Try with the fully qualified name for the resource:

private static final String FILENAME = "resources/skyscrapper";

For everyone that has Android problems in the string.xml, use \'\' instead of single quote.

My mistake, the resource files WERE actually copied to target/test-classes. The problem seemed to be due to spaces in my project name, e.g. Project%20Name.

I'm now loading the file as follows and it works:

org.apache.commons.io.FileUtils.toFile(myClass().getResource("resourceFile.txt")??);

Or, (taken from Java: how to get a File from an escaped URL?) this may be better (no dependency on Apache Commons):

myClass().getResource("resourceFile.txt")??.toURI();

look at this : http://docs.oracle.com/javase/6/docs/api/java/util/Properties.html#load(java.io.Reader)

the properties accept an Reader object as arguments, which you can create from an InputStream.

at the create time, you can specify the encoding of the Reader:

InputStreamReader isr = new InputStreamReader(stream, "UTF-8");

then apply this Reader to the load method :

prop.load(isr);

BTW: get the stream from .properties file :

 InputStream stream = this.class.getClassLoader().getResourceAsStream("a.properties");

BTW: get resource bundle from InputStreamReader:

ResourceBundle rb = new PropertyResourceBundle(isr);

hope this can help you !

As long as you name your resource bundle files correctly (with a .properties extension), then this works:

File file = new File("C:\\temp");
URL[] urls = {file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("myResource", Locale.getDefault(), loader);

where "c:\temp" is the external folder (NOT on the classpath) holding the property files, and "myResource" relates to myResource.properties, myResource_fr_FR.properties, etc.

I hit this issue when, for example, mapping one class to another (such as when switching to a new set of classes to represent person data). At that point, you need both classes because that is the whole point of the code--to map one to the other. And you can't rename the classes in either place (again, the job is to map, not to go change what someone else did).

Fully qualified is one way. It appears you can't actually include both import statements, because Java gets worried about which "Person" is meant, for example.

using command

npm install bootstrap --save

open .angular.json old (.angular-cli.json ) file find the "styles" add the bootstrap css file

"styles": [
       "src/styles.scss",
       "node_modules/bootstrap/dist/css/bootstrap.min.css"
],

From the docs:

You can create multidimensional arrays by nesting pairs of square brackets, where the name of the base type of the elements is contained in the innermost pair of square brackets. For example, you can create a three-dimensional array of integers using three sets of square brackets:

var array3D: [[[Int]]] = [[[1, 2], [3, 4]], [[5, 6], [7, 8]]]

When accessing the elements in a multidimensional array, the left-most subscript index refers to the element at that index in the outermost array. The next subscript index to the right refers to the element at that index in the array that’s nested one level in. And so on. This means that in the example above, array3D[0] refers to [[1, 2], [3, 4]], array3D[0][1] refers to [3, 4], and array3D[0][1][1] refers to the value 4.

The syntax and semantics are already well-defined by other excellent answers to this question. Because execution and performance are not detailed well, I will add my answer.

What is the functional difference between these 3?

I'd always considered atomic as a default quite curious. At the abstraction level we work at, using atomic properties for a class as a vehicle to achieve 100% thread-safety is a corner case. For truly correct multithreaded programs, intervention by the programmer is almost certainly a requirement. Meanwhile, performance characteristics and execution have not yet been detailed in depth. Having written some heavily multithreaded programs over the years, I had been declaring my properties as nonatomic the entire time because atomic was not sensible for any purpose. During discussion of the details of atomic and nonatomic properties this question, I did some profiling encountered some curious results.

Execution

Ok. The first thing I would like to clear up is that the locking implementation is implementation-defined and abstracted. Louis uses @synchronized(self) in his example -- I have seen this as a common source of confusion. The implementation does not actually use @synchronized(self); it uses object level spin locks. Louis's illustration is good for a high-level illustration using constructs we are all familiar with, but it's important to know it does not use @synchronized(self).

Another difference is that atomic properties will retain/release cycle your objects within the getter.

Performance

Here's the interesting part: Performance using atomic property accesses in uncontested (e.g. single-threaded) cases can be really very fast in some cases. In less than ideal cases, use of atomic accesses can cost more than 20 times the overhead of nonatomic. While the Contested case using 7 threads was 44 times slower for the three-byte struct (2.2 GHz Core i7 Quad Core, x86_64). The three-byte struct is an example of a very slow property.

Interesting side note: User-defined accessors of the three-byte struct were 52 times faster than the synthesized atomic accessors; or 84% the speed of synthesized nonatomic accessors.

Objects in contested cases can also exceed 50 times.

Due to the number of optimizations and variations in implementations, it's quite difficult to measure real-world impacts in these contexts. You might often hear something like "Trust it, unless you profile and find it is a problem". Due to the abstraction level, it's actually quite difficult to measure actual impact. Gleaning actual costs from profiles can be very time consuming, and due to abstractions, quite inaccurate. As well, ARC vs MRC can make a big difference.

So let's step back, not focussing on the implementation of property accesses, we'll include the usual suspects like objc_msgSend, and examine some real-world high-level results for many calls to a NSString getter in uncontested cases (values in seconds):

• MRC | nonatomic | manually implemented getters: 2
• MRC | nonatomic | synthesized getter: 7
• MRC | atomic | synthesized getter: 47
• ARC | nonatomic | synthesized getter: 38 (note: ARC's adding ref count cycling here)
• ARC | atomic | synthesized getter: 47

As you have probably guessed, reference count activity/cycling is a significant contributor with atomics and under ARC. You would also see greater differences in contested cases.

Although I pay close attention to performance, I still say Semantics First!. Meanwhile, performance is a low priority for many projects. However, knowing execution details and costs of technologies you use certainly doesn't hurt. You should use the right technology for your needs, purposes, and abilities. Hopefully this will save you a few hours of comparisons, and help you make a better informed decision when designing your programs.

If none of the above answers work, you can run the test in IDE, get the class path and use it in your command. Ex: If you are using Intellij IDEA, you can find it at the top of the console(screenshot below).

Clicking on the highlighted part expands and displays the complete class path.

you need to remove the references to jars inside the folder: JetBrains\IntelliJ IDEA Community Edition VERSION

java -cp "path_copied" org.testng.TestNG testng.xml

If the project is a Maven project, you can add maven surefire plugin and provide testng suite XML file path, navigate to the project directory and run the command: mvn clean install test

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.12</version>
                <configuration>
                    <suiteXmlFiles>
                        <suiteXmlFile>config/testrun_config.xml</suiteXmlFile>
                    </suiteXmlFiles>
                </configuration>
            </plugin>

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

Specify foreign key for the details tables which references to the primary key of master and set Delete rule = Cascade .

Now when u delete a record from the master table all other details table record based on the deleting rows primary key value, will be deleted automatically.

So in that case a single delete query of master table can delete master tables data as well as child tables data.

tl;dr: use OSX's native process launcher and manager, launchd.

To do so, make a launchctl daemon. You'll have full control over all aspects of the script. You can run once or keep alive as a daemon. In most cases, this is the way to go.

1. Create a .plist file according to the instructions in the Apple Dev docs here or more detail below.
2. Place in ~/Library/LaunchAgents
3. Log in (or run manually via launchctl load [filename.plist])

For more on launchd, the wikipedia article is quite good and describes the system and its advantages over other older systems.

Here's the specific plist file to run a script at login.

Updated 2017/09/25 for OSX El Capitan and newer (credit to José Messias Jr):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
   <key>Label</key>
   <string>com.user.loginscript</string>
   <key>ProgramArguments</key>
   <array><string>/path/to/executable/script.sh</string></array>
   <key>RunAtLoad</key>
   <true/>
</dict>
</plist>

Replace the <string> after the Program key with your desired command (note that any script referenced by that command must be executable: chmod a+x /path/to/executable/script.sh to ensure it is for all users).

Save as ~/Library/LaunchAgents/com.user.loginscript.plist

Run launchctl load ~/Library/LaunchAgents/com.user.loginscript.plist and log out/in to test (or to test directly, run launchctl start com.user.loginscript)

Tail /var/log/system.log for error messages.

The key is that this is a User-specific launchd entry, so it will be run on login for the given user. System-specific launch daemons (placed in /Library/LaunchDaemons) are run on boot.

If you want a script to run on login for all users, I believe LoginHook is your only option, and that's probably the reason it exists.

To try and answer your main question:

why would you use .append() rather then .after() or vice verses?

When you are manipulating the DOM with jquery the methods you use depend on the result you want and a frequent use is to replace content.

In replacing content you want to .remove() the content and replace it with new content. If you .remove() the existing tag and then try to use .append() it won't work because the tag itself has been removed, whereas if you use .after(), the new content is added 'outside' the (now removed) tag and isn't affected by the previous .remove().

I don't know about best (simplest? fastest? most readable?), but one way would be:

dict(zip([1, 2, 3, 4], [a, b, c, d]))

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

You have to consider the Turkish I problem when comparing characters/ lowercasing / uppercasing:

I suggest to convert to String and use toLowerCase with invariant culture (in most cases at least).

public final static Locale InvariantLocale = new Locale(Empty, Empty, Empty); str.toLowerCase(InvariantLocale)

See similar C# string.ToLower() and string.ToLowerInvariant()

Note: Don't use String.equalsIgnoreCase http://nikolajlindberg.blogspot.co.il/2008/03/beware-of-java-comparing-turkish.html

This works for me. There is no event.target.class function in jQuery.

You cannot display images in a console window. You need a graphical toolkit such as Tkinter, PyGTK, PyQt, PyKDE, wxPython, PyObjC or PyFLTK. There are plenty of tutorial how to create siomple windows and loading images iun python.

With Python 3 I had this problem:

 self.path = 'T:\PythonScripts\Projects\Utilities'

produced this error:

 self.path = 'T:\PythonScripts\Projects\Utilities'
            ^
 SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in
 position 25-26: truncated \UXXXXXXXX escape

the fix that worked is:

 self.path = r'T:\PythonScripts\Projects\Utilities'

It seems the '\U' was producing an error and the 'r' preceding the string turns off the eight-character Unicode escape (for a raw string) which was failing. (This is a bit of an over-simplification, but it works if you don't care about unicode)

Hope this helps someone

basicaly 2 blocks of code that do the same thing. maybe it's a bit weird example but it proves the point. SQL Server 2005:

SELECT * INTO #temp FROM master..spt_values
DECLARE @startTime DATETIME

BEGIN TRAN 

SELECT @startTime = GETDATE()
UPDATE #temp
SET number = 0
select DATEDIFF(ms, @startTime, GETDATE())

ROLLBACK 

BEGIN TRAN 
DECLARE @name VARCHAR

DECLARE tempCursor CURSOR
    FOR SELECT name FROM #temp

OPEN tempCursor

FETCH NEXT FROM tempCursor 
INTO @name

SELECT @startTime = GETDATE()
WHILE @@FETCH_STATUS = 0
BEGIN

    UPDATE #temp SET number = 0 WHERE NAME = @name
    FETCH NEXT FROM tempCursor 
    INTO @name

END 
select DATEDIFF(ms, @startTime, GETDATE())
CLOSE tempCursor
DEALLOCATE tempCursor

ROLLBACK 
DROP TABLE #temp

the single update takes 156 ms while the cursor takes 2016 ms.

You need to designate the logfile name when calling the sql loader.

sqlldr myusername/mypassword control=Billing.ctl log=Billing.log

I was running into this problem when I was calling sql loader from inside python. The following article captures all the parameters you can designate when calling sql loader http://docs.oracle.com/cd/A97630_01/server.920/a96652/ch04.htm

Starting with version 3.5.0 of Mockito and using the InlineMockMaker, you can now mock object constructions:

 try (MockedConstruction mocked = mockConstruction(A.class)) {
   A a = new A();
   when(a.check()).thenReturn("bar");
 }

Inside the try-with-resources construct all object constructions are returning a mock.

The easiest way is to use the replace method on the column. The arguments are a list of the things you want to replace (here ['ABC', 'AB']) and what you want to replace them with (the string 'A' in this case):

>>> df['BrandName'].replace(['ABC', 'AB'], 'A')
0    A
1    B
2    A
3    D
4    A

This creates a new Series of values so you need to assign this new column to the correct column name:

df['BrandName'] = df['BrandName'].replace(['ABC', 'AB'], 'A')

The first code is an example of Javascript code, which is similar, however not JSON. JSON would not have 1) comments and 2) the var keyword

You don't have any comments in your JSON, but you should remove the var and start like this:

orders: {

The [{}] notation means "object in an array" and is not what you need everywhere. It is not an error, but it's too complicated for some purposes. AssociatedDrug should work well as an object:

"associatedDrug": {
                "name":"asprin",
                "dose":"",
                "strength":"500 mg"
          }

Also, the empty object labs should be filled with something.

Other than that, your code is okay. You can either paste it into javascript, or use the JSON.parse() method, or any other parsing method (please don't use eval)

Update 2 answered:

obj.problems[0].Diabetes[0].medications[0].medicationsClasses[0].className[0].associatedDrug[0].name

returns 'aspirin'. It is however better suited for foreaches everywhere

Also adding insert option, as not mentioned yet.

std::string str("Hello World");
char ch;

str.push_back(ch);  //ch is the character to be added
OR
str.append(sizeof(ch),ch);
OR
str.insert(str.length(),sizeof(ch),ch) //not mentioned above

For Xcode 4 and higher, open the preferences (command+,) and check "Show: Line numbers" in the "Text Editing" section.

Xcode 9

Xcode 8 and below

You can pass data as the third argument to call(). Or, depending on your API, it's possible you may want to use the sixth parameter.

From the docs:

$this->call($method, $uri, $parameters, $files, $server, $content);

No, Java doesn't have something like C#'s ref and out keywords for passing by reference.

You can only pass by value in Java. Even references are passed by value. See Jon Skeet's page about parameter passing in Java for more details.

To do something similar to ref or out you would have to wrap your parameters inside another object and pass that object reference in as a parameter.

@emunsing's answer is really cool for adding multiple columns, but I couldn't get it to work for me in python 2.7. Instead, I found this works:

mydf = mydf.reindex(columns = np.append( mydf.columns.values, ['newcol1','newcol2'])

If you're doing this in an Node.js app, you can use the leap-year package:

npm install --save leap-year

Then from your app, use the following code to verify whether the provided year or date object is a leap year:

var leapYear = require('leap-year');

leapYear(2014);
//=> false 

leapYear(2016);
//=> true 

Using a library like this has the advantage that you don't have to deal with the dirty details of getting all of the special cases right, since the library takes care of that.

If you declare it like

int x;

in a header file which is then included in multiple places, you'll end up with multiple instances of x (and potentially compile or link problems).

The correct way to approach this is to have the header file say

extern int x; /* declared in foo.c */

and then in foo.c you can say

int x; /* exported in foo.h */

THen you can include your header file in as many places as you like.

<html lang="en">
<html lang="en-US">

The first lang tag only specifies a language code. The second specifies a language code, followed by a country code.

What other values can follow the dash? According to w3.org "Any two-letter subcode is understood to be a [ISO3166] country code." so does that mean any value listed under the alpha-2 code is an accepted value?

Yes, however the value may or may not have any real meaning.

<html lang="en-US"> essentially means "this page is in the US style of English." In a similar way, <html lang="en-GB"> would mean "this page is in the United Kingdom style of English."

If you really wanted to specify an invalid combination, you could. It wouldn't mean much, but <html lang="en-ES"> is valid according to the specification, as I understand it. However, that language/country combination won't do much since English isn't commonly spoken in Spain.

I mean does this somehow further help the browser to display the page?

It doesn't help the browser to display the page, but it is useful for search engines, screen readers, and other things that might read and try to interpret the page, besides human beings.

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

I tried all the above no good. So I just add a padding individually:

 #button {

    font-size: 20px;
    color: white;
    background: crimson;
    border: 2px solid rgb(37, 34, 34);
    border-radius: 10px;
    padding-top: 10px;
    padding-bottom: 10px;
    padding-right: 10px;
    padding-left: 10px;
 }

To avoid the form submition, just use required attr in the input fields.

<input type="text" required>

Or, after submit

When the form is submited, you can use str.trim() to remove white spaces form start and end of an string. I did a submit function to show you:

submitFunction(formData){

    if(!formData.foo){
        // launch an alert to say the user the field cannot be empty
        return false;
    }
    else
    {
        formData.foo = formData.foo.trim(); // removes white 
        // do your logic here
        return true;
    }

}

seems like in Angular 1.3.12 you do not need the inner ng-repeat anymore, the outer loop returns the values of the collection is a single map entry

    .black-strip
{   width:100%;
    height: 30px;       
    background-color:black; 
}

.green-strip
{   width:0%;           
    height: 30px;       
    background-color:lime;
    animation-name: progress-bar;           
    animation-duration: 4s;  
    animation-iteration-count: infinite; 
}

@keyframes progress-bar { 
    from{width:0%} 
    to{width:100%} 
}

    <div class="black-strip">
        <div class="green-strip">
        </div>

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

Within Spring Boot 2.4 it is

sec:authorize="hasAnyRole('ROLE_ADMIN')

Ensure that you have

thymeleaf-extras-springsecurity5

in your dependencies. Also make sure that you include the namespace

xmlns:sec="http://www.thymeleaf.org/extras/spring-security"

in your html...

myString = Regex.Replace(myString, " {2,}", " ");

Least amount of markup possible (you only need one span):

<p>This text is left. <span>This text is right.</span></p>

How you want to achieve the left/right styles is up to you, but I would recommend an external style on an ID or a class.

The full HTML:

<p class="split-para">This text is left. <span>This text is right.</span></p>

And the CSS:

.split-para      { display:block;margin:10px;}
.split-para span { display:block;float:right;width:50%;margin-left:10px;}

It is not at all clear what the OP meant (even after some back-and-forth in the comments), but here are two answers to possible interpretations of the question:

For interactive user input (or piped commands or redirected input)

Use raw_input in Python 2.x, and input in Python 3. (These are built in, so you don't need to import anything to use them; you just have to use the right one for your version of python.)

For example:

user_input = raw_input("Some input please: ")

More details can be found here.

So, for example, you might have a script that looks like this

# First, do some work, to show -- as requested -- that
# the user input doesn't need to come first.
from __future__ import print_function
var1 = 'tok'
var2 = 'tik'+var1
print(var1, var2)

# Now ask for input
user_input = raw_input("Some input please: ") # or `input("Some...` in python 3

# Now do something with the above
print(user_input)

If you saved this in foo.py, you could just call the script from the command line, it would print out tok tiktok, then ask you for input. You could enter bar baz (followed by the enter key) and it would print bar baz. Here's what that would look like:

$ python foo.py
tok tiktok
Some input please: bar baz
bar baz

Here, $ represents the command-line prompt (so you don't actually type that), and I hit Enter after typing bar baz when it asked for input.

For command-line arguments

Suppose you have a script named foo.py and want to call it with arguments bar and baz from the command line like

$ foo.py bar baz

(Again, $ represents the command-line prompt.) Then, you can do that with the following in your script:

import sys
arg1 = sys.argv[1]
arg2 = sys.argv[2]

Here, the variable arg1 will contain the string 'bar', and arg2 will contain 'baz'. The object sys.argv is just a list containing everything from the command line. Note that sys.argv[0] is the name of the script. And if, for example, you just want a single list of all the arguments, you would use sys.argv[1:].

You can pass vector by reference just like this:

void do_something(int el, std::vector<int> &arr){
    arr.push_back(el);
}

However, note that this function would always add a new element at the back of the vector, whereas your array function actually modifies the first element (or initializes it value).

In order to achieve exactly the same result you should write:

void do_something(int el, std::vector<int> &arr){
    if (arr.size() == 0) { // can't modify value of non-existent element
        arr.push_back(el);
    } else {
        arr[0] = el;
    }
}

In this way you either add the first element (if the vector is empty) or modify its value (if there first element already exists).

There is an easier way which works for all buttons, just change appearance of buttons in your theme, try this:

in values-21/styles.xml

<resources>
    <style name="myBaseTheme"
        parent="@android:style/Theme.Material.Light">
        <item name="android:colorPrimary">@color/bg</item>
        <item name="android:colorPrimaryDark">@color/bg_p</item>
        <item name="android:textAppearanceButton">@style/textAppearanceButton</item>
    </style>

    <style name="textAppearanceButton" parent="@android:style/TextAppearance.Material.Widget.Button">
        <item name="android:textAllCaps">false</item>
    </style>
</resources>

PS: it's recommended to follow material design's principles, you should show capitalized text in Buttons, http://www.google.com/design/spec/components/buttons.html

You can't do a bulk-update in SSIS within a dataflow task with the OOB components.

The general pattern is to identify your inserts, updates and deletes and push the updates and deletes to a staging table(s) and after the Dataflow Task, use a set-based update or delete in an Execute SQL Task. Look at Andy Leonard's Stairway to Integration Services series. Scroll about 3/4 the way down the article to "Set-Based Updates" to see the pattern.

Stage data

Set based updates

You'll get much better performance with a pattern like this versus using the OLE DB Command transformation for anything but trivial amounts of data.

If you are into third party tools, I believe CozyRoc and I know PragmaticWorks have a merge destination component.

var ie = !-[1,]; // true if IE less than 9

This hack is supported in ie5,6,7,8. It is fixed in ie9+ (so it suits demands of this question). This hack works in all IE compatibility modes.

How it works: ie engine treat array with empty element (like this [,1]) as array with two elements, instead other browsers think that there is only one element. So when we convert this array to number with + operator we do something like that: (',1' in ie / '1' in others)*1 and we get NaN in ie and 1 in others. Than we transform it to boolean and reverse value with !. Simple. By the way we can use shorter version without ! sign, but value will be reversed.

This is the shortest hack by now. And I am the author ;)

This worked for me and was as easy as adding a gradle dependancy:

https://bintray.com/seesaa/maven/opencv#

https://github.com/seesaa/opencv-android

The one caveat being that I had to use a hardware debugging device as arm emulators were running too slow for me (as AVD Manager says they will), and, as described at the repo README, this version does not include x86 or x86_64 support.

It seems to build and the suggested test:

static {
    OpenCVLoader.initDebug();
}

spits out a bunch of output that looks about right to me.

For me in datetimepicker jquery plugin format:'d/m/Y' option is worked

$("#dobDate").datetimepicker({
lang:'en',
timepicker:false,
autoclose: true,
format:'d/m/Y',
onChangeDateTime:function( ct ){
   $(".xdsoft_datetimepicker").hide();
}
});

Try this:

arr3 = Split(Join(arr1, ",") & "," & Join(arr2, ","), ",") 

You have three options:

• either you are calculating the attribute using a @Transient method
• you can also use @PostLoad entity listener
• or you can use the Hibernate specific @Formula annotation

While Hibernate allows you to use @Formula, with JPA, you can use the @PostLoad callback to populate a transient property with the result of some calculation:

@Column(name = "price")
private Double price;

@Column(name = "tax_percentage")
private Double taxes;

@Transient
private Double priceWithTaxes;

@PostLoad
private void onLoad() {
    this.priceWithTaxes = price * taxes;
}

So, you can use the Hibernate @Formula like this:

@Formula("""
    round(
       (interestRate::numeric / 100) *
       cents *
       date_part('month', age(now(), createdOn)
    )
    / 12)
    / 100::numeric
    """)
private double interestDollars;

In the head section of your html document:

<link rel="stylesheet" type="text/css" href="/path/to/ABCD.css">

Your css file should be css only and not contain any markup.

If you get time as string in format such as 1441963946053 you simply could do something as following:

//String timestamp;
Long miliseconds = Long.valueOf(timestamp);
Timestamp ti = new Timestamp(miliseconds);

For Windows Server® 2008, Windows 7, Windows Server 2003, Windows Vista®, or Windows XP run "control userpasswords2"

• Click the Start button, then click Run (Windows XP, Server 2003 or below)

• Type control userpasswords2 and press Enter on your keyboard.

Note: For Windows 7 and Windows Vista, this command will not run by typing it in the Serach box on the Start Menu - it must be run using the Run option. To add the Run command to your Start menu, right-click on it and choose the option to customize it, then go to the Advanced options. Check to option to add the Run command.

You will see a window of user details!

PostgreSQL supports regular expressions matching.

So, your example would look like

SELECT * FROM books WHERE title ~ '^\d+ ?' 

This will match a title starting with one or more digits and an optional space

As part of the uuid spec, if you generate a uuid from random it must contain a "4" as the 13th character and a "8", "9", "a", or "b" in the 17th (source).

// this makes sure that the 13th character is "4"
u[6] = (u[6] | 0x40) & 0x4F
// this makes sure that the 17th is "8", "9", "a", or "b"
u[8] = (u[8] | 0x80) & 0xBF 

To avoid this problem, we can bind to 127.0.0.1 instead of localhost:

bin/rails server -b 127.0.0.1

Open a terminal window. Type:

node -v

This will display your nodejs version.

Navigate to where you saved your script and input:

node script.js

This will run your script.

How exact do you need it to be? td.days / 365.25 will get you pretty close, if you're worried about leap years.

There is no API method to get a character from the Scanner. You should get the String using scanner.next() and invoke String.charAt(0) method on the returned String.

Scanner reader = new Scanner(System.in);
char c = reader.next().charAt(0);

Just to be safe with whitespaces you could also first call trim() on the string to remove any whitespaces.

Scanner reader = new Scanner(System.in);
char c = reader.next().trim().charAt(0);

Tensorflow also implemented functions for resizing/padding images tf.image.pad tf.pad.

padded_image = tf.image.pad_to_bounding_box(image, top_padding, left_padding, target_height, target_width)

padded_image = tf.pad(image, paddings, "CONSTANT")

These functions work just like other input-pipeline features of tensorflow and will work much better for machine learning applications.

Try this:

<img src="images/background.jpg" 

style="width:100%;height:100%;position:absolute;top:0;left:0;z-index:-5000;">

Another table that is useful is:

SELECT * FROM user_objects WHERE object_type='TRIGGER';

You can also use this to query views, indexes etc etc

It is worth to mention that with modern frameworks like reactJS, AngularJS, VueJS, etc, there are easy solutions for this problem, when dealing with fixed position elements. Examples are side panels or overlaid elements.

The technique is called a "Portal", which means that one of the components used in the app, without the need to actually extract it from where you are using it, will mount its children at the bottom of the body element, outside of the parent you are trying to avoid scrolling.

Note that it will not avoid scrolling the body element itself. You can combine this technique and mounting your app in a scrolling div to achieve the expected result.

Example Portal implementation in React's material-ui: https://material-ui-next.com/api/portal/

There's a function std::reverse in the algorithm header for this purpose.

#include <vector>
#include <algorithm>

int main() {
  std::vector<int> a;
  std::reverse(a.begin(), a.end());
  return 0;
}

Here is a simpler way to iterate and print values in vector.

for(int x: A) // for integer x in vector A
    cout<< x <<" "; 

The only character that needs escaping is <. (> is meaningless outside of a tag).

Therefore, your "magic" code is:

safestring = unsafestring.replace(/</g,'&lt;');

Some of the previous answers explain how to make the divs the same height, but the problem is that when the width is too narrow the divs won't stack, therefore you can implement their answers with one extra part. For each one you can use the CSS name given here in addition to the row class that you use, so the div should look like this if you always want the divs to be next to each other:

<div class="row row-eq-height-xs">Your Content Here</div>

For all screens:

.row-eq-height-xs {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: row;
}

For when you want to use sm:

.row-eq-height-sm {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: column;
}
@media (min-width:768px) {
    .row-eq-height-sm {
        flex-direction: row;
    }
}

For when you want to md:

.row-eq-height-md {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: column;
}
@media (min-width:992px) {
    .row-eq-height-md {
        flex-direction: row;
    }
}

For when you want to use lg:

.row-eq-height-lg {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: column;
}
@media (min-width:1200px) {
    .row-eq-height-md {
        flex-direction: row;
    }
}

EDIT Based on a comment, there is indeed a simpler solution, but you need to make sure to give column info from the largest desired width for all sizes down to xs (e.g. <div class="col-md-3 col-sm-4 col-xs-12">:

.row-eq-height {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
    flex-direction: row;
    flex-wrap: wrap;
}

I hope this helps someone. I use this bit of logic to verify if network shares are responsive before checking the individual paths. It should handle DNS names and IP addresses

A valid path in the text file would be \192.168.1.2\'folder' or \NAS\'folder'

@echo off
title Network Folder Check

pushd "%~dp0"
:00
cls

for /f "delims=\\" %%A in (Files-to-Check.txt) do set Server=%%A
    setlocal EnableDelayedExpansion
        ping -n 1 %Server% | findstr TTL= >nul 
            if %errorlevel%==1 ( 
                ping -n 1 %Server% | findstr "Reply from" | findstr "time" >nul
                    if !errorlevel!==1 (echo Network Asset %Server% Not Found & pause & goto EOF)
            )
:EOF

When you are adding a service reference

beware of namespace you are typing in:

You should append it to the name of your interface:

<client>
  <endpoint address="http://192.168.100.87:7001/soap/IMySOAPWebService"
            binding="basicHttpBinding" 
            contract="MyNamespace.IMySOAPWebService" />
</client>

What you're checking

if(isset($_POST['submit']))

but there's no variable name called "submit". well i want you to understand why it doesn't works. lets imagine if you give your submit button name delete <input type="submit" value="Submit" name="delete" /> and check if(isset($_POST['delete'])) then it works in this code you didn't give any name to submit button and checking its exist or not with isset(); function so php didn't find any variable like "submit" so its not working now try this :

<input type="submit" name="submit" value="Submit" />

You can use java.util.concurrent.TimeUnit library which internally uses Thread.sleep. The syntax should look like this :

@Test
public void testExipres(){
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExipration("foo", 1000);

    TimeUnit.MINUTES.sleep(2);

    assertNull(sco.getIfNotExipred("foo"));
}

This library provides more clear interpretation for time unit. You can use 'HOURS'/'MINUTES'/'SECONDS'.

Use .. LIMIT :pageSize OFFSET :pageStart

Where :pageStart is bound to the_page_index (i.e. 0 for the first page) * number_of_items_per_pages (e.g. 4) and :pageSize is bound to number_of_items_per_pages.

To detect for "has more pages", either use SQL_CALC_FOUND_ROWS or use .. LIMIT :pageSize OFFSET :pageStart + 1 and detect a missing last (pageSize+1) record. Needless to say, for pages with an index > 0, there exists a previous page.

If the page index value is embedded in the URL (e.g. in "prev page" and "next page" links) then it can be obtained via the appropriate $_GET item.

I hope you are trying to run the main class in this way, see screenshot:

If not, then try this way. If yes, then please make sure that your class you are trying to run has a main method, that is, the same method definition as below:

public static void main(String[] args) {
    // some code here
}

I hope this will help you.

Building on Amine's answer, create a helper like:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString CurrencyFormat(this HtmlHelper helper, string value)
    {
        var result = string.Format("{0:C2}", value);
        return new MvcHtmlString(result);
    }
}

in your view: use @Html.CurrencyFormat(model.value)

If you are doing simple formating like Standard Numeric Formats, then simple use string.Format() in your view like in the helper example above:

@string.Format("{0:C2}", model.value)

You can't kill a goroutine from outside. You can signal a goroutine to stop using a channel, but there's no handle on goroutines to do any sort of meta management. Goroutines are intended to cooperatively solve problems, so killing one that is misbehaving would almost never be an adequate response. If you want isolation for robustness, you probably want a process.

I had this problem when I reopened a project (which was developed on XCode 3.something on Leopard) after upgrading to Snow Leopard and XCode 3.2. Curious enough, it only affected some kinds of builds (emulator builds went fine, device ones gave me the error). And I have libxml2 at /usr/include, and it indeed contains libxml/tree.h.

Even the magic "Clean" did not work, but "Empty Caches..." under the "XCode" menu (between the Apple logo and File) did the trick (was that menu there in previous versions?). Beats me the reason, but after a clean there were no more complaints regarding libxml/tree.h

Maven uses variable $JAVACMD as the final java command, set it to where the java executable is will switch maven to different JDK.

In my MacOS case for some reason Cmd+Shift+L is not working while pressing the short cut on the keyboard (although it work just fine while clicking on this option in menu: Selection -> Select All Occurences). So for me pressing Cmd+FN+F2 did the trick (FN is for enabling "F2" obviously).

Btw, if you forget this shortcut just do right-click on the selection and see "Change All Occurrences" option

You can select the rows from the table you want to export in the MySQL Workbench SQL Editor. You will find an Export button in the resultset that will allow you to export the records to a CSV file, as shown in the following image:

Please also keep in mind that by default MySQL Workbench limits the size of the resultset to 1000 records. You can easily change that in the Preferences dialog:

Hope this helps.

For some applications you can use Fraction instead of floating-point numbers.

>>> from fractions import Fraction
>>> Fraction(1, 3**54)
Fraction(1, 58149737003040059690390169)

(For other applications, there's decimal, as suggested out by the other responses.)

In the next major version of the library HttpClient interface is going to extend Closeable. Until then it is recommended to use CloseableHttpClient if compatibility with earlier 4.x versions (4.0, 4.1 and 4.2) is not required.

You should have a default server for catch-all, you can return 404 or better to not respond at all (will save some bandwidth) by returning 444 which is nginx specific HTTP response that simply close the connection and return nothing

server {
    listen       80  default_server;
    server_name  _; # some invalid name that won't match anything
    return       444;
}

One of the basic principals of OO design: Encapsulation!

It gives you many benefits, one of which being that you can change the implementation of the getter/setter behind the scenes but any consumer of that value will continue to work as long as the data type remains the same.

The last couple of answers are almost correct - I have tons of apps that generate messages that need to end up with different consumers so the process is very simple.

If you want multiple consumers to the same message, do the following procedure.

Create multiple queues, one for each app that is to receive the message, in each queue properties, "bind" a routing tag with the amq.direct exchange. Change you publishing app to send to amq.direct and use the routing-tag (not a queue). AMQP will then copy the message into each queue with the same binding. Works like a charm :)

Example: Lets say I have a JSON string I generate, I publish it to the "amq.direct" exchange using the routing tag "new-sales-order", I have a queue for my order_printer app that prints order, I have a queue for my billing system that will send a copy of the order and invoice the client and I have a web archive system where I archive orders for historic/compliance reasons and I have a client web interface where orders are tracked as other info comes in about an order.

So my queues are: order_printer, order_billing, order_archive and order_tracking All have the binding tag "new-sales-order" bound to them, all 4 will get the JSON data.

This is an ideal way to send data without the publishing app knowing or caring about the receiving apps.

In a batch file solution

for /R c:\source %%f in (*.xml) do copy %%f x:\destination\

The code works as such;

for each file for in directory c:\source and subdirectories /R that match pattern (\*.xml) put the file name in variable %%f, then for each file do copy file copy %%f to destination x:\\destination\\

Just tested it here on my Windows XP computer and it worked like a treat for me. But I typed it into command prompt so I used the single %f variable name version, as described in the linked question above.

You can revert all your files under your working directory and index by typing following this command

git reset --hard <SHAsum of your commit>

You can also type

git reset --hard HEAD #your current head point

or

git reset --hard HEAD^ #your previous head point

Hope it helps

Just use

<a [ngClass]="{'disabled': your_condition}"> This a tag is disabled</a>

Example:

 <a [ngClass]="{'disabled': name=='junaid'}"> This a tag is disabled</a>

I am not familiar with, react-table, so I do not know it has direct support for selecting and deselecting (it would be nice if it had).

If it does not, with the piece of code you already have you can install the onCLick handler. Now instead of trying to attach style directly to row, you can modify state, by for instance adding selected: true to row data. That would trigger rerender. Now you only have to override how are rows with selected === true rendered. Something along lines of:

// Any Tr element will be green if its (row.age > 20) 
<ReactTable
  getTrProps={(state, rowInfo, column) => {
    return {
      style: {
        background: rowInfo.row.selected ? 'green' : 'red'
      }
    }
  }}
/>

A more duck-typing approach would be to say

foo.respond_to?(:to_str)

to_str indicates that an object's class may not be an actual descendant of the String, but the object itself is very much string-like (stringy?).

You can do the following:

foreach (Control X in this.Controls)
{
    TextBox tb = X as TextBox;
    if (tb != null)
    {
        string text = tb.Text;
        // Do something to text...
        tb.Text = string.Empty; // Clears it out...
    }
}

This issue may also occur if you have multiple versions of the same support library android-support-v4.jar. If your project is using other library projects that contain different-2 versions of the support library. To resolve the issue keep the same version of support library at each place.

I got stumped here a bit. Wanted to package some resource files into a wheel file and access them. Did the packaging using manifest file, but pip install was not installing it unless it was a sub directory. Hoping these sceen shots will help

+-- cnn_client
¦   +-- image_preprocessor.py
¦   +-- __init__.py
¦   +-- resources
¦   ¦   +-- mscoco_complete_label_map.pbtxt
¦   ¦   +-- retinanet_complete_label_map.pbtxt
¦   ¦   +-- retinanet_label_map.py
¦   +-- tf_client.py

MANIFEST.in

recursive-include cnn_client/resources *

Created a weel using standard setup.py . pip installed the wheel file. After installation checked if resources are installed. They are

ls /usr/local/lib/python2.7/dist-packages/cnn_client/resources

mscoco_complete_label_map.pbtxt
retinanet_complete_label_map.pbtxt 
 retinanet_label_map.py  

In tfclient.py to access these files. from

templates_dir = os.path.join(os.path.dirname(__file__), 'resources')
 file_path = os.path.join(templates_dir, \
            'mscoco_complete_label_map.pbtxt')
        s = open(file_path, 'r').read()

And it works.

I could not get the keypress event to fire for the enter button, and scratched my head for some time, until I read the jQuery docs:

"The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events." (https://api.jquery.com/keypress/)

I had to use the keyup or keydown event to catch a press of the enter button.

I've created a function to handle sed difference between MacOS (tested on MacOS 10.12) and other OS:

OS=`uname`
# $(replace_in_file pattern file)
function replace_in_file() {
    if [ "$OS" = 'Darwin' ]; then
        # for MacOS
        sed -i '' -e "$1" "$2"
    else
        # for Linux and Windows
        sed -i'' -e "$1" "$2"
    fi
}

Usage:

$(replace_in_file 's,MASTER_HOST.*,MASTER_HOST='"$MASTER_IP"',' "./mysql/.env")

Where:

, is a delimeter

's,MASTER_HOST.*,MASTER_HOST='"$MASTER_IP"',' is pattern

"./mysql/.env" is path to file

Using Visual Studio 2005 or 2008 when you create a project for an executable, on the properties windows inside the "Application" panel there is a check box named “Make single instance application” that you can activate to convert the application on a single instance application.

The quick and dirty way I use to export mysql output to a file is

$ mysql <database_name> --tee=<file_path>

and then use the exported output (which you can find in <file_path>) wherever I want.

Note that this is the only way you have in order to avoid databases running using the secure-file-priv option, which prevents the usage of INTO OUTFILE suggested in the previous answers:

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

std::pair already has the required comparison operators, which perform lexicographical comparisons using both elements of each pair. To use this, you just have to provide the comparison operators for types for types K and V.

Also bear in mind that std::sort requires a strict weak ordeing comparison, and <= does not satisfy that. You would need, for example, a less-than comparison < for K and V. With that in place, all you need is

std::vector<pair<K,V>> items; 
std::sort(items.begin(), items.end()); 

If you really need to provide your own comparison function, then you need something along the lines of

template <typename K, typename V>
bool comparePairs(const std::pair<K,V>& lhs, const std::pair<K,V>& rhs)
{
  return lhs.first < rhs.first;
}

Follow these steps to run your application on the device connected. 1. Change directories to the root of your Android project and execute: ant debug 2.

A static variable declared in a header file outside of the class would be file-scoped in every .c file which includes the header. That means separate copy of a variable with same name is accessible in each of the .c files where you include the header file.

A static class variable on the other hand is class-scoped and the same static variable is available to every compilation unit that includes the header containing the class with static variable.

Now answering this question.

Following scripts simulates associative arrays in shell scripts. Its simple and very easy to understand.

Map is nothing but a never ending string that has keyValuePair saved as --name=Irfan --designation=SSE --company=My:SP:Own:SP:Company

spaces are replaced with ':SP:' for values

Using Java 8 Stream to replace leading zeroes in components. This code passed all tests on interviewbit.com

public int compareVersion(String A, String B) {
    List<String> strList1 = Arrays.stream(A.split("\\."))
                                           .map(s -> s.replaceAll("^0+(?!$)", ""))
                                           .collect(Collectors.toList());
    List<String> strList2 = Arrays.stream(B.split("\\."))
                                           .map(s -> s.replaceAll("^0+(?!$)", ""))
                                           .collect(Collectors.toList());
    int len1 = strList1.size();
    int len2 = strList2.size();
    int i = 0;
    while(i < len1 && i < len2){
        if (strList1.get(i).length() > strList2.get(i).length()) return 1;
        if (strList1.get(i).length() < strList2.get(i).length()) return -1;
        int result = new Long(strList1.get(i)).compareTo(new Long(strList2.get(i)));
        if (result != 0) return result;
        i++;
    }
    while (i < len1){
        if (!strList1.get(i++).equals("0")) return 1;

    while (i < len2){
        if (!strList2.get(i++).equals("0")) return -1;
    }
    return 0;
}

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

void StartWebRequest()
{

For a start the first select has 6 columns and the second has 4 columns. Perhaps make both have the same number of columns (adding nulls?).

To assign multiple classes to an html element, include both class names within the quotations of the class attribute and have them separated by a space:

<article class="column wrapper"> 

In the above example, column and wrapper are two separate css classes, and both of their properties will be applied to the article element.

For performance issue, first data is to be written into Buffer. When buffer get full then data is written to output (File,console etc.). When buffer is partially filled and you want to send it to output(file,console) then you need to call flush() method manually in order to write partially filled buffer to output(file,console).

Use raw:

<%=raw @str >

But as @jmort253 correctly says, consider where the HTML really belongs.

Below is working solution using NgModel

Add variable

 public Phone:string;

In html add

      <input class="input-width" [(ngModel)]="Phone" (keyup)="keyUpEvent($event)" 
      type="text" class="form-control" placeholder="Enter Mobile Number">

In Ts file

   keyUpEvent(event: any) {
    const pattern = /[0-9\+\-\ ]/;  
    let inputChar = String.fromCharCode(event.keyCode);

    if (!pattern.test(inputChar)) {
      // invalid character, prevent input
      if(this.Phone.length>0)
      {
        this.Phone= this.Phone.substr(0,this.Phone.length-1);
      }
    }
  }

Suppose https://www.mozilla.org/foo.html executes the following JavaScript:

const stateObj = { foo: 'bar' };

history.pushState(stateObj, '', 'bar.html');

This will cause the URL bar to display https://www.mozilla.org/bar2.html, but won't cause the browser to load bar2.html or even check that bar2.html exists.

Use List<T>.Insert(0, item) or a LinkedList<T>.AddFirst().

I used the IntelliJ IDE and I had a similar problem and to solve I clicked in "Generate Sources and Update Folders for All Projects" in Maven tab.

Definitely not the most correct way, but if you just need a quick solution to get the date without the time and you do not wish to use a third party library this should do

    Date db = db.substring(0, 10) + db.substring(23,28);

I only needed the date for visual purposes and couldn't Joda so I substringed.

You need to do a while loop to get the result from the SQL query, like this:

require_once('db.php');  
$sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )    
FROM modul1open) ORDER BY idM1O LIMIT 1";

$result = mysql_query($sql);

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) {

    // If you want to display all results from the query at once:
    print_r($row);

    // If you want to display the results one by one
    echo $row['column1'];
    echo $row['column2']; // etc..

}

Also I would strongly recommend not using mysql_* since it's deprecated. Instead use the mysqli or PDO extension. You can read more about that here.

Now, if the repository is already existing on a remote machine, and you do not have anything locally, you do git clone instead.

The URL format is simple, it is PROTOCOL:/[user@]remoteMachineAddress/path/to/repository.git

For example, cloning a repository on a machine to which you have SSH access using the "dev" user, residing in /srv/repositories/awesomeproject.git and that machine has the ip 10.11.12.13 you do:

git clone ssh://[email protected]/srv/repositories/awesomeproject.git

Here is an example

private void doOpenFile() {
    int result = myFileChooser.showOpenDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        Path path = myFileChooser.getSelectedFile().toPath();

        try {
            String contentString = "";

            for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
                contentString += s;
            }

            jText.setText(contentString);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

private void doSaveFile() {
    int result = myFileChooser.showSaveDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        // We'll be making a mytmp.txt file, write in there, then move it to
        // the selected
        // file. This takes care of clearing that file, should there be
        // content in it.
        File targetFile = myFileChooser.getSelectedFile();

        try {
            if (!targetFile.exists()) {
                targetFile.createNewFile();
            }

            FileWriter fw = new FileWriter(targetFile);

            fw.write(jText.getText());
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

If above solutions are not working for your TextView then this will definitely work:

1. add this style

<style name="ClickableView">
    <item name="colorControlHighlight">@android:color/white</item>
    <item name="android:background">?selectableItemBackground</item>
</style>

2. use it just by

android:theme="@style/ClickableView"

As Srdjan Pejic says, you can use

<%= f.submit 'name', :class => 'button' %>

or the new syntax which would be:

<%= f.submit 'name', class: 'button' %>

The above suggestion of Ctrl+Shift+- code folds all code blocks recursively. I only wanted to fold the methods for my classes.

Code > Folding > Expand all to level > 1

I managed to achieve this by using the menu option Code > Folding > Expand all to level > 1.

I re-assigned it to Ctrl+NumPad-1 which gives me a quick way to collapse my classes down to their methods.

This works at the 'block level' of the file and assumes that you have classes defined at the top level of your file, which works for code such as PHP but not for JavaScript (nested closures etc.)

Try this:

v=spf1 ip4:abc.de.fgh.ij ip4:klm.no.pqr.st ~all

I think you should consider using IO.binread("/path/to/file") if you have a recent ruby interpreter (i.e. >= 1.9.2)

You could find IO class documentation here http://www.ruby-doc.org/core-2.1.2/IO.html

Cygwin is designed to provide a more-or-less complete POSIX environment for Windows, including an extensive set of tools designed to provide a full-fledged Linux-like platform. In comparison, MinGW and MSYS provide a lightweight, minimalist POSIX-like layer, with only the more essential tools like gcc and bash available. Because of MinGW's more minimalist approach, it does not provide the degree of POSIX API coverage Cygwin offers, and therefore cannot build certain programs which can otherwise be compiled on Cygwin.

In terms of the code generated by the two, the Cygwin toolchain relies on dynamic linking to a large runtime library, cygwin1.dll, while the MinGW toolchain compiles code to binaries that link dynamically to the Windows native C library msvcrt.dll as well as statically to parts of glibc. Cygwin executables are therefore more compact but require a separate redistributable DLL, while MinGW binaries can be shipped standalone but tend to be larger.

The fact that Cygwin-based programs require a separate DLL to run also leads to licensing restrictions. The Cygwin runtime library is licensed under GPLv3 with a linking exception for applications with OSI-compliant licenses, so developers wishing to build a closed-source application around Cygwin must acquire a commercial license from Red Hat. On the other hand, MinGW code can be used in both open-source and closed-source applications, as the headers and libraries are permissively licensed.

I use a CSS fix rather than JS to workaround my round cornered layer with transparent PNG inside

Try

.ie .whateverDivWrappingTheImage img {
background: #ffaabb; /* this should be the background color matching your design actually */
filter: chroma(#ffaabb); /* and this should match whatever value you put in background-color */
}

This may require more work on ie9 or later.

You have to be sure to use UIPickerViewDataSource and UIPickerViewDelegate protocols or it will throw an AppDelegate error as of swift 3

Also please take note of the change in syntax:

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int

is now:

public func numberOfComponents(in pickerView: UIPickerView) -> Int

The following below worked for me.

import UIkit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {

    @IBOutlet weak var textBox: UITextField!
    @IBOutlet weak var dropDown: UIPickerView!

    var list = ["1", "2", "3"]

    public func numberOfComponents(in pickerView: UIPickerView) -> Int{
        return 1
    }

    public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

        return list.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        self.view.endEditing(true)
        return list[row]
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        self.textBox.text = self.list[row]
        self.dropDown.isHidden = true
    }

    func textFieldDidBeginEditing(_ textField: UITextField) {

        if textField == self.textBox {
            self.dropDown.isHidden = false
            //if you don't want the users to se the keyboard type:

            textField.endEditing(true)
        }
    }
}

You can't. A Java array has a fixed length. If you need a resizable array, use a java.util.ArrayList<String>.

BTW, your code is invalid: you don't initialize the array before using it.

Method 1, set it in IB:

Method 2, one line of code:

navigationController?.navigationBar.barTintColor = UIColor.blackColor()

As Mingyu pointed out, there is a problem in formatting. Other than that, I would strongly recommend not using the Derived class's name while calling super() since it makes your code inflexible (code maintenance and inheritance issues). In Python 3, Use super().__init__ instead. Here is the code after incorporating these changes :

class Car(object):
    condition = "new"

    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg

class ElectricCar(Car):

    def __init__(self, battery_type, model, color, mpg):
        self.battery_type=battery_type
        super().__init__(model, color, mpg)

Thanks to Erwin Mayer for pointing out the issue in using __class__ with super()

You need to set the inflated view "Clickable" and "able to listen to click events" in your adapter class getView() method.

convertView = mInflater.inflate(R.layout.list_item_text, null);
convertView.setClickable(true);
convertView.setOnClickListener(myClickListener);

and declare the click listener in your ListActivity as follows,

public OnClickListener myClickListener = new OnClickListener() {
public void onClick(View v) {
                 //code to be written to handle the click event
    }
};

This holds true only when you are customizing the Adapter by extending BaseAdapter.

What worked for me... It seems if you install (or a dependent package installs) Microsoft.CodeDom.Providers.DotNetCompilerPlatform NuGet package it makes some web.config transforms that allow you to use C#7.x features in ASP.NET Razor pages. Whilst I found these worked fine on my local machine they didn't work on our server (even when the compiler was in the /bin/ folder).

The solution was to locate the element below and remove completely from web.config

  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
    </compilers>
  </system.codedom>

You can define and assign value as shown below in one line. I have given an example of two variables declared and assigned in single line. if the data type of multiple variables are same

 Dim recordStart, recordEnd As Integer: recordStart = 935: recordEnd = 946

Look at java.lang.BigDecimal, may solve your problem.

The difference between <pluginManagement/> and <plugins/> is that a <plugin/> under:

• <pluginManagement/> defines the settings for plugins that will be inherited by modules in your build. This is great for cases where you have a parent pom file.

• <plugins/> is a section for the actual invocation of the plugins. It may or may not be inherited from a <pluginManagement/>.

You don't need to have a <pluginManagement/> in your project, if it's not a parent POM. However, if it's a parent pom, then in the child's pom, you need to have a declaration like:

<plugins>
    <plugin>
        <groupId>com.foo</groupId>
        <artifactId>bar-plugin</artifactId>
    </plugin>
</plugins>

Notice how you aren't defining any configuration. You can inherit it from the parent, unless you need to further adjust your invocation as per the child project's needs.

For more specific information, you can check:

• The Maven pom.xml reference: Plugins

• The Maven pom.xml reference: Plugin Management

Strange behavior with MS Excel: If i export to "text based, comma-separated format (csv)" this is the mime-type I get after uploading on my webserver:

[name] => data.csv
[type] => application/vnd.ms-excel

So Microsoft seems to be doing own things again, regardless of existing standards: https://en.wikipedia.org/wiki/Comma-separated_values

Put this in the first line of your server.js (or whatever contains your main Node.js app):

require('events').EventEmitter.prototype._maxListeners = 0;

and the error goes away :)

Use

$items[] = $username;

I always just look at SHOW CREATE TABLE mydatabase.mytable.

For the database, it appears you need to look at SELECT DEFAULT_CHARACTER_SET_NAME FROM information_schema.SCHEMATA.

Try this,

<iframe id="testframe" src="about:blank" onload="if (testframe.location.href != 'about:blank') testframe_loaded()"></iframe>

All you need to do then is create the JavaScript function testframe_loaded().

I'm here because i have similar question but i find the short answers wrong and the one with the continuous "case when" is to much work and seeing anything repetitive in my code hurts my eyes. So here is the solution

SELECT --MIN(score), MAX(score),
    [score range] = CAST(ROUND(score-5,-1)AS VARCHAR) + ' - ' + CAST((ROUND(score-5,-1)+10)AS VARCHAR),
    [number of occurrences] = COUNT(*)
FROM order
GROUP BY  CAST(ROUND(score-5,-1)AS VARCHAR) + ' - ' + CAST((ROUND(score-5,-1)+10)AS VARCHAR)
ORDER BY MIN(score)

$created_date = date("Y-m-d H:i:s");
$sql = "INSERT INTO $tbl_name(created_date)VALUES('$created_date')";
$result = mysql_query($sql);

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

If one wants to get the last element in one go, he/she may use Array#splice():

lastElement = document.location.href.split('/').splice(-1,1);

Here, there is no need to store the split elements in an array, and then get to the last element. If getting last element is the only objective, this should be used.

Note: This changes the original array by removing its last element. Think of splice(-1,1) as a pop() function that pops the last element.

As per my understanding you want data in dictionary as shown below:

key1: value1-1,value1-2,value1-3....value100-1
key2: value2-1,value2-2,value2-3....value100-2
key3: value3-1,value3-2,value3-2....value100-3

for this you can use list for each dictionary keys:

case_list = {}
for entry in entries_list:
    if key in case_list:
        case_list[key1].append(value)
    else:
        case_list[key1] = [value]

I recommend you create an enum for your car colours instead of using Strings and the natural ordering of the enum will be the order in which you declare the constants.

public enum PaintColors {
    SILVER, BLUE, MAGENTA, RED
}

and

 static class ColorComparator implements Comparator<CarSort>
 {
     public int compare(CarSort c1, CarSort c2)
     {
         return c1.getColor().compareTo(c2.getColor());
     }
 }

You change the String to PaintColor and then in main your car list becomes:

carList.add(new CarSort("Ford Figo",PaintColor.SILVER));

...

Collections.sort(carList, new ColorComparator());

In order to run scripts, you should write the "python test.py" command in the command prompt, and not within the python shell. also, the test.py file should be at the path you run from in the cli.

Or maybe just use conditional chains with ternary operator. if … else if … else if … else chain.

I like this aproach better.

Here's the complete procedure to auto-indent a file with Netbeans 8.

First step is to go to Tools -> Options and click on Editor button and Formatting tab as it is shown on the following image.

When you have set your formatting options, click the Apply button and OK. Note that my example is with C++ language, but this also apply for Java as well.

The second step is to CTRL + A on the file where you want to apply your new formatting setting. Then, ALT + SHIFT + F or click on the menu Source -> Format.

Hope this will help.

Let's suppose you have two different classes:

public class Person
{
    public string Name, Email;
    
    public Person(string name, string email)
    {
        Name = name;
        Email = email;
    }
}

class Data
{
    public string Mail, SlackId;
    
    public Data(string mail, string slackId)
    {
        Mail = mail;
        SlackId = slackId;
    }
}

Now, let's Prepare data to work with:

var people = new Person[]
    {
        new Person("Sudi", "[email protected]"),
        new Person("Simba", "[email protected]"),
        new Person("Sarah", string.Empty)
    };
    
    var records = new Data[]
    {
        new Data("[email protected]", "Sudi_Try"),
        new Data("[email protected]", "Sudi@Test"),
        new Data("[email protected]", "SimbaLion")
    };

You will note that [email protected] has got two slackIds. I have made that for demonstrating how Join works.

Let's now construct the query to join Person with Data:

var query = people.Join(records,
        x => x.Email,
        y => y.Mail,
        (person, record) => new { Name = person.Name, SlackId = record.SlackId});
    Console.WriteLine(query);

After constructing the query, you could also iterate over it with a foreach like so:

foreach (var item in query)
    {
        Console.WriteLine($"{item.Name} has Slack ID {item.SlackId}");
    }

Let's also output the result for GroupJoin:

Console.WriteLine(
    
        people.GroupJoin(
            records,
            x => x.Email,
            y => y.Mail,
            (person, recs) => new {
                Name = person.Name,
                SlackIds = recs.Select(r => r.SlackId).ToArray() // You could materialize //whatever way you want.
            }
        ));

You will notice that the GroupJoin will put all SlackIds in a single group.

1. I had the same problem, and I used the UTF-8 coding for both of my files as follows:

   add @charset "UTF-8"; in CSS file and <meta charset="UTF-8"> under <head> tag in HTML file. and it worked for me.

   it makes the same encoding for both the files i.e HTML and CSS.

   You can also do the same for "UTF-16" encoding.

2. If it is still not working check for the <link type="text/css" rel="stylesheet" href="style.css"/> under <head> tag in HTML File where you should mention type="text/css"

you can also use DDMS tool which is part of android SDK it self. it helps in getting memory allocations of java code and native c/c++ code as well.

If you want multiple messages from a queue, say 10 messages, the command to use is:

rabbitmqadmin get queue=<QueueName> ackmode=ack_requeue_true count=10

If you don't want the messages requeued, just change ackmode to ack_requeue_false.

There are 2 annotations in Spring: @RequestBody and @ResponseBody. These annotations consumes, respectively produces JSONs. Some more info here.

A trick if you want to keep the order of the list:

df = pd.DataFrame({'country': ['US', 'UK', 'Germany', 'China']})
countries_to_keep = ['Germany', 'US']


ind=[df.index[df['country']==i].tolist() for i in countries_to_keep]
flat_ind=[item for sublist in ind for item in sublist]

df.reindex(flat_ind)

   country
2  Germany
0       US

Have a look at the class

org.joda.time.DateTime

This allows you to do things like:

old = new DateTime();
new = old.plusSeconds(500000);
System.out.println("Hours: " + (new.Hours() - old.Hours()));

However, your solution probably can be simpler:

You need to work out how many seconds in a day, divide your input by the result to get the days, and subtract it from the input to keep the remainder. You then need to work out how many hours in the remainder, followed by the minutes, and the final remainder is the seconds.

This is the analysis done for you, now you can focus on the code.

You need to ask what s/he means by "no hard coding", generally it means pass parameters, rather than fixing the input values. There are many ways to do this, depending on how you run your code. Properties are a common way in java.

With SSL the encryption is at the transport level, so it takes place before a request is sent.

So everything in the request is encrypted.

The following codes are my Powershell codes to determinate if some cpp or h or ml files are encodeding with ISO-8859-1(Latin-1) or UTF-8 without BOM, if neither then suppose it to be GB18030. I am a Chinese working in France and MSVC saves as Latin-1 on french computer and saves as GB on Chinese computer so this helps me avoid encoding problem when do source file exchanges between my system and my colleagues.

The way is simple, if all characters are between x00-x7E, ASCII, UTF-8 and Latin-1 are all the same, but if I read a non ASCII file by UTF-8, we will find the special character ? show up, so try to read with Latin-1. In Latin-1, between \x7F and \xAF is empty, while GB uses full between x00-xFF so if I got any between the two, it's not Latin-1

The code is written in PowerShell, but uses .net so it's easy to be translated into C# or F#

$Utf8NoBomEncoding = New-Object System.Text.UTF8Encoding($False)
foreach($i in Get-ChildItem .\ -Recurse -include *.cpp,*.h, *.ml) {
    $openUTF = New-Object System.IO.StreamReader -ArgumentList ($i, [Text.Encoding]::UTF8)
    $contentUTF = $openUTF.ReadToEnd()
    [regex]$regex = '?'
    $c=$regex.Matches($contentUTF).count
    $openUTF.Close()
    if ($c -ne 0) {
        $openLatin1 = New-Object System.IO.StreamReader -ArgumentList ($i, [Text.Encoding]::GetEncoding('ISO-8859-1'))
        $contentLatin1 = $openLatin1.ReadToEnd()
        $openLatin1.Close()
        [regex]$regex = '[\x7F-\xAF]'
        $c=$regex.Matches($contentLatin1).count
        if ($c -eq 0) {
            [System.IO.File]::WriteAllLines($i, $contentLatin1, $Utf8NoBomEncoding)
            $i.FullName
        } 
        else {
            $openGB = New-Object System.IO.StreamReader -ArgumentList ($i, [Text.Encoding]::GetEncoding('GB18030'))
            $contentGB = $openGB.ReadToEnd()
            $openGB.Close()
            [System.IO.File]::WriteAllLines($i, $contentGB, $Utf8NoBomEncoding)
            $i.FullName
        }
    }
}
Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');

This formula works for me:

// Converts CR TimeDate format to AssignDate for WeightedAverageDate calculation.

Date( Year({DWN00500.BUDDT}), Month({DWN00500.BUDDT}), Day({DWN00500.BUDDT}) ) - CDate(1899, 12, 30)

I solved this problem temporary by disabling the dfs permission.By adding below property code to conf/hdfs-site.xml

<property>
  <name>dfs.permissions</name>

</property>

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

1 - You can script sshpass's ssh command like this:

#!/bin/bash

export SSHPASS=password

nodeName is the attribute you are looking for. For example:

var elt = document.getElementById('foo');
console.log(elt.nodeName);

Note that nodeName returns the element name capitalized and without the angle brackets, which means that if you want to check if an element is an <div> element you could do it as follows:

elt.nodeName == "DIV"

While this would not give you the expected results:

elt.nodeName == "<div>"

I would use a mysqli connection to connect to the database. Here is an example:

$connection = new mysqli("127.0.0.1", "username", "password", "database_name", 3306);

The next step is to select the information. In your case I would do:

$query = $connection->query("SELECT `names` FROM `Customers`;");

And finally we make an array from all these names by typing:

$array = Array();
while($result = $query->fetch_assoc()){
    $array[] = $result['names'];
}

print_r($array);

So what I've done in this code: I selected all names from the table using a mysql query. Next I use a while loop to check if the $query has a next value. If so the while loop continues and adds that value to the array '$array'. Else the loop stops. And finally I print the array using the 'print_r' method so you can see it all works. I hope this was helpful.

Here is the solution for c# MVC:

1. First : Create a custom attribute and override method like this:

   public class CultureAttribute : ActionFilterAttribute
   {
       public override void OnActionExecuting(ActionExecutingContext filterContext)
       {
           // Retreive culture from GET
           string currentCulture = filterContext.HttpContext.Request.QueryString["culture"];
   
           // Also, you can retreive culture from Cookie like this :
           //string currentCulture = filterContext.HttpContext.Request.Cookies["cookie"].Value;
   
           // Set culture
           Thread.CurrentThread.CurrentCulture = new CultureInfo(currentCulture);
           Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(currentCulture);
       }
   }
   

2. Second : In App_Start, find FilterConfig.cs, add this attribute. (this works for WHOLE application)

   public class FilterConfig
   {
       public static void RegisterGlobalFilters(GlobalFilterCollection filters)
       {
           // Add custom attribute here
           filters.Add(new CultureAttribute());
       }
   }    
   

That's it !

If you want to define culture for each controller/action in stead of whole application, you can use this attribute like this:

[Culture]
public class StudentsController : Controller
{
}

Or:

[Culture]
public ActionResult Index()
{
    return View();
}

Just create a symlink in your src folder for the namespace pointing to the folder containing your classes...

ln -s ../src/AppName ./src/AppName

Your autoload in composer will look the same...

"autoload": {
    "psr-0": {"AppName": "src/"}
}

And your AppName namespaced classes will start a directory up from your current working directory in a src folder now... that should work.

The example you are referring to is called Upcasting in java.

It creates a subclass object with a super class variable pointing to it.

The variable does not change, it is still the variable of the super class but it is pointing to the object of subclass.

For example lets say you have two classes Machine and Camera ; Camera is a subclass of Machine

class Machine{

    public void start(){

        System.out.println("Machine Started");
    }
}

class Camera extends Machine{
     public void start(){

            System.out.println("Camera Started");
        }
     public void snap(){
         System.out.println("Photo taken");
     }
 }
Machine machine1 = new Camera();
machine1.start();

If you execute the above statements it will create an instance of Camera class with a reference of Machine class pointing to it.So, now the output will be "Camera Started" The variable is still a reference of Machine class. If you attempt machine1.snap(); the code will not compile

The takeaway here is all Cameras are Machines since Camera is a subclass of Machine but all Machines are not Cameras. So you can create an object of subclass and point it to a super class refrence but you cannot ask the super class reference to do all the functions of a subclass object( In our example machine1.snap() wont compile). The superclass reference has access to only the functions known to the superclass (In our example machine1.start()). You can not ask a machine reference to take a snap. :)

This expands on the answer by Denis Bubnov.

I used this to find child values of array elements—namely if there was a anchor field in paragraphs on a Drupal 8 site to build a table of contents.

{% set count = 0 %}
{% for anchor in items %}
    {% if anchor.content['#paragraph'].field_anchor_link.0.value %}
        {% set count = count + 1 %}
    {% endif %}
{% endfor %}

{% if count > 0 %}
 ---  build the toc here --
{% endif %}

In a number of cases the performance impact of SSL handshakes will be mitigated by the fact that the SSL session can be cached on both ends (desktop and server). On Windows machines for example the SSL session can be cached for up to 10 hours. See http://support.microsoft.com/kb/247658/EN-US . Some SSL accelerators will also have parameters allowing you to tune the time the session is cached.

Another impact to consider is that static content served over HTTPS will not be cached by proxies, and this may reduce performance across multiple users accessing the site over the same proxy. This can be mitigated by the fact that static content will be cached at desktops as well, Internet Explorer versions 6 and 7 cache cacheable HTTPS static content unless instructed to do otherwise (Tools Menu/Internet Options/Advanced/Security/Do not save encrypted pages to disk).

The dialog needs to be started only after the window states of the Activity are initialized This happens only after onresume.

So call

runOnUIthread(new Runnable(){

    showInfoMessageDialog("Please check your network connection","Network Alert");
});

in your OnResume function. Do not create dialogs in OnCreate
Edit:

use this

Handler h = new Handler();

h.postDelayed(new Runnable(){

        showInfoMessageDialog("Please check your network connection","Network Alert");
    },500);

in your Onresume instead of showonuithread

Password boxes are also textboxes, so if you need them too:

$("input[type='text'], textarea, input[type='password']").css({width: "90%"});

and while file-input is a bit different, you may want to include them too (eg. for visual consistency):

$("input[type='text'], textarea, input[type='password'], input[type='file']").css({width: "90%"});

This is easier to read for me:

<input type="radio" name="rWF" id="rWF" value=1  <?php if ($WF == '1') {echo ' checked ';} ?> />Water Fall</label>
<input type="radio" name="rWF" id="rWF" value=0 <?php if ($WF == '0') {echo ' checked ';} ?> />nope</label>

You can also combine es6 and stateless functions to get a much cleaner result:

import Dashboard from './Dashboard';
import Comments from './Comments';

let dashboardWrapper = () => <Dashboard {...props} />,
    commentsWrapper = () => <Comments {...props} />,
    index = () => <div>
        <header>Some header</header>
        <RouteHandler />
        {this.props.children}
    </div>;

routes = {
    component: index,
    path: '/',
    childRoutes: [
      {
        path: 'comments',
        component: dashboardWrapper
      }, {
        path: 'dashboard',
        component: commentsWrapper
      }
    ]
}

Don't forget to handle errors! The following code is based on Augusto Roman's answer.

var http = require('http');
var fs = require('fs');

var download = function(url, dest, cb) {
  var file = fs.createWriteStream(dest);
  var request = http.get(url, function(response) {
    response.pipe(file);
    file.on('finish', function() {
      file.close(cb);  // close() is async, call cb after close completes.
    });
  }).on('error', function(err) { // Handle errors
    fs.unlink(dest); // Delete the file async. (But we don't check the result)
    if (cb) cb(err.message);
  });
};

WordPress overrides PHP's memory limit to 256M, with the assumption that whatever it was set to before is going to be too low to render the dashboard. You can override this by defining WP_MAX_MEMORY_LIMIT in wp-config.php:

define( 'WP_MAX_MEMORY_LIMIT' , '512M' );

I agree with DanFromGermany, 256M is really a lot of memory for rendering a dashboard page. Changing the memory limit is really putting a bandage on the problem.

You need to execute this as a dynamic sp like

DECLARE @ExcludedList VARCHAR(MAX)

SET @ExcludedList = '3,4,22,6014'
declare @sql nvarchar(Max)

Set @sql='SELECT * FROM [A] WHERE Id NOT IN ('+@ExcludedList+')'

exec sp_executesql @sql

Add hidden attribute:

<select>
    <option value="" selected disabled hidden>Please select</option>
    <option value="">A</option>
    <option value="">B</option>
    <option value="">C</option>
</select>

Specify the width of the table:

table
{
    table-layout: fixed;
    width: 100px;
}

Change the plugin to no longer apply the style. That would be much better than removing the style there-after.

None of the above solutions alone worked for me. On Windows 7 this worked:

Install Rapid Environment Editor and remove any entries for node, npm, angular-cli or @angular/cli

Uninstall node.js and reinstall. Run Rapid Environment Editor again and make sure node.js and npm are in your System or User path. Uninstall any existing ng versions with:

npm uninstall -g angular-cli

npm uninstall -g @angular/cli

npm cache clean

Delete the C:\Users\YOU\AppData\Roaming\npm\node_modules\@angular folder.

Reboot, then, finally, run:

npm install -g @angular/cli

Then hold your breath and run ng -v. If you're lucky, you'll get some love. Hold your breath henceforward every time you run the ng command, because 'command not found' has magically reappeared for me several times after ng was running fine and I thought the problem was solved.

you can use CHARINDEX in t-sql.

select * from table where CHARINDEX(url, 'http://url.com/url?url...') > 0

The solution works fine (thanks!), but if you want to avoid casting and leave the low level work to the JDK, you can use a DataOutputStream to write your int's and a DataInputStream to read them back in. They are automatically treated as unsigned bytes then:

For converting int's to binary bytes;

ByteArrayOutputStream bos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(bos);
int val = 250;
dos.write(byteVal);
...
dos.flush();

Reading them back in:

// important to use a (non-Unicode!) encoding like US_ASCII or ISO-8859-1,
// i.e., one that uses one byte per character
ByteArrayInputStream bis = new ByteArrayInputStream(
   bos.toString("ISO-8859-1").getBytes("ISO-8859-1"));
DataInputStream dis = new DataInputStream(bis);
int byteVal = dis.readUnsignedByte();

Esp. useful for handling binary data formats (e.g. flat message formats, etc.)

if(navigator.app){
        navigator.app.exitApp();
}else if(navigator.device){
        navigator.device.exitApp();
}

This is my solution, it's not that tricky and allow you to use it for several markup throught a simple ng-class directive. Like so you can choose the class and the scrollPos for each case.

Your App.js :

angular.module('myApp',[])
    .controller('mainCtrl',function($window, $scope){
        $scope.scrollPos = 0;

        $window.onscroll = function(){
            $scope.scrollPos = document.body.scrollTop || document.documentElement.scrollTop || 0;
            $scope.$apply(); //or simply $scope.$digest();
        };
    });

Your index.html :

<html ng-app="myApp">
    <head></head>
    <body>
        <section ng-controller="mainCtrl">
            <p class="red" ng-class="{fix:scrollPos >= 100}">fix me when scroll is equals to 100</p>
            <p class="blue" ng-class="{fix:scrollPos >= 150}">fix me when scroll is equals to 150</p>
        </section>
    </body>
</html>

working JSFiddle here

EDIT :

As $apply() is actually calling $rootScope.$digest() you can directly use $scope.$digest() instead of $scope.$apply() for better performance depending on context.
Long story short : $apply() will always work but force the $digest on all scopes that may cause perfomance issue.

If you want to change the format for all dates you can add a builder customizer. Here is an example of a bean that converts dates to ISO 8601:

@Bean
public Jackson2ObjectMapperBuilderCustomizer jsonCustomizer() {
    return new Jackson2ObjectMapperBuilderCustomizer() {
        @Override
        public void customize(Jackson2ObjectMapperBuilder builder) {
            builder.dateFormat(new ISO8601DateFormat());        
        }           
    };
}

It's just a basic operation.

Remember when you learned to divide. In the beginning we solved 9/6 = 1 with remainder 3.

9 / 6 == 1  //true
9 % 6 == 3 // true

The /-operator in combination with the %-operator are used to retrieve those values.

div#father {
    position: relative;
}
div#son1 {
    position: absolute;
    /* put your coords here */
}
div#son2 {
    position: absolute;
    /* put your coords here */
}

        XmlWriterSettings settings = new XmlWriterSettings
        {
            OmitXmlDeclaration = true
        };

        XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
        ns.Add("", "");

        StringBuilder sb = new StringBuilder();

        XmlSerializer xs = new XmlSerializer(typeof(BankingDetails));

        using (XmlWriter xw = XmlWriter.Create(sb, settings))
        {
            xs.Serialize(xw, model, ns);
            xw.Flush();
            return sb.ToString();
        }

Any chance you're looking for the !important rule? It doesn't undo all declarations but it provides a way to override them.

"When an !important rule is used on a style declaration, this declaration overrides any other declaration made in the CSS, wherever it is in the declaration list. Although, !important has nothing to do with specificity."

Thought I'd update this with a dplyr solution

library(dplyr)    
filter(studentdata, Drink == "water")

prefix the comment with a single-quote. there is no need for an "end" tag.

'this is a comment

Extend to multiple lines using the line-continuation character, _:

'this is a multi-line _
   comment

This is an option in the toolbar to select a line(s) of code and comment/uncomment:

I was just having this problem on Windows 10 and the issue in my case was that I was just running psql and it was defaulting to trying to log in with my Windows username ("Nathan"), but there was no PostgreSQL user with that name, and it wasn't telling me that.

So the solution was to run psql -U postgres rather than just psql, and then the password I entered at installation worked.

I had the same problem. I was using swagger like below mentioned pattern i.e. "../swagger/v1/swagger.json" because I am using IIS Express.Later than I change it to "/swagger/v1/swagger.json"and clean,rebuild the solution worked for me.
