From within a view that has Class1 as it's strongly typed view model:

ModelMetadata.FromLambdaExpression<Class1, string>(x => x.Name, ViewData).DisplayName;

There is a lot of confusion here, especially if you read outdated sources.

The basic one is Activity, which can show Fragments. You can use this combination if you're on Android version > 4.

However, there is also a support library which encompasses the other classes you mentioned: FragmentActivity, ActionBarActivity and AppCompat. Originally they were used to support fragments on Android versions < 4, but actually they're also used to backport functionality from newer versions of Android (material design for example).

The latest one is AppCompat, the other 2 are older. The strategy I use is to always use AppCompat, so that the app will be ready in case of backports from future versions of Android.

Everyone who answered before me is correct. You use it kind of as an alias shortcut name for a table when you have long queries or queries that have joins. Here's a couple examples.

Example 1

SELECT P.ProductName,
       P.ProductGroup,
       P.ProductRetailPrice
FROM   Products AS P

Example 2

SELECT P.ProductName,
       P.ProductRetailPrice,
       O.Quantity
FROM   Products AS P
LEFT OUTER JOIN Orders AS O ON O.ProductID = P.ProductID
WHERE  O.OrderID = 123456

Example 3 It's a good practice to use the AS keyword, and very recommended, but it is possible to perform the same query without one (and I do often).

SELECT P.ProductName,
       P.ProductRetailPrice,
       O.Quantity
FROM   Products P
LEFT OUTER JOIN Orders O ON O.ProductID = P.ProductID
WHERE  O.OrderID = 123456

As you can tell, I left out the AS keyword in the last example. And it can be used as an alias.

Example 4

SELECT P.ProductName AS "Product",
       P.ProductRetailPrice AS "Retail Price",
       O.Quantity AS "Quantity Ordered"
FROM   Products P
LEFT OUTER JOIN Orders O ON O.ProductID = P.ProductID
WHERE  O.OrderID = 123456

Output of Example 4

Product             Retail Price     Quantity Ordered
Blue Raspberry Gum  $10 pk/$50 Case  2 Cases
Twizzler            $5 pk/$25 Case   10 Cases

Applying a selector from the .nav-tabs seems to be working: See this demo.

$(document).ready(function(){
    activaTab('aaa');
});

function activaTab(tab){
    $('.nav-tabs a[href="#' + tab + '"]').tab('show');
};

I would prefer @codedme's answer, since if you know which tab you want prior to page load, you should probably change the page html and not use JS for this particular task.

I tweaked the demo for his answer, as well.

(If this is not working for you, please specify your setting - browser, environment, etc.)

As of PowerShell 5.1 there cmdlet New-LocalUser which could create local user account.

Example of usage:

Create a user account

New-LocalUser -Name "User02" -Description "Description of this account." -NoPassword

or Create a user account that has a password

$Password = Read-Host -AsSecureString
New-LocalUser "User03" -Password $Password -FullName "Third User" -Description "Description of this account."

or Create a user account that is connected to a Microsoft account

New-LocalUser -Name "MicrosoftAccount\usr [email protected]" -Description "Description of this account." 

('my string'.match(/\s/g) || []).length;

Just to add my results, also using Matplotlib.

.eps made all my text bold and removed transparency. .svg gave me high-resolution pictures that actually looked like my graph.

import matplotlib.pyplot as plt
fig, ax = plt.subplots()
# Do the plot code
fig.savefig('myimage.svg', format='svg', dpi=1200)

I used 1200 dpi because a lot of scientific journals require images in 1200 / 600 / 300 dpi, depending on what the image is of. Convert to desired dpi and format in GIMP or Inkscape.

Obviously the dpi doesn't matter since .svg are vector graphics and have "infinite resolution".

make sure you're using the newest jquery, and problem solved

I met this problem with this code:

<script src="/scripts/plugins/jquery/jquery-1.6.2.min.js"> </script>
<script src="/scripts/plugins/bootstrap/js/bootstrap.js"></script>

After change it to this:

<script src="/scripts/plugins/jquery/jquery-1.7.2.min.js"> </script>
<script src="/scripts/plugins/bootstrap/js/bootstrap.js"></script>

It works fine

Annotations come from the support's library which are packaged in android.support.annotation.

As another option you can use @NonNull annotation which denotes that a parameter, field or method return value can never be null.
It is imported from import android.support.annotation.NonNull;

This code should do it in SQL 2005, but a few caveats:

1. It is RIDICULOUSLY slow. I tested it on a small database that I have with only a handful of tables and it took many minutes to complete. If your database is so big that you can't understand it then this will probably be unusable anyway.

2. I wrote this off the cuff. I didn't put in any error handling and there might be some other sloppiness especially since I don't use cursors often. For example, I think there's a way to refresh the columns cursor instead of closing/deallocating/recreating it every time.

If you can't understand the database or don't know where stuff is coming from, then you should probably find someone who does. Even if you can find where the data is, it might be duplicated somewhere or there might be other aspects of the database that you don't understand. If no one in your company understands the database then you're in a pretty big mess.

First, make an ifstream:

#include <fstream>
std::ifstream infile("thefile.txt");

The two standard methods are:

1. Assume that every line consists of two numbers and read token by token:

   int a, b;
   while (infile >> a >> b)
   {
       // process pair (a,b)
   }
   

2. Line-based parsing, using string streams:

   #include <sstream>
   #include <string>
   
   std::string line;
   while (std::getline(infile, line))
   {
       std::istringstream iss(line);
       int a, b;
       if (!(iss >> a >> b)) { break; } // error
   
       // process pair (a,b)
   }
   

You shouldn't mix (1) and (2), since the token-based parsing doesn't gobble up newlines, so you may end up with spurious empty lines if you use getline() after token-based extraction got you to the end of a line already.

An investment in learning VIM (my preference) or EMACS will pay off.

I suggest visiting Derek Wyatt's site, running through the VIM Tutor, and checking out the Steve Oualine PDF book.

Vim helps me move around and edit quicker than other editors I've used. My work IDEs are quite limited in what they allow one to do and are typically devoted to a particular environment. There are tasks that still require me to revisit the IDE (such as debuggers which are a compiled part of the IDE).

This work for me :

sudo service redis-server start

The magic number comes from UNIX-type systems where the first few bytes of a file held a marker indicating the file type.

Python puts a similar marker into its pyc files when it creates them.

Then the python interpreter makes sure this number is correct when loading it.

Anything that damages this magic number will cause your problem. This includes editing the pyc file or trying to run a pyc from a different version of python (usually later) than your interpreter.

If they are your pyc files, just delete them and let the interpreter re-compile the py files. On UNIX type systems, that could be something as simple as:

rm *.pyc

or:

find . -name '*.pyc' -delete

If they are not yours, you'll have to either get the py files for re-compilation, or an interpreter that can run the pyc files with that particular magic value.

One thing that might be causing the intermittent nature. The pyc that's causing the problem may only be imported under certain conditions. It's highly unlikely it would import sometimes. You should check the actual full stack trace when the import fails?

As an aside, the first word of all my 2.5.1(r251:54863) pyc files is 62131, 2.6.1(r261:67517) is 62161. The list of all magic numbers can be found in Python/import.c, reproduced here for completeness (current as at the time the answer was posted, it may have changed since then):

In html

button ng-click="myMethod()">Videos</button>

It is very convenient to use train_test_split without performing reindexing after dividing to several sets and not writing some additional code. Best answer above does not mention that by separating two times using train_test_split not changing partition sizes won`t give initially intended partition:

x_train, x_remain = train_test_split(x, test_size=(val_size + test_size))

Then the portion of validation and test sets in the x_remain change and could be counted as

new_test_size = np.around(test_size / (val_size + test_size), 2)
# To preserve (new_test_size + new_val_size) = 1.0 
new_val_size = 1.0 - new_test_size

x_val, x_test = train_test_split(x_remain, test_size=new_test_size)

In this occasion all initial partitions are saved.

ng-bind="reviewData.dateValue.replace('/Date(','').replace(')/','') | date:'MM/dd/yyyy'"

Use this should work well. :) The reviewData and dateValue fields can be changes as per your parameter rest can be left same

The following query only list the required data, whereas the other answers gave me the extra data which only confused me.

select table_name from user_tables;

1. https://hub.docker.com/search?q=* shows all the images in the entire Docker hub, it's not possible to get this via the search command as it doesnt accept wildcards.

2. As of v1.10 you can find all the layers in an image by pulling it and using these commands:

   docker pull ubuntu
   ID=$(sudo docker inspect -f {{.Id}} ubuntu)
   jq .rootfs.diff_ids /var/lib/docker/image/aufs/imagedb/content/$(echo $ID|tr ':' '/')
   

3) The size can be found in /var/lib/docker/image/aufs/layerdb/sha256/{LAYERID}/size although LAYERID != the diff_ids found with the previous command. For this you need to look at /var/lib/docker/image/aufs/layerdb/sha256/{LAYERID}/diff and compare with the previous command output to properly match the correct diff_id and size.

#1 form

a = ('x', 'y')

b = a + tuple('b')
print(b)

You can define UTF-8 .properties files to store your translations and use ResourceBundle, to get values. To avoid problems you can change encoding:

String value = RESOURCE_BUNDLE.getString(key); 
return new String(value.getBytes("ISO-8859-1"), "UTF-8");

• Deep copy: Clone this object and every reference to every other object it has
• Shallow copy: Clone this object and keep its references
• Object clone() throws CloneNotSupportedException: It is not specified whether this should return a deep or shallow copy, but at the very least: o.clone() != o

This is similar to aSeptik's answer, but what about this approach? Wrap the CSS code which you want to disable using JavaScript in <noscript> tags. That way if javaScript is off, the CSS :hover will be used, otherwise the JavaScript effect will be used.

Example:

<noscript>
<style type="text/css">
ul#mainFilter a:hover {
  /* some CSS attributes here */
}
</style>
</noscript>
<script type="text/javascript">
$("ul#mainFilter a").hover(
     function(o){ /* ...do your stuff... */ }, 
     function(o){ /* ...do your stuff... */ });
</script>

If java command is working and getting problem with javac. then first check in jdk's bin directory javac.exe file is there or not. If javac.exe file is exist then set JAVA_HOME as System variable.

You're getting final 0 because your while loop is being executed in a sub (shell) process and any changes made there are not reflected in the current (parent) shell.

Correct script:

while read -r country _; do
  if [ "US" = "$country" ]; then
        ((USCOUNTER++))
        echo "US counter $USCOUNTER"
  fi
done < "$FILE"

One caution based on my experience, if your purpose only involves date then be careful to include the timestamp. For example, say today is "2016-11-09". Comparison involving timestamp will nullify the logic here. Example,

//  input
$var = "2016-11-09 00:00:00.0";

//  check if date is today or in the future
if ( time() <= strtotime($var) ) 
{
    //  This seems right, but if it's ONLY date you are after
    //  then the code might treat $var as past depending on
    //  the time.
}

The code above seems right, but if it's ONLY the date you want to compare, then, the above code is not the right logic. Why? Because, time() and strtotime() will provide include timestamp. That is, even though both dates fall on the same day, but difference in time will matter. Consider the example below:

//  plain date string
$input = "2016-11-09";

Because the input is plain date string, using strtotime() on $input will assume that it's the midnight of 2016-11-09. So, running time() anytime after midnight will always treat $input as past, even though they are on the same day.

To fix this, you can simply code, like this:

if (date("Y-m-d") <= $input)
{
    echo "Input date is equal to or greater than today.";
}

I refactored your code a bit and believe I came with the solution for which you were looking. Basically instead of setting searchIDs to be the result of the .map() I just pushed the values into an array.

$("#merge_button").click(function(event){
  event.preventDefault();

  var searchIDs = [];

  $("#find-table input:checkbox:checked").map(function(){
    searchIDs.push($(this).val());
  });

  console.log(searchIDs);
});

I created a fiddle with the code running.

Command Line

Create a file named tmp.html with the following contents:

<b>my bold message</b>

Next, paste the following into the command line (parentheses and all):

(
  echo To: [email protected]
  echo From: [email protected]
  echo "Content-Type: text/html; "
  echo Subject: a logfile
  echo
  cat tmp.html
) | sendmail -t

The mail will be dispatched including a bold message due to the <b> element.

Shell Script

As a script, save the following as email.sh:

ARG_EMAIL_TO="[email protected]"
ARG_EMAIL_FROM="Your Name <[email protected]>"
ARG_EMAIL_SUBJECT="Subject Line"

(
  echo "To: ${ARG_EMAIL_TO}"
  echo "From: ${ARG_EMAIL_FROM}"
  echo "Subject: ${ARG_EMAIL_SUBJECT}"
  echo "Mime-Version: 1.0"
  echo "Content-Type: text/html; charset='utf-8'"
  echo
  cat contents.html
) | sendmail -t

Create a file named contents.html in the same directory as the email.sh script that resembles:

<html><head><title>Subject Line</title></head>
<body>
  <p style='color:red'>HTML Content</p>
</body>
</html>

Run email.sh. When the email arrives, the HTML Content text will appear red.

I had an array of strings, not objects and i used this approach:

ng-repeat="name in names | unique"

with this filter:

angular.module('app').filter('unique', unique);
function unique(){
return function(arry){
        Array.prototype.getUnique = function(){
        var u = {}, a = [];
        for(var i = 0, l = this.length; i < l; ++i){
           if(u.hasOwnProperty(this[i])) {
              continue;
           }
           a.push(this[i]);
           u[this[i]] = 1;
        }
        return a;
    };
    if(arry === undefined || arry.length === 0){
          return '';
    }
    else {
         return arry.getUnique(); 
    }

  };
}

Once when I was interviewing for Microsoft in college, the guy asked me how to detect a cycle in a linked list.

Having discussed in class the prior week the optimal solution to the problem, I started to tell him.

He told me, "No, no, everybody gives me that solution. Give me a different one."

I argued that my solution was optimal. He said, "I know it's optimal. Give me a sub-optimal one."

At the same time, it's a pretty good problem.

You are sending a POST AJAX request so use $albumname = $_POST['album']; on your server to fetch the value. Also I would recommend you writing the request like this in order to ensure proper encoding:

$.ajax({  
    type: 'POST',  
    url: 'test.php', 
    data: { album: this.title },
    success: function(response) {
        content.html(response);
    }
});

or in its shorter form:

$.post('test.php', { album: this.title }, function() {
    content.html(response);
});

and if you wanted to use a GET request:

$.ajax({  
    type: 'GET',
    url: 'test.php', 
    data: { album: this.title },
    success: function(response) {
        content.html(response);
    }
});

or in its shorter form:

$.get('test.php', { album: this.title }, function() {
    content.html(response);
});

and now on your server you wil be able to use $albumname = $_GET['album'];. Be careful though with AJAX GET requests as they might be cached by some browsers. To avoid caching them you could set the cache: false setting.

You could also use tools provided by the base JRE:

String msg = "<message>HELLO!</message>";
DocumentBuilder newDocumentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document parse = newDocumentBuilder.parse(new ByteArrayInputStream(msg.getBytes()));
System.out.println(parse.getFirstChild().getTextContent());

A really, really fast implementation which was ported (and modified/improved) from the PHP Core library into native Objective-C code is available in the QSStrings Class from the QSUtilities Library. I did a quick benchmark: a 5.3MB image (JPEG) file took < 50ms to encode, and about 140ms to decode.

The code for the entire library (including the Base64 Methods) are available on GitHub.

Or alternatively, if you want the code to just the Base64 methods themselves, I've posted it here:

First, you need the mapping tables:

static const char _base64EncodingTable[64] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
static const short _base64DecodingTable[256] = {
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -1, -1, -2, -1, -1, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -1, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, 62, -2, -2, -2, 63,
    52, 53, 54, 55, 56, 57, 58, 59, 60, 61, -2, -2, -2, -2, -2, -2,
    -2,  0,  1,  2,  3,  4,  5,  6,  7,  8,  9, 10, 11, 12, 13, 14,
    15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, -2, -2, -2, -2, -2,
    -2, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40,
    41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
    -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2
};

To Encode:

+ (NSString *)encodeBase64WithString:(NSString *)strData {
    return [QSStrings encodeBase64WithData:[strData dataUsingEncoding:NSUTF8StringEncoding]];
}

+ (NSString *)encodeBase64WithData:(NSData *)objData {
    const unsigned char * objRawData = [objData bytes];
    char * objPointer;
    char * strResult;

    // Get the Raw Data length and ensure we actually have data
    int intLength = [objData length];
    if (intLength == 0) return nil;

    // Setup the String-based Result placeholder and pointer within that placeholder
    strResult = (char *)calloc((((intLength + 2) / 3) * 4) + 1, sizeof(char));
    objPointer = strResult;

    // Iterate through everything
    while (intLength > 2) { // keep going until we have less than 24 bits
        *objPointer++ = _base64EncodingTable[objRawData[0] >> 2];
        *objPointer++ = _base64EncodingTable[((objRawData[0] & 0x03) << 4) + (objRawData[1] >> 4)];
        *objPointer++ = _base64EncodingTable[((objRawData[1] & 0x0f) << 2) + (objRawData[2] >> 6)];
        *objPointer++ = _base64EncodingTable[objRawData[2] & 0x3f];

        // we just handled 3 octets (24 bits) of data
        objRawData += 3;
        intLength -= 3; 
    }

    // now deal with the tail end of things
    if (intLength != 0) {

Try using the html() function.

$('#<%=Label1.ClientID%>').html();

You're also missing the # to make it an ID you're searching for. Without the #, it's looking for a tag type.

In the above solution, repeated here:

f = open('file.txt', 'r')

try:
    # do stuff with f
finally:
   f.close()

if something bad happens (you never know ...) after opening the file successfully and before the try, the file will not be closed, so a safer solution is:

f = None
try:
    f = open('file.txt', 'r')

    # do stuff with f

finally:
    if f is not None:
       f.close()

An alternate method that limits the scope of the lambda rather than giving it access to the whole this is to pass in a local reference to the member variable, e.g.

auto& localGrid = grid;
int i;
for_each(groups.cbegin(),groups.cend(),[localGrid,&i](pair<int,set<int>> group){
            i++;
            cout<<i<<endl;
   });

Another reason why people might struggle to get Syntax Highlighting working is because they don't have the appropriate syntax package installed. While some default syntax packages come pre-installed (like Swift, C, JS, CSS), others may not be available.

To solve this you can Cmd + Shift + P ? "install Extensions" and look for the language you want to add, say "Scala".

Find the suitable Syntax package, install it and reload. This will pick up the correct syntax for your files with the predefined extension, i.e. .scala in this case.

On top of that you might want VS Code to treat all files with certain custom extensions as your preferred language of choice. Let's say you want to highlight all *.es files as JavaScript, then just open "User Settings" (Cmd + Shift + P ? "User Settings") and configure your custom files association like so:

  "files.associations": {
    "*.es": "javascript"
  },

Since C99, C has 2D arrays with dynamical bounds. If you want to avoid that such beast are allocated on the stack (which you should), you can allocate them easily in one go as the following

double (*A)[n] = malloc(sizeof(double[n][n]));

and that's it. You can then easily use it as you are used for 2D arrays with something like A[i][j]. And don't forget that one at the end

free(A);

Randy Meyers wrote series of articles explaining variable length arrays (VLAs).

You can use us jquery function getJson :

$(function(){
    $.getJSON('/api/rest/abc', function(data) {
        console.log(data);
    });
});

Often, wild cards operate with two type of jokers:

  ? - any character  (one and only one)
  * - any characters (zero or more)

so you can easily convert these rules into appropriate regular expression:

  // If you want to implement both "*" and "?"
  private static String WildCardToRegular(String value) {
    return "^" + Regex.Escape(value).Replace("\\?", ".").Replace("\\*", ".*") + "$"; 
  }

  // If you want to implement "*" only
  private static String WildCardToRegular(String value) {
    return "^" + Regex.Escape(value).Replace("\\*", ".*") + "$"; 
  }

And then you can use Regex as usual:

  String test = "Some Data X";

  Boolean endsWithEx = Regex.IsMatch(test, WildCardToRegular("*X"));
  Boolean startsWithS = Regex.IsMatch(test, WildCardToRegular("S*"));
  Boolean containsD = Regex.IsMatch(test, WildCardToRegular("*D*"));

  // Starts with S, ends with X, contains "me" and "a" (in that order) 
  Boolean complex = Regex.IsMatch(test, WildCardToRegular("S*me*a*X"));

According to the flask.Request.args documents.

flask.Request.args
A MultiDict with the parsed contents of the query string. (The part in the URL after the question mark).

So the args.get() is method get() for MultiDict, whose prototype is as follows:

get(key, default=None, type=None)

Update:
In newer version of flask (v1.0.x and v1.1.x), flask.Request.args is an ImmutableMultiDict(an immutable MultiDict), so the prototype and specific method above is still valid.

Here is something you could try.

Add this to any config files you use to run your app.

ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../../Gemfile', __FILE__)
require 'bundler/setup' # Set up gems listed in the Gemfile.
Bundler.require(:default)

Rails and other Rack based apps use this scheme. It happens sometimes that you are trying to run things which are some directories deeper than your root where your Gemfile normally is located. Of course you solved this problem for now but occasionally we all get into trouble with this finding the Gemfile. I sometimes like when you can have all you gems in the .bundle directory also. It never hurts to keep this site address under your pillow. http://bundler.io/

You need to do encode on tmp[0], not on tmp.

tmp is not a string. It contains a (Unicode) string.

Try running type(tmp) and print dir(tmp) to see it for yourself.

Update:

Read the Docs for your version of Django. e.g.

https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/3.0/ref/contrib/admin/#admin-overriding-templates

Original answer from 2011:

I had the same issue about a year and a half ago and I found a nice template loader on djangosnippets.org that makes this easy. It allows you to extend a template in a specific app, giving you the ability to create your own admin/index.html that extends the admin/index.html template from the admin app. Like this:

{% extends "admin:admin/index.html" %}

{% block sidebar %}
    {{block.super}}
    <div>
        <h1>Extra links</h1>
        <a href="/admin/extra/">My extra link</a>
    </div>
{% endblock %}

I've given a full example on how to use this template loader in a blog post on my website.

If the files are not gigantic:

with open('newfile.txt','wb') as newf:
    for filename in list_of_files:
        with open(filename,'rb') as hf:
            newf.write(hf.read())
            # newf.write('\n\n\n')   if you want to introduce
            # some blank lines between the contents of the copied files

If the files are too big to be entirely read and held in RAM, the algorithm must be a little different to read each file to be copied in a loop by chunks of fixed length, using read(10000) for example.

For the line-end thingie, refer to man git-merge:

--ignore-space-change 
--ignore-all-space 
--ignore-space-at-eol

Be sure to add autocrlf = false and/or safecrlf = false to the windows clone (.git/config)

Using git mergetool

If you configure a mergetool like this:

git config mergetool.cp.cmd '/bin/cp -v "$REMOTE" "$MERGED"'
git config mergetool.cp.trustExitCode true

Then a simple

git mergetool --tool=cp
git mergetool --tool=cp -- paths/to/files.txt
git mergetool --tool=cp -y -- paths/to/files.txt # without prompting

Will do the job

Using simple git commands

In other cases, I assume

git checkout HEAD -- path/to/myfile.txt

should do the trick

Edit to do the reverse (because you screwed up):

git checkout remote/branch_to_merge -- path/to/myfile.txt

If all else fails and you are using Gulp or something similar...just rerun it!

I wasted 30mins quadruple checking everything when all it needed was a swift kick in the pants.

The results might seem similar, but that is just because of the Taylor expansion for the logarithm. Since log(1 + x) ~ x, the results can be similar.

However,

I am using the following code to get logarithmic returns, but it gives the exact same values as the pct.change() function.

is not quite correct.

import pandas as pd

df = pd.DataFrame({'p': range(10)})

df['pct_change'] = df.pct_change()
df['log_stuff'] = \
    np.log(df['p'].astype('float64')/df['p'].astype('float64').shift(1))
df[['pct_change', 'log_stuff']].plot();

To complete,

In a shell (bash) script, you can use \r to send cursor, in front on line and, of course \n to put cursor on a new line.

For example, try :

echo -en "AA--AA" ; echo -en "BB" ; echo -en "\rBB"

• The first "echo" display AA--AA
• The second : AA--AABB
• The last : BB--AABB

But don't forget to use -en as parameters.

I looked into this a bit more and the actual problem seems to be with assigning initial to page width under the print media rule. It seems like in Chrome width: initial on the .page element results in scaling of the page content if no specific length value is defined for width on any of the parent elements (width: initial in this case resolves to width: auto ... but actually any value smaller than the size defined under the @page rule causes the same issue).

So not only the content is now too long for the page (by about 2cm), but also the page padding will be slightly more than the initial 2cm and so on (it seems to render the contents under width: auto to the width of ~196mm and then scale the whole content up to the width of 210mm ~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm).

To fix this problem you can simply in the print media rule assign the A4 paper width and hight to html, body or directly to .page and in this case avoid the initial keyword.

DEMO

@page {
  size: A4;
  margin: 0;
}
@media print {
  html, body {
    width: 210mm;
    height: 297mm;
  }
  /* ... the rest of the rules ... */
}

^{This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).}

SwiftUI - Full Example

import SwiftUI

struct ContentView: View {
    
    @State private var text = defaultText
    
    @State private var isKeyboardShowing = false
    
    private static let defaultText = "write something..."
    
    private var gesture = TapGesture().onEnded({_ in
        UIApplication.shared.endEditing(true)
    })
    
    var body: some View {
        
        ZStack {
            Color.black
            
            VStack(alignment: .leading) {
                TextField("placeholder", text: $text)
                    .foregroundColor(.white)
                    .padding()
                    .background(Color.green)
            }
            
            .padding()
        }
        .edgesIgnoringSafeArea(.all)
        .onChange(of: isKeyboardShowing, perform: { (isShowing) in
            if isShowing {
                if text == Self.defaultText { text = "" }
            } else {
                if text == "" { text = Self.defaultText }
            }
        })
        .simultaneousGesture(gesture)
        .onReceive(NotificationCenter.default
                    .publisher(for: UIResponder.keyboardWillShowNotification), perform: { (value) in
                        isKeyboardShowing = true
                    })
        .onReceive(NotificationCenter.default
                    .publisher(for: UIResponder.keyboardWillHideNotification), perform: { (value) in
                        isKeyboardShowing = false

    }
}

extension UIApplication {
    func endEditing(_ force: Bool) {
        self.windows
            .filter{$0.isKeyWindow}
            .first?
            .endEditing(force)
    }
}

This is because of a higher JDK during compile time and lower JDK during runtime. So you just need to update your JDK version, possible to JDK 7

You may also check Unsupported major.minor version 51.0

Your two statements are equivalent.

Most people only use LEFT JOIN since it seems more intuitive, and it's universal syntax - I don't think all RDBMS support RIGHT JOIN.

I had a similar problem when migrating an old database to a new version.

Switch the MySQL mode to not use STRICT.

SET @@global.sql_mode= 'NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

Error Code: 1406. Data too long for column - MySQL

In browsers other than Internet Explorer, you can pass parameters to the function together after the delay:

var timeoutID = window.setTimeout(func, delay, [param1, param2, ...]);

So, you can do this:

var timeoutID = window.setTimeout(function (self) {
  console.log(self); 
}, 500, this);

This is better in terms of performance than a scope lookup (caching this into a variable outside of the timeout / interval expression), and then creating a closure (by using $.proxy or Function.prototype.bind).

The code to make it work in IEs from Webreflection:

/*@cc_on
(function (modifierFn) {
  // you have to invoke it as `window`'s property so, `window.setTimeout`
  window.setTimeout = modifierFn(window.setTimeout);
  window.setInterval = modifierFn(window.setInterval);
})(function (originalTimerFn) {
    return function (callback, timeout){
      var args = [].slice.call(arguments, 2);
      return originalTimerFn(function () { 
        callback.apply(this, args) 
      }, timeout);
    }
});
@*/

Instead of using

int * p;
p = {1,2,3};

we can use

int * p;
p =(int[3]){1,2,3};

On OSX, for me it's cmd ? + p. cmd ? + e just searches within the currently opened file.

there is a ngcontentloaded event, I think you can use it

.directive('directiveExample', function(){
   return {
       restrict: 'A',
       link: function(scope, elem, attrs){

                $$window = $ $window


                init = function(){
                    contentHeight = elem.outerHeight()
                    //do the things
                }

                $$window.on('ngcontentloaded',init)

       }
   }
});

In case you have to download a file with a size larger than the allowed memory limit (memory_limit ini setting), which would cause the PHP Fatal error: Allowed memory size of 5242880 bytes exhausted error, you can do this:

// File to download.
$file = '/path/to/file';

// Maximum size of chunks (in bytes).
$maxRead = 1 * 1024 * 1024; // 1MB

// Give a nice name to your download.
$fileName = 'download_file.txt';

// Open a file in read mode.
$fh = fopen($file, 'r');

// These headers will force download on browser,
// and set the custom file name for the download, respectively.
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $fileName . '"');

// Run this until we have read the whole file.
// feof (eof means "end of file") returns `true` when the handler
// has reached the end of file.
while (!feof($fh)) {
    // Read and output the next chunk.
    echo fread($fh, $maxRead);

    // Flush the output buffer to free memory.
    ob_flush();
}

// Exit to make sure not to output anything else.
exit;

I got the error in the following case:

1. A .NET EXE file (#1) was referencing another .NET EXE file (#2)
2. I was trying to obfuscate EXE #2 with Themida
3. when running the EXE #1 it was crashing with the error "The module was expected to contain an assembly manifest"

I simply avoided the obfuscation and the error is gone. not a real solution, but at least I know what caused it...

Points to keep in mind:

1. Pointers can be NULL, references cannot be NULL.

2. References are easier to use, const can be used for a reference when we don't want to change value and just need a reference in a function.

3. Pointer used with a * while references used with a &.

4. Use pointers when pointer arithmetic operation are required.

5. You can have pointers to a void type int a=5; void *p = &a; but cannot have a reference to a void type.

Pointer Vs Reference

void fun(int *a)
{
    cout<<a<<'\n'; // address of a = 0x7fff79f83eac
    cout<<*a<<'\n'; // value at a = 5
    cout<<a+1<<'\n'; // address of a increment by 4 bytes(int) = 0x7fff79f83eb0
    cout<<*(a+1)<<'\n'; // value here is by default = 0
}
void fun(int &a)
{
    cout<<a<<'\n'; // reference of original a passed a = 5
}
int a=5;
fun(&a);
fun(a);

Verdict when to use what

Pointer: For array, linklist, tree implementations and pointer arithmetic.

Reference: In function parameters and return types.

jQuery(document).ready(function(){
   jQuery(".head h3").html('Public Offers');
});

You can use default primary key (id) which auto increaments.

Note: When you use first design i.e. use default field (id) as a primary key, initialize object by mentioning column names. e.g.

class User(models.Model):
    user_name = models.CharField(max_length = 100)

then initialize,

user = User(user_name="XYZ")

if you initialize in following way,

user = User("XYZ")

then python will try to set id = "XYZ" which will give you error on data type.

1.First Create an xml file in drawable folder under resource

named "progress.xml"

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="360" >

    <shape
        android:innerRadiusRatio="3"
        android:shape="ring"
        android:thicknessRatio="8"
        android:useLevel="false" >

    <size
        android:height="76dip"
        android:width="76dip" />

    <gradient
        android:angle="0"
        android:endColor="color/pink"
        android:startColor="@android:color/transparent"
        android:type="sweep"
        android:useLevel="false" />

    </shape>

</rotate>

2.then make a progresss bar using the folloing snippet

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/relativeLayout1"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="20dp"
    android:indeterminate="true"
    android:indeterminateDrawable="@drawable/progress" />

Member references are usually considered bad. They make life hard compared to member pointers. But it's not particularly unsual, nor is it some special named idiom or thing. It's just aliasing.

C++ has NULL as well, often the same as 0 (pointer to address 0x00000000).

Do you use NULL or 0 (zero) for pointers in C++?

So in C++ that null check would be:

 if (!foo)
    cout << "not found";

maybe you are having the same problem i had, my tablet has a SD card on it, in /mnt/sdcard and the sd card external was in /mnt/extcard, you can look it on the android file manager, going to your sd card and see the path to it.

Hope it helps.

I discovered that I had to include

body { width:100%; }

for "margin: 0 auto" to work for tables.

Even after going through many posts, it took several hours to figure out the problem. Here is the detailed approach written in simple language to run python via command line in windows.

1. Download executable file from python.org
Choose the latest version and download Windows-executable installer. Execute the downloaded file and let installation complete.

2. Ensure the file is downloaded in some administrator folder

1. Search file location of Python application.
2. Right click on the .exe file and navigate to its properties. Check if it is of the form, "C:\Users....". If NO, you are good to go and jump to step 3. Otherwise, clone the Python37 or whatever version you downloaded to one of these locations, "C:\", "C:\Program Files", "C:\Program Files (x86)".
   

3. Update the system PATH variable This is the most crucial step and there are two ways to do this:- (Follow the second one preferably)

1. MANUALLY
- Search for 'Edit the system Environment Variables' in the search bar.(WINDOWS 10)
- In the System Properties dialog, navigate to "Environment Variables".
- In the Environment Variables dialog look for "Path" under the System Variables window. (# Ensure to click on Path under bottom window named System Variables and not under user variables)
- Edit the Path Variable by adding location of Python37/ PythonXX folder. I added following line:-
" ;C:\Program Files (x86)\Python37;C:\Program Files (x86)\Python37\Scripts "
- Click Ok and close the dialogs.

2. SCRIPTED
- Open the command prompt and navigate to Python37/XX folder using cd command.
- Write the following statement:-
"python.exe Tools\Scripts\win_add2path.py"

You can now use python in the command prompt:)
1. Using Shell
Type python in cmd and use it.
2. Executing a .py file
Type python filename.py to execute it.

Try changing this:

new_DF<-dplyr::filter(DF,is.na(Var2)) 

Maybe good ol' cfront will do?

    if d['apples'] == 20:
        print('20 apples')
    else:
        print('Not 20 apples')

If you want to get the value only if the key exists (and avoid an exception trying to get it if it doesn't), then you can use the get function from a dictionary, passing an optional default value as the second argument (if you don't pass it it returns None instead):

if d.get('apples', 0) == 20:
    print('20 apples.')
else:
    print('Not 20 apples.')

It took me some time to get familiarized with the higher order functions filter and map. So i got used to them and i actually liked filter as it was explicit that it filters by keeping whatever is truthy and I've felt cool that I knew some functional programming terms.

Then I read this passage (Fluent Python Book):

The map and filter functions are still builtins in Python 3, but since the introduction of list comprehensions and generator ex- pressions, they are not as important. A listcomp or a genexp does the job of map and filter combined, but is more readable.

And now I think, why bother with the concept of filter / map if you can achieve it with already widely spread idioms like list comprehensions. Furthermore maps and filters are kind of functions. In this case I prefer using Anonymous functions lambdas.

Finally, just for the sake of having it tested, I've timed both methods (map and listComp) and I didn't see any relevant speed difference that would justify making arguments about it.

from timeit import Timer

timeMap = Timer(lambda: list(map(lambda x: x*x, range(10**7))))
print(timeMap.timeit(number=100))

timeListComp = Timer(lambda:[(lambda x: x*x) for x in range(10**7)])
print(timeListComp.timeit(number=100))

#Map:                 166.95695265199174
#List Comprehension   177.97208347299602

I face same problem when install Scipy under ubuntu.
I had to use command:

$ sudo apt-get install libatlas-base-dev gfortran
$ sudo pip3 install scipy

Sorry don't know how to do it under OS X Yosemite.

How about:

<table>
  <tr ng-repeat="(key, value) in data">
    <td> {{key}} </td> <td> {{ value }} </td>
  </tr>
</table>

This method is listed in the docs: https://docs.angularjs.org/api/ng/directive/ngRepeat

Building on @Rob Neild's answer above, here is a pure JS adaptation that returns a simple object of decoded query string params (no %20's, etc).

function parseQueryString () {
  var parsedParameters = {},
    uriParameters = location.search.substr(1).split('&');

  for (var i = 0; i < uriParameters.length; i++) {
    var parameter = uriParameters[i].split('=');
    parsedParameters[parameter[0]] = decodeURIComponent(parameter[1]);
  }

  return parsedParameters;
}

Here's a batch script I made to return a timestamp. An optional first argument may be provided to be used as a field delimiter. For example:

c:\sys\tmp>timestamp.bat
20160404_144741
c:\sys\tmp>timestamp.bat -
2016-04-04_14-45-25
c:\sys\tmp>timestamp.bat :
2016:04:04_14:45:29

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
:: put your desired field delimiter here.
:: for example, setting DELIMITER to a hyphen will separate fields like so:
:: yyyy-MM-dd_hh-mm-ss
::
:: setting DELIMITER to nothing will output like so:
:: yyyyMMdd_hhmmss
::
SET DELIMITER=%1

SET DATESTRING=%date:~-4,4%%DELIMITER%%date:~-7,2%%DELIMITER%%date:~-10,2%
SET TIMESTRING=%TIME%
::TRIM OFF the LAST 3 characters of TIMESTRING, which is the decimal point and hundredths of a second
set TIMESTRING=%TIMESTRING:~0,-3%

:: Replace colons from TIMESTRING with DELIMITER
SET TIMESTRING=%TIMESTRING::=!DELIMITER!%

:: if there is a preceeding space substitute with a zero
echo %DATESTRING%_%TIMESTRING: =0%

I had that issue and I solved by doing this:

.done(function() {
                    $(this).find("input").val("");
                    $("#feedback").trigger("reset");
                });

I added this code after my script as I used jQuery. Try same)

<script type="text/JavaScript">

        $(document).ready(function() {
            $("#feedback").submit(function(event) {
                event.preventDefault();
                $.ajax({
                    url: "feedback_lib.php",
                    type: "post",
                    data: $("#feedback").serialize()
                }).done(function() {
                    $(this).find("input").val("");
                    $("#feedback").trigger("reset");
                });
            });
        });
    </script>
    <form id="feedback" action="" name="feedback" method="post">
        <input id="name" name="name" placeholder="name" />
        <br />
        <input id="surname" name="surname" placeholder="surname" />
        <br />
        <input id="enquiry" name="enquiry" placeholder="enquiry" />
        <br />
        <input id="organisation" name="organisation" placeholder="organisation" />
        <br />
        <input id="email" name="email" placeholder="email" />
        <br />
        <textarea id="message" name="message" rows="7" cols="40" placeholder="?????????"></textarea>
        <br />
        <button id="send" name="send">send</button>
    </form>

You can use the 'jQuery Passthrough' module of the angular-ui utils. I successfully binded a jQuery touch carousel plugin to some images that I retrieve async from a web service and render them with ng-repeat.

If you're brand new to using unittests, the simplest approach to learn is often the best. On that basis along I recommend using py.test rather than the default unittest module.

Consider these two examples, which do the same thing:

Example 1 (unittest):

import unittest

class LearningCase(unittest.TestCase):
    def test_starting_out(self):
        self.assertEqual(1, 1)

def main():
    unittest.main()

if __name__ == "__main__":
    main()

Example 2 (pytest):

def test_starting_out():
    assert 1 == 1

Assuming that both files are named test_unittesting.py, how do we run the tests?

Example 1 (unittest):

cd /path/to/dir/
python test_unittesting.py

Example 2 (pytest):

cd /path/to/dir/
py.test

Syntax errors is not checked easily in external servers, just runtime errors.

What I do? Just like you, I use

ini_set('display_errors', 'On');
error_reporting(E_ALL);

However, before run I check syntax errors in a PHP file using an online PHP syntax checker.

The best, IMHO is PHP Code Checker

I copy all the source code, paste inside the main box and click the Analyze button.

It is not the most practical method, but the 2 procedures are complementary and it solves the problem completely

Option 1: select the cell(s), under formatting/number/custom formatting, type in

"BOB" General

now you have a prefix "BOB" next to numbers, dates, booleans, but not next to TEXTs

Option2: As before, but use the following format

_ "BOB" @_

now you have a prefix BOB, this works even if the cell contained text

From jQuery's website

Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: $(elem).css('marginTop') and $(elem).css('marginRight'), and so on.

type Services at search, then start Services

then start all VM services

For Java applications, i.e. programs that are delivered (usually) as .jar files and started with java -jar xxx.jar or via a shortcut that does the same, the JRE that will be launched will be the first one found on the PATH.

If you installed a JRE or JDK, the likely places to find the .exes are below directories like C:\Program Files\JavaSoft\JRE\x.y.z. However, I've found some "out of the box" Windows installations to (also?) have copies of java.exe and javaw.exe in C:\winnt\system32 (NT and 2000) or C:\windows\system (Windows 95, 98). This is usually a pretty elderly version of Java: 1.3, maybe? You'll want to do java -version in a command window to check that you're not running some antiquated version of Java.

You can of course override the PATH setting or even do without it by explicitly stating the path to java.exe / javaw.exe in your command line or shortcut definition.

If you're running applets from the browser, or possibly also Java Web Start applications (they look like applications insofar as they have their own window, but you start them from the browser), the choice of JRE is determined by a set of registry settings:

Key: HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment
Name: CurrentVersion
Value: (e.g.) 1.3

More registry keys are created using this scheme:

(e.g.) 
HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment\1.3   
HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment\1.3.1

i.e. one for the major and one including the minor version number. Each of these keys has values like these (examples shown):

JavaHome    : C:\program Files\JavaSoft\JRE\1.3.1
RuntimeLib  : C:\Program Files\JavaSoft\JRE\1.3.1\bin\hotspot\jvm.dll
MicroVersion: 1

... and your browser will look to these settings to determine which JRE to fire up.

Since Java versions are changing pretty frequently, there's now a "wizard" called the "Java Control Panel" for manually switching your browser's Java version. This works for IE, Firefox and probably others like Opera and Chrome as well: It's the 'Java' applet in Windows' System Settings app. You get to pick any one of the installed JREs. I believe that wizard fiddles with those registry entries.

If you're like me and have "uninstalled" old Java versions by simply wiping out directories, you'll find these "ghosts" among the choices too; so make sure the JRE you choose corresponds to an intact Java installation!

Some other answers are recommending setting the environment variable JAVA_HOME. This is meanwhile outdated advice. Sun came to realize, around Java 2, that this environment setting is

1. unreliable, as users often set it incorrectly, and
2. unnecessary, as it's easy enough for the runtime to find the Java library directories, knowing they're in a fixed path relative to the path from which java.exe or javaw.exe was launched.

There's hardly any modern Java software left that needs or respects the JAVA_HOME environment variable.

You cannot create a backup from a remote server to a local disk - there is just no way to do this. And there are no third-party tools to do this either, as far as I know.

All you can do is create a backup on the remote server machine, and have someone zip it up and send it to you.

You will need to add external Repository to your pom, since this is using Mulsoft-Release repository not Maven Central

For me no work i need upgrade pip....

Debian/Ubuntu

install dependencies

sudo apt-get install libpython-dev libssl-dev libffi-dev

upgrade pip and install packages

sudo pip install -U pip
sudo pip install -U pyopenssl ndg-httpsclient pyasn1

If you want remove dependencies

sudo apt-get remove --purge libpython-dev libssl-dev libffi-dev
sudo apt-get autoremove

Best example for dynamic linking is, when the library is dependent on the used hardware. In ancient times the C math library was decided to be dynamic, so that each platform can use all processor capabilities to optimize it.

An even better example might be OpenGL. OpenGl is an API that is implemented differently by AMD and NVidia. And you are not able to use an NVidia implementation on an AMD card, because the hardware is different. You cannot link OpenGL statically into your program, because of that. Dynamic linking is used here to let the API be optimized for all platforms.

IMDB doesn't seem to have a direct API as of August 2016 yet but I saw many people writing scrapers and stuff above. Here is a more standard way to access movie data using box office buzz API. All responses in JSON format and 5000 queries per day on a free plan

List of things provided by the API

1. Movie Credits
2. Movie ID
3. Movie Images
4. Get movie by IMDB id
5. Get latest movies list
6. Get new releases
7. Get movie release dates
8. Get the list of translations available for a specific movie
9. Get videos, trailers, and teasers for a movie
10. Search for a movie by title
11. Also supports TV shows, games and videos

Although it's too late , But here is my experience .

Whenever you get your maven project from a source controller or just copying your project from one machine to another , you need to update the dependencies .

For this Right-click on Project on project explorer -> Maven -> Update Project.

Please consider checking the "Force update of snapshot/releases" checkbox.

If you have not your dependencies in m2/repository then you need internet connection to get from the remote maven repository.

In case you have get from the source controller and you have not any unit test , It's probably your test folder does not include in the source controller in the first place , so you don't have those in the new repository.so you need to create those folders manually.

I have had both these cases .

I had this error message with boot2docker on windows with the docker-oracle-xe-11g image (https://registry.hub.docker.com/u/wnameless/oracle-xe-11g/).

The reason was that the virtual box disk was full (check with boot2docker.exe ssh df). Deleting old images and restarting the container solved the problem.

In my case I had an async void Method and I replaced with async Task ,so the test run as i expected :

    [TestMethod]
    public async  void SendTest(){}

replace with :

    [TestMethod]
    public async  Task SendTest(){}

Hey this works,

   $(function(){

   });

Complementing rijul gupta answer:

String strSDCardPath = System.getenv("SECONDARY_STORAGE");

    if ((strSDCardPath == null) || (strSDCardPath.length() == 0)) {
        strSDCardPath = System.getenv("EXTERNAL_SDCARD_STORAGE");
    }

    //If may get a full path that is not the right one, even if we don't have the SD Card there. 
    //We just need the "/mnt/extSdCard/" i.e and check if it's writable
    if(strSDCardPath != null) {
        if (strSDCardPath.contains(":")) {
            strSDCardPath = strSDCardPath.substring(0, strSDCardPath.indexOf(":"));
        }
        File externalFilePath = new File(strSDCardPath);

        if (externalFilePath.exists() && externalFilePath.canWrite()){
            //do what you need here

I have created a library matrix-slicer to manipulate with matrix items. So your problem could be solved like this:

var m = new Matrix([
    [1, 2],
    [3, 4],
]);

m.getColumn(1); // => [2, 4]

Possible it will be useful for somebody. ;-)

There is no way to get the old password back. Log into the SQL server management console as a machine or domain admin using integrated authentication, you can then change any password (including sa).

Start the SQL service again and use the new created login (recovery in my example) Go via the security panel to the properties and change the password of the SA account.

Now write down the new SA password.

I managed to fix it finally. The problem is not related to HikariCP. The problem persisted because of some complex methods in REST controllers executing multiple changes in DB through JPA repositories. For some reasons calls to these interfaces resulted in a growing number of "freezed" active connections, exhausting the pool. Either annotating these methods as @Transactional or enveloping all the logic in a single call to transactional service method seem to solve the problem.

Since Clone would return an object instance of Book, that object would first need to be cast to a Book before you can call ToList on it. The example above needs to be written as:

List<Book> books_2 = books_1.Select(book => (Book)book.Clone()).ToList();

It's simple, every time you open Jupyter Notebook and you are in your current work directory, open the Terminal in the near top right corner position where create new Python file in. The terminal in Jupyter will appear in the new tab. Type command cd <your new work directory> and enter, and then type Jupyter Notebook in that terminal, a new Jupyter Notebook will appear in the new tab with your new work directory.

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

I am showing with an example of adding random color. You can write this way

var r = Math.floor(Math.random() * 255);
var g = Math.floor(Math.random() * 255);
var b = Math.floor(Math.random() * 255);
var col = "rgb(" + r + "," + g + "," + b + ")";
parent.childNodes[1].style.color = col;

The property is expected as a string

You can also do

rake db:rollback

if you have not added any data to the tables.Then edit the migration file by adding the email column to it and then call

rake db:migrate

This will work if you have rails 3.1 onwards installed in your system.

Much simpler way of doing it is change let the change in migration file be as it is. use

$rake db:migrate:redo

This will roll back the last migration and migrate it again.

I've a sample for multiple data with their subnode 3 list , each list has attribute and child attribute:

var list1 = {
    name: "Role A",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Write",
        id: 2,
        selected: false
    }, {
        sub: "Update",
        id: 3,
        selected: false
    }],
};
var list2 = {
    name: "Role B",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Write",
        id: 2,
        selected: false
    }],
};
var list3 = {
    name: "Role B",
    name_selected: false,
    subs: [{
        sub: "Read",
        id: 1,
        selected: false
    }, {
        sub: "Update",
        id: 3,
        selected: false
    }],
};

Add these to Array :

newArr.push(list1);
newArr.push(list2);
newArr.push(list3);
$scope.itemDisplayed = newArr;

Show them in html:

<li ng-repeat="item in itemDisplayed" class="ng-scope has-pretty-child">
    <div>
        <ul>
            <input type="checkbox" class="checkall" ng-model="item.name_selected" ng-click="toggleAll(item)" />
            <span>{{item.name}}</span>
            <div>
                <li ng-repeat="sub in item.subs" class="ng-scope has-pretty-child">
                    <input type="checkbox" kv-pretty-check="" ng-model="sub.selected" ng-change="optionToggled(item,item.subs)"><span>{{sub.sub}}</span>
                </li>
            </div>
        </ul>
    </div>
</li>

And here is the solution to check them:

$scope.toggleAll = function(item) {
    var toogleStatus = !item.name_selected;
    console.log(toogleStatus);
    angular.forEach(item, function() {
        angular.forEach(item.subs, function(sub) {
            sub.selected = toogleStatus;
        });
    });
};

$scope.optionToggled = function(item, subs) {
    item.name_selected = subs.every(function(itm) {
        return itm.selected;
    })
}

I faced similar error, tried all the suggestions above, but did not resolve. what worked for me is this:

Right-click your Global.asax file and click View Markup. You will see the attribute Inherits="nadeem.MvcApplication". This means that your Global.asax file is trying to inherit from the type nadeem.MvcApplication.

Now double click your Global.asax file and see what the class name specified in your Global.asax.cs file is. It should look something like this:

namespace nadeem
{

public class MvcApplication: System.Web.HttpApplication
    {
    ....

But if it doesn't look like above, you will receive that error, The value in the Inherits attribute of your Global.asax file must match a type that is derived from System.Web.HttpApplication.

Check below link for more info:

Parser Error: Server Error in '/' Application

This is what the res.locals object is for. Setting variables directly on the request object is not supported or documented. res.locals is guaranteed to hold state over the life of a request.

res.locals

An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any). Otherwise, this property is identical to app.locals.

This property is useful for exposing request-level information such as the request path name, authenticated user, user settings, and so on.

app.use(function(req, res, next) {
    res.locals.user = req.user;  
    res.locals.authenticated = !req.user.anonymous;
    next();
});

To retrieve the variable in the next middleware:

app.use(function(req, res, next) {
    if (res.locals.authenticated) {
        console.log(res.locals.user.id);
    }
    next();
});

Or you can do like this:

your_df.to_excel( r'C:\Users\full_path\excel_name.xlsx',
                  sheet_name= 'your_sheet_name'
                )

Isn't it this simple?

var result = _(data)
            .groupBy(x => x.color)
            .map((value, key) => ({color: key, users: value}))
            .value();

array_map is a call back function, where you can play with the passed array. this should work.

$str = implode(',', array_map(function($el){ return $el['tag_id']; }, $arr));

The important thing to note here is that the mime type is not the same as the file extension. Sometimes, however, they have the same value.

https://www.iana.org/assignments/media-types/media-types.xhtml includes a list of registered Mime types, though there is nothing stopping you from making up your own, as long as you are at both the sending and the receiving end. Here is where Microsoft comes in to the picture.

Where there is a lot of confusion is the fact that operating systems have their own way of identifying file types by using the tail end of the file name, referred to as the extension. In modern operating systems, the whole name is one long string, but in more primitive operating systems, it is treated as a separate attribute.

The OS which caused the confusion is MSDOS, which had limited the extension to 3 characters. This limitation is inherited to this day in devices, such as SD cards, which still store data in the same way.

One side effect of this limitation is that some file extensions, such as .gif match their Mime Type, image/gif, while others are compromised. This includes image/jpeg whose extension is shortened to .jpg. Even in modern Windows, where the limitation is lifted, Microsoft never let the past go, and so the file extension is still the shortened version.

Given that that:

1. File Extensions are not File Types
2. Historically, some operating systems had serious file name limitations
3. Some operating systems will just go ahead and make up their own rules

The short answer is:

• Technically, there is no such thing as image/jpg, so the answer is that it is not the same as image/jpeg
• That won’t stop some operating systems and software from treating it as if it is the same

While we’re at it …

Legacy versions of Internet Explorer took the liberty of uploading jpeg files with the Mime Type of image/pjpeg, which, of course, just means more work for everybody else. They also uploaded png files as image/x-png.

Replace

@RunWith(MockitoJUnitRunner.class)

with

@RunWith(MockitoJUnitRunner.Silent.class)

or remove @RunWith(MockitoJUnitRunner.class)

or just comment out the unwanted mocking calls (shown as unauthorised stubbing).

The problem is with the way you are printing the Time data

java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());
System.out.println(sa); //this will print the milliseconds as the toString() has been written in that format

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(timestamp)); //this will print without ms

First of all, two things that we need to understand,

Client

• It makes request to a specific server

bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);

here mServiceConn is instance of ServiceConnection class(inbuilt) it is actually interface that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.

Server

• It handles the request of the client and makes replica of its own which is private to client only who send request and this raplica of server runs on different thread.

Now at client side, how to access all the methods of server?

• Server sends response with IBinder Object. So, IBinder object is our handler which accesses all the methods of Service by using (.) operator.

.

MyService myService;
public ServiceConnection myConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder binder) {
        Log.d("ServiceConnection","connected");
        myService = binder;
    }
    //binder comes from server to communicate with method's of 

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
}

Now how to call method which lies in service

myservice.serviceMethod();

Here myService is object and serviceMethod is method in service. and by this way communication is established between client and server.

What works for me is that:

• Stopped the ec2 instance
• detach the volume
• attach the volume with the old instance using the same key and was able to SSH
• mount the volume in some temp folder
• checked the file in the directory mount_point/home/ec2-user/.ssh/authorized_keys
  • Ideally, this file needs to have our key information but for me this file was empty
• copied the old instance authorized_keys file to the newly mounted volume
• unmount the device
• reattach to the original ec2 instance
• start it and let it pass the health checks

This time it works for me. But I don't know why it doesn't have my key file information at first when the instance was launched. Check this link too https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/TroubleshootingInstancesConnecting.html#TroubleshootingInstancesConnectingMindTerm

In this way we can make it use the values to the pass the information between the controller to other page with TEMP DATA

Update: you can read the more complex answer, which contains more methods and information.

There exists a couple of scripts, which can be used as simple package managers. But as far as I know, none of them allows you to upgrade packages, because it’s not an easy task on Windows since there is not possible to overwrite files in use. So you have to close all Cygwin instances first and then you can use Cygwin’s native setup.exe (which itself does the upgrade via “replace after reboot” method, when files are in use).

apt-cyg

The best one for me. Simply because it’s one of the most recent. It works correctly for both platforms - x86 and x86_64. There exists a lot of forks with some additional features. For example the kou1okada fork is one of improved versions.

Cygwin’s setup.exe

It has also command line mode. Moreover it allows you to upgrade all installed packages at once.

setup.exe-x86_64.exe -q --packages=bash,vim

Example use:

setup.exe-x86_64.exe -q --packages="bash,vim"

You can create an alias for easier use, for example:

alias cyg-get="/cygdrive/d/path/to/cygwin/setup-x86_64.exe -q -P"

Then you can for example install the Vim package with:

cyg-get vim

Just Checkout This :

Solution 1 :

In Subgrid Function You have to write following :

var selectid = $(this).jqGrid('getCell', row_id, 'id');
alert(selectid);

Where row_id is the variable which you define in subgrid as parameter. And id is the column name which you want to get value of the cell.

Solution 2 :

If You Get Jqgrid Row Id In alert Then set your primary key id as key:true In ColModels. So You will get value of your database id in alert. Like this :

{name:"id",index:"id",hidden:true, width:15,key:true, jsonmap:"id"},

A more Git based approach would be to make the changes to your local copy using cd or copy and pasting and then pushing these changes from local to remote repository.

If you try checking status of your local repo, it may show "untracked changes" which are actually the relocated files. To push these changes forcefully, you need to stage these files/directories by using

$ git add -A
#And commiting them
$ git commit -m "Relocating image demo files"
#And finally, push
$ git push -u local_repo -f HEAD:master

Hope it helps.

The following approach works for me:

<exclude name="**/dir_name_to_exclude/**" />

This will get you the row count, but will leave the data reader at the end.

dataReader.Cast<object>().Count();

There could be a couple of things going wrong in this situation (assuming that you had code after your example and didn't just leave your code unbracketed).

First off, if you are running your entire project and not just the current file, make sure your project is the main project and the main class of the project is set to the correct file.

Otherwise, I have seen classmates with their code being fine but they still had this same problem. Sometimes, in Netbeans, a simple fix is to:

1. Copy your current code (or back it up in a different location)
2. Delete your current file
3. Create a new main class in your project (you can name it the old one)
4. Paste your code back in

If this doesn't work then try to clear the Netbeans cache, and if all else fails, then just do a clean un-installation and re-installation of Netbeans.

One small addition, all above are the actual reasons why your scroll view might not be scrolling but sometimes mindlessly this could be the reason specially when scrollview is added through code and not IB, you might have added your subviews to the parent view and not to the scrollview this causes the subview to not scroll

and do keep the content size set and bigger than parent view frame (duhh!!)

This is a feature of C# 4.0, but was not possible without using function overload prior to that version.

One common way is to add the image to a QLabel widget using QLabel::setPixmap(), and then display the QLabel as you would any other widget. Example:

#include <QtGui>

int main(int argc, char *argv[])
{
  QApplication app(argc, argv);
  QPixmap pm("your-image.jpg");
  QLabel lbl;
  lbl.setPixmap(pm);
  lbl.show();
  return app.exec();
}

This works:

assertThat(list,IsEmptyCollection.empty())

I like

 Get-WmiObject Win32_computersystem | format-custom *

That seems to expand everything.

There's also a show-object command in the PowerShellCookbook module that does it in a GUI. Jeffrey Snover, the PowerShell creator, uses it in his unplugged videos (recommended).

Although most often I use

Get-WmiObject Win32_computersystem | fl *

It avoids the .format.ps1xml file that defines a table or list view for the object type, if there are any. The format file may even define column headers that don't match any property names.

I have formatted the nice solution provided by JeremyP above into a more generic reusable function below:

///Return an ARRAY containing the exploded chunk of strings
+(NSArray*)explodeString:(NSString*)stringToBeExploded WithDelimiter:(NSString*)delimiter
{
    return [stringToBeExploded componentsSeparatedByString: delimiter];
}

Have you considered using something like Quartz Scheduler? This library has a mechanism for scheduling tasks to run at a set period of time every day using a cron like expression (take a look at CronScheduleBuilder).

Some example code (not tested):

public class GetDatabaseJob implements InterruptableJob
{
    public void execute(JobExecutionContext arg0) throws JobExecutionException
    {
        getFromDatabase();
    }
}

public class Example
{
    public static void main(String[] args)
    {
        JobDetails job = JobBuilder.newJob(GetDatabaseJob.class);

        // Schedule to run at 5 AM every day
        ScheduleBuilder scheduleBuilder = 
                CronScheduleBuilder.cronSchedule("0 0 5 * * ?");
        Trigger trigger = TriggerBuilder.newTrigger().
                withSchedule(scheduleBuilder).build();

        Scheduler scheduler = StdSchedulerFactory.getDefaultScheduler();
        scheduler.scheduleJob(job, trigger);

        scheduler.start();
    }
}

There's a bit more work upfront, and you may need to rewrite your job execution code, but it should give you more control over how you want you job to run. Also it would be easier to change the schedule should you need to.

try this:

key=key.replace(/ /g,"_");

that'll do a global find/replace

With zsh you can do this:

% cat infile 
tar
more than one word
gz
java
gz
java
tar
class
class
zsh-5.0.0[t]% print -l "${(fu)$(<infile)}"
tar
more than one word
gz

Or you can use AWK:

% awk '!_[$0]++' infile    
tar
more than one word

Given a data setup like this:

The formula in cell D2 and copied down is:

=INDEX($B$2:$B$28,MATCH(1,INDEX(($A$2:$A$28=LARGE($A$2:$A$28,ROWS(D$1:D1)))*(COUNTIF(D$1:D1,$B$2:$B$28)=0),),0))

This formula will work even if there are tied OPS scores among players.

No, there is no built-in support for number formatting, but googling will turn up loads of code snippets that will do this for you.

EDIT: I missed the last sentence of your post. Try http://code.google.com/p/jquery-utils/wiki/StringFormat for a jQuery solution.

Invisible: The widget takes physical space on the screen but not visible to user.

Gone: The widget doesn't take any physical space and is completely gone.

Invisible example

Visibility(
  child: Text("Invisible"),
  maintainSize: true, 
  maintainAnimation: true,
  maintainState: true,
  visible: false, 
),

Gone example

Visibility(
  child: Text("Gone"),
  visible: false,
),

Alternatively, you can use if condition for both invisible and gone.

Column(
  children: <Widget>[
    if (show) Text("This can be visible/not depending on condition"),
    Text("This is always visible"),
  ],
) 

Method 1 :

var stringValue = "true";
var boolValue = (/true/i).test(stringValue) //returns true

Method 2 :

var stringValue = "true";
var boolValue = (stringValue =="true");   //returns true

Method 3 :

var stringValue = "true";
var boolValue = JSON.parse(stringValue);   //returns true

Method 4 :

var stringValue = "true";
var boolValue = stringValue.toLowerCase() == 'true'; //returns true

Method 5 :

var stringValue = "true";
var boolValue = getBoolean(stringValue); //returns true
function getBoolean(value){
   switch(value){
        case true:
        case "true":
        case 1:
        case "1":
        case "on":
        case "yes":
            return true;
        default: 
            return false;
    }
}

It's possible to remove the workspace in Eclipse without much complications. The options are available under Preferences->General->Startup and Shutdown->Workspaces.

Note that this does not actually delete the files from the system, it simply removes it from the list of suggested workspaces. It changes the org.eclipse.ui.ide.prefs file in Jon's answer from within Eclipse.

This limitation, which was only due to historical, code legacy reasons, has been lifted in recent versions of MySQL:

Changes in MySQL 5.6.5 (2012-04-10, Milestone 8)

Previously, at most one TIMESTAMP column per table could be automatically initialized or updated to the current date and time. This restriction has been lifted. Any TIMESTAMP column definition can have any combination of DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP clauses. In addition, these clauses now can be used with DATETIME column definitions. For more information, see Automatic Initialization and Updating for TIMESTAMP and DATETIME.

works

char mystring[101] = "My sample string";
const char * constcharp = mystring; // (1)
char const * charconstp = mystring; // (2) the same as (1)
char * const charpconst = mystring; // (3)

constcharp++; // ok
charconstp++; // ok
charpconst++; // compile error

constcharp[3] = '\0'; // compile error
charconstp[3] = '\0'; // compile error
charpconst[3] = '\0'; // ok

// String literals
char * lcharp = "My string literal";
const char * lconstcharp = "My string literal";

lcharp[0] = 'X';      // Segmentation fault (crash) during run-time
lconstcharp[0] = 'X'; // compile error

// *not* a string literal
const char astr[101] = "My mutable string";
astr[0] = 'X';          // compile error
((char*)astr)[0] = 'X'; // ok

With Linq

var newList = GlobalStrings.Append(localStrings)

I rewrote David's answer using the with statement, it allows you do do this:

with timeout(seconds=3):
    time.sleep(4)

Which will raise a TimeoutError.

The code is still using signal and thus UNIX only:

import signal

class timeout:
    def __init__(self, seconds=1, error_message='Timeout'):
        self.seconds = seconds
        self.error_message = error_message
    def handle_timeout(self, signum, frame):
        raise TimeoutError(self.error_message)
    def __enter__(self):
        signal.signal(signal.SIGALRM, self.handle_timeout)
        signal.alarm(self.seconds)
    def __exit__(self, type, value, traceback):
        signal.alarm(0)

One way is to simply destroy the listener once you are done with it.

var removeListener = $scope.$on('navBarRight-ready', function () {
        $rootScope.$broadcast('workerProfile-display', $scope.worker)
        removeListener(); //destroy the listener
    })

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

Add a linefeed ("\n") to the output:

<textarea>Hello


Bybye</textarea>

Will have a newline in it.

Stole this from here. I found it very useful!

DECLARE @DB_USers TABLE

I might also look into adding explicit samples for each controller/action, as well covered here:

i.e. config.SetActualResponseType(typeof(SomeType), "Values", "Get");

<> is used to indicate generics in Java.

T is a type parameter in this example. And no: instantiating is one of the few things that you can't do with T.

Apart from the tutorial linked above Angelika Langers Generics FAQ is a great resource on the topic.

The difference is that any composition is an aggregation and not vice versa.

Let's set the terms. The Aggregation is a metaterm in the UML standard, and means BOTH composition and shared aggregation, simply named shared. Too often it is named incorrectly "aggregation". It is BAD, for composition is an aggregation, too. As I understand, you mean "shared".

Further from UML standard:

composite - Indicates that the property is aggregated compositely, i.e., the composite object has responsibility for the existence and storage of the composed objects (parts).

So, University to cathedras association is a composition, because cathedra doesn't exist out of University (IMHO)

Precise semantics of shared aggregation varies by application area and modeler.

I.e., all other associations can be drawn as shared aggregations, if you are only following to some principles of yours or of somebody else. Also look here.

Summary this Javascript:

• The value of this is determined by how the function is invoked not, where it was created!
• Usually the value of this is determined by the Object which is left of the dot. (window in global space)
• In event listeners the value of this refers to the DOM element on which the event was called.
• When in function is called with the new keyword the value of this refers to the newly created object
• You can manipulate the value of this with the functions: call, apply, bind

Example:

let object = {_x000D_
  prop1: function () {console.log(this);}_x000D_
}_x000D_
_x000D_
object.prop1();   // object is left of the dot, thus this is object_x000D_
_x000D_
const myFunction = object.prop1 // We store the function in the variable myFunction_x000D_
_x000D_
myFunction(); // Here we are in the global space_x000D_
              // myFunction is a property on the global object_x000D_
              // Therefore it logs the window object_x000D_
              _x000D_
             

Example event listeners:

document.querySelector('.foo').addEventListener('click', function () {_x000D_
  console.log(this);   // This refers to the DOM element the eventListener was invoked from_x000D_
})_x000D_
_x000D_
_x000D_
document.querySelector('.foo').addEventListener('click', () => {_x000D_
  console.log(this);  // Tip, es6 arrow function don't have their own binding to the this v_x000D_
})                    // Therefore this will log the global object

.foo:hover {_x000D_
  color: red;_x000D_
  cursor: pointer;_x000D_
}

<div class="foo">click me</div>

Example constructor:

function Person (name) {_x000D_
  this.name = name;_x000D_
}_x000D_
_x000D_
const me = new Person('Willem');_x000D_
// When using the new keyword the this in the constructor function will refer to the newly created object_x000D_
_x000D_
console.log(me.name); _x000D_
// Therefore, the name property was placed on the object created with new keyword.

Set the auto increment field to NULL or 0 if you want it to be auto magically assigned...

It's hard for us to bind a specific USB device to a docker container which is also specific. As you can see, the recommended way to achieve is:

docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb ubuntu bash

It will bind all the devices to this container. It's unsafe. Every containers were granted to operate all of them.

Another way is binding devices by devpath. It may looks like:

docker run -t -i --privileged -v /dev/bus/usb/001/002:/dev/bus/usb/001/002 ubuntu bash

or --device (better, no privileged):

docker run -t -i --device /dev/bus/usb/001/002 ubuntu bash

Much safer. But actually it is hard to know what the devpath of a specific device is.

I have wrote this repo to solve this problem.

https://github.com/williamfzc/usb2container

After deploying this server, you can easily get all the connected devices' information via HTTP request:

curl 127.0.0.1:9410/api/device

and get:

{
    "/devices/pci0000:00/0000:00:14.0/usb1/1-13": {
        "ACTION": "add",
        "DEVPATH": "/devices/pci0000:00/0000:00:14.0/usb1/1-13",
        "DEVTYPE": "usb_device",
        "DRIVER": "usb",
        "ID_BUS": "usb",
        "ID_FOR_SEAT": "xxxxx",
        "ID_MODEL": "xxxxx",
        "ID_MODEL_ID": "xxxxx",
        "ID_PATH": "xxxxx",
        "ID_PATH_TAG": "xxxxx",
        "ID_REVISION": "xxxxx",
        "ID_SERIAL": "xxxxx",
        "ID_SERIAL_SHORT": "xxxxx",
        "ID_USB_INTERFACES": "xxxxx",
        "ID_VENDOR": "xxxxx",
        "ID_VENDOR_ENC": "xxxxx",
        "ID_VENDOR_FROM_DATABASE": "",
        "ID_VENDOR_ID": "xxxxx",
        "INTERFACE": "",
        "MAJOR": "189",
        "MINOR": "119",
        "MODALIAS": "",
        "PRODUCT": "xxxxx",
        "SEQNUM": "xxxxx",
        "SUBSYSTEM": "usb",
        "TAGS": "",
        "TYPE": "0/0/0",
        "USEC_INITIALIZED": "xxxxx",
        "adb_user": "",
        "_empty": false,
        "DEVNAME": "/dev/bus/usb/001/120",
        "BUSNUM": "001",
        "DEVNUM": "120",
        "ID_MODEL_ENC": "xxxxx"
    },
    ...
}

and bind them to your containers. For example, you can see the DEVNAME of this device is /dev/bus/usb/001/120:

docker run -t -i --device /dev/bus/usb/001/120 ubuntu bash

Maybe it will help.

In SQL Plus:

I usually use git add --all to remove files / folders from remote repositories

rm -r folder_name
git add --all
git commit -m "some comment"
git push origin master

master can be replaced by any other branch of the repository.

you can try with :

return 0;

that work in case of stop process.

It can be caused by:

1. Invalid HTML syntax (some tag is not closed or similar error)
2. Duplicate IDs - there are two HTML DOM elements with the same ID
3. Maybe element you are trying to get by ID is created dynamically (loaded by ajax or created by script)?

Please, post your code.

If you want the units h, min and sec for a duration you can use this:

public static String convertSeconds(int seconds) {
    int h = seconds/ 3600;
    int m = (seconds % 3600) / 60;
    int s = seconds % 60;
    String sh = (h > 0 ? String.valueOf(h) + " " + "h" : "");
    String sm = (m < 10 && m > 0 && h > 0 ? "0" : "") + (m > 0 ? (h > 0 && s == 0 ? String.valueOf(m) : String.valueOf(m) + " " + "min") : "");
    String ss = (s == 0 && (h > 0 || m > 0) ? "" : (s < 10 && (h > 0 || m > 0) ? "0" : "") + String.valueOf(s) + " " + "sec");
    return sh + (h > 0 ? " " : "") + sm + (m > 0 ? " " : "") + ss;
}

int seconds = 3661;
String duration = convertSeconds(seconds);

That's a lot of conditional operators. The method will return those strings:

0    -> 0 sec
5    -> 5 sec
60   -> 1 min
65   -> 1 min 05 sec
3600 -> 1 h
3601 -> 1 h 01 sec
3660 -> 1 h 01
3661 -> 1 h 01 min 01 sec
108000 -> 30 h

Well... I would like you to understand more specific areas of space. \t is actually assorted as a horizontal space, not a vertical space. (test out inserting \t in Notepad)

If you use Java, simply use \v. See the reference below.

\h - A horizontal whitespace character:

[\t\xA0\u1680\u180e\u2000-\u200a\u202f\u205f\u3000]

\v - A vertical whitespace character:

[\n\x0B\f\r\x85\u2028\u2029]

But I am aware that you use .NET. So my answer to replacing every vertical space is..

string replacement = Regex.Replace(s, @"[\n\u000B\u000C\r\u0085\u2028\u2029]", "");

Not core Java, and not generic-ified, but the popular Jakarta commons collections library has some useful abstractions for this sort of task. Specifically, have a look at the collect methods on

CollectionUtils

Something to consider if you are already using commons collections in your project.

if you are using any mobile suit like mobogenie or something that might also will make this issue. try killing that too from the task manager.

Note : i faced the same issue, tried the above solution. That didn't work, finally found out this solution.May useful for someone else!..

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

I think, the best and easy way for you, to put value inside quotes is:

JSON.stringify(variable or value)

For simplicity's sake: newList = list(set(oldList))

But there are better options out there if you'd like to get speed/ordering/optimization instead: http://www.peterbe.com/plog/uniqifiers-benchmark

Object Oriented Approach :

/**
 * Returns a directory size
 *
 * @param string $directory
 *
 * @return int $size directory size in bytes
 *
 */
function dir_size($directory)
{
    $size = 0;
    foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file)
    {
        $size += $file->getSize();
    }
    return $size;
}

Fast and Furious Approach :

function dir_size2($dir)
{
    $line = exec('du -sh ' . $dir);
    $line = trim(str_replace($dir, '', $line));
    return $line;
}

Foo(x_ptr);
Foo(&x);

If you want a pointer for another type of object, it's much the same:

void Foo(Object *o);

But, you may prefer to use references. They are somewhat less confusing than pointers:

// pass a reference
void Foo(int &x)
{
  x = 2;
}

//pass a pointer
void Foo_p(int *p)
{
   *x = 9;
}

// pass by value
void Bar(int x)
{
   x = 7;
}
int x = 4;
Foo(x);  // x now equals 2.
Foo_p(&x); // x now equals 9.
Bar(x);  // x still equals 9.

With references, you still get to change the x that was passed to the function (as you would with a pointer), but you don't have to worry about dereferencing or address of operations.

As recommended by others, check out the C++FAQLite. It's an excellent resource for this.

Edit 3 response:

bar = &foo means: Make bar point to foo in memory

Yes.

*bar = foo means Change the value that bar points to to equal whatever foo equals

Yes.

If I have a second pointer (int *oof), then:

bar = oof means: bar points to the oof pointer

bar will point to whatever oof points to. They will both point to the same thing.

bar = *oof means: bar points to the value that oof points to, but not to the oof pointer itself

No. You can't do this (assuming bar is of type int *) You can make pointer pointers. (int **), but let's not get into that... You cannot assign a pointer to an int (well, you can, but that's a detail that isn't in line with the discussion).

*bar = *oof means: change the value that bar points to to the value that oof points to

Yes.

&bar = &oof means: change the memory address that bar points to be the same as the memory address that oof points to

No. You can't do this because the address of operator returns an rvalue. Basically, that means you can't assign something to it.

Javascript has a built in JSON parse for strings, which I think is what you have:

var myObject = JSON.parse("my json string");

to use this with your example would be:

var jsonData = JSON.parse(myMessage);
for (var i = 0; i < jsonData.counters.length; i++) {
    var counter = jsonData.counters[i];
    console.log(counter.counter_name);
}

Here is a working example

EDIT: There is a mistake in your use of for loop (I missed this on my first read, credit to @Evert for the spot). using a for-in loop will set the var to be the property name of the current loop, not the actual data. See my updated loop above for correct usage

IMPORTANT: the JSON.parse method wont work in old old browsers - so if you plan to make your website available through some sort of time bending internet connection, this could be a problem! If you really are interested though, here is a support chart (which ticks all my boxes).

A slight improvement to Bizzard's excellent answer. Supports width-offset and/or height-offset on the element, to determine how much will be subtracted from the width/height, and prevents negative dimensions.

 <div resize height-offset="260" width-offset="100">

directive:

app.directive('resize', ['$window', function ($window) {
    return function (scope, element) {
        var w = angular.element($window);
        var heightOffset = parseInt(element.attr('height-offset'));
        var widthOffset = parseInt(element.attr('width-offset'));
        var changeHeight = function () {
            if (!isNaN(heightOffset) && w.height() - heightOffset > 0)
                element.css('height', (w.height() - heightOffset) + 'px');
            if (!isNaN(widthOffset) && w.width() - widthOffset > 0)
                element.css('width', (w.width() - widthOffset) + 'px');
        };
        w.bind('resize', function () {
            changeHeight();
        });
        changeHeight();
    }
}]);

Edit This is actually a silly way of doing it in modern browsers. CSS3 has calc, which allows the calculation to be specified in CSS, like this:

#myDiv {
 width: calc(100% - 200px);
 height: calc(100% - 120px);
}

http://caniuse.com/#search=calc

variable=10
f=open("fileName.txt","w+") # file name and mode
for x in range(0,10):
    f.writelines('your text')
    f.writelines('if you want to add variable data'+str(variable))
    # to add data you only add String data so you want to type cast variable  
    f.writelines("\n")

Introduced in numpy 1.8:

numpy.full

Return a new array of given shape and type, filled with fill_value.

Examples:

>>> import numpy as np
>>> np.full((2, 2), np.inf)
array([[ inf,  inf],
       [ inf,  inf]])
>>> np.full((2, 2), 10)
array([[10, 10],
       [10, 10]])

Here is a "Tab" text (copy and paste): " "

It may appear different or not a full tab because of the answer limitations of this site.

solution is based on these things:

• you need to use your own class that extends Toolbar (support.v7.widget.toolbar)
• you need to override one method Toolbar#addView

what does it do:

when first time toolbar is executing #setTitle, it creates AppCompatTextView and uses it to display title text.

when the AppCompatTextView is created, toolbar (as ViewGroup), adds it into it's own hierarchy with #addView method.

also, while trying to find solution i noticed that the textview has layout width set to "wrap_content", so i decided to make it "match_parent" and assign textalignment to "center".

MyToolbar.kt, skipping unrelated stuff (constructors/imports):

class MyToolbar : Toolbar {

  override fun addView(child: View, params: ViewGroup.LayoutParams) {
    if (child is TextView) {
        params.width = ViewGroup.LayoutParams.MATCH_PARENT
        child.textAlignment= View.TEXT_ALIGNMENT_CENTER
    }
    super.addView(child, params)
  }
}

possible "side effects" - this will apply to "subtitle" too

Stash is just a convenience method. Since branches are so cheap and easy to manage in git, I personally almost always prefer creating a new temporary branch than stashing, but it's a matter of taste mostly.

The one place I do like stashing is if I discover I forgot something in my last commit and have already started working on the next one in the same branch:

# Assume the latest commit was already done
# start working on the next patch, and discovered I was missing something

# stash away the current mess I made
git stash save

# some changes in the working dir

# and now add them to the last commit:
git add -u
git commit --amend

# back to work!
git stash pop

I suspect something is not right when you are saving to the db. Do i understand your steps as:

1. populate and bind
2. user selects and item, hit and save.. then you save in the db
3. now if you select another item it won't select?

got more code, especially when saving? where in your code are initializing and populating the bindinglist

1. Find Debug/Release in CONFIG

Get the current (debug | release).

specified_configs=$$find(CONFIG, "\b(debug|release)\b")
build_subdir=$$last(specified_configs)

(May be multiple, so keep only last specified in the build):

2. Set DESTDIR

Use it has the build subdir name

DESTDIR = $$PWD/build/$$build_subdir

Have you tried using the DataTable.Select(filterExpression, sortExpression) method?

If you made a virtual env, then deleted that python installation, you'll get the same error. Just rm -r your venv folder, then recreate it with a valid python location and do pip install -r requirements.txt and you'll be all set (assuming you got your requirements.txt right).

You can loop through a hash map like this

<%
ArrayList list = new ArrayList();
TreeMap itemList=new TreeMap();
itemList.put("test", "test");
list.add(itemList);
pageContext.setAttribute("itemList", list);                            
%>

  <c:forEach items="${itemList}" var="itemrow">
   <input  type="text"  value="<c:out value='${itemrow.test}'/>"/>
  </c:forEach>               

For more JSTL functionality look here

The complete way would be:

bool b1;
bool? b2 = ???;
if (b2.HasValue)
   b1 = b2.Value;

Or you can test for specific values using

bool b3 = (b2 == true); // b2 is true, not false or null

I think that access() function, which is found in unistd.h is a good choice for Linux (you can use stat too).

You can Use it like this:

#include <stdio.h>
#include <stdlib.h>
#include<unistd.h>

void fileCheck(const char *fileName);

int main (void) {
    char *fileName = "/etc/sudoers";

    fileCheck(fileName);
    return 0;
}

void fileCheck(const char *fileName){

    if(!access(fileName, F_OK )){
        printf("The File %s\t was Found\n",fileName);
    }else{
        printf("The File %s\t not Found\n",fileName);
    }

    if(!access(fileName, R_OK )){
        printf("The File %s\t can be read\n",fileName);
    }else{
        printf("The File %s\t cannot be read\n",fileName);
    }

    if(!access( fileName, W_OK )){
        printf("The File %s\t it can be Edited\n",fileName);
    }else{
        printf("The File %s\t it cannot be Edited\n",fileName);
    }

    if(!access( fileName, X_OK )){
        printf("The File %s\t is an Executable\n",fileName);
    }else{
        printf("The File %s\t is not an Executable\n",fileName);
    }
}

And you get the following Output:

The File /etc/sudoers    was Found
The File /etc/sudoers    cannot be read
The File /etc/sudoers    it cannot be Edited
The File /etc/sudoers    is not an Executable

With Java 8+ you can use Stream API:

boolean areAllDistinct(List<Block> blocksList) {
    return blocksList.stream().map(Block::getNum).distinct().count() == blockList.size();
}

There is no difference.

Reason:

Books on-line says "COUNT ( { [ [ ALL | DISTINCT ] expression ] | * } )"

"1" is a non-null expression: so it's the same as COUNT(*). The optimizer recognizes it for what it is: trivial.

The same as EXISTS (SELECT * ... or EXISTS (SELECT 1 ...

Example:

SELECT COUNT(1) FROM dbo.tab800krows
SELECT COUNT(1),FKID FROM dbo.tab800krows GROUP BY FKID

SELECT COUNT(*) FROM dbo.tab800krows
SELECT COUNT(*),FKID FROM dbo.tab800krows GROUP BY FKID

Same IO, same plan, the works

Edit, Aug 2011

Similar question on DBA.SE.

Edit, Dec 2011

COUNT(*) is mentioned specifically in ANSI-92 (look for "Scalar expressions 125")

Case:

a) If COUNT(*) is specified, then the result is the cardinality of T.

That is, the ANSI standard recognizes it as bleeding obvious what you mean. COUNT(1) has been optimized out by RDBMS vendors because of this superstition. Otherwise it would be evaluated as per ANSI

b) Otherwise, let TX be the single-column table that is the result of applying the <value expression> to each row of T and eliminating null values. If one or more null values are eliminated, then a completion condition is raised: warning-

Instead of

Image.open(picture.jpg)
Img.show

You should have

from PIL import Image

#...

img = Image.open('picture.jpg')

You should probably also think about an other system to show your messages, because this way it will be a lot of manual work. Look into string substitution (using %s or .format()).

On Linux it's Monospace 10 pt. (the exact monospace font used may vary on different Linux distributions or versions), on Windows it's Consolas 10 pt., and on OS X it's Menlo Regular 12 pt.

^{(The color scheme is Neon, the syntax highlighting is from PackageDev, and the font is Liberation Mono}

This information is found in the Packages/Default directory (where Packages is the directory opened by the Preferences ? Browse Packages... menu option), in the Preferences (OS).sublime-settings file where OS is one of Windows, Linux, or OSX.

You should only customize the font (or any other setting) in Packages/User/Preferences.sublime-settings, opened by Preferences ? Settings—User, as Settings—Default is over-written on upgrade, and also serves as a backup in case you really screw something up in your user settings. This is the case for both the main Sublime settings as well as those for extra packages/plugins.

I have a similar problem importing those libs. I am using Anaconda Navigator 1.8.2 with Spyder 3.2.8.

My code is the following:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from tensorflow.python.keras.models import Sequential
from tensorflow.python.keras.layers import InputLayer, Input
from tensorflow.python.keras.layers import Reshape, MaxPooling2D
from tensorflow.python.keras.layers import Conv2D, Dense, Flatten

I get the following error:

from tensorflow.python.keras.models import Sequential

ModuleNotFoundError: No module named 'tensorflow.python.keras'

I solve this erasing tensorflow.python

With this code I solve the error:

import matplotlib.pyplot as plt
import tensorflow as tf
import numpy as np
import math

#from tf.keras.models import Sequential  # This does not work!
from keras.models import Sequential
from keras.layers import InputLayer, Input
from keras.layers import Reshape, MaxPooling2D
from keras.layers import Conv2D, Dense, Flatten

Try this:

  $(document).on('click','#save',function(e) {
  var data = $("#form-search").serialize();
  $.ajax({
         data: data,
         type: "post",
         url: "insertmail.php",
         success: function(data){
              alert("Data Save: " + data);
         }
});
 });

and in insertmail.php:

<?php 
if(isset($_REQUEST))
{
        mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);

$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
}
?>

Don't use mysql_ it's deprecated.

another method:

Actually if your problem is null value inserted into the database then try this and here no need of ajax.

<?php
if($_POST['email']!="")
{
    mysql_connect("localhost","root","");
    mysql_select_db("eciticket_db");
    error_reporting(E_ALL && ~E_NOTICE);
    $email=$_POST['email'];
    $sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
    $result=mysql_query($sql);
    if($result){
    //echo "You have been successfully subscribed.";
              setcookie("msg","You have been successfully subscribed.",time()+5,"/");
              header("location:yourphppage.php");
    }
     if(!$sql)
    die(mysql_error());
    mysql_close();
}
?>
    <?php if(isset($_COOKIE['msg'])){?>
       <span><?php echo $_COOKIE['msg'];setcookie("msg","",time()-5,"/");?></span> 
    <?php }?>

    <input type="submit" value="subscribe" class="submit"/>
</form>

Number without round

$double = '21.188624';
echo intval($double) . '.' . substr(end(explode('.', $double)), 0, 2);

You need interfaces in Java since it is statically typed and the contract between classes should be known during compilation. In JavaScript it is different. JavaScript is dynamically typed; it means that when you get the object you can just check if it has a specific method and call it.

This will do the trick. Note the use of display() instead of print.

with pd.option_context('display.max_rows', 5, 'display.max_columns', None): 
    display(my_df)

EDIT:

The use of display is required because pd.option_context settings only apply to display and not to print.

You can try Alasql JavaScript library which can work together with XLSX.js library for easy export of Angular.js data. This is an example of controller with exportData() function:

function myCtrl($scope) {
  $scope.exportData = function () {
    alasql('SELECT * INTO XLSX("john.xlsx",{headers:true}) FROM ?',[$scope.items]);
  };

  $scope.items = [{
    name: "John Smith",
    email: "[email protected]",
    dob: "1985-10-10"
  }, {
    name: "Jane Smith",
    email: "[email protected]",
    dob: "1988-12-22"
  }];
}

See full HTML and JavaScript code for this example in jsFiddle.

UPDATED Another example with coloring cells.

Also you need to include two libraries:

• alasql.min.js
• xlsx.core.min.js

Try changing your headers to this:

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1" . "\r\n";
$headers .= "From: [email protected]" . "\r\n" .
"Reply-To: [email protected]" . "\r\n" .
"X-Mailer: PHP/" . phpversion();

For a few reasons.

• One of which is the need of a Reply-To and,

• The use of apostrophes instead of double-quotes. Those two things in my experience with forms, is usually what triggers a message ending up in the Spam box.

You could also try changing the $from to:

$from = "[email protected]";

EDIT:

See these links I found on the subject https://stackoverflow.com/a/9988544/1415724 and https://stackoverflow.com/a/16717647/1415724 and https://stackoverflow.com/a/9899837/1415724

This is not a spring boot tutorial. It's the updated answer to a question on how to run a Maven build within a Docker container.

Question originally posted 4 years ago.

1. Generate an application

Use the spring initializer to generate a demo app

https://start.spring.io/

Extract the zip archive locally

2. Create a Dockerfile

#
# Build stage
#
FROM maven:3.6.0-jdk-11-slim AS build
COPY src /home/app/src
COPY pom.xml /home/app
RUN mvn -f /home/app/pom.xml clean package

#
# Package stage
#
FROM openjdk:11-jre-slim
COPY --from=build /home/app/target/demo-0.0.1-SNAPSHOT.jar /usr/local/lib/demo.jar
EXPOSE 8080
ENTRYPOINT ["java","-jar","/usr/local/lib/demo.jar"]

Note

• This example uses a multi-stage build. The first stage is used to build the code. The second stage only contains the built jar and a JRE to run it (note how jar is copied between stages).

3. Build the image

docker build -t demo .

4. Run the image

$ docker run --rm -it demo:latest

Misc

Read the Docker hub documentation on how the Maven build can be optimized to use a local repository to cache jars.

• https://hub.docker.com/_/maven

  ---

Update (2019-02-07)

This question is now 4 years old and in that time it's fair to say building application using Docker has undergone significant change.

Option 1: Multi-stage build

This new style enables you to create more light-weight images that don't encapsulate your build tools and source code.

The example here again uses the official maven base image to run first stage of the build using a desired version of Maven. The second part of the file defines how the built jar is assembled into the final output image.

FROM maven:3.5-jdk-8 AS build  
COPY src /usr/src/app/src  
COPY pom.xml /usr/src/app  
RUN mvn -f /usr/src/app/pom.xml clean package

FROM gcr.io/distroless/java  
COPY --from=build /usr/src/app/target/helloworld-1.0.0-SNAPSHOT.jar /usr/app/helloworld-1.0.0-SNAPSHOT.jar  
EXPOSE 8080  
ENTRYPOINT ["java","-jar","/usr/app/helloworld-1.0.0-SNAPSHOT.jar"]  

Note:

• I'm using Google's distroless base image, which strives to provide just enough run-time for a java app.

Option 2: Jib

I haven't used this approach but seems worthy of investigation as it enables you to build images without having to create nasty things like Dockerfiles :-)

https://github.com/GoogleContainerTools/jib

The project has a Maven plugin which integrates the packaging of your code directly into your Maven workflow.

Original answer (Included for completeness, but written ages ago)

Try using the new official images, there's one for Maven

https://registry.hub.docker.com/_/maven/

The image can be used to run Maven at build time to create a compiled application or, as in the following examples, to run a Maven build within a container.

Example 1 - Maven running within a container

The following command runs your Maven build inside a container:

docker run -it --rm \
       -v "$(pwd)":/opt/maven \
       -w /opt/maven \
       maven:3.2-jdk-7 \
       mvn clean install

Notes:

• The neat thing about this approach is that all software is installed and running within the container. Only need docker on the host machine.
• See Dockerfile for this version

Example 2 - Use Nexus to cache files

Run the Nexus container

docker run -d -p 8081:8081 --name nexus sonatype/nexus

Create a "settings.xml" file:

<settings>
  <mirrors>
    <mirror>
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://nexus:8081/content/groups/public/</url>
    </mirror>
  </mirrors>
</settings>

Now run Maven linking to the nexus container, so that dependencies will be cached

docker run -it --rm \
       -v "$(pwd)":/opt/maven \
       -w /opt/maven \
       --link nexus:nexus \
       maven:3.2-jdk-7 \
       mvn -s settings.xml clean install

Notes:

• An advantage of running Nexus in the background is that other 3rd party repositories can be managed via the admin URL transparently to the Maven builds running in local containers.

I have a very simple solution for this problem. You don't need to use the console.

TLDR: Create repo, move files to existing projects folder, SourceTree will ask you where his files are, locate the files. Done, your repo is in another folder.

Long answer:

1. Create your new repository on Bitbucket
2. Click "Clone in SourceTree"
3. Let the program put your new repo where it wants, in my case SourceTree created a new folder in My Documents.
4. Locate in windows explorer your new repository folder.
5. Cut the .hg and README (or anything else you find in that folder)
6. Paste it in the location where is your existing project
7. Return to SourceTree and it will say "Error encountered...", just click OK
8. On the left side you will have your repository but with red message: Repository Moved or Deleted. Click on that.
9. Now you will see Repository Missing popup. Click on Change Folder and locate your existing project folder where you have moved the files mentoned earlier.
10. Thats it!

Tips: Clone in SourceTree option is not available right after you create new repository so you first have to click on Create Readme File for that option to become available.

Try this:

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let indexPath = tableView.indexPathForSelectedRow() //optional, to get from any UIButton for example

    let currentCell = tableView.cellForRowAtIndexPath(indexPath) as UITableViewCell

    print(currentCell.textLabel!.text)

Just type the code and save it in .cpp format. then try "gcc filename.cpp" . This will create the object file. then try "./a.out" (This is the default object file name). If you want to know about gcc you can always try "man gcc"

You just have to check your Xml file. If there is an error then you can't resolve this error. Just solve error in xml then try.

Yes, 4,2 means "4 digits total, 2 of which are after the decimal place". That translates to a number in the format of 00.00. Beyond that, you'll have to show us your SQL query. PHP won't translate 3.80 into 99.99 without good reason. Perhaps you've misaligned your fields/values in the query and are trying to insert a larger number that belongs in another field.
