In the Windows command prompt you can disable tab completion, by launching it thusly:

cmd.exe /f:off

Then the tab character will be echoed to the screen and work as you expect. Or you can disable the tab completion character, or modify what character is used for tab completion by modifying the registry.

The cmd.exe help page explains it:

You can enable or disable file name completion for a particular invocation of CMD.EXE with the /F:ON or /F:OFF switch. You can enable or disable completion for all invocations of CMD.EXE on a machine and/or user logon session by setting either or both of the following REG_DWORD values in the registry using REGEDIT.EXE:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar

    and/or

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar

with the hex value of a control character to use for a particular function (e.g. 0x4 is Ctrl-D and 0x6 is Ctrl-F). The user specific settings take precedence over the machine settings. The command line switches take precedence over the registry settings.

If completion is enabled with the /F:ON switch, the two control characters used are Ctrl-D for directory name completion and Ctrl-F for file name completion. To disable a particular completion character in the registry, use the value for space (0x20) as it is not a valid control character.

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

OUTPUT

<-ansi is an obsolete switch that requests the compiler to compile according to the 30-year-old obsolete revision of C standard, ISO/IEC 9899:1990, which is essentially a rebranding of the ANSI standard X3.159-1989 "Programming Language C. Why obsolete? Because after C90 was published by ISO, ISO has been in charge of the C standardization, and any technical corrigenda to C90 have been standardized by ISO. Thus it is more apt to use the -std=c90.

Without this switch, the recent GCC C compilers will conform to the C language standardized in ISO/IEC 9899:2011, or the newest 2018 revision.

Unfortunately there are some lazy compiler vendors that believe it is acceptable to stick to an older obsolete standard revision, for which the standardization document is not even available from standard bodies.

Using the switch helps ensuring that the code should compile in these obsolete compilers.

The -pedantic is an interesting one. In absence of -pedantic, even when a specific standard is requested, GCC will still allow some extensions that are not acceptable in the C standard. Consider for example the program

struct test {
    int zero_size_array[0];
};

The C11 draft n1570 paragraph 6.7.6.2p1 says:

In addition to optional type qualifiers and the keyword static, the [ and ] may delimit an expression or *. If they delimit an expression (which specifies the size of an array), the expression shall have an integer type. If the expression is a constant expression, it shall have a value greater than zero.[...]

The C standard requires that the array length be greater than zero; and this paragraph is in the constraints; the standard says the following 5.1.1.3p1:

A conforming implementation shall produce at least one diagnostic message (identified in an implementation-defined manner) if a preprocessing translation unit or translation unit contains a violation of any syntax rule or constraint, even if the behavior is also explicitly specified as undefined or implementation-defined. Diagnostic messages need not be produced in other circumstances.9)

However, if you compile the program with gcc -c -std=c90 pedantic_test.c, no warning is produced.

-pedantic causes the compiler to actually comply to the C standard; so now it will produce a diagnostic message, as is required by the standard:

gcc -c -pedantic -std=c90 pedantic_test.c
pedantic_test.c:2:9: warning: ISO C forbids zero-size array ‘zero_size_array’ [-Wpedantic]
     int zero_size_array[0];
         ^~~~~~~~~~~~~~~

Thus for maximal portability, specifying the standard revision is not enough, you must also use -pedantic (or -pedantic-errors) to ensure that GCC actually does comply to the letter of the standard.

The last part of the question was about using -ansi with C++. ANSI never standardized the C++ language - only adopting it from ISO, so this makes about as much sense as saying "English as standardized by France". However GCC still seems to accept it for C++, as stupid as it sounds.

You may need to write a javascript for each button submit. Instead of defining action in form definition, set those values in javascript. Something like below.

function callButton1(form, yourServ)
{
form.action = yourServ;
form.submit();
});

@Patrick To sort more than one field consecutively try ComparatorChain

A ComparatorChain is a Comparator that wraps one or more Comparators in sequence. The ComparatorChain calls each Comparator in sequence until either 1) any single Comparator returns a non-zero result (and that result is then returned), or 2) the ComparatorChain is exhausted (and zero is returned). This type of sorting is very similar to multi-column sorting in SQL, and this class allows Java classes to emulate that kind of behaviour when sorting a List.

To further facilitate SQL-like sorting, the order of any single Comparator in the list can >be reversed.

Calling a method that adds new Comparators or changes the ascend/descend sort after compare(Object, Object) has been called will result in an UnsupportedOperationException. However, take care to not alter the underlying List of Comparators or the BitSet that defines the sort order.

Instances of ComparatorChain are not synchronized. The class is not thread-safe at construction time, but it is thread-safe to perform multiple comparisons after all the setup operations are complete.

This worked for me:

First, go to

cd /etc/nginx

and make the changes in nginx.conf and make the default port to listen from 80 to any of your choice 85 or something.

Then use this command to bind that port type for nginx to use it:

semanage port -a -t PORT_TYPE -p tcp 85

where PORT_TYPE is one of the following: http_cache_port_t, http_port_t, jboss_management_port_t, jboss_messaging_port_t, ntop_port_t, puppet_port_t.

Then run:

sudo systemctl start nginx; #sudo systemctl status nginx

[you should see active status]; #sudo systemctl enable nginx

Using HashMap it is walk in the park.

main(){
    String[] array ={"a","ab","a","abc","abc","a","ab","ab","a"};
    Map<String,Integer> hm = new HashMap();

    for(String x:array){

        if(!hm.containsKey(x)){
            hm.put(x,1);
        }else{
            hm.put(x, hm.get(x)+1);
        }
    }
    System.out.println(hm);
}

Another option is to use https://github.com/spulec/freezegun/

Install it:

pip install freezegun

And use it:

from freezegun import freeze_time

@freeze_time("2012-01-01")
def test_something():

    from datetime import datetime
    print(datetime.now()) #  2012-01-01 00:00:00

    from datetime import date
    print(date.today()) #  2012-01-01

It also affects other datetime calls in method calls from other modules:

other_module.py:

from datetime import datetime

def other_method():
    print(datetime.now())    

main.py:

from freezegun import freeze_time

@freeze_time("2012-01-01")
def test_something():

    import other_module
    other_module.other_method()

And finally:

$ python main.py
# 2012-01-01

You can use reversed() function. For example

x = "abcd"
for i in reversed(x):
        print(i, end="")
print("\n")
L = [1,2,3]
for i in reversed(L):
        print(i, end="")

prints dcba and 321

80% of the time, when folks say "daemon", they only want a server. Since the question is perfectly unclear on this point, it's hard to say what the possible domain of answers could be. Since a server is adequate, start there. If an actual "daemon" is actually needed (this is rare), read up on nohup as a way to daemonize a server.

Until such time as an actual daemon is actually required, just write a simple server.

Also look at the WSGI reference implementation.

Also look at the Simple HTTP Server.

"Are there any additional things that need to be considered? " Yes. About a million things. What protocol? How many requests? How long to service each request? How frequently will they arrive? Will you use a dedicated process? Threads? Subprocesses? Writing a daemon is a big job.

-(void)saveToUserDefaults:(NSString*)string_to_store keys:(NSString *)key_for_the_String

    if (standardUserDefaults) {
        [standardUserDefaults setObject:string_to_store forKey:key_for_the_String];
        [standardUserDefaults synchronize];
    }
}

And call it by:

[self saveToUserDefaults:@"string_to_store" : @"key_for_the_string"];

Retrieve the string by using:

NSString * stored_string = [[NSUserDefaults standardUserDefaults] stringforkey:key_for_the_String]

To remove the query string from the request URI, replace the query string with an empty string:

    $query = $_SERVER['QUERY_STRING'];
    if(!empty($query)) {
        $result = str_replace('?' . $query, '', $result);
    }
    return $result;
}

Ensure they are being called in the php.ini file

If the PDO is displayed in the list of currently installed php modules, you will want to check the php.ini file in the relevant folder to ensure they are being called. Somewhere in the php.ini file you should see the following:

extension=pdo.so
extension=pdo_sqlite.so
extension=pdo_mysql.so
extension=sqlite.so

If they are not present, simply add the lines above to the bottom of the php.ini file and save it.

onclick is basically an addEventListener that specifically performs a function when the element is clicked. So, useful when you have a button that does simple operations, like a calculator button. addEventlistener can be used for a multitude of things like performing an operation when DOM or all content is loaded, akin to window.onload but with more control.

Note, You can actually use more than one event with inline, or at least by using onclick by seperating each function with a semi-colon, like this....

I wouldn't write a function with inline, as you could potentially have problems later and it would be messy imo. Just use it to call functions already done in your script file.

Which one you use I suppose would depend on what you want. addEventListener for complex operations and onclick for simple. I've seen some projects not attach a specific one to elements and would instead implement a more global eventlistener that would determine if a tap was on a button and perform certain tasks depending on what was pressed. Imo that could potentially lead to problems I'd think, and albeit small, probably, a resource waste if that eventlistener had to handle each and every click

Ok I just noticed that my question was already answered in the question title.

To unstage files use

git reset HEAD /file/name

And to undo the changes to a file

git checkout -- /file/name

If you have a batch of files inside a folder you can undo the whole folder

git checkout -- /folder/name

Note that all these commands are already displayed when you git status

Here I created a dummy repo and listed all 3 possibilities

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       modified:   test
#
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   test2
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       test3

Here is what I use.

This is an old question, but one that is frequently visited and clear recommendations are now available from RFC 7303 which obsoletes RFC3023. In a nutshell (section 9.2):

The registration information for text/xml is in all respects the same
as that given for application/xml above (Section 9.1), except that
the "Type name" is "text".

Put this in your title popover constructor...

'<button class="btn btn-danger btn-xs pull-right"
onclick="$(this).parent().parent().parent().hide()"><span class="glyphicon
glyphicon-remove"></span></button>some text'

...to get a small red 'x' button on top-right corner

//$('[data-toggle=popover]').popover({title:that string here})

If you compile with optimizations enabled, then many variables will be removed; for example:

SomeType value = GetValue();
DoSomething(value);

here the local variable value would typically get removed, keeping the value on the stack instead - a bit like as if you had written:

DoSomething(GetValue());

Also, if a return value isn't used at all, then it will be dropped via "pop" (rather than stored in a local via "stloc", and again; the local will not exist).

Because of this, in such a build the debugger can't get the current value of value because it doesn't exist - it only exists for the brief instant between GetValue() and DoSomething(...).

So; if you want to debug... don't use a release build! or at least, disable optimizations while you debug.

You can use the auto_now and auto_now_add options for updated_at and created_at respectively.

class MyModel(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

Google deprecated the Android AsyncTask API in Android 11, even if you create a thread class outside the main activity, just by calling it in main you will get the same error, the calls must be inside a runnable thread, but if you need some asynchronous code to execute on the background or some on post afterwards here you can check out some alternatives for both Kotlin and Java

https://stackoverflow.com/questions/58767733/android-asynctask-api-deprecating-in-android-11-what-are-the-alternatives

the one that worked for me specifically was an answer by mayank1513 for a java 8 implementation of runnable thread found on the above link, code is as follows

new Thread(() -> {
        // do background stuff here
        runOnUiThread(()->{
            // OnPostExecute stuff here
        });
    }).start();

However you can define the thread first in some part of your code and start it somewhere else like this

thread definition

Thread thread = new Thread(() -> {
            // do background stuff here
            runOnUiThread(()->{
                // OnPostExecute stuff here
            });
        });

thread call

thread.start();

hope this saves someone the headache of seeing deprecated AsyncTask

To access the first and last elements, try.

var nodes = div.querySelectorAll('[move_id]');
var first = nodes[0];
var last = nodes[nodes.length- 1];

For robustness, add index checks.

Yes, the order of nodes is pre-order depth-first. DOM's document order is defined as,

There is an ordering, document order, defined on all the nodes in the document corresponding to the order in which the first character of the XML representation of each node occurs in the XML representation of the document after expansion of general entities. Thus, the document element node will be the first node. Element nodes occur before their children. Thus, document order orders element nodes in order of the occurrence of their start-tag in the XML (after expansion of entities). The attribute nodes of an element occur after the element and before its children. The relative order of attribute nodes is implementation-dependent.

you should use action instead of actionListener:

<h:commandLink id="close" action="#{bean.close}" value="Close" immediate="true" 
                                   />

and in close method you right something like:

public String close() {
   return "index?faces-redirect=true";
}

where index is one of your pages(index.xhtml)

Of course, all this staff should be written in our original page, not in the intermediate. And inside the close() method you can use the parameters to dynamically choose where to redirect.

You can use nested query for pagination as follow:

Paging from 4 Row to 8 Row where CustomerId is primary key.

SELECT Top 5 * FROM Customers
WHERE Country='Germany' AND CustomerId Not in (SELECT Top 3 CustomerID FROM Customers
WHERE Country='Germany' order by city) 
order by city;

psql -U postgres

Worked fine for me in case of db name: postgres & username: postgres. So you do not need to write sudo.

And in the case other db, you may try

psql -U yourdb postgres

As it is given in Postgres help:

psql [OPTION]... [DBNAME [USERNAME]]

The dir wrapper can wrap, any other step, and it all works inside a steps block, for example:

steps {
    sh "pwd"
    dir('your-sub-directory') {
      sh "pwd"
    }
    sh "pwd"
} 

timer.cancel();  //Terminates this timer,discarding any currently scheduled tasks.

timer.purge();   // Removes all cancelled tasks from this timer's task queue.

If you are on Windows and use anaconda this worked for me:

I tried a lot of other solutions which did not work (Environment PATH Variable changes ...)

The problem can be caused by DLLs in the Windows\System32 folder (e.g. libcrypto-1_1-x64.dll or libssl-1_1-x64.dll or others) placed there by other software.

The fix was installing openSSL from https://slproweb.com/products/Win32OpenSSL.html which replaces the dlls by more recent versions.

I faced with this error today, reason was; IIS user doesn't have permission to reach to the application folder. I gave the read permissions to the app root folder.

feof() is not very intuitive. In my very humble opinion, the FILE's end-of-file state should be set to true if any read operation results in the end of file being reached. Instead, you have to manually check if the end of file has been reached after each read operation. For example, something like this will work if reading from a text file using fgetc():

#include <stdio.h>

int main(int argc, char *argv[])
{
  FILE *in = fopen("testfile.txt", "r");

  while(1) {
    char c = fgetc(in);
    if (feof(in)) break;
    printf("%c", c);
  }

  fclose(in);
  return 0;
}

It would be great if something like this would work instead:

#include <stdio.h>

int main(int argc, char *argv[])
{
  FILE *in = fopen("testfile.txt", "r");

  while(!feof(in)) {
    printf("%c", fgetc(in));
  }

  fclose(in);
  return 0;
}

About the removal of componentWillReceiveProps: you should be able to handle its uses with a combination of getDerivedStateFromProps and componentDidUpdate, see the React blog post for example migrations. And yes, the object returned by getDerivedStateFromProps updates the state similarly to an object passed to setState.

In case you really need the old value of a prop, you can always cache it in your state with something like this:

state = {
  cachedSomeProp: null
  // ... rest of initial state
};

static getDerivedStateFromProps(nextProps, prevState) {
  // do things with nextProps.someProp and prevState.cachedSomeProp
  return {
    cachedSomeProp: nextProps.someProp,
    // ... other derived state properties
  };
}

Anything that doesn't affect the state can be put in componentDidUpdate, and there's even a getSnapshotBeforeUpdate for very low-level stuff.

UPDATE: To get a feel for the new (and old) lifecycle methods, the react-lifecycle-visualizer package may be helpful.

Try using additional condition in join:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 
INNER JOIN Table2
ON (Table1.Col1 = Table2.Col1 
    OR (Table1.Col1 IS NULL AND Table2.Col1 IS NULL)
   )

That image you linked to was for density curves, not histograms.

If you've been reading on ggplot then maybe the only thing you're missing is combining your two data frames into one long one.

So, let's start with something like what you have, two separate sets of data and combine them.

carrots <- data.frame(length = rnorm(100000, 6, 2))
cukes <- data.frame(length = rnorm(50000, 7, 2.5))

# Now, combine your two dataframes into one.  
# First make a new column in each that will be 
# a variable to identify where they came from later.
carrots$veg <- 'carrot'
cukes$veg <- 'cuke'

# and combine into your new data frame vegLengths
vegLengths <- rbind(carrots, cukes)

After that, which is unnecessary if your data is in long format already, you only need one line to make your plot.

ggplot(vegLengths, aes(length, fill = veg)) + geom_density(alpha = 0.2)

Now, if you really did want histograms the following will work. Note that you must change position from the default "stack" argument. You might miss that if you don't really have an idea of what your data should look like. A higher alpha looks better there. Also note that I made it density histograms. It's easy to remove the y = ..density.. to get it back to counts.

ggplot(vegLengths, aes(length, fill = veg)) + 
   geom_histogram(alpha = 0.5, aes(y = ..density..), position = 'identity')

This has been answered for the most part, but I will expand...

Step 1

My goal was to enable zoom at certain times, and disable it at others.

// enable pinch zoom
var $viewport = $('head meta[name="viewport"]');    
$viewport.attr('content', 'width=device-width, initial-scale=1, maximum-scale=4');

// ...later...

// disable pinch zoom
$viewport.attr('content', 'width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no');

Step 2

The viewport tag would update, but pinch zoom was still active!! I had to find a way to get the page to pick up the changes...

It's a hack solution, but toggling the opacity of body did the trick. I'm sure there are other ways to accomplish this, but here's what worked for me.

// after updating viewport tag, force the page to pick up changes           
document.body.style.opacity = .9999;
setTimeout(function(){
    document.body.style.opacity = 1;
}, 1);

Step 3

My problem was mostly solved at this point, but not quite. I needed to know the current zoom level of the page so I could resize some elements to fit on the page (think of map markers).

// check zoom level during user interaction, or on animation frame
var currentZoom = $document.width() / window.innerWidth;

I hope this helps somebody. I spent several hours banging my mouse before finding a solution.

It looks like the 'flush' answer will work for some, but not all cases. I needed not just to flush the values in the database, but to recreate the tables properly. I'm not using migrations yet (early days) so I really needed to drop all the tables.

Two ways I've found to drop all tables, both require something other than core django.

If you're on Heroku, drop all the tables with pg:reset:

heroku pg:reset DATABASE_URL
heroku run python manage.py syncdb

If you can install Django Extensions, it has a way to do a complete reset:

python ./manage.py reset_db --router=default

Apparently the solution differs between Ubuntu versions. Following worked for me on Ubuntu 13.10:

sudo apt-get install nodejs-legacy

HTH

Edit: Rule of thumb:

If you have installed nodejs but are missing the /usr/bin/node binary, then also install nodejs-legacy. This just creates the missing softlink.

According to my tests, Ubuntu 17.10 and above already have the compatibility-softlink /usr/bin/node in place after nodejs is installed, so nodejs-legacy is missing from these releases as it is no more needed.

You can delete all the documents from a collection in MongoDB, you can use the following:

db.users.remove({})

Alternatively, you could use the following method as well:

db.users.deleteMany({})

Follow the following MongoDB documentation, for further details.

To remove all documents from a collection, pass an empty filter document {} to either the db.collection.deleteMany() or the db.collection.remove() method.

      $('#myform').on('submit',function(event){
        // block form submit event
        event.preventDefault();

        // Do some stuff here
        ...

        // Continue the form submit
        event.currentTarget.submit();
  });

Well, more technically speaking, the difference between a static method and a virtual method is the way the are linked.

A traditional "static" method like in most non OO languages gets linked/wired "statically" to its implementation at compile time. That is, if you call method Y() in program A, and link your program A with library X that implements Y(), the address of X.Y() is hardcoded to A, and you can not change that.

In OO languages like JAVA, "virtual" methods are resolved "late", at run-time, and you need to provide an instance of a class. So in, program A, to call virtual method Y(), you need to provide an instance, B.Y() for example. At runtime, every time A calls B.Y() the implementation called will depend on the instance used, so B.Y() , C.Y() etc... could all potential provide different implementations of Y() at runtime.

Why will you ever need that? Because that way you can decouple your code from the dependencies. For example, say program A is doing "draw()". With a static language, thats it, but with OO you will do B.draw() and the actual drawing will depend on the type of object B, which, at runtime, can change to square a circle etc. That way your code can draw multiple things with no need to change, even if new types of B are provided AFTER the code was written. Nifty -

It reappears because your submit button reloads the page. The simplest way to prevent this behavior is to add a return false to the onclick like so:

<input type="submit" value="Remove DUMMY" onclick="removeDummy(); return false;" />

First lets take a scenario how 301 and 302 works

1. 301 --> Permanently moved

Imagine there is some resource like --> http://hashcodehub.com/user , now in future we are changing the resouce name to user- info --> now the url should be http://hashcodehub.com/user-info --> but the user is still trying to access the same URL --> http://hashcodehub.com/user --> here from the backend we can redirect the user to the new url and send the status code as 301 --> which is used for permanently moved.

Above I have explained how 301 Works

Lets understand how 302 will be used in real life

2. 302 --> Temporary redirection --> here the complete url does not need to be changed but for some reason we are redirecting to resource at different locations. Here in the location header field we will give the value of the new resource url browser will again make the request to the resource url in the response location header field.

3. 302 can be used just in case if there is something not appropriate content on our page .While we solve that issue we can redirect all our used to some temporary url and fix the issue.

4. It can also be used if there is some attach on the website and some pages requires restoration in that case also we can redirect the user to the different resource.

5. The redirect 302 serves, for example, to have several versions of a homepage in different languages.The main one can be in English; but if the visitors come from other countries then this system automatically redirects them to page in their language.

You can think of an iframe as an embedded browser window that you can put on an HTML page to show another URL inside it. This URL can be totally distinct from your web site/app.

You can put an iframe in any HTML page, so you could put one inside a contentplaceholder in a webform that has a Masterpage and it will appear with whatever URL you load into it (via Javascript, or C# if you turn your iframe into a server-side control (runat='server') on the final HTML page that your webform produces when requested.

And you can load a URL into your iframe that is a .aspx page.

But - iframes have nothing to do with the ASP.net mechanism. They are HTML elements that can be made to run server-side, but they are essentially 'dumb' and unmanaged/unconnected to the ASP.Net mechanisms - don't confuse a Contentplaceholder with an iframe.

Incidentally, the use of iframes is still contentious - do you really need to use one? Can you afford the negative trade-offs associated with them e.g. lack of navigation history ...?

button {
    background:transparent;
    border:none;
    outline:none;
    display:block;
    height:200px;
    width:200px;
    cursor:pointer;
}

Give the height and width with respect to the image in the background.This removes the borders and color of a button.You might also need to position it absolute so you can correctly place it where you need.I cant help you further without posting you code

To make it truly invisible you have to set outline:none; otherwise there would be a blue outline in some browsers and you have to set display:block if you need to click it and set dimensions to it

I suggest this discriminative question:

Is the open-source tool necessary in your process of making money?

• a blog engine on your commercial web site is necessary: commercial use.
• winamp for listening to music is not necessary: non-commercial use.

You can use move for this. The documentation from help move states:

Moves files and renames files and directories.

To move one or more files:
MOVE [/Y | /-Y] [drive:][path]filename1[,...] destination

To rename a directory:
MOVE [/Y | /-Y] [drive:][path]dirname1 dirname2

  [drive:][path]filename1 Specifies the location and name of the file
                          or files you want to move.
  destination             Specifies the new location of the file. Destination
                          can consist of a drive letter and colon, a
                          directory name, or a combination. If you are moving
                          only one file, you can also include a filename if
                          you want to rename the file when you move it.
  [drive:][path]dirname1  Specifies the directory you want to rename.
  dirname2                Specifies the new name of the directory.

  /Y                      Suppresses prompting to confirm you want to
                          overwrite an existing destination file.
  /-Y                     Causes prompting to confirm you want to overwrite
                          an existing destination file.

The switch /Y may be present in the COPYCMD environment variable.
This may be overridden with /-Y on the command line.  Default is
to prompt on overwrites unless MOVE command is being executed from
within a batch script.

See the following transcript for an example where it initially shows the qq1 and qq2 directories as having three and no files respectively. Then, we do the move and we find that the three files have been moved from qq1 to qq2 as expected.

You are trying to use the string as a function:

"Your new price is: $"(float(price) * 0.1)

Because there is nothing between the string literal and the (..) parenthesis, Python interprets that as an instruction to treat the string as a callable and invoke it with one argument:

>>> "Hello World!"(42)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' object is not callable

Seems you forgot to concatenate (and call str()):

easygui.msgbox("Your new price is: $" + str(float(price) * 0.1))

The next line needs fixing as well:

easygui.msgbox("Your new price is: $" + str(float(price) * 0.2))

Alternatively, use string formatting with str.format():

easygui.msgbox("Your new price is: ${:.2f}".format(float(price) * 0.1))
easygui.msgbox("Your new price is: ${:.2f}".format(float(price) * 0.2))

where {:02.2f} will be replaced by your price calculation, formatting the floating point value as a value with 2 decimals.

I'm a bit late to the answer, but you may want to do this if you want the whole element, not only the values you want to group by:

var query = doc.Elements("whatever")
               .GroupBy(element => new {
                             id = (int) element.Attribute("id"),
                             category = (int) element.Attribute("cat") })
               .Select(e => e.First());

This will give you the first whole element matching your group by selection, much like Jon Skeets second example using DistinctBy, but without implementing IEqualityComparer comparer. DistinctBy will most likely be faster, but the solution above will involve less code if performance is not an issue.

It seems like the visibility problem - the parent controller doesn't see the Component you are trying to wire.

Try to add

@ComponentScan("path to respective Component") 

to the parent controller.

C++11 standard on == for std::vector

Others have mentioned that operator== does compare vector contents and works, but here is a quote from the C++11 N3337 standard draft which I believe implies that.

We first look at Chapter 23.2.1 "General container requirements", which documents things that must be valid for all containers, including therefore std::vector.

That section Table 96 "Container requirements" which contains an entry:

Expression   Operational semantics
===========  ======================
a == b       distance(a.begin(), a.end()) == distance(b.begin(), b.end()) &&
             equal(a.begin(), a.end(), b.begin())

The distance part of the semantics means that the size of both containers are the same, but stated in a generalized iterator friendly way for non random access addressable containers. distance() is defined at 24.4.4 "Iterator operations".

Then the key question is what does equal() mean. At the end of the table we see:

Notes: the algorithm equal() is defined in Clause 25.

and in section 25.2.11 "Equal" we find its definition:

template<class InputIterator1, class InputIterator2>
bool equal(InputIterator1 first1, InputIterator1 last1,
           InputIterator2 first2);

template<class InputIterator1, class InputIterator2,
class BinaryPredicate>
bool equal(InputIterator1 first1, InputIterator1 last1,
           InputIterator2 first2, BinaryPredicate pred);

1 Returns: true if for every iterator i in the range [first1,last1) the following corresponding conditions hold: *i == *(first2 + (i - first1)), pred(*i, *(first2 + (i - first1))) != false. Otherwise, returns false.

In our case, we care about the overloaded version without BinaryPredicate version, which corresponds to the first pseudo code definition *i == *(first2 + (i - first1)), which we see is just an iterator-friendly definition of "all iterated items are the same".

Similar questions for other containers:

• how to compare two std::set?

$('#myForm').submit(function() {
    var c = confirm("Click OK to continue?");
    return c; //you can just return c because it will be true or false

If you wish to open a new project from an existing source code in the following way:

File -> Import -> General -> Existing Project into Workspace

you still have the message "Invalid Project Description". I solve it just by going in

File -> Switch Workspace

and choosing one of the recent workspaces.

I created a simple extension method that does not need a check on Enum types:

public static bool HasAnyFlag(this Enum value, Enum flags)
{
    return
        value != null && ((Convert.ToInt32(value) & Convert.ToInt32(flags)) != 0);
}

It also works on nullable enums. The standard HasFlag method does not, so I created an extension to cover that too.

public static bool HasFlag(this Enum value, Enum flags)
{
    int f = Convert.ToInt32(flags);

    return
        value != null && ((Convert.ToInt32(value) & f) == f);
}

A simple test:

[Flags]
enum Option
{
    None = 0x00,
    One = 0x01,
    Two = 0x02,
    Three = One | Two,
    Four = 0x04
}

[TestMethod]
public void HasAnyFlag()
{
    Option o1 = Option.One;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(false, o1.HasFlag(Option.Three));

    o1 |= Option.Two;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(true, o1.HasFlag(Option.Three));
}

[TestMethod]
public void HasAnyFlag_NullableEnum()
{
    Option? o1 = Option.One;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(false, o1.HasFlag(Option.Three));

    o1 |= Option.Two;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(true, o1.HasFlag(Option.Three));
}

Enjoy!

You need to specify the width and height in px:

width: 10px; height: 10px;

In addition, you can use overflow: auto; to prevent the horizontal scrollbar from showing.

Therefore, you may want to try the following:

Yocoder is right,

Inside the DataTemplate, your DataContext is set to the Rule its currently handling..

To access the parents DataContext, you can also consider using a RelativeSource in your binding:

<TextBlock Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ____Your Parent control here___ }}, Path=DataContext.SelectedRule.Name}" />

More info on RelativeSource can be found here:

http://msdn.microsoft.com/en-us/library/system.windows.data.relativesource.aspx

private static final String FILE_LOCATION = "com/input/file/somefile.txt";

//Method Body


InputStream invalidCharacterInputStream = URLClassLoader.getSystemResourceAsStream(FILE_LOCATION);

Getting this from getSystemResourceAsStream is the best option. By getting the inputstream rather than the file or the URL, works in a JAR file and as stand alone.

The existence of that piece of metadata is entirely dependent on the application that wrote the file. It's very common to load up JPG files with metadata (EXIF tags) about the file, such as a timestamp or camera information or geolocation. ID3 tags in MP3 files are also very common. But it's a lot less common to see this kind of metadata in video files.

If you just need a tool to read this data from files manually, GSpot might do the trick: http://www.videohelp.com/tools/Gspot

If you want to read this in code then I imagine each container format is going to have its own standards and each one will take a bit of research and implementation to support.

Everything in the g element is positioned relative to the current transform matrix.

To move the content, just put the transformation in the g element:

<g transform="translate(20,2.5) rotate(10)">
    <rect x="0" y="0" width="60" height="10"/>
</g>

I would say actual task is decoupled from the thread. We can pass around the task to Thread, Executor framework etc in case of Runnable, whereas with extending Thread task is coupled with thread object itself. The task isolation cannot be done in case of extending Thread. It's like we burn the task to Thread object just something like IC chip (and more specifically will not get any handle to task).

I found another very easy way to create dictionaries using itertools.

generator=itertools.combinations_with_replacement('abcd', 4 )

This will iterate through all combinations of 'a','b','c' and 'd' and create combinations with a total length of 1 to 4. ie. a,b,c,d,aa,ab.........,dddc,dddd. generator is an itertool object and you can loop through normally like this,

for password in generator:
        ''.join(password)

Each password is infact of type tuple and you can work on them as you normally do.

A simple solution is to do this formula:

A1*7+DATE(A2,1,1)

If it returns a Wednesday, simply change the formula to:

(A1*7+DATE(A2,1,1))-2

This will only work for dates within one calendar year.

Try these:

1. window.location.href = 'http://www.google.com';
2. window.location.assign("http://www.w3schools.com");
3. window.location = 'http://www.google.com';

In the meantime urllib2 seems to verify server certificates by default. The warning, that was shown in the past disappeared for 2.7.9 and I currently ran into this problem in a test environment with a self signed certificate (and Python 2.7.9).

My evil workaround (don't do this in production!):

import urllib2
import ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

urllib2.urlopen("https://your-test-server.local", context=ctx)

According to docs calling SSLContext constructor directly should work, too. I haven't tried that.

Try:

 dpkg-query -W libgtk-3-bin

Flex-boxes are the solution - and they're fantastic. I've been wanting something like this out of css for a decade. All you need is to add display: flex to your style for "Main" and flex-grow: 100 (where 100 is arbitrary - its not important that it be exactly 100). Try adding this style (colors added to make the effect visible):

<style>
    #Main {
        background-color: lightgray;
        display: flex;
    }

    #div1 {
        border: 1px solid green;   
        height: 50px; 
        display: inline-flex; 
    }
    #div2 {
        border: 1px solid blue;    
        height: 50px;
        display: inline-flex;
        flex-grow: 100;
    }
    #div3 {
        border: 1px solid orange;        
        height: 50px;
        display: inline-flex;
    }
</style>

If you need to iterate through the code points of a String (see this answer) a shorter / more readable way is to use the CharSequence#codePoints method added in Java 8:

for(int c : string.codePoints().toArray()){
    ...
}

or using the stream directly instead of a for loop:

string.codePoints().forEach(c -> ...);

There is also CharSequence#chars if you want a stream of the characters (although it is an IntStream, since there is no CharStream).

I've also tried everything but finally I'm writing below code to make URL shorter:

var curURL = window.location.href;
history.replaceState(history.state, '', '/');
window.print();
history.replaceState(history.state, '', curURL);

But you need to make a custom PRINT button for user to click.

Assuming you have the necessary privileges to run svnadmin, you need to use the dump and load commands.

Try this way

    .load(R.drawable.thumbnail)

Your question is a little unclear. If you're generating hostDict in a loop:

with open('data.txt', 'a') as outfile:
    for hostDict in ....:
        json.dump(hostDict, outfile)
        outfile.write('\n')

If you mean you want each variable within hostDict to be on a new line:

with open('data.txt', 'a') as outfile:
    json.dump(hostDict, outfile, indent=2)

When the indent keyword argument is set it automatically adds newlines.

vec1[i] = vec2[i]

will set the value of vec1[i] to the value of vec2[i]. Nothing is inserted. Your second approach is almost correct. Instead of +i+1 you need just +i

v1.insert(v1.begin()+i, v2[i])

to anyone who's using react-moment:

import Moment from 'react-moment'

inside render (use format prop to your needed format):

const now = new Date()
<Moment format="MM/DD/YYYY">{now}</Moment>

CharlesB's answer and helmbert's answer are both helpful, but it took me a while to understand them. Here's another way of putting it:

• A tag is a pointer to a commit, and commits exist independently of branches.
  • It is important to understand that tags have no direct relationship with branches - they only ever identify a commit.
    • That commit can be pointed to from any number of branches - i.e., it can be part of the history of any number of branches - including none.
  • Therefore, running git show <tag> to see a tag's details contains no reference to any branches, only the ID of the commit that the tag points to.
    • (Commit IDs (a.k.a. object names or SHA-1 IDs) are 40-character strings composed of hex. digits that are hashes over the contents of a commit; e.g.: 6f6b5997506d48fc6267b0b60c3f0261b6afe7a2)

• Branches come into play only indirectly:
  • At the time of creating a tag, by implying the commit that the tag will point to:
    • Not specifying a target for a tag defaults to the current branch's most recent commit (a.k.a. HEAD); e.g.:
      • git tag v0.1.0 # tags HEAD of *current* branch
    • Specifying a branch name as the tag target defaults to that branch's most recent commit; e.g.:
      • git tag v0.1.0 develop # tags HEAD of 'develop' branch
    • (As others have noted, you can also specify a commit ID explicitly as the tag's target.)
  • When using git describe to describe the current branch:
    • git describe [--tags] describes the current branch in terms of the commits since the most recent [possibly lightweight] tag in this branch's history.
    • Thus, the tag referenced by git describe may NOT reflect the most recently created tag overall.

Quick and Simple Code

public static bool IsValidEmail(this string email)
{
    const string pattern = @"^(?!\.)(""([^""\r\\]|\\[""\r\\])*""|" + @"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)" + @"@[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$";    
    var regex = new Regex(pattern, RegexOptions.IgnoreCase);    
    return regex.IsMatch(email);
}

The easiest way to do it is to link the CSV-file into the Access database as a table. Then you can work on this table as if it was an ordinary access table, for instance by creating an appropriate query based on this table that returns exactly what you want.

You can link the table either manually or with VBA like this

DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true

UPDATE

Dim db As DAO.Database

' Re-link the CSV Table
Set db = CurrentDb
On Error Resume Next:   db.TableDefs.Delete "tblImport":   On Error GoTo 0
db.TableDefs.Refresh
DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true
db.TableDefs.Refresh

' Perform the import
db.Execute "INSERT INTO someTable SELECT col1, col2, ... FROM tblImport " _
   & "WHERE NOT F1 IN ('A1', 'A2', 'A3')"
db.Close:   Set db = Nothing

If your environment is using both Guice and Spring and using the constructor @Inject, for example, with Play Framework, you will also run into this issue if you have mistakenly auto-completed the import with an incorrect choice of:

import com.google.inject.Inject;

Then you get the same missing default constructor error even though the rest of your source with @Inject looks exactly the same way as other working components in your project and compile without an error.

Correct that with:

import javax.inject.Inject;

Do not write a default constructor with construction time injection.

Linux In current Vscode 1.44.1 version

we could use ctrl+pageup for next editor and ctrl+pagedown for previous editor.

If there is a need to change

ctrl+shift+p > Preferences:Open Keyboard Shortcuts.

search for

nextEditor

change if needed by clicking it.

If url helper is loaded, use

current_url();

will be better

You have by default the static endpoint for static files. Also Flask application has the following arguments:

static_url_path: can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder folder.

static_folder: the folder with static files that should be served at static_url_path. Defaults to the 'static' folder in the root path of the application.

It means that the filename argument will take a relative path to your file in static_folder and convert it to a relative path combined with static_url_default:

url_for('static', filename='path/to/file')

will convert the file path from static_folder/path/to/file to the url path static_url_default/path/to/file.

So if you want to get files from the static/bootstrap folder you use this code:

<link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='bootstrap/bootstrap.min.css') }}">

Which will be converted to (using default settings):

<link rel="stylesheet" type="text/css" href="static/bootstrap/bootstrap.min.css">

Also look at url_for documentation.

In my case, I already pushed to the repo. Ouch!

You can revert a specific commit while keeping the changes in your local files by doing:

git revert -n <sha>

This way I was able to keep the changes which I needed and undid a commit which had already been pushed.

in Bitbucket go to branches in left hand side menu.

1. Select your branch you want to delete.
2. Go to action column, click on three dots (...) and select delete.

You are always passing in true to the toggleMethod, so it will always "show" the table. I would create a global variable that you can flip inside the toggle method instead.

Alternatively you can check the visibility state of the table instead of an explicit variable

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

You need to put -1 to round half down and after that multiply by -1 like the example down bellow.

<script type="text/javascript">

  function roundNumber(number, precision, isDown) {
    var factor = Math.pow(10, precision);
    var tempNumber = number * factor;
    var roundedTempNumber = 0;
    if (isDown) {
      tempNumber = -tempNumber;
      roundedTempNumber = Math.round(tempNumber) * -1;
    } else {
      roundedTempNumber = Math.round(tempNumber);
    }
    return roundedTempNumber / factor;
  }
</script>

<div class="col-sm-12">
  <p>Round number 1.25 down: <script>document.write(roundNumber(1.25, 1, true));</script>
  </p>
  <p>Round number 1.25 up: <script>document.write(roundNumber(1.25, 1, false));</script></p>
</div>

In addition to the tools and methodes provided in the other anwers, static code analysis tools can be used to detect memory leaks (and other issues as well). A free an robust tool is Cppcheck. But there are a lot of other tools available. Wikipedia has a list of static code analysis tools.

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

In the current version of RestSharp (105.2.3.0) you can add a JSON object to the request body with:

request.AddJsonBody(new { A = "foo", B = "bar" });

This method sets content type to application/json and serializes the object to a JSON string.

You have declared an array that can store 8 elements not 9.

this.posStatus = new int[8]; 

It means postStatus will contain 8 elements from index 0 to 7.

If you've exported the environment variable:

export demoPath=/usr/local/demo

you can simply refer to it by name in the makefile (make imports all the environment variables you have set):

DEMOPATH = ${demoPath}    # Or $(demoPath) if you prefer.

If you've not exported the environment variable, it is not accessible until you do export it, or unless you pass it explicitly on the command line:

make DEMOPATH="${demoPath}" …

If you are using a C shell derivative, substitute setenv demoPath /usr/local/demo for the export command.

If you want to have this work with images of any height and without fixing the height, just do this:

$('#myCarousel').on("slide.bs.carousel", function(){
     $(".carousel-control",this).css('top',($(".active img",this).height()*0.46)+'px');
     $(this).off("slide.bs.carousel");
});

%USERNAME% is the correct answer in batch and other in Windows environments.

Another option is to use %USERPROFILE% to get the user's path, like C:\Users\username.

Remove the inline event handler and do it completly unobtrusive, like

?$('????#race').bind('change', function(){
  var $this = $(this),
      id    = $this[0].id;

  if(/^other$/.test($(this).val())){
      $this.replaceWith($('<input/>', {
          type: 'text',
          name:  id,
          id: id
      }));
  }
});???

You have two options without doing approximate stuff with CSS. The first option is to use javascript to remove whitespace-only children from tags. A nicer option though is to use the fact that whitespace can exist inside tags without it having a meaning. Like so:

<div id="[divContainer_Id]"
    ><img src="[image1_url]" alt="img1"
    /><img src="[image2_url]" alt="img2"
    /><img src="[image3_url]" alt="img3"
    /><img src="[image4_url]" alt="img4"
    /><img src="[image5_url]" alt="img5"
    /><img src="[image6_url]" alt="img6"
/></div>

When using SQLFiddle, make sure that the separator is set to GO. Also the schema build script is executed in a different connection from the run script, so a temp table created in the one is not visible in the other. This fiddle shows that your code is valid and working in SQL 2012:

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

The primary difference is that the LINQ operators for IQueryable<T> take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to a method.

• IEnumerable<T> is great for working with sequences that are iterated in-memory, but
• IQueryable<T> allows for out-of memory things like a remote data source, such as a database or web service.

Query execution:

• Where the execution of a query is going to be performed "in process", typically all that's required is the code (as code) to execute each part of the query.

• Where the execution will be performed out-of-process, the logic of the query has to be represented in data such that the LINQ provider can convert it into the appropriate form for the out-of-memory execution - whether that's an LDAP query, SQL or whatever.

My Visual Studio 2015 RTM was also very slow using ReSharper 9.1.2, but it has worked fine since I upgraded to 9.1.3 (see ReSharper 9.1.3 to the Rescue). Perhaps a cue.

• if you downloaded redis yourself (not apt-get install redis-server) and then edited the redis.conf with the above suggestions, make sure your start redis with the config like so: ./src/redis-server redis.conf

For those who are getting the error as:

I/O error on POST request for "anothermachine:31112/url/path";: class path 
resource [fileName.csv] cannot be resolved to URL because it does not exist.

It can be resolved by using the

LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
map.add("file", new FileSystemResource(file));

If the file is not present in the classpath, and an absolute path is required.

Just for the record and in case you have a browser supporting ES6, here's a solution with reduce:

Object.keys(obj).reduce((prev, key, i) => (
  `${prev}${i!==0?'&':''}${key}=${obj[key]}`
), '');

And here's a snippet in action!

// Just for test purposes_x000D_
let obj = {param1: 12, param2: "test"};_x000D_
_x000D_
// Actual solution_x000D_
let result = Object.keys(obj).reduce((prev, key, i) => (_x000D_
  `${prev}${i!==0?'&':''}${key}=${obj[key]}`_x000D_
), '');_x000D_
_x000D_
// Run the snippet to show what happens!_x000D_
console.log(result);

In your vimrc file you can specify to automatically use the system clipboard for copy and paste.

On Windows set:

set clipboard=unnamed

On Linux set (vim 7.3.74+):

set clipboard=unnamedplus

NOTE: You may need to use an up to date version of Vim for these to work.

Other answers are correct -- whether a character is invisible or not depends on what font you use. This seems to be a pretty good list to me of characters that are truly invisible (not even space). It contains some chars that the other lists are missing.

JaredPar's code answer is fantastic, but I have a tip that would make it unnecessary if your generic types are not based on value type parameters. I was hung up on why the "is" operator would not work, so I have also documented the results of my experimentation for future reference. Please enhance this answer to further enhance its clarity.

TIP:

If you make certain that your GenericClass implementation inherits from an abstract non-generic base class such as GenericClassBase, you could ask the same question without any trouble at all like this:

typeof(Test).IsSubclassOf(typeof(GenericClassBase))

IsSubclassOf()

My testing indicates that IsSubclassOf() does not work on parameterless generic types such as

typeof(GenericClass<>)

whereas it will work with

typeof(GenericClass<SomeType>)

Therefore the following code will work for any derivation of GenericClass<>, assuming you are willing to test based on SomeType:

typeof(Test).IsSubclassOf(typeof(GenericClass<SomeType>))

The only time I can imagine that you would want to test by GenericClass<> is in a plug-in framework scenario.

Thoughts on the "is" operator

At design-time C# does not allow the use of parameterless generics because they are essentially not a complete CLR type at that point. Therefore, you must declare generic variables with parameters, and that is why the "is" operator is so powerful for working with objects. Incidentally, the "is" operator also can not evaluate parameterless generic types.

The "is" operator will test the entire inheritance chain, including interfaces.

So, given an instance of any object, the following method will do the trick:

bool IsTypeof<T>(object t)
{
    return (t is T);
}

This is sort of redundant, but I figured I would go ahead and visualize it for everybody.

Given

var t = new Test();

The following lines of code would return true:

bool test1 = IsTypeof<GenericInterface<SomeType>>(t);

bool test2 = IsTypeof<GenericClass<SomeType>>(t);

bool test3 = IsTypeof<Test>(t);

On the other hand, if you want something specific to GenericClass, you could make it more specific, I suppose, like this:

bool IsTypeofGenericClass<SomeType>(object t)
{
    return (t is GenericClass<SomeType>);
}

Then you would test like this:

bool test1 = IsTypeofGenericClass<SomeType>(t);

If you do not use precompiled headers in your project, set the Create/Use Precompiled Header property of source files to Not Using Precompiled Headers. To set this compiler option, follow these steps:

• In the Solution Explorer pane of the project, right-click the project name, and then click Properties.
• In the left pane, click the C/C++ folder.
• Click the Precompiled Headers node.
• In the right pane, click Create/Use Precompiled Header, and then click Not Using Precompiled Headers.

Since someone mentioned efficiency, I've benchmarked the functions given so far out of curiosity:

function startsWith1($str, $char) {
    return strpos($str, $char) === 0;
}
function startsWith2($str, $char) {
    return stripos($str, $char) === 0;
}
function startsWith3($str, $char) {
    return substr($str, 0, 1) === $char;
}
function startsWith4($str, $char){
    return $str[0] === $char;
}
function startsWith5($str, $char){
    return (bool) preg_match('/^' . $char . '/', $str);
}
function startsWith6($str, $char) {
    if (is_null($encoding)) $encoding = mb_internal_encoding();
    return mb_substr($str, 0, mb_strlen($char, $encoding), $encoding) === $char;
}

Here are the results on my average DualCore machine with 100.000 runs each

// Testing '_string'
startsWith1 took 0.385906934738
startsWith2 took 0.457293987274

startsWith5 took 0.627470016479
startsWith6 took 1.40957403183

// Tested 1000 char random string [a-z0-9] with '_' prefix

startsWith3 took 0.408898115158
startsWith4 took 0.363884925842 <-- fastest
startsWith5 took 0.638479948044
startsWith6 took 1.41304707527

As you can see, treating the haystack as array to find out the char at the first position is always the fastest solution. It is also always performing at equal speed, regardless of string length. Using strpos is faster than substr for short strings but slower for long strings, when the string does not start with the prefix. The difference is irrelevant though. stripos is incredibly slow with long strings. preg_match performs mostly the same regardless of string length, but is only mediocre in speed. The mb_substr solution performs worst, while probably being more reliable though.

Given that these numbers are for 100.000 runs, it should be obvious that we are talking about 0.0000x seconds per call. Picking one over the other for efficiency is a worthless micro-optimization, unless your app is doing startsWith checking for a living.

Option 1

If you do not need to use Authentication you can add configs to ngrok commands

ngrok http 9000 --host-header=rewrite

or

ngrok http 9000 --host-header="localhost:9000"

But in this case Authentication will not work on your website because ngrok rewriting headers and session is not valid for your ngrok domain

Option 2

If you are using webpack you can add the following configuration

devServer: {
    disableHostCheck: true
}

In that case Authentication header will be valid for your ngrok domain

Generally, there are two ways to list out installed packages - through the Command Line Interface (CLI) or in your application using the API.

Both commands will print to stdout all the versions of packages that are installed, as well as their dependencies, in a tree-structure.

CLI

npm list

Use the -g (global) flag to list out all globally-installed packages. Use the --depth=0 flag to list out only the top packages and not their dependencies.

API

In your case, you want to run this within your script, so you'd need to use the API. From the docs:

npm.commands.ls(args, [silent,] callback)

In addition to printing to stdout, the data will also be passed into the callback.

useTimezone is an older workaround. MySQL team rewrote the setTimestamp/getTimestamp code fairly recently, but it will only be enabled if you set the connection parameter useLegacyDatetimeCode=false and you're using the latest version of mysql JDBC connector. So for example:

String url =
 "jdbc:mysql://localhost/mydb?useLegacyDatetimeCode=false

If you download the mysql-connector source code and look at setTimestamp, it's very easy to see what's happening:

If use legacy date time code = false, newSetTimestampInternal(...) is called. Then, if the Calendar passed to newSetTimestampInternal is NULL, your date object is formatted in the database's time zone:

this.tsdf = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss", Locale.US);
this.tsdf.setTimeZone(this.connection.getServerTimezoneTZ());
timestampString = this.tsdf.format(x);

It's very important that Calendar is null - so make sure you're using:

setTimestamp(int,Timestamp).

... NOT setTimestamp(int,Timestamp,Calendar).

It should be obvious now how this works. If you construct a date: January 5, 2011 3:00 AM in America/Los_Angeles (or whatever time zone you want) using java.util.Calendar and call setTimestamp(1, myDate), then it will take your date, use SimpleDateFormat to format it in the database time zone. So if your DB is in America/New_York, it will construct the String '2011-01-05 6:00:00' to be inserted (since NY is ahead of LA by 3 hours).

To retrieve the date, use getTimestamp(int) (without the Calendar). Once again it will use the database time zone to build a date.

Note: The webserver time zone is completely irrelevant now! If you don't set useLegacyDatetimecode to false, the webserver time zone is used for formatting - adding lots of confusion.

Note:

It's possible MySQL my complain that the server time zone is ambiguous. For example, if your database is set to use EST, there might be several possible EST time zones in Java, so you can clarify this for mysql-connector by telling it exactly what the database time zone is:

String url =
 "jdbc:mysql://localhost/mydb?useLegacyDatetimeCode=false&serverTimezone=America/New_York";

You only need to do this if it complains.

A mask defines which bits you want to keep, and which bits you want to clear.

Masking is the act of applying a mask to a value. This is accomplished by doing:

• Bitwise ANDing in order to extract a subset of the bits in the value
• Bitwise ORing in order to set a subset of the bits in the value
• Bitwise XORing in order to toggle a subset of the bits in the value

Below is an example of extracting a subset of the bits in the value:

Mask:   00001111b
Value:  01010101b

Applying the mask to the value means that we want to clear the first (higher) 4 bits, and keep the last (lower) 4 bits. Thus we have extracted the lower 4 bits. The result is:

Mask:   00001111b
Value:  01010101b
Result: 00000101b

Masking is implemented using AND, so in C we get:

uint8_t stuff(...) {
  uint8_t mask = 0x0f;   // 00001111b
  uint8_t value = 0x55;  // 01010101b
  return mask & value;
}

Here is a fairly common use-case: Extracting individual bytes from a larger word. We define the high-order bits in the word as the first byte. We use two operators for this, &, and >> (shift right). This is how we can extract the four bytes from a 32-bit integer:

void more_stuff(uint32_t value) {             // Example value: 0x01020304
    uint32_t byte1 = (value >> 24);           // 0x01020304 >> 24 is 0x01 so
                                              // no masking is necessary
    uint32_t byte2 = (value >> 16) & 0xff;    // 0x01020304 >> 16 is 0x0102 so
                                              // we must mask to get 0x02
    uint32_t byte3 = (value >> 8)  & 0xff;    // 0x01020304 >> 8 is 0x010203 so
                                              // we must mask to get 0x03
    uint32_t byte4 = value & 0xff;            // here we only mask, no shifting
                                              // is necessary
    ...
}

Notice that you could switch the order of the operators above, you could first do the mask, then the shift. The results are the same, but now you would have to use a different mask:

uint32_t byte3 = (value & 0xff00) >> 8;

Hello There is an example:

import numpy as np
import matplotlib.pyplot as ptl

def grafica_seno_coseno():
    x = np.arange(-4,2*np.pi, 0.3)
    y = 2*np.sin(x)
    y2 = 3*np.cos(x)
    ptl.plot(x, y,  '-gD')
    ptl.plot(x, y2, '-rD')
    for xitem,yitem in np.nditer([x,y]):
        etiqueta = "{:.1f}".format(xitem)
        ptl.annotate(etiqueta, (xitem,yitem), textcoords="offset points",xytext=(0,10),ha="center")
    for xitem,y2item in np.nditer([x,y2]):
        etiqueta2 = "{:.1f}".format(xitem)
        ptl.annotate(etiqueta2, (xitem,y2item), textcoords="offset points",xytext=(0,10),ha="center")
    ptl.grid(True)
    return ptl.show()

Example 1 is for asp.net applications using forms authenication. This is common practice for internet applications because user is unauthenticated until it is authentcation against some security module.

Example 2 is for asp.net application using windows authenication. Windows Authentication uses Active Directory to authenticate users. The will prevent access to your application. I use this feature on intranet applications.

Context.getResources().getDimension(int id);

The --author option doesn't work:

*** Please tell me who you are.

Run

  git config --global user.email "[email protected]"
  git config --global user.name "Your Name"

This does:

git -c user.name='A U Thor' -c [email protected] commit

You'll want to use the process.argv array to access the command-line arguments to get the filename and the FileSystem module (fs) to read the file. For example:

// Make sure we got a filename on the command line.
if (process.argv.length < 3) {
  console.log('Usage: node ' + process.argv[1] + ' FILENAME');
  process.exit(1);
}
// Read the file and print its contents.
var fs = require('fs')
  , filename = process.argv[2];
fs.readFile(filename, 'utf8', function(err, data) {
  if (err) throw err;
  console.log('OK: ' + filename);
  console.log(data)
});

To break that down a little for you process.argv will usually have length two, the zeroth item being the "node" interpreter and the first being the script that node is currently running, items after that were passed on the command line. Once you've pulled a filename from argv then you can use the filesystem functions to read the file and do whatever you want with its contents. Sample usage would look like this:

$ node ./cat.js file.txt
OK: file.txt
This is file.txt!

[Edit] As @wtfcoder mentions, using the "fs.readFile()" method might not be the best idea because it will buffer the entire contents of the file before yielding it to the callback function. This buffering could potentially use lots of memory but, more importantly, it does not take advantage of one of the core features of node.js - asynchronous, evented I/O.

The "node" way to process a large file (or any file, really) would be to use fs.read() and process each available chunk as it is available from the operating system. However, reading the file as such requires you to do your own (possibly) incremental parsing/processing of the file and some amount of buffering might be inevitable.

I solved this problem by using the following,

@await Html.PartialAsync("_ValidationScriptsPartial")

very simple answer

Here is a property I use in one of my applications

public List<string> OperationModes
{
    get
    {
       return Enum.GetNames(typeof(SomeENUM)).ToList();
    }
}

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

This might not be a popular option, but sometimes the scripts end up being distributed in various chunks, in that case I've found this to be a quick fix

if(window.onload != null){var f1 = window.onload;}
window.onload=function(){
    //do something

    if(f1!=null){f1();}
}

then somewhere else...

if(window.onload != null){var f2 = window.onload;}
window.onload=function(){
    //do something else

    if(f2!=null){f2();}
}

this will update the onload function and chain as needed

%n is C99, works not with VC++.

You can use display:inline-block.

This property allows a DOM element to have all the attributes of a block element, but keeping it inline. There's some drawbacks, but most of the time it's good enough. Why it's good and why it may not work for you.

EDIT: The only modern browser that has some problems with it is IE7. See Quirksmode.org

I had to change /etc/profile.d/java_env.sh to point to the new path and then logout/login.

function enumKeys(_enum) {
  const entries = Object.entries(_enum).filter(e => !isNaN(Number(e[0])));
  if (!entries.length) {
    // enum has string values so we can use Object.keys
    return Object.keys(_enum);
  }
  return entries.map(e => e[1]);
}

If you need to increase MySQL Connections without MySQL restart do like below

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+
1 row in set (0.00 sec)

mysql> SET GLOBAL max_connections = 150;
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 150   |
+-----------------+-------+
1 row in set (0.00 sec)

These settings will change at MySQL Restart.

For permanent changes add below line in my.cnf and restart MySQL

max_connections = 150

from urllib.request import urlopen

# if has Chinese, apply decode()
html = urlopen("https://blog.csdn.net/qq_39591494/article/details/83934260").read().decode('utf-8')
print(html)

Swift 2 and below

let date = NSDate()
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.stringFromDate(date)
println(dateString)

And in Swift 3 and higher this would now be written as:

let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.string(from: date)

This an old question and depends more upon when you need to start your routines. Since no one wants a null reference exception it is always best to check for null first then use as needed; that alone may save you a lot of grief.

The most common reason for this type of question is when a container or custom control type attempts to access properties initialized outside of a custom class where those properties have not yet been initialized thus potentially causing null values to populate and can even cause a null reference exceptions on object types. It means your class is running before it is fully initialized - before you have finished setting your properties etc. Another possible reason for this type of question is when to perform custom graphics.

To best answer the question about when to start executing code following the form load event is to monitor the WM_Paint message or hook directly in to the paint event itself. Why? The paint event only fires when all modules have fully loaded with respect to your form load event. Note: This.visible == true is not always true when it is set true so it is not used at all for this purpose except to hide a form.

The following is a complete example of how to start executing you code following the form load event. It is recommended that you do not unnecessarily tie up the paint message loop so we'll create an event that will start executing your code outside that loop.

using System.Windows.Forms;

namespace MyProgramStartingPlaceExample {

/// <summary>
/// Main UI form object
/// </summary>
public class Form1 : Form
{

    /// <summary>
    /// Main form load event handler
    /// </summary>
    public Form1()
    {
        // Initialize ONLY. Setup your controls and form parameters here. Custom controls should wait for "FormReady" before starting up too.
        this.Text = "My Program title before form loaded";
        // Size need to see text. lol
        this.Width = 420;

        // Setup the sub or fucntion that will handle your "start up" routine
        this.StartUpEvent += StartUPRoutine;

        // Optional: Custom control simulation startup sequence:
        // Define your class or control in variable. ie. var MyControlClass new CustomControl;
        // Setup your parameters only. ie. CustomControl.size = new size(420, 966); Do not validate during initialization wait until "FormReady" is set to avoid possible null values etc. 
        // Inside your control or class have a property and assign it as bool FormReady - do not validate anything until it is true and you'll be good! 
    }

    /// <summary>
    /// The main entry point for the application which sets security permissions when set.
    /// </summary>
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }

    // Create our event handle "StartUpEvent"
    public event StartUpHandler StartUpEvent;
    //
    // Our FormReady will only be set once just he way we intendded
    // Since it is a global variable we can poll it else where as well to determine if we should begin code execution !!
    bool FormReady;
    //
    // The WM_Paint message handler: Used mostly to paint nice things to controls and screen
    protected override void OnPaint(PaintEventArgs e)
    {
        // Check if Form is ready for our code ?
        if (FormReady == false) // Place a break point here to see the initialized version of the title on the form window
        {
            // We only want this to occur once for our purpose here.
            FormReady = true;
            //
            // Fire the start up event which then will call our "StartUPRoutine" below.
            StartUpEvent();
        }
        //
        // Always call base methods unless overriding the entire fucntion
        base.OnPaint(e);
    }
    #endregion


    #region "Your StartUp event Entry point"
    //
    // Begin executuing your code here to validate properties etc. and to run your program. Enjoy!
    // Entry point is just following the very first WM_Paint message - an ideal starting place following form load
    void StartUPRoutine()
    {
        // Replace the initialized text with the following
        this.Text = "Your Code has executed after the form's load event";
        //
        // Anyway this is the momment when the form is fully loaded and ready to go - you can also use these methods for your classes to synchronize excecution using easy modifications yet here is a good starting point. 
        // Option: Set FormReady to your controls manulaly ie. CustomControl.FormReady = true; or subscribe to the StartUpEvent event inside your class and use that as your entry point for validating and unleashing its code.
        //
        // Many options: The rest is up to you!
    }
    #endregion

If you see there is a method _numpy(), e.g for an EagerTensor simply call the above method and you will get an ndarray.

Use  

It is the entity used to represent a non-breaking space. It is essentially a standard space, the primary difference being that a browser should not break (or wrap) a line of text at the point that this   occupies.

var a = 'something' + '&nbsp &nbsp &nbsp &nbsp &nbsp' + 'something'

Non-breaking Space

A common character entity used in HTML is the non-breaking space (&nbsp;).

Remember that browsers will always truncate spaces in HTML pages. If you write 10 spaces in your text, the browser will remove 9 of them. To add real spaces to your text, you can use the &nbsp; character entity.

http://www.w3schools.com/html/html_entities.asp

Demo

var a = 'something' + '&nbsp &nbsp &nbsp &nbsp &nbsp' + 'something';_x000D_
_x000D_
document.body.innerHTML = a;

CHAR is a fixed-length data type that uses as much space as possible. So a:= a||'one '; will require more space than is available. Your problem can be reduced to the following example:

declare
  v_foo char(50);
begin
  v_foo := 'A';
  dbms_output.put_line('length of v_foo(A) = ' || length(v_foo));
  -- next line will raise:
  -- ORA-06502: PL/SQL: numeric or value error: character string buffer too small
  v_foo := v_foo || 'B';
  dbms_output.put_line('length of v_foo(AB) = ' || length(v_foo));  
end;
/

Never use char. For rationale check the following question (read also the links):

• Oracle datatype: Should I use VARCHAR2 or CHAR

The docs are pretty clear on this: HashSet.add doesn't replace:

Adds the specified element to this set if it is not already present. More formally, adds the specified element e to this set if this set contains no element e2 such that (e==null ? e2==null : e.equals(e2)). If this set already contains the element, the call leaves the set unchanged and returns false.

But HashMap.put will replace:

If the map previously contained a mapping for the key, the old value is replaced.

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

Search for [ ]{2,}. This will find two or more adjacent spaces anywhere within the line. It will also match leading and trailing spaces as well as lines that consist entirely of spaces. If you don't want that, check out Alexander's answer.

Actually, you can leave out the brackets, they are just for clarity (otherwise the space character that is being repeated isn't that well visible :)).

The problem with \s{2,} is that it will also match newlines on Windows files (where newlines are denoted by CRLF or \r\n which is matched by \s{2}.

If you also want to find multiple tabs and spaces, use [ \t]{2,}.

Expanding on Abdul's answer, you can obtain a KeyedTuple instead of a discrete collection of rows by joining the columns:

q = Session.query(*User.__table__.columns + Document.__table__.columns).\
        select_from(User).\
        join(Document, User.email == Document.author).\
        filter(User.email == 'someemail').all()

Menu File → Preference → Settings →

Check the "Trim Trailing Whitespace" option - "When enabled, will trim trailing whitespace when saving a file".

Unless you're trying to upload the file using ajax, just submit the form to /upload/image.

<form enctype="multipart/form-data" action="/upload/image" method="post">
    <input id="image-file" type="file" />
</form>

If you do want to upload the image in the background (e.g. without submitting the whole form), you can use ajax:

• Asynchronous file upload (AJAX file upload) using jsp and javascript
• jQuery Ajax File Upload
• Ajax using file upload

If you're like me, you're looking for equivalent to svn update -n. The following appears to do the trick. Note that make sure to do a git fetch first so that your local repo has the appropriate updates to compare against.

$ git fetch origin
$ git diff --name-status origin/master
D       TableAudit/Step0_DeleteOldFiles.sh
D       TableAudit/Step1_PopulateRawTableList.sh
A       manbuild/staff_companies.sql
M       update-all-slave-dbs.sh

or if you want a diff from your head to the remote:

$ git fetch origin
$ git diff origin/master

IMO this solution is much easier and less error prone (and therefore much less risky) than the top solution which proposes "merge then abort".

Here is another alternative that shouldn't perform too badly (because of deferred execution):

new string(mystring.Reverse().Take(4).Reverse().ToArray());

Although an extension method for the purpose mystring.Last(4) is clearly the cleanest solution, albeit a bit more work.

I want to make clear that new Date().getTime() does in fact return a UTC value, so it is a really helpful way to store and manage dates in a way that is agnostic to localized times.

In other words, don't bother with all the UTC javascript functions. Instead, just use Date.getTime().

More info on the explanation is here: If javascript "(new Date()).getTime()" is run from 2 different Timezones.

If you want to bind an event like 'click' for all the elements having same class in the rendered DOM element then you can set up an event listener by using following parts of the code in components.ts file.

import { Component, OnInit, Renderer, ElementRef} from '@angular/core';

constructor( elementRef: ElementRef, renderer: Renderer) {
    dragulaService.drop.subscribe((value) => {
      this.onDrop(value.slice(1));
    });
}

public onDrop(args) {

  let [e, el] = args;

  this.toggleClassComTitle(e,'checked');

}


public toggleClassComTitle(el: any, name: string) {

    el.querySelectorAll('.com-item-title-anchor').forEach( function ( item ) {

      item.addEventListener('click', function(event) {
              console.log("item-clicked");

       });
    });

}

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Create a lookup table that computes font-size based on the length of the string inside your <div>.

const fontSizeLookupTable = () => {
  // lookup table looks like: [ '72px', ..., '32px', ..., '16px', ..., ]
  let a = [];
  // adjust this based on how many characters you expect in your <div>
  a.length = 32;
  // adjust the following ranges empirically
  a.fill( '72px' ,     );
  a.fill( '32px' , 4 , );
  a.fill( '16px' , 8 , );
  // add more ranges as necessary
  return a;
}

const computeFontSize = stringLength => {
  const table = fontSizeLookupTable();
  return stringLength < table.length ? table[stringLength] : '16px';

Adjust and tune all parameters by empirical test.

You can do that using javascript and AJAX technology. Have a look at jquery and at this form plug in. You only need to include two js files to register a callback for the form.submit.

You can escape shell metacharacters with ^:

echo ^<?xml version="1.0" encoding="utf-8" ?^> > myfile.xml

Note that since echo is a shell built-in it doesn't follow the usual conventions regarding quoting, so just quoting the argument will output the quotes instead of removing them.

put .; at classpath value in beginning..it will start working...it happens because it searches the class file in classpath which is mentioned in path variable.

Here is how to do it:

#!/bin/sh

abort()
{
    echo >&2 '
***************
*** ABORTED ***
***************
'
    echo "An error occurred. Exiting..." >&2
    exit 1
}

trap 'abort' 0

set -e

# Add your script below....
# If an error occurs, the abort() function will be called.
#----------------------------------------------------------
# ===> Your script goes here
# Done!
trap : 0

echo >&2 '
************
*** DONE *** 
************
'

Insert a new verse after the given verse in your stanza:

sed -i '/^lorem ipsum dolor sit amet$/ s:$:\nconsectetur adipiscing elit:' FILE

Operations on integers are exact. double is a floating point data type, and floating point operations are approximate whenever there's a fraction.

double also takes up twice as much space as int in many implementations (e.g. most 32-bit systems) .

mingw32 exists as a package for Linux. You can cross-compile and -link Windows applications with it. There's a tutorial here at the Code::Blocks forum. Mind that the command changes to x86_64-w64-mingw32-gcc-win32, for example.

Ubuntu, for example, has MinGW in its repositories:

$ apt-cache search mingw
[...]
g++-mingw-w64 - GNU C++ compiler for MinGW-w64
gcc-mingw-w64 - GNU C compiler for MinGW-w64
mingw-w64 - Development environment targeting 32- and 64-bit Windows
[...]

array_slice() is best thing to try, following are the examples:

<?php
$input = array("a", "b", "c", "d", "e");

$output = array_slice($input, 2);      // returns "c", "d", and "e"
$output = array_slice($input, -2, 1);  // returns "d"
$output = array_slice($input, 0, 3);   // returns "a", "b", and "c"

// note the differences in the array keys
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));
?>

In general, there is no way to know when something on another site has been changed. If the site offers an RSS feed, you should try that. If the site does not offer an RSS feed (or if the RSS feed doesn't include the information you're looking for), then you have to scrape and compare.

You need to assign $first and $second

$first = $_POST['first'];
$second= $_POST['second'];

Also, As Travesty3 said, you need to do your arithmetic outside of the quotes:

echo $first + $second;

Try to insert this:

DriverManager.registerDriver(new com.mysql.jdbc.Driver());

before getting the JDBC Connection.

PyInstaller will create a single-file executable if you use the --onefile option (though what it actually does is extracts then runs itself).

There's a simple PyInstaller tutorial here. If you have any questions about using it, please post them...

I've used MongoDB extensively (for the past 6 months), building a hierarchical data management system, and I can vouch for both the ease of setup (install it, run it, use it!) and the speed. As long as you think about indexes carefully, it can absolutely scream along, speed-wise.

I gather that Cassandra, due to its use with large-scale projects like Twitter, has better scaling functionality, although the MongoDB team is working on parity there. I should point out that I've not used Cassandra beyond the trial-run stage, so I can't speak for the detail.

The real swinger for me, when we were assessing NoSQL databases, was the querying - Cassandra is basically just a giant key/value store, and querying is a bit fiddly (at least compared to MongoDB), so for performance you'd have to duplicate quite a lot of data as a sort of manual index. MongoDB, on the other hand, uses a "query by example" model.

For example, say you've got a Collection (MongoDB parlance for the equivalent to a RDMS table) containing Users. MongoDB stores records as Documents, which are basically binary JSON objects. e.g:

{
   FirstName: "John",
   LastName: "Smith",
   Email: "[email protected]",
   Groups: ["Admin", "User", "SuperUser"]
}

If you wanted to find all of the users called Smith who have Admin rights, you'd just create a new document (at the admin console using Javascript, or in production using the language of your choice):

{
   LastName: "Smith",
   Groups: "Admin"
}

...and then run the query. That's it. There are added operators for comparisons, RegEx filtering etc, but it's all pretty simple, and the Wiki-based documentation is pretty good.

If you used this to secure your server: http://www.thonky.com/how-to/prevent-base-64-decode-hack/

And then got the error: Code Igniter needs mysql_pconnect() in order to run.

I figured it out once I realized all the Code Igniter websites on the server were broken, so it wasn't a localized connection issue.

Main Activity extends ActionBarActivity

toolBar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolBar);

Now you can onCreateOptionsMenu like as normal ActionBar with ToolBar.

This is my Layout

• TOP: Left Drawer - Right Drawer
  • MID: ToolBar (ActionBar)
  • BOTTOM: ListFragment

Hope you understand !have fun !

You can try:

db.execSQL("UPDATE DB_TABLE SET YOUR_COLUMN='newValue' WHERE id=6 ");

Or

ContentValues newValues = new ContentValues();
newValues.put("YOUR_COLUMN", "newValue");

db.update("YOUR_TABLE", newValues, "id=6", null);

Or

ContentValues newValues = new ContentValues();
newValues.put("YOUR_COLUMN", "newValue");

String[] args = new String[]{"user1", "user2"};
db.update("YOUR_TABLE", newValues, "name=? OR name=?", args);

It might be that the code in your service somehow breaks out of Angular's zone. This breaks change detection. This should work:

import {Component, OnInit, NgZone} from 'angular2/core';

export class RecentDetectionComponent implements OnInit {

    recentDetections: Array<RecentDetection>;

    constructor(private zone:NgZone, // <== added
        private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => { 
                 this.zone.run(() => { // <== added
                     this.recentDetections = recent;
                     console.log(this.recentDetections[0].macAddress) 
                 });
        });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        timer.subscribe(() => this.getRecentDetections());
    }
}

For other ways to invoke change detection see Triggering change detection manually in Angular

Alternative ways to invoke change detection are

ChangeDetectorRef.detectChanges()

to immediately run change detection for the current component and its children

ChangeDetectorRef.markForCheck()

to include the current component the next time Angular runs change detection

ApplicationRef.tick()

to run change detection for the whole application

For UBUNTU you can try the following command to check mysql version :

mysql --version

names = {'John', 'Joe', 'Steve'}
for names = 1, 3 do
  print (names)
end

1. You're deleting your table and replacing it with an int
2. You aren't pulling a value from the table

Try:

names = {'John','Joe','Steve'}
for i = 1,3 do
    print(names[i])
end

Since you're already using JS, you could create a hidden SELECT element on the page, and for each item you are trying to hide in that list, move it to the hidden list. This way, they can be easily restored.

I don't know a way offhand of doing it in pure CSS... I would have thought that the display:none trick would have worked.

a = ['it']
b = ['was']
c = ['annoying']

a.extend(b)
a.extend(c)

# a now equals ['it', 'was', 'annoying']

Python is dynamic language so the IDE can do only so much in terms of code intelligence and syntax checking but I personally recommend Komode IDE, it's pretty slick on OS/X and Windows. I've experienced high cpu use with Linux but not sure if it's caused by my VirtualBox environment.

You can also try Eclipse with PyDev plugin. It's heavier so performance might become a problem though.

Solution: Step1: Have to remove “lock” file which present under “.svn” hidden file. Step2: In case if there is no “lock” file then you would see “we.db” you have to open this database and need to delete content alone from the following tables – lock – wc_lock Step3: Clean your project Step4: Try to commit now. Step5: Done.

Answer : document.body.scroll = 'no';

You can use // instead of single /. That converts to int directly.

The syntax of ng-style is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:

<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>

And then in your controller:

$scope.width = '900px';
$scope.bgColor = 'red';

This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

For removing whitespace from beginning and end, use strip.

>> "  foo bar   ".strip()
"foo bar"

While this shouldn't have ever been asked on SO and got through the vetting processing in the first place, I have no idea... but I'm giving my answer anyway.

After exploring basically all of the options presented here, it turns out the simplest is often the best.

First download ffmpeg from: https://evermeet.cx/ffmpeg/

Next, after you have got your .m3u8 playlist file (most probably from the webpage source or network traffic), run this command:

ffmpeg -i "http://host/folder/file.m3u8" -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 file.mp4

I tried running it from a locally saved m4u8 file, and it didn't work, because the ffmpeg download procedure downloads the chunks which are relative to the URL, so make sure you use the website url.

TRUNCATE TABLE tablename

or

DELETE FROM tablename

The first one is usually the better choice, as DELETE FROM is slow on InnoDB.

Actually, wasn't this already answered in your other question?

Not using script:

I think I've found a stupid workaround using =cell() and a helper sheet. Thus avoiding custom functions and apps script.

=cell("address",[reference]) will provide you with a string reference (i.e. "$A$1") to the address of the cell referred to. Problem is it will not provide the sheet reference unless the cell is in a different sheet!

So:

where

This also works for named sheets. Then by all means adjust to work for your use case.

If you facing grant permission access denied problem, you can try mysql_upgrade to fix the problem:

/usr/bin/mysql_upgrade -u root -p

Login as root:

mysql -u root -p

Run this commands:

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
mysql> FLUSH PRIVILEGES;

The opposite of Raymond's solution:

sed -n '/^#/!p'

"don't print anything, except for lines that DON'T start with #"

Try this (but once clicked, it is not reversible):

HTML:

<a id="test"><img src="normal-image.png"/></a>

CSS:

a#test {
    border: 0;
}
a#test:visited img, a#test:active img {
    background-image: url(clicked-image.png);
}

If you are using traits and the trait is loaded after the class (ie. the case of autoloading) you need to load the trait beforehand.

Note: this bug is very very random; due to it's nature.

I think that it is better (for my expirience) to use: :first-of-type, :nth-of-type(), :last-of-type. It can be done whit a little changing of rules, but I was able to do much more than whit *-of-type, than *-child selectors.

output=$(*command* 2>&1) && exit_status=$? || exit_status=$?
echo $output
echo $exit_status

Example of using this to create a log file

log_event(){
timestamp=$(date '+%D %T') #mm/dd/yy HH:MM:SS
echo -e "($timestamp) $event" >> "$log_file"
}

output=$(*command* 2>&1) && exit_status=$? || exit_status=$?

if [ "$exit_status" = 0 ]
    then
        event="$output"
        log_event
    else
        event="ERROR $output"
        log_event
fi

Here's my attempt at doing this:

Step 1: Create a style named SearchViewStyle

<style name="SearchViewStyle" parent="Widget.AppCompat.SearchView">
    <!-- Gets rid of the search icon -->
    <item name="searchIcon">@drawable/search</item>
    <!-- Gets rid of the "underline" in the text -->
    <item name="queryBackground">@null</item>
    <!-- Gets rid of the search icon when the SearchView is expanded -->
    <item name="searchHintIcon">@null</item>
    <!-- The hint text that appears when the user has not typed anything -->
    <item name="queryHint">@string/search_hint</item>
</style>

Step 2: Create a layout named simple_search_view_item.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.SearchView
    android:layout_gravity="end"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    style="@style/SearchViewStyle"
    xmlns:android="http://schemas.android.com/apk/res/android" />  

Step 3: Create a menu item for this search view

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        app:actionLayout="@layout/simple_search_view_item"
        android:title="@string/search"
        android:icon="@drawable/search"
        app:showAsAction="always" />
</menu>  

Step 4: Inflate the menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_searchable_activity, menu);
    return true;
}  

Result:

The only thing I wasn't able to do was to make it fill the entire width of the Toolbar. If someone could help me do that then that'd be golden.

Run this adding DatabaseName in where condition.

  SELECT TABLE_NAME, ROW_NUMBER() OVER(ORDER BY TABLE_NAME) AS 'RowNumber' 
  FROM INFORMATION_SCHEMA.VIEWS 
  WHERE TABLE_CATALOG = 'DatabaseName'

or remove where condition adding use.

  use DataBaseName

  SELECT TABLE_NAME, ROW_NUMBER() OVER(ORDER BY TABLE_NAME) AS 'RowNumber' 
  FROM INFORMATION_SCHEMA.VIEWS 

Since you actually stored the previous LAST_INSERT_ID() into the second table, you can get it from there:

INSERT INTO table1 (title,userid) VALUES ('test',1); 
INSERT INTO table2 (parentid,otherid,userid) VALUES (LAST_INSERT_ID(),4,1);
SELECT parentid FROM table2 WHERE id = LAST_INSERT_ID();

Uncaught exception messages go to STDERR, so instead of implementing your logging in Python itself you could send STDERR to a file using whatever shell you're using to run your Python script. In a Bash script, you can do this with output redirection, as described in the BASH guide.

Examples

Append errors to file, other output to the terminal:

./test.py 2>> mylog.log

Overwrite file with interleaved STDOUT and STDERR output:

./test.py &> mylog.log

Like that:

class Zoo {
    AnimalClass: typeof Animal;

    constructor(AnimalClass: typeof Animal ) {
        this.AnimalClass = AnimalClass
        let Hector = new AnimalClass();
    }
}

Or just:

class Zoo {
    constructor(public AnimalClass: typeof Animal ) {
        let Hector = new AnimalClass();
    }
}

typeof Class is the type of the class constructor. It's preferable to the custom constructor type declaration because it processes static class members properly.

Here's the relevant part of TypeScript docs. Search for the typeof. As a part of a TypeScript type annotation, it means "give me the type of the symbol called Animal" which is the type of the class constructor function in our case.

Add this to your web config and change the catalog name which is your database name:

  <connectionStrings>
    <add name="MyConnectionString" connectionString="Data Source=SERGIO-DESKTOP\SQLEXPRESS;Initial Catalog=YourDatabaseName;Integrated Security=True;"/></connectionStrings>

Reference System.Configuration assembly in your project.

Here is how you retrieve connection string from the config file:

System.Configuration.ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

The method you are looking for is Series.combine. However, it seems some care has to be taken around datatypes. In your example, you would (as I did when testing the answer) naively call

df['col_3'] = df.col_1.combine(df.col_2, func=get_sublist)

However, this throws the error:

ValueError: setting an array element with a sequence.

My best guess is that it seems to expect the result to be of the same type as the series calling the method (df.col_1 here). However, the following works:

df['col_3'] = df.col_1.astype(object).combine(df.col_2, func=get_sublist)

df

   ID   col_1   col_2   col_3
0   1   0   1   [a, b]
1   2   2   4   [c, d, e]
2   3   3   5   [d, e, f]

zoom.cfg and global-zoom.cfg provide font size change bindings (from EmacsWiki)

• C-- or C-mousewheel-up: increases font size.
• C-+ or C-mousewheel-down: decreases font size.
• C-0 reverts font size to default.
