Here you go:

public static byte[] ConvertToByteArray(string str, Encoding encoding)
{
    return encoding.GetBytes(str);
}

public static String ToBinary(Byte[] data)
{
    return string.Join(" ", data.Select(byt => Convert.ToString(byt, 2).PadLeft(8, '0')));
}

// Use any sort of encoding you like. 
var binaryString = ToBinary(ConvertToByteArray("Welcome, World!", Encoding.ASCII));

var UTF8ToBin=function(f){for(var a,c=0,d=(f=unescape(encodeURIComponent(f))).length,b="";c<d;c++){for(a=f.charCodeAt(c).toString(2);a.length%8!=0;){a="0"+a}b+=a}return b},binToUTF8=function(f){for(var a,c=0,d=f.length,b="";c<d;c+=8){b+="%"+((a=parseInt(f.substr(c,8),2).toString(16)).length%2==0?a:"0"+a)}return decodeURIComponent(b)};

This is a small minified JavaScript Code to convert UTF8 to Binary and Vice versa.

The thing you are missing is which encoding scheme is being used. There are different ways to encode binary numbers. Look into signed number representations. For 9 bits, the ranges and the amount of numbers that can be represented will differ depending on the system used.

If you are looking for a Ruby class/method I used this, and I have also included the tests:

class Binary
  def self.binary_to_decimal(binary)
    binary_array = binary.to_s.chars.map(&:to_i)
    total = 0

    binary_array.each_with_index do |n, i|
      total += 2 ** (binary_array.length-i-1) * n
    end
    total
   end
end

class BinaryTest < Test::Unit::TestCase
  def test_1
   test1 = Binary.binary_to_decimal(0001)
   assert_equal 1, test1
  end

 def test_8
    test8 = Binary.binary_to_decimal(1000)
    assert_equal 8, test8
 end

 def test_15
    test15 = Binary.binary_to_decimal(1111)
    assert_equal 15, test15
 end

 def test_12341
    test12341 = Binary.binary_to_decimal(11000000110101)
    assert_equal 12341, test12341
 end
end

Result in string

The following function converts an integer to binary in a string (n is the number of bits):

// Convert an integer to binary (in a string)
void int2bin(unsigned integer, char* binary, int n=8)
{  
  for (int i=0;i<n;i++)   
    binary[i] = (integer & (int)1<<(n-i-1)) ? '1' : '0';
  binary[n]='\0';
}

Result in string with memory allocation

The following function converts an integer to binary in a string and allocate memory for the string (n is the number of bits):

// Convert an integer to binary (in a string)
char* int2bin(unsigned integer, int n=8)
{
  char* binary = (char*)malloc(n+1);
  for (int i=0;i<n;i++)   
    binary[i] = (integer & (int)1<<(n-i-1)) ? '1' : '0';
  binary[n]='\0';
  return binary;
}

This option allows you to write something like printf ("%s", int2bin(78)); but be careful, memory allocated for the string must be free later.

// Convert an integer to binary (in an unsigned)
unsigned int int_to_int(unsigned int k) {
    return (k == 0 || k == 1 ? k : ((k % 2) + 10 * int_to_int(k / 2)));

Please, see oficial encode() and decode() documentation from codecs library. utf-8 is the default encoding for the functions, but there are severals standard encodings in Python 3, like latin_1 or utf_32.

Yes, sure!

There...

$bin = decbin(ord($char));

... and back again.

$char = chr(bindec($bin));

I've tried this in Python 3.6.9

Convert Binary to Decimal

>>> 0b101111
47

>>> int('101111',2)
47

Convert Decimal to binary

>>> bin(47)
'0b101111'

Place a 0 as the second parameter python assumes it as decimal.

>>> int('101111',0)
101111

Without the 0b in front:

"{0:b}".format(int)

Starting with Python 3.6 you can also use formatted string literal or f-string, --- PEP:

f"{int:b}"

#include<iostream>
#include<conio.h>
#include<stdlib.h>
using namespace std;
void displayBinary(int n)
{
       char bistr[1000];
       itoa(n,bistr,2);       //2 means binary u can convert n upto base 36
       printf("%s",bistr);

}

int main()
{
    int n;
    cin>>n;
    displayBinary(n);
    getch();
    return 0;
}

According to K&R 2nd edition the results are implementation-dependent for right shifts of signed values.

Wikipedia says that C/C++ 'usually' implements an arithmetic shift on signed values.

Basically you need to either test your compiler or not rely on it. My VS2008 help for the current MS C++ compiler says that their compiler does an arithmetic shift.

I tried the above for a Float64Array and it just did not work.

I ended up realising that really the data needed to be read 'INTO' the view in correct chunks. This means reading 8 bytes at a time from the source Buffer.

Anyway this is what I ended up with...

var buff = new Buffer("40100000000000004014000000000000", "hex");
var ab = new ArrayBuffer(buff.length);
var view = new Float64Array(ab);

var viewIndex = 0;
for (var bufferIndex=0;bufferIndex<buff.length;bufferIndex=bufferIndex+8)            {

    view[viewIndex] = buff.readDoubleLE(bufferIndex);
    viewIndex++;
}

In Cygwin:

$cmp -bl <file1> <file2>

diffs binary offsets and values are in decimal and octal respectively.. Vladi.

using bitmask and bitwise and .

string int2bin(int n){
    string x;
    for(int i=0;i<32;i++){
        if(n&1) {x+='1';}
        else {x+='0';}
        n>>=1;
    }
    reverse(x.begin(),x.end());
    return x;
}

It is more that the media validates the string encoding, so we want to ensure that the data is acceptable by a handling application (and doesn't contain a binary sequence representing EOL for example)

Imagine you want to send binary data in an email with encoding UTF-8 -- The email may not display correctly if the stream of ones and zeros creates a sequence which isn't valid Unicode in UTF-8 encoding.

The same type of thing happens in URLs when we want to encode characters not valid for a URL in the URL itself:

http://www.foo.com/hello my friend -> http://www.foo.com/hello%20my%20friend

This is because we want to send a space over a system that will think the space is smelly.

All we are doing is ensuring there is a 1-to-1 mapping between a known good, acceptable and non-detrimental sequence of bits to another literal sequence of bits, and that the handling application doesn't distinguish the encoding.

In your example, man may be valid ASCII in first form; but often you may want to transmit values that are random binary (ie sending an image in an email):

MIME-Version: 1.0
Content-Description: "Base64 encode of a.gif"
Content-Type: image/gif; name="a.gif"
Content-Transfer-Encoding: Base64
Content-Disposition: attachment; filename="a.gif"

Here we see that a GIF image is encoded in base64 as a chunk of an email. The email client reads the headers and decodes it. Because of the encoding, we can be sure the GIF doesn't contain anything that may be interpreted as protocol and we avoid inserting data that SMTP or POP may find significant.

Quick and dirty version:

byte[] fileBytes = File.ReadAllBytes(inputFilename);
StringBuilder sb = new StringBuilder();

foreach(byte b in fileBytes)
{
    sb.Append(Convert.ToString(b, 2).PadLeft(8, '0'));  
}

File.WriteAllText(outputFilename, sb.ToString());

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

x = float(raw_input("enter number between 0 and 1: "))

p = 0
while ((2**p)*x) %1 != 0:
    p += 1
    # print p

    num = int (x * (2 ** p))
    # print num

    result = ''
    if num == 0:
        result = '0'
    while num > 0:
        result = str(num%2) + result
        num = num / 2

    for i in range (p - len(result)):
        result = '0' + result
    result = result[0:-p] + '.' + result[-p:]

print result #this will print result for the decimal portion

Now you want to do from binary string to Decimal but Afterword, You might be needed contrary method. It's down below.

public static String decimalToBinaryString(int value) {
    String str = "";
    while(value > 0) {
        if(value % 2 == 1) {
            str = "1"+str;
        } else {
            str = "0"+str;
        }
        value /= 2;
    }
    return str;
}

import binascii
hexa_input = input('Enter hex String to convert to Binary: ')
pad_bits=len(hexa_input)*4
Integer_output=int(hexa_input,16)
Binary_output= bin(Integer_output)[2:]. zfill(pad_bits)
print(Binary_output)
"""zfill(x) i.e. x no of 0 s to be padded left - Integers will overwrite 0 s
starting from right side but remaining 0 s will display till quantity x
[y:] where y is no of output chars which need to destroy starting from left"""

try:
    while True:
        p = ""
        a = input()
        while a != 0:
            l = a % 2
            b = a - l
            a = b / 2
            p = str(l) + p
        print(p)
except:
    print ("write 1 number")

I really struggled to find a way to read a binary file into a byte array in C++ that would output the same hex values I see in a hex editor. After much trial and error, this seems to be the fastest way to do so without extra casts. By default it loads the entire file into memory, but only prints the first 1000 bytes.

string Filename = "BinaryFile.bin";
FILE* pFile;
pFile = fopen(Filename.c_str(), "rb");
fseek(pFile, 0L, SEEK_END);
size_t size = ftell(pFile);
fseek(pFile, 0L, SEEK_SET);
uint8_t* ByteArray;
ByteArray = new uint8_t[size];
if (pFile != NULL)
{
    int counter = 0;
    do {
        ByteArray[counter] = fgetc(pFile);
        counter++;
    } while (counter <= size);
    fclose(pFile);
}
for (size_t i = 0; i < 800; i++) {
    printf("%02X ", ByteArray[i]);
}

Only integer and hex directly, I'm afraid (ECMA 334v4):

9.4.4.2 Integer literals Integer literals are used to write values of types int, uint, long, and ulong. Integer literals have two possible forms: decimal and hexadecimal.

To parse, you can use:

int i = Convert.ToInt32("01101101", 2);

printf() doesn't directly support that. Instead you have to make your own function.

Something like:

while (n) {
    if (n & 1)
        printf("1");
    else
        printf("0");

    n >>= 1;
}
printf("\n");

This should do the trick:

pw_bytes.decode("utf-8")

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

In your example, you have:

if (new BigInteger("1111000011110001", 2).toByteArray() == array)

When dealing with objects, == in java compares reference values. You're checking to see if the reference to the array returned by toByteArray() is the same as the reference held in array, which of course can never be true. In addition, array classes don't override .equals() so the behavior is that of Object.equals() which also only compares the reference values.

To compare the contents of two arrays, static array comparison methods are provided by the Arrays class

byte[] array = new BigInteger("1111000011110001", 2).toByteArray();
byte[] secondArray = new BigInteger("1111000011110001", 2).toByteArray();
if (Arrays.equals(array, secondArray))
{
    System.out.println("Yup, they're the same!");
}

Below is a re-write of a previously posted function:

def addBinary(a, b): # Example: a = '11' + b =' 100' returns as '111'.    
    for ch in a: assert ch in {'0','1'}, 'bad digit: ' + ch    
    for ch in b: assert ch in {'0','1'}, 'bad digit: ' + ch    
    sumx = int(a, 2) + int(b, 2)    
    return bin(sumx)[2:]

You can use MD5 hash function to check if two files are the same, with this you can not see the differences in a low level, but is a quick way to compare two files.

md5 <filename1>
md5 <filename2>

If both MD5 hashes (the command output) are the same, then, the two files are not different.

Looking at the two's complement system from a math point of view it really makes sense. In ten's complement, the idea is to essentially 'isolate' the difference.

Example: 63 - 24 = x

We add the complement of 24 which is really just (100 - 24). So really, all we are doing is adding 100 on both sides of the equation.

Now the equation is: 100 + 63 - 24 = x + 100, that is why we remove the 100 (or 10 or 1000 or whatever).

Due to the inconvenient situation of having to subtract one number from a long chain of zeroes, we use a 'diminished radix complement' system, in the decimal system, nine's complement.

When we are presented with a number subtracted from a big chain of nines, we just need to reverse the numbers.

Example: 99999 - 03275 = 96724

That is the reason, after nine's complement, we add 1. As you probably know from childhood math, 9 becomes 10 by 'stealing' 1. So basically it's just ten's complement that takes 1 from the difference.

In Binary, two's complement is equatable to ten's complement, while one's complement to nine's complement. The primary difference is that instead of trying to isolate the difference with powers of ten (adding 10, 100, etc. into the equation) we are trying to isolate the difference with powers of two.

It is for this reason that we invert the bits. Just like how our minuend is a chain of nines in decimal, our minuend is a chain of ones in binary.

Example: 111111 - 101001 = 010110

Because chains of ones are 1 below a nice power of two, they 'steal' 1 from the difference like nine's do in decimal.

When we are using negative binary number's, we are really just saying:

0000 - 0101 = x

1111 - 0101 = 1010

1111 + 0000 - 0101 = x + 1111

In order to 'isolate' x, we need to add 1 because 1111 is one away from 10000 and we remove the leading 1 because we just added it to the original difference.

1111 + 1 + 0000 - 0101 = x + 1111 + 1

10000 + 0000 - 0101 = x + 10000

Just remove 10000 from both sides to get x, it's basic algebra.

If you want/need to do it without int:

sum(int(c) * (2 ** i) for i, c in enumerate(s[::-1]))

This reverses the string (s[::-1]), gets each character c and its index i (for i, c in enumerate(), multiplies the integer of the character (int(c)) by two to the power of the index (2 ** i) then adds them all together (sum()).

I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse(). std::reverse() operates in place, so you may want to make a copy of the string first:

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
    std::string foo("foo");
    std::string copy(foo);
    std::cout << foo << '\n' << copy << '\n';

    std::reverse(copy.begin(), copy.end());
    std::cout << foo << '\n' << copy << '\n';
}

Integer.toBinaryString((byteValue & 0xFF) + 256).substring(1)

Below are two simple examples (in C++) among many by which you can do this.

1. We can simply count set bits (1's) using __builtin_popcount().

   int numOfOnes(int x) { return __builtin_popcount(x); }

2. Loop through all bits in an integer, check if a bit is set and if it is then increment the count variable.

   int hammingDistance(int x) { int count = 0 for(int i = 0; i < 32; i++) if(x & (1 << i)) count++; return count; }

Hope this helps!

This is my implementation.

public class Test {
    public String toBinary(String text) {
        StringBuilder sb = new StringBuilder();

        for (char character : text.toCharArray()) {
            sb.append(Integer.toBinaryString(character) + "\n");
        }

        return sb.toString();

    }
}

Except struct you can also use array module

import array
values = array.array('l') # array of long integers
values.read(fin, 1) # read 1 integer
file_size  = values[0]

Integer.parseInt(hex,16);    
System.out.print(Integer.toBinaryString(hex));

Parse hex(String) to integer with base 16 then convert it to Binary String using toBinaryString(int) method

example

int num = (Integer.parseInt("A2B", 16));
System.out.print(Integer.toBinaryString(num));

Will Print

101000101011

Max Hex vakue Handled by int is FFFFFFF

i.e. if FFFFFFF0 is passed ti will give error

Your code is very vague and not understandable, but I can provide you with an alternative.

First of all, if you want temp to go through the whole string, you can do something like this:

char *temp;
for (temp = your_string; *temp; ++temp)
    /* do something with *temp */

The term *temp as the for condition simply checks whether you have reached the end of the string or not. If you have, *temp will be '\0' (NUL) and the for ends.

Now, inside the for, you want to find the bits that compose *temp. Let's say we print the bits:

for (as above)
{
    int bit_index;
    for (bit_index = 7; bit_index >= 0; --bit_index)
    {
        int bit = *temp >> bit_index & 1;
        printf("%d", bit);
    }
    printf("\n");
}

To make it a bit more generic, that is to convert any type to bits, you can change the bit_index = 7 to bit_index = sizeof(*temp)*8-1

// Below will handle proper sizes

public static String binaryString(int i) {
    return String.format("%" + Integer.SIZE + "s", Integer.toBinaryString(i)).replace(' ', '0');
}

public static String binaryString(long i) {
    return String.format("%" + Long.SIZE + "s", Long.toBinaryString(i)).replace(' ', '0');
}

The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n on input, and conversely on output.

From the C99 standard (the N869 draft document), §7.19.2/2,

A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.

And in §7.19.3/2

Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.

About use of fseek, in §7.19.9.2/4:

For a text stream, either offset shall be zero, or offset shall be a value returned by an earlier successful call to the ftell function on a stream associated with the same file and whence shall be SEEK_SET.

About use of ftell, in §17.19.9.4:

The ftell function obtains the current value of the file position indicator for the stream pointed to by stream. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by the fseek function for returning the file position indicator for the stream to its position at the time of the ftell call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.

I think that’s the most important, but there are some more details.

public static string intToBinary(int n)
{
    String s = "";
    while (n > 0)
    {
        s =  ( (n % 2 ) == 0 ? "0" : "1") +s;
        n = n / 2;
    }
    return s;
}

int given base 2 and then hex:

>>> int('010110', 2)
22
>>> hex(int('010110', 2))
'0x16'
>>> 

>>> hex(int('0000010010001101', 2))
'0x48d'

The doc of int:

int(x[, base]) -> integer

Convert a string or number to an integer, if possible.  A floating

point argument will be truncated towards zero (this does not include a string representation of a floating point number!) When converting a string, use the optional base. It is an error to supply a base when converting a non-string. If base is zero, the proper base is guessed based on the string content. If the argument is outside the integer range a long object will be returned instead.

The doc of hex:

hex(number) -> string

Return the hexadecimal representation of an integer or long

integer.

One typical usage:

| is used to set a certain bit to 1

& is used to test or clear a certain bit

• Set a bit (where n is the bit number, and 0 is the least significant bit):

  unsigned char a |= (1 << n);

• Clear a bit:

  unsigned char b &= ~(1 << n);

• Toggle a bit:

  unsigned char c ^= (1 << n);

• Test a bit:

  unsigned char e = d & (1 << n);

Take the case of your list for example:

x | 2 is used to set bit 1 of x to 1

x & 1 is used to test if bit 0 of x is 1 or 0

You can use the string formatting mini language:

def binary(num, pre='0b', length=8, spacer=0):
    return '{0}{{:{1}>{2}}}'.format(pre, spacer, length).format(bin(num)[2:])

Demo:

print binary(1)

Output:

'0b00000001'

EDIT: based on @Martijn Pieters idea

def binary(num, length=8):
    return format(num, '#0{}b'.format(length + 2))

In addition to what others have said, note that a single character in unicode can consist of multiple bytes.

The way unicode works is that it took the old ASCII format (7-bit code that looks like 0xxx xxxx) and added multi-bytes sequences where all bytes start with 1 (1xxx xxxx) to represent characters beyond ASCII so that Unicode would be backwards-compatible with ASCII.

>>> len('Öl')  # German word for 'oil' with 2 characters

If by binary you mean bytes type, you can just use encode method of the string object that encodes your string as a bytes object using the passed encoding type. You just need to make sure you pass a proper encoding to encode function.

In [9]: "hello world".encode('ascii')                                                                                                                                                                       
Out[9]: b'hello world'

In [10]: byte_obj = "hello world".encode('ascii')                                                                                                                                                           

In [11]: byte_obj                                                                                                                                                                                           
Out[11]: b'hello world'

In [12]: byte_obj[0]                                                                                                                                                                                        
Out[12]: 104

Otherwise, if you want them in form of zeros and ones --binary representation-- as a more pythonic way you can first convert your string to byte array then use bin function within map :

>>> st = "hello world"
>>> map(bin,bytearray(st))
['0b1101000', '0b1100101', '0b1101100', '0b1101100', '0b1101111', '0b100000', '0b1110111', '0b1101111', '0b1110010', '0b1101100', '0b1100100']
 

Or you can join it:

>>> ' '.join(map(bin,bytearray(st)))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'

Note that in python3 you need to specify an encoding for bytearray function :

>>> ' '.join(map(bin,bytearray(st,'utf8')))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'

You can also use binascii module in python 2:

>>> import binascii
>>> bin(int(binascii.hexlify(st),16))
'0b110100001100101011011000110110001101111001000000111011101101111011100100110110001100100'

hexlify return the hexadecimal representation of the binary data then you can convert to int by specifying 16 as its base then convert it to binary with bin.

Why not just do this take 010010001001001 split it into two bits 8 letter each (01001000, 01001001). Then issue the powers

01001000. 01001001.

The first 8 ignore the first three they determine if it's capital or not, the go right to left doing powers of 2 (2^1, 2^2 2^3 2^4 2^5). So then add all the ones up , there's only one, and it = 8, and te eight letter in the alphabet is h so our first bit is the letter h, try it on the other bit

insert byte to specific place.

insertToArray(arr,index,item) {
   return Buffer.concat([arr.slice(0,index),Buffer.from(item,"utf-8"),arr.slice(index)]);
}

Reading binary file in Python and looping over each byte

New in Python 3.5 is the pathlib module, which has a convenience method specifically to read in a file as bytes, allowing us to iterate over the bytes. I consider this a decent (if quick and dirty) answer:

import pathlib

for byte in pathlib.Path(path).read_bytes():
    print(byte)

Interesting that this is the only answer to mention pathlib.

In Python 2, you probably would do this (as Vinay Sajip also suggests):

with open(path, 'b') as file:
    for byte in file.read():
        print(byte)

In the case that the file may be too large to iterate over in-memory, you would chunk it, idiomatically, using the iter function with the callable, sentinel signature - the Python 2 version:

with open(path, 'b') as file:
    callable = lambda: file.read(1024)
    sentinel = bytes() # or b''
    for chunk in iter(callable, sentinel): 
        for byte in chunk:
            print(byte)

(Several other answers mention this, but few offer a sensible read size.)

Best practice for large files or buffered/interactive reading

Let's create a function to do this, including idiomatic uses of the standard library for Python 3.5+:

from pathlib import Path
from functools import partial
from io import DEFAULT_BUFFER_SIZE

def file_byte_iterator(path):
    """given a path, return an iterator over the file
    that lazily loads the file
    """
    path = Path(path)
    with path.open('rb') as file:
        reader = partial(file.read1, DEFAULT_BUFFER_SIZE)
        file_iterator = iter(reader, bytes())
        for chunk in file_iterator:
            yield from chunk

Note that we use file.read1. file.read blocks until it gets all the bytes requested of it or EOF. file.read1 allows us to avoid blocking, and it can return more quickly because of this. No other answers mention this as well.

Demonstration of best practice usage:

Let's make a file with a megabyte (actually mebibyte) of pseudorandom data:

import random
import pathlib
path = 'pseudorandom_bytes'
pathobj = pathlib.Path(path)

pathobj.write_bytes(
  bytes(random.randint(0, 255) for _ in range(2**20)))

Now let's iterate over it and materialize it in memory:

>>> l = list(file_byte_iterator(path))
>>> len(l)
1048576

We can inspect any part of the data, for example, the last 100 and first 100 bytes:

>>> l[-100:]
[208, 5, 156, 186, 58, 107, 24, 12, 75, 15, 1, 252, 216, 183, 235, 6, 136, 50, 222, 218, 7, 65, 234, 129, 240, 195, 165, 215, 245, 201, 222, 95, 87, 71, 232, 235, 36, 224, 190, 185, 12, 40, 131, 54, 79, 93, 210, 6, 154, 184, 82, 222, 80, 141, 117, 110, 254, 82, 29, 166, 91, 42, 232, 72, 231, 235, 33, 180, 238, 29, 61, 250, 38, 86, 120, 38, 49, 141, 17, 190, 191, 107, 95, 223, 222, 162, 116, 153, 232, 85, 100, 97, 41, 61, 219, 233, 237, 55, 246, 181]
>>> l[:100]
[28, 172, 79, 126, 36, 99, 103, 191, 146, 225, 24, 48, 113, 187, 48, 185, 31, 142, 216, 187, 27, 146, 215, 61, 111, 218, 171, 4, 160, 250, 110, 51, 128, 106, 3, 10, 116, 123, 128, 31, 73, 152, 58, 49, 184, 223, 17, 176, 166, 195, 6, 35, 206, 206, 39, 231, 89, 249, 21, 112, 168, 4, 88, 169, 215, 132, 255, 168, 129, 127, 60, 252, 244, 160, 80, 155, 246, 147, 234, 227, 157, 137, 101, 84, 115, 103, 77, 44, 84, 134, 140, 77, 224, 176, 242, 254, 171, 115, 193, 29]

Don't iterate by lines for binary files

Don't do the following - this pulls a chunk of arbitrary size until it gets to a newline character - too slow when the chunks are too small, and possibly too large as well:

    with open(path, 'rb') as file:
        for chunk in file: # text newline iteration - not for bytes
            yield from chunk

The above is only good for what are semantically human readable text files (like plain text, code, markup, markdown etc... essentially anything ascii, utf, latin, etc... encoded) that you should open without the 'b' flag.

For a happy medium between a 2³² lookup table and iterating through each bit individually:

int bitcount(unsigned int num){
    int count = 0;
    static int nibblebits[] =
        {0, 1, 1, 2, 1, 2, 2, 3, 1, 2, 2, 3, 2, 3, 3, 4};
    for(; num != 0; num >>= 4)
        count += nibblebits[num & 0x0f];
    return count;
}

From http://ctips.pbwiki.com/CountBits

Assuming you want to parse the number of digits used to represent from a variable which is not always constant, a good way will be to use numpy.binary.

could be useful when you apply binary to power sets

import numpy as np
np.binary_repr(6, width=8)

If you want to display the bit representation of any object, not just an integer, remember to reinterpret as a char array first, then you can print the contents of that array, as hex, or even as binary (via bitset):

#include <iostream>
#include <bitset>
#include <climits>

template<typename T>
void show_binrep(const T& a)
{
    const char* beg = reinterpret_cast<const char*>(&a);
    const char* end = beg + sizeof(a);
    while(beg != end)
        std::cout << std::bitset<CHAR_BIT>(*beg++) << ' ';
    std::cout << '\n';
}
int main()
{
    char a, b;
    short c;
    a = -58;
    c = -315;
    b = a >> 3;
    show_binrep(a);
    show_binrep(b);
    show_binrep(c);
    float f = 3.14;
    show_binrep(f);
}

Note that most common systems are little-endian, so the output of show_binrep(c) is not the 1111111 011000101 you expect, because that's not how it's stored in memory. If you're looking for value representation in binary, then a simple cout << bitset<16>(c) works.

Change the Aux.js to another name, like Sig.js.

The source tree still shows it as a binary file, but you can stage(add) it and commit.

sudo apt-get install bless

Bless is GUI tool which can view, edit, seach and a lot more. Its very light weight.

== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators.

((a[0] & 1) == 0)

Similarly for all parts of the if condition.

You could encode the binary data using base64 and put it into a Base64 element; the below article is a pretty good one on the subject.

Handling Binary Data in XML Documents

I too found Python lacking when it comes to reading and writing binary files, so I wrote a small module (for Python 3.6+).

With binaryfile you'd do something like this (I'm guessing, since I don't know Fortran):

import binaryfile

def particle_file(f):
    f.array('group_ids')  # Declare group_ids to be an array (so we can use it in a loop)
    f.skip(4)  # Bytes 1-4
    num_particles = f.count('num_particles', 'group_ids', 4)  # Bytes 5-8
    f.int('num_groups', 4)  # Bytes 9-12
    f.skip(8)  # Bytes 13-20
    for i in range(num_particles):
        f.struct('group_ids', '>f')  # 4 bytes x num_particles
    f.skip(4)

with open('myfile.bin', 'rb') as fh:
    result = binaryfile.read(fh, particle_file)
print(result)

Which produces an output like this:

{
    'group_ids': [(1.0,), (0.0,), (2.0,), (0.0,), (1.0,)],
    '__skipped': [b'\x00\x00\x00\x08', b'\x00\x00\x00\x08\x00\x00\x00\x14', b'\x00\x00\x00\x14'],
    'num_particles': 5,
    'num_groups': 3
}

I used skip() to skip the additional data Fortran adds, but you may want to add a utility to handle Fortran records properly instead. If you do, a pull request would be welcome.

You can use binary literals. They are standardized in C++14. For example,

int x = 0b11000;

Support in GCC

Support in GCC began in GCC 4.3 (see https://gcc.gnu.org/gcc-4.3/changes.html) as extensions to the C language family (see https://gcc.gnu.org/onlinedocs/gcc/C-Extensions.html#C-Extensions), but since GCC 4.9 it is now recognized as either a C++14 feature or an extension (see Difference between GCC binary literals and C++14 ones?)

Support in Visual Studio

Support in Visual Studio started in Visual Studio 2015 Preview (see https://www.visualstudio.com/news/vs2015-preview-vs#C++).

If you want to do this the C++ way, do it like this:

#include <fstream>
#include <iterator>
#include <algorithm>

int main()
{
    std::ifstream input( "C:\\Final.gif", std::ios::binary );
    std::ofstream output( "C:\\myfile.gif", std::ios::binary );

    std::copy( 
        std::istreambuf_iterator<char>(input), 
        std::istreambuf_iterator<char>( ),
        std::ostreambuf_iterator<char>(output));
}

If you need that data in a buffer to modify it or something, do this:

#include <fstream>
#include <iterator>
#include <vector>

int main()
{
    std::ifstream input( "C:\\Final.gif", std::ios::binary );

    // copies all data into buffer
    std::vector<unsigned char> buffer(std::istreambuf_iterator<char>(input), {});

}

/**
 * converting decimal to binary
 *
 * @param n the number
 */
private static void toBinary(int n) {
    if (n == 0) {
        return; //end of recursion
    } else {
        toBinary(n / 2);
        System.out.print(n % 2);
    }
}

/**
 * converting decimal to binary string
 *
 * @param n the number
 * @return the binary string of n
 */
private static String toBinaryString(int n) {
    Stack<Integer> bits = new Stack<>();
    do {
        bits.push(n % 2);
        n /= 2;
    } while (n != 0);

    StringBuilder builder = new StringBuilder();
    while (!bits.isEmpty()) {
        builder.append(bits.pop());
    }
    return builder.toString();
}

Or you can use Integer.toString(int i, int radix)

e.g:(Convert 12 to binary)

Integer.toString(12, 2)

By the RFC7231 it does not matter and may be empty

How we implement json api standard based solution in the project:

post/put: outputs object attributes as in get (field filter/relations applies the same)

delete: data only contains null (for its a representation of missing object)

status for standard delete: 200

There's this way too (new to EcmaScript5):

dictionary.data.forEach(function(item){
    console.log(item.name + ' ' + item.id);
});

Same approach for images

Using the ampersand (&) will run the command in a child process (child to the current bash session). However, when you exit the session, all child processes will be killed.

using nohup + ampersand (&) will do the same thing, except that when the session ends, the parent of the child process will be changed to "1" which is the "init" process, thus preserving the child from being killed.

Unlike the C#/.NET class library (and most other sensible languages), when you pass a String in as the string-to-match argument to the string.replace method, it doesn't do a string replace. It converts the string to a RegExp and does a regex substitution. As Gumbo explains, a regex substitution requires the g?lobal flag, which is not on by default, to replace all matches in one go.

If you want a real string-based replace — for example because the match-string is dynamic and might contain characters that have a special meaning in regexen — the JavaScript idiom for that is:

var id= 'c_'+date.split('/').join('');

The sequential order of css code also matters, for example:

@media(max-width:600px){
  .example-text{
     color:red;
   }
}
.example-text{
   color:blue;
}

the above code will not working because the executed order. Need to write as following:

.example-text{
   color:blue;
}
@media(max-width:600px){
  .example-text{
     color:red;
   }
}

You need to escape the backslash \:

println yourString.replace("\\", "/")

Linus' answer to your question is "Because C++ is a horrible language"

His evidence is anecdotal at best, but he has a point..

Being more of a low level language, you would prefer it to C++..C++ is C with added libraries and compiler support for extra features (both languages have features the other language doesn't, and implement things differently), but if you have the time and experience with C, you can benefit from extra added low level related powers...[Edited](because you get used to doing more work manually rather than benefit from some powers coming from the language/compiler itself)

Why are you still using C? PDF

Ruby provides a built-in function for checking the length of a string. Say it's called s:

if s.length <= 25
  # We're OK
else
  # Too long
end

The java.util.logging.Level documentation does a good job of defining when to use a log level and the target audience of that log level.

Most of the confusion with java.util.logging is in the tracing methods. It should be in the class level documentation but instead the Level.FINE field provides a good overview:

FINE is a message level providing tracing information. All of FINE, FINER, and FINEST are intended for relatively detailed tracing. The exact meaning of the three levels will vary between subsystems, but in general, FINEST should be used for the most voluminous detailed output, FINER for somewhat less detailed output, and FINE for the lowest volume (and most important) messages. In general the FINE level should be used for information that will be broadly interesting to developers who do not have a specialized interest in the specific subsystem. FINE messages might include things like minor (recoverable) failures. Issues indicating potential performance problems are also worth logging as FINE.

One important thing to understand which is not mentioned in the level documentation is that call-site tracing information is logged at FINER.

• Logger#entering A LogRecord with message "ENTRY", log level FINER, ...
• Logger#throwing The logging is done using the FINER level...The LogRecord's message is set to "THROW"
• Logger#exiting A LogRecord with message "RETURN", log level FINER...

If you log a message as FINE you will be able to configure logging system to see the log output with or without tracing log records surrounding the log message. So use FINE only when tracing log records are not required as context to understand the log message.

FINER indicates a fairly detailed tracing message. By default logging calls for entering, returning, or throwing an exception are traced at this level.

In general, most use of FINER should be left to call of entering, exiting, and throwing. That will for the most part reserve FINER for call-site tracing when verbose logging is turned on. When swallowing an expected exception it makes sense to use FINER in some cases as the alternative to calling trace throwing method since the exception is not actually thrown. This makes it look like a trace when it isn't a throw or an actual error that would be logged at a higher level.

FINEST indicates a highly detailed tracing message.

Use FINEST when the tracing log message you are about to write requires context information about program control flow. You should also use FINEST for tracing messages that produce large amounts of output data.

CONFIG messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations. For example, CONFIG message might include the CPU type, the graphics depth, the GUI look-and-feel, etc.

The CONFIG works well for assisting system admins with the items listed above.

Typically INFO messages will be written to the console or its equivalent. So the INFO level should only be used for reasonably significant messages that will make sense to end users and system administrators.

Examples of this are tracing program startup and shutdown.

In general WARNING messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.

An example use case could be exceptions thrown from AutoCloseable.close implementations.

In general SEVERE messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.

For example, if you have transaction in your program where if any one of the steps fail then all of the steps voided then SEVERE would be appropriate to use as the log level.

You can get all the required file properties by using the code below:

FOR %%? IN (file_to_be_queried) DO (
    ECHO File Name Only       : %%~n?
    ECHO File Extension       : %%~x?
    ECHO Name in 8.3 notation : %%~sn?
    ECHO File Attributes      : %%~a?
    ECHO Located on Drive     : %%~d?
    ECHO File Size            : %%~z?
    ECHO Last-Modified Date   : %%~t?
    ECHO Parent Folder        : %%~dp?
    ECHO Fully Qualified Path : %%~f?
    ECHO FQP in 8.3 notation  : %%~sf?
    ECHO Location in the PATH : %%~dp$PATH:?
)

This is in deed due to characters messing around with the data. Using htmlentities($yourText) worked for me (I had html code inside the xml document). See http://uk3.php.net/htmlentities.

1. Open SQL Server Management Studio
2. Connect to the database engine for which you need the port number

3. Run the below query against the database

   select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null

The above query shows the local IP as well as the listening Port number

This is universal code , no matter how your input is long but in same schema if there is : separator :)

var string = "firstName:name1, lastName:last1"; 
var pass = string.replace(',',':');
var arr = pass.split(':');
var empty = {};
arr.forEach(function(el,i){
  var b = i + 1, c = b/2, e = c.toString();
     if(e.indexOf('.') != -1 ) {
     empty[el] = arr[i+1];
  } 
}); 
  console.log(empty)

Numpty here used SQL authentication

instead of Windows (correct)

when adding the login to SQL Server, which also gives you this error if you are using Windows auth.

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

If you want to check if file exists using javascript then no, as far as I know, javascript has no access to file system due to security reasons.. But as for me it is not clear enough what are you trying to do..

I use getActionCommand() to hear buttons. I apply the setActionCommand() to each button so that I can hear whenever an event is execute with event.getActionCommand("The setActionCommand() value of the button").

I use getSource() for JRadioButtons for example. I write methods that returns each JRadioButton so in my Listener Class I can specify an action each time a new JRadioButton is pressed. So for example:

public class SeleccionListener implements ActionListener, FocusListener {}

So with this I can hear button events and radioButtons events. The following are examples of how I listen each one:

public void actionPerformed(ActionEvent event) {
    if (event.getActionCommand().equals(GUISeleccion.BOTON_ACEPTAR)) {
        System.out.println("Aceptar pressed");
    }

In this case GUISeleccion.BOTON_ACEPTAR is a "public static final String" which is used in JButtonAceptar.setActionCommand(BOTON_ACEPTAR).

public void focusGained(FocusEvent focusEvent) {
    if (focusEvent.getSource().equals(guiSeleccion.getJrbDat())){
        System.out.println("Data radio button");
    }

In this one, I get the source of any JRadioButton that is focused when the user hits it. guiSeleccion.getJrbDat() returns the reference to the JRadioButton that is in the class GUISeleccion (this is a Frame)

This has already been answered, but I think the simplest syntax is:

CREATE TABLE History (
    ID int primary key IDENTITY(1,1) NOT NULL,
    . . .

The more complicated constraint index is useful when you actually want to change the options.

By the way, I prefer to name such a column HistoryId, so it matches the names of the columns in foreign key relationships.

Within your .bat file:

set mypath=%cd%

You can now use the variable %mypath% to reference the file path to the .bat file. To verify the path is correct:

@echo %mypath%

For example, a file called DIR.bat with the following contents

set mypath=%cd%
@echo %mypath%
Pause

run from the directory g:\test\bat will echo that path in the DOS command window.

With dotnetcore3.0 you can package entire solution into a single-file executable using PublishSingleFile property

-p:PublishSingleFile=True

Source Single-file executables

An example of Self Contained, Release OSX executable:

dotnet publish -c Release -r osx-x64 -p:PublishSingleFile=True --self-contained True

An example of Self Contained, Debug Linux 64bit executable:

dotnet publish -c Debug -r linux-x64 -p:PublishSingleFile=True --self-contained True

Linux build is independed of distribution and I have found them working on Ubuntu 18.10, CentOS 7.7, and Amazon Linux 2.

A Self Contained executable includes Dotnet Runtime and Runtime does not require to be installed on a target machine. The published executables are saved under:

<ProjectDir>/bin/<Release or Debug>/netcoreapp3.0/<target-os>/publish/ on Linux, OSX and

The following script done this job gracefully.

        var imageUrl = urlCreator.createObjectURL(this.response);
        var tag = document.createElement('a');
        tag.href = imageUrl;

Update: Apparently possible by passing a flag to mysql_connect(). See Executing multiple SQL queries in one statement with PHP Nevertheless, any current reader should avoid using the mysql_-class of functions and prefer PDO.

You can't do that using the regular mysql-api in PHP. Just execute two queries. The second one will be so fast that it won't matter. This is a typical example of micro optimization. Don't worry about it.

For the record, it can be done using mysqli and the mysqli_multi_query-function.

To the base question, the following will do the trick (hiding the taskbar)

private void Form1_Load(object sender, EventArgs e)
{
    this.TopMost = true;
    this.FormBorderStyle = FormBorderStyle.None;
    this.WindowState = FormWindowState.Maximized;
}

But, interestingly, if you swap those last two lines the Taskbar remains visible. I think the sequence of these actions will be hard to control with the properties window.

Seems like some kind of keyboard mapping bug. I'm Portuguese, so I'm using a PT/PT keyboard. Sublime Text 3 apparently is handling / as ~.

As has been said, they are the same. There are two because bool is a C# keyword and Boolean a .Net class.

<span class="btn-pTool">
         <a class="btn-pToolName" href="#"></a>
     </span>

Try to add display:block to .btn-pTool, and give it a width and height.

Also in your code both tbn-pTool and btn-pToolName have no text content, so that may result in them not being displayed at all.

You can try to force come content in them this way

.btn-pTool, .btn-pToolName {
    content: " ";
}

Not mention so far and an update, there is a very well establish library for handling paths that are too long. AlphaFS is a .NET library providing more complete Win32 file system functionality to the .NET platform than the standard System.IO classes. The most notable deficiency of the standard .NET System.IO is the lack of support of advanced NTFS features, most notably extended length path support (eg. file/directory paths longer than 260 characters).

If you whant only one first string, you can use simple for-loop.

var lines = File.ReadAllLines(pathToTextFile);

var firstFound = false;
for(int index = 0; index < lines.Count; index++)
{
   if(!firstFound && lines[index].Contains("CustomerEN"))
   {
      firstFound = true;
   }
   if(firstFound && lines[index].Contains("CustomerCh"))
   {
      //do, what you want, and exit the loop
      // return lines[index];
   }
}

try

    Calendar c = Calendar.getInstance();   // this takes current date
    c.set(Calendar.DAY_OF_MONTH, 1);
    System.out.println(c.getTime());       // this returns java.util.Date

Updated (Since Java 8):

import java.time.LocalDate;
LocalDate todaydate = LocalDate.now();
System.out.println("Months first date in yyyy-mm-dd: " +todaydate.withDayOfMonth(1));

// add the code to your theme function.php

This should do what you are looking for.. It assumes your list will always be just numbers. If that is not the case, just change the references to DBMS_SQL.NUMBER_TABLE to a table type that works for all of your data:

CREATE OR REPLACE PROCEDURE insert_from_lists(
    list1_in IN VARCHAR2,
    list2_in IN VARCHAR2,
    delimiter_in IN VARCHAR2 := ','
)
IS 
    v_tbl1 DBMS_SQL.NUMBER_TABLE;
    v_tbl2 DBMS_SQL.NUMBER_TABLE;

    FUNCTION list_to_tbl
    (
        list_in IN VARCHAR2
    )
    RETURN DBMS_SQL.NUMBER_TABLE
    IS
        v_retval DBMS_SQL.NUMBER_TABLE;
    BEGIN

        IF list_in is not null
        THEN
            /*
            || Use lengths loop through the list the correct amount of times,
            || and substr to get only the correct item for that row
            */
            FOR i in 1 .. length(list_in)-length(replace(list_in,delimiter_in,''))+1
            LOOP
                /*
                || Set the row = next item in the list
                */
                v_retval(i) := 
                        substr (
                            delimiter_in||list_in||delimiter_in,
                            instr(delimiter_in||list_in||delimiter_in, delimiter_in, 1, i  ) + 1,
                            instr (delimiter_in||list_in||delimiter_in, delimiter_in, 1, i+1) - instr (delimiter_in||list_in||delimiter_in, delimiter_in, 1, i) -1
                        );
            END LOOP;
        END IF;

        RETURN v_retval;

    END list_to_tbl;
BEGIN 
   -- Put lists into collections
   v_tbl1 := list_to_tbl(list1_in);
   v_tbl2 := list_to_tbl(list2_in);

   IF v_tbl1.COUNT <> v_tbl2.COUNT
   THEN
      raise_application_error(num => -20001, msg => 'Length of lists do not match');
   END IF;

   -- Bulk insert from collections
   FORALL i IN INDICES OF v_tbl1
      insert into tmp (a, b)
      values (v_tbl1(i), v_tbl2(i));

END insert_from_lists; 

Here's an improvement to Gavin's answer. marcp's solution is similar also, but neither postpone the division.

This actually turns out to be a practical application of Gareth Rees' answer as well, because the cross-product's equivalent in 2D is the perp-dot-product, which is what this code uses three of. Switching to 3D and using the cross-product, interpolating both s and t at the end, results in the two closest points between the lines in 3D. Anyway, the 2D solution:

int get_line_intersection(float p0_x, float p0_y, float p1_x, float p1_y, 
    float p2_x, float p2_y, float p3_x, float p3_y, float *i_x, float *i_y)
{
    float s02_x, s02_y, s10_x, s10_y, s32_x, s32_y, s_numer, t_numer, denom, t;
    s10_x = p1_x - p0_x;
    s10_y = p1_y - p0_y;
    s32_x = p3_x - p2_x;
    s32_y = p3_y - p2_y;

    denom = s10_x * s32_y - s32_x * s10_y;
    if (denom == 0)
        return 0; // Collinear
    bool denomPositive = denom > 0;

    s02_x = p0_x - p2_x;
    s02_y = p0_y - p2_y;
    s_numer = s10_x * s02_y - s10_y * s02_x;
    if ((s_numer < 0) == denomPositive)
        return 0; // No collision

    t_numer = s32_x * s02_y - s32_y * s02_x;
    if ((t_numer < 0) == denomPositive)
        return 0; // No collision

    if (((s_numer > denom) == denomPositive) || ((t_numer > denom) == denomPositive))
        return 0; // No collision
    // Collision detected
    t = t_numer / denom;
    if (i_x != NULL)
        *i_x = p0_x + (t * s10_x);
    if (i_y != NULL)
        *i_y = p0_y + (t * s10_y);

    return 1;
}

Basically it postpones the division until the last moment, and moves most of the tests until before certain calculations are done, thereby adding early-outs. Finally, it also avoids the division by zero case which occurs when the lines are parallel.

You also might want to consider using an epsilon test rather than comparison against zero. Lines that are extremely close to parallel can produce results that are slightly off. This is not a bug, it is a limitation with floating point math.

Cache

Clear your cache. http://support.google.com/chrome/bin/answer.py?hl=en&answer=95582 And test another browser.

Some where able to get an updated favicon by adding an URL parameter: ?v=1 after the link href which changes the resource link and therefore loads the favicon without cache (thanks @Stanislav).

<link rel="icon" type="image/x-icon" href="favicon.ico?v=2"  />

Favicon Usage

How did you import the favicon? How you should add it.

Normal favicon:

<link rel="icon" href="favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />

PNG/GIF favicon:

<link rel="icon" type="image/gif" href="favicon.gif" />
<link rel="icon" type="image/png" href="favicon.png" />

in the <head> Tag.

Chrome local problem

Another thing could be the problem that chrome can't display favicons, if it's local (not uploaded to a webserver). Only if the file/icon would be in the downloads directory chrome is allowed to load this data - more information about this can be found here: local (file://) website favicon works in Firefox, not in Chrome or Safari- why?

Renaming

Try to rename it from favicon.{whatever} to {yourfaviconname}.{whatever} but I would suggest you to still have the normal favicon. This has solved my issue on IE.

Base64 approach

Found another solution for this which works great! I simply added my favicon as Base64 Encoded Image directly inside the tag like this:

Generate favicons

I can really suggest you this page: http://www.favicon-generator.org/ to create all types of favicons you need.

In First activity:

ArrayList<ContactBean> fileList = new ArrayList<ContactBean>();
Intent intent = new Intent(MainActivity.this, secondActivity.class);
intent.putExtra("FILES_TO_SEND", fileList);
startActivity(intent);

In receiver activity:

ArrayList<ContactBean> filelist =  (ArrayList<ContactBean>)getIntent().getSerializableExtra("FILES_TO_SEND");`

If you need to focus some textbox and your only problem is that the entire text gets highlighted whereas you want the caret to be at the end, then in that specific case, you can use this trick of setting the textbox value to itself after focus:

$("#myinputfield").focus().val($("#myinputfield").val());

Just put your sound file in the Res\raw\siren.mp3 folder, then use this code:

For Custom Sound:

Notification notification = builder.build();
notification.sound = Uri.parse("android.resource://"
            + context.getPackageName() + "/" + R.raw.siren);

For Default Sound:

notification.defaults |= Notification.DEFAULT_SOUND;

For Custom Vibrate:

long[] vibrate = { 0, 100, 200, 300 };
notification.vibrate = vibrate;

For Default Vibrate:

notification.defaults |= Notification.DEFAULT_VIBRATE;

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

Duplicate name Classes

like

class BackGroundTask extends AsyncTask<String, Void, Void> {

and

class BackgroundTask extends AsyncTask<String, Void, Void> {

I was having the problem as a beginner..........

There was issue in the path of the xml file I have saved.

If you only need to replace characters in one specific column, somehow regex=True and in place=True all failed, I think this way will work:

data["column_name"] = data["column_name"].apply(lambda x: x.replace("characters_need_to_replace", "new_characters"))

lambda is more like a function that works like a for loop in this scenario. x here represents every one of the entries in the current column.

The only thing you need to do is to change the "column_name", "characters_need_to_replace" and "new_characters".

@everestial007 's solution worked for me. This is how I improved it for my use case, which is to have the columns of each different df with a different suffix so I can more easily differentiate between the dfs in the final merged dataframe.

from functools import reduce
import pandas as pd
dfs = [df1, df2, df3, df4]
suffixes = [f"_{i}" for i in range(len(dfs))]
# add suffixes to each df
dfs = [dfs[i].add_suffix(suffixes[i]) for i in range(len(dfs))]
# remove suffix from the merging column
dfs = [dfs[i].rename(columns={f"date{suffixes[i]}":"date"}) for i in range(len(dfs))]
# merge
dfs = reduce(lambda left,right: pd.merge(left,right,how='outer', on='date'), dfs)

Hello I solved it like this:

Converting VARCHAR2 to CLOB

In PL/SQL a CLOB can be converted to a VARCHAR2 with a simple assignment, SUBSTR, and other methods. A simple assignment will only work if the CLOB is less then or equal to the size of the VARCHAR2. The limit is 32767 in PL/SQL and 4000 in SQL (although 12c allows 32767 in SQL).

For example, this code converts a small CLOB through a simple assignment and then coverts the beginning of a larger CLOB.

declare
    v_small_clob clob := lpad('0', 1000, '0');
    v_large_clob clob := lpad('0', 32767, '0') || lpad('0', 32767, '0');
    v_varchar2   varchar2(32767);
begin
    v_varchar2 := v_small_clob;
    v_varchar2 := substr(v_large_clob, 1, 32767);
end;

LONG?

The above code does not convert the value to a LONG. It merely looks that way because of limitations with PL/SQL debuggers and strings over 999 characters long.

For example, in PL/SQL Developer, open a Test window and add and debug the above code. Right-click on v_varchar2 and select "Add variable to Watches". Step through the code and the value will be set to "(Long Value)". There is a ... next to the text but it does not display the contents.

C#?

I suspect the real problem here is with C# but I don't know how enough about C# to debug the problem.

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

If you are rounding it there is no good way to get it exactly the same in all case.

You can take the decimal part of the N percentages you have (in the example you gave it is 4).

Add the decimal parts. In your example you have total of fractional part = 3.

Ceil the 3 numbers with highest fractions and floor the rest.

(Sorry for the edits)

Python 3 has this:

from typing import List

def isit(value):
    return isinstance(value, List)

isit([1, 2, 3])  # True
isit("test")  # False
isit({"Hello": "Mars"})  # False
isit((1, 2))  # False

So to check for both Lists and Tuples, it would be:

from typing import List, Tuple

def isit(value):
    return isinstance(value, List) or isinstance(value, Tuple)

FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse)context.getExternalContext().getResponse();
response.sendRedirect("somePage.jsp");

In the league of stupid Monday morning mistakes, using round brackets instead of square brackets when trying to access an item in the list will also give you the same error message:

l=[1,2,3]

print(l[2])#GOOD
print(l(2))#BAD

TypeError: 'list' object is not callable

If you can use javascript and strictly require it on your web, you can put textboxes, checkboxes and whatever on each row of your table and at the end of each row place button (or link of class rowSubmit) "save". Without any FORM tag. Form than will be simulated by JS and Ajax like this:

<script type="text/javascript">
$(document).ready(function(){
  $(".rowSubmit").click(function()
  {
     var form = '<form><table><tr>' + $(this).closest('tr').html() + '</tr></table></form>';
     var serialized = $(form).serialize(); 
     $.get('url2action', serialized, function(data){
       // ... can be empty
     }); 
   });
});        
</script>

What do you think?

PS: If you write in jQuery this:

$("valid HTML string")
$(variableWithValidHtmlString)

It will be turned into jQuery object and you can work with it as you are used to in jQuery.

For an array of strings (but not an array of objects), you can check if an item exists by calling .indexOf() and if it doesn't then just push the item into the array:

var newItem = "NEW_ITEM_TO_ARRAY";_x000D_
var array = ["OLD_ITEM_1", "OLD_ITEM_2"];_x000D_
_x000D_
array.indexOf(newItem) === -1 ? array.push(newItem) : console.log("This item already exists");_x000D_
_x000D_
console.log(array)

The simplest approach is to encapsulate the two values together into a type which has both the image and the file. Then build an ArrayList of that and shuffle it.

That improves encapsulation as well, giving you the property that you'll always have the same number of files as images automatically.

An alternative if you really don't like that idea would be to write the shuffle code yourself (there are plenty of examples of a modified Fisher-Yates shuffle in Java, including several on Stack Overflow I suspect) and just operate on both lists at the same time. But I'd strongly recommend going with the "improve encapsulation" approach.

The actual problem is not IE8, but the hacks that you use for earlier versions of IE.

IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.

I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...

If you updated manifest through the filesystem or Git it won't pick up the changes.

var start = new Date("2014-05-01"); //yyyy-mm-dd
var end = new Date("2014-05-05"); //yyyy-mm-dd

while(start <= end){

    var mm = ((start.getMonth()+1)>=10)?(start.getMonth()+1):'0'+(start.getMonth()+1);
    var dd = ((start.getDate())>=10)? (start.getDate()) : '0' + (start.getDate());
    var yyyy = start.getFullYear();
    var date = dd+"/"+mm+"/"+yyyy; //yyyy-mm-dd

    alert(date); 

    start = new Date(start.setDate(start.getDate() + 1)); //date increase by 1
}

I've read all the comments. It's interesting to notice what happens when you print out this:

printf("\nInteger =    %d\n", EOF);             //OUTPUT = -1
printf("Decimal =    %d\n", EOF);               //OUTPUT = -1
printf("Octal =  %o\n", EOF);                   //OUTPUT = 37777777777
printf("Hexadecimal =  %x\n", EOF);             //OUTPUT = ffffffff
printf("Double and float =  %f\n", EOF);        //OUTPUT = 0.000000
printf("Long double =  %Lf\n", EOF);            //OUTPUT = 0.000000
printf("Character =  %c\n", EOF);               //OUTPUT = nothing

As we can see here, EOF is NOT a character (whatsoever).

There is no build-in variable for this purpose, but you can always find out the playbook's absolute path with "pwd" command, and register its output to a variable.

- name: Find out playbook's path
  shell: pwd
  register: playbook_path_output
- debug: var=playbook_path_output.stdout

Now the path is available in variable playbook_path_output.stdout

In general, that's not how systems use GET requests. So, it will be hard to get your libraries to play along. In fact, the spec says that "If the request method is a case-sensitive match for GET or HEAD act as if data is null." So, I think you are out of luck unless the browser you are using doesn't respect that part of the spec.

You can probably setup an endpoint on your own server for a POST ajax request, then redirect that in your server code to a GET request with a body.

If you aren't absolutely tied to GET requests with the body being the data, you have two options.

POST with data: This is probably what you want. If you are passing data along, that probably means you are modifying some model or performing some action on the server. These types of actions are typically done with POST requests.

GET with query string data: You can convert your data to query string parameters and pass them along to the server that way.

Looks like when upgrading to OS X El Capitain, the /usr/local directory is modified in multiple ways :

1. user permissions are reset (this is also a problem for people using Homebrew)
2. binaries and symlinks might have been deleted or altered

[Edit] There's also a preliminary thing to do : upgrade Xcode...

Solution for #1 :

$ sudo chown -R $(whoami):admin /usr/local

This will fix permissions on the /usr/local directory which will then help both gem install and brew install|link|... commands working properly.

Solution to #2 :

Ruby based issues

Make sure you have fixed the permissions of the /usr/local directory (see #1 above)

First try to reinstall your gem using :

sudo gem install <gemname>

Note that it will install the latest version of the specified gem.

If you don't want to face backward-compatibility issues, I suggest that you first determine which version of which gem you want to get and then reinstall it with the -v version. See an exemple below to make sure that the system won't get a new version of capistrano.

$ gem list | grep capistrano
capistrano (3.4.0, 3.2.1, 2.14.2)
$ sudo gem install capistrano -v 3.4.0

Brew based issues

Update brew and upgrade your formulas

$ brew update
$ brew upgrade

You might also need to re-link some of them manually

$ brew link <formula>

In case nothing of the previous answers worked, add one of these paths to your PATH environment variable:

C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64
C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x86

Of course, make sure they exist first and that they contain the DLL files needed. If they don't exist, try installing "Windows Universal CRT SDK" from the Visual Studio 2015 or Visual Studio 2017 installer.

This is worked for me :)

I was trying to test an extjs application and after sucessfully setting a testingAuthenticationToken this suddenly stopped working with no obvious cause.

I couldn't get the above answers to work so my solution was to skip out this bit of spring in the test environment. I introduced a seam around spring like this:

public class SpringUserAccessor implements UserAccessor
{
    @Override
    public User getUser()
    {
        SecurityContext context = SecurityContextHolder.getContext();
        Authentication authentication = context.getAuthentication();
        return (User) authentication.getPrincipal();
    }
}

User is a custom type here.

I'm then wrapping it in a class which just has an option for the test code to switch spring out.

public class CurrentUserAccessor
{
    private static UserAccessor _accessor;

    public CurrentUserAccessor()
    {
        _accessor = new SpringUserAccessor();
    }

    public User getUser()
    {
        return _accessor.getUser();
    }

    public static void UseTestingAccessor(User user)
    {
        _accessor = new TestUserAccessor(user);
    }
}

The test version just looks like this:

public class TestUserAccessor implements UserAccessor
{
    private static User _user;

    public TestUserAccessor(User user)
    {
        _user = user;
    }

    @Override
    public User getUser()
    {
        return _user;
    }
}

In the calling code I'm still using a proper user loaded from the database:

    User user = (User) _userService.loadUserByUsername(username);
    CurrentUserAccessor.UseTestingAccessor(user);

Obviously this wont be suitable if you actually need to use the security but I'm running with a no-security setup for the testing deployment. I thought someone else might run into a similar situation. This is a pattern I've used for mocking out static dependencies before. The other alternative is you can maintain the staticness of the wrapper class but I prefer this one as the dependencies of the code are more explicit since you have to pass CurrentUserAccessor into classes where it is required.

1. Go to services.msc from run prompt.
2. Restart the services of SQL server(MSSQLSERVER)
3. Restart the services of SQL server(SQLEXPRESS)

I checked your XAML, it works fine - e.g. both labels have a gray foreground.
My guess is that you have some style which is affecting the way it looks...

Try moving your XAML to a brand-new window and see for yourself... Then, check if you have any themes or styles (in the Window.Resources for instance) which might be affecting the labels...

This works for me and you don't need the inline script:

Javascript:

    $(document).ready(function() {
    $('.showme').bind('click', function() {

        var id=$(this).attr("id");
        var num=$(this).attr("class");
        var poststr="request="+num+"&moreinfo="+id;
        $.ajax({
              url:"testme.php",
              cache:0,
              data:poststr,
              success:function(result){
                     document.getElementById("stuff").innerHTML=result;
               }
        }); 
    });
 });

HTML:

    <div class='request_1 showme' id='rating_1'>More stuff 1</div>
    <div class='request_2 showme' id='rating_2'>More stuff 2</div>
    <div class='request_3 showme' id='rating_3'>More stuff 3</div>

    <div id="stuff">Here is some stuff that will update when the links above are clicked</div>

The request is sent to testme.php:

    header("Cache-Control: no-cache");
    header("Pragma: nocache");

    $request_id = preg_replace("/[^0-9]/","",$_REQUEST['request']);
    $request_moreinfo = preg_replace("/[^0-9]/","",$_REQUEST['moreinfo']);

    if($request_id=="1")
    {
        echo "show 1";
    }
    elseif($request_id=="2")
    {
        echo "show 2";
    }
    else
    {
        echo "show 3";
    }

Try

$myLastElement = end($yourArray);

To reset it (thanks @hopeseekr):

 reset($yourArray);

Link to manual

@David Murdoch added: $myLastElement = end(array_values($yourArray));// and now you don't need to call reset(). On E_STRICT this produces the warning

Strict Standards: Only variables should be passed by reference

Thanks o_O Tync and everyone!

I need exactly this requirement during my Travis job but with multiple values. I start with this solution but when calling multiple time this is very slow (I need 5 expresions).

I wrote a simple maven plugin to extract pom.xml's values into .sh file.

https://github.com/famaridon/ci-tools-maven-plugin

mvn com.famaridon:ci-tools-maven-plugin:0.0.1-SNAPSHOT:environment -Dexpressions=project.artifactId,project.version,project.groupId,project.build.sourceEncoding

Will produce that:

#!/usr/bin/env bash
CI_TOOLS_PROJECT_ARTIFACTID='ci-tools-maven-plugin';
CI_TOOLS_PROJECT_VERSION='0.0.1-SNAPSHOT';
CI_TOOLS_PROJECT_GROUPID='com.famaridon';
CI_TOOLS_PROJECT_BUILD_SOURCEENCODING='UTF-8';

now you can simply source the file

source .target/ci-tools-env.sh

Have fun.

Here is the complete solution if you want to control the corner radius of the dialog and preserve elevation shadow

Dialog:

class OptionsDialog: DialogFragment() {

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup, savedInstanceState: Bundle?): View {
    dialog?.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
    return inflater.inflate(R.layout.dialog_options, container)
}

}

dialog_options.xml layout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

<androidx.cardview.widget.CardView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="40dp"
    app:cardElevation="20dp"
    app:cardCornerRadius="12dp">

    <androidx.constraintlayout.widget.ConstraintLayout
        id="@+id/actual_content_goes_here"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.cardview.widget.CardView>
</FrameLayout>

The key is to wrap the CardView with another ViewGroup (here FrameLayout) and set margins to create space for the elevation shadow.

I had similar question however mine involved a column Convert(date,mydatetime). I had to alter the best answer as follows:

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

If you want to apply it as a commit, use git am.

I'm sure someone can do better, but this works:

sapply(as.character(q.data$string), function(x, letter = "a"){
  sum(unlist(strsplit(x, split = "")) == letter)
})
greatgreat      magic        not 
     2          1          0 

or in a function:

countLetter <- function(charvec, letter){
  sapply(charvec, function(x, letter){
    sum(unlist(strsplit(x, split = "")) == letter)
  }, letter = letter)
}
countLetter(as.character(q.data$string),"a")

In javascript you can do:

window.open(url, "_blank");

Just to add

KILL QUERY **Id** where Id is connection id from show processlist

is more preferable if you are do not want to kill the connection usually when running from some application.

For more details you can read mysql doc here

A DataSet already contains DataTables. You can just use:

DataTable firstTable = dataSet.Tables[0];

or by name:

DataTable customerTable = dataSet.Tables["Customer"];

Note that you should have using statements for your SQL code, to ensure the connection is disposed properly:

using (SqlConnection conn = ...)
{
    // Code here...
}

public String[] getDirectoryList(String path) {
    String[] dirListing = null;
    File dir = new File(path);
    dirListing = dir.list();

    Arrays.sort(dirListing, 0, dirListing.length);
    return dirListing;
}

HTML Code:

 <form method="post" action="#" id="#">
<div class="form-group files color">
    <input type="file" class="form-control" multiple="">
</div>

CSS:

.files input {
outline: 2px dashed #92b0b3;

Since java 7 you can the java.nio package to achieve the same result:

Path dir = ...;
List<File> files = new ArrayList<>();
try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir, "*.{java,class,jar}")) {
    for (Path entry: stream) {
        files.add(entry.toFile());
    }
    return files;
} catch (IOException x) {
    throw new RuntimeException(String.format("error reading folder %s: %s",
    dir,
    x.getMessage()),
    x);
}

Here are the three ways for <a> tag's href tag property refer to nothing:

<a href="JavaScript:void(0)"> link </a>

<a href="javascript:;">link</a >

<a href="#" onclick="return false;"> Link </a>

This is for UK landlines without the Country Code

function format_phone_number($number) {
    $result = preg_replace('~.*(\d{2})[^\d]{0,7}(\d{4})[^\d]{0,7}(\d{4}).*~', '$1 $2 $3', $number);
    return $result;
}

Result:

2012345678
becomes
20 1234 5678

I followed approach as shown in code below to return a dictionary. Created a class and declared dictionary as global and created a function to add value corresponding to some keys in dictionary.

**Note have used Python 2.7 so some minor modification might be required for Python 3+

class a:
    global d
    d={}
    def get_config(self,x):
        if x=='GENESYS':
            d['host'] = 'host name'
            d['port'] = '15222'
        return d

Calling get_config method using class instance in a separate python file:

from constant import a
class b:
    a().get_config('GENESYS')
    print a().get_config('GENESYS').get('host')
    print a().get_config('GENESYS').get('port')

I don't think so. The API's will provide access to delayed quotes, there is no way that real time data or tick data, will be provided for free.

Use strtotime() on your first date then date('Y-m-d') to convert it back:

$time = strtotime('10/16/2003');

$newformat = date('Y-m-d',$time);

echo $newformat;
// 2003-10-16

Make note that there is a difference between using forward slash / and hyphen - in the strtotime() function. To quote from php.net:

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

To avoid potential ambiguity, it's best to use ISO 8601 (YYYY-MM-DD) dates or DateTime::createFromFormat() when possible.

echo "blahblah"> txt.txt will erase the txt and put blahblah in it's place

echo "blahblah">> txt.txt will write blahblah on a new line in the txt

I think that both will create a new txt if none exists (I know that the first one does)

Where "txt.txt" is written above, a file path can be inserted if wanted. e.g. C:\Users\<username>\desktop, which will put it on their desktop.

You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.

I have code on GitHub which uses System.Windows.Forms NotifyIcon Component from within a WPF application, the code can be viewed at https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs

Here are the summary bits:

Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State.

At class-level:

private System.Windows.Forms.NotifyIcon notifyIcon = null;

During OnInitialize():

notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];

During OnLoaded():

notifyIcon.Visible = true;

And for interaction (shown as notifyIcon.Click and DoubleClick above):

void notifyIcon_Click(object sender, EventArgs e)
{
    ShowQuickLaunchMenu();
}

From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.

It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.

Hope that helps.

It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.

The window.navigator.platform property is not spoofed when the userAgent string is changed. I tested on my Mac if I change the userAgent to iPhone or Chrome Windows, navigator.platform remains MacIntel.

The property is also read-only

I could came up with the following table

Mac Computers

Mac68K Macintosh 68K system.
MacPPC Macintosh PowerPC system.
MacIntel Macintosh Intel system.

iOS Devices

iPhone iPhone.
iPod iPod Touch.
iPad iPad.

Modern macs returns navigator.platform == "MacIntel" but to give some "future proof" don't use exact matching, hopefully they will change to something like MacARM or MacQuantum in future.

var isMac = navigator.platform.toUpperCase().indexOf('MAC')>=0;

To include iOS that also use the "left side"

var isMacLike = /(Mac|iPhone|iPod|iPad)/i.test(navigator.platform);
var isIOS = /(iPhone|iPod|iPad)/i.test(navigator.platform);

var is_OSX = /(Mac|iPhone|iPod|iPad)/i.test(navigator.platform);_x000D_

out.innerHTML += "\nPlatform: " + navigator.platform;

Since most O.S. use the close button on the right, you can just move the close button to the left when the user is on a MacLike O.S., otherwise isn't a problem if you put it on the most common side, the right.

Alternatively, if you have Node.js installed, you can use the following command:

npx degit GIT_REPO

npx comes with Node, and it allows you to run binary node-based packages without installing them first (alternatively, you can first install degit globally using npm i -g degit).

Degit is a tool created by Rich Harris, the creator of Svelte and Rollup, which he uses to quickly create a new project by cloning a repository without keeping the git folder. But it can also be used to clone any repo once...

In Zend Framework 2.0 i had this problem. Can be solved in two way .htaccess or php header i prefer .htaccess so i modified .htaccess from:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

to

RewriteEngine On

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

and it start to work

The pattern \d might not be supported by your sed. Try [0-9] or [[:digit:]] instead.

To only print the actual match (not the entire matching line), use a substitution.

sed -n 's/.*\([0-9][0-9]*G[0-9][0-9]*\).*/\1/p'

Another short oneliner:

mydict = {'c': 1, 'b': 2, 'a': 3}
print(*sorted(mydict.items()), sep='\n')

Had the same issue, my app is behind nginx. Making these changes to my Nginx config removed the error.

location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
}

Something like this would let you take over the click of each internal link and scroll to the position of the corresponding bookmark:

$(function(){
  $('a[href^=#]').click(function(e){
    var name = $(this).attr('href').substr(1);
    var pos = $('a[name='+name+']').offset();
    $('body').animate({ scrollTop: pos.top });
    e.preventDefault();
  });
});

var str = "This is a single quote: ' and so is this: '";
console.log(str);

var replaced = str.replace(/'/g, "\\'");
console.log(replaced);

Gives you:

This is a single quote: ' and so is this: '
This is a single quote: \' and so is this: \'

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

Ubuntu 14.04 LTS, in Amazon EC2. The following steps resolved this issue for me:

1. Edit server.xml and change port="8080" to "80"

sudo vi /var/lib/tomcat7/conf/server.xml

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

2. Edit tomcat7 file (if the file is not created then you need to create it)

sudo vi /etc/default/tomcat7

uncomment and change #AUTHBIND=no to yes

3. Install authbind

sudo apt-get install authbind

4. Run the following commands to provide tomcat7 read+execute on port 80.

sudo touch /etc/authbind/byport/80
sudo chmod 500 /etc/authbind/byport/80
sudo chown tomcat7 /etc/authbind/byport/80

5. Restart tomcat:

sudo /etc/init.d/tomcat7 restart

You can do

[5, 10].min

or

[4, 7].max

They come from the Enumerable module, so anything that includes Enumerable will have those methods available.

v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.

@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].

[4, 5, 7, 10].minmax
=> [4, 10]

If you're using Eclipse, just have your WSDL in a .wsdl file, eclipse will validate it automatically.

From the Doc

The WSDL validator handles validation according to the 4 step process defined above. Steps 1 and 2 are both delegated to Apache Xerces (and XML parser). Step 3 is handled by the WSDL validator and any extension namespace validators (more on extensions below). Step 4 is handled by any declared custom validators (more on this below as well). Each step must pass in order for the next step to run.

What you need to do is this:

int[] list1 = new int[4] { 1, 2, 3, 4};
int[] list2 = new int[4] { 5, 6, 7, 8};
int[] list3 = new int[4] { 1, 3, 2, 1 };
int[] list4 = new int[4] { 5, 4, 3, 2 };

int[][] lists = new int[][] {  list1 ,  list2 ,  list3 ,  list4  };

Another alternative would be to create a List<int[]> type:

List<int[]> data=new List<int[]>(){list1,list2,list3,list4};

Perl one-liner:

perl -e 'local $/; print unpack "H*", <>' file

To simply repeat the same letter 10 times:

string_val = "x" * 10  # gives you "xxxxxxxxxx"

And if you want something more complex, like n random lowercase letters, it's still only one line of code (not counting the import statements and defining n):

from random import choice
from string import ascii_lowercase
n = 10

string_val = "".join(choice(ascii_lowercase) for i in range(n))

1) Almost-English style:

Test for presence using the in operator, then apply the remove method.

if thing in some_list: some_list.remove(thing)

The removemethod will remove only the first occurrence of thing, in order to remove all occurrences you can use while instead of if.

while thing in some_list: some_list.remove(thing)    

• Simple enough, probably my choice.for small lists (can't resist one-liners)

2) Duck-typed, EAFP style:

This shoot-first-ask-questions-last attitude is common in Python. Instead of testing in advance if the object is suitable, just carry out the operation and catch relevant Exceptions:

try:
    some_list.remove(thing)
except ValueError:
    pass # or scream: thing not in some_list!
except AttributeError:
    call_security("some_list not quacking like a list!")

Off course the second except clause in the example above is not only of questionable humor but totally unnecessary (the point was to illustrate duck-typing for people not familiar with the concept).

If you expect multiple occurrences of thing:

while True:
    try:
        some_list.remove(thing)
    except ValueError:
        break

• a little verbose for this specific use case, but very idiomatic in Python.
• this performs better than #1
• PEP 463 proposed a shorter syntax for try/except simple usage that would be handy here, but it was not approved.

However, with contextlib's suppress() contextmanager (introduced in python 3.4) the above code can be simplified to this:

with suppress(ValueError, AttributeError):
    some_list.remove(thing)

Again, if you expect multiple occurrences of thing:

with suppress(ValueError):
    while True:
        some_list.remove(thing)

3) Functional style:

Around 1993, Python got lambda, reduce(), filter() and map(), courtesy of a Lisp hacker who missed them and submitted working patches*. You can use filter to remove elements from the list:

is_not_thing = lambda x: x is not thing
cleaned_list = filter(is_not_thing, some_list)

There is a shortcut that may be useful for your case: if you want to filter out empty items (in fact items where bool(item) == False, like None, zero, empty strings or other empty collections), you can pass None as the first argument:

cleaned_list = filter(None, some_list)

• [update]: in Python 2.x, filter(function, iterable) used to be equivalent to [item for item in iterable if function(item)] (or [item for item in iterable if item] if the first argument is None); in Python 3.x, it is now equivalent to (item for item in iterable if function(item)). The subtle difference is that filter used to return a list, now it works like a generator expression - this is OK if you are only iterating over the cleaned list and discarding it, but if you really need a list, you have to enclose the filter() call with the list() constructor.
• *These Lispy flavored constructs are considered a little alien in Python. Around 2005, Guido was even talking about dropping filter - along with companions map and reduce (they are not gone yet but reduce was moved into the functools module, which is worth a look if you like high order functions).

4) Mathematical style:

List comprehensions became the preferred style for list manipulation in Python since introduced in version 2.0 by PEP 202. The rationale behind it is that List comprehensions provide a more concise way to create lists in situations where map() and filter() and/or nested loops would currently be used.

cleaned_list = [ x for x in some_list if x is not thing ]

Generator expressions were introduced in version 2.4 by PEP 289. A generator expression is better for situations where you don't really need (or want) to have a full list created in memory - like when you just want to iterate over the elements one at a time. If you are only iterating over the list, you can think of a generator expression as a lazy evaluated list comprehension:

for item in (x for x in some_list if x is not thing):
    do_your_thing_with(item)

• See this Python history blog post by GvR.
• This syntax is inspired by the set-builder notation in math.
• Python 3 has also set and dict comprehensions.

Notes

1. you may want to use the inequality operator != instead of is not (the difference is important)
2. for critics of methods implying a list copy: contrary to popular belief, generator expressions are not always more efficient than list comprehensions - please profile before complaining

For example: how to describe concisely in a docstring that a function returns a list of tuples, with each tuple of the form (node_id, node_name, uptime_minutes) and that the elements are respectively a string, string and integer?

Um... There is no "concise" description of this. It's complex. You've designed it to be complex. And it requires complex documentation in the docstring.

Sorry, but complexity is -- well -- complex.

<img id="uxcMyImageId" src"myImage" width="100" height="100" />

specifying width and height in the image tag is a good practice..this way when the page loads there is space allocated for the image and the layout does not suffer any jerks even if the image takes a long time to load.

One of the simple ways:

containerView.setLayoutTransition(LayoutTransition())
containerView.layoutTransition.enableTransitionType(LayoutTransition.CHANGING)

I don't think that replacing "Require all denied" with "Require all granted" in this directive:

<Directory>

    Options FollowSymLinks
    AllowOverride None
    #Require all denied
    Require all granted
</Directory>

as suggested by Jan Czarny and seonded by user3801675 is the most secure way of solving this problem.

According to the Apache configuration files, that line denies access to the entirety of your server's filesystem. Replacing it might indeed allow access to your virtual host folders but at the price of allowing access to your entire computer as well!

Gev Balyan's approach seems to be the most secure approach here. It was the answer to the "access denied problems" plaguing me after setting up my new Apache server this morning.

A stored procedure is mainly used to perform certain tasks on a database. For example

• Get database result sets from some business logic on data.
• Execute multiple database operations in a single call.
• Used to migrate data from one table to another table.
• Can be called for other programming languages, like Java.

Another possible way:

open my $fh, '<', "filename";
read $fh, my $string, -s $fh;
close $fh;

In my case, the application context is not loaded because I add @DataJpaTest annotation. When I change it to @SpringBootTest it works.

@DataJpaTest only loads the JPA part of a Spring Boot application. In the JavaDoc:

Annotation that can be used in combination with @RunWith(SpringRunner.class) for a typical JPA test. Can be used when a test focuses only on JPA components. Using this annotation will disable full auto-configuration and instead apply only configuration relevant to JPA tests.

By default, tests annotated with @DataJpaTest will use an embedded in-memory database (replacing any explicit or usually auto-configured DataSource). The @AutoConfigureTestDatabase annotation can be used to override these settings. If you are looking to load your full application configuration, but use an embedded database, you should consider @SpringBootTest combined with @AutoConfigureTestDatabase rather than this annotation.

Another sample code where you can upload a file to the REST service, the REST service zips the file, and the client downloads the zip file from the server. This is a good example of using binary input and output streams using Jersey.

https://stackoverflow.com/a/32253028/15789

This answer was posted by me in another thread. Hope this helps.

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

Following position parameter worked for me

position: { my: "right bottom", at: "center center", of: window },

Good luck!

So, when using gcc, I like:

#define DBGI(expr) ({int g2rE3=expr; fprintf(stderr, "%s:%d:%s(): ""%s->%i\n", __FILE__,  __LINE__, __func__, #expr, g2rE3); g2rE3;})

Because it can be inserted into code.

Suppose you're trying to debug

printf("%i\n", (1*2*3*4*5*6));

720

Then you can change it to:

printf("%i\n", DBGI(1*2*3*4*5*6));

hello.c:86:main(): 1*2*3*4*5*6->720
720

And you can get an analysis of what expression was evaluated to what.

It's protected against the double-evaluation problem, but the absence of gensyms does leave it open to name-collisions.

However it does nest:

DBGI(printf("%i\n", DBGI(1*2*3*4*5*6)));

hello.c:86:main(): 1*2*3*4*5*6->720
720
hello.c:86:main(): printf("%i\n", DBGI(1*2*3*4*5*6))->4

So I think that as long as you avoid using g2rE3 as a variable name, you'll be OK.

Certainly I've found it (and allied versions for strings, and versions for debug levels etc) invaluable.

int64_t is typedef you can find that in <stdint.h> in C

In your .htaccess you can add:

    php_value memory_limit 64M

If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.

If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

Dynamic (Based on Eilert Hjelmeseths Comment, updated to fix bug( + to -))

SELECT ABS(CHECKSUM(NEWID()) % (@max - @min - 1)) + @min

Updated based on comments:

• NEWID generates random string (for each row in return)
• CHECKSUM takes value of string and creates number
• modulus (%) divides by that number and returns the remainder (meaning max value is one less than the number you use)
• ABS changes negative results to positive
• then add one to the result to eliminate 0 results (to simulate a dice roll)

Use this code:

var result=JsonConvert.DeserializeObject<List<yourObj>>(jsonString);

check ports using bash

Example

$ ./test_port_bash.sh 192.168.7.7 22

the port 22 is open

if [ $? -eq 0 ];then echo "the port $2 is open";else echo "the port $2 is closed";fi

run

sudo find / -name my.cnf

Usually the first result is the correct one. Should be in

/usr/local/etc/

To answer your question with your own suggestion:

>>> [x for b in a for x in b] # Works fine

While you asked for list comprehension answers, let me also point out the excellent itertools.chain():

>>> from itertools import chain
>>> list(chain.from_iterable(a))
>>> list(chain(*a)) # If you're using python < 2.6

Try to add continue; where you want to skip 1 iteration.

Unlike the break keyword, continue does not terminate a loop. Rather, it skips to the next iteration of the loop, and stops executing any further statements in this iteration. This allows us to bypass the rest of the statements in the current sequence, without stopping the next iteration through the loop.

For >= 2nd row values insert into table-

A static variable value persists between different function calls andits scope is limited to the local block a static var always initializes with value 0

As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

The ? and the OR needs to be seperated by a space character. Do it wherever needed in the query string.

This is your safest way to do it:

$id =101;
//$user_id=25;
$criteria=new CDbCriteria;
$criteria->condition="email_id < :email_id";
//$criteria->addCondition("user_id=:user_id");
$criteria->params=array(
  ':email_id' => $id,
  //':user_id' => $user_id,
);
$comments=EmailArchive::model()->findAll($criteria);

Note that if you comment out the commented lines you get a way to add more filtering to your search.

After this it is recommend to check if there is any data returned like:

if (isset($comments)) { // We found some comments, we can sleep well tonight
  // do comments process or whatever
}

You are right that CSS positioning is the way to go. Here's a quick run down:

position: relative will layout an element relative to itself. In other words, the elements is laid out in normal flow, then it is removed from normal flow and offset by whatever values you have specified (top, right, bottom, left). It's important to note that because it's removed from flow, other elements around it will not shift with it (use negative margins instead if you want this behaviour).

However, you're most likely interested in position: absolute which will position an element relative to a container. By default, the container is the browser window, but if a parent element either has position: relative or position: absolute set on it, then it will act as the parent for positioning coordinates for its children.

To demonstrate:

#container {_x000D_
  position: relative;_x000D_
  border: 1px solid red;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
#box {_x000D_
  position: absolute;_x000D_
  top: 50px;_x000D_
  left: 20px;_x000D_
}

<div id="container">_x000D_
  <div id="box">absolute</div>_x000D_
</div>

In that example, the top left corner of #box would be 100px down and 50px left of the top left corner of #container. If #container did not have position: relative set, the coordinates of #box would be relative to the top left corner of the browser view port.

I have just noticed that Bjarne Stroustrup labels % as the remainder operator, not the modulo operator.

I would bet that this is its formal name in the ANSI C & C++ specifications, and that abuse of terminology has crept in. Does anyone know this for a fact?

But if this is the case then C's fmodf() function (and probably others) are very misleading. they should be labelled fremf(), etc

just remove z-index: 1040;

Or you can have your alias in a HAVING clause

Unfortunately, there is a character limit so this will be in many parts. First thing to note is that return and print are statements, not functions, but that is just semantics.

I’ll start with a basic explanation. print just shows the human user a string representing what is going on inside the computer. The computer cannot make use of that printing. return is how a function gives back a value. This value is often unseen by the human user, but it can be used by the computer in further functions.

On a more expansive note, print will not in any way affect a function. It is simply there for the human user’s benefit. It is very useful for understanding how a program works and can be used in debugging to check various values in a program without interrupting the program.

return is the main way that a function returns a value. All functions will return a value, and if there is no return statement (or yield but don’t worry about that yet), it will return None. The value that is returned by a function can then be further used as an argument passed to another function, stored as a variable, or just printed for the benefit of the human user. Consider these two programs:

def function_that_prints():
    print "I printed"

def function_that_returns():
    return "I returned"

f1 = function_that_prints()
f2 = function_that_returns()

print "Now let us see what the values of f1 and f2 are"

print f1 --->None

print f2---->"I returned"

When function_that_prints ran, it automatically printed to the console "I printed". However, the value stored in f1 is None because that function had no return statement.

When function_that_returns ran, it did not print anything to the console. However, it did return a value, and that value was stored in f2. When we printed f2 at the end of the code, we saw "I returned"

This is what worked for me.

I wrote about an alternative in this StackOverflow answer.

There I wrote step by step, explaining with code. The short way:

First: write an object

Second: create a converter to mapping the model extending the AbstractHttpMessageConverter

Third: tell to spring use this converter implementing a WebMvcConfigurer.class overriding the configureMessageConverters method

Fourth and final: using this implementation setting in the mapping inside your controller the consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE and @RequestBody in front of your object.

To replace whole line containing a specified string with the content of that line

Text file:

Row: 0 last_time_contacted=0, display_name=Mozart, _id=100, phonebook_bucket_alt=2
Row: 1 last_time_contacted=0, display_name=Bach, _id=101, phonebook_bucket_alt=2

Single string:

$ sed 's/.* display_name=\([[:alpha:]]\+\).*/\1/'
output:
100
101

Multiple strings delimited by white-space:

$ sed 's/.* display_name=\([[:alpha:]]\+\).* _id=\([[:digit:]]\+\).*/\1 \2/'
output:
Mozart 100
Bach 101

Adjust regex to meet your needs

[:alpha] and [:digit:] are Character Classes and Bracket Expressions

Memory Engine is not the solution you're looking for. You lose everything that you went to a database for in the first place (i.e. ACID).

Here are some better alternatives:

1. Don't use joins - very few large apps do this (i.e Google, Flickr, NetFlix), because it sucks for large sets of joins.

A LEFT [OUTER] JOIN can be faster than an equivalent subquery because the server might be able to optimize it better—a fact that is not specific to MySQL Server alone.

-The MySQL Manual

2. Make sure the columns you're querying against have indexes. Use EXPLAIN to confirm they are being used.
3. Use and increase your Query_Cache and memory space for your indexes to get them in memory and store frequent lookups.
4. Denormalize your schema, especially for simple joins (i.e. get fooId from barMap).

The last point is key. I used to love joins, but then had to run joins on a few tables with 100M+ rows. No good. Better off insert the data you're joining against into that target table (if it's not too much) and query against indexed columns and you'll get your query in a few ms.

I hope those help.

The problem is that your class contains a managed RAW pointer but does not implement the rule of three (five in C++11). As a result you are getting (expectedly) a double delete because of copying.

If you are learning you should learn how to implement the rule of three (five). But that is not the correct solution to this problem. You should be using standard container objects rather than try to manage your own internal container. The exact container will depend on what you are trying to do but std::vector is a good default (and you can change afterwords if it is not opimal).

#include <queue>
#include <vector>

class Test{
    std::vector<int> myArray;

    public:
    Test(): myArray(10){
    }    
};

int main(){
    queue<Test> q
    Test t;
    q.push(t);
}

The reason you should use a standard container is the separation of concerns. Your class should be concerned with either business logic or resource management (not both). Assuming Test is some class you are using to maintain some state about your program then it is business logic and it should not be doing resource management. If on the other hand Test is supposed to manage an array then you probably need to learn more about what is available inside the standard library.

html, body {
    height: 100%;
    width: 100%;
}

html {
    display: table;
    margin: auto;
}

body {
    padding-top: 50px;
    display: table-cell;
}

div {
    margin: auto;
}

This will center align objects and then also center align the items within them to center align multiple objects with different widths.

Example picture

This should be a comment, but comments don't allow multi-line code.

Here's what's happening:

in Event.cpp

#include "Event.h"

preprocessor starts processing Event.h

#ifndef EVENT_H_

it isn't defined yet, so keep going

#define EVENT_H_
#include "common.h"

common.h gets processed ok

#include "Item.h"

Item.h gets processed ok

#include "Flight.h"

Flight.h gets processed ok

#include "Landing.h"

preprocessor starts processing Landing.h

#ifndef LANDING_H_

not defined yet, keep going

#define LANDING_H_

#include "Event.h"

preprocessor starts processing Event.h

#ifndef EVENT_H_

This IS defined already, the whole rest of the file gets skipped. Continuing with Landing.h

class Landing: public Event {

The preprocessor doesn't care about this, but the compiler goes "WTH is Event? I haven't heard about Event yet."

Why use the rewrite module if you can do return? Technically speaking, return is part of the rewrite module as you can read here but this snippet is easier to read imho.

server {
    server_name  .domain.com;

    return 302 $scheme://forwarded-domain.com;
}

You can also give it a 301 redirect.

If I understand what you need, try this:

SELECT id, pass, AVG(val) AS val_1 
FROM data_r1 
GROUP BY id, pass;

Or, if you want just one row for every id, this:

SELECT d1.id,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 1) as val_1,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 2) as val_2,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 3) as val_3,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 4) as val_4,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 5) as val_5,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 6) as val_6,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 7) as val_7
from data_r1 d1
GROUP BY d1.id

It can't be done directly, but you can emulate the same thing using function pointers and explicitly passing the "this" parameter:

typedef struct client_t client_t, *pno;
struct client_t
{
        pid_t pid;
        char password[TAM_MAX]; // -> 50 chars
        pno next;

        pno (*AddClient)(client_t *);    
};

pno client_t_AddClient(client_t *self) { /* code */ }

int main()
{

    client_t client;
    client.AddClient = client_t_AddClient; // probably really done in some init fn

    //code ..

    client.AddClient(&client);

}

It turns out that doing this, however, doesn't really buy you an awful lot. As such, you won't see many C APIs implemented in this style, since you may as well just call your external function and pass the instance.

If you have your backend and database started on docker

Instead of putting localhost or 127.0.0.1 as DB_HOST put the name of the registered service that indicates your database service in the docker-compose file.

In my case for example I replaced 127.0.0.1 with db because in my docker-compose file I had defined the name of the service for the database as db

My docker-compose looks something like that

services:
    db: <------ This is the name of the DB_HOST
      container_name: admin_db
      image:mysql:5.7.22
    .
    .
    .

Your resource probably use a self-signed SSL certificate over HTTPS protocol. Chromium, so Google Chrome block by default this kind of resource considered unsecure.

You can bypass this this way :

• Assuming your frame's URL is https://www.domain.com, open a new tab in chrome and go to https://www.domain.com.
• Chrome will ask you to accept the SSL certificate. Accept it.
• Then, if you reload your page with your frame, you could see that now it works

The problem as you can guess, is that each visitor of your website has to do this task to access your frame.

You can notice that chrome will block your URL for each navigation session, while chrome can memorise for ever that you trust this domain.

If your frame can be accessed by HTTP rather than HTTPS, I suggest you to use it, so this problem will be solved.

If data already exists in the column you should do:

ALTER TABLE tbl_name ALTER COLUMN col_name TYPE integer USING col_name::integer;

As pointed out by @nobu and @jonathan-porter in comments to @derek-kromm's answer.

[Test double types]

Mock vs Spy

Mock is a bare double object. This object has the same methods signatures but realisation is empty and return default value - 0 and null

Spy is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it

class A {
    String foo1() {
        foo2();
        return "RealString_1";
    }

    String foo2() {
        return "RealString_2";
    }

    void foo3() { foo4(); }

    void foo4() { }
}

@Test
public void testMockA() {
    //given

    Mockito.when(mockA.foo1()).thenReturn("MockedString");

    //when
    String result1 = mockA.foo1();
    String result2 = mockA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals(null, result2);

    //Case 2
    //when
    mockA.foo3();

    //then
    verify(mockA).foo3();
    verify(mockA, never()).foo4();
}

@Test
public void testSpyA() {
    //given
    A spyA = Mockito.spy(new A());

    Mockito.when(spyA.foo1()).thenReturn("MockedString");

    //when
    String result1 = spyA.foo1();
    String result2 = spyA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals("RealString_2", result2);

    //Case 2
    //when
    spyA.foo3();

    //then
    verify(spyA).foo3();
    verify(spyA).foo4();
}

You can do it without using lodash.

let arr = [{id: 1, name: "Person 1"}, {id: 2, name: "Person 2"}];
let newObj = {id: 1, name: "new Person"}

/*Add new prototype function on Array class*/
Array.prototype._replaceObj = function(newObj, key) {
  return this.map(obj => (obj[key] === newObj[key] ? newObj : obj));
};

/*return [{id: 1, name: "new Person"}, {id: 2, name: "Person 2"}]*/
arr._replaceObj(newObj, "id") 

This often happens when you modify a c function definition and forget to update the corresponding header definition.

This can also be achieved with itertools.chain.from_iterable which will flatten the consecutive iterables:

import itertools
for item in itertools.chain.from_iterable(iterables):
    # do something with item    

Your code isn't working, because the hidden attibute is not supported in versions of IE before v11

If you need to support IE before version 11, add a CSS style to hide when the hidden attribute is present:

*[hidden] { display: none; }

If you are struggling with authenticating to a site, and Maven is caching the results, simply removing the meta-data about the site from the meta-data stash will force Maven to revisit the site.

Wow, the answers are all over the map. So the Documentation says:

A FOREIGN KEY constraint is a candidate for an index because:

• Changes to PRIMARY KEY constraints are checked with FOREIGN KEY constraints in related tables.

• Foreign key columns are often used in join criteria when the data from related tables is combined in queries by matching the column(s) in the FOREIGN KEY constraint of one table with the primary or unique key column(s) in the other table. An index allows Microsoft® SQL Server™ 2000 to find related data in the foreign key table quickly. However, creating this index is not a requirement. Data from two related tables can be combined even if no PRIMARY KEY or FOREIGN KEY constraints are defined between the tables, but a foreign key relationship between two tables indicates that the two tables have been optimized to be combined in a query that uses the keys as its criteria.

So it seems pretty clear (although the documentation is a bit muddled) that it does not in fact create an index.

This should do the trick:

import pandas as pd
import pymysql
pymysql.install_as_MySQLdb()
from sqlalchemy import create_engine

# Create engine
engine = create_engine('mysql://USER_NAME_HERE:PASS_HERE@HOST_ADRESS_HERE/DB_NAME_HERE')

# Create the connection and close it(whether successed of failed)
with engine.begin() as connection:
  df.to_sql(name='INSERT_TABLE_NAME_HERE/INSERT_NEW_TABLE_NAME', con=connection, if_exists='append', index=False)

That probably means that your id is an AUTO_INCREMENT integer and you're trying to send a string. You should specify a column list and omit it from your INSERT.

INSERT INTO workorders (column1, column2) VALUES ($column1, $column2)

You need to add -L/opt/lib to tell ld to look there for shared objects.

You can pass a binding of

{'n' : range(n) }

to the template, then do

{% for i in n %}
...
{% endfor %}

Note that you'll get 0-based behavior (0, 1, ... n-1).

There are two branches lets say

• A (Branch on which you are working)
• B (Another branch with which you want to compare)

Being in branch A you can type

git diff --color B

then this will give you a output of

The important point about this is

1. Text in green is inside present in Branch A

2. Text in red is present in Branch B

importlib.import_module is what you are looking for. It returns the imported module. (Only available for Python >= 2.7 or 3.x):

import importlib

mymodule = importlib.import_module('matplotlib.text')

You can thereafter access anything in the module as mymodule.myclass, etc.

There is a way to get count of runes without any packages by converting string to []rune as len([]rune(YOUR_STRING)):

package main

import "fmt"

func main() {
    russian := "??????? ? ??????"
    english := "Sputnik & pogrom"

    fmt.Println("count of bytes:",
        len(russian),
        len(english))

    fmt.Println("count of runes:",
        len([]rune(russian)),
        len([]rune(english)))

}

count of bytes 30 16

count of runes 16 16

For an English dictionary .txt file, you can use Custom Dictionary.

You can also generate a list aspell or wordlist with own settings.

Also you can take a look at http://wordlist.sourceforge.net/

Look at the following example code:

public class MyWorker
{
    public SharedData state;
    public void DoWork(SharedData someData)
    {
        this.state = someData;
        while (true) ;
    }

}

public class SharedData {
    X myX;
    public getX() { etc
    public setX(anX) { etc

}

public class Program
{
    public static void Main()
    {
        SharedData data = new SharedDate()
        MyWorker work1 = new MyWorker(data);
        MyWorker work2 = new MyWorker(data);
        Thread thread = new Thread(new ThreadStart(work1.DoWork));
        thread.Start();
        Thread thread2 = new Thread(new ThreadStart(work2.DoWork));
        thread2.Start();
    }
}

In this case, the thread class MyWorker has a variable state. We initialise it with the same object. Now you can see that the two workers access the same SharedData object. Changes made by one worker are visible to the other.

You have quite a few remaining issues. How does worker 2 know when changes have been made by worker 1 and vice-versa? How do you prevent conflicting changes? Maybe read: this tutorial.

Use the function IF :

=IF ( logical_test, value_if_true, value_if_false )

Here's how I would do this:

class ClassPropertyDescriptor(object):

    def __init__(self, fget, fset=None):
        self.fget = fget
        self.fset = fset

    def __get__(self, obj, klass=None):
        if klass is None:
            klass = type(obj)
        return self.fget.__get__(obj, klass)()

    def __set__(self, obj, value):
        if not self.fset:
            raise AttributeError("can't set attribute")
        type_ = type(obj)
        return self.fset.__get__(obj, type_)(value)

    def setter(self, func):
        if not isinstance(func, (classmethod, staticmethod)):
            func = classmethod(func)
        self.fset = func
        return self

def classproperty(func):
    if not isinstance(func, (classmethod, staticmethod)):
        func = classmethod(func)

    return ClassPropertyDescriptor(func)


class Bar(object):

    _bar = 1

    @classproperty
    def bar(cls):
        return cls._bar

    @bar.setter
    def bar(cls, value):
        cls._bar = value


# test instance instantiation
foo = Bar()
assert foo.bar == 1

baz = Bar()
assert baz.bar == 1

# test static variable
baz.bar = 5
assert foo.bar == 5

# test setting variable on the class
Bar.bar = 50
assert baz.bar == 50
assert foo.bar == 50

The setter didn't work at the time we call Bar.bar, because we are calling TypeOfBar.bar.__set__, which is not Bar.bar.__set__.

Adding a metaclass definition solves this:

class ClassPropertyMetaClass(type):
    def __setattr__(self, key, value):
        if key in self.__dict__:
            obj = self.__dict__.get(key)
        if obj and type(obj) is ClassPropertyDescriptor:
            return obj.__set__(self, value)

        return super(ClassPropertyMetaClass, self).__setattr__(key, value)

# and update class define:
#     class Bar(object):
#        __metaclass__ = ClassPropertyMetaClass
#        _bar = 1

# and update ClassPropertyDescriptor.__set__
#    def __set__(self, obj, value):
#       if not self.fset:
#           raise AttributeError("can't set attribute")
#       if inspect.isclass(obj):
#           type_ = obj
#           obj = None
#       else:
#           type_ = type(obj)
#       return self.fset.__get__(obj, type_)(value)

Now all will be fine.

Just use DOMDocument->loadHTML() and be done with it. libxml's HTML parsing algorithm is quite good and fast, and contrary to popular belief, does not choke on malformed HTML.

Yes, use the commercial but inexpensive SSMS Tools Pack addin which has a nifty "Generate Insert statements from resultsets, tables or database" feature

Kotlin code:

Start the SecondActivity:

startActivity(Intent(context, SecondActivity::class.java)
    .putExtra(SecondActivity.PARAM_GAME_ID, gameId))

Get the Id in SecondActivity:

class CaptureActivity : AppCompatActivity() {

    companion object {
        const val PARAM_GAME_ID = "PARAM_GAME_ID"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val gameId = intent.getStringExtra(PARAM_GAME_ID)
        // TODO use gameId
    }
}

where gameId is String? (can be null)

Yes, why not? Then CSS that applies to class "x" AND CSS that applies to ID "y" applies to the div.

Quick Answer

Use different methods to load the form and save/process form.

Example.

Login.php

Load login form at Login/index Validate login at Login/validate

On Success

Redirect the user to User/dashboard

On failure

Redirect the user to login/index

You could do:

$posted = preg_replace('/ By.*/', '', $posted);
echo $posted;

If you want to select ALL(columns) data as distinct frrom a DataFrame (df), then

df.select('*').distinct().show(10,truncate=False)

I'm lacking context, but this is working just fine:

List<BigInteger> nums = new ArrayList<BigInteger>();
Long max = Collections.max(nums).longValue(); // from BigInteger to Long...

This query should work for you:

SELECT *
FROM table
WHERE MONTH(columnName) = MONTH(CURRENT_DATE())
AND YEAR(columnName) = YEAR(CURRENT_DATE())

try this css:

/* Show in default resolution screen*/
#container2 {
width: 960px;
position: relative;
margin:0 auto;
line-height: 1.4em;
}

/* If in mobile screen with maximum width 479px. The iPhone screen resolution is 320x480 px (except iPhone4, 640x960) */    
@media only screen and (max-width: 479px){
    #container2 { width: 90%; }
}

If you're using it in several different places, you should turn it into a plugin.

jQuery.fn.fadeOutAndRemove = function(speed){
    $(this).fadeOut(speed,function(){
        $(this).remove();
    })
}

And then:

// Somewhere in the program code.
$('div').fadeOutAndRemove('fast');

I tried for a very long time to duplicate tabs in Chrome running using action_keys and send_keys on body. The only thing that worked for me was an answer here. This is what my duplicate tabs def ended up looking like, probably not the best but it works fine for me.

def duplicate_tabs(number, chromewebdriver):
#Once on the page we want to open a bunch of tabs
url = chromewebdriver.current_url
for i in range(number):
    print('opened tab: '+str(i))
    chromewebdriver.execute_script("window.open('"+url+"', 'new_window"+str(i)+"')")

It basically runs some java from inside of python, it's incredibly useful. Hope this helps somebody.

Note: I am using Ubuntu, it shouldn't make a difference but if it doesn't work for you this could be the reason.

The simplest & least error prone approach is... Use Calendar's roll() method. Like this:

    c.roll(Calendar.MONTH, false);

the roll method takes a boolean, which basically means roll the month up(true) or down(false)?

It seems to me that simply: ls -lt mydirectory does the job...

You can convert the string to integer using Convert.ToInt32() function

int intTemp = Convert.ToInt32(Console.ReadLine());

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

A simple solution is to use Microsoft ASP.NET Web API 2.2 Client from NuGet.

Then you can simply do this and it'll serialize the object to JSON and set the Content-Type header to application/json; charset=utf-8:

var data = new
{
    name = "Foo",
    category = "article"
};

var client = new HttpClient();
client.BaseAddress = new Uri(baseUri);
client.DefaultRequestHeaders.Add("token", token);
var response = await client.PostAsJsonAsync("", data);

You have a type-o:

its: height: 200x;

and it should be: height: 200px; also check the image url; it should be in the same directory it seems.

Also, dont use 'px' at null (aka '0') values. 0px, 0em, 0% is still 0. :)

top: 0px;

is the same with:

top: 0;

Good Luck!

You want to use "multiline".

$string =~ /(START)(.+?)(END)/m;

Although this question is old, it is still relevant for my more or less up-to-date system. After enabling debug mode of sudo (Debug sudo /var/log/sudo_debug all@info in /etc/sudo.conf) I was pointed to /dev: "/dev is world writable". So you might need to check the tty file permissions, especially those of the directory where the tty/pts node resides in.

I'd print out the result of an2.getNodeName() as well for debugging purposes. My guess is that your tree crawling code isn't crawling to the nodes that you think it is. That suspicion is enhanced by the lack of checking for node names in your code.

Other than that, the javadoc for Node defines "getNodeValue()" to return null for Nodes of type Element. Therefore, you really should be using getTextContent(). I'm not sure why that wouldn't give you the text that you want.

Perhaps iterate the children of your tag node and see what types are there?

Tried this code and it works for me:

String xml = "<add job=\"351\">\n" +
             "    <tag>foobar</tag>\n" +
             "    <tag>foobar2</tag>\n" +
             "</add>";
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
ByteArrayInputStream bis = new ByteArrayInputStream(xml.getBytes());
Document doc = db.parse(bis);
Node n = doc.getFirstChild();
NodeList nl = n.getChildNodes();
Node an,an2;

for (int i=0; i < nl.getLength(); i++) {
    an = nl.item(i);
    if(an.getNodeType()==Node.ELEMENT_NODE) {
        NodeList nl2 = an.getChildNodes();

        for(int i2=0; i2<nl2.getLength(); i2++) {
            an2 = nl2.item(i2);
            // DEBUG PRINTS
            System.out.println(an2.getNodeName() + ": type (" + an2.getNodeType() + "):");
            if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getTextContent());
            if(an2.hasChildNodes()) System.out.println(an2.getFirstChild().getNodeValue());
            System.out.println(an2.getTextContent());
            System.out.println(an2.getNodeValue());
        }
    }
}

Output was:

#text: type (3): foobar foobar
#text: type (3): foobar2 foobar2

# select columns containing 'spike'
df.filter(like='spike', axis=1)

You can also select by name, regular expression. Refer to: pandas.DataFrame.filter

Using the Google Maps API V3, create a Circle object, then use bindTo() to tie it to the position of your Marker (since they are both google.maps.MVCObject instances).

// Create marker 
var marker = new google.maps.Marker({
  map: map,
  position: new google.maps.LatLng(53, -2.5),
  title: 'Some location'
});

// Add circle overlay and bind to marker
var circle = new google.maps.Circle({
  map: map,
  radius: 16093,    // 10 miles in metres
  fillColor: '#AA0000'
});
circle.bindTo('center', marker, 'position');

You can make it look just like the Google Latitude circle by changing the fillColor, strokeColor, strokeWeight etc (full API).

The core problem seems to be you are opening a window to show a page whose content is already cached in the browser. Therefore no loading happens and therefore no load-event happens.

One possibility could be to use the 'pageshow' -event instead, as described in:

As a commenter mentioned you can get Values from net/url which has an Encode method. You could do something like this (req.URL.Query() returns the existing url.Values)

package main

import (
    "fmt"
    "log"
    "net/http"
    "os"
)

func main() {
    req, err := http.NewRequest("GET", "http://api.themoviedb.org/3/tv/popular", nil)
    if err != nil {
        log.Print(err)
        os.Exit(1)
    }

    q := req.URL.Query()
    q.Add("api_key", "key_from_environment_or_flag")
    q.Add("another_thing", "foo & bar")
    req.URL.RawQuery = q.Encode()

    fmt.Println(req.URL.String())
    // Output:
    // http://api.themoviedb.org/3/tv/popular?another_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}

You are looking for dynamic_cast<B*>(pointer)

Below code will list directories and the files within the dir. The other one is os.walk

def print_directory_contents(sPath):
        import os                                       
        for sChild in os.listdir(sPath):                
            sChildPath = os.path.join(sPath,sChild)
            if os.path.isdir(sChildPath):
                print_directory_contents(sChildPath)
            else:
                print(sChildPath)

AFAIK there isn't a way to do this. You could use a dashed border or perhaps increase the width of the border a bit, but just getting more spaced out dots is impossible with CSS.

ETA 24 Apr 17 I wanted to simplify this a bit with some async/await magic, as it makes it a lot more succinct:

Using the same promisified-observable:

const startObservable = (domNode) => {
  var targetNode = domNode;

  var observerConfig = {
    attributes: true,
    childList: true,
    characterData: true
  };

  return new Promise((resolve) => {
      var observer = new MutationObserver(function (mutations) {
         // For the sake of...observation...let's output the mutation to console to see how this all works
         mutations.forEach(function (mutation) {
             console.log(mutation.type);
         });
         resolve(mutations)
     });
     observer.observe(targetNode, observerConfig);
   })
} 

Your calling function can be as simple as:

const waitForMutation = async () => {
    const button = document.querySelector('.some-button')
    if (button !== null) button.click()
    try {
      const results = await startObservable(someDomNode)
      return results
    } catch (err) { 
      console.error(err)
    }
}

If you wanted to add a timeout, you could use a simple Promise.race pattern as demonstrated here:

const waitForMutation = async (timeout = 5000 /*in ms*/) => {
    const button = document.querySelector('.some-button')
    if (button !== null) button.click()
    try {

      const results = await Promise.race([
          startObservable(someDomNode),
          // this will throw after the timeout, skipping 
          // the return & going to the catch block
          new Promise((resolve, reject) => setTimeout(
             reject, 
             timeout, 
             new Error('timed out waiting for mutation')
          )
       ])
      return results
    } catch (err) { 
      console.error(err)
    }
}

Original

You can do this without libraries, but you'd have to use some ES6 stuff, so be cognizant of compatibility issues (i.e., if your audience is mostly Amish, luddite or, worse, IE8 users)

First, we'll use the MutationObserver API to construct an observer object. We'll wrap this object in a promise, and resolve() when the callback is fired (h/t davidwalshblog)david walsh blog article on mutations:

const startObservable = (domNode) => {
    var targetNode = domNode;

    var observerConfig = {
        attributes: true,
        childList: true,
        characterData: true
    };

    return new Promise((resolve) => {
        var observer = new MutationObserver(function (mutations) {
            // For the sake of...observation...let's output the mutation to console to see how this all works
            mutations.forEach(function (mutation) {
                console.log(mutation.type);
            });
            resolve(mutations)
        });
        observer.observe(targetNode, observerConfig);
    })
} 

Then, we'll create a generator function. If you haven't used these yet, then you're missing out--but a brief synopsis is: it runs like a sync function, and when it finds a yield <Promise> expression, it waits in a non-blocking fashion for the promise to be fulfilled (Generators do more than this, but this is what we're interested in here).

// we'll declare our DOM node here, too
let targ = document.querySelector('#domNodeToWatch')

function* getMutation() {
    console.log("Starting")
    var mutations = yield startObservable(targ)
    console.log("done")
}

A tricky part about generators is they don't 'return' like a normal function. So, we'll use a helper function to be able to use the generator like a regular function. (again, h/t to dwb)

function runGenerator(g) {
    var it = g(), ret;

    // asynchronously iterate over generator
    (function iterate(val){
        ret = it.next( val );

        if (!ret.done) {
            // poor man's "is it a promise?" test
            if ("then" in ret.value) {
                // wait on the promise
                ret.value.then( iterate );
            }
            // immediate value: just send right back in
            else {
                // avoid synchronous recursion
                setTimeout( function(){
                    iterate( ret.value );
                }, 0 );
            }
        }
    })();
}

Then, at any point before the expected DOM mutation might happen, simply run runGenerator(getMutation).

Now you can integrate DOM mutations into a synchronous-style control flow. How bout that.

• Queuing If a request is queued it indicated that:
  • The request was postponed by the rendering engine because it's considered lower priority than critical resources (such as scripts/styles). This often happens with images.
  • The request was put on hold to wait for an unavailable TCP socket that's about to free up.
  • The request was put on hold because the browser only allows six TCP connections per origin on HTTP 1. Time spent making disk cache entries (typically very quick.)
• Stalled/Blocking Time the request spent waiting before it could be sent. It can be waiting for any of the reasons described for Queueing. Additionally, this time is inclusive of any time spent in proxy negotiation.

Exactly what Pekka said...

Alternatively, you can probably use array_merge like this if you wanted:

array_merge($_GET, array($rule[0] => $rule[1]));

But I'd prefer Pekka's method probably as it is much simpler.

This should work in C++11 without boost:

namespace std {
template<class T>
T begin(std::pair<T, T> p)
{
    return p.first;
}
template<class T>
T end(std::pair<T, T> p)
{
    return p.second;
}
}

template<class Iterator>
std::reverse_iterator<Iterator> make_reverse_iterator(Iterator it)
{
    return std::reverse_iterator<Iterator>(it);
}

template<class Range>
std::pair<std::reverse_iterator<decltype(begin(std::declval<Range>()))>, std::reverse_iterator<decltype(begin(std::declval<Range>()))>> make_reverse_range(Range&& r)
{
    return std::make_pair(make_reverse_iterator(begin(r)), make_reverse_iterator(end(r)));
}

for(auto x: make_reverse_range(r))
{
    ...
}
