The pure javascript solution is better, but a jQuery way would be to use the jQuery grep and/or map methods. Probably not much better than using $.each

jQuery.grep(TestObj, function(obj) {
    return obj.id === "A";
});

or

jQuery.map(TestObj, function(obj) {
    if(obj.id === "A")
         return obj; // or return obj.name, whatever.
});

Returns an array of the matching objects, or of the looked-up values in the case of map. Might be able to do what you want simply using those.

But in this example you'd have to do some recursion, because the data isn't a flat array, and we're accepting arbitrary structures, keys, and values, just like the pure javascript solutions do.

function getObjects(obj, key, val) {
    var retv = [];

    if(jQuery.isPlainObject(obj))
    {
        if(obj[key] === val) // may want to add obj.hasOwnProperty(key) here.
            retv.push(obj);

        var objects = jQuery.grep(obj, function(elem) {
            return (jQuery.isArray(elem) || jQuery.isPlainObject(elem));
        });

        retv.concat(jQuery.map(objects, function(elem){
            return getObjects(elem, key, val);
        }));
    }

    return retv;
}

Essentially the same as Box9's answer, but using the jQuery utility functions where useful.

As has been pointed out in a couple of other answers, the preferred method now is NOT to use smartindent, but instead use the following (in your .vimrc):

filetype plugin indent on
" show existing tab with 4 spaces width
set tabstop=4
" when indenting with '>', use 4 spaces width
set shiftwidth=4
" On pressing tab, insert 4 spaces
set expandtab

set smartindent
set tabstop=4
set shiftwidth=4
set expandtab

:help smartindent

:help auto-setting

:set all

:help C-indenting

Answering to myself. From the RequireJS website:

//THIS WILL FAIL
define(['require'], function (require) {
    var namedModule = require('name');
});

This fails because requirejs needs to be sure to load and execute all dependencies before calling the factory function above. [...] So, either do not pass in the dependency array, or if using the dependency array, list all the dependencies in it.

My solution:

// Modules configuration (modules that will be used as Jade helpers)
define(function () {
    return {
        'moment':   'path/to/moment',
        'filesize': 'path/to/filesize',
        '_':        'path/to/lodash',
        '_s':       'path/to/underscore.string'
    };
});

The loader:

define(['jade', 'lodash', 'config'], function (Jade, _, Config) {
    var deps;

    // Dynamic require
    require(_.values(Config), function () {
        deps = _.object(_.keys(Config), arguments);

        // Use deps...
    });
});

I don't think the speech bubble is quite right. I tweaked it a bit so that it would work and the item opens right under the link.

function PositionDialog(link) {
    $('#myDialog').dialog('open');
    var myDialogX = $(link).position().left;
    var myDialogY = $(link).position().top + $(link).outerHeight();
    $('#myDialog').dialog('option', 'position', [myDialogX, myDialogY]);
}

I got the same error with something like:

Set rs = dbs.OpenRecordset _
( _
  "SELECT Field1, Field2, FieldN " _
  & "FROM Query1 " _
  & "WHERE Query2.Field1 = """ & Value1 & """;" _
, dbOpenSnapshot _
)

I fixed the error by replacing "Query1" with "Query2"

I would recommend a wrapper that will handle value being changed. For example you can have JavaScript function, like this:

?function Variable(initVal, onChange)
{
    this.val = initVal;          //Value to be stored in this object
    this.onChange = onChange;    //OnChange handler

    //This method returns stored value
    this.GetValue = function()  
    {
        return this.val;
    }

    //This method changes the value and calls the given handler       
    this.SetValue = function(value)
    {
        this.val = value;
        this.onChange();
    }


}

And then you can make an object out of it that will hold value that you want to monitor, and also a function that will be called when the value gets changed. For example, if you want to be alerted when the value changes, and initial value is 10, you would write code like this:

var myVar = new Variable(10, function(){alert("Value changed!");});

Handler function(){alert("Value changed!");} will be called (if you look at the code) when SetValue() is called.

You can get value like so:

alert(myVar.GetValue());

You can set value like so:

myVar.SetValue(12);

And immediately after, an alert will be shown on the screen. See how it works: http://jsfiddle.net/cDJsB/

You can override bean definitions with mocks with spring-reinject https://github.com/sgri/spring-reinject/

Additionally:

• Ctrl-y Moves screen up one line
• Ctrl-e Moves screen down one line
• Ctrl-u Moves cursor & screen up ½ page
• Ctrl-d Moves cursor & screen down ½ page
• Ctrl-b Moves screen up one page, cursor to last line
• Ctrl-f Moves screen down one page, cursor to first line

Ctrl-y and Ctrl-e only change the cursor position if it would be moved off screen.

You could also disable the cascade delete convention in global scope of your application by doing this:

modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>()
modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>()

Explaining if any one want to send some parameters while calling stored procedure as below,

using (SqlConnection con = new SqlConnection(connetionString))
            {
                using (var command = new SqlCommand(storedProcName, con))
                {
                    foreach (var item in sqlParams)
                    {
                        item.Direction = ParameterDirection.Input;
                        item.DbType = DbType.String;
                        command.Parameters.Add(item);
                    }
                    command.CommandType = CommandType.StoredProcedure;
                    using (var adapter = new SqlDataAdapter(command))
                    {
                        adapter.Fill(dt);
                    }
                }
            }

Are you sure you want to do this? In essence, you're duplicating the data that is in the three original columns. From that point on, you'll need to make sure that the data in the combined field matches the data in the first three columns. This is more overhead for your application, and other processes that update the system will need to understand the relationship.

If you need the data, why not select in when you need it? The SQL for selecting what would be in that field would be:

SELECT CONCAT(zipcode, ' - ', city, ', ', state) FROM Table;

This way, if the data in the fields changes, you don't have to update your combined field.

I would do it the following way:

>>> x = np.array([[1,0,0], [0,2,0], [1,1,0]])
>>> x
array([[1, 0, 0],
       [0, 2, 0],
       [1, 1, 0]])
>>> np.nonzero(x)
(array([0, 1, 2, 2]), array([0, 1, 0, 1]))

# if you want it in coordinates
>>> x[np.nonzero(x)]
array([1, 2, 1, 1])
>>> np.transpose(np.nonzero(x))
array([[0, 0],
       [1, 1],
       [2, 0],
       [2, 1])

If its only the cluttering what gives the problem in the constructor why not implement a initialize method that intializes the variables. This is a normal thing to do when the constructor gets to full with unnecessary stuff. Even in typed program languages like C# its normal convention to add an Initialize method to handle that.

You either need to create an object of type Beta in the Alpha class or its method

Like you do here in the Main Beta cBeta = new Beta();

If you want to use the variable you create in your Main then you have to parse it to cAlpha as a parameter by making the Alpha constructor look like

public class Alpha 
{

    Beta localInstance;

    public Alpha(Beta _beta)
    {
        localInstance = _beta;
    }


     public void DoSomethingAlpha() 
     {
          localInstance.DoSomethingAlpha();     
     }
}

I would use Different IDs but assign each DIV the same class.

<div id="c-1" class="countdown"></div>
<div id="c-2" class="countdown"></div>

This also has the added benefit of being able to reconstruct the IDs based off of the return of jQuery('.countdown').length

Ok what about adding multiple classes to each countdown timer. IE:

<div class="countdown c-1"></div>
<div class="countdown c-2"></div>
<div class="countdown c-1"></div>

That way you get the best of both worlds. It even allows repeat 'IDS'

You could try:

var path = @"/Users/smcho/filegen_from_directory/AIRPassthrough/";
var dirName = new DirectoryInfo(path).Name;

There are several possibilities (note that the those long values aren't the same as the Unix epoch.

For your example (to reverse ToFileTime()) just use DateTime.FromFileTime(t).

This is probably the best way, since it’s reliable and works on old browsers:

function indexOfMax(arr) {
    if (arr.length === 0) {
        return -1;
    }

    var max = arr[0];
    var maxIndex = 0;

    for (var i = 1; i < arr.length; i++) {
        if (arr[i] > max) {
            maxIndex = i;
            max = arr[i];
        }
    }

    return maxIndex;
}

There’s also this one-liner:

let i = arr.indexOf(Math.max(...arr));

It performs twice as many comparisons as necessary and will throw a RangeError on large arrays, though. I’d stick to the function.

An exe is an executible program whereas A DLL is a file that can be loaded and executed by programs dynamically.

In the first place, if you are working with other people on the same code repository, you should not delete a commit since when you force the update on the repository it will leave the local repositories of your coworkers in an illegal state (e.g. if they made commits after the one you deleted, those commits will be invalid since they were based on a now non-existent commit).

Said that, what you can do is revert the commit. This procedure is done differently (different commands) depending on the CVS you're using:

On git:

git revert <commit>

On mercurial:

hg backout <REV>

EDIT: The revert operation creates a new commit that does the opposite than the reverted commit (e.g. if the original commit added a line, the revert commit deletes that line), effectively removing the changes of the undesired commit without rewriting the repository history.

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).

This does almost everything you want:

f = open('data.txt', 'rb')

while True:
    char = f.read(1)
    if not char: break
    print "{:02x}".format(ord(char)),

With data.txt created like this:

f = open('data.txt', 'wb')
f.write("ab\r\ncd")
f.close()

I get the following output:

61 62 0d 0a 63 64

tl;dr -- 1. You are using poor variable names. 2. You are slicing your hex strings incorrectly. 3. Your code is never going to replace any newlines. You may just want to forget about that feature. You do not quite yet understand the difference between a character, its integer code, and the hex string that represents the integer. They are all different: two are strings and one is an integer, and none of them are equal to each other. 4. For some files, you shouldn't remove newlines.

===

1. Your variable names are horrendous.

That's fine if you never want to ask anybody questions. But since every one needs to ask questions, you need to use descriptive variable names that anyone can understand. Your variable names are only slightly better than these:

fname = 'data.txt'
f = open(fname, 'rb')
xxxyxx = f.read()

xxyxxx = len(xxxyxx)
print "Length of file is", xxyxxx, "bytes. "
yxxxxx = 0

while yxxxxx < xxyxxx:
    xyxxxx = hex(ord(xxxyxx[yxxxxx]))
    xyxxxx = xyxxxx[-2:]
    yxxxxx = yxxxxx + 1
    xxxxxy = chr(13) + chr(10)
    xxxxyx = str(xxxxxy)
    xyxxxxx = str(xyxxxx)
    xyxxxxx.replace(xxxxyx, ' ')
    print xyxxxxx

That program runs fine, but it is impossible to understand.

2. The hex() function produces strings of different lengths.

For instance,

print hex(61)
print hex(15)

--output:--
0x3d
0xf

And taking the slice [-2:] for each of those strings gives you:

3d
xf

See how you got the 'x' in the second one? The slice:

[-2:] 

says to go to the end of the string and back up two characters, then grab the rest of the string. Instead of doing that, take the slice starting 3 characters in from the beginning:

[2:]  

3. Your code will never replace any newlines.

Suppose your file has these two consecutive characters:

"\r\n"

Now you read in the first character, "\r", and convert it to an integer, ord("\r"), giving you the integer 13. Now you convert that to a string, hex(13), which gives you the string "0xd", and you slice off the first two characters giving you:

"d"

Next, this line in your code:

bndtx.replace(entx, ' ')

tries to find every occurrence of the string "\r\n" in the string "d" and replace it. There is never going to be any replacement because the replacement string is two characters long and the string "d" is one character long.

The replacement won't work for "\r\n" and "0d" either. But at least now there is a possibility it could work because both strings have two characters. Let's reduce both strings to a common denominator: ascii codes. The ascii code for "\r" is 13, and the ascii code for "\n" is 10. Now what about the string "0d"? The ascii code for the character "0" is 48, and the ascii code for the character "d" is 100. Those strings do not have a single character in common. Even this doesn't work:

 x = '0d' + '0a'
 x.replace("\r\n", " ")
 print x

 --output:--
 '0d0a'

Nor will this:

x = 'd' + 'a'
x.replace("\r\n", " ")
print x

--output:--
da

The bottom line is: converting a character to an integer then to a hex string does not end up giving you the original character--they are just different strings. So if you do this:

char = "a"
code = ord(char)
hex_str = hex(code)

print char.replace(hex_str, " ")

...you can't expect "a" to be replaced by a space. If you examine the output here:

char = "a"
print repr(char)

code = ord(char)
print repr(code)

hex_str = hex(code)
print repr(hex_str)

print repr(
    char.replace(hex_str, " ")
)

--output:--
'a'
97
'0x61'
'a'

You can see that 'a' is a string with one character in it, and '0x61' is a string with 4 characters in it: '0', 'x', '6', and '1', and you can never find a four character string inside a one character string.

4) Removing newlines can corrupt the data.

For some files, you do not want to replace newlines. For instance, if you were reading in a .jpg file, which is a file that contains a bunch of integers representing colors in an image, and some colors in the image happened to be represented by the number 13 followed by the number 10, your code would eliminate those colors from the output.

However, if you are writing a program to read only text files, then replacing newlines is fine. But then, different operating systems use different newlines. You are trying to replace Windows newlines(\r\n), which means your program won't work on files created by a Mac or Linux computer, which use \n for newlines. There are easy ways to solve that, but maybe you don't want to worry about that just yet.

I hope all that's not too confusing.

If you are using the static serve view in development, you have to have DEBUG = True :

Warning

This will only work if DEBUG is True.

That's because this view is grossly inefficient and probably insecure. This is only intended for local development, and should never be used in production.

Docs: serving static files in developent

EDIT: You could add some urls just to test your 404 and 500 templates, just use the generic view direct_to_template in your urls.

from django.views.generic.simple import direct_to_template

urlpatterns = patterns('',
    ('^404testing/$', direct_to_template, {'template': '404.html'})
)

I know I am 3 years late on this thread, however still providing my 2 cents for similar cases in future.

I recently faced the same issue/error in my cluster. The JOB would always get to some 80%+ reduction and fail with the same error, with nothing to go on in the execution logs either. Upon multiple iterations and research I found that among the plethora of files getting loaded some were non-compliant with the structure provided for the base table(table being used to insert data into partitioned table).

Point to be noted here is whenever I executed a select query for a particular value in the partitioning column or created a static partition it worked fine as in that case error records were being skipped.

TL;DR: Check the incoming data/files for inconsistency in the structuring as HIVE follows Schema-On-Read philosophy.

See the below example

CREATE TABLE users (
    -- make the "id" column a primary key; this also creates
    -- a UNIQUE constraint and a b+-tree index on the column
    id    SERIAL PRIMARY KEY,
    name  TEXT,
    age   INT4
);

INSERT INTO users (name, age) VALUES ('Mozart', 20);

Then for getting last inserted id use this for table "user" seq column name "id"

SELECT currval(pg_get_serial_sequence('users', 'id'));

List<string> myCollection = new List<string>()
{
    "Bob", "Bob","Alex", "Abdi", "Abdi", "Bob", "Alex", "Bob","Abdi"
};

myCollection.Sort();
foreach (var name in myCollection.Distinct())
{
    Console.WriteLine(name + " " + myCollection.Count(x=> x == name));
}

output: Abdi 3 Alex 2 Bob 4

    alert("both passwords are not matching");
    return false;
  }
  return true;
}

Figured out a simple and nice way:

>>> df
     A  B  C
one  1  2  3
>>> df.loc["two"] = [4,5,6]
>>> df
     A  B  C
one  1  2  3
two  4  5  6

Note the caveat with performance as noted in the comments

Fatal error: Call to undefined function XXX

Happens when you try to call a function that is not defined yet. Common causes include missing extensions and includes, conditional function declaration, function in a function declaration or simple typos.

Example 1 - Conditional Function Declaration

$someCondition = false;
if ($someCondition === true) {
    function fn() {
        return 1;
    }
}
echo fn(); // triggers error

In this case, fn() will never be declared because $someCondition is not true.

Example 2 - Function in Function Declaration

function createFn() 
{
    function fn() {
        return 1;
    }
}
echo fn(); // triggers error

In this case, fn will only be declared once createFn() gets called. Note that subsequent calls to createFn() will trigger an error about Redeclaration of an Existing function.

You may also see this for a PHP built-in function. Try searching for the function in the official manual, and check what "extension" (PHP module) it belongs to, and what versions of PHP support it.

In case of a missing extension, install that extension and enable it in php.ini. Refer to the Installation Instructions in the PHP Manual for the extension your function appears in. You may also be able to enable or install the extension using your package manager (e.g. apt in Debian or Ubuntu, yum in Red Hat or CentOS), or a control panel in a shared hosting environment.

If the function was introduced in a newer version of PHP from what you are using, you may find links to alternative implementations in the manual or its comment section. If it has been removed from PHP, look for information about why, as it may no longer be necessary.

In case of missing includes, make sure to include the file declaring the function before calling the function.

In case of typos, fix the typo.

I had an issue with node.exe programs like test output with mocha.

In my case, I solved it by removing some default "node.exe" alias.

I'm using Git Bash for Windows(2.29.2) and some default aliases are set from /etc/profile.d/aliases.sh,

  # show me alias related to 'node'
  $ alias|grep node
  alias node='winpty node.exe'`

To remove the alias, update aliases.sh or simply do

unalias node

I don't know why winpty has this side effect on console.info buffered output but with a direct node.exe use, I've no more stdout issue.

Given how mangled some data can look after BCP importing into SQL Server from non-SQL data sources, I'd suggest doing all the BCP import into some scratch tables first.

For example

truncate table Address_Import_tbl

BULK INSERT dbo.Address_Import_tbl FROM 'E:\external\SomeDataSource\Address.csv' WITH ( FIELDTERMINATOR = '|', ROWTERMINATOR = '\n', MAXERRORS = 10 )

Make sure all the columns in Address_Import_tbl are nvarchar(), to make it as agnostic as possible, and avoid type conversion errors.

Then apply whatever fixes you need to Address_Import_tbl. Like deleting the unwanted header.

Then run a INSERT SELECT query, to copy from Address_Import_tbl to Address_tbl, along with any datatype conversions you need. For example, to cast imported dates to SQL DATETIME.

Steps I used to resolve it:

1. Double click on Tomcat Server in the Servers tab.
2. In a dropdown next to Runtime Environment:, select Apache Tomcat your version
3. Click on save.

Now, you should be able to add to server on right click "Add and Remove".

Note: Additionally, when on clear/run, you get an error for multiple instances, open server.xml and ensure that it contains a single instance of each application and not multiple.

Evidently you can use Arrays.fill(), The way you have it done also works though.

This limitation affected me when I tried to overload operators for generic types; since there was no "INumeric" constraint, and for a bevy of other reasons the good people on stackoverflow are happy to provide, operations cannot be defined on generic types.

I wanted something like

public struct Foo<T>
{
    public T Value{ get; private set; }

    public static Foo<T> operator +(Foo<T> LHS, Foo<T> RHS)
    {
        return new Foo<T> { Value = LHS.Value + RHS.Value; };
    }
}

I have worked around this issue using .net4 dynamic runtime typing.

public struct Foo<T>
{
    public T Value { get; private set; }

    public static Foo<T> operator +(Foo<T> LHS, Foo<T> RHS)
    {
        return new Foo<T> { Value = LHS.Value + (dynamic)RHS.Value };
    }
}

The two things about using dynamic are

1. Performance. All value types get boxed.
2. Runtime errors. You "beat" the compiler, but lose type safety. If the generic type doesn't have the operator defined, an exception will be thrown during execution.

In C# and VB the SqlCommand object implements the Parameter.AddWithValue method which handles this situation

public static string XmlEscape(string unescaped)
{
    XmlDocument doc = new XmlDocument();
    XmlNode node = doc.CreateElement("root");
    node.InnerText = unescaped;
    return node.InnerXml;
}

public static string XmlUnescape(string escaped)
{
    XmlDocument doc = new XmlDocument();
    XmlNode node = doc.CreateElement("root");
    node.InnerXml = escaped;
    return node.InnerText;
}

Thread.currentThread().getStackTrace();

is available since JDK1.5.

For an older version, you can redirect exception.printStackTrace() to a StringWriter() :

StringWriter sw = new StringWriter();
new Throwable("").printStackTrace(new PrintWriter(sw));
String stackTrace = sw.toString();

You can use the bind function to set the context of this within a function.

function myFunc() {
  console.log(this.str)
}
const myContext = {str: "my context"}
const boundFunc = myFunc.bind(myContext);
boundFunc(); // "my context"

This can be a solution .

[Test]
public void TestForOutParameterInMoq()
{
  //Arrange
  _mockParameterManager= new Mock<IParameterManager>();

  Mock<IParameter > mockParameter= new Mock<IParameter >();
  //Parameter affectation should be useless but is not. It's really used by Moq 
  IParameter parameter= mockParameter.Object;

  //Mock method used in UpperParameterManager
  _mockParameterManager.Setup(x => x.OutMethod(out parameter));

  //Act with the real instance
  _UpperParameterManager.UpperOutMethod(out parameter);

  //Assert that method used on the out parameter of inner out method are really called
  mockParameter.Verify(x => x.FunctionCalledInOutMethodAfterInnerOutMethod(),Times.Once());

}

You can use the LIKE operator to compare the content of a T-SQL string, e.g.

SELECT * FROM [table] WHERE [field] LIKE '%stringtosearchfor%'.

The percent character '%' is a wild card- in this case it says return any records where [field] at least contains the value "stringtosearchfor".

Another way is to use the subplots function and pass the width ratio with gridspec_kw:

import numpy as np
import matplotlib.pyplot as plt 

# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)

f.tight_layout()
f.savefig('grid_figure.pdf')

This comes up a lot when your gemfile.lock has different versions of the gems installed on your machine. You may get a warning after running rake (or rspec or others) such as:

You have already activated rake 10.3.1, but your Gemfile requires rake 10.1.0. Prepending "bundle exec" to your command may solve this.

Prepending bundle exec tells the bundler to execute this command regardless of the version differential. There isn't always an issue, however, you might run into problems.

Fortunately, there is a gem that solves this: rubygems-bundler.

$ gem install rubygems-bundler

$ $ gem regenerate_binstubs

Then try your rake, rspec, or whatever again.

If you use php-fpm, the php_admin_value will NOT work and gives an Internal Server Error.

Instead use this in your .htaccess. It disables the parser in that folder and all subfolders:

<FilesMatch ".+\.*$">
    SetHandler !
</FilesMatch>

According to my interpretation of the implementation of unicode-escape and the unicode repr in the CPython 2.6.5 source, yes; the only difference between repr(unicode_string) and unicode_string.encode('unicode-escape') is the inclusion of wrapping quotes and escaping whichever quote was used.

They are both driven by the same function, unicodeescape_string. This function takes a parameter whose sole function is to toggle the addition of the wrapping quotes and escaping of that quote.

Sorry for answering so late.

I figured an answer alike to @xlm 's:

task run (type: JavaExec, dependsOn: classes){
    if(project.hasProperty('myargs')){
        args(myargs.split(','))
    }
    description = "Secure algorythm testing"
    main = "main.Test"
    classpath = sourceSets.main.runtimeClasspath
}

And invoke like:

gradle run -Pmyargs=-d,s

You can learn something called "mocking". You can use this, for example, to check if: - a function was called - a function was called x times - a function was called at least x times - a function was called with a specific set of parameters. In your case, for example, you can use mocking to check that method3 was called once with whatever you pass as arg1 and arg2.

Have a look at these: https://code.google.com/p/mockito/ https://code.google.com/p/powermock/

For Linux Run this command

date -d '06/12/2012 07:21:22' +"%s"

For mac OSX run this command

Just for information sake, in regards to my need... The answer I was looking for here was:

Mage::app()->getStore()->getGroup()->getName()

That is referenced on the admin page, where one can manage multiple stores... admin/system_store, I wanted to retrieve the store group title...

You can use the following CSS to style the input element.

input[type="date"] {_x000D_
  background-color: red;_x000D_
  outline: none;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-clear-button {_x000D_
  font-size: 18px;_x000D_
  height: 30px;_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-inner-spin-button {_x000D_
  height: 28px;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-calendar-picker-indicator {_x000D_
  font-size: 15px;_x000D_
}

<input type="date" value="From" name="from" placeholder="From" required="" />

Never try to edit to @_ variable!!!! They must be not touched.. Or you get some unsuspected effect. For example...

my $size=1234;
sub sub1{
  $_[0]=500;
}
sub1 $size;

Before call sub1 $size contain 1234. But after 500(!!) So you Don't edit this value!!! You may pass two or more values and change them in subroutine and all of them will be changed! I've never seen this effect described. Programs I've seen also leave @_ array readonly. And only that you may safely pass variable don't changed internal subroutine You must always do that:

sub sub2{
  my @m=@_;
  ....
}

assign @_ to local subroutine procedure variables and next worked with them. Also in some deep recursive algorithms that returun array you may use this approach to reduce memory used for local vars. Only if return @_ array the same.

There are two ways to handle CGI scripts, SetHandler and AddHandler.

SetHandler cgi-script

applies to all files in a given context, no matter how they are named, even index.html or style.css.

AddHandler cgi-script .pl

is similar, but applies to files ending in .pl, in a given context. You may choose another extension or several, if you like.

Additionally, the CGI module must be loaded and Options +ExecCGI configured. To activate the module, issue

a2enmod cgi

and restart or reload Apache. Finally, the Perl CGI script must be executable. So the execute bits must be set

chmod a+x script.pl

and it should start with

#! /usr/bin/perl

as its first line.

When you use SetHandler or AddHandler (and Options +ExecCGI) outside of any directive, it is applied globally to all files. But you may restrict the context to a subset by enclosing these directives inside, e.g. Directory

<Directory /path/to/some/cgi-dir>
    SetHandler cgi-script
    Options +ExecCGI
</Directory>

Now SetHandler applies only to the files inside /path/to/some/cgi-dir instead of all files of the web site. Same is with AddHandler inside a Directory or Location directive, of course. It then applies to the files inside /path/to/some/cgi-dir, ending in .pl.

The Gutenberg Project hosts Webster's Unabridged English Dictionary plus many other public domain literary works. Actually it looks like they've got several versions of the dictionary hosted with copyright from different years. The one I linked has a 2009 copyright. You may want to poke around the site and investigate the different versions of Webster's dictionary.

public class TestRound11 {
  public static void main(String args[]){
    double d = 3.1537;
    BigDecimal bd = new BigDecimal(d);
    bd = bd.setScale(2,BigDecimal.ROUND_HALF_UP);
    // output is 3.15
    System.out.println(d + " : " + round(d, 2));

? Splitting line in Python:

Have you tried using str.splitlines() method?:

• Python 2.X documentation here.
• Python 3.X documentation here.

From the docs:

str.splitlines([keepends])

Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.

For example:

>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()
['Line 1', '', 'Line 3', 'Line 4']

>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines(True)
['Line 1\n', '\n', 'Line 3\r', 'Line 4\r\n']

Which delimiters are considered?

This method uses the universal newlines approach to splitting lines.

The main difference between Python 2.X and Python 3.X is that the former uses the universal newlines approach to splitting lines, so "\r", "\n", and "\r\n" are considered line boundaries for 8-bit strings, while the latter uses a superset of it that also includes:

• \v or \x0b: Line Tabulation (added in Python 3.2).
• \f or \x0c: Form Feed (added in Python 3.2).
• \x1c: File Separator.
• \x1d: Group Separator.
• \x1e: Record Separator.
• \x85: Next Line (C1 Control Code).
• \u2028: Line Separator.
• \u2029: Paragraph Separator.

splitlines VS split:

Unlike str.split() when a delimiter string sep is given, this method returns an empty list for the empty string, and a terminal line break does not result in an extra line:

>>> ''.splitlines()
[]

>>> 'Line 1\n'.splitlines()
['Line 1']

While str.split('\n') returns:

>>> ''.split('\n')
['']

>>> 'Line 1\n'.split('\n')
['Line 1', '']

?? Removing additional whitespace:

If you also need to remove additional leading or trailing whitespace, like spaces, that are ignored by str.splitlines(), you could use str.splitlines() together with str.strip():

>>> [str.strip() for str in 'Line 1  \n  \nLine 3 \rLine 4 \r\n'.splitlines()]
['Line 1', '', 'Line 3', 'Line 4']

? Removing empty strings (''):

Lastly, if you want to filter out the empty strings from the resulting list, you could use filter():

>>> # Python 2.X:
>>> filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines())
['Line 1', 'Line 3', 'Line 4']

>>> # Python 3.X:
>>> list(filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()))
['Line 1', 'Line 3', 'Line 4']

Additional comment regarding the original question:

As the error you posted indicates and Burhan suggested, the problem is from the print. There's a related question about that could be useful to you: UnicodeEncodeError: 'charmap' codec can't encode - character maps to <undefined>, print function

As others have explained, var self = this; allows code in a closure to refer back to the parent scope.

However, it's now 2018 and ES6 is widely supported by all major web browsers. The var self = this; idiom isn't quite as essential as it once was.

It's now possible to avoid var self = this; through the use of arrow functions.

In instances where we would have used var self = this:

function test() {
    var self = this;
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", function() {
        console.log(self.hello); // logs "world"
    });
};

We can now use an arrow function without var self = this:

function test() {
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", () => {
        console.log(this.hello); // logs "world"
    });
};

Arrow functions do not have their own this and simply assume the enclosing scope.

var map_marker = $(".map-marker").children("img").attr("src") var pinImage = new google.maps.MarkerImage(map_marker);

     var marker = new google.maps.Marker({
      position: uluru,
      map: map,
      icon: pinImage
    });
  }

I would advise you to use pylibmc instead.

It can act as a drop-in replacement of python-memcache, but a lot faster(as it's written in C). And you can find handy documentation for it here.

And to the question, as pylibmc just acts as a drop-in replacement, you can still refer to documentations of pylibmc for your python-memcache programming.

I faced similar problem. So far I know result may different for different names, so finally came to this solution.

public String getMimeType(String filePath) {
    String type = null;
    String extension = null;
    int i = filePath.lastIndexOf('.');
    if (i > 0)
        extension = filePath.substring(i+1);
    if (extension != null)
        type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
    return type;
}  

IMHO the best option is to use YAML's native block scalars. Specifically in this case, the folded style block.

By invoking sh -c you can pass arguments to your container as commands, but if you want to elegantly separate them with newlines, you'd want to use the folded style block, so that YAML will know to convert newlines to whitespaces, effectively concatenating the commands.

A full working example:

apiVersion: v1
kind: Pod
metadata:
  name: myapp
  labels:
    app: myapp
spec:
  containers:
  - name: busy
    image: busybox:1.28
    command: ["/bin/sh", "-c"]
    args:
    - >
      command_1 &&
      command_2 &&
      ... 
      command_n

Explain why the following code displays 2.5 instead of 3:

$a = 012;
echo $a / 4;

Answer: When a number is preceded by a 0 in PHP, the number is treated as an octal number (base-8). Therefore the octal number 012 is equal to the decimal number 10.

I think that the best choice for you is using SwipeRefreshLayout View in your layout. Then set RefreshListener like.

mySwipeRefreshLayout.setOnRefreshListener(
            new SwipeRefreshLayout.OnRefreshListener() {
                @Override
                public void onRefresh() {
                    Log.i("Fav ", "onRefresh called from SwipeRefreshLayout");

                    // This method performs the actual data-refresh operation.
                    // The method calls setRefreshing(false) when it's finished.
                    request();  // call what you want to update in this method
                    mySwipeRefreshLayout.setRefreshing(false);
                }
            }
    );

Got it !

Wanted to force the date shown = server date, no mattter the local settings (UTC).

My server is GMT-6 --> new Date().getTimezoneOffset() = 360.

myTZO = 360;
myNewDate=new Date(myOldDateObj.getTime() + (60000*(myOldDateObj.getTimezoneOffset()-myTZO)));
alert(myNewDate);

Take a try on the tiny free tool:

http://keyangxiang.com/csvtojson/

It utilises node.js csvtojson module

If you're running this on a cluster then println won't print back to your context. You need to bring the RDD data to your session. To do this you can force it to local array and then print it out:

linesWithSessionId.toArray().foreach(line => println(line))

In my situation, the IIS Express applicationhost.config file had a typo in the managedRuntimeVersion attribute of several elements. This was happening for both Visual Studio 2012 and Visual Studio 2013. I only received the first part of the message, stating:

Unable to launch the IIS Express Web server.

It logged an error in the event log with the message:

The worker process failed to pre-load .Net Runtime version v4.030319.

The correct runtime version is v4.0.30319 (note the second period.)

The steps I took to correct:

1. Navigate to C:\Users\\Documents\IISExpress\config
2. Edit applicationhost.config
3. Find the config section
4. Correct any references to "v4.030319" to read "v4.0.30319"

Visual Studio successfully started IIS Express the next time I debugged a web application.

TASKLIST doesn't set an exit code that you could check in a batch file. One workaround to checking the exit code could be parsing its standard output (which you are presently redirecting to NUL). Apparently, if the process is found, TASKLIST will display its details, which include the image name too. Therefore, you could just use FIND or FINDSTR to check if the TASKLIST's output contains the name you have specified in the request. Both FIND and FINDSTR set a non-null exit code if the search was unsuccessful. So, this would work:

@echo off
tasklist /fi "imagename eq notepad.exe" | find /i "notepad.exe" > nul
if not errorlevel 1 (taskkill /f /im "notepad.exe") else (
  specific commands to perform if the process was not found
)
exit

There's also an alternative that doesn't involve TASKLIST at all. Unlike TASKLIST, TASKKILL does set an exit code. In particular, if it couldn't terminate a process because it simply didn't exist, it would set the exit code of 128. You could check for that code to perform your specific actions that you might need to perform in case the specified process didn't exist:

@echo off
taskkill /f /im "notepad.exe" > nul
if errorlevel 128 (
  specific commands to perform if the process
  was not terminated because it was not found
)
exit

It's always advised to never destructively destroy an existing classpath unless you have a good reason.

The following line preserves the existing classpath and adds onto it.

export CLASSPATH="$CLASSPATH:foo.jar:../bar.jar"

Third or nth maximum salary from salary table without using subquery

select salary from salary
   ORDER   BY salary DESC
   OFFSET  N-1 ROWS
   FETCH NEXT 1 ROWS ONLY

For 3rd highest salary put 2 in place of N-1

Updated answer (Jan 2020)

xargs is now the recommended tool to achieve parallel execution. It's pre-installed almost everywhere. For running multiple rsync tasks the command would be:

ls /srv/mail | xargs -n1 -P4 -I% rsync -Pa % myserver.com:/srv/mail/

This will list all folders in /srv/mail, pipe them to xargs, which will read them one-by-one and and run 4 rsync processes at a time. The % char replaces the input argument for each command call.

Original answer using parallel:

ls /srv/mail | parallel -v -j8 rsync -raz --progress {} myserver.com:/srv/mail/{}

I like this one.

wmic process where "name like '%java%'" delete

You can actually kill a process on a remote machine the same way.

wmic /node:computername /user:adminuser /password:password process where "name like '%java%'" delete

wmic is awesome!

Let's say you have defined an empty array:

$myArr = array();

If you want to simply add an element, e.g. 'New Element to Array', write

$myArr[] = 'New Element to Array';

if you are calling the data from the database, below code will work fine

$sql = "SELECT $element FROM $table";
$query = mysql_query($sql);
if(mysql_num_rows($query) > 0)//if it finds any row
{
   while($result = mysql_fetch_object($query))
   {
      //adding data to the array
      $myArr[] = $result->$element;
   }
}

you have to update your node.js and angular/cli.If you update these two things then your project has angular.json file instead of angular-cli.json file.Then add css file into angular.json file.If you add css file into angular-cli.json file instead of angular.json file,then errors are occured.

Don't.

Because:

• Clbuttic
• Profanity is not OMG EVIL
• Profanity cannot be effectively defined
• Most people quite probably don't appreciate being "protected" from profanity

Edit: While I agree with the commenter who said "censorship is wrong", that is not the nature of this answer.

I'm writing a new answer which hopefully helps anyone looking for similar to what I am.

This works in the case of "I have multiple needles and I'm trying to use them to find a singled-out string". and this is the question I came across to find that.

    $i = 0;
    $found = array();
    while ($i < count($needle)) {
        $x = 0;
        while ($x < count($haystack)) {
            if (strpos($haystack[$x], $needle[$i]) !== false) {
                array_push($found, $haystack[$x]);
            }
            $x++;
        }
        $i++;
    }

    $found = array_count_values($found);

The array $found will contain a list of all the matching needles, the item of the array with the highest count value will be the string(s) you're looking for, you can get this with:

print_r(array_search(max($found), $found));

Just to make this absolutely clear for all:

A .MDF file is “typically” a SQL Server data file however it is important to note that it does NOT have to be.

This is because .MDF is nothing more than a recommended/preferred notation but the extension itself does not actually dictate the file type.

To illustrate this, if someone wanted to create their primary data file with an extension of .gbn they could go ahead and do so without issue.

To qualify the preferred naming conventions:

• .mdf - Primary database data file.
• .ndf - Other database data files i.e. non Primary.
• .ldf - Log data file.

Use

var arrayNames = (from DataColumn x in dt.Columns
                  select x.ColumnName).ToArray();

Just got this, we can achieve it using onpaste:"return false", thanks to: http://sumtips.com/2011/11/prevent-copy-cut-paste-text-field.html

We have various other options available as listed below.

<input type="text" onselectstart="return false" onpaste="return false;" onCopy="return false" onCut="return false" onDrag="return false" onDrop="return false" autocomplete=off/><br>

Apparently the solution differs between Ubuntu versions. Following worked for me on Ubuntu 13.10:

sudo apt-get install nodejs-legacy

HTH

Edit: Rule of thumb:

If you have installed nodejs but are missing the /usr/bin/node binary, then also install nodejs-legacy. This just creates the missing softlink.

According to my tests, Ubuntu 17.10 and above already have the compatibility-softlink /usr/bin/node in place after nodejs is installed, so nodejs-legacy is missing from these releases as it is no more needed.

One liner just set devMode true/false;

console.log = devMode ? console.log : () => { };

I use this:

@var.respond_to?(:keys)

It works for Hash and ActiveSupport::HashWithIndifferentAccess.

You can find creation time - aka birth time - using stat and also match using find.
We have these files showing last modified time:

$ ls -l --time-style=long-iso | sort -k6
total 692
-rwxrwx---+ 1 XXXX XXXX 249159 2013-05-31 14:47 Getting Started.pdf
-rwxrwx---+ 1 XXXX XXXX 275799 2013-12-30 21:12 TheScienceofGettingRich.pdf
-rwxrwx---+ 1 XXXX XXXX  25600 2015-05-07 18:52 Thumbs.db
-rwxrwx---+ 1 XXXX XXXX 148051 2015-05-07 18:55 AsAManThinketh.pdf

To find files created within a certain time frame using find as below.
Clearly, the filesystem knows about the birth time of a file:

$ find -newerBt '2014-06-13' ! -newerBt '2014-06-13 12:16:10' -ls 
20547673299906851  148 -rwxrwx---   1 XXXX XXXX   148051 May  7 18:55 ./AsAManThinketh.pdf
1407374883582246  244 -rwxrwx---   1 XXXX XXXX   249159 May 31  2013 ./Getting\ Started.pdf

We can confirm this using stat:

$ stat -c "%w %n" * | sort
2014-06-13 12:16:03.873778400 +0100 AsAManThinketh.pdf
2014-06-13 12:16:04.006872500 +0100 Getting Started.pdf

2015-05-07 18:32:26.938446200 +0100 Thumbs.db

stat man pages explains %w:

As described here for a post request :

var http = require('http');

var options = {
  host: 'www.host.com',
  path: '/',
  port: '80',
  method: 'POST'
};

callback = function(response) {
  var str = ''
  response.on('data', function (chunk) {
    str += chunk;
  });

  response.on('end', function () {
    console.log(str);
  });
}

var req = http.request(options, callback);
//This is the data we are posting, it needs to be a string or a buffer
req.write("data");
req.end();

With a list comprehension:

a = [x - 13 for x in a]

You will have to override the OnPaint method, call the base implementation and the paint your own text.

You will need to create your own CustomProgressBar and then override OnPaint to draw what ever text you want.

Custom Progress Bar Class

namespace ProgressBarSample
{

public enum ProgressBarDisplayText
{
    Percentage,
    CustomText
}

class CustomProgressBar: ProgressBar
{
    //Property to set to decide whether to print a % or Text
    public ProgressBarDisplayText DisplayStyle { get; set; }

    //Property to hold the custom text
    public String CustomText { get; set; }

    public CustomProgressBar()
    {
        // Modify the ControlStyles flags
        //http://msdn.microsoft.com/en-us/library/system.windows.forms.controlstyles.aspx
        SetStyle(ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true);
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        Rectangle rect = ClientRectangle;
        Graphics g = e.Graphics;

        ProgressBarRenderer.DrawHorizontalBar(g, rect);
        rect.Inflate(-3, -3);
        if (Value > 0)

Type it in one cell, copy that cell, select all the cells you want to fill, and paste.

Alternatively, type it in one cell, select the black square in the bottom-right of that cell, and drag down.

You could search all the option values until it finds the correct one.

var defaultVal = "Country";
$("#select").find("option").each(function () {

    if ($(this).val() == defaultVal) {

        $(this).prop("selected", "selected");
    }
});

I haven't tried it, but you may want to download this version of Portable Python. It comes with Scipy-0.7.0b1 running on Python 2.5.4.

Cellspacing is all around the cell and cannot be changed (i.e. if it's set to one, there will be 1 pixel of space on all sides). Padding can be specified discreetly (e.g. padding-top, padding-bottom, padding-left, and padding-right; or padding: [top] [right] [bottom] [left];).

If you are running multiple extensions that perform ad or script blocking you will need to

individually update each one to your whitelist

Taking from this source, here are some of the extensions that may cause the case and how to deal with them.

JavaScript is case-sensitive. The b in getElementbyId should be capitalized.

var content = document.getElementById("edit").innerHTML;

How about

apply(df, 1, function(r) any(r %in% c("M017", "M018")))

The ith element will be TRUE if the ith row contains one of the values, and FALSE otherwise. Or, if you want just the row numbers, enclose the above statement in which(...).

Due to the disadvantages described below, I would recommend following the accepted answer:

Use npm install --save-dev [package_name] then execute scripts with:

$ npm run lint
$ npm run build
$ npm test

My original but not recommended answer follows.

Instead of using a global install, you could add the package to your devDependencies (--save-dev) and then run the binary from anywhere inside your project:

"$(npm bin)/<executable_name>" <arguments>...

In your case:

"$(npm bin)"/node.io --help

This engineer provided an npm-exec alias as a shortcut. This engineer uses a shellscript called env.sh. But I prefer to use $(npm bin) directly, to avoid any extra file or setup.

Although it makes each call a little larger, it should just work, preventing:

• potential dependency conflicts with global packages (@nalply)
• the need for sudo
• the need to set up an npm prefix (although I recommend using one anyway)

Disadvantages:

• $(npm bin) won't work on Windows.
• Tools deeper in your dev tree will not appear in the npm bin folder. (Install npm-run or npm-which to find them.)

It seems a better solution is to place common tasks (such as building and minifying) in the "scripts" section of your package.json, as Jason demonstrates above.

In C# 8.0 you can get the first five characters of a string like so

string str = data[0..5];

Here is some more information about Indices And Ranges

Faced similar issue, and here is the solution

Example :

1. In elasticsearch.yml add the below properties

   cluster.name: production
   node.name: node1
   network.bind_host: 10.0.1.22
   network.host: 0.0.0.0
   transport.tcp.port: 9300
   

2. Add the following in Java Elastic API for Bulk Push (just a code snippet). For IP Address add public IP address of elastic search machine

   Client client;
   BulkRequestBuilder requestBuilder;
   try {
       client = TransportClient.builder().settings(Settings.builder().put("cluster.name", "production").put("node.name","node1")).build().addTransportAddress(
       new InetSocketTransportAddress(InetAddress.getByName(""), 9300));
       requestBuilder = (client).prepareBulk();
   } 
   catch (Exception e) {
   }
   

3. Open the Firewall ports for 9200,9300

Make sure the variable is on the top part of the block, and in case you compile it with -ansi-pedantic, make sure it looks like this:

function() {
    int i;
    i = 0;

    someCode();
}

Some different and clean way to achieve this is by using HttpClient like this:

public async Task<HttpResponseMessage> PostResult(string url, ResultObject resultObject)
{
    using (var client = new HttpClient())
    {
        HttpResponseMessage response = new HttpResponseMessage();
        try
        {
            response = await client.PostAsJsonAsync(url, resultObject);
        }
        catch (Exception ex)
        {
            throw ex
        }
        return response;
     }
}

int *a[], when used as a function parameter (but not in normal declarations), is a pointer to a pointer, not a pointer to an array (in normal declarations, it is an array of pointers). A pointer to an array looks like this:

int (*aptr)[N]

Where N is a particular positive integer (not a variable).

If you make your function a template, you can do it and you don't even need to pass the size of the array (because it is automatically deduced):

template<size_t SZ>
void generateArray(int (*aptr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        (*aptr)[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(&a);
}

You could also take a reference:

template<size_t SZ>
void generateArray(int (&arr)[SZ])
{
    for (size_t i=0; i<SZ; ++i)
        arr[i] = rand() % 9;
}

int main()
{    
    int a[5];    
    generateArray(a);
}

With Underscore

Underscore provides a function _.mapObject to map the values and preserve the keys.

_.mapObject({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

DEMO

With Lodash

Lodash provides a function _.mapValues to map the values and preserve the keys.

_.mapValues({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

To see the devices I was interested in, I had replace Win32_USBHub by Win32_PnPEntity in Adel Hazzah's code, based on this post. This works for me:

namespace ConsoleApplication1
{
  using System;
  using System.Collections.Generic;
  using System.Management; // need to add System.Management to your project references.

  class Program
  {
    static void Main(string[] args)
    {
      var usbDevices = GetUSBDevices();

      foreach (var usbDevice in usbDevices)
      {
        Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
            usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
      }

      Console.Read();
    }

    static List<USBDeviceInfo> GetUSBDevices()
    {
      List<USBDeviceInfo> devices = new List<USBDeviceInfo>();

      ManagementObjectCollection collection;
      using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_PnPEntity"))
        collection = searcher.Get();      

      foreach (var device in collection)
      {
        devices.Add(new USBDeviceInfo(
        (string)device.GetPropertyValue("DeviceID"),
        (string)device.GetPropertyValue("PNPDeviceID"),
        (string)device.GetPropertyValue("Description")
        ));
      }

      collection.Dispose();
      return devices;
    }
  }

  class USBDeviceInfo
  {
    public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
    {
      this.DeviceID = deviceID;
      this.PnpDeviceID = pnpDeviceID;
      this.Description = description;
    }
    public string DeviceID { get; private set; }
    public string PnpDeviceID { get; private set; }
    public string Description { get; private set; }
  }
}

Data can be pulled into an excel from another excel through Workbook method or External reference or through Data Import facility.

If you want to read or even if you want to update another excel workbook, these methods can be used. We may not depend only on VBA for this.

For more info on these techniques, please click here to refer the article

you should be able to just overwrite it without removing previous data

In debian/ubuntu, you'll need to edit the /etc/init.d/mongodb script. Really, this file should be pulling the settings from /etc/mongodb.conf but it doesn't seem to pull the default directory (probably a bug)

This is a bit of a hack, but adding these to the script made it start correctly:

add:

DBDIR=/database/mongodb

change:

DAEMON_OPTS=${DAEMON_OPTS:-"--unixSocketPrefix=$RUNDIR --config $CONF run"}

to:

DAEMON_OPTS=${DAEMON_OPTS:-"--unixSocketPrefix=$RUNDIR --dbpath $DBDIR --config $CONF run"}

There is no built-in formula in excel, you have to add a vb script and permanently save it with your MS. Excel's installation as Add-In.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

1. Inside the child component add a ref to the node you need
2. Inside the parent component add a ref to the child component.

      <div id="child">
        <h1 ref={(node) => { this.heading = node; }}>

Assuming you don't want to immediately decode it again like others are suggesting here, you can parse it to a string and then just strip the leading 'b and trailing '.

>>> x = "Hi there " 
>>> x = "Hi there ".encode("utf-8") 
>>> x
b"Hi there \xef\xbf\xbd"
>>> str(x)[2:-1]
"Hi there \\xef\\xbf\\xbd"

A better way to write the async function would be by returning a pending Promise from the start and then handling both rejections and resolutions within the callback of the promise, rather than just spitting out a rejected promise on error. Example:

async foo(id: string): Promise<A> {
    return new Promise(function(resolve, reject) {
        // execute some code here
        if (success) { // let's say this is a boolean value from line above
            return resolve(success);
        } else {
            return reject(error); // this can be anything, preferably an Error object to catch the stacktrace from this function
        }
    });
}

Then you just chain methods on the returned promise:

async function bar () {
    try {
        var result = await foo("someID")
        // use the result here
    } catch (error) {
        // handle error here
    }
}

bar()

Found an alternate solution over at DotNetPerls that I liked better because it doesn't require you to specify a path. Here's an example where I populated an array with the help of a custom method

        // This custom method takes a path 
        // and adds all files and folder names to the 'files' array
        string[] files = Utilities.FileList("C:\", "");
        // Then for each array item...
        foreach (string f in files)
        {
            // Here is the important line I used to ommit .DLL files:
            if (!f.EndsWith(".dll", StringComparison.Ordinal))
                // then populated a listBox with the array contents
                myListBox.Items.Add(f);
        }

If you don't have any server side code, you security depends on the security of the access to your JavaScript code on the client side (ie everybody who has the code could upload something).

So I would recommend, to simply create a special S3 bucket which is public writeable (but not readable), so you don't need any signed components on the client side.

The bucket name (a GUID eg) will be your only defense against malicious uploads (but a potential attacker could not use your bucket to transfer data, because it is write only to him)

Compare NET Objects can help you!

CompareLogic logic = new CompareLogic();
var compare = logic.Compare(obj1, obj2);
comparacao.Differences.ForEach(diff => Debug.Write(diff.PropertyName));
// Or formatted summary
Debug.Write(comparacao.DifferencesString);

It can be something as simple as typing the package name in the wrong case...

I had the same problem - turned out I was entering the package name in all lower case when the actual package name included upper case characters.

adb uninstall -k <packageName - eg. com.test.app>

( If you're explicitly uninstalling you probably don't want the -k which keeps the app data and cache directories around. )

My use case was to save multiple JSON objects to a file and marty's answer helped me somewhat. But to serve my use case, the answer was not complete as it would overwrite the old data every time a new entry was saved.

To save multiple entries in a file, one must check for the old content (i.e., read before write). A typical file holding JSON data will either have a list or an object as root. So I considered that my JSON file always has a list of objects and every time I add data to it, I simply load the list first, append my new data in it, and dump it back to a writable-only instance of file (w):

def saveJson(url,sc): # This function writes the two values to the file
    newdata = {'url':url,'sc':sc}
    json_path = "db/file.json"

    old_list= []
    with open(json_path) as myfile:  # Read the contents first
        old_list = json.load(myfile)
    old_list.append(newdata)

    with open(json_path,"w") as myfile:  # Overwrite the whole content
        json.dump(old_list, myfile, sort_keys=True, indent=4)

    return "success"

The new JSON file will look something like this:

[
    {
        "sc": "a11",
        "url": "www.google.com"
    },
    {
        "sc": "a12",
        "url": "www.google.com"
    },
    {
        "sc": "a13",
        "url": "www.google.com"
    }
]

NOTE: It is essential to have a file named file.json with [] as initial data for this approach to work

PS: not related to original question, but this approach could also be further improved by first checking if our entry already exists (based on one or multiple keys) and only then append and save the data.

What you're missing: Zero is a value

You can iterate over "a file", which produces lines, including the trailing newline character. To make a "virtual file" out of a string, you can use StringIO:

import io  # for Py2.7 that would be import cStringIO as io

for line in io.StringIO(foo):
    print(repr(line))

Note: Git 1.8.2 added the possibility to track branches. See some of the answers below.

It's a little confusing to get used to this, but submodules are not on a branch. They are, like you say, just a pointer to a particular commit of the submodule's repository.

This means, when someone else checks out your repository, or pulls your code, and does git submodule update, the submodule is checked out to that particular commit.

This is great for a submodule that does not change often, because then everyone on the project can have the submodule at the same commit.

If you want to move the submodule to a particular tag:

cd submodule_directory
git checkout v1.0
cd ..
git add submodule_directory
git commit -m "moved submodule to v1.0"
git push

Then, another developer who wants to have submodule_directory changed to that tag, does this

git pull
git submodule update --init

git pull changes which commit their submodule directory points to. git submodule update actually merges in the new code.

In case we want to dump the in memory file to disk. This code can be used

  if isinstanceof(obj,SpooledTemporaryFile):
    obj.rollover()

For this you can use CSS3 background-size property. Write like this:

#div2{
    background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
    -moz-background-size:100% 100%;
    -webkit-background-size:100% 100%;
    background-size:100% 100%;
    height:180px;
    width:200px;
    border: 1px solid red;
}

Check this: http://jsfiddle.net/qdzaw/1/

You can just try

$(document).ready(function() {
   $('body').find('#item').removeClass();
});

If you have to access to that element without class name, for example you have to add a new class name, you can do that:

$(document).ready(function() {
   $('body').find('#item').removeClass().addClass('class-name');
});

I use that function in my projet to remove and add class in a html builder. Good luck.

you can use character classes

/[[:cntrl:]]+/

try this code :

private GoogleMap mMap;


LocationManager locationManager;


private static final String TAG = "";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(map);
    mapFragment.getMapAsync(this);

    arrayPoints = new ArrayList<LatLng>();
}

@Override
public void onMapReady(GoogleMap googleMap) {


    mMap = googleMap;


    mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);


    LatLng myPosition;


    if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

        // to handle the case where the user grants the permission. See the documentation
        // for ActivityCompat#requestPermissions for more details.
        return;
    }
    googleMap.setMyLocationEnabled(true);
    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    Criteria criteria = new Criteria();
    String provider = locationManager.getBestProvider(criteria, true);
    Location location = locationManager.getLastKnownLocation(provider);


    if (location != null) {
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        LatLng latLng = new LatLng(latitude, longitude);
        myPosition = new LatLng(latitude, longitude);


        LatLng coordinate = new LatLng(latitude, longitude);
        CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(coordinate, 19);
        mMap.animateCamera(yourLocation);
    }
}

}

Dont forget to add permissions on AndroidManifest.xml.

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

In [3]: df[df['ids'].str.contains("ball")]

From the docs:

from .. import scriptA

You can do this in packages, but not in scripts you run directly. From the link above:

Note that both explicit and implicit relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports.

If you create a script that imports A.B.B, you won't receive the ValueError.

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

If you have copied & Pasted files from an old backup folder to new then its simple. Just copy the old ibdata1 into your new one. You can find it from \xampp\mysql\data

Math.min uses a simple comparison to do its thing. The only advantage to not using Math.min is to save the extra function calls, but that is a negligible saving.

If you have more than just three numbers, having a minimum method for any number of doubles might be valuable and would look something like:

public static double min(double ... numbers) {
    double min = numbers[0];
    for (int i=1 ; i<numbers.length ; i++) {
        min = (min <= numbers[i]) ? min : numbers[i];
    }
    return min;
}

For three numbers this is the functional equivalent of Math.min(a, Math.min(b, c)); but you save one method invocation.

Set up a System variable from Maven and in java use following call

System.getProperty("Key");

In JavaScript you cannot have the direct access to the filesystem. However, you can make browser to pop up a dialog window allowing the user to pick the save location. In order to do this, use the replace method with your Base64String and replace "image/png" with "image/octet-stream":

"data:image/png;base64,iVBORw0KG...".replace("image/png", "image/octet-stream");

Also, W3C-compliant browsers provide 2 methods to work with base64-encoded and binary data:

• atob()
• btoa()

Probably, you will find them useful in a way...

Here is a refactored version of what I understand you need:

window.addEventListener('DOMContentLoaded', () => {_x000D_
  const img = document.getElementById('embedImage');_x000D_
  img.src = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA' +_x000D_
    'AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO' +_x000D_
    '9TXL0Y4OHwAAAABJRU5ErkJggg==';_x000D_
_x000D_
  img.addEventListener('load', () => button.removeAttribute('disabled'));_x000D_
  _x000D_
  const button = document.getElementById('saveImage');_x000D_
  button.addEventListener('click', () => {_x000D_
    window.location.href = img.src.replace('image/png', 'image/octet-stream');_x000D_
  });_x000D_
});

In addition to Gilson PJ answer:

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

with

"scripts": {
    "build": "NODE_ENV=production webpack -p --config ./webpack.production.config.js"
},

cause that the it tries to uglify your code twice. See https://webpack.github.io/docs/cli.html#production-shortcut-p for more information.

You can fix this by removing the UglifyJsPlugin from plugins-array or add the OccurrenceOrderPlugin and remove the "-p"-flag. so one possible solution would be

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.OccurrenceOrderPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

and

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

In theory like so:

# BOLD
$ echo -e "\033[1mThis is a BOLD line\033[0m"
This is a BOLD line

# Using tput
tput bold 
echo "This" #BOLD
tput sgr0 #Reset text attributes to normal without clear.
echo "This" #NORMAL

# UNDERLINE
$ echo -e "\033[4mThis is a underlined line.\033[0m"
This is a underlined line. 

But in practice it may be interpreted as "high intensity" color instead.

See man git-add:

Data for last month-

select count(distinct switch_id)

One tip that nobody has mentioned yet is to remember to host the app on the LAN-accessible address 0.0.0.0 instead of the default localhost. Firewalls on Mac and Linux are less strict about this address compared to the default localhost address (172.0.0.1).

For example,

gatsby develop --host 0.0.0.0

yarn start --host 0.0.0.0

npm start --host 0.0.0.0

You can then access the address to connect to by entering ifconfig or ipconfig in the terminal. Then try one of the IP addresses on the left that does not end in .255 or .0

declare @xx int 
set     @xx = 3 
select @xx      
select @xx * 2  -- yields another integer  
select @xx/1    -- same
select @xx/1.0  --yields 6 decimal places 
select @xx/1.00 --       6 
select @xx * 1.0  --     1 decimal place - victory
select @xx * 1.00 --     2         places - hooray 

Also _ inserting an int into a temp_table with like decimal(10,3) _ works ok.

Neither is good.

Behaviour should be configured independent of the actual markup. For instance, in jQuery you might do something like

$('#the-element').click(function () { /* perform action here */ });

in a separate <script> block.

The advantage of this is that it

1. Separates markup and behaviour in the same way that CSS separates markup and style
2. Centralises configuration (this is somewhat a corollary of 1).
3. Is trivially extensible to include more than one argument using jQuery’s powerful selector syntax

Furthermore, it degrades gracefully (but so would using the onclick event) since you can provide the link tags with a href in case the user doesn’t have JavaScript enabled.

Of course, these arguments still count if you’re not using jQuery or another JavaScript library (but why do that?).

Basic index columns are sorted, but included columns are not sorted. This saves resources in maintaining the index, while still making it possible to provide the data in the included columns to cover a query. So, if you want to cover queries, you can put the search criteria to locate rows into the sorted columns of the index, but then "include" additional, unsorted columns with non-search data. It definitely helps with reducing the amount of sorting and fragmentation in index maintenance.

Another way to solve the issue:

If you are using the support library, you need to add the appcompat lib to the project. This link shows how to add the support lib to your project.

Assuming you have added the support lib earlier but you are getting the mentioned issue, you can follow the steps below to fix that.

1. Right click on the project and navigate to Build Path > Configure Build Path.

2. On the left side of the window, select Android. You will see something like this:

3. You can notice that no library is referenced at the moment. Now click on the Add button shown at the bottom-right side. You will see a pop up window as shown below.

4. Select the appcompat lib and press OK. (Note: The lib will be shown if you have added them as mentioned earlier). Now you will see the following window:

5. Press OK. That's it. The lib is now added to your project (notice the red mark) and the errors relating inclusion of support lib must be gone.

Also check if you have installed the Mongo as a windows service and if its running. That's also important. There might port conflict because of that.

WebMvcConfigurerAdapter will be deprecated with Spring 5. From its Javadoc:

@deprecated as of 5.0 {@link WebMvcConfigurer} has default methods (made possible by a Java 8 baseline) and can be implemented directly without the need for this adapter

As stated above, what you should do is implementing WebMvcConfigurer and overriding addInterceptors method.

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new MyCustomInterceptor());
    }
}

Object.keys(myObj).length === 0;

As there is need to just check if Object is empty it will be better to directly call a native method Object.keys(myObj).length which returns the array of keys by internally iterating with for..in loop.As Object.hasOwnProperty returns a boolean result based on the property present in an object which itself iterates with for..in loop and will have time complexity O(N2).

On the other hand calling a UDF which itself has above two implementations or other will work fine for small object but will block the code which will have severe impact on overall perormance if Object size is large unless nothing else is waiting in the event loop.

If you're storing phone numbers in a float typed column (which is a bad idea) then they are presumably all integers and could be cast to int before casting to nvarchar.

So instead of:

select cast(cast(1234567890 as float) as nvarchar(50))
1.23457e+009

You would use:

select cast(cast(cast(1234567890 as float) as int) as nvarchar(50))
1234567890

In these examples the innermost cast(1234567890 as float) is used in place of selecting a value from the appropriate column.

I really recommend that you not store phone numbers in floats though!
What if the phone number starts with a zero?

select cast(0100884555 as float)
100884555

Whoops! We just stored an incorrect phone number...

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

I found another issue, for some reason if the extensions are cached in the local AppData folder, the XNA extensions never get loaded.

You need to remove the files extensionSdks.en-US.cache and extensions.en-US.cache from the %LocalAppData%\Microsoft\VisualStudio\11.0\Extensions folder. These files are rebuilt the next time you launch

If you need access to the Visual Studio startup log to debug what's happening, run devenv.exe /log command from the C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE directory (assuming you are on a 64 bit machine). The log file generated is located here:

%AppData%\Microsoft\VisualStudio\11.0\ActivityLog.xml

Better to use android.R.drawable because it is public and documented.

You can create table script along with its data using following steps:

1. Right click on the database.
2. Select Tasks > Generate scripts ...
3. Click next.
4. Click next.
5. In Table/View Options, set Script Data to True; then click next.
6. Select the Tables checkbox and click next.
7. Select your table name and click next.
8. Click next until the wizard is done.

       * and then send a pageview to log path change.
       */
      myGoogleAnalytics.sendPageview = function() {

          $window.ga('set', 'page', $location.path());
          $window.ga('send', 'pageview');
        }
      }

      // subscribe to events
      $rootScope.$on('$viewContentLoaded', myGoogleAnalytics.sendPageview);

      return myGoogleAnalytics;
    }
  ])
  .run([
    'myGoogleAnalytics', 
    function(myGoogleAnalytics) {
        // inject self

  ]);

1. In your Android studio , at project panel , there is gear icon "Click on it".
2. Uncheck the Compact Empty Middle Packages
3. Now the package directory has been broken up i.e individual directories.
4. Select the directory you want to rename.
5. Right click on that particular directory.
6. Select refactor and then rename option.
7. The dialog box has been open up,rename it.
8. After putting new name, click on Refactor.
9. Then click on Do Refactor at bottom.
10. Then android studio will update all changes.
11. Now open build.gradle file and update the applicationId & sync it.
12. Now go to manifest file and rename the package.
13. Rebuild your Project.
14. You are done :)

There is an important and subtle issue that none of them addresses directly. There are two ways of considering type in C#: static type and run-time type.

Static type is the type of a variable in your source code. It is therefore a compile-time concept. This is the type that you see in a tooltip when you hover over a variable or property in your development environment.

You can obtain static type by writing helper generic method to let type inference take care of it for you:

   Type GetStaticType<T>(T x) { return typeof(T); }

Run-time type is the type of an object in memory. It is therefore a run-time concept. This is the type returned by the GetType() method.

An object's run-time type is frequently different from the static type of the variable, property, or method that holds or returns it. For example, you can have code like this:

object o = "Some string";

The static type of the variable is object, but at run time, the type of the variable's referent is string. Therefore, the next line will print "System.String" to the console:

Console.WriteLine(o.GetType()); // prints System.String

But, if you hover over the variable o in your development environment, you'll see the type System.Object (or the equivalent object keyword). You also see the same using our helper function from above:

Console.WriteLine(GetStaticType(o)); // prints System.Object

For value-type variables, such as int, double, System.Guid, you know that the run-time type will always be the same as the static type, because value types cannot serve as the base class for another type; the value type is guaranteed to be the most-derived type in its inheritance chain. This is also true for sealed reference types: if the static type is a sealed reference type, the run-time value must either be an instance of that type or null.

Conversely, if the static type of the variable is an abstract type, then it is guaranteed that the static type and the runtime type will be different.

To illustrate that in code:

// int is a value type
int i = 0;
// Prints True for any value of i
Console.WriteLine(i.GetType() == typeof(int));

// string is a sealed reference type
string s = "Foo";
// Prints True for any value of s
Console.WriteLine(s == null || s.GetType() == typeof(string));

// object is an unsealed reference type
object o = new FileInfo("C:\\f.txt");
// Prints False, but could be true for some values of o
Console.WriteLine(o == null || o.GetType() == typeof(object));

// FileSystemInfo is an abstract type
FileSystemInfo fsi = new DirectoryInfo("C:\\");
// Prints False for all non-null values of fsi
Console.WriteLine(fsi == null || fsi.GetType() == typeof(FileSystemInfo));

Another way to accomplish this if you still have that issue is by doing the following :

• Clear all the Table header text leave it empty.
• On the Reports “Header” section add textboxes inside a rectangle , each textbox will represent a column header for the table.
• As this rectangle is on the Reports Header section it will display on all report pages.

Thanks, Sufian.

I just built a sandbox environment with your code and it worked for me. Here is what I used:

<html>
  <head>
    <title>test</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
  </head>
  <body>
    <form id="chatTickets" method="post" action="/admin/index.cfm/">
      <input id="ticketID1" type="radio" checked="checked" value="myvalue1" name="ticketID"/>
      <input id="ticketID2" type="radio" checked="checked" value="myvalue2" name="ticketID"/>
    </form>
    <a href="#" title="Load ActiveChat" id="loadActive">Load Active</a>

    <script>
      jQuery("#loadActive").click(function() {
        //I have other code in here that runs before this function call
        writeData();
      });
      function writeData() {
        jQuery("input[name='ticketID']").each(function(i) {
            jQuery(this).attr('disabled', 'disabled');
        });
      }
    </script>
  </body>
</html>

I tested in FF3.5, moving to IE8 now. And it works fine in IE8 too. What browser are you using?

Although <input> ignores the rows attribute, you can take advantage of the fact that <textarea> doesn't have to be inside <form> tags, but can still be a part of a form by referencing the form's id:

<form method="get" id="testformid">
    <input type="submit" />
</form> 
<textarea form ="testformid" name="taname" id="taid" cols="35" wrap="soft"></textarea>

Of course, <textarea> now appears below "submit" button, but maybe you'll find a way to reposition it.

Although the accepted response is a good answer, it overlooks failure scenarios. curl will return 000 if there is an error in the request or there is a connection failure.

url='http://localhost:8080/'
status=$(curl --head --location --connect-timeout 5 --write-out %{http_code} --silent --output /dev/null ${url})
[[ $status == 500 ]] || [[ $status == 000 ]] && echo restarting ${url} # do start/restart logic

Note: this goes a little beyond the requested 500 status check to also confirm that curl can even connect to the server (i.e. returns 000).

Create a function from it:

failureCode() {
    local url=${1:-http://localhost:8080}
    local code=${2:-500}
    local status=$(curl --head --location --connect-timeout 5 --write-out %{http_code} --silent --output /dev/null ${url})
    [[ $status == ${code} ]] || [[ $status == 000 ]]
}

Test getting a 500:

failureCode http://httpbin.org/status/500 && echo need to restart

Test getting error/connection failure (i.e. 000):

failureCode http://localhost:77777 && echo need to start

Test not getting a 500:

failureCode http://httpbin.org/status/400 || echo not a failure

                      .mapToLong(p -> p.toFile().length())
                      .sum();

Try this code to download an image from a URL on Android:

DownloadManager downloadManager = (DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri = Uri.parse(imageName);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
Long reference = downloadManager.enqueue(request);

The syntax for ng if else in angular is :

<div class="case" *ngIf="data.id === '5'; else elsepart; ">
    <input type="checkbox" id="{{data.id}}" value="{{data.displayName}}" 
    data-ng-model="customizationCntrl.check[data.id1]" data-ng-checked="
    {{data.status}}=='1'" onclick="return false;">{{data.displayName}}<br>
</div>
<ng-template #elsepart>
    <div class="case">
        <input type="checkbox" id="{{data.id}}" value={{data.displayName}}"  
        data-ng-model="customizationCntrl.check[data.id]" data-ng-checked="
        {{data.status}}=='1'">{{data.displayName}}<br>
    </div> 
</ng-template>

I tried so many solutions on here that didn't work for me, only displaying some of the ports. But the following displayed All of them and their information.

        using (var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE Caption like '%(COM%'"))
        {
            var portnames = SerialPort.GetPortNames();
            var ports = searcher.Get().Cast<ManagementBaseObject>().ToList().Select(p => p["Caption"].ToString());

            var portList = portnames.Select(n => n + " - " + ports.FirstOrDefault(s => s.Contains(n))).ToList();

            foreach(string s in portList)
            {
                Console.WriteLine(s);
            }
        }
    }

Take this example, you can place it wherever you want to show it without referring to script in the footer or somewhere else like other answers

<script>new Date().getFullYear()>document.write(new Date().getFullYear());</script>

Copyright note on the footer as an example

Copyright 2010 - <script>new Date().getFullYear()>document.write(new Date().getFullYear());</script>

Maybe you could do it like this:

Don't use the model in first controller. Store data in some other shared object which could be then retrieved by second controller.

Look at this and this post. It's about the similar issue.

P.S.

You could probabbly use session scoped bean for that shared data...

Linq query:

var query = from s2 in (from s in someList group s by new { s.Column1, s.Column2 } into sg select sg) where s2.Count() > 1 select s2;

It's very easy, just run the following JPQL query:

int count = (
(Number)
    entityManager
    .createQuery(
        "select count(b) " +
        "from Book b")
    .getSingleResult()
).intValue();

The reason we are casting to Number is that some databases will return Long while others will return BigInteger, so for portability sake you are better off casting to a Number and getting an int or a long, depending on how many rows you are expecting to be counted.

The command palette tells you the colours and their order when col = somefactor. It can also be used to set the colours as well.

palette()
[1] "black"   "red"     "green3"  "blue"    "cyan"    "magenta" "yellow"  "gray"   

In order to see that in your graph you could use a legend.

legend('topright', legend = levels(iris$Species), col = 1:3, cex = 0.8, pch = 1)

You'll notice that I only specified the new colours with 3 numbers. This will work like using a factor. I could have used the factor originally used to colour the points as well. This would make everything logically flow together... but I just wanted to show you can use a variety of things.

You could also be specific about the colours. Try ?rainbow for starters and go from there. You can specify your own or have R do it for you. As long as you use the same method for each you're OK.

You can keep your initial linear layout by nesting the relative layout within the linear layout:

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView android:text="welcome" 
        android:id="@+id/TextView" 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content">
    </TextView>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <Button android:text="submit" 
            android:id="@+id/Button" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true">
        </Button>
        <EditText android:id="@+id/EditText" 
            android:layout_width="match_parent" 
            android:layout_height="wrap_content"
            android:layout_toLeftOf="@id/Button"
            android:layout_alignParentBottom="true">
        </EditText>
    </RelativeLayout>
</LinearLayout>

If you can live with the restriction that the methods of IFirst and ISecond must only interact with the contract of IFirst and ISecond (like in your example)... you can do what you ask with extension methods. In practice, this is rarely the case.

public interface IFirst {}
public interface ISecond {}

public class FirstAndSecond : IFirst, ISecond
{
}

public static MultipleInheritenceExtensions
{
  public static void First(this IFirst theFirst)
  {
    Console.WriteLine("First");
  }

  public static void Second(this ISecond theSecond)
  {
    Console.WriteLine("Second");
  }
}

///

public void Test()
{
  FirstAndSecond fas = new FirstAndSecond();
  fas.First();
  fas.Second();
}

So the basic idea is that you define the required implementation in the interfaces... this required stuff should support the flexible implementation in the extension methods. Anytime you need to "add methods to the interface" instead you add an extension method.

This is what I did on Ubuntu 18.04:

$ sudo apt install mongodb
$ mongo
> show dbs
> use admin
> db.createUser({  user: "root",  pwd: "rootpw",  roles: [ "root" ]  })  // root user can do anything
> use lefa
> db.lefa.save( {name:"test"} )
> db.lefa.find()
> show dbs
> db.createUser({  user: "lefa",  pwd: "lefapw",  roles: [ { role: "dbOwner", db: "lefa" } ]  }) // admin of a db
> exit
$ sudo vim /etc/mongodb.conf
auth = true
$ sudo systemctl restart mongodb
$ mongo -u "root" -p "rootpw" --authenticationDatabase  "admin"
> use admin
> exit
$ mongo -u "lefa" -p "lefapw" --authenticationDatabase  "lefa"
> use lefa
> exit

VBA does not have a Continue or any other equivalent keyword to immediately jump to the next loop iteration. I would suggest a judicious use of Goto as a workaround, especially if this is just a contrived example and your real code is more complicated:

For i = LBound(Schedule, 1) To UBound(Schedule, 1)
    If (Schedule(i, 1) < ReferenceDate) Then
        PrevCouponIndex = i
        Goto NextIteration
    End If
    DF = Application.Run("SomeFunction"....)
    PV = PV + (DF * Coupon / CouponFrequency)
    '....'
    'a whole bunch of other code you are not showing us'
    '....'
    NextIteration:
Next

If that is really all of your code, though, @Brian is absolutely correct. Just put an Else clause in your If statement and be done with it.

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

Almost everybody answered this. My version of printing any rails exception into logs would be:

begin
    some_statement
rescue => e
    puts "Exception Occurred #{e}. Message: #{e.message}. Backtrace:  \n #{e.backtrace.join("\n")}"
    Rails.logger.error "Exception Occurred #{e}. Message: #{e.message}. Backtrace:  \n #{e.backtrace.join("\n")}"
end

Both do different things.

The first creates an object with automatic storage duration. It is created, used, and then goes out of scope when the current block ({ ... }) ends. It's the simplest way to create an object, and is just the same as when you write int x = 0;

The second creates an object with dynamic storage duration and allows two things:

• Fine control over the lifetime of the object, since it does not go out of scope automatically; you must destroy it explicitly using the keyword delete;

• Creating arrays with a size known only at runtime, since the object creation occurs at runtime. (I won't go into the specifics of allocating dynamic arrays here.)

Neither is preferred; it depends on what you're doing as to which is most appropriate.

Use the former unless you need to use the latter.

Your C++ book should cover this pretty well. If you don't have one, go no further until you have bought and read, several times, one of these.

Good luck.

Your original code is broken, as it deletes a char array that it did not new. In fact, nothing newd the C-style string; it came from a string literal. deleteing that is an error (albeit one that will not generate a compilation error, but instead unpredictable behaviour at runtime).

Usually an object should not have the responsibility of deleteing anything that it didn't itself new. This behaviour should be well-documented. In this case, the rule is being completely broken.

In your UITableViewCell subclass, override layoutSubviews and hide the _UITableViewCellSeparatorView. Works under iOS 10.

override func layoutSubviews() {
    super.layoutSubviews()

    subviews.forEach { (view) in
        if view.dynamicType.description() == "_UITableViewCellSeparatorView" {
            view.hidden = true
        }
    }
}

readlines() will return a list of all the lines in the file, so lines is a list. You probably want something like this:

for line in f.readlines(): # Iterates through every line and looks for a match
#or
#for line in f:
    match = re.findall('[A-Z]+', line)
    print match

Or, if the file isn't too large you can grab it as as single string:

lines = f.read() # Warning: reads the FULL FILE into memory. This can be bad.
match = re.findall('[A-Z]+', lines)
print match

Here is my solution for that:

EDIT - changed code a little bit

public static <E> Iterable<E> concat(final Iterable<? extends E> list1, Iterable<? extends E> list2)
{
    return new Iterable<E>()
    {
        public Iterator<E> iterator()
        {
            return new Iterator<E>()
            {
                protected Iterator<? extends E> listIterator = list1.iterator();
                protected Boolean checkedHasNext;
                protected E nextValue;
                private boolean startTheSecond;

                public void theNext()
                {
                    if (listIterator.hasNext())
                    {
                        checkedHasNext = true;
                        nextValue = listIterator.next();
                    }
                    else if (startTheSecond)
                        checkedHasNext = false;
                    else
                    {
                        startTheSecond = true;
                        listIterator = list2.iterator();
                        theNext();
                    }
                }

                public boolean hasNext()
                {
                    if (checkedHasNext == null)
                        theNext();
                    return checkedHasNext;
                }

                public E next()
                {
                    if (!hasNext())
                        throw new NoSuchElementException();
                    checkedHasNext = null;
                    return nextValue;

                }

                public void remove()
                {
                    listIterator.remove();
                }
            };
        }
    };
}

I was not satisfied, so I finally used this:

>>> a=numpy.array([[1,2,3],[4,5,6]])
>>> a
array([[1, 2, 3],
       [4, 5, 6]])

>>> tuple(a.reshape(1, -1)[0])
(1, 2, 3, 4, 5, 6)

I don't know if it's quicker, but it looks more effective ;)

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

I known this is old, but I found a easier solution and it works on ie10, firefox and chrome:

<div id="wrapper">
  <div id="one">One</div>
  <div id="two">Two</div>
  <div id="three">Three</div>
</div> 

This is the css:

#wrapper {display:table;}
#one {display:table-footer-group;}
#three {display:table-header-group;}

And the result:

"Three"
"Two"
"One"

I found it here.

This is using the :hover pseudoelement in CSS3.

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper .text {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

#wrapper:hover .text {
visibility:visible;
}

?Demo HERE.

This instead is a way of achieving the same result by using jquery:

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper p {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

jquery code:

$('.hover').mouseover(function() {
  $('.text').css("visibility","visible");
});

$('.hover').mouseout(function() {
  $('.text').css("visibility","hidden");
});

You can put the jquery code where you want, in the body of the HTML page, then you need to include the jquery library in the head like this:

<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>

You can see the demo HERE.

When you want to use it on your website, just change the <img src /> value and you can add multiple images and captions, just copy the format i used: insert image with class="hover" and p with class="text"

Don't forget DataFrame.tail! e.g. df1.tail(10)

If you have security\requestFiltering nodes in your web.config as follows:

<security>
  <requestFiltering>
    <verbs allowUnlisted="false">
      <add verb="GET" allowed="true" />
      <add verb="POST" allowed="true" />
      <add verb="PUT" allowed="true" />
      <add verb="DELETE" allowed="true" />
      <add verb="DEBUG" allowed="true" />          
    </verbs>
  </requestFiltering>

make sure you add this as well

<add verb="OPTIONS" allowed="true" />

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

Using XmlHttpRequest you can pull up the current page and then examine the http headers of the response.

Best case is to just do a HEAD request and then examine the headers.

For some examples of doing this have a look at http://www.jibbering.com/2002/4/httprequest.html

Just my 2 cents.

The two approaches are not interchangeable. You should initialize state in the constructor when using ES6 classes, and define the getInitialState method when using React.createClass.

See the official React doc on the subject of ES6 classes.

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = { /* initial state */ };
  }
}

is equivalent to

var MyComponent = React.createClass({
  getInitialState() {
    return { /* initial state */ };
  },
});

This console warning is not an error or an actual problem — Chrome is just spreading the word about this new standard to increase developer adoption.

It has nothing to do with your code. It is something their web servers will have to support.

Release date for a fix is February 4, 2020 per: https://www.chromium.org/updates/same-site

February, 2020: Enforcement rollout for Chrome 80 Stable: The SameSite-by-default and SameSite=None-requires-Secure behaviors will begin rolling out to Chrome 80 Stable for an initial limited population starting the week of February 17, 2020, excluding the US President’s Day holiday on Monday. We will be closely monitoring and evaluating ecosystem impact from this initial limited phase through gradually increasing rollouts.

For the full Chrome release schedule, see here.

I solved same problem by adding in response header

response.setHeader("Set-Cookie", "HttpOnly;Secure;SameSite=Strict");

SameSite prevents the browser from sending the cookie along with cross-site requests. The main goal is mitigating the risk of cross-origin information leakage. It also provides some protection against cross-site request forgery attacks. Possible values for the flag are Lax or Strict.

SameSite cookies explained here

Please refer this before applying any option.

Hope this helps you.

To properly load functions from ~/.config/fish/functions

You may set only ONE function inside file and name file the same as function name + add .fish extension.

This way changing file contents reload functions in opened terminals (note some delay may occur ~1-5s)

That way if you edit either by commandline

function name; function_content; end

then

funcsave name

you have user defined functions in console and custom made in the same order.

System.Threading.Timer is a plain timer. It calls you back on a thread pool thread (from the worker pool).

System.Timers.Timer is a System.ComponentModel.Component that wraps a System.Threading.Timer, and provides some additional features used for dispatching on a particular thread.

System.Windows.Forms.Timer instead wraps a native message-only-HWND and uses Window Timers to raise events in that HWNDs message loop.

If your app has no UI, and you want the most light-weight and general-purpose .Net timer possible, (because you are happy figuring out your own threading/dispatching) then System.Threading.Timer is as good as it gets in the framework.

I'm not fully clear what the supposed 'not thread safe' issues with System.Threading.Timer are. Perhaps it is just same as asked in this question: Thread-safety of System.Timers.Timer vs System.Threading.Timer, or perhaps everyone just means that:

1. it's easy to write race conditions when you're using timers. E.g. see this question: Timer (System.Threading) thread safety

2. re-entrancy of timer notifications, where your timer event can trigger and call you back a second time before you finish processing the first event. E.g. see this question: Thread-safe execution using System.Threading.Timer and Monitor

Linux

$ is the last line, d for delete:

sed '$d' ~/path/to/your/file/name

MacOS

Equivalent of the sed -i

sed -i '' -e '$ d' ~/path/to/your/file/name

Annotate your util classes with @Ignore. This will cause JUnit not to try and run them as tests.

You can set triangle with position see this code for reference

.top-left-corner {
    width: 0px;
    height: 0px;
    border-top: 0px solid transparent;
    border-bottom: 55px solid transparent;
    border-left: 55px solid #289006;
    position: absolute;
    left: 0px;
    top: 0px;
}

I know this question is quite old, but I have found a nice solution. Basically, you pass a container layout to this function, and it will apply the font to all supported views, and recursively cicle in child layouts:

public static void setFont(ViewGroup layout)
{
    final int childcount = layout.getChildCount();
