definition
  ----          ----------     ----------
  ...
  pstypenames   CodeProperty   System.Collections.ObjectModel.Collection...
  psadapted     MemberSet      psadapted {AccessRightType, AccessRuleType,...
  ...
  

Use ConvertTo-Json for depth and readable "serialization"

I do not necessary recommend saving objects using JSON (use Export-Clixml instead). However, you can get a more or less readable output from ConvertTo-Json, which also allows you to specify depth.

Note that not specifying Depth implies -Depth 2

PS Y:\Power> ConvertTo-Json $obj -Depth 1
{
    "AllowSystemOverload":  true,
    "AllowLifeToGetInTheWay":  false,
    "CantAnyMore": true,
    "LastResortOnly": true,
...

And if you aren't planning to read it you can -Compress it (i.e. strip whitespace)

PS Y:\Power> ConvertTo-Json $obj -Depth 420 -Compress

Use -InputObject if you can (and are willing)

99.9% of the time when using PowerShell: either the performance won't matter, or you don't care about the performance. However, it should be noted that avoiding the pipe when you don't need it can save some overhead and add some speed (piping, in general, is not super-efficient).

That is, if you all you have is a single $obj handy for printing (and aren't too lazy like me sometimes to type out -InputObject):

# select is aliased (hardcoded) to Select-Object
PS Y:\Power> select -Property * -InputObject $obj

# gm is aliased (hardcoded) to Get-Member
PS Y:\Power> gm -Force -InputObject $obj

Caveat for Get-Member -InputObject: If $obj is a collection (e.g. System.Object[]), You end up getting information about the collection object itself:

PS Y:\Power> gm -InputObject $obj,$obj2
   TypeName: System.Object[]

Name        MemberType            Definition
----        ----------            ----------
Count       AliasProperty         Count = Length
...

If you want to Get-Member for each TypeName in the collection (N.B. for each TypeName, not for each object--a collection of N objects with all the same TypeName will only print 1 table for that TypeName, not N tables for each object)......just stick with piping it in directly.

If you are using the table interface you can type in NULL (all caps)

otherwise you can run an update statement where you could:

Update table set ColumnName = NULL where [Filter for record here]

assertTrue will fail if the checked value is false, and assertFalse will do the opposite: fail if the checked value is true.

Another thing, your last assertEquals will very likely fail, as it will compare the "Book was already checked out" string with the output of m1.checkOut(b1,p2). It needs a third parameter (the second value to check for equality).

I see two parts to this:

1. "What exactly is Spring for" -> see the accepted answer by victor hugo.
2. "[...] Spring is [a] good framework for web development" -> people saying this are talking about Spring MVC. Spring MVC is one of the many parts of Spring, and is a web framework making use of the general features of Spring, like dependency injection. It's a pretty generic framework in that it is very configurable: you can use different db layers (Hibernate, iBatis, plain JDBC), different view layers (JSP, Velocity, Freemarker...)

Note that you can perfectly well use Spring in a web application without using Spring MVC. I would say most Java web applications do this, while using other web frameworks like Wicket, Struts, Seam, ...

@SC_Chupacabra has correct answer for modifying behavior.

I generally prefer CTRL + PAGE UP / DOWN for my navigation, rather than using the TAB key.

    {
        "key": "ctrl+pageUp",
        "command": "workbench.action.nextEditor"
    },
    {
        "key": "ctrl+pageDown",
        "command": "workbench.action.previousEditor"
    }

Probably the easiest and most efficient way is to use boost and the boost::filesystem functions. This way you can build a directory simply and ensure that it is platform independent.

const char* path = _filePath.c_str();
boost::filesystem::path dir(path);
if(boost::filesystem::create_directory(dir))
{
    std::cerr<< "Directory Created: "<<_filePath<<std::endl;
}

boost::filesystem::create_directory - documentation

Is it because some culture format issue?

Yes. Your user must be in a culture where the time separator is a dot. Both ":" and "/" are interpreted in a culture-sensitive way in custom date and time formats.

How can I make sure the result string is delimited by colon instead of dot?

I'd suggest specifying CultureInfo.InvariantCulture:

string text = dateTime.ToString("MM/dd/yyyy HH:mm:ss.fff",
                                CultureInfo.InvariantCulture);

Alternatively, you could just quote the time and date separators:

string text = dateTime.ToString("MM'/'dd'/'yyyy HH':'mm':'ss.fff");

... but that will give you "interesting" results that you probably don't expect if you get users running in a culture where the default calendar system isn't the Gregorian calendar. For example, take the following code:

using System;
using System.Globalization;
using System.Threading;

class Test
{
    static void Main()        
    {
        DateTime now = DateTime.Now;
        CultureInfo culture = new CultureInfo("ar-SA"); // Saudi Arabia
        Thread.CurrentThread.CurrentCulture = culture;
        Console.WriteLine(now.ToString("yyyy-MM-ddTHH:mm:ss.fff"));
    }
} 

That produces output (on September 18th 2013) of:

11/12/1434 15:04:31.750

My guess is that your web service would be surprised by that!

I'd actually suggest not only using the invariant culture, but also changing to an ISO-8601 date format:

string text = dateTime.ToString("yyyy-MM-ddTHH:mm:ss.fff");

This is a more globally-accepted format - it's also sortable, and makes the month and day order obvious. (Whereas 06/07/2013 could be interpreted as June 7th or July 6th depending on the reader's culture.)

i am using centos and getting same error when run mvn command with goal, install. After some googling i have found the solution to run following command.

sudo yum install java-1.8.0-openjdk-devel

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

From Jeffery Hicks Aarticle

Other answers address the arguments.

I know this is a pretty old thread, but I was searching for something similar and came up with this.

Given that you had a comma-separated string, you could use string_split

select distinct value from string_split('1, 1, 1, 2, 5, 1, 6',',')

This should return

1
2
5
6

String split takes two parameters, the string input, and the separator character.

you can add an optional where statement using value as the column name

select distinct value from string_split('1, 1, 1, 2, 5, 1, 6',',')
where value > 1

produces

2
5
6

I don't know if I got it right, but does this solve your problem?

Inside of any Activity class you create a method that will assign NULL to thread instance which can be used as an alternative to the depreciated stop() method for stopping thread execution:

public class MyActivity extends Activity {

private Thread mThread;  

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


        mThread =  new Thread(){
        @Override
        public void run(){
            // Perform thread commands...
    for (int i=0; i < 5000; i++)
    {
      // do something...
    }

    // Call the stopThread() method.
            stopThread(this);
          }
        };

    // Start the thread.
        mThread.start(); 
}

private synchronized void stopThread(Thread theThread)
{
    if (theThread != null)
    {
        theThread = null;
    }
}
}

This works for me without a problem.

Your best option will be to create a simple data structure to model what you have. Then you can store these objects in a simple list and sort/retrieve them any way you wish.

For this case, I'd use the following class:

class Fruit:
    def __init__(self, name, color, quantity): 
        self.name = name
        self.color = color
        self.quantity = quantity

    def __str__(self):
        return "Name: %s, Color: %s, Quantity: %s" % \
     (self.name, self.color, self.quantity)

Then you can simply construct "Fruit" instances and add them to a list, as shown in the following manner:

fruit1 = Fruit("apple", "red", 12)
fruit2 = Fruit("pear", "green", 22)
fruit3 = Fruit("banana", "yellow", 32)
fruits = [fruit3, fruit2, fruit1] 

The simple list fruits will be much easier, less confusing, and better-maintained.

Some examples of use:

All outputs below is the result after running the given code snippet followed by:

for fruit in fruits:
    print fruit

Unsorted list:

Displays:

Name: banana, Color: yellow, Quantity: 32
Name: pear, Color: green, Quantity: 22
Name: apple, Color: red, Quantity: 12

Sorted alphabetically by name:

fruits.sort(key=lambda x: x.name.lower())

Displays:

Name: apple, Color: red, Quantity: 12
Name: banana, Color: yellow, Quantity: 32
Name: pear, Color: green, Quantity: 22

Sorted by quantity:

fruits.sort(key=lambda x: x.quantity)

Displays:

Name: apple, Color: red, Quantity: 12
Name: pear, Color: green, Quantity: 22
Name: banana, Color: yellow, Quantity: 32

Where color == red:

red_fruit = filter(lambda f: f.color == "red", fruits)

Displays:

Name: apple, Color: red, Quantity: 12

simply change the text or value property of controller. if you do not edit selection property cursor goes to first of the new text.

onPress: () {
         _controller.value=TextEditingValue(text: "sample text",selection: TextSelection.fromPosition(TextPosition(offset: sellPriceController.text.length)));                 
             }

or in case you change the .text property:

 onPress: () {
         _controller.text="sample text";
         _controller.selection = TextSelection.fromPosition(TextPosition(offset:_controller.text.length));          
              }

Waterfall methodology is a sequential design process. This means that as each of the eight stages (conception, initiation, analysis, design, construction, testing, implementation, and maintenance) are completed, the developers move on to the next step.

As this process is sequential, once a step has been completed, developers can’t go back to a previous step – not without scratching the whole project and starting from the beginning. There’s no room for change or error, so a project outcome and an extensive plan must be set in the beginning and then followed careful

ACP Agile Certification came about as a “solution” to the disadvantages of the waterfall methodology. Instead of a sequential design process, the Agile methodology follows an incremental approach. Developers start off with a simplistic project design, and then begin to work on small modules. The work on these modules is done in weekly or monthly sprints, and at the end of each sprint, project priorities are evaluated and tests are run. These sprints allow for bugs to be discovered, and customer feedback to be incorporated into the design before the next sprint is run.

The process, with its lack of initial design and steps, is often criticized for its collaborative nature that focuses on principles rather than process.

This error might also occur if you have require.js (requirejs) implemented and you did not wrap some lib that you are using inside

define(['jquery'], function( jQuery ) { ... lib function ... });

NOTE: you do not have to do this if this lib has AMD support. You can quickly check this by opening this lib and just ctrl+f "amd" :)

Give this a try:

CGRect frame = self.textView.frame;
frame.size.height = self.textView.contentSize.height;
self.textView.frame = frame;

Edit- Here's the Swift:

var frame = self.textView.frame
frame.size.height = self.textView.contentSize.height
self.textView.frame = frame

In simple, Normalisation is Reduction of Redundancies.
Examples of Redundancies:
a) white spaces outside of the root/document tags(...<document></document>...)
b) white spaces within start tag (<...>) and end tag (</...>)
c) white spaces between attributes and their values (ie. spaces between key name and =")
d) superfluous namespace declarations
e) line breaks/white spaces in texts of attributes and tags
f) comments etc...

Here's an even better way:

No API calls! And I threw in converting a media_id to a shortcode as an added bonus.

Based on slang's amazing work for figuring out the conversion. Nathan's work converting base10 to base64 in php. And rgbflawed's work converting it back the other way (with a modified alphabet). #teameffort

function mediaid_to_shortcode($mediaid){

    if(strpos($mediaid, '_') !== false){
        $pieces = explode('_', $mediaid);
        $mediaid = $pieces[0];
        $userid = $pieces[1];
    }

    $alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';
    $shortcode = '';
    while($mediaid > 0){
        $remainder = $mediaid % 64;
        $mediaid = ($mediaid-$remainder) / 64;
        $shortcode = $alphabet{$remainder} . $shortcode;
    };

    return $shortcode;

}

function shortcode_to_mediaid($shortcode){

    $alphabet='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_';

    $mediaid = 0;

    foreach(str_split($shortcode) as $letter) {
        $mediaid = ($mediaid*64) + strpos($alphabet, $letter);
    }

    return $mediaid;

}

Beginners needs practical examples. so try the following code.

public class Not_a_Number {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    String message = "0.0/0.0 is NaN.\nsimilarly Math.sqrt(-1) is NaN.";        
    String dottedLine = "------------------------------------------------";     

    Double numerator = -2.0;
    Double denominator = -2.0;      
    while (denominator <= 1) {
        Double x = numerator/denominator;           
        Double y = new Double (x);
        boolean z = y.isNaN();
        System.out.println("y =  " + y);
        System.out.println("z =  " + z);
        if (z == true){
            System.out.println(message);                
        }
        else {
            System.out.println("Hi, everyone"); 
        }
        numerator = numerator + 1;
        denominator = denominator +1;
        System.out.println(dottedLine);         
    } // end of while

} // end of main

} // end of class

bchhun's answer got me on the right track, but I wanted to check for actual space available between the source and the viewport edge. I also wanted to respect the data-placement attribute as a preference with appropriate fallbacks if there wasn't enough space. That way "right" would always go right unless there wasn't enough space for the popover to show on the right side, for example. This was the way I handled it. It works for me, but it feels a bit cumbersome. If anyone has any ideas for a cleaner, more concise solution, I'd be interested to see it.

var options = {
  placement: function (context, source) {
    var $win, $source, winWidth, popoverWidth, popoverHeight, offset, toRight, toLeft, placement, scrollTop;

    $win = $(window);
    $source = $(source);
    placement = $source.attr('data-placement');
    popoverWidth = 400;
    popoverHeight = 110;
    offset = $source.offset();

    // Check for horizontal positioning and try to use it.
    if (placement.match(/^right|left$/)) {
      winWidth = $win.width();
      toRight = winWidth - offset.left - source.offsetWidth;
      toLeft = offset.left;

      if (placement === 'left') {
        if (toLeft > popoverWidth) {
          return 'left';
        }
        else if (toRight > popoverWidth) {
          return 'right';
        }
      }
      else {
        if (toRight > popoverWidth) {
          return 'right';
        }
        else if (toLeft > popoverWidth) {
          return 'left';
        }
      }
    }

    // Handle vertical positioning.
    scrollTop = $win.scrollTop();
    if (placement === 'bottom') {
      if (($win.height() + scrollTop) - (offset.top + source.offsetHeight) > popoverHeight) {
        return 'bottom';
      }
      return 'top';
    }
    else {
      if (offset.top - scrollTop > popoverHeight) {
        return 'top';
      }
      return 'bottom';
    }
  },
  trigger: 'click'
};
$('.infopoint').popover(options);

Actually it's best to use:

IF DB_ID('dms') IS NOT NULL
   --code mine :)
   print 'db exists'

See https://docs.microsoft.com/en-us/sql/t-sql/functions/db-id-transact-sql and note that this does not make sense with the Azure SQL Database.

There is a huge difference.

As most of the answers have already pointed out the theory, I would like to point out an easy example:

int x = 1;
//would print 1 as first statement will x = x and then x will increase
int x = x++;
System.out.println(x);

Now let's see ++x:

int x = 1;
//would print 2 as first statement will increment x and then x will be stored
int x = ++x;
System.out.println(x);

Environment.Exit(exitCode); //exit code 0 is a proper exit and 1 is an error

Do not use Javascript for this!

Modern HTML pages automatically allow a form's submit button to submit the page with the ENTER/RETURN key when any form field control in the web page has focus by the user, autofocus attribute is set on a form field or button, or user tab's into any of the form fields.

So instead of Javascripting this, an easier solution is to add tabindex=0 on your form fields and button inside a form element then autofocus on the first input control. The user can then press "ENTER" to submit the form at any point as they enter data:

<form id="buttonform2" name="buttonform2" action="#" method="get" role="form">
  <label for="username1">Username</label>
  <input type="text" id="username1" name="username" value="" size="20" maxlength="20" title="Username" tabindex="0" autofocus="autofocus" />
  <label for="password1">Password</label>
  <input type="password" id="password1" name="password" size="20" maxlength="20" value="" title="Password" tabindex="0" role="textbox" aria-label="Password" />
  <button id="button2" name="button2" type="submit" value="submit" form="buttonform2" title="Submit" tabindex="0" role="button" aria-label="Submit">Submit</button>
</form>

Since you want to optimize time moving from one page to another in a UIWebView, does it not mean you really are looking to optimize the Javascript used in loading these pages?

To that end, I'd look at a WebKit profiler like that talked about here:

http://www.alertdebugging.com/2009/04/29/building-a-better-javascript-profiler-with-webkit/

Another approach would be to start at a high level, and think how you can design the web pages in question to minimize load times using AJAX style page loading instead of refreshing the whole webview each time.

Use the GeoCoding API

For example, to lookup zip 77379 use a request like this:

https://maps.googleapis.com/maps/api/geocode/json?address=77379&sensor=true&key=YOUR_GOOGLE_PLATFORM_API_KEY

before_filter/before_action: means anything to be executed before any action executes.

Both are same. they are just alias for each other as their behavior is same.

You can set sys.dont_write_bytecode = True in your source, but that would have to be in the first python file loaded. If you execute python somefile.py then you will not get somefile.pyc.

When you install a utility using setup.py and entry_points= you will have set sys.dont_write_bytecode in the startup script. So you cannot rely on the "default" startup script generated by setuptools.

If you start Python with python file as argument yourself you can specify -B:

python -B somefile.py

somefile.pyc would not be generated anyway, but no .pyc files for other files imported too.

If you have some utility myutil and you cannot change that, it will not pass -B to the python interpreter. Just start it by setting the environment variable PYTHONDONTWRITEBYTECODE:

PYTHONDONTWRITEBYTECODE=x myutil

No,but you can do like this

In html file add this section

<div class="arrow">
</div>

In css you can do like this

p div.arrow {
    content: '';
    position: absolute;
    left:100%;
    width: 10px;
    height: 100%;
    background-color: red;
} 

Hope it will help you

Combine JS & CSS :

button{
  /* 1st state */
}

button:hover{
  /* hover state */
}

button:active{
  /* click state */
}

button.active{
  /* after click state */
}


jQuery('button').click(function(){
   jQuery(this).toggleClass('active');
});

Note that a jar file is a Zip file, and any Zip tool (such as 7-Zip) can look inside the jar.

Using MAP you can have 2 arrays in the output: One containing the occurrences & the other one is containing the number of occurrences.

const dataset = [2,2,4,2,6,4,7,8,5,6,7,10,10,10,15];_x000D_
let values = [];_x000D_
let keys = [];_x000D_

var mapWithOccurences = dataset.reduce((a,c) => {_x000D_
  if(a.has(c)) a.set(c,a.get(c)+1);_x000D_
  else a.set(c,1);_x000D_
  return a;_x000D_
}, new Map())_x000D_
.forEach((value, key, map) => {_x000D_
  keys.push(key);_x000D_
  values.push(value);_x000D_
});_x000D_

A quick performance test showing Lutz's solution is the best:

import time

def speed_test(func):
    def wrapper(*args, **kwargs):
        t1 = time.time()
        for x in xrange(5000):
            results = func(*args, **kwargs)
        t2 = time.time()
        print '%s took %0.3f ms' % (func.func_name, (t2-t1)*1000.0)
        return results
    return wrapper

@speed_test
def compare_bitwise(x, y):
    set_x = frozenset(x)
    set_y = frozenset(y)
    return set_x & set_y

@speed_test
def compare_listcomp(x, y):
    return [i for i, j in zip(x, y) if i == j]

@speed_test
def compare_intersect(x, y):
    return frozenset(x).intersection(y)

# Comparing short lists
a = [1, 2, 3, 4, 5]
b = [9, 8, 7, 6, 5]
compare_bitwise(a, b)
compare_listcomp(a, b)
compare_intersect(a, b)

# Comparing longer lists
import random
a = random.sample(xrange(100000), 10000)
b = random.sample(xrange(100000), 10000)
compare_bitwise(a, b)
compare_listcomp(a, b)
compare_intersect(a, b)

These are the results on my machine:

# Short list:
compare_bitwise took 10.145 ms
compare_listcomp took 11.157 ms
compare_intersect took 7.461 ms

# Long list:
compare_bitwise took 11203.709 ms
compare_listcomp took 17361.736 ms
compare_intersect took 6833.768 ms

Obviously, any artificial performance test should be taken with a grain of salt, but since the set().intersection() answer is at least as fast as the other solutions, and also the most readable, it should be the standard solution for this common problem.

If You're using php5.6 and Ubuntu 18.04 Then run these two commands in your terminal your errors will be solved definitely.

sudo apt-get install php5.6-gd

then restart your apache server by this command.

 sudo service apache2 restart

Here is the list of commands you have to run while the emulator is running, I test this solution for an avd on Android 2.2 :

adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system  
adb push su /system/xbin/su  
adb shell chmod 06755 /system  
adb shell chmod 06755 /system/xbin/su

It assumes that the su binary is located in the working directory. You can find su and superuser here : http://forum.xda-developers.com/showthread.php?t=682828. You need to run these commands each time you launch the emulator. You can write a script that launch the emulator and root it.

This is common issue with floating points.

Use toFixed in combination with parseFloat.

Here is example in JavaScript:

function roundNumber(number, decimals) {
    var newnumber = new Number(number+'').toFixed(parseInt(decimals));
    return parseFloat(newnumber); 
}

0.1 + 0.2;                    //=> 0.30000000000000004
roundNumber( 0.1 + 0.2, 12 ); //=> 0.3

The way I use is:

git submodule update --init --recursive
git submodule foreach --recursive git fetch
git submodule foreach git merge origin master

• float stores floating-point values, that is, values that have potential decimal places
• int only stores integral values, that is, whole numbers

So while both are 32 bits wide, their use (and representation) is quite different. You cannot store 3.141 in an integer, but you can in a float.

Dissecting them both a little further:

In an integer, all bits are used to store the number value. This is (in Java and many computers too) done in the so-called two's complement. This basically means that you can represent the values of −2³¹ to 2³¹ − 1.

In a float, those 32 bits are divided between three distinct parts: The sign bit, the exponent and the mantissa. They are laid out as follows:

S EEEEEEEE MMMMMMMMMMMMMMMMMMMMMMM

There is a single bit that determines whether the number is negative or non-negative (zero is neither positive nor negative, but has the sign bit set to zero). Then there are eight bits of an exponent and 23 bits of mantissa. To get a useful number from that, (roughly) the following calculation is performed:

M × 2^E

(There is more to it, but this should suffice for the purpose of this discussion)

The mantissa is in essence not much more than a 24-bit integer number. This gets multiplied by 2 to the power of the exponent part, which, roughly, is a number between −128 and 127.

Therefore you can accurately represent all numbers that would fit in a 24-bit integer but the numeric range is also much greater as larger exponents allow for larger values. For example, the maximum value for a float is around 3.4 × 10³⁸ whereas int only allows values up to 2.1 × 10⁹.

But that also means, since 32 bits only have 4.2 × 10⁹ different states (which are all used to represent the values int can store), that at the larger end of float's numeric range the numbers are spaced wider apart (since there cannot be more unique float numbers than there are unique int numbers). You cannot represent some numbers exactly, then. For example, the number 2 × 10¹² has a representation in float of 1,999,999,991,808. That might be close to 2,000,000,000,000 but it's not exact. Likewise, adding 1 to that number does not change it because 1 is too small to make a difference in the larger scales float is using there.

Similarly, you can also represent very small numbers (between 0 and 1) in a float but regardless of whether the numbers are very large or very small, float only has a precision of around 6 or 7 decimal digits. If you have large numbers those digits are at the start of the number (e.g. 4.51534 × 10³⁵, which is nothing more than 451534 follows by 30 zeroes – and float cannot tell anything useful about whether those 30 digits are actually zeroes or something else), for very small numbers (e.g. 3.14159 × 10⁻²⁷) they are at the far end of the number, way beyond the starting digits of 0.0000...

Perhaps not what the OP was after, but for those searching the URL to simply access a readable object on S3 is more like:

https://<region>.amazonaws.com/<bucket-name>/<key>

Where <region> is something like s3-ap-southeast-2.

Click on the item in the S3 GUI to get the link for your bucket.

Does this help?

//get the full location of the assembly with DaoTests in it
string fullPath = System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location;

//get the folder that's in
string theDirectory = Path.GetDirectoryName( fullPath );

Another approach with lapply and a dplyr statement. We can apply an arbitrary number of whatever summary functions to the same statement:

lapply(c(first, last), 
       function(x) df %>% group_by(id) %>% summarize_all(funs(x))) %>% 
bind_rows()

You could for example be interested in rows with the max stopSequence value as well and do:

lapply(c(first, last, max("stopSequence")), 
       function(x) df %>% group_by(id) %>% summarize_all(funs(x))) %>%
bind_rows()

The best approach to this problem is first making the database column UNIQUE

ALTER TABLE table_name ADD UNIQUE KEY

THEN INSERT IGNORE INTO table_name ,the value won't be inserted if it results in a duplicate key/already exists in the table.

I only added one plus(+) before string and that was solution!

+"052254" //52254

Hope it helps ;)

A common PyTorch convention is to save models using either a .pt or .pth file extension.

Save/Load Entire Model Save:

path = "username/directory/lstmmodelgpu.pth"
torch.save(trainer, path)

Load:

Model class must be defined somewhere

model = torch.load(PATH)
model.eval()

As of ISO7 at least you can easily do this with NSJSONSerialization.

I typically see a 30% speed improvement for compute-intensive code on x86-64 compared to x86. This is most likely due to the fact that we have 16 x 64 bit general purpose registers and 16 x SSE registers instead of 8 x 32 bit general purpose registers and 8 x SSE registers. This is with the Intel ICC compiler (11.1) on an x86-64 Linux - results with other compilers (e.g. gcc), or with other operating systems (e.g. Windows), may be different of course.

Checkout CefSharp .Net bindings, a project I started a while back that thankfully got picked up by the community and turned into something wonderful.

The project wraps the Chromium Embedded Framework and has been used in a number of major projects including Rdio's Windows client, Facebook Messenger for Windows and Github for Windows.

It features browser controls for WPF and Winforms and has tons of features and extension points. Being based on Chromium it's blisteringly fast too.

Grab it from NuGet: Install-Package CefSharp.Wpf or Install-Package CefSharp.WinForms

Emulation is the process of mimicking the outwardly observable behavior to match an existing target. The internal state of the emulation mechanism does not have to accurately reflect the internal state of the target which it is emulating.

Simulation, on the other hand, involves modeling the underlying state of the target. The end result of a good simulation is that the simulation model will emulate the target which it is simulating.

Ideally, you should be able to look into the simulation and observe properties that you would also see if you looked into the original target. In practice, there may some shortcuts to the simulation for performance reasons -- that is, some internal aspects of the simulation may actually be an emulation.

MAME is an arcade game emulator; Hyperterm is a (not very good) terminal emulator. There's no need to model the arcade machine or a terminal in detail to get the desired emulated behavior.

Flight Simulator is a simulator; SPICE is an electronics simulator. They model as much as possible every detail of the target to represent what the target does in reality.

EDIT: Other responses have pointed out that the goal of an emulation is to able to substitute for the object it is emulating. That's an important point. A simulation's focus is more on the modelling of the internal state of the target -- and the simulation does not necessarily lead to emulation. In particular, a simulation may run far slower than real time. SPICE, for example, cannot substitue for an actual electronics circuit (even if assuming there was some kind of magical device that perfectly interfaces electrical circuits to a SPICE simulation.) A simulation Simulation does not always lead to emulation --

You can use a CompletionService to receive the futures as soon as they are ready and if one of them throws an exception cancel the processing. Something like this:

Executor executor = Executors.newFixedThreadPool(4);
CompletionService<SomeResult> completionService = 
       new ExecutorCompletionService<SomeResult>(executor);

//4 tasks
for(int i = 0; i < 4; i++) {
   completionService.submit(new Callable<SomeResult>() {
       public SomeResult call() {
           ...
           return result;
       }
   });
}

int received = 0;
boolean errors = false;

while(received < 4 && !errors) {
      Future<SomeResult> resultFuture = completionService.take(); //blocks if none available
      try {
         SomeResult result = resultFuture.get();
         received ++;
         ... // do something with the result
      }
      catch(Exception e) {
             //log
         errors = true;
      }
}

I think you can further improve to cancel any still executing tasks if one of them throws an error.

If you're using V4.1, and according to their docs, don't assign .table-responsive directly to the table. The table should be .table and if you want it to be horizontally scrollable (responsive) add it inside a .table-responsive container (a <div>, for instance).

Responsive tables allow tables to be scrolled horizontally with ease. Make any table responsive across all viewports by wrapping a .table with .table-responsive.

<div class="table-responsive">
  <table class="table">
  ...
  </table>
</div>

doing that, no extra css is needed.

In the OP's code, .table-responsive can be used alongside with the .col-md-12 on the outside .

Here's another way

Sub testborder()

    Dim rRng As Range

    Set rRng = Sheet1.Range("B2:D5")

    'Clear existing
    rRng.Borders.LineStyle = xlNone

    'Apply new borders
    rRng.BorderAround xlContinuous
    rRng.Borders(xlInsideHorizontal).LineStyle = xlContinuous
    rRng.Borders(xlInsideVertical).LineStyle = xlContinuous

End Sub

To list untracked files try:

git ls-files --others --exclude-standard

If you need to pipe the output to xargs, it is wise to mind white spaces using git ls-files -z and xargs -0:

git ls-files -z -o --exclude-standard | xargs -0 git add

Nice alias for adding untracked files:

au = !git add $(git ls-files -o --exclude-standard)

Edit: For reference: git-ls-files

public static <E> E[] appendToArray(E[] array, E item) { ...

Note the <E>.

Static generic methods need their own generic declaration (public static <E>) separate from the class's generic declaration (public class ArrayUtils<E>).

If the compiler complains about a type ambiguity in invoking a static generic method (again not likely in your case, but, generally speaking, just in case), here's how to explicitly invoke a static generic method using a specific type (_class_.<_generictypeparams_>_methodname_):

String[] newStrings = ArrayUtils.<String>appendToArray(strings, "another string");

This would only happen if the compiler can't determine the generic type because, e.g. the generic type isn't related to the method arguments.

Use x=as.name("string"). You can use then use x to refer to the variable with name string.

I don't know, if it answers your question correctly.

So as to have another possibility¹ to find the files that are executable by the current user:

find . -type f -exec test -x {} \; -print

(the test command here is the one found in PATH, very likely /usr/bin/test, not the builtin).

¹ Only use this if the -executable flag of find is not available! this is subtly different from the -perm +111 solution.

I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.

If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.

The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.

I got similar error sometime back. I had copied the eclipse setup from another laptop to mine. The issue with my setup was that path of the "--launcher.library" in the eclipse.ini file. The path in --launcher.library was that of the old machine and hence I was getting the error

I changed the path of "--launcher.library" in eclipse.ini to the path of eclipse on my laptop and the issue got resolved. I hope this is helpful to someone is getting this error.

This is one of the way to add google site search to websites:

Another alternative might be to use Flask-APScheduler which plays nicely with Flask, e.g.:

• Loads scheduler configuration from Flask configuration,
• Loads job definitions from Flask configuration

THE “PARENT” SELECTOR

Right now, there is no option to select the parent of an element in CSS (not even CSS3). But with CSS4, the most important news in the current W3C draft is the support for the parent selector.

$ul li:hover{
    background: #fff;
}

Using the above, when hovering an list element, the whole unordered list will be highlighted by adding a white background to it.

Official documentation: https://www.w3.org/TR/2011/WD-selectors4-20110929/#overview (last row).

The best bet is to use the numpy library.

For folks who find this on Google, I needed to search the first n lines of multiple files, but to only print the matching filenames. I used

 gawk 'FNR>10 {nextfile} /pattern/ { print FILENAME ; nextfile }' filenames

The FNR..nextfile stops processing a file once 10 lines have been seen. The //..{} prints the filename and moves on whenever the first match in a given file shows up. To quote the filenames for the benefit of other programs, use

 gawk 'FNR>10 {nextfile} /pattern/ { print "\"" FILENAME "\"" ; nextfile }' filenames

Or there's the obvious answer: use the End key to go to the end of the line.

Your code is correct. Kindly mark small correction.

#rightcolumn {
     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;

Extending on Tadeck's Django answer above, the use of 'class Meta:' in Django is just normal Python too.

The internal class is a convenient namespace for shared data among the class instances (hence the name Meta for 'metadata' but you can call it anything you like). While in Django it's generally read-only configuration stuff, there is nothing to stop you changing it:

In [1]: class Foo(object):
   ...:     class Meta:
   ...:         metaVal = 1
   ...:         
In [2]: f1 = Foo()
In [3]: f2 = Foo()
In [4]: f1.Meta.metaVal
Out[4]: 1
In [5]: f2.Meta.metaVal = 2
In [6]: f1.Meta.metaVal
Out[6]: 2
In [7]: Foo.Meta.metaVal
Out[7]: 2

You can explore it in Django directly too e.g:

In [1]: from django.contrib.auth.models import User
In [2]: User.Meta
Out[2]: django.contrib.auth.models.Meta
In [3]: User.Meta.__dict__
Out[3]: 
{'__doc__': None,
 '__module__': 'django.contrib.auth.models',
 'abstract': False,
 'verbose_name': <django.utils.functional.__proxy__ at 0x26a6610>,
 'verbose_name_plural': <django.utils.functional.__proxy__ at 0x26a6650>}

However, in Django you are more likely to want to explore the _meta attribute which is an Options object created by the model metaclass when a model is created. That is where you'll find all of the Django class 'meta' information. In Django, Meta is just used to pass information into the process of creating the _meta Options object.

I assume that you want to read input from the console. If so, use Read-Host.

Your css is almost correct. You are just missing display: block; in image css. Also one typo in your id. It should be <div id="ImageContainer">

img.Image { max-width: 100%; display: block; }_x000D_
div#ImageContainer { width: 600px; }

<div id="ImageContainer">_x000D_
    <img src="http://placehold.it/1000x600" class="Image">_x000D_
</div>

You need not to worry

Just enable Jetifier in your projet.

• Update Android Studio to 3.2.0 or newer.

• Open gradle.properties and add below two lines.

  android.enableJetifier=true
  android.useAndroidX=true
  

It will convert all support libraries of your dependency to AndroidX at run time (you may have compile time errors, but app will run).

1) Open a Developer Command Prompt for VS 2017 (or whatever version you have on your machine)(It should be located under: Start menu --> All programs --> Visual Studio 2017 (or whatever version you have on your machine) --> Visual Studio Tools --> Developer Command Prompt for VS 2017.

2) Enter the following command:

dumpbin /EXPORTS my_lib_name.lib

Batch files are processed row by row and terminate whenever you call an executable directly.
- To make the batch file wait for the process to terminate and continue, put call in front of it.
- To make the batch file continue without waiting, put start "" in front of it.

I recommend using this single line script to accomplish your goal:

@call cscript "%~dp0necdaily.vbs"

(because this is a single line, you can use @ instead of @echo off)

If you believe your script can only be called from the SysWOW64 versions of cmd.exe, you might try:

@%WINDIR%\SysWOW64\cmd.exe /c call cscript "%~dp0necdaily.vbs"

If you need the window to remain, you can replace /c with /k

we should use name value pair binding values into dropdown.see the code for more details

function myCtrl($scope) {_x000D_
     $scope.statusTaskList = [_x000D_
        { name: 'Open', value: '1' },_x000D_
        { name: 'In Progress', value: '2' },_x000D_
        { name: 'Complete', value: '3' },_x000D_
        { name: 'Deleted', value: '4' },_x000D_
    ];_x000D_
    $scope.atcStatusTasks = $scope.statusTaskList[0]; // 0 -> Open _x000D_
}

<select ng-model="atcStatusTasks" ng-options="s.name for s in statusTaskList"></select>

After chaning to unlimited, database came back to life.

It depends on the likelihood of a semicolon ending up near your &, causing it to display something quite different.

For example, when dealing with input from users (say, if you include the user-provided subject of a forum post in your title tags), you never know where they might be putting random semicolons, and it might randomly display strange entities. So always escape in that situation.

For your own static html, sure, you could skip it, but it's so trivial to include proper escaping, that there's no good reason to avoid it.

try this:

public int getRandomNumber(int min, int max) {
    return (int) Math.floor(Math.random() * (max - min + 1)) + min;
}

If you are using reactiveFormModule and have formGroup defined like this:

public exampleForm = new FormGroup({
        name: new FormControl('Test name', [Validators.required, Validators.minLength(3)]),
        email: new FormControl('[email protected]', [Validators.required, Validators.maxLength(50)]),
        age: new FormControl(45, [Validators.min(18), Validators.max(65)])
});

than you are able to add a new validator (and keep old ones) to FormControl with this approach:

this.exampleForm.get('age').setValidators([
        Validators.pattern('^[0-9]*$'),
        this.exampleForm.get('age').validator
]);
this.exampleForm.get('email').setValidators([
        Validators.email,
        this.exampleForm.get('email').validator
]);

FormControl.validator returns a compose validator containing all previously defined validators.

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

You can use the following little trick:

set word=table
set str="jump over the chair"
call set str=%%str:chair=%word%%%
echo %str%

The call there causes another layer of variable expansion, making it necessary to quote the original % signs but it all works out in the end.

it should work using - (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated using it this way:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[yourTableView scrollToRowAtIndexPath:indexPath 
                     atScrollPosition:UITableViewScrollPositionTop 
                             animated:YES];

atScrollPosition could take any of these values:

typedef enum {
UITableViewScrollPositionNone,
UITableViewScrollPositionTop,
UITableViewScrollPositionMiddle,
UITableViewScrollPositionBottom
} UITableViewScrollPosition;

I hope this helps you

So when sending the message to telegram you use:

$token = <Enter Your Token Here>
$url = "https://api.telegram.org/bot".$token;

$chat_id = <The Chat Id Goes Here>;
$test = <Message goes Here>;

//sending Message normally without styling
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text");

If our message has html tags in it we add "parse_mode" so that our url becomes:

$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text&parse_mode=html")

parse mode can be "HTML" or "markdown"

Piping is your friend...

Use grep -A1 to show the next line after a match, then pipe the result to tail and only grab 1 line,

cat logs/info.log | grep "term" -A1 | tail -n 1

UPDATE(NEW SOLUTION)

This update is the best solution of iOS 7 navigation bar problem.You can set navigation bar color example: FakeNavBar.backgroundColor = [UIColor redColor];

Note : If you use default Navigation Controller please use old solution.

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    if(NSFoundationVersionNumber >= NSFoundationVersionNumber_iOS_7_0)
    {
        UIView *FakeNavBar = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];
        FakeNavBar.backgroundColor = [UIColor whiteColor];

        float navBarHeight = 20.0;
        for (UIView *subView in self.window.subviews) {

            if ([subView isKindOfClass:[UIScrollView class]]) {
                subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y + navBarHeight, subView.frame.size.width, subView.frame.size.height - navBarHeight);
            } else {
                subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y + navBarHeight, subView.frame.size.width, subView.frame.size.height);
            }
        }
        [self.window addSubview:FakeNavBar];
    }

    return YES;

}

OLD SOLUTION - IF you use previous code please ignore following Code and Image

This is old version of iOS 7 navigation bar solution.

I solved the problem with the following code. This is for adding a status bar. didFinishLaunchingWithOptions

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    UIView *addStatusBar = [[UIView alloc] init];
    addStatusBar.frame = CGRectMake(0, 0, 320, 20);
    addStatusBar.backgroundColor = [UIColor colorWithRed:0.973 green:0.973 blue:0.973 alpha:1]; //change this to match your navigation bar
    [self.window.rootViewController.view addSubview:addStatusBar];
}

And for Interface Builder this is for when you open with iOS 6; it is starting at 0 pixels.

DisplayMetrics displayMetrics = new DisplayMetrics();

getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);

int width_px = Resources.getSystem().getDisplayMetrics().widthPixels;

int height_px =Resources.getSystem().getDisplayMetrics().heightPixels;

int pixeldpi = Resources.getSystem().getDisplayMetrics().densityDpi;


int width_dp = (width_px/pixeldpi)*160;
int height_dp = (height_px/pixeldpi)*160;

This worked for me.

string stringSeparators = "\r\n";
string text = sr.ReadToEnd();
string lines = text.Replace(stringSeparators, "");
lines = lines.Replace("\\r\\n", "\r\n");
Console.WriteLine(lines);

The first replace replaces the \r\n from the text file's new lines, and the second replaces the actual \r\n text that is converted to \\r\\n when the files is read. (When the file is read \ becomes \\).

#0000ffff - that is the code that you need for transparent. I just did it and it worked.

Replace bigint(20) not null auto_increment by bigserial not null and datetime by timestamp

A character class in regular expressions, denoted by the [...] syntax, specifies the rules to match a single character in the input. As such, everything you write between the brackets specify how to match a single character.

Your pattern, [01-12] is thus broken down as follows:

• 0 - match the single digit 0
• or, 1-1, match a single digit in the range of 1 through 1
• or, 2, match a single digit 2

So basically all you're matching is 0, 1 or 2.

In order to do the matching you want, matching two digits, ranging from 01-12 as numbers, you need to think about how they will look as text.

You have:

• 01-09 (ie. first digit is 0, second digit is 1-9)
• 10-12 (ie. first digit is 1, second digit is 0-2)

You will then have to write a regular expression for that, which can look like this:

  +-- a 0 followed by 1-9
  |
  |      +-- a 1 followed by 0-2
  |      |
<-+--> <-+-->
0[1-9]|1[0-2]
      ^
      |
      +-- vertical bar, this roughly means "OR" in this context

Note that trying to combine them in order to get a shorter expression will fail, by giving false positive matches for invalid input.

For instance, the pattern [0-1][0-9] would basically match the numbers 00-19, which is a bit more than what you want.

I tried finding a definite source for more information about character classes, but for now all I can give you is this Google Query for Regex Character Classes. Hopefully you'll be able to find some more information there to help you.

I am running Anaconda version 4.3.22 and a python3.6.1 environment, and had this problem. Here's the history and the fix:

pip uninstall opencv-python # -- the original step. failed.

ImportError: DLL load failed: The specified module could not be found.

I did this into my python3.6 environment and got this error.

python -m pip install opencv-python # same package as above.
conda install -c conda-forge opencv # separate install parallel to opencv
pip-install opencv-contrib-python # suggested by another user here. doesn't resolve it.

Next, I tried downloading python3.6 and putting the python3.dll in the folder and in various folders. nothing changed.

finally, this fixed it:

pip uninstall opencv-python

(the other conda-forge version is still installed) This left only the conda version, and that works in 3.6.

>>>import cv2

working!

You can also do this with linq if you'd like

var names = new List<string>() { "John", "Anna", "Monica" };
var joinedNames = names.Aggregate((a, b) => a + ", " + b);

Although I prefer the non-linq syntax in Quartermeister's answer and I think Aggregate might perform slower (probably more string concatenation operations).

The man page for test (man test) provides all available operators you can use as boolean operators in bash. Use those flags in the beginning of your script (or functions) for input validation just like you would in any other programming language. For example:

if [ -z $1 ] ; then
  echo "First parameter needed!" && exit 1;
fi

if [ -z $2 ] ; then
  echo "Second parameter needed!" && exit 2;

1. change the table view's style - make it grouped for not sticky & make it plain for sticky section headers - do not forget: you can do it from storyboard without writing code. (click on your table view and change it is style from the right Side/ component menu)

2. if you have extra components such as custom views or etc. please check the table view's margins to create appropriate design. (such as height of header for sections & height of cell at index path, sections)

Use a credential store.

For Git 2.11+ on OS X and Linux, use Git's built in credential store:

git config --global credential.helper libsecret

For msysgit 1.7.9+ on Windows:

git config --global credential.helper wincred

For Git 1.7.9+ on OS X use:

git config --global credential.helper osxkeychain

You can use the addMethod()

e.g

$.validator.addMethod('postalCode', function (value) { 
    return /^((\d{5}-\d{4})|(\d{5})|([A-Z]\d[A-Z]\s\d[A-Z]\d))$/.test(value); 
}, 'Please enter a valid US or Canadian postal code.');

You may do this as of C# 9.0:

switch(myvar)
{
    case 2 or 5:
        // ...
        break;

    case 7 or 12:
        // ...
        break;
    // ...
}

Don't update the primary key. It could cause a lot of problems for you keeping your data intact, if you have any other tables referencing it.

Ideally, if you want a unique field that is updateable, create a new field.

Try below code

I will recommend to use error handler while using vlookup because error might occur when the lookup_value is not found.

Private Sub ComboBox1_Change()


    On Error Resume Next
    Ret = Application.WorksheetFunction.VLookup(Me.ComboBox1.Value, Worksheets("Sheet3").Range("Names"), 2, False)
    On Error GoTo 0

    If Ret <> "" Then MsgBox Ret


End Sub

OR

 On Error Resume Next

    Result = Application.VLookup(Me.ComboBox1.Value, Worksheets("Sheet3").Range("Names"), 2, False)

    If Result = "Error 2042" Then
        'nothing found
    ElseIf cell <> Result Then
        MsgBox cell.Value
    End If

    On Error GoTo 0

Although MSDN says that "s" and "o" formats reflect the standard, they seem to be able to parse only a limited subset of it. Especially it is a problem if the string contains time zone specification. (Neither it does for basic ISO8601 formats, or reduced precision formats - however this is not exactly your case.) That is why I make use of custom format strings when it comes to parsing ISO8601. Currently my preferred snippet is:

static readonly string[] formats = { 
    // Basic formats
    "yyyyMMddTHHmmsszzz",
    "yyyyMMddTHHmmsszz",
    "yyyyMMddTHHmmssZ",
    // Extended formats
    "yyyy-MM-ddTHH:mm:sszzz",
    "yyyy-MM-ddTHH:mm:sszz",
    "yyyy-MM-ddTHH:mm:ssZ",
    // All of the above with reduced accuracy
    "yyyyMMddTHHmmzzz",
    "yyyyMMddTHHmmzz",
    "yyyyMMddTHHmmZ",
    "yyyy-MM-ddTHH:mmzzz",
    "yyyy-MM-ddTHH:mmzz",
    "yyyy-MM-ddTHH:mmZ",
    // Accuracy reduced to hours
    "yyyyMMddTHHzzz",
    "yyyyMMddTHHzz",
    "yyyyMMddTHHZ",
    "yyyy-MM-ddTHHzzz",
    "yyyy-MM-ddTHHzz",
    "yyyy-MM-ddTHHZ"
    };

public static DateTime ParseISO8601String ( string str )
{
    return DateTime.ParseExact ( str, formats, 
        CultureInfo.InvariantCulture, DateTimeStyles.None );
}

If you don't mind parsing TZ-less strings (I do), you can add an "s" line to greatly extend the number of covered format alterations.

When a clearfix is used in a parent container, it automatically wraps around all the child elements.

It is usually used after floating elements to clear the float layout.

When float layout is used, it will horizontally align the child elements. Clearfix clears this behaviour.

Example - Bootstrap Panels

In bootstrap, when the class panel is used, there are 3 child types: panel-header, panel-body, panel-footer. All of which have display:block layout but panel-body has a clearfix pre-applied. panel-body is a main container type whereas panel-header & panel-footer isn't intended to be a container, it is just intended to hold some basic text.

If floating elements are added, the parent container does not get wrapped around those elements because the height of floating elements is not inherited by the parent container.

So for panel-header & panel-footer, clearfix is needed to clear the float layout of elements: Clearfix class gives a visual appearance that the height of the parent container has been increased to accommodate all of its child elements.

 <div class="container">
    <div class="panel panel-default">
        <div class="panel-footer">
            <div class="col-xs-6">
                <input type="button" class="btn btn-primary"   value="Button1">
                <input type="button" class="btn btn-primary"   value="Button2">
                <input type="button" class="btn btn-primary"   value="Button3">
            </div>
        </div>
    </div>

    <div class="panel panel-default">
        <div class="panel-footer">
            <div class="col-xs-6">
                <input type="button" class="btn btn-primary"   value="Button1">
                <input type="button" class="btn btn-primary"   value="Button2">
                <input type="button" class="btn btn-primary"   value="Button3">
            </div>
            <div class="clearfix"/>
        </div>
    </div>
</div>

The comma got eaten by the quotes!

This part:

("username," visitorName);

Should be this:

("username", visitorName);

Aside: For pasting code into the console, you can paste them in one line at a time to help you pinpoint where things went wrong ;-)

You could try doing it through R:

For Stata <= 15 you can use the haven package to read the dataset and then you simply write it to external CSV file:

library(haven)
yourData = read_dta("path/to/file")
write.csv(yourData, file = "yourStataFile.csv")

Alternatively, visit the link pointed by huntaub in a comment below.

For Stata <= 12 datasets foreign package can also be used

library(foreign)
yourData <- read.dta("yourStataFile.dta")

There are a lot of detailed answers here, but I thought I should add this to address accessibility since there are implications.

display: none; and visibility: hidden; may not be read by all screen reader software. Keep in mind what visually-impaired users will experience.

The question also asks about synonyms. text-indent: -9999px; is one other that is roughly equivalent. The important difference with text-indent is that it will often be read by screen readers. It can be a bit of a bad experience as users can still tab to the link.

For accessibility, what I see used today is a combination of styles to hide an element while being visible to screen readers.

{
  clip: rect(1px, 1px, 1px, 1px);
  clip-path: inset(50%);
  height: 1px;
  width: 1px;
  margin: -1px;
  overflow: hidden;
  padding: 0;
  position: absolute;
}

A great practice is to create a "Skip to content" link to the anchor of the main body of content. Visually-impaired users probably don't want to listen to your full navigation tree on every single page. Make the link visually hidden. Users can just hit tab to access the link.

For more on accessibility and hidden content, see:

It is not good practice to hard code strings into your layout files. You should add them to a string resource file and then reference them from your layout.

This allows you to update every occurrence of the word "Yellow" in all layouts at the same time by just editing your strings.xml file.

It is also extremely useful for supporting multiple languages as a separate strings.xml file can be used for each supported language.

example: XML file saved at res/values/strings.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="yellow">Yellow</string>
</resources>

This layout XML applies a string to a View:

<TextView android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:text="@string/yellow" />

Similarly colors should be stored in colors.xml and then referenced by using @color/color_name

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="Black">#000000</color>
</resources>

What works for me is to set the following line in your CMakeLists.txt:

set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

Setting this command activates the C++11 features for the compiler and after executing the cmake .. command, you should be able to use range based for loops in your code and compile it without any errors.

This should work:

if(gender.equals("Male")){
 salutation ="Mr.";
}
else if(gender.equals("Female")){
 salutation ="Ms.";
}

Remember, not to use ; after if statement.

Why not have the original drop down on the page be a 2 digit value only? Credit cards only cover a small span when looking at the year especially if the CC vendor only takes in 2 digits already.

JavaScript runs in the context of the current HTML document, so it won't be able to determine anything about a current user unless it's in the current page or you do AJAX calls to a server-side script to get more information.

JavaScript will not be able to determine your Windows user name.

<?php 
  $ConvertDateBack = Zend_Controller_Action_HelperBroker::getStaticHelper('ConvertDate');
  $disabledDaysRange = array();
  foreach($this->reservedDates as $dates) {
    $date = $ConvertDateBack->ConvertDateBack($dates->reservation_date);
    $disabledDaysRange[] = $date;
  }
  $disDays = size($disabledDaysRange);
?>
<script>
var disabledDaysRange = {};
var disDays = '<?=$disDays;?>';
for(i=0;i<disDays;i++) {
  array.push(disabledDaysRange,'<?=$disabledDaysRange[' + i + '];?>');
}

The first is the most concise, I would go with that. The first two are the same, but the first is just that little bit shorter, so you'll save on bytes. The third is plain wrong, because that condition will always evaluate true because the object will never be null or falsy for that matter.

often in books you will find the explanation of casting from int to byte as being performed by modulus division. this is not strictly correct as shown below what actually happens is the 24 most significant bits from the binary value of the int number are discarded leaving confusion if the remaining leftmost bit is set which designates the number as negative

public class castingsample{

public static void main(String args[]){

    int i;
    byte y;
    i = 1024;
    for(i = 1024; i > 0; i-- ){

      y = (byte)i;
      System.out.print(i + " mod 128 = " + i%128 + " also ");
      System.out.println(i + " cast to byte " + " = " + y);

    }

}

}
