This worked for me: sudo dnf install java-<version>-devel

If it's clarity you're after, rather than speed, I think this is very clear:

def sortAndUniq(input):
  output = []
  for x in input:
    if x not in output:
      output.append(x)
  output.sort()
  return output

It's O(n^2) though, with the repeated use of not in for each element of the input list.

And if you want to search and replace based on the value of another field you could do a CONCAT:

update table_name set `field_name` = replace(`field_name`,'YOUR_OLD_STRING',CONCAT('NEW_STRING',`OTHER_FIELD_VALUE`,'AFTER_IF_NEEDED'));

Just to have this one here so that others will find it at once.

I had the same problem, even after following Sinhue's setup, but I solved it.

The problem was that that something (Tomcat?) was forwarding from "/" to "/index.jsp" when I had the file index.jsp in my WebContent directory. When I removed that, the request did not get forwarded anymore.

What I did to diagnose the problem was to make a catch-all request handler and printed the servlet path to the console. This showed me that even though the request I was making was for http://localhost/myapp/, the servlet path was being changed to "/index.html". I was expecting it to be "/".

@RequestMapping("*")
public String hello(HttpServletRequest request) {
    System.out.println(request.getServletPath());
    return "hello";
}

So in summary, the steps you need to follow are:

1. In your servlet-mapping use <url-pattern>/</url-pattern>
2. In your controller use RequestMapping("/")
3. Get rid of welcome-file-list in web.xml
4. Don't have any files sitting in WebContent that would be considered default pages (index.html, index.jsp, default.html, etc)

Hope this helps.

Bootstrap 3

Using Bootstrap 3's grid system:

<div class="container">
  <div class="row">
    <div class="col-xs-4">Menu</div>
    <div class="col-xs-8">
      <div class="row">
        <div class="col-md-4 col-md-push-8">Right Content</div>
        <div class="col-md-8 col-md-pull-4">Content</div>
      </div>
    </div>
  </div>
</div>

Working example: http://bootply.com/93614

Explanation

First, we set two columns that will stay in place no matter the screen resolution (col-xs-*).

Next, we divide the larger, right hand column in to two columns that will collapse on top of each other on tablet sized devices and lower (col-md-*).

Finally, we shift the display order using the matching class (col-md-[push|pull]-*). You push the first column over by the amount of the second, and pull the second by the amount of the first.

I had this problem with an existing Mongodb setup. I'm still not sure why it happened, but for some reason the Mongod process couldn't find the mongod.config file. Because it could not find the config file it tried to find the DB files in /data/db, a folder that didn't exist. However, the config file was still available so I made sure the process has permissions to the config file and run the mongod process with the --config flag as follows:

mongod --config /etc/mongod.conf

In the config file itself I had this setting:

storage:
  dbPath: /var/lib/mongodb

And this is how the process could find the real DB folder again.

Module#instance_methods

Returns an array containing the names of the public and protected instance methods in the receiver. For a module, these are the public and protected methods; for a class, they are the instance (not singleton) methods. With no argument, or with an argument that is false, the instance methods in mod are returned, otherwise the methods in mod and mod’s superclasses are returned.

module A
  def method1()  end
end
class B
  def method2()  end
end
class C < B
  def method3()  end
end

A.instance_methods                #=> [:method1]
B.instance_methods(false)         #=> [:method2]
C.instance_methods(false)         #=> [:method3]
C.instance_methods(true).length   #=> 43

With numpy:

In [128]: list_a = np.array([1, 2, 4, 6])
In [129]: filter = np.array([True, False, True, False])
In [130]: list_a[filter]

Out[130]: array([1, 4])

or see Alex Szatmary's answer if list_a can be a numpy array but not filter

Numpy usually gives you a big speed boost as well

In [133]: list_a = [1, 2, 4, 6]*10000
In [134]: fil = [True, False, True, False]*10000
In [135]: list_a_np = np.array(list_a)
In [136]: fil_np = np.array(fil)

In [139]: %timeit list(itertools.compress(list_a, fil))
1000 loops, best of 3: 625 us per loop

In [140]: %timeit list_a_np[fil_np]
10000 loops, best of 3: 173 us per loop

Note: the Nintendo 64 does have a 64-bit processor, however:

Many games took advantage of the chip's 32-bit processing mode as the greater data precision available with 64-bit data types is not typically required by 3D games, as well as the fact that processing 64-bit data uses twice as much RAM, cache, and bandwidth, thereby reducing the overall system performance.

From Webopedia:

The term double precision is something of a misnomer because the precision is not really double.
The word double derives from the fact that a double-precision number uses twice as many bits as a regular floating-point number.
For example, if a single-precision number requires 32 bits, its double-precision counterpart will be 64 bits long.

The extra bits increase not only the precision but also the range of magnitudes that can be represented.
The exact amount by which the precision and range of magnitudes are increased depends on what format the program is using to represent floating-point values.
Most computers use a standard format known as the IEEE floating-point format.

The IEEE double-precision format actually has more than twice as many bits of precision as the single-precision format, as well as a much greater range.

From the IEEE standard for floating point arithmetic

Single Precision

The IEEE single precision floating point standard representation requires a 32 bit word, which may be represented as numbered from 0 to 31, left to right.

• The first bit is the sign bit, S,
• the next eight bits are the exponent bits, 'E', and

• the final 23 bits are the fraction 'F':

  S EEEEEEEE FFFFFFFFFFFFFFFFFFFFFFF
  0 1      8 9                    31
  

The value V represented by the word may be determined as follows:

• If E=255 and F is nonzero, then V=NaN ("Not a number")
• If E=255 and F is zero and S is 1, then V=-Infinity
• If E=255 and F is zero and S is 0, then V=Infinity
• If 0<E<255 then V=(-1)**S * 2 ** (E-127) * (1.F) where "1.F" is intended to represent the binary number created by prefixing F with an implicit leading 1 and a binary point.
• If E=0 and F is nonzero, then V=(-1)**S * 2 ** (-126) * (0.F). These are "unnormalized" values.
• If E=0 and F is zero and S is 1, then V=-0
• If E=0 and F is zero and S is 0, then V=0

In particular,

0 00000000 00000000000000000000000 = 0
1 00000000 00000000000000000000000 = -0

0 11111111 00000000000000000000000 = Infinity
1 11111111 00000000000000000000000 = -Infinity

0 11111111 00000100000000000000000 = NaN
1 11111111 00100010001001010101010 = NaN

0 10000000 00000000000000000000000 = +1 * 2**(128-127) * 1.0 = 2
0 10000001 10100000000000000000000 = +1 * 2**(129-127) * 1.101 = 6.5
1 10000001 10100000000000000000000 = -1 * 2**(129-127) * 1.101 = -6.5

0 00000001 00000000000000000000000 = +1 * 2**(1-127) * 1.0 = 2**(-126)
0 00000000 10000000000000000000000 = +1 * 2**(-126) * 0.1 = 2**(-127) 
0 00000000 00000000000000000000001 = +1 * 2**(-126) * 
                                     0.00000000000000000000001 = 
                                     2**(-149)  (Smallest positive value)

Double Precision

The IEEE double precision floating point standard representation requires a 64 bit word, which may be represented as numbered from 0 to 63, left to right.

• The first bit is the sign bit, S,
• the next eleven bits are the exponent bits, 'E', and

• the final 52 bits are the fraction 'F':

  S EEEEEEEEEEE FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
  0 1        11 12                                                63
  

The value V represented by the word may be determined as follows:

• If E=2047 and F is nonzero, then V=NaN ("Not a number")
• If E=2047 and F is zero and S is 1, then V=-Infinity
• If E=2047 and F is zero and S is 0, then V=Infinity
• If 0<E<2047 then V=(-1)**S * 2 ** (E-1023) * (1.F) where "1.F" is intended to represent the binary number created by prefixing F with an implicit leading 1 and a binary point.
• If E=0 and F is nonzero, then V=(-1)**S * 2 ** (-1022) * (0.F) These are "unnormalized" values.
• If E=0 and F is zero and S is 1, then V=-0
• If E=0 and F is zero and S is 0, then V=0

You could make a helper method. Something like:

public bool IsNumeric(string input) {
    int test;
    return int.TryParse(input, out test);
}

I came to this page because I have sensitive information in my command line parameters, and didn't want them stored in the code repository. I was using System Environment variables to hold the values, which could be set on each build or development machine as needed for each purpose. Environment Variable Expansion works great in Shell Batch processes, but not Visual Studio.

Visual Studio Start Options:

However, Visual Studio wouldn't return the variable value, but the name of the variable.

Example of Issue:

My final solution after trying several here on S.O. was to write a quick lookup for the Environment variable in my Argument Processor. I added a check for % in the incoming variable value, and if it's found, lookup the Environment Variable and replace the value. This works in Visual Studio, and in my Build Environment.

foreach (string thisParameter in args)
            {
                if (thisParameter.Contains("="))
                {
                    string parameter = thisParameter.Substring(0, thisParameter.IndexOf("="));
                    string value = thisParameter.Substring(thisParameter.IndexOf("=") + 1);

                    if (value.Contains("%"))
                    {   //Workaround for VS not expanding variables in debug
                        value = Environment.GetEnvironmentVariable(value.Replace("%", ""));
                    }

This allows me to use the same syntax in my sample batch files, and in debugging with Visual Studio. No account information or URLs saved in GIT.

Example Use in Batch

In old school JavaScript, you could do this:

document.body.innerHTML = '<p id="foo">Some HTML</p>' + document.body.innerHTML;

In response to your comment:

[...] I was interested in declaring the source of a new element's attributes and events, not the innerHTML of an element.

You need to inject the new HTML into the DOM, though; that's why innerHTML is used in the old school JavaScript example. The innerHTML of the BODY element is prepended with the new HTML. We're not really touching the existing HTML inside the BODY.

I'll rewrite the abovementioned example to clarify this:

var newElement = '<p id="foo">This is some dynamically added HTML. Yay!</p>';
var bodyElement = document.body;
bodyElement.innerHTML = newElement + bodyElement.innerHTML;
// note that += cannot be used here; this would result in 'NaN'

Using a JavaScript framework would make this code much less verbose and improve readability. For example, jQuery allows you to do the following:

$('body').prepend('<p id="foo">Some HTML</p>');

• Pointers are not booleans
• Modern C/C++ compilers emit a warning when you write if (foo = bar) by accident.

Therefore I prefer

if (foo == NULL)
{
    // null case
}
else
{
    // non null case
}

or

if (foo != NULL)
{
    // non null case
}
else
{
    // null case
}

However, if I were writing a set of style guidelines I would not be putting things like this in it, I would be putting things like:

Make sure you do a null check on the pointer.

Sample for right-click menu option as well:

[HKEY_CLASSES_ROOT\*\shell\SHA1 PS check\command]
@="C:\\Windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -NoExit -Command Get-FileHash -Algorithm SHA1 '%1'"

You cannot auto increment the char values. It should be int or long(integers or floating points). Try with this,

CREATE TABLE discussion_topics (
    topic_id int(5) NOT NULL AUTO_INCREMENT,
    project_id char(36) NOT NULL,
    topic_subject VARCHAR(255) NOT NULL,
    topic_content TEXT default NULL,
    date_created DATETIME NOT NULL,
    date_last_post DATETIME NOT NULL,
    created_by_user_id char(36) NOT NULL,
    last_post_user_id char(36) NOT NULL,
    posts_count char(36) default NULL,
    PRIMARY KEY (`topic_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;

Hope this helps

I get into ElementNotVisibleException exception using selenium for functional tests on a django site with bootstrap glyphicons as links in templates as:

<a href="{% url 'item-add' %}"><span class="glyphicon glyphicon-plus text-danger"></span></a>

During my functional tests, the bootstrap style is not loaded, then trying to click on such links will raise ElementNotVisibleException. I manage to make them clickable just adding a space in the tag, like that:

<a href="{% url 'item-add' %}"><span class="glyphicon glyphicon-plus text-danger">&nbsp;</span></a>

You could do

<body onload="window.print()">
...
</body>

OpenStreetMap seems to have 10-20 per second

Wikipedia seems to be 30000 to 70000 per second spread over 300 servers (100 to 200 requests per second per machine, most of which is caches)

Geograph is getting 7000 images per week (1 upload per 95 seconds)

I found a super simple explanation about class << self , Eigenclass and different type of methods.

In Ruby, there are three types of methods that can be applied to a class:

1. Instance methods
2. Singleton methods
3. Class methods

Instance methods and class methods are almost similar to their homonymous in other programming languages.

class Foo  
  def an_instance_method  
    puts "I am an instance method"  
  end  
  def self.a_class_method  
    puts "I am a class method"  
  end  
end

foo = Foo.new

def foo.a_singleton_method
  puts "I am a singletone method"
end

Another way of accessing an Eigenclass(which includes singleton methods) is with the following syntax (class <<):

foo = Foo.new

class << foo
  def a_singleton_method
    puts "I am a singleton method"
  end
end

now you can define a singleton method for self which is the class Foo itself in this context:

class Foo
  class << self
    def a_singleton_and_class_method
      puts "I am a singleton method for self and a class method for Foo"
    end
  end
end

You can also mock your property configuration into your test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "classpath:test-context.xml" })
public class MyTest 
{ 
   @Configuration
   public static class MockConfig{
       @Bean
       public Properties myProps(){
             Properties properties = new Properties();
             properties.setProperty("default.url", "myUrl");
             properties.setProperty("property.value2", "value2");
             return properties;
        }
   }
   @Value("#{myProps['default.url']}")
   private String defaultUrl;

   @Test
   public void testValue(){
       Assert.assertEquals("myUrl", defaultUrl);
   }
}

@echo off

color 1F


@sc query >%COMPUTERNAME%_START.TXT


find /I "AcPrfMgrSvc" %COMPUTERNAME%_START.TXT >nul

IF ERRORLEVEL 0 EXIT

IF ERRORLEVEL 1 NET START "AcPrfMgrSvc"

To achieve this there are basically two methods which I frequently use:

1. Using the cursor escape character (\c) with echo -e

Example :

for i in {0..10..2}; do
  echo -e "$i \c"              
done
# 0 2 4 6 8 10

• -e flag enables the Escape characters in the string.
• \c brings the Cursor back to the current line.

OR

2. Using the printf command

Example:

for ((i = 0; i < 5; ++i)); do
  printf "$i "
done
# 0 1 2 3 4

This will never work, because the JS VM has moved on from that async_call and returned the value, which you haven't set yet.

Don't try to fight what is natural and built-in the language behaviour. You should use a callback technique or a promise.

function f(input, callback) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) { callback(result) };

}

The other option is to use a promise, have a look at Q. This way you return a promise, and then you attach a then listener to it, which is basically the same as a callback. When the promise resolves, the then will trigger.

perl -pe 's/\..*$//;s{^.*/}{}'

When you use @DataJpaTest you need to load classes using @Import explicitly. It wouldn't load you for auto.

Many others have provided good info for sleeping. I agree with Wedge that a sleep seldom the most appropriate solution.

If you are sleeping as you wait for something, then you are better off actually waiting for that thing/event. Look at Condition Variables for this.

I don't know what OS you are trying to do this on, but for threading and synchronisation you could look to the Boost Threading libraries (Boost Condition Varriable).

Moving now to the other extreme if you are trying to wait for exceptionally short periods then there are a couple of hack style options. If you are working on some sort of embedded platform where a 'sleep' is not implemented then you can try a simple loop (for/while etc) with an empty body (be careful the compiler does not optimise it away). Of course the wait time is dependant on the specific hardware in this case. For really short 'waits' you can try an assembly "nop". I highly doubt these are what you are after but without knowing why you need to wait it's hard to be more specific.

I once ran into this situation and I had the dependencies in classpath. The solution was to include javax.mail and javax.activation libraries in the container's (eg. tomcat) lib folder. Using maven -set them to provided scope and it should work. You will have shared email libs in classpath for all projects.

For me i wanted to implement a 2-way handshake, meaning:
- the parent window will load faster then the iframe
- the iframe should talk to the parent window as soon as its ready
- the parent is ready to receive the iframe message and replay

this code is used to set white label in the iframe using [CSS custom property]
code:
iframe

$(function() {
    window.onload = function() {
        // create listener
        function receiveMessage(e) {
            document.documentElement.style.setProperty('--header_bg', e.data.wl.header_bg);
            document.documentElement.style.setProperty('--header_text', e.data.wl.header_text);
            document.documentElement.style.setProperty('--button_bg', e.data.wl.button_bg);
            //alert(e.data.data.header_bg);
        }
        window.addEventListener('message', receiveMessage);
        // call parent
        parent.postMessage("GetWhiteLabel","*");
    }
});

parent

$(function() {
    // create listener
    var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
    var eventer = window[eventMethod];
    var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
    eventer(messageEvent, function (e) {
        // replay to child (iframe) 
        document.getElementById('wrapper-iframe').contentWindow.postMessage(
            {
                event_id: 'white_label_message',
                wl: {
                    header_bg: $('#Header').css('background-color'),
                    header_text: $('#Header .HoverMenu a').css('color'),
                    button_bg: $('#Header .HoverMenu a').css('background-color')
                }
            },
            '*'
        );
    }, false);
});

naturally you can limit the origins and the text, this is easy-to-work-with code
i found this examlpe to be helpful:
[Cross-Domain Messaging With postMessage]

Another option:

UPDATE `table` SET the_col = current_timestamp

Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now().

Another approach is keep that element, change the text, then append that element back

const star_icon = $(li).find('.stars svg')
$(li).find('.stars').text(repo.stargazers_count).append(star_icon)

Well, it would be easier to exclude them in the first place:

authorsList = authorsList.Where(x => x.FirstName != "Bob").ToList();

However, that would just change the value of authorsList instead of removing the authors from the previous collection. Alternatively, you can use RemoveAll:

authorsList.RemoveAll(x => x.FirstName == "Bob");

If you really need to do it based on another collection, I'd use a HashSet, RemoveAll and Contains:

var setToRemove = new HashSet<Author>(authors);
authorsList.RemoveAll(x => setToRemove.Contains(x));

Mathew's answer works for the terminal python shell, but it didn't work for IDLE shell in my case because many versions of python existed before I replaced them all with Python2.7.7. How I solved the problem with IDLE.

1. In terminal, cd /Applications/Python\ 2.7/IDLE.app/Contents/Resources/
2. then sudo nano idlemain.py, enter password if required.
3. after os.chdir(os.path.expanduser('~/Documents')) this line, I added sys.path.append("/Users/admin/Downloads....") NOTE: replace contents of the quotes with the directory where python module to be added
4. to save the change, ctrl+x and enter Now open idle and try to import the python module, no error for me!!!

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable

jQuery(function(){
    //here it is a closure variable
    var a_href;
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

To make the variable global, one solution is to declare the variable in global scope

var a_href;
jQuery(function(){
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

another is to set the variable as a property of the window object

window.a_href = $(this).attr('href')

Why console printing undefined

You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError

svn log --verbose -r 42

Are you trying to do logical equality utilizing the object's .equals method? You can do this utilizing the argThat matcher that is included in Mockito

import static org.mockito.Matchers.argThat

Next you can implement your own argument matcher that will defer to each objects .equals method

private class ObjectEqualityArgumentMatcher<T> extends ArgumentMatcher<T> {
    T thisObject;

    public ObjectEqualityArgumentMatcher(T thisObject) {
        this.thisObject = thisObject;
    }

    @Override
    public boolean matches(Object argument) {
        return thisObject.equals(argument);
    }
}

Now using your code you can update it to read...

Object obj = getObject();
Mockeable mock= Mockito.mock(Mockeable.class);
Mockito.when(mock.mymethod(obj)).thenReturn(null);

Testeable obj = new Testeable();
obj.setMockeable(mock);
command.runtestmethod();

verify(mock).mymethod(argThat(new ObjectEqualityArgumentMatcher<Object>(obj)));

If you are just going for EXACT equality (same object in memory), just do

verify(mock).mymethod(obj);

This will verify it was called once.

I had the same exception in JPA 2 using eclipse link. I had an @embedded class with one to one relationship with an entity. By mistake ,in the embedded class, i had also the annotation @Table("TRADER"). When the DB was created by the JPA from the entities it also created a table TRADER (which was a wrong as the Trader entity was embedded to the main entity) and the existence of that table was causing the above exception every time i was trying to persist my entity. After deleting the TRADER table the exception disappered.

You have to put your script tag after the one that references Angular. Move it out of the head:

<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="main.js"></script>

The way you've set it up now, your script runs before Angular is loaded on the page.

Groovy maps can be used with the property property, so you can just do:

def x = mymap.likes

If the key you are looking for (for example 'likes.key') contains a dot itself, then you can use the syntax:

def x = mymap.'likes.key'

The simplest way is using pip command:

pip list | grep Keras

padding-right works for me in Firefox/Chrome on Windows but not in IE. Welcome to the wonderful world of IE standards non-compliance.

The "common knowledge" of programming is that x += y is an equivalent shorthand notation of x = x + y. As long as x and y are of the same type (for example, both are ints), you may consider the two statements equivalent.

However, in Java, x += y is not identical to x = x + y in general.

If x and y are of different types, the behavior of the two statements differs due to the rules of the language. For example, let's have x == 0 (int) and y == 1.1 (double):

    int x = 0;
    x += 1.1;    // just fine; hidden cast, x == 1 after assignment
    x = x + 1.1; // won't compile! 'cannot convert from double to int'

+= performs an implicit cast, whereas for + you need to explicitly cast the second operand, otherwise you'd get a compiler error.

Quote from Joshua Bloch's Java Puzzlers:

(...) compound assignment expressions automatically cast the result of the computation they perform to the type of the variable on their left-hand side. If the type of the result is identical to the type of the variable, the cast has no effect. If, however, the type of the result is wider than that of the variable, the compound assignment operator performs a silent narrowing primitive conversion [JLS 5.1.3].

You can specify both max post size and max file size limit in php.ini

post_max_size = 64M
upload_max_filesize = 64M

Well in general:

List<String> names = new ArrayList<String>();
names.add("john");
names.add("ann");

String[] namesArr = new String[names.size()];
for (int i = 0; i < names.size(); i++) {
    namesArr[i] = names.get(i);  
}

Or better yet, using built in:

List<String> names = new ArrayList<String>();
String[] namesArr = names.toArray(new String[names.size()]);

Use

SELECT length(yourfield) FROM table;

Assuming the submodule's repository does contain a commit you want to use (unlike the commit that is referenced from current state of the super-project), there are two ways to do it.

The first requires you to already know the commit from the submodule that you want to use. It works from the “inside, out” by directly adjusting the submodule then updating the super-project. The second works from the “outside, in” by finding the super-project's commit that modified the submodule and then reseting the super-project's index to refer to a different submodule commit.

Inside, Out

If you already know which commit you want the submodule to use, cd to the submodule, check out the commit you want, then git add and git commit it back in the super-project.

Example:

$ git submodule update
fatal: reference is not a tree: e47c0a16d5909d8cb3db47c81896b8b885ae1556
Unable to checkout 'e47c0a16d5909d8cb3db47c81896b8b885ae1556' in submodule path 'sub'

Oops, someone made a super-project commit that refers to an unpublished commit in the submodule sub. Somehow, we already know that we want the submodule to be at commit 5d5a3ee314476701a20f2c6ec4a53f88d651df6c. Go there and check it out directly.

Checkout in the Submodule

$ cd sub
$ git checkout 5d5a3ee314476701a20f2c6ec4a53f88d651df6c
Note: moving to '5d5a3ee314476701a20f2c6ec4a53f88d651df6c' which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 5d5a3ee... quux
$ cd ..

Since we are checking out a commit, this produces a detached HEAD in the submodule. If you want to make sure that the submodule is using a branch, then use git checkout -b newbranch <commit> to create and checkout a branch at the commit or checkout the branch that you want (e.g. one with the desired commit at the tip).

Update the Super-project

A checkout in the submodule is reflected in the super-project as a change to the working tree. So we need to stage the change in the super-project's index and verify the results.

$ git add sub

Check the Results

$ git submodule update

If you are not sure which commit you should use from the submodule, you can look at the history in the superproject to guide you. You can also manage the reset directly from the super-project.

This is the same situation as above. But this time we will focus on fixing it from the super-project instead of dipping into the submodule.

OK, it looks like it went bad in ce5d37c, so we will restore the submodule from its parent (ce5d37c~).

Alternatively, you can take the submodule's commit from the patch text (5d5a3ee314476701a20f2c6ec4a53f88d651df6c) and use the above “inside, out” process instead.

I add new environment variable "ANDROID_SDK_HOME" and set it, like my path to android SDK folder (c:/Android) and it's work!

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

That's my favorite way prior to Java 8:

Date date = new GregorianCalendar(year, month - 1, day).getTime();

I'd say this is a cleaner approach than:

calendar.set(year, month - 1, day, 0, 0);

Also it's possible to use attribute [FromHeader] for web methods parameters (or properties in a Model class) which should be sent in custom headers. Something like this:

[HttpGet]
public ActionResult Products([FromHeader(Name = "User-Identity")]string userIdentity)

At least it works fine for ASP.NET Core 2.1 and Swashbuckle.AspNetCore 2.5.0.

A friend and I have figured out how to call Bernardo Damele's sys_eval UDF, but the solution isn't as elegant as I'd like. Here's what we did:

1. Since we're using Windows, we had to compile the UDF library for Windows using Roland Bouman's instructions and install them on our MySQL server.
2. We created a stored procedure that calls sys_eval.
3. We created a trigger that calls the stored procedure.

Stored Procedure code:

DELIMITER $$
CREATE PROCEDURE udfwrapper_sp
(p1   DOUBLE,
 p2   DOUBLE,
 p3 BIGINT)
BEGIN
 DECLARE cmd CHAR(255);
 DECLARE result CHAR(255);
 SET cmd = CONCAT('C:/xampp/php/php.exe -f "C:/xampp/htdocs/phpFile.php" ', p1, ' ', p2, ' ', p3);
 SET result = sys_eval(cmd);
END$$;

Trigger code:

CREATE TRIGGER udfwrapper_trigger AFTER INSERT ON sometable
FOR EACH ROW
CALL udfwrapper_sp(NEW.Column1, NEW.Column2, NEW.Column3);

I'm not thrilled about having the stored procedure, and I don't know if it creates extra overhead, but it does work. Each time a row is added to sometable, the trigger fires.

Assuming the connection is established and is available in global scope;

//Check if a value exists in a table
function record_exists ($table, $column, $value) {
    global $connection;
    $query = "SELECT * FROM {$table} WHERE {$column} = {$value}";
    $result = mysql_query ( $query, $connection );
    if ( mysql_num_rows ( $result ) ) {
        return TRUE;
    } else {
        return FALSE;
    }
}

Usage: Assuming that the value to be checked is stored in the variable $username;

if (record_exists ( 'employee', 'username', $username )){
    echo "Username is not available. Try something else.";
} else {
    echo "Username is available";
}

Strings are hard work in C.

#include <stdio.h>

int main()
{
   int i;
   char buf[12];

   for (i = 0; i < 100; i++) {
      snprintf(buf, 12, "pre_%d_suff", i); // puts string into buffer
      printf("%s\n", buf); // outputs so you can see it
   }
}

The 12 is enough bytes to store the text "pre_", the text "_suff", a string of up to two characters ("99") and the NULL terminator that goes on the end of C string buffers.

This will tell you how to use snprintf, but I suggest a good C book!

This was a fun question! Another way to handle this for variable length lists is to build a function that takes full advantage of the .format method and list unpacking. In the following example I don't use any fancy formatting, but that can easily be changed to suit your needs.

list_1 = [1,2,3,4,5,6]
list_2 = [1,2,3,4,5,6,7,8]

# Create a function that can apply formatting to lists of any length:
def ListToFormattedString(alist):
    # Create a format spec for each item in the input `alist`.
    # E.g., each item will be right-adjusted, field width=3.
    format_list = ['{:>3}' for item in alist] 

    # Now join the format specs into a single string:
    # E.g., '{:>3}, {:>3}, {:>3}' if the input list has 3 items.
    s = ','.join(format_list)

    # Now unpack the input list `alist` into the format string. Done!
    return s.format(*alist)

# Example output:
>>>ListToFormattedString(list_1)
'  1,  2,  3,  4,  5,  6'
>>>ListToFormattedString(list_2)
'  1,  2,  3,  4,  5,  6,  7,  8'

You can't go through the details of the method by using the step over. If you want to skip the current line, you can use step over, then you only need to press the F6 for only once to move to the next line. And if you think there's someting wrong within the method, use F5 to examine the details.

I'm developing on iOS 6 using Storyboards.

I was having the same issue, but I could not find the "Identifier" field in the inspector. Instead, just set the field named "Storyboard ID" to what you would name the Identifier. This field can be found under the "Show the Identity inspector" tab in the inspector.

[Note - comments below indicate that some people have found that they need to (also?) set the field "Restoration ID" just below the Storyboard ID in the inspector. Clicking on "Use Storyboard ID" does not seem to be enough.]

There's an image below for reference: (in this instance I've named my identifier the same as my class)

As mrjrdnthms points out in his comment on the accepted answer, this no longer works on Chrome (it always fires the mousemove), I've adapted Gustavo's answer (since I'm using jQuery) to address the Chrome behavior.

var currentPos = [];

$(document).on('mousedown', function (evt) {

   currentPos = [evt.pageX, evt.pageY]

  $(document).on('mousemove', function handler(evt) {

    currentPos=[evt.pageX, evt.pageY];
    $(document).off('mousemove', handler);

  });

  $(document).on('mouseup', function handler(evt) {

    if([evt.pageX, evt.pageY].equals(currentPos))
      console.log("Click")
    else
      console.log("Drag")

    $(document).off('mouseup', handler);

  });

});

This should would work

List<TestA> testAList = new ArrayList<>();
List<TestB> testBList = new ArrayList<>()
testAList.addAll(new ArrayList<>(testBList));

This is a question of style (or preference) since the interpreter does not care. Personally I would try not to make the final statement of a function which returns a value at an indent level other than the function base. The else in example 1 obscures, if only slightly, where the end of the function is.

By preference I use:

return A+1 if (A > B) else A-1

As it obeys both the good convention of having a single return statement as the last statement in the function (as already mentioned) and the good functional programming paradigm of avoiding imperative style intermediate results.

For more complex functions I prefer to break the function into multiple sub-functions to avoid premature returns if possible. Otherwise I revert to using an imperative style variable called rval. I try not to use multiple return statements unless the function is trivial or the return statement before the end is as a result of an error. Returning prematurely highlights the fact that you cannot go on. For complex functions that are designed to branch off into multiple subfunctions I try to code them as case statements (driven by a dict for instance).

Some posters have mentioned speed of operation. Speed of Run-time is secondary for me since if you need speed of execution Python is not the best language to use. I use Python as its the efficiency of coding (i.e. writing error free code) that matters to me.

Check settings.gradle. You'll find this : include ':app'

Just add your own module name and it should look like this :

include ':app', ':yourModuleName'

Sync.

That's it.

There are many reasons why one might run into this error and thus a good checklist of what to check first helps considerably.

Let's consider that we are troubleshooting the following line:

require "/path/to/file"

Checklist

1. Check the file path for typos

• either check manually (by visually checking the path)

• or move whatever is called by require* or include* to its own variable, echo it, copy it, and try accessing it from a terminal:

  $path = "/path/to/file";
  
  echo "Path : $path";
  
  require "$path";
  

  Then, in a terminal:

  cat <file path pasted>
  

2. Check that the file path is correct regarding relative vs absolute path considerations

• if it is starting by a forward slash "/" then it is not referring to the root of your website's folder (the document root), but to the root of your server.
  • for example, your website's directory might be /users/tony/htdocs
• if it is not starting by a forward slash then it is either relying on the include path (see below) or the path is relative. If it is relative, then PHP will calculate relatively to the path of the current working directory.
  • thus, not relative to the path of your web site's root, or to the file where you are typing
  • for that reason, always use absolute file paths

Best practices :

In order to make your script robust in case you move things around, while still generating an absolute path at runtime, you have 2 options :

1. use require __DIR__ . "/relative/path/from/current/file". The __DIR__ magic constant returns the directory of the current file.

2. define a SITE_ROOT constant yourself :

   • at the root of your web site's directory, create a file, e.g. config.php

   • in config.php, write

     define('SITE_ROOT', __DIR__);
     

   • in every file where you want to reference the site root folder, include config.php, and then use the SITE_ROOT constant wherever you like :

     require_once __DIR__."/../config.php";
     ...
     require_once SITE_ROOT."/other/file.php";
     

These 2 practices also make your application more portable because it does not rely on ini settings like the include path.

3. Check your include path

Another way to include files, neither relatively nor purely absolutely, is to rely on the include path. This is often the case for libraries or frameworks such as the Zend framework.

Such an inclusion will look like this :

include "Zend/Mail/Protocol/Imap.php"

In that case, you will want to make sure that the folder where "Zend" is, is part of the include path.

You can check the include path with :

echo get_include_path();

You can add a folder to it with :

set_include_path(get_include_path().":"."/path/to/new/folder");

4. Check that your server has access to that file

It might be that all together, the user running the server process (Apache or PHP) simply doesn't have permission to read from or write to that file.

To check under what user the server is running you can use posix_getpwuid :

$user = posix_getpwuid(posix_geteuid());

var_dump($user);

To find out the permissions on the file, type the following command in the terminal:

ls -l <path/to/file>

and look at permission symbolic notation

5. Check PHP settings

If none of the above worked, then the issue is probably that some PHP settings forbid it to access that file.

Three settings could be relevant :

1. open_basedir
   • If this is set PHP won't be able to access any file outside of the specified directory (not even through a symbolic link).
   • However, the default behavior is for it not to be set in which case there is no restriction
   • This can be checked by either calling phpinfo() or by using ini_get("open_basedir")
   • You can change the setting either by editing your php.ini file or your httpd.conf file
2. safe mode
   • if this is turned on restrictions might apply. However, this has been removed in PHP 5.4. If you are still on a version that supports safe mode upgrade to a PHP version that is still being supported.
3. allow_url_fopen and allow_url_include
   • this applies only to including or opening files through a network process such as http:// not when trying to include files on the local file system
   • this can be checked with ini_get("allow_url_include") and set with ini_set("allow_url_include", "1")

Corner cases

If none of the above enabled to diagnose the problem, here are some special situations that could happen :

1. The inclusion of library relying on the include path

It can happen that you include a library, for example, the Zend framework, using a relative or absolute path. For example :

require "/usr/share/php/libzend-framework-php/Zend/Mail/Protocol/Imap.php"

But then you still get the same kind of error.

This could happen because the file that you have (successfully) included, has itself an include statement for another file, and that second include statement assumes that you have added the path of that library to the include path.

For example, the Zend framework file mentioned before could have the following include :

include "Zend/Mail/Protocol/Exception.php" 

which is neither an inclusion by relative path, nor by absolute path. It is assuming that the Zend framework directory has been added to the include path.

In such a case, the only practical solution is to add the directory to your include path.

2. SELinux

If you are running Security-Enhanced Linux, then it might be the reason for the problem, by denying access to the file from the server.

To check whether SELinux is enabled on your system, run the sestatus command in a terminal. If the command does not exist, then SELinux is not on your system. If it does exist, then it should tell you whether it is enforced or not.

To check whether SELinux policies are the reason for the problem, you can try turning it off temporarily. However be CAREFUL, since this will disable protection entirely. Do not do this on your production server.

setenforce 0

If you no longer have the problem with SELinux turned off, then this is the root cause.

To solve it, you will have to configure SELinux accordingly.

The following context types will be necessary :

• httpd_sys_content_t for files that you want your server to be able to read
• httpd_sys_rw_content_t for files on which you want read and write access
• httpd_log_t for log files
• httpd_cache_t for the cache directory

For example, to assign the httpd_sys_content_t context type to your website root directory, run :

semanage fcontext -a -t httpd_sys_content_t "/path/to/root(/.*)?"
restorecon -Rv /path/to/root

If your file is in a home directory, you will also need to turn on the httpd_enable_homedirs boolean :

setsebool -P httpd_enable_homedirs 1

In any case, there could be a variety of reasons why SELinux would deny access to a file, depending on your policies. So you will need to enquire into that. Here is a tutorial specifically on configuring SELinux for a web server.

3. Symfony

If you are using Symfony, and experiencing this error when uploading to a server, then it can be that the app's cache hasn't been reset, either because app/cache has been uploaded, or that cache hasn't been cleared.

You can test and fix this by running the following console command:

cache:clear

4. Non ACSII characters inside Zip file

Apparently, this error can happen also upon calling zip->close() when some files inside the zip have non-ASCII characters in their filename, such as "é".

A potential solution is to wrap the file name in utf8_decode() before creating the target file.

Credits to Fran Cano for identifying and suggesting a solution to this issue

In my case, I already had a period(.) and also a comma(,), so what worked for me was to replace the comma(,) with an empty string like below:

parseFloat('3,000.78'.replace(',', '')) 

This is assuming that the amount from the existing database is 3,000.78. The results are: 3000.78 without the initial comma(,).

For files in folder named /files

for i in `IFS="";find /files -name *\ *`
do
   echo $i
done > /tmp/list


while read line
do
   mv "$line" `echo $line | sed 's/ /_/g'`
done < /tmp/list

rm /tmp/list

I recall hearing a Clojure talk where he got to run one of his apps on some specialized machine at a trade show with thousands of cores (9000?), and it loaded them all. Unfortunately, I can't find the link right now (help?).

Based on that, I think it's safe to say that the hardware and your code are the limiting factors, not the JVM.

This message displays when Internet Explorer reaches the maximum number of synchronous instructions for a piece of JavaScript. The default maximum is 5,000,000 instructions, you can increase this number on a single machine by editing the registry.

Internet Explorer now tracks the total number of executed script statements and resets the value each time that a new script execution is started, such as from a timeout or from an event handler, for the current page with the script engine. Internet Explorer displays a "long-running script" dialog box when that value is over a threshold amount.

The only way to solve the problem for all users that might be viewing your page is to break up the number of iterations your loop performs using timers, or refactor your code so that it doesn't need to process as many instructions.

Breaking up a loop with timers is relatively straightforward:

var i=0;
(function () {
    for (; i < 6000000; i++) {
        /*
            Normal processing here
        */

        // Every 100,000 iterations, take a break
        if ( i > 0 && i % 100000 == 0) {
            // Manually increment `i` because we break
            i++;
            // Set a timer for the next iteration 
            window.setTimeout(arguments.callee);
            break;
        }
    }
})();

Your also have to register the receiver in onCreate(), like this:

IntentFilter filter = new IntentFilter();
filter.addAction("csinald.meg");
registerReceiver(receiver, filter);

You need to reference the namespace

using System.Windows.Form;

and then add in the code

protected void Button1_Click(object sender, EventArgs e)
    {
        MessageBox.Show(" Hi....");

    }

In-order, Pre-order, and Post-order traversals are Depth-First traversals.

For a Graph, the complexity of a Depth First Traversal is O(n + m), where n is the number of nodes, and m is the number of edges.

Since a Binary Tree is also a Graph, the same applies here. The complexity of each of these Depth-first traversals is O(n+m).

Since the number of edges that can originate from a node is limited to 2 in the case of a Binary Tree, the maximum number of total edges in a Binary Tree is n-1, where n is the total number of nodes.

The complexity then becomes O(n + n-1), which is O(n).

I am using Intellij Idea 2017 and I got into the same problem. What solved the problem for me was to simply

1. close the project in intelliJ
2. File -> New -> project from existing resources
3. use Import from external model (if any)
4. open the project again.

Need to list all triggers in SQL Server database with table name and table's schema

This URL have set of queries by which you can get the list of triggers associated with particular table.

I believe you are working in sqlserver following are the steps to get modify triggers

To modify a trigger

1. Expand a server group, and then expand a server.

2. Expand Databases, expand the database in which the table containing the trigger belongs, and then click Tables.

3. In the details pane, right-click the table on which the trigger exists, point to All Tasks, and then click Manage Triggers.

4. In Name, select the name of the trigger.

5. Change the text of the trigger in the Text field as necessary. Press CTRL+TAB to indent the text of a SQL Server Enterprise Manager trigger.

6. To check the syntax of the trigger, click Check Syntax.

Another option, in addition to using OPENQUERY and xp_cmdshell, is to use SQLCLR (SQL Server's "CLR Integration" feature). Not only is the SQLCLR option more secure than those other two methods, but there is also the potential benefit of being able to call the stored procedure in the current session such that it would have access to any session-based objects or settings, such as:

• temporary tables
• temporary stored procedures
• CONTEXT_INFO

This can be achieved by using "context connection = true;" as the ConnectionString. Just keep in mind that all other restrictions placed on T-SQL User-Defined Functions will be enforced (i.e. cannot have any side-effects).

If you use a regular connection (i.e. not using the context connection), then it will operate as an independent call, just like it does when using the OPENQUERY and xp_cmdshell methods.

HOWEVER, please keep in mind that if you will be using a function that calls a stored procedure (regardless of which of the 3 noted methods you use) in a statement that affects more than 1 row, then the behavior cannot be expected to run once per row. As @MartinSmith mentioned in a comment on @MatBailie's answer, the Query Optimizer does not guarantee either the timing or number of executions of functions. But if you are using it in a SET @Variable = function(); statement or SELECT * FROM function(); query, then it should be ok.

An example of using a .NET / C# SQLCLR user-defined function to execute a stored procedure is shown in the following article (which I wrote):

Stairway to SQLCLR Level 2: Sample Stored Procedure and Function

As said you have to use SVN Check for modification in GUI and tortoiseproc.exe /command:repostatus /path:"<path-to-version-control-file-or-directory>" in CLI to see changes related to the root of the <path-to-version-control-file-or-directory>.

Sadly, but this command won't show ALL local changes, it does show only those changes which are related to the requested directory root. The changes taken separately, like standalone checkouts or orphan external directories in the root subdirectory will be shown as Unversioned or Nested and you might miss to commit/lookup them.

To avoid such condition you have to either call to tortoiseproc.exe /command:repostatus /pathfile:"<path-to-file-with-list-of-items-to-lookup-from>" (see detailed documentation on the command line: https://tortoisesvn.net/docs/nightly/TortoiseSVN_en/tsvn-automation.html), or use some 3dparty applications/utilities/scripts to wrap the call.

I has been wrote my own set of scripts for Windows to automate the call from the Total Commander: https://sf.net/p/contools/contools/HEAD/tree/trunk/Scripts/Tools/ToolAdaptors/totalcmd/README_EN.txt (search for TortoiseSVN)

- Opens TortoiseSVN status dialog for a set of WC directories (always opens to show unversioned changes).

Command:   call_nowindow.vbs
Arguments: tortoisesvn\TortoiseProcByNestedWC.bat /command:repostatus "%P" %S

- Opens TortoiseSVN commit dialogs for a set of WC directories (opens only if has not empty versioned changes).

Command:   call_nowindow.vbs
Arguments: tortoisesvn\TortoiseProcByNestedWC.bat /command:commit "%P" %S

See the README_EN.txt for the latest details (you have to execute the configure.bat before the usage and copy rest of scripts on yourself like call_nowindow.vbs).

 <input type="text" class="form-control" id="odometer_reading" name="odometer_reading"  placeholder="Odometer Reading" onblur="odometer_reading1();" onkeypress='validate(event)' required="" />
<script>
                function validate(evt) {
                  var theEvent = evt || window.event;
                  var key = theEvent.keyCode || theEvent.which;
                  key = String.fromCharCode( key );
                  var regex = /[0-9]|\./;
                  if( !regex.test(key) ) {
                    theEvent.returnValue = false;
                    if(theEvent.preventDefault) theEvent.preventDefault();
                  }
                }
            </script>

If you want to pause the program to take screenshots of the progress

(shown in let's say cv2.imshow)

cv2.waitKey(0) would continue after pressing "Scr" button (or its combination), but you can try this

cv2.waitKey(0)
input('')

cv2.waitkey(0) to give the program enough time to process everything you want to see in the imshow and input('')

to make it wait for you to press Enter in the console window

this works on python 3

List<String[]> addresses = new ArrayList<String[]>();
String[] addressesArr  = new String[3];

addressesArr[0] = "zero";
addressesArr[1] = "one";
addressesArr[2] = "two";

addresses.add(addressesArr);

Please try this code:

$("#YourSelect>option:selected").html()

The first line of your code returns an array and assigns it to the var comment, when what you want is an element assigned to the var comment...

var comment = document.getElementsByClassName("button");

So you are trying to use the method addEventListener() on the array when you need to use the method addEventListener() on the actual element within the array. You need to return an element not an array by accessing the element within the array so the var comment itself is assigned an element not an array.

Change...

var comment = document.getElementsByClassName("button");

to...

var comment = document.getElementsByClassName("button")[0];

Set the max allowed packet size using MySql Workbench and restart the server

You can do it on one line of code (without array declaration):

object[] someArray = new object[] 
{
    "aaaa",
    3,
    null
};
bool containsSomeNull = someArray.Any(x => x == null);

Just use border-collapse: collapse for your table, and padding for th or td.

I have a search form with an icon that clears the text when clicked. However, the problem (on mobile & tablets) was that the keyboard would collapse/hide, as the click event removed focus was removed from the input.

Goal: after clearing the search form (clicking/tapping on x-icon) keep the keyboard visible!

To accomplish this, apply stopPropagation() on the event like so:

function clear ($event) {
    $event.preventDefault();
    $event.stopPropagation();
    self.query = '';
    $timeout(function () {
        document.getElementById('sidebar-search').focus();
    }, 1);
}

And the HTML form:

<form ng-controller="SearchController as search"
    ng-submit="search.submit($event)">
        <input type="search" id="sidebar-search" 
            ng-model="search.query">
                <span class="glyphicon glyphicon-remove-circle"
                    ng-click="search.clear($event)">
                </span>
</form>

Regarding client timeouts and the use of XACT_ABORT to handle them, in my opinion there is at least one very good reason to have timeouts in client APIs like SqlClient, and that is to guard the client application code from deadlocks occurring in SQL server code. In this case the client code has no fault, but has to protect it self from blocking forever waiting for the command to complete on the server. So conversely, if client timeouts have to exist to protect client code, so does XACT_ABORT ON has to protect server code from client aborts, in case the server code takes longer to execute than the client is willing to wait for.

There's always a problem accessing files on your file directory from a jar file. Providing the classpath in a jar file is very limited. Instead try using a bat file or a sh file to start your program. In that way you can specify your classpath anyway you like, referencing any folder anywhere on the system.

Also check my answer on this question:

Yes, you can run commands on the Ansible host. You can specify that all tasks in a play run on the Ansible host, or you can mark individual tasks to run on the Ansible host.

If you want to run an entire play on the Ansible host, then specify hosts: 127.0.0.1 and connection:local in the play, for example:

- name: a play that runs entirely on the ansible host
  hosts: 127.0.0.1
  connection: local
  tasks:
  - name: check out a git repository
    git: repo=git://foosball.example.org/path/to/repo.git dest=/local/path

See Local Playbooks in the Ansible documentation for more details.

If you just want to run a single task on your Ansible host, you can use local_action to specify that a task should be run locally. For example:

- name: an example playbook
  hosts: webservers
  tasks:
  - ...

  - name: check out a git repository
    local_action: git repo=git://foosball.example.org/path/to/repo.git dest=/local/path

See Delegation in the Ansible documentation for more details.

Edit: You can avoid having to type connection: local in your play by adding this to your inventory:

localhost ansible_connection=local

(Here you'd use "localhost" instead of "127.0.0.1" to refer to the play).

Edit: In newer versions of ansible, you no longer need to add the above line to your inventory, ansible assumes it's already there.

You may also use --keyid-format switch to show short or long key ID:

$ gpg2 -n --with-fingerprint --keyid-format=short --show-keys <filename>

which outputs like this (example from PostgreSQL CentOS repo key):

pub   dsa1024/442DF0F8 2008-01-08 [SCA]                                                                       ¦
      Key fingerprint = 68C9 E2B9 1A37 D136 FE74  D176 1F16 D2E1 442D F0F8                                    ¦              honor-keyserver-url
uid                    PostgreSQL RPM Building Project <[email protected]>                      ¦                     When  using --refresh-keys, if the key in question has a preferred keyserver URL, then use that
sub   elg2048/D43F1AF8 2008-01-08 [E]

Also, don't forget you need to add "-Xdebug" flag in app JAVA_OPTS if you want connect in debug mode.

The copy() runs for the least length of dst and src, so you must initialize the dst to the desired length.

A := []int{1, 2, 3}
B := make([]int, 3)
copy(B, A)
C := make([]int, 2)
copy(C, A)
fmt.Println(A, B, C)

Output:

[1 2 3] [1 2 3] [1 2]

You can initialize and copy all elements in one line using append() to a nil slice.

x := append([]T{}, []...)

Example:

A := []int{1, 2, 3}
B := append([]int{}, A...)
C := append([]int{}, A[:2]...)
fmt.Println(A, B, C)    

Output:

[1 2 3] [1 2 3] [1 2]

Comparing with allocation+copy(), for greater than 1,000 elements, use append. Actually bellow 1,000 the difference may be neglected, make it a go for rule of thumb unless you have many slices.

URL rewriting could be used to map a URL to .php files. The following rules can identify whether a .php request was made directly or it was re-written. It forbids the request in the first case:

RewriteEngine On
RewriteCond %{THE_REQUEST} ^.+?\ [^?]+\.php[?\ ]
RewriteRule \.php$ - [F]
RewriteRule test index.php

These rules will forbid all requests that end with .php. However, URLs such as / (which fires index.php), /test (which rewrites to index.php) and /test?f=index.php (which contains index.php in querystring) are still allowed.

THE_REQUEST contains the full HTTP request line sent by the browser to the server (e.g., GET /index.php?foo=bar HTTP/1.1)

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

As you have found out there is no such thing as a single "local IP address". Here's how to find out the local address that can be sent out to a specific host.

1. Create a UDP socket
2. Connect the socket to an outside address (the host that will eventually receive the local address)
3. Use getsockname to get the local address

Since Java 8 you can use the argument-less any method and the type argument will get inferred by the compiler:

verify(bar).doStuff(any());

Explanation

The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only arguments to methods where used for type parameter inference (most of the time).

In this case the parameter type of doStuff will be the target type for any(), and the return value type of any() will get chosen to match that argument type.

This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.

Primitive types

This doesn't work with primitive types, unfortunately:

public interface IBar {
    void doPrimitiveStuff(int i);
}

verify(bar).doPrimitiveStuff(any()); // Compiles but throws NullPointerException
verify(bar).doPrimitiveStuff(anyInt()); // This is what you have to do instead

The problem is that the compiler will infer Integer as the return value type of any(). Mockito will not be aware of this (due to type erasure) and return the default value for reference types, which is null. The runtime will try to unbox the return value by calling the intValue method on it before passing it to doStuff, and the exception gets thrown.

         select date 'now()' - date '1955-12-15';

Here is the simple query which calculates total no of days.

If you have a look at MySQL Improved Extension Overview, it should tell you everything you need to know about the differences between the two.

The main useful features are:

• an Object-oriented interface
• support for prepared statements
• support for multiple statements
• support for transactions
• enhanced debugging capabilities
• embedded server support.

Any unit test you could create by just pressing a button would not be worth anything. How is the tool to know what parameters to pass your method and what to expect back? Unless I'm misunderstanding your expectations.

Close to that is something like FitNesse, where you can set up tests, then separately you set up a wiki page with your test data, and it runs the tests with that data, publishing the results as red/greens.

If you would be happy to make test writing much faster, I would suggest Mockito, a mocking framework that lets you very easily mock the classes around the one you're testing, so there's less setup/teardown, and you know you're really testing that one class instead of a dependent of it.

Just convert it to a date using NSDateFormatter and the "h:mm a" format and convert it back to a string using the "HH:mm" format. Check out this date formatting guide to familiarize yourself with this material.

let dateAsString = "6:35 PM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "h:mm a"
let date = dateFormatter.dateFromString(dateAsString)

dateFormatter.dateFormat = "HH:mm"
let date24 = dateFormatter.stringFromDate(date!)

I was facing this issue in eclipse . What I did was, killed the running java process from the task manager.

It worked for me.

This is more for someone Searching for a result, than the original post-er. This worked for me...

declare @value varchar(max) = 'sad';
select sum(cast(iif(isnumeric(@value) = 1, @value, 0) as bigint));

returns 0

declare @value varchar(max) = '3';
select sum(cast(iif(isnumeric(@value) = 1, @value, 0) as bigint));

returns 3

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

The first thing you should do with date variables is confirm that R reads it as a Date. To do this, for the variable (i.e. vector/column) called Date, in the data frame called EPL2011_12, input

class(EPL2011_12$Date)

The output should read [1] "Date". If it doesn't, you should format it as a date by inputting

EPL2011_12$Date <- as.Date(EPL2011_12$Date, "%d-%m-%y")

Note that the hyphens in the date format ("%d-%m-%y") above can also be slashes ("%d/%m/%y"). Confirm that R sees it as a Date. If it doesn't, try a different formatting command

EPL2011_12$Date <- format(EPL2011_12$Date, format="%d/%m/%y")

Once you have it in Date format, you can use the subset command, or you can use brackets

WhateverYouWant <- EPL2011_12[EPL2011_12$Date > as.Date("2014-12-15"),]

For some components, it is easier to use inline styles. Also, I find it easier and more concise (as I'm using Javascript and not CSS) to animate component styles.

For stand-alone components, I use the 'Spread Operator' or the '...'. For me, it's clear, beautiful, and works in a tight space. Here is a little loading animation I made to show it's benefits:

<div style={{...this.styles.container, ...this.state.opacity}}>
    <div style={{...this.state.colors[0], ...this.styles.block}}/>
    <div style={{...this.state.colors[1], ...this.styles.block}}/>
    <div style={{...this.state.colors[2], ...this.styles.block}}/>
    <div style={{...this.state.colors[7], ...this.styles.block}}/>
    <div style={{...this.styles.block}}/>
    <div style={{...this.state.colors[3], ...this.styles.block}}/>
    <div style={{...this.state.colors[6], ...this.styles.block}}/>
    <div style={{...this.state.colors[5], ...this.styles.block}}/>
    <div style={{...this.state.colors[4], ...this.styles.block}}/>
  </div>

    this.styles = {
  container: {
    'display': 'flex',
    'flexDirection': 'row',
    'justifyContent': 'center',
    'alignItems': 'center',
    'flexWrap': 'wrap',
    'width': 21,
    'height': 21,
    'borderRadius': '50%'
  },
  block: {
    'width': 7,
    'height': 7,
    'borderRadius': '50%',
  }
}
this.state = {
  colors: [
    { backgroundColor: 'red'},
    { backgroundColor: 'blue'},
    { backgroundColor: 'yellow'},
    { backgroundColor: 'green'},
    { backgroundColor: 'white'},

EDIT NOVEMBER 2019

Working in the industry (A Fortune 500 company), I am NOT allowed to make any inline styling. In our team, we've decided that inline style are unreadable and not maintainable. And, after having seen first hand how inline styles make supporting an application completely intolerable, I'd have to agree. I completely discourage inline styles.

Client validation issues can occur because of MVC bug (even in MVC 5) in jquery.validate.unobtrusive.min.js which does not accept date/datetime format in any way. Unfortunately you have to solve it manually.

My finally working solution:

$(function () {
    $.validator.methods.date = function (value, element) {
        return this.optional(element) || moment(value, "DD.MM.YYYY", true).isValid();
    }
});

You have to include before:

@Scripts.Render("~/Scripts/jquery-3.1.1.js")
@Scripts.Render("~/Scripts/jquery.validate.min.js")
@Scripts.Render("~/Scripts/jquery.validate.unobtrusive.min.js")
@Scripts.Render("~/Scripts/moment.js")

You can install moment.js using:

Install-Package Moment.js

Absolutely valid.

    <form action="javascript:alert('Hello there, I am being submitted');">
        <button type="submit">
            Let's do it
        </button>
    </form>
    <!-- Tested in Firefox, Chrome, Edge and Safari -->

So for a short answer: yes, this is an option, and a nice one. It says "when submitted, please don't go anywhere, just run this script" - quite to the point.

A minor improvement

To let the event handler know which form we're dealing with, it would seem an obvious way to pass on the sender object:

    <form action="javascript:myFunction(this)">  <!-- should work, but it won't -->

But instead, it will give you undefined. You can't access it because javascript: links live in a separate scope. Therefore I'd suggest the following format, it's only 13 characters more and works like a charm:

    <form action="javascript:;" onsubmit="myFunction(this)">  <!-- now you have it! -->

... now you can access the sender form properly. (You can write a simple "#" as action, it's quite common - but it has a side effect of scrolling to the top when submitting.)

Again, I like this approach because it's effortless and self-explaining. No "return false", no jQuery/domReady, no heavy weapons. It just does what it seems to do. Surely other methods work too, but for me, this is The Way Of The Samurai.

A note on validation

Forms only get submitted if their onsubmit event handler returns something truthy, so you can easily run some preemptive checks:

    <form action="/something.php" onsubmit="return isMyFormValid(this)">

Now isMyFormValid will run first, and if it returns false, server won't even be bothered. Needless to say, you will have to validate on server side too, and that's the more important one. But for quick and convenient early detection this is fine.

UPDATED since this was last downvoted....

I only saw the portion

var dots = 5
function increase(){
    dots = dots+5;
}

before, but it was later shown to me that the txt box feeds the variable dots. Because of this, you will need to be sure to "cleanse" the input, to be sure it only has integers, and not malicious code.

One easy way to do this is to parse the textbox with an onkeyup() event to ensure it has numeric characters:

<input size="40" id="txt" value="Write a character here!" onkeyup="GetChar (event);"/>

where the event would give an error and clear the last character if the value is not a number:

<script type="text/javascript">
    function GetChar (event){
        var keyCode = ('which' in event) ? event.which : event.keyCode;
        var yourChar = String.fromCharCode();
        if (yourChar != "0" &&
            yourChar != "1" &&
            yourChar != "2" &&
            yourChar != "3" && 
            yourChar != "4" &&
            yourChar != "5" &&
            yourChar != "6" && 
            yourChar != "7" &&
            yourChar != "8" && 
            yourChar != "9")
        {
            alert ('The character was not a number');
            var source = event.target || event.srcElement;
            source.value = source.value.substring(0,source.value-2);
        }
    }
</script>

Obviously you could do that with regex, too, but I took the lazy way out.

Since then you would know that only numbers could be in the box, you should be able to just use eval():

dots = eval(dots) + 5;

Kotlin for XML

app:cardBackgroundColor="@android:color/red"

code

cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));

There's nothing wrong with include file in head. It seems you forgot to add;. Please try this one:

<body onload="imageRefreshBig();">

But as per my knowledge semicolons are optional. You can try with ; but better debug code and see if chrome console gives any error.

I hope this helps.

I've done this with a T4 template. It is fairly trivial to drop a .tt file into your project, and set up Visual Studio to run the T4 template as a pre-build step.

The T4 generates a .cs file, which means you can have it just query the database and build an enum in a .cs file from the result. Wired up as a pre-build task, it would re-create your enum on every build, or you can run the T4 manually as needed instead.

The best you are going to be able to do for now is create an array with an initial count repeating nil:

var sprites = [SKSpriteNode?](count: 64, repeatedValue: nil)

You can then fill in whatever values you want.

In Swift 3.0 :

var sprites = [SKSpriteNode?](repeating: nil, count: 64)

You need to make sure that a mac compatible version of java exists on your computer. Do java -version from terminal to check that. If not, download the apple jdk from the apple website. (Sun doesn't make one for apple themselves, IIRC.)

From there, follow the same command line instructions from compiling your program that you would use for java on any other platform.

I think what you are looking for is

Request.QueryString["QueryStringName"]

and you can access it on views by adding @

now look at my example,,, I generated a Url with QueryString

 var listURL = '@Url.RouteUrl(new { controller = "Sector", action = "List" , name = Request.QueryString["name"]})';

the listURL value is /Sector/List?name=value'

and when queryString is empty

listURL value is /Sector/List

I think the simplest way might be:

values.reduce(function(a, b){return a+b;})

I checked many solutions and anyone wasn't working good.

So I tried a small trick and it works:

tfoot with style:position: fixed; bottom: 0px; is placed at the bottom of last page, but if footer is too high it is overlapped by content of table.

tfoot with only: display: table-footer-group; isn't overlapped, but is not on the bottom of last page...

Let's put two tfoot:

TFOOT.placer {_x000D_
  display: table-footer-group;_x000D_
  height: 130px;_x000D_
}_x000D_
_x000D_
TFOOT.contenter {_x000D_
  display: table-footer-group;_x000D_
  position: fixed;_x000D_
  bottom: 0px; _x000D_
  height: 130px;_x000D_
}

<TFOOT  class='placer'> _x000D_
  <TR>_x000D_
    <TD>_x000D_
      <!--  empty here_x000D_
-->_x000D_
    </TD>_x000D_
  </TR>_x000D_
</TFOOT> _x000D_
<TFOOT  class='contenter'> _x000D_
  <TR>_x000D_
    <TD>_x000D_
      your long text or high image here_x000D_
    </TD>_x000D_
  </TR>_x000D_
</TFOOT>

One reserves place on non-last pages, second puts in your accual footer.

Use a couple of functions and a boolean. Here's a pattern, not full code:

 var state = false,
     oddONes = function () {...},
     evenOnes = function() {...};

 $("#time").click(function(){
     if(!state){
        evenOnes();
     } else {
        oddOnes();
     }
     state = !state;
  });

Or

  var cases[] = {
      function evenOnes(){...},  // these could even be anonymous functions
      function oddOnes(){...}    // function(){...}
  };

  var idx = 0; // should always be 0 or 1

  $("#time").click(function(idx){cases[idx = ((idx+1)%2)]()}); // corrected

(Note the second is off the top of my head and I mix languages a lot, so the exact syntax isn't guaranteed. Should be close to real Javascript through.)

You can always use Hash#key? to check if the key is present in a hash or not.

If not it will return you false

hash =  { one: 1, two:2 }

hash.key?(:one)
#=> true

hash.key?(:four)
#=> false

Good question.

Here's a simple example based on GHZ's which might help someone:

>>> class person(object):
        def init(self,name):
            self.name=name
        def info(self)
            print "My name is {0}, I am a {1}".format(self.name,self.__class__.__name__)
>>> bob = person(name='Robert')
>>> bob.info()
My name is Robert, I am a person

An alternative approach, which I've recently implemented, is to use the div-table plugin with panflute.

This creates a table from a set of fenced divs (standard in the pandoc implementation of markdown), in a similar layout to html:

---
panflute-filters: [div-table]
panflute-path: 'panflute/docs/source'
---

::::: {.divtable}
:::: {.tcaption}
a caption here (optional), only the first paragraph is used.
::::
:::: {.thead}
[Header 1]{width=0.4 align=center}
[Header 2]{width=0.6 align=default}
::::
:::: {.trow}
::: {.tcell}

1. any
2. normal markdown
3. can go in a cell

:::
::: {.tcell}
![](https://pixabay.com/get/e832b60e2cf7043ed1584d05fb0938c9bd22ffd41cb2144894f9c57aae/bird-1771435_1280.png?attachment){width=50%}

some text
:::
::::
:::: {.trow bypara=true}
If bypara=true

Then each paragraph will be treated as a separate column
::::
any text outside a div will be ignored
:::::

Looks like:

I encountered this issue by putting a XML file into the src/main/resources wrongly, I deleted it and then all back to normal.

For example, to execute following with command prompt or BATCH file we can use this:

C:\Python27\python.exe "C:\Program files(x86)\dev_appserver.py" --host 0.0.0.0 --post 8080 "C:\blabla\"

Same thing to do with Python, we can do this:

subprocess.Popen(['C:/Python27/python.exe', 'C:\\Program files(x86)\\dev_appserver.py', '--host', '0.0.0.0', '--port', '8080', 'C:\\blabla'], shell=True)

or

subprocess.Popen(['C:/Python27/python.exe', 'C:/Program files(x86)/dev_appserver.py', '--host', '0.0.0.0', '--port', '8080', 'C:/blabla'], shell=True)

for Z score, we can stick to documentation instead of using 'apply' function

from scipy.stats import zscore
df_zscore = zscore(cols as array, axis=1)

If you need an easier way to do it, and don't want much fuss, a simple execution could be:

raise Exception.new('something bad happened!')

This will raise an exception, say e with e.message = something bad happened!

and then you can rescue it as you are rescuing all other exceptions in general.

BitConverter.GetBytes(int) almost does what you want, except the endianness is wrong.

You can use the IPAddress.HostToNetwork method to swap the bytes within the the integer value before using BitConverter.GetBytes or use Jon Skeet's EndianBitConverter class. Both methods do the right thing(tm) regarding portability.

int value;
byte[] bytes = BitConverter.GetBytes(IPAddress.HostToNetworkOrder(value));

Instead of gdb, run gdbtui. Or run gdb with the -tui switch. Or press C-x C-a after entering gdb. Now you're in GDB's TUI mode.

Enter layout asm to make the upper window display assembly -- this will automatically follow your instruction pointer, although you can also change frames or scroll around while debugging. Press C-x s to enter SingleKey mode, where run continue up down finish etc. are abbreviated to a single key, allowing you to walk through your program very quickly.

With the help of css you will disable the hyperlink. Try the below

a.disabled {_x000D_
  pointer-events: none;_x000D_
  cursor: default;_x000D_
}

<a href="link.html" class="disabled">Link</a>

In my case, even after sign up to Visual Studio account, I cant sign in and the license still expired.

Solution from across the internet: Download iso version of the installer. Then run installer, select repair. That would solve the problem for most case.

In my case, I got an iso version of ms Visual Studio 2013. Installed it and I can successfully sign in and its forever free.

The way I see it, the only place for a nested query would be in the WHERE clause, so e.g.

SELECT country.name, country.headofstate
FROM country 
WHERE country.headofstate LIKE 'A%' AND 
country.id in (SELECT country_id FROM city WHERE population > 100000)

Apart from that, I have to agree with Adrian on: why the heck should you use nested queries?

Polymorphism: Suppose you work for a company that sells pens. So you make a very nice class called "Pen" that handles everything that you need to know about a pen. You write all sorts of classes for billing, shipping, creating invoices, all using the Pen class. A day boss comes and says, "Great news! The company is growing and we are selling Books & CD's now!" Not great news because now you have to change every class that uses Pen to also use Book & CD. But what if you had originally created an interface called "SellableProduct", and Pen implemented this interface. Then you could have written all your shipping, invoicing, etc classes to use that interface instead of Pen. Now all you would have to do is create a new class called Book & CompactDisc which implements the SellableProduct interface. Because of polymorphism, all of the other classes could continue to work without change! Make Sense?

So, it means using Inheritance which is one of the way to achieve polymorphism.

Polymorhism can be possible in a class / interface but Inheritance always between 2 OR more classes / interfaces. Inheritance always conform "is-a" relationship whereas it is not always with Polymorphism (which can conform both "is-a" / "has-a" relationship.

serialize all the form-elements within a div.

You could do that by targeting the div #target-div-id inside your form using :

$('#target-div-id').find('select, textarea, input').serialize();

Easier solution will be changing this line

ft.replace(R.id.content_frame, A); to ft.add(R.id.content_frame, A);

And inside your XML layout please use

  android:background="@color/white"
  android:clickable="true"
  android:focusable="true"

Clickable means that it can be clicked by a pointer device or be tapped by a touch device.

Focusable means that it can gain the focus from an input device like a keyboard. Input devices like keyboards cannot decide which view to send its input events to based on the inputs itself, so they send them to the view that has focus.

I had this problem recently and the problem was that my web server was not configured to serve woff files. For IIS 7, you can select your site, then select the MIME Types icon. If .woff is not in the list, you need to add it. The correct values are

File name extension: .woff
MIME type: application/font-woff

What worked for me:

Package Manager Console (Visual Studio 2019 Comunity):

Install-Package NuGet.CommandLine
nuget locals all -clear

Rebuild solution.

1. You can also achieve this using the backreference technique

   sed -i.bak 's/\(.*\)/prefix\1/' foo.txt
   

2. You can also use with awk like this

   awk '{print "prefix"$0}' foo.txt > tmp && mv tmp foo.txt
   

public class initials {

public static void main (String [] args) {

    char initialA = 'M';
    char initialB = 'P';
    char initialC = 'T';

    System.out.println("" + initialA + initialB + initialC );


}   

}

The better option is create a new table copy the rows to the destination table, drop the actual table and rename the newly created table . This method is good for small tables,

A command that would copy in any case

xcopy "path\source" "path\destination" /s/h/e/k/f/c/y

Go to Start > Programs > Microsoft SQL Server > Enterprise Manager

Right-click the SQL Server instance name > Select Properties from the context menu > Select Security node in left navigation bar

Under Authentication section, select SQL Server and Windows Authentication

Note: The server must be stopped and re-started before this will take effect

Error 18452 (not associated with a trusted sql server connection)

It is enough to use in your xml file.

android:singleLine="false".

Hope it will work.

All the best!

I had a similar problem using android 5.0 with a bad parent activity name

<activity
        android:name=".DisplayMessageActivity"
        android:label="@string/title_activity_display_message"
        android:parentActivityName=".MainActivity" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.myfirstapp.MainActivity" />
    </activity>

I removed the com.example.myfirstapp from the parent activity name and it worked properly

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

class Dad
{
    protected static String me = "dad";

    public void printMe()
    {
        System.out.println(me);
    }
}

class Son extends Dad
{
    protected static String _me = me = "son";
}

public void doIt()
{
    new Son().printMe();
}

... will print "son".

A quick google pointed me to this page. It explains that from sql server 2005 onwards you can set the default schema of a user with the ALTER USER statement. Unfortunately, that means that you change it permanently, so if you need to switch between schemas, you would need to set it every time you execute a stored procedure or a batch of statements. Alternatively, you could use the technique described here.

If you are using sql server 2000 or older this page explains that users and schemas are then equivalent. If you don't prepend your table name with a schema\user, sql server will first look at the tables owned by the current user and then the ones owned by the dbo to resolve the table name. It seems that for all other tables you must prepend the schema\user.

<video id="myvideo">
  <source src="path/to/movie.mp4" />
</video>

<p onclick="toggleControls();">Toggle</p>

<script>
var video = document.getElementById("myvideo");

function toggleControls() {
  if (video.hasAttribute("controls")) {
     video.removeAttribute("controls")   
  } else {
     video.setAttribute("controls","controls")   
  }
}
</script>

See it working on jsFiddle: http://jsfiddle.net/dgLds/

If you use RxAndroid then thread and error handling becomes much easier. Following code executes after a delay

   Observable.timer(delay, TimeUnit.SECONDS)
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(aLong -> {
           // Execute code here
        }, Throwable::printStackTrace);

You might be looking for IgnoreDataMemberAttribute.

for name in mydict:
    if mydict[name] == search_age:
        print(name) 
        #or do something else with it. 
        #if in a function append to a temporary list, 
        #then after the loop return the list

You could try using AJAX calls with jQuery. Like how youtube adds your comment without refreshing. This would remove the problem with refreshing overal.

You'd need to send the info necessary trough the ajax call.
I'll use the youtube comment as example.

$.ajax({
    type: 'POST',
    url: 'ajax/comment-on-video.php',
    data: {
        comment: $('#idOfInputField').val();
     },
    success: function(obj) {
        if(obj === 'true') {
            //Some code that recreates the inserted comment on the page.
        }
    }
});

You can now create the file comment-on-video.php and create something like this:

<?php
    session_start();

    if(isset($_POST['comment'])) {
        $comment = mysqli_real_escape_string($db, $_POST['comment']);
        //Given you are logged in and store the user id in the session.
        $user = $_SESSION['user_id'];

        $query = "INSERT INTO `comments` (`comment_text`, `user_id`) VALUES ($comment, $user);";
        $result = mysqli_query($db, $query);

        if($result) {
            echo true;
            exit();
        }
    }
    echo false;
    exit();
?>

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

use auto and min or max width like this:

td {
max-width:50px;
width:auto;
min-width:10px;
}

Like this ?

<script>
var meta = document.createElement('meta');
meta.setAttribute('http-equiv', 'X-UA-Compatible');
meta.setAttribute('content', 'IE=Edge');
document.getElementsByTagName('head')[0].appendChild(meta);
</script>

This is from the lovely JavaScript library MooTools:

if (obj.nodeName){
    switch (obj.nodeType){
    case 1: return 'element';
    case 3: return (/\S/).test(obj.nodeValue) ? 'textnode' : 'whitespace';
    }
}

Since Java 8 new feature Optional you should not use @Nullable or @Notnull in your own code anymore. Take the example below:

public void printValue(@Nullable myValue) {
    if (myValue != null) {
        System.out.print(myValue);
    } else {
        System.out.print("I dont have a value");
}

It could be rewritten with:

public void printValue(Optional<String> myValue) {
    if (myValue.ifPresent) {
        System.out.print(myValue.get());
    } else {
        System.out.print("I dont have a value");
}

Using an optional forces you to check for null value. In the code above, you can only access the value by calling the get method.

Another advantage is that the code get more readable. With the addition of Java 9 ifPresentOrElse, the function could even be written as:

public void printValue(Optional<String> myValue) {
    myValue.ifPresentOrElse(
        v -> System.out.print(v),
        () -> System.out.print("I dont have a value"),
    )
}

Use ISNULL(field, 0) It can also be used with aggregates:

ISNULL(count(field), 0)

However, you might consider changing count(field) to count(*)

Edit:

try:

closedcases = ISNULL(
   (select count(closed) from ticket       
    where assigned_to = c.user_id and closed is not null       
    group by assigned_to), 0), 

opencases = ISNULL(
    (select count(closed) from ticket 
     where assigned_to = c.user_id and closed is null 
     group by assigned_to), 0),

Back references can find interesting solutions here. This regex:

([a-z]+).*(\1)

will find the longest repeated sequence.

This one will find a sequence of 3 letters that is repeated:

([a-z]{3}).*(\1)

How about this:

UPDATE p
SET p.extrasPrice = t.sumPrice
FROM BookingPitches AS p
INNER JOIN
    (
        SELECT PitchID, SUM(Price) sumPrice
        FROM BookingPitchExtras
        WHERE [required] = 1
        GROUP BY PitchID 
    ) t
    ON t.PitchID = p.ID
WHERE p.bookingID = 1

If you have separated files for angular app\resources\directives and other stuff then you can just disable minification of your angular app bundle like this (use new Bundle() instead of ScriptBundle() in your bundle config file):

I'm working in a legacy codebase trying to migrate to Vue.

In my specific situation (scrollable div wrapped in a bootstrap modal), a v-if showed new content, which I wanted the page to scroll down to. In order to get this behaviour to work, I had to wait for vue to finish re-rendering, and then use jQuery to scroll to the bottom of the modal.

So...

this.$nextTick(function() {
    $('#thing')[0].scrollTop = $('#thing')[0].scrollHeight;
})

int numberOfSpaces = 3;
String space = String.format("%"+ numberOfSpaces +"s", " ");

The solution by @virgo47 is very fast, but approximate. The accepted answer uses Normalizer and a regular expression. I wondered what part of the time was taken by Normalizer versus the regular expression, since removing all the non-ASCII characters can be done without a regex:

import java.text.Normalizer;

public class Strip {
    public static String flattenToAscii(String string) {
        StringBuilder sb = new StringBuilder(string.length());
        string = Normalizer.normalize(string, Normalizer.Form.NFD);
        for (char c : string.toCharArray()) {
            if (c <= '\u007F') sb.append(c);
        }
        return sb.toString();
    }
}

Small additional speed-ups can be obtained by writing into a char[] and not calling toCharArray(), although I'm not sure that the decrease in code clarity merits it:

public static String flattenToAscii(String string) {
    char[] out = new char[string.length()];
    string = Normalizer.normalize(string, Normalizer.Form.NFD);
    int j = 0;
    for (int i = 0, n = string.length(); i < n; ++i) {
        char c = string.charAt(i);
        if (c <= '\u007F') out[j++] = c;
    }
    return new String(out);
}

This variation has the advantage of the correctness of the one using Normalizer and some of the speed of the one using a table. On my machine, this one is about 4x faster than the accepted answer, and 6.6x to 7x slower that @virgo47's (the accepted answer is about 26x slower than @virgo47's on my machine).

There is a way to catch the error directly in the except clause with ConnectionResetError, better to isolate the right error. This example also catches the timeout.

from urllib.request import urlopen 
from socket import timeout

url = "http://......"
try: 
    string = urlopen(url, timeout=5).read()
except ConnectionResetError:
    print("==> ConnectionResetError")
    pass
except timeout: 
    print("==> Timeout")
    pass

Should be .\SQLExpress or localhost\SQLExpress no $ sign at the end

What you're doing there is not recursing into directories. It is only listing the modules in the root directory of the @INC directory.

The module XML::Simple will live in one of the @INC paths under XML/Simple.pm.

What he said above to find specific modules.

CPAN explains how to find all modules here, see How to find installed modules.

After many answers that did not work, I finally found a solution when Anonymous access is Disabled on the IIS server. Our server is using Windows authentication, not Kerberos. This is thanks to this blog posting.

No changes were made to web.config.

On the server side, the .SVC file in the ISAPI folder uses MultipleBaseAddressBasicHttpBindingServiceHostFactory

The class attributes of the service are:

[BasicHttpBindingServiceMetadataExchangeEndpointAttribute]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class InvoiceServices : IInvoiceServices
{
...
}

On the client side, the key that made it work was the http binding security attributes:

EndpointAddress endpoint =
  new EndpointAddress(new Uri("http://SharePointserver/_vti_bin/InvoiceServices.svc"));
BasicHttpBinding httpBinding = new BasicHttpBinding();
httpBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
httpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;
InvoiceServicesClient myClient = new InvoiceServicesClient(httpBinding, endpoint);
myClient.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation; 

(call service)

I hope this works for you!

Try this code it is already built in c#

int lastDay = DateTime.DaysInMonth (2014, 2);

and the first day is always 1.

Good Luck!

Delete the file(index.php) from your xampp folder, you will get the list of directories and files from htdocs folder.

function go(type, pageCount) {
    if ((type == 2 && pageCount == 0) || (type == 2 && pageCount == '')) {
        pageCount = document.getElementById('<%=hfPageCount.ClientID %>').value;
    }
}

If you are using post as a model (without dependency injection), you can also do:

$posts = Post::orderBy('id', 'DESC')->get();

If you are using pandas you can access the index by calling .index of whatever array you wish to mimic. The train_test_split carries over the pandas indices to the new dataframes.

In your code you simply use x1.index and the returned array is the indexes relating to the original positions in x.

In the case of determining whether only some keys match, this works:

any_keys_i_seek = ["key1", "key2", "key3"]

if set(my_dict).intersection(any_keys_i_seek):
    # code_here
    pass

Yet another option to find if only some keys match:

any_keys_i_seek = ["key1", "key2", "key3"]

if any_keys_i_seek & my_dict.keys():
    # code_here
    pass

When you talked about "Hash Table will place a new entry into the 'next available' bucket if the new Key entry collides with another.", you are talking about the Open addressing strategy of Collision resolution of hash table.

There are several strategies for hash table to resolve collision.

First kind of big method require that the keys (or pointers to them) be stored in the table, together with the associated values, which further includes:

• Separate chaining

• Open addressing

• Coalesced hashing
• Cuckoo hashing
• Robin Hood hashing
• 2-choice hashing
• Hopscotch hashing

Another important method to handle collision is by Dynamic resizing, which further has several ways:

• Resizing by copying all entries
• Incremental resizing
• Monotonic keys

EDIT: the above are borrowed from wiki_hash_table, where you should go to have a look to get more info.

Hopefully this would get you started

See it live on http://ideone.com/l23He (using stdin)

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

const char* getfield(char* line, int num)
{
    const char* tok;
    for (tok = strtok(line, ";");
            tok && *tok;
            tok = strtok(NULL, ";\n"))
    {
        if (!--num)
            return tok;
    }
    return NULL;
}

int main()
{
    FILE* stream = fopen("input", "r");

    char line[1024];
    while (fgets(line, 1024, stream))
    {
        char* tmp = strdup(line);
        printf("Field 3 would be %s\n", getfield(tmp, 3));
        // NOTE strtok clobbers tmp
        free(tmp);
    }
}

Output:

Field 3 would be nazwisko
Field 3 would be Kowalski
Field 3 would be Nowak

This problem usually occurs while cloning large repos. If git clone http://github.com/large-repository --depth 1 does not work on windows cmd. Try running the command in windows powershell.

For me, what worked on Windows was running Command Prompt as administrator and then installing pipenv globally: python -m pip install pipenv.

Much simpler: use sudo to run a shell and use a heredoc to feed it commands.

#!/usr/bin/env bash
whoami
sudo -i -u someuser bash << EOF
echo "In"
whoami
EOF
echo "Out"
whoami

This is what we use in ASP.NET:

// Stop Caching in IE
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);

// Stop Caching in Firefox
Response.Cache.SetNoStore();

It stops caching in Firefox and IE, but we haven't tried other browsers. The following response headers are added by these statements:

Cache-Control: no-cache, no-store
Pragma: no-cache

Generics Solution

Here's a generic version of Json converter

package com.github.platform.util;

import java.io.IOException;
import java.lang.reflect.InvocationTargetException;
import com.google.protobuf.AbstractMessage.Builder;
import com.google.protobuf.Message;
import com.google.protobuf.MessageOrBuilder;
import com.google.protobuf.util.JsonFormat;

/**
 * Generic ProtoJsonUtil to be used to serialize and deserialize Proto to json
 * 
 * @author [email protected]
 *
 */
public final class ProtoJsonUtil {

  /**
   * Makes a Json from a given message or builder
   * 
   * @param messageOrBuilder is the instance
   * @return The string representation
   * @throws IOException if any error occurs
   */
  public static String toJson(MessageOrBuilder messageOrBuilder) throws IOException {
    return JsonFormat.printer().print(messageOrBuilder);
  }

  /**
   * Makes a new instance of message based on the json and the class
   * @param <T> is the class type
   * @param json is the json instance
   * @param clazz is the class instance
   * @return An instance of T based on the json values
   * @throws IOException if any error occurs
   */
  @SuppressWarnings({"unchecked", "rawtypes"})
  public static <T extends Message> T fromJson(String json, Class<T> clazz) throws IOException {
    // https://stackoverflow.com/questions/27642021/calling-parsefrom-method-for-generic-protobuffer-class-in-java/33701202#33701202
    Builder builder = null;
    try {
      // Since we are dealing with a Message type, we can call newBuilder()
      builder = (Builder) clazz.getMethod("newBuilder").invoke(null);

    } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException
        | NoSuchMethodException | SecurityException e) {
      return null;
    }

    // The instance is placed into the builder values
    JsonFormat.parser().ignoringUnknownFields().merge(json, builder);

    // the instance will be from the build
    return (T) builder.build();
  }
}

Using it is as simple as follows:

Message instance

GetAllGreetings.Builder allGreetingsBuilder = GetAllGreetings.newBuilder();

allGreetingsBuilder.addGreeting(makeNewGreeting("Marcello", "Hi %s, how are you", Language.EN))
        .addGreeting(makeNewGreeting("John", "Today is hot, %s, get some ice", Language.ES))
        .addGreeting(makeNewGreeting("Mary", "%s, summer is here! Let's go surfing!", Language.PT));

GetAllGreetings allGreetings = allGreetingsBuilder.build();

To Json Generic

String json = ProtoJsonUtil.toJson(allGreetingsLoaded);
log.info("Json format: " + json);

From Json Generic

GetAllGreetings parsed = ProtoJsonUtil.fromJson(json, GetAllGreetings.class);
log.info("The Proto deserialized from Json " + parsed);

try this new DecimalFormat("#.00");

update:

    double angle = 20.3034;

    DecimalFormat df = new DecimalFormat("#.00");
    String angleFormated = df.format(angle);
    System.out.println(angleFormated); //output 20.30

Your code wasn't using the decimalformat correctly

The 0 in the pattern means an obligatory digit, the # means optional digit.

update 2: check bellow answer

If you want 0.2677 formatted as 0.27 you should use new DecimalFormat("0.00"); otherwise it will be .27

doing this shown above...

table tr{ float: left width: 100%; }  tr.classname { margin-bottom:5px; } 

removes vertical column alignment so be careful how you use it

If time_created is a unix timestamp (int), you should be able to use something like this:

DELETE FROM locks WHERE time_created < (UNIX_TIMESTAMP() - 600);

(600 seconds = 10 minutes - obviously)

Otherwise (if time_created is mysql timestamp), you could try this:

DELETE FROM locks WHERE time_created < (NOW() - INTERVAL 10 MINUTE)

I came across another solution here that is so simple: add padding-right to the textarea's container. This keeps the margin, border, and padding on the textarea, which avoids the problem that Beck pointed out about the focus highlight that chrome and safari put around the textarea.

The container's padding-right should be the sum of the effective margin, border, and padding on both sides of the textarea, plus any padding you may otherwise want for the container. So, for the case in the original question:

textarea{
    border:1px solid #999999;
    width:100%;
    margin:5px 0;
    padding:3px;
}
.textareacontainer{
    padding-right: 8px; /* 1 + 3 + 3 + 1 */
}

<div class="textareacontainer">
    <textarea></textarea>
</div>

I was struggling with the same thing, running a shell script that set variables, then wanting to use the variables in the shared-pom. The goal was to have environment variables replace strings in my project files using the com.google.code.maven-replacer-plugin.

Using ${env.foo} or ${env.FOO} didn't work for me. Maven just wasn't finding the variable. What worked was passing the variable in as a command-line parameter in Maven. Here's the setup:

1. Set the variable in the shell script. If you're launching Maven in a sub-script, make sure the variable is getting set, e.g. using source ./maven_script.sh to call it from the parent script.

2. In shared-pom, create a command-line param that grabs the environment variable:

<plugin>
  ...
  <executions>
    <executions>
    ...
      <execution>
      ...
        <configuration>
          <param>${foo}</param> <!-- Note this is *not* ${env.foo} -->
        </configuration>

3. In com.google.code.maven-replacer-plugin, make the replacement value ${foo}.

4. In my shell script that calls maven, add this to the command: -Dfoo=$foo

When everything sounded so complicated, this command worked for me:

keytool -genkey -alias foo -keystore cacerts -dname cn=test -storepass changeit -keypass changeit

When a developer is in trouble, I believe a simple working solution snippet is more than enough for him. Later he could diagnose the root cause and basic understanding related to the issue.

I solved it upgrading the lxml version with:

pip install --upgrade lxml

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

In my case for Bootstrap4:

<body class="d-flex flex-column min-vh-100">
    <div class="wrapper flex-grow-1"></div>
    <footer></footer>
</body>

The above answers are pretty good. My only complaint is that you can't clear the value once it's been set. Also I prefer the extend-jquery-like-a-plugin approach.

This works perfect for me:

$.fn.monthYearPicker = function(options) {
    options = $.extend({
        dateFormat: "MM yy",
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        showAnim: ""
    }, options);
    function hideDaysFromCalendar() {
        var thisCalendar = $(this);
        $('.ui-datepicker-calendar').detach();
        // Also fix the click event on the Done button.
        $('.ui-datepicker-close').unbind("click").click(function() {
            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
            thisCalendar.datepicker('setDate', new Date(year, month, 1));
        });
    }
    $(this).datepicker(options).focus(hideDaysFromCalendar);
}

Then invoke like so:

$('input.monthYearPicker').monthYearPicker();

Here's how I did it in Swift 4.2:

extension Date {

    /// Create a date from specified parameters
    ///
    /// - Parameters:
    ///   - year: The desired year
    ///   - month: The desired month
    ///   - day: The desired day
    /// - Returns: A `Date` object
    static func from(year: Int, month: Int, day: Int) -> Date? {
        let calendar = Calendar(identifier: .gregorian)
        var dateComponents = DateComponents()
        dateComponents.year = year
        dateComponents.month = month
        dateComponents.day = day
        return calendar.date(from: dateComponents) ?? nil
    }
}

Usage:

let marsOpportunityLaunchDate = Date.from(year: 2003, month: 07, day: 07)

You don't really need a sub-select:

SELECT a, COUNT(*) AS b,
   SUM( CASE WHEN c = 'const' THEN 1 ELSE 0 END ) as d,
   from t group by a order by b desc

When your script is run by passing it as a command to the Python interpreter,

python myscript.py

all of the code that is at indentation level 0 gets executed. Functions and classes that are defined are, well, defined, but none of their code gets run. Unlike other languages, there's no main() function that gets run automatically - the main() function is implicitly all the code at the top level.

In this case, the top-level code is an if block. __name__ is a built-in variable which evaluates to the name of the current module. However, if a module is being run directly (as in myscript.py above), then __name__ instead is set to the string "__main__". Thus, you can test whether your script is being run directly or being imported by something else by testing

if __name__ == "__main__":
    ...

If your script is being imported into another module, its various function and class definitions will be imported and its top-level code will be executed, but the code in the then-body of the if clause above won't get run as the condition is not met. As a basic example, consider the following two scripts:

# file one.py
def func():
    print("func() in one.py")

print("top-level in one.py")

if __name__ == "__main__":
    print("one.py is being run directly")
else:
    print("one.py is being imported into another module")

# file two.py
import one

print("top-level in two.py")
one.func()

if __name__ == "__main__":
    print("two.py is being run directly")
else:
    print("two.py is being imported into another module")

Now, if you invoke the interpreter as

python one.py

The output will be

top-level in one.py
one.py is being run directly

If you run two.py instead:

python two.py

You get

top-level in one.py
one.py is being imported into another module
top-level in two.py
func() in one.py
two.py is being run directly

Thus, when module one gets loaded, its __name__ equals "one" instead of "__main__".

nil? can be omitted in boolean contexts. Generally, you can use this to replicate the C# code:

return my_string.nil? || my_string.empty?
