I have tried using Xcode Devices window's Connect via network options. but I am unable to see the "Connected over the network" icon next to the device name. also as soon as remove the USB the "Connect via network" option disappeared. also, the device name appears under the disconnected device list.

But using the "Connect via IP Address..." option, I am able to connect.

1. Right-click on the device name(Under Disconnected list) and choose "Connect via IP Address...." option.

2. Type the IP address of the device and chose Connect. (you can find through mobile device Settings > Wi-Fi > Choose the wifi name)

If you mean the array indexer,, You overload that just by writing an indexer property.. And you can overload, (write as many as you want) indexer properties as long as each one has a different parameter signature

public class EmployeeCollection: List<Employee>
{
    public Employee this[int employeeId]
    {   
        get 
        { 
            foreach(var emp in this)
            {
                if (emp.EmployeeId == employeeId)
                    return emp;
            }

            return null;
        }
    }

    public Employee this[string employeeName]
    {   
        get 
        { 
            foreach(var emp in this)
            {
                if (emp.Name == employeeName)
                    return emp;
            }

            return null;
        }
    }
}

According to Scott Myers, Effective C++ (3rd ed.) item 42 (which must, of course, be the ultimate answer) - the difference is "nothing".

Advice is to use "class" if it is expected T will always be a class, with "typename" if other types (int, char* whatever) may be expected. Consider it a usage hint.

This nice little bit of code I found by chance, and I have yet to see it suggested on Stack. It only works if the characters you want to remove or alter exist, which is convenient in many scenarios. If the character/s does not exist, it won't alter your NSString:

NSString = [yourString stringByReplacingOccurrencesOfString:@"YOUR CHARACTERS YOU WANT TO REMOVE" withString:@"CAN either be EMPTY or WITH TEXT REPLACEMENT"];

This is how I use it:

//declare what to look for
NSString * suffixTorRemove = @"</p>";
NSString * prefixToRemove = @"<p>";
NSString * randomCharacter = @"</strong>";
NSString * moreRandom = @"<strong>";
NSString * makeAndSign = @"&";

//I AM INSERTING A VALUE FROM A DATABASE AND HAVE ASSIGNED IT TO returnStr
returnStr = [returnStr stringByReplacingOccurrencesOfString:suffixTorRemove withString:@""];
returnStr = [returnStr stringByReplacingOccurrencesOfString:prefixToRemove withString:@""];
returnStr = [returnStr stringByReplacingOccurrencesOfString:randomCharacter withString:@""];
returnStr = [returnStr stringByReplacingOccurrencesOfString:moreRandom withString:@""];
returnStr = [returnStr stringByReplacingOccurrencesOfString:makeAndSign withString:@"&"];

//check the output
NSLog(@"returnStr IS NOW: %@", returnStr);

This one line is super easy to perform three actions in one:

1. Checks your string for the character/s you do not want
2. Can replaces them with whatever you like
3. Does not affect surrounding code

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

I got same issue with

$image_base64 = base64_encode(file_get_contents($_FILES['file']['tmp_name']) );
$image = 'data:image/jpeg;base64,'.$image_base64;
$query = "insert into images(image) values('".$image."')";
mysqli_query($con,$query);

In \xampp\mysql\bin\my.ini file of phpmyadmin we get only

[mysqldump]
max_allowed_packet=110M

which is just for mysqldump -u root -p dbname . I resolved my issue by replacing above code with

max_allowed_packet=110M
[mysqldump]
max_allowed_packet=110M

Based on the answers from this thread it would seem like you could use proxychains to run node.js through the proxy server:
$ proxychains /path/to/node application.js

Personally I wasnt able to install any of the proxychains versions on Cygwin/Windows environment so couldn't test it.

Furthermore, they also talked about using connect-proxy but I could not find any documentation on how to do this.

In short, I'm still stuck, but maybe someone can use this info to find a suitable work-around.

I follow the following instruction to create a executable .jar in Eclipse. Then Run command "java -jar .jar " to launch the program.

It takes care of creating mainfest and includeing main class and library files parts for you.

For demo code that conforms to POSIX standard as described in Setting Terminal Modes Properly and Serial Programming Guide for POSIX Operating Systems, the following is offered.
This code should execute correctly using Linux on x86 as well as ARM (or even CRIS) processors.
It's essentially derived from the other answer, but inaccurate and misleading comments have been corrected.

This demo program opens and initializes a serial terminal at 115200 baud for non-canonical mode that is as portable as possible.
The program transmits a hardcoded text string to the other terminal, and delays while the output is performed.
The program then enters an infinite loop to receive and display data from the serial terminal.
By default the received data is displayed as hexadecimal byte values.

To make the program treat the received data as ASCII codes, compile the program with the symbol DISPLAY_STRING, e.g.

 cc -DDISPLAY_STRING demo.c

If the received data is ASCII text (rather than binary data) and you want to read it as lines terminated by the newline character, then see this answer for a sample program.

For an example of an efficient program that provides buffering of received data yet allows byte-by-byte handing of the input, then see this answer.

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,/;q=0.8

That should be the problem. JSON is served as application/json. If you set the Accept header accordingly, you should get the proper response. (There are browser plugins that let you set headers, I like "Poster" for Firefox best)

You can use them right inline:

var square = 9.4
var floored = floor(square)
var root = sqrt(floored)

println("Starting with \(square), we rounded down to \(floored), then took the square root to end up with \(root)")

As per the official documents, it's not anymore advisable to use matrix class since it will be removed in the future.

https://numpy.org/doc/stable/reference/generated/numpy.matrix.html

As other answers already state that you can achieve all the operations with NumPy arrays.

This command will show all the ports and their destination address:

netstat -f 

Use @Arkaitz Jimenez's code to get two timevals:

#include <sys/time.h>
//...
struct timeval tv1, tv2, diff;

// get the first time:
gettimeofday(&tv1, NULL);

// do whatever it is you want to time
// ...

// get the second time:
gettimeofday(&tv2, NULL);

// get the difference:

int result = timeval_subtract(&diff, &tv1, &tv2);

// the difference is storid in diff now.

Sample code for timeval_subtract can be found at this web site:

 /* Subtract the `struct timeval' values X and Y,
    storing the result in RESULT.
    Return 1 if the difference is negative, otherwise 0.  */

 int
 timeval_subtract (result, x, y)
      struct timeval *result, *x, *y;
 {
   /* Perform the carry for the later subtraction by updating y. */
   if (x->tv_usec < y->tv_usec) {
     int nsec = (y->tv_usec - x->tv_usec) / 1000000 + 1;
     y->tv_usec -= 1000000 * nsec;
     y->tv_sec += nsec;
   }
   if (x->tv_usec - y->tv_usec > 1000000) {
     int nsec = (x->tv_usec - y->tv_usec) / 1000000;
     y->tv_usec += 1000000 * nsec;
     y->tv_sec -= nsec;
   }

   /* Compute the time remaining to wait.
      tv_usec is certainly positive. */
   result->tv_sec = x->tv_sec - y->tv_sec;
   result->tv_usec = x->tv_usec - y->tv_usec;

   /* Return 1 if result is negative. */
   return x->tv_sec < y->tv_sec;
 }

Note that a similar issue can bite you if you use os.path.join() to include an extension that already includes a dot, which is what happens automatically when you use os.path.splitext(). In this example:

components = os.path.splitext(filename)
prefix = components[0]
extension = components[1]
return os.path.join("avatars", instance.username, prefix, extension)

Even though extension might be .jpg you end up with a folder named "foobar" rather than a file called "foobar.jpg". To prevent this you need to append the extension separately:

return os.path.join("avatars", instance.username, prefix) + extension

wtluo, great ! May I propose a slight modification of your code 2. ? Here it is:

for i, detected_box in enumerate(detect_boxes):
    box = detected_box["box"]
    face_img = img[ box[1]:box[1] + box[3], box[0]:box[0] + box[2] ]
    cv2.imwrite("face-{:03d}.jpg".format(i+1), face_img)

It's an optimization of your algorithm that cuts running time.

While a Greedy Algorithm is usually called naive, because it may run multiple times over the same set of data, Dynamic Programming avoids this pitfall through a deeper understanding of the partial results that must be stored to help build the final solution.

A simple example is traversing a tree or a graph only through the nodes that would contribute with the solution, or putting into a table the solutions that you've found so far so you can avoid traversing the same nodes over and over.

Here's an example of a problem that's suited for dynamic programming, from UVA's online judge: Edit Steps Ladder.

I'm going to make quick briefing of the important part of this problem's analysis, taken from the book Programming Challenges, I suggest you check it out.

Take a good look at that problem, if we define a cost function telling us how far appart two strings are, we have two consider the three natural types of changes:

Substitution - change a single character from pattern "s" to a different character in text "t", such as changing "shot" to "spot".

Insertion - insert a single character into pattern "s" to help it match text "t", such as changing "ago" to "agog".

Deletion - delete a single character from pattern "s" to help it match text "t", such as changing "hour" to "our".

When we set each of this operations to cost one step we define the edit distance between two strings. So how do we compute it?

We can define a recursive algorithm using the observation that the last character in the string must be either matched, substituted, inserted or deleted. Chopping off the characters in the last edit operation leaves a pair operation leaves a pair of smaller strings. Let i and j be the last character of the relevant prefix of and t, respectively. there are three pairs of shorter strings after the last operation, corresponding to the string after a match/substitution, insertion or deletion. If we knew the cost of editing the three pairs of smaller strings, we could decide which option leads to the best solution and choose that option accordingly. We can learn this cost, through the awesome thing that's recursion:

#define MATCH 0 /* enumerated type symbol for match */
#define INSERT 1 /* enumerated type symbol for insert */
#define DELETE 2 /* enumerated type symbol for delete */


int string_compare(char *s, char *t, int i, int j)

{

    int k; /* counter */
    int opt[3]; /* cost of the three options */
    int lowest_cost; /* lowest cost */
    if (i == 0) return(j * indel(’ ’));
    if (j == 0) return(i * indel(’ ’));
    opt[MATCH] = string_compare(s,t,i-1,j-1) +
      match(s[i],t[j]);
    opt[INSERT] = string_compare(s,t,i,j-1) +
      indel(t[j]);
    opt[DELETE] = string_compare(s,t,i-1,j) +
      indel(s[i]);
    lowest_cost = opt[MATCH];
    for (k=INSERT; k<=DELETE; k++)
    if (opt[k] < lowest_cost) lowest_cost = opt[k];
    return( lowest_cost );

}

This algorithm is correct, but is also impossibly slow.

Running on our computer, it takes several seconds to compare two 11-character strings, and the computation disappears into never-never land on anything longer.

Why is the algorithm so slow? It takes exponential time because it recomputes values again and again and again. At every position in the string, the recursion branches three ways, meaning it grows at a rate of at least 3^n – indeed, even faster since most of the calls reduce only one of the two indices, not both of them.

So how can we make the algorithm practical? The important observation is that most of these recursive calls are computing things that have already been computed before. How do we know? Well, there can only be |s| · |t| possible unique recursive calls, since there are only that many distinct (i, j) pairs to serve as the parameters of recursive calls.

By storing the values for each of these (i, j) pairs in a table, we can avoid recomputing them and just look them up as needed.

The table is a two-dimensional matrix m where each of the |s|·|t| cells contains the cost of the optimal solution of this subproblem, as well as a parent pointer explaining how we got to this location:

typedef struct {
int cost; /* cost of reaching this cell */
int parent; /* parent cell */
} cell;

cell m[MAXLEN+1][MAXLEN+1]; /* dynamic programming table */

The dynamic programming version has three differences from the recursive version.

First, it gets its intermediate values using table lookup instead of recursive calls.

**Second,**it updates the parent field of each cell, which will enable us to reconstruct the edit sequence later.

**Third,**Third, it is instrumented using a more general goal cell() function instead of just returning m[|s|][|t|].cost. This will enable us to apply this routine to a wider class of problems.

Here, a very particular analysis of what it takes to gather the most optimal partial results, is what makes the solution a "dynamic" one.

Here's an alternate, full solution to the same problem. It's also a "dynamic" one even though its execution is different. I suggest you check out how efficient the solution is by submitting it to UVA's online judge. I find amazing how such a heavy problem was tackled so efficiently.

var d = new Date();
var v = new Date();
v.setMinutes(d.getMinutes()+20);

You can force update your master branch as follows:

git checkout upstreambranch  
git branch master upstreambranch -f    
git checkout master  
git push origin master -f

For the ones who have problem to merge into main branch (Which is the new default one in Github) you can use the following:

git checkout master  
git branch main master -f    
git checkout main  
git push origin main -f

The following command will force both branches to have the same history:

git branch [Branch1] [Branch2] -f 

Using the C# language constructs, you cannot explicitly call the base function from outside the scope of A or B. If you really need to do that, then there is a flaw in your design - i.e. that function shouldn't be virtual to begin with, or part of the base function should be extracted to a separate non-virtual function.

You can from inside B.X however call A.X

class B : A
{
  override void X() { 
    base.X();
    Console.WriteLine("y"); 
  }
}

But that's something else.

As Sasha Truf points out in this answer, you can do it through IL. You can probably also accomplish it through reflection, as mhand points out in the comments.

Steps:

1. Start your remote java application with debugging options as said in above post.
2. Configure Eclipse for remote debugging by specifying host and port.
3. Start remote debugging in Eclipse and wait for connection to succeed.
4. Setup breakpoint and debug.
5. If you want to debug from start of application use suspend=y , this will keep remote application suspended until you connect from eclipse.

See Step by Step guide on Java remote debugging for full details.

If you want to add a class to the first and second td you can use .each() and slice()

$(".location table tbody tr").each(function(){
    $(this).find("td").slice(0, 2).addClass("black");
});

Example on jsfiddle

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.

A simple program to print "N" prime numbers. You can use N value as 100.

    #include  <iostream >
    using  namespace  std;

    int  main()
    {
        int  N;
        cin  >>  N;
        for (int  i =  2;  N > 0;  ++i)
        {
            bool  isPrime  =  true ;
            for (int  j =  2;  j < i;  ++j)
            {
                if (i  % j ==  0)
                {
                    isPrime  =  false ;
                    break ;
                }
            }
            if (isPrime)
            {
                --N;
                cout  <<  i  <<  "\n";
            }
        }
        return  0;
    }

Seems like you posted a new question after you realized that you were dealing with a simpler problem related to size_t. I am glad that you did.

Anyways, You have a .c source file, and most of the code looks as per C standards, except that #include <iostream> and using namespace std;

C equivalent for the built-in functions of C++ standard #include<iostream> can be availed through #include<stdio.h>

1. Replace #include <iostream> with #include <stdio.h>, delete using namespace std;

2. With #include <iostream> taken off, you would need a C standard alternative for cout << endl;, which can be done by printf("\n"); or putchar('\n');
   Out of the two options, printf("\n"); works the faster as I observed.

   When used printf("\n"); in the code above in place of cout<<endl;

   $ time ./thread.exe
   1 2 3 4 5 6 7 8 9 10
   
   real    0m0.031s
   user    0m0.030s
   sys     0m0.030s
   

   When used putchar('\n'); in the code above in place of cout<<endl;

   $ time ./thread.exe
   1 2 3 4 5 6 7 8 9 10
   
   real    0m0.047s
   user    0m0.030s
   sys     0m0.030s

Sorry but that's just much too much overhead (above), short and quick, if you have the MapFragment, you also have to map, just do the following:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            googleMap.setMyLocationEnabled(true)
} else {
    // Show rationale and request permission.
}

Code is in Kotlin, hope you don't mind.

have fun

Btw I think this one is a duplicate of: Show Current Location inside Google Map Fragment

For Windows Server 2012, the solution is very similar to faester's (see above). From the Server Manager, click on Add roles and features, select the appropriate server, then select Features. Under .NET Framework 4.5 Features, you'll see WCF Services, and under that, you'll find HTTP Activation.

Replace "country" with "countrydrop" in your view like this...

Based on comment of @alessandro-pezzato. Run multiples commands by using & between the commands.

Example:

$ sleep 3 & sleep 5 & sleep 2 &

It's will execute the commands in background.

Just a variation on the answers above.

I tried the straight up node command above without success, but the suggestion from this Angular CLI issue worked for me - you create a Node script in your package.json file to increase the memory available to Node when you run your production build.

So if you want to increase the memory available to Node to 4gb (max-old-space-size=4096), your Node command would be node --max-old-space-size=4096 ./node_modules/@angular/cli/bin/ng build --prod. (increase or decrease the amount of memory depending on your needs as well - 4gb worked for me, but you may need more or less). You would then add it to your package.json 'scripts' section like this:

"prod": "node --max-old-space-size=4096 ./node_modules/@angular/cli/bin/ng build --prod"

It would be contained in the scripts object along with the other scripts available - e.g.:

"scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "prod": "node --max-old-space-size=4096./node_modules/@angular/cli/bin/ng build --prod"
}

And you run it by calling npm run prod (you may need to run sudo npm run prod if you're on a Mac or Linux).

Note there may be an underlying issue which is causing Node to need more memory - this doesn't address that if that's the case - but it at least gives Node the memory it needs to perform the build.

You can also pass arguments to getters by returning a function. This is particularly useful when you want to query an array in the store:

getters: {
  // ...
  getTodoById: (state) => (id) => {
    return state.todos.find(todo => todo.id === id)
  }
}
store.getters.getTodoById(2) // -> { id: 2, text: '...', done: false }

Note that getters accessed via methods will run each time you call them, and the result is not cached.

That is called Method-Style Access and it is documented on the Vue.js docs.

You should not be doing this. Instead, do:

test1.py:

 def print_test():
      print "I am a test"
      print "see! I do nothing productive."

service.py

#near the top
from test1 import print_test
#lots of stuff here
print_test()

you need the libblas and liblapack dev packages if you are using Ubuntu.

aptitude install libblas-dev liblapack-dev
pip install scipy

putting NOW() in quotes won't work as Active Records will put escape the NOW() into a string and tries to push it into the db as a string of "NOW()"... you will need to use

$this->db->set('time', 'NOW()', FALSE); 

to set it correctly.

you can always check your sql afterward with

$this->db->last_query();

Summarize other answer and what I know all ways to do this using a one-liner:

   String testString = "a.b.c.d";

1) Using Apache Commons

int apache = StringUtils.countMatches(testString, ".");
System.out.println("apache = " + apache);

2) Using Spring Framework's

int spring = org.springframework.util.StringUtils.countOccurrencesOf(testString, ".");
System.out.println("spring = " + spring);

3) Using replace

int replace = testString.length() - testString.replace(".", "").length();
System.out.println("replace = " + replace);

4) Using replaceAll (case 1)

int replaceAll = testString.replaceAll("[^.]", "").length();
System.out.println("replaceAll = " + replaceAll);

5) Using replaceAll (case 2)

int replaceAllCase2 = testString.length() - testString.replaceAll("\\.", "").length();
System.out.println("replaceAll (second case) = " + replaceAllCase2);

6) Using split

int split = testString.split("\\.",-1).length-1;
System.out.println("split = " + split);

7) Using Java8 (case 1)

long java8 = testString.chars().filter(ch -> ch =='.').count();
System.out.println("java8 = " + java8);

8) Using Java8 (case 2), may be better for unicode than case 1

long java8Case2 = testString.codePoints().filter(ch -> ch =='.').count();
System.out.println("java8 (second case) = " + java8Case2);

9) Using StringTokenizer

int stringTokenizer = new StringTokenizer(" " +testString + " ", ".").countTokens()-1;
System.out.println("stringTokenizer = " + stringTokenizer);

From comment: Be carefull for the StringTokenizer, for a.b.c.d it will work but for a...b.c....d or ...a.b.c.d or a....b......c.....d... or etc. it will not work. It just will count for . between characters just once

Update

Based on Manipulating the browser history, passing the empty string as second parameter of pushState method (aka title) should be safe against future changes to the method, so it's better to use pushState like this:

history.pushState(null, '', '/en/step2');    

You can read more about that in mentioned article

Original Answer

Use history.pushState like this:

history.pushState(null, null, '/en/step2');

• More info (MDN article): Manipulating the browser history
• Can I use
• Maybe you should take a look @ Does Internet Explorer support pushState and replaceState?

Update 2 to answer Idan Dagan's comment:

Why not using history.replaceState()?

From MDN

history.replaceState() operates exactly like history.pushState() except that replaceState() modifies the current history entry instead of creating a new one

That means if you use replaceState, yes the url will be changed but user can not use Browser's Back button to back to prev. state(s) anymore (because replaceState doesn't add new entry to history) and it's not recommended and provide bad UX.

Update 3 to add window.onpopstate

So, as this answer got your attention, here is additional info about manipulating the browser history, after using pushState, you can detect the back/forward button navigation by using window.onpopstate like this:

window.onpopstate = function(e) {
    // ... 
};

As the first argument of pushState is an object, if you passed an object instead of null, you can access that object in onpopstate which is very handy, here is how:

window.onpopstate = function(e) {
    if(e.state) {
        console.log(e.state);
    }
};

Update 4 to add Reading the current state:

When your page loads, it might have a non-null state object, you can read the state of the current history entry without waiting for a popstate event using the history.state property like this:

console.log(history.state);

Bonus: Use following to check history.pushState support:

if (history.pushState) {
  // \o/
}

So to fix this properly, I did what others here did and used css to get hide the horizontal toolbar:

.name {
  max-width: 100%;
  overflow-x: hidden;
}

Then in js, I created an event listener to look for scrolling, and counteracted the users attempted horizontal scroll.

var scrollEventHandler = function()
{
  window.scroll(0, window.pageYOffset)
}

window.addEventListener("scroll", scrollEventHandler, false);

I saw somebody do something similar, but apparently that didn't work. This however is working perfectly fine for me.

In PCRE \R matches \n, \r and \r\n.

1. The input tag doesn't have onsubmit handler. Instead, you should put your onsubmit handler on actual form tag, like this:
   
   <form name="loginform" onsubmit="validateForm()" method="post">
   
   Here are some useful links:

   • JavaScript Form Validation
   • Form onsubmit Event

2. For the form tag you can specify the request method, GET or POST. By default, the method is GET. One of the differences between them is that in case of GET method, the parameters are appended to the URL (just what you have shown), while in case of POST method there are not shown in URL.

   You can read more about the differences here.

UPDATE:

You should return the function call and also you can specify the URL in action attribute of form tag. So here is the updated code:

<form name="loginform" onSubmit="return validateForm();" action="main.html" method="post">
    <label>User name</label>
    <input type="text" name="usr" placeholder="username"> 
    <label>Password</label>
    <input type="password" name="pword" placeholder="password">
    <input type="submit" value="Login"/>
</form>

<script>
    function validateForm() {
        var un = document.loginform.usr.value;
        var pw = document.loginform.pword.value;
        var username = "username"; 
        var password = "password";
        if ((un == username) && (pw == password)) {
            return true;
        }
        else {
            alert ("Login was unsuccessful, please check your username and password");
            return false;
        }
  }
</script>

Here is a snippet that does not need ajQuery and will enable alerts in a disabled iframe (like on codepen)

for (var i = 0; i < document.getElementsByTagName('iframe').length; i++) {
    document.getElementsByTagName('iframe')[i].setAttribute('sandbox','allow-modals');
}

Here is a codepen demo working with an alert() after this fix as well: http://codepen.io/nicholasabrams/pen/vNpoBr?editors=001

A version using MSHTA and javascript. Change %jsfunc% to whateve jscript function you want to call

@echo off
::Invoke a javascript function using mhta

set jsfunc=new Date().getDay()
set dialog="about:<script>resizeTo(0,0);new ActiveXObject('Scripting.FileSystemObject').
set dialog=%dialog%GetStandardStream(1).WriteLine(%jsfunc%);close();</script>"

for /f "tokens=* delims=" %%p in ('mshta.exe %dialog%') do set ndow=%%p

::get dow string from array of strings  
for /f "tokens=%ndow%"  %%d in ("Mon Tue Wed Thu Fri Sat Sun") do set dow=%%d 

echo dow is : %ndow%  %dow%
pause

In my case adding following lines to lambda.js {my deployed is on AWS Lambda} fixed the issue.

 'font/opentype',
 'font/sfnt',
 'font/ttf',
 'font/woff',
 'font/woff2'

public static void main(String[] args) {
    Calendar cal = Calendar.getInstance();
    cal.set(year, month, date);
    SimpleDateFormat format1 = new SimpleDateFormat("yyyy MM dd");
    String formatted = format1.format(cal.getTime());
    System.out.println(formatted);
}

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

I've done it finaly check it and if there is a better way tell me guys

For WAMP 3.0 : Click Structure Below Add 1 Column you will see '- Indexes' Click -Indexes and drop whichever index you want.

Nice answers abowe, but don't forget one IMPORTANT thing - they provide different results!

  var idList = new int[1, 2, 2, 2, 2]; // same user is selected 4 times
  var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e)).ToList();

This will return 2 rows from DB (and this could be correct, if you just want a distinct sorted list of users)

BUT in many cases, you could want an unsorted list of results. You always have to think about it like about a SQL query. Please see the example with eshop shopping cart to illustrate what's going on:

  var priceListIDs = new int[1, 2, 2, 2, 2]; // user has bought 4 times item ID 2
  var shoppingCart = _dataContext.ShoppingCart
                     .Join(priceListIDs, sc => sc.PriceListID, pli => pli, (sc, pli) => sc)
                     .ToList();

This will return 5 results from DB. Using 'contains' would be wrong in this case.

Try this:

  $(document).on('click','#save',function(e) {
  var data = $("#form-search").serialize();
  $.ajax({
         data: data,
         type: "post",
         url: "insertmail.php",
         success: function(data){
              alert("Data Save: " + data);
         }
});
 });

and in insertmail.php:

<?php 
if(isset($_REQUEST))
{
        mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);

$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
}
?>

Don't use mysql_ it's deprecated.

another method:

Actually if your problem is null value inserted into the database then try this and here no need of ajax.

<?php
if($_POST['email']!="")
{
    mysql_connect("localhost","root","");
    mysql_select_db("eciticket_db");
    error_reporting(E_ALL && ~E_NOTICE);
    $email=$_POST['email'];
    $sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
    $result=mysql_query($sql);
    if($result){
    //echo "You have been successfully subscribed.";
              setcookie("msg","You have been successfully subscribed.",time()+5,"/");
              header("location:yourphppage.php");
    }
     if(!$sql)
    die(mysql_error());
    mysql_close();
}
?>
    <?php if(isset($_COOKIE['msg'])){?>
       <span><?php echo $_COOKIE['msg'];setcookie("msg","",time()-5,"/");?></span> 
    <?php }?>
<form id="form-search" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">
    <span><span class="style2">Enter you email here</span>:</span>
    <input name="email" type="email" id="email" required/>
    <input type="submit" value="subscribe" class="submit"/>
</form>

As far as I remember, this is controlled by browser settings. In other words: user can chose whether they would like to open new tab in the background or foreground. Also they can chose whether new popup should open in new tab or just... popup.

For example in firefox preferences:

Notice the last option.

This warning is useful for programmers that would mistakenly write 'test' where they should have written "test".

This happen much more often than programmers that do actually want multi-char int constants.

You could use multiple approaches and see if they converge to the same answer. Or grab some from the 'net. The Chudnovsky algorithm is usually used as a very fast method of calculating pi. http://www.craig-wood.com/nick/articles/pi-chudnovsky/

Yes, it is intended. Here you can read detailed explanation. It is possible to override this behavior by setting SO_REUSEADDR option on a socket. For example:

sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

From your shell run:

pip2 install unicodecsv

And (unlike the original question) presuming you're using Python's built in csv module, turn
import csv into
import unicodecsv as csv in your code.

I had this problem and it turned out I was trying to restore to the wrong version of SQL. If you want more information on what's going on, try restoring the database using the following SQL:

RESTORE DATABASE <YourDatabase> 
FROM DISK='<the path to your backup file>\<YourDatabase>.bak'

That should give you the error message that you need to debug this.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

The OOM exception could be avoided by following the official guide to load large bitmap.

Don't run your code on the UI Thread. Use AsyncTask instead and you should be fine.

This issue turned up for me when I was trying to find a similar answer. Consider:

    $('.ui-dialog').wrap('<div class="abc" />');

Where abc is the name of your 'CSS wrapper' - see Stack Overflow question Custom CSS scope and jQuery UI dialog themes where I found the answer from Evgeni Nabokov. For more information on the CSS wrapper in use with a jQuery UI dialog box - see the following (but note they do NOT really solve the issue of the CSS wrapper with the dialog box - you need the above comments to help there, Using Multiple jQuery UI Themes on a Single Page (Filament blog).

Please don't use printf("%s", your_string.c_str());

Use cout << your_string; instead. Short, simple and typesafe. In fact, when you're writing C++, you generally want to avoid printf entirely -- it's a leftover from C that's rarely needed or useful in C++.

As to why you should use cout instead of printf, the reasons are numerous. Here's a sampling of a few of the most obvious:

1. As the question shows, printf isn't type-safe. If the type you pass differs from that given in the conversion specifier, printf will try to use whatever it finds on the stack as if it were the specified type, giving undefined behavior. Some compilers can warn about this under some circumstances, but some compilers can't/won't at all, and none can under all circumstances.
2. printf isn't extensible. You can only pass primitive types to it. The set of conversion specifiers it understands is hard-coded in its implementation, and there's no way for you to add more/others. Most well-written C++ should use these types primarily to implement types oriented toward the problem being solved.

3. It makes decent formatting much more difficult. For an obvious example, when you're printing numbers for people to read, you typically want to insert thousands separators every few digits. The exact number of digits and the characters used as separators varies, but cout has that covered as well. For example:

   std::locale loc("");
   std::cout.imbue(loc);
   
   std::cout << 123456.78;
   

   The nameless locale (the "") picks a locale based on the user's configuration. Therefore, on my machine (configured for US English) this prints out as 123,456.78. For somebody who has their computer configured for (say) Germany, it would print out something like 123.456,78. For somebody with it configured for India, it would print out as 1,23,456.78 (and of course there are many others). With printf I get exactly one result: 123456.78. It is consistent, but it's consistently wrong for everybody everywhere. Essentially the only way to work around it is to do the formatting separately, then pass the result as a string to printf, because printf itself simply will not do the job correctly.

4. Although they're quite compact, printf format strings can be quite unreadable. Even among C programmers who use printf virtually every day, I'd guess at least 99% would need to look things up to be sure what the # in %#x means, and how that differs from what the # in %#f means (and yes, they mean entirely different things).

As of React 0.15, the most concise method is:

<input ref={input => input && input.focus()}/>

As from Laravel 5.5 you can use firstWhere()

In you case:

$green_foods = $foods->firstWhere('color', 'green');

If you're using JNA, you can do thisPlatform.is64Bit().

I got the same error, when I was trying to import matplotlib.pyplot

In [1]: import matplotlib.pyplot as plt
...
...
ImportError: No module named PyQt4.QtCore

But in my case the problem was due to a missing linux library libGL.so.1

OS : Cent OS 64 bit

Python version : 3.5.2

$> locate libGL.so.1

If this command returns a value, your problem could be different, so please ignore my answer. If it does not return any value and your environment is same as mine, below steps would fix your problem.

$> yum install mesa-libGL.x86_64

This installs the necessary OpenGL libraries for 64 bit Cent OS.

$> locate libGL.so.1
/usr/lib/libGL.so.1

Now go back to iPython and try to import

In [1]: import matplotlib.pyplot as plt

This time it imported successfully.

I warmly recommend Red Gate's SQL Prompt. Auto-discovery (intellisense on tables, stored procedures, functions and native functions) is nothing short of awesome! :)

It comes with a price though. There is no free-ware version of the thing.

An API is a set of commands, functions, and protocols which programmers can use when building software for a specific OS or any other software. The API allows programmers to use predefined functions to interact with the operating system, instead of writing them from scratch. All computer operating systems, such as Windows, Unix, and the Mac OS and language such as Java provide an application program interface for programmers.

I prefer Verification and Permissions to Authentication and Authorization.

It is easier in my head and in my code to think of "verification" and "permissions" because the two words

• don't sound alike
• don't have the same abbreviation

Authentication is verification and Authorization is checking permission(s). Auth can mean either, but is used more often as "User Auth" i.e. "User Authentication"

There is preprocessor for Java which provides directives like #define, #ifdef, #ifndef and many others, for instance PostgresJDBC team uses it to generate sources for different cases and to not duplicate code.

Yes you can do so and I have created a library for the same.
This allows you to connect up-to four devices to the main server device creating different channels for each client and running interactions on different threads.
To use this library simple add compile com.mdg.androble:library:0.1.2 in dependency section of your build.gradle .

Take a look at Blaze-Persistence Entity Views which works on top of JPA and provides first class DTO support. You can project anything to attributes within Entity Views and it will even reuse existing join nodes for associations if possible.

Here is an example mapping

@EntityView(Order.class)
interface OrderSummary {
  Integer getId();
  @Mapping("SUM(orderPositions.price * orderPositions.amount * orderPositions.tax)")
  BigDecimal getOrderAmount();
  @Mapping("COUNT(orderPositions)")
  Long getItemCount();
}

Fetching this will generate a JPQL/HQL query similar to this

SELECT
  o.id,
  SUM(p.price * p.amount * p.tax),
  COUNT(p.id)
FROM
  Order o
LEFT JOIN
  o.orderPositions p
GROUP BY
  o.id

Here is a blog post about custom subquery providers which might be interesting to you as well: https://blazebit.com/blog/2017/entity-view-mapping-subqueries.html

If you want only the line number do this:

grep -n Pattern file.ext | gawk '{print $1}' FS=":"

Example:

$ grep -n 9780545460262 EXT20130410.txt | gawk '{print $1}' FS=":"

You need to correctly set up your flutter path.

from here https://flutter.dev/docs/get-started/install/macos#update-your-path

1. Determine the directory where you placed the Flutter SDK. You will need this in Step 3.
2. Open (or create) $HOME/.bash_profile. You can do that by using terminal text editor by going in terminal and typing nano ~/.bash_profile

macOS Catalina uses the Z shell by default, so edit $HOME/.zshrc.

If you are using a different shell, the file path and filename will be different on your machine.

3. Add the following line and change [PATH_TO_FLUTTER_GIT_DIRECTORY] to be the path where you cloned Flutter’s git repo:

export PATH=[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin:$PATH

for example:

export PATH=~/Documents/flutter/bin:$PATH

4. press CTRL X and when it asked you to save the file, choose yes

5. Run source $HOME/.bash_profile to refresh the current window or restart the terminal

6. Verify that the flutter/bin directory is now in your PATH by running: echo $PATH

Notice that [PATH_TO_FLUTTER_GIT_DIRECTORY] is where you installed flutter SDK, not the location of your app

Instead of nano, you can use any text editor to edit ~/.bash_profile

The following works by starting the jar with a batch file, in case the program runs as a stand alone:

public static void startExtJarProgram(){
        String extJar = Paths.get("C:\\absolute\\path\\to\\batchfile.bat").toString();
        ProcessBuilder processBuilder = new ProcessBuilder(extJar);
        processBuilder.redirectError(new File(Paths.get("C:\\path\\to\\JavaProcessOutput\\extJar_out_put.txt").toString()));
        processBuilder.redirectInput();
        try {
           final Process process = processBuilder.start();
            try {
                final int exitStatus = process.waitFor();
                if(exitStatus==0){
                    System.out.println("External Jar Started Successfully.");
                    System.exit(0); //or whatever suits 
                }else{
                    System.out.println("There was an error starting external Jar. Perhaps path issues. Use exit code "+exitStatus+" for details.");
                    System.out.println("Check also C:\\path\\to\\JavaProcessOutput\\extJar_out_put.txt file for additional details.");
                    System.exit(1);//whatever
                }
            } catch (InterruptedException ex) {
                System.out.println("InterruptedException: "+ex.getMessage());
            }
        } catch (IOException ex) {
            System.out.println("IOException. Faild to start process. Reason: "+ex.getMessage());
        }
        System.out.println("Process Terminated.");
        System.exit(0);
    }

In the batchfile.bat then we can say:

@echo off
start /min C:\path\to\jarprogram.jar

Late to the party, but may help for coming users -

I got this issue when i select a record using getsession() and again update another record with same identifier using same session causes the issue. Added code below.

Customer existingCustomer=getSession().get(Customer.class,1);
Customer customerFromUi;// This customer details comiong from UI with identifer 1

getSession().update(customerFromUi);// Here the issue comes

This should never be done . Solution is either evict session before update or change business logic.

Below is the code that read the data from the text file and sends it to the handler for processing and receive the response data from the handler and read it and store the data in the string builder class

 //Get the data from text file that needs to be sent.
                FileStream fileStream = new FileStream(@"G:\Papertest.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite);
                byte[] buffer = new byte[fileStream.Length];
                int count = fileStream.Read(buffer, 0, buffer.Length);

                //This is a handler would recieve the data and process it and sends back response.
                WebRequest myWebRequest = WebRequest.Create(@"http://localhost/Provider/ProcessorHandler.ashx");

                myWebRequest.ContentLength = buffer.Length;
                myWebRequest.ContentType = "application/octet-stream";
                myWebRequest.Method = "POST";
                // get the stream object that holds request stream.
                Stream stream = myWebRequest.GetRequestStream();
                       stream.Write(buffer, 0, buffer.Length);
                       stream.Close();

                //Sends a web request and wait for response.
                try
                {
                    WebResponse webResponse = myWebRequest.GetResponse();
                    //get Stream Data from the response
                    Stream respData = webResponse.GetResponseStream();
                    //read the response from stream.
                    StreamReader streamReader = new StreamReader(respData);
                    string name;
                    StringBuilder str = new StringBuilder();
                    while ((name = streamReader.ReadLine()) != null)
                    {
                        str.Append(name); // Add to stringbuider when response contains multple lines data
                   }
                }
                catch (Exception ex)
                {
                    throw ex;
                }

On MSDN, the documentation for Task.Run Method (Action) provides this example which shows how to run a method asynchronously from main:

using System;
using System.Threading;
using System.Threading.Tasks;

public class Example
{
    public static void Main()
    {
        ShowThreadInfo("Application");

        var t = Task.Run(() => ShowThreadInfo("Task") );
        t.Wait();
    }

    static void ShowThreadInfo(String s)
    {
        Console.WriteLine("{0} Thread ID: {1}",
                          s, Thread.CurrentThread.ManagedThreadId);
    }
}
// The example displays the following output:
//       Application thread ID: 1
//       Task thread ID: 3

Note this statement that follows the example:

The examples show that the asynchronous task executes on a different thread than the main application thread.

So, if instead you want the task to run on the main application thread, see the answer by @StephenCleary.

And regarding the thread on which the task runs, also note Stephen's comment on his answer:

You can use a simple Wait or Result, and there's nothing wrong with that. But be aware that there are two important differences: 1) all async continuations run on the thread pool rather than the main thread, and 2) any exceptions are wrapped in an AggregateException.

(See Exception Handling (Task Parallel Library) for how to incorporate exception handling to deal with an AggregateException.)

Finally, on MSDN from the documentation for Task.Delay Method (TimeSpan), this example shows how to run an asynchronous task that returns a value:

using System;
using System.Threading.Tasks;

public class Example
{
    public static void Main()
    {
        var t = Task.Run(async delegate
                {
                    await Task.Delay(TimeSpan.FromSeconds(1.5));
                    return 42;
                });
        t.Wait();
        Console.WriteLine("Task t Status: {0}, Result: {1}",
                          t.Status, t.Result);
    }
}
// The example displays the following output:
//        Task t Status: RanToCompletion, Result: 42

Note that instead of passing a delegate to Task.Run, you can instead pass a lambda function like this:

var t = Task.Run(async () =>
        {
            await Task.Delay(TimeSpan.FromSeconds(1.5));
            return 42;
        });

You can check the local and global value of it with:

SELECT @@SQL_MODE, @@GLOBAL.SQL_MODE;

I just hit this too. Turns out that at least for me, this was due to trying to use a win64 version of the JRE with a win32 Eclipse. I seems that win32 Eclipse requires a win32 Java (what is called -586 in the list of Java installers from Oracle/Sun).

The reason I was using both is that I was trying to pinpoint a bug that only manifested itself in 64-bit Eclipse, so I needed a 32-bit to compare to.

Once I installed BOTH the "x64" (win64) and "i586" (win32) versions of the JRE on my machine, things work fine and no error 13. You can apparently have both installed at the same time.

Check out Apache Ant

It's possible to use Ant for automatic builds with eclipse, here's how

Static constructors are also very useful when you have static fields that rely upon each other such that the order of initialization is important. If you run your code through a formatter/beautifier that changes the order of the fields then you may find yourself with null values where you didn't expect them.

Example: Suppose we had this class:

class ScopeMonitor
{
    static string urlFragment = "foo/bar";
    static string firstPart= "http://www.example.com/";
    static string fullUrl= firstPart + urlFragment;
}

When you access fullUr, it will be "http://www.example.com/foo/bar".

Months later you're cleaning up your code and alphabetize the fields (let's say they're part of a much larger list, so you don't notice the problem). You have:

class ScopeMonitor
{
    static string firstPart= "http://www.example.com/";
    static string fullUrl= firstPart + urlFragment;
    static string urlFragment = "foo/bar";
}

Your fullUrl value is now just "http://www.example.com/" since urlFragment hadn't been initialized at the time fullUrl was being set. Not good. So, you add a static constructor to take care of the initialization:

class ScopeMonitor
{
    static string firstPart= "http://www.example.com/";
    static string fullUrl;
    static string urlFragment = "foo/bar";

    static ScopeMonitor()
    {
        fullUrl= firstPart + urlFragment;

    }
}

Now, no matter what order you have the fields, the initialization will always be correct.

another way to implement singleton in c#, i personally prefer this way because you can access the instance of the singeton class as a property instead of a method.

public class Singleton
    {
        private static Singleton instance;

        private Singleton() { }

        public static Singleton Instance
        {
            get
            {
                if (instance == null)
                    instance = new Singleton();
                return instance;
            }
        }

        //instance methods
    }

but well, as far as i know both ways are considered 'right' so it's just a thing of personal flavor.

you can use jquery validator for that but you need to add jquery.validate.js and jquery.form.js file for that. after including validator file define your validation something like this.

<script type="text/javascript">
$(document).ready(function(){
    $("#formID").validate({
    rules :{
        "data[User][name]" : {
            required : true
        }
    },
    messages :{
        "data[User][name]" : {
            required : 'Enter username'
        }
    }
    });
});
</script>

You can see required : true same there is many more property like for email you can define email : true for number number : true

I got this error message when I entered a number (999999) that was out of the range I'd set for the form.

Drawing text in plain OpenGL isn't a straigth-forward task. You should probably have a look at libraries for doing this (either by using a library or as an example implementation).

Some good starting points could be GLFont, OpenGL Font Survey and NeHe Tutorial for Bitmap Fonts (Windows).

Note that bitmaps are not the only way of achieving text in OpenGL as mentioned in the font survey.

The concept is storing persistent data across page loads for a web visitor. Cookies store it directly on the client. Sessions use a cookie as a key of sorts, to associate with the data that is stored on the server side.

It is preferred to use sessions because the actual values are hidden from the client, and you control when the data expires and becomes invalid. If it was all based on cookies, a user (or hacker) could manipulate their cookie data and then play requests to your site.

Edit: I don't think there is any advantage to using cookies, other than simplicity. Look at it this way... Does the user have any reason to know their ID#? Typically I would say no, the user has no need for this information. Giving out information should be limited on a need to know basis. What if the user changes his cookie to have a different ID, how will your application respond? It's a security risk.

Before sessions were all the rage, I basically had my own implementation. I stored a unique cookie value on the client, and stored my persistent data in the database along with that cookie value. Then on page requests I matched up those values and had my persistent data without letting the client control what that was.

Use android-apktool

There is an application that reads apk files and decodes XMLs to nearly original form.

Usage:

apktool d Gmail.apk && cat Gmail/AndroidManifest.xml

Suppose I have the following table T:

a   b
--------
1   abc
1   def
1   ghi
2   jkl
2   mno
2   pqr

And I do the following query:

SELECT a, b
FROM T
GROUP BY a

The output should have two rows, one row where a=1 and a second row where a=2.

But what should the value of b show on each of these two rows? There are three possibilities in each case, and nothing in the query makes it clear which value to choose for b in each group. It's ambiguous.

This demonstrates the single-value rule, which prohibits the undefined results you get when you run a GROUP BY query, and you include any columns in the select-list that are neither part of the grouping criteria, nor appear in aggregate functions (SUM, MIN, MAX, etc.).

Fixing it might look like this:

SELECT a, MAX(b) AS x
FROM T
GROUP BY a

Now it's clear that you want the following result:

a   x
--------
1   ghi
2   pqr

I used flutter to create iOS project. When build for Simulator, failed with the same error message. It is solved by following work.

xCode 12.3 Build Settings->Build Active Architecture Only, set it to Yes.

If, like me, you are doing this for a column which then goes through COALESCE / array_to_json / ARRAY_AGG / row_to_json (PostgreSQL) and want to keep the capitals in the column name, double quote the column name, like so:

SELECT a.price AS "myFirstPrice", b.price AS "mySecondPrice"

Without the quotes (and when using those functions), my column names in camelCase would lose the capital letters.

Note that Git 2.5 (Q2 2015) a future Git might try to make that scenario impossible.

stash: require a clean index to apply/pop

Problem

If you have staged contents in your index and run "stash apply/pop", we may hit a conflict and put new entries into the index.
Recovering to your original state is difficult at that point, because tools like "git reset --keep" will blow away anything staged.

In other words:

"git stash pop/apply" forgot to make sure that not just the working tree is clean but also the index is clean.
The latter is important as a stash application can conflict and the index will be used for conflict resolution.

Solution

We can make this safer by refusing to apply when there are staged changes.

That means if there were merges before because of applying a stash on modified files (added but not committed), now they would not be any merges because the stash apply/pop would stop immediately with:

Cannot apply stash: Your index contains uncommitted changes.

Forcing you to commit the changes means that, in case of merges, you can easily restore the initial state( before git stash apply/pop) with a git reset --hard.

See commit 1937610 (15 Jun 2015), and commit ed178ef (22 Apr 2015) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit bfb539b, 24 Jun 2015)}

That commit was an attempt to improve the safety of applying a stash, because the application process may create conflicted index entries, after which it is hard to restore the original index state.

Unfortunately, this hurts some common workflows around "git stash -k", like:

git add -p       ;# (1) stage set of proposed changes
git stash -k     ;# (2) get rid of everything else
make test        ;# (3) make sure proposal is reasonable
git stash apply  ;# (4) restore original working tree

If you "git commit" between steps (3) and (4), then this just works. However, if these steps are part of a pre-commit hook, you don't have that opportunity (you have to restore the original state regardless of whether the tests passed or failed).

I found this piece of code more understadable and working:

public static boolean deleteDir(File dir) {
    if (dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
    }

    return dir.delete(); // The directory is empty now and can be deleted.
}

Like so?

static void Main()
{
    byte[] data = FromHex("47-61-74-65-77-61-79-53-65-72-76-65-72");
    string s = Encoding.ASCII.GetString(data); // GatewayServer
}
public static byte[] FromHex(string hex)
{
    hex = hex.Replace("-", "");
    byte[] raw = new byte[hex.Length / 2];
    for (int i = 0; i < raw.Length; i++)
    {
        raw[i] = Convert.ToByte(hex.Substring(i * 2, 2), 16);
    }
    return raw;
}

Buffer contains metadata which helps improve write performance

Cache contains the file content itself (sometimes yet to write to disk) which improves read performance

A bit late but I thought I'd share in case it helps anyone: what is most likely the problem is simply that your Debug Console (the command line window that opens when run your project if it is a Windows Console Application) is still open from the last time you ran the code. Just close that window, then rebuild and run: Ctrl + B and F5, respectively.

Try:

import java.text.DateFormatSymbols;
monthString = new DateFormatSymbols().getMonths()[month-1];

Alternatively, you could use SimpleDateFormat:

import java.text.SimpleDateFormat;
System.out.println(new SimpleDateFormat("MMMM").format(date));

(You'll have to put a date with your month in a Date object to use the second option).

I was facing same problem below is the solution that worked for me

First Go to Android SDK Manager then

select Tools then,

select Options

then check the box "Force https://... sources to be fetched using http://..."

hope it will help you also.

None of the other solutions worked for me. In my app, I'm adding the date range elements to the document using jquery and then applying datepicker to them. So none of the event solutions worked for some reason.

This is what finally worked:

$(document).on('changeDate',"#elementid", function(){
    alert('event fired');
});

Hope this helps someone because this set me back a bit.

Fetch the remote branch from the origin first.

git fetch origin remote_branch_name

Merge the remote branch to the local branch

git merge origin/remote_branch_name

You can do some Javascript in the form's submit event. That's all you can do though, there's no way to get browsers to do this by themselves. It also means your form will break for users without Javascript. Better is to know on the server which checkboxes there are, so you can deduce that those absent from the posted form values ($_POST in PHP) are unchecked.

You can try this:

ls -d $PWD/*

Non-numpy functions like math.abs() or math.log10() don't play nicely with numpy arrays. Just replace the line raising an error with:

m = np.log10(np.abs(x))

Apart from that the np.polyfit() call will not work because it is missing a parameter (and you are not assigning the result for further use anyway).

You can use also

select * from tablename where column1 ='a' and column2!='b';

predQuery[preId]=='undefined'

You're testing against the string 'undefined'; you've confused this test with the typeof test which would return a string. You probably mean to be testing against the special value undefined:

predQuery[preId]===undefined

Note the strict-equality operator to avoid the generally-unwanted match null==undefined.

However there are two ways you can get an undefined value: either preId isn't a member of predQuery, or it is a member but has a value set to the special undefined value. Often, you only want to check whether it's present or not; in that case the in operator is more appropriate:

!(preId in predQuery)

I'm used "for" operator.

        message.From = new System.Net.Mail.MailAddress(c);// Set sender .In this case the same as the username
        message.Subject = label3.Text; // Set subject
        message.Body = richTextBox1.Text; // Set body of message
        client.Send(message); // Send the message
        message = null; // Clean up

If you're trying to do the 'gapless' thing, I strongly advise you to

The SQL you posted in your question is one way to do it. Most things in SQL have more than one way to do it.

If you are planning on running this on a PROD DB, it is best to create a snapshot or mirror of it first and test it out. Verify the data ends up as you expect for a couple records. And if you are satisfied, run it on the real DB.

Python variables are scoped to the innermost function, class, or module in which they're assigned. Control blocks like if and while blocks don't count, so a variable assigned inside an if is still scoped to a function, class, or module.

(Implicit functions defined by a generator expression or list/set/dict comprehension do count, as do lambda expressions. You can't stuff an assignment statement into any of those, but lambda parameters and for clause targets are implicit assignment.)

Facebook Developer Wiki (unofficial) contain not only list of FQL error codes but others too it's somehow updated but not contain full list of possible error codes.

There is no any official or updated (I mean really updated) list of error codes returned by Graph API. Every list that can be found online is outdated and not help that much...

There is official list describing some of API Errors and basic recovery tactics. Also there is couple of offcial lists for specific codes:

• OAuth Errors
• Credits Error codes - Facebook Credits is unsupported from Sep 2013

MSDN Reference

Short answer:

use a non-blocking recv(), or a blocking recv() / select() with a very short timeout.

Long answer:

The way to handle socket connections is to read or write as you need to, and be prepared to handle connection errors.

TCP distinguishes between 3 forms of "dropping" a connection: timeout, reset, close.

Of these, the timeout can not really be detected, TCP might only tell you the time has not expired yet. But even if it told you that, the time might still expire right after.

Also remember that using shutdown() either you or your peer (the other end of the connection) may close only the incoming byte stream, and keep the outgoing byte stream running, or close the outgoing stream and keep the incoming one running.

So strictly speaking, you want to check if the read stream is closed, or if the write stream is closed, or if both are closed.

Even if the connection was "dropped", you should still be able to read any data that is still in the network buffer. Only after the buffer is empty will you receive a disconnect from recv().

Checking if the connection was dropped is like asking "what will I receive after reading all data that is currently buffered ?" To find that out, you just have to read all data that is currently bufferred.

I can see how "reading all buffered data", to get to the end of it, might be a problem for some people, that still think of recv() as a blocking function. With a blocking recv(), "checking" for a read when the buffer is already empty will block, which defeats the purpose of "checking".

In my opinion any function that is documented to potentially block the entire process indefinitely is a design flaw, but I guess it is still there for historical reasons, from when using a socket just like a regular file descriptor was a cool idea.

What you can do is:

• set the socket to non-blocking mode, but than you get a system-depended error to indicate the receive buffer is empty, or the send buffer is full
• stick to blocking mode but set a very short socket timeout. This will allow you to "ping" or "check" the socket with recv(), pretty much what you want to do
• use select() call or asyncore module with a very short timeout. Error reporting is still system-specific.

For the write part of the problem, keeping the read buffers empty pretty much covers it. You will discover a connection "dropped" after a non-blocking read attempt, and you may choose to stop sending anything after a read returns a closed channel.

I guess the only way to be sure your sent data has reached the other end (and is not still in the send buffer) is either:

• receive a proper response on the same socket for the exact message that you sent. Basically you are using the higher level protocol to provide confirmation.
• perform a successful shutdow() and close() on the socket

The python socket howto says send() will return 0 bytes written if channel is closed. You may use a non-blocking or a timeout socket.send() and if it returns 0 you can no longer send data on that socket. But if it returns non-zero, you have already sent something, good luck with that :)

Also here I have not considered OOB (out-of-band) socket data here as a means to approach your problem, but I think OOB was not what you meant.

You can only set the connection timeout on the connection string, the timeout for your query would normally be on the command timeout. (Assuming we are talking .net here, I can't really tell from your question).

However the command timeout has no effect when the command is executed against a context connection (a SqlConnection opened with "context connection=true" in the connection string).

The best solution is maybe to calculate the size of each database file, using the sys.sysfiles view, considering a size of 8 KB for each page, as follows:

USE [myDatabase]
GO

SELECT
    [size] * 8
    , [filename]
FROM sysfiles

The [field] column represents the size of the file, in pages (MSDN Reference to sysfiles).

You would see there will be at least two files (MDF and LDF): the sum of these files will give you the correct size of the entire database...

In TF1, the statement x.assign(1) does not actually assign the value 1 to x, but rather creates a tf.Operation that you have to explicitly run to update the variable.* A call to Operation.run() or Session.run() can be used to run the operation:

assign_op = x.assign(1)
sess.run(assign_op)  # or `assign_op.op.run()`
print(x.eval())
# ==> 1

(* In fact, it returns a tf.Tensor, corresponding to the updated value of the variable, to make it easier to chain assignments.)

However, in TF2 x.assign(1) will now assign the value eagerly:

x.assign(1)
print(x.numpy())
# ==> 1

$time = strtotime("2010.12.11");
$final = date("Y-m-d", strtotime("+1 month", $time));

// Finally you will have the date you're looking for.

Any chance your IIS is configured to require SSL on connections to your site/application?

this is my solution.

SELECT song_ID,songs.fullname, singers.fullname
FROM music JOIN songs ON songs.ID = music.song_ID  
JOIN singers ON singers.ID = music.singer_ID
GROUP BY songs.fullname

You must have the GROUP BY to get it to work.

Hope this help.

You may use Window#dispose() method to release all of the native screen resources, subcomponents, and all of its owned children.

The System.exit(0) will terminates the currently running Java Virtual Machine.

Take a look at my implementation. It's safe from null lists.

 IList<string> all= new List<string>();

 if (letterForm.SecretaryPhone!=null)// first list may be null
     all=all.Concat(letterForm.SecretaryPhone).ToList();

 if (letterForm.EmployeePhone != null)// second list may be null
     all= all.Concat(letterForm.EmployeePhone).ToList(); 

 if (letterForm.DepartmentManagerName != null) // this is not list (its just string variable) so wrap it inside list then concat it 
     all = all.Concat(new []{letterForm.DepartmentManagerPhone}).ToList();

None of the above answers worked for me using Hibernate 5.2.10, Jersey 2.25.1 and Jackson 2.8.9. I finally found the answer (sort of, they reference hibernate4module but it works for 5 too) here. None of the Json annotations worked at all with @Transient. Apparently Jackson2 is 'smart' enough to kindly ignore stuff marked with @Transient unless you explicitly tell it not to. The key was to add the hibernate5 module (which I was using to deal with other Hibernate annotations) and disable the USE_TRANSIENT_ANNOTATION feature in my Jersey Application:

ObjectMapper jacksonObjectMapper = new ObjectMapper();
Hibernate5Module jacksonHibernateModule = new Hibernate5Module();
jacksonHibernateModule.disable(Hibernate5Module.Feature.USE_TRANSIENT_ANNOTATION);
jacksonObjectMapper.registerModule(jacksonHibernateModule);  

Here is the dependency for the Hibernate5Module:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-hibernate5</artifactId>
    <version>2.8.9</version>
</dependency>

It's probably worth noting that IE won't cache css files called by other css files using the @import method. So, for example, if your html page links to "master.css" which pulls in "reset.css" via @import, then reset.css will not be cached by IE.

Found this thread when I couldn't load a json-file with ES6 TypeScript 2.6. I kept getting this error:

TS2307 (TS) Cannot find module 'json-loader!./suburbs.json'

To get it working I had to declare the module first. I hope this will save a few hours for someone.

declare module "json-loader!*" {
  let json: any;
  export default json;
}

...

import suburbs from 'json-loader!./suburbs.json';

If I tried to omit loader from json-loader I got the following error from webpack:

BREAKING CHANGE: It's no longer allowed to omit the '-loader' suffix when using loaders. You need to specify 'json-loader' instead of 'json', see https://webpack.js.org/guides/migrating/#automatic-loader-module-name-extension-removed

You can also achieve other way using button tag

According new html5 attribute you also can add a form attribute like

<form id="formId">
    <input type="text" name="fname">
</form>

<button id="myButton" form='#formId'>My Awesome Button</button>

So the button will be attached to the form.

This should work with the validate() plugin of jQuery like :

var validator = $( "#formId" ).validate();
validator.element( "#myButton" );

It's working too with input tag

Just to top this up to the new Java 8 API:

DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("MMMM dd, yyyy").toFormatter();
TemporalAccessor ta = formatter.parse("June 27, 2007");
Instant instant = LocalDate.from(ta).atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date d = Date.from(instant);
assertThat(d.getYear(), is(107));
assertThat(d.getMonth(), is(5));

A bit more verbose but you also see that the methods of Date used are deprecated ;-) Time to move on.

Very simple just do this:

<button ng-click="hideShow=(hideShow ? false : true)">Toggle</button>

<div ng-if="hideShow">hide and show content ...</div>

Try Case

SELECT   stock.name,
      CASE 
         WHEN stock.quantity <20 THEN 'Buy urgent'
         ELSE 'There is enough'
      END
FROM stock

These are mostly equivalent, but import * has some restrictions that import ... = require doesn't.

import * as creates an identifier that is a module object, emphasis on object. According to the ES6 spec, this object is never callable or newable - it only has properties. If you're trying to import a function or class, you should use

import express = require('express');

or (depending on your module loader)

import express from 'express';

Attempting to use import * as express and then invoking express() is always illegal according to the ES6 spec. In some runtime+transpilation environments this might happen to work anyway, but it might break at any point in the future without warning, which will make you sad.

You can use LINQ

char c = mystring.FirstOrDefault()

It will be equal to '\0' if the string is empty.

This site has two pretty simple solutions - just check the code, I provided the descriptions in case you wanted them - saves you some clicks.

http://www.richardlord.net/blog/dates-in-php-and-mysql

1.One common solution is to store the dates in DATETIME fields and use PHPs date() and strtotime() functions to convert between PHP timestamps and MySQL DATETIMEs. The methods would be used as follows -

$mysqldate = date( 'Y-m-d H:i:s', $phpdate );
$phpdate = strtotime( $mysqldate );

2.Our second option is to let MySQL do the work. MySQL has functions we can use to convert the data at the point where we access the database. UNIX_TIMESTAMP will convert from DATETIME to PHP timestamp and FROM_UNIXTIME will convert from PHP timestamp to DATETIME. The methods are used within the SQL query. So we insert and update dates using queries like this -

$query = "UPDATE table SET
    datetimefield = FROM_UNIXTIME($phpdate)
    WHERE...";
$query = "SELECT UNIX_TIMESTAMP(datetimefield)
    FROM table WHERE...";

Although John Leidegren keeps shooting down the idea, Brian is correct. I've just got it working in Visual Studio.

To be clear a WPF application does not create a Console window by default.

You have to create a WPF Application and then change the OutputType to "Console Application". When you run the project you will see a console window with your WPF window in front of it.

It doesn't look very pretty, but I found it helpful as I wanted my app to be run from the command line with feedback in there, and then for certain command options I would display the WPF window.

In case you also want to include your real name in the from-field, you can use the following format

mailx -r "[email protected] (My Name)" -s "My Subject" ...

If you happen to have non-ASCII characters in you name, like My AEÆoeøaaå (Æ= C3 86, ø= C3 B8, å= C3 A5), you have to encode them like this:

mailx -r "[email protected] (My =?utf-8?Q?AE=C3=86oe=C3=B8aa=C3=A5?=)" -s "My Subject" ...

Hope this can save someone an hour of hard work/research!

I might approach it like so (CSS and HTML):

  margin: 0px;_x000D_

  height: 75px;_x000D_
  margin-left: 400px; /* Flush links (with a 25px "padding") right of logo */_x000D_
}

Make use of Jackson JSON Parser

ObjectMapper mapper = new ObjectMapper();
Map<String,Object> map = mapper.readValue(inputStreamObject,Map.class);

If you want specifically a JSONObject then you can convert the map

JSONObject json = new JSONObject(map);

Refer this for the usage of JSONObject constructor http://stleary.github.io/JSON-java/index.html

Looks like you need the package from the installation media if you're you're offline (located at D:\sources\sxs) You could copy this to each machine that you require .NET 3.5 on (so technically you only need the installation media once to get the package) and get each machine to run the command:

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

There's a guide on MSDN.

Just wanted to complete the thread. To be very clear this does not works in IE9, however we can do it by little css trick.

<div class="customselect">
    <select>
    <option>2000</option>
    <option>2001</option>
    <option>2002</option>
    </select>
</div>

.customselect {
    width: 80px;
    overflow: hidden;
   border:1px solid;
}

.customselect select {
   width: 100px;
   border:none;
  -moz-appearance: none;
   -webkit-appearance: none;
   appearance: none;
}

Or you may do the following

$(this).animate({color:'black'},1000);

But you need to download the color plugin from here.

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path. As mention below exePath mean folder where exe placed along with it's references files.

Exe application creating any temporaray file so it will create in folder mention in processBuilder.directory(...)

**

ProcessBuilder processBuilder = new ProcessBuilder(arguments);
processBuilder.redirectOutput(Redirect.PIPE);
processBuilder.directory(new File(exePath));
process = processBuilder.start();
int waitFlag = process.waitFor();// Wait to finish application execution.
if (waitFlag == 0) {
...
 int returnVal = process.exitValue();
}

DECLARE @intFlag INT
SET @intFlag = 1
WHILE (@intFlag <=5) 
BEGIN
    PRINT @intFlag
    SET @intFlag = @intFlag + 1
END

All files must be delete from the directory before it is deleted.

There are third party libraries that have a lot of common utilities, including ones that does that for you:

• Apache commons-lang FileUtils.forceDelete(..)
• guava Files.deleteRecursively(..)

From this news group posting by Mark Zbikowski himself:

The differences between .CMD and .BAT as far as CMD.EXE is concerned are: With extensions enabled, PATH/APPEND/PROMPT/SET/ASSOC in .CMD files will set ERRORLEVEL regardless of error. .BAT sets ERRORLEVEL only on errors.

In other words, if ERRORLEVEL is set to non-0 and then you run one of those commands, the resulting ERRORLEVEL will be:

• left alone at its non-0 value in a .bat file
• reset to 0 in a .cmd file.

Not on the freehackers list is gui2exe which can be used to build standalone Windows executables, Linux applications and Mac OS application bundles and plugins starting from Python scripts.

Before the scanf put fflush(stdin); to clear buffer.

Right click on your Subversion working directory folder, and select TortoiseSVN->Clean Up from the Context Menu. This will recurse it's way through your working directory and cleanup any incomplete actions, remove the local locks (which is different from using Subversion locking of a file in the repository which lets everyone know about the lock).

If that doesn't work, see if you can find the names of the files that were changed, but not yet committed, save them, and redo the checkout.

If you want to keep it simple, this should suffice:

function parseIsoDatetime(dtstr) {
    var dt = dtstr.split(/[: T-]/).map(parseFloat);
    return new Date(dt[0], dt[1] - 1, dt[2], dt[3] || 0, dt[4] || 0, dt[5] || 0, 0);
}

note parseFloat is must, parseInt doesn't always work. Map requires IE9 or later.

Works for formats:

ALTER TABLE myTable MODIFY myColumn {DataType} NULL

The largest integer that can be represented in IEEE 754 double (64-bit) is the same as the largest value that the type can represent, since that value is itself an integer.

This is represented as 0x7FEFFFFFFFFFFFFF, which is made up of:

• The sign bit 0 (positive) rather than 1 (negative)
• The maximum exponent 0x7FE (2046 which represents 1023 after the bias is subtracted) rather than 0x7FF (2047 which indicates a NaN or infinity).
• The maximum mantissa 0xFFFFFFFFFFFFF which is 52 bits all 1.

In binary, the value is the implicit 1 followed by another 52 ones from the mantissa, then 971 zeros (1023 - 52 = 971) from the exponent.

The exact decimal value is:

179769313486231570814527423731704356798070567525844996598917476803157260780028538760589558632766878171540458953514382464234321326889464182768467546703537516986049910576551282076245490090389328944075868508455133942304583236903222948165808559332123348274797826204144723168738177180919299881250404026184124858368

This is approximately 1.8 x 10³⁰⁸.

I had the problem due to an extra space in the name of the linked server. "SERVER1, 1234" instead of "SERVER1,1234"

The BOM is generated by, say, File.WriteAllText() or StreamWriter when you don't specify an Encoding. The default is to use the UTF8 encoding and generate a BOM. You can tell the java compiler about this with its -encoding command line option.

The path of least resistance is to avoid generating the BOM. Do so by specifying System.Text.Encoding.Default, that will write the file with the characters in the default code page of your operating system and doesn't write a BOM. Use the File.WriteAllText(String, String, Encoding) overload or the StreamWriter(String, Boolean, Encoding) constructor.

Just make sure that the file you create doesn't get compiled by a machine in another corner of the world. It will produce mojibake.

I will try to answer the question of "why". Imagine a situation where you have a huge database with a lot of columns in a table, and your project/system uses tools to generate entities from database. (Hibernate has those, etc...) Now, suppose that by your business logic you need a particular field NOT to be persisted. You have to "configure" your entity in a particular way. While Transient keyword works on an object - as it behaves within a java language, the @Transient only designed to answer the tasks that pertains only to persistence tasks.

I usually do it this way whenever I need a date/time string:

set dt=%DATE:~6,4%_%DATE:~3,2%_%DATE:~0,2%__%TIME:~0,2%_%TIME:~3,2%_%TIME:~6,2%
set dt=%dt: =0%

This is for the German date/time format (dd.mm.yyyy hh:mm:ss). Basically I concatenate the substrings and finally replace all spaces with zeros.

Short explanation of how substrings work:

%VARIABLE:~num_chars_to_skip,num_chars_to_keep%

So to get just the year from a date like "29.03.2018" use:

%DATE:~6,4%
       ^-----skip 6 characters
         ^---keep 4 characters 

I had a similar problem when I added ActionBarSherlock as a library in my project. Eclipse ADT v21.0 pre-created dex files supposedly for faster building of the project. These dex files were the same as some of the jar files in my lib folder. So just keep one and delete the other. I deleted the ones in the lib folder as the dexed files were generating automatically.

You should use the excellent OpenCSV for reading and writing CSV files. To adapt your example to use the library it would look like this:

public class ParseCSV {
  public static void main(String[] args) {
    try {
      //csv file containing data
      String strFile = "C:/Users/rsaluja/CMS_Evaluation/Drupal_12_08_27.csv";
      CSVReader reader = new CSVReader(new FileReader(strFile));
      String [] nextLine;
      int lineNumber = 0;
      while ((nextLine = reader.readNext()) != null) {
        lineNumber++;
        System.out.println("Line # " + lineNumber);

        // nextLine[] is an array of values from the line
        System.out.println(nextLine[4] + "etc...");
      }
    }
  }
}

Open .edmx file any text editor change the Schema="your required schema" and also open the app.config/web.config, change the user id and password from the connection string. you are done.

If it's an NSMutableString (which I would recommend since you're changing it dynamically), you can use:

[myString deleteCharactersInRange:NSMakeRange([myRequestString length]-1, 1)];

Just my 2 cents as stated in the answer above : The copy() method shouldn't be used as-is for copying files without a slight adjustment:

function copy(callback) {
    var readStream = fs.createReadStream(oldPath);
    var writeStream = fs.createWriteStream(newPath);

    readStream.on('error', callback);
    writeStream.on('error', callback);

    // Do not callback() upon "close" event on the readStream
    // readStream.on('close', function () {
    // Do instead upon "close" on the writeStream
    writeStream.on('close', function () {
        callback();
    });

    readStream.pipe(writeStream);
}

The copy function wrapped in a Promise:

function copy(oldPath, newPath) {
  return new Promise((resolve, reject) => {
    const readStream = fs.createReadStream(oldPath);
    const writeStream = fs.createWriteStream(newPath);

    readStream.on('error', err => reject(err));
    writeStream.on('error', err => reject(err));

    writeStream.on('close', function() {
      resolve();
    });

    readStream.pipe(writeStream);
  })

However, keep in mind that the filesystem might crash if the target folder doesn't exist.

In Python, a method is a function that is available for a given object because of the object's type.

For example, if you create my_list = [1, 2, 3], the append method can be applied to my_list because it's a Python list: my_list.append(4). All lists have an append method simply because they are lists.

As another example, if you create my_string = 'some lowercase text', the upper method can be applied to my_string simply because it's a Python string: my_string.upper().

Lists don't have an upper method, and strings don't have an append method. Why? Because methods only exist for a particular object if they have been explicitly defined for that type of object, and Python's developers have (so far) decided that those particular methods are not needed for those particular objects.

To call a method, the format is object_name.method_name(), and any arguments to the method are listed within the parentheses. The method implicitly acts on the object being named, and thus some methods don't have any stated arguments since the object itself is the only necessary argument. For example, my_string.upper() doesn't have any listed arguments because the only required argument is the object itself, my_string.

One common point of confusion regards the following:

import math
math.sqrt(81)

Is sqrt a method of the math object? No. This is how you call the sqrt function from the math module. The format being used is module_name.function_name(), instead of object_name.method_name(). In general, the only way to distinguish between the two formats (visually) is to look in the rest of the code and see if the part before the period (math, my_list, my_string) is defined as an object or a module.

p_value is among f statistics. if you want to get the value, simply use this few lines of code:

import statsmodels.api as sm
from scipy import stats

diabetes = datasets.load_diabetes()
X = diabetes.data
y = diabetes.target

X2 = sm.add_constant(X)
est = sm.OLS(y, X2)
print(est.fit().f_pvalue)

Use the PercentRelativeLayout or PercentFrameLayout from the Percent Supoort Library

<android.support.percent.PercentFrameLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
     <TextView
          android:layout_width="match_parent"
          app:layout_heightPercent="68%"/>
     <Gallery 
          android:id="@+id/gallery"
          android:layout_width="match_parent"
          app:layout_heightPercent="16%"/>
     <TextView
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_width="match_parent"/>
</android.support.percent.PercentFrameLayout>

Definitely not the ideal solution, but it's easier for me to understand if I convert the list into tuples and then sort it.

mylist = [[1,2,3,4],[4,5,6,7]]
mylist2 = []
for thing in mylist:
    thing = tuple(thing)
    mylist2.append(thing)
set(mylist2)

The current answers are fine and should work ok, but what's wrong with the more simple, more obvious, and more maintainable:

IF @flag = 1
    UPDATE table_name SET column_A = column_A + @new_value WHERE ID = @ID;
ELSE
    UPDATE table_name SET column_B = column_B + @new_value WHERE ID = @ID;

This is much easier to read albeit this is a very simple query.

Here's a working example courtesy of @snyder: SqlFiddle.

Others have noted the correct answer, but have not clearly explained the all-important reason:

• why do we need this?

What do < and > stand for?

• < stands for the < sign. Just remember: lt == less than
• > stands for the > Just remember: gt == greater than

Why can’t we simply use the < and > characters in HTML?

• This is because the > and < characters are ‘reserved’ characters in HTML.
• HTML is a mark up language: The < and > are used to denote the starting and ending of different elements: e.g. <h1> and not for the displaying of the greater than or less than symbols. But what if you wanted to actually display those symbols? You would simply use < and > and the browser will know exactly how to display it.

Getting all the subsets with recursion. Crazy-ass one-liner

from typing import List

def subsets(xs: list) -> List[list]:
    return subsets(xs[1:]) + [x + [xs[0]] for x in subsets(xs[1:])] if xs else [[]]

Based on a Haskell solution

subsets :: [a] -> [[a]]
subsets [] = [[]]
subsets (x:xs) = map (x:) (subsets xs) ++ subsets xs

the easy way to find either posted value is integer and float so this will help you

$postedValue = $this->input->post('value');
if(is_numeric( $postedValue ) && floor( $postedValue ))
{
    echo 'success';
}
else
{
   echo 'unsuccess';
}

if you give 10 or 10.5 or 10.0 the result will be success if you define any character or specail character without dot it will give unsuccess

Use <em> if you need some words/characters in italic in content without other styles. It also helps make content semantic.

text-style is better suited for multiple styles and no semantic need.

use simple code for remove default browser style for outline

input { outline: none; }

In about:config add content.cors.disable (empty string).

There are many ways it can be achieved. The tool you use mostly depends on your own preference or experience.

Using tr command:

tr '\n' ',' < somefile

Using awk:

awk -F'\n' '{if(NR == 1) {printf $0} else {printf ","$0}}' somefile

see ?tail and ?head for some convenient functions:

> x <- 1:10
> tail(x,5)
[1]  6  7  8  9 10

For the argument's sake : everything but the last five elements would be :

> head(x,n=-5)
[1] 1 2 3 4 5

As @Martin Morgan says in the comments, there are two other possibilities which are faster than the tail solution, in case you have to carry this out a million times on a vector of 100 million values. For readibility, I'd go with tail.

test                                        elapsed    relative 
tail(x, 5)                                    38.70     5.724852     
x[length(x) - (4:0)]                           6.76     1.000000     
x[seq.int(to = length(x), length.out = 5)]     7.53     1.113905     

benchmarking code :

require(rbenchmark)
x <- 1:1e8
do.call(
  benchmark,
  c(list(
    expression(tail(x,5)),
    expression(x[seq.int(to=length(x), length.out=5)]),
    expression(x[length(x)-(4:0)])
  ),  replications=1e6)
)

substring(field, 1,3) will work on your examples.

select substring(field, 1,3) from table

Also, if the alphabetic part is of variable length, you can do this to extract the alphabetic part:

select substring(field, 1, PATINDEX('%[1234567890]%', field) -1) 
from table
where PATINDEX('%[1234567890]%', field) > 0

I would suggest using the new mixins approach described there: https://blogs.msdn.microsoft.com/typescript/2017/02/22/announcing-typescript-2-2/

This approach is better, than the "applyMixins" approach described by Fenton, because the autocompiler would help you and show all the methods / properties from the both base and 2nd inheritance classes.

This approach might be checked on the TS Playground site.

Here is the implementation:

class MainClass {
    testMainClass() {
        alert("testMainClass");
    }
}

const addSecondInheritance = (BaseClass: { new(...args) }) => {
    return class extends BaseClass {
        testSecondInheritance() {
            alert("testSecondInheritance");
        }
    }
}

// Prepare the new class, which "inherits" 2 classes (MainClass and the cass declared in the addSecondInheritance method)
const SecondInheritanceClass = addSecondInheritance(MainClass);
// Create object from the new prepared class
const secondInheritanceObj = new SecondInheritanceClass();
secondInheritanceObj.testMainClass();
secondInheritanceObj.testSecondInheritance();

Most of bootstrap datepickers as I write this answer are rather buggy when included in Bootstrap 4. In my view the least code adding solution is a jQuery plugin. I used this one https://plugins.jquery.com/datetimepicker/ - you can see its usage here: https://xdsoft.net/jqplugins/datetimepicker/ It sure is not as smooth as the whole BS interface, but it only requires its css and js files along with jQuery which is already included in bootstrap.

This is probably the most correct, direct replacement: insertAdjacentHTML.

The user @manoj has provided the correct answer to the question. From Kibana host, a request to http://localhost:9200/ will not be answered, unless ElasticSearch is also running on the same node. Kibana listens on port 5601 not 9200.

In most cases, except for DEV, ElasticSearch will not be on the same node as Kibana, for a number of reasons. Therefore, to get information about your ElasticSearch from Kibana, you should select the "Dev Tools" tab on the left and in the console issue the command: GET /

I came here searching for this answer as well, and here is what I found works the best for me: Note I am using Ubuntu 16.x.x

1. Access mysql using:

2. At the mysql prompt, enter:

Hope this helps.

You are using an immutable list. The operations on the List return a new List. The old List remains unchanged. This can be very useful if another class / method holds a reference to the original collection and is relying on it remaining unchanged. You can either use different named vals as in

val myList1 = 1.0 :: 5.5 :: Nil 
val myList2 = 2.2 :: 3.7 :: mylist1

or use a var as in

var myList = 1.0 :: 5.5 :: Nil 
myList :::= List(2.2, 3.7)

This is equivalent syntax for:

myList = myList.:::(List(2.2, 3.7))

Or you could use one of the mutable collections such as

val myList = scala.collection.mutable.MutableList(1.0, 5.5)
myList.++=(List(2.2, 3.7))

Not to be confused with the following that does not modify the original mutable List, but returns a new value:

myList.++:(List(2.2, 3.7))

However you should only use mutable collections in performance critical code. Immutable collections are much easier to reason about and use. One big advantage is that immutable List and scala.collection.immutable.Vector are Covariant. Don't worry if that doesn't mean anything to you yet. The advantage of it is you can use it without fully understanding it. Hence the collection you were using by default is actually scala.collection.immutable.List its just imported for you automatically.

I tend to use List as my default collection. From 2.12.6 Seq defaults to immutable Seq prior to this it defaulted to immutable.

jminix is an embedded web based JMX console. Not sure if it's maintained any longer, but still.

I got this error too even I ran cmd as an Administrator.

The root cause is: The file is from VCS(subversion, perforce, etc.), and when I checked the properties of this file, its' Attributes is Read-only.

So the solution is:

• (1) disable the 'Read-only' Attribute;
• (2) check out from VCS, let the file under the status of read&write.

using System.Security.Cryptography;

public static byte[] GetHash(string inputString)
{
    using (HashAlgorithm algorithm = SHA256.Create())
        return algorithm.ComputeHash(Encoding.UTF8.GetBytes(inputString));
}

public static string GetHashString(string inputString)
{
    StringBuilder sb = new StringBuilder();
    foreach (byte b in GetHash(inputString))
        sb.Append(b.ToString("X2"));

    return sb.ToString();
}

Additional Notes

• Since MD5 and SHA1 are obsolete and insecure algorithms, this solution uses SHA256. Alternatively, you can use BCrypt or Scrypt as pointed out in comments.
• Also, consider "salting" your hashes and use proven cryptographic algorithms, as pointed out in comments.

For VB.NET developers Use this generic sub to mark the child state, easy to use

Notes:

• PromatCon: the entity object
• amList: is the child list that you want to add or modify
• rList: is the child list that you want to remove

updatechild(objCas.ECC_Decision, PromatCon.ECC_Decision.Where(Function(c) c.rid = objCas.rid And Not objCas.ECC_Decision.Select(Function(x) x.dcid).Contains(c.dcid)).toList)

Sub updatechild(Of Ety)(amList As ICollection(Of Ety), rList As ICollection(Of Ety))
        If amList IsNot Nothing Then
            For Each obj In amList
                Dim x = PromatCon.Entry(obj).GetDatabaseValues()
                If x Is Nothing Then
                    PromatCon.Entry(obj).State = EntityState.Added
                Else
                    PromatCon.Entry(obj).State = EntityState.Modified
                End If
            Next
        End If

        If rList IsNot Nothing Then
            For Each obj In rList.ToList
                PromatCon.Entry(obj).State = EntityState.Deleted
            Next
        End If
End Sub

PromatCon.SaveChanges()

You can use

System.getProperty("line.separator");

to get the line separator

The following would disable the selection of all classes 'item' in all common browsers (IE, Chrome, Mozilla, Opera and Safari):

$(".item")
        .attr('unselectable', 'on')
        .css({
            'user-select': 'none',
            'MozUserSelect': 'none'
        })
        .on('selectstart', false)
        .on('mousedown', false);

You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.

The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)

For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).

If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.

So in your case, you should try:

declare @a datetime
declare @b datetime 

set @a = '2012-04-06T12:23:45'   -- 6th of April, 2012
set @b = '2012-08-06T21:10:12'   -- 6th of August, 2012

exec LogProcedure 'AccountLog', N'test', @a, @b

Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.

So change this line here to this:

IF @DateFirst <> '' and @DateLast <> ''
   SET @FinalSQL  = @FinalSQL + '  OR CONVERT(Date, DateLog) >= ''' + 
                    CONVERT(VARCHAR(50), @DateFirst, 126) +   -- convert @DateFirst to string for concatenation!
                    ''' AND CONVERT(Date, DateLog) <=''' +  -- you need closing quotes after @DateFirst!
                    CONVERT(VARCHAR(50), @DateLast, 126) + ''''      -- convert @DateLast to string and also: closing tags after that missing!

With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.

Which version of SQL Server?

For SQL Server 2005 and later, you can obtain the SQL script used to create the view like this:

select definition
from sys.objects     o
join sys.sql_modules m on m.object_id = o.object_id
where o.object_id = object_id( 'dbo.MyView')
  and o.type      = 'V'

This returns a single row containing the script used to create/alter the view.

Other columns in the table tell about about options in place at the time the view was compiled.

Caveats

• If the view was last modified with ALTER VIEW, then the script will be an ALTER VIEW statement rather than a CREATE VIEW statement.

• The script reflects the name as it was created. The only time it gets updated is if you execute ALTER VIEW, or drop and recreate the view with CREATE VIEW. If the view has been renamed (e.g., via sp_rename) or ownership has been transferred to a different schema, the script you get back will reflect the original CREATE/ALTER VIEW statement: it will not reflect the objects current name.

• Some tools truncate the output. For example, the MS-SQL command line tool sqlcmd.exe truncates the data at 255 chars. You can pass the parameter -y N to get the result with N chars.

I like prettyPhoto

prettyPhoto is a jQuery lightbox clone. Not only does it support images, it also support for videos, flash, YouTube, iframes and ajax. It’s a full blown media lightbox

The answers above are very good I'm sure. But for dim-wits, like me, I recommend Snagit 10. You can give an image a border in any width, style, and color before inserting it into your webpage. They do a full working program on 30 day trial.

When a assembly' s AssemblyVersion is changed, If it has strong name, the referencing assemblies need to be recompiled, otherwise the assembly does not load! If it does not have strong name, if not explicitly added to project file, it will not be copied to output directory when build so you may miss depending assemblies, especially after cleaning the output directory.

Convert the date from the UTC calendar to one with the appropriate local NSTimeZone.
