You may want to consider placing the customer's name in the From header and your address in the Sender header:

From: Company A <[email protected]>
Sender: [email protected]

Most mailers will render this as "From [email protected] on behalf of Company A", which is accurate. And then a Reply-To of Company A's address won't seem out of sorts.

From RFC 5322:

The "From:" field specifies the author(s) of the message, that is, the mailbox(es) of the person(s) or system(s) responsible for the writing of the message. The "Sender:" field specifies the mailbox of the agent responsible for the actual transmission of the message. For example, if a secretary were to send a message for another person, the mailbox of the secretary would appear in the "Sender:" field and the mailbox of the actual author would appear in the "From:" field.

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

There are a lot more techniques to factoring than the sieve of Atkin. For example suppose we want to factor 5893. Well its sqrt is 76.76... Now we'll try to write 5893 as a product of squares. Well (77*77 - 5893) = 36 which is 6 squared, so 5893 = 77*77 - 6*6 = (77 + 6)(77-6) = 83*71. If that hadn't worked we'd have looked at whether 78*78 - 5893 was a perfect square. And so on. With this technique you can quickly test for factors near the square root of n much faster than by testing individual primes. If you combine this technique for ruling out large primes with a sieve, you will have a much better factoring method than with the sieve alone.

And this is just one of a large number of techniques that have been developed. This is a fairly simple one. It would take you a long time to learn, say, enough number theory to understand the factoring techniques based on elliptic curves. (I know they exist. I don't understand them.)

Therefore unless you are dealing with small integers, I wouldn't try to solve that problem myself. Instead I'd try to find a way to use something like the PARI library that already has a highly efficient solution implemented. With that I can factor a random 40 digit number like 124321342332143213122323434312213424231341 in about .05 seconds. (Its factorization, in case you wondered, is 29*439*1321*157907*284749*33843676813*4857795469949. I am quite confident that it didn't figure this out using the sieve of Atkin...)

I don't think that notation is available because—unlike say PHP or C—everything in Ruby is an object.

Sure you could use $var=0; $var++ in PHP, but that's because it's a variable and not an object. Therefore, $var = new stdClass(); $var++ would probably throw an error.

I'm not a Ruby or RoR programmer, so I'm sure someone can verify the above or rectify it if it's inaccurate.

As the chosen answer is pretty old, and things changed, here is the new procedure, if you use 64 bits Notepad++. 64 bits version does not come with Plugin Manager nor NppExport. All details provided here.

Here's a simple wrapper for steven's answer. This function doesn't do repeated runs/averaging, just saves you from having to repeat the timing code everywhere :)

'''function which prints the wall time it takes to execute the given command'''
def time_func(func, *args): #*args can take 0 or more 
  import time
  start_time = time.time()
  func(*args)
  end_time = time.time()
  print("it took this long to run: {}".format(end_time-start_time))

I'd like to clarify a few things:

1. As other answers have pointed out, the simplest thing to do is use pandas.Series.tolist(). I'm not sure why the top voted answer leads off with using pandas.Series.values.tolist() since as far as I can tell, it adds syntax/confusion with no added benefit.
2. tst[lookupValue][['SomeCol']] is a dataframe (as stated in the question), not a series (as stated in a comment to the question). This is because tst[lookupValue] is a dataframe, and slicing it with [['SomeCol']] asks for a list of columns (that list that happens to have a length of 1), resulting in a dataframe being returned. If you remove the extra set of brackets, as in tst[lookupValue]['SomeCol'], then you are asking for just that one column rather than a list of columns, and thus you get a series back.
3. You need a series to use pandas.Series.tolist(), so you should definitely skip the second set of brackets in this case. FYI, if you ever end up with a one-column dataframe that isn't easily avoidable like this, you can use pandas.DataFrame.squeeze() to convert it to a series.
4. tst[lookupValue]['SomeCol'] is getting a subset of a particular column via chained slicing. It slices once to get a dataframe with only certain rows left, and then it slices again to get a certain column. You can get away with it here since you are just reading, not writing, but the proper way to do it is tst.loc[lookupValue, 'SomeCol'] (which returns a series).
5. Using the syntax from #4, you could reasonably do everything in one line: ID = tst.loc[tst['SomeCol'] == 'SomeValue', 'SomeCol'].tolist()

Demo Code:

import pandas as pd
df = pd.DataFrame({'colA':[1,2,1],
                   'colB':[4,5,6]})
filter_value = 1

print "df"
print df
print type(df)

rows_to_keep = df['colA'] == filter_value
print "\ndf['colA'] == filter_value"
print rows_to_keep
print type(rows_to_keep)

result = df[rows_to_keep]['colB']
print "\ndf[rows_to_keep]['colB']"
print result
print type(result)

result = df[rows_to_keep][['colB']]
print "\ndf[rows_to_keep][['colB']]"
print result
print type(result)

result = df[rows_to_keep][['colB']].squeeze()
print "\ndf[rows_to_keep][['colB']].squeeze()"
print result
print type(result)

result = df.loc[rows_to_keep, 'colB']
print "\ndf.loc[rows_to_keep, 'colB']"
print result
print type(result)

result = df.loc[df['colA'] == filter_value, 'colB']
print "\ndf.loc[df['colA'] == filter_value, 'colB']"
print result
print type(result)

ID = df.loc[rows_to_keep, 'colB'].tolist()
print "\ndf.loc[rows_to_keep, 'colB'].tolist()"
print ID
print type(ID)

ID = df.loc[df['colA'] == filter_value, 'colB'].tolist()
print "\ndf.loc[df['colA'] == filter_value, 'colB'].tolist()"
print ID
print type(ID)

Result:

df
   colA  colB

df.loc[df['colA'] == filter_value, 'colB']
0    4
2    6
Name: colB, dtype: int64
<class 'pandas.core.series.Series'>

df.loc[rows_to_keep, 'colB'].tolist()
[4, 6]
<type 'list'>

df.loc[df['colA'] == filter_value, 'colB'].tolist()
[4, 6]
<type 'list'>

Note to the above solution (from A Paul): The solution doesn't work, cause it doesn't reconstructs back a HashMap< String, Object > - instead it creates a HashMap< String, LinkedHashMap >.

Reason why is because during demarshalling, each Object (JSON marshalled as a LinkedHashMap) is used as-is, it takes 1-on-1 the LinkedHashMap (instead of converting the LinkedHashMap back to its proper Object).

If you had a HashMap< String, MyOwnObject > then proper demarshalling was possible - see following example:

ObjectMapper mapper = new ObjectMapper();
TypeFactory typeFactory = mapper.getTypeFactory();
MapType mapType = typeFactory.constructMapType(HashMap.class, String.class, MyOwnObject.class);
HashMap<String, MyOwnObject> map = mapper.readValue(new StringReader(hashTable.toString()), mapType);

Sure, the [::] is the extended slice operator. It allows you to take substrings. Basically, it works by specifying which elements you want as [begin:end:step], and it works for all sequences. Two neat things about it:

• You can omit one or more of the elements and it does "the right thing"
• Negative numbers for begin, end, and step have meaning

For begin and end, if you give a negative number, it means to count from the end of the sequence. For instance, if I have a list:

l = [1,2,3]

Then l[-1] is 3, l[-2] is 2, and l[-3] is 1.

For the step argument, a negative number means to work backwards through the sequence. So for a list::

l = [1,2,3,4,5,6,7,8,9,10]

You could write l[::-1] which basically means to use a step size of -1 while reading through the list. Python will "do the right thing" when filling in the start and stop so it iterates through the list backwards and gives you [10,9,8,7,6,5,4,3,2,1].

I've given the examples with lists, but strings are just another sequence and work the same way. So a[::-1] means to build a string by joining the characters you get by walking backwards through the string.

If you need to distniguish between a click, longpress and a scroll use GestureDetector

Activity implements GestureDetector.OnGestureListener

then create detector in onCreate for example

mDetector = new GestureDetectorCompat(getActivity().getApplicationContext(),this);

then optionally setOnTouchListener on your View (for example webview) where

onTouch(View v, MotionEvent event) {
return mDetector.onTouchEvent(event);
}

and now you can use Override onScroll, onFling, showPress( detect long press) or onSingleTapUp (detect a click)

As others wrote before me, at the end its what being used by your project/team/company.

Personally, I am not using cc extension, I am trying to lower the number of extensions and not increase them, unless there's a clear value (in my opinion).

For what its worth, this is what I'm using:

c - Pure C code only, no classes or structs with methods.

cpp - C++ code

hpp - Headers only code. Implementations are in the headers (like template classes)

h - header files for both C/C++. I agree another distinction can be made, but as I wrote, I am trying to lower the number of extensions for simplicity. At least from the C++ projects I've worked in, h files for pure-C are more rare, therefore I did not want to add another extension.

I had the same issue, docker-compose was creating a directory instead of a file, then crashing mid-way.

what i did :

1. run the container without mapping the file

2. copy the config file to the host location :

   docker cp containername:/var/www/html/config.php ./config.php

3. remove the container (docker-compose down)

4. put the mapping back and remount up the container

docker compose will find the config file, and will map that instead of trying to create a directory.

On the contrary, you should always prefer stack allocations, to the extent that as a rule of thumb, you should never have new/delete in your user code.

As you say, when the variable is declared on the stack, its destructor is automatically called when it goes out of scope, which is your main tool for tracking resource lifetime and avoiding leaks.

So in general, every time you need to allocate a resource, whether it's memory (by calling new), file handles, sockets or anything else, wrap it in a class where the constructor acquires the resource, and the destructor releases it. Then you can create an object of that type on the stack, and you're guaranteed that your resource gets freed when it goes out of scope. That way you don't have to track your new/delete pairs everywhere to ensure you avoid memory leaks.

The most common name for this idiom is RAII

Also look into smart pointer classes which are used to wrap the resulting pointers on the rare cases when you do have to allocate something with new outside a dedicated RAII object. You instead pass the pointer to a smart pointer, which then tracks its lifetime, for example by reference counting, and calls the destructor when the last reference goes out of scope. The standard library has std::unique_ptr for simple scope-based management, and std::shared_ptr which does reference counting to implement shared ownership.

Many tutorials demonstrate object instantiation using a snippet such as ...

So what you've discovered is that most tutorials suck. ;) Most tutorials teach you lousy C++ practices, including calling new/delete to create variables when it's not necessary, and giving you a hard time tracking lifetime of your allocations.

This is fairly easy to answer from the internet. Set system properties http.proxyHost and http.proxyPort. You can do this with System.setProperty(), or from the command line with the -D syntax.

Simple INNER JOIN VIEW code....

CREATE VIEW room_view
AS SELECT a.*,b.*
FROM j4_booking a INNER JOIN j4_scheduling b
on a.room_id = b.room_id;

Using foreach loop without key

foreach($array as $item) {
    echo $item['filename'];
    echo $item['filepath'];

    // to know what's in $item
    echo '<pre>'; var_dump($item);
}

Using foreach loop with key

foreach($array as $i => $item) {
    echo $item[$i]['filename'];
    echo $item[$i]['filepath'];

    // $array[$i] is same as $item
}

Using for loop

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

var_dump is a really useful function to get a snapshot of an array or object.

I was able to make parent window disable. However making the pop-up always keep raised didn't work. Below code works even for frame tags. Just add id and class property to frame tag and it works well there too.

In parent window use:

<head>    
<style>
.disableWin{
     pointer-events: none;
}
</style>
<script type="text/javascript">
    function openPopUp(url) {
      disableParentWin(); 
      var win = window.open(url);
      win.focus();
      checkPopUpClosed(win);
    }
    /*Function to detect pop up is closed and take action to enable parent window*/
   function checkPopUpClosed(win) {
         var timer = setInterval(function() {
              if(win.closed) {
                  clearInterval(timer);                  
                  enableParentWin();
              }
          }, 1000);
     }
     /*Function to enable parent window*/ 
     function enableParentWin() {
          window.document.getElementById('mainDiv').class="";
     }
     /*Function to enable parent window*/ 
     function disableParentWin() {
          window.document.getElementById('mainDiv').class="disableWin";
     }

</script>
</head>

<body>
<div id="mainDiv class="">
</div>
</body>    

'hg forget' is just shorthand for 'hg remove -Af'. From the 'hg remove' help:

...and -Af can be used to remove files from the next revision without deleting them from the working directory.

Bottom line: 'remove' deletes the file from your working copy on disk (unless you uses -Af) and 'forget' doesn't.

This will install jdk for you and check for the jarsigner inside it

sudo apt install -y default-jdk

to find jarsigner you can use whereis jarsigner

Just to add a little further documentation to this page - I have been struggling with this problem for a while.

As said above, the easiest way to get the URL is via window.location.href.

we can then extract parts of the URL through vanilla Javascript by using let urlElements = window.location.href.split('/')

We would then console.log(urlElements) to see the Array of elements produced by calling .split() on the URL.

Once you have found which index in the array you want to access, you can then assigned this to a variable

let urlElelement = (urlElements[0])

And now you can use the value of urlElement, which will be the specific part of your URL, wherever you want.

The answer was simply moving the PLSQL Developer folder from the "Program Files (x86) into the "Program Files" folder - weird!

I am using the following one: CSS Layout - 100 % height

Min-height

The #container element of this page has a min-height of 100%. That way, if the content requires more height than the viewport provides, the height of #content forces #container to become longer as well. Possible columns in #content can then be visualised with a background image on #container; divs are not table cells, and you don't need (or want) the physical elements to create such a visual effect. If you're not yet convinced; think wobbly lines and gradients instead of straight lines and simple color schemes.

Relative positioning

Because #container has a relative position, #footer will always remain at its bottom; since the min-height mentioned above does not prevent #container from scaling, this will work even if (or rather especially when) #content forces #container to become longer.

Padding-bottom

Since it is no longer in the normal flow, padding-bottom of #content now provides the space for the absolute #footer. This padding is included in the scrolled height by default, so that the footer will never overlap the above content.

Scale the text size a bit or resize your browser window to test this layout.

html,body {
    margin:0;
    padding:0;
    height:100%; /* needed for container min-height */
    background:gray;

    font-family:arial,sans-serif;
    font-size:small;
    color:#666;
}

h1 { 
    font:1.5em georgia,serif; 
    margin:0.5em 0;
}

h2 {
    font:1.25em georgia,serif; 
    margin:0 0 0.5em;
}
    h1, h2, a {
        color:orange;
    }

p { 
    line-height:1.5; 
    margin:0 0 1em;
}

div#container {
    position:relative; /* needed for footer positioning*/
    margin:0 auto; /* center, not in IE5 */
    width:750px;
    background:#f0f0f0;

    height:auto !important; /* real browsers */
    height:100%; /* IE6: treaded as min-height*/

    min-height:100%; /* real browsers */
}

div#header {
    padding:1em;
    background:#ddd url("../csslayout.gif") 98% 10px no-repeat;
    border-bottom:6px double gray;
}
    div#header p {
        font-style:italic;
        font-size:1.1em;
        margin:0;
    }

div#content {
    padding:1em 1em 5em; /* bottom padding for footer */
}
    div#content p {
        text-align:justify;
        padding:0 1em;
    }

div#footer {
    position:absolute;
    width:100%;
    bottom:0; /* stick to bottom */
    background:#ddd;
    border-top:6px double gray;
}
div#footer p {
    padding:1em;
    margin:0;
}

Works fine for me.

What does shapiro.test do?

shapiro.test tests the Null hypothesis that "the samples come from a Normal distribution" against the alternative hypothesis "the samples do not come from a Normal distribution".

How to perform shapiro.test in R?

The R help page for ?shapiro.test gives,

x - a numeric vector of data values. Missing values are allowed, 
    but the number of non-missing values must be between 3 and 5000.

That is, shapiro.test expects a numeric vector as input, that corresponds to the sample you would like to test and it is the only input required. Since you've a data.frame, you'll have to pass the desired column as input to the function as follows:

> shapiro.test(heisenberg$HWWIchg)
#   Shapiro-Wilk normality test

# data:  heisenberg$HWWIchg 
# W = 0.9001, p-value = 0.2528

Interpreting results from shapiro.test:

First, I strongly suggest you read this excellent answer from Ian Fellows on testing for normality.

As shown above, the shapiro.test tests the NULL hypothesis that the samples came from a Normal distribution. This means that if your p-value <= 0.05, then you would reject the NULL hypothesis that the samples came from a Normal distribution. As Ian Fellows nicely put it, you are testing against the assumption of Normality". In other words (correct me if I am wrong), it would be much better if one tests the NULL hypothesis that the samples do not come from a Normal distribution. Why? Because, rejecting a NULL hypothesis is not the same as accepting the alternative hypothesis.

In case of the null hypothesis of shapiro.test, a p-value <= 0.05 would reject the null hypothesis that the samples come from normal distribution. To put it loosely, there is a rare chance that the samples came from a normal distribution. The side-effect of this hypothesis testing is that this rare chance happens very rarely. To illustrate, take for example:

set.seed(450)
x <- runif(50, min=2, max=4)
shapiro.test(x)
#   Shapiro-Wilk normality test
# data:  runif(50, min = 2, max = 4) 
# W = 0.9601, p-value = 0.08995

So, this (particular) sample runif(50, min=2, max=4) comes from a normal distribution according to this test. What I am trying to say is that, there are many many cases under which the "extreme" requirements (p < 0.05) are not satisfied which leads to acceptance of "NULL hypothesis" most of the times, which might be misleading.

Another issue I'd like to quote here from @PaulHiemstra from under comments about the effects on large sample size:

An additional issue with the Shapiro-Wilk's test is that when you feed it more data, the chances of the null hypothesis being rejected becomes larger. So what happens is that for large amounts of data even very small deviations from normality can be detected, leading to rejection of the null hypothesis event though for practical purposes the data is more than normal enough.

Although he also points out that R's data size limit protects this a bit:

Luckily shapiro.test protects the user from the above described effect by limiting the data size to 5000.

If the NULL hypothesis were the opposite, meaning, the samples do not come from a normal distribution, and you get a p-value < 0.05, then you conclude that it is very rare that these samples do not come from a normal distribution (reject the NULL hypothesis). That loosely translates to: It is highly likely that the samples are normally distributed (although some statisticians may not like this way of interpreting). I believe this is what Ian Fellows also tried to explain in his post. Please correct me if I've gotten something wrong!

@PaulHiemstra also comments about practical situations (example regression) when one comes across this problem of testing for normality:

In practice, if an analysis assumes normality, e.g. lm, I would not do this Shapiro-Wilk's test, but do the analysis and look at diagnostic plots of the outcome of the analysis to judge whether any assumptions of the analysis where violated too much. For linear regression using lm this is done by looking at some of the diagnostic plots you get using plot(lm()). Statistics is not a series of steps that cough up a few numbers (hey p < 0.05!) but requires a lot of experience and skill in judging how to analysis your data correctly.

Here, I find the reply from Ian Fellows to Ben Bolker's comment under the same question already linked above equally (if not more) informative:

For linear regression,

1. Don't worry much about normality. The CLT takes over quickly and if you have all but the smallest sample sizes and an even remotely reasonable looking histogram you are fine.

2. Worry about unequal variances (heteroskedasticity). I worry about this to the point of (almost) using HCCM tests by default. A scale location plot will give some idea of whether this is broken, but not always. Also, there is no a priori reason to assume equal variances in most cases.

3. Outliers. A cooks distance of > 1 is reasonable cause for concern.

Those are my thoughts (FWIW).

Hope this clears things up a bit.

Additionally since $this:: has not been discussed yet.

For informational purposes only, as of PHP 5.3 when dealing with instantiated objects to get the current scope value, as opposed to using static::, one can alternatively use $this:: like so.

http://ideone.com/7etRHy

class Foo
{
    const NAME = 'Foo';

    //Always Foo::NAME (Foo) due to self
    protected static $staticName = self::NAME;

    public function __construct()
    {
        echo $this::NAME;
    }

    public function getStaticName()
    {
       echo $this::$staticName;
    }
}

class Bar extends Foo
{
    const NAME = 'FooBar';

    /**
     * override getStaticName to output Bar::NAME
     */
    public function getStaticName()
    {
        $this::$staticName = $this::NAME;
        parent::getStaticName();
    }
}

$foo = new Foo; //outputs Foo
$bar = new Bar; //outputs FooBar
$foo->getStaticName(); //outputs Foo
$bar->getStaticName(); //outputs FooBar
$foo->getStaticName(); //outputs FooBar

Using the code above is not common or recommended practice, but is simply to illustrate its usage, and is to act as more of a "Did you know?" in reference to the original poster's question.

It also represents the usage of $object::CONSTANT for example echo $foo::NAME; as opposed to $this::NAME;

For the mocks initialization, using the runner or the MockitoAnnotations.initMocks are strictly equivalent solutions. From the javadoc of the MockitoJUnitRunner :

JUnit 4.5 runner initializes mocks annotated with Mock, so that explicit usage of MockitoAnnotations.initMocks(Object) is not necessary. Mocks are initialized before each test method.

The first solution (with the MockitoAnnotations.initMocks) could be used when you have already configured a specific runner (SpringJUnit4ClassRunner for example) on your test case.

The second solution (with the MockitoJUnitRunner) is the more classic and my favorite. The code is simpler. Using a runner provides the great advantage of automatic validation of framework usage (described by @David Wallace in this answer).

Both solutions allows to share the mocks (and spies) between the test methods. Coupled with the @InjectMocks, they allow to write unit tests very quickly. The boilerplate mocking code is reduced, the tests are easier to read. For example:

@RunWith(MockitoJUnitRunner.class)
public class ArticleManagerTest {

    @Mock private ArticleCalculator calculator;
    @Mock(name = "database") private ArticleDatabase dbMock;
    @Spy private UserProvider userProvider = new ConsumerUserProvider();

    @InjectMocks private ArticleManager manager;

    @Test public void shouldDoSomething() {
        manager.initiateArticle();
        verify(database).addListener(any(ArticleListener.class));
    }

    @Test public void shouldDoSomethingElse() {
        manager.finishArticle();
        verify(database).removeListener(any(ArticleListener.class));
    }
}

Pros: The code is minimal

Cons: Black magic. IMO it is mainly due to the @InjectMocks annotation. With this annotation "you loose the pain of code" (see the great comments of @Brice)

The third solution is to create your mock on each test method. It allow as explained by @mlk in its answer to have "self contained test".

public class ArticleManagerTest {

    @Test public void shouldDoSomething() {
        // given
        ArticleCalculator calculator = mock(ArticleCalculator.class);
        ArticleDatabase database = mock(ArticleDatabase.class);
        UserProvider userProvider = spy(new ConsumerUserProvider());
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.initiateArticle();

        // then 
        verify(database).addListener(any(ArticleListener.class));
    }

    @Test public void shouldDoSomethingElse() {
        // given
        ArticleCalculator calculator = mock(ArticleCalculator.class);
        ArticleDatabase database = mock(ArticleDatabase.class);
        UserProvider userProvider = spy(new ConsumerUserProvider());
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.finishArticle();

        // then
        verify(database).removeListener(any(ArticleListener.class));
    }
}

Pros: You clearly demonstrate how your api works (BDD...)

Cons: there is more boilerplate code. (The mocks creation)

My recommandation is a compromise. Use the @Mock annotation with the @RunWith(MockitoJUnitRunner.class), but do not use the @InjectMocks :

@RunWith(MockitoJUnitRunner.class)
public class ArticleManagerTest {

    @Mock private ArticleCalculator calculator;
    @Mock private ArticleDatabase database;
    @Spy private UserProvider userProvider = new ConsumerUserProvider();

    @Test public void shouldDoSomething() {
        // given
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.initiateArticle();

        // then 
        verify(database).addListener(any(ArticleListener.class));
    }

    @Test public void shouldDoSomethingElse() {
        // given
        ArticleManager manager = new ArticleManager(calculator, 
                                                    userProvider, 
                                                    database);

        // when 
        manager.finishArticle();

        // then 
        verify(database).removeListener(any(ArticleListener.class));
    }
}

Pros: You clearly demonstrate how your api works (How my ArticleManager is instantiated). No boilerplate code.

Cons: The test is not self contained, less pain of code

another solution:
add src/myproject to $GOPATH.

Then import "mylib" will compile.

You can use pydash:

import pydash as _

_.get(example_dict, 'key1.key2', default='Default')

https://pydash.readthedocs.io/en/latest/api.html

you can configure IIS in IIS Mgr to use EVERY port between 1 and 65535 as long it is not used by any other application

open dconf Editor and go to org > gnome > desktop > application > terminal and change gnome-terminal to terminator

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

var resizeTimer;
$( window ).resize(function() {
    if(resizeTimer){
        clearTimeout(resizeTimer);
    }
    resizeTimer = setTimeout(function() {
        //your code here
        resizeTimer = null;
        }, 200);
    });

This worked for what I was trying to do in chrome. This won't fire the callback until 200ms after last resize event.

Where possible, I prefer to call the function rather than dispatch an event. This works well if you have control over the code you want to run, but see below for cases where you don't own the code.

window.onresize = doALoadOfStuff;

function doALoadOfStuff() {
    //do a load of stuff
}

In this example, you can call the doALoadOfStuff function without dispatching an event.

In your modern browsers, you can trigger the event using:

window.dispatchEvent(new Event('resize'));

This doesn't work in Internet Explorer, where you'll have to do the longhand:

var resizeEvent = window.document.createEvent('UIEvents'); 
resizeEvent.initUIEvent('resize', true, false, window, 0); 
window.dispatchEvent(resizeEvent);

jQuery has the trigger method, which works like this:

$(window).trigger('resize');

And has the caveat:

Although .trigger() simulates an event activation, complete with a synthesized event object, it does not perfectly replicate a naturally-occurring event.

You can also simulate events on a specific element...

function simulateClick(id) {
  var event = new MouseEvent('click', {
    'view': window,
    'bubbles': true,
    'cancelable': true
  });

  var elem = document.getElementById(id); 

  return elem.dispatchEvent(event);
}

To get the filter method from user1106925 working in <=IE11 if needed

You can replace the spread operator with:

[].slice.call(document.querySelectorAll("a"))

and the includes call with a.textContent.match("your search term")

which works pretty neatly:

[].slice.call(document.querySelectorAll("a"))
   .filter(a => a.textContent.match("your search term"))
   .forEach(a => console.log(a.textContent))

There are several options:

ps -fp <pid>
cat /proc/<pid>/cmdline | sed -e "s/\x00/ /g"; echo

There is more info in /proc/<pid> on Linux, just have a look.

On other Unixes things might be different. The ps command will work everywhere, the /proc stuff is OS specific. For example on AIX there is no cmdline in /proc.

This elegant solution works for number of submit buttons:

@Html.Begin()
{
  // Html code here
  <input type="submit" name="command" value="submit1" />
  <input type="submit" name="command" value="submit2" />

}

And in your controllers' action method accept it as a parameter.

public ActionResult Create(Employee model, string command)
{
    if(command.Equals("submit1"))
    {
      // Call action here...
    }
    else
    {
      // Call another action here...
    }
}

That's the compiler that comes with Apple's XCode tools package. They've hacked on it a little, but basically it's just g++.

You can download XCode for free (well, mostly, you do have to sign up to become an ADC member, but that's free too) here: http://developer.apple.com/technology/xcode.html

Edit 2013-01-25: This answer was correct in 2010. It needs an update.

While XCode tools still has a command-line C++ compiler, In recent versions of OS X (I think 10.7 and later) have switched to clang/llvm (mostly because Apple wants all the benefits of Open Source without having to contribute back and clang is BSD licensed). Secondly, I think all you have to do to install XCode is to download it from the App store. I'm pretty sure it's free there.

So, in order to get g++ you'll have to use something like homebrew (seemingly the current way to install Open Source software on the Mac (though homebrew has a lot of caveats surrounding installing gcc using it)), fink (basically Debian's apt system for OS X/Darwin), or MacPorts (Basically, OpenBSDs ports system for OS X/Darwin) to get it.

Fink definitely has the right packages. On 2016-12-26, it had gcc 5 and gcc 6 packages.

I'm less familiar with how MacPorts works, though some initial cursory investigation indicates they have the relevant packages as well.

If you're using Laravel 5, the command would be;

php artisan make:migration add_paid_to_users

All of the commands for making things (controllers, models, migrations etc) have been moved under the make: command.

php artisan migrate is still the same though.

There is a simple way of doing it. This may not be the expert answer and it may not work for everyone but it did for me.

Uncheck all primary and unique check boxes, jut create a plain simple table.

When phpmyadmin (or other) shows you the table structure, make the column primary by the given button.

Then click on change and edit the settings of that or other colums like 'unique' etc.

Creating a new base collection for each eloquent collection the merge works for me.

$foo = collect(Foo::all());
$bar = collect(Bar::all());
$merged = $foo->merge($bar);

In this case don't have conflits by its primary keys.

Add toString() method to your address class then do

System.out.println(Arrays.toString(houseAddress));

Of course if you're lazy like me, you could just do this:

Declare @Ids varchar(50) Set @Ids = ',1,2,3,5,4,6,7,98,234,'

Select * from sometable
 where Charindex(','+cast(tableid as varchar(8000))+',', @Ids) > 0

If your VARCHAR column contains empty strings (which are not the same as NULL for PostgreSQL as you might recall) you will have to use something in the line of the following to set a default:

ALTER TABLE presales ALTER COLUMN code TYPE NUMERIC(10,0)
            USING COALESCE(NULLIF(code, '')::NUMERIC, 0);

(found with the help of this answer)

Unfortunately that approach is not portable C++ (so far).

All standard names are in namespace std and moreover you cannot know which names are NOT defined by including and header (in other words it's perfectly legal for an implementation to declare the name std::string directly or indirectly when using #include <vector>).

Despite this however you are required by the language to know and tell the compiler which standard header includes which part of the standard library. This is a source of portability bugs because if you forget for example #include <map> but use std::map it's possible that the program compiles anyway silently and without warnings on a specific version of a specific compiler, and you may get errors only later when porting to another compiler or version.

In my opinion there are no valid technical excuses because this is necessary for the general user: the compiler binary could have all standard namespace built in and this could actually increase the performance even more than precompiled headers (e.g. using perfect hashing for lookups, removing standard headers parsing or loading/demarshalling and so on).

The use of standard headers simplifies the life of who builds compilers or standard libraries and that's all. It's not something to help users.

However this is the way the language is defined and you need to know which header defines which names so plan for some extra neurons to be burnt in pointless configurations to remember that (or try to find and IDE that automatically adds the standard headers you use and removes the ones you don't... a reasonable alternative).

I had the same problem on Mac 10.7.5 with git version 1.7.12.4

When I ran gitk I got an error:

"Error in startup script: expected version number but got "Git-37)"
    while executing
"package vcompare $git_version "1.6.6.2""
    invoked from within
"if {[package vcompare $git_version "1.6.6.2"] >= 0} {
    set show_notes "--show-notes"
}"
    (file "/usr/bin/gitk" line 11587)

When I looked at the code in gitk I saw the line that sets the version.

set git_version [join [lrange [split [lindex [exec git version] end] .] 0 2] .]

This somehow parsed the git version results to Git-37 instead of 1.7.12.4

I just replaced the git_version line with:

set git_version "1.7.12.4"

If you get your dates from a database and do a for loop for each row and append it to a string to use in javascript to automagically populate datatables, it will need to look like this. Note that when using the hidden span trick, you need to account for the single digit numbers of the date like if its the 6th hour, you need to add a zero before it otherwise the span trick doesn't work in the sorting.. Example of code:

 DateTime getDate2 = Convert.ToDateTime(row["date"]);
 var hour = getDate2.Hour.ToString();
 if (hour.Length == 1)
 {
 hour = "0" + hour;
 }
 var minutes = getDate2.Minute.ToString();
 if (minutes.Length == 1)
 {
 minutes = "0" + minutes;
 }
 var year = getDate2.Year.ToString();
 var month = getDate2.Month.ToString();
 if (month.Length == 1)
 {
 month = "0" + month;
 }
 var day = getDate2.Day.ToString();
 if (day.Length == 1)
 {
 day = "0" + day;
 }
 var dateForSorting = year + month + day + hour + minutes; 
 dataFromDatabase.Append("<span style=\u0022display:none;\u0022>" + dateForSorting +
 </span>");

Assuming you want to add this path for all users on the system, add the following line to your /etc/profile.d/play.sh (and possibly play.csh, etc):

PATH=$PATH:/home/me/play
export PATH

Are you concerned about the profile picture size? at the time of implementing login with Facebook using PHP. We’ll show you the simple way to get large size profile picture in Facebook PHP SDK. Also, you can get the custom size image of Facebook profile.

Set the profile picture dimension by using the following line of code.

$userProfile = $facebook->api('/me?fields=picture.width(400).height(400)');

check this post:http://www.codexworld.com/how-to-guides/get-large-size-profile-picture-in-facebook-php-sdk/

All answers here are still using the FormData API. It is like a "multipart/form-data" upload without a form. You can also upload the file directly as content inside the body of the POST request using xmlHttpRequest like this:

var xmlHttpRequest = new XMLHttpRequest();

var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...

xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);

Content-Type and Content-Disposition headers are used for explaining what we are sending (mime-type and file name).

I posted similar answer also here.

>>> li = ['aaa', 'bbb']
>>> li.insert(0, 'wow!')
>>> li
['wow!', 'aaa', 'bbb']

You can use the StringUtils class in Apache Commons:

StringUtils.substringAfterLast(one, "-");

Using JQuery you can do the following:

// for the element which uses ID
$("#id").trigger("change");

// for the element which uses class name
$(".class_name").trigger("change");

Atomic

• is the default behavior
• will ensure the present process is completed by the CPU, before another process accesses the variable
• is not fast, as it ensures the process is completed entirely

Non-Atomic

• is NOT the default behavior
• faster (for synthesized code, that is, for variables created using @property and @synthesize)
• not thread-safe
• may result in unexpected behavior, when two different process access the same variable at the same time

Simple 3-Step Solution

Abstract: You need to set the owner of the directory to the user that PHP uses (web server user).

Step 1: Determine PHP User

Create a PHP file containing the following:

<?php echo `whoami`; ?>

Upload it to your web server. The output should be similar to the following:

www-data

Therefore, the PHP user is www-data.

Step 2: Determine Owner of Directory

Next, check the details of the web directory via the command line:

ls -dl /var/www/example.com/public_html/example-folder

The result should be similar to the following:

drwxrwxr-x 2 exampleuser1 exampleuser2 4096 Mar 29 16:34 example-folder

Therefore, the owner of the directory is exampleuser1.

Step 3: Change Directory Owner to PHP User

Afterwards, change the owner of the web directory to the PHP user:

sudo chown -R www-data /var/www/example.com/public_html/example-folder

Verify that the owner of the web directory has been changed:

ls -dl /var/www/example.com/public_html/example-folder

The result should be similar to the following:

drwxrwxr-x 2 www-data exampleuser2 4096 Mar 29 16:34 example-folder

Therefore, the owner of example-folder has successfully been changed to the PHP user: www-data.

Done! PHP should now be able to write to the directory.

I was also having this issue of "You have mail" coming up every time I started Terminal.

What I discovered is this.

Something I'd installed (not entirely sure what, but possibly a script or something associated with an Alfred Workflow [at a guess]) made a change to the OS X system to start presenting Terminal bash notifications. Prior to that, it appears Wordpress had attempted to use the Local Mail system to send a message. The message bounced, due to it having an invalid Recipient address. The bounced message then ended up in the local system mail inbox. So Terminal (bash) was then notifying me that "You have mail".

You can access the mail by simply using the command

mail

This launches you into Mail, and it will right away show you a list of messages that are stored there. If you want to see the content of the first message, use

t

This will show you the content of the first message, in full. You'll need to scroll down through the message to view it all, by hitting the down-arrow key.

If you want to jump to the end of the message, use the

spacebar

If you want to abort viewing the message, use

q 

To view the next message in the queue use

n

... assuming there's more than one message.

NOTE: You need to use these commands at the mail ? command prompt. They won't work whilst you are in the process of viewing a message. Hitting n whilst viewing a message will just cause an error message related to regular expressions. So, if in the midst of viewing a message, hit q to quit from that, or hit spacebar to jump to the end of the message, and then at the ? prompt, hit n.

Viewing the content of the messages in this way may help you identify what attempted to send the message(s).

You can also view a specific message by just inputting its number at the ? prompt. 3, for instance, will show you the content of the third message (if there are that many in there).

Use the d command (at the ? command prompt )

d [message number]

To delete each message when you are done looking at them. For example, d 2 will delete message number 2. Or you can delete a list of messages, such as d 1 2 5 7. Or you can delete a range of messages with (for example), d 3-10. You can find the message numbers in the list of messages mail shows you.

To delete all the messages, from the mail prompt (?) use the command d *.

As per a comment on this post, you will need to use q to quit mail, which also saves any changes.

If you'd like to see the mail all in one output, use this command at the bash prompt (i.e. not from within mail, but from your regular command prompt):

cat /var/mail/<username>

And, if you wish to delete the emails all in one hit, use this command

sudo rm /var/mail/<username>

In my particular case, there were a number of messages. It looks like the one was a returned message that bounced. It was sent by a local Wordpress installation. It was a notification for when user "Admin" (me) changed its password. Two additional messages where there. Both seemed to be to the same incident.

What I don't know, and can't answer for you either, is WHY I only recently started seeing this mail notification each time I open Terminal. The mails were generated a couple of months ago, and yet I only noticed this "you have mail" appearing in the last few weeks. I suspect it's the result of something a workflow I installed in Alfred, and that workflow using Terminal bash to provide notifications... or something along those lines.

Simply deleting the messages

If you have no interest in determining the source of the messages, and just wish to get rid of them, it may be easier to do so without using the mail command (which can be somewhat fiddly). As pointed out by a few other people, you can use this command instead:

sudo rm /var/mail/YOURUSERNAME

Since you've already received help on the query, I'll take a poke at your syntax question:

The first query employs some lesser-known ANSI SQL syntax which allows you to nest joins between the join and on clauses. This allows you to scope/tier your joins and probably opens up a host of other evil, arcane things.

Now, while a nested join cannot refer any higher in the join hierarchy than its immediate parent, joins above it or outside of its branch can refer to it... which is precisely what this ugly little guy is doing:

select
 count(*)
from Table1 as t1
join Table2 as t2
    join Table3 as t3
    on t2.Key = t3.Key                   -- join #1
    and t2.Key2 = t3.Key2 
on t1.DifferentKey = t3.DifferentKey     -- join #2  

This looks a little confusing because join #2 is joining t1 to t2 without specifically referencing t2... however, it references t2 indirectly via t3 -as t3 is joined to t2 in join #1. While that may work, you may find the following a bit more (visually) linear and appealing:

select
 count(*)
from Table1 as t1
    join Table3 as t3
        join Table2 as t2
        on t2.Key = t3.Key                   -- join #1
        and t2.Key2 = t3.Key2   
    on t1.DifferentKey = t3.DifferentKey     -- join #2

Personally, I've found that nesting in this fashion keeps my statements tidy by outlining each tier of the relationship hierarchy. As a side note, you don't need to specify inner. join is implicitly inner unless explicitly marked otherwise.

(d means decimal, b means binary)

1. 12.25d is your float.
2. You write 12d in binary and remove it from your float. Only the remainder (.25d) will be left.
3. You write the dot.
4. While the remainder (0.25d) is not zero (and/or you want more digits), multiply it with 2 (-> 0.50d), remove and write the digit left of the dot (0), and continue with the new remainder (.50d).

You would need to decompile the apk as Davis suggested, can use tools such as apkTool , then if you need to change the source code you would need other tools to do that.

You would then need to put the apk back together and sign it, if you don't have the original key used to sign the apk this means the new apk will have a different signature.

If the developer employed any obfuscation or other techniques to protect the app then it gets more complicated.

In short its a pretty complex and technical procedure, so if the developer is really just out of reach, its better to wait until he is in reach. And ask for the source code next time.

You could also put your JSON content in a file and pass it to curl using the --upload-file option via standard input, like this:

 echo 'my.awesome.json.function({"do" : "whatever"})' | curl -X POST "http://url" -T -

In some cases, i.e. when (if) you're just using float to have elements flow on the same "line", you might use

display: inline-block;

instead of

float: left;

Otherwise, using a clear element at the end works, even if it may go against the grain to need an element to do what should be CSS work.

For me it depends on the component. If you know what you need it to be populated with then you should try to specify exclusively, or multiple types using:

PropTypes.oneOfType 

If you want to refer to a React component then you will be looking for

PropTypes.element

Although,

PropTypes.node

describes anything that can be rendered - strings, numbers, elements or an array of these things. If this suits you then this is the way.

With very generic components, who can have many types of children, you can also use the below - though bare in mind that eslint and ts may not be happy with this lack of specificity:

PropTypes.any

I would recommend everyone look into CSS grids. It has been supported by most browsers now since about 2017. Here is a link to some documentation: https://css-tricks.com/snippets/css/complete-guide-grid/ . It is so much easier to keep your page elements where you want them, especially when it comes to responsiveness. It took me all of 20 minutes to learn how to do it, and I'm a newbie!

<div class="grid-div">
    <p class="hello">Hello</p>
    <p class="world">World</p>
</div>


//begin css//

.grid-div {
    display: grid;
    grid-template-columns: 50% 50%;
    grid-template-rows: 50% 50%;
}

.hello {
    grid-column-start: 2;
    grid-row-start: 2;
}

.world {
    grid-column-start: 1;
    grid-row-start: 2;
}

This code will split the page into 4 equal quadrants, placing the "Hello" in the bottom right, and the "World" in the bottom left without having to change their positioning or playing with margins.

This can be extrapolated into very complex grid layouts with overlapping, infinite grids of all sizes, and even grids nested inside grids, without losing control of your elements every time something changes (MS Word I'm looking at you).

Hope this helps whoever still needs it!

Anti-aliasing cannot be turned on or off, and is controlled by the browser.

Can I turn off antialiasing on an HTML <canvas> element?

If you want to run a task that's associated with a host, but on different host, you should try delegate_to.

In your case, you should delegate to your localhost (ansible master) and calling ansible-playbook command

1. You need to open the project file of your program and it should appear on Management panel.

2. Right click on the project file, then select add file. You should add the 3 source code (secrypt.h, secrypt.cpp, and the trial.cpp)

3. Compile and enjoy. Hope, I could help you.

If you want to check your URL. I suppose you are using Chrome. You can go to chrome console and URL will be displayed under "XHR finished loading:"

Might not be so related to the issue above. However if you are looking for a way to serialize Java object as string, this could come in hand

            objectOutputStream.flush();
            return new String(base64.encode(arrayOutputStream.toByteArray()));
        }
    }

    public static Object deserializeObjectFromString(String objectString) throws IOException, ClassNotFoundException {
        try (
                ByteArrayInputStream arrayInputStream = new ByteArrayInputStream(base64.decode(objectString));
                GZIPInputStream gzipInputStream = new GZIPInputStream(arrayInputStream);
                ObjectInputStream objectInputStream = new ObjectInputStream(gzipInputStream)) {
            return objectInputStream.readObject();
        }
    }
}

I have created an action in the Accounts controller that calls a function to create the roles and assign the Admin role to the default user. (You should probably remove the default user in production):

    private async Task CreateRolesandUsers()
    {  
        bool x = await _roleManager.RoleExistsAsync("Admin");
        if (!x)
        {
            // first we create Admin rool    
            var role = new IdentityRole();
            role.Name = "Admin";
            await _roleManager.CreateAsync(role);

            //Here we create a Admin super user who will maintain the website                   

            var user = new ApplicationUser();
            user.UserName = "default";
            user.Email = "[email protected]";

            string userPWD = "somepassword";

            IdentityResult chkUser = await _userManager.CreateAsync(user, userPWD);

            //Add default User to Role Admin    
            if (chkUser.Succeeded)
            {
                var result1 = await _userManager.AddToRoleAsync(user, "Admin");
            }
        }

        // creating Creating Manager role     
        x = await _roleManager.RoleExistsAsync("Manager");
        if (!x)
        {
            var role = new IdentityRole();
            role.Name = "Manager";
            await _roleManager.CreateAsync(role);
        }

        // creating Creating Employee role     
        x = await _roleManager.RoleExistsAsync("Employee");
        if (!x)
        {
            var role = new IdentityRole();
            role.Name = "Employee";
            await _roleManager.CreateAsync(role);
        }
  }

After you could create a controller to manage roles for the users.

Option 1

Use the fact that a data.frame is a list of columns, then use do.call to recreate a data.frame.

do.call(data.frame,lapply(DT, function(x) replace(x, is.infinite(x),NA)))

Option 2 -- data.table

You could use data.table and set. This avoids some internal copying.

DT <- data.table(dat)
invisible(lapply(names(DT),function(.name) set(DT, which(is.infinite(DT[[.name]])), j = .name,value =NA)))

Or using column numbers (possibly faster if there are a lot of columns):

for (j in 1:ncol(DT)) set(DT, which(is.infinite(DT[[j]])), j, NA)

Timings

# some `big(ish)` data
dat <- data.frame(a = rep(c(1,Inf), 1e6), b = rep(c(Inf,2), 1e6), 
                  c = rep(c('a','b'),1e6),d = rep(c(1,Inf), 1e6),  
                  e = rep(c(Inf,2), 1e6))
# create data.table
library(data.table)
DT <- data.table(dat)

# replace (@mnel)
system.time(na_dat <- do.call(data.frame,lapply(dat, function(x) replace(x, is.infinite(x),NA))))
## user  system elapsed 
#  0.52    0.01    0.53 

# is.na (@dwin)
system.time(is.na(dat) <- sapply(dat, is.infinite))
# user  system elapsed 
# 32.96    0.07   33.12 

# modified is.na
system.time(is.na(dat) <- do.call(cbind,lapply(dat, is.infinite)))
#  user  system elapsed 
# 1.22    0.38    1.60 


# data.table (@mnel)
system.time(invisible(lapply(names(DT),function(.name) set(DT, which(is.infinite(DT[[.name]])), j = .name,value =NA))))
# user  system elapsed 
# 0.29    0.02    0.31 

data.table is the quickest. Using sapply slows things down noticeably.

Make sure your project is 32 bit.

I had this problem, as soon as I ticked "Prefer 32 bit and rebuilt" all the Office Interop assemblies where available in Reference->Assemblies->Search "Office".

You can use method clearly.

This worked for me

Deactivate AdBlock.

Go to inspect -> settings gear -> Uncheck 'enable javascript source maps' and 'enable css source map'.

Refresh.

You can use this code snippet ...

<html>
  <body>
     <form>
          <input type="radio" name="color" value="black" required />
          <input type="radio" name="color" value="white" />
          <input type="submit" value="Submit" />
    </form>
  </body>
</html>

Specify "required" keyword in one of the select statements. If you want to change the default way of its appearance. You can follow these steps. This is just for extra info if you have any intention to modify the default behavior.

Add the following into you .css file.

/* style all elements with a required attribute */
:required {
  background: red;
}

For more information you can refer following URL.

https://css-tricks.com/almanac/selectors/r/required/

Like many others, I would suggest implementing a to_dict() function rather than (or in addition to) allowing casting to a dictionary. I think it makes it more obvious that the class supports that kind of functionality. You could easily implement such a method like this:

def to_dict(self):
    class_vars = vars(MyClass)  # get any "default" attrs defined at the class level
    inst_vars = vars(self)  # get any attrs defined on the instance (self)
    all_vars = dict(class_vars)
    all_vars.update(inst_vars)
    # filter out private attributes
    public_vars = {k: v for k, v in all_vars.items() if not k.startswith('_')}
    return public_vars

I know it isn't C but asm:

var1 dw 0f0f0
clc
     push ax
     push cx
     mov cx 16
loop1:
     shl var1
     shr ax
loop loop1
     pop ax
     pop cx

This works with the carry bit, so you may save flags too

This will print the data in columns and comes to new line once last column is reached.

ResultSetMetaData resultSetMetaData = res.getMetaData();
int columnCount = resultSetMetaData.getColumnCount();
for(int i =1; i<=columnCount; i++){
                if(!(i==columnCount)){

                    System.out.print(res.getString(i)+"\t");
                }
                else{
                    System.out.println(res.getString(i));
                }

            }

You can make <button> tag to do action like this:

<a href="http://www.google.com/">
   <button>Visit Google</button>
</a>

or:

<a href="http://www.google.com/">
   <input type="button" value="Visit Google" />
</a>

It's simple and no javascript required!

NOTE:

This approach is not valid from HTML structure. But, it works on many modern browser. See following reference :

• For <button>; and
• For <input type="button />

What you really want may simply be an enumeration

If you're looking for something that behaves like an enumeration (because I see you are defining an object and attaching a sequential ID 0, 1, 2 and contains a name field that you don't want to misspell (e.g. name vs naaame), you're better off defining an enumeration because the sequential ID is taken care of automatically, and provides type verification for you out of the box.

enum TestStatus {
    Available,     // 0
    Ready,         // 1
    Started,       // 2
}

class Test {
    status: TestStatus
}

var test = new Test();
test.status = TestStatus.Available; // type and spelling is checked for you,
                                    // and the sequence ID is automatic

The values above will be automatically mapped, e.g. "0" for "Available", and you can access them using TestStatus.Available. And Typescript will enforce the type when you pass those around.

If you insist on defining a new type as an array of your custom type

You wanted an array of objects, (not exactly an object with keys "0", "1" and "2"), so let's define the type of the object, first, then a type of a containing array.

class TestStatus {
    id: number
    name: string

    constructor(id, name){
        this.id = id;
        this.name = name;
    }
}

type Statuses = Array<TestStatus>;

var statuses: Statuses = [
    new TestStatus(0, "Available"),
    new TestStatus(1, "Ready"),
    new TestStatus(2, "Started")
]

You don't need ANY of these other fancy answers. Below is a simplistic example that doesn't have all the Margin, Height, Width properties set in the XAML, but should be enough to show how to get this done at a basic level.

XAML
Build a Window page like you would normally and add your fields to it, say a Label and TextBox control inside a StackPanel:

<StackPanel Orientation="Horizontal">
    <Label Name="lblUser" Content="User Name:" />
    <TextBox Name="txtUser" />
</StackPanel>

Then create a standard Button for Submission ("OK" or "Submit") and a "Cancel" button if you like:

<StackPanel Orientation="Horizontal">
    <Button Name="btnSubmit" Click="btnSubmit_Click" Content="Submit" />
    <Button Name="btnCancel" Click="btnCancel_Click" Content="Cancel" />
</StackPanel>

Code-Behind
You'll add the Click event handler functions in the code-behind, but when you go there, first, declare a public variable where you will store your textbox value:

public static string strUserName = String.Empty;

Then, for the event handler functions (right-click the Click function on the button XAML, select "Go To Definition", it will create it for you), you need a check to see if your box is empty. You store it in your variable if it is not, and close your window:

private void btnSubmit_Click(object sender, RoutedEventArgs e)
{        
    if (!String.IsNullOrEmpty(txtUser.Text))
    {
        strUserName = txtUser.Text;
        this.Close();
    }
    else
        MessageBox.Show("Must provide a user name in the textbox.");
}

Calling It From Another Page
You're thinking, if I close my window with that this.Close() up there, my value is gone, right? NO!! I found this out from another site: http://www.dreamincode.net/forums/topic/359208-wpf-how-to-make-simple-popup-window-for-input/

They had a similar example to this (I cleaned it up a bit) of how to open your Window from another and retrieve the values:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void btnOpenPopup_Click(object sender, RoutedEventArgs e)
    {
        MyPopupWindow popup = new MyPopupWindow();  // this is the class of your other page

        //ShowDialog means you can't focus the parent window, only the popup
        popup.ShowDialog(); //execution will block here in this method until the popup closes

        string result = popup.strUserName;
        UserNameTextBlock.Text = result;  // should show what was input on the other page
    }
}

Cancel Button
You're thinking, well what about that Cancel button, though? So we just add another public variable back in our pop-up window code-behind:

public static bool cancelled = false;

And let's include our btnCancel_Click event handler, and make one change to btnSubmit_Click:

private void btnCancel_Click(object sender, RoutedEventArgs e)
{        
    cancelled = true;
    strUserName = String.Empty;
    this.Close();
}

private void btnSubmit_Click(object sender, RoutedEventArgs e)
{        
    if (!String.IsNullOrEmpty(txtUser.Text))
    {
        strUserName = txtUser.Text;
        cancelled = false;  // <-- I add this in here, just in case
        this.Close();
    }
    else
        MessageBox.Show("Must provide a user name in the textbox.");
}

And then we just read that variable in our MainWindow btnOpenPopup_Click event:

private void btnOpenPopup_Click(object sender, RoutedEventArgs e)
{
    MyPopupWindow popup = new MyPopupWindow();  // this is the class of your other page
    //ShowDialog means you can't focus the parent window, only the popup
    popup.ShowDialog(); //execution will block here in this method until the popup closes

    // **Here we find out if we cancelled or not**
    if (popup.cancelled == true)
        return;
    else
    {
        string result = popup.strUserName;
        UserNameTextBlock.Text = result;  // should show what was input on the other page
    }
}

Long response, but I wanted to show how easy this is using public static variables. No DialogResult, no returning values, nothing. Just open the window, store your values with the button events in the pop-up window, then retrieve them afterwards in the main window function.

Plain vanilla JDBC does not support named parameters.

If you are using DB2 then using DB2 classes directly:

1. Using named parameter markers with PreparedStatement objects
2. Using named parameter markers with CallableStatement objects

You could also try to import it with the "InjectionToken". As described here: Use jQuery in Angular/Typescript without a type definition

You can simply inject the jQuery global instance and use it. For this you won't be needing any type definitions or typings.

import { InjectionToken } from '@angular/core';

export const JQ_TOKEN = new InjectionToken('jQuery');

export function jQueryFactory() {
    return window['jQuery'];
}

export const JQUERY_PROVIDER = [
    { provide: JQ_TOKEN, useFactory: jQueryFactory },
];

When set correctly in your app.module.ts:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppComponent } from './app.component';

import { JQ_TOKEN } from './jQuery.service';

declare let jQuery: Object;

@NgModule({
    imports: [
        BrowserModule
    ],
    declarations: [
        AppComponent
    ],
    providers: [
        { provide: JQ_TOKEN, useValue: jQuery }
    ],
    bootstrap: [AppComponent]
})
export class AppModule { }

You can start using it in your components:

import { Component, Inject } from '@angular/core';
import { JQ_TOKEN } from './jQuery.service';

@Component({
    selector: "selector",
    templateUrl: 'somefile.html'
})
export class SomeComponent {
    constructor( @Inject(JQ_TOKEN) private $: any) { }

    somefunction() {
        this.$('...').doSomething();
    }
}

I've always had a habit of just using std::endl because it is easy for me to see.

if you want to use only arraylist then I am worried there is no better way which will create a huge performance benefit. But by only using arraylist i would check before adding into the list like following

void addToList(String s){
  if(!yourList.contains(s))
       yourList.add(s);
}

In this cases using a Set is suitable.

If you are using Clojure, you have another option:

(defn map-entry
  [k v]
  (clojure.lang.MapEntry/create k v))

Javascript:

document.getElementById("ID").style.background = "colorName"; //JS ID

document.getElementsByClassName("ClassName")[0].style.background = "colorName"; //JS Class

Jquery:

$('#ID/.className').css("background","colorName") // One style

$('#ID/.className').css({"background":"colorName","color":"colorname"}); //Multiple style

Add the image to Your project by clicking File -> "Add Files to ...".

Then choose the image in ImageView properties (Utilities -> Attributes Inspector).

No.

localStorage is accessible by any webpage, and if you have the key, you can change whatever data you want.

That being said, if you can devise a way to safely encrypt the keys, it doesn't matter how you transfer the data, if you can contain the data within a closure, then the data is (somewhat) safe.

For those who struggle at capturing Enter key on TextBox or other input control, if your Form has AcceptButton defined, you will not be able to use KeyDown event to capture Enter.

What you should do is to catch the Enter key at form level. Add this code to the form:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    if ((this.ActiveControl == myTextBox) && (keyData == Keys.Return))
    {
        //do something
        return true;
    }
    else
    {
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

@ClassRule
public static TestRule watchman = new TestWatcher() {
    @Override
    protected void starting( final Description description ) {
        String mN = description.getMethodName();
        if ( mN == null ) {
            mN = "setUpBeforeClass..";
        }

        final String s = StringTools.toString( "starting..JUnit-Test: %s.%s", description.getClassName(), mN );
        System.err.println( s );
    }
};

According to Microsoft's archived Internet Explorer Dev Center, document.all is deprecated in IE 11 and Edge!

a much more practical way for those who do not want to use regex:

$data = filter_var($data, FILTER_SANITIZE_NUMBER_INT);

note: it works with phone numbers too.

You can use the OfType operator. It ignores null values in the source sequence. Just use the same type as MyProperty and it won't filter out anything else.

// given:
// public T MyProperty { get; }
var nonNullItems = list.Select(x => x.MyProperty).OfType<T>();

I would advise against this though. If you want to pick non-null values, what can be more explicit than saying you want "the MyProperties from the list that are not null"?

You can do one of the following:

<?php
    $data = 'My data';

    function menugen() {
        global $data;
        echo "[" . $data . "]";
    }

    menugen();

Or

<?php
    $data = 'My data';

    function menugen() {
        echo "[" . $GLOBALS['data'] . "]";
    }

    menugen();

That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).

EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'

check field execution_status

0 - Returns only those jobs that are not idle or suspended.
1 - Executing.
2 - Waiting for thread.
3 - Between retries.
4 - Idle.
5 - Suspended.
7 - Performing completion actions.

If you need the result of execution, check the field last_run_outcome

0 = Failed
1 = Succeeded
3 = Canceled
5 = Unknown

Node is used to represent tags in general. Divided to 3 types:

Attribute Note: is node which inside its has attributes. Exp: <p id=”123”></p>

Text Node: is node which between the opening and closing its have contian text content. Exp: <p>Hello</p>

Element Node : is node which inside its has other tags. Exp: <p><b></b></p>

Each node may be types simultaneously, not necessarily only of a single type.

Element is simply a element node.

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

That's why your example uses Active X, which bypasses the JavaScript security issues.

So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.

Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.

Just in addition to the above answers, for the question where and when you should call getLocationOnScreen?

For any information that is related to the view, will be available only after the view has been laid out(created) on the screen. So to get the location put your code inside view.post(Runnable) which is called after view has been laid out, like this:

view.post(new Runnable() {
            @Override
            public void run() {

               // This code will run when view created and rendered on screen

               // So as the answer to this question, you can put the code here
               int[] location = new int[2];
               myView.getLocationOnScreen(location);
               int x = location[0];
               int y = location[1];
            }
        });  

You may try this CSS. I have experienced it working always.

div {
  border-style: solid;
  padding: 5px;
}

table {
  width: 100%;
  word-break: break-all;
  border-style: solid;
}

<div style="width:200px;">
  <table>
    <tr>
      <th>Col 1</th>
      <th>Col 2</th>
      <th>Col 3</th>
      <th>Col 4</th>
      <th>Col 5</th>
    </tr>
    <tr>
      <td>data 1</td>
      <td>data 2</td>
      <td>data 3</td>
      <td>data 4</td>
      <td>data 5</td>
    </tr>
    <table>
</div>

HTML:

<div class="foo">
    /* whatever is required */
</div>

CSS:

.foo {
    top: 0;
    transition: top ease 0.5s;
}

.foo:hover{
    top: -10px;
}

This is just a basic transition to ease the div tag up by 10px when it is hovered on. The transition property's values can be edited along with the class.hover properties to determine how the transition works.

Missing ; after var_dump($row)

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

use mkdirs() instead of mkdir()..it worked for me :)

File folder = new File(Environment.getExternalStorageDirectory()+"/Saved CGPA");
if(!folder.exists()){
    if(folder.mkdirs())
    Toast.makeText(this, "New Folder Created", Toast.LENGTH_SHORT).show();
}

File sdCardFile = new File(Environment.getExternalStorageDirectory()+"/Saved CGPA/cgpa.html");

parent.location.reload();

This should work.

ReLU(x) also is equal to (x+abs(x))/2

If you actually want Yes and No buttons (and assuming WinForms):

void button_Click(object sender, EventArgs e)
{
    var message = "Yes or No?";
    var title = "Hey!";
    var result = MessageBox.Show(
        message,                  // the message to show
        title,                    // the title for the dialog box
        MessageBoxButtons.YesNo,  // show two buttons: Yes and No
        MessageBoxIcon.Question); // show a question mark icon

    // the following can be handled as if/else statements as well
    switch (result)
    {
    case DialogResult.Yes:   // Yes button pressed
        MessageBox.Show("You pressed Yes!");
        break;
    case DialogResult.No:    // No button pressed
        MessageBox.Show("You pressed No!");
        break;
    default:                 // Neither Yes nor No pressed (just in case)
        MessageBox.Show("What did you press?");
        break;
    }
}

Before trying to delete/rename any file, you must ensure that all the readers or writers (for ex: BufferedReader/InputStreamReader/BufferedWriter) are properly closed.

When you try to read/write your data from/to a file, the file is held by the process and not released until the program execution completes. If you want to perform the delete/rename operations before the program ends, then you must use the close() method that comes with the java.io.* classes.

In plain JS add { passive: false } as third argument

document.addEventListener('wheel', function(e) {
    e.preventDefault();
    doStuff(e);
}, { passive: false });

dynamic_cast uses RTTI. It can slow down your application, you can use modification of the visitor design pattern to achieve downcasting without RTTI http://arturx64.github.io/programming-world/2016/02/06/lazy-visitor.html

If you need that each div will have its own toggle and don't want clicks to affect other divs, do this:

Here's what I did to solve this...

<div [ngClass]="{'teaser': !teaser_1 }" (click)="teaser_1=!teaser_1">
...content...
</div>

<div [ngClass]="{'teaser': !teaser_2 }" (click)="teaser_2=!teaser_2">
...content...
</div>

<div [ngClass]="{'teaser': !teaser_3 }" (click)="teaser_3=!teaser_3">
...content...
</div>

it requires custom numbering which sucks, but it works.

mechanize for Java would be a good fit for this, and as Wadjy Essam mentioned it uses JSoup for the HMLT. mechanize is a stageful HTTP/HTML client that supports navigation, form submissions, and page scraping.

For those that are still experiencing problems, like I have(I am using Ubuntu 16.04), I had to put in the following commands in order to get some gems like bcrypt, pg, and others installed. They are all similar to the ones above except for one.

sudo apt-get install ruby-dev -y
sudo apt-get install libpq-dev -y
sudo apt-get install libmysqlclient-dev
sudo apt-get install build-essential patch -y

This allowed me to install gems like, PG, bcrypt, and recaptcha.

I was faces this issue but after change object into str, problem solved. str(fname).isalpha():

You might try changing this line in your persistence.xml from

<property name="hbm2ddl.auto" value="create"/>

to:

<property name="hibernate.hbm2ddl.auto" value="update"/>

This is supposed to maintain the schema to follow any changes you make to the Model each time you run the app.

Got this from JavaRanch

If you want the most recently added one, add a timestamp and select ordered in reverse order by highest timestamp, limit 1. If you want to go by ID, sort by ID. If you want to use the one you JUST added, use mysql_insert_id.

For historic reasons, I leave you the links to the last versions of ADT:

After that, you can update ADT plugin after 20140702 version. This answer was intended for the ones starting from zero.

3 Steps:

• Open "Repo Browser" (Use Link of yr parent folder) .
• Right click Choose "Add Folder".
• Browse to your folder.

The practical way is setting font-family to a value that is the specific name of the semibold version, such as

font-family: "Myriad pro Semibold"

if that’s the name. (Personally I use my own font listing tool, which runs on Internet Explorer only to see the fonts in my system by names as usable in CSS.)

In this approach, font-weight is not needed (and probably better not set).

Web browsers have been poor at implementing font weights by the book: they largely cannot find the specific weight version, except bold. The workaround is to include the information in the font family name, even though this is not how things are supposed to work.

Testing with Segoe UI, which often exists in different font weight versions on Windows systems, I was able to make Internet Explorer 9 select the proper version when using the logical approach (of using the font family name Segoe UI and different font-weight values), but it failed on Firefox 9 and Chrome 16 (only normal and bold work). On all of these browsers, for example, setting font-family: Segoe UI Light works OK.

I have just discovered the round function - it is in Python 2.7, not sure about 2.6. It takes a float and the number of dps as arguments, so round(22.55555, 2) gives the result 22.56.

Based on Rubens' solution, you need to enable Delayed Expansion of env variables (type "help setlocal" or "help cmd") so that the var is correctly evaluated in the loop:

@echo off
setlocal enabledelayedexpansion
set myvar=the list: 
for /r %%i In (*.sql) DO set myvar=!myvar! %%i,
echo %myvar%

Also consider the following restriction (MSDN):

The maximum individual environment variable size is 8192bytes.

in ruby for constantly using, add follow:

module Selenium
  module WebDriver
    class Element
      def select(value)
        self.find_elements(:tag_name => "option").find do |option|
          if option.text == value
            option.click
              return
           end
       end
    end
  end
end

and you will be able to select value:

browser.find_element(:xpath, ".//xpath").select("Value")

I ran into this while working on a .NET console app to read the PATH environment variable, and found that using System.Environment.GetEnvironmentVariable will expand the environment variables automatically.

I didn't want that to happen...that means folders in the path such as '%SystemRoot%\system32' were being re-written as 'C:\Windows\system32'. To get the un-expanded path, I had to use this:

string keyName = @"SYSTEM\CurrentControlSet\Control\Session Manager\Environment\";
string existingPathFolderVariable = (string)Registry.LocalMachine.OpenSubKey(keyName).GetValue("PATH", "", RegistryValueOptions.DoNotExpandEnvironmentNames);

Worked like a charm for me.

If the size of the array is known at compile time, you can use the structure size to determine the number of elements.

struct foo fooarr[10];

for(i = 0; i < sizeof(fooarr) / sizeof(struct foo); i++)
{
  do_something(fooarr[i].data);
}

If it is not known at compile time, you will need to store a size somewhere or create a special terminator value at the end of the array.

I have also faced this problem and the solution is:

1. open Solution Explore
2. double click on Program.cs file

I added this code again and my program ran accurately:

Application.Run(new PayrollSystem()); 
//File name this code removed by me accidentally.

You can do it by MXBeans

public class Check {
    public static void main(String[] args) {
        MemoryMXBean memBean = ManagementFactory.getMemoryMXBean() ;
        MemoryUsage heapMemoryUsage = memBean.getHeapMemoryUsage();

        System.out.println(heapMemoryUsage.getMax()); // max memory allowed for jvm -Xmx flag (-1 if isn't specified)
        System.out.println(heapMemoryUsage.getCommitted()); // given memory to JVM by OS ( may fail to reach getMax, if there isn't more memory)
        System.out.println(heapMemoryUsage.getUsed()); // used now by your heap
        System.out.println(heapMemoryUsage.getInit()); // -Xms flag

        // |------------------ max ------------------------| allowed to be occupied by you from OS (less than xmX due to empty survival space)
        // |------------------ committed -------|          | now taken from OS
        // |------------------ used --|                    | used by your heap

    }
}

But remember it is equivalent to Runtime.getRuntime() (took depicted schema from here)

memoryMxBean.getHeapMemoryUsage().getUsed()      <=> runtime.totalMemory() - runtime.freeMemory()
memoryMxBean.getHeapMemoryUsage().getCommitted() <=> runtime.totalMemory()
memoryMxBean.getHeapMemoryUsage().getMax()       <=> runtime.maxMemory()

from javaDoc

init - represents the initial amount of memory (in bytes) that the Java virtual machine requests from the operating system for memory management during startup. The Java virtual machine may request additional memory from the operating system and may also release memory to the system over time. The value of init may be undefined.

used - represents the amount of memory currently used (in bytes).

committed - represents the amount of memory (in bytes) that is guaranteed to be available for use by the Java virtual machine. The amount of committed memory may change over time (increase or decrease). The Java virtual machine may release memory to the system and committed could be less than init. committed will always be greater than or equal to used.

max - represents the maximum amount of memory (in bytes) that can be used for memory management. Its value may be undefined. The maximum amount of memory may change over time if defined. The amount of used and committed memory will always be less than or equal to max if max is defined. A memory allocation may fail if it attempts to increase the used memory such that used > committed even if used <= max would still be true (for example, when the system is low on virtual memory).

    +----------------------------------------------+
    +////////////////           |                  +
    +////////////////           |                  +
    +----------------------------------------------+

    |--------|
       init
    |---------------|
           used
    |---------------------------|
              committed
    |----------------------------------------------|
                        max

As additional note, maxMemory is less than -Xmx because there is necessity at least in one empty survival space, which can't be used for heap allocation.

also it is worth to to take a look at here and especially here

I like to start with a class like this class settings { public int X {get;set;} public string Y { get; set; } // repeat as necessary

 public settings()
 {
    this.X = defaultForX;
    this.Y = defaultForY;
    // repeat ...
 }
 public void Parse(Uri uri)
 {
    // parse values from query string.
    // if you need to distinguish from default vs. specified, add an appropriate property

 }

This has worked well on 100's of projects. You can use one of the many other parsing solutions to parse values.

Simplest solution and workaround:

<input name="toRent" type="radio" (click)="setToRentControl(false)">
<input name="toRent" type="radio" (click)="setToRentControl(true)">

setToRentControl(value){
    this.vm.toRent.updateValue(value);
    alert(value); //true/false
}

string str = "asasdkopaksdpoadks";
byte[] data = Encoding.ASCII.GetBytes(str);
MemoryStream stm = new MemoryStream(data, 0, data.Length);

First Declare a variable to store filenames (to use them later):

var myfiles = [];

Open File Dialog

$('#browseBtn').click(function() {
    $('<input type="file" multiple>').on('change', function () {
        myfiles = this.files; //save selected files to the array
        console.log(myfiles); //show them on console
    }).click();
});

i'm posting it, so it may help someone because there are no clear instructions on the internet to how to store filenames into an array!

$('#myDiv').click is better, because it separates JavaScript code from HTML. One must try to keep the page behaviour and structure different. This helps a lot.

To understand it better, run this following program (in jdk1.7.x) :

$ java -Xms1025k -Xmx1025k -XshowSettings:vm  MemoryTest

This will print jvm options and the used, free, total and maximum memory available in jvm.

public class MemoryTest {    
    public static void main(String args[]) {
                System.out.println("Used Memory   :  " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) + " bytes");
                System.out.println("Free Memory   : " + Runtime.getRuntime().freeMemory() + " bytes");
                System.out.println("Total Memory  : " + Runtime.getRuntime().totalMemory() + " bytes");
                System.out.println("Max Memory    : " + Runtime.getRuntime().maxMemory() + " bytes");            
        }
}

try this

df.rename(columns={ df.columns[1]: "your value" }, inplace = True)

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

You'll need the SQL Server Configuration Manager. Go to Sql Native Client Configuration, Select Client Protocols, Right Click on TCP/IP and set your default port there.

This question is old, but I wanted to add my two-cents. I read the question as " I want to run a query to my [my]SQL database and store the returned data as Pandas data structure [DataFrame]."

From the code it looks like you mean mysql database and assume you mean pandas DataFrame.

import MySQLdb as mdb
import pandas.io.sql as sql
from pandas import *

conn = mdb.connect('<server>','<user>','<pass>','<db>');
df = sql.read_frame('<query>', conn)

For example,

conn = mdb.connect('localhost','myname','mypass','testdb');
df = sql.read_frame('select * from testTable', conn)

This will import all rows of testTable into a DataFrame.

This is a known bug at MySQL.

bug 42996
bug 40477

As you can see this has been a known issue since 2008 and they have not fixed it yet!!!

WORK AROUND
You first need to create the database to import. It doesn't need any tables. Then you can import your database.

1. first start your MySQL command line (apply username and password if you need to)
   C:\>mysql -u user -p

2. Create your database and exit

   mysql> DROP DATABASE database;  
   mysql> CREATE DATABASE database;  
   mysql> Exit  
   

3. Import your selected database from the dump file
   C:\>mysql -u user -p -h localhost -D database -o < dumpfile.sql

You can replace localhost with an IP or domain for any MySQL server you want to import to. The reason for the DROP command in the mysql prompt is to be sure we start with an empty and clean database.

You can use box shadows to fake a border:

-webkit-box-shadow: 0px 0px 0px 1px rgba(255,0,0,1);
-moz-box-shadow: 0px 0px 0px 1px rgba(255,0,0,1);
box-shadow: 0px 0px 0px 1px rgba(255,0,0,1);

I finally managed to create a query that does exactly what i wanted to have:

A filtered nested boolean query. I am not sure why this is not documented. Maybe someone here can tell me?

Here is the query:

}

In pseudo-SQL:

SELECT * FROM /test/object
WHERE 
    ((name=foo AND name=bar) OR (info=foo AND info=bar))
AND state=1

Please keep in mind that it depends on your document field analysis and mappings how name=foo is internally handled. This can vary from a fuzzy to strict behavior.

"minimum_should_match": 1 says, that at least one of the should statements must be true.

This statements means that whenever there is a document in the resultset that contains has_image:1 it is boosted by factor 100. This changes result ordering.

"should": [
  {
    "match": {
      "has_image": {
        "query": 1,
        "boost": 100
      }
    }
   }
 ]

Have fun guys :)

PIE.htc worked for me great (http://css3pie.com/), but with one issue:

You should write absolute path to PIE.htc. It hasn't worked for me when I used relative path.

if you put the alter into a transaction the table should not be locked:

BEGIN;
  ALTER TABLE "public"."mytable" ALTER COLUMN "mycolumn" TYPE varchar(40);
COMMIT;

this worked for me blazing fast, few seconds on a table with more than 400k rows.

Instead of modifying the global profile you could create the .bash_profile in your default $HOME directory (e.g. C:\Users\WhateverUser\.bash_profile) with the following contents:

export HOME="C:\my\projects\dir"
cd "$HOME" # if you'd like it to be the starting dir of the git shell

When IE9 comes, it will be easier. A lot of the time though, you can switch the problem to one requiring :first-child and style the opposite side of the element (IE7+).

Sorry this is and old thread but some people would still need this I guess,

Note: I achieved this using Animate.css library for animating the fade.

I used your code and just added .hidden class (using bootstrap's hidden class) but you can still just define .hidden { opacity: 0; }

$(document).ready(function() {

/* Every time the window is scrolled ... */

$(window).scroll( function(){

/* Check the location of each desired element */
$('.hideme').each( function(i){

    var bottom_of_object = $(this).position().top + $(this).outerHeight();
    var bottom_of_window = $(window).scrollTop() + $(window).height();


    /* If the object is completely visible in the window, fade it it */
    if( bottom_of_window > bottom_of_object ){

        $(this).removeClass('hidden');
        $(this).addClass('animated fadeInUp');
    }    else {
            $(this).addClass('hidden');
               }

}); 
}); 
});

Another Note: Applying this to containers might cause it to be glitchy.

Returns last day of last month:

>>> import datetime
>>> datetime.datetime.now() - datetime.timedelta(days=datetime.datetime.now().day)
datetime.datetime(2020, 9, 30, 14, 13, 15, 67582)

Returns the same day last month:

>>> x = datetime.datetime.now() - datetime.timedelta(days=datetime.datetime.now().day)
>>> x.replace(day=datetime.datetime.now().day)
datetime.datetime(2020, 9, 7, 14, 22, 14, 362421)

Some time your $watch is calling dynamically and it will create its instances so you have to call deregistration function before your $watch function

if(myWatchFun)
  myWatchFun(); // it will destroy your previous $watch if any exist
myWatchFun = $scope.$watch("abc", function () {});

Try this:

$("#dp3").on("dp.change", function(e) {
    alert('hey');
});

In addition to the plt.axvline and plt.plot((x1, x2), (y1, y2)) OR plt.plot([x1, x2], [y1, y2]) as provided in the answers above, one can also use

plt.vlines(x_pos, ymin=y1, ymax=y2)

to plot a vertical line at x_pos spanning from y1 to y2 where the values y1 and y2 are in absolute data coordinates.

I think this timeout you are experiencing is actually part of TCP/IP and the solution is to just send empty messages once in a while.

I did a SQL query in a large number of OR (350). Postgres do it 437.80ms.

Now use IN:

My educated guess is that the memory use you are seeing is not from the page content, but rather from loading UIWebView and all of it's supporting WebKit libraries. I love the UIWebView control, but it is a 'heavy' control that pulls in a very large block of code.

This code is a large sub-set of the iOS Safari browser, and likely initializes a large body of static structures.

$start_date="17/02/2012";
$end_date="21/02/2012";
$date_from_user="19/02/2012";

function geraTimestamp($data)
{
    $partes = explode('/', $data); 
    return mktime(0, 0, 0, $partes[1], $partes[0], $partes[2]);
}


$startDatedt = geraTimestamp($start_date); 
$endDatedt = geraTimestamp($end_date);
$usrDatedt = geraTimestamp($date_from_user);

if (($usrDatedt >= $startDatedt) && ($usrDatedt <= $endDatedt))
{ 
    echo "Dentro";
}    
else
{
    echo "Fora";
}

On a client-side react application, there are a couple of ways of rendering a prop as a string with some html. One safer than the other...

1 - Define the prop as jsx (my preference)

const someProps = {
  greeting: {<div>Hello<a href="/${name_profile}">${name_profile}</a></div>}
}


const GreetingComopnent = props => (
  <p>{props.someProps.greeting}</p>
)

• The only requirement here is that whatever file is generating this prop needs to include React as a dependency (in case you're generating the prop's jsx in a helper file etc).

2 - Dangerously set the innerHtml

const someProps = {
  greeting: '<React.Fragment>Hello<a href="/${name_profile}">${name_profile}</a></React.Fragment>'
}

const GreetingComponent = props => {
  const innerHtml = { __html: props.someProps.greeting }
  return <p dangerouslySetInnerHtml={innerHtml}></p>
}

• This second approach is discouraged. Imagine an input field whose input value is rendered as a prop in this component. A user could enter a script tag in the input and the component that renders this input would execute this potentially malicious code. As such, this approach has the potential to introduce cross-site scripting vulnerabilities. For more information, refer to the official React docs

What about using a combination of some/findIndex and indexOf?

So something like this:

var array1 = ["apple","banana","orange"];
var array2 = ["grape", "pineapple"];

var found = array1.some(function(v) { return array2.indexOf(v) != -1; });

To make it more readable you could add this functionality to the Array object itself.

Array.prototype.indexOfAny = function (array) {
    return this.findIndex(function(v) { return array.indexOf(v) != -1; });
}

Array.prototype.containsAny = function (array) {
    return this.indexOfAny(array) != -1;
}

Note: If you'd want to do something with a predicate you could replace the inner indexOf with another findIndex and a predicate

You can do this in XAML easily enough:

<TextBlock>
  Hello <Bold>my</Bold> faithful <Underline>computer</Underline>.<Italic>You rock!</Italic>
</TextBlock>

The simplest way to put an image into a button:

<button onclick="myFunction()"><img src="your image name here.png"></button>

This will automatically resize the button to the size of the image.

All these answers with .ReadAllBytes(). Another, similar (I won't say duplicate, since they were trying to refactor their code) question was asked on SO here: Best way to read a large file into a byte array in C#?

A comment was made on one of the posts regarding .ReadAllBytes():

File.ReadAllBytes throws OutOfMemoryException with big files (tested with 630 MB file 
and it failed) – juanjo.arana Mar 13 '13 at 1:31

A better approach, to me, would be something like this, with BinaryReader:

public static byte[] FileToByteArray(string fileName)
{
    byte[] fileData = null;

    using (FileStream fs = File.OpenRead(fileName)) 
    { 
        var binaryReader = new BinaryReader(fs); 
        fileData = binaryReader.ReadBytes((int)fs.Length); 
    }
    return fileData;
}

But that's just me...

Of course, this all assumes you have the memory to handle the byte[] once it is read in, and I didn't put in the File.Exists check to ensure the file is there before proceeding, as you'd do that before calling this code.

The closest I could make is

select * FROM( SELECT *, ROW_NUMBER() over (ORDER BY ID ) as ct from [db].[dbo].[table] ) sub where ct > fromNumber  and ct <= toNumber

Which I guess similar to select * from [db].[dbo].[table] LIMIT 0, 10

How to open two instances of the same file side by side in Visual Studio 2019:

1. Open the file.

2. Click Window -> New Window.

3. A new window should be open with the same file.

4. Click on Window -> New Vertical Document Group.

Result:

Since the Except extension method operates on two IEumerables, it seems to me that it will be a O(n^2) operation. If performance is an issue (if say your lists are large), I'd suggest creating a HashSet from list1 and use HashSet's ExceptWith method.

There's a function to find a substring within a string (find), and a function to replace a particular range in a string with another string (replace), so you can combine those to get the effect you want:

bool replace(std::string& str, const std::string& from, const std::string& to) {
    size_t start_pos = str.find(from);
    if(start_pos == std::string::npos)
        return false;
    str.replace(start_pos, from.length(), to);
    return true;
}

std::string string("hello $name");
replace(string, "$name", "Somename");

In response to a comment, I think replaceAll would probably look something like this:

void replaceAll(std::string& str, const std::string& from, const std::string& to) {
    if(from.empty())
        return;
    size_t start_pos = 0;
    while((start_pos = str.find(from, start_pos)) != std::string::npos) {
        str.replace(start_pos, from.length(), to);
        start_pos += to.length(); // In case 'to' contains 'from', like replacing 'x' with 'yx'
    }
}

@AlexCuse I wanted to add this as comment to your answer but gave up after making multiple failed attempt to add newlines in comments.

That said, t1ID is unique in table_1 but that doesn't makes it unique in INFO table as well.

For example:

Table_1 has:
Id Field
1 A
2 B

Table_2 has:
Id Field
1 X
2 Y

INFO then can have:
t1ID t2ID field
1 1 some
1 2 data
2 1 in-each
2 2 row

So in INFO table to uniquely identify a row you need both t1ID and t2ID

With the ConstraintLayout v1.1.2, the dimension should be set to 0dp and then set the layout_constraintWidth_percent or layout_constraintHeight_percent attributes to a value between 0 and 1 like :

<!-- 50% width centered Button -->
<Button
    android:id="@+id/button"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintWidth_percent=".5" />

(You don't need to set app:layout_constraintWidth_default="percent" or app:layout_constraintHeight_default="percent" with ConstraintLayout 1.1.2 and following versions)

Did you try using t.Text?

Are you using .NET 3.5? You could use the ZipPackage class and related classes. Its more than just zipping up a file list because it wants a MIME type for each file you add. It might do what you want.

I'm currently using these classes for a similar problem to archive several related files into a single file for download. We use a file extension to associate the download file with our desktop app. One small problem we ran into was that its not possible to just use a third-party tool like 7-zip to create the zip files because the client side code can't open it -- ZipPackage adds a hidden file describing the content type of each component file and cannot open a zip file if that content type file is missing.

Doing some piggybacking off existing answers here:

public static string ToShortTimeSafe(this TimeSpan timeSpan)
{
    return new DateTime().Add(timeSpan).ToShortTimeString();
} 

public static string ToShortTimeSafe(this TimeSpan? timeSpan)
{
    return timeSpan == null ? string.Empty : timeSpan.Value.ToShortTimeSafe();
}

After following the instructions in the other answers, I needed to strip the version from the map file for this to work for me.

Example: Rename

jquery-1.9.1.min.map

to

Invoice USD

Qty Rate(count) Value (sum) 300 0.000 000.000 1000 0.385 385.000

Average Rate Count should Exclude 0.000 rate

I was trying to solve the problem of being able to iterate over several different text arrays all of which are stored within a memory resident database that is a large struct.

The following was worked out using Visual Studio 2017 Community Edition on an MFC test application. I am including this as an example as this posting was one of several that I ran across that provided some help yet were still insufficient for my needs.

The struct containing the memory resident data looked something like the following. I have removed most of the elements for the sake of brevity and have also not included the Preprocessor defines used (the SDK in use is for C as well as C++ and is old).

What I was interested in doing is having iterators for the various WCHAR two dimensional arrays which contained text strings for mnemonics.

typedef struct  tagUNINTRAM {
    // stuff deleted ...
    WCHAR   ParaTransMnemo[MAX_TRANSM_NO][PARA_TRANSMNEMO_LEN]; /* prog #20 */
    WCHAR   ParaLeadThru[MAX_LEAD_NO][PARA_LEADTHRU_LEN];   /* prog #21 */
    WCHAR   ParaReportName[MAX_REPO_NO][PARA_REPORTNAME_LEN];   /* prog #22 */
    WCHAR   ParaSpeMnemo[MAX_SPEM_NO][PARA_SPEMNEMO_LEN];   /* prog #23 */
    WCHAR   ParaPCIF[MAX_PCIF_SIZE];            /* prog #39 */
    WCHAR   ParaAdjMnemo[MAX_ADJM_NO][PARA_ADJMNEMO_LEN];   /* prog #46 */
    WCHAR   ParaPrtModi[MAX_PRTMODI_NO][PARA_PRTMODI_LEN];  /* prog #47 */
    WCHAR   ParaMajorDEPT[MAX_MDEPT_NO][PARA_MAJORDEPT_LEN];    /* prog #48 */
    //  ... stuff deleted
} UNINIRAM;

The current approach is to use a template to define a proxy class for each of the arrays and then to have a single iterator class that can be used to iterate over a particular array by using a proxy object representing the array.

A copy of the memory resident data is stored in an object that handles reading and writing the memory resident data from/to disk. This class, CFilePara contains the templated proxy class (MnemonicIteratorDimSize and the sub class from which is it is derived, MnemonicIteratorDimSizeBase) and the iterator class, MnemonicIterator.

The created proxy object is attached to an iterator object which accesses the necessary information through an interface described by a base class from which all of the proxy classes are derived. The result is to have a single type of iterator class which can be used with several different proxy classes because the different proxy classes all expose the same interface, the interface of the proxy base class.

The first thing was to create a set of identifiers which would be provided to a class factory to generate the specific proxy object for that type of mnemonic. These identifiers are used as part of the user interface to identify the particular provisioning data the user is interested in seeing and possibly modifying.

const static DWORD_PTR dwId_TransactionMnemonic = 1;
const static DWORD_PTR dwId_ReportMnemonic = 2;
const static DWORD_PTR dwId_SpecialMnemonic = 3;
const static DWORD_PTR dwId_LeadThroughMnemonic = 4;

The Proxy Class

The templated proxy class and its base class are as follows. I needed to accommodate several different kinds of wchar_t text string arrays. The two dimensional arrays had different numbers of mnemonics, depending on the type (purpose) of the mnemonic and the different types of mnemonics were of different maximum lengths, varying between five text characters and twenty text characters. Templates for the derived proxy class was a natural fit with the template requiring the maximum number of characters in each mnemonic. After the proxy object is created, we then use the SetRange() method to specify the actual mnemonic array and its range.

// proxy object which represents a particular subsection of the
// memory resident database each of which is an array of wchar_t
// text arrays though the number of array elements may vary.
class MnemonicIteratorDimSizeBase
{
    DWORD_PTR  m_Type;

public:
    MnemonicIteratorDimSizeBase(DWORD_PTR x) { }
    virtual ~MnemonicIteratorDimSizeBase() { }

    virtual wchar_t *begin() = 0;
    virtual wchar_t *end() = 0;
    virtual wchar_t *get(int i) = 0;
    virtual int ItemSize() = 0;
    virtual int ItemCount() = 0;

    virtual DWORD_PTR ItemType() { return m_Type; }
};

template <size_t sDimSize>
class MnemonicIteratorDimSize : public MnemonicIteratorDimSizeBase
{
    wchar_t    (*m_begin)[sDimSize];
    wchar_t    (*m_end)[sDimSize];

public:
    MnemonicIteratorDimSize(DWORD_PTR x) : MnemonicIteratorDimSizeBase(x), m_begin(0), m_end(0) { }
    virtual ~MnemonicIteratorDimSize() { }

    virtual wchar_t *begin() { return m_begin[0]; }
    virtual wchar_t *end() { return m_end[0]; }
    virtual wchar_t *get(int i) { return m_begin[i]; }

    virtual int ItemSize() { return sDimSize; }
    virtual int ItemCount() { return m_end - m_begin; }

    void SetRange(wchar_t (*begin)[sDimSize], wchar_t (*end)[sDimSize]) {
        m_begin = begin; m_end = end;
    }

};

The Iterator Class

The iterator class itself is as follows. This class provides just basic forward iterator functionality which is all that is needed at this time. However I expect that this will change or be extended when I need something additional from it.

class MnemonicIterator
{
private:
    MnemonicIteratorDimSizeBase   *m_p;  // we do not own this pointer. we just use it to access current item.
    int      m_index;                    // zero based index of item.
    wchar_t  *m_item;                    // value to be returned.

public:
    MnemonicIterator(MnemonicIteratorDimSizeBase *p) : m_p(p) { }
    ~MnemonicIterator() { }

    // a ranged for needs begin() and end() to determine the range.
    // the range is up to but not including what end() returns.
    MnemonicIterator & begin() { m_item = m_p->get(m_index = 0); return *this; }                 // begining of range of values for ranged for. first item
    MnemonicIterator & end() { m_item = m_p->get(m_index = m_p->ItemCount()); return *this; }    // end of range of values for ranged for. item after last item.
    MnemonicIterator & operator ++ () { m_item = m_p->get(++m_index); return *this; }            // prefix increment, ++p
    MnemonicIterator & operator ++ (int i) { m_item = m_p->get(m_index++); return *this; }       // postfix increment, p++
    bool operator != (MnemonicIterator &p) { return **this != *p; }                              // minimum logical operator is not equal to
    wchar_t * operator *() const { return m_item; }                                              // dereference iterator to get what is pointed to
};

The proxy object factory determines which object to created based on the mnemonic identifier. The proxy object is created and the pointer returned is the standard base class type so as to have a uniform interface regardless of which of the different mnemonic sections are being accessed. The SetRange() method is used to specify to the proxy object the specific array elements the proxy represents and the range of the array elements.

CFilePara::MnemonicIteratorDimSizeBase * CFilePara::MakeIterator(DWORD_PTR x)
{
    CFilePara::MnemonicIteratorDimSizeBase  *mi = nullptr;

    switch (x) {
    case dwId_TransactionMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_TRANSMNEMO_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_TRANSMNEMO_LEN>(x);
            mk->SetRange(&m_Para.ParaTransMnemo[0], &m_Para.ParaTransMnemo[MAX_TRANSM_NO]);
            mi = mk;
        }
        break;
    case dwId_ReportMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_REPORTNAME_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_REPORTNAME_LEN>(x);
            mk->SetRange(&m_Para.ParaReportName[0], &m_Para.ParaReportName[MAX_REPO_NO]);
            mi = mk;
        }
        break;
    case dwId_SpecialMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_SPEMNEMO_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_SPEMNEMO_LEN>(x);
            mk->SetRange(&m_Para.ParaSpeMnemo[0], &m_Para.ParaSpeMnemo[MAX_SPEM_NO]);
            mi = mk;
        }
        break;
    case dwId_LeadThroughMnemonic:
        {
            CFilePara::MnemonicIteratorDimSize<PARA_LEADTHRU_LEN> *mk = new CFilePara::MnemonicIteratorDimSize<PARA_LEADTHRU_LEN>(x);
            mk->SetRange(&m_Para.ParaLeadThru[0], &m_Para.ParaLeadThru[MAX_LEAD_NO]);
            mi = mk;
        }
        break;
    }

    return mi;
}

Using the Proxy Class and Iterator

The proxy class and its iterator are used as shown in the following loop to fill in a CListCtrl object with a list of mnemonics. I am using std::unique_ptr so that when the proxy class i not longer needed and the std::unique_ptr goes out of scope, the memory will be cleaned up.

What this source code does is to create a proxy object for the array within the struct which corresponds to the specified mnemonic identifier. It then creates an iterator for that object, uses a ranged for to fill in the CListCtrl control and then cleans up. These are all raw wchar_t text strings which may be exactly the number of array elements so we copy the string into a temporary buffer in order to ensure that the text is zero terminated.

    std::unique_ptr<CFilePara::MnemonicIteratorDimSizeBase> pObj(pFile->MakeIterator(m_IteratorType));
    CFilePara::MnemonicIterator pIter(pObj.get());  // provide the raw pointer to the iterator who doesn't own it.

    int i = 0;    // CListCtrl index for zero based position to insert mnemonic.
    for (auto x : pIter)
    {
        WCHAR szText[32] = { 0 };     // Temporary buffer.

        wcsncpy_s(szText, 32, x, pObj->ItemSize());
        m_mnemonicList.InsertItem(i, szText);  i++;
    }

If all you need is the ios 8 code, this should do it.

 - (BOOL)application:(UIApplication *)application       didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
       [application registerUserNotificationSettings: [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound  | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)  categories:nil]];

       [application registerForRemoteNotifications];
}

 return YES;
}

You can use parameters like that

<jsp:include page='about.jsp'>
    <jsp:param name="articleId" value=""/>
</jsp:include>

and

in about.jsp you can take the paramter

<%String leftAds = request.getParameter("articleId");%>

wxLua has three sleep functions:

local wx = require 'wx'
wx.wxSleep(12)   -- sleeps for 12 seconds
wx.wxMilliSleep(1200)   -- sleeps for 1200 milliseconds
wx.wxMicroSleep(1200)   -- sleeps for 1200 microseconds (if the system supports such resolution)

+1 to @MartinNuc, you can run the mysql client in batch mode and then you won't see the long stream of "OK" lines.

The amount of time it takes to import a given SQL file depends on a lot of things. Not only the size of the file, but the type of statements in it, how powerful your server server is, and how many other things are running at the same time.

@MartinNuc says he can load 4GB of SQL in 4-5 minutes, but I have run 0.5 GB SQL files and had it take 45 minutes on a smaller server.

We can't really guess how long it will take to run your SQL script on your server.

Re your comment,

@MartinNuc is correct you can choose to make the mysql client print every statement. Or you could open a second session and run mysql> SHOW PROCESSLIST to see what's running. But you probably are more interested in a "percentage done" figure or an estimate for how long it will take to complete the remaining statements.

Sorry, there is no such feature. The mysql client doesn't know how long it will take to run later statements, or even how many there are. So it can't give a meaningful estimate for how much time it will take to complete.

I came across this question when I was trying similar things.

Like you, I am using python 2.7 on my old iMac (OS X 10.6.8), I met the problem too, using urllib2.urlopen :

urlopen error [SSL: CERTIFICATE_VERIFY_FAILED]

My programs were running fine without SSL certificate problems and suddently (after dowloading programs), they crashed with this SSL error.

The problem was the version of python used :

1. No problem with https://www.python.org/downloads and python-2.7.9-macosx10.6.pkg

2. problem with the one instaled by Homebrew tool : "brew install python", version located in /usr/local/bin.

A chapter, called Certificate verification and OpenSSL [CHANGED for Python 2.7.9], in /Applications/Python 2.7/ReadMe.rtf explains the problem with many details.

So, check, download and put in your PATH the right version of python.

If the server accessible with RPC (basically, if you can access a shared folder on it), you could free some memory and thus let the RDP service work properly. The following windows native commands can be used:

To get the list of memory consuming tasks:

tasklist /S <remote_server> /V /FI "MEMUSAGE gt 10000"

To kill a task by its name:

taskkill /S <remote_server> /IM <process_image_name> /F

To show the list of desktop sessions:

qwinsta.exe /SERVER:<remote_server>

To close an old abandoned desktop session:

logoff <session_id> /SERVER:<remote_server> 

After some memory is freed, the RDP should start working.

if you're using SQL Server,

dateadd(DAY,0, datediff(day,0, created)) will return the day created

for example, if the sale created on '2009-11-02 06:12:55.000', dateadd(DAY,0, datediff(day,0, created)) return '2009-11-02 00:00:00.000'

select sum(amount) as total, dateadd(DAY,0, datediff(day,0, created)) as created
from sales
group by dateadd(DAY,0, datediff(day,0, created))

Chaos is spot on, though for these sorts of questions you should check out the Jquery Documentation online - it really is quite comprehensive. The feature you are after is called 'jquery selectors'

Generally you do $('#ID').val() - the .afterwards can do a number of things on the element that is returned from the selector. You can also select all of the elements on a certain class and do something to each of them. Check out the documentation for some good examples.

You need to add the python executable path to your Window's PATH variable.

1. From the desktop, right-click My Computer and click Properties.
2. In the System Properties window, click on the Advanced tab.
3. In the Advanced section, click the Environment Variables button.
4. Highlight the Path variable in the Systems Variable section and click the Edit button.
5. Add the path of your python executable(c:\Python27\). Each different directory is separated with a semicolon. (Note: do not put spaces between elements in the PATH. Your addition to the PATH should read ;c:\Python27 NOT ; C\Python27)
6. Apply the changes. You might need to restart your system, though simply restarting cmd.exe should be sufficient.
7. Launch cmd and try again. It should work.

If you have GNU coreutils installed, consider %!unexpand --first-only or for 4-space tabs, consider %!unexpand -t 4 --first-only (--first-only is present just in case you were accidentally invoking unexpand with --all).

Note that this will only replace the spaces preceding the prescribed tab stops, not the spaces that follow them; you will see no visual difference in vim unless you display tabs more literally; for example, my ~/.vimrc contains set list listchars=tab:?? (I suspect this is why you thought unexpand didn't work).

By using to_string

print(df.Name.to_string(index=False))

Disclaimer: this is an update to Cascabel's answer, which I'm writing to save the curious some time.

I tried in vain to replicate (in Git 2.0.1) the remote HEAD is ambiguous message that Cascabel mentions in his answer; so I did a bit of digging (by cloning https://github.com/git/git and searching the log). It used to be that

Determining HEAD is ambiguous since it is done by comparing SHA1s.

In the case of multiple matches we return refs/heads/master if it
matches, else we return the first match we encounter. builtin-remote
needs all matches returned to it, so add a flag for it to request such.

(Commit 4229f1fa325870d6b24fe2a4c7d2ed5f14c6f771, dated Feb 27, 2009, found with git log --reverse --grep="HEAD is ambiguous")

However, the ambiguity in question has since been lifted:

One long-standing flaw in the pack transfer protocol used by "git
clone" was that there was no way to tell the other end which branch
"HEAD" points at, and the receiving end needed to guess.  A new
capability has been defined in the pack protocol to convey this
information so that cloning from a repository with more than one
branches pointing at the same commit where the HEAD is at now
reliably sets the initial branch in the resulting repository.

(Commit 9196a2f8bd46d36a285bdfa03b4540ed3f01f671, dated Nov 8, 2013, found with git log --grep="ambiguous" --grep="HEAD" --all-match)

Edit (thanks to torek):

$ git name-rev --name-only 9196a2f8bd46d36a285bdfa03b4540ed3f01f671
tags/v1.8.4.3~3

This means that, if you're using Git v1.8.4.3 or later, you shouldn't run into any ambiguous-remote-HEAD problem.

The very first alias I made once I started customizing my profile in PowerShell was 'which'.

New-Alias which get-command

To add this to your profile, type this:

"`nNew-Alias which get-command" | add-content $profile

The `n at the start of the last line is to ensure it will start as a new line.

Here's the C# integrated syntax version:

var items =
    from list in listOfList
    from item in list
    select item;

The spring configuration precedence is as follows.

1. ServletConfig init Parameter
2. ServletContext init parameter
3. JNDI attributes
4. System.getProperties()

So your configuration will be overridden at the command-line if you wish to do that. But the recommendation is to avoid overriding, though you can use multiple profiles.

array_key_exists() is SLOW compared to isset(). A combination of these two (see below code) would help.

It takes the performance advantage of isset() while maintaining the correct checking result (i.e. return TRUE even when the array element is NULL)

if (isset($a['element']) || array_key_exists('element', $a)) {
       //the element exists in the array. write your code here.
}

The benchmarking comparison: (extracted from below blog posts).

array_key_exists() only : 205 ms
isset() only : 35ms
isset() || array_key_exists() : 48ms

See http://thinkofdev.com/php-fast-way-to-determine-a-key-elements-existance-in-an-array/ and http://thinkofdev.com/php-isset-and-multi-dimentional-array/

for detailed discussion.

You can change it directly in styles.xml file \app\src\main\res\values\styles.xml

This work on older versions, I was changing it in KitKat and come here.

You're right, it's localhost\SQLEXPRESS (just no $) and yes, it's the same for both 2005 and 2008 express versions.

List<string> items = new List<string>();

items.Find(p => p == "blah");

or

items.Find(p => p.Contains("b"));

but this allows you to define what you are looking for via a match predicate...

I guess if you are talking linqToSql then:

example looking for Account...

DataContext dc = new DataContext();

Account item = dc.Accounts.FirstOrDefault(p => p.id == 5);

If you need to make sure that there is only 1 item (throws exception when more than 1)

DataContext dc = new DataContext();

Account item = dc.Accounts.SingleOrDefault(p => p.id == 5);

you can render the page in express more easily

 var app   = require('express')();    
    app.set('views', path.join(__dirname, 'views'));
    app.set('view engine', 'jade');
 
    app.get('/signup',function(req,res){      
    res.sendFile(path.join(__dirname,'/signup.html'));
    });

so if u request like http://127.0.0.1:8080/signup that it will render signup.html page under views folder.

Initialize again select2 by new id or class like below

when the page load

$(".mynames").select2();

call again when came by ajax after success ajax function

$(".names").select2();

You have your ssh clone statement wrong: git clone username [email protected]:root/test.git

That statement would try to clone a repository named username into the location relative to your current path, [email protected]:root/test.git.

You want to leave out username:

git clone [email protected]:root/test.git
