Workstation has some features that Player lacks, such as teams (groups of VMs connected by private LAN segments) and multi-level snapshot trees. It's aimed at power users and developers; they even have some hooks for using a debugger on the host to debug code in the VM (including kernel-level stuff). The core technology is the same, though.

It sounds to me as if you actually mean "linux guests" and not "linux hosts".

But in any case, I suspect you did not install the VMWare Tools: doubleclick on that icon on the Desktop that can be seen on your screenshot. It will install some drivers that communicate with VMWare that, among other things, allow to adjust the screen resolution dynamically.

When the installation process is finished, you'll most likely have to reboot the VM.

I don't know why but version 3.6 of DG_Readiness_Tool didn't work for me. After I restarted my laptop problem still persisted. I was looking for solution and finally I came across version 3.7 of the tool and this time problem went away. Here you can find latest powershell script:

DG_Readiness_Tool_v3.7

You need to install some packages such as Unlocker, GuestOSx, etc.

Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.

For those of us who don't remember where we are on unix, or which SID we are using.
Pop this in your .profile.

<br>function CD
<br>{

random functions like borland complier

using namespace std;

int sys_random(int min, int max) {
   return (rand() % (max - min+1) + min);
}

void sys_randomize() {
    srand(time(0));
}

Using groupby you could split into two dataframes like

In [1047]: df1, df2 = [x for _, x in df.groupby(df['Sales'] < 30)]

In [1048]: df1
Out[1048]:
   A  Sales
2  7     30
3  6     40
4  1     50

In [1049]: df2
Out[1049]:
   A  Sales
0  3     10
1  4     20

Try the following:

for i = 1:4
    result = strcat('f',int2str(i));
end

If you use this for naming several files that your code generates, you are able to concatenate more parts to the name. For example, with the extension at the end and address at the beginning:

filename = strcat('c:\...\name',int2str(i),'.png'); 

Roman, if you want to do your layout in Java code (ViewGroup descendant), it is possible. The trick is that you have to implement both onMeasure and onLayout methods. The onMeasure gets called first and you need to "measure" the subview (effectively sizing it to the desired value) there. You need to size it again in the onLayout call. If you fail to do this sequence or fail to call setMeasuredDimension() at the end of your onMeasure code, you won't get results. Why is this designed in such complicated and fragile way is beyond me.

Use something like:

Array.prototype.indexOf.call(myHTMLSelector.classList, 'the-class');

Use String.Format with alignment values.

For example:

String.Format("|{0,5}|{1,5}|{2,5}|{3,5}|", arg0, arg1, arg2, arg3);

To create one formatted row.

Looking at the Laravel API:

Request::ip();

Internally, it uses the getClientIps method from the Symfony Request Object:

public function getClientIps()
{
    $clientIps = array();
    $ip = $this->server->get('REMOTE_ADDR');
    if (!$this->isFromTrustedProxy()) {
        return array($ip);
    }
    if (self::$trustedHeaders[self::HEADER_FORWARDED] && $this->headers->has(self::$trustedHeaders[self::HEADER_FORWARDED])) {
        $forwardedHeader = $this->headers->get(self::$trustedHeaders[self::HEADER_FORWARDED]);
        preg_match_all('{(for)=("?\[?)([a-z0-9\.:_\-/]*)}', $forwardedHeader, $matches);
        $clientIps = $matches[3];
    } elseif (self::$trustedHeaders[self::HEADER_CLIENT_IP] && $this->headers->has(self::$trustedHeaders[self::HEADER_CLIENT_IP])) {
        $clientIps = array_map('trim', explode(',', $this->headers->get(self::$trustedHeaders[self::HEADER_CLIENT_IP])));
    }
    $clientIps[] = $ip; // Complete the IP chain with the IP the request actually came from
    $ip = $clientIps[0]; // Fallback to this when the client IP falls into the range of trusted proxies
    foreach ($clientIps as $key => $clientIp) {
        // Remove port (unfortunately, it does happen)
        if (preg_match('{((?:\d+\.){3}\d+)\:\d+}', $clientIp, $match)) {
            $clientIps[$key] = $clientIp = $match[1];
        }
        if (IpUtils::checkIp($clientIp, self::$trustedProxies)) {
            unset($clientIps[$key]);
        }
    }
    // Now the IP chain contains only untrusted proxies and the client IP
    return $clientIps ? array_reverse($clientIps) : array($ip);
} 

For fromating output date use format. Second moment argument is for parsing - however if you omit it then you testDate will cause deprecation warning

Deprecation warning: value provided is not in a recognized RFC2822 or ISO format...

to omit this warning you should provide parsing format

to be more robust (tabulation, return…), I define:

function is_not_empty_string($str) {
    if (is_string($str) && trim($str, " \t\n\r\0") !== '')
        return true;
    else
        return false;
}

// code to test
$values = array(false, true, null, 'abc', '23', 23, '23.5', 23.5, '', ' ', '0', 0);
foreach ($values as $value) {
    var_export($value);
    if (is_not_empty_string($value)) 
        print(" is a none empty string!\n");
    else
        print(" is not a string or is an empty string\n");
}

sources:

• https://www.php.net/manual/en/function.is-string.php
• https://www.php.net/manual/en/function.trim.php

I want the all to resolve when all the chains have been resolved.

Sure, then just pass the promise of each chain into the all() instead of the initial promises:

$q.all([one.promise, two.promise, three.promise]).then(function() {
    console.log("ALL INITIAL PROMISES RESOLVED");
});

var onechain   = one.promise.then(success).then(success),
    twochain   = two.promise.then(success),
    threechain = three.promise.then(success).then(success).then(success);

$q.all([onechain, twochain, threechain]).then(function() {
    console.log("ALL PROMISES RESOLVED");
});

First, you can use direct indexing (with booleans vectors) instead of re-accessing column names if you are working with the same data frame; it will be safer as pointed out by Ista, and quicker to write and to execute. So what you will only need is:

var.out.bool <- !names(data) %in% c("iden", "name", "x_serv", "m_serv")

and then, simply reassign data:

data <- data[,var.out.bool] # or...
data <- data[,var.out.bool, drop = FALSE] # You will need this option to avoid the conversion to an atomic vector if there is only one column left

Second, quicker to write, you can directly assign NULL to the columns you want to remove:

data[c("iden", "name", "x_serv", "m_serv")] <- list(NULL) # You need list() to respect the target structure.

Finally, you can use subset(), but it cannot really be used in the code (even the help file warns about it). Specifically, a problem to me is that if you want to directly use the drop feature of susbset() you need to write without quotes the expression corresponding to the column names:

subset( data, select = -c("iden", "name", "x_serv", "m_serv") ) # WILL NOT WORK
subset( data, select = -c(iden, name, x_serv, m_serv) ) # WILL

As a bonus, here is small benchmark of the different options, that clearly shows that subset is the slower, and that the first, reassigning method is the faster:

                                        re_assign(dtest, drop_vec)  46.719  52.5655  54.6460  59.0400  1347.331
                                      null_assign(dtest, drop_vec)  74.593  83.0585  86.2025  94.0035  1476.150
               subset(dtest, select = !names(dtest) %in% drop_vec) 106.280 115.4810 120.3435 131.4665 65133.780
 subset(dtest, select = names(dtest)[!names(dtest) %in% drop_vec]) 108.611 119.4830 124.0865 135.4270  1599.577
                                  subset(dtest, select = -c(x, y)) 102.026 111.2680 115.7035 126.2320  1484.174

Code is below :

dtest <- data.frame(x=1:5, y=2:6, z = 3:7)
drop_vec <- c("x", "y")

null_assign <- function(df, names) {
  df[names] <- list(NULL)
  df
}

re_assign <- function(df, drop) {
  df <- df [, ! names(df) %in% drop, drop = FALSE]
  df
}

res <- microbenchmark(
  re_assign(dtest,drop_vec),
  null_assign(dtest,drop_vec),
  subset(dtest, select = ! names(dtest) %in% drop_vec),
  subset(dtest, select = names(dtest)[! names(dtest) %in% drop_vec]),
  subset(dtest, select = -c(x, y) ),
times=5000)

plt <- ggplot2::qplot(y=time, data=res[res$time < 1000000,], colour=expr)
plt <- plt + ggplot2::scale_y_log10() + 
  ggplot2::labs(colour = "expression") + 
  ggplot2::scale_color_discrete(labels = c("re_assign", "null_assign", "subset_bool", "subset_names", "subset_drop")) +
  ggplot2::theme_bw(base_size=16)
print(plt)

This does the trick:

function findAncestor (el, cls) {
    while ((el = el.parentElement) && !el.classList.contains(cls));
    return el;
}

The while loop waits until el has the desired class, and it sets el to el's parent every iteration so in the end, you have the ancestor with that class or null.

Here's a fiddle, if anyone wants to improve it. It won't work on old browsers (i.e. IE); see this compatibility table for classList. parentElement is used here because parentNode would involve more work to make sure that the node is an element.

There is another item where Fortran is different than C - and potentially faster. Fortran has better optimization rules than C. In Fortran, the evaluation order of an expressions is not defined, which allows the compiler to optimize it - if one wants to force a certain order, one has to use parentheses. In C the order is much stricter, but with "-fast" options, they are more relaxed and "(...)" are also ignored. I think Fortran has a way which lies nicely in the middle. (Well, IEEE makes the live more difficult as certain evaluation-order changes require that no overflows occur, which either has to be ignored or hampers the evaluation).

Another area of smarter rules are complex numbers. Not only that it took until C 99 that C had them, also the rules govern them is better in Fortran; since the Fortran library of gfortran is partially written in C but implements the Fortran semantics, GCC gained the option (which can also be used with "normal" C programs):

-fcx-fortran-rules Complex multiplication and division follow Fortran rules. Range reduction is done as part of complex division, but there is no checking whether the result of a complex multiplication or division is "NaN + I*NaN", with an attempt to rescue the situation in that case.

The alias rules mentioned above is another bonus and also - at least in principle - the whole-array operations, which if taken properly into account by the optimizer of the compiler, can lead faster code. On the contra side are that certain operation take more time, e.g. if one does an assignment to an allocatable array, there are lots of checks necessary (reallocate? [Fortran 2003 feature], has the array strides, etc.), which make the simple operation more complex behind the scenes - and thus slower, but makes the language more powerful. On the other hand, the array operations with flexible bounds and strides makes it easier to write code - and the compiler is usually better optimizing code than a user.

In total, I think both C and Fortran are about equally fast; the choice should be more which language does one like more or whether using the whole-array operations of Fortran and its better portability are more useful -- or the better interfacing to system and graphical-user-interface libraries in C.

Have a look on this tutorial on how to make dialogs.

The li element supports an onclick event.

I found in a class file outside the scope of the Page, the above way (which I always have used) didn't work.
I found a workaround in this "context" as follows:

HttpContext.Current.Session.Add("currentUser", appUser);

and

(AppUser) HttpContext.Current.Session["currentUser"]

Otherwise the compiler was expecting a string when I pointed the object at the session object.

 try{
      Integer.parseInt(string);
      return true;
}catch (Exception  e){
      return false;
}

or you can do it himself:

 for ( int i = 0; i < string.length; ++i ) {
      if ( !( string[i] >= '0' || string[i] <= '9' ) )
           return false;
 }
 return true;

Of course is also function isDigit

$st = $data->prepare("SELECT * FROM exampleWHERE example LIKE :search LIMIT 10"); 

Using regex for string replacement is significantly slower than using a string replace.
As demonstrated on JSPerf, you can have different levels of efficiency for creating a regex, but all of them are significantly slower than a simple string replace. The regex is slower because:

Fixed-string matches don't have backtracking, compilation steps, ranges, character classes, or a host of other features that slow down the regular expression engine. There are certainly ways to optimize regex matches, but I think it's unlikely to beat indexing into a string in the common case.

For a simple test run on the JS perf page, I've documented some of the results:

<script>_x000D_
// Setup_x000D_
  var startString = "xxxxxxxxxabcxxxxxxabcxx";_x000D_
  var endStringRegEx = undefined;_x000D_
  var endStringString = undefined;_x000D_
  var endStringRegExNewStr = undefined;_x000D_
  var endStringRegExNew = undefined;_x000D_
  var endStringStoredRegEx = undefined;      _x000D_
  var re = new RegExp("abc", "g");_x000D_
</script>_x000D_
_x000D_
<script>_x000D_
// Tests_x000D_
  endStringRegEx = startString.replace(/abc/g, "def") // Regex_x000D_
  endStringString = startString.replace("abc", "def", "g") // String_x000D_
  endStringRegExNewStr = startString.replace(new RegExp("abc", "g"), "def"); // New Regex String_x000D_
  endStringRegExNew = startString.replace(new RegExp(/abc/g), "def"); // New Regexp_x000D_
  endStringStoredRegEx = startString.replace(re, "def") // saved regex_x000D_
</script>

The results for Chrome 68 are as follows:

String replace:    9,936,093 operations/sec
Saved regex:       5,725,506 operations/sec
Regex:             5,529,504 operations/sec
New Regex String:  3,571,180 operations/sec
New Regex:         3,224,919 operations/sec

From the sake of completeness of this answer (borrowing from the comments), it's worth mentioning that .replace only replaces the first instance of the matched character. Its only possible to replace all instances with //g. The performance trade off and code elegance could be argued to be worse if replacing multiple instances name.replace(' ', '_').replace(' ', '_').replace(' ', '_'); or worse while (name.includes(' ')) { name = name.replace(' ', '_') }

Somewhat easy to make add or remove HTML5 validation to fieldsets.

 $('form').each(function(){

    // CLEAR OUT ALL THE HTML5 REQUIRED ATTRS
    $(this).find('.required').attr('required', false);

    // ADD THEM BACK TO THE CURRENT FIELDSET
    // I'M JUST USING A CLASS TO IDENTIFY REQUIRED FIELDS
    $(this).find('fieldset.current .required').attr('required', true);

    $(this).submit(function(){

        var current     = $(this).find('fieldset.current')
        var next        = $(current).next()

        // MOVE THE CURRENT MARKER
        $(current).removeClass('current');
        $(next).addClass('current');

        // ADD THE REQUIRED TAGS TO THE NEXT PART
        // NO NEED TO REMOVE THE OLD ONES
        // SINCE THEY SHOULD BE FILLED OUT CORRECTLY
        $(next).find('.required').attr('required', true);

    });

});

You can do summary(santa$Believe) and you will get the count for TRUE and FALSE

class Node:
    def __init__(self, wordList=None adjacencyList=None):
        self.wordList = wordList or []
        self.adjacencyList = adjacencyList or []

No, you can't change scrollbars placement without any additional issues.

You can change text-direction to right-to-left ( rtl ), but it also change text position inside block.

This code can helps you, but I not sure it works in all browsers and OS.

<element style="direction: rtl; text-align: left;" />

Update: The method mentioned in the original answer is deprecated, we should use the new way instead:

>>> import numpy as np
>>> x = [1,1,1,2,2,2,5,25,1,1]
>>> np.array(np.unique(x, return_counts=True)).T
    array([[ 1,  5],
           [ 2,  3],
           [ 5,  1],
           [25,  1]])

Original answer:

you can use scipy.stats.itemfreq

>>> from scipy.stats import itemfreq
>>> x = [1,1,1,2,2,2,5,25,1,1]
>>> itemfreq(x)
/usr/local/bin/python:1: DeprecationWarning: `itemfreq` is deprecated! `itemfreq` is deprecated and will be removed in a future version. Use instead `np.unique(..., return_counts=True)`
array([[  1.,   5.],
       [  2.,   3.],
       [  5.,   1.],
       [ 25.,   1.]])

You can use KVO in Swift, but only for dynamic properties of NSObject subclass. Consider that you wanted to observe the bar property of a Foo class. In Swift 4, specify bar as dynamic property in your NSObject subclass:

class Foo: NSObject {
    @objc dynamic var bar = 0
}

You can then register to observe changes to the bar property. In Swift 4 and Swift 3.2, this has been greatly simplified, as outlined in Using Key-Value Observing in Swift:

class MyObject {
    private var token: NSKeyValueObservation

    var objectToObserve = Foo()

    init() {
        token = objectToObserve.observe(\.bar) { [weak self] object, change in  // the `[weak self]` is to avoid strong reference cycle; obviously, if you don't reference `self` in the closure, then `[weak self]` is not needed
            print("bar property is now \(object.bar)")
        }
    }
}

Note, in Swift 4, we now have strong typing of keypaths using the backslash character (the \.bar is the keypath for the bar property of the object being observed). Also, because it's using the completion closure pattern, we don't have to manually remove observers (when the token falls out of scope, the observer is removed for us) nor do we have to worry about calling the super implementation if the key doesn't match. The closure is called only when this particular observer is invoked. For more information, see WWDC 2017 video, What's New in Foundation.

In Swift 3, to observe this, it's a bit more complicated, but very similar to what one does in Objective-C. Namely, you would implement observeValue(forKeyPath keyPath:, of object:, change:, context:) which (a) makes sure we're dealing with our context (and not something that our super instance had registered to observe); and then (b) either handle it or pass it on to the super implementation, as necessary. And make sure to remove yourself as an observer when appropriate. For example, you might remove the observer when it is deallocated:

In Swift 3:

class MyObject: NSObject {
    private var observerContext = 0

    var objectToObserve = Foo()

    override init() {
        super.init()

        objectToObserve.addObserver(self, forKeyPath: #keyPath(Foo.bar), options: [.new, .old], context: &observerContext)
    }

    deinit {
        objectToObserve.removeObserver(self, forKeyPath: #keyPath(Foo.bar), context: &observerContext)
    }

    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
        guard context == &observerContext else {
            super.observeValue(forKeyPath: keyPath, of: object, change: change, context: context)
            return
        }

        // do something upon notification of the observed object

        print("\(keyPath): \(change?[.newKey])")
    }

}

Note, you can only observe properties that can be represented in Objective-C. Thus, you cannot observe generics, Swift struct types, Swift enum types, etc.

For a discussion of the Swift 2 implementation, see my original answer, below.

Using the dynamic keyword to achieve KVO with NSObject subclasses is described in the Key-Value Observing section of the Adopting Cocoa Design Conventions chapter of the Using Swift with Cocoa and Objective-C guide:

Key-value observing is a mechanism that allows objects to be notified of changes to specified properties of other objects. You can use key-value observing with a Swift class, as long as the class inherits from the NSObject class. You can use these three steps to implement key-value observing in Swift.

1. Add the dynamic modifier to any property you want to observe. For more information on dynamic, see Requiring Dynamic Dispatch.

   class MyObjectToObserve: NSObject {
       dynamic var myDate = NSDate()
       func updateDate() {
           myDate = NSDate()
       }
   }
   

2. Create a global context variable.

   private var myContext = 0
   

3. Add an observer for the key-path, and override the observeValueForKeyPath:ofObject:change:context: method, and remove the observer in deinit.

   class MyObserver: NSObject {
       var objectToObserve = MyObjectToObserve()
       override init() {
           super.init()
           objectToObserve.addObserver(self, forKeyPath: "myDate", options: .New, context: &myContext)
       }
   
       override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
           if context == &myContext {
               if let newValue = change?[NSKeyValueChangeNewKey] {
                   print("Date changed: \(newValue)")
               }
           } else {
               super.observeValueForKeyPath(keyPath, ofObject: object, change: change, context: context)
           }
       }
   
       deinit {
           objectToObserve.removeObserver(self, forKeyPath: "myDate", context: &myContext)
       }
   }
   

[Note, this KVO discussion has subsequently been removed from the Using Swift with Cocoa and Objective-C guide, which has been adapted for Swift 3, but it still works as outlined at the top of this answer.]

It's worth noting that Swift has its own native property observer system, but that's for a class specifying its own code that will be performed upon observation of its own properties. KVO, on the other hand, is designed to register to observe changes to some dynamic property of some other class.

I ended up doing the following and it works.

public static string Serialize(object obj)
{
    using (MemoryStream memoryStream = new MemoryStream())
    {
        DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
        serializer.WriteObject(memoryStream, obj);
        return Encoding.UTF8.GetString(memoryStream.ToArray());
    }
}

public static object Deserialize(string xml, Type toType)
{
    using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
    {
        XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(memoryStream, Encoding.UTF8, new XmlDictionaryReaderQuotas(), null);
        DataContractSerializer serializer = new DataContractSerializer(toType);
        return serializer.ReadObject(reader);
    }

It seems that the major problem was in the Serialize function when calling stream.GetBuffer(). Calling stream.ToArray() appears to work.

There are many ways to get a path. See CurrentDirrectory mentioned. Also, you can get the full file name of your application by using Assembly.GetExecutingAssembly().Location and then use Path class to get a directory name.

Let us have List<Object> objectList which we want to cast to List<T>

public <T> List<T> list(Class<T> c, List<Object> objectList){        
    List<T> list = new ArrayList<>();       
    for (Object o : objectList){
        T t = c.cast(o);
        list.add(t);
    }
    return list;
}

Starting from this:

>>> lst = [1, 2, 3]
>>> print('\n'.join('{}: {}'.format(*k) for k in enumerate(lst)))
0: 1
1: 2
2: 3

You can get rid of the join by passing \n as a separator to print

>>> print(*('{}: {}'.format(*k) for k in enumerate(lst)), sep="\n")
0: 1
1: 2
2: 3

Now you see you could use map, but you'll need to change the format string (yuck!)

>>> print(*(map('{0[0]}: {0[1]}'.format, enumerate(lst))), sep="\n")
0: 1
1: 2
2: 3

or pass 2 sequences to map. A separate counter and no longer enumerate lst

>>> from itertools import count
>>> print(*(map('{}: {}'.format, count(), lst)), sep="\n")
0: 1
1: 2
2: 3

You can try this query to get stored procedures and functions:

SELECT name, type
FROM dbo.sysobjects
WHERE type IN (
    'P', -- stored procedures
    'FN', -- scalar functions 
    'IF', -- inline table-valued functions
    'TF' -- table-valued functions
)
ORDER BY type, name

I think this is the best and easiest way to do it:

if (!(isset($action) && ($action == "add" || $action == "delete")))

You Can try usimg

backgroundImage: url(process.env.PUBLIC_URL + "/      assets/image_location")

I faced the same problem when i upgraded my Xcode to 7.3 and it showed me the same error in every project. The simplest solution that i found was to just the remove the apple account from Xcode and add it again.

To remove just go to Xcode > Preferences > Select the account and click on - sign.

and to add click on + sign and add the apple ID corresponding to your app.

After you add the account your problem would be solved.. If in case this still doesn't work . Then perform a next step of regenerating the profile (just click edit and then generate ) and then downloading your provisioning profile again and run it. I bet that would work .

Hope this helps. All the best

Here is a worked-out solution based on the other suggestions:

#include <string>
#include <iostream>
#include <clocale>
#include <locale>
#include <vector>

int main() {
  std::setlocale(LC_ALL, "");
  const std::wstring ws = L"hëllö";
  const std::locale locale("");
  typedef std::codecvt<wchar_t, char, std::mbstate_t> converter_type;
  const converter_type& converter = std::use_facet<converter_type>(locale);
  std::vector<char> to(ws.length() * converter.max_length());
  std::mbstate_t state;
  const wchar_t* from_next;
  char* to_next;
  const converter_type::result result = converter.out(state, ws.data(), ws.data() + ws.length(), from_next, &to[0], &to[0] + to.size(), to_next);
  if (result == converter_type::ok or result == converter_type::noconv) {
    const std::string s(&to[0], to_next);
    std::cout <<"std::string =     "<<s<<std::endl;
  }
}

This will usually work for Linux, but will create problems on Windows.

Here is a guide on how to manually sign an APK. It includes info about the new apk-signer introduced in build-tools 24.0.3 (10/2016)

Automated Process:

Use this tool (uses the new apksigner from Google):

https://github.com/patrickfav/uber-apk-signer

^{Disclaimer: Im the developer :)}

Manual Process:

Step 1: Generate Keystore (only once)

You need to generate a keystore once and use it to sign your unsigned apk. Use the keytool provided by the JDK found in %JAVA_HOME%/bin/

keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app

Step 2 or 4: Zipalign

zipalign which is a tool provided by the Android SDK found in e.g. %ANDROID_HOME%/sdk/build-tools/24.0.2/ is a mandatory optimzation step if you want to upload the apk to the Play Store.

zipalign -p 4 my.apk my-aligned.apk

Note: when using the old jarsigner you need to zipalign AFTER signing. When using the new apksigner method you do it BEFORE signing (confusing, I know). Invoking zipalign before apksigner works fine because apksigner preserves APK alignment and compression (unlike jarsigner).

You can verify the alignment with

zipalign -c 4 my-aligned.apk

Step 3: Sign & Verify

Using build-tools 24.0.2 and older

Use jarsigner which, like the keytool, comes with the JDK distribution found in %JAVA_HOME%/bin/ and use it like so:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore my-app.apk my_alias_name

and can be verified with

jarsigner -verify -verbose my_application.apk

Using build-tools 24.0.3 and newer

Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files (See here and here for more details). Threfore Google implemented their own apk signer called apksigner (duh!) The script file can be found in %ANDROID_HOME%/sdk/build-tools/24.0.3/ (the .jar is in the /lib subfolder). Use it like this

apksigner sign --ks my.keystore my-app.apk --ks-key-alias alias_name

and can be verified with

apksigner verify my-app.apk

The official documentation can be found here.

The only option I can think of is using width:100%. If you want to have a padding on the input field too, than just place a container label around it, move the formatting to that label instead, while also specify the padding to the label. Input fields are rigid.

    public static Action<Func<TabPage, bool>> GetTabHider(this TabControl container) {
        if (container == null) throw new ArgumentNullException("container");

        var orderedCache = new List<TabPage>();
        var orderedEnumerator = container.TabPages.GetEnumerator();
        while (orderedEnumerator.MoveNext()) {
            var current = orderedEnumerator.Current as TabPage;
            if (current != null) {
                orderedCache.Add(current);
            }
        }

        return (Func<TabPage, bool> where) => {
            if (where == null) throw new ArgumentNullException("where");

            container.TabPages.Clear();
            foreach (TabPage page in orderedCache) {
                if (where(page)) {
                    container.TabPages.Add(page);
                }
            }
        };
    }

Used like this:

    var showOnly = this.TabContainer1.GetTabHider();
    showOnly((tab) => tab.Text != "tabPage1");

Original ordering is retained by retaining a reference to the anonymous function instance.

Based on suggestions from @jaimedash and @Old_Mortality I found a solution:

DF$Den <- ifelse(DF$Denial1 < 1 & !is.na(DF$Denial1) | DF$Denial2 < 1 &  
!is.na(DF$Denial2) | DF$Denial3 < 1 & !is.na(DF$Denial3), "0", "1")

Then to ensure a value of NA if all values of the conditional variables are NA:

DF$Den <- ifelse(is.na(DF$Denial1) & is.na(DF$Denial2) & is.na(DF$Denial3), 
NA, DF$Den)

I believe most of the points regarding the causes and remedies have been covered by all contributors in this thread. I just want to point out for my 'unresolved external' problem, it was caused by a datatype defined as macro that gets substituted differently than expected, which results in that incorrect type being supplied to the function in question, and since the function with type is never defined, it couldn't have been resolved. In particular, under C/C++ -> Language, there is an attribute called 'Treat WChar_t As Built in Type, which should have been defined as 'No (/Zc:wchar_t-)' but did not in my case.

For Java 7 you can simply omit the Class.forName() statement as it is not really required.

For Java 8 you cannot use the JDBC-ODBC Bridge because it has been removed. You will need to use something like UCanAccess instead. For more information, see

Manipulating an Access database from Java without ODBC

The only thing that worked in my case was by using david valentine code. Using Root Attr. in the Person class did not help.

I have this simple Xml:

<?xml version="1.0"?>
<personList>
 <Person>
  <FirstName>AAAA</FirstName>
  <LastName>BBB</LastName>
 </Person>
 <Person>
  <FirstName>CCC</FirstName>
  <LastName>DDD</LastName>
 </Person>
</personList>

C# class:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

De-Serialization C# code from a Main method:

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "personList";
xRoot.IsNullable = true;
using (StreamReader reader = new StreamReader(xmlFilePath))
{
List<Person> result = (List<Person>)(new XmlSerializer(typeof(List<Person>), xRoot)).Deserialize(reader);
 int numOfPersons = result.Count;
}  

I think this is what you are looking for:

df.drop('Region', axis=1).apply(lambda x: x.mean(), axis=1)

If you're downloading text then I'd recommend using the WebClient and get a streamreader to the text:

        WebClient web = new WebClient();
        System.IO.Stream stream = web.OpenRead("http://www.yoursite.com/resource.txt");
        using (System.IO.StreamReader reader = new System.IO.StreamReader(stream))
        {
            String text = reader.ReadToEnd();
        }

If this is taking a long time then it is probably a network issue or a problem on the web server. Try opening the resource in a browser and see how long that takes. If the webpage is very large, you may want to look at streaming it in chunks rather than reading all the way to the end as in that example. Look at http://msdn.microsoft.com/en-us/library/system.io.stream.read.aspx to see how to read from a stream.

Well the answer was sitting right in front of me the whole time.

In SQL Server Management Studio 2008 there is a Debug button in the toolbar. Set a break point in a query window to step through.

I dismissed this functionality at the beginning because I didn't think of stepping INTO the stored procedure, which you can do with ease.

SSMS basically does what FinnNK mentioned with the MSDN walkthrough but automatically.

So easy! Thanks for your help FinnNK.

Edit: I should add a step in there to find the stored procedure call with parameters I used SQL Profiler on my database.

UPDATE 06/10/2014: using div's inside a's is semantically correct in HTML5.

You'll need to choose between the following scenarios:

<a href="http://google.com">
    <div>
        Hello world
    </div>
</a>

which is semantically incorrect, but it will work.

<div style="cursor: pointer;" onclick="window.location='http://google.com';">
    Hello world
</div>

which is semantically correct but it involves using JS.

<a href="http://google.com">
    <span style="display: block;">
        Hello world
    </span>
</a>

which is semantically correct and works as expected but is not a div any more.

table 
{
    border-collapse: collapse;
}

will collapse all borders separating the table columns...

or try

<table cellspacing="0" style="border-spacing: 0;">

do all cell-spacing to 0 and border spacing 0 to achieve same.

have a fun!

As the question seems unclear, I'm sorry if this answer is not directly related to the original intent.

For those using Select2 version 4+ and according to official plugin documentation, .select2("enable")is not the way to go anymore for disabling the select box (not a single option of it). It will even be completely removed from version 4.1 onward.

Quoted directy from the documentation (see https://select2.org/upgrading/migrating-from-35#select2-enable):

Select2 will respect the disabled property of the underlying select element. In order to enable or disable Select2, you should call .prop('disabled', true/false) on the element. Support for the old methods will be completely removed in Select2 4.1.

So in the previous answer's example, it should be: $('select').prop(disabled,true);

As the dictionary documentation for python 2 and python 3 would tell you, in python 2 items returns a list, while iteritems returns a iterator.

In python 3, items returns a view, which is pretty much the same as an iterator.

If you are using python 2, you may want to user iteritems if you are dealing with large dictionaries and all you want to do is iterate over the items (not necessarily copy them to a list)

This is the simple version, obviously you'll want to add some error checking:

var obj = {};
var pairs = queryString.split('&');
for(i in pairs){
    var split = pairs[i].split('=');
    obj[decodeURIComponent(split[0])] = decodeURIComponent(split[1]);
}

If you want to do it from properties, you can do this by setting the Format property of DateTimePicker to DateTimePickerFormat.Time and ShowUpDown property to true. Also, customFormat can be set in properties.

As of v2, you can simply specify an array of values to correspond to a color for each bar via the backgroundColor property:

datasets: [{
  label: "My First dataset",
  data: [20, 59, 80, 81, 56, 55, 40],
  backgroundColor: ["red", "blue", "green", "blue", "red", "blue"], 
}],

This is also possible for the borderColor, hoverBackgroundColor, hoverBorderColor.

From the documentation on the Bar Chart Dataset Properties:

Some properties can be specified as an array. If these are set to an array value, the first value applies to the first bar, the second value to the second bar, and so on.

There has been enough answers on RUN and CMD. I just want to add a few words on ENTRYPOINT. CMD arguments can be overwritten by command line arguments, while ENTRYPOINT arguments are always used.

This article is a good source of information.

For *Unix based systems, you can check the ports used by a particular application by issueing the following command in the terminal

[~/.]$ netstat -tuplen

You will get the list of all the ports that are being currently held and used by their respective process ID's

try this:

var count_element = $('.element').length

Interesting that Firefox will stop further processing of JavaScript after the relocate function. Chrome and IE will continue to display any other alerts and then reload the page. Try it:

<script type="text/javascript">
    alert('foo');
    window.location.reload(true);
    alert('bar');
    window.location.reload(true);
    alert('foobar');
    window.location.reload(true);
</script>

The same problem arrised for me when I installed Kaliko CMS Nuget Package. When I removed it, it started working fine again. So, your problem could be because of a recently installed Nuget Package. Uninstall it and your solution will work just fine.

This is what worked for me, adapted from Adding HTTP Headers to WCF Calls

// Message inspector used to add the User-Agent HTTP Header to the WCF calls for Server
public class AddUserAgentClientMessageInspector : IClientMessageInspector
{
    public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, IClientChannel channel)
    {
        HttpRequestMessageProperty property = new HttpRequestMessageProperty();

        var userAgent = "MyUserAgent/1.0.0.0";

        if (request.Properties.Count == 0 || request.Properties[HttpRequestMessageProperty.Name] == null)
        {
            var property = new HttpRequestMessageProperty();
            property.Headers["User-Agent"] = userAgent;
            request.Properties.Add(HttpRequestMessageProperty.Name, property);
        }
        else
        {
            ((HttpRequestMessageProperty)request.Properties[HttpRequestMessageProperty.Name]).Headers["User-Agent"] = userAgent;
        }
        return null;
    }

    public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
    {
    }
}

// Endpoint behavior used to add the User-Agent HTTP Header to WCF calls for Server
public class AddUserAgentEndpointBehavior : IEndpointBehavior
{
    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        clientRuntime.MessageInspectors.Add(new AddUserAgentClientMessageInspector());
    }

    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    {
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }
}

After declaring these classes you can add the new behavior to your WCF client like this:

client.Endpoint.Behaviors.Add(new AddUserAgentEndpointBehavior());

the difference is that max-device-width is all screen's width and max-width means the space used by the browser to show the pages. But another important difference is the support of android browsers, in fact if u're going to use max-device-width this will work only in Opera, instead I'm sure that max-width will work for every kind of mobile browser (I had test it in Chrome, firefox and opera for ANDROID).

1. To extract a numeric value out of your string you can use these 2 functions (Assuming you have your value in cell 'A1'):

   =VALUE(REGEXEXTRACT(A1, "\d+"))

   This will get you a numeric value.

2. I've found no date add function in docs, but you can convert your date into internal date number and then add days number (If your value is in cell 'A2'):

   =DATEVALUE(A2) + 30

I hope this will help.

The window binding refers to a built-in object provided by the browser. It represents the browser window that contains the document. Calling its addEventListener method registers the second argument (callback function) to be called whenever the event described by its first argument occurs.

<p>Some paragraph.</p>
<script>
  window.addEventListener("click", () => {
    console.log("Test");
  });
</script>

Following points should be noted before select window or document to addEventListners

1. Most of the events are same for window or document but some events like resize, and other events related to loading, unloading, and opening/closing should all be set on the window.
2. Since window has the document it is good practice to use document to handle (if it can handle) since event will hit document first.
3. Internet Explorer doesn't respond to many events registered on the window,so you will need to use document for registering event.

You can use:

df.set_value('Row_index', 'Column_name', value)

set_valye is ~100 times faster than .ix method. It also better then use df['Row_index']['Column_name'] = value.

But since set_value is deprecated now so .iat/.at are good replacements.

For example if we have this data_frame

   A   B   C
0  1   8   4 
1  3   9   6
2  22 33  52

if we want to modify the value of the cell [0,"A"] we can do

df.iat[0,0] = 2

or df.at[0,'A'] = 2

You can use reflection to find all the get methods in your DAO objects and call the equivalent set method in the DTO. This will only work if all such methods exist. It should be easy to find example code for this.

If you need to check the same string often you can calculate the character occurrences up-front. This is an implementation that uses a bit array contained into a long array:

public class FastCharacterInStringChecker implements Serializable {
private static final long serialVersionUID = 1L;

private final long[] l = new long[1024]; // 65536 / 64 = 1024

public FastCharacterInStringChecker(final String string) {
    for (final char c: string.toCharArray()) {
        final int index = c >> 6;
        final int value = c - (index << 6);
        l[index] |= 1L << value;
    }
}

public boolean contains(final char c) {
    final int index = c >> 6; // c / 64
    final int value = c - (index << 6); // c - (index * 64)
    return (l[index] & (1L << value)) != 0;
}}

f = open('test.txt','r')
for line in f.xreadlines():
    print line
f.close()

This is much easier than you're making it. The text node will not have the literal string " " in it, it'll have have the corresponding character with code 160.

function replaceNbsps(str) {
  var re = new RegExp(String.fromCharCode(160), "g");
  return str.replace(re, " ");
}

textNode.nodeValue = replaceNbsps(textNode.nodeValue);

UPDATE

Even easier:

Mark Longair's answer (using git show) is close to what is desired in the question. However, it also includes the commit pointed at by the tag, along with the full patch for that commit. Since the commit can be somewhat unrelated to the tag (it's only one commit that the tag is attempting to capture), this may be undesirable. I believe the following is a bit nicer:

for t in `git tag -l`; do git cat-file -p `git rev-parse $t`; done

WinSCp now supports S3 protocol

First, make sure your AWS user with S3 access permissions has an “Access key ID” created. You also have to know the “Secret access key”. Access keys are created and managed on Users page of IAM Management Console.

Make sure New site node is selected.

On the New site node, select Amazon S3 protocol.

Enter your AWS user Access key ID and Secret access key

Save your site settings using the Save button.

Login using the Login button.

The following simplified code, based on the accepted answer above, worked for me:

public class GetSync {
    public static String ISO_FORMAT = "yyyy-MM-dd'T'HH:mm:ss.SSS zzz";
    private static final TimeZone utc = TimeZone.getTimeZone("UTC");
    private static final SimpleDateFormat isoFormatter = new SimpleDateFormat(ISO_FORMAT);
    static {
        isoFormatter.setTimeZone(utc);
    }

    public static String now() {
        return isoFormatter.format(new Date()).toString();
    }
}

I hope this helps somebody.

It was used as a pattern to store in memory as a series of hex bytes (0xde, 0xad, 0xbe, 0xef). You could see if memory was corrupted because of hardware failure, buffer overruns, etc.

Unlike jQuery in order to read raw JSON you will need to decode it in PHP.

print_r(json_decode(file_get_contents("php://input"), true));

php://input is a read-only stream that allows you to read raw data from the request body.

$_POST is form variables, you will need to switch to form radiobutton in postman then use:

foo=bar&foo2=bar2

To post raw json with jquery:

$.ajax({
    "url": "/rest/index.php",
    'data': JSON.stringify({foo:'bar'}),
    'type': 'POST',
    'contentType': 'application/json'
});

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

For what it's worth, if you are editing this file, you can probably highlight all the lines and use your un-tab button.

• In Vim, use Shift + V to highlight the lines, then press <<
• If you're on a Mac, then you can use Atom, Sublime Text, etc., then highlight with your mouse and then press Shift + Tab

I am not sure if there is some requirement that this must be done from the command line. If so, then :thumbs-up: to the accepted answer! =)

Btw "date" is usually tagged as "obsolete / deprecated" (I dont know exactly why) - something about it is wrote there Java: Why is the Date constructor deprecated, and what do I use instead?

It looks like it's a problem of the constructor only- way via new Date(int year, int month, int day), recommended way is via Calendar and set params separately .. (Calendar cal = Calendar.getInstance(); )

IMHO Lookup tables is the way to go, with referential integrity. But only if you avoid "Evil Magic Numbers" by following an example such as this one: Generate enum from a database lookup table using T4

I think it's important to point out and to know that if the destination slice (the slice you append to) has sufficient capacity, the append will happen "in-place", by reslicing the destination (reslicing to increase its length in order to be able to accommodate the appendable elements).

This means that if the destination was created by slicing a bigger array or slice which has additional elements beyond the length of the resulting slice, they may get overwritten.

To demonstrate, see this example:

a := [10]int{1, 2}
fmt.Printf("a: %v\n", a)

x, y := a[:2], []int{3, 4}
fmt.Printf("x: %v, y: %v\n", x, y)
fmt.Printf("cap(x): %v\n", cap(x))

x = append(x, y...)
fmt.Printf("x: %v\n", x)

fmt.Printf("a: %v\n", a)

Output (try it on the Go Playground):

a: [1 2 0 0 0 0 0 0 0 0]
x: [1 2], y: [3 4]
cap(x): 10
x: [1 2 3 4]
a: [1 2 3 4 0 0 0 0 0 0]

We created a "backing" array a with length 10. Then we create the x destination slice by slicing this a array, y slice is created using the composite literal []int{3, 4}. Now when we append y to x, the result is the expected [1 2 3 4], but what may be surprising is that the backing array a also changed, because capacity of x is 10 which is sufficient to append y to it, so x is resliced which will also use the same a backing array, and append() will copy elements of y into there.

If you want to avoid this, you may use a full slice expression which has the form

a[low : high : max]

which constructs a slice and also controls the resulting slice's capacity by setting it to max - low.

See the modified example (the only difference is that we create x like this: x = a[:2:2]:

a := [10]int{1, 2}
fmt.Printf("a: %v\n", a)

x, y := a[:2:2], []int{3, 4}
fmt.Printf("x: %v, y: %v\n", x, y)
fmt.Printf("cap(x): %v\n", cap(x))

x = append(x, y...)
fmt.Printf("x: %v\n", x)

fmt.Printf("a: %v\n", a)

Output (try it on the Go Playground)

a: [1 2 0 0 0 0 0 0 0 0]
x: [1 2], y: [3 4]
cap(x): 2
x: [1 2 3 4]
a: [1 2 0 0 0 0 0 0 0 0]

As you can see, we get the same x result but the backing array a did not change, because capacity of x was "only" 2 (thanks to the full slice expression a[:2:2]). So to do the append, a new backing array is allocated that can store the elements of both x and y, which is distinct from a.

If you have arrived here via google, please make sure to check that you have given self as the first parameter to a class function. Especially if you try to reference values for that object instance inside the class function.

def foo():
    print(self.bar)

>NameError: name 'self' is not defined

def foo(self):
    print(self.bar)

if (User.Identity.IsAuthenticated)
{
    Page.Title = "Home page for " + User.Identity.Name;
}
else
{
    Page.Title = "Home page for guest user.";
}

Reloading existing classes with existing data is likely to break things.

You can load new code into new class loaders relatively easily:

ClassLoader loader = URLClassLoader.newInstance(
    new URL[] { yourURL },
    getClass().getClassLoader()
);
Class<?> clazz = Class.forName("mypackage.MyClass", true, loader);
Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class);
// Avoid Class.newInstance, for it is evil.
Constructor<? extends Runnable> ctor = runClass.getConstructor();
Runnable doRun = ctor.newInstance();
doRun.run();

Class loaders no longer used can be garbage collected (unless there is a memory leak, as is often the case with using ThreadLocal, JDBC drivers, java.beans, etc).

If you want to keep the object data, then I suggest a persistence mechanism such as Serialisation, or whatever you are used to.

Of course debugging systems can do fancier things, but are more hacky and less reliable.

It is possible to add new classes into a class loader. For instance, using URLClassLoader.addURL. However, if a class fails to load (because, say, you haven't added it), then it will never load in that class loader instance.

If you want a pure CSS solution, this trick works very well - use the transform object. This also works with images when they're cached or not:

CSS:

.main_container{
    position: relative;
    width: 500px;
    height: 300px;
    background-color: #cccccc;
}

.center_horizontally{
  position: absolute;
  width: 100px;
  height: 100px;
  background-color: green;
  left: 50%;
  top: 0;
  transform: translate(-50%,0);
}

.center_vertically{
  position: absolute;
  top: 50%;
  left: 0;
  width: 100px;
  height: 100px;
  background-color: blue;
  transform: translate(0,-50%);
}

.center{
  position: absolute;
  top: 50%;
  left: 50%;
  width: 100px;
  height: 100px;
  background-color: red;
  transform: translate(-50%,-50%);
}

HTML:

<div class="main_container">
  <div class="center_horizontally"></div>
  <div class="center_vertically"></div>
  <div class="center"></div>
  </div>
</div

You almost never want to use Read Uncommited since it's not really ACID compliant. Read Commmited is a good default starting place. Repeatable Read is probably only needed in reporting, rollup or aggregation scenarios. Note that many DBs, postgres included don't actually support Repeatable Read, you have to use Serializable instead. Serializable is useful for things that you know have to happen completely independently of anything else; think of it like synchronized in Java. Serializable goes hand in hand with REQUIRES_NEW propagation.

I use REQUIRES for all functions that run UPDATE or DELETE queries as well as "service" level functions. For DAO level functions that only run SELECTs, I use SUPPORTS which will participate in a TX if one is already started (i.e. being called from a service function).

If you made it here it is possible that you had the same problem i did. My issue was that i was defining another model with the same name. I called my gallery and my file model "File". Darn you copy and paste!

Use vars()

class Foo(object):
    def __init__(self):
        self.a = 1
        self.b = 2

vars(Foo()) #==> {'a': 1, 'b': 2}
vars(Foo()).keys() #==> ['a', 'b']

CGRect screenBounds = [[UIScreen mainScreen] bounds];

That will give you the entire screen's resolution in points, so it would most typically be 320x480 for iPhones. Even though the iPhone4 has a much larger screen size iOS still gives back 320x480 instead of 640x960. This is mostly because of older applications breaking.

CGFloat screenScale = [[UIScreen mainScreen] scale];

This will give you the scale of the screen. For all devices that do not have Retina Displays this will return a 1.0f, while Retina Display devices will give a 2.0f and the iPhone 6 Plus (Retina HD) will give a 3.0f.

Now if you want to get the pixel width & height of the iOS device screen you just need to do one simple thing.

CGSize screenSize = CGSizeMake(screenBounds.size.width * screenScale, screenBounds.size.height * screenScale);

By multiplying by the screen's scale you get the actual pixel resolution.

A good read on the difference between points and pixels in iOS can be read here.

EDIT: (Version for Swift)

let screenBounds = UIScreen.main.bounds
let screenScale = UIScreen.main.scale
let screenSize = CGSize(width: screenBounds.size.width * screenScale, height: screenBounds.size.height * screenScale)

In Swift you can do like this

let number : NSNumber = 95
let str : String = number.stringValue

If you want to declare date and then use it in SQL Developer.

DEFINE PROPp_START_DT = TO_DATE('01-SEP-1999')

-v is the "inverted match" flag, so piping is a very good way:

              k=(((i.split("\n"))[0].rstrip()).split() for i in f.readlines())
              d={}
              for i,_,v in k:
                      d.setdefault(i,[]).append(v)

you could use

$('.buttons').on('click', 'button', function(){
    // your magic goes here
});

or

$('.buttons').delegate('button', 'click', function() {
    // your magic goes here
});

these two methods are equivalent but have a different order of parameters.

The fastest way I found was, using while:

mysetup = '''
import numpy as np
from find_intervals import return_intersections 
'''

# code snippet whose execution time is to be measured
mycode = '''

x = [4,5,6,7,8,9,10]
prod = 1
i = 0
while True:
    prod = prod * x[i]
    i = i + 1
    if i == len(x):
        break
'''

# timeit statement for while:
print("using while : ",
timeit.timeit(setup=mysetup,
              stmt=mycode))

# timeit statement for mul:
print("using mul : ",
    timeit.timeit('from functools import reduce;
    from operator import mul;
    c = reduce(mul, [4,5,6,7,8,9,10])'))

# timeit statement for mul:
print("using lambda : ",      
    timeit.timeit('from functools import reduce;
    from operator import mul;
    c = reduce(lambda x, y: x * y, [4,5,6,7,8,9,10])'))

and the timings are:

>>> using while : 0.8887967770060641

>>> using mul : 2.0838719510065857

>>> using lambda : 2.4227715369997895

Do it like this. This approach lets you search a file of any size (big size won't crash the script) and will return ALL lines that match the string you want.

<?php
$searchthis = "mystring";
$matches = array();

$handle = @fopen("path/to/inputfile.txt", "r");
if ($handle)
{
    while (!feof($handle))
    {
        $buffer = fgets($handle);
        if(strpos($buffer, $searchthis) !== FALSE)
            $matches[] = $buffer;
    }
    fclose($handle);
}

//show results:
print_r($matches);
?>

Note the way strpos is used with !== operator.

What about this?

No need of JQuery simply you can do

if(yourObject['email']){
 // what if this property exists.
}

as with any value for email will return you true, if there is no such property or that property value is null or undefined will result to false

I use gkill processname, where gkill is the following script:

cnt=`ps aux|grep $1| grep -v "grep" -c`
if [ "$cnt" -gt 0 ]
then
    echo "Found $cnt processes - killing them"
    ps aux|grep $1| grep -v "grep"| awk '{print $2}'| xargs kill
else
    echo "No processes found"
fi

NOTE: it will NOT kill processes that have "grep" in their command lines.

Try VIM

If you have vim you can use this:

Not tested for every encoding.

The cool part about this is that you don't have to know the source encoding

vim +"set nobomb | set fenc=utf8 | x" filename.txt

Be aware that this command modify directly the file

Explanation part!

1. + : Used by vim to directly enter command when opening a file. Usualy used to open a file at a specific line: vim +14 file.txt
2. | : Separator of multiple commands (like ; in bash)
3. set nobomb : no utf-8 BOM
4. set fenc=utf8 : Set new encoding to utf-8 doc link
5. x : Save and close file
6. filename.txt : path to the file
7. " : qotes are here because of pipes. (otherwise bash will use them as bash pipe)

I woudn't bother with the likelihood of collision. Just generate a random string and check if it exists. If it does, try again and you shouldn't need to do it more that a couple of times unless you have a huge number of plates already assigned.

Another solution for generating an 8-character long pseudo-random string in pure (My)SQL:

SELECT LEFT(UUID(), 8);

You can try the following (pseudo-code):

DO 
    SELECT LEFT(UUID(), 8) INTO @plate;
    INSERT INTO plates (@plate);
WHILE there_is_a_unique_constraint_violation
-- @plate is your newly assigned plate number

Since this post has received a unexpected level of attention, let me highlight ADTC's comment : the above piece of code is quite dumb and produces sequential digits.

For slightly less stupid randomness try something like this instead :

SELECT LEFT(MD5(RAND()), 8)

And for true (cryptograpically secure) randomness, use RANDOM_BYTES() rather than RAND() (but then I would consider moving this logic up to the application layer).

Use regex pattern ^(?=.{8})(?=.*[^a-zA-Z])

Explanation:

^(?=.{8})(?=.*[^a-zA-Z])
¦+------++-------------+
¦   ¦           ¦
¦   ¦           + string contains some non-letter character
¦   ¦
¦   + string contains at least 8 characters
¦
+ begining of line/string

If you want to limit also maximum length (let's say 16), then use regex pattern:

^(?=.{8,16}$)(?=.*[^a-zA-Z])

I was having the same trouble and I did

pip install pygame

and that worked for me!

If you want to convert back the file formats which have been changed to UNIX Format from PC format.

(1)You need to reinstall tortoise GIT and in the "Line Ending Conversion" Section make sure that you have selected "Check out as is - Check in as is"option.

(2)and keep the remaining configurations as it is.

(3)once installation is done

(4)write all the file extensions which are converted to UNIX format into a text file (extensions.txt).

ex:*.dsp
   *.dsw

(5) copy the file into your clone Run the following command in GITBASH

while read -r a;
do
find . -type f -name "$a" -exec dos2unix {} \;
done<extension.txt

Look into using the --null commandline option for xargs with the -print0 option in find.

change type="number" to type="tel"

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

Not exactly the most robust password protection here, so please don't use this to protect credit card numbers or something very important.

Simply drop all of the following code into a file called (secure.php), change the user and pass from "admin" to whatever you want. Then right under those lines where it says include("secure.html"), simply replace that with the filename you want them to be able to see.

They will access this page at [YouDomain.com/secure.php] and then the PHP script will internally include the file you want password protected so they won't know the name of that file, and can't later just access it directly bypassing the password prompt.

If you would like to add a further level of protection, I would recommend you take your (secure.html) file outside of your site's root folder [/public_html], and place it on the same level as that directory, so that it is not inside the directory. Then in the PHP script where you are including the file simply use ("../secure.html"). That (../) means go back a directory to find the file. Doing it this way, the only way someone can access the content that's on the (secure.html) page is through the (secure.php) script.

<?php
$user = $_POST['user'];
$pass = $_POST['pass'];

if($user == "admin"
&& $pass == "admin")
{
        include("secure.html");
}
else
{
    if(isset($_POST))
    {?>

            <form method="POST" action="secure.php">
            User <input type="text" name="user"></input><br/>
            Pass <input type="password" name="pass"></input><br/>
            <input type="submit" name="submit" value="Go"></input>
            </form>
    <?}
}
?>

Have a look at jQuery's .parseXML() ^[docs]:

var $xml = $(jQuery.parseXML(xml));

var $test = $xml.find('Page[Name="test"] > controls > test');

 // Define appendVal by extending JQuery_x000D_
 $.fn.appendVal = function( TextToAppend ) {_x000D_
  return $(this).val(_x000D_
   $(this).val() + TextToAppend_x000D_
  );_x000D_
 };_x000D_
//______________________________________________x000D_
_x000D_
 // And that's how to use it:_x000D_
 $('#SomeID')_x000D_
  .appendVal( 'This text was just added' )

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form>_x000D_
<textarea _x000D_
          id    =  "SomeID"_x000D_
          value =  "ValueText"_x000D_
          type  =  "text"_x000D_
>Current NodeText_x000D_
</textarea>_x000D_
  </form>

Well when creating this example I somehow got a little confused. "ValueText" vs >Current NodeText< Isn't .val() supposed to run on the data of the value attribute? Anyway I and you me may clear up this sooner or later.

However the point for now is:

When working with form data use .val().

When dealing with the mostly read only data in between the tag use .text() or .append() to append text.

yes, Scrapy can scrap dynamic websites, website that are rendered through javaScript.

There are Two approaches to scrapy these kind of websites.

First,

you can use splash to render Javascript code and then parse the rendered HTML. you can find the doc and project here Scrapy splash, git

Second,

As everyone is stating, by monitoring the network calls, yes, you can find the api call that fetch the data and mock that call in your scrapy spider might help you to get desired data.

I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange="" attribute to the input tag:

<input type='file' onchange='getFilename(this)'/>

function getFileName(elm) {
   var fn = $(elm).val();
   ....
}

EDIT:

function getFileName(elm) {
   var fn = $(elm).val();
   var filename = fn.match(/[^\\/]*$/)[0]; // remove C:\fakename
   alert(filename);
}

Also another obscure possibility:

$oldDate = '2010-03-20'
$arr = explode('-', $oldDate);
$newDate = $arr[2].'-'.$arr[1].'-'.$arr[0];

I don't know if I would use it but still :)

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

The margin of the elements contained within .child are collapsing.

<html>
<style type="text/css" media="screen">
    #parent {background:#dadada;}
    #child {background:red; margin-top:17px;}
</style>
<body>
<div id="parent">

    <p>&amp;</p>

    <div id="child">
        <p>&amp;</p>    
    </div>

</div>
</body>
</html>

In this example, p is receiving a margin from the browser default styles. Browser default font-size is typically 16px. By having a margin-top of more than 16px on #child you start to notice it's position move.

If you are working with ASP.NET MVC, you can solve the problem by adding the MaxJsonLength to your result:

var jsonResult = Json(new
{
    draw = param.Draw,
    recordsTotal = count,
    recordsFiltered = count,
    data = result
}, JsonRequestBehavior.AllowGet);
jsonResult.MaxJsonLength = int.MaxValue;

When we get some error from our application, Logcat will show session filter automatically. We can create session filter by self. Just add a new logcat filter, fill the filter name form. Then fill the by application name with your application package. (for example : my application is "Adukan" and the package is "com.adukan", so I fill by application name with application package "com.adukan")

Don't forget to restart your XAMPP Server

Update the accepted answer :

now you need to comment Require local

Consider both at the same time:

• having singleton objects as static instances inside the classes.
• having a common class (Context) that returns the singleton instances for all the singelton objects in your application, which has the advantage that the method names in Context will be meaningful for example: context.getLoggedinUser() instead of User.getInstance().

Furthermore, I suggest that you expand your Context to include not only access to singleton objects but some functionalities that need to be accessed globally, like for example: context.logOffUser(), context.readSavedData(), etc. Probably renaming the Context to Facade would make sense then.

Sometimes you have to remove the current options in order to manipulate the selected options.

Here is an example how to set options:

<select id="mySelectId" class="chosen-select" multiple="multiple">
  <option value=""></option>
  <option value="Argentina">Argentina</option>
  <option value="Germany">Germany</option>
  <option value="Greece">Greece</option>
  <option value="Japan">Japan</option>
  <option value="Thailand">Thailand</option>
</select>

<script>
activateChosen($('body'));
selectChosenOptions($('#mySelectId'), ['Argentina', 'Germany']);

function activateChosen($container, param) {
    param = param || {};
    $container.find('.chosen-select:visible').chosen(param);
    $container.find('.chosen-select').trigger("chosen:updated");
}

function selectChosenOptions($select, values) {
    $select.val(null);                                  //delete current options
    $select.val(values);                                //add new options
    $select.trigger('chosen:updated');
}
</script>

Applying the BoxCox transformation to data, without the need of any underlying model, can be done currently using the package geoR. Specifically, you can use the function boxcoxfit() for finding the best parameter and then predict the transformed variables using the function BCtransform().

To make this work work with all browsers including Chrome you need to make the callback function of sort() return -1,0 or 1.

see http://inderpreetsingh.com/2010/12/01/chromes-javascript-sort-array-function-is-different-yet-proper/

function sortUL(selector) {
    $(selector).children("li").sort(function(a, b) {
        var upA = $(a).text().toUpperCase();
        var upB = $(b).text().toUpperCase();
        return (upA < upB) ? -1 : (upA > upB) ? 1 : 0;
    }).appendTo(selector);
}
sortUL("ul.mylist");

You can use argv npm module (install it by running npm install argv --save) for getting params in your webpack.config.js file and as for production you use -p flag "build": "webpack -p", you can add condition in webpack.config.js file like below

plugins: [
    new webpack.DefinePlugin({
        'process.env':{
            'NODE_ENV': argv.p ? JSON.stringify('production') : JSON.stringify('development')
        }
    })
]

And thats it.

Program Debug Database file (pdb) is a file format by Microsoft for storing debugging information.

When you build a project using Visual Studio or command prompt the compiler creates these symbol files.

Check Microsoft Docs

when you create empty array values ARE NOT undefined, they are EMPTY

var arr = new Array(10); // (10) [empty × 10]

but when you get item by index receive undefined

arr[0]; // undefined

so you can't know by === comparing if they are undefined or empty

we can make it by using JSON.stringify, converting whole array it replaces empty values with null

JSON.stringify(arr); // "[null,null,null,null,null,null,null,null,null,null]"
JSON.stringify(arr[0]); // but for single item it returns undefined

so real check for empty value:

arr[0] !== null && JSON.stringify(arr.map(item => !item)).slice(1, -1).split(',')[0] === 'null'

1. compare item with null (should be not equal)
2. map array removing false instead existing values (ensure stringified structure to be comma-separated without redundant commas)
3. JSON.stringify array
4. remove brackets from string
5. split into array by comma
6. compare with null

Not only can it, it always does. If you do not specify one then it has a default no arg constructor, just like any other class. In fact, ALL classes, including nested and anonymous classes, will get a default constructor if one is not specified (in the case of anonymous classes it is impossible to specify one, so you will always get the default constructor).

A good example of an abstract class having a constructor is the Calendar class. You get a Calendar object by calling Calendar.getInstance(), but it also has constructors which are protected. The reason its constructors are protected is so that only its subclasses can call them (or classes in the same package, but since it's abstract, that doesn't apply). GregorianCalendar is an example of a class that extends Calendar.

There are 8 bits in a byte (normally speaking in Windows).

However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.

In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.

EDITED

Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.

if you want to pass POST variables, you have to use a HTML Form:

<form action="http://localhost:8080/login" method="POST" target="_blank">
    <input type="text" name="cid" />
    <input type="password" name="pwd" />
    <input type="submit" value="open" />
</form>

or:

if you want to pass GET variables in an URL, write them without single-quotes:

http://yourdomain.com/login?cid=username&pwd=password

here's how to create the string above with javascrpt variables:

myu = document.getElementById('cid').value;
myp = document.getElementById('pwd').value;
window.open("http://localhost:8080/login?cid="+ myu +"&pwd="+ myp ,"MyTargetWindowName");

in the document with that url, you have to read the GET parameters. if it's in php, use:

$_GET['username']

be aware: to transmit passwords that way is a big security leak!

Since y is an iterable I really do not see why the calls to append:

a = np.array(list(y))

will do and it's much faster:

import timeit

print timeit.timeit('list(s)', 's=set(x for x in xrange(1000))')
# 23.952975494633154

print timeit.timeit("""li=[]
for x in s: li.append(x)""", 's=set(x for x in xrange(1000))')
# 189.3826994248866

you can try in this way if you are using thymeleaf

sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
               T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"

this will return true if the user has the mentioned roles,false otherwise.

Please note you have to use sec tag in your html declaration tag like this

<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

I had the same issue, and by Running "exec sp_updatestats" the issue solved and works now

You don't mention if this is a GUI program or not, but most GUI packages include a way to capture and handle keyboard input. For example, with tkinter (in Py3), you can bind to a certain event and then handle it in a function. For example:

import tkinter as tk

def key_handler(event=None):
    if event and event.keysym in ('s', 'p'):
        'do something'

r = tk.Tk()
t = tk.Text()
t.pack()
r.bind('<Key>', key_handler)
r.mainloop()

With the above, when you type into the Text widget, the key_handler routine gets called for each (or almost each) key you press.

I only use the forward slash once at the end of each script, to tell sqlplus that there is not more lines of code. In the middle of a script, I do not use a slash.

Another thing to remember is that request.POST['keyword'] refers to the element identified by the specified html name attribute keyword.

So, if your form is:

<form action="/login/" method="POST">
  <input type="text" name="keyword" placeholder="Search query">
  <input type="number" name="results" placeholder="Number of results">
</form>

then, request.POST['keyword'] and request.POST['results'] will contain the value of the input elements keyword and results, respectively.

If you are getting this problem when converting wsdl to jave with the cxf-codegen-plugin, then you can solve it by configuring the plugin to fork and provide the additional "-Djavax.xml.accessExternalSchema=all" JVM option.

        <plugin>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-codegen-plugin</artifactId>
            <version>${cxf.version}</version>
            <executions>
                <execution>
                    <id>generate-sources</id>
                    <phase>generate-sources</phase>
                    <configuration>
                        <fork>always</fork>
                        <additionalJvmArgs>
                            -Djavax.xml.accessExternalSchema=all
                        </additionalJvmArgs>

try:
    return a[0]
except IndexError:
    return None

Here is one of the most efficient way, it works smoothly:

https://github.com/MikeOrtiz/TouchImageView

Place TouchImageView.java in your project. It can then be used the same as ImageView.

Example:

TouchImageView img = (TouchImageView) findViewById(R.id.img);

If you are using TouchImageView in xml, then you must provide the full package name, because it is a custom view.

Example:

    <com.example.touch.TouchImageView
            android:id="@+id/img”
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

((frmMain)this.Owner).MyListControl.Items.Add("abc");

Make sure to provide access level you want at Modifiers properties other than Private for MyListControl at frmMain

You can't call methods outside a method. Code like this cannot float around in the class.

You need something like:

public class MyClass {

  UserInput input = new UserInput();

  public void foo() {
      input.name();
  }
}

or inside a constructor:

public class MyClass {

  UserInput input = new UserInput();

  public MyClass() {
      input.name();
  }
}

Modify your filter like this:

filter isNumeric {
    [Helpers]::IsNumeric($_)
}

function uses the $input variable to contain pipeline information whereas the filter uses the special variable $_ that contains the current pipeline object.

Edit:

For a powershell syntax way you can use just a filter (w/o add-type):

filter isNumeric() {
    return $_ -is [byte]  -or $_ -is [int16]  -or $_ -is [int32]  -or $_ -is [int64]  `
       -or $_ -is [sbyte] -or $_ -is [uint16] -or $_ -is [uint32] -or $_ -is [uint64] `
       -or $_ -is [float] -or $_ -is [double] -or $_ -is [decimal]
}

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.

My solution - solved it for Angular 5 with Material View
The connection is through the

formArrayName="notification"

(change)="updateChkbxArray(n.id, $event.checked, 'notification')"

This way it can work for multiple checkboxes arrays in one form. Just set the name of the controls array to connect each time.

constructor(_x000D_
  private fb: FormBuilder,_x000D_
  private http: Http,_x000D_
  private codeTableService: CodeTablesService) {_x000D_
_x000D_
  this.codeTableService.getnotifications().subscribe(response => {_x000D_
      this.notifications = response;_x000D_
    })_x000D_
    ..._x000D_
}_x000D_
_x000D_
_x000D_
createForm() {_x000D_
  this.form = this.fb.group({_x000D_
    notification: this.fb.array([])..._x000D_
  });_x000D_
}_x000D_
_x000D_
ngOnInit() {_x000D_
  this.createForm();_x000D_
}_x000D_
_x000D_
updateChkbxArray(id, isChecked, key) {_x000D_
  const chkArray = < FormArray > this.form.get(key);_x000D_
  if (isChecked) {_x000D_
    chkArray.push(new FormControl(id));_x000D_
  } else {_x000D_
    let idx = chkArray.controls.findIndex(x => x.value == id);_x000D_
    chkArray.removeAt(idx);_x000D_
  }_x000D_
}

<div class="col-md-12">_x000D_
  <section class="checkbox-section text-center" *ngIf="notifications  && notifications.length > 0">_x000D_
    <label class="example-margin">Notifications to send:</label>_x000D_
    <p *ngFor="let n of notifications; let i = index" formArrayName="notification">_x000D_
      <mat-checkbox class="checkbox-margin" (change)="updateChkbxArray(n.id, $event.checked, 'notification')" value="n.id">{{n.description}}</mat-checkbox>_x000D_
    </p>_x000D_
  </section>_x000D_
</div>

At the end you are getting to save the form with array of original records id's to save/update.

Will be happy to have any remarks for improvement.

Get process explorer from sysinternals (now Microsoft)

Process Explorer - Windows Sysinternals | Microsoft Docs

You should be denoting the call by reference in the function definition, not the actual call. Since PHP started showing the deprecation errors in version 5.3, I would say it would be a good idea to rewrite the code.

From the documentation:

There is no reference sign on a function call - only on function definitions. Function definitions alone are enough to correctly pass the argument by reference. As of PHP 5.3.0, you will get a warning saying that "call-time pass-by-reference" is deprecated when you use & in foo(&$a);.

For example, instead of using:

// Wrong way!
myFunc(&$arg);               # Deprecated pass-by-reference argument
function myFunc($arg) { }

Use:

// Right way!
myFunc($var);                # pass-by-value argument
function myFunc(&$arg) { }

Nothing printed. The argument must be a pointer to a signed int, where the number of characters written so far is stored.

#include <stdio.h>

int main()
{
  int val;

  printf("blah %n blah\n", &val);

  printf("val = %d\n", val);

  return 0;

}

The previous code prints:

blah  blah
val = 5

I bet this is what was intended as a result.

Simple to Spit String by Space

    String CurrentString = "First Second Last";
    String[] separated = CurrentString.split(" ");

    for (int i = 0; i < separated.length; i++) {

             Log.d("FName ** ", "" + separated[0].trim() + "\n ");
         } else if (i == 1) {
             Log.d("MName ** ", "" + separated[1].trim() + "\n ");
         } else if (i == 2) {

Installing CuDNN just involves placing the files in the CUDA directory. If you have specified the routes and the CuDNN option correctly while installing caffe it will be compiled with CuDNN.

You can check that using cmake. Create a directory caffe/build and run cmake .. from there. If the configuration is correct you will see these lines:

-- Found cuDNN (include: /usr/local/cuda-7.0/include, library: /usr/local/cuda-7.0/lib64/libcudnn.so)

-- NVIDIA CUDA:
--   Target GPU(s)     :   Auto
--   GPU arch(s)       :   sm_30
--   cuDNN             :   Yes

If everything is correct just run the make orders to install caffe from there.

Prefixing the statement with an exclamation mark will let you know whether the array is not empty. So in your case -

a = [1,2,3]
!a.empty?
=> true

This helps me, https://pip.pypa.io/en/stable/installing/

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

If you are using python3 and not set it default. do this,

python3 get-pip.py

It works for me.

teach your editor to do it-

after writing "pr_" tab i get exactly

print("<pre>");
print_r($);
print("</pre>");

with the cursor just after the $

i did it on textmate by adding this snippet:

print("<pre>");
print_r(\$${1:});
print("</pre>");

Check you class name first. It should be p1 as per your batch file instruction. And then check you package of that class, if it is inside any package, specify when you run.

If package is x.y

java x.y.p1

I solved this by renaming the branch in the file .git/refs/remotes/origin/HEAD.

Why not just

$q->where("a = 1");
$q->andWhere("b = 1 OR b = 2");
$q->andWhere("c = 1 OR d = 2");

EDIT: You can also use the Expr class (Doctrine2).

I am not very familiar with CMake and could not use Mondkin's solution directly.

Here is what I came up with in my CMakeLists.txt using the latest version of CLion (1.2.4) and MinGW on Windows (I guess you will just need to replace all: g++ mytest.cpp -o bin/mytest by make if you are not using the same setup):

cmake_minimum_required(VERSION 3.3)
project(mytest)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

add_custom_target(mytest ALL COMMAND mingw32-make WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR})

And the custom Makefile is like this (it is located at the root of my project and generates the executable in a bin directory):

all:
    g++ mytest.cpp -o bin/mytest

I am able to build the executable and errors in the log window are clickable.

Hints in the IDE are quite limited through, which is a big limitation compared to pure CMake projects...

On Ubuntu I went to

~/.eclipse/org.eclipse.platform_4.3.0_1473617060_linux_gtk_x86_64/configuration/config.ini

I combined @Frank answer with @Ronan Quillevere's comment

I had this problem as well on an OSX machine. I discovered that rails was not installed... which surprised me as I thought OSX always came with Rails. To install rails

• sudo gem install rails
• to install jekyll I also needed sudo
• sudo gem install jekyll bundler
• cd ~/Sites
• jekyll new <foldername>
• cd <foldername> OR cd !$ (that is magic ;)
• bundle install
• bundle exec jekyll serve
• Then in your browser just go to http://127.0.0.1:4000/ and it really should be running

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

Some extensions like blocksite use the accessibility service API to deploy extension like features to Chrome on Android. Might be worth a look through the play store. Otherwise, Firefox is your best bet, though many extensions don't work on mobile for some reason.

You're looking for the --data-binary argument:

curl -i -X POST host:port/post-file \
  -H "Content-Type: text/xml" \
  --data-binary "@path/to/file"

In the example above, -i prints out all the headers so that you can see what's going on, and -X POST makes it explicit that this is a post. Both of these can be safely omitted without changing the behaviour on the wire. The path to the file needs to be preceded by an @ symbol, so curl knows to read from a file.

You can use the rotate attribute

 <item>
    <rotate
        android:fromDegrees="90"
        android:toDegrees="90"
        android:pivotX="50%"
        android:pivotY="50%" >
        <shape
            android:shape="line"
            android:top="1dip" >
            <stroke
                android:width="1dip"
                 />
        </shape>
    </rotate>
</item>

Just try to add exit; at the end of your PHP script.

So I discovered that in your ~/.zshrc file, there was a commented line,

# If you come from bash you might have to change your $PATH # export PATH=$HOME/bin:/usr/local/bin:$PATH

Just uncomment the export statement and all your previous bash_profile commands will also be there. If that comment does not exist, you can also just add that export statement to .zshrc file.

Adding to Dmitri Chebotarev's answer, as for Laravel 5+.

After requiring the doctrine/dbal package:

composer require doctrine/dbal

You can then make a migration with nullable columns, like so:

public function up()
{
    Schema::table('users', function (Blueprint $table) {
        // change() tells the Schema builder that we are altering a table
        $table->integer('user_id')->unsigned()->nullable()->change();
    });
}

To revert the operation, do:

public function down()
{
    /* turn off foreign key checks for a moment */
    DB::statement('SET FOREIGN_KEY_CHECKS = 0');
    /* set null values to 0 first */
    DB::statement('UPDATE `users` SET `user_id` = 0 WHERE `user_id` IS NULL;');
    /* alter table */
    DB::statement('ALTER TABLE `users` MODIFY `user_id` INTEGER UNSIGNED NOT NULL;');
    /* finally turn foreign key checks back on */
    DB::statement('SET FOREIGN_KEY_CHECKS = 1');
}

Here is an example of concatenation operator:

architecture EXAMPLE of CONCATENATION is
   signal Z_BUS : bit_vector (3 downto 0);
   signal A_BIT, B_BIT, C_BIT, D_BIT : bit;
begin
   Z_BUS <= A_BIT & B_BIT & C_BIT & D_BIT;
end EXAMPLE;

Including Points:

1. SSL setup
   1. In config/local.js
   2. In config/env/production.js

HTTP and WS handling

1. The app must run on HTTP in development so we can easily debug our app.
2. The app must run on HTTPS in production for security concern.
3. App production HTTP request should always redirect to https.

SSL configuration

In Sailsjs there are two ways to configure all the stuff, first is to configure in config folder with each one has their separate files (like database connection regarding settings lies within connections.js ). And second is configure on environment base file structure, each environment files presents in config/env folder and each file contains settings for particular env.

Sails first looks in config/env folder and then look forward to config/ *.js

Now lets setup ssl in config/local.js.

var local = {
   port: process.env.PORT || 1337,
   environment: process.env.NODE_ENV || 'development'
};

if (process.env.NODE_ENV == 'production') {
    local.ssl = {
        secureProtocol: 'SSLv23_method',
        secureOptions: require('constants').SSL_OP_NO_SSLv3,
        ca: require('fs').readFileSync(__dirname + '/path/to/ca.crt','ascii'),
        key: require('fs').readFileSync(__dirname + '/path/to/jsbot.key','ascii'),
        cert: require('fs').readFileSync(__dirname + '/path/to/jsbot.crt','ascii')
    };
    local.port = 443; // This port should be different than your default port
}

module.exports = local;

Alternative you can add this in config/env/production.js too. (This snippet also show how to handle multiple CARoot certi)

Or in production.js

module.exports = {
    port: 443,
    ssl: {
        secureProtocol: 'SSLv23_method',
        secureOptions: require('constants').SSL_OP_NO_SSLv3,
        ca: [
            require('fs').readFileSync(__dirname + '/path/to/AddTrustExternalCARoot.crt', 'ascii'),
            require('fs').readFileSync(__dirname + '/path/to/COMODORSAAddTrustCA.crt', 'ascii'),
            require('fs').readFileSync(__dirname + '/path/to/COMODORSADomainValidationSecureServerCA.crt', 'ascii')
        ],
        key: require('fs').readFileSync(__dirname + '/path/to/jsbot.key', 'ascii'),
        cert: require('fs').readFileSync(__dirname + '/path/to/jsbot.crt', 'ascii')
    }
};

http/https & ws/wss redirection

Here ws is Web Socket and wss represent Secure Web Socket, as we set up ssl then now http and ws both requests become secure and transform to https and wss respectively.

There are many source from our app will receive request like any blog post, social media post but our server runs only on https so when any request come from http it gives “This site can’t be reached” error in client browser. And we loss our website traffic. So we must redirect http request to https, same rules allow for websocket otherwise socket will fails.

So we need to run same server on port 80 (http), and divert all request to port 443(https). Sails first compile config/bootstrap.js file before lifting server. Here we can start our express server on port 80.

In config/bootstrap.js (Create http server and redirect all request to https)

module.exports.bootstrap = function(cb) {
    var express = require("express"),
        app = express();

    app.get('*', function(req, res) {  
        if (req.isSocket) 
            return res.redirect('wss://' + req.headers.host + req.url)  

        return res.redirect('https://' + req.headers.host + req.url)  
    }).listen(80);
    cb();
};

Now you can visit http://www.yourdomain.com, it will redirect to https://www.yourdomain.com

For this error was like others said a big image(1800px X 900px) which was in drawable directory, I edited the image and reduced the size proportionally using photoshop and it worked...!!

Which version of .NET are you using? If it's .NET 3.5, I'd just call ToArray() and be done with it.

If you only have a non-generic IEnumerable, do something like this:

IEnumerable query = ...;
MyEntityType[] array = query.Cast<MyEntityType>().ToArray();

If you don't know the type within that method but the method's callers do know it, make the method generic and try this:

public static void T[] PerformQuery<T>()
{
    IEnumerable query = ...;
    T[] array = query.Cast<T>().ToArray();
    return array;
}

For multiple times of execution of our model, random state make sure that data values will be same for training and testing data sets. It fixes the order of data for train_test_split

Simple !!... you can do it easily via server.xml

• Go to tomcat>conf folder
• Edit server.xml
• Search "Connector port"
• Replace "8080" by your port number
• Restart tomcat server.

You are done!.

Open Notepad++
Select Replace (Ctrl/H)

One approach would be to write a simple Java Web Service (REST/JSON) that uses JODA library

http://joda-time.sourceforge.net/faq.html#datediff

to calculate difference between two dates and call that service from javascript.

This assumes your back end is in Java.

Take a pointer to the first element instead:

process_data (&something [0]);

The command is lowercase: touch filename.

Keep in mind that touch will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch

If you always want an empty file, one way to do so would be to use:

echo "" > filename

mysqli_error() needs you to pass the connection to the database as a parameter. Documentation here has some helpful examples:

http://php.net/manual/en/mysqli.error.php

Try altering your problem line like so and you should be in good shape:

$query = mysqli_query($myConnection, $sqlCommand) or die (mysqli_error($myConnection)); 

Percent encoding. Replace the hash with %23.

For Oracle, please use this simple command:

ALTER SESSION SET current_schema = your-schema-without-quotes;

change ;memory_limit=512M to ;memory_limit=-1 in

it's too dangerous for a server Your PHP code may have a memory leak somewhere and you are telling the server to just use all the memory that it wants. You wouldn't have fixed the problem at all. If you monitor your server, you will see that it is now probably using up most of the RAM and even swapping to disk.

I used the below dependency. If you are using Selenium then it's good to use all of them as below. Else you will see some errors and then do the reserch and add some more dependencies.

Actually you have 2 problems here: First is that you don't have ssh installed, second is that you don't know how to deploy

Install SSH

It seems that ssh is not installed on your computer.

You can install openssh from here : http://openssh.en.softonic.com/download

Generate your key

Than you will have to geneate your ssh-key. There's a good tutorial about this here:

https://help.github.com/articles/generating-ssh-keys#platform-windows

Deploy

To deploy, you just have to push your code over git. Something like this:

git push fort master

If you get permission denied, be sure that you have put your public_key in the dashboard in the git tab.

SSH

The ssh command gives you access to your remote node. You should have received a password by email and now that you have ssh installed, you should be asked for a password when trying to connect. just input that password. If you want to use your private ssh key to connect to your server rather then typing that password, you can follow this : http://fortrabbit.com/docs/how-to/ssh-sftp/enable-public-key-authentication

There is also the possibility to use the Vector Asset Studio in combination with Scalable Vector Graphics (SVG). Android Studio will handle the rest for you. As the official documentation says:

Vector Asset Studio helps you add material icons and import Scalable Vector Graphic (SVG) files into your app project as a drawable resource. Compared to raster images, vector drawables can reduce the size of your app and be resized without loss of image quality. They help you to more easily support different Android devices with varying screen sizes and resolutions because you can display one vector drawable on all of them.

I consider this the future approach.

When i copied the date format for timestamp and used that for date, it did not work. But changing the date format to this (DD-MON-YY HH12:MI:SS AM) worked for me.

The change has to be made in Tools->Preferences-> search for NLS

Improvement of Alejandro's answer. You can leave the $start or $end arguments empty and it will use the start or end of the string.

echo get_string_between("Hello my name is bob", "my", ""); //output: " name is bob"

private function get_string_between($string, $start, $end){ // Get
    if($start != ''){ //If $start is empty, use start of the string
        $string = ' ' . $string;
        $ini = strpos($string, $start);
        if ($ini == 0) return '';
        $ini += strlen($start);
    }
    else{
        $ini = 0;
    }

    if ($end == '') { //If $end is blank, use end of string
        return substr($string, $ini);
    }
    else{
        $len = strpos($string, $end, $ini) - $ini; //Work out length of string
        return substr($string, $ini, $len);
    }
}

use this

from collections import Counter
list1=['apple','egg','apple','banana','egg','apple']
counts = Counter(list1)
print(counts)
# Counter({'apple': 3, 'egg': 2, 'banana': 1})

perl -e 'map { $on=$_; s/ /_/; rename($on, $_) or warn $!; } <*>;'

I like the answer of Anacrust, though, by the fact "console.log" is executed twice, I would like to do a small update for src/mylib.js:

let test = {
  foo () { return 'foo' },
  bar () { return 'bar' },
  baz () { return 'baz' }
}

export default test

All other code remains the same...

If you want to do this from code that you are writing as part of a particular view controller, like in response to a button press or something, you can do this:

@IBAction func pushSearchButton(_ sender: UIButton?) {
    if let tabBarController = self.navigationController?.tabBarController  {
        tabBarController.selectedIndex = 1
    }
}

And you can also add code to handle tab switching using the UITabBarControllerDelegate methods. Using tags on the base view controllers of each tab, you can see where you are and act accordingly: For example

func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
    
    // if we didn't change tabs, don't do anything
    if tabBarController.selectedViewController?.tabBarItem.tag ==  viewController.tabBarItem.tag {
        return false
    }
    
    if viewController.tabBarItem.tag == 4096 { // some particular tab
        // do stuff appropriate for a transition to this particular tab
    }
    else if viewController.tabBarItem.tag == 2048 { // some other tab
        // do stuff appropriate for a transition to this other tab
    }
}

What login are you connecting to SQL Server as? You need to connect with a login that has sufficient privileges to create a database. Network Service is probably not good enough, unless you go into SQL Server and add them as a login with sufficient rights.

I was facing the same problem, then in my app.module.ts I updated the file this way,

import { HttpModule } from '@angular/http';
import { HttpClientModule } from '@angular/common/http';

and in the same file (app.module.ts) in my @NgModule imports[]array I wrote this way,

HttpModule,
HttpClientModule

Anyone using AUSKEY from the Australian Tax Office (ATO) should uninstall AUSKEY. This sorted out my JAVA_HOME issues.

It is also no longer required for MAC users. Yah!

How to convert from one date format to another using SimpleDateFormat:

final String OLD_FORMAT = "dd/MM/yyyy";
final String NEW_FORMAT = "yyyy/MM/dd";

// August 12, 2010
String oldDateString = "12/08/2010";
String newDateString;

SimpleDateFormat sdf = new SimpleDateFormat(OLD_FORMAT);
Date d = sdf.parse(oldDateString);
sdf.applyPattern(NEW_FORMAT);
newDateString = sdf.format(d);

Try this with

 std::min_element(v.begin(),v.end())
