Programs & Examples On #Multi upload

Using this source code you can upload multiple file like google one by one through ajax. Also you can see the uploading progress

HTML

 <input type="file" id="multiupload" name="uploadFiledd[]" multiple >
 <button type="button" id="upcvr" class="btn btn-primary">Start Upload</button>
 <div id="uploadsts"></div>

Javascript

    <script>

    function uploadajax(ttl,cl){

    var fileList = $('#multiupload').prop("files");
    $('#prog'+cl).removeClass('loading-prep').addClass('upload-image');

    var form_data =  "";

    form_data = new FormData();
    form_data.append("upload_image", fileList[cl]);


    var request = $.ajax({
              url: "upload.php",
              cache: false,
              contentType: false,
              processData: false,
              async: true,
              data: form_data,
              type: 'POST', 
              xhr: function() {  
                  var xhr = $.ajaxSettings.xhr();
                  if(xhr.upload){ 
                  xhr.upload.addEventListener('progress', function(event){
                      var percent = 0;
                      if (event.lengthComputable) {
                          percent = Math.ceil(event.loaded / event.total * 100);
                      }
                      $('#prog'+cl).text(percent+'%') 
                   }, false);
                 }
                 return xhr;
              },
              success: function (res, status) {
                  if (status == 'success') {
                      percent = 0;
                      $('#prog' + cl).text('');
                      $('#prog' + cl).text('--Success: ');
                      if (cl < ttl) {
                          uploadajax(ttl, cl + 1);
                      } else {
                          alert('Done');
                      }
                  }
              },
              fail: function (res) {
                  alert('Failed');
              }    
          })
    }

    $('#upcvr').click(function(){
        var fileList = $('#multiupload').prop("files");
        $('#uploadsts').html('');
        var i;
        for ( i = 0; i < fileList.length; i++) {
            $('#uploadsts').append('<p class="upload-page">'+fileList[i].name+'<span class="loading-prep" id="prog'+i+'"></span></p>');
            if(i == fileList.length-1){
                uploadajax(fileList.length-1,0);
            }
         }
    });
    </script>

PHP

upload.php
    move_uploaded_file($_FILES["upload_image"]["tmp_name"],$_FILES["upload_image"]["name"]);

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

I find the most valuable feature of .FormulaR1C1 is sheer speed. Versus eg a couple of very large loops filling some data into a sheet, If you can convert what you are doing into a .FormulaR1C1 form. Then a single operation eg myrange.FormulaR1C1 = "my particular formuala" is blindingly fast (can be a thousand times faster). No looping and counting - just fill the range at high speed.

pip install -U pip
pip install -U cython

Information provided by @Gord

As of September 2019 pywin32 is now available from PyPI and installs the latest version (currently version 224). This is done via the pip command

pip install pywin32

If you wish to get an older version the sourceforge link below would probably have the desired version, if not you can use the command, where xxx is the version you require, e.g. 224

pip install pywin32==xxx

This differs to the pip command below as that one uses pypiwin32 which currently installs an older (namely 223)

Browsing the docs I see no reason for these commands to work for all python3.x versions, I am unsure on python2.7 and below so you would have to try them and if they do not work then the solutions below will work.

Probably now undesirable solutions but certainly still valid as of September 2019

There is no version of specific version ofwin32api. You have to get the pywin32module which currently cannot be installed via pip. It is only available from this link at the moment.

https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/

The install does not take long and it pretty much all done for you. Just make sure to get the right version of it depending on your python version :)

EDIT

Since I posted my answer there are other alternatives to downloading the win32api module.

It is now available to download through pip using this command;

pip install pypiwin32

Also it can be installed from this GitHub repository as provided in comments by @Heath

Create a group object and call methods like below example:

grp = df.groupby(['col1',  'col2',  'col3']) 

grp.max() 
grp.mean() 
grp.describe() 

At the beginning of your main method, add this line of code :

final long startTime = System.nanoTime();

And then, at the last line of your main method, you can add :

final long duration = System.nanoTime() - startTime;

duration now contains the time in nanoseconds that your program ran. You can for example print this value like this:

System.out.println(duration);

If you want to show duration time in seconds, you must divide the value by 1'000'000'000. Or if you want a Date object: Date myTime = new Date(duration / 1000); You can then access the various methods of Date to print number of minutes, hours, etc.

If you only want to add Datapoints above the bars, you could easily do it with:

 for i in range(len(frequencies)): # your number of bars
    plt.text(x = x_values[i]-0.25, #takes your x values as horizontal positioning argument 
    y = y_values[i]+1, #takes your y values as vertical positioning argument 
    s = data_labels[i], # the labels you want to add to the data
    size = 9) # font size of datalabels

You need to change your code as below:

<html>
<body>

<span id="span_Id">Click the button to display the content.</span>

<button onclick="displayDate()">Click Me</button>

<script>
function displayDate() {
   var span_Text = document.getElementById("span_Id").innerText;
   alert (span_Text);
}
</script>
</body>
</html>

You can loop through the object:

var test = {
  test1: null,
  test2: 'somestring',
  test3: 3,
}

function clean(obj) {
  for (var propName in obj) {
    if (obj[propName] === null || obj[propName] === undefined) {
      delete obj[propName];
    }
  }
  return obj
}

console.log(test);
console.log(clean(test));

If you're concerned about this property removal not running up object's proptype chain, you can also:

function clean(obj) {
  var propNames = Object.getOwnPropertyNames(obj);
  for (var i = 0; i < propNames.length; i++) {
    var propName = propNames[i];
    if (obj[propName] === null || obj[propName] === undefined) {
      delete obj[propName];
    }
  }
}

A few notes on null vs undefined:

test.test1 === null; // true
test.test1 == null; // true

test.notaprop === null; // false
test.notaprop == null; // true

test.notaprop === undefined; // true
test.notaprop == undefined; // true

Well, setTimeout is better in one situation, as I have just learned. I always use setInterval, which i have left to run in the background for more than half an hour. When i switched back to that tab, the slideshow (on which the code was used) was changing very rapidly, instead of every 5 seconds that it should have. It does in fact happen again as i test it more and whether it's the browser's fault or not isn't important, because with setTimeout that situation is completely impossible.

Great example from Strawberry Perl's portable shell launcher:

set drive=%~dp0
set drivep=%drive%
if #%drive:~-1%# == #\# set drivep=%drive:~0,-1%

set PATH=%drivep%\perl\site\bin;%drivep%\perl\bin;%drivep%\c\bin;%PATH%

not sure what the negative 1's doing there myself, but it works a treat!

In case of Mac OSX,

Go to Targets -> Build Phases click + to Copy new files build phases Select product directory and drop the file there.

Clean and run the project.

Why not:

ls *.{mp3,exe,mp4}

I'm not sure where I learned it - but I've been using this.

btnImg.SetImageDrawable(GetDrawable(Resource.Drawable.button_round_green));

API 23 Android 6.0

You can't install and run in one go - but you can certainly use adb to start your already installed application. Use adb shell am start to fire an intent - you will need to use the correct intent for your application though. A couple of examples:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.Settings 

will launch Settings, and

adb shell am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity 

will launch the Browser. If you want to point the Browser at a particular page, do this

adb shell am start -a android.intent.action.VIEW -n com.android.browser/.BrowserActivity http://www.google.co.uk

If you don't know the name of the activities in the APK, then do this

aapt d xmltree <path to apk> AndroidManifest.xml

the output content will includes a section like this:

   E: activity (line=32)
    A: android:theme(0x01010000)=@0x7f080000
    A: android:label(0x01010001)=@0x7f070000
    A: android:name(0x01010003)="com.anonymous.MainWindow"
    A: android:launchMode(0x0101001d)=(type 0x10)0x3
    A: android:screenOrientation(0x0101001e)=(type 0x10)0x1
    A: android:configChanges(0x0101001f)=(type 0x11)0x80
    E: intent-filter (line=33)
      E: action (line=34)
        A: android:name(0x01010003)="android.intent.action.MAIN"
        XE: (line=34)

That tells you the name of the main activity (MainWindow), and you can now run

adb shell am start -a android.intent.action.MAIN -n com.anonymous/.MainWindow

Use the -isEqualToString: method to compare the value of two strings. Using the C == operator will simply compare the addresses of the objects.

if ([category isEqualToString:@"Some String"])
{
    // Do stuff...
}

In your AssemblyVersion in AssemblyInfo.cs file, use a fixed version number instead of specifying *. The * will change the version number on each compilation. That was the issue for this exception in my case.

With Spring Data JPA and Hibernate, I was using subinterfaces of JpaRepository to look up objects belonging to a type hierarchy that was mapped using the "join" strategy. Unfortunately, the queries were returning proxies of the base type instead of instances of the expected concrete types. This prevented me from casting the results to the correct types. Like you, I came here looking for an effective way to get my entites unproxied.

Vlad has the right idea for unproxying these results; Yannis provides a little more detail. Adding to their answers, here's the rest of what you might be looking for:

The following code provides an easy way to unproxy your proxied entities:

import org.hibernate.engine.spi.PersistenceContext;
import org.hibernate.engine.spi.SessionImplementor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.jpa.repository.JpaContext;
import org.springframework.stereotype.Component;

@Component
public final class JpaHibernateUtil {

    private static JpaContext jpaContext;

    @Autowired
    JpaHibernateUtil(JpaContext jpaContext) {
        JpaHibernateUtil.jpaContext = jpaContext;
    }

    public static <Type> Type unproxy(Type proxied, Class<Type> type) {
        PersistenceContext persistenceContext =
            jpaContext
            .getEntityManagerByManagedType(type)
            .unwrap(SessionImplementor.class)
            .getPersistenceContext();
        Type unproxied = (Type) persistenceContext.unproxyAndReassociate(proxied);
        return unproxied;
    }

}

You can pass either unproxied entites or proxied entities to the unproxy method. If they are already unproxied, they'll simply be returned. Otherwise, they'll get unproxied and returned.

Hope this helps!

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});

You can create a jQuery function to unload Bootstrap CSS files at the size of 768px, and load it back when resized to lower width. This way you can design a mobile website without touching the desktop version, by using col-xs-* only

function resize() {
if ($(window).width() > 767) {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', true);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', true);
}   
else {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', false);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', false);
}
}

and

$(document).ready(function() {
$(window).resize(resize);
resize();   

if ($(window).width() > 767) {
$('link[rel=stylesheet][href~="bootstrap.min.css"]').prop('disabled', true);
$('link[rel=stylesheet][href~="bootstrap-theme.min.css"]').prop('disabled', true);
}
});

You can set triangle with position see this code for reference

.top-left-corner {
    width: 0px;
    height: 0px;
    border-top: 0px solid transparent;
    border-bottom: 55px solid transparent;
    border-left: 55px solid #289006;
    position: absolute;
    left: 0px;
    top: 0px;
}

If you're on Digital Ocean this means you need to go to /etc/nginx/sites-enabled/ and then REMOVE using rm -R digitalocean and default

It fixed it for me!

Seems based on benchmarks at JSPerf that using += is the fastest method, though not necessarily in every browser.

For building strings in the DOM, it seems to be better to concatenate the string first and then add to the DOM, rather then iteratively add it to the dom. You should benchmark your own case though.

(Thanks @zAlbee for correction)

The Question is not private or public, the question is: How is it invoked and which AOP implementation you use!

If you use (default) Spring Proxy AOP, then all AOP functionality provided by Spring (like @Transactional) will only be taken into account if the call goes through the proxy. -- This is normally the case if the annotated method is invoked from another bean.

This has two implications:

• Because private methods must not be invoked from another bean (the exception is reflection), their @Transactional Annotation is not taken into account.
• If the method is public, but it is invoked from the same bean, it will not be taken into account either (this statement is only correct if (default) Spring Proxy AOP is used).

@See Spring Reference: Chapter 9.6 9.6 Proxying mechanisms

IMHO you should use the aspectJ mode, instead of the Spring Proxies, that will overcome the problem. And the AspectJ Transactional Aspects are woven even into private methods (checked for Spring 3.0).

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

You can also write this:

SqlCommand cmd=new SqlCommand ("insert into time(project,iteration) values (@project, @iteration)", conn);
cmd.Parameters.AddWithValue("@project",name1.SelectedValue);
cmd.Parameters.AddWithValue("@iteration",iteration.SelectedValue);

The non-recursive version of the function is not too hard - here it is for integers:

long powi(long x, unsigned n)
{
    long p = x;
    long r = 1;

    while (n > 0)
    {
        if (n % 2 == 1)
            r *= p;
        p *= p;
        n /= 2;
    }

    return(r);
}

(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)

var result;_x000D_
result = "1,2,3".split(","); _x000D_
console.log(result);

More info on W3Schools describing the String Split function.

This error happened to me after my mac mini got un-plugged (so forced shutdown), and all I had to do to fix it was restart

EABI = Embedded Application Binary Interface. It is such specifications to which an executable must conform in order to execute in a specific execution environment. It also specifies various aspects of compilation and linkage required for interoperation between toolchains used for the ARM Architecture. In this context when we speak about armeabi we speak about ARM architecture and GNU/Linux OS. Android follows the little-endian ARM GNU/Linux ABI.

armeabi application will run on ARMv5 (e.g. ARM9) and ARMv6 (e.g. ARM11). You may use Floating Point hardware if you build your application using proper GCC options like -mfpu=vfpv3 -mfloat-abi=softfp which tells compiler to generate floating point instructions for VFP hardware and enables the soft-float calling conventions. armeabi doesn't support hard-float calling conventions (it means FP registers are not used to contain arguments for a function), but FP operations in HW are still supported.

armeabi-v7a application will run on Cortex A# devices like Cortex A8, A9, and A15. It supports multi-core processors and it supports -mfloat-abi=hard. So, if you build your application using -mfloat-abi=hard, many of your function calls will be faster.

I've found it useful to monkey-patch unittest as follows:

def assertMayRaise(self, exception, expr):
  if exception is None:
    try:
      expr()
    except:
      info = sys.exc_info()
      self.fail('%s raised' % repr(info[0]))
  else:
    self.assertRaises(exception, expr)

unittest.TestCase.assertMayRaise = assertMayRaise

This clarifies intent when testing for the absence of an exception:

self.assertMayRaise(None, does_not_raise)

This also simplifies testing in a loop, which I often find myself doing:

# ValueError is raised only for op(x,x), op(y,y) and op(z,z).
for i,(a,b) in enumerate(itertools.product([x,y,z], [x,y,z])):
  self.assertMayRaise(None if i%4 else ValueError, lambda: op(a, b))

Instead of using position:relative in #icons, you could just take that away and maybe add a z-index or something so the picture won't get covered up. Hope this helps.

Add the following line:

request.UseDefaultCredentials = true;

This will let the application use the credentials of the logged in user to access the site. If it's returning 403, clearly it's expecting authentication.

It's also possible that you (now?) have an authenticating proxy in between you and the remote site. In which case, try:

request.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

Hope this helps.

As I needed to use this feature for my latest project (at one point we updated from 1.10.19), just to keep the users (that are already using the mockito-core version 2.1.0 or greater) up to date, the static methods from the above answers should be taken from ArgumentMatchers class:

import static org.mockito.ArgumentMatchers.isA;
import static org.mockito.ArgumentMatchers.any;

Please keep this in mind if you are planning to keep your Mockito artefacts up to date as possibly starting from version 3, this class may no longer exist:

As per 2.1.0 and above, Javadoc of org.mockito.Matchers states:

Use org.mockito.ArgumentMatchers. This class is now deprecated in order to avoid a name clash with Hamcrest * org.hamcrest.Matchers class. This class will likely be removed in version 3.0.

I have written a little article on mockito wildcards if you're up for further reading.

Given your example, you need to add the following import in your main.main class:

import second.second;

Some bonus advice, make sure you titlecase your class names as that is a Java standard. So your example Main class will have the structure:

package main;  //lowercase package names
public class Main //titlecase class names
{
    //Main class content
}

Comments on each piece of your DTD below. Refer to official spec for more info.

  <!
  DOCTYPE ----------------------------------------- correct
  templates --------------------------------------- correct  Name matches root element.
  PUBLIC ------------------------------------------ correct  Accessing external subset via URL.
  "//UNKNOWN/" ------------------------------------ invalid? Seems useless, wrong, out-of-place.
                                                             Safely replaceable by DTD URL in next line.
  "http://fast-code.sourceforge.net/template.dtd" - invalid  URL is currently broken.
  >

Simple Explanation:

An extremely basic DTD will look like the second line here:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE nameOfYourRootElement>
<nameOfYourRootElement>
</nameOfYourRootElement>

Detailed Explanation:

DTDs serve to establish agreed upon data formats and validate the receipt of such data. They define the structure of an XML document, including:

• a list of legal elements
• special characters
• character strings
• and a lot more

E.g.

<!DOCTYPE nameOfYourRootElement
[
<!ELEMENT nameOfYourRootElement (nameOfChildElement1,nameOfChildElement2)>
<!ELEMENT nameOfChildElement1 (#PCDATA)>
<!ELEMENT nameOfChildElement2 (#PCDATA)>
<!ENTITY nbsp "&#xA0;"> 
<!ENTITY author "Your Author Name">
]>

Meaning of above lines...
Line 1) Root element defined as "nameOfYourRootElement"
Line 2) Start of element definitions
Line 3) Root element children defined as "nameOfYourRootElement1" and "nameOfYourRootElement2"
Line 4) Child element, which is defined as data type #PCDATA
Line 5) Child element, which is defined as data type #PCDATA
Line 6) Expand instances of   to   when document is parsed by XML parser
Line 7) Expand instances of &author; to Your Author Name when document is parsed by XML parser
Line 8) End of definitions

Go for the full installation of Git for windows (with Unix tool), and bison and flex would come with it in the bin folder.

GoalSeek will throw an "Invalid Reference" error if the GoalSeek cell contains a value rather than a formula or if the ChangingCell contains a formula instead of a value or nothing.

The GoalSeek cell must contain a formula that refers directly or indirectly to the ChangingCell; if the formula doesn't refer to the ChangingCell in some way, GoalSeek either may not converge to an answer or may produce a nonsensical answer.

I tested your code with a different GoalSeek formula than yours (I wasn't quite clear whether some of the terms referred to cells or values).

For the test, I set:

  the GoalSeek cell  H18 = (G18^3)+(3*G18^2)+6
  the Goal cell      H32 =  11
  the ChangingCell   G18 =  0 

The code was:

Sub GSeek()
    With Worksheets("Sheet1")
        .Range("H18").GoalSeek _
        Goal:=.Range("H32").Value, _
        ChangingCell:=.Range("G18")
    End With
End Sub

And the code produced the (correct) answer of 1.1038, the value of G18 at which the formula in H18 produces the value of 11, the goal I was seeking.

You could use .keypress().

For example, consider the HTML:

<form>
  <fieldset>
    <input id="target" type="text" value="Hello there" />
  </fieldset>
</form>
<div id="other">
  Trigger the handler
</div>

The event handler can be bound to the input field:

$("#target").keypress(function() {
  alert("Handler for .keypress() called.");
});

I totally agree with Andy; all depends on how you want it to work.

Swift is not like languages like JavaScript, where you can call a function without passing the parameters and it will still be called. So to call a function in Swift, you need to assign a value to its parameters.

Default values for parameters allow you to assign a value without specifying it when calling the function. That's why test() works when you specify a default value on test's declaration.

If you don't include that default value, you need to provide the value on the call: test(nil).

Also, and not directly related to this question, but probably worth to note, you are using the "C++" way of dealing with possibly null pointers, for dealing with possible nil optionals in Swift. The following code is safer (specially in multithreading software), and it allows you to avoid the forced unwrapping of the optional:

func test(firstThing: Int? = nil) {
    if let firstThing = firstThing {
        print(firstThing)
    }
    print("done")
}
test()

Look at the GeoIP functions under "Other Basic Extensions." http://php.net/manual/en/book.geoip.php

After reading Java 7 Update 21 Security Improvements in Detail mention..

With the introduced changes it is most likely that no end-user is able to run your application when they are either self-signed or unsigned.

..I was wondering how this would go for loose class files - the 'simplest' applets of all.

Local file system

Your security settings have blocked a local application from running

That is the dialog seen for an applet consisting of loose class files being loaded off the local file system when the JRE is set to the default 'High' security setting.

Note that a slight quirk of the JRE only produced that on point 3 of.

1. Load the applet page to see a broken applet symbol that leads to an empty console.
   Open the Java settings and set the level to Medium.
   Close browser & Java settings.
2. Load the applet page to see the applet.
   Open the Java settings and set the level to High.
   Close browser & Java settings.
3. Load the applet page to see a broken applet symbol & the above dialog.

Internet

If you load the simple applet (loose class file) seen at this resizable applet demo off the internet - which boasts an applet element of:

<applet
    code="PlafChanger.class"
    codebase="."
    alt="Pluggable Look'n'Feel Changer appears here if Java is enabled"
    width='100%'
    height='250'>
<p>Pluggable Look'n'Feel Changer appears here in a Java capable browser.</p>
</applet>

It also seems to load successfully. Implying that:-

Applets loaded from the local file system are now subject to a stricter security sandbox than those loaded from the internet or a local server.

Security settings descriptions

As of Java 7 update 51.

• Very High: Most secure setting - Only Java applications identified by a non-expired certificate from a trusted authority will be allowed to run.
• High (minimum recommended): Java applications identified by a certificate from a trusted authority will be allowed to run.
• Medium - All Java applications will be allowed to run after presenting a security prompt.

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

When you import lib, you're importing the package. The only file to get evaluated and run in this case is the 0 byte __init__.py in the lib directory.

If you want access to your function, you can do something like this from lib.mod1 import mod1 and then run the mod12 function like so mod1.mod12().

If you want to be able to access mod1 when you import lib, you need to put an import mod1 inside the __init__.py file inside the lib directory.

Best and easiest solution:

For each page you want your respective link to change color to until switched, put an internal style in EACH PAGE for the VISITED attribute and make each an individual class in order to differentiate between links so you don't apply the feature to all accidentally. We'll use white as an example:

<style type="text/css">
.link1 a:visited {color:#FFFFFF;text-decoration:none;} 
</style>

For all other attributes such as LINK, ACTIVE and HOVER, you can keep those in your style.css. You'll want to include a VISITED there as well for the color you want the link to turn back to when you click a different link.

I know this is an old question but you can use:

array_push($data, array($category => $question));

This will push the array onto the end of your current array. Or if you are just trying to add single values to the end of your array, not more arrays then you can use this:

array_push($data,$question);

You can just create a new branch and switch onto it. Commit your changes then:

git branch dirty
git checkout dirty
// And your commit follows ...

Alternatively, you can also checkout an existing branch (just git checkout <name>). But only, if there are no collisions (the base of all edited files is the same as in your current branch). Otherwise you will get a message.

You can write a jQuery function like this to determine if an element is in the viewport.

Include this somewhere after jQuery is included:

$.fn.isInViewport = function() {
    var elementTop = $(this).offset().top;
    var elementBottom = elementTop + $(this).outerHeight();

    var viewportTop = $(window).scrollTop();
    var viewportBottom = viewportTop + $(window).height();

    return elementBottom > viewportTop && elementTop < viewportBottom;
};

Sample usage:

$(window).on('resize scroll', function() {
    if ($('#Something').isInViewport()) {
        // do something
    } else {
        // do something else
    }
});

Note that this only checks the top and bottom positions of elements, it doesn't check if an element is outside of the viewport horizontally.

In SQL Server:

SELECT LEN(REPLACE(myColumn, 'N', '')) 
FROM ...

Here is code that will upload multiple images at once, into a specific folder!

The HTML:

<form method="post" enctype="multipart/form-data" id="image_upload_form" action="submit_image.php">
<input type="file" name="images" id="images" multiple accept="image/x-png, image/gif, image/jpeg, image/jpg" />
<button type="submit" id="btn">Upload Files!</button>
</form>
<div id="response"></div>
<ul id="image-list">

</ul>

The PHP:

<?php
$errors = $_FILES["images"]["error"];
foreach ($errors as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
    $name = $_FILES["images"]["name"][$key];
    //$ext = pathinfo($name, PATHINFO_EXTENSION);
    $name = explode("_", $name);
    $imagename='';
    foreach($name as $letter){
        $imagename .= $letter;
    }

    move_uploaded_file( $_FILES["images"]["tmp_name"][$key], "images/uploads/" .  $imagename);

}
}


echo "<h2>Successfully Uploaded Images</h2>";

And finally, the JavaSCript/Ajax:

(function () {
var input = document.getElementById("images"), 
    formdata = false;

function showUploadedItem (source) {
    var list = document.getElementById("image-list"),
        li   = document.createElement("li"),
        img  = document.createElement("img");
    img.src = source;
    li.appendChild(img);
    list.appendChild(li);
}   

if (window.FormData) {
    formdata = new FormData();
    document.getElementById("btn").style.display = "none";
}

input.addEventListener("change", function (evt) {
    document.getElementById("response").innerHTML = "Uploading . . ."
    var i = 0, len = this.files.length, img, reader, file;

    for ( ; i < len; i++ ) {
        file = this.files[i];

        if (!!file.type.match(/image.*/)) {
            if ( window.FileReader ) {
                reader = new FileReader();
                reader.onloadend = function (e) { 
                    showUploadedItem(e.target.result, file.fileName);
                };
                reader.readAsDataURL(file);
            }
            if (formdata) {
                formdata.append("images[]", file);
            }
        }   
    }

    if (formdata) {
        $.ajax({
            url: "submit_image.php",
            type: "POST",
            data: formdata,
            processData: false,
            contentType: false,
            success: function (res) {
                document.getElementById("response").innerHTML = res;
            }
        });
    }
}, false);
}());

Hope this helps

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

Note also that vertical-align:top; is often necessary for correct table cell appearance.

css table-cell, contents have unnecessary top margin

There is another error with the forwars=d slash.

if we get this : def get_x(r): return path/'train'/r['fname']
is the same as def get_x(r): return path + 'train' + r['fname']

I want to share this code I wrote for the issue I had to resolve. It was tested in most of the major browsers and works like a charm, for me!

It may seems that this code is very similar to the other answers but it modifyed so that I can use it insted of the browser object in jquery which missed for me recently, of course it is a combination from the above codes, with little improvements from my part I made:

(function($, ua){

var M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\/))\/?\s*(\d+)/i) || [],
    tem, 
    res;

if(/trident/i.test(M[1])){
    tem = /\brv[ :]+(\d+)/g.exec(ua) || [];
    res = 'IE ' + (tem[1] || '');
}
else if(M[1] === 'Chrome'){
    tem = ua.match(/\b(OPR|Edge)\/(\d+)/);
    if(tem != null) 
        res = tem.slice(1).join(' ').replace('OPR', 'Opera');
    else
        res = [M[1], M[2]];
}
else {
    M = M[2]? [M[1], M[2]] : [navigator.appName, navigator.appVersion, '-?'];
    if((tem = ua.match(/version\/(\d+)/i)) != null) M = M.splice(1, 1, tem[1]);
    res = M;
}

res = typeof res === 'string'? res.split(' ') : res;

$.browser = {
    name: res[0],
    version: res[1],
    msie: /msie|ie/i.test(res[0]),
    firefox: /firefox/i.test(res[0]),
    opera: /opera/i.test(res[0]),
    chrome: /chrome/i.test(res[0]),
    edge: /edge/i.test(res[0])
}

})(typeof jQuery != 'undefined'? jQuery : window.$, navigator.userAgent);

 console.log($.browser.name, $.browser.version, $.browser.msie); 
// if IE 11 output is: IE 11 true

reverse() | Django documentation

Let's suppose that in your urls.py you have defined this:

url(r'^foo$', some_view, name='url_name'),

In a template you can then refer to this url as:

<!-- django <= 1.4 -->
<a href="{% url url_name %}">link which calls some_view</a>

<!-- django >= 1.5 or with {% load url from future %} in your template -->
<a href="{% url 'url_name' %}">link which calls some_view</a>

This will be rendered as:

<a href="/foo/">link which calls some_view</a>

Now say you want to do something similar in your views.py - e.g. you are handling some other url (not /foo/) in some other view (not some_view) and you want to redirect the user to /foo/ (often the case on successful form submission).

You could just do:

return HttpResponseRedirect('/foo/')

But what if you want to change the url in future? You'd have to update your urls.py and all references to it in your code. This violates DRY (Don't Repeat Yourself), the whole idea of editing one place only, which is something to strive for.

Instead, you can say:

from django.urls import reverse
return HttpResponseRedirect(reverse('url_name'))

This looks through all urls defined in your project for the url defined with the name url_name and returns the actual url /foo/.

This means that you refer to the url only by its name attribute - if you want to change the url itself or the view it refers to you can do this by editing one place only - urls.py.

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')

Queue<String> qe=new LinkedList<String>();

qe.add("b");
qe.add("a");
qe.add("c");

Since Queue is an interface, you can't create an instance of it as you illustrated

I tried many thing to get DELETE method work (I was getting 405 method not allowed web api) , and finally I added [Route("api/scan/{id}")] to my controller and was work fine. hope this post help some one.

     // DELETE api/Scan/5
    [Route("api/scan/{id}")]
    [ResponseType(typeof(Scan))]
    public IHttpActionResult DeleteScan(int id)
    {
        Scan scan = db.Scans.Find(id);
        if (scan == null)
        {
            return NotFound();
        }

        db.Scans.Remove(scan);
        db.SaveChanges();

        return Ok(scan);
    }

DbContext has a constructor overload that accepts the name of a connection string or a connection string itself. Implement your own version and pass it to the base constructor:

public class MyDbContext : DbContext
{
    public MyDbContext( string nameOrConnectionString ) 
        : base( nameOrConnectionString )
    {
    }
}

Then simply pass the name of a configured connection string or a connection string itself when you instantiate your DbContext

var context = new MyDbContext( "..." );

You should use the string.Join method to turn a collection of items into a comma delimited string. It will ensure that there is no leading or trailing comma, as well as ensure the string is constructed efficiently (without unnecessary intermediate strings).

Nope, you'd just have to create your own function:

function printr($data) {
   echo "<pre>";
      print_r($data);
   echo "</pre>";
}

Apparantly, in 2018, people are still coming back to this question. The above would not be my current answer. I'd say: teach your editor to do it for you. I have a whole bunch of debug shortcuts, but my most used is vardd which expands to: var_dump(__FILE__ . ':' . __LINE__, $VAR$);die();

You can configure this in PHPStorm as a live template.

on windows 10, Notepad 7.8.5, i found this solution to convert from CRLF to LF.
Edit > Format end of line
and choose either Windows(CR+LF) or Unix(LF)

I was looking for the same funcionality and found this answer. However, I wanted to give you guys a quick update. It's CSS3's vmin unit.

p, li
{
  font-size: 1.2vmin;
}

vmin means 'whichever is smaller between the 1% of the ViewPort's height and the 1% of the ViewPort's width'.

Alternately, if you are using a Macro Enabled workbook:

Add any control at all from the Developer -> Insert (Probably a button)

When it asks what Macro to assign, choose New. For the code for the generated module enter something like:

Thisworkbook.Sheets("Sheet Name").Activate

However, if you are not using Macros in your work book. Ooo's approach is definitely surperior as hyperlinks will work with no need to trust the document.

Java binaries may be under "Program Files" or "Program Files (x86)": those white spaces will likely affect the behaviour.

In order to set up env variables correctly, I suggest gathering some info before starting:

• Open DOS shell (type cmd into 'RUN' box) go to C:\
• type "dir /x" and take note of DOS names (with ~) for "Program Files *" folders

Cygwin configuration:

go under C:\cygwin\home\, then open .bash_profile and add the following two lines (conveniently customized in order to match you actual JDK path)

export JAVA_HOME="/cygdrive/c/PROGRA~1/Java/jdk1.8.0_65"
export PATH="$JAVA_HOME/bin:$PATH"

Now from Cygwin launch

javac -version

to check if the configuration is successful.

This is impossible as a child's z-index is set to the same stacking index as its parent.

You have already solved the problem by removing the z-index from the parent, keep it like this or make the element a sibling instead of a child.

Netscape ANSI encoded files use 0D 0D 0A for their line breaks.

It's too late to answer this question, but it could help for new readers, It seems version issues. I ran all these tests with spring 4.1.4 and found that the order of @RequestBody and @RequestParam doesn't matter.

1. same as your result
2. same as your result
3. gave body= "name=abc", and name = "abc"
4. Same as 3.
5. body ="name=abc", name = "xyz,abc"
6. same as 5.

To add the latest solution for 2021...

I found that the project nanoid provides unique string ids that can be used as key while also being fast and very small.

After installing using npm install nanoid, use as follows:

import { nanoid } from 'nanoid';

// Have the id associated with the data.
const todos = [{id: nanoid(), text: 'first todo'}];

// Then later, it can be rendered using a stable id as the key.
const todoItems = todos.map((todo) =>
  <li key={todo.id}>
    {todo.text}
  </li>
)

 SELECT * from
 (
 select m.*, rownum r
 from maps006 m
 )
 where r > 49 and r < 101

Changing from 32 to 64 bit worked for me - worth a try if you are on a 64 bit pc and it doesn't need to port.

Other (undocumented) way to do it, is to call:

$("form").validate().cancelSubmit = true;

on the click event of the button (for example).

For others facing a similar problem to mine, where you know a particular object property cannot be null, you can use the non-null assertion operator (!) after the item in question. This was my code:

  const naciStatus = dataToSend.naci?.statusNACI;
  if (typeof naciStatus != "undefined") {
    switch (naciStatus) {
      case "AP":
        dataToSend.naci.certificateStatus = "FALSE";
        break;
      case "AS":
      case "WR":
        dataToSend.naci.certificateStatus = "TRUE";
        break;
      default:
        dataToSend.naci.certificateStatus = "";
    }
  }

And because dataToSend.naci cannot be undefined in the switch statement, the code can be updated to include exclamation marks as follows:

  const naciStatus = dataToSend.naci?.statusNACI;
  if (typeof naciStatus != "undefined") {
    switch (naciStatus) {
      case "AP":
        dataToSend.naci!.certificateStatus = "FALSE";
        break;
      case "AS":
      case "WR":
        dataToSend.naci!.certificateStatus = "TRUE";
        break;
      default:
        dataToSend.naci!.certificateStatus = "";
    }
  }

foreach (var item in dicNumber)
{
    listnumber.Add(item.Key);
}

Just:

_.omit(my_object, _.isUndefined)

The above doesn't take in account null values, as they are missing from the original example and mentioned only in the subject, but I leave it as it is elegant and might have its uses.

Here is the complete example, less concise, but more complete.

var obj = { a: undefined, b: 2, c: 4, d: undefined, e: null, f: false, g: '', h: 0 };
console.log(_.omit(obj, function(v) { return _.isUndefined(v) || _.isNull(v); }));

The data.table package introduced the IDate class some time ago and zoo-package-like functions to retrieve months, days, etc (Check ?IDate). so, you can extract the desired info now in the following ways:

require(data.table)
df <- data.frame(id = 1:3,
                 date = c("2004-02-06" , "2006-03-14" , "2007-07-16"))
setDT(df)
df[ , date := as.IDate(date) ] # instead of as.Date()
df[ , yrmn := paste0(year(date), '-', month(date)) ]
df[ , yrmn2 := format(date, '%Y-%m') ]

In Eclipse:

• Right click on your build.xml

• click "Run As", click on "External Tool Configurations..."

• Select tab JRE. Select the JRE you are using.

Re-run the task, it should be fine now.

Note: "schtasks" (see the other, accepted response) has replaced "at". However, "at" may be of use if the situation calls for compatibility with older versions of Windows that don't have schtasks.

xmlstarlet sel -t -m '//title[1]' -v . -n <data.xml

Trying to use sed for this job is troublesome. For instance, the regex-based approaches won't work if the title has attributes; won't handle CDATA sections; won't correctly recognize namespace mappings; can't determine whether a portion of the XML documented is commented out; won't unescape attribute references (such as changing Brewster & Jobs to Brewster & Jobs), and so forth.

Using of NSHTMLTextDocumentType is slow and it is hard to control styles. I suggest you to try my library which is called Atributika. It has its own very fast HTML parser. Also you can have any tag names and define any style for them.

Example:

let str = "<strong>Hello</strong> World!".style(tags:
    Style("strong").font(.boldSystemFont(ofSize: 15))).attributedString

label.attributedText = str

You can find it here https://github.com/psharanda/Atributika

Made up example

Imagine that you want to create the following sequence: 1, 2, 2, 3, 3, 3, 4, 4, 4, 4 etc. (in other words: 1x1, 2x2, 3x3 etc.)

With flatMap it could look like:

IntStream sequence = IntStream.rangeClosed(1, 4)
                          .flatMap(i -> IntStream.iterate(i, identity()).limit(i));
sequence.forEach(System.out::println);

where:

• IntStream.rangeClosed(1, 4) creates a stream of int from 1 to 4, inclusive
• IntStream.iterate(i, identity()).limit(i) creates a stream of length i of int i - so applied to i = 4 it creates a stream: 4, 4, 4, 4
• flatMap "flattens" the stream and "concatenates" it to the original stream

With Java < 8 you would need two nested loops:

List<Integer> list = new ArrayList<>();
for (int i = 1; i <= 4; i++) {
    for (int j = 0; j < i; j++) {
        list.add(i);
    }
}

Real world example

Let's say I have a List<TimeSeries> where each TimeSeries is essentially a Map<LocalDate, Double>. I want to get a list of all dates for which at least one of the time series has a value. flatMap to the rescue:

list.stream().parallel()
    .flatMap(ts -> ts.dates().stream()) // for each TS, stream dates and flatmap
    .distinct()                         // remove duplicates
    .sorted()                           // sort ascending
    .collect(toList());

Not only is it readable, but if you suddenly need to process 100k elements, simply adding parallel() will improve performance without you writing any concurrent code.

As you probably use a drawable selector for your android:button property you need to add android:constantSize="true" and/or specify a default drawable like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:constantSize="true">
  <item android:drawable="@drawable/check_on" android:state_checked="true"/>
  <item android:drawable="@drawable/check_off"/>
</selector>

After that you need to specify android:paddingLeft attribute in your checkbox xml.

Cons:

In the layout editor you will the text going under the checkbox with api 16 and below, in that case you can fix it by creating you custom checkbox class like suggested but for api level 16.

Rationale:

it is a bug as StateListDrawable#getIntrinsicWidth() call is used internally in CompoundButton but it may return < 0 value if there is no current state and no constant size is used.

BTW... there are a few proper ways how to display site copyright. Some people have tendency to make things redundant i.e.: Copyright © have both the same meaning. The important copyright parts are:

**Symbol, Year, Author/Owner and Rights statement.** 

Using PHP + HTML:

<p id='copyright'>&copy; <?php echo date("Y"); ?> Company Name All Rights Reserved</p>

or

<p id='copyright'>&copy; <?php echo "2010-".date("Y"); ?> Company Name All Rights Reserved</p

If this is in SQL Server, your syntax is correct; however, you need to reference the COUNT(*) as the Total Count from your nested query. This should give you what you need:

SELECT CASE WHEN TotalCount >0 THEN 'TRUE' ELSE 'FALSE' END FROM
(
  SELECT [Some Column], COUNT(*) TotalCount
  FROM INCIDENTS
  WHERE [Some Column] = 'Target Data'
  GROUP BY [Some Column]
) DerivedTable

Using this, you could assign TotalCount to a variable and then use an IF ELSE statement to execute your INSERT statements:

DECLARE @TotalCount int
SELECT @TotalCount = TotalCount FROM
(
  SELECT [Some Column], COUNT(*) TotalCount
  FROM INCIDENTS
  WHERE [Some Column] = 'Target Data'
  GROUP BY [Some Column]
) DerivedTable
IF @TotalCount > 0
    -- INSERT STATEMENT 1 GOES HERE
ELSE
    -- INSERT STATEMENT 2 GOES HERE

In my case both node and npm were in same path (/usr/bin). The NODE_PATH was empty, so the npm placed the global modules into /usr/lib/node_modules where require(...) successfully find them. The only exception was the npm module, which came with the nodejs package. Since I'm using 64 bit system, it was placed into /usr/lib64/node_modules. This is not where require(...) searches in case of empty NODE_PATH and node started from /usr/bin. So I had two options:

• link /usr/lib64/node_modules/npm to /usr/lib/node_modules/npm
• move modules from /usr/lib/node_modules/* to /usr/lib64/node_modules/ and set NODE_PATH=/usr/lib64/node_modules

Both worked. I'm using OpenSUSE 42.1 and the nodejs package from updates repository. Version is 4.4.5.

Using lambdas and functional interfaces in Java 8 makes creating new loop abstractions possible. I can loop over a collection with the index and the collection size:

List<String> strings = Arrays.asList("one", "two","three","four");
forEach(strings, (x, i, n) -> System.out.println("" + (i+1) + "/"+n+": " + x));

Which outputs:

1/4: one
2/4: two
3/4: three
4/4: four

Which I implemented as:

   @FunctionalInterface
   public interface LoopWithIndexAndSizeConsumer<T> {
       void accept(T t, int i, int n);
   }
   public static <T> void forEach(Collection<T> collection,
                                  LoopWithIndexAndSizeConsumer<T> consumer) {
      int index = 0;
      for (T object : collection){
         consumer.accept(object, index++, collection.size());
      }
   }

The possibilities are endless. For example, I create an abstraction that uses a special function just for the first element:

forEachHeadTail(strings, 
                (head) -> System.out.print(head), 
                (tail) -> System.out.print(","+tail));

Which prints a comma separated list correctly:

one,two,three,four

Which I implemented as:

public static <T> void forEachHeadTail(Collection<T> collection, 
                                       Consumer<T> headFunc, 
                                       Consumer<T> tailFunc) {
   int index = 0;
   for (T object : collection){
      if (index++ == 0){
         headFunc.accept(object);
      }
      else{
         tailFunc.accept(object);
      }
   }
}

Libraries will begin to pop up to do these sorts of things, or you can roll your own.

I was able to copy all the sheets in a workbook that had a vba app running, to a new workbook w/o the app macros, with:

ActiveWorkbook.Sheets.Copy

For those wanting a more secure way to create a random byte array, yes the most secure way is:

byte[] bytes = new byte[20];
SecureRandom.getInstanceStrong().nextBytes(bytes);

BUT your threads might block if there is not enough randomness available on the machine, depending on your OS. The following solution will not block:

SecureRandom random = new SecureRandom();
byte[] bytes = new byte[20];
random.nextBytes(bytes);

This is because the first example uses /dev/random and will block while waiting for more randomness (generated by a mouse/keyboard and other sources). The second example uses /dev/urandom which will not block.

Agreed with jcadcell comments, but had to use JDK 1.8 because my eclipse need that. So I just copied the MSVCR71.DLL from jdk1.6 and pasted into jdk1.8 in both the folder jdk1.8.0_121\bin and jdk1.8.0_121\jre\bin

and it Worked .... Wow... Thanks :)

In Ubuntu 16.04 default PHP version is 7.0, if you want to use different version then you need to install PHP package according to PHP version:

• PHP 7.4: sudo apt-get install php7.4-curl
• PHP 7.3: sudo apt-get install php7.3-curl
• PHP 7.2: sudo apt-get install php7.2-curl
• PHP 7.1: sudo apt-get install php7.1-curl
• PHP 7.0: sudo apt-get install php7.0-curl
• PHP 5.6: sudo apt-get install php5.6-curl
• PHP 5.5: sudo apt-get install php5.5-curl

You can use include/include_once or require/require_once

require_once('class.php');

Alternatively, use autoloading by adding to page.php

<?php 
function my_autoloader($class) {
    include 'classes/' . $class . '.class.php';
}

spl_autoload_register('my_autoloader');

$vars = new IUarts(); 
print($vars->data);    
?>

It also works adding that __autoload function in a lib that you include on every file like utils.php.

There is also this post that has a nice and different approach.

Efficient PHP auto-loading and naming strategies

Simple and powerful way(dynamic validation)

place formats in array like "image/*"

var upload=document.getElementById("upload");
var array=["video/mp4","image/png"];
upload.accept=array;
upload.addEventListener("change",()=>{

console.log(upload.value)
})

<input type="file" id="upload" >

I assume you used splice something like this?

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) !== -1) {
        arrayOfObjects.splice(i, 1);
    }
}

All you need to do to fix the bug is decrement i for the next time around, then (and looping backwards is also an option):

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) !== -1) {
        arrayOfObjects.splice(i, 1);
        i--;
    }
}

To avoid linear-time deletions, you can write array elements you want to keep over the array:

var end = 0;

for (var i = 0; i < arrayOfObjects.length; i++) {
    var obj = arrayOfObjects[i];

    if (listToDelete.indexOf(obj.id) === -1) {
        arrayOfObjects[end++] = obj;
    }
}

arrayOfObjects.length = end;

and to avoid linear-time lookups in a modern runtime, you can use a hash set:

const setToDelete = new Set(listToDelete);
let end = 0;

for (let i = 0; i < arrayOfObjects.length; i++) {
    const obj = arrayOfObjects[i];

    if (setToDelete.has(obj.id)) {
        arrayOfObjects[end++] = obj;
    }
}

arrayOfObjects.length = end;

which can be wrapped up in a nice function:

const filterInPlace = (array, predicate) => {_x000D_
    let end = 0;_x000D_
_x000D_
    for (let i = 0; i < array.length; i++) {_x000D_
        const obj = array[i];_x000D_
_x000D_
        if (predicate(obj)) {_x000D_
            array[end++] = obj;_x000D_
        }_x000D_
    }_x000D_
_x000D_
    array.length = end;_x000D_
};_x000D_
_x000D_
const toDelete = new Set(['abc', 'efg']);_x000D_
_x000D_
const arrayOfObjects = [{id: 'abc', name: 'oh'},_x000D_
                        {id: 'efg', name: 'em'},_x000D_
                        {id: 'hij', name: 'ge'}];_x000D_
_x000D_
filterInPlace(arrayOfObjects, obj => !toDelete.has(obj.id));_x000D_
console.log(arrayOfObjects);

If you don’t need to do it in place, that’s Array#filter:

const toDelete = new Set(['abc', 'efg']);
const newArray = arrayOfObjects.filter(obj => !toDelete.has(obj.id));

The python-shell module by extrabacon is a simple way to run Python scripts from Node.js with basic, but efficient inter-process communication and better error handling.

Installation: npm install python-shell.

Running a simple Python script:

var PythonShell = require('python-shell');

PythonShell.run('my_script.py', function (err) {
  if (err) throw err;
  console.log('finished');
});

Running a Python script with arguments and options:

var PythonShell = require('python-shell');

var options = {
  mode: 'text',
  pythonPath: 'path/to/python',
  pythonOptions: ['-u'],
  scriptPath: 'path/to/my/scripts',
  args: ['value1', 'value2', 'value3']
};

PythonShell.run('my_script.py', options, function (err, results) {
  if (err) 
    throw err;
  // Results is an array consisting of messages collected during execution
  console.log('results: %j', results);
});

For the full documentation and source code, check out https://github.com/extrabacon/python-shell

mkdir -p sam

• mkdir = Make Directory
• -p = --parents
• (no error if existing, make parent directories as needed)

The solution that really works turned out to be setting simple error handler with E_WARNING parameter, like so:

set_error_handler("warning_handler", E_WARNING);
dns_get_record(...)
restore_error_handler();

function warning_handler($errno, $errstr) { 
// do something
}

See the defaultValue property of a text input, it's also used when you reset the form by clicking an <input type="reset"/> button (http://www.w3schools.com/jsref/prop_text_defaultvalue.asp )

btw, defaultValue and placeholder text are different concepts, you need to see which one better fits your needs

As alternate solution, based on javascript logic operator '&&' which returns the last evaluation, you can also do this like so:

<i ng-class="autoScroll && 'icon-autoscroll' || !autoScroll && 'icon-autoscroll-disabled'"></i>

It's only slightly shorter syntax, but for me easier to read.

The first bin in the FFT is DC (0 Hz), the second bin is Fs / N, where Fs is the sample rate and N is the size of the FFT. The next bin is 2 * Fs / N. To express this in general terms, the nth bin is n * Fs / N.

So if your sample rate, Fs is say 44.1 kHz and your FFT size, N is 1024, then the FFT output bins are at:

  0:   0 * 44100 / 1024 =     0.0 Hz
  1:   1 * 44100 / 1024 =    43.1 Hz
  2:   2 * 44100 / 1024 =    86.1 Hz
  3:   3 * 44100 / 1024 =   129.2 Hz
  4: ...
  5: ...
     ...
511: 511 * 44100 / 1024 = 22006.9 Hz

Note that for a real input signal (imaginary parts all zero) the second half of the FFT (bins from N / 2 + 1 to N - 1) contain no useful additional information (they have complex conjugate symmetry with the first N / 2 - 1 bins). The last useful bin (for practical aplications) is at N / 2 - 1, which corresponds to 22006.9 Hz in the above example. The bin at N / 2 represents energy at the Nyquist frequency, i.e. Fs / 2 ( = 22050 Hz in this example), but this is in general not of any practical use, since anti-aliasing filters will typically attenuate any signals at and above Fs / 2.

Based on @Jim Lewis's approach:

Here is a quick solution using find and also sorting files by their modification date:

$ find  directory/ -maxdepth 1 -type f -print0 | \
  xargs -r0 stat -c "%y %n" | \
  sort | cut -d' ' -f4- | \
  xargs -d "\n" -I{} cmd -op1 {} 

For sorting see:

I really wanted to comment, not answer. But just to be precise, OSX is not based on BSD, it is an evolution of NeXTStep. The NeXTStep OS utilizes the Mach kernel developed by CMU. It was originally designed as a MicroKernel, but due to performance constraints, they eventually decided they needed to include the Unix portion of the API into the kernel itself and so a BSD-compatible "server" (originally intended to process requests for BSD-compatible kernel messages) was moved into the kernel, making it a Monolithic kernel. It may be BSD compatible in the programming API, but it is NOT BSD.

The rest of the OS involved ObjectiveC (under arrangements between Stepstone and Richard Stallman of GNU/GCC) with a GUI based on a technology called "Display Postscript" ... sort of like an X Server, but with postscript commands. OS X changed Display Postscript to Display PDF, and increased the general hardware requirements 1000 fold (NeXT could run in 8-16MB, now you need GB).

Due to the close marriage of GCC and Objective C and NeXT, your best bet at running XCode natively under Linux would be to do a port (if you can get ahold of the source - good luck) utilizing the GNUStep libraries. Originally designed for NextStep and then OpenStep compatibility, I've heard they are now more-or-less Cocoa compatible, but I've not played with any of it in almost 2 decades. Of course that only gets you as far as ObjC, not Swift, and I don't know if Apple is going to OpenSource it.

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

I would say echo() ing them directly into the Javascript source code is the most reliable and downward compatible way. Stay with that unless you have a good reason not to.

urlresolver has been removed in the higher version of Django - Please upgrade your django installation. I fixed it using the following command.

You can use this code to set part of your text to bold. For whatever is in between the bold html tags, it will make it bold.

String myText = "make this <b>bold</b> and <b>this</b> too";
textView.setText(makeSpannable(myText, "<b>(.+?)</b>", "<b>", "</b>"));

public SpannableStringBuilder makeSpannable(String text, String regex, String startTag, String endTag) {

            StringBuffer sb = new StringBuffer();
            SpannableStringBuilder spannable = new SpannableStringBuilder();

            Pattern pattern = Pattern.compile(regex);
            Matcher matcher = pattern.matcher(text);
            while (matcher.find()) {
                sb.setLength(0);
                String group = matcher.group();
                String spanText = group.substring(startTag.length(), group.length() - endTag.length());
                matcher.appendReplacement(sb, spanText);

                spannable.append(sb.toString());
                int start = spannable.length() - spanText.length();

                spannable.setSpan(new android.text.style.StyleSpan(android.graphics.Typeface.BOLD), start, spannable.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            }
            sb.setLength(0);
            matcher.appendTail(sb);
            spannable.append(sb.toString());
            return spannable;
        }

Here is a brief analysis of the difference put out by the Android development team:

https://www.youtube.com/watch?v=MZOf3pOAM6A

The result is that there is a difference, and in very restrained environments with very large lists it could be a noticeable difference. In their testing, the for each loop took twice as long. However, their testing was over an arraylist of 400,000 integers. The actual difference per element in the array was 6 microseconds. I haven't tested and they didn't say, but I would expect the difference to be slightly larger using objects rather than primitives, but even still unless you are building library code where you have no idea the scale of what you will be asked to iterate over, I think the difference is not worth stressing about.

you could do this, if you want to use the old syntax (or don't want to rewrite every template)

@for $i from 1 through $grid-columns {
  @include media-breakpoint-up(xs) {
    .col-xs-#{$i} {
      @include make-col-ready();
      @include make-col($i);
    }
  }
}

Here is the Code snippet to find the closest element to a number from an array in Complexity O(nlog(n)) :-

Input :- {1,60,0,-10,100,87,56} Element:- 56 Closest Number in Array:- 60

Source Code (Java):

package com.algo.closestnumberinarray;
import java.util.TreeMap;


public class Find_Closest_Number_In_Array {

    public static void main(String arsg[]) {
        int array[] = { 1, 60, 0, -10, 100, 87, 69 };
        int number = 56;
        int num = getClosestNumber(array, number);
        System.out.println("Number is=" + num);
    }

    public static int getClosestNumber(int[] array, int number) {
        int diff[] = new int[array.length];

        TreeMap<Integer, Integer> keyVal = new TreeMap<Integer, Integer>();
        for (int i = 0; i < array.length; i++) {

            if (array[i] > number) {
                diff[i] = array[i] - number;
                keyVal.put(diff[i], array[i]);
            } else {
                diff[i] = number - array[i];
                keyVal.put(diff[i], array[i]);
            }

        }

        int closestKey = keyVal.firstKey();
        int closestVal = keyVal.get(closestKey);

        return closestVal;
    }
}

ADD following -

• look up for: # The MySQL server [mysqld]
• add this right below it: lower_case_table_names = 1 In file - /etc/mysql/mysql.conf.d/mysqld.cnf

It's works for me.

Create this class as Extension:

public static class Extensiones
{
    public static string FolderName(this OpenFileDialog ofd)
    {
            string resp = "";
            resp = ofd.FileName.Substring(0, 3);
            var final = ofd.FileName.Substring(3);
            var info = final.Split('\\');
            for (int i = 0; i < info.Length - 1; i++)
            {
                resp += info[i] + "\\";
            }
            return resp;
    }
}

Then, you could use in this way:

        //ofdSource is an OpenFileDialog 
        if (ofdSource.ShowDialog(this) == DialogResult.OK)
        {
            MessageBox.Show(ofdSource.FolderName());
        }

Single-dimensional arrays

For converting single-dimension arrays, you can cast using (array) or there's get_object_vars, which Benoit mentioned in his answer.

// Cast to an array
$array = (array) $object;

// get_object_vars
$array = get_object_vars($object);

They work slightly different from each other. For example, get_object_vars will return an array with only publicly accessible properties unless it is called from within the scope of the object you're passing (ie in a member function of the object). (array), on the other hand, will cast to an array with all public, private and protected members intact on the array, though all public now, of course.

Multi-dimensional arrays

A somewhat dirty method is to use PHP >= 5.2's native JSON functions to encode to JSON and then decode back to an array. This will not include private and protected members, however, and is not suitable for objects that contain data that cannot be JSON encoded (such as binary data).

// The second parameter of json_decode forces parsing into an associative array
$array = json_decode(json_encode($object), true);

Alternatively, the following function will convert from an object to an array including private and protected members, taken from here and modified to use casting:

function objectToArray ($object) {
    if(!is_object($object) && !is_array($object))
        return $object;

    return array_map('objectToArray', (array) $object);
}

The issue was with the dmp file itself. I had to re-export the file and the command works fine. Thank you @Justin Cave

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

Another way to make it in Python 3:

numbers = [*map(int, numbers)]

public static String readFile(String fn)   throws IOException 
{
    File f = new File(fn);

    byte[] buffer = new byte[(int)f.length()];
    FileInputStream is = new FileInputStream(fn);
    is.read(buffer);
    is.close();

    return  new String(buffer, "UTF-8"); // use desired encoding

The size arguments are in pixels. So, to double your example's marker size the fifth argument to the MarkerImage constructor would be:

new google.maps.Size(42,68)

I find it easiest to let the map API figure out the other arguments, unless I need something other than the bottom/center of the image as the anchor. In your case you could do:

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + pinColor,
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);

For .Net core i had many problems using SSH.net and also its deprecated. I tried a few other libraries, even for other programming languages. But i found a very good alternative. https://stackoverflow.com/a/64443701/8529170

I disagree with this kind of path

GET /companies/{companyId}/departments

If you want to get departments, I think it's better to use a /departments resource

GET /departments?companyId=123

I suppose you have a companies table and a departments table then classes to map them in the programming language you use. I also assume that departments could be attached to other entities than companies, so a /departments resource is straightforward, it's convenient to have resources mapped to tables and also you don't need as many endpoints since you can reuse

GET /departments?companyId=123

for any kind of search, for instance

GET /departments?name=xxx
GET /departments?companyId=123&name=xxx
etc.

If you want to create a department, the

POST /departments

resource should be used and the request body should contain the company ID (if the department can be linked to only one company).

To delete a web property, you simply need to delete every profile within the property. Once the last profile has been deleted, the web property with cease to exist in the GA account. That's all there is to it! -- Source

You have to disable the sandbox for Groovy in your job configuration.

Currently this is not possible for multibranch projects where the groovy script comes from the scm. For more information see https://issues.jenkins-ci.org/browse/JENKINS-28178

If you are using it in a script, use stat.

$ date | tee /tmp/foo
Wed Mar 13 05:36:31 UTC 2019

$ stat -c %s /tmp/foo
29

$ ls -l /tmp/foo
-rw-r--r--  1 bruno  wheel  29 Mar 13 05:36 /tmp/foo

That will give you size in bytes. See man stat for more output format options.

The OSX/BSD equivalent is:

$ date | tee /tmp/foo
Wed Mar 13 00:54:16 EDT 2019

$ stat -f %z /tmp/foo
29

$ ls -l /tmp/foo
-rw-r--r--  1 bruno  wheel  29 Mar 13 00:54 /tmp/foo

Here is the Java 8+ example:

public static void pack(String sourceDirPath, String zipFilePath) throws IOException {
    Path p = Files.createFile(Paths.get(zipFilePath));
    try (ZipOutputStream zs = new ZipOutputStream(Files.newOutputStream(p))) {
        Path pp = Paths.get(sourceDirPath);
        Files.walk(pp)
          .filter(path -> !Files.isDirectory(path))
          .forEach(path -> {
              ZipEntry zipEntry = new ZipEntry(pp.relativize(path).toString());
              try {
                  zs.putNextEntry(zipEntry);
                  Files.copy(path, zs);
                  zs.closeEntry();
            } catch (IOException e) {
                System.err.println(e);
            }
          });
    }
}

If you don't want to use the KnockoutValidation library you can write your own. Here's an example for a Mandatory field.

Add a javascript class with all you KO extensions or extenders, and add the following:

ko.extenders.required = function (target, overrideMessage) {
    //add some sub-observables to our observable
    target.hasError = ko.observable();
    target.validationMessage = ko.observable();

    //define a function to do validation
    function validate(newValue) {
    target.hasError(newValue ? false : true);
    target.validationMessage(newValue ? "" : overrideMessage || "This field is required");
    }

    //initial validation
    validate(target());

    //validate whenever the value changes
    target.subscribe(validate);

    //return the original observable
    return target;
};

Then in your viewModel extend you observable by:

self.dateOfPayment: ko.observable().extend({ required: "" }),

There are a number of examples online for this style of validation.

This blog post may be a good start: http://benno.id.au/blog/2007/11/13/android-native-apps Unfortunately, lots of the important stuff is "left as an exercise to the reader".

Subtract char '0' or int 48 like this:

char c = '5';
int i = c - '0';

Explanation: Internally it works with ASCII value. From the ASCII table, decimal value of character 5 is 53 and 0 is 48. So 53 - 48 = 5

OR

char c = '5';
int i = c - 48; // Because decimal value of char '0' is 48

That means if you deduct 48 from any numeral character, it will convert integer automatically.

No, destructors are called automatically in the reverse order of construction. (Base classes last). Do not call base class destructors.

For swift 3.0 and above

public static func getTopViewController() -> UIViewController?{
if var topController = UIApplication.shared.keyWindow?.rootViewController
{
  while (topController.presentedViewController != nil)
  {
    topController = topController.presentedViewController!
  }
  return topController
}
return nil}

I think a regex is a little bit of an overkill in this situation. If you just want to remove all the quotes in your string I would use this code:

details = details.replace("\"", "");

Solutions

Data

import Foundation

let array = [0,1,2,3,4,5,6,7,8]

Solution 1

extension Int {

    func getString(prefix: Int) -> String {
        return "\(prefix)\(self)"
    }

    func getString(prefix: String) -> String {
        return "\(prefix)\(self)"
    }
}

for item in array {
    print(item.getString(prefix: 0))
}

for item in array {
    print(item.getString(prefix: "0x"))
}

Solution 2

for item in array {
    print(String(repeatElement("0", count: 2)) + "\(item)")
}

Solution 3

extension String {

    func repeate(count: Int, string: String? = nil) -> String {

        if count > 1 {
            let repeatedString = string ?? self
            return repeatedString + repeate(count: count-1, string: repeatedString)
        }
        return self
    }
}

for item in array {
    print("0".repeate(count: 3) + "\(item)")
}

Here

{int y=((year-1)%100);int c=(year-1)/100;}

you declare and initialize the variables y, c, but you don't used them at all before they run out of scope. That's why you get the unused message.

Later in the function, y, c are undeclared, because the declarations you made only hold inside the block they were made in (the block between the braces {...}).

Another possibility is that you need to add ?wsdl at the end of your service url for SoapUI. That one got me as I'm used to WCFClient which didn't need it.

You can also use this

let str = "hello single ' double \" and slash \\ yippie";

let escapeStr = escape(str);
document.write("<b>str : </b>"+str);
document.write("<br/><b>escapeStr : </b>"+escapeStr);
document.write("<br/><b>unEscapeStr : </b> "+unescape(escapeStr));

1. The query is correct

2A. As far as last seven days have much less rows than whole table an index can help

2B. If you are interested only in Created_Date you can try using some group by and count, it should help with the result set size

None of the above worked for me. (substitution on \r, ^M, ctrl-v-ctrl-m ) I used copy and paste to paste my text into a new file.

If you have macros that interfere, you can try :set paste before the paste operation and :set nopaste after.

Use:

create table new_table_name 
as
select column_name,[more columns] from Existed_table;

Example:

create table dept
as
select empno, ename from emp;

If the table already exists:

insert into new_tablename select columns_list from Existed_table;

I guess you will get ORA-01741: illegal zero-length identifier if you use the following

SELECT "" AS Contact  FROM Customers;

And if you use the following 2 statements, you will be getting the same null value populated in the column.

SELECT '' AS Contact FROM Customers; OR SELECT null AS Contact FROM Customers;

This answer may come a bit late but I have found an acceptable solution. My approach is a bit similar to @Mani one but I think mine is a bit more easy to understand.

Putting it into global hook and into the component itself are not ideal, global hook checks every request so you will need to write a lot of conditions to check if it should be 404 and window.location.href in the component creation is too late as the request has gone into the component already and then you take it out.

What I did is to have a dedicated url for 404 pages and have a path * that for everything that not found.

{ path: '/:locale/404', name: 'notFound', component: () => import('pages/Error404.vue') },
{ path: '/:locale/*', 
  beforeEnter (to) {
    window.location = `/${to.params.locale}/404`
  }
}

You can ignore the :locale as my site is using i18n so that I can make sure the 404 page is using the right language.

On the side note, I want to make sure my 404 page is returning httpheader 404 status code instead of 200 when page is not found. The solution above would just send you to a 404 page but you are still getting 200 status code. To do this, I have my nginx rule to return 404 status code on location /:locale/404

server {
    listen                      80;
    server_name                 localhost;

    error_page  404 /index.html;
    location ~ ^/.*/404$ {
      root   /usr/share/nginx/html;
      internal;
    }

    location / {
      root   /usr/share/nginx/html;
      index  index.html index.htm;
      try_files $uri $uri/ @rewrites;
    }

    location @rewrites {
      rewrite ^(.+)$ /index.html last;
    }

    location = /50x.html {
      root   /usr/share/nginx/html;
    }
}

It is not possible to find the number of elements in an array unless it is a character array. Consider the below example:

int main()
{
    int arr[100]={1,2,3,4,5};
    int size = sizeof(arr)/sizeof(arr[0]);
    printf("%d", size);
    return 1;
}

The above value gives us value 100 even if the number of elements is five. If it is a character array, you can search linearly for the null string at the end of the array and increase the counter as you go through.

The solution with TextBoxFor is OK, but if you don't want to see the field like EditBox stylish (it might be a little confusing for the user) involve changes as follows:

1. Razor code before changes

   <div class="editor-field">
        @Html.EditorFor(model => model.Text)
        @Html.ValidationMessageFor(model => model.Text)
   </div>
   

2. After changes

   <!-- New div display-field (after div editor-label) -->
   <div class="display-field">
       @Html.DisplayFor(model => model.Text)
   </div>
   
   <div class="editor-field">
       <!-- change to HiddenFor in existing div editor-field -->
       @Html.HiddenFor(model => model.Text)
       @Html.ValidationMessageFor(model => model.Text)
   </div>
   

Generally, this solution prevents field from editing, but shows value of it. There is no need for code-behind modifications.

You can use jQuery's $.map.

var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' },
keys = $.map(foo, function(v, i){
  return i;
});

Nano is 10^-9 and milli 10^-3. Hence, we can use the three first characters of nanoseconds to get the milliseconds:

date +%s%3N

From man date:

%N nanoseconds (000000000..999999999)

%s seconds since 1970-01-01 00:00:00 UTC

Source: Server Fault's How do I get the current Unix time in milliseconds in Bash?.

They are equivalent. See this code:

mySlice1 := make([]int, 0)
mySlice2 := []int{}
fmt.Println("mySlice1", cap(mySlice1))
fmt.Println("mySlice2", cap(mySlice2))

Output:

mySlice1 0
mySlice2 0

Both slices have 0 capacity which implies both slices have 0 length (cannot be greater than the capacity) which implies both slices have no elements. This means the 2 slices are identical in every aspect.

You need to delete the deployment, which should in turn delete the pods and the replica sets https://github.com/kubernetes/kubernetes/issues/24137

To list all deployments:

kubectl get deployments --all-namespaces

Then to delete the deployment:

kubectl delete -n NAMESPACE deployment DEPLOYMENT

Where NAMESPACE is the namespace it's in, and DEPLOYMENT is the name of the deployment.

In some cases it could also be running due to a job or daemonset. Check the following and run their appropriate delete command.

kubectl get jobs

kubectl get daemonsets.app --all-namespaces

kubectl get daemonsets.extensions --all-namespaces

If all you want to do is conditionally show or hide a <div>, then you could declare it as an <asp:panel > (renders to html as a div tag) and set it's .Visible property.

Find your PHP.ini and look for XDebug.

normally in Ubuntu its path is

/etc/php5/apache2/php.ini  

Make following changes (Better to just comment them by adding ; at the beginning )

xdebug.remote_autostart=0
xdebug.remote_enable=0
xdebug.profiler_enable=0

then restart your server again for Ubuntu

sudo service apache2 restart

Now that I've separated the classes to .h and .cpp files do I need to use a makefile or can I still use the "g++ main.cpp" command?

Compiling several files at once is a poor choice if you are going to put that into the Makefile.

Normally in a Makefile (for GNU/Make), it should suffice to write that:

# "all" is the name of the default target, running "make" without params would use it
all: executable1

# for C++, replace CC (c compiler) with CXX (c++ compiler) which is used as default linker
CC=$(CXX)

# tell which files should be used, .cpp -> .o make would do automatically
executable1: file1.o file2.o

That way make would be properly recompiling only what needs to be recompiled. One can also add few tweaks to generate the header file dependencies - so that make would also properly rebuild what's need to be rebuilt due to the header file changes.

Additional to the above - the QEMU website has good documentation about setting up an ARM based emulator: http://qemu.weilnetz.de/qemu-doc.html#ARM-System-emulator

From the comments:

import msvcrt # built-in module

def kbfunc():
    return ord(msvcrt.getch()) if msvcrt.kbhit() else 0

Thanks for the help. I ended up writing a C DLL called PyKeyboardAccess.dll and accessing the crt conio functions, exporting this routine:

#include <conio.h>

int kb_inkey () {
   int rc;
   int key;

   key = _kbhit();

   if (key == 0) {
      rc = 0;
   } else {
      rc = _getch();
   }

   return rc;
}

And I access it in python using the ctypes module (built into python 2.5):

import ctypes
import time

#
# first, load the DLL
#


try:
    kblib = ctypes.CDLL("PyKeyboardAccess.dll")
except:
    raise ("Error Loading PyKeyboardAccess.dll")


#
# now, find our function
#

try:
    kbfunc = kblib.kb_inkey
except:
    raise ("Could not find the kb_inkey function in the dll!")


#
# Ok, now let's demo the capability
#

while 1:
    x = kbfunc()

    if x != 0:
        print "Got key: %d" % x
    else:
        time.sleep(.01)

You may use the below code to write, for example an image to S3 in 2019. To be able to connect to S3 you will have to install AWS CLI using command pip install awscli, then enter few credentials using command aws configure:

        self.client = boto3.client('s3')
        self.bucket_name = BUCKET_NAME
        self.posters_base_path = POSTERS_BASE_PATH

    def __download_image(self, url):
        manager = urllib3.PoolManager()
        try:
            res = manager.request('GET', url)
        except Exception:
            print("Could not download the image from URL: ", url)
            raise cex.ImageDownloadFailed
        return BytesIO(res.data)  # any file-like object that implements read()

    def upload_image(self, url):
        try:
            image_file = self.__download_image(url)
        except cex.ImageDownloadFailed:
            raise cex.ImageUploadFailed

        extension = Path(url).suffix
        id = uuid.uuid1().hex + extension
        final_path = self.posters_base_path + "/" + id

on duplicate key update, or insert ignore can be viable solutions with MySQL.

Example of on duplicate key update update based on mysql.com

INSERT INTO table (a,b,c) VALUES (1,2,3)
  ON DUPLICATE KEY UPDATE c=c+1;

UPDATE table SET c=c+1 WHERE a=1;

Example of insert ignore based on mysql.com

INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name [(col_name,...)]
    {VALUES | VALUE} ({expr | DEFAULT},...),(...),...
    [ ON DUPLICATE KEY UPDATE
      col_name=expr
        [, col_name=expr] ... ]

Or:

INSERT [LOW_PRIORITY | DELAYED | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name
    SET col_name={expr | DEFAULT}, ...
    [ ON DUPLICATE KEY UPDATE
      col_name=expr
        [, col_name=expr] ... ]

Or:

INSERT [LOW_PRIORITY | HIGH_PRIORITY] [IGNORE]
    [INTO] tbl_name [(col_name,...)]
    SELECT ...
    [ ON DUPLICATE KEY UPDATE
      col_name=expr
        [, col_name=expr] ... ]

I think you should try with :

While Semaphore initialization :

Semaphore semaphore = new Semaphore(1, true);

And in your Runnable Implementation

try 
{
   semaphore.acquire(1);
   // do stuff

} 
catch (Exception e) 
{
// Logging
}
finally
{
   semaphore.release(1);
}

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

I realize I'm late to the party, but there is a simple way to let the browser parse a url for you without a regex:

var a = document.createElement('a');
a.href = 'http://www.example.com:123/foo/bar.html?fox=trot#foo';

['href','protocol','host','hostname','port','pathname','search','hash'].forEach(function(k) {
    console.log(k+':', a[k]);
});

/*//Output:
href: http://www.example.com:123/foo/bar.html?fox=trot#foo
protocol: http:
host: www.example.com:123
hostname: www.example.com
port: 123
pathname: /foo/bar.html
search: ?fox=trot

Many answers here! What I use without reinventing the wheel - the most famous plugins (that are not going to die any time soon and are used by many people) to be ultra fast and geeky.

• ctrlpvim/ctrlp.vim - to find file by name fuzzy search by its location or just its name
• jlanzarotta/bufexplorer - to browse opened buffers (when you do not remember how many files you opened and modified recently and you do not remember where they are, probably because you searched for them with Ag)
• rking/ag.vim to search the files with respect to gitignore
• scrooloose/nerdtree to see the directory structure, lookaround, add/delete/modify files

EDIT: Recently I have been using dyng/ctrlsf.vim to search with contextual view (like Sublime search) and I switched the engine from ag to ripgrep. The performance is outstanding.

EDIT2: Along with CtrlSF you can use mg979/vim-visual-multi, make changes to multiple files at once and then at the end save them in one go.

I like to used this method the most, it will auto select the first column to the last column being used. However, if the last cell in the first row or the last cell in the first column are empty, this code will not calculate properly. Check the link for other methods to dynamically select cell range.

Sub DynamicRange()
'Best used when first column has value on last row and first row has a value in the last column

Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range

Set sht = Worksheets("Sheet1")
Set StartCell = Range("A1")

'Find Last Row and Column
  LastRow = sht.Cells(sht.Rows.Count, StartCell.Column).End(xlUp).Row
  LastColumn = sht.Cells(StartCell.Row, sht.Columns.Count).End(xlToLeft).Column

'Select Range
  sht.Range(StartCell, sht.Cells(LastRow, LastColumn)).Select

End Sub

Probably not exactly your issue..

Do you have any spaces in your package path? You should wrap it up in double quotes to be safe, otherwise it can be taken as two separate arguments

sudo installer -store -pkg "/User/MyName/Desktop/helloWorld.pkg" -target /

To find all files modified in the last 24 hours (last full day) in a particular specific directory and its sub-directories:

find /directory_path -mtime -1 -ls

Should be to your liking

The - before 1 is important - it means anything changed one day or less ago. A + before 1 would instead mean anything changed at least one day ago, while having nothing before the 1 would have meant it was changed exacted one day ago, no more, no less.

You could implement a onActivityResult in Class B as well and launch Class C using startActivityForResult. Once you get the result in Class B then set the result there (for Class A) based on the result from Class C. I haven't tried this out but I think this should work.

Another thing to look out for is that Activity A should not be a singleInstance activity. For startActivityForResult to work your Class B needs to be a sub activity to Activity A and that is not possible in a single instance activity, the new Activity (Class B) starts in a new task.

You can use PycURL on Python 2 and 3.

import pycurl

FILE_DEST = 'pycurl.html'
FILE_SRC = 'http://pycurl.io/'

with open(FILE_DEST, 'wb') as f:
    c = pycurl.Curl()
    c.setopt(c.URL, FILE_SRC)
    c.setopt(c.WRITEDATA, f)
    c.perform()
    c.close()

Here is another way, by rotating element with the scrollbar for 180deg, wrapping it's content into another element, and rotating that wrapper for -180deg. Check the snippet below

div {_x000D_
  display: inline-block;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 2px solid black;_x000D_
  margin: 15px;_x000D_
}_x000D_
#vertical {_x000D_
  direction: rtl;_x000D_
  overflow-y: scroll;_x000D_
  overflow-x: hidden;_x000D_
  background: gold;_x000D_
}_x000D_
#vertical p {_x000D_
  direction: ltr;_x000D_
  margin-bottom: 0;_x000D_
}_x000D_
#horizontal {_x000D_
  direction: rtl;_x000D_
  transform: rotate(180deg);_x000D_
  overflow-y: hidden;_x000D_
  overflow-x: scroll;_x000D_
  background: tomato;_x000D_
  padding-top: 30px;_x000D_
}_x000D_
#horizontal span {_x000D_
  direction: ltr;_x000D_
  display: inline-block;_x000D_
  transform: rotate(-180deg);_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

Yes, let's use Select as an example

sample code: Columns("A").select

How to loop through Columns:

Method 1: (You can use index to replace the Excel Address)

For i = 1 to 100
    Columns(i).Select
next i

Method 2: (Using the address)

For i = 1 To 100
 Columns(Columns(i).Address).Select
Next i

EDIT: Strip the Column for OP

columnString = Replace(Split(Columns(27).Address, ":")(0), "$", "")

e.g. you want to get the 27th Column --> AA, you can get it this way

Say your list has 100 elements and you want to pick 50 of them in a random way. Here are the steps to follow:

1. Import the libraries
2. Create the seed for random number generator, I have put it at 2
3. Prepare a list of numbers from which to pick up in a random way
4. Make the random choices from the numbers list

Code:

from random import seed
from random import choice

seed(2)
numbers = [i for i in range(100)]

print(numbers)

for _ in range(50):
    selection = choice(numbers)
    print(selection)

Command-line arguments are passed in the first String[] parameter to main(), e.g.

public static void main( String[] args ) {
}

In the example above, args contains all the command-line arguments.

The short, sweet answer to the question posed is:

public static void main( String[] args ) {
    if( args.length > 0 && args[0].equals( "a" ) ) {
        // first argument is "a"
    } else {
        // oh noes!?
    }
}

UPDATE: There are better options than my original answer. This works outside of MVC quite well but it's better to stick with the built-in methods of returning image content. See up-voted answers.

You certainly can. Try out these steps:

1. Load the image from disk in to a byte array
2. cache the image in the case you expect more requests for the image and don't want the disk I/O (my sample doesn't cache it below)
3. Change the mime type via the Response.ContentType
4. Response.BinaryWrite out the image byte array

Here's some sample code:

string pathToFile = @"C:\Documents and Settings\some_path.jpg";
byte[] imageData = File.ReadAllBytes(pathToFile);
Response.ContentType = "image/jpg";
Response.BinaryWrite(imageData);

Hope that helps!

You can use continue

if condition:
    continue
else:
    #do something

The error is legitimate and may prevent your app from crashing. You typed makes as an array but it can also be undefined.

You have 2 options (instead of disabling the typescript's reason for existing...):

1. In your case the best is to type makes as possibily undefined.

makes?: any[]
// or
makes: any[] | undefined

In this case the compiler will inform you whenever you try to access to makes that it could be undefined. For exemple if the // <-- Not ok lines below are executed before getMakes finished or if getMakes fails, your app will crash and a runetime error will be thrown.

makes[0] // <-- Not ok
makes.map(...) // <-- Not ok

if (makes) makes[0] // <-- Ok
makes?.[0] // <-- Ok
(makes ?? []).map(...) // <-- Ok

2. You can assume that it will never fail and that you will never try to access it before initialization by writing the code below (risky!). So the compiler won't take care about it.

makes!: any[]

Change the property WindowState to System.Windows.Forms.FormWindowState.Maximized, in some cases if the older answers doesn't works.

So the window will be maximized, and the other parts are in the other answers.

Sometimes it is useful to temporarily change Git's case sensitivity.

Method #1 - Change case sensitivity for a single command:

git -c core.ignorecase=true checkout mybranch to turn off case-sensitivity for a single checkout command. Or more generally: git -c core.ignorecase= <<true or false>> <<command>>. (Credit to VonC for suggesting this in the comments.)

Method #2 - Change case sensitivity for multiple commands:

To change the setting for longer (e.g. if multiple commands need to be run before changing it back):

1. git config core.ignorecase (this returns the current setting, e.g. false).
2. git config core.ignorecase <<true or false>> - set the desired new setting.
3. ...Run multiple other commands...
4. git config core.ignorecase <<false or true>> - set config value back to its previous setting.

>>> import numpy as np
>>> a = np.random.randint(0, 5, size=(5, 4))
>>> a
array([[4, 2, 1, 1],
       [3, 0, 1, 2],
       [2, 0, 1, 1],
       [4, 0, 2, 3],
       [0, 0, 0, 2]])
>>> b = a < 3
>>> b
array([[False,  True,  True,  True],
       [False,  True,  True,  True],
       [ True,  True,  True,  True],
       [False,  True,  True, False],
       [ True,  True,  True,  True]], dtype=bool)
>>> 
>>> c = b.astype(int)
>>> c
array([[0, 1, 1, 1],
       [0, 1, 1, 1],
       [1, 1, 1, 1],
       [0, 1, 1, 0],
       [1, 1, 1, 1]])

You can shorten this with:

>>> c = (a < 3).astype(int)

String.matches is the way to do pattern matching in the regex sense.

But as a handy aside, word.firstLetter in real Scala code looks like:

word(0)

Scala treats Strings as a sequence of Char's, so if for some reason you wanted to explicitly get the first character of the String and match it, you could use something like this:

"Cat"(0).toString.matches("[a-cA-C]")
res10: Boolean = true

I'm not proposing this as the general way to do regex pattern matching, but it's in line with your proposed approach to first find the first character of a String and then match it against a regex.

EDIT: To be clear, the way I would do this is, as others have said:

"Cat".matches("^[a-cA-C].*")
res14: Boolean = true

Just wanted to show an example as close as possible to your initial pseudocode. Cheers!

One Unix based systems (Linux, BSD, Mac OS X), the default identity is stored in the directory $HOME/.ssh, in 2 files: private key: $HOME/.ssh/id_rsa public key: $HOME/.ssh/id_rsa.pub When you use ssh without option -i, it uses the default private key to authenticate with remote system.

If you have another private key you want to use, for example $HOME/.ssh/deploy_key, you have to use ssh -i ~/.ssh/deploy_key ...

It is annoying. You can add the following lines in to your $HOME/.bash_profile : ssh-add ~/.ssh/deploy_key ssh-add ~/.ssh/id_rsa

So each time you use ssh or git or scp (basically ssh too), you don't have to use option -i anymore.

You can add as many keys as you like in the file $HOME/.bash_profile.

Just as a addition. You can find the Catalina Paths in

->RUN->RUN CONFIGURATIONS->APACHE TOMCAT->ARGUMENTS

In the VM Arguments the Paths are listed and changeable

Look in your .svn folder, there will be a file in it called lock. Delete that file and you will be able to update. There may be more lock files in the .svn directory of each subdirectory. They will need deleting also. This could be done as a batch quite simply from the command line with e.g.

find . -name 'lock' -exec rm -v {} \;

Note that you are manually editing files in the .svn folder. They have been put there for a reason. That reason might be a mistake, but if not you could be damaging your local copy.

That information is stored in the ALL_TAB_COLUMNS system table:

1. Find out where Git thinks 'origin/master' is using git-remote

git remote show origin

..which will return something like..

* remote origin
  URL: [email protected]:~/something.git
  Remote branch merged with 'git pull' while on branch master
    master
  Tracked remote branch
    master

A remote is basically a link to a remote repository. When you do..

git remote add unfuddle [email protected]/myrepo.git
git push unfuddle

..git will push changes to that address you added. It's like a bookmark, for remote repositories.

When you run git status, it checks if the remote is missing commits (compared to your local repository), and if so, by how many commits. If you push all your changes to "origin", both will be in sync, so you wont get that message.

2. If it's somewhere else, how do I turn my laptop into the 'origin/master'?

There is no point in doing this. Say "origin" is renamed to "laptop" - you never want to do git push laptop from your laptop.

If you want to remove the origin remote, you do..

git remote rm origin

This wont delete anything (in terms of file-content/revisions-history). This will stop the "your branch is ahead by.." message, as it will no longer compare your repository with the remote (because it's gone!)

One thing to remember is that there is nothing special about origin, it's just a default name git uses.

Git does use origin by default when you do things like git push or git pull. So, if you have a remote you use a lot (Unfuddle, in your case), I would recommend adding unfuddle as "origin":

git remote rm origin
git remote add origin [email protected]:subdomain/abbreviation.git

or do the above in one command using set-url:

git remote set-url origin [email protected]:subdomain/abbreviation.git

Then you can simply do git push or git pull to update, instead of git push unfuddle master

Here are a few points:

• You could consider upgrading to HttpClient 4 (generally speaking, if you can, I don't think version 3 is still actively supported).

• A 500 status code is a server error, so it might be useful to see what the server says (any clue in the response body you're printing?). Although it might be caused by your client, the server shouldn't fail this way (a 4xx error code would be more appropriate if the request is incorrect).

• I think setDoAuthentication(true) is the default (not sure). What could be useful to try is pre-emptive authentication works better:

  client.getParams().setAuthenticationPreemptive(true);
  

Otherwise, the main difference between curl -d "" and what you're doing in Java is that, in addition to Content-Length: 0, curl also sends Content-Type: application/x-www-form-urlencoded. Note that in terms of design, you should probably send an entity with your POST request anyway.

You can inspect elements of a website in your Android device using Chrome browser.

Open your Chrome browser and go to the website you want to inspect.

Go to the address bar and type "view-source:" before the "HTTP" and reload the page.

The whole elements of the page will be shown.

Above methods didn´t work for me. This did:

  Dim arrayIsNothing As Boolean

    On Error Resume Next
    arrayIsNothing = IsNumeric(UBound(YOUR_ARRAY)) And False
    If Err.Number <> 0 Then arrayIsNothing = True
    Err.Clear
    On Error GoTo 0

    'Now you can test:
    if arrayIsNothing then ...

You can also do this, for readability's sake

boolean passwordVerified=(pword.equals(pwdRetypePwd.getText());

if(!passwordVerified ){
    txtaError.setEditable(true);
    txtaError.setText("*Password didn't match!");
    txtaError.setForeground(Color.red);
    txtaError.setEditable(false);
}else{
    addNewUser();
}
return passwordVerified;

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

If you want your program to crash and not know the reason, then go ahead and trust the programmers and c basic error handling.

I think it's best to build in some kind of error reporting, call it debug mode, turn it off when your want best performance and turn it on when you want to debug a issue. Hopefully you can hit it again.

There will be bugs, the question is how do you want to spend your days and nights looking for them.

For SOCK_STREAM socket, the buffer size does not really matter, because you are just pulling some of the waiting bytes and you can retrieve more in a next call. Just pick whatever buffer size you can afford.

For SOCK_DGRAM socket, you will get the fitting part of the waiting message and the rest will be discarded. You can get the waiting datagram size with the following ioctl:

#include <sys/ioctl.h>
int size;
ioctl(sockfd, FIONREAD, &size);

Alternatively you can use MSG_PEEK and MSG_TRUNC flags of the recv() call to obtain the waiting datagram size.

ssize_t size = recv(sockfd, buf, len, MSG_PEEK | MSG_TRUNC);

You need MSG_PEEK to peek (not receive) the waiting message - recv returns the real, not truncated size; and you need MSG_TRUNC to not overflow your current buffer.

Then you can just malloc(size) the real buffer and recv() datagram.

To illustrate Nippysaurus's answer: If you are going to add the new items to the list and want to process the newly added items too during the same enumeration then you can just use for loop instead of foreach loop, problem solved :)

var list = new List<YourData>();
... populate the list ...

//foreach (var entryToProcess in list)
for (int i = 0; i < list.Count; i++)
{
    var entryToProcess = list[i];

    var resultOfProcessing = DoStuffToEntry(entryToProcess);

    if (... condition ...)
        list.Add(new YourData(...));
}

For runnable example:

void Main()
{
    var list = new List<int>();
    for (int i = 0; i < 10; i++)
        list.Add(i);

    //foreach (var entry in list)
    for (int i = 0; i < list.Count; i++)
    {
        var entry = list[i];
        if (entry % 2 == 0)
            list.Add(entry + 1);

        Console.Write(entry + ", ");
    }

    Console.Write(list);
}

Output of last example:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 3, 5, 7, 9,

1-make 1 shape for Button right click on drawable nd new drawable resource file . change Root element to shape and make your shape.

enter image description here

2-now make 1 copy from your shape and change name and change solid color. enter image description here

3-right click on drawable and new drawable resource file just set root element to selector.

go to file and set "state_pressed"

<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:state_pressed="true"android:drawable="@drawable/YourShape1"/>
<item android:state_pressed="false" android:drawable="@drawable/YourShape2"/>

</selector>

4-the end go to xml layout and set your Button background "your selector"

(sorry for my english weak)

You can use >> to print in another file.

echo "hello" >> logfile.txt

Adapted from Not So Frequently Asked Questions:

std::string data = "Abc";
std::transform(data.begin(), data.end(), data.begin(),
    [](unsigned char c){ return std::tolower(c); });

You're really not going to get away without iterating through each character. There's no way to know whether the character is lowercase or uppercase otherwise.

If you really hate tolower(), here's a specialized ASCII-only alternative that I don't recommend you use:

char asciitolower(char in) {
    if (in <= 'Z' && in >= 'A')
        return in - ('Z' - 'z');
    return in;
}

std::transform(data.begin(), data.end(), data.begin(), asciitolower);

Be aware that tolower() can only do a per-single-byte-character substitution, which is ill-fitting for many scripts, especially if using a multi-byte-encoding like UTF-8.

ManagementFactory.getThreadMXBean().getThreadCount() doesn't limit itself to thread groups as Thread.activeCount() does.

git rebase -i master

you will get the editor vm open and msgs something like this

Pick 2994283490 commit msg1
f 7994283490 commit msg2
f 4654283490 commit msg3
f 5694283490 commit msg4
#Some message 
#
#some more

Here I have changed pick for all the other commits to "f" (Stands for fixup).

git push -f origin feature/feature-branch-name-xyz

this will fixup all the commits to one commit and will remove all the other commits . I did this and it helped me.
