as suggested, you can use 'die and dump' such as

dd($var)

or only 'dump', without dying,

dump($var)

Circular imports cause problems, but Python has ways to mitigate it built-in.

The problem is when you run python a.py, it runs a.py but not mark it imported as a module. So in turn a.py -> imports module b -> imports module a -> imports module b. The last import a no-op since b is currently being imported and Python guards against that. And b is an empty module for now. So when it executes b.hi(), it can't find anything.

Note that the b.hi() that got executed is during a.py -> module b -> module a, not in a.py directly.

In your specific example, you can just run python -c 'import a' at top-level, so the first execution of a.py is registered as importing a module.

The (A==B).all() solution is very neat, but there are some built-in functions for this task. Namely array_equal, allclose and array_equiv.

(Although, some quick testing with timeit seems to indicate that the (A==B).all() method is the fastest, which is a little peculiar, given it has to allocate a whole new array.)

Java 1.8 version has nice update for data time API.

Here is snippet of code:

    LocalDate lastAprilDay = LocalDate.of(2014, Month.APRIL, 30);
    System.out.println("last april day: " + lastAprilDay);
    LocalDate firstMay = lastAprilDay.plusDays(1);
    System.out.println("should be first may day: " + firstMay);
    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd");
    String formatDate = formatter.format(firstMay);
    System.out.println("formatted date: " + formatDate);

Output:

last april day: 2014-04-30
should be first may day: 2014-05-01
formatted date: 01

For more info see Java documentations to this classes:

• LocalDate

I've created a recursive function based on regex, in case you don't want to install library and understand the logic behind what's happening:

const xmlSample = '<tag>tag content</tag><tag2>another content</tag2><tag3><insideTag>inside content</insideTag><emptyTag /></tag3>';_x000D_
console.log(parseXmlToJson(xmlSample));_x000D_
_x000D_
function parseXmlToJson(xml) {_x000D_
    const json = {};_x000D_
    for (const res of xml.matchAll(/(?:<(\w*)(?:\s[^>]*)*>)((?:(?!<\1).)*)(?:<\/\1>)|<(\w*)(?:\s*)*\/>/gm)) {_x000D_
        const key = res[1] || res[3];_x000D_
        const value = res[2] && parseXmlToJson(res[2]);_x000D_
        json[key] = ((value && Object.keys(value).length) ? value : res[2]) || null;_x000D_
_x000D_
    }_x000D_
    return json;_x000D_
}

Regex explanation for each loop:

• res[0] - return the xml (as is)
• res[1] - return the xml tag name
• res[2] - return the xml content
• res[3] - return the xml tag name in case the tag closes itself. In example: <tag />

You can check how the regex works here: https://regex101.com/r/ZJpCAL/1

Note: In case json has a key with an undefined value, it is being removed. That's why I've inserted null at the end of line 9.

Go with the following if you really want to use a loop. Nobody has actually answered how to feed data in a loop:

def plot(data):
    fig = plt.figure(figsize=(100, 100))
    for idx, k in enumerate(data.keys(), 1):
        x, y = data[k].keys(), data[k].values
        plt.subplot(63, 10, idx)
        plt.bar(x, y)  
    plt.show()

getTime() retrieves the milliseconds since Jan 1, 1970 GMT passed to the constructor. It should not be too hard to get the Unix time (same, but in seconds) from that.

Yes - older POSIX standards defined usleep(), so this is available on Linux:

int usleep(useconds_t usec);

DESCRIPTION

The usleep() function suspends execution of the calling thread for (at least) usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers.

usleep() takes microseconds, so you will have to multiply the input by 1000 in order to sleep in milliseconds.

usleep() has since been deprecated and subsequently removed from POSIX; for new code, nanosleep() is preferred:

#include <time.h>

int nanosleep(const struct timespec *req, struct timespec *rem);

DESCRIPTION

nanosleep() suspends the execution of the calling thread until either at least the time specified in *req has elapsed, or the delivery of a signal that triggers the invocation of a handler in the calling thread or that terminates the process.

The structure timespec is used to specify intervals of time with nanosecond precision. It is defined as follows:

struct timespec {
    time_t tv_sec;        /* seconds */
    long   tv_nsec;       /* nanoseconds */
};

An example msleep() function implemented using nanosleep(), continuing the sleep if it is interrupted by a signal:

#include <time.h>
#include <errno.h>    

/* msleep(): Sleep for the requested number of milliseconds. */
int msleep(long msec)
{
    struct timespec ts;
    int res;

    if (msec < 0)
    {
        errno = EINVAL;
        return -1;
    }

    ts.tv_sec = msec / 1000;
    ts.tv_nsec = (msec % 1000) * 1000000;

    do {
        res = nanosleep(&ts, &ts);
    } while (res && errno == EINTR);

    return res;
}

To indent any old JSON, just bind it as Object, like:

Object json = mapper.readValue(input, Object.class);

and then write it out with indentation:

String indented = mapper.writerWithDefaultPrettyPrinter().writeValueAsString(json);

this avoids your having to define actual POJO to map data to.

Or you can use JsonNode (JSON Tree) as well.

DiffUtil can the best choice for updating the data in the RecyclerView Adapter which you can find in the android framework. DiffUtil is a utility class that can calculate the difference between two lists and output a list of update operations that converts the first list into the second one.

Most of the time our list changes completely and we set new list to RecyclerView Adapter. And we call notifyDataSetChanged to update adapter. NotifyDataSetChanged is costly. DiffUtil class solves that problem now. It does its job perfectly!

I have never developed with HangOut. I ran into the same problems with FB-login and I was trying so hard to get it to click programatically. Then later I discovered that the sdk won't allow you to programatically click the button because of some security reasons. The user has to physically click on the button. This also happens with async asp fileupload button. So please check if HangOut does allow you to programatically click a buttton. All above codes are correct and they should work. If you dig deep enough you will see that my answer is the right answer for your situation you.

The snippet below sorts given map by its keys and maps the keys to key-value objects again. I used localeCompare function since my map was string->string object map.

var hash = {'x': 'xx', 't': 'tt', 'y': 'yy'};
Object.keys(hash).sort((a, b) => a.localeCompare(b)).map(function (i) {
            var o = {};
            o[i] = hash[i];
            return o;
        });

result: [{t:'tt'}, {x:'xx'}, {y: 'yy'}];

I believe you need subexpressions. If I remember right you can use the normal () brackets for subexpressions.

This part is From grep manual:

 Back References and Subexpressions
       The back-reference \n, where n is a single digit, matches the substring
       previously matched  by  the  nth  parenthesized  subexpression  of  the
       regular expression.

Do something like ^[^(abc)] should do the trick.

Dates in VBA are just floating point numbers, where the integer part represents the date and the fraction part represents the time. So in addition to using the Date function as tlayton says (to get the current date) you can also cast a date value to a integer to get the date-part from an arbitrary date: Int(myDateValue).

The solution is to make it readable only by the owner of the file, i.e. the last two digits of the octal mode representation should be zero (e.g. mode 0400).

OpenSSH checks this in authfile.c, in a function named sshkey_perm_ok:

/*
 * if a key owned by the user is accessed, then we check the
 * permissions of the file. if the key owned by a different user,
 * then we don't care.
 */
if ((st.st_uid == getuid()) && (st.st_mode & 077) != 0) {
    error("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");
    error("@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @");
    error("@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@");
    error("Permissions 0%3.3o for '%s' are too open.",
        (u_int)st.st_mode & 0777, filename);
    error("It is required that your private key files are NOT accessible by others.");
    error("This private key will be ignored.");
    return SSH_ERR_KEY_BAD_PERMISSIONS;
}

See the first line after the comment: it does a "bitwise and" against the mode of the file, selecting all bits in the last two octal digits (since 07 is octal for 0b111, where each bit stands for r/w/x, respectively).

I do this to create my own validation annotation and validator:

ValidCardType.java(annotation to put on methods/fields)

@Constraint(validatedBy = {CardTypeValidator.class})
@Documented
@Target( { ElementType.ANNOTATION_TYPE, ElementType.METHOD, ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
public @interface ValidCardType {
    String message() default "Incorrect card type, should be among: \"MasterCard\" | \"Visa\"";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

And, the validator to trigger the check: CardTypeValidator.java:

public class CardTypeValidator implements ConstraintValidator<ValidCardType, String> {
    private static final String[] ALL_CARD_TYPES = {"MasterCard", "Visa"};

    @Override
    public void initialize(ValidCardType status) {
    }
    public boolean isValid(String value, ConstraintValidatorContext context) {
        return (Arrays.asList(ALL_CARD_TYPES).contains(value));
    }
}

You can do something very similar to check @NotNull.

This may be useful:

var serializer = new JavaScriptSerializer();
dynamic jsonObject = serializer.Deserialize<dynamic>(json);

Where "json" is the string that contains the JSON values. Then to retrieve the values from the jsonObject you may use

myProperty = Convert.MyPropertyType(jsonObject["myProperty"]);

Changing MyPropertyType to the proper type (ToInt32, ToString, ToBoolean, etc).

Given:

A_1 = [10 200 7 150]';
A_2 = [0.001 0.450 0.007 0.200]';

(As others have already pointed out) There are tools to simply compute correlation, most obviously corr:

corr(A_1, A_2);  %Returns 0.956766573975184  (Requires stats toolbox)

You can also use base Matlab's corrcoef function, like this:

M = corrcoef([A_1 A_2]):  %Returns [1 0.956766573975185; 0.956766573975185 1];
M(2,1);  %Returns 0.956766573975184 

Which is closely related to the cov function:

cov([condition(A_1) condition(A_2)]);

As you almost get to in your original question, you can scale and adjust the vectors yourself if you want, which gives a slightly better understanding of what is going on. First create a condition function which subtracts the mean, and divides by the standard deviation:

condition = @(x) (x-mean(x))./std(x);  %Function to subtract mean AND normalize standard deviation

Then the correlation appears to be (A_1 * A_2)/(A_1^2), like this:

(condition(A_1)' * condition(A_2)) / sum(condition(A_1).^2);  %Returns 0.956766573975185

By symmetry, this should also work

(condition(A_1)' * condition(A_2)) / sum(condition(A_2).^2); %Returns 0.956766573975185

And it does.

I believe, but don't have the energy to confirm right now, that the same math can be used to compute correlation and cross correlation terms when dealing with multi-dimensiotnal inputs, so long as care is taken when handling the dimensions and orientations of the input arrays.

            conn.connect();
            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            bm = BitmapFactory.decodeStream(bis);
            bis.close();

If you care about accuracy for small angles, you want to use this:

angle = 2*atan2(|| ||b||a - ||a||b ||, || ||b||a + ||a||b ||)

Where "||" means absolute value, AKA "length of the vector". See https://math.stackexchange.com/questions/1143354/numerically-stable-method-for-angle-between-3d-vectors/1782769

However, that has the downside that in two dimensions, it loses the sign of the angle.

MySQL says:

All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.

When do I use it ?

Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED data type.

A common mistake is to use a primary key that is an auto-increment INT starting at zero, yet the type is SIGNED, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.

See https://polarssl.org/kb/cryptography/asn1-key-structures-in-der-and-pem (search the page for "BEGIN RSA PRIVATE KEY") (archive link for posterity, just in case).

BEGIN RSA PRIVATE KEY is PKCS#1 and is just an RSA key. It is essentially just the key object from PKCS#8, but without the version or algorithm identifier in front. BEGIN PRIVATE KEY is PKCS#8 and indicates that the key type is included in the key data itself. From the link:

The unencrypted PKCS#8 encoded data starts and ends with the tags:

-----BEGIN PRIVATE KEY-----
BASE64 ENCODED DATA
-----END PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

PrivateKeyInfo ::= SEQUENCE {
  version         Version,
  algorithm       AlgorithmIdentifier,
  PrivateKey      BIT STRING
}

AlgorithmIdentifier ::= SEQUENCE {
  algorithm       OBJECT IDENTIFIER,
  parameters      ANY DEFINED BY algorithm OPTIONAL
}

So for an RSA private key, the OID is 1.2.840.113549.1.1.1 and there is a RSAPrivateKey as the PrivateKey key data bitstring.

As opposed to BEGIN RSA PRIVATE KEY, which always specifies an RSA key and therefore doesn't include a key type OID. BEGIN RSA PRIVATE KEY is PKCS#1:

RSA Private Key file (PKCS#1)

The RSA private key PEM file is specific for RSA keys.

It starts and ends with the tags:

-----BEGIN RSA PRIVATE KEY-----
BASE64 ENCODED DATA
-----END RSA PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

RSAPrivateKey ::= SEQUENCE {
  version           Version,
  modulus           INTEGER,  -- n
  publicExponent    INTEGER,  -- e
  privateExponent   INTEGER,  -- d
  prime1            INTEGER,  -- p
  prime2            INTEGER,  -- q
  exponent1         INTEGER,  -- d mod (p-1)
  exponent2         INTEGER,  -- d mod (q-1)
  coefficient       INTEGER,  -- (inverse of q) mod p
  otherPrimeInfos   OtherPrimeInfos OPTIONAL
}

One way is:

application arg0 arg1 > temp.txt
set /p VAR=<temp.txt

Another is:

for /f %%i in ('application arg0 arg1') do set VAR=%%i

Note that the first % in %%i is used to escape the % after it and is needed when using the above code in a batch file rather than on the command line. Imagine, your test.bat has something like:

for /f %%i in ('c:\cygwin64\bin\date.exe +"%%Y%%m%%d%%H%%M%%S"') do set datetime=%%i
echo %datetime%

Things have changed in the last years. The answers above are not valid in all cases any more. Apple is pushing disappearing scrollbars everywhere. Safari, Chrome and even Firefox on MacOs (and iOs) only show scrollbars when actually scrolling — I don't know about current Windows/IE. However there are non-standard ways to style scroll bars on Webkit (IE dropped that a long time ago).

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

Default

The default Gson implementation of Map serialization uses toString() on the key:

Gson gson = new GsonBuilder()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will give:

{
  "java.awt.Point[x\u003d1,y\u003d2]": "a",
  "java.awt.Point[x\u003d3,y\u003d4]": "b"
}

Using enableComplexMapKeySerialization

If you want the Map Key to be serialized according to default Gson rules you can use enableComplexMapKeySerialization. This will return an array of arrays of key-value pairs:

Gson gson = new GsonBuilder().enableComplexMapKeySerialization()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will return:

[
  [
    {
      "x": 1,
      "y": 2
    },
    "a"
  ],
  [
    {

VT-x can normally be disabled/enabled in your BIOS.

When your PC is just starting up you should press DEL (or something) to get to the BIOS settings. There you'll find an option to enable VT-technology (or something).

I am going to use an example to add to the answers above.

I ran into proxy issues while trying to install packages via Web Platform Installer

That too uses a config file which is WebPlatformInstaller.exe.config

I tried the edits suggest in this IIS forum which is

<?xml version="1.0" encoding="utf-8" ?>
<configuration>  
  <system.net>    
     <defaultProxy enabled="True" useDefaultCredentials="True"/>      
   </system.net>
</configuration>

and

<?xml version="1.0" encoding="utf-8" ?>
<configuration>  
   <system.net>    
     <defaultProxy>      
          <proxy 
               proxyaddress="http://yourproxy.company.com:80" 
               usesystemdefault="True"
               autoDetect="False" />    
     </defaultProxy>  
   </system.net>
</configuration>

None of these worked.

What worked for me was this -

<system.net>    
    <defaultProxy enabled="true" useDefaultCredentials="false">
      <module type="WebPI.Net.AuthenticatedProxy, WebPI.Net, Version=1.0.0.0, Culture=neutral, PublicKeyToken=79a8d77199cbf3bc" />
    </defaultProxy>  
 </system.net>

The module needed to be registered with Web Platform Installer in order to use it.

The above answers are good, except they don't have proper tick placement on the colorbar. I like having the ticks in the middle of the color so that the number -> color mapping is more clear. You can solve this problem by changing the limits of the matshow call:

import matplotlib.pyplot as plt
import numpy as np

def discrete_matshow(data):
    #get discrete colormap
    cmap = plt.get_cmap('RdBu', np.max(data)-np.min(data)+1)
    # set limits .5 outside true range
    mat = plt.matshow(data,cmap=cmap,vmin = np.min(data)-.5, vmax = np.max(data)+.5)
    #tell the colorbar to tick at integers
    cax = plt.colorbar(mat, ticks=np.arange(np.min(data),np.max(data)+1))

#generate data
a=np.random.randint(1, 9, size=(10, 10))
discrete_matshow(a)

yes, you can have associative arrays also in javascript:

var obj = 
{
    name:'some name',
    otherProperty:'prop value',
    date: new Date()
};
for(i in obj)
{
    var propVal = obj[i]; // i is the key, and obj[i] is the value ...
}

And for my fellow Europeans, try using this:

timestamp=$(date +%d-%m-%Y_%H-%M-%S)

will give a format of the format: "15-02-2020_19-21-58"

You call the variable and get the string representation like this

$timestamp

A solution I decided on involved the use of a boolean variable to track if the for loop should process its instructions or skip to the next iteration:

Dim continue

For Each item In collection
    continue = True

    If condition1 Then continue = False End If

    If continue Then
        'Do work
    End If
Next

I found the nested loop solutions to be somewhat confusing readability wise. This method also has its own pitfalls since the loop doesn't immediately skip to the next iteration after encountering continue. It would be possible for a later condition to reverse the state of continue. It also has a secondary construct within the initial loop, and requires the declaration of an extra var.

Oh, VBScript...sigh.

Also, if you want to use the accepted answer, which isn't too bad readability wise, you could couple that with the use of : to merge the two loops into what appears to be one:

Dim i

For i = 0 To 10 : Do
    If i = 4 Then Exit Do
    WScript.Echo i
Loop While False : Next

I found it useful to eliminate the extra level of indentation.

You have to use g++ (as mentioned in other answers). On top of that you can think of providing some good options available at command line (which helps you avoid making ill formed code):

g++   -O4    -Wall hi.cpp -o hi.out
     ^^^^^   ^^^^^^
  optimize  related to coding mistakes

For more detail you can refer to man g++ | less.

You can use exit method to quit an ios app :

exit(0);

You should say same alert message and ask him to quit

Another way is by using [[NSThread mainThread] exit]

However you should not do this way

According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.

T-SQL

/* 
Stored Procedure GetstudentnameInOutputVariable is modified to collect the
email address of the student with the help of the Alert Keyword
*/



CREATE  PROCEDURE GetstudentnameInOutputVariable
(

@studentid INT,                   --Input parameter ,  Studentid of the student
@studentname VARCHAR (200) OUT,    -- Output parameter to collect the student name
@StudentEmail VARCHAR (200)OUT     -- Output Parameter to collect the student email
)
AS
BEGIN
SELECT @studentname= Firstname+' '+Lastname, 
    @StudentEmail=email FROM tbl_Students WHERE studentid=@studentid
END

You can use the asList method with varargs to do this in one line:

java.util.Arrays.asList('+', '-', '*', '^');

If the list does not need to be modified further then this would already be enough. Otherwise you can pass it to the ArrayList constructor to create a mutable list:

new ArrayList(Arrays.asList('+', '-', '*', '^'));

For getting the directory 2 levels up:

 import os.path as path
 two_up = path.abspath(path.join(os.getcwd(),"../.."))

you may try:

head -1 stores.dat | grep -o \|  | wc -l

Once id of iframe is set, you can access iframe from inner document as shown below.

var iframe = parent.document.getElementById(frameElement.id);

Works well in IE, Chrome and FF.

What you are asking is possible; but that will only work on a specific browser. You have to develop a browser extension app to achieve this. You can read more about chrome api to understand better. https://developer.chrome.com/extensions/cookies

import os
for subdir, dirs, files in os.walk('./'):
    for file in files:
      do some stuff
      print file

You can improve this code with del dirs[:]which will be like following .

import os
for subdir, dirs, files in os.walk('./'):
    del dirs[:]
    for file in files:
      do some stuff
      print file

Or even better if you could point os.walk with current working directory .

import os
cwd = os.getcwd()
for subdir, dirs, files in os.walk(cwd, topdown=True):
    del dirs[:]  # remove the sub directories.
    for file in files:
      do some stuff
      print file

I always prefer List and I use "fold/reduce" before "for comprehension". However, "for comprehension" is preferred if nested "folds" are required. Recursion is the last resort if I can not accomplish the task using "fold/reduce/for".

so for your example, I will do:

((0 to 3) :\ List[Int]())(_ :: _)

before I do:

(for (x <- 0 to 3) yield x).toList

Note: I use "foldRight(:\)" instead of "foldLeft(/:)" here because of the order of "_"s. For a version that does not throw StackOverflowException, use "foldLeft" instead.

For BootsTrap Calender use this

/The Calender Index CSS/

.bootstrap-datetimepicker-widget {
   z-index:99999 !important;
}

document.write(`<td width='74'><button id='button' type='button' onclick='myfunction(\``+ name + `\`)'>click</button></td>`)

Better to use `` than "". This is a more dynamic answer.

#import "YourViewController.h"

To push a view including the navigation bar and/or tab bar:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"YourStoryboard" bundle:nil];
YourViewController *viewController = (YourViewcontroller *)[storyboard instantiateViewControllerWithIdentifier:@"YourViewControllerIdentifier"];
[self.navigationController pushViewController:viewController animated:YES];

To set identifier to a view controller, Open YourStoryboard.storyboard. Select YourViewController View-> Utilities -> ShowIdentityInspector. There you can specify the identifier.

Use Excel Online (Google Sheets).. And install Power Tools for Google Sheets.. Then in Google Sheets go to Addons tab and start Power Tools. Then choose Randomize from Power Tools menu. Select Shuffle. Then select choices of your test in excel sheet. Then select Cells in each row and click Shuffle from Power Tools menu. This will shuffle each row's selected cells independently from one another.

Seq.empty[String].toDF()

I needed to copy a table from one database another database. For anyone using a GUI like Sequel Ace you can right click table and click 'copy create table syntax' and run that query (you can edit the query, e.g. change table name, remove foreign keys, add/remove columns if desired)

It's just a basic operation.

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

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

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

I had a similar issue and found that pandas.get_dummies() solved the problem. Specifically, it splits out columns of categorical data into sets of boolean columns, one new column for each unique value in each input column. In your case, you would replace train_x = test[cols] with:

train_x = pandas.get_dummies(test[cols])

This transforms the train_x Dataframe into the following form, which RandomForestClassifier can accept:

   C  A_Hello  A_Hola  B_Bueno  B_Hi
0  0        1       0        0     1
1  1        0       1        1     0

for(var property in data) {
    alert(property);
}

It is not the asker's problem in this instance but the first troubleshooting step for a generic "AttributeError: __exit__" should be making sure the brackets are there, e.g.

with SomeContextManager() as foo:
    #works because a new object is referenced...

not

with SomeContextManager as foo:
    #AttributeError because the class is referenced

Catches me out from time to time and I end up here -__-

I know this is an old question but I just want to comment here: To any extent email addresses ARE case sensitive, most users would be "very unwise" to actively use an email address that requires capitals. They would soon stop using the address because they'd be missing a lot of their mail. (Unless they have a specific reason to make things difficult, and they expect mail only from specific senders they know.)

That's because imperfect humans as well as imperfect software exist, (Surprise!) which will assume all email is lowercase, and for this reason these humans and software will send messages using a "lower cased version" of the address regardless of how it was provided to them. If the recipient is unable to receive such messages, it won't be long before they notice they're missing a lot, and switch to a lowercase-only email address, or get their server set up to be case-insensitive.

I liked the fileinput approach as explained in this answer: Deleting a line from a text file (python)

Say for example I have a file which has empty lines in it and I want to remove empty lines, here's how I solved it:

import fileinput
import sys
for line_number, line in enumerate(fileinput.input('file1.txt', inplace=1)):
    if len(line) > 1:
            sys.stdout.write(line)

Note: The empty lines in my case had length 1

I know that two threads can not enter in Synchronize block at the same time

Two thread cannot enter a synchronized block on the same object twice. This means that two threads can enter the same block on different objects. This confusion can lead to code like this.

private Integer i = 0;

synchronized(i) {
   i++;
}

This will not behave as expected as it could be locking on a different object each time.

if this is true than How this atomic.incrementAndGet() works without Synchronize ?? and is thread safe ??

yes. It doesn't use locking to achieve thread safety.

If you want to know how they work in more detail, you can read the code for them.

And what is difference between internal reading and writing to Volatile Variable / Atomic Variable ??

Atomic class uses volatile fields. There is no difference in the field. The difference is the operations performed. The Atomic classes use CompareAndSwap or CAS operations.

i read in some article that thread has local copy of variables what is that ??

I can only assume that it referring to the fact that each CPU has its own cached view of memory which can be different from every other CPU. To ensure that your CPU has a consistent view of data, you need to use thread safety techniques.

This is only an issue when memory is shared at least one thread updates it.

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

"dev" is not a string it is a const char * like var1. Thus you are indeed comparing the memory adresses. Being that var1 is a char pointer, *var1 is a single char (the first character of the pointed to character sequence to be precise). You can't compare a char against a char pointer, which is why that did not work.

Being that this is tagged as c++, it would be sensible to use std::string instead of char pointers, which would make == work as expected. (You would just need to do const std::string var1 instead of const char *var1.

pom packaging is simply a specification that states the primary artifact is not a war or jar, but the pom.xml itself.

Often it is used in conjunction with "modules" which are typically contained in sub-directories of the project in question; however, it may also be used in certain scenarios where no primary binary was meant to be built, all the other important artifacts have been declared as secondary artifacts

Think of a "documentation" project, the primary artifact might be a PDF, but it's already built, and the work to declare it as a secondary artifact might be desired over the configuration to tell maven how to build a PDF that doesn't need compiled.

It doesn't do any harm to delete a non-existing event handler. So if you know what handlers there might be, you can simply delete all of them. I just had similar case. This may help in some cases.

Like:

// Add handlers...
if (something)
{
    c.Click += DoesSomething;
}
else
{
    c.Click += DoesSomethingElse;
}

// Remove handlers...
c.Click -= DoesSomething;
c.Click -= DoesSomethingElse;

In this line:

Aboutme.Text = String.Format("{2}", reader.GetString(0));

The token {2} is invalid because you only have one item in the parms. Use this instead:

Aboutme.Text = String.Format("{0}", reader.GetString(0));

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

You can do any one of the below two methods:

1. Running the below command (most recommended way to remove your package without updating your other packages)

   $ composer remove vendor/package

2. Go to your composer.json file and then run command like below it will remove your package (but it will also update your other packages)

   $ composer update

CTRL+SHIFT+I brings up the developers tools.

You can use below SQL to read the BLOB Fields from table.

SELECT DBMS_LOB.SUBSTR(BLOB_FIELD_NAME) FROM TABLE_NAME;

This is my personal understanding about the topic.

For a project, we can do the version control by different repositories. And for a repository, it can manage a whole project or part of projects.

Regarding on your project (several prototype applications which are independent of each them). You can manage the project by one repository or by several repositories, the difference:

1. Manage by one repository. If one of the applications is changed, the whole project (all the applications) will be committed to a new version.

2. Manage by several repositories. If one application is changed, it will only affect the repository which manages the application. Version for other repositories was not changed.

I decided to just build controls dictionaries. Harder to maintain, might run faster than the recursive FindControl().

protected void Page_Load(object sender, EventArgs e)
{
  this.BuildControlDics();
}

private void BuildControlDics()
{
  _Divs = new Dictionary<MyEnum, HtmlContainerControl>();
  _Divs.Add(MyEnum.One, this.divOne);
  _Divs.Add(MyEnum.Two, this.divTwo);
  _Divs.Add(MyEnum.Three, this.divThree);

}

And before I get down-thumbs for not answering the OP's question...

Q: Now, my question is that is there any other way/solution to find the nested control in ASP.NET? A: Yes, avoid the need to search for them in the first place. Why search for things you already know are there? Better to build a system allowing reference of known objects.

Regarding the question,

” can someone explain why the compare() function exists if a comparison can be made using simple operands?

Relative to < and ==, the compare function is conceptually simpler and in practice it can be more efficient since it avoids two comparisons per item for ordinary ordering of items.

As an example of simplicity, for small integer values you can write a compare function like this:

auto compare( int a, int b ) -> int { return a - b; }

which is highly efficient.

Now for a structure

struct Foo
{
    int a;
    int b;
    int c;
};

auto compare( Foo const& x, Foo const& y )
    -> int
{
    if( int const r = compare( x.a, y.a ) ) { return r; }
    if( int const r = compare( x.b, y.b ) ) { return r; }
    return compare( x.c, y.c );
}

Trying to express this lexicographic compare directly in terms of < you wind up with horrendous complexity and inefficiency, relatively speaking.

With C++11, for the simplicity alone ordinary less-than comparison based lexicographic compare can be very simply implemented in terms of tuple comparison.

First of all you need to create a symbolic link for the storage directory using the artisan command

Swift 3:

Both .ics and .vcs files are in ASCII. If you use "Save As" option to save a calendar entry (Appt, Meeting Request/Response/Postpone/Cancel and etc) in both .ics and .vcs format and use vimdiff, you can easily see the difference.

Both .vcs (vCal) and .ics (iCal) belongs to the same VCALENDAR camp, but .vcs file shows "VERSION:1.0" whereas .ics file uses "VERSION:2.0".

The spec for vCalendar v1.0 can be found at http://www.imc.org/pdi/pdiproddev.html. The spec for iCalendar (vCalendar v2.0) is in RFC5545. In general, the newer is better, and that is true for Outlook 2007 and onward, but not for Outlook 2003.

For Outlook 2003, the behavior is peculiar. It can save the same calendar entry in both .ics and .vcs format, but it only read & display .vcs file correctly. It can read .ics file but it omits some fields and does not display it in calendar mode. My guess is that back then Microsoft wanted to provide .ics to be compatible with Mac's iCal but not quite committed to v2.0 yet.

So I would say for Outlook 2003, .vcs is the native format.

I found that I needed to have a default value, even if it was an empty string for it to work. So this:

this.registerForm('someName', {
  firstName: new FormControl({disabled: true}),
});

...had to become this:

this.registerForm('someName', {
  firstName: new FormControl({value: '', disabled: true}),
});

See my question (which I don't believe is a duplicate): Passing 'disabled' in form state object to FormControl constructor doesn't work

Here is a general solution that doesn't rely on JQuery. Simply modify the definition of window.location.

<html>
   <head>
      <script>
         function loadNewDoc(){ 
            var loc = window.location;
            window.location = loc.hostname + loc.port + loc.pathname + loc.search; 
         };
      </script>
   </head>
   <body onLoad="loadNewDoc()">
   </body>  
</html>

Yes, thanks to C# 7 that can be achieved. Here's how it's done (using expression pattern):

switch (o)
{
    case A a:
        a.Hop();
        break;
    case B b:
        b.Skip();
        break;
    case C _: 
        return new ArgumentException("Type C will be supported in the next version");
    default:
        return new ArgumentException("Unexpected type: " + o.GetType());
}

editied to add support for ie6:

Try

<img style="height:725px;max-width:500px;width: expression(this.width > 500 ? 500: true);" id="img_DocPreview" src="Images/empty.jpg" />

This should set the height to 725px but prevent the width from exceeding 500px. The width expression works around ie6 and is ignored by other browsers.

There is no direct equivalent to mvn exec:java in gradle, you need to either apply the application plugin or have a JavaExec task.

application plugin

Activate the plugin:

plugins {
    id 'application'
    ...
}

Configure it as follows:

application {
    mainClassName = project.hasProperty("mainClass") ? getProperty("mainClass") : "NULL"
}

On the command line, write

$ gradle -PmainClass=Boo run

JavaExec task

Define a task, let's say execute:

task execute(type:JavaExec) {
   main = project.hasProperty("mainClass") ? getProperty("mainClass") : "NULL"
   classpath = sourceSets.main.runtimeClasspath
}

To run, write gradle -PmainClass=Boo execute. You get

$ gradle -PmainClass=Boo execute
:compileJava
:compileGroovy UP-TO-DATE
:processResources UP-TO-DATE
:classes
:execute
I am BOO!

mainClass is a property passed in dynamically at command line. classpath is set to pickup the latest classes.

If you do not pass in the mainClass property, both of the approaches fail as expected.

$ gradle execute

FAILURE: Build failed with an exception.

* Where:
Build file 'xxxx/build.gradle' line: 4

* What went wrong:
A problem occurred evaluating root project 'Foo'.
> Could not find property 'mainClass' on task ':execute'.

sorted(list, key=lambda x: x[1])

Note: this works on time variable too.

you can do this in different ways:

1. Setting a timeout in the web service caller from code (not 100% sure but I think I have seen this done);
2. Setting a timeout in the constructor of the web service proxy in the web references;
3. Setting a timeout in the server side, web.config of the web service application.

see here for more details on the second case:

http://msdn.microsoft.com/en-us/library/ff647786.aspx#scalenetchapt10_topic14

and here for details on the last case:

How to increase the timeout to a web service request?

This happens because your local module named urllib.py shadows the installed requests module you are trying to use. The current directory is preapended to sys.path, so the local name takes precedence over the installed name.

An extra debugging tip when this comes up is to look at the Traceback carefully, and realize that the name of your script in question is matching the module you are trying to import.

Rename your file to something else like url.py. Then It is working fine. Hope it helps!

    var binary = [];
    var bytes = new Uint8Array(buffer);
    for (var i = 0, il = bytes.byteLength; i < il; i++) {
        binary.push(String.fromCharCode(bytes[i]));
    }
    return btoa(binary.join(''));
}


// example, it works also with astral plane characters such as ''
var encodedString = new TextEncoder().encode('?');
var base64String = u_btoa(encodedString);
console.log('?' === new TextDecoder().decode(u_atob(base64String)))

A trivial approach would be to replace

<[^>]*>

with nothing. But depending on how ill-structured your input is that may well fail.

You don't need to create a new datafile; you can extend your existing tablespace data files.

Execute the following to determine the filename for the existing tablespace:

  SELECT * FROM DBA_DATA_FILES;

Then extend the size of the datafile as follows (replace the filename with the one from the previous query):

  ALTER DATABASE DATAFILE 'D:\ORACLEXE\ORADATA\XE\SYSTEM.DBF' RESIZE 2048M; 

With your question edit, I see your problem. Let's say the current directory is /home/yourname ... in this case, your command below:

sed 's/xxx/'$PWD'/'

will be expanded to

sed `s/xxx//home/yourname//

which is not valid. You need to put a \ character in front of each / in your $PWD if you want to do this.

Example using std::string find method:

#include <iostream>
#include <string>

int main (){
    std::string str ("There are two needles in this haystack with needles.");
    std::string str2 ("needle");

    size_t found = str.find(str2);
    if(found!=std::string::npos){ 
        std::cout << "first 'needle' found at: " << found << '\n';
    }

    return 0;
}

Result:

first 'needle' found at: 14.

Remove the onchange event from the HTML Markup and bind it in your document ready event

<select  name="a[b]" >
     <option value='Choice 1'>Choice 1</option>
     <option value='Choice 2'>Choice 2</option>
</select>?

and Script

$(function(){    
    $("select[name='a[b]']").change(function(){
       alert($(this).val());        
    }); 
});

As it has been outlined here, because Google is sending an "X-Frame-Options: SAMEORIGIN" response header you cannot simply set the src to "http://www.google.com" in a iframe.

If you want to embed Google into an iframe you can do what sudopeople suggested in a comment above and use a Google custom search link like the following. This worked great for me (left 'q=' blank to start with blank search).

<iframe id="if1" width="100%" height="254" style="visibility:visible" src="http://www.google.com/custom?q=&btnG=Search"></iframe>

EDIT:

This answer no longer works. For information, and instructions on how to replace an iframe search with a google custom search element check out: https://support.google.com/customsearch/answer/2641279

The first one matches a single whitespace, whereas the second one matches one or many whitespaces. They're the so-called regular expression quantifiers, and they perform matches like this (taken from the documentation):

Greedy quantifiers
X?  X, once or not at all
X*  X, zero or more times
X+  X, one or more times
X{n}    X, exactly n times
X{n,}   X, at least n times
X{n,m}  X, at least n but not more than m times

Reluctant quantifiers
X?? X, once or not at all
X*? X, zero or more times
X+? X, one or more times
X{n}?   X, exactly n times
X{n,}?  X, at least n times
X{n,m}? X, at least n but not more than m times

Possessive quantifiers
X?+ X, once or not at all
X*+ X, zero or more times
X++ X, one or more times
X{n}+   X, exactly n times
X{n,}+  X, at least n times
X{n,m}+ X, at least n but not more than m times

Right click on the project in solution-explorer and click "clean".

Now run F5

Make sure the code is as below:

Console.WriteLine("TEST");
Console.ReadLine();

Well in general:

List<String> names = new ArrayList<String>();
names.add("john");
names.add("ann");

String[] namesArr = new String[names.size()];
for (int i = 0; i < names.size(); i++) {
    namesArr[i] = names.get(i);  
}

Or better yet, using built in:

List<String> names = new ArrayList<String>();
String[] namesArr = names.toArray(new String[names.size()]);

I had a similar scenario, and I thought that something like

str.replaceAll("\[|\]", "");

looked cleaner. Of course, if your token might have brackets in it, that wouldn't work.

This is a step-by-step procedure to get pkg-config working on Windows, based on my experience, using the info from Oliver Zendel's comment.

I assume here that MinGW was installed to C:\MinGW. There were multiple versions of the packages available, and in each case I just downloaded the latest version.

1. go to http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
2. download the file pkg-config_0.26-1_win32.zip
3. extract the file bin/pkg-config.exe to C:\MinGW\bin
4. download the file gettext-runtime_0.18.1.1-2_win32.zip
5. extract the file bin/intl.dll to C:\MinGW\bin
6. go to http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28
7. download the file glib_2.28.8-1_win32.zip
8. extract the file bin/libglib-2.0-0.dll to C:\MinGW\bin

Now CMake will be able to use pkg-config if it is configured to use MinGW.

There are two differences between static inner and non static inner classes.

1. In case of declaring member fields and methods, non static inner class cannot have static fields and methods. But, in case of static inner class, can have static and non static fields and method.

2. The instance of non static inner class is created with the reference of object of outer class, in which it has defined, this means it has enclosing instance. But the instance of static inner class is created without the reference of Outer class, which means it does not have enclosing instance.

See this example

class A
{
    class B
    {
        // static int x; not allowed here
    }

    static class C
    {
        static int x; // allowed here
    }
}

class Test
{
    public static void main(String… str)
    {
        A a = new A();

        // Non-Static Inner Class
        // Requires enclosing instance
        A.B obj1 = a.new B(); 

        // Static Inner Class
        // No need for reference of object to the outer class
        A.C obj2 = new A.C(); 
    }
}

On GCC it may look like this:

const char* WeekEnumNames [] = {
    [Mon] = "Mon",
    [Tue] = "Tue",
    [Wed] = "Wed",
    [Thu] = "Thu",
    [Fri] = "Fri",
    [Sat] = "Sat",
    [Sun] = "Sun",
};

For Sourcetree users: If you want to ignore a specific folder, just select a file from this folder, right-click on it and do "Ignore...". You will have a pop-up menu where you can ignore "Ignore everything beneath: <YOUR UNWANTED FOLDER>"

If you have the "Ignore" option greyed out, you have to select the "Stop Tracking" option. After that the file will be added to Staged files with a minus sign on red background icon and the file's icon in Unstaged files list will change to a question sign on a violet background. Now in Unstaged files list, the "Ignore" option is enabled again. Just do as described above.

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

You can use issubclass() like this assert issubclass(suit, Suit).

instead of using

session.delete(object)

use

getHibernateTemplate().delete(object)

In both place for select query and also for delete use getHibernateTemplate()

In select query you have to use DetachedCriteria or Criteria

Example for select query

List<foo> fooList = new ArrayList<foo>();
DetachedCriteria queryCriteria = DetachedCriteria.forClass(foo.class);
queryCriteria.add(Restrictions.eq("Column_name",restriction));
fooList = getHibernateTemplate().findByCriteria(queryCriteria);

In hibernate avoid use of session,here I am not sure but problem occurs just because of session use

You will have the duplicate values for name and price here. And ids are duplicate in the drinks_photos table.There is no way you can avoid them.Also what exactly you want the output ?

The complete code with version checking.

 if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) {

    // do stuff for iOS 7 and newer
    [self.navigationController.navigationBar setBarTintColor:[UIColor yellowColor]];
}
else {

    // do stuff for older versions than iOS 7
    [self.navigationController.navigationBar setTintColor:[UIColor yellowColor]];
}

You need make sure to start the session at the top of every PHP file where you want to use the $_SESSION superglobal. Like this:

<?php
  session_start();
  echo $_SESSION['youritem'];
?>

You forgot the Session HELPER.

Although Other Answers work well, i want to give you alternate short version which i use very often:

Customer::select('customers.*')
        ->leftJoin('orders', 'customers.id', '=', 'orders.customer_id')
        ->whereNull('orders.customer_id')->first();

And as in laravel version 5.3 added one more feature which will make your work even simpler look below for example:

Customer::doesntHave('orders')->get();

if ($select.find('option[value=' + val + ']').length) {...}

This works for me:

put this in your markup:

<div class="panel panel-default" [ngStyle]="{'background-image': getUrl()}">

then in component:

getUrl()
{
  return "url('http://estringsoftware.com/wp-content/uploads/2017/07/estring-header-lowsat.jpg')";
}

I don't think this is possible using PostgreSQL alone in the most general case. When you install PostgreSQL, you pick a time zone. I'm pretty sure the default is to use the operating system's timezone. That will usually be reflected in postgresql.conf as the value of the parameter "timezone". But the value ends up as "localtime". You can see this setting with the SQL statement.

show timezone;

But if you change the timezone in postgresql.conf to something like "Europe/Berlin", then show timezone; will return that value instead of "localtime".

So I think your solution will involve setting "timezone" in postgresql.conf to an explicit value rather than the default "localtime".

To populate a List of String, you need not use custom row mapper. Implement it using queryForList.

List<String>data=jdbcTemplate.queryForList(query,String.class)

To convert a string to lower case in Python, use something like this.

list.append(sentence.lower())

I found this in the first result after searching for "python upper to lower case".

Answer seems to be a little old, What I did was to use this mapper to convert a MAP

      ObjectMapper mapper = new ObjectMapper().configure(SerializationConfig.Feature.WRITE_NULL_MAP_VALUES, false);

a simple Map:

          Map<String, Object> user = new HashMap<String,Object>();
            user.put( "id",  teklif.getAccount().getId() );
            user.put( "fname", teklif.getAccount().getFname());
            user.put( "lname", teklif.getAccount().getLname());
            user.put( "email", teklif.getAccount().getEmail());
            user.put( "test", null);

Use it like this for example:

      String json = mapper.writeValueAsString(user);

In Matrix terms, the number of elements always has to equal the product of the number of rows and columns. In this particular case, the condition is not matching.

This should do the trick for you.

For one word:

if (!string.Contains("One"))

For two words:

if (!(string.Contains("One") && string.Contains("Two")))

try this (if your server is Linux):

$command="/sbin/ifconfig eth0 | grep 'inet addr:' | cut -d: -f2 | awk '{ print $1}'";
$localIP = exec ($command);
echo $localIP;

Just add required to file or url

<div style={
   {
      backgroundImage: `url(${require("./path_local")})`,      
   }
}
>

Or set in css base64 image like

div {
  background:
    url('data:image/gif;base64,R0lGODlhZQBhAPcAACQgDxMFABsHABYJABsLA')
    no-repeat
    left center;
}

You can use https://www.base64-image.de/ for convert

Note: "schtasks" (see the other, accepted response) has replaced "at". However, "at" may be of use if the situation calls for compatibility with older versions of Windows that don't have schtasks.

Command-line help for "at":

C:\>at /?
The AT command schedules commands and programs to run on a computer at
a specified time and date. The Schedule service must be running to use
the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
    [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\\computername     Specifies a remote computer. Commands are scheduled on the
                   local computer if this parameter is omitted.
id                 Is an identification number assigned to a scheduled
                   command.
/delete            Cancels a scheduled command. If id is omitted, all the
                   scheduled commands on the computer are canceled.
/yes               Used with cancel all jobs command when no further
                   confirmation is desired.
time               Specifies the time when command is to run.
/interactive       Allows the job to interact with the desktop of the user
                   who is logged on at the time the job runs.
/every:date[,...]  Runs the command on each specified day(s) of the week or
                   month. If date is omitted, the current day of the month
                   is assumed.
/next:date[,...]   Runs the specified command on the next occurrence of the
                   day (for example, next Thursday).  If date is omitted, the
                   current day of the month is assumed.
"command"          Is the Windows NT command, or batch program to be run.

If it is possible to change the sequence of the lines you could do:

1. sort line with Edit -> Line Operations -> Sort Lines Lexicographically ascending
2. do a Find / Replace:
   • Find What: ^(.*\r?\n)\1+
   • Replace with: (Nothing, leave empty)
   • Check Regular Expression in the lower left
   • Click Replace All

How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n) and captures the line in \1 then it continues and tries to find \1 one or more times (+) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.

The \r?\n should deal nicely with Windows and Unix lineendings.

Thanks for the replies.

I tried the first approach, but nothing changed. Then, I tried to log the results. I just drilled down level by level, until I finally got to where the data was being displayed.

After a while I found the problem: When I was sending the response, I was converting it to a string via .toString().

I fixed that and now it works brilliantly. Sorry for the false alarm.

The reason it is only a suggestion is that you could quite easily write a print function that ignored the options value. The built-in printing and formatting functions do use the options value as a default.

As to the second question, since R uses finite precision arithmetic, your answers aren't accurate beyond 15 or 16 decimal places, so in general, more aren't required. The gmp and rcdd packages deal with multiple precision arithmetic (via an interace to the gmp library), but this is mostly related to big integers rather than more decimal places for your doubles.

Mathematica or Maple will allow you to give as many decimal places as your heart desires.

EDIT:
It might be useful to think about the difference between decimal places and significant figures. If you are doing statistical tests that rely on differences beyond the 15th significant figure, then your analysis is almost certainly junk.

On the other hand, if you are just dealing with very small numbers, that is less of a problem, since R can handle number as small as .Machine$double.xmin (usually 2e-308).

Compare these two analyses.

x1 <- rnorm(50, 1, 1e-15)
y1 <- rnorm(50, 1 + 1e-15, 1e-15)
t.test(x1, y1)  #Should throw an error

x2 <- rnorm(50, 0, 1e-15)
y2 <- rnorm(50, 1e-15, 1e-15)
t.test(x2, y2)  #ok

In the first case, differences between numbers only occur after many significant figures, so the data are "nearly constant". In the second case, Although the size of the differences between numbers are the same, compared to the magnitude of the numbers themselves they are large.

As mentioned by e3bo, you can use multiple-precision floating point numbers using the Rmpfr package.

mpfr("3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825")

These are slower and more memory intensive to use than regular (double precision) numeric vectors, but can be useful if you have a poorly conditioned problem or unstable algorithm.

To remove node you can try this solution it helped me.

var rslt = (nodee=document.getElementById(id)).parentNode.removeChild(nodee);

Your code doesn't get the UTF-8 into memory as you read it back into a string again, so its no longer in UTF-8, but back in UTF-16 (though ideally its best to consider strings at a higher level than any encoding, except when forced to do so).

To get the actual UTF-8 octets you could use:

var serializer = new XmlSerializer(typeof(SomeSerializableObject));

var memoryStream = new MemoryStream();
var streamWriter = new StreamWriter(memoryStream, System.Text.Encoding.UTF8);

serializer.Serialize(streamWriter, entry);

byte[] utf8EncodedXml = memoryStream.ToArray();

I've left out the same disposal you've left. I slightly favour the following (with normal disposal left in):

var serializer = new XmlSerializer(typeof(SomeSerializableObject));
using(var memStm = new MemoryStream())
using(var  xw = XmlWriter.Create(memStm))
{
  serializer.Serialize(xw, entry);
  var utf8 = memStm.ToArray();
}

Which is much the same amount of complexity, but does show that at every stage there is a reasonable choice to do something else, the most pressing of which is to serialise to somewhere other than to memory, such as to a file, TCP/IP stream, database, etc. All in all, it's not really that verbose.

I also had a task like this and when I was done, using the above method, a new method occured to me: Why don't you do this:

1. Reverse the string ("string one" becomes "eno gnirts").
2. Use the good old Find (which is hardcoded for left-to-right).
3. Reverse it into readable string again.

How does this sound?

I had the same problem, and found the answer. If you use node.js with express, you need to give it its own function in order for the js file to be reached. For example:

const script = path.join(__dirname, 'script.js');
const server = express().get('/', (req, res) => res.sendFile(script))

You can use ContainsKey:

if (dict.ContainsKey(key)) { ... }

or TryGetValue:

dict.TryGetValue(key, out value);

Update: according to a comment the actual class here is not an IDictionary but a PhysicalAddressDictionary, so the methods are Contains and TryGetValue but they work in the same way.

Example usage:

PhysicalAddressEntry entry;
PhysicalAddressKey key = c.PhysicalAddresses[PhysicalAddressKey.Home].Street;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    row["HomeStreet"] = entry;
}

Update 2: here is the working code (compiled by question asker)

PhysicalAddressEntry entry;
PhysicalAddressKey key = PhysicalAddressKey.Home;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    if (entry.Street != null)
    {
        row["HomeStreet"] = entry.Street.ToString();
    }
}

...with the inner conditional repeated as necessary for each key required. The TryGetValue is only done once per PhysicalAddressKey (Home, Work, etc).

Atomic property can be accessed by only one thread at a time. It is thread safe. Default is atomic .Please note that there is no keyword atomic

Nonatomic means multiple thread can access the item .It is thread unsafe

So one should be very careful while using atomic .As it affect the performance of your code

To search the whole computer:

gdr -PSProvider 'FileSystem' | %{ ls -r $_.root} 2>$null | where { $_.name -eq "httpd.exe" }

from datetime import datetime as dt
dt.utcnow().strftime("%s")

Output:

1544524990

You can easily debug such things when you go through the generated CSS. In this case the pseudo-selector after conversion has to be attached to the class. Which is not the case. Use "&".

http://sass-lang.com/documentation/file.SASS_REFERENCE.html#parent-selector

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

The trick is a second .box-inner inside, which is larger in width than the original .box, and the box-shadow is applied to that.

Then, added more padding to the .text to make up for the added width.

This is how the logic looks:

And here's how it's done in CSS:

Use max width for .inner-box to not cause .box to get wider, and overflow to make sure the remaining is clipped:

.box {
    max-width: 100% !important;
    overflow: hidden;
}

110% is wider than the parent which is 100% in a child's context (should be the same when the parent .box has a fixed width, for example). Negative margins make up for the width and cause the element to be centered (instead of only the right part hiding):

.box-inner {
    width: 110%;
    margin-left:-5%;
    margin-right: -5%;
    -webkit-box-shadow: inset 0px 5px 10px 1px #000000;
    box-shadow: inset 0px 5px 10px 1px #000000;
}

And add some padding on the X axis to make up for the wider .inner-box:

.text {
    padding: 20px 40px;
}

Here's a working Fiddle.

If you inspect the Fiddle, you'll see:

var consolidatedChildren =
    from c in children
    group c by new
    {
        c.School,
        c.Friend,
        c.FavoriteColor,
    } into gcs
    select new ConsolidatedChild()
    {
        School = gcs.Key.School,
        Friend = gcs.Key.Friend,
        FavoriteColor = gcs.Key.FavoriteColor,
        Children = gcs.ToList(),
    };

var consolidatedChildren =
    children
        .GroupBy(c => new
        {
            c.School,
            c.Friend,
            c.FavoriteColor,
        })
        .Select(gcs => new ConsolidatedChild()
        {
            School = gcs.Key.School,
            Friend = gcs.Key.Friend,
            FavoriteColor = gcs.Key.FavoriteColor,
            Children = gcs.ToList(),
        });

No real need for the JSON.NET package. You could use JavaScriptSerializer. The Serialize method will turn a managed type instance into a JSON string.

var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(instanceOfThing);

As with most things, "it depends". But to me, your practice is not bad and is not going against the HTTP spec per se. However, let's clear some things up.

First, URI's should be opaque. Even if they're not opaque to people, they are opaque to machines. In other words, the difference between http://mywebsite/api/user/13, http://mywebsite/restapi/user/13 is the same as the difference between http://mywebsite/api/user/13 and http://mywebsite/api/user/14 i.e. not the same is not the same period. So a 404 would be completely appropriate for http://mywebsite/api/user/14 (if there is no such user) but not necessarily the only appropriate response.

You could also return an empty 200 response or more explicitly a 204 (No Content) response. This would convey something else to the client. It would imply that the resource identified by http://mywebsite/api/user/14 has no content or is essentially nothing. It does mean that there is such a resource. However, it does not necessarily mean that you are claiming there is some user persisted in a data store with id 14. That's your private concern, not the concern of the client making the request. So, if it makes sense to model your resources that way, go ahead.

There are some security implications to giving your clients information that would make it easier for them to guess legitimate URI's. Returning a 200 on misses instead of a 404 may give the client a clue that at least the http://mywebsite/api/user part is correct. A malicious client could just keep trying different integers. But to me, a malicious client would be able to guess the http://mywebsite/api/user part anyway. A better remedy would be to use UUID's. i.e. http://mywebsite/api/user/3dd5b770-79ea-11e1-b0c4-0800200c9a66 is better than http://mywebsite/api/user/14. Doing that, you could use your technique of returning 200's without giving much away.

putting a background of @android:drawable/dialog_holo_light_frame, gives shadow but you can't change background color nor border style, so it's better to benefit from the shadow of it, while still be able to put a background via layer-list

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!--the shadow comes from here-->
    <item
        android:bottom="0dp"
        android:drawable="@android:drawable/dialog_holo_light_frame"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp">

    </item>

    <item
        android:bottom="0dp"
        android:left="0dp"
        android:right="0dp"
        android:top="0dp">
        <!--whatever you want in the background, here i preferred solid white -->
        <shape android:shape="rectangle">
            <solid android:color="@android:color/white" />

        </shape>
    </item>
</layer-list>

save it in the drawable folder under say shadow.xml

to assign it to a view, in the xml layout file set the background of it

android:background="@drawable/shadow"

you can search this file : resetroot.bat

just double click it so that your root accout will be reset and all the privileges are turned into YES

From the DevTools console, you can run:

document.getElementsByTagName("head")[0].innerHTML += '<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"><\/script>';

Check the available jQuery version at https://code.jquery.com/jquery/.

To check whether it's loaded, see: Checking if jquery is loaded using Javascript.

In laravel 5.1,

 <link rel="stylesheet" href="{{URL::asset('assets/css/bootstrap.min.css')}}">
 <script type="text/javascript" src="{{URL::asset('assets/js/jquery.min.js')}}"></script>

Where assets folder location is inside public folder

The only reason I can think of is you are adding it as string 'now()', not function call now().
Or whatever else typo.

SELECT NOW();

to see if it returns correct value?

import java.util.ArrayList;
public class numbers {
   private int number1 = 50;
   private int number2 = 100;
   private List<Integer> list;

   public numbers() {
       list = new ArrayList<Integer>();
       list.add(number1);
       list.add(number2);
   }

   public List<Integer> getList() {
       return list;
   }
}

And the test class:

import java.util.ArrayList;
public class test {
   private numbers number;

   //example
   public test() {
     number = new numbers();
     List<Integer> list = number.getList();
     //hurray !
   }
}

The .join() method has a parameter for the separator string. If you want it to be empty instead of the default comma, use

arr.join("");

I have a similar problem, I tested adding code and found some interesting results. With this code I add, I can deduce that depending on the "provider" to use, the firm can be different? (because the data included in the encryption is not always equal in all providers).

Results of my test.

In PostgreSQL 9.5 and newer you can use INSERT ... ON CONFLICT UPDATE.

See the documentation.

A MySQL INSERT ... ON DUPLICATE KEY UPDATE can be directly rephrased to a ON CONFLICT UPDATE. Neither is SQL-standard syntax, they're both database-specific extensions. There are good reasons MERGE wasn't used for this, a new syntax wasn't created just for fun. (MySQL's syntax also has issues that mean it wasn't adopted directly).

e.g. given setup:

CREATE TABLE tablename (a integer primary key, b integer, c integer);
INSERT INTO tablename (a, b, c) values (1, 2, 3);

the MySQL query:

INSERT INTO tablename (a,b,c) VALUES (1,2,3)
  ON DUPLICATE KEY UPDATE c=c+1;

becomes:

INSERT INTO tablename (a, b, c) values (1, 2, 10)
ON CONFLICT (a) DO UPDATE SET c = tablename.c + 1;

Differences:

• You must specify the column name (or unique constraint name) to use for the uniqueness check. That's the ON CONFLICT (columnname) DO

• The keyword SET must be used, as if this was a normal UPDATE statement

It has some nice features too:

• You can have a WHERE clause on your UPDATE (letting you effectively turn ON CONFLICT UPDATE into ON CONFLICT IGNORE for certain values)

• The proposed-for-insertion values are available as the row-variable EXCLUDED, which has the same structure as the target table. You can get the original values in the table by using the table name. So in this case EXCLUDED.c will be 10 (because that's what we tried to insert) and "table".c will be 3 because that's the current value in the table. You can use either or both in the SET expressions and WHERE clause.

For background on upsert see How to UPSERT (MERGE, INSERT ... ON DUPLICATE UPDATE) in PostgreSQL?

To center align both vertically and horizontally:

#parentDiv{
    display:table;
    text-align:center;
}

#child {
     display:table-cell;
     vertical-align:middle;
}

Good lord no. Sometimes there is a possibility that something can occur in the loop that satisfies the overall requirement, without satisfying the logical loop condition. In that case, break is used, to stop you cycling around a loop pointlessly.

Example

String item;

for(int x = 0; x < 10; x++)
{
    // Linear search.
    if(array[x].equals("Item I am looking for"))
    {
       //you've found the item. Let's stop.
       item = array[x];
       break; 
    }
}

What makes more sense in this example. Continue looping to 10 every time, even after you've found it, or loop until you find the item and stop? Or to put it into real world terms; when you find your keys, do you keep looking?

Edit in response to comment

Why not set x to 11 to break the loop? It's pointless. We've got break! Unless your code is making the assumption that x is definitely larger than 10 later on (and it probably shouldn't be) then you're fine just using break.

Edit for the sake of completeness

There are definitely other ways to simulate break. For example, adding extra logic to your termination condition in your loop. Saying that it is either loop pointlessly or use break isn't fair. As pointed out, a while loop can often achieve similar functionality. For example, following the above example..

while(x < 10 && item == null)
{
    if(array[x].equals("Item I am looking for"))
    {
        item = array[x];
    }

    x++;
}

Using break simply means you can achieve this functionality with a for loop. It also means you don't have to keep adding in conditions into your termination logic, whenever you want the loop to behave differently. For example.

for(int x = 0; x < 10; x++)
{
   if(array[x].equals("Something that will make me want to cancel"))
   {
       break;
   }
   else if(array[x].equals("Something else that will make me want to cancel"))
   {
       break;
   }
   else if(array[x].equals("This is what I want"))
   {
       item = array[x];
   }
}

Rather than a while loop with a termination condition that looks like this:

while(x < 10 && !array[x].equals("Something that will make me want to cancel") && 
                !array[x].equals("Something else that will make me want to cancel"))

If your string is in ISO 8601 format, you can also use from_iso8601_timestamp

It's actually pretty easy. (If you're using Angular 2+ anyway.)

Simply add

declare var myGlobalVarName;

Somewhere in the top of your component file (such as after the "import" statements), and you'll be able to access "myGlobalVarName" anywhere inside your component.

Table A 
+--------+-----------+
| A-num  | text      | 
|    1   |           |
|    2   |           |
|    3   |           |
|    4   |           |
|    5   |           |
+--------+-----------+

Table B
+------+------+--------------+
| B-num|  date        |  A-num | 
|  22  |  01.08.2003  |     2  |
|  23  |  02.08.2003  |     2  | 
|  24  |  03.08.2003  |     1  |
|  25  |  04.08.2003  |     4  |
|  26  |  05.03.2003  |     4  |

I will update field text in table A with

UPDATE `Table A`,`Table B`
SET `Table A`.`text`=concat_ws('',`Table A`.`text`,`Table B`.`B-num`," from                                           
",`Table B`.`date`,'/')
WHERE `Table A`.`A-num` = `Table B`.`A-num`

and come to this result:

Table A 
+--------+------------------------+
| A-num  | text                   | 
|    1   |  24 from 03 08 2003 /  |
|    2   |  22 from 01 08 2003 /  |       
|    3   |                        |
|    4   |  25 from 04 08 2003 /  |
|    5   |                        |
--------+-------------------------+

where only one field from Table B is accepted, but I will come to this result:

Table A 
+--------+--------------------------------------------+
| A-num  | text                                       | 
|    1   |  24 from 03 08 2003                        |
|    2   |  22 from 01 08 2003 / 23 from 02 08 2003 / |       
|    3   |                                            |
|    4   |  25 from 04 08 2003 / 26 from 05 03 2003 / |
|    5   |                                            |
+--------+--------------------------------------------+

var filtered = Directory.GetFiles(path)
    .Where(file => file.EndsWith("aspx", StringComparison.InvariantCultureIgnoreCase) || file.EndsWith("ascx", StringComparison.InvariantCultureIgnoreCase))
    .ToList();

If you are running on linux:

dpkg -l | grep cuda

Do not use passwords. Use peer authentication instead:

postgres://myuser@%2Fvar%2Frun%2Fpostgresql/mydb

You need to use event delegation because those buttons don't exist on load:

http://jsfiddle.net/isherwood/Z7fG7/1/

 $(document).on('click', 'button.removebutton', function () { // <-- changes
     alert("aa");
     $(this).closest('tr').remove();
     return false;
 });

First, you can use sql command show global variables like 'innodb_buffer%'; to check the buffer size.

Solution is find your my.cnf file and add,

[mysqld]_x000D_
innodb_buffer_pool_size=1G # depends on your data and machine

DO NOT forget to add [mysqld], otherwise, it won't work.

In my case, ubuntu 16.04, my.cnf is located under the folder /etc/mysql/.

I am using Oracle SQL Developer,

In this tool, I had to enable DBMS output to view the results printed by dbms_output.put_line

You can find this option in the result pane where other query results are displayed. so, in the result pane, I have 7 tabs. 1st tab named as Results, next one is Script Output and so on. Out of this you can find a tab named as "DBMS Output" select this tab, then the 1st icon (looks like a dialogue icon) is Enable DBMS Output. Click this icon. Then you execute the PL/SQL, then select "DBMS Output tab, you should be able to see the results there.

You can just try to establish a TCP connection to a remote host:

public boolean hostAvailable(String host, int port) {
  try (Socket socket = new Socket()) {
    socket.connect(new InetSocketAddress(host, port), 2000);
    return true;
  } catch (IOException e) {
    // Either we have a timeout or unreachable host or failed DNS lookup
    System.out.println(e);
    return false;
  }
}

Then:

boolean online = hostAvailable("www.google.com", 80);

These numbers come from the IEEE-754 standard, which defines the standard representation of floating point numbers. Wikipedia article at the link explains how to arrive at these ranges knowing the number of bits used for the signs, mantissa, and the exponent.

I think you need quotes around your {$row['null_field']}, so '{$row['null_field']}'

If you don't have the quotes, you'll occasionally end up with an insert statement that looks like this: insert into table2 (f1, f2) values ('val1',) which is a syntax error.

If that is a numeric field, you will have to do some testing above it, and if there is no value in null_field, explicitly set it to null..

I don't know if this is good practice or not, but casting a Context object to an Activity object compiles fine.

Try this: ((Activity) mContext).startActivity(...)

You need to set a -D system property called java.library.path that points at the directory containing the sqljdbc_auth.dll.

I can run on my device at last, just I enabled the "USB debugging" and "Allow mock location" options from the Debug Menu of my device.

Open https://www.google-analytics.com/analytics.js file in a new tab, copy all the code.

Now create a folder in your web directory, rename it to google-analytics.

Create a text file in the same folder and paste all the code you copied above.

Rename the file ga-local.js

Now change the URL to call your locally hosted Analytics Script file in your Google Analytics Code. It will look something like this i.e. https://domain.xyz/google-analytics/ga.js

Finally, place your NEW google analytics code into the footer of your webpage.

You are good to go. Now check your website of Google PageSpeed Insights. It will not show the warning for Leverage Browser Caching Google Analytics. And the only problem with this solution is, to regularly update the Analytics Script manually.

C# equivalent of your code is

  class Imagedata : PDFStreamEngine
  {
     // C# uses "base" keyword whenever Java uses "super" 
     // so instead of super(...) in Java we should call its C# equivalent (base):
     public Imagedata()
       : base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true)) 
     { }

     // Java methods are virtual by default, when C# methods aren't.
     // So we should be sure that processOperator method in base class 
     // (that is PDFStreamEngine)
     // declared as "virtual"
     protected override void processOperator(PDFOperator operations, List arguments)
     {
        base.processOperator(operations, arguments);
     }
  }

In summary, the most reliable way to have MiniDLNA rescan all media files is by issuing the following set of commands:

$ sudo minidlnad -R
$ sudo service minidlna restart

Client-side script to rescan server

However, every so often MiniDLNA will be running on a server. Here is a client-side script to request a rescan on such a server:

#!/usr/bin/env bash
ssh -t server.on.lan 'sudo minidlnad -R && sudo service minidlna restart'

I had the same issue but managed to resolve it using boto3.client and list_objects_v2 with Bucket and StartAfter parameters.

s3client = boto3.client('s3')
bucket = 'my-bucket-name'
startAfter = 'firstlevelFolder/secondLevelFolder'

theobjects = s3client.list_objects_v2(Bucket=bucket, StartAfter=startAfter )
for object in theobjects['Contents']:
    print object['Key']

The output result for the code above would display the following:

firstlevelFolder/secondLevelFolder/item1
firstlevelFolder/secondLevelFolder/item2

Boto3 list_objects_v2 Documentation

In order to strip out only the directory name for secondLevelFolder I just used python method split():

s3client = boto3.client('s3')
bucket = 'my-bucket-name'
startAfter = 'firstlevelFolder/secondLevelFolder'

theobjects = s3client.list_objects_v2(Bucket=bucket, StartAfter=startAfter )
for object in theobjects['Contents']:
    direcoryName = object['Key'].encode("string_escape").split('/')
    print direcoryName[1]

The output result for the code above would display the following:

secondLevelFolder
secondLevelFolder

Python split() Documentation

If you'd like to get the directory name AND contents item name then replace the print line with the following:

print "{}/{}".format(fileName[1], fileName[2])

And the following will be output:

secondLevelFolder/item2
secondLevelFolder/item2

Hope this helps

You might want to take a look at these questions/answers ; they could give you some informations concerning your problem :

• cross domain access in iframe from child to parent
• <iframe> javascript access parent DOM across domains?
• How to access parent Iframe from javascript

To make things short : accessing iframe from another domain is not possible, for security reasons -- which explains the error message you are getting.

The Same origin policy page on wikipedia brings some informations about that security measure :

In a nutshell, the policy permits scripts running on pages originating from the same site to access each other's methods and properties with no specific restrictions — but prevents access to most methods and properties across pages on different sites.

A strict separation between content provided by unrelated sites must be maintained on client side to prevent the loss of data confidentiality or integrity.

All you need to do to get the event is the following:

console.log(angular.element(event.which));

A directive can do it, but that is not how you do it.

The trade off you are getting is that the program runs a wee bit faster. That may be a cold comfort to you during development, but it could matter a great deal once development is complete, and the program is just being run by users.

There is also dialog and the KDE version kdialog. dialog is used by slackware, so it might not be immediately available on other distributions.

Another common gotcha is thinking you can ignore the Form DragOver (or DragEnter) events. I typically use the Form's DragOver event to set the AllowedEffect, and then a specific control's DragDrop event to handle the dropped data.

You can use:

Select
     count(created_date) as counted_leads,
     created_date as count_date
from
     table
group by
     created_date

It creates a hidden input on the form for the field (from your model) that you pass it.

It is useful for fields in your Model/ViewModel that you need to persist on the page and have passed back when another call is made but shouldn't be seen by the user.

Consider the following ViewModel class:

public class ViewModel
{
    public string Value { get; set; }
    public int Id { get; set; }
}

Now you want the edit page to store the ID but have it not be seen:

<% using(Html.BeginForm() { %>
    <%= Html.HiddenFor(model.Id) %><br />
    <%= Html.TextBoxFor(model.Value) %>
<% } %>

This results in the equivalent of the following HTML:

<form name="form1">
    <input type="hidden" name="Id">2</input>
    <input type="text" name="Value" value="Some Text" />
</form>

According to JVM specification, fields and methods in a Interface can have only Public, Static, Final and Abstract. Ref from Inside Java VM

By default, all the methods in interface is abstract even tough you didn't mention it explicitly.

Interfaces are meant to give only specification. It can not contain any implementations. So To avoid implementing classes to change the specification, it is made final. Since Interface cannot be instantiated, they are made static to access the field using interface name.

I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.

HEAD: the current commit your repo is on. Most of the time HEAD points to the latest commit in your current branch, but that doesn't have to be the case. HEAD really just means "what is my repo currently pointing at".

In the event that the commit HEAD refers to is not the tip of any branch, this is called a "detached head".

master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.

origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.

HEAD is an official notion in git. HEAD always has a well-defined meaning. master and origin are common names usually used in git, but they don't have to be.

Observe if the view has the model required:

View

@model IEnumerable<WFAccess.Models.ViewModels.SiteViewModel>

<div class="row">
    <table class="table table-striped table-hover table-width-custom">
        <thead>
            <tr>
....

Controller

[HttpGet]
public ActionResult ListItems()
{
    SiteStore site = new SiteStore();
    site.GetSites();

    IEnumerable<SiteViewModel> sites =
        site.SitesList.Select(s => new SiteViewModel
        {
            Id = s.Id,
            Type = s.Type
        });

    return PartialView("_ListItems", sites);
}

In my case I Use a partial view but runs in normal views

Underline to multiple strings in a sentence.

extension UILabel {
    func underlineMyText(range1:String, range2:String) {
        if let textString = self.text {

            let str = NSString(string: textString)
            let firstRange = str.range(of: range1)
            let secRange = str.range(of: range2)
            let attributedString = NSMutableAttributedString(string: textString)
            attributedString.addAttribute(NSAttributedString.Key.underlineStyle, value: NSUnderlineStyle.single.rawValue, range: firstRange)
            attributedString.addAttribute(NSAttributedString.Key.underlineStyle, value: NSUnderlineStyle.single.rawValue, range: secRange)
            attributedText = attributedString
        }
    }
}

Use by this way.

    lbl.text = "By continuing you agree to our Terms of Service and Privacy Policy."
    lbl.underlineMyText(range1: "Terms of Service", range2: "Privacy Policy.")
