AccountList.Split("\r\n");

I used this code:

public static async Task<IEnumerable<TResult>> SelectAsync<TSource,TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> method)
{
      return await Task.WhenAll(source.Select(async s => await method(s)));
}

like this:

var result = await sourceEnumerable.SelectAsync(async s=>await someFunction(s,other params));

Try this :

$obj = @{
    SomeProp = "Hello"
}

Write-Host "Property Value is $($obj."SomeProp")"

Another way to do this:

1. create another branch
2. checkout the previous commit on that branch using "git checkout"
3. push the new branch.
4. delete the old branch & push the delete (use git push origin --delete <branch_name>)
5. rename the new branch into the old branch
6. push again.

Do simultaneous work on the dev branch. What happens is that in your scenario the feature branch moves forward from the tip of the dev branch, but the dev branch does not change. It's easier to draw as a straight line, because it can be thought of as forward motion. You made it to point A on dev, and from there you simply continued on a parallel path. The two branches have not really diverged.

Now, if you make a commit on dev, before merging, you will again begin at the same commit, A, but now features will go to C and dev to B. This will show the split you are trying to visualize, as the branches have now diverged.

*-----*Dev-------*Feature

Versus

       /----*DevB
*-----*DevA
       \----*FeatureC

Based on fnord's answer, here is a Unity3D version with added ranges :

Code :

// golden angle in radians
static float Phi = Mathf.PI * ( 3f - Mathf.Sqrt( 5f ) );
static float Pi2 = Mathf.PI * 2;

public static Vector3 Point( float radius , int index , int total , float min = 0f, float max = 1f , float angleStartDeg = 0f, float angleRangeDeg = 360 )
{
    // y goes from min (-) to max (+)
    var y = ( ( index / ( total - 1f ) ) * ( max - min ) + min ) * 2f - 1f;

    // golden angle increment
    var theta = Phi * index ; 
        
    if( angleStartDeg != 0 || angleRangeDeg != 360 )
    {
        theta = ( theta % ( Pi2 ) ) ;
        theta = theta < 0 ? theta + Pi2 : theta ;
            
        var a1 = angleStartDeg * Mathf.Deg2Rad;
        var a2 = angleRangeDeg * Mathf.Deg2Rad;
            
        theta = theta * a2 / Pi2 + a1;
    }

    // https://stackoverflow.com/a/26127012/2496170
    
    // radius at y
    var rY = Mathf.Sqrt( 1 - y * y ); 
    
    var x = Mathf.Cos( theta ) * rY;
    var z = Mathf.Sin( theta ) * rY;

    return  new Vector3( x, y, z ) * radius;
}

I tried most of the other answers on this question here and came to find that most of the services used were defunct except one.

Here is a script that should do the trick and download only a minimal amount of information:

#!/usr/bin/env python

import urllib
import re

def get_external_ip():
    site = urllib.urlopen("http://checkip.dyndns.org/").read()
    grab = re.findall('([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)', site)
    address = grab[0]
    return address

if __name__ == '__main__':
  print( get_external_ip() )

I guess you are looking for brace expansion:

cp /home/ankur/folder/{file1,file2} /home/ankur/dest

take a look here, it would be helpful for you if you want to handle multiple files once :

http://www.tldp.org/LDP/abs/html/globbingref.html

tab completion with zsh...

Most of the times, using a List would suffice. A List uses an internal array to handle its data, and automatically resizes the array when adding more elements to the List than its current capacity, which makes it more easy to use than an array, where you need to know the capacity beforehand.

See http://msdn.microsoft.com/en-us/library/ms379570(v=vs.80).aspx#datastructures20_1_topic5 for more information about Lists in C# or just decompile System.Collections.Generic.List<T>.

If you need multidimensional data (for example using a matrix or in graphics programming), you would probably go with an array instead.

As always, if memory or performance is an issue, measure it! Otherwise you could be making false assumptions about the code.

Now NgForm supports two methods: .reset() vs .resetForm() the latter also changes the submit state of the form to false reverting form and its controls to initial states.

This worked for me:

curl -u $username:$api_token -FSubmit=Build 'http://<jenkins-server>/job/<job-name>/buildWithParameters?environment='

API token can be obtained from Jenkins user configuration.

Have same issue on mac, you probably need to

brew install postgresql

then you can run

pip install psycopg2

The brew will fix PATH issue for you

this solution works for me at least.

Just stumbled upon this and thought I would suggest my solution. I typically like to use the built in functionality of assigning a range to an multi-dim array (I guess it's also the JS Programmer in me).

I frequently write code like this:

Sub arrayBuilder()

myarray = Range("A1:D4")

'unlike most VBA Arrays, this array doesn't need to be declared and will be automatically dimensioned

For i = 1 To UBound(myarray)

    For j = 1 To UBound(myarray, 2)

    Debug.Print (myarray(i, j))

    Next j

Next i

End Sub

Assigning ranges to variables is a very powerful way to manipulate data in VBA.

jQuery Templates is an example of something that uses this method to store HTML that will not be rendered directly (that’s the whole point) inside other HTML: http://api.jquery.com/jQuery.template/

I was having the same "Class [class name] not found" error message, but it wasn't a namespace issue. All my namespaces were set up correctly. I even tried composer dump-autoload and it didn't help me.

Surprisingly (to me) I then did composer dump-autoload -o which according to Composer's help, "optimizes PSR0 and PSR4 packages to be loaded with classmaps too, good for production." Somehow doing it that way got composer to behave and include the class correctly in the autoload_classmap.php file.

You could use

Calendar cal = Calendar.getInstance();
cal.setTime(beginupd);
long millis = cal.getTimeInMillis();

Maybe you want to track the remote branch with a local branch:

1. Create a new local branch: git branch new-local-branch
2. Set this newly created branch to track the remote branch: git branch --set-upstream-to=origin/remote-branch new-local-branch
3. Enter into this branch: git checkout new-local-branch
4. Pull all the contents of the remote branch into the local branch: git pull

Run this command:

composer install --ignore-platform-reqs

or

composer update --ignore-platform-reqs

You need httpclient.jar and httpcore.jar. You can download them from here.

I had to go into windows explorer and delete the bin/debug folder as well as the obj/debug folders. Then I cleaned & rebuilt the project.

You should just use Spread operator:

var myMap = new Map([["thing1", 1], ["thing2", 2], ["thing3", 3]]);_x000D_
_x000D_
var newArr = [...myMap].map(value => value[1] + 1);_x000D_
console.log(newArr); //[2, 3, 4]_x000D_
_x000D_
var newArr2 = [for(value of myMap) value = value[1] + 1];_x000D_
console.log(newArr2); //[2, 3, 4]

find . -type d -print0 | xargs -0 -n 1 my_command

            claz.getRawType();
            throw new RuntimeException("Shouldnt come here");
        }catch (RuntimeException ex){

        }
    }

    static void equals(Object a, Object b) {
        if (!a.equals(b)) {
            throw new RuntimeException("Test failed. " + a + " != " + b);
        }
    }

More info here. But again, it is almost impossible to retrieve for:

class SomeClass<T> extends CaptureType<T>{}
SomeClass<String> claz = new SomeClass<>();

where it gets erased.

Try this only if you are ok with uninstalling python.

I uninstalled python using

brew uninstall python

then later installed using

brew install python

then it worked!

I shared two solutions depending on your needs:

<style type="text/css" ref="stylesheet">
  .border-inside-box {
    border: 1px solid black;
  }
  .border-inside-box-v1 {
    outline: 1px solid black; /* 'border-radius' not available */
  }
  .border-outside-box-v2 {
    box-shadow: 0 0 0 1px black; /* 'border-style' not available (dashed, solid, etc) */
  }
</style>

A complete pywin32 example using loop or subthread

After working on this on and off for a few days, here is the answer I would have wished to find, using pywin32 to keep it nice and self contained.

This is complete working code for one loop-based and one thread-based solution. It may work on both python 2 and 3, although I've only tested the latest version on 2.7 and Win7. The loop should be good for polling code, and the tread should work with more server-like code. It seems to work nicely with the waitress wsgi server that does not have a standard way to shut down gracefully.

I would also like to note that there seems to be loads of examples out there, like this that are almost useful, but in reality misleading, because they have cut and pasted other examples blindly. I could be wrong. but why create an event if you never wait for it?

That said I still feel I'm on somewhat shaky ground here, especially with regards to how clean the exit from the thread version is, but at least I believe there are nothing misleading here.

To run simply copy the code to a file and follow the instructions.

update:

Use a simple flag to terminate thread. The important bit is that "thread done" prints.
For a more elaborate example exiting from an uncooperative server thread see my post about the waitress wsgi server.

When numbers, dates and times are formatted into strings or parsed from strings a culture is used to determine how it is done. E.g. in the dominant en-US culture you have these string representations:

• 1,000,000.00 - one million with a two digit fraction
• 1/29/2013 - date of this posting

In my culture (da-DK) the values have this string representation:

• 1.000.000,00 - one million with a two digit fraction
• 29-01-2013 - date of this posting

In the Windows operating system the user may even customize how numbers and date/times are formatted and may also choose another culture than the culture of his operating system. The formatting used is the choice of the user which is how it should be.

So when you format a value to be displayed to the user using for instance ToString or String.Format or parsed from a string using DateTime.Parse or Decimal.Parse the default is to use the CultureInfo.CurrentCulture. This allows the user to control the formatting.

However, a lot of string formatting and parsing is actually not strings exchanged between the application and the user but between the application and some data format (e.g. an XML or CSV file). In that case you don't want to use CultureInfo.CurrentCulture because if formatting and parsing is done with different cultures it can break. In that case you want to use CultureInfo.InvariantCulture (which is based on the en-US culture). This ensures that the values can roundtrip without problems.

The reason that ReSharper gives you the warning is that some application writers are unaware of this distinction which may lead to unintended results but they never discover this because their CultureInfo.CurrentCulture is en-US which has the same behavior as CultureInfo.InvariantCulture. However, as soon as the application is used in another culture where there is a chance of using one culture for formatting and another for parsing the application may break.

So to sum it up:

• Use CultureInfo.CurrentCulture (the default) if you are formatting or parsing a user string.
• Use CultureInfo.InvariantCulture if you are formatting or parsing a string that should be parseable by a piece of software.
• Rarely use a specific national culture because the user is unable to control how formatting and parsing is done.

try:
    value = raw_input()
    do_stuff(value) # next line was found 
except (EOFError):
   break #end of file reached

This seems to be proper usage of raw_input when dealing with the end of the stream of input from piped input. [Refer this post][1]

You could use an <a> tag with different styles:

a:link    { }
a:visited { }
a:hover   { }
a:active  { }

I'd recommend using that in conjunction with CSS sprites: https://css-tricks.com/css-sprites/

Another related problem occurs if you have multiple spaces in between inputs:

> a <- "  a string         with lots   of starting, inter   mediate and trailing   whitespace     "

You can then easily split this string into "real" tokens using a regular expression to the split argument:

> strsplit(a, split=" +")
[[1]]
 [1] ""           "a"          "string"     "with"       "lots"
 [6] "of"         "starting,"  "inter"      "mediate"    "and"
[11] "trailing"   "whitespace"

Note that if there is a match at the beginning of a (non-empty) string, the first element of the output is ‘""’, but if there is a match at the end of the string, the output is the same as with the match removed.

Different case with same error (backing up to external drive), the issue was that I'd set up the remote repo with clone. Works every time if you set the remote repo up with bare initially

cd F:/backups/dir
git init --bare
cd C:/working/dir
git remote add backup F:/backups/dir
git push backup master

From the oracle documentation, the below query explains it better

INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;

You can read this link

Your query would be as follows

//just the concept    
    INSERT INTO quotedb
    (COLUMN_NAMES) //seperated by comma
    SELECT COLUMN_NAMES FROM tickerdb,quotedb WHERE quotedb.ticker = tickerdb.ticker

Note: Make sure the columns in insert and select are in right position as per your requirement

Hope this helps!

flatMap transform the items emitted by an Observable into new Observables, then flattens the emissions from those into a single Observable.

Check out the scenario below where get("posts") returns an Observable that is "flattened" by flatMap.

myObservable.map(e => get("posts")).subscribe(o => console.log(o));
// this would log Observable objects to console.  

myObservable.flatMap(e => get("posts")).subscribe(o => console.log(o));
// this would log posts to console.

I am having the similar issues with multiple modules in application. A component can be created to any module so before creating a component we have to specify the name of the particular module.

'ng generate component newCompName --module= specify name of module'

You are setting it't type as submit. That means that browser should post your <form> data to the server.

In fact a tag has no type attribute according to w3schools.

So remote type attribute and it should work for you.

Use GNU passwd stdin flag.

From the man page:

   --stdin
          This option is used to indicate that passwd should read the new password from standard input, which can be a pipe.

NOTE: Only for root user.

Example

$ adduser foo 
$ echo "NewPass" |passwd foo --stdin
Changing password for user foo.
passwd: all authentication tokens updated successfully.

Alternatively you can use expect, this simple code will do the trick:

#!/usr/bin/expect
spawn passwd foo
expect "password:"
send "Xcv15kl\r"
expect "Retype new password:"
send "Xcv15kl\r"
interact

Results

$ ./passwd.xp 
spawn passwd foo
Changing password for user foo.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

I often find myself utilizing the --build-arg option for this purpose. For example after putting the following in the Dockerfile:

ARG SSH_KEY
RUN echo "$SSH_KEY" > /root/.ssh/id_rsa

You can just do:

docker build -t some-app --build-arg SSH_KEY="$(cat ~/file/outside/build/context/id_rsa)" .

But note the following warning from the Docker documentation:

Warning: It is not recommended to use build-time variables for passing secrets like github keys, user credentials etc. Build-time variable values are visible to any user of the image with the docker history command.

In your terminal run: docker exec -it container_name /bin/bash Then: mysql

Assuming a simple case, where your field is public:

List list; // from your method
for(Object x : list) {
    Class<?> clazz = x.getClass();
    Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
    Object fieldValue = field.get(x);
}

But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).

If you can change your method to return a List<Foo>, this becomes very easy because the iterator then can give you type information:

List<Foo> list; //From your method
for(Foo foo:list) {
    Object fieldValue = foo.fieldName;
}

Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...

List list;
for(Object x: list) {
   if( x instanceof Foo) {
      Object fieldValue = ((Foo)x).fieldName;
   }
}

No reflection needed :)

keyCodes are different from the ASCII values. For a complete keyCode reference, see http://unixpapa.com/js/key.html

For example, Numpad numbers have keyCodes 96 - 105, which corresponds to the beginning of lowercase alphabet in ASCII. This could lead to problems in validating numeric input.

Try this:

import java.util.*;

public class SimpleCacheManager {

    private static SimpleCacheManager instance;
    private static Object monitor = new Object();
    private Map<String, Object> cache = Collections.synchronizedMap(new HashMap<String, Object>());

    private SimpleCacheManager() {
    }

    public void put(String cacheKey, Object value) {
        cache.put(cacheKey, value);
    }

    public Object get(String cacheKey) {
        return cache.get(cacheKey);
    }

    public void clear(String cacheKey) {
        cache.put(cacheKey, null);
    }

    public void clear() {
        cache.clear();
    }

    public static SimpleCacheManager getInstance() {
        if (instance == null) {
            synchronized (monitor) {
                if (instance == null) {
                    instance = new SimpleCacheManager();
                }
            }
        }
        return instance;
    }

}

This is how I did it in React:

import MyPDF from '../path/to/file.pdf';
<a href={myPDF} download="My_File.pdf"> Download Here </a>

It's important to override the default file name with download="name_of_file_you_want.pdf" or else the file will get a hash number attached to it when you download.

We demonstrate features of lmfit while solving both problems.

Given

import lmfit

import numpy as np

import matplotlib.pyplot as plt


%matplotlib inline
np.random.seed(123)

# General Functions
def func_log(x, a, b, c):
    """Return values from a general log function."""
    return a * np.log(b * x) + c


# Data
x_samp = np.linspace(1, 5, 50)
_noise = np.random.normal(size=len(x_samp), scale=0.06)
y_samp = 2.5 * np.exp(1.2 * x_samp) + 0.7 + _noise
y_samp2 = 2.5 * np.log(1.2 * x_samp) + 0.7 + _noise

Code

Approach 1 - lmfit Model

Fit exponential data

regressor = lmfit.models.ExponentialModel()                # 1    
initial_guess = dict(amplitude=1, decay=-1)                # 2
results = regressor.fit(y_samp, x=x_samp, **initial_guess)
y_fit = results.best_fit    

plt.plot(x_samp, y_samp, "o", label="Data")
plt.plot(x_samp, y_fit, "k--", label="Fit")
plt.legend()

Approach 2 - Custom Model

Fit log data

regressor = lmfit.Model(func_log)                          # 1
initial_guess = dict(a=1, b=.1, c=.1)                      # 2
results = regressor.fit(y_samp2, x=x_samp, **initial_guess)
y_fit = results.best_fit

plt.plot(x_samp, y_samp2, "o", label="Data")
plt.plot(x_samp, y_fit, "k--", label="Fit")
plt.legend()

Details

1. Choose a regression class
2. Supply named, initial guesses that respect the function's domain

You can determine the inferred parameters from the regressor object. Example:

regressor.param_names
# ['decay', 'amplitude']

To make predictions, use the ModelResult.eval() method.

model = results.eval
y_pred = model(x=np.array([1.5]))

Note: the ExponentialModel() follows a decay function, which accepts two parameters, one of which is negative.

See also ExponentialGaussianModel(), which accepts more parameters.

Install the library via > pip install lmfit.

The equation of a line is:

f(x) = A*x + b = y

For a segment, it is exactly the same, except that x is included on an interval I.

If you have two segments, defined as follow:

Segment1 = {(X1, Y1), (X2, Y2)}
Segment2 = {(X3, Y3), (X4, Y4)}

The abcisse Xa of the potential point of intersection (Xa,Ya) must be contained in both interval I1 and I2, defined as follow :

I1 = [min(X1,X2), max(X1,X2)]
I2 = [min(X3,X4), max(X3,X4)]

And we could say that Xa is included into :

Ia = [max( min(X1,X2), min(X3,X4) ),
      min( max(X1,X2), max(X3,X4) )]

Now, we need to check that this interval Ia exists :

if (max(X1,X2) < min(X3,X4)):
    return False  # There is no mutual abcisses

So, we have two line formula, and a mutual interval. Your line formulas are:

f1(x) = A1*x + b1 = y
f2(x) = A2*x + b2 = y

As we got two points by segment, we are able to determine A1, A2, b1 and b2:

A1 = (Y1-Y2)/(X1-X2)  # Pay attention to not dividing by zero
A2 = (Y3-Y4)/(X3-X4)  # Pay attention to not dividing by zero
b1 = Y1-A1*X1 = Y2-A1*X2
b2 = Y3-A2*X3 = Y4-A2*X4

If the segments are parallel, then A1 == A2 :

if (A1 == A2):
    return False  # Parallel segments

A point (Xa,Ya) standing on both line must verify both formulas f1 and f2:

Ya = A1 * Xa + b1
Ya = A2 * Xa + b2
A1 * Xa + b1 = A2 * Xa + b2
Xa = (b2 - b1) / (A1 - A2)   # Once again, pay attention to not dividing by zero

The last thing to do is check that Xa is included into Ia:

if ( (Xa < max( min(X1,X2), min(X3,X4) )) or
     (Xa > min( max(X1,X2), max(X3,X4) )) ):
    return False  # intersection is out of bound
else:
    return True

In addition to this, you may check at startup that two of the four provided points are not equals to avoid all that testing.

append() creates a new array which can be the old array with the appended element.

I think it's more normal to use the proper method for adding an element:

a = numpy.append(a, a[0])

Modern versions of Swift use DispatchQueue.main.async to dispatch to the main thread:

DispatchQueue.main.async { 
  // your code here
}

To dispatch after on the main queue, use:

DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
  // your code here
}

Older versions of Swift used:

dispatch_async(dispatch_get_main_queue(), {
  let delegateObj = UIApplication.sharedApplication().delegate as YourAppDelegateClass
  delegateObj.addUIImage("yourstring")
})

Here you wanna make a pointer to the first element of the array

uint8_t (*matrix_ptr)[20] = l_matrix;

With typedef, this looks cleaner

typedef uint8_t array_of_20_uint8_t[20];
array_of_20_uint8_t *matrix_ptr = l_matrix;

Then you can enjoy life again :)

matrix_ptr[0][1] = ...;

Beware of the pointer/array world in C, much confusion is around this.

Edit

Reviewing some of the other answers here, because the comment fields are too short to do there. Multiple alternatives were proposed, but it wasn't shown how they behave. Here is how they do

uint8_t (*matrix_ptr)[][20] = l_matrix;

If you fix the error and add the address-of operator & like in the following snippet

uint8_t (*matrix_ptr)[][20] = &l_matrix;

Then that one creates a pointer to an incomplete array type of elements of type array of 20 uint8_t. Because the pointer is to an array of arrays, you have to access it with

(*matrix_ptr)[0][1] = ...;

And because it's a pointer to an incomplete array, you cannot do as a shortcut

matrix_ptr[0][0][1] = ...;

Because indexing requires the element type's size to be known (indexing implies an addition of an integer to the pointer, so it won't work with incomplete types). Note that this only works in C, because T[] and T[N] are compatible types. C++ does not have a concept of compatible types, and so it will reject that code, because T[] and T[10] are different types.

The following alternative doesn't work at all, because the element type of the array, when you view it as a one-dimensional array, is not uint8_t, but uint8_t[20]

uint8_t *matrix_ptr = l_matrix; // fail

The following is a good alternative

uint8_t (*matrix_ptr)[10][20] = &l_matrix;

You access it with

(*matrix_ptr)[0][1] = ...;
matrix_ptr[0][0][1] = ...; // also possible now

It has the benefit that it preserves the outer dimension's size. So you can apply sizeof on it

sizeof (*matrix_ptr) == sizeof(uint8_t) * 10 * 20

There is one other answer that makes use of the fact that items in an array are contiguously stored

uint8_t *matrix_ptr = l_matrix[0];

Now, that formally only allows you to access the elements of the first element of the two dimensional array. That is, the following condition hold

matrix_ptr[0] = ...; // valid
matrix_ptr[19] = ...; // valid

matrix_ptr[20] = ...; // undefined behavior
matrix_ptr[10*20-1] = ...; // undefined behavior

You will notice it probably works up to 10*20-1, but if you throw on alias analysis and other aggressive optimizations, some compiler could make an assumption that may break that code. Having said that, i've never encountered a compiler that fails on it (but then again, i've not used that technique in real code), and even the C FAQ has that technique contained (with a warning about its UB'ness), and if you cannot change the array type, this is a last option to save you :)

tl;dr

LocalDate.parse( 
    "19/05/2009" , 
    DateTimeFormatter.ofPattern( "dd/MM/uuuu" ) 
)

Details

The other Answers with java.util.Date, java.sql.Date, and SimpleDateFormat are now outdated.

LocalDate

The modern way to do date-time is work with the java.time classes, specifically LocalDate. The LocalDate class represents a date-only value without time-of-day and without time zone.

DateTimeFormatter

To parse, or generate, a String representing a date-time value, use the DateTimeFormatter class.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu" );
LocalDate ld = LocalDate.parse( "19/05/2009" , f );

Do not conflate a date-time object with a String representing its value. A date-time object has no format, while a String does. A date-time object, such as LocalDate, can generate a String to represent its internal value, but the date-time object and the String are separate distinct objects.

You can specify any custom format to generate a String. Or let java.time do the work of automatically localizing.

DateTimeFormatter f = 
    DateTimeFormatter.ofLocalizedDate( FormatStyle.FULL )
                     .withLocale( Locale.CANADA_FRENCH ) ;
String output = ld.format( f );

Dump to console.

System.out.println( "ld: " + ld + " | output: " + output );

ld: 2009-05-19 | output: mardi 19 mai 2009

See in action in IdeOne.com.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Simple elegant working solution:

img {
  width: 600px;  /*width of parent container*/
  height: 350px; /*height of parent container*/
  object-fit: contain;
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

Check your node version node -v and your npm version npm -v Then To update your npm, type this into your terminal: npm install npm@latest -g

You could write a function that takes a filename and an environment name, checks to see if the file has been loaded into the environment and uses sys.source to source the file if not.

Here's a quick and untested function (improvements welcome!):

include <- function(file, env) {
  # ensure file and env are provided
  if(missing(file) || missing(env))
    stop("'file' and 'env' must be provided")
  # ensure env is character
  if(!is.character(file) || !is.character(env))
    stop("'file' and 'env' must be a character")

  # see if env is attached to the search path
  if(env %in% search()) {
    ENV <- get(env)
    files <- get(".files",ENV)
    # if the file hasn't been loaded
    if(!(file %in% files)) {
      sys.source(file, ENV)                        # load the file
      assign(".files", c(file, files), envir=ENV)  # set the flag
    }
  } else {
    ENV <- attach(NULL, name=env)      # create/attach new environment
    sys.source(file, ENV)              # load the file
    assign(".files", file, envir=ENV)  # set the flag
  }
}

Quick fix:

To remove the gap under the image, you can:

• Set the vertical-align property of the image to vertical-align: bottom; vertical-align: top; or vertical-align: middle;
• Set the display property of the image to display:block;

See the following code for a live demo:

#vAlign img {_x000D_
  vertical-align :bottom;_x000D_
}_x000D_
#block img{_x000D_
  display:block;_x000D_
}_x000D_
_x000D_
div {border: 1px solid red;width:100px;}_x000D_
img {width:100px;}

<p>No fix:</p>_x000D_
<div><img src="http://i.imgur.com/RECDV24.jpg" /></div>_x000D_
_x000D_
<p>With vertical-align:bottom; on image:</p>_x000D_
<div id="vAlign"><img src="http://i.imgur.com/RECDV24.jpg" /></div>_x000D_
_x000D_
<p>With display:block; on image:</p>_x000D_
<div id="block"><img src="http://i.imgur.com/RECDV24.jpg" /></div>

Explanation: why is there a gap under the image?

The gap or extra space under the image isn't a bug or issue, it is the default behaviour. The root cause is that images are replaced elements (see MDN replaced elements). This allows them to "act like image" and have their own intrinsic dimensions, aspect ratio....
Browsers compute their display property to inline but they give them a special behaviour which makes them closer to inline-block elements (as you can vertical align them, give them a height, top/bottom margin and padding, transforms ...).

This also means that:

<img> has no baseline, so when images are used in an inline formatting context with vertical-align: baseline, the bottom of the image will be placed on the text baseline.
(source: MDN, emphasis mine)

As browsers by default compute the vertical-align property to baseline, this is the default behaviour. The following image shows where the baseline is located on text:

(Image source)

Baseline aligned elements need to keep space for the descenders that extend below the baseline (like j, p, g ...) as you can see in the above image. In this configuration, the bottom of the image is aligned on the baseline as you can see in this example:

div{border:1px solid red;font-size:30px;}_x000D_
img{width:100px;height:auto;}

<div>_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />jpq are letters with descender_x000D_
</div>

This is why the default behaviour of the <img> tag creates a gap at the bottom of it's container and why changing the vertical-align property or the display property removes it as in the following demo:

div {width: 100px;border: 1px solid red;}_x000D_
img {width: 100px;height: auto;}_x000D_
_x000D_
.block img{_x000D_
  display:block;_x000D_
}_x000D_
.bottom img{_x000D_
  vertical-align:bottom;_x000D_
}

<p>Default:</p>_x000D_
<div>_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />_x000D_
</div>_x000D_
<p>With display:block;</p>_x000D_
<div class="block">_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />_x000D_
</div>_x000D_
<p>With vertical-align:bottom;</p>_x000D_
<div class="bottom">_x000D_
  <img src="http://i.imgur.com/RECDV24.jpg" />_x000D_
</div>

if you are using cp doesn't save existing files when copying folders of the same name. Lets say you have this folders:

/myFolder
  someTextFile.txt

/someOtherFolder
  /myFolder
    wellHelloThere.txt

Then you copy one over the other:

cp /someOtherFolder/myFolder /myFolder

result:

/myFolder
  wellHelloThere.txt

This is at least what happens on macOS and I wanted to preserve the diff files so I used rsync.

The above solution for the JsonCreationConverter<T> is all over the internet, but has a flaw that manifests itself in rare occasions. The new JsonReader created in the ReadJson method does not inherit any of the original reader's configuration values (Culture, DateParseHandling, DateTimeZoneHandling, FloatParseHandling, etc...). These values should be copied over before using the new JsonReader in serializer.Populate().

This is the best I could come up with to fix some of the problems with the above implementation, but I still think there are some things being overlooked:

Update I updated this to have a more explicit method that makes a copy of an existing reader. This just encapsulates the process of copying over individual JsonReader settings. Ideally this function would be maintained in the Newtonsoft library itself, but for now, you can use the following:

/// <summary>Creates a new reader for the specified jObject by copying the settings
/// from an existing reader.</summary>
/// <param name="reader">The reader whose settings should be copied.</param>
/// <param name="jToken">The jToken to create a new reader for.</param>
/// <returns>The new disposable reader.</returns>
public static JsonReader CopyReaderForObject(JsonReader reader, JToken jToken)
{
    JsonReader jTokenReader = jToken.CreateReader();
    jTokenReader.Culture = reader.Culture;
    jTokenReader.DateFormatString = reader.DateFormatString;
    jTokenReader.DateParseHandling = reader.DateParseHandling;
    jTokenReader.DateTimeZoneHandling = reader.DateTimeZoneHandling;
    jTokenReader.FloatParseHandling = reader.FloatParseHandling;
    jTokenReader.MaxDepth = reader.MaxDepth;
    jTokenReader.SupportMultipleContent = reader.SupportMultipleContent;
    return jTokenReader;
}

This should be used as follows:

public override object ReadJson(JsonReader reader,
                                Type objectType,
                                object existingValue,
                                JsonSerializer serializer)
{
    if (reader.TokenType == JsonToken.Null)
        return null;
    // Load JObject from stream
    JObject jObject = JObject.Load(reader);
    // Create target object based on JObject
    T target = Create(objectType, jObject);
    // Populate the object properties
    using (JsonReader jObjectReader = CopyReaderForObject(reader, jObject))
    {
        serializer.Populate(jObjectReader, target);
    }
    return target;
}

Older solution follows:

/// <summary>Base Generic JSON Converter that can help quickly define converters for specific types by automatically
/// generating the CanConvert, ReadJson, and WriteJson methods, requiring the implementer only to define a strongly typed Create method.</summary>
public abstract class JsonCreationConverter<T> : JsonConverter
{
    /// <summary>Create an instance of objectType, based properties in the JSON object</summary>
    /// <param name="objectType">type of object expected</param>
    /// <param name="jObject">contents of JSON object that will be deserialized</param>
    protected abstract T Create(Type objectType, JObject jObject);

    /// <summary>Determines if this converted is designed to deserialization to objects of the specified type.</summary>
    /// <param name="objectType">The target type for deserialization.</param>
    /// <returns>True if the type is supported.</returns>
    public override bool CanConvert(Type objectType)
    {
        // FrameWork 4.5
        // return typeof(T).GetTypeInfo().IsAssignableFrom(objectType.GetTypeInfo());
        // Otherwise
        return typeof(T).IsAssignableFrom(objectType);
    }

    /// <summary>Parses the json to the specified type.</summary>
    /// <param name="reader">Newtonsoft.Json.JsonReader</param>
    /// <param name="objectType">Target type.</param>
    /// <param name="existingValue">Ignored</param>
    /// <param name="serializer">Newtonsoft.Json.JsonSerializer to use.</param>
    /// <returns>Deserialized Object</returns>
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        if (reader.TokenType == JsonToken.Null)
            return null;

        // Load JObject from stream
        JObject jObject = JObject.Load(reader);

        // Create target object based on JObject
        T target = Create(objectType, jObject);

        //Create a new reader for this jObject, and set all properties to match the original reader.
        JsonReader jObjectReader = jObject.CreateReader();
        jObjectReader.Culture = reader.Culture;
        jObjectReader.DateParseHandling = reader.DateParseHandling;
        jObjectReader.DateTimeZoneHandling = reader.DateTimeZoneHandling;
        jObjectReader.FloatParseHandling = reader.FloatParseHandling;

        // Populate the object properties
        serializer.Populate(jObjectReader, target);

        return target;
    }

    /// <summary>Serializes to the specified type</summary>
    /// <param name="writer">Newtonsoft.Json.JsonWriter</param>
    /// <param name="value">Object to serialize.</param>
    /// <param name="serializer">Newtonsoft.Json.JsonSerializer to use.</param>
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        serializer.Serialize(writer, value);
    }
}

1) If a DataFrame has got Nan and Non Null values and you want to find whether the DataFrame
is empty or not then try this code.
2) when this situation can happen? 
This situation happens when a single function is used to plot more than one DataFrame 
which are passed as parameter.In such a situation the function try to plot the data even 
when a DataFrame is empty and thus plot an empty figure!.
It will make sense if simply display 'DataFrame has no data' message.
3) why? 
if a DataFrame is empty(i.e. contain no data at all.Mind you DataFrame with Nan values 
is considered non empty) then it is desirable not to plot but put out a message :
Suppose we have two DataFrames df1 and df2.
The function myfunc takes any DataFrame(df1 and df2 in this case) and print a message 
if a DataFrame is empty(instead of plotting):

df1                     df2
col1 col2           col1 col2 
Nan   2              Nan  Nan 
2     Nan            Nan  Nan  

and the function:

def myfunc(df):
  if (df.count().sum())>0: ##count the total number of non Nan values.Equal to 0 if DataFrame is empty
     print('not empty')
     df.plot(kind='barh')
  else:
     display a message instead of plotting if it is empty
     print('empty')

I can't speak for the 2nd or 3rd, but if you install Node first, Sublime-HTMLPrettify works pretty well. You have to setup your own key shortcut once it is installed. One thing I noticed on Windows, you may need to edit your path for Node in the %PATH% variable if it is already long (I think the limit is 1024 for the %PATH% variable, and anything after that is ignored.)

There is a Windows bug, but in the issues there is a fix for it. You'll need to edit the HTMLPrettify.py file - https://github.com/victorporof/Sublime-HTMLPrettify/issues/12

use the JSON function >

JSON.parse(theString)

sed is the stream editor, in that you can use | (pipe) to send standard streams (STDIN and STDOUT specifically) through sed and alter them programmatically on the fly, making it a handy tool in the Unix philosophy tradition; but can edit files directly, too, using the -i parameter mentioned below.
Consider the following:

sed -i -e 's/few/asd/g' hello.txt

s/ is used to substitute the found expression few with asd:

The few, the brave.

---

The asd, the brave.

/g stands for "global", meaning to do this for the whole line. If you leave off the /g (with s/few/asd/, there always needs to be three slashes no matter what) and few appears twice on the same line, only the first few is changed to asd:

The few men, the few women, the brave.

---

The asd men, the few women, the brave.

This is useful in some circumstances, like altering special characters at the beginnings of lines (for instance, replacing the greater-than symbols some people use to quote previous material in email threads with a horizontal tab while leaving a quoted algebraic inequality later in the line untouched), but in your example where you specify that anywhere few occurs it should be replaced, make sure you have that /g.

The following two options (flags) are combined into one, -ie:

-i option is used to edit in place on the file hello.txt.

-e option indicates the expression/command to run, in this case s/.

Note: It's important that you use -i -e to search/replace. If you do -ie, you create a backup of every file with the letter 'e' appended.

You can add days to a date like this:

// add days to current **DateTime**
var addedDateTime = DateTime.Now.AddDays(10);

// add days to current **Date**
var addedDate = DateTime.Now.Date.AddDays(10);

// add days to any DateTime variable
var addedDateTime = anyDate.AddDay(10);

Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.

Create /etc/nginx/sites-available and /etc/nginx/sites-enabled and then edit the http block inside /etc/nginx/nginx.conf and add this line

include /etc/nginx/sites-enabled/*;

Of course, all the files will be inside sites-available, and you'd create a symlink for them inside sites-enabled for those you want enabled.

This should work:

String s = "123foo";
Character.isDigit(s.charAt(0));

This error comes because compile does not know where to find the class..so it occurs mainly when u copy or import item ..to solve this .. 1.change the namespace in the formname.cs and formname.designer.cs to the name of your project .

I wrote the following to fix the nuisance non-ascii quotes and force conversion to something usable.

unicodeToAsciiMap = {u'\u2019':"'", u'\u2018':"`", }

def unicodeToAscii(inStr):
    try:
        return str(inStr)
    except:
        pass
    outStr = ""
    for i in inStr:
        try:
            outStr = outStr + str(i)
        except:
            if unicodeToAsciiMap.has_key(i):
                outStr = outStr + unicodeToAsciiMap[i]
            else:
                try:
                    print "unicodeToAscii: add to map:", i, repr(i), "(encoded as _)"
                except:
                    print "unicodeToAscii: unknown code (encoded as _)", repr(i)
                outStr = outStr + "_"
    return outStr

It can also happen when drawing a new (other) table. I solved this by first removing the previous table:

$("#prod_tabel_ph").remove();

This error can be caused by missing the following dll

To have this dll install: https://www.microsoft.com/en-us/software-download/mediafeaturepack as already explained above

check two things

pip2 --version   

and

pip3 --version

because the default pip may be anyone of this so it is always better to check both.

easily set

I'll be lucky if anybody ever reads this... but in order to not return a list of type object in my Clone methods, I created an interface:

public interface IMyCloneable<T>
{
    T Clone();
}

Then I specified the extension:

public static List<T> Clone<T>(this List<T> listToClone) where T : IMyCloneable<T>
{
    return listToClone.Select(item => (T)item.Clone()).ToList();
}

And here is an implementation of the interface in my A/V marking software. I wanted to have my Clone() method return a list of VidMark (while the ICloneable interface wanted my method to return a list of object):

public class VidMark : IMyCloneable<VidMark>
{
    public long Beg { get; set; }
    public long End { get; set; }
    public string Desc { get; set; }
    public int Rank { get; set; } = 0;

    public VidMark Clone()
    {
        return (VidMark)this.MemberwiseClone();
    }
}

And finally, the usage of the extension inside a class:

private List<VidMark> _VidMarks;
private List<VidMark> _UndoVidMarks;

//Other methods instantiate and fill the lists

private void SetUndoVidMarks()
{
    _UndoVidMarks = _VidMarks.Clone();
}

Anybody like it? Any improvements?

$_SERVER['REQUEST_URI'] should work.

1. The point of using CDN is that it is faster, first of all, because it is a distributed network, but secondly, because the static files are being cached by the browsers and chances are high that, for example, the CDN's jquery library that your site uses had already been downloaded by the user's browser, and therefore the file had been cached, and therefore no unnecessary download is taking place. That being said, it is still a good idea to provide a fallback.

   Now, the point of bootstrap's npm package

   is that it provides bootstrap's javascript file as a module. As has been mentioned above, this makes it possible to require it using browserify, which is the most likely use case and, as I understand it, the main reason for bootstrap being published on npm.

2. How to use it

   Imagine the following project structure:

   project
   |-- node_modules
   |-- public
   |   |-- css
   |   |-- img
   |   |-- js
   |   |-- index.html
   |-- package.json
   
   

In your index.html you can reference both css and js files like this:

<link rel="stylesheet" href="../node_modules/bootstrap/dist/css/bootstrap.min.css">
<script src="../node_modules/bootstrap/dist/js/bootstrap.min.js"></script>

Which is the simplest way, and correct for the .css files. But it is much better to include the bootstrap.js file like this somewhere in your public/js/*.js files:

var bootstrap = require('bootstrap');

And you include this code only in those javascript files where you actually need bootstrap.js. Browserify takes care of including this file for you.

Now, the drawback is that you now have your front-end files as node_modules dependencies, and the node_modules folder is usually not checked in with git. I think this is the most controversial part, with many opinions and solutions.

UPDATE March 2017

Almost two years have passed since I wrote this answer and an update is in place.

Now the generally accepted way is to use a bundler like webpack (or another bundler of choice) to bundle all your assets in a build step.

Firstly, it allows you to use commonjs syntax just like browserify, so to include bootstrap js code in your project you do the same:

const bootstrap = require('bootstrap');

As for the css files, webpack has so called "loaders". They allow you write this in your js code:

require('bootstrap/dist/css/bootstrap.css');

and the css files will be "magically" included in your build. They will be dynamically added as <style /> tags when your app runs, but you can configure webpack to export them as a separate css file. You can read more about that in webpack's documentation.

In conclusion.

1. You should "bundle" your app code with a bundler
2. You shouldn't commit neither node_modules nor the dynamically built files to git. You can add a build script to npm which should be used to deploy files on server. Anyway, this can be done in different ways depending on your preferred build process.

There are many ways of running separate threads in .Net, each has different behaviors. Do you need to continue running the thread after the GUI quits? Do you need to pass information between the thread and GUI? Does the thread need to update the GUI? Should the thread do one task then quit, or should it continue running? The answers to these questions will tell you which method to use.

There is a good async method article at the Code Project web site that describes the various methods and provides sample code.

Note this article was written before the async/await pattern and Task Parallel Library were introduced into .NET.

std::move itself does nothing rather than a static_cast. According to cppreference.com

It is exactly equivalent to a static_cast to an rvalue reference type.

Thus, it depends on the type of the variable you assign to after the move, if the type has constructors or assign operators that takes a rvalue parameter, it may or may not steal the content of the original variable, so, it may leave the original variable to be in an unspecified state:

Unless otherwise specified, all standard library objects that have been moved from being placed in a valid but unspecified state.

Because there is no special move constructor or move assign operator for built-in literal types such as integers and raw pointers, so, it will be just a simple copy for these types.

Assuming such a query would return a single row, you could use either

select @EmpId = Id from dbo.Employee

Or

set @EmpId = (select Id from dbo.Employee)

You forgot to define the default value for left so it doesn't know how to animate.

.test {
    left: 0;
    transition:left 1s linear;
}

See here: http://jsfiddle.net/shomz/yFy5n/5/

You could use the maven enforcer plugin with the banned dependency rule. This would allow you to ban all the aliases that you don't want and allow only the one you do want. These rules will fail the maven build of your project when violated. Furthermore, if this rule applies to all projects in an enterprise you could put the plugin configuration in a corporate parent pom.

see:

• http://maven.apache.org/plugins/maven-enforcer-plugin/
• http://maven.apache.org/enforcer/enforcer-rules/bannedDependencies.html

You are supposed to download the jar files that contain these libraries. Libraries may be used by adding them to the classpath.

For Commons Net you need to download the binary files from Commons Net download page. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. to /lib.

If you're running your application from the command-line you'll have to define the classpath in the java command: java -cp .;lib/commons-net-2-2.jar myapp. More info about how to set the classpath can be found from Oracle documentation. You must specify all directories and jar files you'll need in the classpath excluding those implicitely provided by the Java runtime. Notice that there is '.' in the classpath, it is used to include the current directory in case your compiled class is located in the current directory.

For more advanced reading, you might want to read about how to define the classpath for your own jar files, or the directory structure of a war file when you're creating a web application.

If you are using an IDE, such as Eclipse, you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library.

In my case, I was going nuts since there wasn't any issues with the string to be decoded, since I could successfully decode it on online tools. Until I found out that you first have to decodeURIComponent what you are decoding, like so:

atob(decodeURIComponent(dataToBeDecoded));

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

int i;
for (i = 0; i < ARRAY_SIZE; ++i)
{
  myArray[i] = VALUE;
}

I think this is better than

int myArray[10] = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5...

incase the size of the array changes.

Depending on the encoding you wish to use:

var str = System.Text.Encoding.Default.GetString(result);

It is time inefficient to compare each number, needlessly leading to a linear complexity. Having said that, this approach avoids any inequality checks:

import itertools

m, n = 5, 10
for i in itertools.chain(range(m), range(m + 1, n)):
    print(i)  # skips m = 5

As an aside, you woudn't want to use (*range(m), *range(m + 1, n)) even though it works because it will expand the iterables into a tuple and this is memory inefficient.

Using Backtick

Backticks are commonly used for multi-line strings or when you want to interpolate an expression within your string

let title = 'John';_x000D_
let address = 'address';_x000D_
let address2 = 'address2222';_x000D_
let address3 = 'address33333';_x000D_
let address4 = 'address44444';_x000D_
document.getElementById("address_box").innerText = `${title} _x000D_
${address}_x000D_
${address2}_x000D_
${address3} _x000D_
${address4}`;

<div id="address_box">_x000D_
</div>

The very first alias I made once I started customizing my profile in PowerShell was 'which'.

New-Alias which get-command

To add this to your profile, type this:

"`nNew-Alias which get-command" | add-content $profile

The `n at the start of the last line is to ensure it will start as a new line.

You can add category lines to log4j.xml:

<category name="org.hibernate.type">
    <priority value="TRACE"/>
</category>

and add hibernate properties:

<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="use_sql_comments">true</property>

I just found this out by trying to see if my event was attached....

if you do :

item.onclick

it will return "null"

but if you do:

item.hasOwnProperty('onclick')

then it is "TRUE"

so I think that when you use "addEventListener" to add event handlers, the only way to access it is through "hasOwnProperty". I wish I knew why or how but alas, after researching, I haven't found an explanation.

To my knowledge, there is a well diffused algorithm allowing to output to the necessary number of significant digits such that when scanning the string back in, the original floating point value is acquired in dtoa.c written by Daniel Gay, which is available here on Netlib (see also the associated paper). This code is used e.g. in Python, MySQL, Scilab, and many others.

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

If you are certain you want to wait and never get interrupted then use sleep in POSIX or Sleep in Windows. In POSIX sleep takes time in seconds so if you want the time to be shorter there are varieties like usleep() which uses microseconds. Sleep in Windows takes milliseconds, it is rare you need finer granularity than that.

It may be that you wish to wait a period of time but want to allow interrupts, maybe in the case of an emergency. sleep can be interrupted by signals but there is a better way of doing it in this case.

Therefore I actually found in practice what you do is wait for an event or a condition variable with a timeout.

In Windows your call is WaitForSingleObject. In POSIX it is pthread_cond_timedwait.

In Windows you can also use WaitForSingleObjectEx and then you can actually "interrupt" your thread with any queued task by calling QueueUserAPC. WaitForSingleObject(Ex) will return a code determining why it exited, so you will know when it returns a "TIMEDOUT" status that it did indeed timeout. You set the Event it is waiting for when you want it to terminate.

With pthread_cond_timedwait you can signal broadcast the condition variable. (If several threads are waiting on the same one, you will need to broadcast to wake them all up). Each time it loops it should check the condition. Your thread can get the current time and see if it has passed or it can look to see if some condition has been met to determine what to do. If you have some kind of queue you can check it. (Your thread will automatically have a mutex locked that it used to wait on the condition variable, so when it checks the condition it has sole access to it).

I'd use a 'where not exists' -- exactly as you suggest in your title:

SELECT `voter`.`ID`, `voter`.`Last_Name`, `voter`.`First_Name`,
       `voter`.`Middle_Name`, `voter`.`Age`, `voter`.`Sex`,
       `voter`.`Party`, `voter`.`Demo`, `voter`.`PV`,
       `household`.`Address`, `household`.`City`, `household`.`Zip`
FROM (`voter`)
JOIN `household` ON `voter`.`House_ID`=`household`.`id`
WHERE `CT` = '5'
AND `Precnum` = 'CTY3'
AND  `Last_Name`  LIKE '%Cumbee%'
AND  `First_Name`  LIKE '%John%'

AND NOT EXISTS (
  SELECT * FROM `elimination`
   WHERE `elimination`.`voter_id` = `voter`.`ID`
)

ORDER BY `Last_Name` ASC
LIMIT 30

That may be marginally faster than doing a left join (of course, depending on your indexes, cardinality of your tables, etc), and is almost certainly much faster than using IN.

To take a screenshot of your app:

1. Start your app as described in Run your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. Click Screen Capture on the left side of the Android DDMS tool window.
4. Optional: To add a device frame around your screenshot, enable the Frame screenshot option.
5. Click Save.

Like AlienWebguy said, per the docs, require.js can blow up if

• You have an anonymous define ("modules that call define() with no string ID") in its own script tag (I assume actually they mean anywhere in global scope)
• You have modules that have conflicting names
• You use loader plugins or anonymous modules but don't use require.js's optimizer to bundle them

I had this problem while including bundles built with browserify alongside require.js modules. The solution was to either:

A. load the non-require.js standalone bundles in script tags before require.js is loaded, or

B. load them using require.js (instead of a script tag)

OK, there was a small typo in my key. Apparently when pasting to file the first letter was cut off and it started with sh-rsa instead of ssh-rsa.

nrathathaus - your answer was very helpful, thanks a lot, this answer is credited to you :) I did like you said and set this in sshd_conf:

LogLevel DEBUG3

By looking at the logs I realized that sshd reads the key correctly but rejects it because of the incorrect identifier.

You can create bitmap with captured image as below:

Bitmap bitmap = Bitmap.createScaledBitmap(capturedImage, width, height, true);

Here you can specify width and height of the bitmap that you want to set to your ImageView. The height and width you can set according to the screen dpi of the device also, by reading the screen dpi of different devices programmatically.

You can find answer in depth here.

But in general with float you need to be aware and take care of the surrounding elements and inline-block simple way to line elements.

Thanks

I think your first line would actually work but I think you need four quotation marks for a string containing a single one (in VB at least):

s = s.Replace("""", "")

for C# you'd have to escape the quotation mark using a backslash:

s = s.Replace("\"", "");

You can use output parameters with sp_executesql.

DECLARE @dbName nvarchar(128) = 'myDb'
DECLARE @siteId int 
DECLARE @SQL nvarchar(max) = N'SELECT TOP 1 @siteId = Id FROM ' + quotename(@dbName) + N'..myTbl'
exec sp_executesql @SQL, N'@siteId int out', @siteId out
select @siteId

You seems to be missing implementation for interface UserDao. If you look at the exception closely it says

No qualifying bean of type [edu.java.spring.ws.dao.UserDao] found for dependency:

The way @Autowired works is that it would automatically look for implementation of a dependency you inject via an interface. In this case since there is no valid implementation of interface UserDao you get the error.Ensure you have a valid implementation for this class and your error should go.

Hope that helps.

Apparently some POST requests looks like a "GET" to the server (like Heroku...)

So I use this strategy and it works for me:

@RequestMapping(value = "/salvar", method = { RequestMethod.GET, RequestMethod.POST })

I had this problem, and the cause was rather silly. I was trying out Microsoft's demo regarding running a ServiceHost from w/in a Command Line executable. I followed the instructions, including where it says to add the appropriate Service (and interface). But I got the above error.

Turns out when I added the service class, VS automatically added the configuration to the app.config. And the demo was trying to add that info too. Since it was already in the config, I removed the demo part, and it worked.

Important things for Java benchmarks are:

• Warm up the JIT first by running the code several times before timing it
• Make sure you run it for long enough to be able to measure the results in seconds or (better) tens of seconds
• While you can't call System.gc() between iterations, it's a good idea to run it between tests, so that each test will hopefully get a "clean" memory space to work with. (Yes, gc() is more of a hint than a guarantee, but it's very likely that it really will garbage collect in my experience.)
• I like to display iterations and time, and a score of time/iteration which can be scaled such that the "best" algorithm gets a score of 1.0 and others are scored in a relative fashion. This means you can run all algorithms for a longish time, varying both number of iterations and time, but still getting comparable results.

I'm just in the process of blogging about the design of a benchmarking framework in .NET. I've got a couple of earlier posts which may be able to give you some ideas - not everything will be appropriate, of course, but some of it may be.

Swift 5+

In my case, I need to update the status bar hidden based on some conditions.

Because of this, I create a base controlller BaseViewController which contains new property hideStatusBar.

Other view controllers are sub-class of this base controller. Finally when I want to update the status bar behavior, I only need to change this hideStatusBar value.

class BaseViewController: UIViewController {

    var hideStatusBar: Bool = false {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
           return hideStatusBar
    }
}

How to use

final class ViewController: BaseViewController, UIScrollViewDelegate {
    let scrollView = UIScrollView()

    ...

    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        UIView.animate(withDuration: 0.3) {
            if scrollView.contentOffset.y > 100 {
                self.hideStatusBar = true
            } else {
                self.hideStatusBar = false
            }
        }
    }
}

Demo

Here is a demo, I'm using UIView.animate(...) to make the transition smoother.

See the exec maven plugin. You can run Java classes using:

mvn exec:java -Dexec.mainClass="com.example.Main" [-Dexec.args="argument1"] ...

The invocation can be as simple as mvn exec:java if the plugin configuration is in your pom.xml. The plugin site on Mojohaus has a more detailed example.

Just thinking you might be feel unfamiliar of the sequence From->Where->Select, as in sql script, it is like Select->From->Where.

But you may not know that inside Sql Engine, it is also parse in the sequence of 'From->Where->Select', To validate it, you can try a simple script

select id as i from table where i=3

and it will not work, the reason is engine will parse Where before Select, so it won't know alias i in the where. To make this work, you can try

select * from (select id as i from table) as t where i = 3

model.find({Branch:branch},function (err, docs){
  if (err) res.send(err)

  res.send(JSON.parse(JSON.stringify(docs)))
});

As the 64bit version is an x86 architecture and was accordingly first called x86-64, that would be the most appropriate name, IMO. Also, x32 is a thing (as mentioned before)—‘x64’, however, is not a continuation of that, so is (theoretically) missleading (even though many people will know what you are talking about) and should thus only be recognised as a marketing thing, not an ‘official’ architecture (again, IMO–obviously, others disagree).

To support SDK version >= 26, you also should build NotificationChanel and set a vibration pattern and sound there. There is a Kotlin code sample:

    val vibrationPattern = longArrayOf(500)
    val soundUri = "<your sound uri>"

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            val notificationManager =    
                 getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
            val attr = AudioAttributes.Builder()
                        .setUsage(AudioAttributes.USAGE_ALARM)
                        .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                        .build()
            val channelName: CharSequence = Constants.NOTIFICATION_CHANNEL_NAME
            val importance = NotificationManager.IMPORTANCE_HIGH
            val notificationChannel =
                NotificationChannel(Constants.NOTIFICATION_CHANNEL_ID, channelName, importance)
                notificationChannel.enableLights(true)
                notificationChannel.lightColor = Color.RED
                notificationChannel.enableVibration(true)
                notificationChannel.setSound(soundUri, attr)
                notificationChannel.vibrationPattern = vibrationPattern
                notificationManager.createNotificationChannel(notificationChannel)
    }

And this is the builder:

 with(NotificationCompat.Builder(applicationContext, Constants.NOTIFICATION_CHANNEL_ID)) {
        setContentTitle("Some title")
        setContentText("Some content")
        setSmallIcon(R.drawable.ic_logo)
        setAutoCancel(true)    
        setVibrate(vibrationPattern)
        setSound(soundUri)
        setDefaults(Notification.DEFAULT_VIBRATE)
        setContentIntent(
            // this is an extension function of context you should build
            // your own pending intent and place it here
            createNotificationPendingIntent(
                Intent(applicationContext, target).apply {
                    flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
                }
            )
        )

        return build()
    }

Be sure your AudioAttributes are chosen right to read more here.

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

Create a dummy tag that is not going to rendered on the page but it will work as holder for ng-repeat:

<dummyTag ng-repeat="featureItem in item.features">{{featureItem.feature}}</br> </dummyTag>

you can use this function to download file from base64.

function downloadPDF(pdf) {
const linkSource = `data:application/pdf;base64,${pdf}`;
const downloadLink = document.createElement("a");
const fileName = "abc.pdf";
downloadLink.href = linkSource;
downloadLink.download = fileName;
downloadLink.click();}

This code will made an anchor tag with href and download file. if you want to use button then you can call click method on your button click.

i hope this will help of you thanks

I know this post is a year old, but I'd like to provide a different solution approach to those who have a similar issue:

1. The jQuery change event is used only on user input fields because if anything else is manipulated (e.g., a div), that manipulation is coming from code. So, find where the manipulation occurs, and then add whatever you need to there.

2. But if that's not possible for any reason (you're using a complicated plugin or can't find any "callback" possibilities) then the jQuery approach I'd suggest is:

   a. For simple DOM manipulation, use jQuery chaining and traversing, $("#content").html('something').end().find(whatever)....

   b. If you'd like to do something else, employ jQuery's bind with custom event and triggerHandler

   $("#content").html('something').triggerHandler('customAction');
   
   $('#content').unbind().bind('customAction', function(event, data) {
      //Custom-action
   });
   

Here's a link to jQuery trigger handler: http://api.jquery.com/triggerHandler/

First of all, beware of that method:

As Jesse Ezel says:

Brad Abrams

"The method might seem convenient, but most of the time I have found that this situation arises from trying to cover up deeper bugs.

Your code should stick to a particular protocol on the use of strings, and you should understand the use of the protocol in library code and in the code you are working with.

The NullOrEmpty protocol is typically a quick fix (so the real problem is still somewhere else, and you got two protocols in use) or it is a lack of expertise in a particular protocol when implementing new code (and again, you should really know what your return values are)."

And if you patch String class... be sure NilClass has not been patch either!

class NilClass
    def empty?; true; end
end

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

If you truly wish to use PHP, you could use

include "file.php";

or

require "file.php";

and then in file.php, use a heredoc & echo it in.

file.php contents:
$some_js_code <<<_code
function myFunction()
{
   Alert("Some JS code would go here.");
}
_code;

At the top of your PHP file, bring in the file using either include or require then in head (or body section) echo it in

<?php
require "file.php";
?>
<html>
<head>
<?php
echo $some_js_code;
?>
</script>
</head>
<body>
</body>
</html>

Different way but it works. Just my $.02...

This shall also work.

The Jayrock RPC library is a great tool for doing this in a nice familliar way for C# developers. It allows you to create a .NET class with the methods you require, and add this class as a script (in a roundabout way) to your page. You can then create a js object of your type and call methods as you would any other object.

It essentially hides away ajax implementation and presents RPC in a familliar format. Mind you the best option really is to use ASP.NET MVC and use jQuery ajax calls to action methods - much more concise and less messing about!

This method handles spaces well.

files="$(find -L "$dir" -type f)"
echo "Count: $(echo -n "$files" | wc -l)"
echo "$files" | while read file; do
  echo "$file"
done

Edit, fixes off-by-one

function count() {
    files="$(find -L "$1" -type f)";
    if [[ "$files" == "" ]]; then
        echo "No files";
        return 0;
    fi
    file_count=$(echo "$files" | wc -l)
    echo "Count: $file_count"
    echo "$files" | while read file; do
        echo "$file"
    done
}

Well, longs can't hold anything but integers.

One option is to use a float: float('234.89')

The other option is to truncate or round. Converting from a float to a long will truncate for you: long(float('234.89'))

>>> long(float('1.1'))
1L
>>> long(float('1.9'))
1L
>>> long(round(float('1.1')))
1L
>>> long(round(float('1.9')))
2L

Use This code ..to change action bar background color. open "res/values/themes.xml" (if not present, create it) and add

<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme"
       parent="@android:style/Theme.Holo.Light.DarkActionBar">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
 <!-- ActionBar styles -->
<style name="MyActionBar"
       parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
    <item name="android:background">@drawable/actionbar_background</item>
</style>

Note : this code works for android 3.0 and higher versions only

I'm not sure why the way you did it doesn't work, but I usually do it with the spyOn function. Something like this:

describe('Testing remote call returning promise', function() {
  var myService;

  beforeEach(module('app.myService'));

  beforeEach(inject( function(_myService_, myOtherService, $q){
    myService = _myService_;
    spyOn(myOtherService, "makeRemoteCallReturningPromise").and.callFake(function() {
        var deferred = $q.defer();
        deferred.resolve('Remote call result');
        return deferred.promise;
    });
  }

  it('can do remote call', inject(function() {
    myService.makeRemoteCall()
      .then(function() {
        console.log('Success');
      });    
  }));

Also remember that you will need to make a $digest call for the then function to be called. See the Testing section of the $q documentation.

------EDIT------

After looking closer at what you're doing, I think I see the problem in your code. In the beforeEach, you're setting myOtherServiceMock to a whole new object. The $provide will never see this reference. You just need to update the existing reference:

beforeEach(inject( function(_myService_, $q){
    myService = _myService_;
    myOtherServiceMock.makeRemoteCallReturningPromise = function() {
        var deferred = $q.defer();
        deferred.resolve('Remote call result');
        return deferred.promise;   
    };
  }

Pure Vanilla CSS / HTML solution in 2021. It uses the CSS appearance: none; property.

Seems to be compatible with all major browsers at this time:

https://caniuse.com/?search=appearance%3A%20none

input[type="radio"]{
   appearance: none;
   border: 1px solid #d3d3d3;
   width: 30px;
   height: 30px;
   content: none;
   outline: none;
   margin: 0;
   box-shadow: rgba(0, 0, 0, 0.24) 0px 3px 8px;
}

input[type="radio"]:checked {
  appearance: none;
  outline: none;
  padding: 0;
  content: none;
  border: none;
}

input[type="radio"]:checked::before{

You say you're using:

time.asctime(time.localtime(date_in_seconds_from_bash))

where date_in_seconds_from_bash is presumably the output of date +%s.

The time.localtime function, as the name implies, gives you local time.

If you want UTC, use time.gmtime() rather than time.localtime().

As JamesNoonan33's answer says, the output of date +%s is timezone invariant, so date +%s is exactly equivalent to date -u %s. It prints the number of seconds since the "epoch", which is 1970-01-01 00:00:00 UTC. The output you show in your question is entirely consistent with that:

date -u
Thu Jul 3 07:28:20 UTC 2014

date +%s
1404372514   # 14 seconds after "date -u" command

date -u +%s
1404372515   # 15 seconds after "date -u" command

What about sending a HEAD request instead of a normal GET request. The following snipped (copied from a similar question) does exactly that.

>>> import httplib
>>> conn = httplib.HTTPConnection("www.google.com")
>>> conn.request("HEAD", "/index.html")
>>> res = conn.getresponse()
>>> print res.status, res.reason
200 OK
>>> print res.getheaders()
[('content-length', '0'), ('expires', '-1'), ('server', 'gws'), ('cache-control', 'private, max-age=0'), ('date', 'Sat, 20 Sep 2008 06:43:36 GMT'), ('content-type', 'text/html; charset=ISO-8859-1')]

A user above says "well, you'll never really need to go above 10 for most designs."

Depending on your project, you may only need z-indexes 0-1, or z-indexes 0-10000. You'll often need to play in the higher digits...especially if you are working with lightbox viewers (9999 seems to be the standard and if you want to top their z-index, you'll need to exceed that!)

To accomplish this using autolayout, try setting a variable width constraint:

You may also need to adjust your Content Hugging Priority and Content Compression Resistance Priority to get the results you need.

UILabel is completely automatically self-sizing:

This UILabel is simply set to be centered on the screen (two constraints only, horizontal/vertical):

It changes widths totally automatically:

You do not need to set any width or height - it's totally automatic.

Notice the small yellow squares are simply attached ("spacing" of zero). They automatically move as the UILabel resizes.

Adding a ">=" constraint sets a minimum width for the UILabel:

I fixed my issue in Kotlin like this:

scrollview.isFocusableInTouchMode = true
scrollview.fullScroll(View.FOCUS_UP)
scrollview.smoothScrollTo(0,0)

You can also create an extension of this like:

ScrollView.moveToTop()
{
    this.isFocusableInTouchMode = true
    this.fullScroll(View.FOCUS_UP)
    this.smoothScrollTo(0,0)
}

and use it like:

scrollView.moveToTop()

This issue came for me due to the fact that .. i was running server with selenium-server-standalone-2.32.0 and client registered with selenium-server-standalone-2.37.0 .. When i made both selenium-server-standalone-2.32.0 and ran then things worked fine

As mentioned in this Jakob Nielsen article, drop down lists should be avoided for data that is well known to the user:

Menus of data well known to users, such as the month and year of their birth. Such information is often hardwired into users' fingers, and having to select such options from a menu breaks the standard paradigm for entering information and can even create more work for users.

The ideal solution is likely something like follows:

• Provide 3 separate text boxes for day, month, and year (labeled appropriately)
• Sort the text boxes according to the user's culture.
• Day and Month text boxes should be sized so that a 2 digit input is assumed.
• Year text box should be sized so that a 4 digit year is assumed.
• Allow the user to enter a 2 or 4 digit year. Assume a 2 digit year is 1900, and update the textbox to reflect this onBlur (or on a following confirmation step).
• Allow the user to enter either a month number OR month name.

EDIT: Here is how we implemented our DOB picker: Masked text input field with HTML5 regex to force the numeric keyboard on iOS devices.

When you change orientations , Android kill that activity and created new activity . I suggest to use retrofit with Rx java . which handle crashes automatically .

Use these method when retrofit call.

.subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread())

Command-line:

powershell gwmi Win32_LogicalDisk -ComputerName remotecomputer -Filter "DriveType=3" ^|
select Name, FileSystem,FreeSpace,BlockSize,Size ^| % {$_.BlockSize=
(($_.FreeSpace)/($_.Size))*100;$_.FreeSpace=($_.FreeSpace/1GB);$_.Size=($_.Size/1GB);$_}
^| Format-Table Name, @{n='FS';e={$_.FileSystem}},@{n='Free, Gb';e={'{0:N2}'-f
$_.FreeSpace}}, @{n='Free,%';e={'{0:N2}'-f $_.BlockSize}},@{n='Capacity ,Gb';e={'{0:N3}'
-f $_.Size}} -AutoSize

Output:

Name FS   Free, Gb Free,% Capacity ,Gb

Here is what worked for me in Windows 7 to disable secure-file-priv (Option #2 from vhu's answer):

1. Stop the MySQL server service by going into services.msc.
2. Go to C:\ProgramData\MySQL\MySQL Server 5.6 (ProgramData was a hidden folder in my case).
3. Open the my.ini file in Notepad.
4. Search for 'secure-file-priv'.
5. Comment the line out by adding '#' at the start of the line. For MySQL Server 5.7.16 and above, commenting won't work. You have to set it to an empty string like this one - secure-file-priv=""
6. Save the file.
7. Start the MySQL server service by going into services.msc.

You can do that using CSS3.

Here is the HTML code snippet:

<ul id="listitem_ascolun">_x000D_

 <li>10</li>_x000D_
 <li>11</li>_x000D_
 <li>12</li>    _x000D_
</ul>

& Here is the CSS3 code snippet :

#listitem_ascolun ul{margin:0;padding:0;list-style:none;}_x000D_
_x000D_
#listitem_ascolun {_x000D_

}

Foreign key and check constraints have the concept of being trusted or untrusted, as well as being enabled and disabled. See the MSDN page for ALTER TABLE for full details.

WITH CHECK is the default for adding new foreign key and check constraints, WITH NOCHECK is the default for re-enabling disabled foreign key and check constraints. It's important to be aware of the difference.

Having said that, any apparently redundant statements generated by utilities are simply there for safety and/or ease of coding. Don't worry about them.

Base @Dan J this version don't care max/min, more like sql :)

public static bool IsBetween(this decimal me, decimal a, decimal b, bool include = true)
{
    var left = Math.Min(a, b);
    var righ = Math.Max(a, b);

    return include
        ? (me >= left && me <= righ)
        : (me > left && me < righ)
    ;
}

This is in addition to @phil mccull's accepted answer.

I use his method but I also automate the process by creating a T4 template to be run pre-build.

Pre-Build Commands:

set textTemplatingPath="%CommonProgramFiles(x86)%\Microsoft Shared\TextTemplating\$(VisualStudioVersion)\texttransform.exe"
if %textTemplatingPath%=="\Microsoft Shared\TextTemplating\$(VisualStudioVersion)\texttransform.exe" set textTemplatingPath="%CommonProgramFiles%\Microsoft Shared\TextTemplating\$(VisualStudioVersion)\texttransform.exe"
%textTemplatingPath% "$(ProjectDir)CacheBuster.tt"

T4 template:

Generated File:

Store in variable before require.config.js is loaded:

Reference in require.config.js:

The requested jar is probably not jackson-annotations-x.y.z.jar but jackson-core-x.y.z.jar which could be found here: http://www.java2s.com/Code/Jar/j/Downloadjacksoncore220rc1jar.htm

In addition to the answer by fenix2222 (which worked for me) I had to modify the last line to:

config.Save(ConfigurationSaveMode.Modified);

Without this, the new value was still being written to the config file but the old value was retrieved when debugging.

Since the question mentions VirtualBox, this one works currently:

VBoxManage convertfromraw imagefile.dd vmdkname.vmdk --format VMDK

Run it without arguments for a few interesting details (notably the --variant flag):

VBoxManage convertfromraw

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

You can also use switch case like

                    String columndata2 = "";
                    if (cell.getColumnIndex() == 1) {// To match column index

                        switch (cell.getCellType()) {
                            case Cell.CELL_TYPE_BLANK:
                                columndata2 = "";
                                break;
                            case Cell.CELL_TYPE_NUMERIC:
                                columndata2 = "" + cell.getNumericCellValue();
                                break;
                            case Cell.CELL_TYPE_STRING:
                                columndata2 = cell.getStringCellValue();
                                break;
                        }

                    }
                    System.out.println("Cell Value "+ columndata2);

just check out if you have this problem "vt-x is disabled in bios"

in this case you need to enable virtualization technology bios

Call the class which has main() method.

java MyClass

Here MyClass will have public static void main() method.

Well I've tried all of the other answers and nothing is working for poor logcat. My issue with logcat is that it never worked to begin with. From the time I installed Android studio and finally was able to connect a device to adb it never gave me output. It's probably caused by my borked 32 bit Windows 7 setup though... So I wrote a batch script to run through the terminal to run apps with logcat.

adb shell am start -n "com.package.name/com.package.name.Activity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
adb shell pidof com.package.name > pid
for /f %%i in (pid) do (set pid=%%i)
echo %pid%
adb logcat *:V --pid=%pid%
ENDLOCAL

Put this with corrected directory paths and package names into a logcat.bat(or whatever.bat) file.

place the file in your AndroidStudioProjects/package_name/ folder then you can run

C:\User\me\AndroidStudioProjects\package_name>logcat(or whatever)

in the terminal.

Note that you can change what the logcat displays by changing

*:V

In the adb logcat command. (example *:E shows only (E)rror tags).

I hope this was helpful to someone else.

In case the container is already running:

docker exec -it container_id_or_name ash

For readonly/disabled and other attributes with true/false values

$(':submit').attr('disabled', function(_, attr){ return !attr});

The displayed error

after that import react

Finally import react-dom

if error is react is not define,please add ==>import React from 'react';

if error is reactDOM is not define,please add ==>import ReactDOM from 'react-dom';

If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:

plt.axes[0].get_lines()[0].set_color('black')

Please try this

<?php
$json_string = 'http://www.domain.com/jsondata.json';

$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata, true);
echo "<pre>"; print_r($obj['Result']);
?>

You can use Ctrl + /. This works for me.

Seems like problem of the old smtplib. In python2.7 everything works fine.

Update: Yep, server.ehlo() also could help.

UPDATE: setuptools has absorbed distribute as opposed to the other way around, as some thought. setuptools is up-to-date with the latest distutils changes and the wheel format. Hence, easy_install and pip are more or less on equal footing now.

std::vector has a constructor that takes two iterators. You can use that:

std::string str = "hello";
std::vector<char> data(str.begin(), str.end());

If you already have a vector and want to add the characters at the end, you need a back inserter:

std::string str = "hello";
std::vector<char> data = /* ... */;
std::copy(str.begin(), str.end(), std::back_inserter(data));

<input type="text" required="true" value="" readonly>

Not the.

<input type="text" required="true" value="" readonly="true">

The best way to do it is:

return this.StatusCode(StatusCodes.Status418ImATeapot, "Error message");

'StatusCodes' has every kind of return status and you can see all of them in this link https://httpstatuses.com/

Once you choose your StatusCode, return it with a message.

May be use like this

if($match > 0){
 $msg = 'Login Complete! Thanks';
 echo "<a href='".$link_address."'>link</a>";
 }
else{
 $msg = 'Login Failed!<br /> Please make sure that you enter the correct  details and that you have activated your account.';
}

answers above are good enough to show how to build the library, but how to collect the headers are still tricky. here I share the little script I use to copy the necessary headers.

SOURCE is the first param, which is the tensorflow source(build) direcoty;
DST is the second param, which is the include directory holds the collected headers. (eg. in cmake, include_directories(./collected_headers_here)).

#!/bin/bash

SOURCE=$1
DST=$2
echo "-- target dir is $DST"
echo "-- source dir is $SOURCE"

if [[ -e $DST ]];then
    echo "clean $DST"
    rm -rf $DST
    mkdir $DST
fi


# 1. copy the source code c++ api needs
mkdir -p $DST/tensorflow
cp -r $SOURCE/tensorflow/core $DST/tensorflow
cp -r $SOURCE/tensorflow/cc $DST/tensorflow
cp -r $SOURCE/tensorflow/c $DST/tensorflow

# 2. copy the generated code, put them back to
# the right directories along side the source code
if [[ -e $SOURCE/bazel-genfiles/tensorflow ]];then
    prefix="$SOURCE/bazel-genfiles/tensorflow"
    from=$(expr $(echo -n $prefix | wc -m) + 1)

    # eg. compiled protobuf files
    find $SOURCE/bazel-genfiles/tensorflow -type f | while read line;do
        #echo "procese file --> $line"
        line_len=$(echo -n $line | wc -m)
        filename=$(echo $line | rev | cut -d'/' -f1 | rev )
        filename_len=$(echo -n $filename | wc -m)
        to=$(expr $line_len - $filename_len)

        target_dir=$(echo $line | cut -c$from-$to)
        #echo "[$filename] copy $line $DST/tensorflow/$target_dir"
        cp $line $DST/tensorflow/$target_dir
    done
fi


# 3. copy third party files. Why?
# In the tf source code, you can see #include "third_party/...", so you need it
cp -r $SOURCE/third_party $DST

# 4. these headers are enough for me now.
# if your compiler complains missing headers, maybe you can find it in bazel-tensorflow/external
cp -RLf $SOURCE/bazel-tensorflow/external/eigen_archive/Eigen $DST
cp -RLf $SOURCE/bazel-tensorflow/external/eigen_archive/unsupported $DST
cp -RLf $SOURCE/bazel-tensorflow/external/protobuf_archive/src/google $DST
cp -RLf $SOURCE/bazel-tensorflow/external/com_google_absl/absl $DST

Try to use ftp.nlst(dir).

However, note that if the folder is empty, it might throw an error:

files = []

try:
    files = ftp.nlst()
except ftplib.error_perm, resp:
    if str(resp) == "550 No files found":
        print "No files in this directory"
    else:
        raise

for f in files:
    print f

If you're looking to use the standard construct of element = element1 || element2 where JavaScript will return the first one that is truthy, you could do exactly that:

element = $('#someParentElement .somethingToBeFound') || $('#someParentElement .somethingElseToBeFound');

which would return the first element that is actually found. But a better way would probably be to use the jQuery selector comma construct (which returns an array of found elements) in this fashion:

element = $('#someParentElement').find('.somethingToBeFound, .somethingElseToBeFound')[0];

which will return the first found element.

I use that from time to time to find either an active element in a list or some default element if there is no active element. For example:

element = $('ul#someList').find('li.active, li:first')[0] 

which will return any li with a class of active or, should there be none, will just return the last li.

Either will work. There are potential performance penalties, though, as the || will stop processing as soon as it finds something truthy whereas the array approach will try to find all elements even if it has found one already. Then again, using the || construct could potentially have performance issues if it has to go through several selectors before finding the one it will return, because it has to call the main jQuery object for each one (I really don't know if this is a performance hit or not, it just seems logical that it could be). In general, though, I use the array approach when the selector is a rather long string.

t refers to the text mode. There is no difference between r and rt or w and wt since text mode is the default.

Documented here:

Character   Meaning
'r'     open for reading (default)
'w'     open for writing, truncating the file first
'x'     open for exclusive creation, failing if the file already exists
'a'     open for writing, appending to the end of the file if it exists
'b'     binary mode
't'     text mode (default)
'+'     open a disk file for updating (reading and writing)
'U'     universal newlines mode (deprecated)

The default mode is 'r' (open for reading text, synonym of 'rt').

Keep track of both states (hovered, focused) as true/false flags, and whenever one changes, run a function that removes border if both are false, otherwise shows border.

So: onfocus sets focused = true, onblur sets focused = false. onmouseover sets hovered = true, onmouseout sets hovered = false. After each of these events run a function that adds/removes border.

You can use pandas.cut:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
   percentage     binned
0       46.50   (25, 50]
1       44.20   (25, 50]
2      100.00  (50, 100]
3       42.12   (25, 50]

bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
   percentage binned
0       46.50      5
1       44.20      5
2      100.00      6
3       42.12      5

Or numpy.searchsorted:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
   percentage  binned
0       46.50       5
1       44.20       5
2      100.00       6
3       42.12       5

...and then value_counts or groupby and aggregate size:

s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50]     3
(50, 100]    1
(10, 25]     0
(5, 10]      0
(1, 5]       0
(0, 1]       0
Name: percentage, dtype: int64

s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1]       0
(1, 5]       0
(5, 10]      0
(10, 25]     0
(25, 50]     3
(50, 100]    1
dtype: int64

By default cut return categorical.

Series methods like Series.value_counts() will use all categories, even if some categories are not present in the data, operations in categorical.

Thanks to Siarhei Kuchuk for his post. Even tho I've simplified the usage this initial code was very useful for me.

If your signatures differ only in the number of arguments, using default arguments is the right way to do it. If you want to be able to pass in different kinds of argument, I would try to avoid the isinstance-based approach mentioned in another answer, and instead use keyword arguments.

If using just keyword arguments becomes unwieldy, you can combine it with classmethods (the bzrlib code likes this approach). This is just a silly example, but I hope you get the idea:

class C(object):

    def __init__(self, fd):
        # Assume fd is a file-like object.
        self.fd = fd

    @classmethod
    def fromfilename(cls, name):
        return cls(open(name, 'rb'))

# Now you can do:
c = C(fd)
# or:
c = C.fromfilename('a filename')

Notice all those classmethods still go through the same __init__, but using classmethods can be much more convenient than having to remember what combinations of keyword arguments to __init__ work.

isinstance is best avoided because Python's duck typing makes it hard to figure out what kind of object was actually passed in. For example: if you want to take either a filename or a file-like object you cannot use isinstance(arg, file), because there are many file-like objects that do not subclass file (like the ones returned from urllib, or StringIO, or...). It's usually a better idea to just have the caller tell you explicitly what kind of object was meant, by using different keyword arguments.

It might be related to corruption in Angular Packages or incompatibility of packages.

Please follow the below steps to solve the issue.

• Delete node_modules folder manually.
• Install Node ( https://nodejs.org/en/download ).
• Install Yarn ( https://yarnpkg.com/en/docs/install ).
• Open command prompt , go to path angular folder and run Yarn.
• Run angular\nswag\refresh.bat.
• Run npm start from the angular folder.

Update

ASP.NET Boilerplate suggests here to use yarn because npm has some problems. It is slow and can not consistently resolve dependencies, yarn solves those problems and it is compatible to npm as well.

This can be addressed using the following LINQ expression:

var result = peopleList2.Where(p => !peopleList1.Any(p2 => p2.ID == p.ID));

An alternate way of expressing this via LINQ, which some developers find more readable:

var result = peopleList2.Where(p => peopleList1.All(p2 => p2.ID != p.ID));

Warning: As noted in the comments, these approaches mandate an O(n*m) operation. That may be fine, but could introduce performance issues, and especially if the data set is quite large. If this doesn't satisfy your performance requirements, you may need to evaluate other options. Since the stated requirement is for a solution in LINQ, however, those options aren't explored here. As always, evaluate any approach against the performance requirements your project might have.

Vertical alignment doesn't work with floated elements, indeed. That's because float lifts the element from the normal flow of the document. You might want to use other vertical aligning techniques, like the ones based on transform, display: table, absolute positioning, line-height, js (last resort maybe) or even the plain old html table (maybe the first choice if the content is actually tabular). You'll find that there's a heated debate on this issue.

However, this is how you can vertically align YOUR 3 divs:

.wrap{
    width: 500px;
    overflow:hidden;    
    background: pink;
}

.left {
    width: 150px;       
    margin-right: 10px;
    background: yellow;  
    display:inline-block;
    vertical-align: middle; 
}

.left2 {
    width: 150px;    
    margin-right: 10px;
    background: aqua; 
    display:inline-block;
    vertical-align: middle; 
}

.right{
    width: 150px;
    background: orange;
    display:inline-block;
    vertical-align: middle; 
}

Not sure why you needed both fixed width, display: inline-block and floating.

This error would occur if any of the following variables were actually strings or null instead of arrays, in which case accessing them with an array syntax $var[$i] would be like trying to access a specific character in a string:

$catagory
$task
$fullText
$dueDate
$empId

In short, everything in your insert query.

Perhaps the $catagory variable is misspelled?

In order to set textColor, BottomNavigationView has two style properties you can set directly from the xml:

• itemTextAppearanceActive
• itemTextAppearanceInactive

In your layout.xml file:

<com.google.android.material.bottomnavigation.BottomNavigationView
            android:id="@+id/bnvMainNavigation"
            style="@style/NavigationView"/>
  

In your styles.xml file:

    <style name="NavigationView" parent="Widget.MaterialComponents.BottomNavigationView">
      <item name="itemTextAppearanceActive">@style/ActiveText</item>
      <item name="itemTextAppearanceInactive">@style/InactiveText</item>
    </style>
    <style name="ActiveText">
      <item name="android:textColor">@color/colorPrimary</item>
    </style>
    <style name="InactiveText">
      <item name="android:textColor">@color/colorBaseBlack</item>
    </style>

For those of you on Windows using TortoiseGit, you can get a somewhat visual comparison through this rather obscure feature:

1. Navigate to the folder you want to compare
2. Hold down shift and right-click it
3. Go to TortoiseGit -> Browse Reference
4. Use ctrl to select two branches to compare
5. Right-click your selection and click "Compare selected refs"

        }

        // Draw child`s
        super.dispatchDraw(canvas);
    }


}

use Tag in xml like this:

<yourpackagename.ShadowLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal"
        app:sl_shadow_color="#9e000000"
        app:sl_shadow_radius="4dp">
<child views>
</yourpackagename.ShadowLayout>

UPDATE

put the below code in attrs.xml in resource>>values

  <declare-styleable name="ShadowLayout">
    <attr name="sl_shadowed" format="boolean"/>
    <attr name="sl_shadow_distance" format="dimension"/>
    <attr name="sl_shadow_angle" format="integer"/>
    <attr name="sl_shadow_radius" format="dimension"/>
    <attr name="sl_shadow_color" format="color"/>
</declare-styleable>

Android Studio Users:

If you want to use grade, go to http://search.maven.org/ and search for your maven repo. Then, click on the "latest version" and in the details page on the bottom left you will see "Gradle" where you can then copy/paste that link into your app's build.gradle.

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

Here a simple and easy solution on Angular JS using ng-repeat that might help.

var app = angular.module('myapp', []);_x000D_
_x000D_
app.controller('MainCtrl', function($scope) {_x000D_
_x000D_
  $scope.arr= [_x000D_
    {name:"Head1",desc:"Head1Desc"},_x000D_
    {name:"Head2",desc:"Head2Desc"},_x000D_
    {name:"Head3",desc:"Head3Desc"},_x000D_
    {name:"Head4",desc:"Head4Desc"}_x000D_
    ];_x000D_
    _x000D_
    $scope.collapseIt = function(id){_x000D_
      $scope.collapseId = ($scope.collapseId==id)?-1:id;_x000D_
    }_x000D_
});

Checking it out in python3:

python -V
Python 3.6.5

Example1:

.
+-- parent.py
+-- start.py
+-- sub
    +-- relative.py

- start.py
import sub.relative

- parent.py
print('Hello from parent.py')

- sub/relative.py
from .. import parent

If we run it like this(just to make sure PYTHONPATH is empty):

PYTHONPATH='' python3 start.py

Output:

Traceback (most recent call last):
  File "start.py", line 1, in <module>
    import sub.relative
  File "/python-import-examples/so-example-v1/sub/relative.py", line 1, in <module>
    from .. import parent
ValueError: attempted relative import beyond top-level package

If we change import in sub/relative.py

- sub/relative.py
import parent

If we run it like this:

PYTHONPATH='' python3 start.py

Output:

Hello from parent.py

Example2:

.
+-- parent.py
+-- sub
    +-- relative.py
    +-- start.py

- parent.py
print('Hello from parent.py')

- sub/relative.py
print('Hello from relative.py')

- sub/start.py
import relative
from .. import parent

Run it like:

PYTHONPATH='' python3 sub/start.py

Output:

Hello from relative.py
Traceback (most recent call last):
  File "sub/start.py", line 2, in <module>
    from .. import parent
ValueError: attempted relative import beyond top-level package

If we change import in sub/start.py:

- sub/start.py
import relative
import parent

Run it like:

PYTHONPATH='' python3 sub/start.py

Output:

Hello from relative.py
Traceback (most recent call last):
  File "sub/start.py", line 3, in <module>
    import parent
ModuleNotFoundError: No module named 'parent'

Run it like:

PYTHONPATH='.' python3 sub/start.py

Output:

Hello from relative.py
Hello from parent.py

Also it's better to use import from root folder, i.e.:

- sub/start.py
import sub.relative
import parent

Run it like:

PYTHONPATH='.' python3 sub/start.py

Output:

Hello from relative.py
Hello from parent.py

This worked in MySQL Workbench 6.0

System.Convert.IsDbNull][1](table.rows[0][0]);

IIRC, the (table.rows[0][0] == null) won't work, as DbNull.Value != null;

This worked for me just now:

<canvas id="c" height="100" width="100" style="border:1px solid red"></canvas>
<script>
var c = document.getElementById('c');
alert(c.height + ' ' + c.width);
c.height = 200;
c.width = 200;
alert(c.height + ' ' + c.width);
</script>

import os
p = os.path.abspath('..')

C:\ ---> C:\\\

The issue is it is missing Dynamic Web Module facet definition. Run the following at command line

mvn eclipse:eclipse -Dwtpversion=2.0

After build is success, refresh the project and you will be add the web project to server.

Python 3.6

Just to make it clear, you can use f-string formatting. This has almost the same syntax as the format method, but make it a bit nicer.

Example:

print(f'{numvar:.9f}')

More reading about the new f string:

• PEP official documentation
• Python official documentation
• Really good blog post - talks about performance too

Here is a diagram of the execution times of the various tested methods (from last link above):

The general explanation is provided in the link from Dan.

For specific questions your ask :

They can reside on the same machine, even in the same process (JVM for Java). It is a logical distinction (what they do?), not a physical one (where they are?).

jezrael's answer is good, but did not answer a question I had: Will getting the "sort" flag wrong mess up my data in any way? The answer is apparently "no", you are fine either way.

from pandas import DataFrame, concat

a = DataFrame([{'a':1,      'c':2,'d':3      }])
b = DataFrame([{'a':4,'b':5,      'd':6,'e':7}])

>>> concat([a,b],sort=False)
   a    c  d    b    e
0  1  2.0  3  NaN  NaN
0  4  NaN  6  5.0  7.0

>>> concat([a,b],sort=True)
   a    b    c  d    e
0  1  NaN  2.0  3  NaN
0  4  5.0  NaN  6  7.0

If you are using tortoise git.

please follow the below steps.

1. Checkout BranchB
2. Open project folder, go to TortoiseGit --> Pull
3. In pull screen, Change the remote branch "BranchA" and click ok.
4. Then right click again, go to TortoiseGit --> Push.

Now your changes moved from BranchA to BranchB

The simplest approach would be to use LINQ:

var count = text.TakeWhile(c => c == '$').Count();

There are certainly more efficient approaches, but that's probably the simplest.

You can use the tag canvas and "draw" the background, which work on IE9, Gecko and Webkit.

It means that if x is set, the value for z will be x, otherwise if y is set then its value will be set as the z's value.

it's the same as

if(x)
  z = x;
else
  z = y;

It's possible because logical operators in JavaScript doesn't return boolean values but the value of the last element needed to complete the operation (in an OR sentence it would be the first non-false value, in an AND sentence it would be the last one). If the operation fails, then false is returned.

you can use following helper function:

function content(divSelector, value) {
    document.querySelector(divSelector).innerHTML = value;
}

content('#content',"whatever");

Where #content must be valid CSS selector

Here is working example.

Additionaly - today (2018.07.01) I made speed comparison for jquery and pure js solutions ( MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit) ):

document.getElementById("content").innerHTML = "whatever"; // pure JS
$('#content').html('whatever');                            // jQuery

The jquery solution was slower than pure js solution: 69% on firefox, 61% on safari, 56% on chrome. The fastest browser for pure js was firefox with 560M operations per second, the second was safari 426M, and slowest was chrome 122M.

So the winners are pure js and firefox (3x faster than chrome!)

You can test it in your machine: https://jsperf.com/js-jquery-html-content-change

You can do this in CSS:

a.menu_links {
    cursor: pointer;
}

This is actually the default behavior for links. You must have either somehow overridden it elsewhere in your CSS, or there's no href attribute in there (it's missing from your example).

RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.
