You can save your graph as svg for a lossless quality:

import matplotlib.pylab as plt

x = range(10)

plt.figure()
plt.plot(x,x)
plt.savefig("graph.svg")

This message digital envelope routines: EVP_DecryptFInal_ex: bad decrypt can also occur when you encrypt and decrypt with an incompatible versions of openssl.

The issue I was having was that I was encrypting on Windows which had version 1.1.0 and then decrypting on a generic Linux system which had 1.0.2g.

It is not a very helpful error message!

Working solution:

A possible solution from @AndrewSavinykh that worked for many (see the comments):

Default digest has changed between those versions from md5 to sha256. One can specify the default digest on the command line as -md sha256 or -md md5 respectively

I also faced the same problem and

remove.packages(c("ggplot2", "data.table"))
install.packages('Rcpp', dependencies = TRUE)
install.packages('ggplot2', dependencies = TRUE)

these commands did not work for me. What I found was that it was showing a warning message that it could not move temporary installation C:\Users\User_name\Documents\R\win-library\3.3\abcd1234\Rcpp to C:\Users\User_name\Documents\R\win-library\3.3\Rcpp.

I downloaded the Rcpp zip file from the link given and unziped it and copied it inside C:\Users\User_name\Documents\R\win-library\3.3 and then

library(Rcpp)
library(ggplot2) 

worked. I did not have to uninstall R. Hope this helps.

As @avp says the bash line pip install seaborn should work I just had the same problem and and restarting the notebook didn't seem to work but running the command as jupyter line magic was a neat way to fix the problem without restarting the notebook

Jupyter Code-Cell:

%%bash
pip install seaborn

The first argument is the file you wish to execute, and the second argument is an array of null-terminated strings that represent the appropriate arguments to the file as specified in the man page.

For example:

char *cmd = "ls";
char *argv[3];
argv[0] = "ls";
argv[1] = "-la";
argv[2] = NULL;

execvp(cmd, argv); //This will run "ls -la" as if it were a command

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

class MyHandler(FileSystemEventHandler):

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

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

This is what I finally could do for installing psych package in R-3.4.1 when I got the same warning

1:Googled for that package.

2:downloaded it manually having tar.gz extension

3:Chose the option "Package Archive File (.zip;.tar.gz)" for install packages in R

4:browsed locally to the place where it was downloaded and clicked install

You may get a warning: dependencies 'xyz' not available for the package ,then first install those from the repository and then do steps 3-4 .

You can use top_n

df %>% group_by(A, B) %>% top_n(n=1)

This will rank by the last column (value) and return the top n=1 rows.

Currently, you can't change the this default without causing an error (See https://github.com/hadley/dplyr/issues/426)

Here is a working exemple :

printf("-%s-", (char[2]){'A', 0});

This will display -A-

You could try this:

int lengthChar(const char* chararray) {
   int n = 0;
   while(chararray[n] != '\0')
     n ++;
   return n;  
}

First of all this code snippet

char *addr=NULL;
strcpy(addr,retstring().c_str());

is invalid because you did not allocate memory where you are going to copy retstring().c_str().

As for the error message then it is clear enough. The type of expression data.str().c_str() is const char * but the third parameter of the function is declared as char *. You may not assign an object of type const char * to an object of type char *. Either the function should define the third parameter as const char * if it does not change the object pointed by the third parameter or you may not pass argument of type const char *.

char ch = 't';
char chArray[2];
sprintf(chArray, "%c", ch);
char chOutput[10]="tes";
strcat(chOutput, chArray);
cout<<chOutput;

OUTPUT:

test

I have a sample program for this:

public class BrowserBackForward {

/**
 * @param args
 * @throws InterruptedException 
 */
public static void main(String[] args) throws InterruptedException {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://seleniumhq.org/");
    driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    //maximize the window
    driver.manage().window().maximize();

    driver.findElement(By.linkText("Documentation")).click();
    System.out.println(driver.getCurrentUrl());
    driver.navigate().back();
    System.out.println(driver.getCurrentUrl());
    Thread.sleep(30000);
    driver.navigate().forward();
    System.out.println("Forward");
    Thread.sleep(30000);
    driver.navigate().refresh();

}

}

Sometimes it is just easier to start over... I apologize if there is any typo, I haven't had the time to test it thoroughly.

Set your SMTP auth to true if using the PHPmailer class:

$mail->SMTPAuth = true;

numpy.linspace() gives you a one-dimensional NumPy array. For example:

>>> my_array = numpy.linspace(1, 10, 10)
>>> my_array
array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.])

Therefore:

for index,point in my_array

cannot work. You would need some kind of two-dimensional array with two elements in the second dimension:

>>> two_d = numpy.array([[1, 2], [4, 5]])
>>> two_d
array([[1, 2], [4, 5]])

Now you can do this:

>>> for x, y in two_d:
    print(x, y)

1 2
4 5

Even more simple if you accept using pandas :

import pandas
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}
df = pandas.DataFrame(result, index=[0])
print df

gives :

          0         1         2         3  4         5         6
0  1.118175  0.556608  0.471827  0.487167  1  0.139508  0.209416

C does not and never has had a native string type. By convention, the language uses arrays of char terminated with a null char, i.e., with '\0'. Functions and macros in the language's standard libraries provide support for the null-terminated character arrays, e.g., strlen iterates over an array of char until it encounters a '\0' character and strcpy copies from the source string until it encounters a '\0'.

The use of null-terminated strings in C reflects the fact that C was intended to be only a little more high-level than assembly language. Zero-terminated strings were already directly supported at that time in assembly language for the PDP-10 and PDP-11.

It is worth noting that this property of C strings leads to quite a few nasty buffer overrun bugs, including serious security flaws. For example, if you forget to null-terminate a character string passed as the source argument to strcpy, the function will keep copying sequential bytes from whatever happens to be in memory past the end of the source string until it happens to encounter a 0, potentially overwriting whatever valuable information follows the destination string's location in memory.

In your code example, the string literal "Hello, world!" will be compiled into a 14-byte long array of char. The first 13 bytes will hold the letters, comma, space, and exclamation mark and the final byte will hold the null-terminator character '\0', automatically added for you by the compiler. If you were to access the array's last element, you would find it equal to 0. E.g.:

const char foo[] = "Hello, world!";
assert(foo[12] == '!');
assert(foo[13] == '\0');

However, in your example, message is only 10 bytes long. strcpy is going to write all 14 bytes, including the null-terminator, into memory starting at the address of message. The first 10 bytes will be written into the memory allocated on the stack for message and the remaining four bytes will simply be written on to the end of the stack. The consequence of writing those four extra bytes onto the stack is hard to predict in this case (in this simple example, it might not hurt a thing), but in real-world code it usually leads to corrupted data or memory access violation errors.

At any channel page with "user" url for example http://www.youtube.com/user/klauskkpm, without API call, from YouTube UI, click a video of the channel (in its "VIDEOS" tab) and click the channel name on the video. Then you can get to the page with its "channel" url for example https://www.youtube.com/channel/UCfjTOrCPnAblTngWAzpnlMA.

Because you defined the struct as consisting of char arrays, the two strings are the structure and freeing the struct is sufficient, nor is there a way to free the struct but keep the arrays. For that case you would want to do something like struct { char *firstName, *lastName; }, but then you need to allocate memory for the names separately and handle the question of when to free that memory.

Aside: Is there a reason you want to keep the names after the struct has been freed?

strcpy example:

#include <stdio.h>
#include <string.h>

int main ()
{
  char str1[]="Sample string" ;
  char str2[40] ;
  strcpy (str2,str1) ;
  printf ("str1: %s\n",str1) ;
  return 0 ;
}

Output: str1: Sample string

Your case:

A simple = operator should do the job.

string str1="Sample string" ;
string str2 = str1 ;

You can also do this globally via a rcParams dictionary:

import matplotlib.pylab as pylab
params = {'legend.fontsize': 'x-large',
          'figure.figsize': (15, 5),
         'axes.labelsize': 'x-large',
         'axes.titlesize':'x-large',
         'xtick.labelsize':'x-large',
         'ytick.labelsize':'x-large'}
pylab.rcParams.update(params)

a is defined locally in the function, and can't be used outside the function. If you want to return a char array from the function, you'll need to allocate it dynamically:

char *a = malloc(1000);

And at some point call free on the returned pointer.

You should also see a warning at this line: char b = "blah";: you're trying to assign a string literal to a char.

There's an explanation and solution for this on MSDN:

The function strcpy is considered unsafe due to the fact that there is no bounds checking and can lead to buffer overflow.

Consequently, as it suggests in the error description, you can use strcpy_s instead of strcpy:

strcpy_s( char *strDestination, size_t numberOfElements,
const char *strSource );

and:

Go to Path C:\ProgramData\Oracle\Java\javapath (This path is in my case might be different in your case). Rename the folder ORACLE with other name line ORACLE_OLD. And Restart the STS/IDE . This works for me

You could just use an even simpler typedef:

typedef char *string;

Then, your malloc would look like a usual malloc:

string s = malloc(maxStringLength);

Another solution might look like this,

char arr[] = "mom";
std::cout << "hi " << std::string(arr);

which avoids using an extra variable.

string literals are non-modifiable in C

There is also another possible source of this error. In some J2EE / web containers (in my experience under Jboss 7.x and Tomcat 7.x) You have to add each class You want to use as a hibernate Entity into the file persistence.xml as

<class>com.yourCompanyName.WhateverEntityClass</class>

In case of jboss this concerns every entity class (local - i.e. within the project You are developing or in a library). In case of Tomcat 7.x this concerns only entity classes within libraries.

Two other ways are strcpy(str, ""); and string[0] = 0

To really delete the Variable contents (in case you have dirty code which is not working properly with the snippets above :P ) use a loop like in the example below.

#include <string.h>

...

int i=0;
for(i=0;i<strlen(string);i++)
{
    string[i] = 0;
}

In case you want to clear a dynamic allocated array of chars from the beginning, you may either use a combination of malloc() and memset() or - and this is way faster - calloc() which does the same thing as malloc but initializing the whole array with Null.

At last i want you to have your runtime in mind. All the way more, if you're handling huge arrays (6 digits and above) you should try to set the first value to Null instead of running memset() through the whole String.

It may look dirtier at first, but is way faster. You just need to pay more attention on your code ;)

I hope this was useful for anybody ;)

Use strncpy

e.g.

strncpy(dest, src + beginIndex, endIndex - beginIndex);

This assumes you've

1. Validated that dest is large enough.
2. endIndex is greater than beginIndex
3. beginIndex is less than strlen(src)
4. endIndex is less than strlen(src)

Given that your strings are all fixed-length (presumably at compile-time?), you can do the following:

char (*orderedIds)[ID_LEN+1]
    = malloc(variableNumberOfElements * sizeof(*orderedIds));

// Clear-up
free(orderedIds);

A more cumbersome, but more general, solution, is to assign an array of pointers, and psuedo-initialising them to point at elements of a raw backing array:

char *raw = malloc(variableNumberOfElements * (ID_LEN + 1));
char **orderedIds = malloc(sizeof(*orderedIds) * variableNumberOfElements);

// Set each pointer to the start of its corresponding section of the raw buffer.
for (i = 0; i < variableNumberOfElements; i++)
{
    orderedIds[i] = &raw[i * (ID_LEN+1)];
}

...

// Clear-up pointer array
free(orderedIds);
// Clear-up raw array
free(raw);

A convenient, simple and fast way to get rid of \0 is to copy the string without the last char (\0) with the help of strncpy instead of strcpy:

strncpy(newStrg,oldStrg,(strlen(oldStrg)-1));

Yes, this is a kind of inconsistency in the language.

The "=" in myarray = "abc"; is assignment (which won't work as the array is basically a kind of constant pointer), whereas in char myarray[4] = "abc"; it's an initialization of the array. There's no way for "late initialization".

You should just remember this rule.

(I just got this working, with my main issue being that I don't have a real internet hostname, so answering this question in case it helps someone)

You need to specify a hostname with HELO. Even so, you should get an error, so Postfix is probably not running.

Also, the => is not a command. The '.' on a single line without any text around it is what tells Postfix that the entry is complete. Here are the entries I used:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: [email protected]
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

You should get a response like:

250 2.0.0 Ok: queued as 6E414C4643A

The email will probably end up in a junk folder. If it is not showing up, then you probably need to setup the 'Postfix on hosts without a real Internet hostname'. Here is the breakdown on how I completed that step on my Ubuntu box:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
[email protected]             [email protected]
[email protected]             [email protected]
@localdomain.local                [email protected]
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

Happy Trails

Something going wrong is get_words() always returning one less than the actual word count, so eventually you attempt to:

char *newbuff[words]; /* Words is one less than the actual number,
so this is declared to be too small. */

newbuff[count2] = (char *)malloc(strlen(buffer))

count2, eventually, is always one more than the number of elements you've declared for newbuff[]. Why malloc() isn't returning a valid ptr, though, I don't know.

As already pointed out in other answers, memmove is more sophisticated than memcpy such that it accounts for memory overlaps. The result of memmove is defined as if the src was copied into a buffer and then buffer copied into dst. This does NOT mean that the actual implementation uses any buffer, but probably does some pointer arithmetic.

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Some feedback on the segment of code, though for the most part, it should work...

void main(int c,char **args)

• int main - the standard defines main as returning an int.
• c and args are typically named argc and argv, respectfully, but you are allowed to name them anything

...

{
DIR *dir;
struct dirent *dent;
char buffer[50];
strcpy(buffer,args[1]);

• You have a buffer overflow here: If args[1] is longer than 50 bytes, buffer will not be able to hold it, and you will write to memory that you shouldn't. There's no reason I can see to copy the buffer here, so you can sidestep these issues by just not using strcpy...

...

dir=opendir(buffer);   //this part

If this returning NULL, it can be for a few reasons:

• The directory didn't exist. (Did you type it right? Did it have a space in it, and you typed ./your_program my directory, which will fail, because it tries to opendir("my"))
• You lack permissions to the directory
• There's insufficient memory. (This is unlikely.)

I have faced the same issue related to Strings equality check, One of the comparing string has ASCII character code 128-255.

i.e., Non-breaking space - [Hex - A0] Space [Hex - 20]. To show Non-breaking space over HTML. I have used the following spacing entities. Their character and its bytes are like &emsp is very wide space[ ]{-30, -128, -125}, &ensp is somewhat wide space[ ]{-30, -128, -126}, &thinsp is narrow space[ ]{32} , Non HTML Space {}

String s1 = "My Sample Space Data", s2 = "My Sample Space Data";
System.out.format("S1: %s\n", java.util.Arrays.toString(s1.getBytes()));
System.out.format("S2: %s\n", java.util.Arrays.toString(s2.getBytes()));

Output in Bytes:

S1: [77, 121, 32, 83, 97, 109, 112, 108, 101, 32, 83, 112, 97, 99, 101, 32, 68, 97, 116, 97] S2: [77, 121, -30, -128, -125, 83, 97, 109, 112, 108, 101, -30, -128, -125, 83, 112, 97, 99, 101, -30, -128, -125, 68, 97, 116, 97]

Use below code for Different Spaces and their Byte-Codes: wiki for List_of_Unicode_characters

String spacing_entities = "very wide space,narrow space,regular space,invisible separator";
System.out.println("Space String :"+ spacing_entities);
byte[] byteArray = 
    // spacing_entities.getBytes( Charset.forName("UTF-8") );
    // Charset.forName("UTF-8").encode( s2 ).array();
    {-30, -128, -125, 44, -30, -128, -126, 44, 32, 44, -62, -96};
System.out.println("Bytes:"+ Arrays.toString( byteArray ) );
try {
    System.out.format("Bytes to String[%S] \n ", new String(byteArray, "UTF-8"));
} catch (UnsupportedEncodingException e) {
    e.printStackTrace();
}

• ? ASCII transliterations of Unicode string for Java. unidecode

  String initials = Unidecode.decode( s2 );
  

• ? using Guava: Google Core Libraries for Java.

  String replaceFrom = CharMatcher.WHITESPACE.replaceFrom( s2, " " );
  

  For URL encode for the space use Guava laibrary.

  String encodedString = UrlEscapers.urlFragmentEscaper().escape(inputString);
  

• ? To overcome this problem used String.replaceAll() with some RegularExpression.

  // \p{Z} or \p{Separator}: any kind of whitespace or invisible separator.
  s2 = s2.replaceAll("\\p{Zs}", " ");
  
  
  s2 = s2.replaceAll("[^\\p{ASCII}]", " ");
  s2 = s2.replaceAll(" ", " ");
  

• ? Using java.text.Normalizer.Form. This enum provides constants of the four Unicode normalization forms that are described in Unicode Standard Annex #15 — Unicode Normalization Forms and two methods to access them.

  

  s2 = Normalizer.normalize(s2, Normalizer.Form.NFKC);
  

Testing String and outputs on different approaches like ? Unidecode, Normalizer, StringUtils.

String strUni = "Thïs iš â funky Štring Æ,Ø,Ð,ß";

// This is a funky String AE,O,D,ss
String initials = Unidecode.decode( strUni );

// Following Produce this o/p: Th^i¨s^ i~s? a^ fu°n?k¸y^ S?t?r´i?n´g? Æ,Ø,Ð,ß
String temp = Normalizer.normalize(strUni, Normalizer.Form.NFD);
Pattern pattern = Pattern.compile("\\p{InCombiningDiacriticalMarks}+");
temp = pattern.matcher(temp).replaceAll("");

String input = org.apache.commons.lang3.StringUtils.stripAccents( strUni );

Using Unidecode is the best choice, My final Code shown below.

public static void main(String[] args) {
    String s1 = "My Sample Space Data", s2 = "My Sample Space Data";
    String initials = Unidecode.decode( s2 );
    if( s1.equals(s2)) { //[ , ] %A0 - %2C - %20 « http://www.ascii-code.com/
        System.out.println("Equal Unicode Strings");
    } else if( s1.equals( initials ) ) {
        System.out.println("Equal Non Unicode Strings");
    } else {
        System.out.println("Not Equal");
    }

}

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

I think you're x86-64 install does not have the i386 runtime linker. The ENOENT is probably due to the OS looking for something like /lib/ld.so.1 or similar. This is typically part of the 32-bit glibc runtime, and while I'm not directly familiar with Ubuntu, I would assume they have some sort of 32-bit compatibility package to install. Fortunately gzip only depends on the C library, so that's probably all you'll need to install.

In addition to the Wikipedia Cyclic redundancy check and Computation of CRC articles, I found a paper entitled Reversing CRC - Theory and Practice^* to be a good reference.

There are essentially three approaches for computing a CRC: an algebraic approach, a bit-oriented approach, and a table-driven approach. In Reversing CRC - Theory and Practice^*, each of these three algorithms/approaches is explained in theory accompanied in the APPENDIX by an implementation for the CRC32 in the C programming language.

Your string may contain non Latin1 characters, which leads to undefined data. It depends of what you mean by "it deosn't seem to work".

Observations:

• #include <cstring> should introduce std::strcpy().
• using namespace std; (as written in medico.h) introduces any identifiers from std:: into the global namespace.

Aside from using namespace std; being somewhat clumsy once the application grows larger (as it introduces one hell of a lot of identifiers into the global namespace), and that you should never use using in a header file (see below!), using namespace does not affect identifiers introduced after the statement.

(using namespace std is written in the header, which is included in medico.cpp, but #include <cstring> comes after that.)

My advice: Put the using namespace std; (if you insist on using it at all) into medico.cpp, after any includes, and use explicit std:: in medico.h.

strcmpi() is not a standard function at all; while being defined on Windows, you have to solve case-insensitive compares differently on Linux.

(On general terms, I would like to point to this answer with regards to "proper" string handling in C and C++ that takes Unicode into account, as every application should. Summary: The standard cannot handle these things correctly; do use ICU.)

warning: deprecated conversion from string constant to ‘char*’

A "string constant" is when you write a string literal (e.g. "Hello") in your code. Its type is const char[], i.e. array of constant characters (as you cannot change the characters). You can assign an array to a pointer, but assigning to char *, i.e. removing the const qualifier, generates the warning you are seeing.

OT clarification: using in a header file changes visibility of identifiers for anyone including that header, which is usually not what the user of your header file wants. For example, I could use std::string and a self-written ::string just perfectly in my code, unless I include your medico.h, because then the two classes will clash.

Don't use using in header files.

And even in implementation files, it can introduce lots of ambiguity. There is a case to be made to use explicit namespacing in implementation files as well.

In fact a string constant literal is neither a const char * nor a char* but a char[]. Its quite strange but written down in the c++ specifications; If you modify it the behavior is undefined because the compiler may store it in the code segment.

Here's some madness for you, I actually went and measured it. Bloody hell, imagine that. I think I got some meaningful results.

I used a dual core P4, running Windows, using mingw gcc 4.4, building with "gcc foo.c -o foo.exe -std=c99 -Wall -O2".

I tested method 1 and method 2 from the original post. Initially kept the malloc outside the benchmark loop. Method 1 was 48 times faster than method 2. Bizarrely, removing -O2 from the build command made the resulting exe 30% faster (haven't investigated why yet).

Then I added a malloc and free inside the loop. That slowed down method 1 by a factor of 4.4. Method 2 slowed down by a factor of 1.1.

So, malloc + strlen + free DO NOT dominate the profile enough to make avoiding sprintf worth while.

Here's the code I used (apart from the loops were implemented with < instead of != but that broke the HTML rendering of this post):

void a(char *first, char *second, char *both)
{
    for (int i = 0; i != 1000000 * 48; i++)
    {
        strcpy(both, first);
        strcat(both, " ");
        strcat(both, second);
    }
}

void b(char *first, char *second, char *both)
{
    for (int i = 0; i != 1000000 * 1; i++)
        sprintf(both, "%s %s", first, second);
}

int main(void)
{
    char* first= "First";
    char* second = "Second";
    char* both = (char*) malloc((strlen(first) + strlen(second) + 2) * sizeof(char));

    // Takes 3.7 sec with optimisations, 2.7 sec WITHOUT optimisations!
    a(first, second, both);

    // Takes 3.7 sec with or without optimisations
    //b(first, second, both);

    return 0;
}

the strncpy is a safer version of strcpy as a matter of fact you should never use strcpy because its potential buffer overflow vulnerability which makes you system vulnerable to all sort of attacks

In theory, malloc gets memory from the operating system for this application. However, since you may only want 4 bytes, and the OS needs to work in pages (often 4k), malloc does a little more than that. It takes a page, and puts it's own information in there so it can keep track of what you have allocated and freed from that page.

When you allocate 4 bytes, for instance, malloc gives you a pointer to 4 bytes. What you may not realize is that the memory 8-12 bytes before your 4 bytes is being used by malloc to make a chain of all the memory you have allocated. When you call free, it takes your pointer, backs up to where it's data is, and operates on that.

When you free memory, malloc takes that memory block off the chain... and may or may not return that memory to the operating system. If it does, than accessing that memory will probably fail, as the OS will take away your permissions to access that location. If malloc keeps the memory ( because it has other things allocated in that page, or for some optimization ), then the access will happen to work. It's still wrong, but it might work.

DISCLAIMER: What I described is a common implementation of malloc, but by no means the only possible one.

I met these warnings on mempcpy function. Man page says this function is a GNU extension and synopsis shows:

#define _GNU_SOURCE
#include <string.h>

When #define is added to my source before the #include, declarations for the GNU extensions are made visible and warnings disappear.

Extending adam-rosenfield's solution, i think the following will work for multithreaded single producer - single consumer scenario.

int cb_push_back(circular_buffer *cb, const void *item)
{
  void *new_head = (char *)cb->head + cb->sz;
  if (new_head == cb>buffer_end) {
      new_head = cb->buffer;
  }
  if (new_head == cb->tail) {
    return 1;
  }
  memcpy(cb->head, item, cb->sz);
  cb->head = new_head;
  return 0;
}

int cb_pop_front(circular_buffer *cb, void *item)
{
  void *new_tail = cb->tail + cb->sz;
  if (cb->head == cb->tail) {
    return 1;
  }
  memcpy(item, cb->tail, cb->sz);
  if (new_tail == cb->buffer_end) {
    new_tail = cb->buffer;
  }
  cb->tail = new_tail;
  return 0;
}

KISS. You will be doing all sorts of other switch/case things with your enums so why should printing be different? Forgetting a case in your print routine isn't a huge deal when you consider there are about 100 other places you can forget a case. Just compile -Wall, which will warn of non-exhaustive case matches. Don't use "default" because that will make the switch exhaustive and you wont get warnings. Instead, let the switch exit and deal with the default case like so...

const char *myenum_str(myenum e)
{
    switch(e) {
    case ONE: return "one";
    case TWO: return "two";
    }
    return "invalid";
}

resize2fs Command will not work for all file systems.

Please confirm the file system of your instance using below command.

Please follow the procedure to expand volume by following the steps mentioned in Amazon official document for different file systems.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html

Default file system in Centos is xfs, use the following command for xfs file system to increase partition size.

sudo xfs_growfs -d /

then "df -h" to check.

$url = 'http://graph.facebook.com/100000771470028/picture?type=large';
$rray=get_headers($url);
$hd = $rray[4];
echo(substr($hd,strpos($hd,'http')));

This will return the url that you asked, and the problem of changing the url by facebook doesn't matter because you are dynamically calling the url from the original url.

Could use Tortoise:

Below are a few extra steps on a fresh Mac that some people might need. This adds a little to @jnovack's excellent answer.

Update: A few other notes when setting this up:

Make sure your admin user has a password. A blank password won't work when trying to enable a root user.

System Preferences > Users and Groups > (select user) > Change password

Then to enable root, run dsenableroot in a terminal:

$ dsenableroot
username = mac_admin_user
user password:
root password:
verify root password:

dsenableroot:: ***Successfully enabled root user.

Type in the admin user's password, then the new enabled root password twice.

Next type:

sudo gcc

or

sudo make

It will respond with something like the following:

WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.

To proceed, enter your password, or type Ctrl-C to abort.

With Mavericks, it is a little different now.

When the tools were NOT found, this is what the command pkgutil command returned:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
No receipt for 'com.apple.pkg.CLTools_Executables' found at '/'.

To install the command line tools, this works nicely from the Terminal, with a nice gui and everything.

$ xcode-select --install

http://macops.ca/installing-command-line-tools-automatically-on-mavericks/

When they were found, this is what the pkgutil command returned:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 5.0.1.0.1.1382131676

install-time: 1384149984
groups: com.apple.FindSystemFiles.pkg-group com.apple.DevToolsBoth.pkg-group com.apple.DevToolsNonRelocatableShared.pkg-group 

This command returned the same before and after the install.

$ pkgutil --pkg-info=com.apple.pkg.DeveloperToolsCLI
No receipt for 'com.apple.pkg.DeveloperToolsCLI' found at '/'.

Also I had the component for the CLT selected and installed in xcode's downloads section before, but it seems like it didn't make it to the terminal...

Hope that helps.

This is because you have made conflicting changes to its master. And your repository server is not able to tell you that with these words, so it gives this error because it is not a matter of him deal with these conflicts for you, so he asks you to do it by itself. As ?

1- git pull This will merge your code from your repository to your code of your site master. So conflicts are shown.

2- treat these manualemente conflicts.

3-

git push origin master

And presto, your problem has been resolved.

You probably get the error because your video path may be wrong in a way. Be sure your path is completely correct.

But,if you want to store a bunch of them you could bit-shift them and store them all as one int, a little like unix file permissions/modes.

For mode 755 for instance, each digit refers to a different class of users: owner, group, public. Within each digit 4 is read, 2 is write, 1 is execute so 7 is all of them like binary 111. 5 is read and execute so 101. Make up your own encoding scheme.

I'm just writing something for storing TV schedule data from Schedules Direct and I have the binary or yes/no fields: stereo, hdtv, new, ei, close captioned, dolby, sap in Spanish, season premiere. So 7 bits, or an integer with a maximum of 127. One character really.

A C example from what I'm working on now. has() is a function that returns 1 if the 2nd string is in the first one. inp is the input string to this function. misc is an unsigned char initialized to 0.

if (has(inp,"sap='Spanish'") > 0)
  misc += 1;
if (has(inp,"stereo='true'") > 0)
  misc +=2;
if (has(inp,"ei='true'") > 0)
  misc +=4;
if (has(inp,"closeCaptioned='true'") > 0)
  misc += 8;
if (has(inp,"dolby=") > 0)
  misc += 16;
if (has(inp,"new='true'") > 0)
  misc += 32;
if (has(inp,"premier_finale='") > 0)
  misc += 64;
if (has(inp,"hdtv='true'") > 0)
  misc += 128;

So I'm storing 7 booleans in one integer with room for more.

According to wikipedia article on status codes. Nginx has a custom error code when http traffic is sent to https port(error code 497)

And according to nginx docs on error_page, you can define a URI that will be shown for a specific error.
Thus we can create a uri that clients will be sent to when error code 497 is raised.

nginx.conf

#lets assume your IP address is 89.89.89.89 and also 
#that you want nginx to listen on port 7000 and your app is running on port 3000

server {
    listen 7000 ssl;
 
    ssl_certificate /path/to/ssl_certificate.cer;
    ssl_certificate_key /path/to/ssl_certificate_key.key;
    ssl_client_certificate /path/to/ssl_client_certificate.cer;

    error_page 497 301 =307 https://89.89.89.89:7000$request_uri;

    location / {
        proxy_pass http://89.89.89.89:3000/;

        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Protocol $scheme;
    }
}

However if a client makes a request via any other method except a GET, that request will be turned into a GET. Thus to preserve the request method that the client came in via; we use error processing redirects as shown in nginx docs on error_page

And thats why we use the 301 =307 redirect.

Using the nginx.conf file shown here, we are able to have http and https listen in on the same port

You need to turn on Show All Files option on solution pane toolbar and include this file manually.

The docker cli credential scheme is unsurprisingly uncomplicated, just take a look:

cat ~/.docker/config.json

{
  "auths": {
    "dockerregistry.myregistry.com": {},
    "https://index.docker.io/v1/": {}

This exists on Windows (use Get-Content ~\.docker\config.json) and you can also poke around the credential tool which also lists the username ... and I think you can even retrieve the password

. "C:\Program Files\Docker\Docker\resources\bin\docker-credential-wincred.exe" list

{"https://index.docker.io/v1/":"kcd"}

Try with below logic

driver.get("http://www.labmultis.info/jpecka.portal-exdrazby/index.php?c1=2&a=s&aa=&ta=1");

List<WebElement> allElements=driver.findElements(By.cssSelector(".list.list-categories li"));

for(WebElement ele :allElements) {
    System.out.println("Name + Number===>"+ele.getText());
    String s=ele.getText();
    s=s.substring(s.indexOf("(")+1, s.indexOf(")"));
    System.out.println("Number==>"+s);
}

====Output======

rsync is a program that behaves in much the same way that rcp does, but has many more options and uses the rsync remote-update protocol to greatly speed up file transfers when the destination file is being updated.

The rsync remote-update protocol allows rsync to transfer just the differences between two sets of files across the network connection, using an efficient checksum-search algorithm described in the technical report that accompanies this package.

Copying folder from one location to another

   #!/usr/bin/expect -f   
   spawn rsync -a -e ssh [email protected]:/cool/cool1/* /tmp/cool/   
   expect "password:"   
   send "cool\r"   
   expect "*\r"   
   expect "\r"  

sudo snap install postman

This single command worked for me.

You could use typecasting:

Scanner sc= new Scanner(System.in);
char a=(char) sc.next();

This way you will take input in String due to the function 'next()' but then it will be converted into character due to the 'char' mentioned in the brackets.

This method of conversion of data type by mentioning the destination data type in brackets is called typecating. It works for me, I hope it works for u :)

Basically like this,

<?php
$link = ""; // Link goes here!
print "<a href="'.$link.'">Link</a>";
?>

open file, save as .csv and then apply

for any other format also, just change the sep tag

The current cookie specification is RFC 6265, which replaces RFC 2109 and RFC 2965 (both RFCs are now marked as "Historic") and formalizes the syntax for real-world usages of cookies. It clearly states:

1. Introduction

...

For historical reasons, cookies contain a number of security and privacy infelicities. For example, a server can indicate that a given cookie is intended for "secure" connections, but the Secure attribute does not provide integrity in the presence of an active network attacker. Similarly, cookies for a given host are shared across all the ports on that host, even though the usual "same-origin policy" used by web browsers isolates content retrieved via different ports.

And also:

8.5. Weak Confidentiality

Cookies do not provide isolation by port. If a cookie is readable by a service running on one port, the cookie is also readable by a service running on another port of the same server. If a cookie is writable by a service on one port, the cookie is also writable by a service running on another port of the same server. For this reason, servers SHOULD NOT both run mutually distrusting services on different ports of the same host and use cookies to store security sensitive information.

No reason but indifference, I'd guess.

Such query strings are usually generated by a graphical query tool. The user joins a few tables, adds a filter, a sort order, and tests the results. Since the user may want to save the query as a view, the tool adds a TOP 100 PERCENT. In this case, though, the user copies the SQL into his code, parameterized the WHERE clause, and hides everything in a data access layer. Out of mind, out of sight.

You can iterate through the key-value pair and write it into file

pair = {'name': name,'location': location}
with open('F:\\twitter.json', 'a') as f:
     f.writelines('{}:{}'.format(k,v) for k, v in pair.items())
     f.write('\n')

You could just use a HashSet<String> to maintain a collection of unique objects. If the Integer values in your map are important, then you can instead use the containsKey method of maps to test whether your key is already in the map.

Follow the below steps to sign the application in the android studio:-

1. First Go to Build->Generate Signed APK

   

2. Then Once you click on the Generate Signed APK then there is info dialog message appear.

   

3. Click on the Create New button if you don't have any keystore file. If you have click on the Choose Existing.

   

4. Once you click on the Create New button then now dialog box appear where you need to enter the keystore file info, other signing authority details.

   

5. Once you fill complete details then click on the Ok button then it redirect to this dialog.

   

6. Click on the Next button then check mark on the Run ProGuard and click on the finish. It generate the signed APK.

   

   

when you return some thing, the code exits out of the loop with what ever you are returning.so, in your code, in the first iteration, name is "one". so, as soon as it reaches return new Text(name), code exits the loop with return new Text("one"). so, try to print it or use asynchronous returns.

In the beginning, I did not get why the question has a bounty (I thought that the question has a nice answer and there is nothing to add), but then I noticed that the answer which was accepted and upvoted 15 times was actually wrong!

Yes, you have to use $unset operator, but this unset is going to remove the words key which does not exist for a document for a collection. So basically it will do nothing.

So you need to tell Mongo to look in the document tags and then in the words using dot notation. So the correct query is.

db.example.update(
  {},
  { $unset: {'tags.words':1}},
  false, true
)

Just for the sake of completion, I will refer to another way of doing it, which is much worse, but this way you can change the field with any custom code (even based on another field from this document).

widget['bg'] = '#000000'

or

widget['background'] = '#000000'

would also work as hex-valued colors are also accepted.

Here is my contribution to the debate ... This returns a single array with the data separated and the headers listed. This works on the basis that CURL will return a headers chunk [ blank line ] data

curl_setopt($ch, CURLOPT_HEADER, 1); // we need this to get headers back
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, true);

// $output contains the output string
$output = curl_exec($ch);

$lines = explode("\n",$output);

$out = array();
$headers = true;

foreach ($lines as $l){
    $l = trim($l);

    if ($headers && !empty($l)){
        if (strpos($l,'HTTP') !== false){
            $p = explode(' ',$l);
            $out['Headers']['Status'] = trim($p[1]);
        } else {
            $p = explode(':',$l);
            $out['Headers'][$p[0]] = trim($p[1]);
        }
    } elseif (!empty($l)) {
        $out['Data'] = $l;
    }

    if (empty($l)){
        $headers = false;

I found, that chrome and chromedriver versions support policy has changed recently.

There is general guide to select version of crhomedriver for specific chrome version: https://sites.google.com/a/chromium.org/chromedriver/downloads/version-selection

Here is excerpt:

• First, find out which version of Chrome you are using. Let's say you have Chrome 72.0.3626.81.
• Take the Chrome version number, remove the last part, and append the result to URL "https://chromedriver.storage.googleapis.com/LATEST_RELEASE_". For example, with Chrome version 72.0.3626.81, you'd get a URL "https://chromedriver.storage.googleapis.com/LATEST_RELEASE_72.0.3626".
• Use the URL created in the last step to retrieve a small file containing the version of ChromeDriver to use. For example, the above URL will get your a file containing "72.0.3626.69". (The actual number may change in the future, of course.)
• Use the version number retrieved from the previous step to construct the URL to download ChromeDriver. With version 72.0.3626.69, the URL would be "https://chromedriver.storage.googleapis.com/index.html?path=72.0.3626.69/".
• After the initial download, it is recommended that you occasionally go through the above process again to see if there are any bug fix releases.

Note, that this version selection algorithm can be easily automated. For example, simple powershell script in another answer has automated chromedriver updating on windows platform.

In this specific example, where the DataFrame is only one column, you can write this elegantly as:

df['desired_output'] = df.le(2.5)

le tests whether elements are less than or equal 2.5, similarly lt for less than, gt and ge.

I'd use iloc, which takes a row/column slice, both based on integer position and following normal python syntax. If you want every 5th row:

df.iloc[::5, :]

I was getting this error in PyroCMS.

You can improve the error message in the Loader.php file that is in the code of the library.

Open the Loader.php file and find any calls to show_error. I replaced mine with the following:

show_error(sprintf("Unable to load the requested file: \"%s\" with instance title of \"%s\"", $_ci_file, $_ci_data['_ci_vars']['options']['instance_title']));

I was then able to see which file was causing the issues for me.

It seems that the most accurate (and seamless) method of adding the padding for iPhone X/8 using env()...

padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);

Here's a link describing this:

There is no built-in functionality in VBS for that, however, you can use the FileSystemObject FileExists function for that :

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")

If (fso.FileExists("C:\Program Files\conf")) Then
  WScript.Echo("File exists!")
  WScript.Quit()
Else
  WScript.Echo("File does not exist!")
End If

WScript.Quit()

There is no way to automatically set CMAKE_PREFIX_PATH in a way you want. I see following ways to solve this problem:

1. Put all libraries files in the same dir. That is, include/ would contain headers for all libs, lib/ - binaries, etc. FYI, this is common layout for most UNIX-like systems.

2. Set global environment variable CMAKE_PREFIX_PATH to D:/develop/cmake/libs/libA;D:/develop/cmake/libs/libB;.... When you run CMake, it would aautomatically pick up this env var and populate it's own CMAKE_PREFIX_PATH.

3. Write a wrapper .bat script, which would call cmake command with -D CMAKE_PREFIX_PATH=... argument.

It is a general vision. Details are depended on real language realisation

lock - thread synchronization tool. When thread get a lock it becomes a single thread which is able to execute a block of code. All others thread are blocked. Only thread which owns by lock can unlock it

mutex - mutual exclusion lock. It is a kind of lock. On some languages it is inter-process mechanism, on some languages it is a synonym of lock. For example Java uses lock in synchronised and java.util.concurrent.locks.Lock

semaphore - allows a number of threads to access a shared resource. You can find that mutex also can be implemented by semaphore. It is a standalone object which manage an access to shared resource. You can find that any thread can signal and unblock. Also it is used for signalling

[iOS lock, mutex, semaphore]

This worked for me: run

sudo lsof -i :<port_number>

after that it will display the PID which is currently attached to the process.

After that run sudo kill -9 <PID>

if that doesn't work, try the solution offered by user8376606 it would definitely work!

Even though the ID selector is the simplest, you can also use the name selector as below:

$('[name='submitted[first_name]']').removeAttr('required');

For more see: https://api.jquery.com/attribute-equals-selector/

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

I am also looking for similar feature "list all resources" in AWS but could not find anything good enough.

"Resource Groups" does not help because it only list resources which have been tagged and user have to specify the tag. If you miss to tag a resource, that won't appear in "Resource Groups" .

UI of "Create a resource group"

A more suitable feature is "Resource Groups"->"Tag Editor" as already mentioned in the previous post. Select region(s) and resource type(s) to see listing of resources in Tag editor. This serves the purpose but not very user-friendly because I have to enter region and resource type every time I want to use it. I am still looking for easy to use UI.

UI of "Find resource" under "Tag Editor"

private void button1_Click(object sender, EventArgs e)
{
        Form2 frm2 = new Form2(textBox1.Text);
        frm2.Show();    
}

 public Form2(string qs)
    {
        InitializeComponent();
        textBox1.Text = qs;

    }

Here is another solution to the old question. There have been many excellent answers to this question over the years and my attempt borrows heavily from them.

I used Andrey Lebedenko's solution as a starting point because its output was already very close to my requirements.

Features:

• following common practice I have moved the foreign key constraints outside the table definition. They are now included as ALTER TABLE statements at the bottom. The reason is that a foreign key can also link to a column of the same table. In that fringe case the constraint can only be created after the table creation is completed. The create table statement would throw an error otherwise.
• The layout and indenting looks nicer now (at least to my eye)
• Drop command (commented out) in the header of the definition
• The solution is offered here as a plpgsql function. The algorithm does however not use any procedural language. The function just wraps one single query that can be used in a pure sql context as well.
• removed redundant subqueries
• Identifiers are now quoted if they are identical to reserved postgresql language elements
• replaced the string concatenation operator || with the appropriate string functions to improve performance, security and readability of the code. Note: the || operator produces NULL if one of the combined strings is NULL. It should only be used when that is the desired behaviour. (check out the usage in the code below for an example)

From the definition of height:

Applies to: all elements but non-replaced inline elements, table columns, and column groups

An a element is, by default an inline element (and it is non-replaced).

You need to change the display (directly with the display property or indirectly, e.g. with float).

Try this

Months.values()[index]

If I understand you correctly, you want to do something like this:

In such case, it should be just enough to use:

<item name="android:colorButtonNormal">#2196f3</item>

Or for API less than 21:

<item name="colorButtonNormal">#2196f3</item>

In addition to Using Material Theme Tutorial.

Animated variant is here.

Make sure you have your default page named as index.aspx and not something like main.aspx or home.aspx . And also see to it that all your properties in your class matches exactly with that of your table in the database. Remove any properties that is not in sync with the database. That solved my problem!! :)

You can use the for..in TypeScript operator to access the index when dealing with collections.

var test = [7,8,9];
for (var i in test) {
   console.log(i + ': ' + test[i]);
} 

Output:

 0: 7
 1: 8
 2: 9

Please check https://www.sqlite.org/lang_altertable.html#otheralter

The only schema altering commands directly supported by SQLite are the "rename table" and "add column" commands shown above. However, applications can make other arbitrary changes to the format of a table using a simple sequence of operations. The steps to make arbitrary changes to the schema design of some table X are as follows:

1. If foreign key constraints are enabled, disable them using PRAGMA foreign_keys=OFF.
2. Start a transaction.
3. Remember the format of all indexes and triggers associated with table X. This information will be needed in step 8 below. One way to do this is to run a query like the following: SELECT type, sql FROM sqlite_master WHERE tbl_name='X'.
4. Use CREATE TABLE to construct a new table "new_X" that is in the desired revised format of table X. Make sure that the name "new_X" does not collide with any existing table name, of course.
5. Transfer content from X into new_X using a statement like: INSERT INTO new_X SELECT ... FROM X.
6. Drop the old table X: DROP TABLE X.
7. Change the name of new_X to X using: ALTER TABLE new_X RENAME TO X.
8. Use CREATE INDEX and CREATE TRIGGER to reconstruct indexes and triggers associated with table X. Perhaps use the old format of the triggers and indexes saved from step 3 above as a guide, making changes as appropriate for the alteration.
9. If any views refer to table X in a way that is affected by the schema change, then drop those views using DROP VIEW and recreate them with whatever changes are necessary to accommodate the schema change using CREATE VIEW.
10. If foreign key constraints were originally enabled then run PRAGMA foreign_key_check to verify that the schema change did not break any foreign key constraints.
11. Commit the transaction started in step 2.
12. If foreign keys constraints were originally enabled, reenable them now.

The procedure above is completely general and will work even if the schema change causes the information stored in the table to change. So the full procedure above is appropriate for dropping a column, changing the order of columns, adding or removing a UNIQUE constraint or PRIMARY KEY, adding CHECK or FOREIGN KEY or NOT NULL constraints, or changing the datatype for a column, for example.

If you want to use the object of ith term and input it to another component in each iteration then:

<table class="table table-striped table-hover">
  <tr>
    <th> Blogs </th>
  </tr>
  <tr *ngFor="let blogEl of blogs">
    <app-blog-item [blog]="blogEl"> </app-blog-item>
  </tr>
</table>

Another option would be to use a keyed data.table:

library(data.table)
setDT(dt, key = 'fct')[J(vc)]  # or: setDT(dt, key = 'fct')[.(vc)]

which results in:

   fct X
1:   a 2
2:   a 7
3:   a 1
4:   c 3
5:   c 5
6:   c 9
7:   c 2
8:   c 4

What this does:

• setDT(dt, key = 'fct') transforms the data.frame to a data.table (which is an enhanced form of a data.frame) with the fct column set as key.
• Next you can just subset with the vc vector with [J(vc)].

NOTE: when the key is a factor/character variable, you can also use setDT(dt, key = 'fct')[vc] but that won't work when vc is a numeric vector. When vc is a numeric vector and is not wrapped in J() or .(), vc will work as a rowindex.

A more detailed explanation of the concept of keys and subsetting can be found in the vignette Keys and fast binary search based subset.

An alternative as suggested by @Frank in the comments:

setDT(dt)[J(vc), on=.(fct)]

When vc contains values that are not present in dt, you'll need to add nomatch = 0:

setDT(dt, key = 'fct')[J(vc), nomatch = 0]

or:

setDT(dt)[J(vc), on=.(fct), nomatch = 0]

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

Great solution but for my Windows I need make a modifications. Below the modify code

function Zip($source, $destination){

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
    return false;
}

$source = str_replace('\\', '/', realpath($source));

if (is_dir($source) === true)

I also wanted to create OPEN SSL for Windows 10. An easy way of getting it done without running into a risk of installing unknown software from 3rd party websites and risking entries of viruses, is by using the openssl.exe that comes inside your Git for Windows installation. In my case, I found the open SSL in the following location of Git for Windows Installation.

C:\Program Files\Git\usr\bin\openssl.exe

If you also want instructions on how to use OPENSSL to generate and use Certificates. Here is a write-up on my blog. The step by step instructions first explains how to use Microsoft Windows Default Tool and also OPEN SSL and explains the difference between them.

The aim of using StringBuilder, i.e reducing memory. Is it achieved?

No, not at all. That code is not using StringBuilder correctly. (I think you've misquoted it, though; surely there aren't quotes around id2 and table?)

Note that the aim (usually) is to reduce memory churn rather than total memory used, to make life a bit easier on the garbage collector.

Will that take memory equal to using String like below?

No, it'll cause more memory churn than just the straight concat you quoted. (Until/unless the JVM optimizer sees that the explicit StringBuilder in the code is unnecessary and optimizes it out, if it can.)

If the author of that code wants to use StringBuilder (there are arguments for, but also against; see note at the end of this answer), better to do it properly (here I'm assuming there aren't actually quotes around id2 and table):

StringBuilder sb = new StringBuilder(some_appropriate_size);
sb.append("select id1, ");
sb.append(id2);
sb.append(" from ");
sb.append(table);
return sb.toString();

Note that I've listed some_appropriate_size in the StringBuilder constructor, so that it starts out with enough capacity for the full content we're going to append. The default size used if you don't specify one is 16 characters, which is usually too small and results in the StringBuilder having to do reallocations to make itself bigger (IIRC, in the Sun/Oracle JDK, it doubles itself [or more, if it knows it needs more to satisfy a specific append] each time it runs out of room).

You may have heard that string concatenation will use a StringBuilder under the covers if compiled with the Sun/Oracle compiler. This is true, it will use one StringBuilder for the overall expression. But it will use the default constructor, which means in the majority of cases, it will have to do a reallocation. It's easier to read, though. Note that this is not true of a series of concatenations. So for instance, this uses one StringBuilder:

return "prefix " + variable1 + " middle " + variable2 + " end";

It roughly translates to:

StringBuilder tmp = new StringBuilder(); // Using default 16 character size
tmp.append("prefix ");
tmp.append(variable1);
tmp.append(" middle ");
tmp.append(variable2);
tmp.append(" end");
return tmp.toString();

So that's okay, although the default constructor and subsequent reallocation(s) isn't ideal, the odds are it's good enough — and the concatenation is a lot more readable.

But that's only for a single expression. Multiple StringBuilders are used for this:

String s;
s = "prefix ";
s += variable1;
s += " middle ";
s += variable2;
s += " end";
return s;

That ends up becoming something like this:

String s;
StringBuilder tmp;
s = "prefix ";
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable1);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" middle ");
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(variable2);
s = tmp.toString();
tmp = new StringBuilder();
tmp.append(s);
tmp.append(" end");
s = tmp.toString();
return s;

...which is pretty ugly.

It's important to remember, though, that in all but a very few cases it doesn't matter and going with readability (which enhances maintainability) is preferred barring a specific performance issue.

An enum is like a Singleton. The JVM creates the instance.

If you would create it by yourself with classes it could be look like that

public static class MyEnum {

    final public static MyEnum ONE;
    final public static MyEnum TWO;

    static {
        ONE = new MyEnum("1");
        TWO = new MyEnum("2");
    }

    final String enumValue;

    private MyEnum(String value){
        enumValue = value;    
    }

    @Override
    public String toString(){
        return enumValue;
    }


}

And could be used like that:

public class HelloWorld{

   public static class MyEnum {

       final public static MyEnum ONE;
       final public static MyEnum TWO;

       static {
          ONE = new MyEnum("1");
          TWO = new MyEnum("2");
       }

       final String enumValue;

       private MyEnum(String value){
           enumValue = value;    
       }

       @Override
       public String toString(){
           return enumValue;
       }


   }

    public static void main(String []args){

       System.out.println(MyEnum.ONE);
       System.out.println(MyEnum.TWO);

       System.out.println(MyEnum.ONE == MyEnum.ONE);

       System.out.println("Hello World");
    }
}

With Underscore

Underscore provides a function _.mapObject to map the values and preserve the keys.

_.mapObject({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

DEMO

With Lodash

Lodash provides a function _.mapValues to map the values and preserve the keys.

_.mapValues({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

Good luck!

In a function call the single star turns a list into seperate arguments (e.g. zip(*x) is the same as zip(x1,x2,x3) if x=[x1,x2,x3]) and the double star turns a dictionary into seperate keyword arguments (e.g. f(**k) is the same as f(x=my_x, y=my_y) if k = {'x':my_x, 'y':my_y}.

In a function definition it's the other way around: the single star turns an arbitrary number of arguments into a list, and the double start turns an arbitrary number of keyword arguments into a dictionary. E.g. def foo(*x) means "foo takes an arbitrary number of arguments and they will be accessible through the list x (i.e. if the user calls foo(1,2,3), x will be [1,2,3])" and def bar(**k) means "bar takes an arbitrary number of keyword arguments and they will be accessible through the dictionary k (i.e. if the user calls bar(x=42, y=23), k will be {'x': 42, 'y': 23})".

This is a late contribution, but there is a valid case for casting json_decode with (array).
Consider the following:

$jsondata = '';
$arr = json_decode($jsondata, true);
foreach ($arr as $k=>$v){
    echo $v; // etc.
}

If $jsondata is ever returned as an empty string (as in my experience it often is), json_decode will return NULL, resulting in the error Warning: Invalid argument supplied for foreach() on line 3. You could add a line of if/then code or a ternary operator, but IMO it's cleaner to simply change line 2 to ...

$arr = (array) json_decode($jsondata,true);

... unless you are json_decodeing millions of large arrays at once, in which case as @TCB13 points out, performance could be negatively effected.

In my case there was a formatting issue earlier on, so the error was a consequence of something else. My server was rendering the lat/lon values with commas instead of periods, because of different regional settings.

You better try with AsyncTask

Sample code -

private class YourAsyncTask extends AsyncTask<Void, Void, Void> {
    private ProgressDialog dialog;

    public YourAsyncTask(MyMainActivity activity) {
        dialog = new ProgressDialog(activity);
    }

    @Override
    protected void onPreExecute() {
        dialog.setMessage("Doing something, please wait.");
        dialog.show();
    }
    @Override
    protected Void doInBackground(Void... args) {
        // do background work here
        return null;
    }
    @Override
    protected void onPostExecute(Void result) {
         // do UI work here
        if (dialog.isShowing()) {
            dialog.dismiss();
        }
    }
}

Use the above code in your Login Button Activity. And, do the stuff in doInBackground and onPostExecute

Update:

ProgressDialog is integrated with AsyncTask as you said your task takes time for processing.

Update:

ProgressDialog class was deprecated as of API 26

I want just emphasize that RecyclerView is a part of the compatibility package. It means that instead of using the feature and code from OS, every application carries own RecyclerView implementation. Potentially, a feature similar to RecyclerView can be a part of a future OS and using it from there can be beneficial. For example Harmony OS will be out soon.The compatibility package license can be changed in the future and it can be an implication. Summery of disadvantages:

1. licensing
2. a bigger foot print especially as a part of many apps
3. losing in efficiency if some feature coming from OS can be there

But on a good note, an implementation of some functionality, as swiping items, is coming from RecyclerView.

All said above has to be taken in a consideration.

I faced this issue with wamp on windows 7. Adding following code to httpd-vhosts.conf solved the issue for me.

In my specific case I tried to create a React Native app using the react-native init installation process, when I encountered the discussed problem.

FAILURE: Build failed with an exception.

* What went wrong:

A problem occurred configuring project ':app'.
> SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at 'C:\Users\***\android\local.properties'.

I add this, because when developing an android app using react native, the 'root directory' to which so many answers refer, is actually the root of the android folder (and not the project's root folder, where App.js resides). This is also made clear by the directory marked in the error message.

To solve it, just add a local.properties file to the android folder, and type:

sdk.dir=C:/Users/{user name}/AppData/Local/Android/Sdk

Be sure to add the local disk's reference ('C:/'), because it did not work otherwise in my case.

If You want to have a reference to this variable across the whole project, create somewhere d.ts file, e.g. globals.d.ts. Fill it with your global variables declarations, e.g.:

declare const BootBox: 'boot' | 'box';

Now you can reference it anywhere across the project, just like that:

const bootbox = BootBox;

Here's an example.

The following sample looks recursively for your search string in the *.xml and *.js files located somewhere inside the folders path1, path2 and path3.

grep -r --include=*.xml --include=*.js "your search string" path1 path2 path3

So you can search in a subset of the files for many directories, just providing the paths at the end.

import package
import module

With import, the token must be a module (a file containing Python commands) or a package (a folder in the sys.path containing a file __init__.py.)

When there are subpackages:

import package1.package2.package
import package1.package2.module

the requirements for folder (package) or file (module) are the same, but the folder or file must be inside package2 which must be inside package1, and both package1 and package2 must contain __init__.py files. https://docs.python.org/2/tutorial/modules.html

With the from style of import:

from package1.package2 import package
from package1.package2 import module

the package or module enters the namespace of the file containing the import statement as module (or package) instead of package1.package2.module. You can always bind to a more convenient name:

a = big_package_name.subpackage.even_longer_subpackage_name.function

Only the from style of import permits you to name a particular function or variable:

from package3.module import some_function

is allowed, but

import package3.module.some_function 

is not allowed.

You need to edit your ~/.ssh/config file. Add something like the following:

Microsoft .NET framework 3.5 can be installed on windows 10 without having installation media. The file you need is called microsoft-windows-netfx3-ondemand-package.cab. Just google it and you will get the download links. After downloading it, copy that file to C:\dotnet35 and run the following command.

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess

Tested and worked in Windows 10 without any issue.

>>> class Test:
...     def __repr__(self):
...         return "Test()"
...     def __str__(self):
...         return "member of Test"
... 
>>> t = Test()
>>> t
Test()
>>> print(t)
member of Test

The __str__ method is what happens when you print it, and the __repr__ method is what happens when you use the repr() function (or when you look at it with the interactive prompt). If this isn't the most Pythonic method, I apologize, because I'm still learning too - but it works.

If no __str__ method is given, Python will print the result of __repr__ instead. If you define __str__ but not __repr__, Python will use what you see above as the __repr__, but still use __str__ for printing.

May be easier using a java.util.HashSet. For example:

  List <String> list = new ArrayList<String>(); 
  list.add("behold");
  list.add("bend");
  list.add("bet");

  //Load the list into a hashSet
  Set<String> set = new HashSet<String>(list);
  if (set.contains("bend"))
  {
    System.out.println("String found!");
  }

I would advise against changing the default behaviour of a key. I do as much as possible without touching a mouse, so if you make my tab key not move to the next field on a form I will be very aggravated.

A shortcut key could be useful however, especially with large code blocks and nesting. Shift-TAB is a bad option because that normally takes me to the previous field on a form. Maybe a new button on the WMD editor to insert a code-TAB, with a shortcut key, would be possible?

After a lot of fiddling I found a better answer at sqlite docs for listing the metadata for the table, even attached databases.

Node.js is an open source command line tool built for the server side JavaScript code.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

The basic philosophy of node.js is:

Non-blocking I/O - every I/O call must take a callback, whether it is to retrieve information from disk, network or another process. Built-in support for the most important protocols (HTTP, DNS, TLS) Low-level. Do not remove functionality present at the POSIX layer. For example, support half-closed TCP connections. Stream everything; never force the buffering of data.

Apart from the similarities i.e. Task.Run() being a shorthand for Task.Factory.StartNew(), there is a minute difference between their behaviour in case of sync and async delegates.

Suppose there are following two methods:

public async Task<int> GetIntAsync()
{
    return Task.FromResult(1);
}

public int GetInt()
{
    return 1;
}

Now consider the following code.

var sync1 = Task.Run(() => GetInt());
var sync2 = Task.Factory.StartNew(() => GetInt());

Here both sync1 and sync2 are of type Task<int>

However, difference comes in case of async methods.

var async1 = Task.Run(() => GetIntAsync());
var async2 = Task.Factory.StartNew(() => GetIntAsync());

In this scenario, async1 is of type Task<int>, however async2 is of type Task<Task<int>>

You should check out heroku_san, it solves this problem quite nicely.

For example, you could:

git checkout BRANCH
rake qa deploy

It also makes it easy to spin up new Heroku instances to deploy a topic branch to new servers:

git checkout BRANCH
# edit config/heroku.yml with new app instance and shortname
rake shortname heroku:create deploy # auto creates deploys and migrates

And of course you can make simpler rake tasks if you do something frequently.

empty() used to work for this, but the behavior of empty() has changed several times. As always, the php docs are always the best source for exact behavior and the comments on those pages usually provide a good history of the changes over time. If you want to check for a lack of object properties, a very defensive method at the moment is:

if (is_object($theObject) && (count(get_object_vars($theObject)) > 0)) {

Also a little note: If you want to reduce the compilation-time, you can add the flag

-j2

to run two parallel builds at the same time. This might reduce it to viewing one movie ;)

After using hg update -r REV it wasn't clear in the answer about how to commit that change so that you can then push.

If you just try to commit after the update, Mercurial doesn't think there are any changes.

I had to first make a change to any file (say in a README) so Mercurial recognized that I made a new change, then I could commit that.

This then created two heads as mentioned.

To get rid of the other head before pushing, I then followed the No-Op Merges step to remedy that situation.

I was then able to push.

By dragging and dropping the dll onto 'regasm' you can register it. You can open two 'Window Explorer' windows. One will contain the dll you wish to register. The 2nd window will be the location of the 'regasm' application. Scroll down in both windows so that you have a view of both the dll and 'regasm'. It helps to reduce the size of the two windows so they are side-by-side. Be sure to drag the dll over the 'regasm' that is labeled 'application'. There are several 'regasm' files but you only want the application.

public List<int> GetPositions(string source, string searchString)
{
    List<int> ret = new List<int>();
    int len = searchString.Length;
    int start = -len;
    while (true)
    {
        start = source.IndexOf(searchString, start + len);
        if (start == -1)
        {
            break;
        }
        else
        {
            ret.Add(start);
        }
    }
    return ret;
}

Call it like this:

List<int> list = GetPositions("bob is a chowder head bob bob sldfjl", "bob");
// list will contain 0, 22, 26

Works for me. You probably want to multiplz it with 1000, since what you get are the seconds from 1970 and you have to pass the milliseconds from jan 1 1970

std::max_element

can be used.

Continuing from this answer: https://stackoverflow.com/a/15285514/1865860, I forked the nice github repo from @daniel-smith and made some improvements:

• improved example Activity
• improved layouts
• fixed setItems method
• added dividers into items_list
• dismiss dialogs on click
• support for disabled items in setItems methods
• listItem touch feedback
• scrollable dialog message

My issue was caused by missing bindings in IIS, in the left tree view "Connections", under Sites, Right click on your site > edit bindings > add > https

Choose 'IIS Express Development Certificate' and set port to 443 Then I added another binding to the webconfig:

<endpoint address="wsHttps" binding="wsHttpBinding" bindingConfiguration="DefaultWsHttpBinding" name="Your.bindingname" contract="Your.contract" />

Also added to serviceBehaviours: <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true" />

And eventually it worked, none of the solutions I checked on stackoverflow for this error was applicable to my specific scenario, so including here in case it helps others

I can spot a few different problems with this. However, in the interest of time, try this chunk of code instead:

Check if you do not have declared the method getAll() in the model. That causes the controller to think that you are calling a non-static method.

There are known issues with IE and Opera not removing session cookies when setting the expire date to the past (which is what the jQuery cookie plugin does)

This works fine in Safari and Mozilla/FireFox.

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

I wanted a more permanent and quicker way. Because I tend to forget to add extra lines before writing my actual Update/Insert queries.

I did it by checking SET IMPLICIT_TRANSACTIONS check-box from Options. To navigate to Options Select Tools>Options>Query Execution>SQL Server>ANSI in your Microsoft SQL Server Management Studio.

Just make sure to execute commit or rollback after you are done executing your queries. Otherwise, the table you would have run the query will be locked for others.

Do you need the object itself or do you just need to know if there is an object that satisfies. If the former then yes: use find:

found_object = my_array.find { |e| e.satisfies_condition? }

otherwise you can use any?

found_it = my_array.any?  { |e| e.satisfies_condition? }

The latter will bail with "true" when it finds one that satisfies the condition. The former will do the same, but return the object.

You must make your foreign key nullable:

public class User
{
    public int Id { get; set; }
    public int? CountryId { get; set; }
    public virtual Country Country { get; set; }
}

I like

 Get-WmiObject Win32_computersystem | format-custom *

That seems to expand everything.

There's also a show-object command in the PowerShellCookbook module that does it in a GUI. Jeffrey Snover, the PowerShell creator, uses it in his unplugged videos (recommended).

Although most often I use

Get-WmiObject Win32_computersystem | fl *

It avoids the .format.ps1xml file that defines a table or list view for the object type, if there are any. The format file may even define column headers that don't match any property names.

In the Storyboard, select the UITableView, and modify the property Style from Plain to Grouped.

You can use attachEvent(ie8) and addEventListener instead

addEvent(window, 'load', function(){ some_methods_1() });
addEvent(window, 'load', function(){ some_methods_2() });

function addEvent(element, eventName, fn) {
    if (element.addEventListener)
        element.addEventListener(eventName, fn, false);
    else if (element.attachEvent)
        element.attachEvent('on' + eventName, fn);
}

I use similar system as pix0r and I think that makes the code quite readable. Sometimes I would actually go as far as separating the line breaks in double quotes and use single quotes for the rest of the string. That way they stand out from the rest of the text and variables also stand out better if you use concatenation rather than inject them inside double quoted string. So I might do something like this with your original example:

$text = 'Hello ' . $vars->name . ','
      . "\r\n\r\n"
      . 'The second line starts two lines below.'
      . "\r\n\r\n"
      . 'I also don\'t want any spaces before the new line,'
      . ' so it\'s butted up against the left side of the screen.';

return $text;

Regarding the line breaks, with email you should always use \r\n. PHP_EOL is for files that are meant to be used in the same operating system that php is running on.

When configuring log4j.properties, putting org.apache.cxf logging level to INFO is enough to see the plain SOAP messages:

log4j.logger.org.apache.cxf=INFO

DEBUG is too verbose.

LayoutInflater is used to generate dynamic views of the XML for the ListView item or in onCreateView of the fragment.

ConvertView is basically used to recycle the views which are not in the view currently. Say you have a scrollable ListView. On scrolling down or up, the convertView gives the view which was scrolled. This reusage saves memory.

The parent parameter of the getView() method gives a reference to the parent layout which has the listView. Say you want to get the Id of any item in the parent XML you can use:

ViewParent nv = parent.getParent();

while (nv != null) {

    if (View.class.isInstance(nv)) {
        final View button = ((View) nv).findViewById(R.id.remove);
        if (button != null) {
            // FOUND IT!
            // do something, then break;
            button.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Log.d("Remove", "Remove clicked");

                    ((Button) button).setText("Hi");
                }
            });
        }
        break;
    }

 }

Static methods cannot be inherited or overridden, and that is why they can't be abstract. Since static methods are defined on the type, not the instance, of a class, they must be called explicitly on that type. So when you want to call a method on a child class, you need to use its name to call it. This makes inheritance irrelevant.

Assume you could, for a moment, inherit static methods. Imagine this scenario:

public static class Base
{
    public static virtual int GetNumber() { return 5; }
}

public static class Child1 : Base
{
    public static override int GetNumber() { return 1; }
}

public static class Child2 : Base
{
    public static override int GetNumber() { return 2; }
}

If you call Base.GetNumber(), which method would be called? Which value returned? It's pretty easy to see that without creating instances of objects, inheritance is rather hard. Abstract methods without inheritance are just methods that don't have a body, so can't be called.

i wanted to ask if Android Devices uses the network time protocol (ntp) to synchronize the time.

For general time synchronization, devices with telephony capability, where the wireless provider provides NITZ information, will use NITZ. My understanding is that NTP is used in other circumstances: NITZ-free wireless providers, WiFi-only, etc.

Your cited blog post suggests another circumstance: on-demand time synchronization in support of GPS. That is certainly conceivable, though I do not know whether it is used or not.

I solved this by tacking a last modified timestamp as a query parameter to the scripts.

I did this with an extension method, and using it in my CSHTML files. Note: this implementation caches the timestamp for 1 minute so we don't thrash the disk quite so much.

Here is the extension method:

public static class JavascriptExtension {
    public static MvcHtmlString IncludeVersionedJs(this HtmlHelper helper, string filename) {
        string version = GetVersion(helper, filename);
        return MvcHtmlString.Create("<script type='text/javascript' src='" + filename + version + "'></script>");
    }

    private static string GetVersion(this HtmlHelper helper, string filename)
    {
        var context = helper.ViewContext.RequestContext.HttpContext;

        if (context.Cache[filename] == null)
        {
            var physicalPath = context.Server.MapPath(filename);
            var version = $"?v={new System.IO.FileInfo(physicalPath).LastWriteTime.ToString("MMddHHmmss")}";
            context.Cache.Add(filename, version, null,
              DateTime.Now.AddMinutes(5), TimeSpan.Zero,
              CacheItemPriority.Normal, null);
            return version;
        }
        else
        {
            return context.Cache[filename] as string;
        }
    }
}

And then in the CSHTML page:

 @Html.IncludeVersionedJs("/MyJavascriptFile.js")

In the rendered HTML, this appears as:

 <script type='text/javascript' src='/MyJavascriptFile.js?20111129120000'></script>

You won't see a simple answer because there isn't one.

First, Unicode doesn't contain "every character from every language", although it sure does try.

Unicode itself is a mapping, it defines codepoints and a codepoint is a number, associated with usually a character. I say usually because there are concepts like combining characters. You may be familiar with things like accents, or umlauts. Those can be used with another character, such as an a or a u to create a new logical character. A character therefore can consist of 1 or more codepoints.

To be useful in computing systems we need to choose a representation for this information. Those are the various unicode encodings, such as utf-8, utf-16le, utf-32 etc. They are distinguished largely by the size of of their codeunits. UTF-32 is the simplest encoding, it has a codeunit that is 32bits, which means an individual codepoint fits comfortably into a codeunit. The other encodings will have situations where a codepoint will need multiple codeunits, or that particular codepoint can't be represented in the encoding at all (this is a problem for instance with UCS-2).

Because of the flexibility of combining characters, even within a given encoding the number of bytes per character can vary depending on the character and the normalization form. This is a protocol for dealing with characters which have more than one representation (you can say "an 'a' with an accent" which is 2 codepoints, one of which is a combining char or "accented 'a'" which is one codepoint).

It seems that CharEscapers from Google GData-java-client has what you want. It has uriPathEscaper method, uriQueryStringEscaper, and generic uriEscaper. (All return Escaper object which does actual escaping). Apache License.

Your code is correct. I tested:

r = requests.get("http://www.google.com")
print(r.content)

And it returned plenty of content. Check the url, try "http://www.google.com". Cheers!

                handler: { _ in print("Foo") } ))

Delegates are extremely useful when wanting to declare a block of code that you want to pass around. For example when using a generic retry mechanism.

Pseudo:

function Retry(Delegate func, int numberOfTimes)
    try
    {
       func.Invoke();
    }
    catch { if(numberOfTimes blabla) func.Invoke(); etc. etc. }

Or when you want to do late evaluation of code blocks, like a function where you have some Transform action, and want to have a BeforeTransform and an AfterTransform action that you can evaluate within your Transform function, without having to know whether the BeginTransform is filled, or what it has to transform.

And of course when creating event handlers. You don't want to evaluate the code now, but only when needed, so you register a delegate that can be invoked when the event occurs.

Use MoreLINQ, which has a DistinctBy method :)

IEnumerable<Car> distinctCars = cars.DistinctBy(car => car.CarCode);

(This is only for LINQ to Objects, mind you.)

Here I found a tweak for this, without any third party tool. This will make the following shortcut to work:

 fn + right: to go to the end of the line.
 fn + left: to go to the beginning of the line.

• Open terminal preferences.(cmd + ,).
• Go to your selected theme and then to the keyboard tab.
  

• And add a new entry as following.

• That's all. Now close and check.

  Hope it helps.

EDIT: Refer to the comment by @Maurice Gilden below for more insights.

Remove the required: true rule.

Demo: Fiddle

jQuery('.validatedForm').validate({
            rules : {
                password : {
                    minlength : 5
                },
                password_confirm : {
                    minlength : 5,
                    equalTo : "#password"
                }
            }

For those using jQuery there's a convenient method: http://api.jquery.com/change/

In fact, xargs can run commands in parallel for you. There is a special -P max_procs command-line option for that. See man xargs.

sh: http://man.cx/sh
bash: http://man.cx/bash

TL;DR: bash is a superset of sh with a more elegant syntax and more functionality. It is safe to use a bash shebang line in almost all cases as it's quite ubiquitous on modern platforms.

NB: in some environments, sh is bash. Check sh --version.

Another way to do this is described below.

First, turn on iterative calculations on under File - Options - Formulas - Enable Iterative Calculation. Then set maximum iterations to 1000.

After doing this, use the following formula.

=If(D55="","",IF(C55="",NOW(),C55))

Once anything is typed into cell D55 (for this example) then C55 populates today's date and/or time depending on the cell format. This date/time will not change again even if new data is entered into cell C55 so it shows the date/time that the data was entered originally.

This is a circular reference formula so you will get a warning about it every time you open the workbook. Regardless, the formula works and is easy to use anywhere you would like in the worksheet.

A very relevant article is Debugging Heap corruption with Application Verifier and Debugdiag.

Following this doc you can do this that way:

{{ p.User['first_name']|default('NONE') }}

For Microsoft SQL Server you can return the @@ROWCOUNT variable to return the number of rows affected by the last statement in the stored procedure.

There is a slightly better way to access attached files. You could use template reference variable to get an instance of the input element.

Here is an example based on the first answer:

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="file" #file (change)="onChange(file.files)"/>
    </div>
  `,
  providers: [ UploadService ]
})

export class AppComponent {
  onChange(files) {
    console.log(files);
  }
}

Here is an example app to demonstrate this in action.

Template reference variables might be useful, e.g. you could access them via @ViewChild directly in the controller.

Unfortunately, you can only have one app.config file per executable, so if you have DLL’s linked into your application, they cannot have their own app.config files.

Solution is: You don't need to put the App.config file in the Class Library's project.
You put the App.config file in the application that is referencing your class library's dll.

For example, let's say we have a class library named MyClasses.dll which uses the app.config file like so:

string connect = 
ConfigurationSettings.AppSettings["MyClasses.ConnectionString"];

Now, let's say we have an Windows Application named MyApp.exe which references MyClasses.dll. It would contain an App.config with an entry such as:

<appSettings>
    <add key="MyClasses.ConnectionString"
         value="Connection string body goes here" />
</appSettings>

OR

An xml file is best equivalent for app.config. Use xml serialize/deserialize as needed. You can call it what every you want. If your config is "static" and does not need to change, your could also add it to the project as an embedded resource.

Hope it gives some Idea

Maybe the following is what you are looking for:

SELECT name, pathfilename
  FROM table1
  NATURAL JOIN table2
  NATURAL JOIN table3
  WHERE name = 'John';

When using the attribute to restrict the maximum input length for text from a form on a webpage, the StringLength seems to generate the maxlength html attribute (at least in my test with MVC 5). The one to choose then depnds on how you want to alert the user that this is the maximum text length. With the stringlength attribute, the user will simply not be able to type beyond the allowed length. The maxlength attribute doesn't add this html attribute, instead it generates data validation attributes, meaning the user can type beyond the indicated length and that preventing longer input depends on the validation in javascript when he moves to the next field or clicks submit (or if javascript is disabled, server side validation). In this case the user can be notified of the restriction by an error message.

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

Simply type in terminal in your command prompt go to laravel directory path and type php artisan key:generate then key will be generated. Paste that key in config/app.php key variable. Your problem will be solved. I also did like that inorder to solve the problem...

The answer is quite tricky. If you use a plain old Apache Server (or IIS), you get the problem because the Angular pages do not exist for real. They are "computed" from the Angular route.

There are several ways to fix the issue. One is to use the HashLocationStrategy offered by Angular. But a sharp sign is added in the URL. This is mainly for compatibility with Angular 1 (I assume). The fact is the part after the sharp is not part of the URL (then the server resolves the part before the "#" sign). That can be perfect.

Here an enhanced method (based on the 404 trick). I assume you have a "distributed" version of your angular application (ng build --prod if you use Angular-CLI) and you access the pages directly with your server and PHP is enabled.

If your website is based on pages (Wordpress for example) and you have only one folder dedicated to Angular (named "dist" in my example), you can do something weird but, at the end, simple. I assume you have stored your Angular pages in "/dist" (with the according <BASE HREF="/dist/">). Now use a 404 redirection and the help of PHP.

In your Apache configuration (or in the .htaccess file of your angular application directory), you must add ErrorDocument 404 /404.php

The 404.php will start with the following code:

<?php
$angular='/dist/';
if( substr($_SERVER['REQUEST_URI'], 0, strlen($angular)) == $angular ){
    $index = $_SERVER['DOCUMENT_ROOT'] . $angular . "index.html";
    http_response_code(200);
    include $index;
    die;
}

// NOT ANGULAR...
echo "<h1>Not found.</h1>"

where $angular is the value stored in the HREF of your angular index.html.

The principle is quite simple, if Apache does not find the page, a 404 redirection is made to the PHP script. We just check if the page is inside the angular application directory. If it is the case, we just load the index.html directly (without redirecting): this is necessary to keep the URL unchanged. We also change the HTTP code from 404 to 200 (just better for crawlers).

What if the page does not exist in the angular application? Well, we use the "catch all" of the angular router (see Angular router documentation).

This method works with an embedded Angular application inside a basic website (I think it will be the case in future).

NOTES:

• Trying to do the same with the mod_redirect (by rewriting the URLs) is not at all a good solution because files (like assets) have to be really loaded then it is much more risky than just using the "not found" solution.
• Just redirecting using ErrorDocument 404 /dist/index.html works but Apache is still responding with a 404 error code (which is bad for crawlers).

I always prefer to use mixins for small CSS classes like fade in / out incase you want to use them in more than one class.

@mixin fade-in {
    opacity: 1;
    animation-name: fadeInOpacity;
    animation-iteration-count: 1;
    animation-timing-function: ease-in;
    animation-duration: 2s;
}

@keyframes fadeInOpacity {
    0% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

and if you don't want to use mixins, you can create a normal class .fade-in.

The top answer is right, that the error code doesn't give you much info. One of the common causes that we saw in our team for this error code was when the query was not optimized well. A known reason was when we do an inner join with the left side table magnitudes bigger than the table on right side. Swapping these tables would usually do the trick in such cases.

Follow below code for drawable right,left,up,down click:

edittextview_confirmpassword.setOnTouchListener(new View.OnTouchListener() {
    @Override        public boolean onTouch(View v, MotionEvent event) {
        final int DRAWABLE_LEFT = 0;
        final int DRAWABLE_TOP = 1;
        final int DRAWABLE_RIGHT = 2;
        final int DRAWABLE_BOTTOM = 3;

        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() >= (edittextview_confirmpassword.getRight() - edittextview_confirmpassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here                    edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                return true;
            }
        }else{
            edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

        }
        return false;
    }
});

}

You can easy get that effect without using jQueryUI, for example:

$(document).ready(function(){
    $('#slide').click(function(){
    var hidden = $('.hidden');
    if (hidden.hasClass('visible')){
        hidden.animate({"left":"-1000px"}, "slow").removeClass('visible');
    } else {
        hidden.animate({"left":"0px"}, "slow").addClass('visible');
    }
    });
});

Try this working Fiddle:

http://jsfiddle.net/ZQTFq/

insert byte to specific place.

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

Input these code to your SCRATCHPAD and see the action.

var str=String("Blah-Blah1_2,oo0.01&zz%kick").replace(/[^\w-]/ig, '');

Why are LEFT/RIGHT and LEFT OUTER/RIGHT OUTER the same? Let's explain why this vocabulary. Understand that LEFT and RIGHT joins are specific cases of the OUTER join, and therefore couldn't be anything else than OUTER LEFT/OUTER RIGHT. The OUTER join is also called FULL OUTER as opposed to LEFT and RIGHT joins that are PARTIAL results of the OUTER join. Indeed:

Table A | Table B     Table A | Table B      Table A | Table B      Table A | Table B
   1    |   5            1    |   1             1    |   1             1    |   1
   2    |   1            2    |   2             2    |   2             2    |   2
   3    |   6            3    |  null           3    |  null           -    |   -
   4    |   2            4    |  null           4    |  null           -    |   -
                        null  |   5             -    |   -            null  |   5
                        null  |   6             -    |   -            null  |   6

                      OUTER JOIN (FULL)     LEFT OUTER (partial)   RIGHT OUTER (partial)

It is now clear why those operations have aliases, as well as it is clear only 3 cases exist: INNER, OUTER, CROSS. With two sub-cases for the OUTER. The vocabulary, the way teachers explain this, as well as some answers above, often make it looks like there are lots of different types of join. But it's actually very simple.

What worked for me was using the $setSubmitted function, which first shows up in the angular docs in version 1.3.20.

In the click event where I wanted to trigger the validation, I did the following:

vm.triggerSubmit = function() {
    vm.homeForm.$setSubmitted();
    ...
}

That was all it took for me. According to the docs it "Sets the form to its submitted state." It's mentioned here.

The solution is the /Y switch:

xcopy "C:\Users\ADMIN\Desktop\*.*" "D:\Backup\" /K /D /H /Y

There are answers with big number of votes, but when I read your question, I thought you wanted to know the directory where the script is, not that where the script is running. You can get the information with powershell's auto variables

$PSScriptRoot - the directory where the script exists, not the target directory the script is running in
$PSCommandPath - the full path of the script

For example, I have $profile script that finds visual studio solution file and start it. I wanted to store the full path, once a solution file is started. But I wanted to save the file where the original script exists. So I used $PsScriptRoot.

You could code an ES5.1 helper function:

function setAttributes(el, attrs) {
    Object.keys(attrs).forEach(key => el.setAttribute(key, attrs[key]));
}

Call it like this:

setAttributes(elem, { src: 'http://example.com/something.jpeg', height: '100%' });

There is a simpler way, sql timestamp string:

2018-07-19 00:00:00

The closest format to timestamp for Date() to receive is the following, so replace blank space for "T":

var dateString = media.intervention.replace(/\s/g, "T");

"2011-10-10T14:48:00"

Then, create the date object:

var date = new Date(dateString);

result would be the date object:

Thu Jul 19 2018 00:00:00 GMT-0300 (Horário Padrão de Brasília)

If you're looking to scatter by two variables and color by the third, Altair can be a great choice.

Try to use this a very simple way and call it like your own func

public static String convertnumtocharmonths(int m){
         String charname=null;
         if(m==1){
             charname="Jan";
         }
         if(m==2){
             charname="Fev";
         }
         if(m==3){
             charname="Mar";
         }
         if(m==4){

             charname="Mai";
         }
         if(m==6){
             charname="Jun";
         }
         if(m==7){
             charname="Jul";
         }
         if(m==8){

         }
         if(m==9){
             charname="Sep";
         }
         if(m==10){
             charname="Oct";
         }
         if(m==11){
             charname="Nov";
         }
         if(m==12){
             charname="Dec";
         }
         return charname;
     }

import collections

def find_anagrams(x):
    anagrams = [''.join(sorted(list(i))) for i in x]
    anagrams_counts = [item for item, count in collections.Counter(anagrams).items() if count > 1]
    return [i for i in x if ''.join(sorted(list(i))) in anagrams_counts]

you might still run into mysql binary not being found in that manner

open terminal, type
touch ~/.bash_profile; open ~/.bash_profile

edit as follows below, save, quite and restart terminal or alternately

source ~/.bash_profile

to execute new PATH without restarting terminal

and in the fashion of the DavidYell's post above, also add the following. You can stack various variables by exporting them followed by a single PATH export which I demonstrated below

export MAMP_PHP=/Applications/MAMP/bin/php/php5.6.2/bin
export MAMP_BINS=/Applications/MAMP/Library/bin
export USERBINS=~/bins
export PATH="$USERBINS:$MAMP_PHP:$MAMP_BINS:$PATH"

jQuery has a built-in method for this:

$(window).resize(function () { /* do something */ });

For the sake of UI responsiveness, you might consider using a setTimeout to call your code only after some number of milliseconds, as shown in the following example, inspired by this:

function doSomething() {
    alert("I'm done resizing for the moment");
};

var resizeTimer;
$(window).resize(function() {
    clearTimeout(resizeTimer);
    resizeTimer = setTimeout(doSomething, 100);
});

How about

user r = {"",{}};

or

user r = {"",{'\0'}};

or

user r = {"",std::vector<unsigned char>()};

or

user r;

this is the correct answer that worked for me

$(document).ready(function () {
        function resizeIframe() {
            if ($('iframe').contents().find('html').height() > 100) {
                $('iframe').height(($('iframe').contents().find('html').height()) + 'px')
            } else {
                setTimeout(function (e) {
                    resizeIframe();
                }, 50);
            }
        }
        resizeIframe();
    });

To achieve goto-like functionality while keeping the call stack clean, I am using this method:

// in other languages:
// tag1:
// doSomething();
// tag2:
// doMoreThings();
// if (someCondition) goto tag1;
// if (otherCondition) goto tag2;

function tag1() {
    doSomething();
    setTimeout(tag2, 0); // optional, alternatively just tag2();
}

function tag2() {
    doMoreThings();
    if (someCondition) {
        setTimeout(tag1, 0); // those 2 lines
        return;              // imitate goto
    }
    if (otherCondition) {
        setTimeout(tag2, 0); // those 2 lines
        return;              // imitate goto
    }
    setTimeout(tag3, 0); // optional, alternatively just tag3();
}

// ...

Please note that this code is slow since the function calls are added to timeouts queue, which is evaluated later, in browser's update loop.

Please also note that you can pass arguments (using setTimeout(func, 0, arg1, args...) in browser newer than IE9, or setTimeout(function(){func(arg1, args...)}, 0) in older browsers.

AFAIK, you shouldn't ever run into a case that requires this method unless you need to pause a non-parallelable loop in an environment without async/await support.

I had the exact same problem when using Spring Security 3.1.0. and Oracle 11G. I was using the following query and getting the invalid column index error:

<security:jdbc-user-service data-source-ref="dataSource"
                users-by-username-query="SELECT A.user_name AS username, A.password AS password FROM MB_REG_USER A where A.user_name=lower(?)"

It turns out that I needed to add: "1 as enabled" to the query:

<security:jdbc-user-service data-source-ref="dataSource" users-by-username query="SELECT A.user_name AS username, A.password AS password, 1 as enabled FROM MB_REG_USER A where A.user_name=lower(?)"

Everything worked after that. I believe this could be a bug in the Spring JDBC core package...

Let's imagine we have an array of integers like this:

var values = [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];

The average is obtained with the following formula

A= (1/n)Sxi ( with i = 1 to n ) ... So: x1/n + x2/n + ... + xn/n

We divide the current value by the number of values and add the previous result to the returned value.

The reduce method signature is

reduce(callback[,default_previous_value])

The reduce callback function takes the following parameters:

• p : Result of the previous calculation
• c : Current value (from the current index)
• i : Current array element's index value
• a : The current reduced Array

The second reduce's parameter is the default value ... (Used in case the array is empty ).

So the average reduce method will be:

var avg = values.reduce(function(p,c,i,a){return p + (c/a.length)},0);

If you prefer you can create a separate function

function average(p,c,i,a){return p + (c/a.length)};
function sum(p,c){return p + c)};

And then simply refer to the callback method signature

var avg = values.reduce(average,0);
var sum= values.reduce(sum,0);

Or Augment the Array prototype directly..

Array.prototype.sum = Array.prototype.sum || function (){
  return this.reduce(function(p,c){return p+c},0);
};

It's possible to divide the value each time the reduce method is called..

Array.prototype.avg = Array.prototype.avg || function () {
  return this.reduce(function(p,c,i,a){return p+(c/a.length)},0);
};

Or even better , using the previously defined Array.protoype.sum()

method, optimize the process my calling the division only once :)

Array.prototype.avg = Array.prototype.avg || function () {
  return this.sum()/this.length; 
};

Then on any Array object of the scope:

[2, 6].avg();// -> 4
[2, 6].sum();// -> 8

NB: an empty array with return a NaN wish is more correct than 0 in my point of view and can be useful in specific use cases.

App Engine is a Platform-as-a-Service. It means that you simply deploy your code, and the platform does everything else for you. For example, if your app becomes very successful, App Engine will automatically create more instances to handle the increased volume.

Read more about App Engine

Compute Engine is an Infrastructure-as-a-Service. You have to create and configure your own virtual machine instances. It gives you more flexibility and generally costs much less than App Engine. The drawback is that you have to manage your app and virtual machines yourself.

Read more about Compute Engine

You can mix both App Engine and Compute Engine, if necessary. They both work well with the other parts of the Google Cloud Platform.

EDIT (May 2016):

One more important distinction: projects running on App Engine can scale down to zero instances if no requests are coming in. This is extremely useful at the development stage as you can go for weeks without going over the generous free quota of instance-hours. Flexible runtime (i.e. "managed VMs") require at least one instance to run constantly.

EDIT (April 2017):

Cloud Functions (currently in beta) is the next level up from App Engine in terms of abstraction - no instances! It allows developers to deploy bite-size pieces of code that execute in response to different events, which may include HTTP requests, changes in Cloud Storage, etc.

The biggest difference with App Engine is that functions are priced per 100 milliseconds, while App Engine's instances shut down only after 15 minutes of inactivity. Another advantage is that Cloud Functions execute immediately, while a call to App Engine may require a new instance - and cold-starting a new instance may take a few seconds or longer (depending on runtime and your code).

This makes Cloud Functions ideal for (a) rare calls - no need to keep an instance live just in case something happens, (b) rapidly changing loads where instances are often spinning and shutting down, and possibly more use cases.

Your code can do the check, but as you thought, if someone try to access your page using IE v1 or > v19 will not get the error, so might be more safely do the check with Regex expression like this code below:

var userAgent = navigator.userAgent.toLowerCase();
// Test if the browser is IE and check the version number is lower than 9
if (/msie/.test(userAgent) && 
    parseFloat((userAgent.match(/.*(?:rv|ie)[\/: ](.+?)([ \);]|$)/) || [])[1]) < 9) {
  // Navigate to error page
}

Hello I realize this post is old, but here is my opinion anyway. This error arises when you close the console output window using the close icon instead of pressing "any key to continue"

Try installing it somewhere else, maybe that would solve the problem. Also, you could try installing it on a USB flash drive.

just use

git config --global credential.helper store

and do the git pull, it will ask for username and password, from now on it will not provide any prompt for username and password it will store the details

Try IndexOf.

If you look in the obj directory, and you don't see your .exe, it's possible that Avast! or other antivirus is deleting it. I would actually see the .exe show up and then disappear. As soon as I turned off Avast!, problem solved.

VS2010 throwing "Could not copy the file "obj\x86\Debug\[file].exe" because it was not found."

If you can change the signature of your function to async Task then you can use the code presented here

Simply use map function:

var arrOfObj = arrOfObj.map(function(element){
   element.active = true;
   return element;
}

Map is pretty decent on compatibility: you can be reasonably safe from IE <= 9.

However, if you are 100% sure your users will use ES6 Compatible browser, you can shorten that function with arrow functions, as @Sergey Panfilov has suggested.

If you just need swipe, you are better off size wise just using only the part you need. This should work on any touch device.

This is ~450 bytes' after gzip compression, minification, babel etc.

I wrote the below class based on the other answers, it uses percentage moved instead of pixels, and a event dispatcher pattern to hook/unhook things.

Use it like so:

const dispatcher = new SwipeEventDispatcher(myElement);
dispatcher.on('SWIPE_RIGHT', () => { console.log('I swiped right!') })

export class SwipeEventDispatcher {_x000D_
 constructor(element, options = {}) {_x000D_
  this.evtMap = {_x000D_
   SWIPE_LEFT: [],_x000D_
   SWIPE_UP: [],_x000D_
   SWIPE_DOWN: [],_x000D_
   SWIPE_RIGHT: []_x000D_
  };_x000D_
_x000D_
  this.xDown = null;_x000D_
  this.yDown = null;_x000D_
  this.element = element;_x000D_
  this.options = Object.assign({ triggerPercent: 0.3 }, options);_x000D_
_x000D_
  element.addEventListener('touchstart', evt => this.handleTouchStart(evt), false);_x000D_
  element.addEventListener('touchend', evt => this.handleTouchEnd(evt), false);_x000D_
 }_x000D_
_x000D_
 on(evt, cb) {_x000D_
  this.evtMap[evt].push(cb);_x000D_
 }_x000D_
_x000D_
 off(evt, lcb) {_x000D_
  this.evtMap[evt] = this.evtMap[evt].filter(cb => cb !== lcb);_x000D_
 }_x000D_
_x000D_
 trigger(evt, data) {_x000D_
  this.evtMap[evt].map(handler => handler(data));_x000D_
 }_x000D_
_x000D_
 handleTouchStart(evt) {_x000D_
  this.xDown = evt.touches[0].clientX;_x000D_
  this.yDown = evt.touches[0].clientY;_x000D_
 }_x000D_
_x000D_
 handleTouchEnd(evt) {_x000D_
  const deltaX = evt.changedTouches[0].clientX - this.xDown;_x000D_
  const deltaY = evt.changedTouches[0].clientY - this.yDown;_x000D_
  const distMoved = Math.abs(Math.abs(deltaX) > Math.abs(deltaY) ? deltaX : deltaY);_x000D_
  const activePct = distMoved / this.element.offsetWidth;_x000D_
_x000D_
  if (activePct > this.options.triggerPercent) {_x000D_
   if (Math.abs(deltaX) > Math.abs(deltaY)) {_x000D_
    deltaX < 0 ? this.trigger('SWIPE_LEFT') : this.trigger('SWIPE_RIGHT');_x000D_
   } else {_x000D_
    deltaY > 0 ? this.trigger('SWIPE_UP') : this.trigger('SWIPE_DOWN');_x000D_

Excellent answers - here's the D3 version for anyone looking:

<select id="sel">
    <option>Cat</option>
    <option>Dog</option>
    <option>Fish</option>
</select>
<script>
    d3.select('#sel').property('value', 'Fish');
</script>

You can specify USER in the Dockerfile. All subsequent actions will be performed using that account. You can specify USER one line before the CMD or ENTRYPOINT if you only want to use that user when launching a container (and not when building the image). When you start a container from the resulting image, you will attach as the specified user.

Asp.net codebehind runs on server first and then page is rendered to client (browser). Codebehind has no access to client side (javascript, html) because it lives on server only.

So, either use ajax and sent value of label to code behind. You can use PageMethods , or simply post the page to server where codebehind lives, so codebehind can know the updated value :)

You can also try

    interface IData{
        id: number;
        name:string;
    }

    let userTestStatus:Record<string,IData> = {
        "0": { "id": 0, "name": "Available" },
        "1": { "id": 1, "name": "Ready" },
        "2": { "id": 2, "name": "Started" }
    };

To check how record works: https://www.typescriptlang.org/docs/handbook/utility-types.html#recordkt

Here in our case Record is used to declare an object whose key will be a string and whose value will be of type IData so now it will provide us intellisense when we will try to access its property and will throw type error in case we will try something like userTestStatus[0].nameee

You can try color-sampler. It's an easy way to pick color in a canvas. See demo.

Try use Build Timestamp Plugin and use BUILD_TIMESTAMP variable.

I think 2 update calls should do

update VersionedFields
set Value = replace(value,'<iframe','<a><iframe')

update VersionedFields
set Value = replace(value,'> </iframe>','</a>')

Have a look at Determine and count unique values of an array.

Or, to count the number of occurrences of 5, simply do

sum(your_matrix == 5)

I know, all of the previous answers are insightful to your question. I had too like you this confusion just one minute before finding this SO thread. After reading some of the answers, here is what I get: A JSONObject is a JSON-like object that can be represented as an element in the array, the JSONArray. In other words, a JSONArray can contain a (or many) JSONObject.

For iOS 13+

in SceneDelegate:

var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options 
connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = (scene as? UIWindowScene) else { return }
    window = UIWindow(windowScene: windowScene)
    let storyboard = UIStoryboard(name: "Main", bundle: nil) // Where "Main" is the storyboard file name
    let vc = storyboard.instantiateViewController(withIdentifier: "ViewController") // Where "ViewController" is the ID of your viewController
    window?.rootViewController = vc
    window?.makeKeyAndVisible()
}

There might be a fix to <input type="button"> - but if there is, I don't know it.

Otherwise, a good option seems to be to replace it with a carefully styled a element.

Example: http://jsfiddle.net/Uka5v/

.button {
    background-color: #E3E1B8; 
    padding: 2px 4px;
    font: 13px sans-serif;
    text-decoration: none;
    border: 1px solid #000;
    border-color: #aaa #444 #444 #aaa;
    color: #000
}

Upsides include that the a element will style consistently between different (older) versions of Internet Explorer without any extra work, and I think my link looks nicer than that button :)

edited for swift 2

let url = NSURL(string: "http://www.test.com")

    let task = NSURLSession.sharedSession().dataTaskWithURL(url!) {(data, response, error) in
        print(NSString(data: data!, encoding: NSUTF8StringEncoding))
    }

    task.resume()

I found three fixes:

1. You can just load bootsrap first. And them load jquery-ui. But it is not good idea. Because you will see errors in console.

2. This:

   var bootstrapButton = $.fn.button.noConflict();
   $.fn.bootstrapBtn = bootstrapButton;
   

   helps. But other buttons look terrible. And now we don't have bootstrap buttons.

3. I just want to use bootsrap styles and also I want to have close button with an icon. I've done following:

   How close button looks after fix

   .ui-dialog-titlebar-close {
       padding:0 !important;
   }
   
   .ui-dialog-titlebar-close:after {
       content: '';
       width: 20px;
       height: 20px;
       display: inline-block;
       /* Change path to image*/
       background-image: url(themes/base/images/ui-icons_777777_256x240.png);
       background-position: -96px -128px;
       background-repeat: no-repeat;
   }
   

I'm using android:scaleType="fitCenter" with satisfaction.

In English:

• ContentType: When sending data to the server, use this content type. Default is application/x-www-form-urlencoded; charset=UTF-8, which is fine for most cases.
• Accepts: The content type sent in the request header that tells the server what kind of response it will accept in return. Depends on DataType.
• DataType: The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response. Can be text, xml, html, script, json, jsonp.

Alternatively you can use img2pdf to convert images to pdf. Install it on Debian or Ubuntu with:

sudo apt install img2pdf

Convert one or more images to pdf:

img2pdf img.jpg -o output.pdf

It uses a different mechanism than imagemagick to embed the image into the pdf. When possible Img2pdf embeds the image directly into the pdf, without decoding and recoding the image.

In order to center text in md files you can use the center tag like html tag:

<center>Centered text</center>

To H2oRider -- does your application access the Oracle dll in the GAC? What I recommend you do is this: Add the dll to your project and set the build action to "content" and set "copy to output directory" to "copy always".

Then delete your reference(s) to the dll in the GAC. Re-add the reference, but this time drill down to the one you just added to your project.

Now publish it. The application will look for the dll locally, and the dll is included in the deployment so it will find it.

If this doesn't work, then it might be that you can not use that dll if included locally rather than in the GAC. This is true of some assemblies, like the Office PIAs. In that case, the only way to deploy it is to wrap it in a setup & deployment package and use the Bootstrapper Manifest Generator to turn it into a prerequisite you can publish with ClickOnce deployment.

When it comes to areal device, the behavior of devices seem different to a different group of devices.

Some of the strange collection of the opinion I heard form different people is:

• Restart your device after unplugging
• Remove some apps from device and free at-least 100 MB
• Try to install your app from the command line, ./adb install ~Application_path
• Move your application to SD card storage or make it default in SD card in the Android manifest file, android:installLocation="preferExternal"
• You got a lot of memory acquiring stuff in the Raw folder which installs a copy in phone memory while instating an APK file and the device doesn't have enough memory to load them
• Root your device and install some good ROM which help to letting the device know about its remaining memory.

I hope one of them is relevant to you! ;)

Edit (22.06.2016):

Appcompat library started to support material buttons after I posted the original response. In this post you can see the easiest implementation of raised and flat buttons.

Original Answer:

Since that AppCompat doesn't support the button yet you can use xml as backgrounds. For doing that I had a look at the source code of the Android and found the related files for styling material buttons.

1 - Look at the original implementation of material button from source.

Have a look at the btn_default_material.xml on android source code.

You can copy the file into your projects drawable-v21 folder. But don't touch the color attr here. The file you need to change is the second file.

drawable-v21/custom_btn.xml

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?attr/colorControlHighlight">
    <item android:drawable="@drawable/btn_default_mtrl_shape" />
</ripple>

2 - Get the shape of the original material button

As you realise there is a shape used inside this drawable which you can find in this file of the source code.

<inset xmlns:android="http://schemas.android.com/apk/res/android"
   android:insetLeft="@dimen/button_inset_horizontal_material"
   android:insetTop="@dimen/button_inset_vertical_material"
   android:insetRight="@dimen/button_inset_horizontal_material"
   android:insetBottom="@dimen/button_inset_vertical_material">
<shape android:shape="rectangle">
    <corners android:radius="@dimen/control_corner_material" />
    <solid android:color="?attr/colorButtonNormal" />
    <padding android:left="@dimen/button_padding_horizontal_material"
             android:top="@dimen/button_padding_vertical_material"
             android:right="@dimen/button_padding_horizontal_material"
             android:bottom="@dimen/button_padding_vertical_material" />
</shape>

3 - Getting dimensions of the material button

And in this file you there are some dimensions used from the file that you can find here. You can copy the whole file and put into your values folder. This is important for applying the same size (that is used in material buttons) to all buttons

4 - Create another drawable file for old versions

For older versions you should have another drawable with the same name. I am directly putting the items inline instead of referencing. You may want to reference them. But again, the most important thing is the original dimensions of the material button.

drawable/custom_btn.xml

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    
    <!-- pressed state -->
    <item android:state_pressed="true">
        <inset xmlns:android="http://schemas.android.com/apk/res/android"
            android:insetLeft="@dimen/button_inset_horizontal_material"
            android:insetTop="@dimen/button_inset_vertical_material"
            android:insetRight="@dimen/button_inset_horizontal_material"
            android:insetBottom="@dimen/button_inset_vertical_material">
            <shape android:shape="rectangle">
                <corners android:radius="@dimen/control_corner_material" />
                <solid android:color="@color/PRESSED_STATE_COLOR" />
                <padding android:left="@dimen/button_padding_horizontal_material"
                    android:top="@dimen/button_padding_vertical_material"
                    android:right="@dimen/button_padding_horizontal_material"
                    android:bottom="@dimen/button_padding_vertical_material" />
            </shape>
        </inset>
    </item>
    
    <!-- focused state -->
    <item android:state_focused="true">

            android:insetTop="@dimen/button_inset_vertical_material"
            android:insetRight="@dimen/button_inset_horizontal_material"
            android:insetBottom="@dimen/button_inset_vertical_material">
            <shape android:shape="rectangle">
                <corners android:radius="@dimen/control_corner_material" />
                <solid android:color="@color/FOCUSED_STATE_COLOR" />
                <padding android:left="@dimen/button_padding_horizontal_material"
                    android:top="@dimen/button_padding_vertical_material"
                    android:right="@dimen/button_padding_horizontal_material"
                    android:bottom="@dimen/button_padding_vertical_material" />
            </shape>
        </inset>
    </item>
    
    <!-- normal state -->
    <item>
        <inset xmlns:android="http://schemas.android.com/apk/res/android"
            android:insetLeft="@dimen/button_inset_horizontal_material"
            android:insetTop="@dimen/button_inset_vertical_material"
            android:insetRight="@dimen/button_inset_horizontal_material"
            android:insetBottom="@dimen/button_inset_vertical_material">
            <shape android:shape="rectangle">
                <corners android:radius="@dimen/control_corner_material" />
                <solid android:color="@color/NORMAL_STATE_COLOR" />
                <padding android:left="@dimen/button_padding_horizontal_material"
                    android:top="@dimen/button_padding_vertical_material"
                    android:right="@dimen/button_padding_horizontal_material"
                    android:bottom="@dimen/button_padding_vertical_material" />
            </shape>
        </inset>
    </item>
</selector>

Result

Your button will have ripple effect on Lollipop devices. The old versions will have exactly same button except the ripple effect. But since that you provide drawables for different states, they'll also respond to touch events (as the old way).

Here you can see all the avaliable fontFamily values and it's corresponding font file's names(This file is using in android 5.0+). In mobile device, you can find it in:

/system/etc/fonts.xml (for 5.0+)

(For android 4.4 and below using this version, but I think that fonts.xml has a more clear format and easy to understand.)

For example,

    <!-- first font is default -->
20    <family name="sans-serif">
21        <font weight="100" style="normal">Roboto-Thin.ttf</font>
22        <font weight="100" style="italic">Roboto-ThinItalic.ttf</font>
23        <font weight="300" style="normal">Roboto-Light.ttf</font>
24        <font weight="300" style="italic">Roboto-LightItalic.ttf</font>
25        <font weight="400" style="normal">Roboto-Regular.ttf</font>
26        <font weight="400" style="italic">Roboto-Italic.ttf</font>
27        <font weight="500" style="normal">Roboto-Medium.ttf</font>
28        <font weight="500" style="italic">Roboto-MediumItalic.ttf</font>
29        <font weight="900" style="normal">Roboto-Black.ttf</font>
30        <font weight="900" style="italic">Roboto-BlackItalic.ttf</font>
31        <font weight="700" style="normal">Roboto-Bold.ttf</font>
32        <font weight="700" style="italic">Roboto-BoldItalic.ttf</font>
33    </family>

The name attribute name="sans-serif" of family tag defined the value you can use in android:fontFamily.

The font tag define the corresponded font files.

In this case, you can ignore the source under <!-- fallback fonts -->, it's using for fonts' fallback logic.

If you pass a variable data (dictionary type) as context to a template, then you code should be:

{% for key, value in data.items %}
    <p>{{ key }} : {{ value }}</p> 
{% endfor %}
