Unfortunately there is no such a thing as Lock/Unlock. What you have to do is:

1. Click on "Filter Current Log..."
2. Select the XML tab and click on "Edit query manually"

3. Enter the below query:

   <QueryList>
     <Query Id="0" Path="Security">
       <Select Path="Security">
       *[EventData[Data[@Name='LogonType']='7']
        and
        (System[(EventID='4634')] or System[(EventID='4624')])
        ]</Select>
     </Query>
   </QueryList>
   

That's it

It might be a good practice to define variables like below:

v_departmentid departments.department_id%TYPE;

NOT like below:

v_departmentid NUMBER(4)

playSound is a static method in your class, but you are referring to members like audioSounds or minTime which are not declared static so they would require a SoundManager sm = new SoundManager(); to operate as sm.audioSounds or sm.minTime respectively

Solution:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

Install the vagrant-vbguest plugin by running this command:

vagrant plugin install vagrant-vbguest

1. By using reflection, private methods can be called from test classes. In this case,

   //test method will be like this ...

   public class TestA {
   
     @Test
       public void testMethod() {
   
       A a= new A();
       Method privateMethod = A.class.getDeclaredMethod("method1", null);
       privateMethod.setAccessible(true);
       // invoke the private method for test
       privateMethod.invoke(A, null);
   
       }
   }
   

2. If the private method calls any other private method, then we need to spy the object and stub the another method.The test class will be like ...

   //test method will be like this ...

   public class TestA {
   
     @Test
       public void testMethod() {
   
       A a= new A();
       A spyA = spy(a);
       Method privateMethod = A.class.getDeclaredMethod("method1", null);
       privateMethod.setAccessible(true);
       doReturn("Test").when(spyA, "method2"); // if private method2 is returning string data
       // invoke the private method for test
       privateMethod.invoke(spyA , null);
   
       }
   }
   

**The approach is to combine reflection and spying the object. **method1 and **method2 are private methods and method1 calls method2.

Change SUM(billableDuration) AS NumSecondsDelivered to

sum(cast(billableDuration as bigint)) or

sum(cast(billableDuration as numeric(12, 0))) according to your need.

The resultant type of of Sum expression is the same as the data type used. It throws error at time of overflow. So casting the column to larger capacity data type and then using Sum operation works fine.

You can make sure that the object in question is stringified before passing it to parse function by simply using JSON.stringify() .

Updated your line below,

JSON.parse(JSON.stringify({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false}));

or if you have JSON stored in some variable:

JSON.parse(JSON.stringify(yourJSONobject));

This is the normal behavior, and it's caused by the default <select> style under Firefox : you can't set line-height, then you need to play on padding when you want to have a customized <select>.

Example, with results under Firefox 25 / Chrome 31 / IE 10 :

<select>
  <option>Default</option>
  <option>Default</option>
  <option>Default</option>
</select>

<select class="form-control">
  <option>Bootstrap</option>
  <option>Bootstrap</option>
  <option>Bootstrap</option>
</select>

<select class="form-control custom">
  <option>Custom</option>
  <option>Custom</option>
  <option>Custom</option>
</select>

select.custom {
  padding: 0px;
}

Just use a different browser. Follow the steps given below to install Chrome extensions on your Android device.

Step 1: Open Google Play Store and download Yandex Browser. Install the browser on your phone.

Step 2: In the URL box of your new browser, open 'chrome.google.com/webstore’ by entering the same in the URL address.

Step 3: Look for the Chrome extension that you want and once you have it, tap on 'Add to Chrome.’

The added Chrome extension will now be automatically added to the Yandex browser.

Try this

public class NetworkUtil {
    public static final int TYPE_WIFI = 1;
    public static final int TYPE_MOBILE = 2;
    public static final int TYPE_NOT_CONNECTED = 0;
    public static final int NETWORK_STATUS_NOT_CONNECTED = 0;
    public static final int NETWORK_STATUS_WIFI = 1;
    public static final int NETWORK_STATUS_MOBILE = 2;

    public static int getConnectivityStatus(Context context) {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
        if (null != activeNetwork) {
            if(activeNetwork.getType() == ConnectivityManager.TYPE_WIFI)
                return TYPE_WIFI;

            if(activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE)
                return TYPE_MOBILE;
        } 
        return TYPE_NOT_CONNECTED;
    }

    public static int getConnectivityStatusString(Context context) {
        int conn = NetworkUtil.getConnectivityStatus(context);
        int status = 0;
        if (conn == NetworkUtil.TYPE_WIFI) {
            status = NETWORK_STATUS_WIFI;
        } else if (conn == NetworkUtil.TYPE_MOBILE) {
            status = NETWORK_STATUS_MOBILE;
        } else if (conn == NetworkUtil.TYPE_NOT_CONNECTED) {
            status = NETWORK_STATUS_NOT_CONNECTED;
        }
        return status;
    }
}

And for the BroadcastReceiver

public class NetworkChangeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(final Context context, final Intent intent) {

        int status = NetworkUtil.getConnectivityStatusString(context);
        Log.e("Sulod sa network reciever", "Sulod sa network reciever");
        if ("android.net.conn.CONNECTIVITY_CHANGE".equals(intent.getAction())) {
            if (status == NetworkUtil.NETWORK_STATUS_NOT_CONNECTED) {
                new ForceExitPause(context).execute();
            } else {
                new ResumeForceExitPause(context).execute();
            }
       }
    }
}

Don't forget to put this into your AndroidManifest.xml

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
 <uses-permission android:name="android.permission.INTERNET" />
 <receiver
        android:name="NetworkChangeReceiver"
        android:label="NetworkChangeReceiver" >
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
            <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
        </intent-filter>
    </receiver>

Hope this will help you Cheers!

Temporal types are the set of time-based types that can be used in persistent state mappings.

The list of supported temporal types includes the three java.sql types java.sql.Date, java.sql.Time, and java.sql.Timestamp, and it includes the two java.util types java.util.Date and java.util.Calendar.

The java.sql types are completely hassle-free. They act just like any other simple mapping type and do not need any special consideration.

The two java.util types need additional metadata, however, to indicate which of the JDBC java.sql types to use when communicating with the JDBC driver. This is done by annotating them with the @Temporal annotation and specifying the JDBC type as a value of the TemporalType enumerated type.

There are three enumerated values of DATE, TIME, and TIMESTAMP to represent each of the java.sql types.

If the user exists you can get the user in user_object else user_object will be None.

try:
    user_object = User.objects.get(email = cleaned_info['username'])
except User.DoesNotExist:
    user_object = None
if user_object:
    # user exist
    pass
else:
    # user does not exist
    pass

try:

$('#search input.keywords').bind('change', function(){
    //this.value.toUpperCase();
    //EDIT: As  Mike Samuel suggested, this will be more appropriate for the job
    this.value = this.value.toLocaleUpperCase();
} );

Visit https://developers.google.com/mobile/add and try to fill "Android package name". In some cases it can write error: "Invalid Android package name".

In https://developer.android.com/studio/build/application-id.html it is written:

And although the application ID looks like a traditional Java package name, the naming rules for the application ID are a bit more restrictive:

• It must have at least two segments (one or more dots).
• Each segment must start with a letter.
• All characters must be alphanumeric or an underscore [a-zA-Z0-9_].

So, "0com.example.app" and "com.1example.app" are errors.

You can Use the tool : Eclipse Memory Analyzer Tool http://www.eclipse.org/mat/ .

It is very useful.

We also can create UrlHelper from RequestContext which we can get from MvcHandler itself. Therefore I beleive for someone who wants to keep this logic in Razor templates following way would be helpful:

1. In project root create a folder named AppCode.
2. Create a file there named HtmlHelpers.cshtml

3. Create a helper in there:

   @helper MenuItem(string action, string controller)
   {
        var mvcHandler = Context.CurrentHandler as MvcHandler;
        if (mvcHandler != null)
        {
            var url = new UrlHelper(mvcHandler.RequestContext);
            var routeData = mvcHandler.RequestContext.RouteData;
            var currentAction = routeData.Values["action"].ToString();
            var currentController = routeData.Values["controller"].ToString();
            var isCurrent = string.Equals(currentAction, action, StringComparison.InvariantCultureIgnoreCase) &&
                            string.Equals(currentController, controller, StringComparison.InvariantCultureIgnoreCase);
   
           <div class="@(isCurrent ? "active" : "")">
               <div>@url.Action(action, controller)</div>
           </div>
        }   
   }
   

4. Then we can use on our views like this:

   @HtmlHelpers.MenuItem("Default", "Home")
   

Hope that it helps to someone.

Set resolution in android x86

Libvirt/qemu

Temporarily

• Add nomodeset and vga=ask to android x86 grub entry's kernel loading options;
• Find your best resolution and note the code you used.

Permanently

• Convert that code to decimal from hex;
• Add vga=decimal_code to your preferred entry in /mnt/grub/menu.lst (mounted if android is started in debug mode).

Code:

while ($rows = mysql_fetch_array($query)):
       $name = $rows['Name'];
       $address = $rows['Address'];
       $email = $rows['Email'];
       $subject = $rows['Subject'];
       $comment = $rows['Comment']
       echo "$name<br>$address<br>$email<br>$subject<br>$comment<br><br>";
endwhile;

I had this other solution (I'm posting it in case someone else as me is using the following method from the model):

class onlyUserIsActiveField(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(onlyUserIsActiveField, self).__init__(*args, **kwargs)
        self.fields['is_active'].initial = False

    class Meta:
        model = User
        fields = ['is_active']
        labels = {'is_active': 'Is Active'}
        widgets = {
            'is_active': forms.CheckboxInput( attrs={
                            'class':          'form-control bootstrap-switch',
                            'data-size':      'mini',
                            'data-on-color':  'success',
                            'data-on-text':   'Active',
                            'data-off-color': 'danger',
                            'data-off-text':  'Inactive',
                            'name':           'is_active',

            })
        }

The initial is definded on the __init__ function as self.fields['is_active'].initial = False

If i is the int, then

char c = i;

makes it a char. You might want to add a check that the value is <128 if it comes from an untrusted source. This is best done with isascii from <ctype.h>, if available on your system (see @Steve Jessop's comment to this answer).

You should not execute resource intensive tasks in the main thread. It will make the UI unresponsive and you will get an ANR. It seems like you will be doing resource intensive stuff and want the user to see the ProgressDialog. You can take a look at http://developer.android.com/reference/android/os/AsyncTask.html to do resource intensive tasks. It also shows you how to use a ProgressDialog.

This calculator does not have any modulo function. However there is quite simple way how to compute modulo using display mode ab/c (instead of traditional d/c).

How to switch display mode to ab/c:

• Go to settings (Shift + Mode).
• Press arrow down (to view more settings).
• Select ab/c (number 1).

Now do your calculation (in comp mode), like 50 / 3 and you will see 16 2/3, thus, mod is 2. Or try 54 / 7 which is 7 5/7 (mod is 5). If you don't see any fraction then the mod is 0 like 50 / 5 = 10 (mod is 0).

The remainder fraction is shown in reduced form, so 60 / 8 will result in 7 1/2. Remainder is 1/2 which is 4/8 so mod is 4.

EDIT: As @lawal correctly pointed out, this method is a little bit tricky for negative numbers because the sign of the result would be negative.

For example -121 / 26 = -4 17/26, thus, mod is -17 which is +9 in mod 26. Alternatively you can add the modulo base to the computation for negative numbers: -121 / 26 + 26 = 21 9/26 (mod is 9).

EDIT2: As @simpatico pointed out, this method will not work for numbers that are out of calculator's precision. If you want to compute say 200^5 mod 391 then some tricks from algebra are needed. For example, using rule (A * B) mod C = ((A mod C) * B) mod C we can write:

200^5 mod 391 = (200^3 * 200^2) mod 391 = ((200^3 mod 391) * 200^2) mod 391 = 98

There are several ways. One way is to use save() to save the exact object. e.g. for data frame foo:

save(foo,file="data.Rda")

Then load it with:

load("data.Rda")

You could also use write.table() or something like that to save the table in plain text, or dput() to obtain R code to reproduce the table.

In a navigation based application you can change color

NSArray *ver = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];
if ([[ver objectAtIndex:0] intValue] >= 7) {
    self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];
    self.navigationController.navigationBar.translucent = NO;
} else {
    self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];
}

1) You can put your favicon where you want and add this tag to your page head

<link rel="shortcut icon" href="images/favicon.ico" type="image/x-icon" />

although some browsers will try to get the favicon from /favicon.ico by default, so you should use the IgnoreRoute.

2) If a browser makes a request for the favicon in another directory it will get a 404 error wich is fine and if you have the link tag in answer 1 in your master page the browser will get the favicon you want.

You might want to look at csounds, also. It has several API's, including Python. It might be able to interact with an A-D interface and gather sound samples.

Once sockaddr cast to sockaddr_in, it becomes this:

struct sockaddr_in {
    u_short     sin_family;
    u_short     sin_port;
    struct      in_addr sin_addr;
    char        sin_zero[8];
};

That means sql group by 1st column in your select clause, we always use this GROUP BY 1 together with ORDER BY 1, besides you can also use like this GROUP BY 1,2,3.., of course it is convenient for us but you need to pay attention to that condition the result may be not what you want if some one has modified your select columns, and it's not visualized

From your description, it looks like that you want to "reserve" the allocated storage space of vector t_Names.

Take note that resize initialize the newly allocated vector where reserve just allocates but does not construct. Hence, 'reserve' is much faster than 'resize'

You can refer to the documentation regarding the difference of resize and reserve

application/force-download is not a standard MIME type. It's a hack supported by some browsers, added fairly recently.

Your question doesn't really make any sense. It's like asking why Internet Explorer 4 doesn't support the latest CSS 3 functionality.

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

public class SortingArray {
public static void main(String[] args) {

int[] a={3,7,9,5,1,4,0,2,8,6};

boolean isSwapped=true;


System.out.println(" before sorting the array: ");

for(int i=0;i<a.length;i++)
{
    System.out.print(a[i]);
}
System.out.println("");

        temp=a[i];

        a[i]=a[i+1];

        a[i+1]=temp;

    }



}


}while(isSwapped);


System.out.println("after sorting the array: ");

If you cannot use spark-csv, you can do the following:

df.rdd.map(lambda x: ",".join(map(str, x))).coalesce(1).saveAsTextFile("file.csv")

If you need to handle strings with linebreaks or comma that will not work. Use this:

import csv
import cStringIO

def row2csv(row):
    buffer = cStringIO.StringIO()
    writer = csv.writer(buffer)
    writer.writerow([str(s).encode("utf-8") for s in row])
    buffer.seek(0)
    return buffer.read().strip()

df.rdd.map(row2csv).coalesce(1).saveAsTextFile("file.csv")

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

You probably don't want to pass the car object as a parameter, try just passing car.id. What do you get when you inspect(params) after clicking "Add to cart"?

Here's a flexible method, written in vanilla JS, that allows you to run a CSS selector query over only the direct children of an element:

var count = 0;
function queryChildren(element, selector) {
  var id = element.id,
      guid = element.id = id || 'query_children_' + count++,
      attr = '#' + guid + ' > ',
      selector = attr + (selector + '').replace(',', ',' + attr, 'g');
  var result = element.parentNode.querySelectorAll(selector);
  if (!id) element.removeAttribute('id');
  return result;
}

All of the above with fallback to 'en':

$lang = substr(explode(',',$_SERVER['HTTP_ACCEPT_LANGUAGE'])[0],0,2)?:'en';

...or with default language fallback and known language array:

function lang( $l = ['en'], $u ){
    return $l[
        array_keys(
            $l,
            substr(
                explode(
                    ',',
                    $u ?: $_SERVER['HTTP_ACCEPT_LANGUAGE']
                )[0],
                0,
                2
            )
        )[0]
    ] ?: $l[0];
}

One Line:

function lang($l=['en'],$u){return $l[array_keys($l,substr(explode(',',$u?:$_SERVER['HTTP_ACCEPT_LANGUAGE'])[0],0,2))[0]]?:$l[0];}

Examples:

// first known lang is always default
$_SERVER['HTTP_ACCEPT_LANGUAGE'] = 'en-us';
lang(['de']); // 'de'
lang(['de','en']); // 'en'

// manual set accept-language
lang(['de'],'en-us'); // 'de'
lang(['de'],'de-de, en-us'); // 'de'
lang(['en','fr'],'de-de, en-us'); // 'en'
lang(['en','fr'],'fr-fr, en-us'); // 'fr'
lang(['de','en'],'fr-fr, en-us'); // 'de'

Go to application/config/autoload.php

$autoload['helper'] = array('url'); 

add this on top anywhere

and at this in controller

function __construct()
{
    parent::__construct();
$this->load->helper('url');

}

I did following steps to downgrade Gradle back to the original version:

• I deleted content of '.gradle/caches' folder in user home directory (windows).
• I deleted content of '.gradle' folder in my project root.
• I checked that Gradle version is properly set in 'Project' option of 'Project Structure' in Android Studio.
• I selected 'Use default gradle wrapper' option in 'Settings' in Android Studio, just search for gradle key word to find it.

Probably last step is enough as in my case the path to the new Gradle distribution was hardcoded there under 'Gradle home' option.

The two structs are different. When you initialize the first struct, about 40 bytes of memory are allocated. When you initialize the second struct, about 10 bytesof memory are allocated. (Actual amount is architecture dependent)

You can use the string literals (string constants) to initalize character arrays. This is why

person p = {"John", "Doe",30};

works in the first example.

You cannot assign (in the conventional sense) a string in C.

The string literals you have ("John") are loaded into memory when your code executes. When you initialize an array with one of these literals, then the string is copied into a new memory location. In your second example, you are merely copying the pointer to (location of) the string literal. Doing something like:

char* string = "Hello";
*string = 'C'

might cause compile or runtime errors (I am not sure.) It is a bad idea because you are modifying the literal string "Hello" which, for example on a microcontroler, could be located in read-only memory.

General purpose normalisation function to format any timestamp from any timezone to other. Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')

/**
 * Convert Datetime from any given olsonzone to other.
 * @return datetime in user specified format
 */

function datetimeconv($datetime, $from, $to)
{
    try {
        if ($from['localeFormat'] != 'Y-m-d H:i:s') {
            $datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
        }
        $datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
        $datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
        return $datetime->format($to['localeFormat']);
    } catch (\Exception $e) {
        return null;
    }
}

Usage:

$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];

$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];

datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

If you're using Ionic and the Push and Console plugins that's the problem. Remove the cordova console plugin (which is deprecated) and the error will disappear.

The linker error is saying that a library is duplicated which is, in fact, true because the console plugin is already in cordova-ios 4.5+

It took me a couple of hours to figure this out!

length(unique(df$col)) is the most simple way I can see.

You can create an array with all elements from a given Swift Set simply with

let array = Array(someSet)

This works because Set conforms to the SequenceType protocol and an Array can be initialized with a sequence. Example:

let mySet = Set(["a", "b", "a"])  // Set<String>
let myArray = Array(mySet)        // Array<String>
print(myArray) // [b, a]

Yes, JavaScript variables will exist in the scope they are created.

var bannerID = 55;

<input id="EditBanner" type="button" 
  value="Edit Image" onclick="EditBanner(bannerID);"/>


function EditBanner(id) {
   //Do something with id
}

If you use event handlers and jQuery it is simple also

$("#EditBanner").click(function() {
   EditBanner(bannerID);
});

You cannot style a variable such as $ip['countryName']

You can only style elements like p,div, etc, or classes and ids.

If you want to style $ip['countryName'] there are several ways.

You can echo it within an element:

echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';

If you want to style both the variables the same style, then set a class like:

echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';

You could also embed the variables within your actual html rather than echoing them out within the code.

$city = $ip['cityName'];  
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>

This thread is a little old, and I am brand new to this, but I think I found the preferred solution.

First, I assume that you are using Eclipse and the Android ADT plugin.

In Eclipse, choose Window/Android SDK Manager. In the display, expand the entry for the MOST RECENT PLATFORM, even if that is not the platform that your are developing for. As of Jan 2012, it is "Android 4.0.3 (API 15)". When expanded, the first entry is "Documentation for Android SDK" Click the checkbox next to it, and then click the "Install" button.

When done, you should have a new directory in your "android-sdks" called "doc". Look for "offline.html" in there. Since this is packaged with the most recent version, it will document the most recent platform, but it should also show the APIs for previous versions.

You should know that CPython doesn't really support multithreading (it does, but not optimal) because of the Global Interpreter Lock. It also has no Optimisation mechanisms for recursion, and has many other limitations that other implementations and libraries try to fill.

You should take a look at this page on the python wiki.

Look at the code snippets on this page, it'll give you a good idea of what an interpreter is.

USE[Database] SELECT TABLE_NAME,TABLE_SCHEMA,[Column_Name],[Data_type] FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA='dbo'

The CBO builds a decision tree, estimating the costs of each possible execution path available per query. The costs are set by the CPU_cost or I/O_cost parameter set on the instance. And the CBO estimates the costs, as best it can with the existing statistics of the tables and indexes that the query will use. You should not tune your query based on cost alone. Cost allows you to understand WHY the optimizer is doing what it does. Without cost you could figure out why the optimizer chose the plan it did. Lower cost does not mean a faster query. There are cases where this is true and there will be cases where this is wrong. Cost is based on your table stats and if they are wrong the cost is going to be wrong.

When tuning your query, you should take a look at the cardinality and the number of rows of each step. Do they make sense? Is the cardinality the optimizer is assuming correct? Is the rows being return reasonable. If the information present is wrong then its very likely the optimizer doesn't have the proper information it needs to make the right decision. This could be due to stale or missing statistics on the table and index as well as cpu-stats. Its best to have stats updated when tuning a query to get the most out of the optimizer. Knowing your schema is also of great help when tuning. Knowing when the optimizer chose a really bad decision and pointing it in the correct path with a small hint can save a load of time.

In an application level, here are something a developer can do:

From server side:

1. Check if load balancer(if you have),works correctly.

2. Turn slow TCP timeouts into 503 Fast Immediate response, if you load balancer work correctly, it should pick the working resource to serve, and it's better than hanging there with unexpected error massages.

Eg: If you are using node server, u can use toobusy from npm. Implementation something like:

var toobusy = require('toobusy');
app.use(function(req, res, next) {
  if (toobusy()) res.send(503, "I'm busy right now, sorry.");
  else next();
});

Why 503? Here are some good insights for overload: http://ferd.ca/queues-don-t-fix-overload.html

We can do some work in client side too:

1. Try to group calls in batch, reduce the traffic and total requests number b/w client and server.

2. Try to build a cache mid-layer to handle unnecessary duplicates requests.

In my case it was a simple case of removing IIS because Windows 10 comes with IIS (Internet Information Service) pre installed - that conflicts with XAMPP because these both servers try to use the port 80. If you don't want to use IIS and keep using XAMPP

1. Go to run/search in Windows 10
2. Search for 'optional features'
3. On that list untick Internet Information Service (IIS)

Then restart.

Open cmd type adb shell then press enter. Type ls to view files list.

You have to specify project_id:

reverse('edit_project', kwargs={'project_id':4})

Here is how I got this working

$.ajax({

  success: function(data) {
    var blob=new Blob([data]);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="<FILENAME_TO_SAVE_WITH_EXTENSION>";
    link.click();

For React Native, React, and For Node project, below one is working

yarn add  query-string

import queryString from 'query-string';

const parsed = queryString.parseUrl("https://pokeapi.co/api/v2/pokemon?offset=10&limit=10");

console.log(parsed.offset) will display 10

This is a segfault due to following a null pointer trying to find code to run (that is, during an instruction fetch).

If this were a program, not a shared library

Run addr2line -e yourSegfaultingProgram 00007f9bebcca90d (and repeat for the other instruction pointer values given) to see where the error is happening. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb.

Since it's a shared library

You're hosed, unfortunately; it's not possible to know where the libraries were placed in memory by the dynamic linker after-the-fact. Reproduce the problem under gdb.

What the error means

Here's the breakdown of the fields:

• address (after the at) - the location in memory the code is trying to access (it's likely that 10 and 11 are offsets from a pointer we expect to be set to a valid value but which is instead pointing to 0)
• ip - instruction pointer, ie. where the code which is trying to do this lives
• sp - stack pointer

• error - An error code for page faults; see below for what this means on x86.

  /*
   * Page fault error code bits:
   *
   *   bit 0 ==    0: no page found       1: protection fault
   *   bit 1 ==    0: read access         1: write access
   *   bit 2 ==    0: kernel-mode access  1: user-mode access
   *   bit 3 ==                           1: use of reserved bit detected
   *   bit 4 ==                           1: fault was an instruction fetch
   */
  

Be sure to configure the 'default' key in app/config/database.php

For postgres, this would be 'default' => 'postgres',

If you are receiving a [PDOException] could not find driver error, check to see if you have the correct PHP extensions installed. You need pdo_pgsql.so and pgsql.so installed and enabled. Instructions on how to do this vary between operating systems.

For Windows, the pgsql extensions should come pre-downloaded with the official PHP distribution. Just edit your php.ini and uncomment the lines extension=pdo_pgsql.so and extension=pgsql.so

Also, in php.ini, make sure extension_dir is set to the proper directory. It should be a folder called extensions or ext or similar inside your PHP install directory.

Finally, copy libpq.dll from C:\wamp\bin\php\php5.*\ into C:\wamp\bin\apache*\bin and restart all services through the WampServer interface.

If you still get the exception, you may need to add the postgres \bin directory to your PATH:

1. System Properties -> Advanced tab -> Environment Variables
2. In 'System variables' group on lower half of window, scroll through and find the PATH entry.
3. Select it and click Edit
4. At the end of the existing entry, put the full path to your postgres bin directory. The bin folder should be located in the root of your postgres installation directory.
5. Restart any open command prompts, or to be certain, restart your computer.

This should hopefully resolve any problems. For more information see:

• http://php.net/manual/en/install.pecl.windows.php
• http://webcheatsheet.com/php/install_and_configure.php#extsetup

You don't put a component in directives

You register it in @NgModule declarations:

@NgModule({
  imports: [ BrowserModule ],
  declarations: [ App , MyChildComponent ],
  bootstrap: [ App ]
})

and then You just put it in the Parent's Template HTML as : <my-child></my-child>

That's it.

FPM is a process manager to manage the FastCGI SAPI (Server API) in PHP.

Basically, it replaces the need for something like SpawnFCGI. It spawns the FastCGI children adaptively (meaning launching more if the current load requires it).

Otherwise, there's not much operating difference between it and FastCGI (The request pipeline from start of request to end is the same). It's just there to make implementing it easier.

find -L /var/www/ -type l

# man find

-L     Follow  symbolic links.  When find examines or prints information about files, the information used shall be taken from the

properties of the file to which the link points, not from the link itself (unless it is a broken symbolic link or find is unable to examine the file to which the link points). Use of this option implies -noleaf. If you later use the -P option, -noleaf will still be in effect. If -L is in effect and find discovers a symbolic link to a subdirectory during its search, the subdirectory pointed to by the symbolic link will be searched.

This works for SQL Server Management Studio also.

As an option, you can create abstract test class covering logic inside abstract class and extend it for each subclass test. So that in this way you can ensure this logic will be tested for each child separately.

A typical way would be to use stringstream:

#include <iomanip>
#include <sstream>

double pi = 3.14159265359;
std::stringstream stream;
stream << std::fixed << std::setprecision(2) << pi;
std::string s = stream.str();

See fixed

Use fixed floating-point notation

Sets the floatfield format flag for the str stream to fixed.

When floatfield is set to fixed, floating-point values are written using fixed-point notation: the value is represented with exactly as many digits in the decimal part as specified by the precision field (precision) and with no exponent part.

and setprecision.

For conversions of technical purpose, like storing data in XML or JSON file, C++17 defines to_chars family of functions.

Assuming a compliant compiler (which we lack at the time of writing), something like this can be considered:

#include <array>
#include <charconv>

double pi = 3.14159265359;
std::array<char, 128> buffer;
auto [ptr, ec] = std::to_chars(buffer.data(), buffer.data() + buffer.size(), pi,
                               std::chars_format::fixed, 2);
if (ec == std::errc{}) {
    std::string s(buffer.data(), ptr);
    // ....
}
else {
    // error handling
}

Convert an ArrayList to an object array

ArrayList has a constructor that takes a Collection, so the common idiom is:

List<T> list = new ArrayList<T>(Arrays.asList(array));

Which constructs a copy of the list created by the array.

now, Arrays.asList(array) will wrap the array, so changes to the list will affect the array, and visa versa. Although you can't add or remove

elements from such a list.

If you are able to send the payload in JSON, this is a most convenient way to read the playload:

Example data class:

public class Person {
    String firstName;
    String lastName;
    // Getters and setters ...
}

Example payload (request body):

{ "firstName" : "John", "lastName" : "Doe" }

Code to read payload in servlet (requires com.google.gson.*):

Person person = new Gson().fromJson(request.getReader(), Person.class);

That's all. Nice, easy and clean. Don't forget to set the content-type header to application/json.

Update in ASP.NET Core Version >= 2.0

In the Controller:

public class YourControllerNameController : Controller
{
    private readonly UserManager<ApplicationUser> _userManager;
    
    public YourControllerNameController(UserManager<ApplicationUser> userManager)
    {
        _userManager = userManager;
    }

    public async Task<IActionResult> YourMethodName()
    {
        var userId =  User.FindFirstValue(ClaimTypes.NameIdentifier) // will give the user's userId
        var userName =  User.FindFirstValue(ClaimTypes.Name) // will give the user's userName
        
        // For ASP.NET Core <= 3.1
        ApplicationUser applicationUser = await _userManager.GetUserAsync(User);
        string userEmail = applicationUser?.Email; // will give the user's Email

       // For ASP.NET Core >= 5.0
       var userEmail =  User.FindFirstValue(ClaimTypes.Email) // will give the user's Email
    }
}

In some other class:

public class OtherClass
{
    private readonly IHttpContextAccessor _httpContextAccessor;
    public OtherClass(IHttpContextAccessor httpContextAccessor)
    {
       _httpContextAccessor = httpContextAccessor;
    }

   public void YourMethodName()
   {
      var userId = _httpContextAccessor.HttpContext.User.FindFirstValue(ClaimTypes.NameIdentifier);
   }
}

Then you should register IHttpContextAccessor in the Startup class as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Or you can also register as follows

    services.AddHttpContextAccessor();
}

For more readability write extension methods as follows:

public static class ClaimsPrincipalExtensions
{
    public static T GetLoggedInUserId<T>(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        var loggedInUserId = principal.FindFirstValue(ClaimTypes.NameIdentifier);

        if (typeof(T) == typeof(string))
        {
            return (T)Convert.ChangeType(loggedInUserId, typeof(T));
        }
        else if (typeof(T) == typeof(int) || typeof(T) == typeof(long))
        {
            return loggedInUserId != null ? (T)Convert.ChangeType(loggedInUserId, typeof(T)) : (T)Convert.ChangeType(0, typeof(T));
        }
        else
        {
            throw new Exception("Invalid type provided");
        }
    }

    public static string GetLoggedInUserName(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Name);
    }

    public static string GetLoggedInUserEmail(this ClaimsPrincipal principal)
    {
        if (principal == null)
            throw new ArgumentNullException(nameof(principal));

        return principal.FindFirstValue(ClaimTypes.Email);
    }
}

Then use as follows:

public class YourControllerNameController : Controller
{
    public IActionResult YourMethodName()
    {
        var userId = User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
        var userName = User.GetLoggedInUserName();
        var userEmail = User.GetLoggedInUserEmail();
    }
}

public class OtherClass
{
     private readonly IHttpContextAccessor _httpContextAccessor;
     public OtherClass(IHttpContextAccessor httpContextAccessor)
     {
         _httpContextAccessor = httpContextAccessor;
     }

     public void YourMethodName()
     {
         var userId = _httpContextAccessor.HttpContext.User.GetLoggedInUserId<string>(); // Specify the type of your UserId;
     }
}

Just adding to the correct answer you can set the timeout with the arrow function like this:

it('Some test', () => {

}).timeout(5000)

There could be a mistake in @JARH's answer in the case of a multivariable regression. (I do not have enough reputation to comment.)

In the following line:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-1))) for i in ts_b],

the t-values follows a chi-squared distribution of degree len(newX)-1 instead of following a chi-squared distribution of degree len(newX)-len(newX.columns)-1.

So this should be:

p_values =[2*(1-stats.t.cdf(np.abs(i),(len(newX)-len(newX.columns)-1))) for i in ts_b]

(See t-values for OLS regression for more details)

Using TinyMCE editor, the only way I was able to remove all borders was to use border:hidden in the style like this:

<style>
table, tr {border:hidden;}
td, th {border:hidden;}
</style>

And in the HTML like this:

<table style="border:hidden;"</table>

please check out the IPython configuration system, implemented via traitlets for the type enforcement you are doing manually.

Cut and pasted here to comply with SO guidelines for not just dropping links as the content of links changes over time.

traitlets documentation

Here are the main requirements we wanted our configuration system to have:

Support for hierarchical configuration information.

Full integration with command line option parsers. Often, you want to read a configuration file, but then override some of the values with command line options. Our configuration system automates this process and allows each command line option to be linked to a particular attribute in the configuration hierarchy that it will override.

Configuration files that are themselves valid Python code. This accomplishes many things. First, it becomes possible to put logic in your configuration files that sets attributes based on your operating system, network setup, Python version, etc. Second, Python has a super simple syntax for accessing hierarchical data structures, namely regular attribute access (Foo.Bar.Bam.name). Third, using Python makes it easy for users to import configuration attributes from one configuration file to another. Fourth, even though Python is dynamically typed, it does have types that can be checked at runtime. Thus, a 1 in a config file is the integer ‘1’, while a '1' is a string.

A fully automated method for getting the configuration information to the classes that need it at runtime. Writing code that walks a configuration hierarchy to extract a particular attribute is painful. When you have complex configuration information with hundreds of attributes, this makes you want to cry.

Type checking and validation that doesn’t require the entire configuration hierarchy to be specified statically before runtime. Python is a very dynamic language and you don’t always know everything that needs to be configured when a program starts.

To acheive this they basically define 3 object classes and their relations to each other:

1) Configuration - basically a ChainMap / basic dict with some enhancements for merging.

2) Configurable - base class to subclass all things you'd wish to configure.

3) Application - object that is instantiated to perform a specific application function, or your main application for single purpose software.

In their words:

Application: Application

An application is a process that does a specific job. The most obvious application is the ipython command line program. Each application reads one or more configuration files and a single set of command line options and then produces a master configuration object for the application. This configuration object is then passed to the configurable objects that the application creates. These configurable objects implement the actual logic of the application and know how to configure themselves given the configuration object.

Applications always have a log attribute that is a configured Logger. This allows centralized logging configuration per-application. Configurable: Configurable

A configurable is a regular Python class that serves as a base class for all main classes in an application. The Configurable base class is lightweight and only does one things.

This Configurable is a subclass of HasTraits that knows how to configure itself. Class level traits with the metadata config=True become values that can be configured from the command line and configuration files.

Developers create Configurable subclasses that implement all of the logic in the application. Each of these subclasses has its own configuration information that controls how instances are created.

why dont we use something like

pgrep -f $cmd || $cmd

It is like

<?php
use yii\helpers\ArrayHelper;
use backend\models\Standard;

ArrayHelper in Yii2 replaces the CHtml list data in Yii 1.1.[Please load array data from your controller]

EDIT

Load data from your controller.

Controller

A more elegant/concise solution:

$(document).on('keydown',function(e){
  var $target = $(e.target||e.srcElement);
  if(e.keyCode == 8 && !$target.is('input,[contenteditable="true"],textarea'))
  {
    e.preventDefault();
  }
})

This is documented on the doxygen website, but to summarize here:

You can use doxygen to document your Python code. You can either use the Python documentation string syntax:

"""@package docstring
Documentation for this module.

More details.
"""

def func():
    """Documentation for a function.

    More details.
    """
    pass

In which case the comments will be extracted by doxygen, but you won't be able to use any of the special doxygen commands.

Or you can (similar to C-style languages under doxygen) double up the comment marker (#) on the first line before the member:

## @package pyexample
#  Documentation for this module.
#
#  More details.

## Documentation for a function.
#
#  More details.
def func():
    pass

In that case, you can use the special doxygen commands. There's no particular Python output mode, but you can apparently improve the results by setting OPTMIZE_OUTPUT_JAVA to YES.

Honestly, I'm a little surprised at the difference - it seems like once doxygen can detect the comments in ## blocks or """ blocks, most of the work would be done and you'd be able to use the special commands in either case. Maybe they expect people using """ to adhere to more Pythonic documentation practices and that would interfere with the special doxygen commands?

I used below ms sql script pattern several times successfully which uses Try-Catch,Commit Transaction- Rollback Transaction,Error Tracking.

Your TRY block will be as follows

 BEGIN TRY
 BEGIN TRANSACTION T
 ----
 //your script block
 ----
 COMMIT TRANSACTION T 
 END TRY

Your CATCH block will be as follows

BEGIN CATCH
DECLARE @ErrMsg NVarChar(4000), 
        @ErrNum Int, 
        @ErrSeverity Int, 
        @ErrState Int, 
        @ErrLine Int, 
        @ErrProc NVarChar(200)
 SELECT @ErrNum = Error_Number(), 
       @ErrSeverity = Error_Severity(), 
       @ErrState = Error_State(), 
       @ErrLine = Error_Line(), 
       @ErrProc = IsNull(Error_Procedure(), '-')
 SET @ErrMsg = N'ErrLine: ' + rtrim(@ErrLine) + ', proc: ' + RTRIM(@ErrProc) + ', 
       Message: '+ Error_Message()

Your ROLLBACK script will be part of CATCH block as follows

IF (@@TRANCOUNT) > 0 
BEGIN
PRINT 'ROLLBACK: ' + SUBSTRING(@ErrMsg,1,4000)
ROLLBACK TRANSACTION T
END
ELSE
BEGIN
PRINT SUBSTRING(@ErrMsg,1,4000);   
END

END CATCH

Above different script blocks you need to use as one block. If any error happens in the TRY block it will go the the CATCH block. There it is setting various details about the error number,error severity,error line ..etc. At last all these details will get append to @ErrMsg parameter. Then it will check for the count of transaction (@@TRANCOUNT >0) , ie if anything is there in the transaction for rollback. If it is there then show the error message and ROLLBACK TRANSACTION. Otherwise simply print the error message.

We have kept our COMMIT TRANSACTION T script towards the last line of TRY block in order to make sure that it should commit the transaction(final change in the database) only after all the code in the TRY block has run successfully.

What...

A methodology for automaticaly testing code against a battery of tests, designed to enforce desired outcomes and manage change.

A "unit" in this sense is the smallest atomic component of the code that makes sense to test, typically a method of some class for example. Part of this process is building up stub objects (or "mocks") which allow you to work with a unit as an independant object.

How...

Almost always, the process of unit-testing is built into an IDE (or through extensions) such that it executes the tests with every compile. A number of frameworks exist for assisting the creation of unit tests (and indeed mock objcts), often named fooUnit (cf. jUnit, xUnit, nUnit). These frameworks provide a formalised way to create tests.

As a process, test driven development (TDD) is often the motivation for unit testing (but unit testing does not require TDD) which supposes that the tests are a part of the spec definition, and therefore requires that they are written first, with code only written to "solve" these tests.

When...

Almost always. Very small, throwaway projects may not be worth it, but only if you're quite sure they really are throwaway. In theory every object orientated program is unit testable, but some design pattrns make this difficult. Notoriously, the singleton pattern is problematic, where conversely dependancy injection frameworks are very much unit testing oriented.

There is an operator missing, likely a *:

-3.7 need_something_here (prof[x])

The "is not callable" occurs because the parenthesis -- and lack of operator which would have switched the parenthesis into precedence operators -- make Python try to call the result of -3.7 (a float) as a function, which is not allowed.

The parenthesis are also not needed in this case, the following may be sufficient/correct:

-3.7 * prof[x]

As Legolas points out, there are other things which may need to be addressed:

2.25 * (1 - math.pow(math.e, (-3.7(prof[x])/2.25))) * (math.e, (0/2.25)))
                                  ^-- op missing
                                                    extra parenthesis --^
               valid but questionable float*tuple --^
                                     expression yields 0.0 always --^

ls | xargs find 2>/dev/null | egrep /\.git$ | xargs rm -rf

This command (and it is just one command) will recursively remove .git directories (and files) that are in a directory without deleting the top-level git repo, which is handy if you want to commit all of your files without managing any submodules.

find 2>/dev/null | egrep /\.git$ | xargs rm -rf

This command will do the same thing, but will also delete the .git folder from the top-level directory.

Well, I wanted to push a 219 MB solution, but I had no luck with

git config --global http.postBuffer 524288000

And what's the point of having a 525 MB post buffer anyway? it's silly. So I looked at the git error below:

Total 993 (delta 230), reused 0 (delta 0)
POST git-receive-pack (5173245 bytes)
error: fatal: RPC failed; curl 56 SSL read: error:00000000:lib(0):func(0):reason(0), errno 10054

So git want's to post 5 MB, then I made the post buffer 6 MB, and it works

git config --global http.postBuffer 6291456

I use this command for simple rotate a file:

mv output.log `date +%F`-output.log

In local folder I have 2019-09-25-output.log

var logged_in = false;
logged_in = !logged_in;

Faced similar issue, and here is the solution

Example :

1. In elasticsearch.yml add the below properties

   cluster.name: production
   node.name: node1
   network.bind_host: 10.0.1.22
   network.host: 0.0.0.0
   transport.tcp.port: 9300
   

2. Add the following in Java Elastic API for Bulk Push (just a code snippet). For IP Address add public IP address of elastic search machine

   Client client;
   BulkRequestBuilder requestBuilder;
   try {
       client = TransportClient.builder().settings(Settings.builder().put("cluster.name", "production").put("node.name","node1")).build().addTransportAddress(
       new InetSocketTransportAddress(InetAddress.getByName(""), 9300));
       requestBuilder = (client).prepareBulk();
   } 
   catch (Exception e) {
   }
   

3. Open the Firewall ports for 9200,9300

Below is an simple logic in java you traverse elements of array twice and if you see any same element you assign zero to it plus you don't touch the index of element you are comparing.

import java.util.*;
class removeDuplicate{
int [] y ;

public removeDuplicate(int[] array){
    y=array;

    for(int b=0;b<y.length;b++){
        int temp = y[b];
        for(int v=0;v<y.length;v++){
            if( b!=v && temp==y[v]){
                y[v]=0;
            }
        }
    }
}

The stack is a portion of memory that can be manipulated via several key assembly language instructions, such as 'pop' (remove and return a value from the stack) and 'push' (push a value to the stack), but also call (call a subroutine - this pushes the address to return to the stack) and return (return from a subroutine - this pops the address off of the stack and jumps to it). It's the region of memory below the stack pointer register, which can be set as needed. The stack is also used for passing arguments to subroutines, and also for preserving the values in registers before calling subroutines.

The heap is a portion of memory that is given to an application by the operating system, typically through a syscall like malloc. On modern OSes this memory is a set of pages that only the calling process has access to.

The size of the stack is determined at runtime, and generally does not grow after the program launches. In a C program, the stack needs to be large enough to hold every variable declared within each function. The heap will grow dynamically as needed, but the OS is ultimately making the call (it will often grow the heap by more than the value requested by malloc, so that at least some future mallocs won't need to go back to the kernel to get more memory. This behavior is often customizable)

Because you've allocated the stack before launching the program, you never need to malloc before you can use the stack, so that's a slight advantage there. In practice, it's very hard to predict what will be fast and what will be slow in modern operating systems that have virtual memory subsystems, because how the pages are implemented and where they are stored is an implementation detail.

For regular React Class based components, refer to React Docs for the forceUpdate api at this URL. The docs mention that:

Normally you should try to avoid all uses of forceUpdate() and only read from this.props and this.state in render()

However, it is also mentioned in the docs that:

If your render() method depends on some other data, you can tell React that the component needs re-rendering by calling forceUpdate().

So, although use cases for using forceUpdate might be rare, and I have not used it ever, however I have seen it used by other developers in some legacy corporate projects that I have worked on.

So, for the equivalent functionality for Functional Components, refer to the React Docs for HOOKS at this URL. Per the above URL, one can use the "useReducer" hook to provide a forceUpdate functionality for Functional Components.

A working code sample that does not use state or props is provided below, which is also available on CodeSandbox at this URL

import React, { useReducer, useRef } from "react";
import ReactDOM from "react-dom";

import "./styles.css";

function App() {
  // Use the useRef hook to store a mutable value inside a functional component for the counter
  let countref = useRef(0);

  const [, forceUpdate] = useReducer(x => x + 1, 0);

  function handleClick() {
    countref.current++;
    console.log("Count = ", countref.current);
    forceUpdate(); // If you comment this out, the date and count in the screen will not be updated
  }

  return (
    <div className="App">
      <h1> {new Date().toLocaleString()} </h1>
      <h2>You clicked {countref.current} times</h2>
      <button
        onClick={() => {
          handleClick();
        }}
      >
        ClickToUpdateDateAndCount
      </button>
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

NOTE: An alternate approach using the useState hook (instead of useReducer) is also available at this URL.

I like to use:

git diff HEAD^

Or if I only want to diff a specific file:

git diff HEAD^ -- /foo/bar/baz.txt

give it float: right and the h1 float:left and put an element with clear:both after them.

You could do this to disable the first button for example:

$('.ui-dialog-buttonpane button:first').attr('disabled', 'disabled');

readLine() returns pointer to local variable, which causes undefined behaviour.

To get around you can:

1. Create variable in caller function and pass its address to readLine()
2. Allocate memory for line using malloc() - in this case line will be persistent
3. Use global variable, although it is generally a bad practice

Two options save vijay.sql

declare
begin
execute immediate 
'CREATE TABLE DMS_POP_WKLY_REFRESH_'||to_char(sysdate,'YYYYMMDD')||' NOLOGGING PARALLEL AS
SELECT wk.*,bbc.distance_km ,NVL(bbc.tactical_broadband_offer,0) tactical_broadband_offer ,
       sel.tactical_select_executive_flag,
       sel.agent_name,
       res.DMS_RESIGN_CAMPAIGN_CODE,
       pclub.tactical_select_flag
FROM   spineowner.pop_wkly_refresh_20100201 wk,
       dms_bb_coverage_102009 bbc,

       DMS_RESIGN_CAMPAIGN_26052009 res,
       DMS_PRIORITY_CLUB pclub
WHERE  wk.mpn = bbc.mpn(+)
AND    wk.mpn = sel.mpn (+)
AND    wk.mpn = res.mpn (+)
AND    wk.mpn = pclub.mpn (+)'
end;
/

The above will generate table names automatically based on sysdate. If you still need to pass as variable, then save vijay.sql as

declare
begin
execute immediate 
'CREATE TABLE DMS_POP_WKLY_REFRESH_'||&1||' NOLOGGING PARALLEL AS

AND    wk.mpn = res.mpn (+)
AND    wk.mpn = pclub.mpn (+)'
end;

    fprintf(stdout, "%02X%s", buf[i],
             ( i + 1 ) % 16 == 0 ? "\r\n" : " " );

}

C++:

        if (format) {

EmEditor should handle this. As their site claims:

EmEditor is now able to open even larger than 248 GB (or 2.1 billion lines) by opening a portion of the file with the new custom bar - Large File Controller. The Large File Controller allows you to specify the beginning point, end point, and range of the file to be opened. It also allows you to stop the opening of the file and monitor the real size of the file and the size of the temporary disk available.

Not free though..

Because the statement defining obj hasn't finished, key1 doesn't exist yet. Consider this solution:

var obj = { key1: "it" };
obj.key2 = obj.key1 + ' ' + 'works!';
// obj.key2 is now 'it works!'

Yes, it's possible, the syntax is curl [protocol://]<host>[:port], for example:

curl example.com:1234

If you're using Bash, you can also use pseudo-device /dev files to open a TCP connection, e.g.:

exec 5<>/dev/tcp/127.0.0.1/1234
echo "send some stuff" >&5
cat <&5 # Receive some stuff.

It could help you. However, if you convert XML to an array you will loose all attributes that might be present, so you cannot go back to XML and get the same XML.

Since no one else said it, the short-cut to compile (build) a C# app in Visual Studio Code (VSCode) is SHIFT+CTRL+B.

If you want to see the build errors (because they don't pop-up by default), the shortcut is SHIFT+CTRL+M.

(I know this question was asking for more than just the build shortcut. But I wanted to answer the question in the title, which wasn't directly answered by other answers/comments.)

UPDATE:

You have wrong capitalization of environment variables in ENV. Correct one is http_proxy. Your example should be:

FROM ubuntu:13.10
ENV http_proxy <HTTP_PROXY>
ENV https_proxy <HTTPS_PROXY>
RUN apt-get update && apt-get upgrade

or

FROM centos
ENV http_proxy <HTTP_PROXY>
ENV https_proxy <HTTPS_PROXY>
RUN yum update 

All variables specified in ENV are prepended to every RUN command. Every RUN command is executed in own container/environment, so it does not inherit variables from previous RUN commands!

Note: There is no need to call docker daemon with proxy for this to work, although if you want to pull images etc. you need to set the proxy for docker deamon too. You can set proxy for daemon in /etc/default/docker in Ubuntu (it does not affect containers setting).

Also, this can happen in case you run your proxy on host (i.e. localhost, 127.0.0.1). Localhost on host differ from localhost in container. In such case, you need to use another IP (like 172.17.42.1) to bind your proxy to or if you bind to 0.0.0.0, you can use 172.17.42.1 instead of 127.0.0.1 for connection from container during docker build.

You can also look for an example here: How to rebuild dockerfile quick by using cache?

typedef void (Dog::*memfun)();
memfun doSomething = &Dog::bark;
....
(pDog->*doSomething)(); // if pDog is a pointer
// (pDog.*doSomething)(); // if pDog is a reference

To display the all details for each news post title ie. "news.id" which is the primary key, you need to use GROUP BY clause for "news.id"

SELECT news.id, users.username, news.title, news.date,
       news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

Alternately,

You can use your own Application class and call from wherever you needs (especially non-activities).

public class App extends Application {

    protected static Context context = null;

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
    }

    public static Context getContext() {
        return context;
    }

}

And register your Application class :

<application android:name="yourpackage.App" ...

Then call :

App.getContext();

Automatic garbage collection is the process of looking at heap memory, identifying which objects are in use and which are not, and deleting the unused objects. An in use object, or a referenced object, means that some part of your program still maintains a pointer to that object. An unused object, or unreferenced object, is no longer referenced by any part of your program. So the memory used by an unreferenced object can be reclaimed.

In a programming language like C, allocating and deallocating memory is a manual process. In Java, process of deallocating memory is handled automatically by the garbage collector. Please check the link for a better understanding. http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/gc01/index.html

I solved this problem by adding another div as a sibling to the scrolling content div. It's height is set to the radius of the curved borders. There will be design issues if you have content that you want nudged to the very bottom, or text you want to flow into this new div, etc,. but for my UI this thin div is no problem.

The real trick is to have the following structure:

<div class="window">
 <div class="title">Some title text</div>
 <div class="content">Main content area</div>
 <div class="footer"></div>
</div>

Important CSS highlights:

• Your CSS would define the content region with a height and overflow to allow the scrollbar(s) to appear.
• The window class gets the same diameter corners as the title and footer
• The drop shadow, if desired, is only given to the window class
• The height of the footer div is the same as the radius of the bottom corners

Here's what that looks like:

The easiest way to do that would be to use the Params plugin, introduced in beta5. It has utility methods to make it easy to access different types of parameters. As always, reading the tests can prove valuable to understand how something is supposed to be used.

Get a single value

To get the value of a named parameter in a controller, you will need to select the appropriate method for the type of parameter you are looking for and pass in the name.

Examples:

$this->params()->fromPost('paramname');   // From POST
$this->params()->fromQuery('paramname');  // From GET
$this->params()->fromRoute('paramname');  // From RouteMatch
$this->params()->fromHeader('paramname'); // From header
$this->params()->fromFiles('paramname');  // From file being uploaded

Default values

All of these methods also support default values that will be returned if no parameter with the given name is found.

Example:

$orderBy = $this->params()->fromQuery('orderby', 'name');

When visiting http://example.com/?orderby=birthdate, $orderBy will have the value birthdate.
When visiting http://example.com/, $orderBy will have the default value name.
 

Get all parameters

To get all parameters of one type, just don't pass in anything and the Params plugin will return an array of values with their names as keys.

Example:

$allGetValues = $this->params()->fromQuery(); // empty method call

When visiting http://example.com/?orderby=birthdate&filter=hasphone $allGetValues will be an array like

array(
    'orderby' => 'birthdate',
    'filter'  => 'hasphone',
);

Not using Params plugin

If you check the source code for the Params plugin, you will see that it's just a thin wrapper around other controllers to allow for more consistent parameter retrieval. If you for some reason want/need to access them directly, you can see in the source code how it's done.

Example:

$this->getRequest()->getRequest('name', 'default');
$this->getEvent()->getRouteMatch()->getParam('name', 'default');

NOTE: You could have used the superglobals $_GET, $_POST etc., but that is discouraged.

This did the job for me including active main dropdowns and the active childrens (thanks to 422):

$(document).ready(function () {
    var url = window.location;
    // Will only work if string in href matches with location
    $('ul.nav a[href="' + url + '"]').parent().addClass('active');

    // Will also work for relative and absolute hrefs
    $('ul.nav a').filter(function () {
        return this.href == url;
    }).parent().addClass('active').parent().parent().addClass('active');
});

You can use pickle

import pickle
dict = {'one': 1, 'two': 2}
file = open('dump.txt', 'wb')
pickle.dump(dict, file)
file.close()

and to read it again

file = open('dump.txt', 'rb')
dict = pickle.load(file)

EDIT: Guess I misread your question, sorry ... but pickle might help all the same. :)

<div> with some proportions

div {
  position: relative;
  width: 100%;
  height: 100%;
}

<img>'s with their own proportions

img {
  position: absolute;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  width: auto; /* to keep proportions */
  height: auto; /* to keep proportions */
  max-width: 100%; /* not to stand out from div */
  max-height: 100%; /* not to stand out from div */
  margin: auto auto 0; /* position to bottom and center */
}

It sounds like you can pick and choose. If you pick float, you may lose 11 digits of precision. If that's acceptable, go for it -- apparently the Linq designers thought this to be a good tradeoff.

However, if your application needs those extra digits, use decimal. Decimal (implemented correctly) is way more accurate than a float anyway -- no messy translation from base 10 to base 2 and back.

Very short,

What is the purpose of DI? With dependency injection, objects don't define their dependencies themselves, the dependencies are injected to them as needed.

How does it benefit ? The objects don't need to know where and how to get their dependencies, which results in loose coupling between objects, which makes them a lot easier to test.

How is it implemented ? Usually a container manages the lifecycle of objects and their dependencies based on a configuration file or annotations.

gene_name = no_headers.iloc[1:,[1]]

This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:

gene_name[x]

you now have a Series object with a single value. You can't hash the Series.

The solution is to create Series from the start.

gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]

Also, where you have orph_dict[gene_name[x]] =+ 1, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1 to increment the counter.

You were close. You can do:

var element = $("#parentDiv").find(".myClassNameOfInterest");

• .find() - http://api.jquery.com/find

Alternatively, you can do:

var element = $(".myClassNameOfInterest", "#parentDiv");

...which sets the context of the jQuery object to the #parentDiv.

EDIT:

Additionally, it may be faster in some browsers if you do div.myClassNameOfInterest instead of just .myClassNameOfInterest.

I do this with javascript (no library) and CSS - the table body scrolls with the page, and the table does not have to be fixed width or height, although each column must have a width. You can also keep sorting functionality.

Basically:

1. In HTML, create container divs to position the table header row and the table body, also create a "mask" div to hide the table body as it scrolls past the header

2. In CSS, convert the table parts to blocks

3. In Javascript, get the table width and match the mask's width... get the height of the page content... measure scroll position... manipulate CSS to set the table header row position and the mask height

Here's the javascript and a jsFiddle DEMO.

// get table width and match the mask width

function setMaskWidth() { 
  if (document.getElementById('mask') !==null) {
    var tableWidth = document.getElementById('theTable').offsetWidth;

    // match elements to the table width
    document.getElementById('mask').style.width = tableWidth + "px";
   }
}

function fixTop() {

  // get height of page content 
  function getScrollY() {
      var y = 0;
      if( typeof ( window.pageYOffset ) == 'number' ) {
        y = window.pageYOffset;
      } else if ( document.body && ( document.body.scrollTop) ) {
        y = document.body.scrollTop;
      } else if ( document.documentElement && ( document.documentElement.scrollTop) ) {
        y = document.documentElement.scrollTop;
      }
      return [y];
  }  

  var y = getScrollY();
  var y = y[0];

  if (document.getElementById('mask') !==null) {
      document.getElementById('mask').style.height = y + "px" ;

      if (document.all && document.querySelector && !document.addEventListener) {
        document.styleSheets[1].rules[0].style.top = y + "px" ;
      } else {
        document.styleSheets[1].cssRules[0].style.top = y + "px" ;
      }
  }

}

window.onscroll = function() {
  setMaskWidth();
  fixTop();
}

It's possible, but you have to add some JVM flags when you start your application.

You have to add remote debug configuration: Edit configuration -> Remote.

Then you'lll find in displayed dialog window parametrs that you have to add to program execution, like:

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005

Then when your application is launched you can attach your debugger. If you want your application to wait until debugger is connected just change suspend flag to y (suspend=y)

Try using if tracked file.

git rm <path to file>
git reset  <path to file>
git checkout <path to file>

I'm "old school" I define efficiency in lowest latency, processor time and memory usage, our nemesis are the bloated libraries. So there is exactly one right way:

    def rotatel(nums):
        back = nums.pop(0)
        nums.append(back)
        return nums

If you want to compare SQL dates, you can try this:

$this->db->select();
$this->db->from('table_name');
$this->db->where(' date_columnname >= date("'.$from.'")');
$this->db->where( 'date_columnname <= date("'.$to.'")');

That worked for me (PHP and MySQL).

--- Update Angular 9 and Rxjs 6 Solution

1. Using unsubscribe at ngDestroy lifecycle of Angular Component

class SampleComponent implements OnInit, OnDestroy {
  private subscriptions: Subscription;
  private sampleObservable$: Observable<any>;

  constructor () {}

  ngOnInit(){
    this.subscriptions = this.sampleObservable$.subscribe( ... );
  }

  ngOnDestroy() {
    this.subscriptions.unsubscribe();
  }
}

2. Using takeUntil in Rxjs

class SampleComponent implements OnInit, OnDestroy {
  private unsubscribe$: new Subject<void>;
  private sampleObservable$: Observable<any>;

  constructor () {}

  ngOnInit(){
    this.subscriptions = this.sampleObservable$
    .pipe(takeUntil(this.unsubscribe$))
    .subscribe( ... );
  }

  ngOnDestroy() {
    this.unsubscribe$.next();
    this.unsubscribe$.complete();
  }
}

3. for some action that you call at ngOnInit that just happen only one time when component init.

class SampleComponent implements OnInit {

  private sampleObservable$: Observable<any>;

  constructor () {}

  ngOnInit(){
    this.subscriptions = this.sampleObservable$
    .pipe(take(1))
    .subscribe( ... );
  }
}

We also have async pipe. But, this one use on the template (not in Angular component).

The Chrome setting you refer to is to disable the same origin policy.

This was covered in this thread also: Disable firefox same origin policy

about:config -> security.fileuri.strict_origin_policy -> false

Let's say we need to find count of multiple words in a file testfile. There are two ways to go about it

1) Use grep command with regex matching pattern

grep -c '\<\(DOG\|CAT\)\>' testfile

2) Use egrep command

egrep -c 'DOG|CAT' testfile 

With egrep you need not to worry about expression and just separate words by a pipe separator.

You could use coalesce:

insert into destination select coalesce(field1,'somedata'),... from source;

If your command is available in cmd.exe (something like python ./script.py, but not PowerShell command like ii . (this means to open the current directory by Windows Explorer)), you can run cmd.exe within PowerShell. The syntax is like this:

cmd /c "command1 && command2"

Here, && is provided by cmd syntax described in this question.

Well I'm sure that this is the simplest way to populate JTable from ResultSet, without any external library. I have included comments in this method.

public void resultSetToTableModel(ResultSet rs, JTable table) throws SQLException{
        //Create new table model
        DefaultTableModel tableModel = new DefaultTableModel();

        //Retrieve meta data from ResultSet
        ResultSetMetaData metaData = rs.getMetaData();

        //Get number of columns from meta data
        int columnCount = metaData.getColumnCount();

        //Get all column names from meta data and add columns to table model
        for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++){
            tableModel.addColumn(metaData.getColumnLabel(columnIndex));
        }

        //Create array of Objects with size of column count from meta data
        Object[] row = new Object[columnCount];

        //Scroll through result set
        while (rs.next()){
            //Get object from column with specific index of result set to array of objects
            for (int i = 0; i < columnCount; i++){
                row[i] = rs.getObject(i+1);
            }
            //Now add row to table model with that array of objects as an argument
            tableModel.addRow(row);
        }

        //Now add that table model to your table and you are done :D
        table.setModel(tableModel);
    }

Please use regex to remove anything before |

example

dsfdf | fdfsfsf
dsdss|gfghhghg
dsdsds |dfdsfsds

Use find and replace in notepad++

find: .+(\|) replace: \1

output

| fdfsfsf
|gfghhghg
|dfdsfsds

I've had success using this in response to a button click, so I guess that you can use it too after updating your contents:

myListView.smoothScrollToPosition(theListAdapter.getCount() -1);

you can make a jQuery onChange event to get the text from the combobox when the user select one of them:

<script>    
     $( "select" )
     .change(function () {
     var str = "";
     $( "select option:selected" ).each(function() {
     str += $( this ).text() + " ";
     });
     $('#EvaluationName').val(str);
     })
     .change();
 </script>

When you select an option, it will save the text in an Input hidde

  <input type="hidden" id="EvaluationName" name="EvaluationName" value="<?= $Evaluation ?>" />

After that, when you submit the form, just catch up the value of the input

$Evaluation = $_REQUEST['EvaluationName'];

Then you can do wathever you want with the text, for instance save it in a session variable and send it to other page. etc.

Actually, you don't need to modify the object prototype. The following should work to 'obtain' unique ids for any object, efficiently enough.

var __next_objid=1;
function objectId(obj) {
    if (obj==null) return null;
    if (obj.__obj_id==null) obj.__obj_id=__next_objid++;
    return obj.__obj_id;
}

const date = moment(YOUR_DATE)
return (moment().diff(date, 'days') >= 2) ? date.fromNow() : date.calendar().split(' ')[0]

here is the example which i used to retrive and parse json data from s3.

    var params = {Bucket: BUCKET_NAME, Key: KEY_NAME};
    new AWS.S3().getObject(params, function(err, json_data)
    {
      if (!err) {
        var json = JSON.parse(new Buffer(json_data.Body).toString("utf8"));

       // PROCESS JSON DATA
           ......
     }
   });

You can pass lists just like other types:

l = [1,2,3]

def stuff(a):
   for x in a:
      print a


stuff(l)

This prints the list l. Keep in mind lists are passed as references not as a deep copy.

Yet another full outer join

As was not that happy with the simplicity and the readability of the other propositions, I ended up with this :

It does not have the pretension to be fast ( about 800 ms to join 1000 * 1000 on a 2020m CPU : 2.4ghz / 2cores). To me, it is just a compact and casual full outer join.

It works the same as a SQL FULL OUTER JOIN (duplicates conservation)

Cheers ;-)

        });

        return result;

The idea is to

1. Build Ids based on provided key function builders
2. Process left only items
3. Process inner join
4. Process right only items

For the next person Googling this topic, I've written a small NPM package to make it simple to generate Google Calendar URLs. It includes TypeScript type definitions, for those who need that. Hope it helps!

I tried some above and below but they didn't work. This worked for me:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.navigationBar.topItem?.title = ""
}

If you don't want to group, then use the following method:

db.collection.aggregate( [ { $match : { score : { $gt : 70, $lte : 90 } } }, { $count: 'count' } ] );

You can you use GentleRequest, which is lightweight library for making http requests(DISCLAIMER: I am the author):

Connections connections = new HttpConnections();
Binary binary = new PacketsBinary(new 
BufferedInputStream(new FileInputStream(file)), 
   file.length());
//Content-Type is set to multipart/form-data; boundary= 
//{generated by multipart object}
MultipartForm multipart = new HttpMultipartForm(
    new HttpFormPart("user", "aplication/json", 
       new JSONObject().toString().getBytes()),
    new HttpFormPart("java", "java.png", "image/png", 
       binary.content()));
Response response = connections.response(new 
    PostRequest(url, multipart));
if (response.hasSuccessCode()) {
    byte[] raw = response.body().value();
    String string = response.body().stringValue();
    JSONOBject json = response.body().jsonValue();
 } else {

 }

I use it and I'm happy with it, as I have to type much less to make a new header. It worked fine for me in three platforms: Windows, Mac and Linux.

I don't have any performance information but I believe that the difference between #pragma and the include guard will be nothing comparing to the slowness of parsing the C++ grammar. That's the real problem. Try to compile the same number of files and lines with a C# compiler for example, to see the difference.

In the end, using the guard or the pragma, won't matter at all.

You can look at the query cache: http://www.databasejournal.com/features/mysql/article.php/3110171/MySQLs-Query-Cache.htm but it might not give you access to the actual queries and will be very hit-and-miss if it did work (subtle pun intended)

But MySQL Query Browser very likely maintains its own list of queries that it runs, outside of the MySQL engine. You would have to do the same in your app.

Edit: see dan m's comment leading to this: How to show the last queries executed on MySQL? looks sound.

If you want to send your data inside the body, then you have to make a POST or PUT instead of GET.

For me, it looks like you're trying to send the query with uri parameters, which is not related to GET, you can also put these parameters on POST, PUT and so on.

The query is an optional part, separated by a question mark ("?"), that contains additional identification information that is not hierarchical in nature. The query string syntax is not generically defined, but it is commonly organized as a sequence of = pairs, with the pairs separated by a semicolon or an ampersand.

For example:

curl http://server:5050/a/c/getName?param0=foo&param1=bar

A bit late to the party but you can also use a context manager, if you're opening and closing your file multiple times, or logging data, statistics, etc.

from contextlib import contextmanager
import pandas as pd
@contextmanager
def open_file(path, mode):
     file_to=open(path,mode)
     yield file_to
     file_to.close()


##later
saved_df=pd.DataFrame(data)
with open_file('yourcsv.csv','r') as infile:
      saved_df.to_csv('yourcsv.csv',mode='a',header=False)`

I found this PostgreSQL documentation helpful: http://www.postgresql.org/docs/8.0/interactive/functions-conditional.html.

In my case, I sought plain SQL to concatenate a field with brackets around it, if the field is not empty.

select itemid, 
  CASE 
    itemdescription WHEN '' THEN itemname 
    ELSE itemname || ' (' || itemdescription || ')' 
  END 
from items;

get-windowsfeature | where name -like RSAT-AD-PowerShell | Install-WindowsFeature

If your project is Maven-based, remember to set scope to provided for such dependencies as servlet-api, jsp-api. Otherwise, these jars will be exported to WEB-INF/lib and hence contaminate with those in Tomcat server. That causes painful problems.

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
  <scope>provided</scope>
</dependency>
<dependency>
  <groupId>javax.servlet.jsp</groupId>
  <artifactId>jsp-api</artifactId>
  <version>2.1</version>
  <scope>provided</scope>
</dependency>

To generalize the comment from @sth. Item deletion in any class, that implements abc.MutableSequence, and in list in particular, is done via __delitem__ magic method. This method works similar to __getitem__, meaning it can accept either an integer or a slice. Here is an example:

class MyList(list):
    def __delitem__(self, item):
        if isinstance(item, slice):
            for i in range(*item.indices(len(self))):
                self[i] = 'null'
        else:
            self[item] = 'null'


l = MyList(range(10))
print(l)
del l[5:8]
print(l)

This will output

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[0, 1, 2, 3, 4, 'null', 'null', 'null', 8, 9]

$("#bchange").click(function() {
    $("body, this").css("background-color","yellow");
});

I would suggest to end java.exe or javaw.exe process from task manager and try again. This will not end the entire eclipse application but will free the port.

1. It is a class in org.openqa.selenium.remote.DesiredCapabilities package.
2. It gives facility to set the properties of browser. Such as to set BrowserName, Platform, Version of Browser.
3. Mostly DesiredCapabilities class used when do we used Selenium Grid.
4. We have to execute mutiple TestCases on multiple Systems with different browser with Different version and Different Operating System.

Example:

WebDriver driver;
String baseUrl , nodeUrl;
baseUrl = "https://www.facebook.com";
nodeUrl = "http://192.168.10.21:5568/wd/hub";

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setBrowserName("firefox");
capability.setPlatform(Platform.WIN8_1);

driver = new RemoteWebDriver(new URL(nodeUrl),capability);
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES);

One more way is to extend the application (as my application was to inherit and customize the parent). It invokes the parent and its commandlinerunner automatically.

@SpringBootApplication
public class ChildApplication extends ParentApplication{
    public static void main(String[] args) {
        SpringApplication.run(ChildApplication.class, args);
    }
}

• getattr(x, 'y') is equivalent to x.y
• setattr(x, 'y', v) is equivalent to x.y = v
• delattr(x, 'y') is equivalent to del x.y

try to run

sudo su - postgres
psql
ALTER ROLE 'dbname'

In response to the other question which was marked as duplicate (see here) I figured out a quick and easy solution based on the answer of Soren:

data.Tasks.AddRange(
    data.Task.AsEnumerable().Select(t => new Task{
        creator_id   = t.ID,
        start_date   = t.Incident.DateOpened,
        end_date     = t.Incident.DateCLosed,
        product_code = t.Incident.ProductCode
        // so on...
    })
);
data.SaveChanges();

Note: This solution only works if you have a navigation property (foreign key) on the Task class (here called 'Incident'). If you don't have that, you can just use one of the other posted solutions with "AsQueryable()".

Alternatively, this solution works with both Apache2 version < 2.4 as well as >= 2.4. Make sure that the "version" module is enabled:

a2enmod version

And then use this code instead:

<IfVersion < 2.4>
    Allow from all
</IfVersion>
<IfVersion >= 2.4>
    Require all granted
</IfVersion>

If you can have an empty config/database.yml file then define ENV['DATABASE_URL'] variable, then It will work

$ cat config/database.yml
 
$ echo $DATABASE_URL
mysql://root:[email protected]:3306/my_db_name

for Heroku: heroku config:set DATABASE_URL='mysql://root:[email protected]/my_db_name'

You can use points for the overplot, that is.

plot(x1, y1,col='red')

points(x2,y2,col='blue')

Your problem is with this line:

number4 = list(cow[n])

It tries to take cow[n], which returns an integer, and make it a list. This doesn't work, as demonstrated below:

>>> a = 1
>>> list(a)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>>

Perhaps you meant to put cow[n] inside a list:

number4 = [cow[n]]

See a demonstration below:

>>> a = 1
>>> [a]
[1]
>>>

Also, I wanted to address two things:

1. Your while-statement is missing a : at the end.
2. It is considered very dangerous to use input like that, since it evaluates its input as real Python code. It would be better here to use raw_input and then convert the input to an integer with int.

To split up the digits and then add them like you want, I would first make the number a string. Then, since strings are iterable, you can use sum:

>>> a = 137
>>> a = str(a)
>>> # This way is more common and preferred
>>> sum(int(x) for x in a)
11
>>> # But this also works
>>> sum(map(int, a))
11
>>>

You need to do next in command line:

wsimport -keep -s (name of folder where you want to store generated code) urlToWsdl

for example:

wsimport -keep -s C://NewFolder https://www.blablabla.com

Behaviour

Suppose you have two lists:

Id  Value
1   A
2   B
3   C

Id  ChildValue
1   a1
1   a2
1   a3
2   b1
2   b2

When you Join the two lists on the Id field the result will be:

Value ChildValue
A     a1
A     a2
A     a3
B     b1
B     b2

When you GroupJoin the two lists on the Id field the result will be:

Value  ChildValues
A      [a1, a2, a3]
B      [b1, b2]
C      []

So Join produces a flat (tabular) result of parent and child values.
GroupJoin produces a list of entries in the first list, each with a group of joined entries in the second list.

That's why Join is the equivalent of INNER JOIN in SQL: there are no entries for C. While GroupJoin is the equivalent of OUTER JOIN: C is in the result set, but with an empty list of related entries (in an SQL result set there would be a row C - null).

Syntax

So let the two lists be IEnumerable<Parent> and IEnumerable<Child> respectively. (In case of Linq to Entities: IQueryable<T>).

Join syntax would be

from p in Parent
join c in Child on p.Id equals c.Id
select new { p.Value, c.ChildValue }

returning an IEnumerable<X> where X is an anonymous type with two properties, Value and ChildValue. This query syntax uses the Join method under the hood.

GroupJoin syntax would be

from p in Parent
join c in Child on p.Id equals c.Id into g
select new { Parent = p, Children = g }

returning an IEnumerable<Y> where Y is an anonymous type consisting of one property of type Parent and a property of type IEnumerable<Child>. This query syntax uses the GroupJoin method under the hood.

We could just do select g in the latter query, which would select an IEnumerable<IEnumerable<Child>>, say a list of lists. In many cases the select with the parent included is more useful.

Some use cases

1. Producing a flat outer join.

As said, the statement ...

from p in Parent
join c in Child on p.Id equals c.Id into g
select new { Parent = p, Children = g }

... produces a list of parents with child groups. This can be turned into a flat list of parent-child pairs by two small additions:

from p in parents
join c in children on p.Id equals c.Id into g // <= into
from c in g.DefaultIfEmpty()               // <= flattens the groups
select new { Parent = p.Value, Child = c?.ChildValue }

The result is similar to

Value Child
A     a1
A     a2
A     a3
B     b1
B     b2
C     (null)

Note that the range variable c is reused in the above statement. Doing this, any join statement can simply be converted to an outer join by adding the equivalent of into g from c in g.DefaultIfEmpty() to an existing join statement.

This is where query (or comprehensive) syntax shines. Method (or fluent) syntax shows what really happens, but it's hard to write:

parents.GroupJoin(children, p => p.Id, c => c.Id, (p, c) => new { p, c })
       .SelectMany(x => x.c.DefaultIfEmpty(), (x,c) => new { x.p.Value, c?.ChildValue } )

So a flat outer join in LINQ is a GroupJoin, flattened by SelectMany.

2. Preserving order

Suppose the list of parents is a bit longer. Some UI produces a list of selected parents as Id values in a fixed order. Let's use:

var ids = new[] { 3,7,2,4 };

Now the selected parents must be filtered from the parents list in this exact order.

If we do ...

var result = parents.Where(p => ids.Contains(p.Id));

... the order of parents will determine the result. If the parents are ordered by Id, the result will be parents 2, 3, 4, 7. Not good. However, we can also use join to filter the list. And by using ids as first list, the order will be preserved:

from id in ids
join p in parents on id equals p.Id
select p

The result is parents 3, 7, 2, 4.

For those that haven't found a working solution above, I believe I have a working one. My specific use case was that I wanted to scroll to the bottom of a specific div - in my case a chatbox - whenever a new message was added to the array.

const container = this.$el.querySelector('#messagesCardContent');
        this.$nextTick(() => {
          // DOM updated
          container.scrollTop = container.scrollHeight;
        });

I have to use nextTick as we need to wait for the dom to update from the data change before doing the scroll!

I just put the above code in a watcher for the messages array, like so:

messages: {
      handler() {
        // this scrolls the messages to the bottom on loading data
        const container = this.$el.querySelector('#messagesCard');
        this.$nextTick(() => {
          // DOM updated
          container.scrollTop = container.scrollHeight;
        });
      },
      deep: true,
    }, 

We can read properties file in spring boot using 3 way

1. Read value from application.properties Using @Value

map key as

public class EmailService {

 @Value("${email.username}")
 private String username;

}

2. Read value from application.properties Using @ConfigurationProperties

In this we will map prefix of key using ConfigurationProperties and key name is same as field of class

  @Component
   @ConfigurationProperties("email")
    public class EmailConfig {

        private String   username;
    }

3. Read application.properties Using using Environment object

public class EmailController {

@Autowired
private Environment env;

@GetMapping("/sendmail")
public void sendMail(){     
    System.out.println("reading value from application properties file  using Environment ");
    System.out.println("username ="+ env.getProperty("email.username"));
    System.out.println("pwd ="+ env.getProperty("email.pwd"));
}

The full list of readyState values is:

State  Description
0      The request is not initialized
1      The request has been set up
2      The request has been sent
3      The request is in process
4      The request is complete

(from https://www.w3schools.com/js/js_ajax_http_response.asp)

In practice you almost never use any of them except for 4.

Some XMLHttpRequest implementations may let you see partially received responses in responseText when readyState==3, but this isn't universally supported and shouldn't be relied upon.

("Jesse" or "jesse")

The above expression tests whether or not "Jesse" evaluates to True. If it does, then the expression will return it; otherwise, it will return "jesse". The expression is equivalent to writing:

"Jesse" if "Jesse" else "jesse"

Because "Jesse" is a non-empty string though, it will always evaluate to True and thus be returned:

>>> bool("Jesse")  # Non-empty strings evaluate to True in Python
True
>>> bool("")  # Empty strings evaluate to False
False
>>>
>>> ("Jesse" or "jesse")
'Jesse'
>>> ("" or "jesse")
'jesse'
>>>

This means that the expression:

name == ("Jesse" or "jesse")

is basically equivalent to writing this:

name == "Jesse"

In order to fix your problem, you can use the in operator:

# Test whether the value of name can be found in the tuple ("Jesse", "jesse")
if name in ("Jesse", "jesse"):

Or, you can lowercase the value of name with str.lower and then compare it to "jesse" directly:

# This will also handle inputs such as "JeSSe", "jESSE", "JESSE", etc.
if name.lower() == "jesse":

First of all: Don't put secrets in clear text unless you know why it is a safe thing to do (i.e. you have assessed what damage can be done by an attacker knowing the secret).

If you are ok with putting secrets in your script, you could ship an ssh key with it and execute in an ssh-agent shell:

#!/usr/bin/env ssh-agent /usr/bin/env bash
KEYFILE=`mktemp`
cat << EOF > ${KEYFILE}
-----BEGIN RSA PRIVATE KEY-----
[.......]
EOF
ssh-add ${KEYFILE}

# do your ssh things here...

# Remove the key file.
rm -f ${KEYFILE}

A benefit of using ssh keys is that you can easily use forced commands to limit what the keyholder can do on the server.

A more secure approach would be to let the script run ssh-keygen -f ~/.ssh/my-script-key to create a private key specific for this purpose, but then you would also need a routine for adding the public key to the server.

in an actual SQL query, you just add a newline

INSERT INTO table (text) VALUES ('hi this is some text
and this is a linefeed.
and another');

String is a class in Java different from other programming languages. So as for every class the object declaration and initialization is

String st1 = new String();

or

String st2 = new String("Hello"); 
String st3 = new String("Hello");

Here, st1, st2 and st3 are different objects.

That is:

st1 == st2 // false
st1 == st3 // false
st2 == st3 // false

Because st1, st2, st3 are referencing 3 different objects, and == checks for the equality in memory location, hence the result.

But:

st1.equals(st2) // false
st2.equals(st3) // true

Here .equals() method checks for the content, and the content of st1 = "", st2 = "hello" and st3 = "hello". Hence the result.

And in the case of the String declaration

String st = "hello";

Here, intern() method of String class is called, and checks if "hello" is in intern pool, and if not, it is added to intern pool, and if "hello" exist in intern pool, then st will point to the memory of the existing "hello".

So in case of:

String st3 = "hello";
String st4 = "hello"; 

Here:

st3 == st4 // true

Because st3 and st4 pointing to same memory address.

Also:

st3.equals(st4);  // true as usual

The algorithm you are using, "AES", is a shorthand for "AES/ECB/NoPadding". What this means is that you are using the AES algorithm with 128-bit key size and block size, with the ECB mode of operation and no padding.

In other words: you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception.

If you want to encrypt data in sizes that are not multiple of 16 bytes, you are either going to have to use some kind of padding, or a cipher-stream. For instance, you could use CBC mode (a mode of operation that effectively transforms a block cipher into a stream cipher) by specifying "AES/CBC/NoPadding" as the algorithm, or PKCS5 padding by specifying "AES/ECB/PKCS5", which will automatically add some bytes at the end of your data in a very specific format to make the size of the ciphertext multiple of 16 bytes, and in a way that the decryption algorithm will understand that it has to ignore some data.

In any case, I strongly suggest that you stop right now what you are doing and go study some very introductory material on cryptography. For instance, check Crypto I on Coursera. You should understand very well the implications of choosing one mode or another, what are their strengths and, most importantly, their weaknesses. Without this knowledge, it is very easy to build systems which are very easy to break.

Update: based on your comments on the question, don't ever encrypt passwords when storing them at a database!!!!! You should never, ever do this. You must HASH the passwords, properly salted, which is completely different from encrypting. Really, please, don't do what you are trying to do... By encrypting the passwords, they can be decrypted. What this means is that you, as the database manager and who knows the secret key, you will be able to read every password stored in your database. Either you knew this and are doing something very, very bad, or you didn't know this, and should get shocked and stop it.

You can also try ternary operator. Something like this

{{data.id === 5 ? "it's true" : "it's false"}}

Change your html code little bit and try this hope so it will be work for you.

Offering an interactive sort handling multiple columns is nothing trivial.

Unless you want to write a good amount of code handling logic for multiple row clicks, editing and refreshing page content, managing sort algorithms for large tables… then you really are better off adopting a plug-in.

tablesorter, (with updates by Mottie) is my favorite. It’s easy to get going and very customizable. Just add the class tablesorter to the table you want to sort, then invoke the tablesorter plugin in a document load event:

$(function(){
    $("#myTable").tablesorter();
});

You can browse the documentation to learn about advanced features.

Altough the question is for HTML, I would also additionally like to give info about how to auto-format your Javascript code for Sublime Text 2;

You can select all your code(ctrl + A) and use the in-app functionality, reindent(Edit -> Line -> Reindent) or you can use JsFormat formatting plugin for Sublime Text 2 if you would like to have more customizable settings on how to format your code to addition to the Sublime Text's default tab/indent settings.

https://github.com/jdc0589/JsFormat

You can easily install JsFormat with using Package Control (Preferences -> Package Control) Open package control then type install, hit enter. Then type js format and hit enter, you're done. (The package controller will show the status of the installation with success and errors on the bottom left bar of Sublime)

Add the following line to your key bindings (Preferences -> Key Bindings User)

{ "keys": ["ctrl+alt+2"], "command": "js_format"}

I'm using ctrl + alt + 2, you can change this shortcut key whatever you want to. So far, JsFormat is a good plugin, worth to try it!

Hope this will help someone.

The following CSS based solution works for me:

<html>
 <head>
  <style type='text/css'>
   textarea {
    white-space: nowrap;
    overflow:    scroll;
    overflow-y:  hidden;
    overflow-x:  scroll;
    overflow:    -moz-scrollbars-horizontal;
   }
  </style>
 </head>
 <body>
  <form>
   <textarea>This is a long line of text for testing purposes...</textarea>
  </form>
 </body>
</html>

You can specify USER in the Dockerfile. All subsequent actions will be performed using that account. You can specify USER one line before the CMD or ENTRYPOINT if you only want to use that user when launching a container (and not when building the image). When you start a container from the resulting image, you will attach as the specified user.

         }; 
     }
 }  
setTimeout(function(){count = 1;},200);

The shortest way is by adding the ObsoleteAttribute as an attribute to the method. Make sure to include an appropriate explanation:

[Obsolete("Method1 is deprecated, please use Method2 instead.")]
public void Method1()
{ … }

You can also cause the compilation to fail, treating the usage of the method as an error instead of warning, if the method is called from somewhere in code like this:

[Obsolete("Method1 is deprecated, please use Method2 instead.", true)]

A global variable would be best expressed in an external JavaScript file:

var system_status;

Make sure that this has not been used anywhere else. Then to access the variable on your page, just reference it as such. Say, for example, you wanted to fill in the results on a textbox,

document.getElementById("textbox1").value = system_status;

To ensure that the object exists, use the document ready feature of jQuery.

Example:

$(function() {
    $("#textbox1")[0].value = system_status;
});

<style name="progressColor" parent="Widget.AppCompat.ProgressBar">
    <item name="colorControlActivated">@color/colorPrimary</item>
</style>


<ProgressBar
    android:id="@+id/progressBar"
    android:layout_width="250dp"
    android:theme="@style/progressColor"
    android:layout_height="250dp"
    android:layout_centerInParent="true" />

The <figcaption> tag in HTML5 allows you to enter text to your image for example:

<figcaption>
Your text here
</figcaption>.

You can then use CSS to position the text where it should be on the image.

If you want to set this up once and use it everywhere, just configure your own middleware. When you are setting up your app, use the following to define a new function on the response object:

app.use((req, res, next) => {
  res.show = (name) => {
    res.sendFile(`/public/${name}`, {root: __dirname});
  };
  next();
});

Then use it as follows:

app.get('/demo', (req, res) => {
  res.show("index1.html");
});

If you even did not get scroll after doing what is written above .....

Set the android:layout_height="250dp"or you can say xdp where x can be any numerical value.

Why not this:

CREATE PROCEDURE SP_Reporting(IN tablename VARCHAR(20))
BEGIN
     IF tablename IS NOT NULL THEN
          #proceed the code
     END IF;
     # Do nothing otherwise
END;

(set-face-attribute 'default nil :height 100)

The value is in 1/10pt, so 100 will give you 10pt, etc.

It happened to me before.

When the table has been created and I added in .HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity) later, the code migration somehow could not assign default value for the Guid column.

The fix:

All we need is to go to the database, select the Id column and add newsequentialid() manually into Default Value or Binding.

No need to update dbo.__MigrationHistory table.

Hope it helps.

The solution of adding New Guid() is generally not preferred, because in theory there is possibility that you might get a duplicate accidentally.

And you shouldn't worry about directly editing in the database. All Entity Framework do is automate part of our database work.

Translating

.HasDatabaseGeneratedOption(DatabaseGeneratedOption.Identity)

into

[Id] [uniqueidentifier] NOT NULL DEFAULT newsequentialid(),

If somehow our EF missed one thing and did not add in the default value for us, just go ahead and add it manually.

Insert query doesn't support where keyword*

Conditions apply because you can use where condition for sub-select statements. You can perform complicated inserts using sub-selects.

For example:

INSERT INTO suppliers
(supplier_id, supplier_name)
SELECT account_no, name
FROM customers
WHERE city = 'Newark';

By placing a "select" in the insert statement, you can perform multiples inserts quickly.

With this type of insert, you may wish to check for the number of rows being inserted. You can determine the number of rows that will be inserted by running the following SQL statement before performing the insert.

SELECT count(*)
FROM customers
WHERE city = 'Newark';

You can make sure that you do not insert duplicate information by using the EXISTS condition.

For example, if you had a table named clients with a primary key of client_id, you could use the following statement:

INSERT INTO clients
(client_id, client_name, client_type)
SELECT supplier_id, supplier_name, 'advertising'
FROM suppliers
WHERE not exists (select * from clients
where clients.client_id = suppliers.supplier_id);

This statement inserts multiple records with a subselect.

If you wanted to insert a single record, you could use the following statement:

INSERT INTO clients
(client_id, client_name, client_type)
SELECT 10345, 'IBM', 'advertising'
FROM dual
WHERE not exists (select * from clients
where clients.client_id = 10345);

The use of the dual table allows you to enter your values in a select statement, even though the values are not currently stored in a table.

you have to create a custom DataGridView

`

namespace System.Windows.Forms
{
    class MyDataGridView : DataGridView
    {
        public bool PreventUserClick = false;

        public MyDataGridView()
        {

        }
        protected override void OnMouseDown(MouseEventArgs e)
        {
            if (PreventUserClick) return;

            base.OnMouseDown(e);
        }
    }
}

` note that you have to first compile the program once with the added class, before you can use the new control.

then go to The .Designer.cs and change the old DataGridView to the new one without having to mess up you previous code.

private System.Windows.Forms.DataGridView dgv; // found close to the bottom

…

private void InitializeComponent() {
    ...
    this.dgv = new System.Windows.Forms.DataGridView();
    ...
}

to (respective)

private System.Windows.Forms.MyDataGridView dgv;

this.dgv = new System.Windows.Forms.MyDataGridView();

I just created a CodePen that shows how this can be done pretty easily using ES6.

http://codepen.io/travist/pen/GWRBQV

Basically, here is the class that does this.

let getPropertyValue = function(style, prop) {
  let value = style.getPropertyValue(prop);
  value = value ? value.replace(/[^0-9.]/g, '') : '0';
  return parseFloat(value);
}

let getElementRect = function(element) {
  let style = window.getComputedStyle(element, null);
  return {
    x: getPropertyValue(style, 'left'),
    y: getPropertyValue(style, 'top'),
    width: getPropertyValue(style, 'width'),
    height: getPropertyValue(style, 'height')
  }
}

To conditionally check the length of the string, use CASE.

SELECT  CASE WHEN LEN(comments) <= 60 
             THEN comments
             ELSE LEFT(comments, 60) + '...'
        END  As Comments
