TL;DR: Avoid Number constructor, unary +; use a simple if all the time; resort to bool | 0 or 1 * bool if benchmarks in your project do better this way.

This is quite an old question, and there exist many valid answers. Something I've noticed is that all benchmarks here are irrelevant - none take into account branch prediction. Also, nowadays, JS engines don't simply interpret the code, they JIT compile it to native machine code and optimize it prior to execution. This means that, besides branch prediction, the compiler can even substitute expressions with their final value.

Now, how do these 2 factors affect the performance of, well, boolean to integer conversion? Let's find out! Before we get into the benchmarks, it is important to know what we benchmark. For the conversion, we're using the following seven conversion methods:

• Number constructor: Number(bool)
• If statement (ternary used): bool ? 1 : 0
• Unary operator +: +bool
• Bitwise OR: bool | 0
• Bitwise AND: bool & 1
• Bitwise double NOT: ~~bool
• Number multiplication: bool * 1

"Conversion" means converting false to 0 and true to 1¹. Each conversion method is ran 100000 times, measuring operations/millisecond. In the following tables, conversion methods will be grouped to their results accordingly. The results are from my machine, which features an AMD Ryzen 7 4800HS as its CPU.

The first benchmark converts the constant true:

Interesting! V8 shows some huge numbers, all of them approximately the same! Spidermonkey doesn't really shine, but we can see that the bitwise and multiplication tricks come first, and the ternary if second. What are the takeaways? Chrome browsers manage to replace our conversions with simply the value 1. This optimization will take place where we can mentally replace the boolean to a constant value.

That above isn't a situation we'll ever encounter in real projects. So let's change our variables: the bool is now Math.random() < 0.5. This yields a 50% chance of true, 50% of false. Do our results change? Let's run this benchmark to see.

The results are more consistent now. We see similar numbers for ternary if, bitwise, and multiplication methods, but the Number constructor and unary + perform better on V8. We can presume from the numbers that V8 replaces them with whatever instructions it's using for the bitwise tricks, but in Spidermonkey those functions do all the work.

We haven't still tackled one factor we mentioned above: branch prediction. Let's change, in this benchmark, our boolean variable to Math.random() < 0.01, which means 1% true, 99% false.

Unexpected? Expected? I'd say the latter, because in this case branch prediction was successful in almost all cases, given the tiny difference between the ternary if and bitwise hacks. All other results are the same, not much else to say here.

This endeavour brings us back to the original question: how to convert bool to int in Javascript? Here are my suggestions:

• Avoid Number(bool) and +bool. These 2 methods do a lot of work under the hood, and even though Chrome managed to optimize them in our benchmarks, Firefox did not, and there might be some situations where these optimizations won't be done by the compiler. Besides that, not everyone's on Chrome! I still have to put up with that, don't you?...
• Use if statements, in general. Don't get smart - the browser will do better, usually, and usually means most of the situations. They are the most readable and clear out of all the methods here. While we're at readability, maybe use if (bool) instead of that ugly ternary! I wish Javascript had what Rust or Python have...
• Use the rest when it's truly necessary. Maybe benchmarks in your project perform sub-standard, and you found that a nasty if causes bad performance - if that's the case, feel free to get into branchless programming! But don't go too deep in that rabbit hole, nobody will benefit from things like -1 * (a < b) + 1 * (a > b), believe me.

I will be forever grateful to you for reading until the end - this is my first longer, significant StackOverflow answer and it means the world to me if it's been helpful and insightful. If you find any errors, feel free to correct me!

1. Defined the conversion because it's not truly clear what boolean to integer means. For example, Go does not support this conversion at all.

Please explain why same ng-model is used? And what value is passed through ng- model and how it is passed? To be more specific, if I use console.log(color) what would be the output?

No, since the other option is modifying the Zend engine, and one would be hard-pressed to call that a "better way".

Edit:

If you really wanted to, you could use an array:

$boolarray = Array(false => 'false', true => 'true');
echo $boolarray[false];

When you say

(a['x']==1) and (a['y']==10)

You are implicitly asking Python to convert (a['x']==1) and (a['y']==10) to boolean values.

NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a boolean value -- in other words, they raise

ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all().

when used as a boolean value. That's because its unclear when it should be True or False. Some users might assume they are True if they have non-zero length, like a Python list. Others might desire for it to be True only if all its elements are True. Others might want it to be True if any of its elements are True.

Because there are so many conflicting expectations, the designers of NumPy and Pandas refuse to guess, and instead raise a ValueError.

Instead, you must be explicit, by calling the empty(), all() or any() method to indicate which behavior you desire.

In this case, however, it looks like you do not want boolean evaluation, you want element-wise logical-and. That is what the & binary operator performs:

(a['x']==1) & (a['y']==10)

returns a boolean array.

By the way, as alexpmil notes, the parentheses are mandatory since & has a higher operator precedence than ==. Without the parentheses, a['x']==1 & a['y']==10 would be evaluated as a['x'] == (1 & a['y']) == 10 which would in turn be equivalent to the chained comparison (a['x'] == (1 & a['y'])) and ((1 & a['y']) == 10). That is an expression of the form Series and Series. The use of and with two Series would again trigger the same ValueError as above. That's why the parentheses are mandatory.

That question solved a quite similar question for me and I thought I should share :

In raw python you can use sum() to count True values in a list :

>>> sum([True,True,True,False,False])
3

But this won't work :

>>> sum([[False, False, True], [True, False, True]])
TypeError...

import org.apache.commons.lang3.BooleanUtils;
boolean x = true;   
int y= BooleanUtils.toInteger(x);

Readability should be the goal. Someone who reads the code must understand your intent immediately. So here is my solution.

int howManyBooleansAreTrue =
      (a ? 1 : 0)
    + (b ? 1 : 0)
    + (c ? 1 : 0);

return howManyBooleansAreTrue >= 2;

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

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

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

if (verifyPwd())  {
  // do_task
}

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

boolean success = true;

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

// Do some more critical things.

return success;

Charles Bailey's answer is correct. The exact wording from the C++ standard is (§4.7/4): "If the source type is bool, the value false is converted to zero and the value true is converted to one."

Edit: I see he's added the reference as well -- I'll delete this shortly, if I don't get distracted and forget...

Edit2: Then again, it is probably worth noting that while the Boolean values themselves always convert to zero or one, a number of functions (especially from the C standard library) return values that are "basically Boolean", but represented as ints that are normally only required to be zero to indicate false or non-zero to indicate true. For example, the is* functions in <ctype.h> only require zero or non-zero, not necessarily zero or one.

If you cast that to bool, zero will convert to false, and non-zero to true (as you'd expect).

I read that Java reserves one byte for a boolean datatype, but it uses only one bit. However, the documentation says that "its "size" isn't something that's precisely defined". See here.

Oracle itself uses Y/N for Boolean values. For completeness it should be noted that pl/sql has a boolean type, it is only tables that do not.

If you are using the field to indicate whether the record needs to be processed or not you might consider using Y and NULL as the values. This makes for a very small (read fast) index that takes very little space.

For MySQL 5.0.3 and higher, you can use BIT. The manual says:

As of MySQL 5.0.3, the BIT data type is used to store bit-field values. A type of BIT(M) enables storage of M-bit values. M can range from 1 to 64.

Otherwise, according to the MySQL manual you can use BOOL or BOOLEAN, which are at the moment aliases of tinyint(1):

Bool, Boolean: These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero values are considered true.

MySQL also states that:

We intend to implement full boolean type handling, in accordance with standard SQL, in a future MySQL release.

References: http://dev.mysql.com/doc/refman/5.5/en/numeric-type-overview.html

Because booleans have two values: true or false. Note that these are not strings, but actual boolean literals.

1 and 0 are integers, and there is no reason to confuse things by making them "alternative true" and "alternative false" (or the other way round for those used to Unix exit codes?). With strong typing in Java there should only ever be exactly two primitive boolean values.

EDIT: Note that you can easily write a conversion function if you want:

public static boolean intToBool(int input)
{
   if (input < 0 || input > 1)
   {
      throw new IllegalArgumentException("input must be 0 or 1");
   }

   // Note we designate 1 as true and 0 as false though some may disagree
   return input == 1;
}

Though I wouldn't recommend this. Note how you cannot guarantee that an int variable really is 0 or 1; and there's no 100% obvious semantics of what one means true. On the other hand, a boolean variable is always either true or false and it's obvious which one means true. :-)

So instead of the conversion function, get used to using boolean variables for everything that represents a true/false concept. If you must use some kind of primitive text string (e.g. for storing in a flat file), "true" and "false" are much clearer in their meaning, and can be immediately turned into a boolean by the library method Boolean.valueOf.

The BIT datatype is generally used to store boolean values (0 for false, 1 for true).

You can change the value of a bool all you want. As for an if:

if randombool == True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool == False

but you can also use:

if not randombool:

I'll try to give the benchmark of the three most common way (also mentioned above):

for _ in range(3):
    for stmt in stmts:
        t = min(repeat(stmt, setup, number=100_000))

Unlike Java where you would declare boolean flag = True, in Python you can just declare myFlag = True

Python would interpret this as a boolean variable

In your example, You don't need to. As a standard programming practice, all variables being referred to inside some code block, say for example try{} catch(){}, and being referred to outside the block as well, you need to declare the variables outside the try block first e.g.

This is helpful when your equals method call throws some exception e.g. NullPointerException;

     boolean isMatch = false;

     try{
         isMatch = email1.equals (email2);
      }catch(NullPointerException npe){
         .....
      }
      System.out.print("Match=="+isMatch);
      if(isMatch){
        ......
      }

_Bool is a keyword in C99: it specifies a type, just like int or double.

6.5.2

2 An object declared as type _Bool is large enough to store the values 0 and 1.

I use a ternary in a printf like this:

printf("%s\n", b?"true":"false");

If you macro it :

B2S(b) ((b)?"true":"false")

then you need to make sure whatever you pass in as 'b' doesn't have any side effects. And don't forget the brackets around the 'b' as you could get compile errors.

Joking aside, if you're only expecting your input integer to be a zero or a one, you should really be checking that this is the case.

int yourInteger = whatever;
bool yourBool;
switch (yourInteger)
{
    case 0: yourBool = false; break;
    case 1: yourBool = true;  break;
    default:
        throw new InvalidOperationException("Integer value is not valid");
}

The out-of-the-box Convert won't check this; nor will yourInteger (==|!=) (0|1).

First of all, your variable "isLeapYear" is the same name as the method. That's just bad practice.

Second, you're not declaring "isLeapYear" as a variable. Java is strongly typed so you need a boolean isLeapYear; in the beginning of your method.

This call: System.out.println(boolean isLeapYear); is just wrong. There are no declarations in method calls.

Once you have declared isLeapYear to be a boolean variable, you can call System.out.println(isLeapYear);

UPDATE: I just saw it's declared as a field. So just remove the line System.out.println(boolean isLeapYear); You should understand that you can't call isLeapYear from the main() method. You cannot call a non static method from a static method with an instance. If you want to call it, you need to add

booleanfun myBoolFun = new booleanfun();
System.out.println(myBoolFun.isLeapYear);

I really suggest you use Eclipse, it will let you know of such compilation errors on the fly and its much easier to learn that way.

Using the so called f strings:

answer = True
myvar = f"the answer is {answer}"

Then if I do

print(myvar)

I will get:

the answer is True

I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.

If the IN clause is a parameter (either to SP or hot-built SQL), then this can always be done:

SELECT (SELECT COUNT(1)
          FROM product_a
         WHERE product_id IN (1, 8, 100)
       ) = (number of commas in product_id as constant)

If the IN clause is a table, then this can always be done:

SELECT (SELECT COUNT(*)
          FROM product_a
         WHERE product_id IN (SELECT Products
                                FROM #WorkTable)
       ) = (SELECT COUNT(*)
              FROM #WorkTable)

If the IN clause is complex then either spool it into a table or write it twice.

Rule of thumb: Use -a and -o inside square brackets, && and || outside.

It's important to understand the difference between shell syntax and the syntax of the [ command.

• && and || are shell operators. They are used to combine the results of two commands. Because they are shell syntax, they have special syntactical significance and cannot be used as arguments to commands.

• [ is not special syntax. It's actually a command with the name [, also known as test. Since [ is just a regular command, it uses -a and -o for its and and or operators. It can't use && and || because those are shell syntax that commands don't get to see.

But wait! Bash has a fancier test syntax in the form of [[ ]]. If you use double square brackets, you get access to things like regexes and wildcards. You can also use shell operators like &&, ||, <, and > freely inside the brackets because, unlike [, the double bracketed form is special shell syntax. Bash parses [[ itself so you can write things like [[ $foo == 5 && $bar == 6 ]].

Have your tried using the 'return' keyword?

def rps():
    return True

You must use some of the C # conversion systems:

string to boolean: True to true

string str = "True";
bool mybool = System.Convert.ToBoolean(str);

boolean to string: true to True

bool mybool = true;
string str = System.Convert.ToString(mybool);

//or

string str = mybool.ToString();

bool.Parse expects one parameter which in this case is str, even .

Convert.ToBoolean expects one parameter.

bool.TryParse expects two parameters, one entry (str) and one out (result).

If TryParse is true, then the conversion was correct, otherwise an error occurred

string str = "True";
bool MyBool = bool.Parse(str);

//Or

string str = "True";
if(bool.TryParse(str, out bool result))
{
   //Correct conversion
}
else
{
     //Incorrect, an error has occurred
}

is compares identity. A string will never be identical to a not-string.

== is equality. But a string will never be equal to either True or False.

You want neither.

path = '/bla/bla/bla'

if path:
    print "True"
else:
    print "False"

We can use enum type for this.We don't require a library. For example

           enum {false,true};

the value for false will be 0 and the value for true will be 1.

No. I don't see any advantage. Second one is more straitforward.

btw: Second style is found in every corners of JDK source.

& is a bitwise operator plus used for checking both conditions because sometimes we need to evaluate both condition. But && logical operator go to 2nd condition when first condition give true.

A boolean in C is an integer: zero for false and non-zero for true.

See also Boolean data type, section C, C++, Objective-C, AWK.

you have to use capital True and False not true and false

theBoolean = !theBoolean;

As this very useful tutorial says:

var age = 0;

// bad
var hasAge = new Boolean(age);

// good
var hasAge = Boolean(age);

// good
var hasAge = !!age;

The standard streams have a boolalpha flag that determines what gets displayed -- when it's false, they'll display as 0 and 1. When it's true, they'll display as false and true.

There's also an std::boolalpha manipulator to set the flag, so this:

#include <iostream>
#include <iomanip>

int main() {
    std::cout<<false<<"\n";
    std::cout << std::boolalpha;   
    std::cout<<false<<"\n";
    return 0;
}

...produces output like:

0
false

For what it's worth, the actual word produced when boolalpha is set to true is localized--that is, <locale> has a num_put category that handles numeric conversions, so if you imbue a stream with the right locale, it can/will print out true and false as they're represented in that locale. For example,

#include <iostream>
#include <iomanip>
#include <locale>

int main() {
    std::cout.imbue(std::locale("fr"));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

...and at least in theory (assuming your compiler/standard library accept "fr" as an identifier for "French") it might print out faux instead of false. I should add, however, that real support for this is uneven at best--even the Dinkumware/Microsoft library (usually quite good in this respect) prints false for every language I've checked.

The names that get used are defined in a numpunct facet though, so if you really want them to print out correctly for particular language, you can create a numpunct facet to do that. For example, one that (I believe) is at least reasonably accurate for French would look like this:

#include <array>
#include <string>
#include <locale>
#include <ios>
#include <iostream>

class my_fr : public std::numpunct< char > {
protected:
    char do_decimal_point() const { return ','; }
    char do_thousands_sep() const { return '.'; }
    std::string do_grouping() const { return "\3"; }
    std::string do_truename() const { return "vrai";  }
    std::string do_falsename() const { return "faux"; }
};

int main() {
    std::cout.imbue(std::locale(std::locale(), new my_fr));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

And the result is (as you'd probably expect):

0
faux

As mentioned above BOOL could be an unsigned char type depending on your architecture, while bool is of type int. A simple experiment will show the difference why BOOL and bool can behave differently:

bool ansicBool = 64;
if(ansicBool != true) printf("This will not print\n");

printf("Any given vlaue other than 0 to ansicBool is evaluated to %i\n", ansicBool);

BOOL objcBOOL = 64;
if(objcBOOL != YES) printf("This might print depnding on your architecture\n");

printf("BOOL will keep whatever value you assign it: %i\n", objcBOOL);

if(!objcBOOL) printf("This will not print\n");

printf("! operator will zero objcBOOL %i\n", !objcBOOL);

if(!!objcBOOL) printf("!! will evaluate objcBOOL value to %i\n", !!objcBOOL);

To your surprise if(objcBOOL != YES) will evaluates to 1 by the compiler, since YES is actually the character code 1, and in the eyes of compiler, character code 64 is of course not equal to character code 1 thus the if statement will evaluate to YES/true/1 and the following line will run. However since a none zero bool type always evaluates to the integer value of 1, the above issue will not effect your code. Below are some good tips if you want to use the Objective-C BOOL type vs the ANSI C bool type:

• Always assign the YES or NO value and nothing else.
• Convert BOOL types by using double not !! operator to avoid unexpected results.
• When checking for YES use if(!myBool) instead of if(myBool != YES) it is much cleaner to use the not ! operator and gives the expected result.

Possibly something along these lines:

SELECT CAST(CASE WHEN COUNT(*) > 0 THEN 1 ELSE 0 END AS BIT)
FROM dummy WHERE id = 1;

http://sqlfiddle.com/#!3/5e555/1

In python, not is a boolean operator which gets the opposite of a value:

>>> myval = 0
>>> nyvalue = not myval
>>> nyvalue
True
>>> myval = 1
>>> nyvalue = not myval
>>> nyvalue
False

And True == 1 and False == 0 (if you need to convert it to an integer, you can use int())

In rails, I've previously done something like this:

class ApplicationController < ActionController::Base
  # ...

  private def bool_from(value)
    !!ActiveRecord::Type::Boolean.new.type_cast_from_database(value)
  end
  helper_method :bool_from

  # ...
end

Which is nice if you're trying to match your boolean strings comparisons in the same manner as rails would for your database.

If you want to be case-insensitive, you can just do:

b = True if bool_str.lower() == 'true' else False

Example usage:

>>> bool_str = 'False'
>>> b = True if bool_str.lower() == 'true' else False
>>> b
False
>>> bool_str = 'true'
>>> b = True if bool_str.lower() == 'true' else False
>>> b
True

You can check all value items are true or false by compare your array with the other boolean array via Arrays.equal method like below example :

private boolean isCheckedAnswer(List<Answer> array) {
    boolean[] isSelectedChecks = new boolean[array.size()];
    for (int i = 0; i < array.size(); i++) {
        isSelectedChecks[i] = array.get(i).isChecked();
    }

    boolean[] isAllFalse = new boolean[array.size()];
    for (int i = 0; i < array.size(); i++) {
        isAllFalse[i] = false;
    }

    return !Arrays.equals(isSelectedChecks, isAllFalse);
}

Perhaps bool is a tad "lighter" than Boolean; Interestingly, changing this:

namespace DuckbillServerWebAPI.Models
{
    public class Expense
    {
        . . .
        public bool CanUseOnItems { get; set; }
    }
}

...to this:

namespace DuckbillServerWebAPI.Models
{
    public class Expense
    {
        . . .
        public Boolean CanUseOnItems { get; set; }
    }
}

...caused my cs file to sprout a "using System;" Changing the type back to "bool" caused the using clause's hair to turn grey.

(Visual Studio 2010, WebAPI project)

A funny way to do this is

>>> np.array([True, False, False]) + 0 
np.array([1, 0, 0])

There some kind of old school 'Marxismic' way to the cast int -> bool without C4800 warnings of Microsoft's cl compiler - is to use negation of negation.

int  i  = 0;
bool bi = !!i;

int  j  = 1;
bool bj = !!j;

Try (depending on what result type you want):

Boolean boolean1 = Boolean.valueOf("true");
boolean boolean2 = Boolean.parseBoolean("true");

Advantage:

• Boolean: this does not create new instances of Boolean, so performance is better (and less garbage-collection). It reuses the two instances of either Boolean.TRUE or Boolean.FALSE.
• boolean: no instance is needed, you use the primitive type.

The official documentation is in the Javadoc.

UPDATED:

Autoboxing could also be used, but it has a performance cost.
I suggest to use it only when you would have to cast yourself, not when the cast is avoidable.

This probably harks from the old VB NOT .Net days when bool.ToString produced True or False.

If you like me just need boolean from variable which is string. You can use distils as mentioned earlier by @jzwiener. However I could not import and use the module as he suggested.

Instead I end up using it this way on python3.7

from distutils import util # to handle str to bool conversion
enable_deletion = 'False'
enable_deletion = bool(util.strtobool(enable_deletion))

distutils is part of the python std lib so no need of installation. Which is great!

No, there isn't a boolean type in Oracle Database, but you can do this way:

You can put a check constraint on a column.

If your table hasn't a check column, you can add it:

ALTER TABLE table_name
ADD column_name_check char(1) DEFAULT '1';

When you add a register, by default this column get 1.

Here you put a check that limit the column value, just only put 1 or 0

ALTER TABLE table_name ADD
CONSTRAINT name_constraint 
column_name_check (ONOFF in ( '1', '0' ));

In a strict definition of a boolean element, there are only two values. In a perfect world, that would be true. In the real world, the element may be missing or unknown. Typically, this involves user input. In a screen based system, it could be forced by an edit. In a batch world using either a database or XML input, the element could easily be missing.

So, in the non-perfect world we live in, the Boolean object is great in that it can represent the missing or unknown state as null. After all, computers just model the real world an should account for all possible states and handle them with throwing exceptions (mostly since there are use cases where throwing the exception would be the correct response).

In my case, the Boolean object was the perfect answer since the input XML sometimes had the element missing and I could still get a value, assign it to a Boolean and then check for a null before trying to use a true or false test with it.

Just my 2 cents.

Your issue is in PHPMyAdmin itself. Some versions do not display the value of bit columns, even though you did set it correctly.

Let's see this in action:

var b = true;_x000D_
_x000D_
console.log(b); // true_x000D_
_x000D_
b = !b;_x000D_
console.log(b); // false_x000D_
_x000D_
b = !b;_x000D_
console.log(b); // true

Anyways, there is no shorter way than what you currently have.

You can use Bit DataType in SQL Server to store boolean data.

You can flip a value like so:

myVal = !myVal;

so your code would shorten down to:

switch(wParam) {
    case VK_F11:
    flipVal = !flipVal;
    break;

    case VK_F12:
    otherVal = !otherVal;
    break;

    default:
    break;
}

Use 0 for true and 1 for false.

Sample:

#!/bin/bash

isdirectory() {
  if [ -d "$1" ]
  then
    # 0 = true
    return 0 
  else
    # 1 = false
    return 1
  fi
}


if isdirectory $1; then echo "is directory"; else echo "nopes"; fi

Edit

From @amichair's comment, these are also possible

isdirectory() {
  if [ -d "$1" ]
  then
    true
  else
    false
  fi
}


isdirectory() {
  [ -d "$1" ]
}

There is no format specifier for bool types. However, since any integral type shorter than int is promoted to int when passed down to printf()'s variadic arguments, you can use %d:

bool x = true;
printf("%d\n", x); // prints 1

But why not:

printf(x ? "true" : "false");

or, better:

printf("%s", x ? "true" : "false");

or, even better:

fputs(x ? "true" : "false", stdout);

instead?

You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:

boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))

If it is a String, you could do this:

boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))

Boolean primitive type is atomic for write and read operations, volatile guarantees the happens-before principle. So if you need a simple get() and set() then you don't need the AtomicBoolean.

On the other hand if you need to implement some check before setting the value of a variable, e.g. "if true then set to false", then you need to do this operation atomically as well, in this case use compareAndSet and other methods provided by AtomicBoolean, since if you try to implement this logic with volatile boolean you'll need some synchronization to be sure that the value has not changed between get and set.

In Python 2.x, it is not guaranteed at all:

>>> False = 5
>>> 0 == False
False

So it could change. In Python 3.x, True, False, and None are reserved words, so the above code would not work.

In general, with booleans you should assume that while False will always have an integer value of 0 (so long as you don't change it, as above), True could have any other value. I wouldn't necessarily rely on any guarantee that True==1, but on Python 3.x, this will always be the case, no matter what.

If you're using the variable result:

result = result == "true";

Java 8: Use random generator isolated to the current thread: ThreadLocalRandom nextBoolean()

Like the global Random generator used by the Math class, a ThreadLocalRandom is initialized with an internally generated seed that may not otherwise be modified. When applicable, use of ThreadLocalRandom rather than shared Random objects in concurrent programs will typically encounter much less overhead and contention.

java.util.concurrent.ThreadLocalRandom.current().nextBoolean();

You neglected to say which version of C you are concerned about. Let's assume it's this one:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

As you can see by reading the specification, the standard definitions of true and false are 1 and 0, yes.

If your question is about a different version of C, or about non-standard definitions for true and false, then ask a more specific question.

You cannot.

According to the XML Schema specification, a boolean is true or false. True is not valid:

  3.2.2.1 Lexical representation
  An instance of a datatype that is defined as ·boolean· can have the 
  following legal literals {true, false, 1, 0}. 

  3.2.2.2 Canonical representation
  The canonical representation for boolean is the set of 
  literals {true, false}. 

If the tool you are using truly validates against the XML Schema standard, then you cannot convince it to accept True for a boolean.

MySQL does not have internal boolean data type. It uses the smallest integer data type - TINYINT.

The BOOLEAN and BOOL are equivalents of TINYINT(1), because they are synonyms.

Try to create this table -

CREATE TABLE table1 (
  column1 BOOLEAN DEFAULT NULL
);

Then run SHOW CREATE TABLE, you will get this output -

CREATE TABLE `table1` (
  `column1` tinyint(1) DEFAULT NULL
)

In MySQL TRUE and FALSE are synonyms for TINYINT(1).

So therefore its basically the same thing, but MySQL is converting to 0/1 - so just use a TINYINT if that's easier for you

P.S.
The performance is likely to be so minuscule (if at all), that if you need to ask on StackOverflow, then it won't affect your database :)

You can use Boolean / boolean. Simplicity is the way to go. If you do not need specific api (Collections, Streams, etc.) and you are not foreseeing that you will need them - use primitive version of it (boolean).

1. With primitives you guarantee that you will not pass null values.
   You will not fall in traps like this. The code below throws NullPointerException (from: Booleans, conditional operators and autoboxing):

   public static void main(String[] args) throws Exception { Boolean b = true ? returnsNull() : false; // NPE on this line. System.out.println(b); } public static Boolean returnsNull() { return null; }

2. Use Boolean when you need an object, eg:

   • Stream of Booleans,
   • Optional
   • Collections of Booleans

value = (value) ? false : true;

Conditional (ternary) Operator.

I came across a tutorial which have a well explaination about What values are true and false in Perl. It state that:

Following scalar values are considered false:

• undef - the undefined value
• 0 the number 0, even if you write it as 000 or 0.0
• '' the empty string.
• '0' the string that contains a single 0 digit.

All other scalar values, including the following are true:

• 1 any non-0 number
• ' ' the string with a space in it
• '00' two or more 0 characters in a string
• "0\n" a 0 followed by a newline
• 'true'
• 'false' yes, even the string 'false' evaluates to true.

There is another good tutorial which explain about Perl true and false.

SQL Server does not have literal true or false values. You'll need to use the 1=1 method (or similar) in the rare cases this is needed.

One option is to create your own named variables for true and false

DECLARE @TRUE bit
DECLARE @FALSE bit
SET @TRUE = 1
SET @FALSE = 0

select * from SomeTable where @TRUE = @TRUE

But these will only exist within the scope of the batch (you'll have to redeclare them in every batch in which you want to use them)

T and TRUE are True, F and FALSE are False. T and F can be redefined, however, so you should only rely upon TRUE and FALSE. If you compare 0 to FALSE and 1 to TRUE, you will find that they are equal as well, so you might consider them to be True and False as well.

As long as checker is not null, you may use !checker as posted. This is possible since Java 5, because this Boolean variable will be autoboxed to the primivite boolean value.

#include <stdbool.h>

For someone like me here to copy and paste.

Using true/false removes some bracket clutter...

#! /bin/bash    
#  true_or_false.bash

[ "$(basename $0)" == "bash" ] && sourced=true || sourced=false

$sourced && echo "SOURCED"
$sourced || echo "CALLED"

# Just an alternate way:
! $sourced  &&  echo "CALLED " ||  echo "SOURCED"

$sourced && return || exit

In Java, null only applies to object references; since boolean is a primitive type, it cannot be assigned null.

It's hard to get context from your example, but I'm guessing that if hideInNav is not in the object returned by getProperties(), the (default value?) you've indicated will be false. I suspect this is the bug that you're seeing, as false is not equal to null, so hideNavigation is getting the empty string?

You might get some better answers with a bit more context to your code sample.

This works for everything I expect it to:

add_boolean_argument(parser, 'foo', default=True)
parser.parse_args([])                   # Whatever the default was
parser.parse_args(['--foo'])            # True
parser.parse_args(['--nofoo'])          # False
parser.parse_args(['--foo=true'])       # True
parser.parse_args(['--foo=false'])      # False
parser.parse_args(['--foo', '--nofoo']) # Error

The code:

def _str_to_bool(s):
    """Convert string to bool (in argparse context)."""
    if s.lower() not in ['true', 'false']:
        raise ValueError('Need bool; got %r' % s)
    return {'true': True, 'false': False}[s.lower()]

def add_boolean_argument(parser, name, default=False):                                                                                               
    """Add a boolean argument to an ArgumentParser instance."""
    group = parser.add_mutually_exclusive_group()
    group.add_argument(
        '--' + name, nargs='?', default=default, const=True, type=_str_to_bool)
    group.add_argument('--no' + name, dest=name, action='store_false')

It's according to spec.

12.5 The if Statement 
.....

2. If ToBoolean(GetValue(exprRef)) is true, then 
a. Return the result of evaluating the first Statement. 
3. Else, 
....

ToBoolean, according to the spec, is

The abstract operation ToBoolean converts its argument to a value of type Boolean according to Table 11:

And that table says this about strings:

The result is false if the argument is the empty String (its length is zero); otherwise the result is true

Now, to explain why "0" == false you should read the equality operator, which states it gets its value from the abstract operation GetValue(lref) matches the same for the right-side.

Which describes this relevant part as:

if IsPropertyReference(V), then 
a. If HasPrimitiveBase(V) is false, then let get be the [[Get]] internal method of base, otherwise let get
be the special [[Get]] internal method defined below. 
b. Return the result of calling the get internal method using base as its this value, and passing 
GetReferencedName(V) for the argument

Or in other words, a string has a primitive base, which calls back the internal get method and ends up looking false.

If you want to evaluate things using the GetValue operation use ==, if you want to evaluate using the ToBoolean, use === (also known as the "strict" equality operator)

Depends on what you mean by "efficient". Performance-wise both versions are the same as its the same bytecode.

$ ./javap.exe -c java.lang.String | grep -A 10 "valueOf(boolean)"
  public static java.lang.String valueOf(boolean);
    Code:
       0: iload_0
       1: ifeq          9
       4: ldc           #14                 // String true
       6: goto          11
       9: ldc           #10                 // String false

       4: ldc           #3                  // String true
       6: goto          11
       9: ldc           #2                  // String false
      11: areturn

Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values

I prefer to use mutex mechanism in such cases, but if you really want to use boolean, then you should declare it as volatile (to provide the change visibility across threads) and just run the body-less cycle with that boolean as a condition :

//.....some class

volatile boolean someBoolean; 

Thread someThread = new Thread() {

    @Override 
    public void run() {
        //some actions
        while (!someBoolean); //wait for condition 
        //some actions 
    }

};

If you're using MVC 3 and Razor you can also use the following:

@Html.RadioButtonFor(model => model.blah, true) Yes
@Html.RadioButtonFor(model => model.blah, false) No

(boolean)json_decode(strtolower($string))

It handles all possible variants of $string

'true'  => true
'True'  => true
'1'     => true
'false' => false
'False' => false
'0'     => false
'foo'   => false
''      => false

Actually, the entire approach would be cleaner if you only had to use one instance of StringBuffer, instead of creating one in every recursive call... I would go for:

private String getWhoozitYs(){
     StringBuffer sb = new StringBuffer();
     while (generator.nextBoolean()) {
         sb.append("y");
     }

     return sb.toString();
}

After reading all the answers and comments on this question, I thought to do a small experiment.

I generated 50,000 random booleans and called sum and count on them.

Here are my results:

>>> a = [bool(random.getrandbits(1)) for x in range(50000)]
>>> len(a)
50000
>>> a.count(False)
24884
>>> a.count(True)
25116
>>> def count_it(a):
...   curr = time.time()
...   counting = a.count(True)
...   print("Count it = " + str(time.time() - curr))
...   return counting
... 
>>> def sum_it(a):
...   curr = time.time()
...   counting = sum(a)
...   print("Sum it = " + str(time.time() - curr))
...   return counting
... 
>>> count_it(a)
Count it = 0.00121307373046875
25015
>>> sum_it(a)
Sum it = 0.004102230072021484
25015

Just to be sure, I repeated it several more times:

>>> count_it(a)
Count it = 0.0013530254364013672
25015
>>> count_it(a)
Count it = 0.0014507770538330078
25015
>>> count_it(a)
Count it = 0.0013344287872314453
25015
>>> sum_it(a)
Sum it = 0.003480195999145508
25015
>>> sum_it(a)
Sum it = 0.0035257339477539062
25015
>>> sum_it(a)
Sum it = 0.003350496292114258
25015
>>> sum_it(a)
Sum it = 0.003744363784790039
25015

And as you can see, count is 3 times faster than sum. So I would suggest to use count as I did in count_it.

If you want True False use:

"%s %s" % (True, False)

because str(True) is 'True' and str(False) is 'False'.

or if you want 1 0 use:

"%i %i" % (True, False)

because int(True) is 1 and int(False) is 0.

numpy.full((2,2), True, dtype=bool)

Bill Parker is getting voted down, because his definitions are reversed from the normal code convention. Normally, true is defined as 0 and false is defined as nonzero. 1 will work for false, as will 9999 and -1. The same with function return values - 0 is success and anything nonzero is failure. Sorry, I don't have the street credibility yet to vote or to reply to him directly.

Bash recommends using double brackets now as a habit instead of single brackets, and the link Mike Holt gave explains the differences in how they work. 7.3. Other Comparison Operators

For one thing, -eq is a numerical operator, so having the code

#**** NOTE *** This gives error message *****
The_world_is_flat=0;
if [ "${The_world_is_flat}" -eq true ]; then

will issue an error statement, expecting an integer expression. This applies to either parameter, as neither is an integer value. Yet, if we put double brackets around it, it will not issue an error statement, but it will yield a wrong value (well, in 50% of the possible permutations). It will evaluate to [[0 -eq true]] = success, but also to [[0 -eq false]] = success, which is wrong (hmmm.... what about that builtin being a numerical value?).

#**** NOTE *** This gives wrong output *****
The_world_is_flat=true;
if [[ "${The_world_is_flat}" -eq true ]]; then

There are other permutations of the conditional which will give wrong output as well. Basically, anything (other than the error condition listed above) that sets a variable to a numerical value and compares it to a true/false builtin, or sets a variable to a true/false builtin and compares it to a numerical value. Also, anything that sets a variable to a true/false builtin and does a comparison using -eq. So avoid -eq for Boolean comparisons and avoid using numerical values for Boolean comparisons. Here's a summary of the permutations that will give invalid results:

# With variable set as an integer and evaluating to true/false
# *** This will issue error warning and not run: *****
The_world_is_flat=0;
if [ "${The_world_is_flat}" -eq true ]; then

# With variable set as an integer and evaluating to true/false
# *** These statements will not evaluate properly: *****
The_world_is_flat=0;
if [ "${The_world_is_flat}" -eq true ]; then
#
if [[ "${The_world_is_flat}" -eq true ]]; then
#
if [ "${The_world_is_flat}" = true ]; then
#
if [[ "${The_world_is_flat}" = true ]]; then
#
if [ "${The_world_is_flat}" == true ]; then
#
if [[ "${The_world_is_flat}" == true ]]; then


# With variable set as an true/false builtin and evaluating to true/false
# *** These statements will not evaluate properly: *****
The_world_is_flat=true;
if [[ "${The_world_is_flat}" -eq true ]]; then
#
if [ "${The_world_is_flat}" = 0 ]; then
#
if [[ "${The_world_is_flat}" = 0 ]]; then
#
if [ "${The_world_is_flat}" == 0 ]; then
#
if [[ "${The_world_is_flat}" == 0 ]]; then

So, now to what works. Use true/false builtins for both your comparison and your evaluations (as Mike Hunt noted, don't enclose them in quotes). Then use either or single or double equal sign (= or ==) and either single or double brackets ([ ] or [[ ]]). Personally, I like the double equals sign, because it reminds me of logical comparisons in other programming languages, and double quotes just because I like typing. So these work:

# With variable set as an integer and evaluating to true/false
# *** These statements will work properly: *****
#
The_world_is_flat=true/false;
if [ "${The_world_is_flat}" = true ]; then
#
if [[ "${The_world_is_flat}" = true ]]; then
#
if [ "${The_world_is_flat}" = true ]; then
#
if [[ "${The_world_is_flat}" == true ]]; then

There you have it.

There is no default for Boolean. Boolean must be constructed with a boolean or a String. If the object is unintialized, it would point to null.

The default value of primitive boolean is false.

http://download.oracle.com/javase/6/docs/api/java/lang/Boolean.html
https://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

See oracle docs

public static boolean parseBoolean(String s) {
        return ((s != null) && s.equalsIgnoreCase("true"));
    }

The not operator (logical negation)

Probably the best way is using the operator not:

>>> value = True
>>> not value
False

>>> value = False
>>> not value
True

So instead of your code:

if bool == True:
    return False
else:
    return True

You could use:

return not bool

The logical negation as function

There are also two functions in the operator module operator.not_ and it's alias operator.__not__ in case you need it as function instead of as operator:

>>> import operator
>>> operator.not_(False)
True
>>> operator.not_(True)
False

These can be useful if you want to use a function that requires a predicate-function or a callback.

For example map or filter:

>>> lst = [True, False, True, False]
>>> list(map(operator.not_, lst))
[False, True, False, True]

>>> lst = [True, False, True, False]
>>> list(filter(operator.not_, lst))
[False, False]

Of course the same could also be achieved with an equivalent lambda function:

>>> my_not_function = lambda item: not item

>>> list(map(my_not_function, lst))
[False, True, False, True]

Do not use the bitwise invert operator ~ on booleans

One might be tempted to use the bitwise invert operator ~ or the equivalent operator function operator.inv (or one of the other 3 aliases there). But because bool is a subclass of int the result could be unexpected because it doesn't return the "inverse boolean", it returns the "inverse integer":

>>> ~True
-2
>>> ~False
-1

That's because True is equivalent to 1 and False to 0 and bitwise inversion operates on the bitwise representation of the integers 1 and 0.

So these cannot be used to "negate" a bool.

Negation with NumPy arrays (and subclasses)

If you're dealing with NumPy arrays (or subclasses like pandas.Series or pandas.DataFrame) containing booleans you can actually use the bitwise inverse operator (~) to negate all booleans in an array:

>>> import numpy as np
>>> arr = np.array([True, False, True, False])
>>> ~arr
array([False,  True, False,  True])

Or the equivalent NumPy function:

>>> np.bitwise_not(arr)
array([False,  True, False,  True])

You cannot use the not operator or the operator.not function on NumPy arrays because these require that these return a single bool (not an array of booleans), however NumPy also contains a logical not function that works element-wise:

>>> np.logical_not(arr)
array([False,  True, False,  True])

That can also be applied to non-boolean arrays:

>>> arr = np.array([0, 1, 2, 0])
>>> np.logical_not(arr)
array([ True, False, False,  True])

Customizing your own classes

not works by calling bool on the value and negate the result. In the simplest case the truth value will just call __bool__ on the object.

So by implementing __bool__ (or __nonzero__ in Python 2) you can customize the truth value and thus the result of not:

class Test(object):
    def __init__(self, value):
        self._value = value

    def __bool__(self):
        print('__bool__ called on {!r}'.format(self))
        return bool(self._value)

    __nonzero__ = __bool__  # Python 2 compatibility

    def __repr__(self):
        return '{self.__class__.__name__}({self._value!r})'.format(self=self)

I added a print statement so you can verify that it really calls the method:

>>> a = Test(10)
>>> not a
__bool__ called on Test(10)
False

Likewise you could implement the __invert__ method to implement the behavior when ~ is applied:

class Test(object):
    def __init__(self, value):
        self._value = value

    def __invert__(self):
        print('__invert__ called on {!r}'.format(self))
        return not self._value

    def __repr__(self):
        return '{self.__class__.__name__}({self._value!r})'.format(self=self)

Again with a print call to see that it is actually called:

>>> a = Test(True)
>>> ~a
__invert__ called on Test(True)
False

>>> a = Test(False)
>>> ~a
__invert__ called on Test(False)
True

However implementing __invert__ like that could be confusing because it's behavior is different from "normal" Python behavior. If you ever do that clearly document it and make sure that it has a pretty good (and common) use-case.

Use the privbind utility: it allows an unprivileged application to bind to reserved ports.

You can read that here

If you use

{{<br />}}

it'll be escaped. If you want raw html, you gotta use

{{{<br />}}}

EDIT (Feb 5 2017): As @hitautodestruct points out, in vue 2 you should use v-html instead of triple curly braces.

When clicking on the button for search you can find it without a loop.
Just add to the option an attribute with the value you need (like id) and search for it specific.

$('#search_wrapper button').on('click', function(){
console.log($('option[value="'+ 
$('#autocomplete_input').val() +'"]').data('value'));
})

The reason you are not receiving the event is because the absolutely positioned element is not a child of the element you are wanting to "click" (blue div). The cleanest way I can think of is to put the absolute element as a child of the one you want clicked, but I'm assuming you can't do that or you wouldn't have posted this question here :)

Another option would be to register a click event handler for the absolute element and call the click handler for the blue div, causing them both to flash.

Due to the way events bubble up through the DOM I'm not sure there is a simpler answer for you, but I'm very curious if anyone else has any tricks I don't know about!

UPDATE : check Peter's answer below for a builtin solution :

This is a helper to set a persistent cookie:

import datetime

def set_cookie(response, key, value, days_expire=7):
    if days_expire is None:
        max_age = 365 * 24 * 60 * 60  # one year
    else:
        max_age = days_expire * 24 * 60 * 60
    expires = datetime.datetime.strftime(
        datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age),
        "%a, %d-%b-%Y %H:%M:%S GMT",
    )
    response.set_cookie(
        key,
        value,
        max_age=max_age,
        expires=expires,
        domain=settings.SESSION_COOKIE_DOMAIN,
        secure=settings.SESSION_COOKIE_SECURE or None,
    )

Use the following code before sending a response.

def view(request):
    response = HttpResponse("hello")
    set_cookie(response, 'name', 'jujule')
    return response

UPDATE : check Peter's answer below for a builtin solution :

for ex.

<input b="demo">

And

(input[@b='demo'])[1]

I have found the browser referer implementation to be really inconsistent.

For example, an anchor element with the "download" attribute works as expected in Safari and sends the referer, but in Chrome the referer will be empty or "-" in the web server logs.

<a href="http://foo.com/foo" download="bar">click to download</a>

Is broken in Chrome - no referer sent.

Try this one. it works for me. :)

I also disabled Hyper-V to makes mine work.

Genymotion FAQ

To date, VirtualBox is not yet fully compatible with Windows 10. As Genymotion relies on the use of VirtualBox in the background, some problems may arise. If you have any troubles running Genymotion on Windows 10, we first recommend that you put VirtualBox in a clean state. To do so:

1. Uninstall VirtualBox.Reboot your computer if prompted by the installer.
2. Install the version of VirtualBox recommended for Windows 10 Reboot your computer if prompted by the installer.
3. Open VirtualBox and go to File > Preferences > Network.
4. Remove all existing host-only networks by clicking Description 1.
5. Start Genymotion a first time.
6. In the event of a failure, start Genymotion a second time.

If Genymotion still doesn’t run, you can manually configure a host-only network:

1. Open VirtualBox and go to File > Preferences > Network.
2. Add a new host-only network by clicking Description 1.
3. Edit its configuration by clicking Description 1.
4. In the Adapter tab, set the following values: IPv4 Address: 192.168.56.1 IPv4 Network Mask: 255.255.255.0
5. In the DHCP Server tab, set the following values: Check Enable Server. Server Address: 192.168.56.100 Server Mask: 255.255.255.0 Lower Address Bound: 192.168.56.101 Upper Address Bound: 192.168.56.254

If you are a windows user and using python 3, then this post will help you to do parallel programming in python.when you run a usual multiprocessing library's pool programming, you will get an error regarding the main function in your program. This is because the fact that windows has no fork() functionality. The below post is giving a solution to the mentioned problem .

http://python.6.x6.nabble.com/Multiprocessing-Pool-woes-td5047050.html

Since I was using the python 3, I changed the program a little like this:

from types import FunctionType
import marshal

def _applicable(*args, **kwargs):
  name = kwargs['__pw_name']
  code = marshal.loads(kwargs['__pw_code'])
  gbls = globals() #gbls = marshal.loads(kwargs['__pw_gbls'])
  defs = marshal.loads(kwargs['__pw_defs'])
  clsr = marshal.loads(kwargs['__pw_clsr'])
  fdct = marshal.loads(kwargs['__pw_fdct'])
  func = FunctionType(code, gbls, name, defs, clsr)
  func.fdct = fdct
  del kwargs['__pw_name']
  del kwargs['__pw_code']
  del kwargs['__pw_defs']
  del kwargs['__pw_clsr']
  del kwargs['__pw_fdct']
  return func(*args, **kwargs)

def make_applicable(f, *args, **kwargs):
  if not isinstance(f, FunctionType): raise ValueError('argument must be a function')
  kwargs['__pw_name'] = f.__name__  # edited
  kwargs['__pw_code'] = marshal.dumps(f.__code__)   # edited
  kwargs['__pw_defs'] = marshal.dumps(f.__defaults__)  # edited
  kwargs['__pw_clsr'] = marshal.dumps(f.__closure__)  # edited
  kwargs['__pw_fdct'] = marshal.dumps(f.__dict__)   # edited
  return _applicable, args, kwargs

def _mappable(x):
  x,name,code,defs,clsr,fdct = x
  code = marshal.loads(code)
  gbls = globals() #gbls = marshal.loads(gbls)
  defs = marshal.loads(defs)
  clsr = marshal.loads(clsr)
  fdct = marshal.loads(fdct)
  func = FunctionType(code, gbls, name, defs, clsr)
  func.fdct = fdct
  return func(x)

def make_mappable(f, iterable):
  if not isinstance(f, FunctionType): raise ValueError('argument must be a function')
  name = f.__name__    # edited
  code = marshal.dumps(f.__code__)   # edited
  defs = marshal.dumps(f.__defaults__)  # edited
  clsr = marshal.dumps(f.__closure__)  # edited
  fdct = marshal.dumps(f.__dict__)  # edited
  return _mappable, ((i,name,code,defs,clsr,fdct) for i in iterable)

After this function , the above problem code is also changed a little like this:

from multiprocessing import Pool
from poolable import make_applicable, make_mappable

def cube(x):
  return x**3

if __name__ == "__main__":
  pool    = Pool(processes=2)
  results = [pool.apply_async(*make_applicable(cube,x)) for x in range(1,7)]
  print([result.get(timeout=10) for result in results])

And I got the output as :

[1, 8, 27, 64, 125, 216]

I am thinking that this post may be useful for some of the windows users.

for(std::map<std::string, std::map<std::string, std::string> >::iterator outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(std::map<std::string, std::string>::iterator inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

or nicer in C++0x:

for(auto outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(auto inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

This is documented in the 'R Installation and Administration' manual that came with your installation.

On my Linux box:

R> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"      
[3] "/usr/lib/R/library"           
R> 

meaning that the default path is the first of these. You can override that via an argument to both install.packages() (from inside R) or R CMD INSTALL (outside R).

You can also override by setting the R_LIBS_USER variable.

The path to the nginx.conf file which is the primary Configuration file for Nginx - which is also the file which shall INCLUDE the Path for other Nginx Config files as and when required is /etc/nginx/nginx.conf.

You may access and edit this file by typing this at the terminal

cd /etc/nginx

/etc/nginx$ sudo nano nginx.conf

Further in this file you may Include other files - which can have a SERVER directive as an independent SERVER BLOCK - which need not be within the HTTP or HTTPS blocks, as is clarified in the accepted answer above.

I repeat - if you need a SERVER BLOCK to be defined within the PRIMARY Config file itself than that SERVER BLOCK will have to be defined within an enclosing HTTP or HTTPS block in the /etc/nginx/nginx.conf file which is the primary Configuration file for Nginx.

Also note -its OK if you define , a SERVER BLOCK directly not enclosing it within a HTTP or HTTPS block , in a file located at path /etc/nginx/conf.d . Also to make this work you will need to include the path of this file in the PRIMARY Config file as seen below :-

http{
    include /etc/nginx/conf.d/*.conf; #includes all files of file type.conf
}

Further to this you may comment out from the PRIMARY Config file , the line

http{
    #include /etc/nginx/sites-available/some_file.conf; # Comment Out 
    include /etc/nginx/conf.d/*.conf; #includes all files of file type.conf
}

and need not keep any Config Files in /etc/nginx/sites-available/ and also no need to SYMBOLIC Link them to /etc/nginx/sites-enabled/ , kindly note this works for me - in case anyone think it doesnt for them or this kind of config is illegal etc etc , pls do leave a comment so that i may correct myself - thanks .

EDIT :- According to the latest version of the Official Nginx CookBook , we need not create any Configs within - /etc/nginx/sites-enabled/ , this was the older practice and is DEPRECIATED now .

Thus No need for the INCLUDE DIRECTIVE include /etc/nginx/sites-available/some_file.conf; .

Quote from Nginx CookBook page - 5 .

"In some package repositories, this folder is named sites-enabled, and configuration files are linked from a folder named site-available; this convention is depre- cated."

Update for XAMPP 7.3.*

If you get into same problem for phpmyadmin in the newest XAMPP, as I had.

The solution is written inside the official documentation located in [XAMPP IP]/dashboard/docs/access-phpmyadmin-remotely.html

To enable remote access to phpMyAdmin from other hosts, follow these steps:

1. Launch the stack manager by double-clicking the XAMPP icon in the mounted disk image.

2. Ensure that Apache and MySQL services are running in the "Services" tab of the stack manager (or start them as needed).

3. Open a new terminal from the "General" tab of the stack manager.

4. Edit the /opt/lampp/etc/extra/httpd-xampp.conf file.

5. Within this file, find the block <Directory "/opt/lampp/phpmyadmin">

Update this block and replace Require local with Require all granted,

6. Save the file and restart the Apache service using the stack manager.

Note for section (4) To edit this file make sure you have vim installed.

Note for section (5) Instead of allowing access to all, which is highly insecure, if your computer is connected to a network. A safer approach is to limit the access to only set of IPs as suggested by @Gunnar Bernstein.

In my case I did:

<Directory "/opt/lampp/phpmyadmin">
  AllowOverride AuthConfig Limit
  Require local
  Require ip 192.168
  ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

You can simply write :

class A(object):

    def __init__(self):
        print "Initialiser A was called"

class B(A):

    def __init__(self):
        A.__init__(self)
        # A.__init__(self,<parameters>) if you want to call with parameters
        print "Initialiser B was called"

class C(B):

    def __init__(self):
        # A.__init__(self) # if you want to call most super class...
        B.__init__(self)
        print "Initialiser C was called"

as long as you did not commit you can type

git merge --abort

just as the command line suggested.

Adapted from a grep in python.

Accepts a list of filenames via [2:], does no exception handling:

#!/usr/bin/env python
import re, sys, os

for f in filter(os.path.isfile, sys.argv[2:]):
    for line in open(f).readlines():
        if re.match(sys.argv[1], line):
            print line

sys.argv[1] resp sys.argv[2:] works, if you run it as an standalone executable, meaning

chmod +x

first

I added this code

<input class="form-control input-small hasDatepicker" id="datepicker6" name="expire_date" type="text" value="2018-03-17 00:00:00">

<script src="/assets/js/datepicker/bootstrap-datepicker.js"></script>
<script>
        $(document).ready(function() {
            $("#datepicker6").datepicker({
                isRTL: true,
                dateFormat: "yy/mm/dd 23:59:59",
                changeMonth: true,
                changeYear: true

            });
        });
</script>

It is better to process HTML as a template than to build nodes via JavaScript (HTML is not XML after all.) You can keep your IFRAME's HTML syntax clean by using a template and then appending the template's contents into another DIV.

<div id="placeholder"></div>

<script id="iframeTemplate" type="text/html">
    <iframe src="...">
        <!-- replace this line with alternate content -->
    </iframe>
</script>

<script type="text/javascript">
var element,
    html,
    template;

element = document.getElementById("placeholder");
template = document.getElementById("iframeTemplate");
html = template.innerHTML;

element.innerHTML = html;
</script>

The problem is with the way you are printing the Time data

java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());
System.out.println(sa); //this will print the milliseconds as the toString() has been written in that format

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(timestamp)); //this will print without ms

You can pass an enum through as a string.

public enum CountType {
    ONE,
    TWO,
    THREE
}

private CountType count;
count = ONE;

String countString = count.name();

CountType countToo = CountType.valueOf(countString);

Given strings are supported you should be able to pass the value of the enum around with no problem.

There's so much confusion around this subject, and none of the existing answers cover everything clearly and directly. Here are some examples with comments inline.

//this is a declaration
var foo;

//this is an assignment
bar = 3;

//this is a declaration and an assignment
var dual = 5;

A declaration sets a DontDelete flag. An assignment does not.

A declaration ties that variable to the current scope.

A variable assigned but not declared will look for a scope to attach itself to. That means it will traverse up the food-chain of scope until a variable with the same name is found. If none is found, it will be attached to the top-level scope (which is commonly referred to as global).

function example(){
  //is a member of the scope defined by the function example
  var foo;

  //this function is also part of the scope of the function example
  var bar = function(){
     foo = 12; // traverses scope and assigns example.foo to 12
  }
}

function something_different(){
     foo = 15; // traverses scope and assigns global.foo to 15
}

For a very clear description of what is happening, this analysis of the delete function covers variable instantiation and assignment extensively.

jQuery Version

JavaScript (modified from a script I found on someone's site - I just can't find the site again, so I can't give the person credit):

$(document).ready(function() {
  $("#bookmarkme").click(function() {
    if (window.sidebar) { // Mozilla Firefox Bookmark
      window.sidebar.addPanel(location.href,document.title,"");
    } else if(window.external) { // IE Favorite
      window.external.AddFavorite(location.href,document.title); }
    else if(window.opera && window.print) { // Opera Hotlist
      this.title=document.title;
      return true;
    }
  });
});

HTML:

<a id="bookmarkme" href="#" rel="sidebar" title="bookmark this page">Bookmark This Page</a>

IE will show an error if you don't run it off a server (it doesn't allow JavaScript bookmarks via JavaScript when viewing it as a file://...).

Just an example:

template <class key, class value>
class insertIntoVec
{
public:
    insertIntoVec(std::vector<value>& vec_in):m_vec(vec_in)
    {}

    void operator () (const std::pair<key, value>& rhs)  
    {   
        m_vec.push_back(rhs.second);
    }

private:
    std::vector<value>& m_vec;
};

int main()
{
std::map<int, std::string> aMap;
aMap[1] = "test1";
aMap[2] = "test2";
aMap[3] = "test3";
aMap[4] = "test4";

std::vector<std::string> aVec;

aVec.reserve(aMap.size());
std::for_each(aMap.begin(), aMap.end(),
          insertIntoVec<int, std::string>(aVec) 
    );

}

This is an old question, but it came up first for me in google results when searching "mongoose insert array of documents".

There are two options model.create() [mongoose] and model.collection.insert() [mongodb] which you can use. View a more thorough discussion here of the pros/cons of each option:

Mongoose (mongodb) batch insert?

Babel supports class variables in ESNext, check this example:

class Foo {
  bar = 2
  static iha = 'string'
}

const foo = new Foo();
console.log(foo.bar, foo.iha, Foo.bar, Foo.iha);
// 2, undefined, undefined, 'string'

I know this is an old question, but we were faced with the same problem when trying to inject Strings. So we invented a JUnit5/Mockito extension that does exactly what you want: https://github.com/exabrial/mockito-object-injection

EDIT:

@InjectionMap
 private Map<String, Object> injectionMap = new HashMap<>();

 @BeforeEach
 public void beforeEach() throws Exception {
  injectionMap.put("securityEnabled", Boolean.TRUE);
 }

 @AfterEach
 public void afterEach() throws Exception {
  injectionMap.clear();
 }

<script> is HTML 5.

<script type='text/javascript'> is HTML 4.x (and XHTML 1.x).

<script language="javascript"> is HTML 3.2.

Is it different for different webservers?

No.

when I did an offline javascript test, i realised that i need the <script type = 'text/javascript'> tag.

That isn't the case. Something else must have been wrong with your test case.

I found a much simpler alternative way to generating soap message. Given a Person Object:

import com.fasterxml.jackson.annotation.JsonInclude;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
  private String name;
  private int age;
  private String address; //setter and getters below
}

Below is a simple Soap Message Generator:

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

@Slf4j
public class SoapGenerator {

  protected static final ObjectMapper XML_MAPPER = new XmlMapper()
      .enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
      .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
      .configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
      .registerModule(new JavaTimeModule());

  private static final String SOAP_BODY_OPEN = "<soap:Body>";
  private static final String SOAP_BODY_CLOSE = "</soap:Body>";
  private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
  private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";

  public static String soapWrap(String xml) {
    return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
  }

  public static String soapUnwrap(String xml) {
    return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
  }
}

You can use by:

 public static void main(String[] args) throws Exception{
        Person p = new Person();
        p.setName("Test");
        p.setAge(12);

        String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
        log.info("Generated String");
        log.info(xml);
      }

Think of the null as "unknown" in that case (or "does not exist"). In either of those cases, you can't say that they are equal, because you don't know the value of either of them. So, null=null evaluates to not true (false or null, depending on your system), because you don't know the values to say that they ARE equal. This behavior is defined in the ANSI SQL-92 standard.

EDIT: This depends on your ansi_nulls setting. if you have ANSI_NULLS off, this WILL evaluate to true. Run the following code for an example...

set ansi_nulls off

if null = null
    print 'true'
else
    print 'false'


set ansi_nulls ON

if null = null
    print 'true'
else
    print 'false'

You can also use RedirectMatch directive to deny access to a folder.

To deny access to a folder, you can use the following RedirectMatch in htaccess :

 RedirectMatch 403 ^/folder/?$

This will forbid an external access to /folder/ eg : http://example.com/folder/ will return a 403 forbidden error.

To deny access to everything inside the folder, You can use this :

RedirectMatch 403 ^/folder/.*$

This will block access to the entire folder eg : http://example.com/folder/anyURI will return a 403 error response to client.

If you are using MySQL you can do it like this:

SELECT '2008-12-31 23:59:59' + INTERVAL 30 MINUTE;

For a pure PHP solution use strtotime

strtotime('+ 30 minute',$yourdate);

One more solution:

function firstOrNull(array, expr) {
  for (var i = 0; i < array.length; i++) {
    if (expr(array[i]))
      return array[i];
    }
  return null;
}

Using: firstOrNull([{ a: 1, b: 2 }, { a: 3, b: 3 }], function(item) { return item.a === 3; });

This function don't executes for each element from the array (it's valuable for large arrays)

Create a new folder, let's say local-maven-repo at the root of your Maven project.

Just add a local repo iside your <project> of your pom.xml:

<repositories>
    <repository>
        <id>local-maven-repo</id>
        <url>file:///${project.basedir}/local-maven-repo</url>
    </repository>
</repositories>

Then for each external jar you want to install, go at the root of your project and execute:

mvn deploy:deploy-file -DgroupId=[GROUP] -DartifactId=[ARTIFACT] -Dversion=[VERS] -Durl=file:./local-maven-repo/ -DrepositoryId=local-maven-repo -DupdateReleaseInfo=true -Dfile=[FILE_PATH]

(Copied from my reply on a similar question)

Modify the DataNode class so that it implements Comparable interface.

public int compareTo(DataNode o)
{
     return(degree - o.degree);
}

then just use

Collections.sort(nodeList);

Try use the library : https://imapx.codeplex.com/

That library free, open source and have example at this : https://imapx.codeplex.com/wikipage?title=Sample%20code%20for%20get%20messages%20from%20your%20inbox

If linking to the shell Lightweight API (shlwapi.dll) is ok for you, you can use the PathIsDirectory function

I observed this issue while using Eclipse. I needed to add encoding in my pom.xml file and it resolved. http://ctrlaltsolve.blogspot.in/2015/11/encoding-properties-in-maven.html

The bootstrap 3 docs for horizontal forms let you use the .form-horizontal class to make your form labels and inputs vertically aligned. The structure for these forms is:

<form class="form-horizontal" role="form">
  <div class="form-group">
    <label for="input1" class="col-lg-2 control-label">Label1</label>
    <div class="col-lg-10">
      <input type="text" class="form-control" id="input1" placeholder="Input1">
    </div>
  </div>
  <div class="form-group">
    <label for="input2" class="col-lg-2 control-label">Label2</label>
    <div class="col-lg-10">
      <input type="password" class="form-control" id="input2" placeholder="Input2">
    </div>
  </div>
</form>

Therefore, your form should look like this:

<form class="form-horizontal" role="form">
    <div class="form-group">
        <div class="col-xs-3">
            <label for="class_type"><h2><span class=" label label-primary">Class Type</span></h2></label>
        </div>
        <div class="col-xs-2">
            <select id="class_type" class="form-control input-lg" autocomplete="off">
                <option>Economy</option>
                <option>Premium Economy</option>
                <option>Club World</option>
                <option>First Class</option>
            </select>
        </div>
    </div>
</form>

How are you loading this page? Is it getting anything on POST to load? If it's not, then the $name = $_POST['Name']; assignation doesn't have any 'Name' on POST.

Just for completeness: a build might be slow because the build system is being stupid as well as because the compiler is taking a long time to do its work.

.text-right {

.text-center {
  text-align: center;
}

bootstrap has added three css classes for text align.

Follow this:

• start Automator.app
• select Application
• click Show library in the toolbar (if hidden)
• add Run shell script (from the Actions/Utilities)
• copy & paste your script into the window
• test it

• save somewhere (for example you can make an Applications folder in your HOME, you will get an your_name.app)

• go to System Preferences -> Accounts -> Login items

• add this app
• test & done ;)

EDIT:

I've recently earned a "Good answer" badge for this answer. While my solution is simple and working, the cleanest way to run any program or shell script at login time is described in @trisweb's answer, unless, you want interactivity.

With automator solution you can do things like next:

so, asking to run a script or quit the app, asking passwords, running other automator workflows at login time, conditionally run applications at login time and so on...

Update: This should probably be the accepted answer since maxElement appeared in Swift.

Use the almighty reduce:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, { max($0, $1) })

Similarly:

let numMin = nums.reduce(Int.max, { min($0, $1) })

reduce takes a first value that is the initial value for an internal accumulator variable, then applies the passed function (here, it's anonymous) to the accumulator and each element of the array successively, and stores the new value in the accumulator. The last accumulator value is then returned.

Use the jQuery ajaxSetup function, that can set up default values for all ajax requests.

$.ajaxSetup({
  headers: {
    'Authorization': "Basic XXXXX"
  }
});

simply do this..

@Override
public void onBackPressed() {
    //super.onBackPressed();
}

commenting out the //super.onBackPressed(); will do the trick

As a quick addition, and I'm surprised nobody has thought of this, you could use the in operator:

"chrome" in window

Obviously this isn't using JQuery, but I figured I'd put it since it's handy for times when you aren't using any external libraries.

for people who need CGO enabled and cross compile from OSX targeting windows

I needed CGO enabled while compiling for windows from my mac since I had imported the https://github.com/mattn/go-sqlite3 and it needed it. Compiling according to other answers gave me and error:

/usr/local/go/src/runtime/cgo/gcc_windows_amd64.c:8:10: fatal error: 'windows.h' file not found

If you're like me and you have to compile with CGO. This is what I did:

1.We're going to cross compile for windows with a CGO dependent library. First we need a cross compiler installed like mingw-w64

brew install mingw-w64

This will probably install it here /usr/local/opt/mingw-w64/bin/.

2.Just like other answers we first need to add our windows arch to our go compiler toolchain now. Compiling a compiler needs a compiler (weird sentence) compiling go compiler needs a separate pre-built compiler. We can download a prebuilt binary or build from source in a folder eg: ~/Documents/go now we can improve our Go compiler, according to top answer but this time with CGO_ENABLED=1 and our separate prebuilt compiler GOROOT_BOOTSTRAP(Pooya is my username):

cd /usr/local/go/src
sudo GOOS=windows GOARCH=amd64 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean
sudo GOOS=windows GOARCH=386 CGO_ENABLED=1 GOROOT_BOOTSTRAP=/Users/Pooya/Documents/go ./make.bash --no-clean

3.Now while compiling our Go code use mingw to compile our go file targeting windows with CGO enabled:

GOOS="windows" GOARCH="386" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/i686-w64-mingw32-gcc" go build hello.go
GOOS="windows" GOARCH="amd64" CGO_ENABLED="1" CC="/usr/local/opt/mingw-w64/bin/x86_64-w64-mingw32-gcc" go build hello.go

Interesting blog post here:

http://geekswithblogs.net/cskardon/archive/2008/06/23/dispose-of-a-wpf-usercontrol-ish.aspx

It mentions subscribing to Dispatcher.ShutdownStarted to dispose of your resources.

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

In your first example, what happens if run_code1() raises an exception that is not TypeError? ... other_code() will not be executed.

Compare that with the finally: version: other_code() is guaranteed to be executed regardless of any exception being raised.

You can do $this->getRequest()->query->all(); to get all GET params and $this->getRequest()->request->all(); to get all POST params.

So in your case:

$params = $this->getRequest()->request->all();
$params['value1'];
$params['value2'];

For more info about the Request class, see http://api.symfony.com/2.8/Symfony/Component/HttpFoundation/Request.html

The best I can find is to set input[type="password"] {font:small-caption;font-size:16px}

Demo:

input {_x000D_
  font: small-caption;_x000D_
  font-size: 16px;_x000D_
}

<input type="password">

For a more detailed answer on creating your own colormaps, I highly suggest visiting this page

If that answer is too much work, you can quickly make your own list of colors and pass them to the color parameter. All the colormaps are in the cm matplotlib module. Let's get a list of 30 RGB (plus alpha) color values from the reversed inferno colormap. To do so, first get the colormap and then pass it a sequence of values between 0 and 1. Here, we use np.linspace to create 30 equally-spaced values between .4 and .8 that represent that portion of the colormap.

from matplotlib import cm
color = cm.inferno_r(np.linspace(.4, .8, 30))
color

array([[ 0.865006,  0.316822,  0.226055,  1.      ],
       [ 0.851384,  0.30226 ,  0.239636,  1.      ],
       [ 0.832299,  0.283913,  0.257383,  1.      ],
       [ 0.817341,  0.270954,  0.27039 ,  1.      ],
       [ 0.796607,  0.254728,  0.287264,  1.      ],
       [ 0.775059,  0.239667,  0.303526,  1.      ],
       [ 0.758422,  0.229097,  0.315266,  1.      ],
       [ 0.735683,  0.215906,  0.330245,  1.      ],
       .....

Then we can use this to plot, using the data from the original post:

import random
x = [{i: random.randint(1, 5)} for i in range(30)]
df = pd.DataFrame(x)
df.plot(kind='bar', stacked=True, color=color, legend=False, figsize=(12, 4))

EDIT: yes I agree this is not a correct MVVM approach and I am now using something similar to what is suggested by blindmeis.

One of the way you could to this is

In your Main View Model (where you open the modal):

void OpenModal()
{
    ModalWindowViewModel mwvm = new ModalWindowViewModel();
    Window mw = new Window();
    mw.content = mwvm;
    mw.ShowDialog()
    if(mw.DialogResult == true)
    { 
        // Your Code, you can access property in mwvm if you need.
    }
}

And in your Modal Window View/ViewModel:

XAML:

<Button Name="okButton" Command="{Binding OkCommand}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}">OK</Button>
<Button Margin="2" VerticalAlignment="Center" Name="cancelButton" IsCancel="True">Cancel</Button>

ViewModel:

public ICommand OkCommand
{
    get
    {
        if (_okCommand == null)
        {
            _okCommand = new ActionCommand<Window>(DoOk, CanDoOk);
        }
        return _okCommand ;
    }
}

void DoOk(Window win)
{
    <!--Your Code-->
    win.DialogResult = true;
    win.Close();
}

bool CanDoOk(Window win) { return true; }

or similar to what is posted here WPF MVVM: How to close a window

You should be able to do this by checking the value of $_SERVER['HTTPS'] (it should only be set when using https).

See http://php.net/manual/en/reserved.variables.server.php.

You could try this.

In windows go to Administrative Tools->Services And see scroll down to where it says Oracle[instanceNameHere] and see if the listener and the service itself are running. You might have to start it. You can also set it to start automatically when you right-click on it and go to properties.

If you are using WAMP then type the following in the browser
http://localhost/?phpinfo=-1, you will get the phpinfo page.

phpinfo() from localhost

You can also click the localhost icon in the wamp menu from the systray and then find the phpinfo page. WAMP localhost from WAMP Menu

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.

Usage is simple.

string directoryPath = Path.GetDirectoryName(filePath);

It looks like the SQL Server doesn't have permission to access file C:\backup.bak. I would check the permissions of the account that is assigned to the SQL Server service account.

As part of the solution, you may want to save your backup files to somewhere other that the root of the C: drive. That might be one reason why you are having permission problems.

IDEA has "find action":

Open "Help" menu, type "doc", move cursor to "Quick Documentation" it will be highlighted.

Also "find action" can be called from hot key (you can find it in settings->hotkeys)

There are quite a few potential reasons and - as noted - you need to first diagnose them by setting MSBuild verbosity to 'Diagnostic'. Most of the time the stated reason would be self explanatory and you'd be able to act on it immediatelly, BUT occasionally MSBuild would erroneously claim that some files are modified and need to be copied.

If that is the case, you'd need to either disable NTFS tunneling or duplicate your output folder to a new location. Here it is in more words.

change the sdk version to 21 if its 20 and also make sure the build version as 21.0.1

Try the following:

java -cp jar1:jar2:jar3:dir1:. HelloWorld

The default classpath (unless there is a CLASSPATH environment variable) is the current directory so if you redefine it, make sure you're adding the current directory (.) to the classpath as I have done.

The HTML code is for three div align side by side and can be used for two also by some changes

<div id="wrapper">
  <div id="first">first</div>
  <div id="second">second</div>
  <div id="third">third</div>
</div>

The CSS will be

#wrapper {
  display:table;
  width:100%;
}
#row {
  display:table-row;
}
#first {
  display:table-cell;
  background-color:red;
  width:33%;
}
#second {
  display:table-cell;
  background-color:blue;
  width:33%;
}
#third {
  display:table-cell;
  background-color:#bada55;
  width:34%;
}

This code will workup towards responsive layout as it will resize the

<div> 

according to device width. Even one can silent anyone

<div>

as

<!--<div id="third">third</div> --> 

and can use rest two for two

<div> 

side by side.

I found a little utility function a while back and I've been using it for resetting my form elements ever since (source: http://www.learningjquery.com/2007/08/clearing-form-data):

function clearForm(form) {
  // iterate over all of the inputs for the given form element
  $(':input', form).each(function() {
    var type = this.type;
    var tag = this.tagName.toLowerCase(); // normalize case
    // it's ok to reset the value attr of text inputs, 
    // password inputs, and textareas
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = "";
    // checkboxes and radios need to have their checked state cleared 
    // but should *not* have their 'value' changed
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    // select elements need to have their 'selectedIndex' property set to -1
    // (this works for both single and multiple select elements)
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

... or as a jQuery plugin...

$.fn.clearForm = function() {
  return this.each(function() {
    var type = this.type, tag = this.tagName.toLowerCase();
    if (tag == 'form')
      return $(':input',this).clearForm();
    if (type == 'text' || type == 'password' || tag == 'textarea')
      this.value = '';
    else if (type == 'checkbox' || type == 'radio')
      this.checked = false;
    else if (tag == 'select')
      this.selectedIndex = -1;
  });
};

Simple answer

If you are behind a proxy server, please set the proxy for curl. The curl is not able to connect to server so it shows wrong version number. Set proxy by opening subl ~/.curlrc or use any other text editor. Then add the following line to file: proxy= proxyserver:proxyport For e.g. proxy = 10.8.0.1:8080

If you are not behind a proxy, make sure that the curlrc file does not contain the proxy settings.

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

There is a solution at Paul Welter's Weblog - XML Serializable Generic Dictionary

For some reason, the generic Dictionary in .net 2.0 is not XML serializable. The following code snippet is a xml serializable generic dictionary. The dictionary is serialzable by implementing the IXmlSerializable interface.

The gcc compiler is not in your $PATH. It means either you dont have gcc installed or it's not in your $PATH variable.

To install gcc use this: (run as root)

• Redhat base:

  yum groupinstall "Development Tools"
  

• Debian base:

  apt-get install build-essential
  

I know this is very Old post. Since we don't have any thing sun.misc in maven we can easily use

You should preferably only have your component depend on state and props and it will work as expected, but if you really need a function to force the component to re-render, you could use the useState hook and call the function when needed.

Example

const { useState, useEffect } = React;_x000D_
_x000D_
function Foo() {_x000D_
  const [, forceUpdate] = useState();_x000D_
_x000D_
  useEffect(() => {_x000D_
    setTimeout(forceUpdate, 2000);_x000D_
  }, []);_x000D_
_x000D_
  return <div>{Date.now()}</div>;_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Foo />, document.getElementById("root"));

For a clear understanding, please take a look at my codepen implementations https://codepen.io/serdarsenay/pen/XELWqN

Biggest difference is the need to sort your sample before applying binary search, therefore for most "normal sized" (meaning to be argued) samples will be quicker to search with a linear search algorithm.

Here is the javascript code, for html and css and full running example please refer to above codepen link.

var unsortedhaystack = [];
var haystack = [];
function init() {
  unsortedhaystack = document.getElementById("haystack").value.split(' ');
}
function sortHaystack() {
  var t = timer('sort benchmark');
  haystack = unsortedhaystack.sort();
  t.stop();
}

var timer = function(name) {
    var start = new Date();
    return {
        stop: function() {
            var end  = new Date();
            var time = end.getTime() - start.getTime();
            console.log('Timer:', name, 'finished in', time, 'ms');
        }
    }
};

function lineerSearch() {
  init();
  var t = timer('lineerSearch benchmark');
  var input = this.event.target.value;
  for(var i = 0;i<unsortedhaystack.length - 1;i++) {
    if (unsortedhaystack[i] === input) {
      document.getElementById('result').innerHTML = 'result is... "' + unsortedhaystack[i] + '", on index: ' + i + ' of the unsorted array. Found' + ' within ' + i + ' iterations';
      console.log(document.getElementById('result').innerHTML);
      t.stop(); 
      return unsortedhaystack[i]; 
    }
  }
}

function binarySearch () {
  init();
  sortHaystack();
  var t = timer('binarySearch benchmark');
  var firstIndex = 0;
  var lastIndex = haystack.length-1;
  var input = this.event.target.value;

  //currently point in the half of the array
  var currentIndex = (haystack.length-1)/2 | 0;
  var iterations = 0;

  while (firstIndex <= lastIndex) {
    currentIndex = (firstIndex + lastIndex)/2 | 0;
    iterations++;
    if (haystack[currentIndex]  < input) {

I came up with my own version of the encodeURIComponent, because the posted solution has one problem, if there was a + present in the String, which should be encoded, it will converted to a space.

So here is my class:

import java.io.UnsupportedEncodingException;
import java.util.BitSet;

public final class EscapeUtils
{
    /** used for the encodeURIComponent function */
    private static final BitSet dontNeedEncoding;

    static
    {
        dontNeedEncoding = new BitSet(256);

        // a-z
        for (int i = 97; i <= 122; ++i)
        {
            dontNeedEncoding.set(i);
        }
        // A-Z
        for (int i = 65; i <= 90; ++i)
        {
            dontNeedEncoding.set(i);
        }
        // 0-9
        for (int i = 48; i <= 57; ++i)
        {
            dontNeedEncoding.set(i);
        }

        // '()*
        for (int i = 39; i <= 42; ++i)
        {
            dontNeedEncoding.set(i);
        }
        dontNeedEncoding.set(33); // !
        dontNeedEncoding.set(45); // -
        dontNeedEncoding.set(46); // .

Detecting and embedding Flash within a web document is a surprisingly difficult task.

I was very disappointed with the quality and non-standards compliant markup generated from both SWFObject and Adobe's solutions. Additionally, my testing found Adobe's auto updater to be inconsistent and unreliable.

The JavaScript Flash Detection Library (Flash Detect) and JavaScript Flash HTML Generator Library (Flash TML) are a legible, maintainable and standards compliant markup solution.

You can use a Custom SuccessHandler extending SimpleUrlAuthenticationSuccessHandler for redirecting users to different URLs when login according to their assigned roles.

CustomSuccessHandler class provides custom redirect functionality:

package com.mycompany.uomrmsweb.configuration;

import java.io.IOException;
import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.security.core.Authentication;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.web.DefaultRedirectStrategy;
import org.springframework.security.web.RedirectStrategy;
import org.springframework.security.web.authentication.SimpleUrlAuthenticationSuccessHandler;
import org.springframework.stereotype.Component;

@Component
public class CustomSuccessHandler extends SimpleUrlAuthenticationSuccessHandler{

    private RedirectStrategy redirectStrategy = new DefaultRedirectStrategy();

    @Override
    protected void handle(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException {
        String targetUrl = determineTargetUrl(authentication);

        if (response.isCommitted()) {
            System.out.println("Can't redirect");
            return;
        }

        redirectStrategy.sendRedirect(request, response, targetUrl);
    }

    protected String determineTargetUrl(Authentication authentication) {
        String url="";

        Collection<? extends GrantedAuthority> authorities =  authentication.getAuthorities();

        List<String> roles = new ArrayList<String>();

        for (GrantedAuthority a : authorities) {
            roles.add(a.getAuthority());
        }

        if (isStaff(roles)) {
            url = "/staff";
        } else if (isAdmin(roles)) {
            url = "/admin";
        } else if (isStudent(roles)) {
            url = "/student";
        }else if (isUser(roles)) {
            url = "/home";
        } else {
            url="/Access_Denied";
        }

        return url;
    }

    public void setRedirectStrategy(RedirectStrategy redirectStrategy) {
        this.redirectStrategy = redirectStrategy;
    }
    protected RedirectStrategy getRedirectStrategy() {
        return redirectStrategy;
    }

    private boolean isUser(List<String> roles) {
        if (roles.contains("ROLE_USER")) {
            return true;
        }
        return false;
    }

    private boolean isStudent(List<String> roles) {
        if (roles.contains("ROLE_Student")) {
            return true;
        }
        return false;
    }

    private boolean isAdmin(List<String> roles) {
        if (roles.contains("ROLE_SystemAdmin") || roles.contains("ROLE_ExaminationsStaff")) {
            return true;
        }
        return false;
    }

    private boolean isStaff(List<String> roles) {
        if (roles.contains("ROLE_AcademicStaff") || roles.contains("ROLE_UniversityAdmin")) {
            return true;
        }
        return false;
    }
}

Extending Spring SimpleUrlAuthenticationSuccessHandler class and overriding handle() method which simply invokes a redirect using configured RedirectStrategy [default in this case] with the URL returned by the user defined determineTargetUrl() method. This method extracts the Roles of currently logged in user from Authentication object and then construct appropriate URL based on there roles. Finally RedirectStrategy , which is responsible for all redirections within Spring Security framework , redirects the request to specified URL.

Registering CustomSuccessHandler using SecurityConfiguration class:

package com.mycompany.uomrmsweb.configuration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Autowired
    @Qualifier("customUserDetailsService")
    UserDetailsService userDetailsService;

    @Autowired
    CustomSuccessHandler customSuccessHandler;

    @Autowired
    public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(userDetailsService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
        .antMatchers("/", "/home").access("hasRole('USER')")
        .antMatchers("/admin/**").access("hasRole('SystemAdmin') or hasRole('ExaminationsStaff')")
        .antMatchers("/staff/**").access("hasRole('AcademicStaff') or hasRole('UniversityAdmin')")
        .antMatchers("/student/**").access("hasRole('Student')")  
                    .and().formLogin().loginPage("/login").successHandler(customSuccessHandler)
        .usernameParameter("username").passwordParameter("password")
        .and().csrf()
        .and().exceptionHandling().accessDeniedPage("/Access_Denied");
    }
}

successHandler is the class responsible for eventual redirection based on any custom logic, which in this case will be to redirect the user [to student/admin/staff ] based on his role [USER/Student/SystemAdmin/UniversityAdmin/ExaminationsStaff/AcademicStaff].

Assuming you have referenced and correctly integrated your font to your site (presumably using an @font-face kit) it should be alright to just reference yours the way you do. Presumably it is like this so they have fall backs incase some browsers do not render the fonts correctly

If the attribute you want to sort by is a property, then you can avoid importing operator.attrgetter and use the property's fget method instead.

For example, for a class Circle with a property radius we could sort a list of circles by radii as follows:

result = sorted(circles, key=Circle.radius.fget)

This is not the most well-known feature but often saves me a line with the import.

In my experience, I often encounter the following situations;

1. If you work in a corporate company, contact the network and security team. Because in requests made to external services, it may be necessary to give permission for the relevant endpoint.

2. Another issue is that the SSL certificate may have expired on the server where your application is running.

import json 'mtach' in json.dumps(myDict) is true if found

An easy fix

If you have only one type of collections (e.g. scatter with no error bars) you can also change the colours after that you have plotted them, this sometimes is easier to perform.

import matplotlib.pyplot as plt
from random import randint
import numpy as np

#Let's generate some random X, Y data X = [ [frst group],[second group] ...]
X = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
Y = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
labels = range(1,len(X)+1)

fig = plt.figure()
ax = fig.add_subplot(111)
for x,y,lab in zip(X,Y,labels):
        ax.scatter(x,y,label=lab)

The only piece of code that you need:

#Now this is actually the code that you need, an easy fix your colors just cut and paste not you need ax.
colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired  
colorst = [colormap(i) for i in np.linspace(0, 0.9,len(ax.collections))]       
for t,j1 in enumerate(ax.collections):
    j1.set_color(colorst[t])


ax.legend(fontsize='small')

The output gives you differnent colors even when you have many different scatter plots in the same subplot.

Building on Cheyenne Forbes' answer, and one I found here via fcalderan: Just disable scroll not hide it? and to fix Hallodom's issue of the scrollbar disappearing

CSS:

.preventscroll{
    position: fixed;
    overflow-y:scroll;
}

JS:

whatever.onclick = function(){
    $('body').addClass('preventscroll');
}
whatevertoclose.onclick = function(){
    $('body').removeClass('preventscroll');
}

This code does jump you to the top of the page, but I think that fcalderan's code has a workaround.

the Microsoft XSD inference tool is a good, free solution. Many XML editing tools, such as XmlSpy (mentioned by @Garth Gilmour) or OxygenXML Editor also have that feature. They're rather expensive, though. BizTalk Server also has an XSD inferring tool as well.

edit: I just discovered the .net XmlSchemaInference class, so if you're using .net you should consider that

Wrapping the existing formula in IFERROR will not achieve:

the average of cells that contain non-zero, non-blank values.

I suggest trying:

=if(ArrayFormula(isnumber(K23:M23)),AVERAGEIF(K23:M23,"<>0"),"")

I had the same problem but the problem is not in the framework but in the browser. I don't know why but google chrome blocks cookies automatically, in my case. After allowed cookies the problem was resolved.

This question is almost three years old, but anyway...

If you're using GNU make, this is easy to do. The only problem is that make will interpret non-option arguments in the command line as targets. The solution is to turn them into do-nothing targets, so make won't complain:

# If the first argument is "run"...
ifeq (run,$(firstword $(MAKECMDGOALS)))
  # use the rest as arguments for "run"
  RUN_ARGS := $(wordlist 2,$(words $(MAKECMDGOALS)),$(MAKECMDGOALS))
  # ...and turn them into do-nothing targets
  $(eval $(RUN_ARGS):;@:)
endif

prog: # ...
    # ...

.PHONY: run
run : prog
    @echo prog $(RUN_ARGS)

Running this gives:

$ make run foo bar baz
prog foo bar baz

I just did this (Shadi's first answer) and it works a treat:

    public ActionResult Create()
    {
        Article article = new Article();
        article.Active = true;
        article.DatePublished = DateTime.Now;
        ViewData.Model = article;
        return View();
    } 

I could put the default values in my model like a propper MVC addict: (I'm using Entity Framework)

    public partial class Article
    {
        public Article()
        {
            Active = true;
            DatePublished = Datetime.Now;
        }
    }

    public ActionResult Create()
    {
        Article article = new Article();
        ViewData.Model = article;
        return View();
    } 

Can anyone see any downsides to this?

Close all the visual studio instances and try again. It worked for me :)

Now, back to your questions:

Q1. Does this sequence generator make use of the database's increasing numeric value generating capability or generates the number on its own?

By using the GenerationType.SEQUENCE strategy on the @GeneratedValue annotation, the JPA provider will try to use a database sequence object of the underlying database that supports this feature (e.g., Oracle, SQL Server, PostgreSQL, MariaDB).

If you are using MySQL, which doesn't support database sequence objects, then Hibernate is going to fall back to using the GenerationType.TABLE instead, which is undesirable since the TABLE generation performs badly.

So, don't use the GenerationType.SEQUENCE strategy with MySQL.

Q2. If JPA uses a database auto-increment feature, then will it work with datastores that don't have auto-increment feature?

I assume you are talking about the GenerationType.IDENTITY when you say database auto-increment feature.

To use an AUTO_INCREMENT or IDENTITY column, you need to use the GenerationType.IDENTITYstrategy on the @GeneratedValue annotation.

Q3. If JPA generates numeric value on its own, then how does the JPA implementation know which value to generate next? Does it consult with the database first to see what value was stored last in order to generate the value (last + 1)?

The only time when the JPA provider generates values on its own is when you are using the sequence-based optimizers, like:

• hi/lo
• pooled or pooled-lo

These optimizers are meat to reduce the number of database sequence calls, so they multiply the number of identifier values that can be generated using a single database sequence call.

To avoid conflicts between Hibernate identifier optimizers and other 3rd-party clients, you should use pooled or pooled-lo instead of hi/lo. Even if you are using a legacy application that was designed to use hi/lo, you can migrate to the pooled or pooled-lo optimizers.

Q4. Please also shed some light on sequenceName and allocationSize properties of @SequenceGenerator annotation.

The sequenceName attribute defines the database sequence object to be used to generate the identifier values. IT's the object you created using the CREATE SEQUENCE DDL statement.

So, if you provide this mapping:

@Id
@GeneratedValue(
    strategy = GenerationType.SEQUENCE,
    generator = "seq_post"
)
@SequenceGenerator(
    name = "seq_post"
)
private Long id;

Hibernate is going to use the seq_post database object to generate the identifier values:

SELECT nextval('hibernate_sequence')

The allocationSize defines the identifier value multiplier, and if you provide a value that's greater than 1, then Hibernate is going to use the pooled optimizer, to reduce the number of database sequence calls.

So, if you provide this mapping:

@Id
@GeneratedValue(
    strategy = GenerationType.SEQUENCE,
    generator = "seq_post"
)
@SequenceGenerator(
    name = "seq_post",
    allocationSize = 5
)
private Long id;

Then, when you persist 5 entities:

for (int i = 1; i <= 5; i++) {
    entityManager.persist(
        new Post().setTitle(
            String.format(
                "High-Performance Java Persistence, Part %d",
                i
            )
        )
    );
}

Only 2 database sequence calls will be executed, instead of 5:

SELECT nextval('hibernate_sequence')
SELECT nextval('hibernate_sequence')
 
INSERT INTO post (title, id)
VALUES ('High-Performance Java Persistence, Part 1', 1)
 
INSERT INTO post (title, id)
VALUES ('High-Performance Java Persistence, Part 2', 2)
 
INSERT INTO post (title, id)
VALUES ('High-Performance Java Persistence, Part 3', 3)
 
INSERT INTO post (title, id)
VALUES ('High-Performance Java Persistence, Part 4', 4)
 
INSERT INTO post (title, id)
VALUES ('High-Performance Java Persistence, Part 5', 5)

The closest I can get to this is this example:

http://jsfiddle.net/YRFJQ/1/

or

.container {  
  background: blue; 
  border: 10px solid blue; 
  max-height: 200px; 
  max-width: 200px; 
  overflow:hidden;
  box-sizing:border-box;
}

img { 
  display: block;
  max-height: 100%; 
  max-width: 100%; 
}

The main problem is that the height takes the percentage of the containers height, so it is looking for an explicitly set height in the parent container, not it's max-height.

The only way round this to some extent I can see is the fiddle above where you can hide the overflow, but then the padding still acts as visible space for the image to flow into, and so replacing with a solid border works instead (and then adding border-box to make it 200px if that's the width you need)

Not sure if this would fit with what you need it for, but the best I can seem to get to.

I've also been successful with this URL structure:

        }
    });
</script>

You can use the TryParse method that returns true if it successful:

Age age;

if(Enum.TryParse<Age>("myString", out age))
{
   //Here you can use age
}

Well, what about something like this:

PS3="Select database or <Q> to quit: "
select DB in db1 db2 db3; do
   [ "${REPLY^*}" = 'Q' ] && break
   echo "Should backup $DB..."
done

Suppose we have column with alphanumeric field having entries like

a41q
1458
xwe8
1475
asde
9582
.
.
.
.
.
qe84

and you want highest numeric value from this db column (in this case it is 9582) then this query will help you

SELECT Max(column_name) from table_name where column_name REGEXP '^[0-9]+$'

Simply add class="img-responsive" to the video tag. I'm doing this on a current project, and it works. It doesn't need to be wrapped in anything.

<video class="img-responsive" src="file.mp4" autoplay loop/>

Below would be the best way to insert a row into pandas dataframe without sorting and reseting an index:

import pandas as pd

df = pd.DataFrame(columns=['a','b','c'])

def insert(df, row):
    insert_loc = df.index.max()

    if pd.isna(insert_loc):
        df.loc[0] = row
    else:
        df.loc[insert_loc + 1] = row

insert(df,[2,3,4])
insert(df,[8,9,0])
print(df)

A much simpler solution:

<script language="javascript" src="http://maps.google.com/maps/api/js?v=3.2&sensor=false"></script>

and later in the code:

var online;
// check whether this function works (online only)
try {
  var x = google.maps.MapTypeId.TERRAIN;
  online = true;
} catch (e) {
  online = false;
}
console.log(online);

When not online the google script will not be loaded thus resulting in an error where an exception will be thrown.

    import os
    import ftplib
    from contextlib import closing

    with closing(ftplib.FTP()) as ftp:
        try:
            ftp.connect(host, port, 30*5) #5 mins timeout
            ftp.login(login, passwd)
            ftp.set_pasv(True)
            with open(local_filename, 'w+b') as f:
                res = ftp.retrbinary('RETR %s' % orig_filename, f.write)

                if not res.startswith('226 Transfer complete'):
                    print('Downloaded of file {0} is not compile.'.format(orig_filename))
                    os.remove(local_filename)
                    return None

            return local_filename

        except:
                print('Error during download from FTP')

It can be done like this

(function(X, Y) {_x000D_
  _x000D_
  // X is the local name of the 'class'_x000D_
  // Doo is default value if param X is empty_x000D_
  var X = (typeof X == 'string') ? X: 'Doo';_x000D_
  var Y = (typeof Y == 'string') ? Y: 'doo';_x000D_
  _x000D_
  // this refers to the local X defined above_x000D_
  this[X] = function(doo) {_x000D_
    // object variable_x000D_
    this.doo = doo || 'doo it';_x000D_
  }_x000D_
  // prototypal inheritance for methods_x000D_
  // defined by another_x000D_
  this[X].prototype[Y] = function() {_x000D_
    return this.doo || 'doo';_x000D_
  };_x000D_
  _x000D_
  // make X global_x000D_
  window[X] = this[X];_x000D_
}('Dooa', 'dooa')); // give the names here_x000D_
_x000D_
// test_x000D_
doo = new Dooa('abc');_x000D_
doo2 = new Dooa('def');_x000D_
console.log(doo.dooa());_x000D_
console.log(doo2.dooa());

You could use Series.reindex:

import pandas as pd

idx = pd.date_range('09-01-2013', '09-30-2013')

s = pd.Series({'09-02-2013': 2,
               '09-03-2013': 10,
               '09-06-2013': 5,
               '09-07-2013': 1})
s.index = pd.DatetimeIndex(s.index)

s = s.reindex(idx, fill_value=0)
print(s)

yields

2013-09-01     0
2013-09-02     2
2013-09-03    10
2013-09-04     0
2013-09-05     0
2013-09-06     5

The base-class constructor is already automatically called by your derived-class constructor. In C++, if the base class has a default constructor (takes no arguments, can be auto-generated by the compiler!), and the derived-class constructor does not invoke another base-class constructor in its initialisation list, the default constructor will be called. I.e. your code is equivalent to:

class PetStore: public Farm
{
public :
    PetStore()
    : Farm()     // <---- Call base-class constructor in initialision list
    {
     idF=0;
    };
private:
    int idF;
    string nameF;
}

def trim(x):
    if x.dtype == object:
        x = x.str.split(' ').str[0]
    return(x)

df = df.apply(trim)

You must use log4j.configuration property like this:

java -Dlog4j.configuration=file:/path/to/log4j.properties myApp

If the file is under the class-path (inside ./src/main/resources/ folder), you can omit the file:// protocol:

java -Dlog4j.configuration=path/to/log4j.properties myApp

I find this method saves a lot of typing, and prevents a lot of typos.

string nl = "\r\n";

txtOutput.Text = "First line" + nl + "Second line" + nl + "Third line";

Looks like the solution in the question doesn't work with Django 1.7 anymore and raises an error: "Cannot reorder a query once a slice has been taken"

According to the documentation https://docs.djangoproject.com/en/dev/topics/db/queries/#limiting-querysets forcing the “step” parameter of Python slice syntax evaluates the Query. It works this way:

Model.objects.all().order_by('-id')[:10:1]

Still I wonder if the limit is executed in SQL or Python slices the whole result array returned. There is no good to retrieve huge lists to application memory.

. is a shorthand for the current directory and is used in Linux and Unix to execute a compiled program in the current directory. That is why you don't see this used in Web Development much except by open source, non-Windows frameworks like Google Angular which was written by people stuck on open source platforms.

./ also resolves to the current directory and is atypical in Web but supported as a path in some open source frameworks. Because it resolves the same as no path to the current file directory its not used. Example: ./image.jpg = image.jpg. Again, this is a relic of Unix operating systems that need path resolutions like this to run executables and resolve paths for security reasons. Its not a typical web path. That is why this syntax is redundant.

../ is a traditional web path that goes one directory up

/ is the ROOT of your website

These path resolutions below are true...

./folder= folder this is always true in web path resolution

./file.html = file.html this is always true in web path resolution

./ = {no path} an empty path is the same as ./ in the web world

{no path} = / an empty path is the same as the web root if your file is in the root directory

./ = / ONLY if you are in the root folder

../ = / ONLY if you are one folder below the web root

You can do it that way:

• Create a directory where you want to install composer (let's say /home/your_username/composer)
• Go to this directory - cd /home/your_username/composer

• Then run the following command:

  php -r "readfile('https://getcomposer.org/installer');" | php

• After that if you want to run composer, you can do it this way (in this caseyou must be in the composer's dir): php composer.phar

• As a next step, you can do this:

  alias composer="/home/your_username/composer/composer.phar".

  And run commands like you do it normally: $ composer install

Hope that helps

Use assets like a filesystem to dump any kind of files. And use res to store what it is made for, layouts, images, values.

You are using the wrong build.gradle file.

In your top-level file you can't define an android block.

Just move this part inside the module/build.gradle file.

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

A char doesn't have any methods - it's a Java primitive. You're looking for the Character wrapper class.

The usage would be:

if(Character.isLetter(ch)) { //... }

try this:

public int getRandomNumber(int min, int max) {
    return (int) Math.floor(Math.random() * (max - min + 1)) + min;
}

SQL is not faithful to the relational model in many ways. The result of a SQL query is not a relation because it may have columns with duplicate names, 'anonymous' (unnamed) columns, duplicate rows, nulls, etc. SQL doesn't treat tables as relations because it relies on column ordering etc.

The idea behind NATURAL JOIN in SQL is to make it easier to be more faithful to the relational model. The result of the NATURAL JOIN of two tables will have columns de-duplicated by name, hence no anonymous columns. Similarly, UNION CORRESPONDING and EXCEPT CORRESPONDING are provided to address SQL's dependence on column ordering in the legacy UNION syntax.

However, as with all programming techniques it requires discipline to be useful. One requirement for a successful NATURAL JOIN is consistently named columns, because joins are implied on columns with the same names (it is a shame that the syntax for renaming columns in SQL is verbose but the side effect is to encourage discipline when naming columns in base tables and VIEWs :)

Note a SQL NATURAL JOIN is an equi-join**, however this is no bar to usefulness. Consider that if NATURAL JOIN was the only join type supported in SQL it would still be relationally complete.

While it is indeed true that any NATURAL JOIN may be written using INNER JOIN and projection (SELECT), it is also true that any INNER JOIN may be written using product (CROSS JOIN) and restriction (WHERE); further note that a NATURAL JOIN between tables with no column names in common will give the same result as CROSS JOIN. So if you are only interested in results that are relations (and why ever not?!) then NATURAL JOIN is the only join type you need. Sure, it is true that from a language design perspective shorthands such as INNER JOIN and CROSS JOIN have their value, but also consider that almost any SQL query can be written in 10 syntactically different, but semantically equivalent, ways and this is what makes SQL optimizers so very hard to develop.

Here are some example queries (using the usual parts and suppliers database) that are semantically equivalent:

SELECT *
  FROM S NATURAL JOIN SP;

-- Must disambiguate and 'project away' duplicate SNO attribute
SELECT S.SNO, SNAME, STATUS, CITY, PNO, QTY
  FROM S INNER JOIN SP 
          USING (SNO);                        

-- Alternative projection
SELECT S.*, PNO, QTY
  FROM S INNER JOIN SP 
          ON S.SNO = SP.SNO;

-- Same columns, different order == equivalent?!
SELECT SP.*, S.SNAME, S.STATUS, S.CITY
  FROM S INNER JOIN SP 
      ON S.SNO = SP.SNO;

-- 'Old school'
SELECT S.*, PNO, QTY
  FROM S, SP 
 WHERE S.SNO = SP.SNO;

** Relational natural join is not an equijoin, it is a projection of one. – philipxy

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

The message you mention is quite clear:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

SLF4J API could not find a binding, and decided to default to a NOP implementation. In your case slf4j-log4j12.jar was somehow not visible when the LoggerFactory class was loaded into memory, which is admittedly very strange. What does "mvn dependency:tree" tell you?

The various dependency declarations may not even be directly at cause here. I strongly suspect that a pre-1.6 version of slf4j-api.jar is being deployed without your knowledge.

Use the files filelist of the element instead of val()

$("input[type=file]").on('change',function(){
    alert(this.files[0].name);
});

You can call a JavaScript function and use window.location = 'url';:

http://www.pageresource.com/jscript/jredir.htm

javascript has the sort function which can take another function as parameter - that second function is used to compare two elements.

Example:

cars = [

    {
        name: "Honda",
        speed: 80
    },

    {
        name: "BMW",
        speed: 180
    },

    {
        name: "Trabi",
        speed: 40
    },

    {
        name: "Ferrari",
        speed: 200
    }
]


cars.sort(function(a, b) { 
    return a.speed - b.speed;
})

for(var i in cars)
    document.writeln(cars[i].name) // Trabi Honda BMW Ferrari 

ok, from your comment i see that you're using the word 'sort' in a wrong sense. In programming "sort" means "put things in a certain order", not "arrange things in groups". The latter is much simpler - this is just how you "sort" things in the real world

• make two empty arrays ("boxes")
• for each object in your list, check if it matches the criteria
• if yes, put it in the first "box"
• if no, put it in the second "box"

You need to type result to an array of string const result: string[] = [];.

You need to provide a candidate for autowire. That means that an instance of PasswordHint must be known to spring in a way that it can guess that it must reference it.

Please provide the class head of PasswordHint and/or the spring bean definition of that class for further assistance.

Try changing the name of

PasswordHintAction action;

to

PasswordHintAction passwordHintAction;

so that it matches the bean definition.

I encountered the same problem. This solution allows me to keep using the generic login view:

    (r'^accounts/profile/$', 'redirect_to', {'url': 'generic_account_url'}),
)

You should check your project facets in the project configuration. This is where you may uncheck the JSF dependency.

Also, when you uninstall the package, the first item listed is the directory to the executable.

It looks as if you were on the right track. You just need to add the else statement after the ";" following the "then" statement. Also I would split the first line from the second line with a semicolon instead of joining it with "&&".

maxline='cat journald.conf | grep "#SystemMaxUse="'; if [ $maxline == "#SystemMaxUse=" ]; then sed 's/\#SystemMaxUse=/SystemMaxUse=50M/g' journald.conf > journald.conf2 && mv journald.conf2 journald.conf; else echo "This file has been edited. You'll need to do it manually."; fi

Also in your original script, when declaring maxline you used back-ticks "`" instead of single quotes "'" which might cause problems.

if (position ==0) {
    if (rYes.isChecked()) {
        Toast.makeText(SportActivity.this, "yes ur answer is right", Toast.LENGTH_LONG).show();
    } else if (rNo.isChecked()) {
        Toast.makeText(SportActivity.this, "no.ur answer is wrong", Toast.LENGTH_LONG).show();
    }
}

This code is supposed to select both check boxes.
Is there a problem with it?

I was also having this same problem. I developed a synchronous solution thanks to the research done by @tpeczek in the following SO article: Unable to authenticate to ASP.NET Web Api service with HttpClient

My solution uses a WebClient, which as you correctly noted passes the credentials without issue. The reason HttpClient doesn't work is because of Windows security disabling the ability to create new threads under an impersonated account (see SO article above.) HttpClient creates new threads via the Task Factory thus causing the error. WebClient on the other hand, runs synchronously on the same thread thereby bypassing the rule and forwarding its credentials.

Although the code works, the downside is that it will not work async.

var wi = (System.Security.Principal.WindowsIdentity)HttpContext.Current.User.Identity;

var wic = wi.Impersonate();
try
{
    var data = JsonConvert.SerializeObject(new
    {
        Property1 = 1,
        Property2 = "blah"
    });

    using (var client = new WebClient { UseDefaultCredentials = true })
    {
        client.Headers.Add(HttpRequestHeader.ContentType, "application/json; charset=utf-8");
        client.UploadData("http://url/api/controller", "POST", Encoding.UTF8.GetBytes(data));
    }
}
catch (Exception exc)
{
    // handle exception
}
finally
{
    wic.Undo();
}

Note: Requires NuGet package: Newtonsoft.Json, which is the same JSON serializer WebAPI uses.

Another possibility can be connection reset from the TCP wrappers (/etc/hosts.deny and /etc/hosts.allow). Just check what is coming in from the telnet to port 3306 - if it is nothing, then there is something is in the middle preventing communication from happening.

Ok, at that time got it done with the help of a friend and the code looks like this.

Sub Saving()

Dim part1 As String

Dim part2 As String


part1 = Range("C5").Value

part2 = Range("C8").Value


ActiveWorkbook.SaveAs Filename:= _

"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False

End Sub

How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou

Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

This is a comprehensive answer to this question. I have done this because this page is high on the Google search results and the answer does not go into enough detail. This post assumes that you are competent at using Visual Studio C# forms. This is based on VS2012.

1. Start by simply dragging a ContextMenuStrip onto the form. It will just put it into the top left corner where you can add your menu items and rename it as you see fit.

2. You will have to view code and enter in an event yourself on the form. Create a mouse down event for the item in question and then assign a right click event for it like so (I have called the ContextMenuStrip "rightClickMenuStrip"):

   private void pictureBox1_MouseDown(object sender, MouseEventArgs e)
   {
   switch (e.Button)
       {
           case MouseButtons.Right:
           {
               rightClickMenuStrip.Show(this, new Point(e.X, e.Y));//places the menu at the pointer position
           }
           break;
       }
   }
   

3. Assign the event handler manually to the form.designer (you may need to add a "using" for System.Windows.Forms; You can just resolve it):

   this.pictureBox1.MouseDown += new MouseEventHandler(this.pictureBox1_MouseDown);
   

4. All that is needed at this point is to simply double click each menu item and do the desired operations for each click event in the same way you would for any other button.

This is the basic code for this operation. You can obviously modify it to fit in with your coding practices.

SWIFT 4

In Swift 4 you can use GCDs dispatch queues to lock resources.

class MyObject {
    private var internalState: Int = 0
    private let internalQueue: DispatchQueue = DispatchQueue(label:"LockingQueue") // Serial by default

    var state: Int {
        get {
            return internalQueue.sync { internalState }
        }

        set (newState) {
            internalQueue.sync { internalState = newState }
        }
    }
} 

Since no-one has yet wrote a function to do this with two integers, here's one way:

private long CalculatePower(int number, int powerOf)
{
    for (int i = powerOf; i > 1; i--)
        number *= number;
    return number;
}
CalculatePower(5, 3); // 125
CalculatePower(8, 4); // 4096
CalculatePower(6, 2); // 36

Alternatively in VB.NET:

Private Function CalculatePower(number As Integer, powerOf As Integer) As Long
    For i As Integer = powerOf To 2 Step -1
        number *= number
    Next
    Return number
End Function
CalculatePower(5, 3) ' 125
CalculatePower(8, 4) ' 4096
CalculatePower(6, 2) ' 36

You have to cast simpleXML Object to a string.

$value = (string) $xml->code[0]->lat;

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

If you want to count the number of instances of strings with more than a single character, you can either use the previous solution with regex, or this solution uses STRING_SPLIT, which I believe was introduced in SQL Server 2016. Also you’ll need compatibility level 130 and higher.

ALTER DATABASE [database_name] SET COMPATIBILITY_LEVEL = 130

.

--some data
DECLARE @table TABLE (col varchar(500))
INSERT INTO @table SELECT 'whaCHAR(10)teverCHAR(10)whateverCHAR(10)'
INSERT INTO @table SELECT 'whaCHAR(10)teverwhateverCHAR(10)'
INSERT INTO @table SELECT 'whaCHAR(10)teverCHAR(10)whateverCHAR(10)~'

--string to find
DECLARE @string varchar(100) = 'CHAR(10)'

--select
SELECT 
    col
  , (SELECT COUNT(*) - 1 FROM STRING_SPLIT (REPLACE(REPLACE(col, '~', ''), 'CHAR(10)', '~'), '~')) AS 'NumberOfBreaks'
FROM @table

To answer your question, firstly I would strongly recommend looking at the Documentation.

Without overriding the equals() method, it will act like "==". When you use the "==" operator on objects, it simply checks to see if those pointers refer to the same object. Not if their members contain the same value.

We override to keep our code clean, and abstract the comparison logic from the If statement, into the object. This is considered good practice and takes advantage of Java's heavily Object Oriented Approach.

I use this:

function fnIsAppleMobile() 
{
    if (navigator && navigator.userAgent && navigator.userAgent != null) 
    {
        var strUserAgent = navigator.userAgent.toLowerCase();
        var arrMatches = strUserAgent.match(/(iphone|ipod|ipad)/);
        if (arrMatches != null) 
             return true;
    } // End if (navigator && navigator.userAgent) 

    return false;
} // End Function fnIsAppleMobile


var bIsAppleMobile = fnIsAppleMobile(); // TODO: Write complaint to CrApple asking them why they don't update SquirrelFish with bugfixes, then remove

.textbox {
    height: 40px;
}

<div id=signin>  
    <input type="text" class="textbox" size="25%" height="50"/></br>
<input type="text" class="textbox" size="25%" height="50"/>

Make the font size larger and add height (or line height to the input boxes) I would not recommend adding those size and height attributes in the HTML as that can be handled by CSS. I have made a class text-box that can be used for multiple input boxes

Simplest of them all is to use the "Flash Fill" option under the "Data" tab.

1. Keep the original input column on the left (say column A) and just add a blank column on the right of it (say column B, this new column will be treated as output).

2. Just fill in a couple of cells of Column B with actual expected output. In this case:

         [email protected],
         [email protected],
   

3. Then select the column range where you want the output along with the first couple of cells you filled manually ... then do the magic...click on "Flash Fill".

It basically understands the output pattern corresponding to the input and fills the empty cells.

OUTDATED - see this answer for a simpler approach

To obtain readable x tick labels without additional dependencies, you want to use:

  ... +
  theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5)) +
  ...

This rotates the tick labels 90° counterclockwise and aligns them vertically at their end (hjust = 1) and their centers horizontally with the corresponding tick mark (vjust = 0.5).

Full example:

library(ggplot2)
data(diamonds)
diamonds$cut <- paste("Super Dee-Duper",as.character(diamonds$cut))
q <- qplot(cut,carat,data=diamonds,geom="boxplot")
q + theme(axis.text.x = element_text(angle = 90, hjust = 1, vjust = 0.5))

Note, that vertical/horizontal justification parameters vjust/hjust of element_text are relative to the text. Therefore, vjust is responsible for the horizontal alignment.

Without vjust = 0.5 it would look like this:

q + theme(axis.text.x = element_text(angle = 90, hjust = 1))

Without hjust = 1 it would look like this:

q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5))

If for some (wired) reason you wanted to rotate the tick labels 90° clockwise (such that they can be read from the left) you would need to use: q + theme(axis.text.x = element_text(angle = -90, vjust = 0.5, hjust = -1)).

All of this has already been discussed in the comments of this answer but I come back to this question so often, that I want an answer from which I can just copy without reading the comments.

You could use ol' good easy_install zipline instead.

easy_install isn't pip but one good aspect of it is the ability to download and install binary packages too, which would free you for the need having VC++ ready. This of course relies of the assumption that the binaries were prepared for your Python version.

UPDATE:

Yes, Pip can install binaries now!

There's a new binary Python archive format (wheel) that is supposed to replace "eggs". Wheels are already supported by pip. This means you'll be able to install zipline with pip without compiling it as soon as someone builds the wheel for your platform and uploads it to PyPI.

One solution is doing the sum:

=SUM(COUNTIFS(A1:A196,{"yes","no"},B1:B196,"agree"))

or know its not the countifs but the sumproduct will do it in one line:

=SUMPRODUCT(((A1:A196={"yes","no"})*(j1:j196="agree")))

In my case (Rails 5), I ended up adding these 2 lines in my app/config/environments/development.rb

config.time_zone = "Melbourne"
config.active_record.default_timezone = :local

That's it! And to make sure that Melbourne was read correctly, I ran the command in my terminal:

bundle exec rake time:zones:all

and Melbourne was listing in the timezone I'm in!

Here is the correct solution that actually has cross-browser support:

  br {
        line-height: 150%;
     }

This is a modern Promise version of the previous one, using a Promise.all approach to resolve all promises when all files have been read:

/**
 * Promise all
 * @author Loreto Parisi (loretoparisi at gmail dot com)
 */
function promiseAllP(items, block) {
    var promises = [];
    items.forEach(function(item,index) {
        promises.push( function(item,i) {
            return new Promise(function(resolve, reject) {
                return block.apply(this,[item,index,resolve,reject]);
            });
        }(item,index))
    });
    return Promise.all(promises);
} //promiseAll

/**
 * read files
 * @param dirname string
 * @return Promise
 * @author Loreto Parisi (loretoparisi at gmail dot com)
 * @see http://stackoverflow.com/questions/10049557/reading-all-files-in-a-directory-store-them-in-objects-and-send-the-object
 */
function readFiles(dirname) {
    return new Promise((resolve, reject) => {
        fs.readdir(dirname, function(err, filenames) {
            if (err) return reject(err);
            promiseAllP(filenames,
            (filename,index,resolve,reject) =>  {
                fs.readFile(path.resolve(dirname, filename), 'utf-8', function(err, content) {
                    if (err) return reject(err);
                    return resolve({filename: filename, contents: content});
                });
            })
            .then(results => {
                return resolve(results);
            })
            .catch(error => {
                return reject(error);
            });
        });
  });
}

How to Use It:

Just as simple as doing:

readFiles( EMAIL_ROOT + '/' + folder)
.then(files => {
    console.log( "loaded ", files.length );
    files.forEach( (item, index) => {
        console.log( "item",index, "size ", item.contents.length);
    });
})
.catch( error => {
    console.log( error );
});

Supposed that you have another list of folders you can as well iterate over this list, since the internal promise.all will resolve each of then asynchronously:

var folders=['spam','ham'];
folders.forEach( folder => {
    readFiles( EMAIL_ROOT + '/' + folder)
    .then(files => {
        console.log( "loaded ", files.length );
        files.forEach( (item, index) => {
            console.log( "item",index, "size ", item.contents.length);
        });
    })
    .catch( error => {
        console.log( error );
    });
});

How it Works

The promiseAll does the magic. It takes a function block of signature function(item,index,resolve,reject), where item is the current item in the array, index its position in the array, and resolve and reject the Promise callback functions. Each promise will be pushed in a array at the current index and with the current item as arguments through a anonymous function call:

promises.push( function(item,i) {
        return new Promise(function(resolve, reject) {
            return block.apply(this,[item,index,resolve,reject]);
        });
    }(item,index))

Then all promises will be resolved:

return Promise.all(promises);

All you need to do is use getCheckedRadioButtonId() and isChecked() method,

if(gender.getCheckedRadioButtonId()==-1)
{
    Toast.makeText(getApplicationContext(), "Please select Gender", Toast.LENGTH_SHORT).show();
}
else
{
    // get selected radio button from radioGroup
    int selectedId = gender.getCheckedRadioButtonId();
    // find the radiobutton by returned id
    selectedRadioButton = (RadioButton)findViewById(selectedId);
    Toast.makeText(getApplicationContext(), selectedRadioButton.getText().toString()+" is selected", Toast.LENGTH_SHORT).show();
}

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

Given say...

std::string x = "hello";

Getting a `char *` or `const char*` from a `string`

How to get a character pointer that's valid while x remains in scope and isn't modified further

C++11 simplifies things; the following all give access to the same internal string buffer:

const char* p_c_str = x.c_str();
const char* p_data  = x.data();
char* p_writable_data = x.data(); // for non-const x from C++17 
const char* p_x0    = &x[0];

      char* p_x0_rw = &x[0];  // compiles iff x is not const...

All the above pointers will hold the same value - the address of the first character in the buffer. Even an empty string has a "first character in the buffer", because C++11 guarantees to always keep an extra NUL/0 terminator character after the explicitly assigned string content (e.g. std::string("this\0that", 9) will have a buffer holding "this\0that\0").

Given any of the above pointers:

char c = p[n];   // valid for n <= x.size()
                 // i.e. you can safely read the NUL at p[x.size()]

Only for the non-const pointer p_writable_data and from &x[0]:

p_writable_data[n] = c;
p_x0_rw[n] = c;  // valid for n <= x.size() - 1
                 // i.e. don't overwrite the implementation maintained NUL

Writing a NUL elsewhere in the string does not change the string's size(); string's are allowed to contain any number of NULs - they are given no special treatment by std::string (same in C++03).

In C++03, things were considerably more complicated (key differences highlighted):

• x.data()

  • returns const char* to the string's internal buffer which wasn't required by the Standard to conclude with a NUL (i.e. might be ['h', 'e', 'l', 'l', 'o'] followed by uninitialised or garbage values, with accidental accesses thereto having undefined behaviour).
    • x.size() characters are safe to read, i.e. x[0] through x[x.size() - 1]
    • for empty strings, you're guaranteed some non-NULL pointer to which 0 can be safely added (hurray!), but you shouldn't dereference that pointer.

• &x[0]

  • for empty strings this has undefined behaviour (21.3.4)
    • e.g. given f(const char* p, size_t n) { if (n == 0) return; ...whatever... } you mustn't call f(&x[0], x.size()); when x.empty() - just use f(x.data(), ...).
  • otherwise, as per x.data() but:
    • for non-const x this yields a non-const char* pointer; you can overwrite string content

• x.c_str()

  • returns const char* to an ASCIIZ (NUL-terminated) representation of the value (i.e. ['h', 'e', 'l', 'l', 'o', '\0']).
  • although few if any implementations chose to do so, the C++03 Standard was worded to allow the string implementation the freedom to create a distinct NUL-terminated buffer on the fly, from the potentially non-NUL terminated buffer "exposed" by x.data() and &x[0]
  • x.size() + 1 characters are safe to read.
  • guaranteed safe even for empty strings (['\0']).

Consequences of accessing outside legal indices

Whichever way you get a pointer, you must not access memory further along from the pointer than the characters guaranteed present in the descriptions above. Attempts to do so have undefined behaviour, with a very real chance of application crashes and garbage results even for reads, and additionally wholesale data, stack corruption and/or security vulnerabilities for writes.

When do those pointers get invalidated?

If you call some string member function that modifies the string or reserves further capacity, any pointer values returned beforehand by any of the above methods are invalidated. You can use those methods again to get another pointer. (The rules are the same as for iterators into strings).

See also How to get a character pointer valid even after x leaves scope or is modified further below....

So, which is better to use?

From C++11, use .c_str() for ASCIIZ data, and .data() for "binary" data (explained further below).

In C++03, use .c_str() unless certain that .data() is adequate, and prefer .data() over &x[0] as it's safe for empty strings....

...try to understand the program enough to use data() when appropriate, or you'll probably make other mistakes...

The ASCII NUL '\0' character guaranteed by .c_str() is used by many functions as a sentinel value denoting the end of relevant and safe-to-access data. This applies to both C++-only functions like say fstream::fstream(const char* filename, ...) and shared-with-C functions like strchr(), and printf().

Given C++03's .c_str()'s guarantees about the returned buffer are a super-set of .data()'s, you can always safely use .c_str(), but people sometimes don't because:

• using .data() communicates to other programmers reading the source code that the data is not ASCIIZ (rather, you're using the string to store a block of data (which sometimes isn't even really textual)), or that you're passing it to another function that treats it as a block of "binary" data. This can be a crucial insight in ensuring that other programmers' code changes continue to handle the data properly.
• C++03 only: there's a slight chance that your string implementation will need to do some extra memory allocation and/or data copying in order to prepare the NUL terminated buffer

As a further hint, if a function's parameters require the (const) char* but don't insist on getting x.size(), the function probably needs an ASCIIZ input, so .c_str() is a good choice (the function needs to know where the text terminates somehow, so if it's not a separate parameter it can only be a convention like a length-prefix or sentinel or some fixed expected length).

How to get a character pointer valid even after x leaves scope or is modified further

You'll need to copy the contents of the string x to a new memory area outside x. This external buffer could be in many places such as another string or character array variable, it may or may not have a different lifetime than x due to being in a different scope (e.g. namespace, global, static, heap, shared memory, memory mapped file).

To copy the text from std::string x into an independent character array:

// USING ANOTHER STRING - AUTO MEMORY MANAGEMENT, EXCEPTION SAFE
std::string old_x = x;
// - old_x will not be affected by subsequent modifications to x...
// - you can use `&old_x[0]` to get a writable char* to old_x's textual content
// - you can use resize() to reduce/expand the string
//   - resizing isn't possible from within a function passed only the char* address

std::string old_x = x.c_str(); // old_x will terminate early if x embeds NUL
// Copies ASCIIZ data but could be less efficient as it needs to scan memory to
// find the NUL terminator indicating string length before allocating that amount
// of memory to copy into, or more efficient if it ends up allocating/copying a
// lot less content.
// Example, x == "ab\0cd" -> old_x == "ab".

// USING A VECTOR OF CHAR - AUTO, EXCEPTION SAFE, HINTS AT BINARY CONTENT, GUARANTEED CONTIGUOUS EVEN IN C++03
std::vector<char> old_x(x.data(), x.data() + x.size());       // without the NUL
std::vector<char> old_x(x.c_str(), x.c_str() + x.size() + 1);  // with the NUL

// USING STACK WHERE MAXIMUM SIZE OF x IS KNOWN TO BE COMPILE-TIME CONSTANT "N"
// (a bit dangerous, as "known" things are sometimes wrong and often become wrong)
char y[N + 1];
strcpy(y, x.c_str());

// USING STACK WHERE UNEXPECTEDLY LONG x IS TRUNCATED (e.g. Hello\0->Hel\0)
char y[N + 1];
strncpy(y, x.c_str(), N);  // copy at most N, zero-padding if shorter
y[N] = '\0';               // ensure NUL terminated

// USING THE STACK TO HANDLE x OF UNKNOWN (BUT SANE) LENGTH
char* y = alloca(x.size() + 1);
strcpy(y, x.c_str());

// USING THE STACK TO HANDLE x OF UNKNOWN LENGTH (NON-STANDARD GCC EXTENSION)
char y[x.size() + 1];
strcpy(y, x.c_str());

// USING new/delete HEAP MEMORY, MANUAL DEALLOC, NO INHERENT EXCEPTION SAFETY
char* y = new char[x.size() + 1];
strcpy(y, x.c_str());
//     or as a one-liner: char* y = strcpy(new char[x.size() + 1], x.c_str());
// use y...
delete[] y; // make sure no break, return, throw or branching bypasses this

// USING new/delete HEAP MEMORY, SMART POINTER DEALLOCATION, EXCEPTION SAFE
// see boost shared_array usage in Johannes Schaub's answer

// USING malloc/free HEAP MEMORY, MANUAL DEALLOC, NO INHERENT EXCEPTION SAFETY
char* y = strdup(x.c_str());
// use y...
free(y);

Other reasons to want a char* or const char* generated from a string

So, above you've seen how to get a (const) char*, and how to make a copy of the text independent of the original string, but what can you do with it? A random smattering of examples...

• give "C" code access to the C++ string's text, as in printf("x is '%s'", x.c_str());
• copy x's text to a buffer specified by your function's caller (e.g. strncpy(callers_buffer, callers_buffer_size, x.c_str())), or volatile memory used for device I/O (e.g. for (const char* p = x.c_str(); *p; ++p) *p_device = *p;)
• append x's text to an character array already containing some ASCIIZ text (e.g. strcat(other_buffer, x.c_str())) - be careful not to overrun the buffer (in many situations you may need to use strncat)
• return a const char* or char* from a function (perhaps for historical reasons - client's using your existing API - or for C compatibility you don't want to return a std::string, but do want to copy your string's data somewhere for the caller)
  • be careful not to return a pointer that may be dereferenced by the caller after a local string variable to which that pointer pointed has left scope
  • some projects with shared objects compiled/linked for different std::string implementations (e.g. STLport and compiler-native) may pass data as ASCIIZ to avoid conflicts

You are actually encouraged to use the inflate method of your generated Binding and not the DataBindingUtil:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    MainFragmentBinding binding = MainFragmentBinding.inflate(inflater, container, false);
    //set variables in Binding
    return binding.getRoot();
}

Docs for DataBindingUtil.inflate():

Use this version only if layoutId is unknown in advance. Otherwise, use the generated Binding's inflate method to ensure type-safe inflation.

What about using this syntax (take a look in this plunker). I just discovered this and it's pretty awesome.

ng-repeat="(key,value) in data"

Example:

<div ng-repeat="(indexX,object) in data">
    <div ng-repeat="(indexY,value) in object">
       {{indexX}} - {{indexY}} - {{value}}
    </div>
</div>

With this syntax you can give your own name to $index and differentiate the two indexes.

Every single persons suggestion to run a query in Oracle to find records whose specific field is just blank, (this is not including (null) or any other field just a blank line) did not work. I tried every single suggested code. Guess I will keep searching online.

*****UPDATE*****

I tried this and it worked, not sure why it would not work if < 1 but for some reason < 2 worked and only returned records whose field is just blank

select [columnName] from [tableName] where LENGTH(columnName) < 2 ;

I am guessing whatever script that was used to convert data over has left something in the field even though it shows blank, that is my guess anyways as to why the < 2 works but not < 1

However, if you have any other values in that column field that is less than two characters then you might have to come up with another solution. If there are not a lot of other characters then you can single them out.

Hope my solution helps someone else out there some day.

You can use the following code to get the value of the first column of the selected row of your table.

int column = 0;
int row = table.getSelectedRow();
String value = table.getModel().getValueAt(row, column).toString();

For importing database file in .sql.gz format, remove definer and import using below command

zcat path_to_db_to_import.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db_name

1. Earlier, export database in .sql.gz format using below command.

   mysqldump -u user -p old_db | gzip -9 > path_to_db_exported.sql.gz;

2. Import that exported database and removing definer using below command,

   zcat path_to_db_exported.sql.gz | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' | mysql -u user -p new_db

You can write

i = 5 + tup()[0]

Tuples can be indexed just like lists.

The main difference between tuples and lists is that tuples are immutable - you can't set the elements of a tuple to different values, or add or remove elements like you can from a list. But other than that, in most situations, they work pretty much the same.

Here's a super simple implementation that allows use of the for each construct and relies only on C++14 std library:

namespace Details {

    // simple storage of a begin and end iterator
    template<class T>
    struct iterator_range
    {
        T beginning, ending;
        iterator_range(T beginning, T ending) : beginning(beginning), ending(ending) {}

        T begin() const { return beginning; }
        T end() const { return ending; }
    };

}

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
// usage:
//  for (auto e : backwards(collection))
template<class T>
auto backwards(T & collection)
{
    using namespace std;
    return Details::iterator_range(rbegin(collection), rend(collection));
}

This works with things that supply an rbegin() and rend(), as well as with static arrays.

std::vector<int> collection{ 5, 9, 15, 22 };
for (auto e : backwards(collection))
    ;

long values[] = { 3, 6, 9, 12 };
for (auto e : backwards(values))
    ;

You must add the classpath for compile. In tomcat

classpath="C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar".

So the command is

javac -classpath "c:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar" yourfile.java .

I used Mike Hansen's solution, it is great. I modified his solution in one point, instead of replacing parts of the string I modified the XML-attribute. Maybe it is too much of an effort when you can modify the string but anyway, here is my solution for that. This could easily be further modified to change the table etc. too, which is very nice imho.

What was helpful for me was a helper sub to write the XML to a file so I could check the structure and content of it:

Sub writeStringToFile(strPath As String, strText As String)
    '#### writes a given string into a given filePath, overwriting a document if it already exists
        Dim objStream
        
        Set objStream = CreateObject("ADODB.Stream")
        objStream.Charset = "utf-8"
        objStream.Open
        objStream.WriteText strText
        objStream.SaveToFile strPath, 2
    End Sub

The XML of an/my ImportExportSpecification for a table with 2 columns looks like this:

<?xml version="1.0"?>
<ImportExportSpecification Path="mypath\mydocument.xlsx" xmlns="urn:www.microsoft.com/office/access/imexspec">
    <ImportExcel FirstRowHasNames="true" AppendToTable="myTableName" Range="myExcelWorksheetName">
        <Columns PrimaryKey="{Auto}">
            <Column Name="Col1" FieldName="SomeFieldName" Indexed="NO" SkipColumn="false" DataType="Double"/>
            <Column Name="Col2" FieldName="SomeFieldName" Indexed="NO" SkipColumn="false" DataType="Text"/>
        </Columns>
    </ImportExcel>
</ImportExportSpecification>

Then I wrote a function to modify the path. I left out error-handling here:

Function modifyDataSourcePath(strNewPath As String, strXMLSpec As String) As String
'#### Changes the path-name of an import-export specification
    Dim xDoc As MSXML2.DOMDocument60
    Dim childNodes As IXMLDOMNodeList
    Dim nodeImExSpec As MSXML2.IXMLDOMNode
    Dim childNode As MSXML2.IXMLDOMNode
    Dim attributesImExSpec As IXMLDOMNamedNodeMap
    Dim attributeImExSpec As IXMLDOMAttribute

    
    Set xDoc = New MSXML2.DOMDocument60
    xDoc.async = False: xDoc.validateOnParse = False
    xDoc.LoadXML (strXMLSpec)
    Set childNodes = xDoc.childNodes
 
    For Each childNode In childNodes
           If childNode.nodeName = "ImportExportSpecification" Then
                Set nodeImExSpec = childNode
                Exit For
            End If
    Next childNode
    
    Set attributesImExSpec = nodeImExSpec.Attributes
    
    For Each attributeImExSpec In attributesImExSpec
        If attributeImExSpec.nodeName = "Path" Then
            attributeImExSpec.Value = strNewPath
            Exit For
        End If
    Next attributeImExSpec
    
    modifyDataSourcePath = xDoc.XML
End Function

I use this in Mike's code before the newSpec is executed and instead of the replace statement. Also I write the XML-string into an XML-file in a location relative to the database but that line is optional:

Set myNewSpec = CurrentProject.ImportExportSpecifications.item("TemporaryImport")
    myNewSpec.XML = modifyDataSourcePath(myPath, myNewSpec.XML)
    Call writeStringToFile(Application.CurrentProject.Path & "\impExpSpec.xml", myNewSpec.XML)
    myNewSpec.Execute

For Windows 10 64bit:

I have tried all the suggestions here, but finally got it running as follows:

1. Uninstall all current versions of Python
2. Remove all Python references in the PATH system and user Environment variables
3. Download the latest 64bit version of Python 3.8: Python 3.8.7 currently, NOT the latest 3.9.x version which is the one I was using, and NOT 32bit.
4. Install with all options selected, including pip, and including PATH Environment variable
5. pip install tensorflow (in Admin CMD prompt)
6. Upgrade pip if prompted (optional)

How about using colors to differentiate between "apples" and "oranges" and spacing to separate "A", "B" and "C"?

Something like this:

from pylab import plot, show, savefig, xlim, figure, \
                hold, ylim, legend, boxplot, setp, axes

# function for setting the colors of the box plots pairs
def setBoxColors(bp):
    setp(bp['boxes'][0], color='blue')
    setp(bp['caps'][0], color='blue')
    setp(bp['caps'][1], color='blue')
    setp(bp['whiskers'][0], color='blue')
    setp(bp['whiskers'][1], color='blue')
    setp(bp['fliers'][0], color='blue')
    setp(bp['fliers'][1], color='blue')
    setp(bp['medians'][0], color='blue')

    setp(bp['boxes'][1], color='red')
    setp(bp['caps'][2], color='red')
    setp(bp['caps'][3], color='red')
    setp(bp['whiskers'][2], color='red')
    setp(bp['whiskers'][3], color='red')
    setp(bp['fliers'][2], color='red')
    setp(bp['fliers'][3], color='red')
    setp(bp['medians'][1], color='red')

# Some fake data to plot
A= [[1, 2, 5,],  [7, 2]]
B = [[5, 7, 2, 2, 5], [7, 2, 5]]
C = [[3,2,5,7], [6, 7, 3]]

fig = figure()
ax = axes()
hold(True)

# first boxplot pair
bp = boxplot(A, positions = [1, 2], widths = 0.6)
setBoxColors(bp)

# second boxplot pair
bp = boxplot(B, positions = [4, 5], widths = 0.6)
setBoxColors(bp)

# thrid boxplot pair
bp = boxplot(C, positions = [7, 8], widths = 0.6)
setBoxColors(bp)

# set axes limits and labels
xlim(0,9)
ylim(0,9)
ax.set_xticklabels(['A', 'B', 'C'])
ax.set_xticks([1.5, 4.5, 7.5])

# draw temporary red and blue lines and use them to create a legend
hB, = plot([1,1],'b-')
hR, = plot([1,1],'r-')
legend((hB, hR),('Apples', 'Oranges'))
hB.set_visible(False)
hR.set_visible(False)

savefig('boxcompare.png')

MySQL documentation covers this topic.

Here is a synopsis. When using join or inner join, the on condition is optional. This is different from the ANSI standard and different from almost any other database. The effect is a cross join. Similarly, you can use an on clause with cross join, which also differs from standard SQL.

A cross join creates a Cartesian product -- that is, every possible combination of 1 row from the first table and 1 row from the second. The cross join for a table with three rows ('a', 'b', and 'c') and a table with four rows (say 1, 2, 3, 4) would have 12 rows.

In practice, if you want to do a cross join, then use cross join:

from A cross join B

is much better than:

from A, B

and:

from A join B -- with no on clause

The on clause is required for a right or left outer join, so the discussion is not relevant for them.

If you need to understand the different types of joins, then you need to do some studying on relational databases. Stackoverflow is not an appropriate place for that level of discussion.

Well if you are fan of copy-paste, here it is:

#include <sstream>

template <class T>
inline std::string to_string (const T& t)
{
    std::stringstream ss;
    ss << t;
    return ss.str();
}

Or you can use an alternative:

https://github.com/kint-php/kint

It works with zero set up and has much more features than Xdebug's var_dump anyway. To bypass the nested limit on the fly with Kint, just use

 +d( $variable ); // append `+` to the dump call

It should be noted that if you use push --force with mutiple refs, they will ALL be modified as a result. Make sure to pay attention to where your git repo is configured to push to. Fortunately there is a way to safeguard the process slightly, by specifying a single branch to update. Read from the git man pages:

Note that --force applies to all the refs that are pushed, hence using it with push.default set to matching or with multiple push destinations configured with remote.*.push may overwrite refs other than the current branch (including local refs that are strictly behind their remote counterpart). To force a push to only one branch, use a + in front of the refspec to push (e.g git push origin +master to force a push to the master branch).

Edit I just finished a nice four part tutorial building an app to write, save, edit, & delete notes using jQuery mobile (only), it was very practical & useful, but it was also only for jQM. So, I looked to see what else they had on DZone.

I'm now going to start sorting through these search results. At a glance, it looks really promising. I remembered this post; so I thought I'd steer people to it. ?

You also need to define PHPIniDir - c:/php_install_path

The Problem here is that your profile was built on an expired certificated

-so you have to go inside the developer portal and renew your certificate if it was expired

-then regenerate the profile so it will be rebulit on the new certificate

i suggest to use the iPhone configuration utility tool to manage profiles on your mac

Is this what you meant to do ?

In [7]: x =  pd.DataFrame({'one' : ['one', 'two', 'This is very long string very long string very long string veryvery long string']})

In [8]: x
Out[8]: 
                                                 one
0                                                one
1                                                two
2  This is very long string very long string very...

In [9]: x['one'][2]
Out[9]: 'This is very long string very long string very long string veryvery long string'

There are 2 different places you can set it:

php.ini

post_max_size=20M
upload_max_filesize=20M

.htaccess / httpd.conf / virtualhost include

php_value post_max_size 20M
php_value upload_max_filesize 20M

Which one to use depends on what you have access to.

.htaccess will not require a server restart, but php.ini and the other apache conf files will.

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

Assuming that your objects are all of a similar type you could add a method as a category of their base class that calls the function you're using for your criteria. Then create an NSPredicate object that refers to that method.

In some category define your method that uses your function

@implementation BaseClass (SomeCategory)
- (BOOL)myMethod {
    return someComparisonFunction(self, whatever);
}
@end

Then wherever you'll be filtering:

- (NSArray *)myFilteredObjects {
    NSPredicate *pred = [NSPredicate predicateWithFormat:@"myMethod = TRUE"];
    return [myArray filteredArrayUsingPredicate:pred];
}

Of course, if your function only compares against properties reachable from within your class it may just be easier to convert the function's conditions to a predicate string.

I believe that your problem is that you're checking for an empty string using double quotes instead of single quotes. Try just changing to:

DELETE FROM table WHERE edit_user=''

If you are getting this error, it could be because you don't have a route defined for your get.

For example:

const express = require('express');

const app = express();

app.get('/people', function (req, res) {
    res.send('hello');
})

app.listen(3000);


http://http://localhost:3000/people --> this works
http://http://localhost:3000 --> this will output Cannot GET / message.

Flask-Sqlalchemy

Delete All Records

#for all records
db.session.query(Model).delete()
db.session.commit()

Deleted Single Row

here DB is the object Flask-SQLAlchemy class. It will delete all records from it and if you want to delete specific records then try filter clause in the query. ex.

#for specific value
db.session.query(Model).filter(Model.id==123).delete()
db.session.commit()

Delete Single Record by Object

record_obj = db.session.query(Model).filter(Model.id==123).first()
db.session.delete(record_obj)
db.session.commit()

https://flask-sqlalchemy.palletsprojects.com/en/2.x/queries/#deleting-records

Another way to do it is a TEXT column. And then convert the boolean value between Boolean and String before/after saving/reading the value from the database.

Ex. You have "boolValue = true;"

To String:

//convert to the string "TRUE"
string StringValue = boolValue.ToString;  

And back to boolean:

//convert the string back to boolean
bool Boolvalue = Convert.ToBoolean(StringValue);

This error message happens either because your ProfileDto class is not registered in the JAXB Content, or the class using it does not use @XmlSeeAlso(ProfileDto.class) to make processable by JAXB.

About your comment:

I was under the impression the annotations was only needed when the referenced class was a sub-class.

No, they are also needed when not declared in the JAXB context or, for example, when the only class having a static reference to it has this reference annotated with @XmlTransient. I maintain a tutorial here.

Here is what i tried to do to add parameter in the url which contain the specific character in the url.

jQuery('a[href*="google.com"]').attr('href', function(i,href) {
        //jquery date addition
        var requiredDate = new Date();
        var numberOfDaysToAdd = 60;
        requiredDate.setDate(requiredDate.getDate() + numberOfDaysToAdd); 
        //var convertedDate  = requiredDate.format('d-M-Y');
        //var newDate = datepicker.formatDate('yy/mm/dd', requiredDate );
        //console.log(requiredDate);

        var month   = requiredDate.getMonth()+1;
        var day     = requiredDate.getDate();

        var output = requiredDate.getFullYear() + '/' + ((''+month).length<2 ? '0' : '') + month + '/' + ((''+day).length<2 ? '0' : '') + day;
        //

Working Example Click

Casting is not a mathematical operation and doesn't behave as such. Try

int y = (int)round(x);

You're talking about template literals.

They allow for both multiline strings and string interpolation.

Multiline strings:

console.log(`foo_x000D_
bar`);_x000D_
// foo_x000D_
// bar

String interpolation:

var foo = 'bar';_x000D_
console.log(`Let's meet at the ${foo}`);_x000D_
// Let's meet at the bar

Using EntityManager em;

public User getUserById(Long id) {
     return em.getReference(User.class, id);
}

You can only have one return value whereas you can have multiple out parameters.

You only need to consider out parameters in those cases.

However, if you need to return more than one parameter from your method, you probably want to look at what you're returning from an OO approach and consider if you're better off return an object or a struct with these parameters. Therefore you're back to a return value again.

They are not. They're exactly the same.

However, some people say that parameters are placeholders in method signatures:

public void doMethod(String s, int i) {
  ..
}

String s and int i are sometimes said to be parameters. The arguments are the actual values/references:

myClassReference.doMethod("someString", 25);

"someString" and 25 are sometimes said to be the arguments.

--- Substituting RLC in 8051 C for speed --- Rotate left carry
Here is an example using RLC to update a serial 8 bit DAC msb first:
                               (r=DACVAL, P1.4= SDO, P1.5= SCLK)
MOV     A, r
?1:
MOV     B, #8
RLC     A
MOV     P1.4, C
CLR     P1.5
SETB    P1.5
DJNZ    B, ?1

Here is the code in 8051 C at its fastest:
sbit ACC_7  = ACC ^ 7 ; //define this at the top to access bit 7 of ACC
ACC     =   r;
B       =   8;  
do  {
P1_4    =   ACC_7;  // this assembles into mov c, acc.7  mov P1.4, c 
ACC     <<= 1;
P1_5    =   0;
P1_5    =   1;
B       --  ; 
    } while ( B!=0 );
The keil compiler will use DJNZ when a loop is written this way.
I am cheating here by using registers ACC and B in c code.
If you cannot cheat then substitute with:
P1_4    =   ( r & 128 ) ? 1 : 0 ;
r     <<=   1;
This only takes a few extra instructions.
Also, changing B for a local var char n is the same.
Keil does rotate ACC left by ADD A, ACC which is the same as multiply 2.
It only takes one extra opcode i think.
Keeping code entirely in C keeps things simpler sometimes.

31-DEC-95 isn't a string, nor is 20-JUN-94. They're numbers with some extra stuff added on the end. This should be '31-DEC-95' or '20-JUN-94' - note the single quote, '. This will enable you to do a string comparison.

However, you're not doing a string comparison; you're doing a date comparison. You should transform your string into a date. Either by using the built-in TO_DATE() function, or a date literal.

TO_DATE()

select employee_id
  from employee
 where employee_date_hired > to_date('31-DEC-95','DD-MON-YY')

This method has a few unnecessary pitfalls

• As a_horse_with_no_name noted in the comments, DEC, doesn't necessarily mean December. It depends on your NLS_DATE_LANGUAGE and NLS_DATE_FORMAT settings. To ensure that your comparison with work in any locale you can use the datetime format model MM instead
• The year '95 is inexact. You know you mean 1995, but what if it was '50, is that 1950 or 2050? It's always best to be explicit

select employee_id
  from employee
 where employee_date_hired > to_date('31-12-1995','DD-MM-YYYY')

Date literals

A date literal is part of the ANSI standard, which means you don't have to use an Oracle specific function. When using a literal you must specify your date in the format YYYY-MM-DD and you cannot include a time element.

select employee_id
  from employee
 where employee_date_hired > date '1995-12-31'

Remember that the Oracle date datatype includes a time elemement, so the date without a time portion is equivalent to 1995-12-31 00:00:00.

If you want to include a time portion then you'd have to use a timestamp literal, which takes the format YYYY-MM-DD HH24:MI:SS[.FF0-9]

select employee_id
  from employee
 where employee_date_hired > timestamp '1995-12-31 12:31:02'

Further information

NLS_DATE_LANGUAGE is derived from NLS_LANGUAGE and NLS_DATE_FORMAT is derived from NLS_TERRITORY. These are set when you initially created the database but they can be altered by changing your inialization parameters file - only if really required - or at the session level by using the ALTER SESSION syntax. For instance:

alter session set nls_date_format = 'DD.MM.YYYY HH24:MI:SS';

This means:

• DD numeric day of the month, 1 - 31
• MM numeric month of the year, 01 - 12 ( January is 01 )
• YYYY 4 digit year - in my opinion this is always better than a 2 digit year YY as there is no confusion with what century you're referring to.
• HH24 hour of the day, 0 - 23
• MI minute of the hour, 0 - 59
• SS second of the minute, 0-59

You can find out your current language and date language settings by querying V$NLS_PARAMETERSs and the full gamut of valid values by querying V$NLS_VALID_VALUES.

• Format models

Incidentally, if you want the count(*) you need to group by employee_id

select employee_id, count(*)
  from employee
 where employee_date_hired > date '1995-12-31'
 group by employee_id

This gives you the count per employee_id.

This has always worked for me:

type Props = {
  children: JSX.Element;
};

Including the fb:app_id tag in your HTML HEAD will allow the Facebook scraper to associate the Open Graph entity for that URL with an application. This will allow any admins of that app to view Insights about that URL and any social plugins connected with it.

The fb:admins tag is similar, but allows you to just specify each user ID that you would like to give the permission to do the above.

You can include either of these tags or both, depending on how many people you want to admin the Insights, etc. A single as fb:admins is pretty much a minimum requirement. The rest of the Open Graph tags will still be picked up when people share and like your URL, however it may cause problems in the future, so please include one of the above.

fb:admins is specified like this:
<meta property="fb:admins" content="USER_ID"/>
OR
<meta property="fb:admins" content="USER_ID,USER_ID2,USER_ID3"/>

and fb:app_id like this:
<meta property="fb:app_id" content="APPID"/>

A method you can use is itertuples(), it iterates over DataFrame rows as namedtuples, with index value as first element of the tuple. And it is much much faster compared with iterrows(). For itertuples(), each row contains its Index in the DataFrame, and you can use loc to set the value.

for row in df.itertuples():
    if <something>:
        df.at[row.Index, 'ifor'] = x
    else:
        df.at[row.Index, 'ifor'] = x

    df.loc[row.Index, 'ifor'] = x

Under most cases, itertuples() is faster than iat or at.

Thanks @SantiStSupery, using .at is much faster than loc.

Try with regex \d:

$words = preg_replace('/\d/', '', $words );

\d is an equivalent for [0-9] which is an equivalent for numbers range from 0 to 9.

For anyone interested, I ran into this same issue when using css modules and react css modules.

Most components have an associated css module style, and in this example my Button has its own css file, as does the Promo parent component. But I want to pass some additional styles to Button from Promo

So the styleable Button looks like this:

Button.js

import React, { Component } from 'react'
import CSSModules from 'react-css-modules'
import styles from './Button.css'

class Button extends Component {

  render() {

    let button = null,
        className = ''

    if(this.props.className !== undefined){
        className = this.props.className
    }

    button = (
      <button className={className} styleName='button'>
        {this.props.children}
      </button>
    )

    return (
        button
    );
  }
};

export default CSSModules(Button, styles, {allowMultiple: true} )

In the above Button component the Button.css styles handle the common button styles. In this example just a .button class

Then in my component where I want to use the Button, and I also want to modify things like the position of the button, I can set extra styles in Promo.css and pass through as the className prop. In this example again called .button class. I could have called it anything e.g. promoButton.

Of course with css modules this class will be .Promo__button___2MVMD whereas the button one will be something like .Button__button___3972N

Promo.js

import React, { Component } from 'react';
import CSSModules from 'react-css-modules';
import styles from './Promo.css';

import Button from './Button/Button'

class Promo extends Component {

  render() {

    return (
        <div styleName='promo' >
          <h1>Testing the button</h1>
          <Button className={styles.button} >
            <span>Hello button</span>
          </Button>
        </div>
      </Block>
    );
  }
};

export default CSSModules(Promo, styles, {allowMultiple: true} );

I realize this is an old question and has been answered but this could help someone. In your activity

private ScheduledExecutorService scheduleTaskExecutor;

In onCreate

  scheduleTaskExecutor = Executors.newScheduledThreadPool(5);

    //Schedule a task to run every 5 seconds (or however long you want)
    scheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            // Do stuff here!

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // Do stuff to update UI here!
                    Toast.makeText(MainActivity.this, "Its been 5 seconds", Toast.LENGTH_SHORT).show();
                }
            });

        }
    }, 0, 5, TimeUnit.SECONDS); // or .MINUTES, .HOURS etc.

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

You want to use timeout. timeout 10 will sleep 10 seconds

To declare a variable as a Decimal, first declare it as a Variant and then convert to Decimal with CDec. The type would be Variant/Decimal in the watch window:

Considering that programming floating point arithmetic is not what one has studied during Maths classes at school, one should always try to avoid common pitfalls by converting to decimal whenever possible.

In the example below, we see that the expression:

0.1 + 0.11 = 0.21

is either True or False, depending on whether the collectibles (0.1,0.11) are declared as Double or as Decimal:

Public Sub TestMe()

    Dim preciseA As Variant: preciseA = CDec(0.1)
    Dim preciseB As Variant: preciseB = CDec(0.11)

    Dim notPreciseA As Double: notPreciseA = 0.1
    Dim notPreciseB As Double: notPreciseB = 0.11

    Debug.Print preciseA + preciseB
    Debug.Print preciseA + preciseB = 0.21 'True

    Debug.Print notPreciseA + notPreciseB
    Debug.Print notPreciseA + notPreciseB = 0.21 'False

End Sub

I'm using such thing to clean-up the style='...' section out of tags with keeping of other attributes at the moment.

$output = preg_replace('/<([^>]+)(\sstyle=(?P<stq>["\'])(.*)\k<stq>)([^<]*)>/iUs', '<$1$5>', $input);

You can try the following:

$group = array();

foreach ( $array as $value ) {
    $group[$value['id']][] = $value;
}

var_dump($group);

Output:

array
  96 =>

      0 => 
        array
          'id' => int 96
