I faced the same problem. Found the fix here.

Basically just install this.

shasum output:

3e0de8af516c15547602977db939d8c2e44fcc0b  visualcppbuildtools_full.exe

md5sum output:

MD5 (visualcppbuildtools_full.exe) = 8d4afd3b226babecaa4effb10d69eb2e

Run your pip installation command again. If everything works fine, its good. Or you might face the following error like me:

Finished generating code
    LINK : fatal error LNK1158: cannot run 'rc.exe'
    error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158

Found the fix for the above problem here: Visual Studio can't build due to rc.exe

That basically says

Add this to your PATH environment variables:

C:\Program Files (x86)\Windows Kits\8.1\bin\x86

Copy these files:

rc.exe
rcdll.dll

From

C:\Program Files (x86)\Windows Kits\8.1\bin\x86

To

C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin

It works like a charm

The simple answer:

• doing a MOV RBX, 3 and MUL RBX is expensive; just ADD RBX, RBX twice

• ADD 1 is probably faster than INC here

• MOV 2 and DIV is very expensive; just shift right

• 64-bit code is usually noticeably slower than 32-bit code and the alignment issues are more complicated; with small programs like this you have to pack them so you are doing parallel computation to have any chance of being faster than 32-bit code

If you generate the assembly listing for your C++ program, you can see how it differs from your assembly.

I recently had this issue and all above solutions didn't work for me.

The reason why it works on your simulator but not real devices is probably related to your Development Certificate.

So I revoked my certificate on Apple Developer Portal and request a new one on my computer. Here are the steps:

1. Goto Apple Developer Portal and revoke your old (not working) development certificate.
2. Add iOS App Development Certificate
3. Follow the step on from Apple
4. Download the newly generated certificate and add it (double click) to your Keychain
5. Make sure it is in your XCode Accounts

Then it works!

Hope it helps!

You can pass this to each block. See here: http://jsfiddle.net/yR7TZ/1/

LinkedHashMap insert = (LinkedHashMap) baseReq.get("insert");
LinkedHashMap delete = (LinkedHashMap) baseReq.get("delete");

The above Answer solves our problem but in addition to that. if we are trying to decompress a uncompressed("not a zip format") byte[] . we will get "Not in GZIP format" exception message.

For solving that we can add addition code in our Class.

public static boolean isCompressed(final byte[] compressed) {
    return (compressed[0] == (byte) (GZIPInputStream.GZIP_MAGIC)) && (compressed[1] == (byte) (GZIPInputStream.GZIP_MAGIC >> 8));
}

My Complete Compression Class with compress/decompress would look like:

import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZIPCompression {
  public static byte[] compress(final String str) throws IOException {
    if ((str == null) || (str.length() == 0)) {
      return null;
    }
    ByteArrayOutputStream obj = new ByteArrayOutputStream();
    GZIPOutputStream gzip = new GZIPOutputStream(obj);
    gzip.write(str.getBytes("UTF-8"));
    gzip.flush();
    gzip.close();
    return obj.toByteArray();
  }

  public static String decompress(final byte[] compressed) throws IOException {
    final StringBuilder outStr = new StringBuilder();
    if ((compressed == null) || (compressed.length == 0)) {
      return "";
    }
    if (isCompressed(compressed)) {
      final GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(compressed));
      final BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(gis, "UTF-8"));

      String line;
      while ((line = bufferedReader.readLine()) != null) {
        outStr.append(line);
      }
    } else {
      outStr.append(compressed);
    }
    return outStr.toString();
  }

  public static boolean isCompressed(final byte[] compressed) {
    return (compressed[0] == (byte) (GZIPInputStream.GZIP_MAGIC)) && (compressed[1] == (byte) (GZIPInputStream.GZIP_MAGIC >> 8));
  }
}

[Joke mode on]

You can fix this by adding this:

https://github.com/donavon/undefined-is-a-function

import { undefined } from 'undefined-is-a-function';
// Fixed! undefined is now a function.

[joke mode off]

here is another solution...

System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];

System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
    m.Write (buffer, 0, buffer.Length);
}  
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();

hope it helps!

We can directly specify the destination file with the dest option now. In the below example, the output json is stored into the /tmp/repo_version_file

- name: Get repository file repo_version model to set ambari_managed_repositories=false
  uri:
    url: 'http://<server IP>:8080/api/v1/stacks/HDP/versions/3.1/repository_versions/1?fields=operating_systems/*'
    method: GET
    force_basic_auth: yes
    user: xxxxx
    password: xxxxx
    headers:
      "X-Requested-By": "ambari"
      "Content-type": "Application/json"
    status_code: 200
    dest: /tmp/repo_version_file

Unfortunately, MySQL does not explicitly support that (except for dumping and reloading database again).

From http://dev.mysql.com/doc/refman/5.1/en/rename-database.html:

13.1.32. RENAME DATABASE Syntax

RENAME {DATABASE | SCHEMA} db_name TO new_db_name;

This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23. ... Use of this statement could result in loss of database contents, which is why it was removed. Do not use RENAME DATABASE in earlier versions in which it is present.

You don't need to use a type assertion, instead just use the %v format specifier with Sprintf:

hostAndPort := fmt.Sprintf("%v:%v", arguments["<host>"], arguments["<port>"])

If you need native data types for some reason (e.g. JSON serialization) this is my quick 'n' dirty way to do it:

data = [{'id': blog.pk, 'name': blog.name} for blog in blogs]

As you can see building the dict inside the list is not really DRY so if somebody knows a better way ...

Using pillow's fromarray, for example:

from PIL import Image
from numpy import *

im = array(Image.open('image.jpg'))
Image.fromarray(im).show()

You're allowed to have more than one return statement, so it's legal to write

if (some_condition) {
  return true;
}
return false;

It's also unnecessary to compare boolean values to true or false, so you can write

if (verifyPwd())  {
  // do_task
}

Edit: Sometimes you can't return early because there's more work to be done. In that case you can declare a boolean variable and set it appropriately inside the conditional blocks.

boolean success = true;

if (some_condition) {
  // Handle the condition.
  success = false;
} else if (some_other_condition) {
  // Handle the other condition.
  success = false;
}
if (another_condition) {
  // Handle the third condition.
}

// Do some more critical things.

return success;

SELECT chargeId, chargeType, MAX(serviceMonth) AS serviceMonth

GROUP BY chargeId, chargeType

I am trying to explain by putting problem statement and solution to it. I hope it will help

Problem Statement:

Find all the published products, whose name like ABC Product or PQR Product, and price should be less than 15/-

Solution:

Below are the conditions that need to be taken care of

1. Product price should be less than 15
2. Product name should be either ABC Product or PQR Product
3. Product should be in published state.

Below is the statement that applies above criterion to create query and fetch data.

$elements = $collection->find(
             Array(
                [price] => Array( [$lt] => 15 ),
                [$or] => Array(
                            [0]=>Array(
                                    [product_name]=>Array(
                                       [$in]=>Array(
                                            [0] => ABC Product,
                                            [1]=> PQR Product
                                            )
                                        )
                                    )
                                ),
                [state]=>Published
                )
            );

You could try using AJAX calls with jQuery. Like how youtube adds your comment without refreshing. This would remove the problem with refreshing overal.

You'd need to send the info necessary trough the ajax call.
I'll use the youtube comment as example.

$.ajax({
    type: 'POST',
    url: 'ajax/comment-on-video.php',
    data: {
        comment: $('#idOfInputField').val();
     },
    success: function(obj) {
        if(obj === 'true') {
            //Some code that recreates the inserted comment on the page.
        }
    }
});

You can now create the file comment-on-video.php and create something like this:

<?php
    session_start();

    if(isset($_POST['comment'])) {
        $comment = mysqli_real_escape_string($db, $_POST['comment']);
        //Given you are logged in and store the user id in the session.
        $user = $_SESSION['user_id'];

        $query = "INSERT INTO `comments` (`comment_text`, `user_id`) VALUES ($comment, $user);";
        $result = mysqli_query($db, $query);

        if($result) {
            echo true;
            exit();
        }
    }
    echo false;
    exit();
?>

This worked for me perfectly.

Add this class navbar-fixed-bottom to your footer.

<div class="footer navbar-fixed-bottom">

I used it like this:

<div class="container-fluid footer navbar-fixed-bottom">
<!-- start footer -->
</div>

And it sets to bottom over the the full width.

Edit: This will set footer to always visible, it's something you need to take in consideration.

Here are a few ways to create a list with N of continuous natural numbers starting from 1.

1 range:

def numbers(n): 
    return range(1, n+1);

2 List Comprehensions:

def numbers(n):
    return [i for i in range(1, n+1)]

You may want to look into the method xrange and the concepts of generators, those are fun in python. Good luck with your Learning!

This is what worked for me...

import cv2
import numpy as np

#Created an image (really an ndarray) with three channels 
new_image = np.ndarray((3, num_rows, num_cols), dtype=int)

#Did manipulations for my project where my array values went way over 255
#Eventually returned numbers to between 0 and 255

#Converted the datatype to np.uint8
new_image = new_image.astype(np.uint8)

#Separated the channels in my new image
new_image_red, new_image_green, new_image_blue = new_image

#Stacked the channels
new_rgb = np.dstack([new_image_red, new_image_green, new_image_blue])

#Displayed the image
cv2.imshow("WindowNameHere", new_rgbrgb)
cv2.waitKey(0)

This command fix the issue. It worked for me:

sudo npm install -g --unsafe-perm=true --allow-root

You could write yourself a little function to do what you want:

import random
def randomDigits(digits):
    lower = 10**(digits-1)
    upper = 10**digits - 1
    return random.randint(lower, upper)

Basically, 10**(digits-1) gives you the smallest {digit}-digit number, and 10**digits - 1 gives you the largest {digit}-digit number (which happens to be the smallest {digit+1}-digit number minus 1!). Then we just take a random integer from that range.

Before you call setContentView(), call setTheme(android.R.style...) and just replace the ... with the theme that you want(Theme, Theme_NoTitleBar, etc.).

Or if your theme is a custom theme, then replace the entire thing, so you get setTheme(yourThemesResouceId)

By default, JPA providers access the values of entity fields and map those fields to database columns using the entity’s JavaBean property accessor (getter) and mutator (setter) methods. As such, the names and types of the private fields in an entity do not matter to JPA. Instead, JPA looks at only the names and return types of the JavaBean property accessors. You can alter this using the @javax.persistence.Access annotation, which enables you to explicitly specify the access methodology that the JPA provider should employ.

@Entity
@Access(AccessType.FIELD)
public class SomeEntity implements Serializable
{
...
}

The available options for the AccessType enum are PROPERTY (the default) and FIELD. With PROPERTY, the provider gets and sets field values using the JavaBean property methods. FIELD makes the provider get and set field values using the instance fields. As a best practice, you should just stick to the default and use JavaBean properties unless you have a compelling reason to do otherwise.

You can put these property annotations on either the private fields or the public accessor methods. If you use AccessType.PROPERTY (default) and annotate the private fields instead of the JavaBean accessors, the field names must match the JavaBean property names. However, the names do not have to match if you annotate the JavaBean accessors. Likewise, if you use AccessType.FIELD and annotate the JavaBean accessors instead of the fields, the field names must also match the JavaBean property names. In this case, they do not have to match if you annotate the fields. It’s best to just be consistent and annotate the JavaBean accessors for AccessType.PROPERTY and the fields for AccessType.FIELD.

It is important that you should never mix JPA property annotations and JPA field annotations in the same entity. Doing so results in unspecified behavior and is very likely to cause errors.

How W3C does?

Simply have a look a look at https://www.w3.org/. The image has a z-index:1, the text is here but behind because of the z-index:0 coupled to the position: absolute;

The original HTML:

<h1 class="logo">
    <a tabindex="2" accesskey="1" href="/">
        <img src="/2008/site/images/logo-w3c-mobile-lg" width="90" height="53" alt="W3C">
    </a>
    <span class="alt-logo">W3C</span>
</h1>

The original CSS:

#w3c_mast h1 a {
    display: block;
    float: left;
    background: url(../images/logo-w3c-screen-lg) no-repeat top left;
    width: 100%;
    height: 107px;
    position: relative;
    z-index: 1;
}
.alt-logo {
    display: block;
    position: absolute;
    left: 20px;
    z-index: 0;
    background-color: #fff;
}

You have to select the option in ArrayAdapter:

ArrayAdapter<String> adapter = new ArrayAdapter<String>
    (this, android.R.layout.simple_list_item_single_choice, countries);

It is a way to simplify error checking and avoid deep nested if's. For example:

do {
  // do something
  if (error) {
    break;
  }
  // do something else
  if (error) {
    break;
  }
  // etc..
} while (0);

To track down the correct parameters you need to go first to ?plot.default, which refers you to ?par and ?axis:

plot(1, 1 ,xlab="x axis", ylab="y axis",  pch=19,
           col.lab="red", cex.lab=1.5,    #  for the xlab and ylab
           col="green")                   #  for the points

In addition to the line.separator property, if you are using java 1.5 or later and the String.format (or other formatting methods) you can use %n as in

Calendar c = ...;
String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY%n", c); 
//Note `%n` at end of line                                  ^^

String s2 = String.format("Use %%n as a platform independent newline.%n"); 
//         %% becomes %        ^^
//                                        and `%n` becomes newline   ^^

See the Java 1.8 API for Formatter for more details.

This may not be an option for you, but if you can use the Parallel Extension for .NET then you could use Tasks instead of raw threads and then use Task.WaitAll() to wait for them to complete.

I was thundered when the following code worked.

import os

for file in os.listdir("../FutureBookList"):
    if file.endswith(".adoc"):
        filename, file_extension = os.path.splitext(file)
        print(filename)
        print(file_extension)
        continue
    else:
        continue

So, I checked the documentation and it says:

Changed in version 3.6: Accepts a path-like object.

path-like object:

An object representing a file system path. A path-like object is either a str or...

I did a little more digging and the following also works:

with open("../FutureBookList/file.txt") as file:
   data = file.read()

I use div instead of tables and am able to target classes within the main class, as below:

CSS

.main {
    .width: 800px;
    .margin: 0 auto;
    .text-align: center;
}
.main .table {
    width: 80%;
}
.main .row {
   / ***something ***/
}
.main .column {
    font-size: 14px;
    display: inline-block;
}
.main .left {
    width: 140px;
    margin-right: 5px;
    font-size: 12px;
}
.main .right {
    width: auto;
    margin-right: 20px;
    color: #fff;
    font-size: 13px;
    font-weight: normal;
}

HTML

<div class="main">
    <div class="table">
        <div class="row">
            <div class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

If you want to style a particular "cell" exclusively you can use another sub-class or the id of the div e.g:

.main #red { color: red; }

<div class="main">
    <div class="table">
        <div class="row">
            <div id="red" class="column left">Swing Over Bed</div>
            <div class="column right">650mm</div>
            <div class="column left">Swing In Gap</div>
            <div class="column right">800mm</div>
        </div>
    </div>
</div>

I've found two ways to refresh PHP content:

1. Using the HTML meta tag:

echo("<meta http-equiv='refresh' content='1'>"); //Refresh by HTTP 'meta'

2. Using PHP refresh rate:

$delay = 0; // Where 0 is an example of a time delay. You can use 5 for 5 seconds, for example!
header("Refresh: $delay;"); 

SELECT ...
SELECT SLEEP(5);
SELECT ...

But what are you using this for? Are you trying to circumvent/reinvent mutexes or transactions?

Another option if you don't have Python 2.6:

import commands
n = commands.getoutput("grep -c processor /proc/cpuinfo")

A wildcard * can be translated as .* or .*? regex pattern.

You might need to use a singleline mode to match newline symbols, and in this case, you can use (?s) as part of the regex pattern.

You can set it for the whole or part of the pattern:

X* = > @"X(?s:.*)"
*X = > @"(?s:.*)X"
*X* = > @"(?s).*X.*"
*X*YZ* = > @"(?s).*X.*YZ.*"
X*YZ*P = > @"(?s:X.*YZ.*P)"

I am posting an answer to provide an updated solution and explanation as to why this problem can occur. Say you are getting this data from a database or Excel workbook. If you have special characters like La Cañada Flintridge city, well unless you are exporting the data using UTF-8 encoding, you're going to introduce errors. La Cañada Flintridge city will become La Ca\xf1ada Flintridge city. If you are using pandas.read_csv without any adjustments to the default parameters, you'll hit the following error

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 5: invalid continuation byte

Fortunately, there are a few solutions.

Option 1, fix the exporting. Be sure to use UTF-8 encoding.

Option 2, if fixing the exporting problem is not available to you, and you need to use pandas.read_csv, be sure to include the following paramters, engine='python'. By default, pandas uses engine='C' which is great for reading large clean files, but will crash if anything unexpected comes up. In my experience, setting encoding='utf-8' has never fixed this UnicodeDecodeError. Also, you do not need to use errors_bad_lines, however, that is still an option if you REALLY need it.

pd.read_csv(<your file>, engine='python')

Option 3: solution is my preferred solution personally. Read the file using vanilla Python.

import pandas as pd

data = []

with open(<your file>, "rb") as myfile:
    # read the header seperately
    # decode it as 'utf-8', remove any special characters, and split it on the comma (or deliminator)
    header = myfile.readline().decode('utf-8').replace('\r\n', '').split(',')
    # read the rest of the data
    for line in myfile:
        row = line.decode('utf-8', errors='ignore').replace('\r\n', '').split(',')
        data.append(row)

# save the data as a dataframe
df = pd.DataFrame(data=data, columns = header)

Hope this helps people encountering this issue for the first time.

I do believe that putting a regular expression in the str.split parentheses should solve the issue. The Java String.split() method is based upon regular expressions so what you need is:

str = "Hello I'm your String";
String[] splitStr = str.split("\\s+");

You can do it by using angular events that is $emit and $broadcast. As per our knowledge this is the best, efficient and effective way.

First we call a function from one controller.

var myApp = angular.module('sample', []);
myApp.controller('firstCtrl', function($scope) {
    $scope.sum = function() {
        $scope.$emit('sumTwoNumber', [1, 2]);
    };
});
myApp.controller('secondCtrl', function($scope) {
    $scope.$on('sumTwoNumber', function(e, data) {
        var sum = 0;
        for (var a = 0; a < data.length; a++) {
            sum = sum + data[a];
        }
        console.log('event working', sum);

    });
});

You can also use $rootScope in place of $scope. Use your controller accordingly.

You can declare variables within a switch statement if you start a new block:

switch (thing)
{ 
  case A:
  {
    int i = 0;  // Completely legal
  }
  break;
}

The reason is to do with allocating (and reclaiming) space on the stack for storage of the local variable(s).

From Wikipedia:

In computer programming, boilerplate is the term used to describe sections of code that have to be included in many places with little or no alteration. It is more often used when referring to languages that are considered verbose, i.e. the programmer must write a lot of code to do minimal jobs.

So basically you can consider boilerplate code as a text that is needed by a programming language very often all around the programs you write in that language.

Modern languages are trying to reduce it, but also the older language which has specific type-checkers (for example OCaml has a type-inferrer that allows you to avoid so many declarations that would be boilerplate code in a more verbose language like Java)

When we open a modal it accept size as a paramenter:

Possible values for it size: sm, md, lg

$scope.openModal = function (size) {
var modal = $modal.open({
      size: size,
      templateUrl: "/app/user/welcome.html",
      ...... 
      });
}

HTML:

<button type="button" 
    class="btn btn-default" 
    ng-click="openModal('sm')">Small Modal</button>

<button type="button" 
    class="btn btn-default" 
    ng-click="openModal('md')">Medium Modal</button>

<button type="button" 
    class="btn btn-default" 
    ng-click="openModal('lg')">Large Modal</button>

If you want any specific size, add style on model HTML:

<style>.modal-dialog {width: 500px;} </style>

First you have to create a li(with id and value as you required) then add it to your ul.

Javascript ::

addAnother = function() {
    var ul = document.getElementById("list");
    var li = document.createElement("li");
    var children = ul.children.length + 1
    li.setAttribute("id", "element"+children)
    li.appendChild(document.createTextNode("Element "+children));
    ul.appendChild(li)
}

Check this example that add li element to ul.

The abort function does this. For example:

abort("Message goes here")

Note: the abort message will be written to STDERR as opposed to puts which will write to STDOUT.

My cause was different I referenced a web service then I got this message.

Then I changed my target .Net Framework 4.0 to .Net Framework 2.0 and re-refer my webservice. After a few changes problem solved. There is no error worked fine.

hope this helps!

"N/A" is a string and cannot be converted to a number. Catch the exception and handle it. For example:

    String text = "N/A";
    int intVal = 0;
    try {
        intVal = Integer.parseInt(text);
    } catch (NumberFormatException e) {
        //Log it if needed
        intVal = //default fallback value;
    }

Have you been using menu Analyze → Performance and Diagnostics? I have! It's awesome! But you may want to clean up.

Open the Performance Explorer. If you collapse all of the items in there, select all, then you can right click and do Delete.

My solution opens faster and is in general running much faster now.

Also you may notice changes to your sln file as shown. For me, this section was deleted from the sln.

• Install chocolatey from here.

• Then, choco install make.

Now you will be able to use Make on windows.

You don't need ng-checked when you use ng-model. If you're performing CRUD on your HTML Form, just create a model for CREATE mode that is consistent with your EDIT mode during the data-binding:

CREATE Mode: Model with default values only

$scope.dataModel = {
   isItemSelected: true,
   isApproved: true,
   somethingElse: "Your default value"
}

EDIT Mode: Model from database

$scope.dataModel = getFromDatabaseWithSameStructure()

Then whether EDIT or CREATE mode, you can consistently make use of your ng-model to sync with your database.

numpy 1D array --> column/row matrix:

>>> a=np.array([1,2,4])
>>> a[:, None]    # col
array([[1],
       [2],
       [4]])
>>> a[None, :]    # row, or faster `a[None]`
array([[1, 2, 4]])

And as @joe-kington said, you can replace None with np.newaxis for readability.

If you happen to be using Microsoft IIS server, in addition to the php.ini settings mentioned by others, you may need to increase the execution timeout settings for the PHP FastCGI application in the IIS Server Manager:

Step 1) Open the IIS Server Manager (usually under Server Manager in the Start Menu, then Tools / Internet Information Services (IIS) Manager).

Step 2) Click on the main connection (not specific to any particular domain).

Step 3) Under the IIS section, find FastCGI Settings (shown below).

Step 4) Therein, right-click the PHP application and select Edit....

Step 5) Check the timeouts (shown below).

In my case, the default timeouts here were 70 and 90 seconds; the former of which was causing a 500 Internal Server Error on PHP scripts that took longer than 70 seconds.

Copy should be used for NSString. If it's Mutable, then it gets copied. If it's not, then it just gets retained. Exactly the semantics that you want in an app (let the type do what's best).

Let's say the list is:

<ul>
 <li>item1</li>
 <li>item2</li>
 <li>item3</li>
</ul>

For this example. If I understand correctly, you want the list items to be in the middle of the screen, but you want the text IN those list items to be centered to the left of the list item itself. Doing that is actually pretty easy. You just need some CSS:

ul {
    display: table; 
    margin: 0 auto;
    text-align: left;
}

And it works! Here is what is happening. First, we say we want to affect only unordered lists. Then, we do Rafael Herscovici's trick for centering the list items. Finally, we say to align the text to the left of the list items.

The examples above work fine when there is only one delimiter, but it doesn't scale well for multiple delimiters. Note that this will only work for SQL Server 2016 and above.

/*Split based on delimeter*/

    SELECT A.id, X1.VALUE, ROW_NUMBER() OVER (PARTITION BY A.id ORDER BY A.id) RN

    CROSS APPLY STRING_SPLIT(A.name, '/') X1
    ) A

Oracle's security model is such that when executing dynamic SQL using Execute Immediate (inside the context of a PL/SQL block or procedure), the user does not have privileges to objects or commands that are granted via role membership. Your user likely has "DBA" role or something similar. You must explicitly grant "drop table" permissions to this user. The same would apply if you were trying to select from tables in another schema (such as sys or system) - you would need to grant explicit SELECT privileges on that table to this user.

The contents of the CSS file (from the include URL) depends on what browser I view it from. For example, when browsing to http://fonts.googleapis.com/css?family=Open+Sans using Chrome, the file only contained WOFF links. Using Internet Explorer (below), it included both EOT and WOFF. I pasted all the links into my browser to download them.

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 400;
  src: url(http://themes.googleusercontent.com/static/fonts/opensans/v6/cJZKeOuBrn4kERxqtaUH3fY6323mHUZFJMgTvxaG2iE.eot);

When you host your own web fonts, you need to correctly link to each font type, deal with legacy browser bugs, etc. When you use Google Web Fonts (hosted by Google), Google automatically links to the correct font types for that browser.

I came across .netrc and found it relevant to this.

Create a file ~/.netrc with the following content:

machine github.com
    login <github username>
    password <github password or Personal access tokens >

Done!

Additionally, for latest GO versions, you might need to add this to the environment variables GOPRIVATE=github.com (I've added it to my .zshrc)

netrc also makes my development environment setup better as my personal github access for HTTPS is been configured now to be used across the machine (just like my SSH configuration).

Generate GitHub personal access tokens: https://github.com/settings/tokens

See this answer for its use with Git on Windows specifically

Ref: netrc man page

If you want to stick with the SSH authentication, then mask the request to use ssh forcefully

git config --global url."[email protected]:".insteadOf "https://github.com/"

With localStorage, web applications can store data locally within the user's browser. Before HTML5, application data had to be stored in cookies, included in every server request. Large amounts of data can be stored locally, without affecting website performance. Although localStorage is more modern, there are some pros and cons to both techniques.

Cookies

Pros

• Legacy support (it's been around forever)
• Persistent data
• Expiration dates

Cons

• Each domain stores all its cookies in a single string, which can make parsing data difficult
• Data is unencrypted, which becomes an issue because... ... though small in size, cookies are sent with every HTTP request Limited size (4KB)
• SQL injection can be performed from a cookie

Local storage

Pros

• Support by most modern browsers
• Persistent data that is stored directly in the browser
• Same-origin rules apply to local storage data
• Is not sent with every HTTP request
• ~5MB storage per domain (that's 5120KB)

Cons

• Not supported by anything before: IE 8, Firefox 3.5, Safari 4, Chrome 4, Opera 10.5, iOS 2.0, Android 2.0
• If the server needs stored client information you purposely have to send it.

localStorage usage is almost identical with the session one. They have pretty much exact methods, so switching from session to localStorage is really child's play. However, if stored data is really crucial for your application, you will probably use cookies as a backup in case localStorage is not available. If you want to check browser support for localStorage, all you have to do is run this simple script:

/* 
* function body that test if storage is available
* returns true if localStorage is available and false if it's not
*/
function lsTest(){
    var test = 'test';
    try {
        localStorage.setItem(test, test);
        localStorage.removeItem(test);
        return true;
    } catch(e) {
        return false;
    }
}

/* 
* execute Test and run our custom script 
*/
if(lsTest()) {
    // window.sessionStorage.setItem(name, 1); // session and storage methods are very similar
    window.localStorage.setItem(name, 1);
    console.log('localStorage where used'); // log
} else {
    document.cookie="name=1; expires=Mon, 28 Mar 2016 12:00:00 UTC";
    console.log('Cookie where used'); // log
}

"localStorage values on Secure (SSL) pages are isolated" as someone noticed keep in mind that localStorage will not be available if you switch from 'http' to 'https' secured protocol, where the cookie will still be accesible. This is kind of important to be aware of if you work with secure protocols.

The exact question is how to do it with pure JavaScript not with jQuery.

But I always use the solution that can be found in jQuery's source code. It's just one line of native JavaScript.

For me it's the best, easy readable and even afaik the shortest way to get the iframes content.

First get your iframe

var iframe = document.getElementById('id_description_iframe');

// or
var iframe = document.querySelector('#id_description_iframe');

And then use jQuery's solution

var iframeDocument = iframe.contentDocument || iframe.contentWindow.document;

It works even in the Internet Explorer which does this trick during the contentWindow property of the iframe object. Most other browsers uses the contentDocument property and that is the reason why we proof this property first in this OR condition. If it is not set try contentWindow.document.

Select elements in iframe

Then you can usually use getElementById() or even querySelectorAll() to select the DOM-Element from the iframeDocument:

if (!iframeDocument) {
    throw "iframe couldn't be found in DOM.";
}

var iframeContent = iframeDocument.getElementById('frameBody');

// or
var iframeContent = iframeDocument.querySelectorAll('#frameBody');

Call functions in the iframe

Get just the window element from iframe to call some global functions, variables or whole libraries (e.g. jQuery):

var iframeWindow = iframe.contentWindow;

// you can even call jQuery or other frameworks
// if it is loaded inside the iframe
iframeContent = iframeWindow.jQuery('#frameBody');

// or
iframeContent = iframeWindow.$('#frameBody');

// or even use any other global variable
iframeWindow.myVar = window.myVar;

// or call a global function
var myVar = iframeWindow.myFunction(param1 /*, ... */);

Note

All this is possible if you observe the same-origin policy.

You can first start IIS express from command line and give it a port with /port:port-number see other options.

What #defines are set up by Xcode when compiling for iPhone

I'll repeat my answer from there:

It's in the SDK docs under "Compiling source code conditionally"

The relevant definition is TARGET_OS_SIMULATOR, which is defined in /usr/include/TargetConditionals.h within the iOS framework. On earlier versions of the toolchain, you had to write:

#include "TargetConditionals.h"

but this is no longer necessary on the current (Xcode 6/iOS8) toolchain.

So, for example, if you want to check that you are running on device, you should do

#if TARGET_OS_SIMULATOR
    // Simulator-specific code
#else
    // Device-specific code
#endif

depending on which is appropriate for your use-case.

In Visual Studio 2017, go to menu Tools → NuGet Package Manager → Package Manager Settings. You may find out a button, Clear All NuGet Cache(s):

If you are using .NET Core, you may clear the cache with this command, which should work as of .NET Core tools 1.0:

dotnet nuget locals all --clear

df['newcol'] = arr.toarray().tolist()
print(df)

yields

   0  1  2     newcol
0  1  2  3  [0, 1, 0]
1  4  5  6  [0, 0, 1]
2  7  8  9  [1, 0, 0]

The simplest answer is to ensure that your pod or replication controller yaml/json files add the pod IP as an environment variable by adding the config block defined below. (the block below additionally makes the name and namespace available to the pod)

env:
- name: MY_POD_NAME
  valueFrom:
    fieldRef:
      fieldPath: metadata.name
- name: MY_POD_NAMESPACE
  valueFrom:
    fieldRef:
      fieldPath: metadata.namespace
- name: MY_POD_IP
  valueFrom:
    fieldRef:
      fieldPath: status.podIP

Recreate the pod/rc and then try

echo $MY_POD_IP

also run env to see what else kubernetes provides you with.

Right-click My Computer -> Manage -> Services Choose "Services" under the "Services and Application" from right pane Then search for the "mysql" Service. When you find it, double click to start that service.

Now you should be able to run and login to PhpMyAdmin

I had a similar problem. I was attempting to have a file written every time a user visits a website.

The problem ended up being twofold.

1: the permissions were not set correctly

2: I attempted to use
f = open(r"newfile.txt","w+") (Wrong)

After changing the file to 777 (all users can read/write)
chmod 777 /var/www/path/to/file
and changing the path to an absolute path, my problem was solved
f = open(r"/var/www/path/to/file/newfile.txt","w+") (Right)

Have you tried this:

gitk path/to/file

To specify a port for the ASP.NET Development Server

• In Solution Explorer, click the name of the application.

• In the Properties pane, click the down-arrow beside Use dynamic ports and select False from the dropdown list.

• This will enable editing of the Port number property.

• In the Properties pane, click the text box beside Port number and
  type in a port number. Click outside of the Properties pane. This
  saves the property settings.

• Each time you run a file-system Web site within Visual Web Developer, the ASP.NET Development Server will listen on the specified port.

Hope this helps.

Deleting duplicate rows in MySQL in-place, (Assuming you have a timestamp col to sort by) walkthrough:

Create the table and insert some rows:

create table penguins(foo int, bar varchar(15), baz datetime);
insert into penguins values(1, 'skipper', now());
insert into penguins values(1, 'skipper', now());
insert into penguins values(3, 'kowalski', now());
insert into penguins values(3, 'kowalski', now());
insert into penguins values(3, 'kowalski', now());
insert into penguins values(4, 'rico', now());
select * from penguins;
    +------+----------+---------------------+
    | foo  | bar      | baz                 |
    +------+----------+---------------------+
    |    1 | skipper  | 2014-08-25 14:21:54 |
    |    1 | skipper  | 2014-08-25 14:21:59 |
    |    3 | kowalski | 2014-08-25 14:22:09 |
    |    3 | kowalski | 2014-08-25 14:22:13 |
    |    3 | kowalski | 2014-08-25 14:22:15 |
    |    4 | rico     | 2014-08-25 14:22:22 |
    +------+----------+---------------------+
6 rows in set (0.00 sec)

Remove the duplicates in place:

delete a
    from penguins a
    left join(
    select max(baz) maxtimestamp, foo, bar
    from penguins
    group by foo, bar) b
    on a.baz = maxtimestamp and
    a.foo = b.foo and
    a.bar = b.bar
    where b.maxtimestamp IS NULL;
Query OK, 3 rows affected (0.01 sec)
select * from penguins;
+------+----------+---------------------+
| foo  | bar      | baz                 |
+------+----------+---------------------+
|    1 | skipper  | 2014-08-25 14:21:59 |
|    3 | kowalski | 2014-08-25 14:22:15 |
|    4 | rico     | 2014-08-25 14:22:22 |
+------+----------+---------------------+
3 rows in set (0.00 sec)

You're done, duplicate rows are removed, last one by timestamp is kept.

For those of you without a timestamp or unique column.

You don't have a timestamp or a unique index column to sort by? You're living in a state of degeneracy. You'll have to do additional steps to delete duplicate rows.

create the penguins table and add some rows

create table penguins(foo int, bar varchar(15)); 
insert into penguins values(1, 'skipper'); 
insert into penguins values(1, 'skipper'); 
insert into penguins values(3, 'kowalski'); 
insert into penguins values(3, 'kowalski'); 
insert into penguins values(3, 'kowalski'); 
insert into penguins values(4, 'rico'); 
select * from penguins; 
    # +------+----------+ 
    # | foo  | bar      | 
    # +------+----------+ 
    # |    1 | skipper  | 
    # |    1 | skipper  | 
    # |    3 | kowalski | 
    # |    3 | kowalski | 
    # |    3 | kowalski | 
    # |    4 | rico     | 
    # +------+----------+ 

make a clone of the first table and copy into it.

drop table if exists penguins_copy; 
create table penguins_copy as ( SELECT foo, bar FROM penguins );  

#add an autoincrementing primary key: 
ALTER TABLE penguins_copy ADD moo int AUTO_INCREMENT PRIMARY KEY first; 

select * from penguins_copy; 
    # +-----+------+----------+ 
    # | moo | foo  | bar      | 
    # +-----+------+----------+ 
    # |   1 |    1 | skipper  | 
    # |   2 |    1 | skipper  | 
    # |   3 |    3 | kowalski | 
    # |   4 |    3 | kowalski | 
    # |   5 |    3 | kowalski | 
    # |   6 |    4 | rico     | 
    # +-----+------+----------+ 

The max aggregate operates upon the new moo index:

delete a from penguins_copy a left join( 
    select max(moo) myindex, foo, bar 
    from penguins_copy 
    group by foo, bar) b 
    on a.moo = b.myindex and 
    a.foo = b.foo and 
    a.bar = b.bar 
    where b.myindex IS NULL; 

#drop the extra column on the copied table 
alter table penguins_copy drop moo; 
select * from penguins_copy; 

#drop the first table and put the copy table back: 
drop table penguins; 
create table penguins select * from penguins_copy; 

observe and cleanup

drop table penguins_copy; 
select * from penguins;
+------+----------+ 
| foo  | bar      | 
+------+----------+ 
|    1 | skipper  | 
|    3 | kowalski | 
|    4 | rico     | 
+------+----------+ 
    Elapsed: 1458.359 milliseconds 

What's that big SQL delete statement doing?

Table penguins with alias 'a' is left joined on a subset of table penguins called alias 'b'. The right hand table 'b' which is a subset finds the max timestamp [ or max moo ] grouped by columns foo and bar. This is matched to left hand table 'a'. (foo,bar,baz) on left has every row in the table. The right hand subset 'b' has a (maxtimestamp,foo,bar) which is matched to left only on the one that IS the max.

Every row that is not that max has value maxtimestamp of NULL. Filter down on those NULL rows and you have a set of all rows grouped by foo and bar that isn't the latest timestamp baz. Delete those ones.

Make a backup of the table before you run this.

Prevent this problem from ever happening again on this table:

If you got this to work, and it put out your "duplicate row" fire. Great. Now define a new composite unique key on your table (on those two columns) to prevent more duplicates from being added in the first place.

Like a good immune system, the bad rows shouldn't even be allowed in to the table at the time of insert. Later on all those programs adding duplicates will broadcast their protest, and when you fix them, this issue never comes up again.

AFAIK, you have to convert it to grayscale and then threshold it to binary.

1. Read the image as a grayscale image If you're reading the RGB image from disk, then you can directly read it as a grayscale image, like this:

// C
IplImage* im_gray = cvLoadImage("image.jpg",CV_LOAD_IMAGE_GRAYSCALE);

// C++ (OpenCV 2.0)
Mat im_gray = imread("image.jpg",CV_LOAD_IMAGE_GRAYSCALE);

2. Convert an RGB image im_rgb into a grayscale image: Otherwise, you'll have to convert the previously obtained RGB image into a grayscale image

// C
IplImage *im_rgb  = cvLoadImage("image.jpg");
IplImage *im_gray = cvCreateImage(cvGetSize(im_rgb),IPL_DEPTH_8U,1);
cvCvtColor(im_rgb,im_gray,CV_RGB2GRAY);

// C++
Mat im_rgb  = imread("image.jpg");
Mat im_gray;
cvtColor(im_rgb,im_gray,CV_RGB2GRAY);

3. Convert to binary You can use adaptive thresholding or fixed-level thresholding to convert your grayscale image to a binary image.

E.g. in C you can do the following (you can also do the same in C++ with Mat and the corresponding functions):

// C
IplImage* im_bw = cvCreateImage(cvGetSize(im_gray),IPL_DEPTH_8U,1);
cvThreshold(im_gray, im_bw, 128, 255, CV_THRESH_BINARY | CV_THRESH_OTSU);

// C++
Mat img_bw = im_gray > 128;

In the above example, 128 is the threshold.

4. Save to disk

// C
cvSaveImage("image_bw.jpg",img_bw);

// C++
imwrite("image_bw.jpg", img_bw);

Using #killall command:

#killall -9 <processname>

Use the following

1.) Choose the image you want to set in your title bar.
2.) Convert it to ".ico" format. (You can use the following link online) http://image.online-convert.com/convert-to-ico
3.) Save the file as "favicon.ico" in the same folder as your .html file
4.) Add this inside your head tag <link rel="shortcut icon" href="favicon.ico"/>

For this purpose I would suggest just do the following thing -

int(round(x))

This will give you nearest integer.

Hope this helps!!

When do I need to declare them myself?

The Rule of Three states that if you declare any of a

1. copy constructor
2. copy assignment operator
3. destructor

then you should declare all three. It grew out of the observation that the need to take over the meaning of a copy operation almost always stemmed from the class performing some kind of resource management, and that almost always implied that

• whatever resource management was being done in one copy operation probably needed to be done in the other copy operation and

• the class destructor would also be participating in management of the resource (usually releasing it). The classic resource to be managed was memory, and this is why all Standard Library classes that manage memory (e.g., the STL containers that perform dynamic memory management) all declare “the big three”: both copy operations and a destructor.

A consequence of the Rule of Three is that the presence of a user-declared destructor indicates that simple member wise copy is unlikely to be appropriate for the copying operations in the class. That, in turn, suggests that if a class declares a destructor, the copy operations probably shouldn’t be automatically generated, because they wouldn’t do the right thing. At the time C++98 was adopted, the significance of this line of reasoning was not fully appreciated, so in C++98, the existence of a user declared destructor had no impact on compilers’ willingness to generate copy operations. That continues to be the case in C++11, but only because restricting the conditions under which the copy operations are generated would break too much legacy code.

How can I prevent my objects from being copied?

Declare copy constructor & copy assignment operator as private access specifier.

class MemoryBlock
{
public:

//code here

private:
MemoryBlock(const MemoryBlock& other)
{
   cout<<"copy constructor"<<endl;
}

// Copy assignment operator.
MemoryBlock& operator=(const MemoryBlock& other)
{
 return *this;
}
};

int main()
{
   MemoryBlock a;
   MemoryBlock b(a);
}

In C++11 onwards you can also declare copy constructor & assignment operator deleted

class MemoryBlock
{
public:
MemoryBlock(const MemoryBlock& other) = delete

// Copy assignment operator.
MemoryBlock& operator=(const MemoryBlock& other) =delete
};


int main()
{
   MemoryBlock a;
   MemoryBlock b(a);
}

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

Here is a talk about the differences between web sockets and server sent events. Since Java EE 7 a WebSocket API is already part of the specification and it seems that server sent events will be released in the next version of the enterprise edition.

This is how I do it:

>>> import traceback
>>> try:
...   int('k')
... except:
...   var = traceback.format_exc()
... 
>>> print var
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ValueError: invalid literal for int() with base 10: 'k'

You should however take a look at the traceback documentation, as you might find there more suitable methods, depending to how you want to process your variable afterwards...

The issue was in my code.

In large code base, issue was not clear.

A simplified code is below:

Bad:

 collection.insertMany(
    [[],
    function (err, result) {
    });

Good:

collection.insertMany(
    [],
    function (err, result) {
    });

That is, the first one has [[], instead of normal array []

TS error was not clear enough, and it showed error in the last line with });

Hope this helps.

Define width of .absorbing-column

Set table-layout to auto and define an extreme width on .absorbing-column.

Here I have set the width to 100% because it ensures that this column will take the maximum amount of space allowed, while the columns with no defined width will reduce to fit their content and no further.

This is one of the quirky benefits of how tables behave. The table-layout: auto algorithm is mathematically forgiving.

You may even choose to define a min-width on all td elements to prevent them from becoming too narrow and the table will behave nicely.

table {_x000D_
    table-layout: auto;_x000D_
    border-collapse: collapse;_x000D_
    width: 100%;_x000D_
}_x000D_
table td {_x000D_
    border: 1px solid #ccc;_x000D_
}_x000D_
table .absorbing-column {_x000D_
    width: 100%;_x000D_
}

<table>_x000D_
  <thead>_x000D_
    <tr>_x000D_
      <th>Column A</th>_x000D_
      <th>Column B</th>_x000D_
      <th>Column C</th>_x000D_
      <th class="absorbing-column">Column D</th>_x000D_
    </tr>_x000D_
  </thead>_x000D_
  <tbody>_x000D_
    <tr>_x000D_
      <td>Data A.1 lorem</td>_x000D_
      <td>Data B.1 ip</td>_x000D_
      <td>Data C.1 sum l</td>_x000D_
      <td>Data D.1</td>_x000D_

Here's what I use. If it fails to pretty print the JSON it just returns the original string. Useful for printing HTTP responses that should contain JSON.

import (
    "encoding/json"
    "bytes"
)

func jsonPrettyPrint(in string) string {
    var out bytes.Buffer
    err := json.Indent(&out, []byte(in), "", "\t")
    if err != nil {
        return in
    }
    return out.String()
}

I use:

NSInteger stringToInt(NSString *string) {
    return [string integerValue];
}

And vice versa:

NSString* intToString(NSInteger integer) {
    return [NSString stringWithFormat:@"%d", integer];
}

That's a great question. I think @Diederik has a good answer, although it's unfortunate that Cocoa doesn't have a mechanism for exactly what you want to do.

NSInputStream allows you to read chunks of N bytes (very similar to java.io.BufferedReader), but you have to convert it to an NSString on your own, then scan for newlines (or whatever other delimiter) and save any remaining characters for the next read, or read more characters if a newline hasn't been read yet. (NSFileHandle lets you read an NSData which you can then convert to an NSString, but it's essentially the same process.)

Apple has a Stream Programming Guide that can help fill in the details, and this SO question may help as well if you're going to be dealing with uint8_t* buffers.

If you're going to be reading strings like this frequently (especially in different parts of your program) it would be a good idea to encapsulate this behavior in a class that can handle the details for you, or even subclassing NSInputStream (it's designed to be subclassed) and adding methods that allow you to read exactly what you want.

For the record, I think this would be a nice feature to add, and I'll be filing an enhancement request for something that makes this possible. :-)

Edit: Turns out this request already exists. There's a Radar dating from 2006 for this (rdar://4742914 for Apple-internal people).

This also works:

zip(*elements)[1]

(I am mainly posting this, to prove to myself that I have groked zip...)

See it in action:

>>> help(zip)

Help on built-in function zip in module builtin:

zip(...)

zip(seq1 [, seq2 [...]]) -> [(seq1[0], seq2[0] ...), (...)]

Return a list of tuples, where each tuple contains the i-th element from each of the argument sequences. The returned list is truncated in length to the length of the shortest argument sequence.

>>> elements = [(1,1,1),(2,3,7),(3,5,10)]
>>> zip(*elements)
[(1, 2, 3), (1, 3, 5), (1, 7, 10)]
>>> zip(*elements)[1]
(1, 3, 5)
>>>

Neat thing I learned today: Use *list in arguments to create a parameter list for a function...

Note: In Python3, zip returns an iterator, so instead use list(zip(*elements)) to return a list of tuples.

Shutdown hooks execute in all cases where the VM is not forcibly killed. So, if you were to issue a "standard" kill (SIGTERM from a kill command) then they will execute. Similarly, they will execute after calling System.exit(int).

However a hard kill (kill -9 or kill -SIGKILL) then they won't execute. Similarly (and obviously) they won't execute if you pull the power from the computer, drop it into a vat of boiling lava, or beat the CPU into pieces with a sledgehammer. You probably already knew that, though.

Finalizers really should run as well, but it's best not to rely on that for shutdown cleanup, but rather rely on your shutdown hooks to stop things cleanly. And, as always, be careful with deadlocks (I've seen far too many shutdown hooks hang the entire process)!

You can do something like this to read your nodes.

Also you can find some explanation in this page http://www.compoc.com/tuts/

<script type="text/javascript">
        var markers = null;
        $(document).ready(function () {
            $.get("File.xml", {}, function (xml){
              $('marker',xml).each(function(i){
                 markers = $(this);
              });
            });
        });
</script>

Due to the locking implementation issues, MySQL does not allow referencing the affected table with DELETE or UPDATE.

You need to make a JOIN here instead:

DELETE  gc.*
FROM    guide_category AS gc 
LEFT JOIN
        guide AS g 
ON      g.id_guide = gc.id_guide
WHERE   g.title IS NULL

or just use a NOT IN:

DELETE  
FROM    guide_category AS gc 
WHERE   id_guide NOT IN
        (
        SELECT  id_guide
        FROM    guide
        )

I think that Object = Instance. Reference is a "link" to an Object.

Car c = new Car();

variable c stores a reference to an object of type Car.

If you mean if you can do ctor chaining in C#, the answer is yes. The question has already been asked.

However it seems from the comments, it seems what you really intend to ask is 'Can I call an overloaded constructor from within another constructor with pre/post processing?'
Although C# doesn't have the syntax to do this, you could do this with a common initialization function (like you would do in C++ which doesn't support ctor chaining)

class A
{
  //ctor chaining
  public A() : this(0)
  {  
      Console.WriteLine("default ctor"); 
  }

  public A(int i)
  {  
      Init(i); 
  }

  // what you want
  public A(string s)
  {  
      Console.WriteLine("string ctor overload" );
      Console.WriteLine("pre-processing" );
      Init(Int32.Parse(s));
      Console.WriteLine("post-processing" );
  }

   private void Init(int i)
   {
      Console.WriteLine("int ctor {0}", i);
   }
}

HttpClient.get() applies res.json() automatically and returns Observable<HttpResponse<string>>. You no longer need to call this function yourself.

Use Runtime to call Curl. This code works for both Ubuntu and Windows.

String[] commands = new String {"curl", "-X", "GET", "http://checkip.amazonaws.com"};
Process process = Runtime.getRuntime().exec(commands);
BufferedReader reader = new BufferedReader(new 
InputStreamReader(process.getInputStream()));
String line;
String response;
while ((line = reader.readLine()) != null) {
    response.append(line);
}

    NSError *error;
    [[NSFileManager defaultManager] removeItemAtPath:new_file_path_str error:&error];
    if (error){
        NSLog(@"%@", error);
    }

Alternatively one can use the setExtremes method also,

yAxis.setExtremes(0, 100);

Or if only one value is needed to be set, just leave other as null

yAxis.setExtremes(null, 100);

Your case is an extreme one, but here is a solution for others that fits a more common scenario of wanting to style fewer than 4 borders exactly the same.

border: 1px dashed red; border-width: 1px 1px 0 1px;

that is a little shorter, and maybe easier to read than

border-top: 1px dashed red;  border-right: 1px dashed red; border-left: 1px dashed red;

or

border-color: red; border-style: dashed; border-width: 1px 1px 0 1px;

This problem is from the lazy update data request of Chrome. At the first time you go to homepage. Chrome request with empty data. Then you go to the login page and logged in. When you back home page Chrome lazy to update the cookie data request because this domain is the same with the first time you access. Solution: Add parameter for home url. That helps Chrome realizes that this request need to update cookie to call to the server.

add at dashboard page

<?php 
$track = '?track='.uniqid();
?>
<a href="<?= get_home_url(). $track ?>"> <img src="/img/logo.svg"></a>

I have Done through git bash:

(use "git checkout -- <file>..." to discard changes in working directory)

1. Git status. [So we have seen one file wad modified.]
2. git checkout -- index.html [i have changed in index.html file :
3. git status [now those changes was removed]

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video

        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

The reason behind this error is : Flask app is already running, hasn't shut down and in middle of that we try to start another instance by: with app.app_context(): #Code Before we use this with statement we need to make sure that scope of the previous running app is closed.

This is older but placing this here for my reference too. boto3.resource is just implementing the default Session, you can pass through boto3.resource session details.

Help on function resource in module boto3:

resource(*args, **kwargs)
    Create a resource service client by name using the default session.

    See :py:meth:`boto3.session.Session.resource`.

https://github.com/boto/boto3/blob/86392b5ca26da57ce6a776365a52d3cab8487d60/boto3/session.py#L265

you can see that it just takes the same arguments as Boto3.Session

import boto3
S3 = boto3.resource('s3', region_name='us-west-2', aws_access_key_id=settings.AWS_SERVER_PUBLIC_KEY, aws_secret_access_key=settings.AWS_SERVER_SECRET_KEY)
S3.Object( bucket_name, key_name ).delete()

You are grouping by month only, you have to add YEAR() to the group by

All you have to do is open Anaconda Prompt and type

pip install package-name

It will automatically install to the anaconda environment without having to use

conda install package-name

Since some of the conda packages may lack support overtime it is required to install using pip and this is one way to do it

If you have pip installed in anaconda you can run the following in jupyter notebook or in your python shell that is linked to anaconda

pip.main(['install', 'package-name'])

Check your version of pip with pip.__version__. If it is version 10.x.x or above, then install your python package with this line of code

subprocess.check_call([sys.executable, '-m', 'pip', 'install', '--upgrade', 'package-name'])

In your jupyter notebook, you can install python packages through pip in a cell this way;

!pip install package-name

or you could use your python version associated with anaconda

!python3.6 -m pip install package-name

Most likely you need to use this trick:

dbms_output.put_line('Hi' || chr(10) || 
                     'good' || chr(10) || 
                     'morning' || chr(10) || 
                     'friends' || chr(10));

First or all you are using ng-model which is considered to be an angularjs syntax. Use [(ngModel)] instead with the default value

App.component.html

<select [(ngModel)]='nrSelect' class='form-control'>
    <option value='47'>47</option>
    <option value='46'>46</option>
    <option value='45'>45</option>
</select>

App.component.ts

import { Component } from '@angular/core'; 
@Component({ 
    selector: 'my-app', 
    templateUrl: './app.component.html', 
    styleUrls: [ './app.component.css' ] 
}) 

export class AppComponent { 
    nrSelect:string = "47" 
}

New introduction 2

In the previous version of macro "SaveEmailDetails" I used this statement to find Inbox:

Set FolderTgt = CreateObject("Outlook.Application"). _
              GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)

I have since installed a newer version of Outlook and I have discovered that it does not use the default Inbox. For each of my email accounts, it created a separate store (named for the email address) each with its own Inbox. None of those Inboxes is the default.

This macro, outputs the name of the store holding the default Inbox to the Immediate Window:

Sub DsplUsernameOfDefaultStore()

  Dim NS As Outlook.NameSpace
  Dim DefaultInboxFldr As MAPIFolder

  Set NS = CreateObject("Outlook.Application").GetNamespace("MAPI")
  Set DefaultInboxFldr = NS.GetDefaultFolder(olFolderInbox)

  Debug.Print DefaultInboxFldr.Parent.Name

End Sub

On my installation, this outputs: "Outlook Data File".

I have added an extra statement to macro "SaveEmailDetails" that shows how to access the Inbox of any store.

New introduction 1

A number of people have picked up the macro below, found it useful and have contacted me directly for further advice. Following these contacts I have made a few improvements to the macro so I have posted the revised version below. I have also added a pair of macros which together will return the MAPIFolder object for any folder with the Outlook hierarchy. These are useful if you wish to access other than a default folder.

The original text referenced one question by date which linked to an earlier question. The first question has been deleted so the link has been lost. That link was to Update excel sheet based on outlook mail (closed)

Original text

There are a surprising number of variations of the question: "How do I extract data from Outlook emails to Excel workbooks?" For example, two questions up on [outlook-vba] the same question was asked on 13 August. That question references a variation from December that I attempted to answer.

For the December question, I went overboard with a two part answer. The first part was a series of teaching macros that explored the Outlook folder structure and wrote data to text files or Excel workbooks. The second part discussed how to design the extraction process. For this question Siddarth has provided an excellent, succinct answer and then a follow-up to help with the next stage.

What the questioner of every variation appears unable to understand is that showing us what the data looks like on the screen does not tell us what the text or html body looks like. This answer is an attempt to get past that problem.

The macro below is more complicated than Siddarth’s but a lot simpler that those I included in my December answer. There is more that could be added but I think this is enough to start with.

The macro creates a new Excel workbook and outputs selected properties of every email in Inbox to create this worksheet:

Near the top of the macro there is a comment containing eight hashes (#). The statement below that comment must be changed because it identifies the folder in which the Excel workbook will be created.

All other comments containing hashes suggest amendments to adapt the macro to your requirements.

How are the emails from which data is to be extracted identified? Is it the sender, the subject, a string within the body or all of these? The comments provide some help in eliminating uninteresting emails. If I understand the question correctly, an interesting email will have Subject = "Task Completed".

The comments provide no help in extracting data from interesting emails but the worksheet shows both the text and html versions of the email body if they are present. My idea is that you can see what the macro will see and start designing the extraction process.

This is not shown in the screen image above but the macro outputs two versions on the text body. The first version is unchanged which means tab, carriage return, line feed are obeyed and any non-break spaces look like spaces. In the second version, I have replaced these codes with the strings [TB], [CR], [LF] and [NBSP] so they are visible. If my understanding is correct, I would expect to see the following within the second text body:

Activity[TAB]Count[CR][LF]Open[TAB]35[CR][LF]HCQA[TAB]42[CR][LF]HCQC[TAB]60[CR][LF]HAbst[TAB]50 45 5 2 2 1[CR][LF] and so on

Extracting the values from the original of this string should not be difficult.

I would try amending my macro to output the extracted values in addition to the email’s properties. Only when I have successfully achieved this change would I attempt to write the extracted data to an existing workbook. I would also move processed emails to a different folder. I have shown where these changes must be made but give no further help. I will respond to a supplementary question if you get to the point where you need this information.

Good luck.

With Swift 3 and Swift 4, String has a method called data(using:allowLossyConversion:). data(using:allowLossyConversion:) has the following declaration:

func data(using encoding: String.Encoding, allowLossyConversion: Bool = default) -> Data?

Returns a Data containing a representation of the String encoded using a given encoding.

With Swift 4, String's data(using:allowLossyConversion:) can be used in conjunction with JSONDecoder's decode(_:from:) in order to deserialize a JSON string into a dictionary.

Furthermore, with Swift 3 and Swift 4, String's data(using:allowLossyConversion:) can also be used in conjunction with JSONSerialization's json?Object(with:?options:?) in order to deserialize a JSON string into a dictionary.

#1. Swift 4 solution

With Swift 4, JSONDecoder has a method called decode(_:from:). decode(_:from:) has the following declaration:

func decode<T>(_ type: T.Type, from data: Data) throws -> T where T : Decodable

Decodes a top-level value of the given type from the given JSON representation.

The Playground code below shows how to use data(using:allowLossyConversion:) and decode(_:from:) in order to get a Dictionary from a JSON formatted String:

let jsonString = """
{"password" : "1234",  "user" : "andreas"}
"""

if let data = jsonString.data(using: String.Encoding.utf8) {
    do {
        let decoder = JSONDecoder()
        let jsonDictionary = try decoder.decode(Dictionary<String, String>.self, from: data)
        print(jsonDictionary) // prints: ["user": "andreas", "password": "1234"]
    } catch {
        // Handle error
        print(error)
    }
}

#2. Swift 3 and Swift 4 solution

With Swift 3 and Swift 4, JSONSerialization has a method called json?Object(with:?options:?). json?Object(with:?options:?) has the following declaration:

class func jsonObject(with data: Data, options opt: JSONSerialization.ReadingOptions = []) throws -> Any

Returns a Foundation object from given JSON data.

The Playground code below shows how to use data(using:allowLossyConversion:) and json?Object(with:?options:?) in order to get a Dictionary from a JSON formatted String:

import Foundation

let jsonString = "{\"password\" : \"1234\",  \"user\" : \"andreas\"}"

if let data = jsonString.data(using: String.Encoding.utf8) {
    do {
        let jsonDictionary = try JSONSerialization.jsonObject(with: data, options: []) as? [String : String]
        print(String(describing: jsonDictionary)) // prints: Optional(["user": "andreas", "password": "1234"])
    } catch {
        // Handle error
        print(error)
    }
}

player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());

Your version would work if you had only one file in the assets directory. The asset directory contents are not actually 'real files' on disk. All of them are put together one after another. So, if you do not specify where to start and how many bytes to read, the player will read up to the end (that is, will keep playing all the files in assets directory)

As mentioned here: Re: BUG #4243: Idle in transaction it is probably best to check your pg_locks table to see what is being locked and that might give you a better clue where the problem lies.

An answer to your question depends greatly on the size of the integer. Methods for small numbers, e.g. less then 100 bit, and for numbers ~1000 bit (such as used in cryptography) are completely different.

• general overview: http://en.wikipedia.org/wiki/Divisor_function

• values for small n and some useful references: A000005: d(n) (also called tau(n) or sigma_0(n)), the number of divisors of n.

• real-world example: factorization of integers

I needed a way to strip tags and decode HTML entities to plain text. The following solution is based on Eloff's answer (which I couldn't use because it strips entities).

from HTMLParser import HTMLParser
import htmlentitydefs

class HTMLTextExtractor(HTMLParser):
    def __init__(self):
        HTMLParser.__init__(self)
        self.result = [ ]

    def handle_data(self, d):
        self.result.append(d)

    def handle_charref(self, number):
        codepoint = int(number[1:], 16) if number[0] in (u'x', u'X') else int(number)
        self.result.append(unichr(codepoint))

    def handle_entityref(self, name):
        codepoint = htmlentitydefs.name2codepoint[name]
        self.result.append(unichr(codepoint))

    def get_text(self):
        return u''.join(self.result)

def html_to_text(html):
    s = HTMLTextExtractor()
    s.feed(html)
    return s.get_text()

A quick test:

html = u'<a href="#">Demo <em>(&not; \u0394&#x03b7;&#956;&#x03CE;)</em></a>'
print repr(html_to_text(html))

Result:

u'Demo (\xac \u0394\u03b7\u03bc\u03ce)'

Error handling:

• Invalid HTML structure may cause an HTMLParseError.
• Invalid named HTML entities (such as &#apos;, which is valid in XML and XHTML, but not plain HTML) will cause a ValueError exception.
• Numeric HTML entities specifying code points outside the Unicode range acceptable by Python (such as, on some systems, characters outside the Basic Multilingual Plane) will cause a ValueError exception.

Security note: Do not confuse HTML stripping (converting HTML into plain text) with HTML sanitizing (converting plain text into HTML). This answer will remove HTML and decode entities into plain text – that does not make the result safe to use in a HTML context.

Example: <script>alert("Hello");</script> will be converted to <script>alert("Hello");</script>, which is 100% correct behavior, but obviously not sufficient if the resulting plain text is inserted as-is into a HTML page.

The rule is not hard: Any time you insert a plain-text string into HTML output, you should always HTML escape it (using cgi.escape(s, True)), even if you "know" that it doesn't contain HTML (e.g. because you stripped HTML content).

(However, the OP asked about printing the result to the console, in which case no HTML escaping is needed.)

Python 3.4+ version: (with doctest!)

import html.parser

class HTMLTextExtractor(html.parser.HTMLParser):
    def __init__(self):
        super(HTMLTextExtractor, self).__init__()
        self.result = [ ]

    def handle_data(self, d):
        self.result.append(d)

    def get_text(self):
        return ''.join(self.result)

def html_to_text(html):
    """Converts HTML to plain text (stripping tags and converting entities).
    >>> html_to_text('<a href="#">Demo<!--...--> <em>(&not; \u0394&#x03b7;&#956;&#x03CE;)</em></a>')
    'Demo (\xac \u0394\u03b7\u03bc\u03ce)'

    "Plain text" doesn't mean result can safely be used as-is in HTML.
    >>> html_to_text('&lt;script&gt;alert("Hello");&lt;/script&gt;')
    '<script>alert("Hello");</script>'

    Always use html.escape to sanitize text before using in an HTML context!

    HTMLParser will do its best to make sense of invalid HTML.
    >>> html_to_text('x < y &lt z <!--b')
    'x < y < z '

    Unrecognized named entities are included as-is. '&apos;' is recognized,
    despite being XML only.
    >>> html_to_text('&nosuchentity; &apos; ')
    "&nosuchentity; ' "
    """
    s = HTMLTextExtractor()
    s.feed(html)
    return s.get_text()

Note that HTMLParser has improved in Python 3 (meaning less code and better error handling).

Loading the values in an array would be much faster:

Dim data(), dict As Object, r As Long
Set dict = CreateObject("Scripting.Dictionary")

data = ActiveSheet.UsedRange.Columns(1).Value

For r = 1 To UBound(data)
    dict(data(r, some_column_number)) = Empty
Next

data = WorksheetFunction.Transpose(dict.keys())

You should also consider early binding for the Scripting.Dictionary:

Dim dict As New Scripting.Dictionary  ' requires `Microsoft Scripting Runtime` '

Note that using a dictionary is way faster than Range.AdvancedFilter on large data sets.

As a bonus, here's a procedure similare to Range.RemoveDuplicates to remove duplicates from a 2D array:

Public Sub RemoveDuplicates(data, ParamArray columns())
    Dim ret(), indexes(), ids(), r As Long, c As Long
    Dim dict As New Scripting.Dictionary  ' requires `Microsoft Scripting Runtime` '

    If VarType(data) And vbArray Then Else Err.Raise 5, , "Argument data is not an array"

    ReDim ids(LBound(columns) To UBound(columns))

    For r = LBound(data) To UBound(data)         ' each row '
        For c = LBound(columns) To UBound(columns)   ' each column '
            ids(c) = data(r, columns(c))                ' build id for the row
        Next
        dict(Join$(ids, ChrW(-1))) = r  ' associate the row index to the id '
    Next

    indexes = dict.Items()
    ReDim ret(LBound(data) To LBound(data) + dict.Count - 1, LBound(data, 2) To UBound(data, 2))

    For c = LBound(ret, 2) To UBound(ret, 2)  ' each column '
        For r = LBound(ret) To UBound(ret)      ' each row / unique id '
            ret(r, c) = data(indexes(r - 1), c)   ' copy the value at index '
        Next
    Next

    data = ret
End Sub

With quotes:

cat /etc/*-release | grep "PRETTY_NAME" | sed 's/PRETTY_NAME=//g'

gives output as:

"CentOS Linux 7 (Core)"

Without quotes:

cat /etc/*-release | grep "PRETTY_NAME" | sed 's/PRETTY_NAME=//g' | sed 's/"//g'

gives output as:

CentOS Linux 7 (Core)

This answer is an update with a little more consideration for OOM and various other leaks.

Assumes you have a directory intended as the destination and a name String already defined.

    File destination = new File(directory.getPath() + File.separatorChar + filename);

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    source.compress(Bitmap.CompressFormat.PNG, 100, bytes);

    FileOutputStream fo = null;
    try {
        destination.createNewFile();

        fo = new FileOutputStream(destination);
        fo.write(bytes.toByteArray());
    } catch (IOException e) {

    } finally {
        try {
            fo.close();
        } catch (IOException e) {}
    }

The backslash \ is the escape character for regular expressions. Therefore a double backslash would indeed mean a single, literal backslash.

\ (backslash) followed by any of [\^$.|?*+(){} escapes the special character to suppress its special meaning.

ref : http://www.regular-expressions.info/reference.html

This may be used in many other scenarios, where you need to copy only a portion of your original string to the destination. Using strncpy() you can copy a limited portion of the original string as opposed by strcpy(). I see the code you have put up comes from publib.boulder.ibm.com.

Something like this:

=FormatDateTime(Now, DateFormat.ShortDate) 

Where "Now" can be replaced by the name of the date/time field that you're trying to convert.)
For instance,

=FormatDateTime(Fields!StartDate.Value, DateFormat.ShortDate)

For development you can use https://cors-anywhere.herokuapp.com , for production is better to set up your own proxy

async function read() {_x000D_
   let r= await (await fetch('https://cors-anywhere.herokuapp.com/http://ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&q=http://feeds.feedburner.com/mathrubhumi')).json();_x000D_
   console.log(r);_x000D_
}_x000D_
_x000D_
read();

In a special case within ASP.NET If you want to know if the page is redirected by a specified .aspx page and not another one, just put the information in a session name and take necessary action in the receiving Page_Load Event.

Here is what I came up with. I was having major problems with this and believe I am in MVC 6 now but this may be helpful to someone even myself in the future..

//The issue was that Reqest.Form Request.Querystring and Request not working in MVC the solution is to use Context.Request.Form and also making sure the form has been submitted otherwise null reference or context issue bug will show up.

     if(Context.Request.ContentLength != null)
     {
         String StartDate = Context.Request.Form["StartMonth"].ToString();
         String EndMonth = Context.Request.Form["EndMonth"].ToString();
        // Vendor

     }

This works too and you dont have to use join or anything:

DROP VIEW IF EXISTS yourview;

CREATE VIEW yourview AS
    SELECT table1.column1, 
    table2.column2
FROM 
table1, table2 
WHERE table1.column1 = table2.column1;

This might be new in 5.7, but there is now an options array to the auth method. Simply changing

Auth::routes();

to

Auth::routes(['register' => false]);

in your routes file after running php artisan make:auth will disable user registration.

In Bootstrap 4 it was renamed to .rounded-circle

Usage :

<div class="col-xs-7">
    <img src="img/gallery2.JPG" class="rounded-circle" alt="HelPic>
</div>

See migration docs from bootstrap.

Its possible to do silent install on Android 6 and above. Using the function supplied in the answer by Boris Treukhov, ignore everything else in the post, root is not required either.

Install your app as device admin, you can have full kiosk mode with silent install of updates in the background.

Using exc_info options may be better, to allow you to choose the error level (if you use exception, it will always be at the error level):

try:
    # do something here
except Exception as e:
    logging.critical(e, exc_info=True)  # log exception info at CRITICAL log level

I don't believe it's possible with Bash's builtin functionality.

You can get notification when a child exits:

#!/bin/sh
set -o monitor        # enable script job control
trap 'echo "child died"' CHLD

However there's no apparent way to get the child's exit status in the signal handler.

Getting that child status is usually the job of the wait family of functions in the lower level POSIX APIs. Unfortunately Bash's support for that is limited - you can wait for one specific child process (and get its exit status) or you can wait for all of them, and always get a 0 result.

What it appears impossible to do is the equivalent of waitpid(-1), which blocks until any child process returns.

Been using this in production for some time now without any complaints (May take some tweaking to look right on your site.. for instance, subtracting the width of a sidebar, etc)

$(window).bind('resize', function() {
    $("#jqgrid").setGridWidth($(window).width());
}).trigger('resize');

value = (int)(value * 100 + 0.5) / 100.0;

Your code is failing on this line:

var RUnits = Math.abs(document.all.Capacity.RUnits.value);

i tried stepping though it with firebug and it fails there. that should help you figure out the problem.

you have jquery referenced. you might as well use it in all these functions. it'll clean up your code significantly.

Window: conda activate environment_name

Mac: conda activate environment_name

You can hide it :

html {
  overflow:   scroll;
}
::-webkit-scrollbar {
    width: 0px;
    background: transparent; /* make scrollbar transparent */
}

For further information, see : Hide scroll bar, but while still being able to scroll

The difference between getAttribute and getParameter is that getParameter will return the value of a parameter that was submitted by an HTML form or that was included in a query string. getAttribute returns an object that you have set in the request, the only way you can use this is in conjunction with a RequestDispatcher. You use a RequestDispatcher to forward a request to another resource (JSP / Servlet). So before you forward the request you can set an attribute which will be available to the next resource.

A further twist to the excellent answer from @Jan is to incorporate this into the #uberbar fixed header, which uses jQuery (or MooTools). (http://davidwalsh.name/persistent-header-opacity)

I've tweaked the code so the the top of the content is always below not under the fixed header and also added the anchors from @Jan again making sure that the anchors are always positioned below the fixed header.

The CSS:

#uberbar { 
    border-bottom:1px solid #0000cc; 
    position:fixed; 
    top:0; 
    left:0; 
    z-index:2000; 
    width:100%;
}

a.anchor {
    display: block;
    position: relative;
    visibility: hidden;
}

The jQuery (including tweaks to both the #uberbar and the anchor approaches:

<script type="text/javascript">
$(document).ready(function() {
    (function() {
        //settings
        var fadeSpeed = 200, fadeTo = 0.85, topDistance = 30;
        var topbarME = function() { $('#uberbar').fadeTo(fadeSpeed,1); }, topbarML = function() { $('#uberbar').fadeTo(fadeSpeed,fadeTo); };
        var inside = false;
        //do
        $(window).scroll(function() {
            position = $(window).scrollTop();
            if(position > topDistance && !inside) {
                //add events
                topbarML();
                $('#uberbar').bind('mouseenter',topbarME);
                $('#uberbar').bind('mouseleave',topbarML);
                inside = true;
            }
            else if (position < topDistance){
                topbarME();
                $('#uberbar').unbind('mouseenter',topbarME);
                $('#uberbar').unbind('mouseleave',topbarML);
                inside = false;
            }
        });
        $('#content').css({'margin-top': $('#uberbar').outerHeight(true)});
        $('a.anchor').css({'top': - $('#uberbar').outerHeight(true)});
    })();
});
</script>

And finally the HTML:

<div id="uberbar">
    <!--CONTENT OF FIXED HEADER-->
</div>
....
<div id="content">
    <!--MAIN CONTENT-->
    ....
    <a class="anchor" id="anchor1"></a>
    ....
    <a class="anchor" id="anchor2"></a>
    ....
</div>

Maybe this is useful to somebody who likes the #uberbar fading dixed header!

I want to put the correct answer in here, just in case others are having this problem like I was. If you hate the ViewBag, fine don't use it, but the real problem with the code in the question is that the same name is being used for both the model property and the selectlist as was pointed out by @RickAndMSFT

Simply changing the name of the DropDownList control should resolve the issue, like so:

@Html.DropDownList("NewsCategoriesSelection", (SelectList)ViewBag.NewsCategoriesID)

It doesn't really have anything to do with using the ViewBag or not using the ViewBag as you can have a name collision with the control regardless.

Without opening Xcode:

open /Applications/Xcode.app/Contents/Developer/Applications/iOS\ Simulator.app/

SELECT DATABASE();

p.s. I didn't want to take the liberty of modifying @cwallenpoole's answer to reflect the fact that this is a MySQL question and not an Oracle question and doesn't need DUAL.

Ok, I know this already has a highly upvoted answer, but another similar question was asked recently, and I was directed to this question as well. I'd like to offer my solution as well, because it offers an advantage over the accepted solution: You can include disabled form elements (which is sometimes important, depending on how your UI functions)

Here is my answer from the other SO question:

Initially, we were using jQuery's serializeArray() method, but that does not include form elements that are disabled. We will often disable form elements that are "sync'd" to other sources on the page, but we still need to include the data in our serialized object. So serializeArray() is out. We used the :input selector to get all input elements (both enabled and disabled) in a given container, and then $.map() to create our object.

var inputs = $("#container :input");
var obj = $.map(inputs, function(n, i)
{
    var o = {};
    o[n.name] = $(n).val();
    return o;
});
console.log(obj);

Note that for this to work, each of your inputs will need a name attribute, which will be the name of the property of the resulting object.

That is actually slightly modified from what we used. We needed to create an object that was structured as a .NET IDictionary, so we used this: (I provide it here in case it's useful)

var obj = $.map(inputs, function(n, i)
{
    return { Key: n.name, Value: $(n).val() };
});
console.log(obj);

I like both of these solutions, because they are simple uses of the $.map() function, and you have complete control over your selector (so, which elements you end up including in your resulting object). Also, no extra plugin required. Plain old jQuery.

To reduce memory consumption and to speed up the search you may use -ReadCount option of Get-Content cmdlet (https://technet.microsoft.com/ru-ru/library/hh849787.aspx).

This may save hours when you working with large files.

Here is an example:

$n = 60699010
$src = 'hugefile.csv'
$batch = 100
$timer = [Diagnostics.Stopwatch]::StartNew()

$count = 0
Get-Content $src -ReadCount $batch -TotalCount $n | %  { 
    $count += $_.Length
    if ($count -ge $n ) {
        $_[($n - $count + $_.Length - 1)]
    }
}

$timer.Stop()
$timer.Elapsed

This prints $n'th line and elapsed time.

Update: Chrome 58+ hid these and other debug messages by default. To display them click the arrow next to 'Info' and select 'Verbose'.

Chrome 57 turned on 'hide violations' by default. To turn them back on you need to enable filters and uncheck the 'hide violations' box.

suddenly it appears when someone else involved in the project

I think it's more likely you updated to Chrome 56. This warning is a wonderful new feature, in my opinion, please only turn it off if you're desperate and your assessor will take marks away from you. The underlying problems are there in the other browsers but the browsers just aren't telling you there's a problem. The Chromium ticket is here but there isn't really any interesting discussion on it.

These messages are warnings instead of errors because it's not really going to cause major problems. It may cause frames to get dropped or otherwise cause a less smooth experience.

They're worth investigating and fixing to improve the quality of your application however. The way to do this is by paying attention to what circumstances the messages appear, and doing performance testing to narrow down where the issue is occurring. The simplest way to start performance testing is to insert some code like this:

function someMethodIThinkMightBeSlow() {
    const startTime = performance.now();

    // Do the normal stuff for this function

    const duration = performance.now() - startTime;
    console.log(`someMethodIThinkMightBeSlow took ${duration}ms`);
}

If you want to get more advanced, you could also use Chrome's profiler, or make use of a benchmarking library like this one.

Once you've found some code that's taking a long time (50ms is Chrome's threshold), you have a couple of options:

1. Cut out some/all of that task that may be unnecessary
2. Figure out how to do the same task faster
3. Divide the code into multiple asynchronous steps

(1) and (2) may be difficult or impossible, but it's sometimes really easy and should be your first attempts. If needed, it should always be possible to do (3). To do this you will use something like:

setTimeout(functionToRunVerySoonButNotNow);

or

// This one is not available natively in IE, but there are polyfills available.
Promise.resolve().then(functionToRunVerySoonButNotNow);

You can read more about the asynchronous nature of JavaScript here.

I was able to solve the same issue by setting the timezone in my linux system (Centos6.5).

Reposting from

http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-time.html

1. set timezone in /etc/sysconfig/clock e.g. set to ZONE="America/Los_Angeles"

2. sudo ln -sf /usr/share/zoneinfo/America/Phoenix /etc/localtime

To figure out the timezone value try to

ls /usr/share/zoneinfo

and look for the file that represents your timezone.

Once you've set these reboot the machine and try again.

You could get the keys of the array before the foreach, then use a counter to check the next element, something like:

//$arr is the array you wish to cycle through
$keys = array_keys($arr);
$num_keys = count($keys);
$i = 1;
foreach ($arr as $a)
{
    if ($i < $num_keys && $arr[$keys[$i]] == $a)
    {
        // we have a match
    }
    $i++;
}

This will work for both simple arrays, such as array(1,2,3), and keyed arrays such as array('first'=>1, 'second'=>2, 'thrid'=>3).

It is possible by recreating table.Its work for me please follow following step:

1. create temporary table using as select * from your table
2. drop your table, create your table using modify column type
3. now insert records from temp table to your newly created table
4. drop temporary table

do all above steps in worker thread to reduce load on uithread

It's called models.Model and not models.model (case sensitive). Fix your Poll model like this -

class Poll(models.Model):
    question = models.CharField(max_length=200) 
    pub_date = models.DateTimeField('date published')

String currentString = "Fruit: they taste good";
String[] separated = currentString.split(":");
separated[0]; // this will contain "Fruit"
separated[1]; // this will contain " they taste good"

You may want to remove the space to the second String:

separated[1] = separated[1].trim();

If you want to split the string with a special character like dot(.) you should use escape character \ before the dot

Example:

String currentString = "Fruit: they taste good.very nice actually";
String[] separated = currentString.split("\\.");
separated[0]; // this will contain "Fruit: they taste good"
separated[1]; // this will contain "very nice actually"

There are other ways to do it. For instance, you can use the StringTokenizer class (from java.util):

StringTokenizer tokens = new StringTokenizer(currentString, ":");
String first = tokens.nextToken();// this will contain "Fruit"
String second = tokens.nextToken();// this will contain " they taste good"
// in the case above I assumed the string has always that syntax (foo: bar)
// but you may want to check if there are tokens or not using the hasMoreTokens method

Bash supports a concept called "Positional Parameters". These positional parameters represent arguments that are specified on the command line when a Bash script is invoked.

Positional parameters are referred to by the names $0, $1, $2 ... and so on. $0 is the name of the script itself, $1 is the first argument to the script, $2 the second, etc. $* represents all of the positional parameters, except for $0 (i.e. starting with $1).

An example:

#!/bin/bash
FILE="$1"
externalprogram "$FILE" <other-parameters>

You almost never want to use Read Uncommited since it's not really ACID compliant. Read Commmited is a good default starting place. Repeatable Read is probably only needed in reporting, rollup or aggregation scenarios. Note that many DBs, postgres included don't actually support Repeatable Read, you have to use Serializable instead. Serializable is useful for things that you know have to happen completely independently of anything else; think of it like synchronized in Java. Serializable goes hand in hand with REQUIRES_NEW propagation.

I use REQUIRES for all functions that run UPDATE or DELETE queries as well as "service" level functions. For DAO level functions that only run SELECTs, I use SUPPORTS which will participate in a TX if one is already started (i.e. being called from a service function).

Global $myArr;
$myArr = array();

function someFuntion(){
    global $myArr;

    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
}

Be forewarned, generally people stick away from globals as it has some downsides.

You could try this

function someFuntion($myArr){
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
    return $myArr;
}
$myArr = someFunction($myArr);

That would make it so you aren't relying on Globals.

ints:

$query = "SELECT * FROM `$table` WHERE `$column` IN(".implode(',',$array).")";

strings:

$query = "SELECT * FROM `$table` WHERE `$column` IN('".implode("','",$array)."')";

Make sure the Excel file isn't open.

Use textContent instead of value to set the button text.

Typically the value attribute is used to associate a value with the button when it's submitted as form data.

Note that while it's possible to set the button text with innerHTML, using textContext should be preferred because it's more performant and it can prevent cross-site scripting attacks as its value is not parsed as HTML.

JS:

var b = document.createElement('button');
b.setAttribute('content', 'test content');
b.setAttribute('class', 'btn');  
b.textContent = 'test value';

var wrapper = document.getElementById("divWrapper");
wrapper.appendChild(b);

Produces this in the DOM:

<div id="divWrapper">
    <button content="test content" class="btn">test value</button>
</div>

The value of the certificate comes mostly from the trust of the internet users in the issuer of the certificate. To that end, Verisign is tough to beat. A certificate says to the client that you are who you say you are, and the issuer has verified that to be true.

You can get a free SSL certificate signed, for example, by StartSSL. This is an improvement on self-signed certificates, because your end-users would stop getting warning pop-ups informing them of a suspicious certificate on your end. However, the browser bar is not going to turn green when communicating with your site over https, so this solution is not ideal.

The cheapest SSL certificate that turns the bar green will cost you a few hundred dollars, and you would need to go through a process of proving the identity of your company to the issuer of the certificate by submitting relevant documents.

With C++-11 or Boost libs you could consider storing the variable using smart pointers. Consider this MVE where toString() behaviour depends on bar being initialized or not:

#include <memory>
#include <sstream>

class Foo {

private:
    std::shared_ptr<int> bar;

public:
    Foo() {}
    void setBar(int bar) {
        this->bar = std::make_shared<int>(bar);
    }
    std::string toString() const {
        std::ostringstream ss;
        if (bar)           // bar was set
            ss << *bar;
        else               // bar was never set
            ss << "unset";
        return ss.str();
    }
};

Using this code

Foo f;
std::cout << f.toString() << std::endl;
f.setBar(42);
std::cout << f.toString() << std::endl;

produces the output

unset
42

I think the problem can be because of the NAT. Normally the DNS clients make requests via UDP. But when the DNS server is behind the NAT the UDP requests will not work.

You could declare a variable as a temporary table like this:

declare @myList table (Id int)

Which means you can use the insert statement to populate it with values:

insert into @myList values (1), (2), (5), (7), (10)

Then your select statement can use either the in statement:

select * from DBTable
where id in (select Id from @myList)

Or you could join to the temporary table like this:

select *
from DBTable d
join @myList t on t.Id = d.Id

And if you do something like this a lot then you could consider defining a user-defined table type so you could then declare your variable like this:

declare @myList dbo.MyTableType

It sounds like you can pick and choose. If you pick float, you may lose 11 digits of precision. If that's acceptable, go for it -- apparently the Linq designers thought this to be a good tradeoff.

However, if your application needs those extra digits, use decimal. Decimal (implemented correctly) is way more accurate than a float anyway -- no messy translation from base 10 to base 2 and back.

Nope, it is more complicated than just calling a method, if you want to transparently add it into the user's calendar.

You've got a couple of choices;

1. Calling the intent to add an event on the calendar
   This will pop up the Calendar application and let the user add the event. You can pass some parameters to prepopulate fields:

   Calendar cal = Calendar.getInstance();              
   Intent intent = new Intent(Intent.ACTION_EDIT);
   intent.setType("vnd.android.cursor.item/event");
   intent.putExtra("beginTime", cal.getTimeInMillis());
   intent.putExtra("allDay", false);
   intent.putExtra("rrule", "FREQ=DAILY");
   intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
   intent.putExtra("title", "A Test Event from android app");
   startActivity(intent);
   

   Or the more complicated one:

2. Get a reference to the calendar with this method
   (It is highly recommended not to use this method, because it could break on newer Android versions):

   private String getCalendarUriBase(Activity act) {
   
       String calendarUriBase = null;
       Uri calendars = Uri.parse("content://calendar/calendars");
       Cursor managedCursor = null;
       try {
           managedCursor = act.managedQuery(calendars, null, null, null, null);
       } catch (Exception e) {
       }
       if (managedCursor != null) {
           calendarUriBase = "content://calendar/";
       } else {
           calendars = Uri.parse("content://com.android.calendar/calendars");
           try {
               managedCursor = act.managedQuery(calendars, null, null, null, null);
           } catch (Exception e) {
           }
           if (managedCursor != null) {
               calendarUriBase = "content://com.android.calendar/";
           }
       }
       return calendarUriBase;
   }
   

   and add an event and a reminder this way:

   // get calendar
   Calendar cal = Calendar.getInstance();     
   Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
   ContentResolver cr = getContentResolver();
   
   // event insert
   ContentValues values = new ContentValues();
   values.put("calendar_id", 1);
   values.put("title", "Reminder Title");
   values.put("allDay", 0);
   values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
   values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
   values.put("description", "Reminder description");
   values.put("visibility", 0);
   values.put("hasAlarm", 1);
   Uri event = cr.insert(EVENTS_URI, values);
   
   // reminder insert
   Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
   values = new ContentValues();
   values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
   values.put( "method", 1 );
   values.put( "minutes", 10 );
   cr.insert( REMINDERS_URI, values );
   

   You'll also need to add these permissions to your manifest for this method:

   <uses-permission android:name="android.permission.READ_CALENDAR" />
   <uses-permission android:name="android.permission.WRITE_CALENDAR" />
   

Update: ICS Issues

The above examples use the undocumented Calendar APIs, new public Calendar APIs have been released for ICS, so for this reason, to target new android versions you should use CalendarContract.

More infos about this can be found at this blog post.

In Java, when you type a decimal number as 3.6, its interpreted as a double. double is a 64-bit precision IEEE 754 floating point, while floatis a 32-bit precision IEEE 754 floating point. As a float is less precise than a double, the conversion cannot be performed implicitly.

If you want to create a float, you should end your number with f (i.e.: 3.6f).

For more explanation, see the primitive data types definition of the Java tutorial.

Add the following to your on button click event:

Intent intent = new Intent(First.this, Second.class);
startActivity(intent);
finish();

There is a setting window.zoom that can enlarge the entire window content including the top menus and side nav tree. Setting this to 1 on a 4k monitor makes the content similar to a 1080p monitor of the same physical size.

You are disabling only on document.ready and this happens only once when DOM is ready but you need to disable in keyup event too when textbox gets empty. Also change $(this).val.length to $(this).val().length

$(document).ready(function(){
    $('.sendButton').attr('disabled',true);
    $('#message').keyup(function(){
        if($(this).val().length !=0)
            $('.sendButton').attr('disabled', false);            
        else
            $('.sendButton').attr('disabled',true);
    })
});

Or you can use conditional operator instead of if statement. also use prop instead of attr as attribute is not recommended by jQuery 1.6 and above for disabled, checked etc.

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method, jQuery docs

$(document).ready(function(){
    $('.sendButton').prop('disabled',true);
    $('#message').keyup(function(){
        $('.sendButton').prop('disabled', this.value == "" ? true : false);     
    })
});  

I am a slow learner of javascript promises, by default all async functions return a promise, you can wrap your result as:

(async () => {
//Optional "await"
  await yourAsyncFunctionOrPromise()
    .then(function (result) {
      return result +1;
    })
    .catch(function (error) {
      return error;
    })()
})

"The await expression causes async function execution to pause until a Promise is settled (that is, fulfilled or rejected), and to resume execution of the async function after fulfillment. When resumed, the value of the await expression is that of the fulfilled Promise. If the Promise is rejected, the await expression throws the rejected value."

Read more about await and promises at MDN Web Docs

Inconsolata (http://www.levien.com/type/myfonts/inconsolata.html) is a great monospaced font for programming. Earlier versions tend to act weird on OS X, but the newer versions work out very well.

This works for PL/SQL:

select count(*), id,address from table group by id,address having count(*)<2

Lexical (AKA static) scoping refers to determining a variable's scope based solely on its position within the textual corpus of code. A variable always refers to its top-level environment. It's good to understand it in relation to dynamic scope.

There is a calc function in both SCSS [compile-time] and CSS [run-time]. You're likely invoking the former instead of the latter.

For obvious reasons mixing units won't work compile-time, but will at run-time.

You can force the latter by using unquote, a SCSS function.

.selector { height: unquote("-webkit-calc(100% - 40px)"); }

What output (exactly) does dir myfile.txt give in the current directory? What happens if you set the delimiters?

FOR /f "tokens=1,2* delims= " %%a in ('dir myfile.txt^|find /i " myfile.txt"') DO SET fileDate=%%a 

(note the space after delims=)
(to make life easier, you can do this from the command line by replacing %%a with %a)

You don't.

If you want to extend Person with Student, just do:

public class Student extends Person
{
}

And make sure, when you compile both classes, one can find the other one.

What IDE are you using?

For any number validation you have to use different different range validation as per your requirements :

For Integer

[Range(0, int.MaxValue, ErrorMessage = "Please enter valid integer Number")]

for float

[Range(0, float.MaxValue, ErrorMessage = "Please enter valid float Number")]

for double

[Range(0, double.MaxValue, ErrorMessage = "Please enter valid doubleNumber")]

The solution that for me works is:

For Each xCell In Selection

  xCell.Value = CDec(xCell.Value)

Next xCell 

I figured it out that x.view(-1, 16 * 5 * 5) is equivalent to x.flatten(1), where the parameter 1 indicates the flatten process starts from the 1st dimension(not flattening the 'sample' dimension) As you can see, the latter usage is semantically more clear and easier to use, so I prefer flatten().

The solution has to do with the fact that your the file holding your php configurations. i.e php.ini has uncommented the extension responsible for acting as the middleman between php and postgres, by placing a ";" in front of the statement "extension=pdo_pgsql"

Quick Fix

1. Open the php.ini file in your favourite editor. (atom )
2. Search for the line "extension=pdo_pgsql", which is under the "Dynamic Extensions" section. (a simple ctrl + f) would get you there quick.
3. Remove the ";" in front of the line ";extension=pdo_pgsql".
4. Restart your server.
5. Go fix more errors like a rock star.

If you are going to call relative.py directly and i.e. if you really want to import from a top level module you have to explicitly add it to the sys.path list.
Here is how it should work:

# Add this line to the beginning of relative.py file
import sys
sys.path.append('..')

# Now you can do imports from one directory top cause it is in the sys.path
import parent

# And even like this:
from parent import Parent

If you think the above can cause some kind of inconsistency you can use this instead:

sys.path.append(sys.path[0] + "/..")

sys.path[0] refers to the path that the entry point was ran from.

If all that you need is details of User, for Spring Version 4.x you can use @AuthenticationPrincipal and @EnableWebSecurity tag provided by Spring as shown below.

Security Configuration Class:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
   ...
}

Controller method:

@RequestMapping("/messages/inbox")
public ModelAndView findMessagesForUser(@AuthenticationPrincipal User user) {
    ...
}

public class BOX
{
    double height, length, breadth;

    public static bool operator == (BOX b1, BOX b2)
    {
        if (b1 is null)
            return b2 is null;

        return b1.Equals(b2);
    }

    public static bool operator != (BOX b1, BOX b2)
    {
        return !(b1 == b2);
    }

    public override bool Equals(object obj)
    {
        if (obj == null)
            return false;

        return obj is BOX b2? (length == b2.length && 
                               breadth == b2.breadth && 
                               height == b2.height): false;

    }

    public override int GetHashCode()
    {
        return (height,length,breadth).GetHashCode();
    }
}

Be consistent with the API(s) you're using.

Using @DrunkenDaddy extension function, in my case at least (creating EditText programmatically), it was displaying the keyboard on first click and then the date picker on second click.

Apparently, it's irrelevant to set isFocusable and isFocusableInTouchMode to false, because first click is always interpreted as a focus change by the EditText. So I had to trigger a click when the EditText gained focus. Now it works as expected: on first click it opens directly the date picker and never the keyboard (thanks to setting showSoftInputOnFocus to false):

fun EditText.transformIntoDatePicker(context: Context, format: String = "dd/MM/yyyy", maxDate: Date? = null) {
    isClickable = true
    showSoftInputOnFocus = false
    isCursorVisible = false

    setOnFocusChangeListener { _, hasFocus ->  if (hasFocus) callOnClick()}

    val myCalendar = Calendar.getInstance()
    val datePickerOnDataSetListener =
        DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
            val sdf = SimpleDateFormat(format, Locale.getDefault())
            setText(sdf.format(myCalendar.time))
    }

    setOnClickListener {
        DatePickerDialog(
             context, datePickerOnDataSetListener, 
             myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
             myCalendar.get(Calendar.DAY_OF_MONTH)
        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
    }
}

You could create a CSS class for this and apply it to your columns. Since the gutter (spacing between columns) is controlled by padding in Bootstrap 3, adjust the padding accordingly:

.col {
  padding-right:7px;
  padding-left:7px;
}

Demo: http://bootply.com/93473

EDIT If you only want the spacing between columns you can select all cols except first and last like this..

.col:not(:first-child,:last-child) {
  padding-right:7px;
  padding-left:7px;
}

Updated Bootply

For Bootstrap 4 see: Remove gutter space for a specific div only

Aah you just need to add a name parameter in the

FileBody constructor. ContentBody cbFile = new FileBody(file, "image/jpeg", "FILE_NAME");

Hope it helps.

array_slice returns a slice of an array

$sliced_array = array_slice($array, 0, 5)

is the code you want in your case to return the first five elements

If you know all the data is just a single word here's a solution. First update the column to all lower and then run the following

    update tableName set columnName = 
    upper(SUBSTRING(columnName, 1, 1)) + substring(columnName, 2, len(columnName)) from tableName

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

Your error

Notice: Trying to get property of non-object in C:\wamp\www\phone\pages\init.php on line 22

Your comment

@22 is <?php echo $sidemenu->mname."<br />";?>

$sidemenu is not an object, and you are trying to access one of its properties.

That is the reason for your error.

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

Python can use all memory available to its environment. My simple "memory test" crashes on ActiveState Python 2.6 after using about

1959167 [MiB]

On jython 2.5 it crashes earlier:

 239000 [MiB]

probably I can configure Jython to use more memory (it uses limits from JVM)

Test app:

import sys

sl = []
i = 0
# some magic 1024 - overhead of string object
fill_size = 1024
if sys.version.startswith('2.7'):
    fill_size = 1003
if sys.version.startswith('3'):
    fill_size = 497
print(fill_size)
MiB = 0
while True:
    s = str(i).zfill(fill_size)
    sl.append(s)
    if i == 0:
        try:
            sys.stderr.write('size of one string %d\n' % (sys.getsizeof(s)))
        except AttributeError:
            pass
    i += 1
    if i % 1024 == 0:
        MiB += 1
        if MiB % 25 == 0:
            sys.stderr.write('%d [MiB]\n' % (MiB))

In your app you read whole file at once. For such big files you should read the line by line.
